4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o model/src & gmredi K3D:
8      - add frictionHeating field to pickup-files (for synchronous time-stepping)
9      - move ALLOW_EDDYPSI block out of DYNVARS.h and merge it into FFIELDS.h
10      - rename uMean,vMean --> uEulerMean,vEulerMean (+ change diagnostics name
11        and name in pickup file).
12      - fix arguments of few DIAGNOSTICS_FILL calls in gmredi_k3d.F
13    o model/src:
14      - move (from ini_forcing.F) initialisation of all arrays in header file
15        FFIELDS.h into new S/R ini_ffields.F ; this fix broken restart
16        (since Nov 2012) with option selectAddFluid=1.
17    o pkg/shelfice:
18      - change units (+ document) of newly added field "shelfIceMassDynTendency"
19      - upgrade from _RS to _RL shelficeMass & shelficeLoadAnomaly arrays.
20    o pkg/obcs: re-organize obcs_calc_stevens.F to prepare for passive tracers
21    o pkg/seaice: two new runtime parameters:
22      - SEAICE_cStar replaces the hard wired "20" in the strength formulation,
23        long overdue
24      - SEAICE_tensilFac: preparation for Koenig-Beatty+Holland (2012)
25        parameterization of tensil stress for fast ice (does not do anything yet)
26    o pkg/seaice/seaice_check.F: left over from restricted addtive Schwarz method
27        for LSR: move checking overlaps out of JFNK-if-block
28    o pkg/atm_phys:
29      - move copy of grid and dynamical fields out of atm_phys_driver.F into
30        new S/R ATM_PHYS_DYN2PHYS.
31      - fix level height for Linear Free-Surf case (to be consistent with
32        fixed-in-time pressure levels).
33    o pkg/mom_common (bottomdrag):
34      - average bottomDragFld (ALLOW_BOTTOMDRAG_CONTROL) from grid-cell center
35        to correct location (U & V point) in S/R MOM_U/V_BOTTOMDRAG;
36        update output (adm & tlm) of experiment global_ocean.90x40x15.bottomdrag.
37    o pkg/shelfice (u/v_drag):
38      - add one argument (the other velocity component) to S/R SHELFICE_U/V_DRAG;
39      - use SHELFICEDragLinear & SHELFICEDragQuadratic in shelfice_v_drag.F
40        (now similar to shelfice_u_drag.F)
41      - remove condition on bottomDragTerms when calling SHELFICE_U/V_DRAG
42        from mom_vecinv.F (similar to mom_fluxform calls).
43    o pkg/mom_common (bottomdrag):
44      - add one argument (the other velocity component) to S/R MOM_U/V_BOTTOMDRAG;
45      - add options for alternative discretisation of velocity norm in quadratic
46        bottom drag: averaging of grid-cell-center KE to U.point and V.point
47        (selectBotDragQuadr=0, original code) can produce noisy patterns; this
48        improves when averaging only the other component (e.g. vVel for U bottom
49        drag) using wet-point method (selectBotDragQuadr=2) or not (=1).
50      - add options (bottomVisc_pCell) to account for partial-cell in bottom
51        friction (no-slip BC) thus getting the true distance from the bottom;
52        off by default since this also reduces model stability (explicit bottom
53        friction). Changes produce different machine truncation with linear-drag
54        + no-slip BC: update output of experiments exp4.stevens (10 digits) and
55        front_relax (bvp & mxl, 10 & 11 digits).
56    o model/src & mom pkgs:
57      - add one more level to vertical viscosity local arrays (Nr+1, previously Nr)
58        since no-slip bottom BC uses viscosity @ k+1 to update velocity @ level k
59      - for now and until vertical mixing scheme are updated to fill up level Nr+1,
60        just copy level Nr value to level Nr+1.
61    o doc:
62      - add notes form Abhisek Chakraborty on how to close Heat & Salt budgets.
63    o pkg/streamice:
64      - shelfice_init_varia.F, shelfice_init_fixed.F, shelfice_readparms.F,
65        SHELFICE.h: move array shelficemass to init_varia, initialise
66        from array shelficemassinit, which is set in init_fixed and
67        has option to be set from file; introduce array
68        shelficeMassDynTend array, set thru file in init_fixed
69      - NEW FILE: shelfice_step_icemass.F: update shelficemass from either
70        shelfIceFreshWaterFlux and shelficeMassDynTend or H_streamice in
71        pkg/streamice
72      - shelfice_thermodynamics.F: call shelfice_step_icemass if
73        SHELFICEMassStepping = .true.
74      - shelfice_ad_diff.list: add new subroutine shelfice_step_icemass.f
75    
76    checkpoint65h (2014/12/17)
77    o verification/global_ocean.90x40x15, global_ocean_ebm:
78      - update to generic controls.
79    o pkg/ctrl:
80      - ctrl_map_ini_genarr.F: test for igen>0
81      - ctrl_init_variables.F: add call to CTRL_MAP_INI_GENTIM2D.
82      - move gentim2d part of ctrl_map_ini_genarr.F to
83        new separate routine : ctrl_map_ini_gentim2d.F
84      - ctrl_cost_driver.F,ctrl_init.F ctrl_map_ini_genarr.F:
85        add time variable weights and cyclic controls (time mean,
86        seasonal cycle, etc) capabilities to gentim2d
87    o pkg/ecco:
88      - move reading of error, conversion to weights from
89        ecco_cost_init_fixed.F to ecco_toolbox.F (ecco_readwei)
90    o global_oce_llc90, cs32:
91      - activte sbo.
92      - CTRL_SIZE.h : add maxCtrlProc.
93      - activate the new genctrl capabilities.
94      - update following reorganization of global_oce_input_fields.tar.gz  
95    o pkg/ctrl/ctrl_ad_diff.list:
96      - add missing ctrl_init_rec.f
97    o tools/OAD_support/keepOriginal:
98      - add ctrl_init_rec.F
99    o model/src/the_main_loop.F, pkg/ctrl/ctrl_map_ini_genarr.F:
100      - avoid recomputations of xx_gentim2d_dummy.
101    o momentum diagnostics:
102      - move filling of diagnostics Um_Diss & Vm_Diss from mom_fluxform.F and
103        mom_vecinv.F to timestep.F (to include Smag-3D contribution).
104    o pkg/seaice/seaice_lsr.F:
105      - fix computation of BU/BV, make sure they are non-zero, only necessary
106        for cubed sphere exchanges and SEAICE_OLx/y>0.
107        This makes calling s/r fill_cs_corner_rl obsolete (removed).
108    o verification/global_ocean.cs32x15/input.seaice
109      - add test for strong implicit coupling and restricted addtive Schwarz
110        methods for LSR
111      - update results/output.seaice.txt
112    o verification/tutorial_global_oce_biogeo:
113      - AD & OAD set-up: switch off ALLOW_OLD_VIRTUALFLUX (like in fwd set-up)
114        and set PTRACERS_EvPrRn(1,2) to zero (for DIC & ALK);
115        update output_adm,_oadm,_tlm.txt
116    o pkg/dic:
117      - change default to "#undef ALLOW_OLD_VIRTUALFLUX" in DIC_OPTIONS.h
118      - add a stop when ALLOW_OLD_VIRTUALFLUX is defined and PTRACERS_EvPrRn
119        for tracer 1 & 2 is set (to avoid double counting of dilution effect).
120    o verification/tutorial_global_oce_biogeo:
121      - AD & OAD set-up: do not set PTRACERS_EvPrRn for tracer 1 & 2 since
122        dilution is already added by pkg/dic ALLOW_OLD_VIRTUALFLUX ;
123        update output_adm,_oadm,_tlm.txt
124    o eesupp/src:
125      - add fill_cs_corner_rl.F (_RL-copy of fill_cs_corner_rs.F)
126        and call it in seaice_lsr when using nonzero SEAICE_OLx/y
127    o pkg/seaice: introduce strongly implicit coupling, intended for stabilizing
128      LSR (following Hutchings et al. 2004)
129      - introduce zetaZ as a global variable (requires adjustments in
130        seaice_evp.F and seaice_jfnk.F) and compute analoguously to etaZ
131        in seaice_calc_viscosities.F
132      - new flag SEAICEuseStrImpCpl (default off)
133      - add new terms zetaZ*du/dy and zetaZ*dv/dx on both sides of the
134        momentum equations
135      - JFNK-solver (preconditioner) adjusted to allow using this method
136        (where it does not have any positive effect)
137    o pkg/seaice
138      - add overlap for restrictive additive Schwartz method also to LSR, but
139        turn it off by default (because it only seems to work for non-cubed
140        sphere/llc topologies)
141    o pkg/autodiff
142      - add extra exchanges in addummy_in_steppging also for mnc output
143    o pkg/seaice:
144      - add extra exchanges before dumping adjoint fields in seaice_ad_dump.F
145        to avoid stripes in the adjoint output (similar to addummy_in_stepping.F)
146    o pkg/obcs:
147      - add option to specify domain-connected piece Id along OB though files
148        (for now, only used to diagnose PhiVel; default =1 -> global correction)
149      - modify obcs_diag_balance.F to process each connected-part separately;
150        exclude OB where Id = 0 but keep the full divergence there (-> constant
151        Psi along this portion of OB and all inflow derived from grad(Phi))
152      - add example of OB-conect files in verification/so_box_biogeo/input.
153    o pkg/diagnostics:
154      - improve treatment of Open-Boundaries in Velocity-Potential calculation:
155      a) use non zero matrix element across OB and solve for Phi 1 grid point
156         outside OB (i.e, where tracer OBCS are applied).
157      b) global imbalance of inFlow/outFlow across OB: instead of modifying
158         velocity across OB, spread it uniformly along the OB in the RHS.
159    
160    checkpoint65g (2014/11/19)
161    o pkg/diagnostcis:
162      - add preconditioner off-diagonal factor (diagCG_pcOffDFac) as run-time param
163    o pkg/my82,pp81,kl10:
164      - fix ALLOW_3D_DIFFKR implementation (previously had no effect): use 3-D
165        field diffKr as background diffusivity to set minimum diffusivity value.
166    o pkg/seaice:
167      - add new parameter SEAICEuseEVPrev (for revisited EVP by
168        Bouillon et al 2013)
169      - add SEAICE_evpAlpha/Beta to namelist
170      - modify seaice_evp code to able to use SEAICEuseEVPrev. These changes
171        involve trivial re-ordering of divisions/multiplications that should not
172        have any effects, but ... they do change the results of lab_sea.hb87 so
173        that only 2 digits of agreement remain, in line with the general
174        instability/fragility of the evp-code. For now, I do not care and just
175        update the verification experiment
176    o pkg/ctrl : add generic pre-processing (xx_genarr2d_preproc etc)
177      - remove xx_genarr2d_numsmooth etc
178      - use xx_genarr2d_preproc etc instead
179      - carry out smooth_correl2D at initialization stage rather than during
180        time stepping.
181      - get smoothOpNb from xx_gentim2d_preproc
182    o global_oce_cs32 :
183      - add test of generic ecco capabilities.
184    o pkg/exf/exf_getsurfacefluxes.F :
185      - add to tmpUE/tmpVN rather than re-initializing them (conventional behavior).
186    o pkg/ctrl,ecco :
187      - omit un-necessary arguments to ctrl_cost_gen.F unless ECCO_CTRL_DEPRECATED
188        is defined.
189    o pkg/seaice: add diagnostics for Delta (deformation parameter)
190    o model/src:
191      - when ALLOW_3D_DIFFKR is defined, add a Warning if any of the vertical
192        diffusivity (background) is specified but ignored.
193    o verification:
194      - in testreport, convert hostname to lower case for default output dir name
195    o model, pkg : add useCTRL, useECCO parameters (on/off run time switch).
196    o pkg/dic: add modifications from Hajoon:
197      - add iron sedimentation flux function of the flux of PO4 out of bottom layer
198      - light attenuation: add self-shading effect by climatological Chlorophyll
199        (read from file).
200    o pkg/seaice/seaice_preconditioner.F : fix cpp flags, so that code also
201        compiles when SEAICE_ALLOW_DYNAMICS is undefined
202    o global_oce_llc90,cs32 : ecco_v4 verification exps now use separate
203        AUTODIFF_OPTIONS.h, CTRL_OPTIONS.h, ECCO_OPTIONS.h rather than
204        ECCO_CPPOPTIONS.h (i.e. replacing the deprecated, circumvoluted,
205        approach where CPP_OPTIONS.h includes an omnipotent
206        ECCO_CPPOPTIONS.h that superseeds pkgs '_OPTIONS.h').
207    o pkg/ctrl/ctrl_map_ini_genarr.F : include GMREDI_OPTIONS.h where
208        ALLOW_3D_KAPGM, ALLOW_3D_KAPREDI (to be added later) belong.
209    o pkg/seaice/SEAICE_SIZE.h : replace ALLOW_AUTODIFF_TAMC with ALLOW_AUTODIFF
210        to avoid needing AUTODIFF_OPTIONS.h anytime SEAICE_SIZE.h is included
211        (it seems that THSICE_SIZE.h, PTRACERS_SIZE.h have the same issue...)
212    o model/src, pkg/smooth, profiles, salt_plume, seaice, exf, ecco, ctrl :
213      add ECCO_OPTIONS.h, AUTODIFF_OPTIONS.h, CTRL_OPTIONS.h when needed
214      - ECCO_OPTIONS.h is needed when including ecco_cost.h, ecco.h
215      - AUTODIFF_OPTIONS.h is needed when including tamc.h, tamc_keys.h
216      - CTRL_OPTIONS.h is needed when including ctrl.h, optim.h, etc
217    o pkg/ctrl,ecco,exf :
218      - remove variables associated with NON-generic costs,
219        unless ECCO_CTRL_DEPRECATED is defined.
220      - remove NON-generic NON-obcs controls,
221        unless ECCO_CTRL_DEPRECATED is defined.
222    o pkg/ctrl : added ctrl_local_params.h
223    o pkg/ecco : added ecco_local_params.h
224    o verification : added ECCO_CTRL_DEPRECATED to most as and oad
225        experiments, which will progressively be removed once the
226        experiments are revised to use only generic controls/costs.
227    
228    checkpoint65f (2014/10/13)
229    o pkg/ctrl, ecco, seaice : minor changes in headers
230    o global_oce_llc90,cs32 : ecco_v4 verification exps now test generic
231        cost function and control capabilities added since checkpoint65c.
232    o pkg/ctrl: regroup all obcs ctrl variables in CTRL_OBCS.h.
233    o pkg/ecco: increase modularity and improve logic
234      - ecco_toolbox.F (new) : basic operations that are often used,
235        including ecco_zero, ecco_cp, ecco_cprsrl, ecco_diffmsk,
236        ecco_addcost, ecco_add, ecco_div, ecco_readbar.
237      - cost_gencal.F (new) : determine filnames and records.
238      - cost_genread.F, cost_generic.F : condense code using ecco_toolbox.
239      - cost_generic.F : use spzeroloc rather than hard-coded -9999,
240        and exploit the above functions leading to more compact code.
241      - cost_genread.F : rm un-necessary arguments, re-arrange args order.
242      - ecco_check.F, ecco_readparms.F : bring logic up to date (using_tpj,
243        using_ers, using_gfo, using_mdt is now only defined within gencost)
244    o pkg/ecco: extend generic cost capabilities
245      - pkg/ecco : added 3D gencost (ALLOW_GENCOST3D), added gencost
246        capabilities via gencost_preproc (+ _c,_i,_r related params),
247        gencost_posproc (+ _c,_i,_r related params), gencost_nrecperiod,
248        gencost_outputlevel arguments to cost_generic
249      - pkg/ecco/cost_genread.F (new) : interface between cost_generic
250        and active_read, making room for gencost_preproc to take effect.
251        Added preproc code ('climmon') to replace GENERIC_BAR_MONTH.
252      - pkg/ecco/cost_generic.F :
253        compute and store misfit maks*(model-data) in localdif that is
254        then used in cost and for output, output misfit if outlev.GT.0
255      - pkg/ecco/cost_averagesfields.F : depend on gencost_barskip
256        rather gencost_barfile for deciding whether to write barfile
257      - pkg/ecco/ecco_cost_driver.F : extract call to cost_profiles from cost_hyd
258      - pkg/ecco/ecco_cost_init_fixed.F : extract gencost weights from
259        ecco_cost_weights, re-activate ecco_summary, determine gencost_barskip
260      - pkg/ecco/ecco_summary.F : report gencost variables
261      - pkg/ecco/cost_gencost_customize.F : treat case of scatterometer costs
262    o pkg/sea/SEAICE_OPTIONS.h : add ALLOW_COST_ICE, ALLOW_SEAICE_COST_SMR_AREA
263    o pkg/ecco: internal re-organization
264      - resolve un-necessary dependancies within pkg/ecco and to pkg/ctrl
265        (rm includes of optim.h and ctrl.h, replace optimcycle with eccoiter,
266        mv relevant variables definition from ecco_cost.h to ecco.h,
267        make sure gencost routines only include ecco.h)
268      - throughout : add missing CCP switches, rm unused variables,
269        and rm un-necessary CPP switches
270      - throughout gencost routines : replace modelstartdate with
271        gencost_startdate when needed
272      - cost_bp_read.F : use arguments, instead of common blocs
273        so that it can be used also by (new) cost_gencost_bpv4.F
274      - ecco_init_varia.F : initialize RHOsumGlob_0, VOLsumGlob_0
275      - ecco_phys.F : compute etanFull
276      - ecco_readparms.F : rename using_topex as using_tpj, add
277        bpv4-grace to gencost list, initialize added parameters
278      - ecco_summary.F : include SIZE.h needed for augmented ecco.h
279    
280    checkpoint65e (2014/09/28)
281    o pkg/obcs:
282      - replaced the just-added CPP options with run-time variables
283        (see pkg/obcs/OBCS_PARAMS.h for details)
284    o pkg/obcs:
285      - add additional CPP options for sponge boundary layers
286        (see pkg/obcs/OBCS_OPTIONS.h for details)
287    o pkg/atm_phys:
288      - implement simple (obliquity only, assuming circular planet orbit)
289        seasonal cycle for incoming insolation ; used when run-time parameter
290        "select_incSW" is set to 1 ; by default (=0), uses old unchanged formula.
291    o pkg/exf, pkg/ecco, pkg/ctrl:
292      - add ctrlUseGen and .NOT.ctrlUseGen exclusive brackets
293      - activate gentim2d for xx_atemp,xx_aqh,xx_swdown,xx_lwdown,xx_precip

301      - add weight in CTRL_GET_GEN calls
302    o pkg/ctrl :
303      - ctrl_get_gen.F : add weight as input parameter, and apply
304        it directly rather than using smooth_correl2Dw (to be retired).

306    o pkg/ctrl :
307      - introduce run time switch ctrlUseGen (in ctrl.h, ctrl_check.F,
308        ctrl_init_variables.F, ctrl_readparms.F, ctrl_summary.F)
309      - re-activate ctrl_summary (call in ctrl_init.F)

343      - remove seaice_ctrl_map_ini (mv to ctrl_init_variables)
344    o ecco/ecco_ad_diff.list :
345      - add ecco_init_varia.f
346    o ecco/ecco_init_varia.F
347      - new routine
348    o pkg/streamice:
349      - move call to STREAMICE_INITIALIZE_PETSC from the_model_main.F
350        to streamice_init_fixed.F ; fix setting of STREAMICEisOn.
351      - from model/src, only call pkg/streamice routines if useStreamIce is TRUE.
352    o pkg/generic_advdiff:
353      - fix bug causing negatives in GAD_SMOLARKIEWICZ_HACK, introduced 8/8/2014.
354    o pkg/exf:
355      - exf_getffields.F : add xxg_atemp, xxg_aqh, xxg_swdown, xxg_lwdown,
356         xxg_precip capability
357      - exf_wind.F : no need for ALLOW_WSPEED_CONTROL cpp switch
358    o pkg/ctrl:
359      - ctrl_pack.F, ctrl_unpack.F : omit (un)packing of undefined xx_gentim2d
360    o model/src/load_fields_driver.F :
361      - move call to CTRL_MAP_GENTIM2D ahead of BULKF_FIELDS_LOAD, EXF_GETFORCING
362        so xx_gentim2d can be applied to e.g. exf fields in a timely manner.
363    o OpenAD verification experiments:
364      - Include explicitly AUTODIFF_OPTIONS.h, COST_OPTIONS.h, and CTRL_OPTIONS.h
365        in src files (to enable to skip the ECCO_CPPOPTIONS.h);
366        for now, only in pkgs used in OpenAD verification experiments.
367      - Change all except one (halfpipe_streamice) OpenAD experiments to use pkg
368        specific option file (AUTODIFF_OPTIONS.h, COST_OPTIONS.h & CTRL_OPTIONS.h)
369        instead of using ECCO_CPPOPTIONS.h (with all relevant options in it).
370        This applies to both TAF (*/code_ad/) and OpenAD (*/code_oad/) tests.
371    o OpenAD verification tests:
372      - finish removing ALLOW_AUTODIFF_OPENAD (replaced by ALLOW_OPENAD);
373      - finish replacing ALLOW_AUTODIFF_TAMC by ALLOW_AUTODIFF (except for
374        tape/storage which are specific to TAF/TAMC) in pkgs used in OpenAD exp.
375      - leave ALLOW_AUTODIFF_TAMC undef in OpenAD verification tests (*/code_oad/)
376        and remove local copy of "tamc.h" (needed only if ALLOW_AUTODIFF_TAMC).
377    o model/src & generic_advdiff:
378      - change hard-coded loop-range in S/R APPLY_FORCING_T/S to set T & S
379        forcing over 0:sNx+1, 0:sNy=1 (instead of just 1:sNx,1:sNy): Model
380        dynamics requires valid tracer forcing only over tile interior but, for
381        some diagnostics, may need to extend it over 1 point in tile halo region.
382      - in gad_calc_rhs.F, update calls to gmredi_x/ytransport to get valid
383        tendency over i,j_Min,Max range. This allows to simplfy i,j_Min,Max
384        setting in temp/salt/ptracer_integrate.F
385    o pkg/dic:
386      - multiply tracer tendencies by maskInC (if ussing OBCS) before updating
387        gchem tracers: this allows to skip the 2nd call to OBCS_APPLY_PTRACER
388        in gchem_forcing_sep.F
389    o pkg/autodiff & obcs:
390      - add storage of current OB values for U & V (was already done for T & S).
391    
392    checkpoint65c (2014/08/30)
393    o pkg/dic:
394      - take out of dic_atmos.F the initialisation part (corresponding to istate=0)
395        and move it to new S/R DIC_INI_ATMOS ; also simplify the dependencies for
396        AD compilers (but still a Pb with multi-threading and Ajoint dependencies).
397    o verification:
398      - new experiment testing OBCS and DIC pkgs, using params & output from
399        tutorial_global_oce_biogeo but limited to a sub-domain around Drake
400        passage: take OBCS from the last year of a 2 yrs simulation and initial
401        conditions from t=1.yr while keeping the same forcing.
402    o model/src:
403      - when allowFreezing=T, only reset below freezing initial Temp to Tfreezing
404        (at any k) if checkIniTemp is not set to FALSE (default checkIniTemp=T).
405    o pkg/diagnostics (Stats-Diags):
406      - re-write S/R DIAGSTATS_CALC (more similar to TARGET_NEC_SX part) to:
407        a) refine region where stats are computed, excluding where arrhFac=0 ;
408        b) fix missing interior mask (use with OBCS) in 3-D fields statistics;
409        c) extend regional stats over the region edges (for U or V pt location).
410    o pkg/gchem:
411      - add a (2nd) call to OBCS_APPLY_PTRACER in gchem_forcing_sep.F (needed since
412        pkg/dic is currently changing/updating ptracers values beyond the OB).
413    o verification (hs94):
414      - convert Held & Suarez external_forcing.F (from hs94.cs, with Sigma-coords
415        bits) to apply_forcing.F and undef USE_OLD_EXTERNAL_FORCING in experiments
416        hs94.cs-32x32x5 and tutorial_held_suarez_cs ; also use the same version of
417        apply_forcing.F in 2D hs94 (fwd, ad & oad) but keep LatLon hs94 unchanged.
418    o pkg/ptracers:
419      - implement Adams-Bashforth on pTracers (instead of on tracer tendency),
420        switched on by setting PTRACERS_doAB_onGpTr=F (default set to doAB_onGtGs)
421      - change exp4 secondary test (input.nlfs) to test AB on T & S & pTracer
422        with AB-2 code (so that it get tested).
423    o model/src:
424      - allow to apply Adams-Bashforth on Temp & Salt (instead of on gT,gS)
425        with AB-2 code (previously only available with AB-3 code).
426        Also move the code (call to ADAMS_BASHFORTH S/R) form thermodynamics.F
427        to temp/salt_integrate.F (since the 2nd part of gt/sNm1 update is done
428        there, by calling CYCLE_AB_TRACER).
429    o pkg/generic_advdiff:
430      - change Tracer argument (drop bi,bj indices) in S/R GAD_CALC_RHS,
431        GAD_C2_ADV_R, GAD_U3_ADV_R, GAD_C4_ADV_R, GAD_DIFF_R, GAD_BIHARM_R
432        + also in GMREDI_X/Y/RTRANSPORT ; and update corresponding calls in
433        S/R temp/salt/ptracers_integrate.F
434    o model/src & pkg/ptracers:
435      - remove common block variables gT,gS (in DYNVARS.h), except when
436         USE_OLD_EXTERNAL_FORCING is defined; update TAF storage accordingly.
437      - remove common block variable gPtr.
438    o model/src & pkgs:
439      - change gTracer (and/or tracer) argument (drop bi,bj indices) in S/R
440         ADAMS_BASHFORTH(2&3), CYCLE_(AB_)TRACER, FREESURF_RESCALE_G,
441         IMPLDIFF, SOLVE_TRIDIAGONAL & _PENTADIAGONAL, GAD_SOM_ADVECT,
442         GAD_ADVECTION, GAD_CALC_RHS, GAD_IMPLICIT_R, TIMEAVE_CUMUL_DIF_1T
443      + change accordingly all calling S/R.
444      - use local temperature/salinity/ptracer tendency array (without bi,bj)
445        in S/R temp/salt/ptracers_integrate.F
446    o pkg/seaice:
447      - move computation of stress contributions to rhsU/V in s/r seaice_lsr
448        to separate s/r seaice_lsr_rhsu/v in order to be able to re-use code
449      - make u/vIceC local variables if SEAICE_CGRID is defined only to be used
450        in seaice_lsr
451      - seaice_lsr.F: make local 4D arrays UXX, VYY, etc 2D
452        in s/r seaice_lsr_calc_coeffs
453    o pkg/mdsio:
454      - in MDS_READ/WRITE_FIELD, stop if file-name (+prefix) is too long
455        (e.g., > MAX_LEN_MBUF -90 ) or, in INI_MODEL_IO, if mdsioLocalDir is
456        too long (e.g., > MAX_LEN_FNAM/2 )
457    
458    checkpoint65b (2014/08/12)
459    o pkg/matrix:
460      - pass, as argument, updated tracer field to S/R MATRIX_STORE_TENDENCY_EXP
461    o model/src:
462      - fix initialisation of geothermalFile; compile geothermal-flux code in
463        natl_box verification experiment.
464    o model/src & pkg/down_slope:
465      - push the k loop inside S/R TIMESTEP_TRACER (now called outside the k loop).
466      - in dwnslp_apply.F, update tracer tendency instead of the future tracer
467        field and call S/R DWNSLP_APPLY before TIMESTEP_TRACER; this affects
468        results at machine truncation level: update output of experiments
469        global_ocean.90x40x15.dwnslp (FWD) and lab_sea.noseaicedyn (AD).
470    o pkg/diagnostics (Stats-Diags):
471      - do not cumulate the full volume when DIAGNOSTICS_FILL is
472        called with bibjFlg < 0 (no increment of the counter for 2D/3D diag);
473        This fix the mean statistics when DIAGNOSTICS_FILL is called multiple
474        times (but Min,Max and StD are still wrong).
475    o model/src:
476      - add geothermal flux forcing: read in ini_forcing.F as time-constant
477        field "geothermalFlux" applied in S/R APPLY_FORCING_T (apply_forcing.F)
478    o model/src:
479      - move CYCLE_TRACER calls from tracers_correction_step.F to temp/salt/ptracer
480        _integrate.F so that, when leaving S/R THERMODYANMICS, theta,salt and pTrac
481        arrays are already updated while adjustments (filters, conv.adjustment) are
482        still applied later, in S/R TRACERS_CORRECTION_STEP.
483    o model/src:
484      - store in common bloc array "rhoInSitu" the virtual potential temperature
485        anomaly that is used to compute geopotential: this make the atmos code
486        more similar to ocean code which already uses rhoInSitu in calc_phi_hyd.F
487    o pkg/seaice/seaice_lsr.F
488      - rename integer variable ilcall to ipass (that's what it is called
489        in the residual diagnostics
490      - change time stepping for NPSEUDOTIMESTEP > 2 (does not change the
491        default) for improved non-linear convergence of the first few steps
492      - adjust a few comments and add new ones to explain some of the store
493        directives
494    o pkg/generic_advdiff (& ptracers):
495      - re-work the code to check for valid advection scheme and for minimum
496        size of overlap (now stored in local common bloc in gad_advscheme.F)
497    o pkg/seaice: another attempt to make the adjoint work for sea ice dynamics
498      - re-initialize more variables in seaice_lsr: u/vIceC, u/vIceNm1
499      - add an auxilliary variable "bet" and fix store directives and keys in
500        seaice_lsr_tridiagu/v, this seems to do the trick (i.e. more or
501        less exact gradients in my tests); but there are still
502        recomputation warning (although gradients are sort of OK), when
503        SEAICE_LSR_VECTORIZE is not defined, so this flag and
504        SEAICE_LSR_VECTORIZE_ZEBRA are recommended for efficiency.
505      - update verification experiments lab_sea.
506      - change some comments in S/R seaice_calc_viscosities
507    o model/src:
508      - if staggerTimeStep=T, always apply exchange to velocity field in
509        do_stagger_fields_exchanges.F instead of in do_fields_blocking_exchanges.F
510        (independent of using multi-dim advection or not); no effect on FWD run
511        but affects AD results (at machine truncation level): update output of
512        experiment 1D_ocean_ice_column (ad: 12 digits), hs94.1x64x5 (ad,oad: 13.d)
513        and isomip (oad: 12.d).
514    o pkg/generic_advdiff:
515      - stop if doAB_onGtGs is set to FALSE but ignored
516      - refine warning related to stability of tracer time-stepping
517        regarding internal wave dynamics.
518      - setting of AdamsBashforth_T,S when doAB_onGtGs=F: remove condition
519        on staggerTimeStep & implicitIntGravWave (will now get a warning
520        if potentially unstable).
521    o pkg/kl10:
522      - add new pkg "kl10" for mixing due to internal wave breaking, from
523        http://www.sciencedirect.com/science/article/pii/S1463500310000144
524        (contribution from Jody Klymak), tested in verification experiment
525        verification/internal_wave/input.kl10/
526    o isomip experiment:
527      - test pkg/shelfice with Non-Lin Free-Surf in one of the FWD set-up
528        (input.htd) and update the output.
529    o cd_code experiments:
530      - use default cd_code options (#undef CD_CODE_NO_AB_MOMENTUM &
531        #undef CD_CODE_NO_AB_CORIOLIS) in experiments: cfc_example (fwd)
532        global_ocean.90x40x15 (ad & oad) and OpenAD (ad & oad) and
533        update the corresponding output.
534    o pkg/seaice:
535      - reduce the number of include files and store directives in
536        S/R seaice_lsr_tridiagu/v
537      - change the order of loops in one case in S/R seaice_lsr_tridiagv
538        (only for SEAICE_VECTORIZE_LSR_ZEBRA defined), which allows me to
539        get rid off one store directive (a TAF bug?)
540      - add one more instance of ifdef SEAICE_VECTORIZE_LSR_ZEBRA in
541        S/R seaice_lsr_tridiagv to change the loop range for consistency
542      - remove ilcall, m from parameter list of S/R seaice_lsr_tridiagu/v
543      - fix a bug that affects the JFNK solver: replace sNx/y by i/jMax in
544        S/R seaice_lsr_tridiagu/v (requires update of
545        offline_exf_seaice/input.dyn_jfnk)
546    
547    checkpoint65a (2014/07/27)
548    o model/src:
549      - Non-Lin Free-Surf in p/z coords: allows hFacW,S to be larger than
550        surrounding hFacC=1 @ edge of a step with different kSurfC on either side
551        (topo in p-coords, ice-shelf in z-coords); update output of experiments
552        tutorial_global_oce_in_p and isomip (both AD and OpenAD output).
553    o model/src:
554      - collect momentum forcing tendency into local 2-D array (passed as argument
555        to apply_forcing S/R); this simplifies mom. Forcing diagnostics and CD_CODE
556        parts in timestep.F (without CD_CODE_NO_AB_MOMENTUM defined = the default);
557        affects results at machine truncation level (e.g., if using OBCS_SPONGE).
558      - collect T & S forcing tendency into local 2-D array (passed as argument to
559        apply_forcing S/R); add 3-D diagnostics for temp & salt forcing tendency.
560        affects results at machine truncation level (e.g., ocean: if using
561        SHORTWAVE_HEATING ; atmos: if using FrictionHeating or (atm_Rq<>0) moist
562        correction due to vertical advection).
563      - update output of experiments: fizhi-cs-32x32x40 (13 digits),
564        global_ocean.cs32x15 (fwd: icedyn, seaice, thsice, all 3 @ 11d; adm & tml:
565        seaice_dynmix & thsice, fwd grd @ 3 & 8), hs94.1x64x5 (ad grd @ 13),
566        obcs_ctrl (ad & fwd grd @ 12 & 7).
567    o pkg/ptracers & diagnostics:
568      - use ptracers (short) name (instead of long one) to make ptracers diagnostics
569        title (to avoid some unexpected truncation); sort out ptracers diags units.
570      - collect ptracer forcing tendency into local 2-D array (passed as argument
571        to apply_forcing S/R); add 3-D diagnostics for ptracers forcing tendency.
572    
573    checkpoint65 (2014/07/18)
574    o pkg/fizhi:
575      - add parenthesis around fizhi tendencies in fizhi_tendency_apply.F: this
576        affects results at machine truncation level. Update output of experiments
577        fizhi-cs-32x32x40 (12 digits for cg2d) & fizhi-cs-aqualev20 (13 digits).
578    o pkg/seaice: more clean up
579      - rename TAF common block tapes to be more consistent and remove
580        unnecessary duplicates
581      - add store directives to remove more recomputations, but use smaller
582        tapes (and adjust keys) when SEAICE_LSR_ADJOINT_ITER is undefined.
583        The idea behind this flag is to reduce the memory footprint when the
584        adjoint of the LSR is not required. As of now, defining the flag
585        SEAICE_LSR_ADJOINT_ITER increases 4 common block tapes for 2D field by
586        a factor of SOLV_MAX_FIXED (=500 by default in SEAICE_SIZE.h).
587        For experiment offline_exf_seaice, this means on a linux box with gfortran
588        nearly a factor of 10 (but keep in mind there is mostly seaice code in
589        this experiment):
590        > size mitgcmuv_ad
591        text    data        bss     dec        hex
592        5100659 1216  220458952  225560827  d71c8fb
593        5339425 1200 1868783272 1874123897 6fb4dc79 (SEAICE_LSR_ADJOINT_ITER)
594        but only a moderate increase of 36% for global_ocean.cs32x15:
595        text    data        bss     dec        hex
596        6695027 1648 1014578664 1021275339 3cdf6ccb
597        6695203 1648 1382505320 1389202171 52cd8afb (SEAICE_LSR_ADJOINT_ITER)
598      - note: there are still recomputations in global_ocean.cs32x15 and
599        offline_exf_seaice and the gradient agreement changes (gets a
600        little worse) for global_ocean.cs32x15 (-> update output_adm.seaice.txt)
601      - in general, the AD gradients still are wrong
602    o OpenAD
603      - clean up code_oad/ directories somewhat by moving files
604        dontCompile, dontTransform, keepOriginal to OAD_support/
605    o model/src:
606      - using MOM fluxform and Non-Lin Free-Surf with momDissip_In_AB=F
607        (not currently tested): add dissipation terms before NLFS rescaling of
608        tendencies (previously done after).
609    o pkg/diagnostics:
610      - write stats-diags in ascii file with more digits (same as in monitor).
611    o pkg/down_slope:
612      - drop the bi,bj dimension of argument recip_hFac in S/R DWNSLP_APPLY; with
613        NLFS (not tested), use new recip_hFac value in order to conserve tracer.
614    o model/src:
615      - new file "apply_forcing.F" containing all the code previously in
616        external_forcing.F, but with new argument list: pass, as new argument,
617        the current level tendency array to update (instead of a direct update
618        of the common bloc array). Change the corresponding calls.
619      - add CPP option USE_OLD_EXTERNAL_FORCING (default is undef) to use
620        EXTERNAL_FORCING_U,V,T,S subroutines (for backward compatibility).
621    o pkg/seaice/seaice_lsr, a little bit of clean up
622      - rearrange some code blocks, so that now all calculations for
623        setting up the right-hand-sides done within one single block
624        (I find that easier to read and understand)
625      - rearrange freedrift-code to reduce the number of ifdefs
626      - adjust some indentations and comments
627    
628    checkpoint64z (2014/07/10)
629    o model/src and several pkgs:
630      - change argument list of all S/R called from external_forcing.F and
631        called from ptracers_forcing.F (renamed to ptracers_apply_forcing.F)
632        to pass, as argument, the current level tendency array to update
633        (instead of a direct update of the common bloc array).
634      - change also (in the same way) argument list of PTRACERS_APPLY_FORCING;
635      - rename taueddy_external_forcing.f to taueddy_tendency_apply.F
636    o pkg/seaice/seaice_lsr.F
637      - always initialize local arrays in seaice_lsr_tridiagu/v
638      - add more local tapes to seaice_lsr_tridiagu/v
639      - move storing u/vice(:,:,bi,bj) out of seaice_lsr_tridiagu/v, but
640        keep it in bi/bj loop; this seems to be essential
641      - gradients are still wrong but only by 4-7 orders of magnitude
642        instead of 15 orders of magnitude, lab_sea improves a little
643    o pkg/seaice
644      - (pkg/autodiff) remove storing/restoring of seaiceMaskU/V that
645        generates unnecessary code in seaice_lsr_ad
646      - add more store directives in seaice_lsr to avoid unnecessary code
647        in seaice_lsr_ad
648      - exclude some residual computations in seaice_lsr when
649        ALLOW_AUTODIFF_TAMC is defined in order to avoid unnecessary code
650        in seaice_lsr_ad
651      - add more storing, a new tape (model/src/the_main_loop.F) and
652        another key for SEAICE_LSR_VECTORIZE_ZEBRA (the local keys ilockey
653        and klockey should be checked by a specialist)
654      - modify ( define SEAICE_VECTORIZE_LSR and SEAICE_LSR_ADJOINT_ITER )
655        and update lab_sea after previous changes in pkg/seaice below
656    o pkg/autodiff:
657      - introduce useSmoothCorrel2DinAdMode, SEAICEapproxLevInAd, and
658        viscFacInAd : run time parameters allowing for adjoint switches
659        note : logic for useSmoothCorrel2DinAdMode is in ctrl_readparms.F
660    o pkg/ecco:
661      - introduce cost_gencost_boxmean.F that computes a box mean
662        temperature (for use in adjoint sensitivity studies).
663    o model/src/set_defaults.F : initialize viscFacAdj to 1.
664    o pkg/mom_common/mom_calc_visc.F:
665      - ifdef ALLOW_AUTODIFF then include viscFacAdj factor.
666    o pkg/seaice/seaice_summary.F:
667      - statement for SEAICEadjMODE now in autodiff_readparms.F
668    o pkg/seaice:
669      - remove some store directives and add new ones in an effort to get
670        finally rid off the recomputation warnings. This is successful
671        when SEAICE_VECTORIZE_LSR ***and*** SEAICE_LSR_ADJOINT_ITER are
672        defined (i.e. no extensive recomputation warnings left), but there
673        are still too many recomputations on the solver iteration level
674      - define SEAICE_VECTORISZE_LSR in offline_exf_seaice/code_ad/SEAICE_OPTIONS.h
675      - move definition of MPSEUDOTIMESTEPS into TAMC-block in
676        SEAICE_SIZE.h
677      - add a store directive in S/R seaice_calc_viscosities
678    o pkg/seaice (ITD code):
679      - fix definition of Hlimit for multi-threaded case
680      - use double precision arithmetic to compute Hlimit: this affects results;
681        update output of experiment seaice_itd.
682    o replace content of verification/seaice_itd
683      - instead of a 1D column use the configuration of offline_exf_seaice
684        to test the ice thickness distribution code with ridging
685      - this is a first shot at this experiment
686      - change of some defaults of ridging parameters SEAICEhStar (from
687        100 to 25) and SEAICEmuRidging (from 5 to 3) in seaice_readparms.F
688        and lot of new comments.
689    
690    checkpoint64y (2014/06/20)
691    o pkg/seaice/seaice_reg_ridge.F:
692      - modify the regularization of very small volumes of ice; only check
693        total volume HEFF, and do not apply correction to individual ice
694        classes because that leads to funny patterns in the heat and fw-fluxes
695        into the ocean. Adjust seaice_itd/results/output.txt
696      - replace nITD by SEAICE_multDim in loop-ranges
697    o pkg/exf:
698      - add code to process the case field period = -12. with UV interpolation.
699      - move debug print (formerly active when exf_verbose=T) from EXF_getFFieldRec
700        into S/R that calls it (i.e., exf_set_gen.F, exf_set_uv.F & obcs_exf_load.F)
701    o verification/global_with_exf:
702      - switch all fields period to -12. (was previously untested) in input/data.exf
703        (but keep secondary test ".yearly" unchanged); update the reference output.
704    o pkg/cal:
705      - new calendar type "noLeapYear" for 365 days calendar without any leap year.
706    o pkg/exf:
707      - new integer parameter "exf_debugLev" (default set to main model debugLevel)
708        to replace logical switch "exf_verbose"
709      - report in STDOUT when loading a new record (if exf_debugLev >= 3)
710    o pkg/sbo:
711      - update from Katherine Quinn: evaluate mass directly from density and SSH
712        (budget using Finite Volume method) instead of from bottom pressure.
713      - allow testreport to collect few selected SBO output ; tested in exp.
714        global_ocean.90x40x15 (after updating the results, to include SBO output).
715      - fix some multi-threading issues (in output part).
716    o model/src & most packages:
717      - always call {PKG}_READPARMS even if corresponding use{PKG}=F;
718      - in {PKG}_READPARMS, in case use{PKG}=F: add a call to new S/R
719        PACKAGES_UNUSED_MSG to print a weak warning when parameter file
720        "data.{pkg}" exist ; and leave the S/R (return) just after.
721      - more standard LAND pkg interface (land_init_fixed.F, land_check.F).
722        + call LAND_READPARMS from packages_readparms.F
723    o pkg/seaice:
724      - remove code that resets useThSice in S/R seaice_readparms and
725        replace it by a warning in S/R seaice_check
726      - remove parameter MULTDIM, replace with nITD and runtime
727        parameter SEAICE_multDim (still hard-wired to nITD if
728        SEAICE_ITD is defined)
729    
730    checkpoint64x (2014/05/24)
731    o verification/lab_sea:
732      - update adjoint and TLM output following changes to pkg/salt_plume
733      - un-do the update after putting back local recip_Cp in few places.
734    o pkg/salt_plume: modifications by An Nguyen:
735      - add capability to do brine rejection (salt-plume) as function of
736        volume+tracers (instead of only salinity tracer).
737      - conserve volume by exchanging volume from each kLev to above to
738        accommodate in-coming brine volume
739      - store surface and klev exchanged fraction + volume in 4 new 3-d arrays
740      - switch KPP surf buoyancy due to brine forcing to 3-d
741        (3 more 3-d arrays, 2 for SPforcing[T,S], 1 for boplume)
742      - add salt_plume_volfrac, salt_plume_apply, salt_plume_tendency_apply_t
743      - unrelatedly, also add ad-hoc capability to vary salt_plume scheme
744        in East/West Arctic.
745    o pkg/sbo:
746      - incorporate modifications from Katherine Quinn to enable the use of sbo
747        pkg in ECCO-v4 set-up ; remove SBO-TimeAve output ; add monitor-like
748        output for future testreport verification (unfinished).
749    o pkg/atm_phys:
750      - change diagnostics (AtPh_Trf & AtPh_Qrf) of DARGAN_BETTSMILLER S/R:
751        skip the reseting of t_ref & q_ref to initial t & q ; this preserve the
752        output of S/R CAPECALCNEW (Parcel temp & q) for diagnostics.
753    o pkg/seaice
754      seaice_calc_ice_strength.F: modify expression to avoid divisions
755        (affects truncation)
756      seaice_do_ridging.F: clean up the insectarium
757      - fix a bug that was compensated by areaScaling (-> remove areaScaling code)
758      - added SEAICEsnowFracRidge to redistributed snow (2nd bug)
759      - set closing/openingRate to zero where no extra iteration is need (3rd bug)
760      - add some debugging information and error messages (warnings)
761    o model/src: modifications relatd to atmosphere p*:
762      - Switch to more accurate p* coordinate slope term (calc_grad_phi_hyd.F)
763      - With p* or Sigma-P, use constant reference Pot.Temp (thetaConst) instead
764        of vertical profile tRef in geopotential background and anomaly.
765      - Acount for true p* correction in theta <-> T conversion in pkg/aim_v23
766        and pkg/atm_phys.
767      - Update FWD output of experiments: aim.5l_cs (x2), fizhi-cs-32x32x40,
768        fizhi-cs-aqualev20, fizhi-gridalt-hs, tutorial_held_suarez_cs, cpl_aim+ocn.
769    o pkg/seaice: fix a bug in seaice_prepare_ridging.F, forgot a sqrt
770    o pkg/ptracers: compute ptracer source/sink due to linear free surface.
771        not used right now, but can be used in BGC packages to fix conservation.
772    o pkg/dic, pkg/gchem: move tracer_meanarea to gchem, so it can be used by
773        other packages too.
774    o pkg/seaice/seaice_calc_ice_strength.F: replace SEAICE_rhoSnow by
775        SEAICE_rhoIce in the Rothrock (1975)-type strength calculations (bug fix)
776    o model/src:
777      - since we have several heat capacity (even in model/src), define "recip_Cp"
778        as local variable (no longer in common block) to avoid any confusion.
779      - add thetaConst in PARAMS.h (to be used with pStar or sigma-P coords).
780    o pkg/exf:
781      - from Jeff Scott: add option (#define EXF_CALC_ATMRHO) to calculate local
782        air density as function of air Temp, Humidity and atm pressure.
783    
784    checkpoint64w (2014/05/02)
785    o verification:
786      - update output_adm.txt files for experiment global_ocean.cs32x15 (seaice &
787        seaice_dynmix) and lab_sea (primary test & noseaicedyn): moving/changing
788        code from seaice_growth.F & seaice_advdiff.F to new ridging routines
789        seaice_reg_ridge.F seaice_do_ridging.F affects AD gradient
790        (down to 8-7 matching digits for global_ocean and 5-6 for lab_sea).
791    o model/src: for atmosphere in p* coords:
792      - store factor rStarFacC**atm_kappa (= pStarFacK) in common block
793      - implement more accurate p* coordinate slope term (in calc_grad_phi_hyd.F),
794        but not yet activated.
795    o pkg/seaice: fix restart problem for ITD with new ice strength parameterisation:
796      - move computation of opnWtrFrac = 1-AREA to before computing ice strength
797      - this changes the results (but not for any verification experiment, because
798        none tests this), but avoids having an extra field in the restart files
799    o pkg/seaice: remove global variable TICE (not needed)
800      - replace by TICES or local variable where necessary (cost_seaice_test,
801        seaice_diagnostics_state)
802      - move copying TICE to TICES from seaice_check_pickup to seaice_read_pickup
803      - use specific read/write routines for reading and writing individual leves
804        of a multilevel field
805    o pkg/ctrl & model/inc:
806      - move additional anomaly fields of control vars (related to options:
807         ALLOW_KAPGM_CONTROL, ALLOW_KAPREDI_CONTROL and ALLOW_BOTTOMDRAG_CONTROL)
808        from DYNVARS.h into new header file: CTRL_FIELDS.h
809    o pkg/seaice: some small modifications to the ridging code
810      - make fw2ObyRidge a global variable and add the freshwater flux to
811        seaice_growth
812      - pass actual thickness from seaice_prepare_ridging, so that it is
813        computed only in one place and compute it in the same way as in
814        seaice_growth
815      - initialise more fields in seaice_do_ridging that where cause floating
816        point exceptions over land
817    o pkg/seaice: preparations for ridging code and first real ridging code
818      - move most of "PART 1" of S/R seaice_growth into a new and separate
819        S/R seaice_reg_ridge that will both regularize the state variable after
820        advection call the actual ridging routine;
821      - requires to make 5 fields global fields: d_HEFFbyNEG,d_HSNWbyNEG,
822        d_AREAbyRLX,d_HEFFbyRLX,saltFluxAdjust;
823      - remove ridging code from seaice_advdiff
824      - clean up remaining part 1 of seaice_growth in an attempt to make it
825        more readable (this is probably subjective)
826      - call seaice_itd_redist once in the initialisation phase to have the initial
827        conditions in the correct category
828      - finally: add new ridging routine for ITD code
829    
830    checkpoint64v (2014/04/11)
831    o pkg/ecco:
832      - add runtime parameters mdt[start,end]date[1,2]
833      - rename variable "tpmean" as "mdt" and "topexmeanfile" as "mdtdatfile"
834    o pkg/seaice:
835      - make deltaC a global variable, so that it can be used in ridging code
836      - first step towards ridging: introduce new routines that compute
837        ice strength based on ridging parameters
838      - add diagnostic for HSNOWITD
839      - add opnWtrFrac as a global variable (required for ridging scheme)
840    o pkg/salt_plume + pkg/seaice/seaice_growth.F
841      - add SALT_PLUME_IN_LEADS flag to activate pkg/salt_plume only when ice
842        AREA exceeds a threshold (code contributed by I.Fenty in 2011)
843    o verification/hs94.1x64x5:
844      - leave ALLOW_AUTODIFF_TAMC undefined in code_oad/AUTODIFF_OPTIONS.h
845      - do not use ECCO_CPPOPTIONS.h anymore for TAF & OpenAD Adjoint tests.
846    o autodiff:
847      - Start to include explicitly AUTODIFF_OPTIONS.h, COST_OPTIONS.h,
848        and CTRL_OPTIONS.h in src files (to enable to skip the ECCO_CPPOPTIONS.h)
849        For now, only in pkgs used in verification/hs94.1x64x5.
850      - Replace ALLOW_AUTODIFF_TAMC by ALLOW_AUTODIFF (except for tape/storage
851        which are specific to TAF/TAMC).
852      - Replace ALLOW_AUTODIFF_OPENAD by ALLOW_OPENAD:
853        since ALLOW_OPENAD is defined in PACKAGES_CONFIG.h (any time pkg/openad
854        is compiled), this simplifies/reduces which *_OPTIONS.h file to include.
855      - OpenAD: change Makefile to generate the appropriate AD_CONFIG.h when
856        building mitgcmuv_ad (make adAll).
857    o pkg/ecco:
858      - cost_gencost_seaicev4.F:
859         reformulate proxy cost as function of sst and local param SEAICE_freeze
860         change cost names from siv4-[sst,vol] to siv4-[deconc,exconc]
861      - add stop statement if old names siv4-[sst,vol] are used
862      - add snapshots + cost reports for atmospheric longwave
863      - remove factor 0.1 in front of wtau[u,v]
864      - replace never used flag ALLOW_TMI_COST_CONTRIBUTION with
865         ALLOW_TMI_SST_COST_CONTRIBUTION
866    o pkg/atm_phys:
867      - add some diagnostics for Short-wave and for convection S/R.
868    o pkg/seaice/seaice_growth:
869      - fix a bug in the lateral melt parameterization for SEAICE_ITD
870        in seaice_growth; tempFrz needs to be computed inside the i/j-loop
871      - rearrange loop order for better vector code in the same code block
872      - rewrite the floeDiameter formula to have fewer divisions
873      -  (miraculously) none of this changes the results of seaice_itd
874    o pkg/smooth:
875      - move param smooth2Ddiffnbt to pkg/ecco
876    o pkg/salt_plume:
877      - salt_plume_frac.F:
878         clean up local param names
879         reformulate (1-frac) to frac; original 1-frac was based on swfrac code
880    o pkg/rw:
881      - add RS version of S/R READ_MFLDS_LEV.
882    o pkg/streamice:
883      - fix the restart test by writing/reading pickup_streamice files.
884    o pkg/seaice:
885      - refine checks for jfnk-related parameters
886      - comment out if statement with SEAICEuseIMEX parameter as long as there
887        is no IMEX code to avoid confusion and surprises
888    
889    checkpoint64u (2014/03/07)
890    o verification/MLAdjust:
891      - rename secondary test suffix:
892         1.leith  -> A4FlxF  + switch to flux-form & add side-drag
893         0.leithD -> AhFlxF  + switch to flux-form
894         0.smag   -> AhVrDv  (use Vorticity-Div. visc form) + add side-drag
895         0.leith  -> AhStTn  (use Strain-Tension visc form) + add side-drag
896    o pkg/mom_vecinv:
897      - remove unused arguments from S/R MOM_VI_HDISSIP & MOM_HDISSIP (as it used
898        to be before mom_calc_visc.F)
899      - skip the call to MOM_CALC_TENSION & MOM_CALC_STRAIN if not needed.
900      - add 2nd copy of vort3 & strain that knows about lateral BC (free/no slip):
901        this is simpler for the adjoint and for diagnostics.
902    o model/src + pkg/momentum:
903      - add input files for  2-D additional Western and Southern cell-edge wall
904         (e.g., to add "thin-wall" where it is =1).
905      - fix sideDrag option for thin-walls with Non-Lin Free-Surf
906        using 2nd hFacZ that is computed from initial (fix domain) hFac
907      - known limitations of thin wall implementation: not yet coded for sigma
908        coords; not working with CD-scheme neither.
909    o pkg/seaice:
910      - rename recently introduced parameters from (wrong name) AB to
911        BDF (backward difference time discretisation)
912      - retire runtime parameters SEAICEuseAB2, SEAICE_abEps
913    o tools/adjoint_options:
914      - remove setting of "OPENAD=true" (now set by command line "genmake2 -oad")
915    
916    checkpoint64t (2014/02/01)
917    o pkg/ecco
918      - add compile flag ALLOW_GENCOST_TIMEVARY_WEIGHT in ECCO_OPTIONS.h and
919        runtime logical flag gencost_timevaryweight to read daily sea-ice sigma
920      - replace hard-coded record number and period which only work for monthly
921        with read-in runtime param that works for other periods (month,day,year)
922    o pkg/thsice
923      - corrected store directive fixes thsice adjoint gradient checks
924    o genmake2 & testreport:
925      - add genmake2 option "-oad" to generate a Makefile for OpenAD built and
926        in this case, use tools/adjoint_options/adjoint_oad as default AD optfile.
927        Update testreport accordingly. No need to set "export OPENAD=true"
928        in adjoint_options/adjoint_oad anymore (will be removed later).
929    o pkg/shelfice:
930      - put T & S shelfice forcing into model surfaceForcing_T,_S (for now,
931        only if SHELFICEboundaryLayer=F); Change model/src/external_forcing.F
932        so that surface forcing applies to k=kSurf if using pkg/shelfice.
933    o pkg/ctrl, pkg/grdchk, pkg/ecco:
934      - Changes to make GENARR more modular (i.e. invisible if not used)
935    o model/src/temp_integrate.F and salt_integrate.F
936      - re-include store directives that were removed on Dec 27th.
937    o model/src/external_forcing_surf.F
938      - add storage directives for EmPmR and PmEpR to avoid recomputation of
939        seaice_model in the adjoint that is problematic when seaice_model is
940        turned off in the adjoint. The resolved issue dated back to July when
941        EXTERNAL_FORCING_SURF call was moved.
942        Update global_ocean.cs32x15/*/output_adm.seaice_dynmix.txt accordingly.
943    o pkg/exf/exf_check.F
944      - fix a small bug again (originally found by Wentao Liu, now found again)
945      - streamline error output
946    o pkg/streamice and aim_v23:
947      - replace a few "_EXCH_XY_RL (" with "_EXCH_XY_RL(", so that
948        Apple's /usr/bin/cpp knows what to do:
949        Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)
950        Target: x86_64-apple-darwin13.0.0
951    
952    checkpoint64s (2014/01/05)
953    o tools/adjoint_options:
954      - switch to fastopt.net TAF server (instead of default fastopt.de) for
955        AD optfiles adjoint_diva & adjoint_f95 (similar to adjoint_default).
956    o model/src:
957      - remove some unnecessary TAF storage directives in forward_step.F and
958        in dynamics.F (note: not always removed by TAF, e.g., double storage
959        of kappaRU,kappaRV in former version of dynamics.F).
960    o model/src & pkg/ptracers:
961      - call directly GAD_IMPLICIT_R & IMPLDIFF + DWNSLP_APPLY from temp_integrate.F
962        salt_integrate.F and ptracers_integrate.F (instead of from thermodynamics.F)
963        and remove ptracers_dwnslp_apply.F & ptracers_implicit.F
964      - call MATRIX_STORE_TENDENCY_EXP for each tracer (in ptracers_integrate.F)
965      - add fZon & fMer as output argument of S/R GAD_CALC_RHS.
966      - update TAF AD-output of experiments global_ocean.90x40x15 (13 for AD-grad).
967    o useSingleCpuInput separates single-CPU input from single-CPU output;
968        for now only implemented for in exf_interp_read.F
969    o verification/advect_xy:
970      - fix missing EXCH call in local version of ini_salt.F and update output.
971    o momentum diagnostics:
972      - fix which deltaT is used in Total-Tendency diagnostics.
973      - fix typo in diagnostics for momentum tendency from AB.
974    o pkg/seaice/seaice_lsr.F: fix an initialisation bug for the
975        SEAICE_VECTORIZE_LSR_ZEBRA option that lead to NaNs on a NEC-SX8
976    
977    checkpoint64r (2013/12/08)
978    o verification/*/results:
979      - Update reference output of experiments that were passing with just 13 digits
980         (make it easier to detect future changes in results)
981    o model/src & pkg/ptracers:
982      - move calls to GAD_ADVECTION (Multi-Dim advection) from thermodynamics.F to
983        inside temp_integrate.F and salt_integrate.F and from ptracers_advection.F
984        to inside ptracers_integrate.F ; remove ptracers_advection.F
985    o coupling interface pkgs:
986        [atm_compon_interf, ocn_compon_interf & atm_ocn_coupler]
987      - change the config check to test the agreement of Ocean Depth
988        with ATM land/sea mask (instead of ATM orography);
989      - send to coupler the number of coupler time-steps to do for this run:
990        this allows to check for consistency and don't need anymore to be
991        specified in parameter file "data";
992      in coupler:
993      - check consistency of RunOff map versus Ocean Depth and ATM land/sea mask.
994      - improve report to log-file of config setting (pass log-file unit to few S/R)
995    o pkg/compon_communic:
996      - add coupling send/receive for non-tiled integer vector;
997      - add S/R to check and stop if any proc has an error (similar to
998        eesupp/src/stop_if_error.F but single thread and across Comm_World).
999    o pkg/exch2:
1000      - in exch2*_get_rx[1,2]: use new list "W2_tileIndex" to replace search
1001        through list of all tiles my proc owns.
1002    o model/src:
1003      - AUTODIFF only: in calc_adv_flow.F, recompute rTransKp (instead of copying
1004        from rTrans) to simplify dependencies (no need to store rTrans anymore in
1005        calling S/R); this affects AD results at machine truncation level:
1006        update AD-output (TAF) of experiments: 1D_ocean_ice_column,
1007        bottom_ctrl_5x5 & obcs_ctrl (12 digits for AD grad, same FWD grad).
1008    o tools/build_options:
1009      - simplify Warnings options (-ieee & -devel cases) in linux_amd64_gfortran
1010    o coupling interface pkgs:
1011        [compon_communic, atm_compon_interf & ocn_compon_interf]
1012      - move declaration of local array "ibuf" out of header file "CPLR_SIG.h"
1013        to each S/R that needs it; remove un-used variables.
1014      - change component tile registration (cpl_register.F in both compon_interf
1015        and mitcomponent_tile_register.F) to pass the full list of tiles
1016        information (including bi,bj) in 1 vector (instead of in a bi,bj matrix).
1017      - with pkg/exch2: adopt the same convention used for I/O to define mapping
1018        towards coupler global array (unless W2_useE2ioLayOut=F):
1019         a) can now use different tiling between atm & ocn comp.
1020         b) no needs to modify the run-Off map when changing tiling (was needed
1021            even if using the same tiling between atm & ocn).
1022         c) will allow to run with blank-tiles in 1 component (e.g., for ocean
1023            full land tiles); not yet tested.
1024      - check for valid mapping from comp. tile to coupler global array
1025      - improve report of tile registration results to log file.
1026    o pkg/exch2:
1027      - in eesupp/src/eeboot.F: move call to W2_EEBOOT before Coupler
1028        tile-registration (CPL_REGISTER);
1029      - activate (un-comment) definition and setting of "W2_tileIndex" list to
1030        store the local bi,bj indices of each tile;
1031      - also print bi,bj in local report to log file;
1032      - fix pkg/debug/debug_cs_corner_uv.F for the case nSy > 1 (left from
1033        Jun 2009 modif of pkg/exch2).
1034    o testing on baudelaire:
1035      - run 2 tests at a time: no significant slow down (since enough cpu) and
1036        get the full set of test done earlier
1037      - switch the ifort test to "-devel" ; run the OpenAD test everyday.
1038    o model/src/thermodynamics.F and routines called from it:
1039      - pkg/gmredi: gmredi_residual_flow.F (replacing gmredi_calc_uvflow.F &
1040        gmredi_calc_wflow.F) to update eulerian velocity (input) into residual
1041        velocity (outp) by adding bolus velocity.
1042      - model/src: calc_adv_flow.F (replacing calc_common_factors.F) to compute
1043        mass transport from velocity + lateral grid cell area
1044      - rename calc_gt.F to temp_integrate.F (includes call to TIMESTEP_TRACER)
1045      - rename calc_gs.F to salt_integrate.F (includes call to TIMESTEP_TRACER)
1046     in thermodynamics.F
1047      - remove k from thermodynamics.F and move it to temp_integrate.F
1048        salt_integrate.F and ptracers_integrate.F (now done inside the tracer
1049        loop).
1050      - compute locally (in thermodynamics.F) 3-D velocity field that is used to
1051        advect tracers; pass it as argument to GAD_ADVECTION, GAD_SOM_ADVECT,
1052        PTRACERS_ADVECTION, TEMP_INTEGRATE, SALT_INTEGRATE, PTRACERS_INTEGRATE,
1053        GAD_IMPLICIT_R and PTRACERS_IMPLICIT
1054      - update AD-output (TAF & OAD) of experiments: 1D_ocean_ice_column,
1055        global_ocean.90x40x15, tutorial_global_oce_biogeo and
1056        tutorial_tracer_adjsens (+ TLM output).
1057    o tools/OAD_support and (verification/*/) code_oad:
1058      - OAD_support/cb2mGetModules.csh: add PACKAGES_CONFIG.h in header file to
1059        module conversion ; remove unneeded CPP_EEOPTIONS.h.
1060      - code_oad/CPP_OPTIONS.h: remove PACKAGES_CONFIG.h and use a more standard
1061        version (closer to model/inc/CPP_OPTIONS.h).
1062    o model/src:
1063      - remove parameter "useOldFreezing" from PARAMS.h and push it to the
1064        retired list of parameters (routine FREEZE has been replace by surface
1065        freezing (10.yrs ago) and by pkg/frazil (interior freezing).
1066    o pkg/gmredi:
1067      - add option (GM_CALC_TRANSP_FROM_VEL) to compute transport directly from
1068        velocity (same scheme but affects machine truncation) for GM_AdvForm.
1069      - update output of FWD experiments: front_relax.bvp,
1070        global_ocean.90x40x15.dwnslp, global_ocean.cs32x15 and ideal_2D_oce.
1071    
1072    checkpoint64q (2013/11/17)
1073    o verification:
1074      - generate new output on baudelaire (gfortran, -ieee) for OpenAD experiments
1075        tutorial_global_oce_biogeo and global_ocean.90x40x15.
1076      - generate new output (growth & melt) for seaice_itd experiment after
1077        updating the input pickup_seaice files (previously wrong).
1078    o pkg/cost:
1079      - define a "final cost function" for each tile, and use GLOBAL_SUM_TILE_RL
1080        (instead of _GLOBAL_SUM_RL) to get the final cost from all procs & threads:
1081        o this fixes global-sum value if multi-threads (since GLOBAL_SUM_RL
1082          cannot be applied to var in common block).
1083        o allows to get results independent of tile-per-proc setting (if using
1084          slower GLOBAL_SUM_SEND_RECV option).
1085      - update accordingly: seaice_cost_final.F, shelfice_cost_final.F,
1086        thsice_cost_final.F and ecco_cost_final.F (this one affects lab_sea
1087        forward gradients: update output).
1088      - update */code_oad/externalDummies.F by adding dummy GLOBAL_SUM_TILE_RL
1089        S/R and, for most exp., also comment out GLOBAL_SUM_R8.
1090    o pkg/mom_common:
1091      - move to pkg/mom_common and model/src (previously in tutorial_deep_convection
1092        code) 2nd version of isotropic 3-D Smagorinsky code interface: strain and
1093        viscosity are locally declared in dynmics.F and pass as argument to CALC_GW;
1094        ensure that all field value that are used are set.
1095    o tutorial_deep_convection (smag3d):
1096      - add missing scaling in mom_calc_smag_3d.F;
1097      - set smag3D_coeff in input.smag3d such that results do not change.
1098    o pkg/dic:
1099      - change dic_cost.F to compute cost on each tile first and then apply
1100        GLOBAL_SUM_TILE_RL: this affects forward gradient of AD experiments
1101        tutorial_dic_adjoffline & tutorial_global_oce_biogeo; update output.
1102      - remove kLev argument and use GLOBAL_SUM_TILE_RL in tracer_meanarea.
1103    o eesupp/src & pkg/mdsio:
1104      - remove gather/scatter_vector.F (from eesupp) and mdsio_read/writevector.F
1105        (from pkg/mdsio) since they are no longer used for tape IO.
1106      - move simple C subroutine "setdir.c" from pkg/compon_communic to eesupp/src
1107        (+ keep a copy in pkg/atm_ocn_coupler).
1108    o verification/isomip:
1109      - split domain in 8 squared tiles (instead of just 2) for FWD, AD & OAD tests.
1110    o tools/build_options:
1111      - optfile linux_amd64_ifort11, fast (no ieee) case:
1112        to get a working restart for all experiments, add "-fp-model source"
1113        to FOPTIM (also remove "-opt-streaming-stores auto" <- this is the default).
1114    
1115    checkpoint64p (2013/10/20)
1116    o pkg/autodiff:
1117      - adread_adwrite.F: when type and length do not match ALLOW_AUTODIFF_WHTAPEIO
1118        criteria, return to simple (default) tape IO format.
1119    o pkg/mdsio (+ eesupp/src):
1120      - rewrite/simplify tape-IO S/R (new S/R MDS_READ/WRITE_TAPE replace
1121        previous MDSREAD/WRITEVECTOR) with 2 array argument from each type (R4/R8);
1122      - fix globalFile and singleCpuIO options using simpler global mapping.
1123      - new pairs of scatter/gather vector S/R (one for each type, generated from
1124        template) corresponding to simpler global mapping.
1125      - adread_write.F: switch to new S/R (but leave old calls commented) and write
1126        to globalFile when parameter globalFiles is set to True.
1127      - switch on useSingleCpuIO in AD experiments: global_ocean.90x40x15 & isomip.
1128    o pkg/autodiff:
1129      - adread_adwrite.F: add a hack for RS arrays (when RS=real*4);
1130        with ALLOW_AUTODIFF_WHTAPEIO defined, since corresponding (real*4) is
1131        missing, just add a STOP if array type do not match.
1132    o pkg/exf:
1133      - to allow to use seaice-fraction from pkg/exf in other pkgs than pkg/seaice:
1134         rename CPP option EXF_ALLOW_SEAICE_RELAX to EXF_SEAICE_FRACTION
1135         and rename array obsSIce to exf_iceFraction.
1136    o tutorial_deep_convection:
1137      - add 1rst version of isotropic 3-D Smagorinsky code (from Louis-Philippe),
1138        for now all in this exp. code dir.
1139      - add secondary test using Smag-3D viscosity (keep very low backgroud visc for
1140        testing) and flux-limter advection scheme for Temp. (no explicit diffusion).
1141    o eesupp/src:
1142      - added SINGLE_DISK_IO option because reading of parameter files on
1143        very large number of processors did not work with existing set-up
1144    
1145    checkpoint64o (2013/09/25)
1146    o pkg/atm_phys & atm_compon_interf:
1147      - allows for coupling of gray-atmosphere (atm_phys) with ocean.
1148    o tools/build_options:
1149      - switch from "-fPIC" to "-mcmodel=medium" in optfiles: linux_amd64_gfortran
1150        & linux_amd64_ifort11 and in linux_amd64_g77 & linux_amd64_open64 also
1151        remove CPP setting (was identical to genmake2 default).
1152    o pkg/gmredi & model/src: Some updating and work done on the residual model.
1153      - created new file model/src/calc_eddy_stress.F to calculate the eddy stress.
1154      - fixed up the calculation of the eddy stress and how it is added to the
1155        external forcing via taueddy_external_forcing.F
1156      - at the moment, it is very experimental and only works with the variable eddy
1157        diffusivity calculated in gmredi_k3d.F
1158    o pkg/seaice/seaice_check.F: add a check to catch the case of specifying
1159        lw/swfluxfile instead of lw/swdownfile in data.exf together with pkg/seaice
1160    o testreport (& tools/do_tst_2+2):
1161      - for MPI test, set default COMMAND to 'mpirun -v -np TR_NPROC ./{executable}'
1162    o tools/build_options: linux_amd64_gfortran & linux_amd64_ifort11:
1163      - remove CPP='cpp -traditional -P' (this is genmake2 default)
1164      - add switch (for big setups) to use 'medium' memory-model (but leave it
1165        commented out for now). Note: needed with FC 19 to compile big setups.
1166    o pkg/atm_compon_interf:
1167      - regroup per field origin (model & pkgs) the coupling storage routines
1168         (which accumalate in time each coupling field)
1169      - move bi,bj loops inside atm_store_my_data.F and store also wind-stress;
1170        update accordingly + simplify aim_do_physics.F
1171    
1172    checkpoint64n (2013/08/26)
1173    o pkg/bbl:
1174      - update formulation to reduce dispersion of tracer properties in bbl
1175      - replaced horizontal and vertical transport parameters with velocities
1176      - changes results for verification/global_with_exf.yearly
1177    o verification/halfpipe_streamice:
1178      - change to matrix construction; update both Fwd & AD output.
1179    o verification/tutorial_tracer_adjsens:
1180      - OpenAD test: switch to vector-invariant momentum since fluxform with
1181        rStar causes problems with OpenAD; update output.
1182    o tools:
1183      - genmake2: define a common prefix for all temp-file names ; move them
1184        to local /tmp disk (but would be easy to move them back);
1185      - xmakedepend: apply the same switch for temp-files.
1186    o pkg/offline:
1187      - changes for use with rStar (NLFS): assume that we continue to provide
1188        UVELMASS/hFacW_ini & VVELMASS/hFacS_ini (hFacWi,S_ini as written in grid
1189        output files) and apply r* scaling at each time-step (function of the time
1190        varying Eta field); use normal pickup files (needed for restart with NLFS).
1191    o adjoint with OpenAD:
1192      - move OpenAD-specific files from verification/OpenAD/code_oad_all to a new
1193        package openad.  This package has to be compiled for all runs with OpenAD
1194        instead of specifying code_oad_all as a modification directory.
1195      - link the fortran templates from tools/OAD_support to the build directory
1196        for preprocessing to avoid conflicts between different setups compiled
1197        simultaneously and simplify cleanup.
1198    o pkg/exf:
1199      - in exf_getforcing.F: comment out most of the EXCH calls (fields used by
1200        main model or other pkgs are exchanged in EXF_MAPFIELDS).
1201    o model/src:
1202      - do_stagger_fields_exchanges.F: skip EXCH calls when using pkg/offline
1203        (similar to do_fields_blocking_exchanges.F).
1204    o tools/genmake2:
1205      - remove TAF output src code just before calling staf (when not doing a fresh
1206        built, will stop if things go wrong with staf).
1207      - fix target "adobj" (left from TAF version-2 transition)
1208    o pkg/diagnostics:
1209      - add a parameter to track the status of pkg/diagnostics activation;
1210        this replace/extend the use of logical param "settingDiags" (to check
1211        when adding diag to the list) to also check any DIAGNOSTICS_[]FILL* call.
1212        New S/R to print error message and stop when pkgStatus is not right.
1213      - to try: add a warning when "data.diagnostics" exist but useDiagnostics=F.
1214    
1215    checkpoint64m (2013/08/13)
1216    o model/inc:
1217      - move FCORI_MACROS.h from PARAMS(_MACROS).h to GRID_MACROS.h (left from
1218        8 yrs ago modif when Coriolis arrays were moved from PARAMS.h to GRID.h)
1219    o pkg/kpp & aim_v23:
1220      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
1221    o pkg/seaice:
1222      - restore (last time on 2011/12/24) ability to compile pkg/seaice with
1223        undefined pkg/exf ALLOW_ATM_TEMP or ALLOW_RUNOFF CPP-options.
1224      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
1225    o eesupp/src:
1226      - fix check for overlap-size argument (myOLn.GT.MAX_OLY_EXCH)
1227        in exch1_rx[_ad].template (thanks to Francois Lefeuvre report).
1228    o switch to TAF version-2:
1229      - add flow directives to "freeze" naming convention for ad-routines that
1230        are used in I/O routines of adjoint state and associated common blocks
1231        that are used in adcommon.h (backward compatible with version-1)
1232      - update all ad-optfiles (in tools/adjoint_options + few local to some
1233        verification exp) to switch to latest TAF version (currently 2.5.5);
1234        merge "*_mpi" adoptfiles into the corresponding non-mpi (but commented
1235        out except for diva).
1236      - the major change with TAF version-2 is that both the differentiated
1237        routines and the forward routines (new) are returned as part of the TAF
1238        output source code. Update genmake2 accordingly.
1239      - new output for AD experiment tutorial_global_oce_biogeo (better AD gradient
1240        with version-2 when compared to TLM or FWD gradient); other experiments
1241        output show minor changes (machine truncation level); update the few AD &
1242        TLM output with 12 matching digits only (some prior to version-2 switch).
1243    
1244    checkpoint64l (2013/08/05)
1245    o model/src:
1246      - in dynamics.F, skip the call to CALC_VISCOSITY if momViscosity=F
1247      - main_do_loop.F: no longer includes additional (AUTODIFF) header files
1248        when using TAF but only if using OpenAD.
1249    o pkg/mom_common+fluxform+vecinv:
1250      - always set horiz. viscosity arrays to background value before calling
1251        MOM_CALC_VISC (in MOM_FLUXFORM & MOM_VECINV) and call S/R MOM_CALC_VISC
1252        only when using variable horiz. viscosity (useVariableVisc=T);
1253      - simplify mom_vecinv.F (only 1 block for momViscosity).
1254    o pkg/mom_common: variable horiz. viscosity in NH code
1255      - move horiz-viscosity 3-D arrays viscAh_W & viscA4_W (used in calc_gw.F)
1256        from model/inc/NH_VARS.h to pkg/mom_common/MOM_VISC.h
1257      - store in common block (in MOM_VISC.h) logical parameters: useHarmonicVisc,
1258        useBiharmonicVisc & useVariableVisc.
1259      - fix old bug (already in 1rst implementation of variable horizontal viscosity
1260        in calc_gw.F, version 1.27, 2006/06/20):
1261        horizontal bi-harmonic viscosity in gW was missing when wiscA4W=0
1262        even if variable bi-harmonic viscosity (e.g., viscA4Grid) was non-zero.
1263      - change background horiz viscosity in vertical momentum (gW) to always be
1264        viscAhW,viscA4W (instead of switching to viscAhD, viscA4D when using
1265        any type of variable viscosity, e.g., viscAh/4Grid)
1266      - change default value of viscAhW,viscA4W to viscAhD,viscA4D (instead of
1267        viscAh,viscA4) which default to viscAh,viscA4 :  this avoid missing
1268        horiz. viscosity in W eq when just setting viscAhD/Z,viscA4D/Z (since
1269        default viscAh,viscA4 is zero).
1270    o model/src:
1271      - extend length of drC & recip_drC from Nr to Nr+1.
1272    o Divided Adjoint (DIVA) with MPI:
1273      - genmake2: do not create local ./mpi_headers dir when no file to copy into.
1274      - remove option ALLOW_DIVIDED_ADJOINT_MPI (replaced by ALLOW_DIVIDED_ADJOINT
1275        and ALLOW_USE_MPI) from model/src code and from ECCO_CPPOPTIONS.h.
1276    
1277    checkpoint64k (2013/07/23)
1278    o tools/OAD_support:
1279      - avoid the need for file "oadtempflile" in insertTemplateDir.bash
1280        and remove it from genmake2.
1281    o tools/build_options:
1282      - remove MPI_HEADER_FILES_INC setting (no longer used) and comment out
1283        MPI_HEADER_FILES list (let genmake2 find the missing headers)
1284    o verification/halfpipe_streamice:
1285      - change to driving stress formulation; update both Fwd & AD output.
1286    o tools/genmake2 and Divided Adjoint with MPI:
1287      - remove default setting of MPIINCLUDEDIR from $MPIHOME (always been broken);
1288      - only create local ./mpi_headers dir if using MPI and MPIINCLUDEDIR is set;
1289      - add new variable (LOCAL_MPI_HEADERS, replace MPI_HEADER_FILES_INC) in
1290        Makefile, which is set by genmake2, and check which mpi-headers are needed.
1291        Note: need to update adjoint_options/adjoint_diva_mpi accordingly.
1292      - update target "CLEAN" (to also remove ./mpi_headers/ dir).
1293    o testreport:
1294      - changes for Divided Adjoint Run: when file "run_ADM_DIVA" is present,
1295        perform additional runs (number of additional runs is "add_DIVA_runs" taken
1296        from file run_ADM_DIVA ; should match "nchklev_3" in file "code_ad/tamc.h").
1297    o verification/lab_sea (AD test):
1298      - change to test Divided Adjoint Run in this set-up (both standard AD test
1299        and 2 secondary AD test: noseaice + noseaicedyn); drop the evp AD test.
1300    o pkg atm_ & ocn_compon_interf:
1301      - remove cpl_earlyExpImpCall=F option (was mainly a hack added for the old
1302        staggerTimeStep implementation) and disable (retired) corresponding
1303        parameter.
1304    o pkg/offline:
1305      - comment out unused field-array: ICEM, ConvectCount, hflx[01], icem[01];
1306      - add S/R OFFLINE_CHECK to print offline parameter summary
1307        and stop if loading a file that is not used;
1308      - enable to calculate GMRedi tensor, KPP mixing and convective index
1309        when the corresponding file(s) is/are not specified (but pkg is used).
1310      - comment out resetting of monitorFreq (to endTime) since it still useful
1311        for monitoring CFL numbers and checking offline fields.
1312    o OpenAD:
1313      - do not define OAD_DEBUG (in tools/adjoint_options/adjoint_oad) to get
1314        smaller standard output) and generate new (smaller) output (on baudelaire
1315        using gfortran with -ieee) for exp. tutorial_tracer_adjsens
1316    o model/src:
1317      - call EXTERNAL_FORCING_SURF outside bi,bj loops (in do_oceanic_phys.F),
1318        (where external_forcing_adjust was called) and change list of arguments;
1319      - merge external_forcing_adjust.F into external_forcing_surf.F
1320      - put surface relaxation of SST & SSS in new S/R (forcing_surf_relax.F)
1321        which also contains balancing surface relaxation (ALLOW_BALANCE_RELAX,
1322        previously in file "balance_relax.F", now removed); remove corresponding
1323        arrays in FFIELDS.h.
1324      - EXTERNAL_FORCING_SURF is now called when using pkg/offline; implement
1325        a hack for getting back surfaceForcingS (loaded from file) when using
1326        ALLOW_OLD_VIRTUALFLUX (pkg/dic, in DIC_OPTIONS.h) in offline set-up.
1327      - update output of AD test experiment global_ocean.cs32x15.seaice_dynmix
1328        (was getting only 11 digits for AD-grad, due to different truncation
1329         error in AD code).
1330    
1331    checkpoint64j (2013/07/04)
1332    o pkg/offline:
1333      - to enable the use of other features with pkg offline (e.g., obcs),
1334        also call S/R DO_OCEANIC_PHYS in offline run - more modifs to come.
1335      - comment out "allowFreezing" (now active) in 2 offline testing exp.
1336    o pkg/exf ALLOW_RUNOFTEMP
1337      - fix sign and make compatible with temp_EvPrRn .NE. UNSET_RL
1338      - ahdded RUNOFTEMP test to verification/global_ocean.cs32x15/input.seaice
1339      - changes verification/global_ocean.cs32x15/results/output.seaice.txt
1340    o pkg/atm_phys:
1341      - allows to add some damping on uVel,vVel (strength only function of k).
1342    o verification, ad-tests:
1343      - reduce length of the simulation for AD test: global_ocean.cs32x15.seaice,
1344        global_ocean_ebm and offline_exf_seaice.thsice.
1345    o verification/halfpipe_streamice:
1346      - found a bug in s/r pkg/streamice/streamice_advect_thickness which caused
1347        flux input boundary conditions to be ignored; a fix for this bug changed
1348        verification results for forward test.
1349      - add adjoint test.
1350    o pkg/ptracers:
1351      - allow to restart without SOM pickup (resetting SOM to zero).
1352    o pkg/gmredi:
1353      - New parameterisation for the calculation of K and (GM_PsiX,GM_PsiY) added.
1354      - It uses mixing length theory and suppression by steering level effects to
1355        calculate a diffusivity used in the Redi tensor (see Bates et al., submitted
1356        to JPO, for more details).
1357      - It also uses the diffusivity to calculate an eddy induced streamfunction
1358        based on a PV closure (rather than a buoyancy closure as in GM).
1359      - New files added to pkg/gmredi:
1360        gmredi_k3d.F calculates the diffusivity for the Redi tensor and the eddy
1361          induced overturning streamfunction (called from gmredi_calc_tensor)
1362        gmredi_calc_eigs.F calculates the eigenvalues and eigenvectors required
1363          for use in gmredi_k3d
1364        gmredi_calc_urms.F calculates the the rms eddy velocity used to calculate
1365          the eddy diffusivity
1366    
1367    checkpoint64i (2013/06/18)
1368    o pkg/cheapaml:
1369      - take src files from MITgcm_contrib/verification_other/offline_cheapaml/code
1370        that enable the use of seaice (pkg/thsice thermo & pkg/seaice dynamics)
1371        with pkg/cheapaml.
1372    o utils/python: add subpackage for cubed sphere function, first example is
1373        simple cs.pcol to plot 2D fields on a map
1374    o pkg/streamice:
1375      - This is a new package in MITgcm, which solves dynamic equations for ice
1376         sheets and ice streams
1377      - At the moment it is independent of atmosphere/ocean dynamics, or any
1378        other physical packages in MITgcm, even ShelfIce (although it is anticipat-
1379        ed that this will change)
1380      - There is a new verification exercise that tests it, halfpipe_streamice,
1381        evolves a 40x80 km ice stream/ice shelf (at coarse resolution) in a
1382        rectangular embayment
1383      - halfpipe_streamice is forward-only for now, will have TAF test soon
1384      - for questions, email dgoldber@mit.edu
1385    o pkg/thsice:
1386      - fix filling of snow-precip diagnostic (SIsnwPrc) (left from the removing
1387        of snowPrc from common bloc, on May 2nd, thsice_step_fwd.F revision 1.40);
1388      - remove diagnostics 'SI_FrcFx' ( now identical to 'SI_Fract' with new
1389         call sequence: ice-Thermo(thsice),ice-Dyn,ice-Advect );
1390      - allow precip from pkg/cheapaml to make snow over seaice.
1391    o pkg/cfc:
1392      - move in separated header file (CFC_ATMOS.h) time-serie arrays of Atmos CFC
1393      - remove atmos CFC 2-D arrays from common bloc (now local variables)
1394      - change some hard-coded constant to run time parameter for reading and
1395        and interpolating atmospheric CFC ; keep same default as previously.
1396      - more flexible reading of Atmos CFC (number of records no longer hard-coded)
1397      - put arguments in standard order: myTime, myIter, myThid
1398      - use standard S/R GET_PERIODIC_INTERVAL for time interpolation of
1399        atmospheric CFC ; fix for the case myIter < PTRACERS_iter0.
1400      - fix calculation of surf tendencys for partial-cell and/or Non-Lin Free-Surf
1401      - new routine to print summary of CFC params and check for consistency.
1402    o pkg/seaice: add uice/vice to the parameter list of s/r seaice_advdiff,
1403      similar to thsice_advdiff.
1404      Note that for the B-grid case the routine parameters uc/vc are overwritten.
1405    o pkg/cfc:
1406      - change time interpolation for atmospheric CFC-11 (now same as for CFC-12);
1407        update output (CFC-11) of experiment cfc_example and tutorial_cfc_offline.
1408      - fix interpolation of atmphspheric CFC between Sorthern and Northern
1409        hemisphere value.
1410    o pkg/seaice:
1411      - allow to use seaice dynamics without pkg/exf (e.g., using pkg/cheapaml)
1412    o pkg/seaice: add Adams-Bashforth2 time discretization for ice dynamics;
1413                  so far only for JFNK-solver, turn on with SEAICEuseAB2 = .TRUE.
1414      - requires an additional time level that is stored in the pickup
1415      - you can start with AB2 from a pickup without this time level with
1416        pickupStrictlyMatch = .false.
1417    
1418    checkpoint64h (2013/05/26)
1419    o pkg/cheapaml:
1420      - replace one ()**.5 with SQRT + use temp var "cdu = tau/Du" (coare3_flux);
1421        affect machine truncation (but exp cheapAML_box still pass with 13 digits).
1422      - consistent treatment of uWind,vWind location: assume everywhere in
1423        pkg/cheapaml that they are on C-grid (@ uVel,vVel location)
1424        (Note: was already the case for Tair,Qair advection);
1425        add option (INCONSISTENT_WIND_LOCATION) to recover old results.
1426      - compute diabatic forcing only in the interior (excluding overlap regions)
1427      - fill in array "Qsw" (for short-wave heating);
1428      - add diagnostic for precip ; fill-in diagnostics for cheapAML state vars
1429        before any update (consistent with MITgcm state var diagnostics);
1430      - cheapaml_fields_load.F & cheapaml_init_varia.F : only fill outer edges if
1431        non periodic ; + adjusted for uWind,vWind (C-grid).
1432    o pkg/seaice:
1433      - remove dependence of pkg/seaice versus pkg/exf (file: pkg/pkg_depend) and
1434        add explicitly pkg/exf in experiments that currently use pkg/seaice.
1435      - allows to compile pkg/seaice without pkg/exf.
1436    o tools/OAD_support:
1437      - use a local copy (ourRWCPinBd) to ensure index ourRWCP stays within bounds
1438        of array "ourStepOf" in function rvNextAction (revolve.F90).
1439    o pkg/aim_compon_interf renamed to pkg/atm_compon_interf
1440      - change pkg name (to be used with other atmospheric physics pkg)
1441        but by-pass CVS when making the new pkg so that we keep the CVS history.
1442    o pkg/offline:
1443      - call OFFLINE_FIELDS_LOAD from pkg/offline/offline_init_varia.F
1444        (previously called from pkg/dic_surfforcing_init.F)
1445    o model/src:
1446      - re-order sequence of calls within packages_init_variables.F, using
1447        standard order, except for:
1448         DIAGNOSTICS_INIT_VARIA and OFFLINE_INIT_VARIA (called @ the top),
1449         CTRL_MAP_INI and OBCS_INIT_VARIABLES (called @ the bottom)
1450    o new pkg: atm_phys
1451      - add entry point and source code (previously in contrib
1452          verification_other/atm_gray/code_gray/) for new pkg "atm_phys"
1453        (atmospheric physics pkg from P. O'Gorman and T. Schneider, JCl, 2008).
1454      - re-order sequence of calls within packages_readparms.F,
1455         packages_init_fixed.F and packages_write_pickup.F
1456        (but skip packages_init_variables.F because of TAF issues).
1457      - update contrib/*/atm_gray/ experiment.
1458    o pkg/seaice (ITD code):
1459      - simplify and fix the writing of pickup-files for ITD case
1460    o pkg/seaice (ITD code):
1461      - introduce floe size dependent lateral melt for ITD case;
1462      - cleaning (avoid division by zero, change to f77 syntax, remove tabs)
1463      - update seaice_itd experiment main output.
1464    o pkg/thsice:
1465      - remove snowPrc from common block THSICE_FLUX, in THSICE_VARS.h and
1466        declared it locally (without bi,bj) in thsice_main.F & aim_do_physics.F;
1467        changed accordingly pkg/atm2d.
1468    
1469    checkpoint64g (2013/05/01)
1470    o pkg/exf ALLOW_RUNOFTEMP
1471      - if defined,  river and glacier runoff temperature can be read-in from
1472        runoftempfile; runoftempfile needs to have same format as runofffile
1473    o pkg/thsice (& pkg/bulk_force):
1474      - In case Energy-Reference-Level (ERL) is used (temp_EvPrRn=0), account
1475        for energy content of Precip + RunOff & Evap (like with pkg/exf).
1476      - change computation domain to always be the interior (without overlap).
1477      - fix bug (wrong overlap) when using EXF and stressReduction > 0.
1478    o verification/tutorial_global_oce_biogeo:
1479      - add preliminary OpenAD setup (still has problems)
1480    o pkg/seaice:
1481      - turn some parameters for choosing the convergence criterion of
1482        the inexact Newton method (JFNK) into runtime parameters for convenience
1483      - clean up seaice_calc_viscosities.F: remove/retire two options for
1484        SEAICetaZmethod (1,2), introduce area weighting for method 3; this changes
1485        the results of lab_sea/input because a division has been replaced by
1486        a multiplication with the reciprocal (sumNorm)
1487      - modify offline_exf_seaice/input.dyn_jfnk/data.seaice to improve
1488        convergence of solver (changes results, of course), and to test some
1489        new features
1490    o model/src:
1491      - remove unused (since Aug 2006) S/R SET_WRITE_GLOBAL_PICKUP and its call.
1492      - remove unused forcing field "dQdT" and associated parameter "dQdTFile".
1493      - move forcing adjustment (balancing surface forcing) in specific S/R
1494        where might also be applied exchanges (if needed) to forcing arrays.
1495    o pkg/shelfice:
1496      - allow to specify the Ice-Shelf mass per unit area (instead of
1497        shelficeLoadAnomaly) and do the conversion from one to the other
1498      - move loading from file of shelficeLoadAnomaly from SHELFICE_INIT_VARIA
1499        to SHELFICE_INIT_FIXED: (a) avoid some TAF recompution issues and
1500        (b) will be loaded in time (before calling INI_PRESSURE) in case it is
1501        needed in phi0surf for initial pressure calculation when useDynP_inEos_Zc
1502      - update isomip experiment forward output (get machine truncation error
1503        from conversion shelficeLoadAnomaly -> shelficeMass -> shelficeLoadAnomaly)
1504    o verification/offline_exf_seaice:
1505      revise data.seaice in input.thermo and input_ad and update results accordingly
1506        HO = 0.2, SEAICE_areaLossFormula = 2,
1507        SEAICE_growMeltByConv = .TRUE.,
1508        SEAICE_doOpenWaterMelt = .TRUE.,
1509      Improve consistency with input.thsice and fix the spurious 500m ice corners
1510    o verification/global_ocean.cs32x15:
1511      - set Energy Reference Level to liq. water @ 0 degC: temp_EvPrRn=0.,
1512        in icedyn (thsice+seaice-dyn) test and update output.
1513    o verification/offline_exf_seaice:
1514      - adjust list of tested variables (with testreport) and update
1515        standard test output with better slection of monitored fields.
1516    o pkg/cd_code:
1517      - swtich off Adams-Bashforth on the 1rst iteration. Update output of
1518        experiment lab_sea.hb87
1519    o tools/genmake2:
1520      - change default makedepend from the system default to tools/xmakedepend:
1521        When no makedepend is specified, select tools/xmakedepend it the test pass,
1522        otherwise select the system default (if exist and pass the test) or
1523        try to build cyrus-makedepend ; stop if none of the 3 works.
1524    o pkg/exf & pkg/thsice:
1525      - In case Energy-Reference-Level (ERL) is used (temp_EvPrRn=0), account
1526        for energy content of Precip + RunOff & Evap. Assumes:
1527       1) Rain has same temp as Air.
1528       2) Snow has no heat capacity (consistent with seaice & thsice pkgs)
1529       3) Run-Off comes at the temp of surface water (with same Cp)
1530       4) Evap over ocean is released to the Atmos @ surf-temp (=SST); should be
1531        put directly into Latent Heat flux & should use water-vapor heat capacity.
1532       5) Evap over snow/seaice (pkg/thsice) assumes constant Lf+Lv (consistent
1533        with snow having no Cp) => water vapor is released to Atmos @ 0^oC (=ERL).
1534    o pkg/seaice: simplify the use of CPP flags in JFNK-related files
1535        (compile when SEAICE_ALLOW_JFNK is defined)
1536    o pkg/thsice:
1537      - fix oceanic flux diagnostics & timeave (left from new sequence of calls
1538        implementation): move THSICE_AVE call after the advection (called directly
1539        from thsice_do_advect.F).
1540    o verification/global_ocean.90x40x15 and OpenAD:
1541      New experiment for OpenAD is identical to the one in input_ad except that
1542        multiDimAdvection=.FALSE.,
1543      There is still an issue with this.
1544    o pkg/thsice:
1545      - account for ice velocity (ocean relative velocity) in turbulent heat flux
1546        at the base of the ice; update output of global_ocean.cs32x15 (icedyn)
1547        and offline_exf_seaice (main test).
1548    
1549    checkpoint64f (2013/03/31)
1550    o verification/OpenAD:
1551      - new (smaller, without OAD_DEBUG) output_oadm.txt generated using gfortran.
1552    o verification/isomip, pkg/shelfice and OpenAD:
1553      - add OpenAD setup to this exp and make shelfice package work with OpenAD
1554    o verification/tutorial_global_oce_biogeo:
1555      - update AD and TLM output after turning off ALLOW_FE (in DIC_OPTIONS.h)
1556    o verification/offline_exf_seaice:
1557      - replace adjoint experiment (now similar to fwd input.thermo/ setup).
1558    o verification/tutorial_tracer_adjsens, pkg/ptracers and OpenAD:
1559      - add OpenAD setup to this exp and make ptracers package work with OpenAD
1560    o pkg/seaice/seaice_evp.F:
1561       mask the asymmetric contribution of the ice-ocean stress (when
1562       the turningAngle is non-zero) over open water to avoid stripes
1563       in the EVP-solutions after many EVP-substeps. This does not change
1564       the verification experiment (because turningAngle=0 in that experiment),
1565       but will affect other EVP solutions with turningAngle.ne.0
1566    o verification, AD & TLM output:
1567      - new TAF version 2.3.10 (previously 2.3.8) add more parenthesis in multiple
1568        additions and multiplications which affect results at machine truncation
1569        level. Update few AD output (1D_ocean_ice_column, bottom_ctrl_5x5,
1570        lab_sea.noseaicedyn & offline_exf_seaice) and TLM output
1571        (1D_ocean_ice_column & tutorial_tracer_adjsens.som81) which had only 12
1572        digits of matching.
1573    o pkg/seaice:
1574       modify lsr-algorithm so that it vectorizes AND converges by using a
1575       "zebra" method: split vector loop into two with step size 2; this
1576       solves a general convergence problem for the JFNK solver on a vector
1577       computer. It has the potential to even improve convergence for
1578       non-vector machines, but it does change the results so it is turned
1579       off by default. To turn on define CPP-flags SEAICE_VECTORIZE_LSR and
1580       SEAICE_VECTORIZE_LSR_ZEBRA in SEAICE_OPTIONS.h
1581    
1582    checkpoint64e (2013/03/05)
1583    o pkg/ecco and several verification experiments:
1584       Remove special versions of the_model_main.F, the_main_loop.F, forward_step.F
1585       from ecco package, and revert to unified routine in model/src/
1586       Adjust verification experiments accordingly, especially gloal_oce_llc90
1587       Should conclude long-standing work by Gael to reconsile the_main_loop with
1588       ECCO and will enable OpenAD's revolve loop in ECCO setup.
1589    o pkg/generic_advdiff:
1590      - implement compressible flow method for multi-dim advection (similar to
1591        gad_som_advect.F); add new option "GAD_MULTIDIM_COMPRESSIBLE" (since
1592        TAF generates many recomputations) to use it; no yet coded with implicit
1593        vertical advection.
1594      - change experiment advect_cs (new output) and advect_xy (same output)
1595        to test compressible flow multi-dim advection.
1596    o pkg/generic_advdiff:
1597      - fix SOM advection for unusual cases (linear Free-Surf in r*, other
1598        cases where linear Free-Surf is not @ k=1, e.g., useShelfIce)
1599    o pkg/seaice:
1600      - fix bug in the no-slip implementation in seaice_calc_strainrates.F, this
1601        bug affects two verification experiments (lab_sea and lab_sea.hb87),
1602        recover old (wrong) results by setting noSlipFac = 2. in
1603        seaice_calc_strainrates.F;
1604      - add another averaging method for etaZ (etaZmethod=3), a mix of 2 and 0
1605      - add runtime parameter SEAICE_JFNKepsilon for that finite difference
1606        gradient in the Jacobian times vector operation (s/r seaice_jacvec)
1607      - fix line search in seaice_jfnk.F (s/r seaice_jfnk_update)
1608    o pkg/seaice: reorganize seaice_lsr.F to be able to reuse more code:
1609      - new subroutines seaice_lsr_tridiagu/v
1610      - introduce loop bounds i/jmin/max to be able to use a restricted
1611        additive Schwarz method, but not used for now.
1612      - rename SEAICE_CALC_LSR_COEFFS into SEAICE_LSR_CALC_COEFFS
1613      - use new subroutines seaice_lsr_tridiagu/v in s/r seaice_preconditioner
1614    o OpenAD support
1615       Reorganize S/R call for overall time-stepping loop to facilitate
1616       OpenAD revolve loop replacement
1617       (new S/R main_do_loop.F)
1618    o model/src:
1619      - add 3-D array 3rd dimension to argument list of S/R ADAMS_BASHFORTH2/3;
1620      - pkg/cheapaml: remove local S/R ADAMS2d and use instead standard S/R
1621        ADAMS_BASHFORTH2.
1622    o pkg/cheapaml:
1623      - add new parameter (default=F, same as before) to disable full domain
1624        (including land) periodicity in X & Y dir.
1625      - new S/R CHEAPAML_COPY_EDGES to copy relaxation field into edges of
1626        prognostics field ; merge the 2 S/R cycle_2d_tracer and timestep_2d_tracer
1627        into single S/R CHEAPAML_TIMESTEP.
1628    
1629    checkpoint64d (2013/02/17)
1630    o pkg/monitor (angular momentum):
1631      - do not add Eta contribution to the total AM if using rigid-lid;
1632      - correct for Adams-Bashforth in zonal-wind part (instead of in AM_eta).
1633      - horizontal discretisation: compute Zonal wind contribution separately for
1634        each component (instead of from cell centered averaged) and use the 4
1635        grid-cell corner averaged value of Omega*(R*cos_Phi)^2 in AM_eta part.
1636      - Check that AM is conserved with linear dynamics (momAdvection=F and linear
1637        FreeSurf) if using vectorInvariant momentum.
1638    o model/src (horizontal grid):
1639      - move initialisation of all horizontal grid arrays to null value
1640        from specific horizontal grid S/R to main S/R INI_GRID;
1641      - add 2 new arrays to project model C-grid velocity on to zonal direction
1642        (similar to AngleCosC & -AngleSinC but at U and V point location) and
1643        compute them in S/R CALC_GRID_ANGLES.
1644    o pkg/seaice: replace a hard coded parameter by a runtime parameter
1645        SEAICE_JFNK_tolIter
1646    o pkg/seaice: introduce a restricted additive Schwarz (RAS) method in
1647        preconditioner for JFNK (run LSR into the overlaps as far as possible,
1648        i.e OLx/y-2, but overwrite the solution in the overlaps)
1649      - extend loop range in seaice_calc_viscosity
1650      - add new parameters SEAICE_OLx/y (default = OLx/y-2)
1651      - add flexible loop ranges to seaice_preconditioner, seaice_calc_lsr_coeffs
1652      - slightly modify loops in tridiagonal solver lsr-preconditioner
1653      - by default remove the extra exchange in seaice_preconditioner with a
1654        replacement of an undocumented CPP flag by SEAICE_PRECOND_EXTRA_EXCHANGE
1655      - modify offline_exf_seaice so that old results without RAS are reproduced
1656        for output.dyn_jfnk.txt
1657      in seaice_fgmres.F (unrelated to RAS)
1658      - add a cpp-flag option for a re-ordered mapping (potentially more
1659        efficient), but because this changes the results, turn it off by
1660        default
1661      - replace the save statement by local common blocks
1662    o utils/matlab:
1663      - fix tile-offset in rdmnc.m when output was produced using EXCH2.
1664      - update cs_grid/bk_line scripts to use load_grid.m (in utils/matlab)
1665        instead of local script "load_cs.m".
1666    o pkg/seaice:
1667      - fix a serious bug in seaice_fgmres.F, s/r seaice_scalprod, connected
1668        to the scalarProductMetric and the unrolling. By chance this does not
1669        change the verification experiment, because of the particular domain
1670        decomposition
1671    o pkg/diagnostics:
1672      - change default missing_value from UNSET_RL to -999.
1673    o pkg/layers: improve vectorization of layers_fluxcalc.F
1674      - step 1: split loops, make TatU/V 2D arrays. This alone reduces the cpu
1675        time spent in this routine by more than a factor of 3 on an NEC-SX8
1676      - step 2: replace search algorithm by a bisection algorithm found in
1677        Press et al. Numerical Recipes in Fortran. This algorithm can be
1678        vectorized and finds the correct bin in approx. log2(Nlayers) steps.
1679        For now, use this algorithm only for TARGET_NEC_SX defined.
1680      - moved the search algorithm into a separate subroutine, that is kept
1681        within the same file for automatic inlining.
1682      - modified catching potential errors
1683    o pkg/ecco:
1684      - add compile switches ALLOW_SHALLOW_ALTIMETRY and ALLOW_HIGHLAT_ALTIMETRY.
1685    o model/src, pkg/autodiff, pkg/ctrl, pkg/grdchk :
1686      - modifications for ALLOW_GENTIM2D_CONTROL
1687      -- forward_step.F, the_main_loop.F : pass options and arrays for adjoint tapes.
1688      -- load_fields_driver.F : add call to CTRL_MAP_GENTIM2D( myTime, myIter, myThid )
1689      -- add xx_gentim2d0/1 in ctrl_ad_check_lev1_dir.h checkpoint_lev1_directives.h etc
1690      -- use ctrl_swapffields.F (new) instead of exf_SwapFFields.F in ctrl_get_gen.F
1691    o model/src:
1692      - account for moist thermodynamics in (dry) potential temperature equation;
1693        update results of experiments: aim.5l_cs (x2), fizhi-cs (std + aqualev)
1694        and cpl_aim+ocn.
1695      - also switch to standard compiler (gfortran, was using ifort previously)
1696        for fizhi-cs experiments reference output.
1697    o pkg/ctrl:
1698      - 1st step toward generic time-varying control variable (2D) via CPP option
1699        ALLOW_GENTIM2D_CONTROL
1700      - note new namelist ctrl_nml_genarr in data.ctrl
1701    o verification/global_ocean.cs32x15:
1702      - switch off OLD_THSICE_CALL_SEQUENCE (both forward and AD code) to use new
1703        thsice calling sequence and update "output.icedyn.txt" output file.
1704    o pkg/ptracers:
1705      - from Ryan A.: code to allow to restart a tracer at regular time interval
1706        specifying a reset frequency and a reset-phase (for each tracers).
1707    o pkg/thsice:
1708      - implement new sequence of calls for thsice+seaice:
1709          previously:   ice-Dyn,ice-Advect,ice-Thermo(thsice)
1710          new sequence: ice-Thermo(thsice),ice-Dyn,ice-Advect
1711      - allows (with temporary CPP option "#define OLD_THSICE_CALL_SEQUENCE"
1712        in CPP_OPTIONS.h) to recover old sequence;
1713      - update diagnostics for Intermediate State thsice diagnostics: now filled
1714        just before advection (instead of just after advection in old sequence);
1715      - update output of experiment offline_exf_seaice (standard test);
1716      - in global_ocean.cs32x15 exp., postpone output.icedyn.txt update
1717        by setting #define OLD_THSICE_CALL_SEQUENCE in CPP_OPTIONS.h
1718    o pkg/aim_v23:
1719      - use tiled array for aim_CO2 and surface wind speed for export to coupler;
1720      - use standard pkg/mdsio routines to read & write CO2 pickup file;
1721      - in-line S/R AIM_AIM2DYN_EXCHANGES in aim_do_physics.F;
1722      - Implement new sequence of calls for seaice advection (with thsice and
1723        seaice diffusion): do ice advection after ice-Thermodynamic (previously
1724        was done before); change aim_do_physics.F (split the bi,bj loops block);
1725      - use same CPP option (OLD_THSICE_CALL_SEQUENCE) to recover old sequence;
1726    o pkg/thsice:
1727      - add a missing EXCH of sIceLoad in thsice_main.F (ocean set-up) for the case
1728        where just seaice diffusion is used without seaice-dynamics.
1729    
1730    checkpoint64c (2013/01/18)
1731    o pkg/seaice:
1732      - add a parameter JFNKres_tFac that can replace JFNKres_t
1733        (= JFNKres_tFac*JFNKresidual before JFNK solver)
1734      - add a line search option to the JFNK solver
1735      - move update of u/vIce and computation of initial residual into a separate
1736        routine (same file); makes the code a little easier to read (?)
1737      - the line search requires computation of the residual and for some reason
1738        I cannot do the update of u/vIce at the beginning of the Newton loop
1739        without changing the results, so we move computation of the new residual
1740        also to the end of the Newton loop, even without the line search
1741    o pkg/mdsio:
1742      - write missing value (corresponding to undefined array value) to meta files;
1743        skip this if missing value is one (UNSET_RL would be a better value for the
1744        case of undefined missing value but it's current the default missing-value);
1745        Also update mdsio_read_meta.F (reading timeInterval & missing-value).
1746    o pkg/exf & thsice:
1747      - for diagnostics purpose, fill-up and update Qsw array (+ fill the
1748        diagnostics) even when SHORTWAVE_HEATING is #undef;
1749    o verification/cfc_example:
1750      - turn on pkg/layers with pkg/diagnostics (to test pkg/layers and to
1751        illustrate how to use it).
1752    o verification/offline_exf_seaice:
1753      in input: add SEAICErestoreUnderIce=.TRUE., and reduce size of forcing
1754        files to only one time-record.
1755      in input.thermo: narrow the 2 bands of low initial ice-concentration near
1756        N & S edges; switch on SEAICErestoreUnderIce=T; use pkg/diagnostics for
1757        snapshot output; same mcPheePiston value as in thsice with
1758        surf-current=0.2m/s.
1759      in input.thsice: similar set-up as in input.thermo (channel with same seaice
1760        initial conditions).
1761    o verification/cfc_example:
1762      - update file "data" with more standard choice (default rotationPeriod,
1763        exactConserv=T, reduce ivdc_kappa to 10, remove multiDimAdvection=F,
1764        set deltaTFreeSurf to deltaTtracer) and update the output.
1765    o pkg/layers:
1766      - fix bolus part so that it compiles with #undef GM_BOLUS_ADVEC;
1767      - ensure that "layers_bolus" is switched to False when useGMRedi=False.
1768    o verification/offline_exf_seaice:
1769      - set all {field}period to zero for constant-in-time forcing (not tested
1770        anywhere else).
1771    o verification/offline_exf_seaice:
1772      - dyn_lsr  : use pkg/seaice S/R (instead of pkg/thsice) to advect sea-ice;
1773      - dyn_jfnk : use pkg/thsice S/R (instead of pkg/seaice) to advect sea-ice.
1774    o model/src:
1775      - implement Finite-Volume method for (hydrostatic) presure gradient
1776        from S.-J. Lin (QJRMS 1997), for atmosphere using sigma-coordinate.
1777    o pkg/seaice: implement EVP* by Lemieux et al. (2012).
1778      - In order to be compatible with the default EVP code, this requires changing
1779        the EVP code around a little; and because any small change immediately
1780        breaks the lab_sea.hb87 verification experiment, the reference output is
1781        updated two times (each time the remaining aggrement was only 2 digits):
1782        - after replacing 1/dt by 1*recip_dt with a precomputed recip_dt
1783        - after replacing 1/(1+0.5*dt/tau) by a/(a+1), with a=2*tau/dt
1784        The adjoint test lab_sea.evp also needed to be updated.
1785      - Turn on EVP* by setting SEAICE_deltaTevp as before, and setting
1786        SEAICEuseEVPstar=.true.; for EVP* SEAICE_deltaTevp does not need to be
1787        a factor of SEAICE_deltaTdyn, and you can set the number of EVP steps
1788        explicitly with SEAICEnEVPstarSteps (thereby overriding the default of
1789        INT(SEAICE_deltaTdyn/SEAICE_deltaTevp)). Controlling EVP* is deliberately
1790        kept obscure, because I need to test it a little more.
1791    o pkg/cheapaml:
1792      - fix few incorrect type (_RL/_RS) in subroutine calls.
1793    o pkg/seaice:
1794      - new S/R SEAICE_MAP_RS2VEC (similar to SEAICE_MAP2VEC) to map _RS arrays
1795        to _RL vector; this fixes JFNK code when compiling with "-use_r4" option.
1796    o model/src:
1797      - add a warning if using select_rStar=2 with nonlinFreeSurf <> 4;
1798        change (in input_ad*/data) select_rStar from 2 to 1 for AD verification
1799        experiments global_ocean.cs32x15 & tutorial_tracer_adjsens (+ update output)
1800    o pkg/cheapaml:
1801      - replace "273.1 _d 0" by celsius2K in pkg/cheapaml/cheapaml.F and
1802        update output of experiment cheapAML_box.
1803      - store in CHEAPAML.h coeffs ssq[0:2] for saturation specific humidity,
1804        and set them only in one place (cheapaml_readparms.F).
1805      - replace "273.16 _d 0" by celsius2K & replace "3.14159 _d 0" by constant "PI"
1806      - remove re-setting of main-model parameter "celsius2K" (in cheapaml_readparms)
1807        and re-setting of cheapAML params "lath" & "p0" (in cheapaml_init_varia).
1808    o model/src/the_main_loop.F:
1809      - fix revision 129 : need both ALLOW_ECCO and ALLOW_ECCO_EVOLUTION.
1810    o pkg/seaice:
1811      - remove legacy branch code.
1812      - retire SEAICE_GROWTH_LEGACY and SEAICE_CAP_HEFF accordingly.
1813    o verification/*/code*/SEAICE_OPTIONS.h:
1814      - remove documentation for retired CPP flags (SEAICE_GROWTH_LEGACY,
1815        SEAICE_CAP_HEFF).
1816    o pkg/cheapaml:
1817      - use standard routine (S/R GET_PERIODIC_INTERVAL) to decide when it is time
1818        to load new forcing fields.
1819      - add missing "_d 0" where it's needed; + some editing (improve indentation).
1820      - remove switch to "-r8" compiler option (no longer needed) in verification
1821        cheapAML_box, keep same output (small trucation error differences).
1822    o verification/offline_exf_seaice:
1823      - add thermodynamics only test.
1824    o verification/cheapAML_box:
1825      - split the domain in 8 (2x4) tiles; add MPI and multi-threaded test;
1826        keep same output (same 14 digits for cg2d).
1827      - switch on "-r8" compiler option (some numerical values are missing
1828        the "_d 0") and update output (only 6 digits for cg2d were preserved).
1829    
1830    checkpoint64b (2012/12/24)
1831    o pkg/cheapaml:
1832      - remove un-used variables (Qnet,EmPmR) from pickup files.
1833      - store tendency of advected variables into cheapaml pickup file
1834        and fix the AB-2 restart.
1835    o verification/offline_exf_seaice and lab_sea adjoint:
1836      - switch to new code (#undef SEAICE_GROWTH_LEGACY).
1837      - switch to 4 time steps in offline, consistent with lab_sea.
1838      - match parameters from SEAICE_GROWTH_LEGACY branch in data.seaice.
1839      - update results after change of experiment seaice.
1840    o pkg/seaice:
1841      - remove option SEAICE_MULTICATEGORY; has been replaced with run-time
1842        parameter SEAICE_multDim. Issue a warning if SEAICE_MULTICATEGORY is
1843        still defined since SEAICE_multDim needs to be set to MULTDIM value (from
1844        SEAICE_SIZE.h) to recover previous #define SEAICE_MULTICATEGORY default.
1845    o model/src:
1846      - add run-time parameter to select CG2D solver minimum-residual solution
1847        (in case of a poor convergence).
1848    o pkg/seaice/seaice_lsr.F
1849      - move calculation of matrix coefficients into new
1850        S/R SEAICE_CALC_LSR_COEFFS; for now this routine remains in the same
1851        file; the main purpose of this change is to be able to reuse the code
1852        in S/R SEAICE_PRECONDITIONER
1853      - modify the computation of the residual so that the mass of sea-ice
1854        is not used twice; this simplifies the calculations, but since
1855        the residual is never used except when LSR_mixIniGuess.ge.4---and this is
1856        not tested in testreport---this does not affect the testreport results.
1857    o verification/seaice_obcs:
1858      - disable SEAICE_GROWTH_LEGACY; reset input files to match those of
1859        verification/lab_sea/input.salt_plume; changes results/output.txt*
1860    o model/src:
1861      - adapt quasi-hydrostatic formulation to work with p or p* coordinate.
1862    o pkg/seaice:
1863      - improve description of parameters in seaice_fgmres.F and start
1864        cleaning up the code
1865      - change name of SCALPROD to SEAICE_SCALPROD and modify meaning of
1866        second argument
1867      - add a metric based on grid cell area to SEAICE_SCALPROD; update
1868        results of offline_exf_seaice.dyn_jfnk
1869      - compute initial residual norm in seaice_jfnk based on SEAICE_SCALPROD
1870    o pkg/aim_v23:
1871      - fix an other bug in dissipation heating (grid-cell area was missing).
1872    o model/src + pkg/seaice:
1873      - add global (multi-tile) linear solver for pair of tri-diagonal system
1874        along X and Y lines, respectively for U and V component.
1875        Note: 1) MPI and cube-exchange not yet coded.
1876            2) probably not accurate for poorly conditioned / large size problem.
1877      - add option for SEAICE_LSR to use global (multi-tile) tri-diagonal solver;
1878        default: not compiled and not used.
1879    o pkg/seaice:
1880      - first attempt at a multi-threaded fgmres solver for the JFNK solver:
1881        introduce bi/bj loops and use global_sum_tile_rl instead of
1882        mpi_allreduce in seaice_fgmres.F
1883      - improve diagnostics output for fgmres solver (seaice_fgmres.F)
1884      - replace a few unnecessary goto statements by if-blocks  (seaice_fgmres.F)
1885      - add a verification experiment for JFNK in offline_exf_seaice
1886    o verification:
1887      - change (for now, only fwd test) offline_exf_seaice experiment:
1888        use a re-entrant channel with idealized coastline (trapezoidal shape)
1889        at southern boundary to explore seaice dynamics and thermodynamics
1890        with simple forcing. Main set-up has dynamics+thermo and SST relaxation;
1891        secondary test (input.thsice) use thermodynamics only with SST relaxation.
1892      - add seaice-dynamics only secondary test using LSR and pkg/thsice advection.
1893    o pkg/exf:
1894      - disable "sstExtrapol" when Nr=1
1895    o verification:
1896      - add new experiment "cheapAML_box" (simple 1 layer set-up from Bruno Deremble)
1897        to test pkg/cheapaml.
1898    o pkg/aim_v23 & pkg/shap_filt:
1899      - fix dissipation heating (erroneous gravity multiplication factor).
1900    o pkg/seaice:
1901      - remove unused field pressPre from jfnk solver
1902      - rename two subroutines in seaice_preconditioner.F
1903    o eesupp/src:
1904       - S/R MDSFINDUNIT avoids reserved unit numbers (scrUnit1, eeDataUnit ...)
1905    o pkg/seaice/seaice_preconditioner.F: fix preconditioner once again
1906       - remove wrong parts of the rhs and the lhs (were in there
1907         because I did not understand the concept of this preconditioner)
1908       - add an exchange between u- and v-sweep. This increases communication
1909         by a factor of two but improves the convergence of jfnk. Ideally,
1910         one would like the u- and v-sweep to be independent. So far within
1911         undocumented ifdefs
1912       - reorganize the extra computations for printing the residuals
1913    o tools/genmake2:
1914      - comment out the "mpif.h" include in NetCDF test programm (for MPI built)
1915        since it's not necessary (and was preventing to use MNC in some cases).
1916    
1917    checkpoint64a (2012/11/16)
1918    o pkg/autodiff:
1919      - improve pkg-internal logical parameter switch (inAd/inFwd mode) so that
1920        autodiff_readparms.F no longer depends on calling order (within
1921        packages_readparms.F) and no longer requires to include ${PKG}_PARMS.h):
1922        rename param turnFreeDriftInAdMode to SEAICEuseFREEDRIFTswitchInAd
1923        and change param SEAICEuseDYNAMICSinAdMode to SEAICEuseDYNAMICSswitchInAd.
1924    o pkg/obcs:
1925      - adding tidal velocity forcing capability to obcs
1926        for usage example, see verification/seaice_obcs/input.tides
1927    o pkg/seaice:
1928      - turn the LSR-relaxation parameters WFAU/V into runtime parameters
1929        SEAICE_LSRrelaxU/V
1930      - introduce runtime parameter SEAICEetaZmethod (=0 by default)
1931    o pkg/aim_v23:
1932      - implement heating from friction (bottom friction and stratospheric drag).
1933    o pkg/shap_filt:
1934      - fix diagnostic "SHAP_dKE" (was 2 time smaller); implement heating from
1935        dissipation but only for Shap_funct=2, active when addFrictionHeating=T.
1936    o model/src:
1937      - move AddMass common block from DYNVARS.h to FFIELDS.h; allow to read-in
1938        time-constant addMass field from file (addMassFile);
1939      - support for heating due to friction (and Kinetic Energy dissipation):
1940        add option, run-time switch and 3-D field array + support code ; each pkg
1941        or S/R can add heating contribution (if there is a sink of KE); the sum is
1942        accounted for as a Temperature tendency term (EXTERNAL_FORCING_T).
1943    o pkg/seaice:
1944      - complete merge of ITD code into seaice_growth.F
1945        from MITgcm_contrib/torge/itd/code/
1946        no verification so far, but Torge Martin tested
1947        "1-D test case and Beaufort set up;
1948        deliver okay results after 1 model year."
1949      - complete merge of SEAICE_SIZE.h into all relevant routines
1950      - move computation of eta at Z-points into calc_viscosities
1951        + introduce global field etaZ
1952        + add different methods for computing etaZ, for now the old
1953          method (simple averages of eta to Z-points) is hardwired
1954        + replace etaMeanZ by etaZ in seaice_lsr, seaice_calc_residual,
1955          seaice_preconditioner
1956      - simplify computations for SEAICE_ZETA_SMOOTHREG
1957      - seaice_preconditioner:
1958        + replace one remaining press by pressLoc (mistake)
1959        + adjust printing of residuals
1960      - improve I/O of diagnostics of JFNK in seaice_jfnk.F:
1961        + add (SEAICE.h) and rename some counters (initiliased in
1962          seaice_init_fixed.F)
1963        + add _BEGIN/END_MASTER (myThid)  around print statements
1964        + print total number of iterations and failures over SEAICE_monFreq
1965          interval to STDOUT
1966      - move control over output-messages by fgmres to seaice_jfnk to save
1967        some operations
1968      - move resetting initial guess for fgmres outside of seaice_fgmres_driver
1969        in order to make restarts with sol .ne. zero (fgmres with restarts)
1970        (seaice_jfnk.F, seaice_fgmres.F)
1971      - seaice_calc_l/rhs.F: replace maskW/S by maskInW/S; this fixes
1972        a serious convergence problem when open boundaries are involved
1973    o pkg/ggl90: fix computation of control volumes for the case of
1974      ALLOW_GGL90_HORIZDIFF (probably not used very often): move control volumes
1975      up half a grid cell from C-centered to W-centered (pointed out by C. Eden)
1976    o pkg/seaice: simplify seaice_evp by avoiding use of extra fields u/vIceC
1977    o pkg/autodiff
1978      - Add inAdMode switch for SEAICEuseDYNAMICS:
1979        SEAICEuseDYNAMICSinAdMode
1980        (extend logic in ADAUTODIFF_INADMODE_SET)
1981    o pkg/seaice
1982      - Step 1 of merging ice-thickness distribution (ITD) code from
1983        MITgcm_contrib/torge/itd/ (author: Torge Martin)
1984        The code implements concept laid out in Thorndike et al. (1975);
1985        code is enabled via CPP flag SEAICE_ITD
1986        nITD (in SEAICE_SIZE.h) defines number of ice thickness categories;
1987        code is not complete yet!!
1988      - SEAICE_SIZE.h now included in almost all seaice routines
1989    o verification (using seaice):
1990      - switch back seaice-dynamics (+ lower SOLV_MAX_ITERS) in ADM exp.
1991        global_ocean.cs32x15.seaice ; update results.
1992      - compile B-grid dynamics in FW test exp 1D_ocean_ice_column ;
1993      - compile C-grid dynamics with #define SEAICE_ALLOW_JFNK in FW test exp
1994        offline_exf_seaice (previously compiling B-grid).
1995    o pkg/exf:
1996      - fix some STOP conditions in exf_check.F (from Aug 28, modifs did not allow
1997        to specify neither just 1 comp of wind or wind-stress, nor no surface momentum
1998        forcing): just replace CPP option ALLOW_ATM_WIND with run-time param useAtmWind.
1999    o pkg/layers (adjust changes from Sept 19):
2000      - do snap-shot output and fill diagnostics from inside iLa loop (layers_calc.F)
2001        this allows to remove "layers_maxNum" dimension from all layers arrays.
2002    o pkg/layers (adjust changes from Sept 19):
2003      - remove ALLOW_LAYERS_OUTPUT ; fix snap-shot and time-ave output ;
2004      - snap-shot extended to all type of layers (not just the 1rst type);
2005      - remove layers variables when corresponding CPP option is undef.
2006    o pkg/layers:
2007      - rename pkg/layers variable and add new output (layer exist & un-weighted
2008        velocity in layer)
2009    o pkg/seaice:
2010      - simplify (?) ocean-drag coefficent computations by using
2011        the same routine in all three solvers (saves some code lines)
2012      - remove global fields DRAGA and DRAGS from C-grid code and
2013        declare them locally in lsr.F (the only place where they are
2014        still used)
2015      - update AD output of lab_sea.evp (very sensitive anyway).
2016    o pkg/seaice: add Jacobian-free Newton Krylov solver for ice dynamics
2017      (Lemieux et al. 2010, 2012). Turn on with the usual SEAICE_ALLOW_JFNK
2018      and SEAICEuseJFNK=.true. A few things to note:
2019      - involves a FGMRES, that is parallel but very inefficient,
2020        because of many scalar products (global sums) in the Gram-Schmidt
2021        orthogonalization method. Needs to be replaced. Original code
2022        from J.-F. Lemieux
2023      - preconditioner for FGMRES is a stripped down version of LSOR
2024      - SOLV_MAX_ITERS is now used for LSOR as a solver and as a
2025        preconditioner. For the preconditioner, the default is set to 10.
2026      - Jacobian times vector is computed with finite differences
2027      - marginally related to JFNK-solver: add a smooth regularization for
2028        zeta with tanh that will improve convergence (Lemieux and Tremblay,
2029        2009) for any implicit solver (not implemented for EVP because EVP
2030        does not need this regularization in the first place). Define
2031        SEAICE_ZETA_SMOOTHREG in SEAICE_OPTIONS.h to use.
2032    o eesupp/src:
2033      - check in genmake2 that intrinsic S/R flush is available.
2034      - add S/R to flush IO unit (if intrinsic S/R flush is available)
2035      - flush standard & error msg unit before MPI termination
2036      - if debugMode, flush IO unit after printing msg
2037    o pkg/ctrl:
2038      - ctrl_unpack.F, ALLOW_GENARR3D_CONTROL code: fix missing argument in call
2039        to ctrl_set_unpack_xyz.
2040    
2041    checkpoint64 (2012/10/09)
2042    o pkg/shelfice
2043      - in mom_fluxform.F, mom_vecinv.F:
2044        CALL SHELFICE_V_DRAG(bi,bj,k,vFld,KE,KappaRU,vF,myThid)
2045        Bug fix KappaRU -> KappaRV
2046        does not change verification/isomip but may change other setups
2047        (presumably constant KappaRU=KappaRV)
2048      - fix diagnostics SHIU/Vdrag (thanks to Tom Millgate)
2049    o pkg/obcs:
2050      - fixed some indexing bugs in obcs_seaice_sponge.F
2051      - added obcs relaxation subroutines for HSALT and HSNOW
2052      - changes verification/seaice_obcs/results/obcs_seaice_sponge.F
2053    o pkg/seaice:
2054      - add "multicategory" parameterization for snow in analogy to ice,
2055        default is off for now.
2056    o pkg/obcs:
2057      - added obcs_seaice_sponge.F for obcs relaxation of seaice variables;
2058        see verification/seaice_obcs/input.seaiceSponge for example application.
2059      - remove local commom bloc "OBCS_GLOBAL" in obcs_readparms.F and do all the OB
2060        index setting by master-thread. This fix multi-threads Pb in previous modifs.
2061    o pkg/layers :
2062      - add diagnostics to pkg/layers
2063      - move the meat of pkg/layers from layers_calc.F to layers_fluxcalc.F
2064        (from R.Tulloch). Layers_calc.F now calls layers_fluxcalc.F accordingly.
2065    o pkg/generic_advdiff/gad_implicit_r.F :
2066      - fix ADVr diagnostics in case of both implicit vertical advection and diffusion.
2067    o pkg/seaice/seaice_growth.F:
2068      - fix SItflux diagnostics in virtual salt flux + balanceEmpmr case.
2069    o pkg/obcs:
2070      - change default setting of OBCS_UVICE_OLD from defined to undef;
2071      - use new parameter OB_indexNone for null index value (instead of hard-coded 0)
2072        in all pkg/obcs code and in other pkgs; remove k loop in obcs_check_depths.F;
2073      - pass OB_indexNone as (new) argument to S/R CTRL_MASK_SET_[X,Y]Z;
2074      - change OB null index value (OB_indexNone) to -99 ; this fix the problem
2075        with Southern & Western OB at a tile edge (at least in a simple set-up).
2076    o pkg/obcs:
2077      - change settings of OB index in case OB coincides with tile edge (shared by
2078        2 tiles), so that common OB location is registered by both tiles (instead of
2079        only 1). However, for Southern and Western OB, index value = 0 is not
2080        recognized as valid OB index (=default null value) and needs to be fixed.
2081      - modify accordingly OBCS_BALANCE_FLOW and OBCS_MONITOR (avoid double counting)
2082      - new parameter "OB_indexNone" for null index value (for now, still zero)
2083        to replace hard-coded null index value of zero.
2084    o pkg/exch2:
2085      - improve W2_USE_E2_SAFEMODE (faster) and W2_E2_DEBUG_ON:
2086        always check buffer-size (but outside the loop); move checking for valid
2087        index from W2_USE_E2_SAFEMODE to W2_E2_DEBUG_ON; in W2_E2_DEBUG_ON,
2088        print each tile and point connection only if |W2_printMsg|>= 2 and 3.
2089    o pkg/ctrl (pack & unpack):
2090      - in ctrl_pack.F & ctrl_unpack.F, use the same local file-name variable
2091        (locally defined) for different variables (+ remove the variable-specific
2092        file name in CTRL_GENARR.h). For now, only implemented for GENARR2/3D_CONTROL
2093        (to be extended to other local file names in ctrl.h).
2094    o pkg/flt:
2095      - add a FLT_Iter0 option (similar to PTRACERS_Iter0).
2096    o pkg/mdsio:
2097      - fix missing STOP in mdsio_readvec_loc.F (case ioUnit=0) when file is missing
2098    o tools/genmake2:
2099      - add similar dependences for target EXE_AD & EXE_FTL as we have for EXECUTABLE
2100        (added by Alistair in version 1.51 for building without make depend);
2101      - remove Header files list (H_SRC_FILES) from the dependence of targets
2102         ad_input_code.f & ftl_input_code.f (not clear why it was added in the first
2103        place in version 1.23): this save going through staf when unrelated header
2104        file has been modified.
2105       Note: for an intermediate target (e.g., ad_input_code.f or adtaf) without
2106        "make depend" step, still need to do "make links" before "make adtaf".
2107    o eesupp/src (+ few pkg src files) & genmake2:
2108      - finish to remove ALWAYS_USE_MPI in source code that TAF does not see;
2109      - no longer set ALWAYS_USE_MPI in Makefile (was done by genmake2).
2110      - improve genmake2 checking for ALLOW_${PKG} in CPP_OPTIONS.h files (distinguish
2111         upper/lower case ; account for space between "#" and undef/define)
2112    o pkg/flt (with exch2):
2113      - cleaning: fix so that it compiles; move remaining MPI calls out of flt_exch2.F;
2114      - simplify threads synchronisation; fix (many issues) multi-threaded with MPI.
2115    
2116    checkpoint63s (2012/09/05)
2117    o pkg/ecco:
2118      - remove #ifdef ALLOW_SMOOTH_CORREL3D brackets.
2119      - add more relevant #ifdef ALLOW_SMOOTH ones.
2120      - sort out useAtmWind, useSMOOTH, ctrlSmoothCorrel2D.
2121    o pkg/ctrl:
2122      - CTRL_OPTIONS.h : document CPPs related to smoothing; ALLOW_SMOOTH_CORREL2D/3D,
2123        ALLOW_CTRL_SMOOTH, ALLOW_SMOOTH_CTRL2D, ALLOW_SMOOTH_CTRL3D.
2124      - ctrl.h : document run time params doInitXX, doMainPack, doMainUnpack, doPackDiag,
2125        doSinglePrecTapelev (audodiff param!), ctrlSmoothCorrel2D (new) and
2126        ctrlSmoothCorrel3D (new).
2127        The added ctrlSmoothCorrel2D/3D replace the old ALLOW_SMOOTH_CORREL2D/3D CPP.
2128      - ctrl_readparms.F : initialise ctrlSmoothCorrel2D/3D and read from namelist.
2129      - ctrl_init.F ctrl_pack.F ctrl_unpack.F : switch off ustress/vstress
2130        controls when useAtmWind, and vice versa.
2131      - ctrl_map_ini_ecco.F : UVEL0, VVEL0, edtaux, edtauy cannot be smoothed as tracers.
2132      - ctrl_get_gen.F : replace #ifdef ALLOW_SMOOTH_CORREL2D with
2133          #ifdef ALLOW_SMOOTH, IF ctrlSmoothCorrel2D, IF useSMOOTH.
2134      - ctrl_map_ini_gen.F : replace #ifdef ALLOW_SMOOTH_CORREL3D with
2135          #ifdef ALLOW_SMOOTH, IF ctrlSmoothCorrel3D, IF useSMOOTH.
2136      - ctrl_set_pack_xy[z].F, ctrl_set_unpack_xy[z].F:
2137        replace ALLOW_SMOOTH_CORREL2D/3D brackets with ctrlSmoothCorrel2D/3D.
2138    o pkg/smooth:
2139      - remove un-necessary includes.
2140      - remove ALLOW_SMOOTH*D and ALLOW_SMOOTH_CORREL*D brakets.
2141        Those CPP options were never defined, and not necessary.
2142    o model/src:
2143      - fix CPP brackets in ini_mixing.F (GM_background_K belongs to gmredi).
2144      - standard treatment of useSMOOTH.
2145    o pkg/autodiff:
2146      - add LOGICAL useGGL90inAdMode, useGGL90inFwdMode, useSALT_PLUMEinAdMode,
2147        useSALT_PLUMEInFwdMode allowing to switch off ggl90 and salt_plume adjoint.
2148    o pkg/exch2:
2149      - add "if usingMPI" where it was missing (in exch2_rx?_cube*.template)
2150        + start to remove ALWAYS_USE_MPI in source code that TAF does not see.
2151      - make new S/R W2_MAP_PROCS out of w2_eeboot.F to setup exch2 CommonFlag
2152        and tiles to process mapping.
2153      - re-arrange 3 header files (W2_EXCH2_PARAMS.h, _BUFFER.h & _TOPOLOGY.h)
2154        moving /EXCH2_FILLVAL_RX/ & /W2_EXCH2_COMMFLAG/ to W2_EXCH2_TOPOLOGY.h;
2155        rename "exch2_tProc" to "W2_tileProc" and move seting of e2FillValue_RX
2156        from w2_eeboot.F to w2_readparms.F.
2157    o eesupp/src:
2158      - set exchNeedsMemsync & exchUsesBarrier according to "usingMPI" (instead of
2159        ALWAYS_USE_MPI) + moved from ini_communication_patterns.F to eeset_parms.F;
2160        also move setting of exchCollectStatistics from exch_init.F to eeset_parms.F
2161      - in eedie.F and all_proc_die.F, always call MPI_FINALIZE when ALLOW_USE_MPI
2162        is defined (remove condition on usingMPI) to match cases where MPI_INIT
2163        has been called.
2164      - fix bug I put in previous modif of exch_sm_3d_rx.template (not much used);
2165      - change default (non-MPI) value of myPid (from 1 to 0) to match MPI settings
2166        (so that on 1 proc, get same myPid independently of usingMPI)
2167      - add a stop if multi-procs but usingMPI=F ; stop also if usingMPI=T and
2168        useCubedSphereExchange with EXCH-1 (safer).
2169      - add "if usingMPI" where it was missing (+ start to remove ALWAYS_USE_MPI).
2170    o pkg/ggl90:
2171      - fix bug in filling corner mask array "mskCor" (FILL_CS_CORNER_TR_RL call)
2172        used in ALLOW_GGL90_SMOOTH code.
2173    o pkg/flt:
2174      - fix typo in FLT_WITHOUT_Y_PERIODICITY (the effect was to ignore stopping
2175        floats at the Southern end of the domain).
2176    o eesupp/inc:
2177      - add a list of CPP-options which can be set by Makefile (DEF_IN_MAKEFILE.h);
2178        but not used (and not to be used) anywhere, just for documentation.
2179    o pkg/autodiff, exf, ptracers & seaice (AD & TL output):
2180      - comment out the very nasty "writeBinaryPrec = writeStatePrec" line, since:
2181        a) can damage previously written records in any other multi-record files.
2182        b) if needed, can easily do it cleanly, by calling S/R WRITE_REC_3D_RL/S.
2183    o tools/genmake2:
2184      - define variable MAKE within Makefile and use it in place of 'make';
2185      - update AD_CONFIG.h (if needed) before building any of the executable
2186        (forward, adjoint or tangent-lin); this involves a 2nd invocation of make;
2187        and add the usual #ifndef/#define AD_CONFIG_H in AD_CONFIG.h;
2188      - always print usual warning comment 'this file is automatically generated'
2189        from script convert_cpp_cmd2defines (+ remove this warning from genmake2).
2190    o pkg/cheapaml:
2191      - updated to correspond to the code used in accepted paper (Nico Wienders).
2192    o pkg/exf:
2193        added run time switch useAtmWind to replace ALLOW_ATM_WIND cpp switch.
2194        ALLOW_ATM_WIND now just sets the useAtmWind default (see exf_readparms.F)
2195        and force defines ALLOW_BULKFORMULAE (EXF_OPTIONS.h).
2196    o pkg/exf, autodiff, ctrl, ecco and seaice:
2197        remove ALLOW_ATM_WIND brackets, or replace them with useAtmWind ones.
2198    o pkg/ctrl, ecco:
2199        allow to compile both ALLOW_U/VSTRESS_CONTROL and ALLOW_U/VWIND_CONTROL.
2200        Depending on useAtmWind, one is inactive, and the other is active (see
2201        exf_getffields.F/exf_getsurfacefluxes.F).
2202    o tools/genmake2:
2203      - improve error msg when failing in 2nd test of check_for_broken_Ff
2204      - fix option '-makefile' short-name (-mf according to genmake2 -help)
2205      - source local config file "genmake_local" just after processing the genmake2
2206        command arguments (previously done before processing arg).
2207    o pkg/grdchk:
2208      - add a call to TURNOFF_MODEL_IO for Tangent-Linear run (in this case, call
2209        to this routine from cost_final has been dropped in g_cost_final)
2210      - improve printed information (more explicit msg, no longer using "print *,"
2211         fix fcpertminus printed value).
2212    o model/src:
2213      - move call to COST_INIT_VARIA out of packages_init_variables.F directly
2214        into initialise_varia.F (just after calling PACKAGES_INIT_VARIABLES):
2215        this prevents getting cost-funct reset in adinitialise_varia recomputations.
2216    o pkg/dic:
2217      - move initialisation of "freefe" array from from dic_biotic_forcing.F to
2218        fe_chem.F: this prevents TAF from dropping this initialisation in TLM code.
2219    o pkg/grdchk:
2220      - grdchk_main.F : added CALL GLOBAL_SUM_INT( ierr , myThid )
2221      - grdchk_getadxx.F etc. : omit I/O if ierr.EQ.0
2222    o pkg/autodiff/ctrl/grdchk :
2223      - attempt to sort out what works and what does not,
2224        with regard to I/O, and to warn/stop accordingly.
2225    o pkg/grdchk:
2226      - attempt to fix grdchk in the case of useSingleCpuIO.
2227      - "if ( myProcId .EQ. grdchkwhichproc .AND. ierr .EQ. 0 )"
2228       statements were moved from grdchk_main.F and into
2229       grdchk_getadxx.F grdchk_getxx.F grdchk_setxx.F.
2230      - a global sum is applied to record numbers icvrec/layer
2231       out of grdchk_loc so that they be passed to I/O routines.
2232    o pkg/smooth:
2233      - fix recomputation that appeared with nlfs : use smooth_recip_hFacC,
2234        smooth_hFacW, smooth_hFacS (copied at init_fixed) in 3d case.
2235    o verification/testreport:
2236      - add option '-tlm' for Tangent-Linear test (-adm,-oad,-tlm are all exclusive);
2237      - can also use compressed (gzip) reference output file;
2238      - change format (in pkg/grdchk) of TLM output (+ add forward gradient)
2239        to be easier to collect by testreport.
2240      - update existing TLM output (half out-of-date by more than 3 yrs).
2241      - report NETCDF & LAPACK settings (from genmake2) in output dir.
2242      - report run-time in each individual summary (previously only for AD test);
2243        for TLM test, add also TAF version.
2244      - add daily TLM test on (old) aces cluster + weekly test on baudelaire.
2245    
2246    checkpoint63r (2012/08/15)
2247    o tools/genmake2:
2248      - fix Makefile for target ftlall (+ update files to clean after make ftlall)
2249    o pkg/ecco/ecco_cost_final.F :
2250      - fix fc print statements (to stdout and costfunction0000) so
2251        that the printed value is always after the global sum.
2252    o pkg/seaice/seaice_dynsolver.F :
2253      - fix ice strength assymptote at SEAICE_area_max<1
2254        (no change for the standard case of SEAICE_area_max=1)
2255    o some cleaning:
2256      - pkg source files: ensure that all *.F files from each pkg included the
2257        corresponding ${PKG}_OPTIONS.h file (except stand-alone src file which
2258        only includes CPP_EEOPTIONS.h); fix S/R CTRL_SMOOTH ; update AD experiment
2259        code_ad/*.F src files; add new option-file in pkg/admtlm + corresponding
2260        includes;
2261      - model/src: add PACKAGES_CONFIG.h wherever ALLOW_AUTODIFF[_TAMC] is used.
2262      - ALLOW_DIFFKR_CONTROL: add a stop in S/R CTRL_CHECK in case ALLOW_3D_DIFFKR
2263        is undef; also define /DYNVARS_DIFFKR/ common block in DYNVARS.h when
2264        ALLOW_DIFFKR_CONTROL is defined, to allow to compile and reach this stop.
2265      - update option-file CPP_OPTIONS.h of all AD experiments:
2266        * no longer include PACKAGES_CONFIG.h ;
2267        * includes ECCO_CPPOPTIONS.h if PACKAGES_CONFIG.h has been included ;
2268        * def/undef ALLOW_3D_DIFFKR independently of ALLOW_DIFFKR_CONTROL (before
2269          including ECCO_CPPOPTIONS.h).
2270    o pkg/cost, pkg/ctrl, pkg/ecco option-file:
2271      - clean-up and split content of old pkg/ecco/ECCO_CPPOPTIONS.h file into
2272        separated pkg option-file (done according to old doc from ECCO_CPPOPTIONS.h,
2273        not necessary accurate).
2274      - add a template for option-file ECCO_CPPOPTIONS.h, mostly empty, in
2275        pkg/autodiff, i.e., the 1rst pkg to compile for adjoint built, with lines to
2276        deliberately break compilation (a remainder that it needs to be customized)
2277      - in pkg/ecco, includes ECCO_OPTIONS.h instead of COST_OPTIONS.h
2278      - rename COST_CPPOPTIONS.h to COST_OPTIONS.h
2279      - rename CTRL_CPPOPTIONS.h to CTRL_OPTIONS.h
2280    o tools/genamke2:
2281      - check for lapack.
2282    o pkg/cost and pkg/ecco : attempt to sort out some of the limiting intricacies.
2283      - pkg/cost.cost_final.F : allow for use of pkg/ecco and pkg/cost cost functions
2284        jointly. The exclusive ifdefs were removed, to add costs terms (when defined)
2285        from both packages.
2286      - the fc global sum in pkg/ecco/ecco_cost_final.F was removed accordingly.
2287      - for objf_atl we use either the pkg/ecco or the pkg/cost term depending on CPPs.
2288      - pkg/ecco and model/src : add CPP brackets around pkg/cost and pkg/ctrl includes
2289        of "CTRL_SIZE.h" "ctrl.h" "ctrl_dummy.h" "optim.h" / "cost.h" accordingly.
2290    o pkg/cost : add comments to explain special and/or untested setups.
2291    o pkg/exf:
2292      - use EXF_OPTIONS.h to set pkg/exf options except if done in ECCO_CPPOPTIONS.h
2293        (previously, ALLOW_AUTODIFF_TAMC was controling this switch).
2294    o verification/*/code_ad:
2295      mimimal cleaning of AD experiments ECCO_CPPOPTIONS.h option-file:
2296      - reccord when this file is included (define ECCO_CPPOPTIONS_H)
2297      - remove the most obvious obsolete features (e.g., #define ALLOW_COST not
2298        allowed since Oct 2003 in any option-file except in PACKAGES_CONFIG.h)
2299    o pkg/seaice :
2300      - added possibility to change ice strength/PRESS0 relationship to
2301        HEFF, according to the following run time parameters
2302        SEAICEpresPow0 :: HEFF exponent for ice strength below SEAICEpresH0 (integer, >0)
2303        SEAICEpresPow1 :: HEFF exponent for ice strength above SEAICEpresH0 (integer, >0)
2304        SEAICEpresH0   :: HEFF threshold for ice strength            (m)
2305    o pkg/ggl90 :
2306      - added run time flag mxlSurfFlag to include the code that ensure
2307        mixing between first and second level (previously included as a comment)
2308    o verification/1D_ocean_ice_column/input_ad/data.autodiff :
2309      - add test of newly added dumpAdByRec=T option where
2310        we write all records to one file per variable.
2311    o verification/global_ocean.cs32x15/code_ad/CPP_OPTIONS.h :
2312      - switch to #define ALLOW_BALANCE_RELAX and ALLOW_BALANCE_FLUXES
2313        to check that this code is ok with taf and compiles in adjoint.
2314    o pkg/autodiff :
2315      - added run time param dumpAdByRec : ad dump format switch.
2316        If true then write all records to one file per variable.
2317        Else write one file per record (remains the default).
2318      - revise seaice_ad_dump.F and exf_adjoint_snapshots_ad.F accordingly.
2319    o pkg/seaice:
2320     - Added SEAICEuseTILT run time switch : if set to
2321       false then omit the tilt term in seaice dynamics.
2322     - Fix free drift calculation.
2323    o pkg/shelfice:
2324      When initializing SHELFICEDragQuadratic, set default to be
2325      consistent with shiCdrag in case SHELFICEuseGammaFrict is used,
2326      but retain option to set it independently
2327      (inconsistenty spotted by Veronique Dansereau)
2328    o eesupp/inc:
2329      - in EEPARAMS.h, add real-type constant for some frequently used simple number
2330         (0,1,2,1/2), with name explicitly referring to RS/RL type.
2331    o model/src:
2332      - move balancing of relaxation terms to new S/R balance_relax.F.
2333    o pkg/autodiff:
2334      re-write active I/O high-level (control) S/R:
2335      - rename  S/R ACTIVE_READ/WRITE_RL to ACTIVE_READ/WRITE_3D_RL
2336      - add 1 more argument (useCurrentDir) to replace the "_LOC" 2nd set of S/R.
2337      - use standard pkg/mdsio I/O routines (MDS_READ/WRITE_SEC_XZ/YZ  and
2338        MDS_READ/WRITE_FIELD); change loops to multi-threads.
2339      - update and merge active_file_control_slice.flow into active_file_control.flow
2340      - update the calls in lower level S/R (active_file.F, active_file_g.F and
2341        active_file_ad.F) keeping the argument list and function unchanged.
2342      - also update lower-level "_LOC" version (call same S/R with "useCurrentDir
2343        =.TRUE.") and remove high-level (control) _loc version (not called anymore).
2344      - new low-level active I/O routines, one for each type (RL/RS), for active var
2345        of various (XY,XZ,YZ) shape and level number (arguments: arrShape, myNr);
2346        fix ctrl_init_wet.F & ecco_cost_weights.F by calling the new S/R with the
2347        right type.
2348    o autodiff and RS=real*4:
2349      - call the right type (_RS instead of _RL) of S/R in few output S/R (pkg/exf
2350        ad-monitor and snapshots); disable arrType='RS' in mdsio_gl*.F ;
2351      - change argument type of 3-D mask argument to _RS to match type in the call
2352        (in seaice_cost*.F, ctrl_*_gen.F and *ctrl_bound.F); to be continued.
2353    o pkg/thsice:
2354      - re-anable balanceEmPmR when useSEAICE=T with useThSIce=T.
2355      - option to correct ocean fresh-water flux for imbalance of Atmos+Land
2356        fresh-water flux: uniform correction or proportional to local precip.
2357    o pkg/ctrl:
2358      - new header file CTRL_SIZE.h for parameters maxCtrlArr2D, maxCtrlArr3D
2359      - redefine CPP option ALLOW_BOTTOMDRAG_CONTROL to
2360                            ALLOW_BOTTOMDRAG_CONTROL_NONGENERIC
2361      - verification/hs94.1x64x5/ tests ALLOW_GENARR{2D,3D}_CONTROL
2362    
2363    checkpoint63q (2012/07/30)
2364    o pkg/autodiff:
2365      note about monitor and snap-shot of ad-variables:
2366      a) need to apply ADEXCH before monitor or output of ad-vars to include
2367       overlap contributions (was done for adjDump but missing for monitor).
2368      b) since ADEXCH implies adding overlap values to interior array, machine
2369       truncation error is expected when adding an ADEXCH call in the middle of
2370       the time-stepping (although mathematically identical).
2371      modifs:
2372      - fix some incorrect type (RL/RS, UV/scalar) in ADEXCH calls and ad-vars
2373        declaration (adEddyPsiX,adEddyPsiY in adcommon.h).
2374      - add new run-time params (dumpAdVarExch & mon_AdVarExch) to select how  to
2375        apply ADEXCH before monitor or snap-shot of ad-variables:
2376           =0 : no ADEXCH ; =1 : do ADEXCH ; =2 : apply ADEXCH on a local copy.
2377      - implement new method (copy+adexch) for snap-shot and monitor of main model
2378        ad-vars (initially not used by default -> output unchanged).
2379      - change default (set to 2) to use new method and update few output_adm.txt
2380        with accurate ad-monitor (global_ocean.90x40x15, tutorial_global_oce_biogeo
2381        and both tutorial_tracer_adjsens tests).
2382      - switch 2 global_ocean.cs32x15 AD-tests to AB-2 (seaice_dynmix & thsice)
2383        and turn off momDissip_In_AB in the 2 other (needed for stable AB-3).
2384    o pkg/ctrl:
2385      enable the use of a variable number (maxCtrlArr2D, maxCtrlArr3D) of
2386      generic control variables via
2387      #define ALLOW_GENARR2D_CONTROL and/or #define ALLOW_GENARR3D_CONTROL
2388      Only required customization should be S/R ctrl_map_ini_genarr.F
2389      (routine in repository contains example)
2390    o pkg/exf:
2391      - fix and refine checking of surface-relaxation setting when using EXF
2392    o verification (adjoint exp):
2393      - reduce length of simulation by half for experiment global_ocean.cs32x15
2394        (std, seaice & seaice_dynmix) and exp tutorial_dic_adjoffline; update output.
2395    o pkg/mom_common (mom_u/v_bottomdrag), pkg/shelfice (shelfice_u/v_drag)
2396      - replace if statements KE.ne.0 with KE.gt.0 to avoid sqrt of negative numbers
2397        of KE that can occur with aggressive optimization
2398      + put quadratic bottom drag calculation in separated loops (only done if
2399        using bottomDragQuadratic)
2400    o model/src: CG2D_NSA
2401      - clean-up:  stop if cg2dNormaliseRHS=T and AUTODIFF
2402         and replace GLOBAL_SUM calls with GLOBAL_SUM_TILE.
2403      - in test-exp that uses CG2D_NSA (bottom_ctrl & tutorial_tracer_adjsens),
2404         change cg2d residual target to be expressed in Wunits (=> do not normalise
2405         RHS ; this fix global_max Pb with TAF); update output.
2406    o verification/tutorial_tracer_adjsens:
2407       improve parameter consistency (and get rid of warnings):
2408       - use deltaTFreeSurf=deltaTtracer (better with NonLin FreeSurf);
2409       - switch Temp Adv Scheme from 81 to 80 (no limiter since theta < 0 is physical)
2410       - use staggerTimeStep (for stability) in som81; use default rotation period.
2411    o pkg/exch2:
2412      - with empty facet: fix compact-format (W2_mapIO=1) definition (was previously
2413        reset to 0 = 1 long line in X)
2414    o pkg/mdsio:
2415      - fix reading of dimensions from meta file for large-size domain
2416    o model/src:
2417      - fix saltIsActiveTr setting for IdealGas eosType (eosType is 6 character long);
2418      - to refine CS-grid check, add logical flag "hasWetCSCorners": true if using
2419        Cubed-Sphere Exch with CS-corners inside the domain;
2420        make new S/R INI_GLOBAL_DOMAIN from code in ini_linear_phisurf.F to calculate
2421        globalArea and to set hasWetCSCorners.
2422      - add warning if usingCurvilinearGrid and momAdvection in flux-form (missing
2423        metric terms); stop if hasWetCSCorners=T and momAdvection in flux-form.
2424      - re-activate the stop if useCDscheme and hasWetCSCorners=T (previously if
2425        useCDscheme and useCubedSphereExchange).
2426    o pkg/seaice/seaice_growth.F :
2427      - compute the SEAICE_DISABLE_HEATCONSFIX term accordingly
2428        for the (.NOT.useRealFreshWaterFlux).OR.(nonlinFreeSurf.EQ.0)
2429        when the previous code was not correct.
2430      - in all cases diagnoze the boundary condition mismatch to SIaaflux
2431      - in the case of useRealFreshWaterFlux.AND.(nonlinFreeSurf.GT.0) add
2432        that term to QNET (essentially to set the melt/freeze water to 0degC).
2433        when SEAICEheatConsFix is true, so that the ocean+ice budget heat is closed.
2434    o verification/global_ocean.cs32x15/input.seaice :
2435      - add SEAICEheatConsFix in data.seaice, ensuring closed ocean+ice heat budget.
2436      - add diagnostics (commented out) for budget test using my matlab codes (gcmfaces).
2437      - update results (output.seaice.txt) accordingly.
2438    o verification/lab_sea/input/data.seaice :
2439      - remove SEAICEheatConsFix, which is now be tested
2440        in global_ocean.cs32x15. The presently coded fix
2441        is only consistent with real fresh water + nlfs.
2442      - update results (output.txt) accordingly.
2443    o pkg/salt_plume: added diagnotic for salt tendency (oceSPtnd).
2444    o AD_CONFIG.h file:
2445      - in genmake2: remove "#undef ALLOW_ECCO_OPTIMIZATION" from AD_CONFIG.h;
2446      - remove #include "AD_CONFIG.h" from all included OPTIONS files and
2447        add it explicitly in each fortran src file where it is needed.
2448        motivation: header file AD_CONFIG.h is generated/modified after "make depend"
2449        thus introducing potentially wrong dependency; therefore, better to include
2450        it only where it's really needed, and after any other included OPTIONS file
2451        (less tempting to bring conditional includes according to ALLOW_ADJOINT_RUN
2452        or ALLOW_TANGENTLINEAR_RUN).
2453    
2454    checkpoint63p (2012/07/06)
2455    o pkg/autodiff:
2456      - rename S/R INI_AUTODIFF to AUTODIFF_INIT_VARIA ;
2457      - create new header file "AUTODIFF_PARAMS.h" for pkg/autodiff parameters
2458        which are now read from new parameter file "data.autodiff" (inAdExact
2459        previously in "data", use{KPP/GMRedi/SEAICE}inAdMode previously in data.pkg)
2460      - add file "data.autodiff" in all verification/*/input_ad/ directories.
2461      - add run-time parameter to turn On/Off SEAICEuseFREEDRIFT in adjoint/forward
2462        mode (used in global_ocean.cs32x15.seaice_dynmix test exp.)
2463    o verification/tutorial_tracer_adjsens/
2464      - add extra sub-verification which uses "SOM" advection scheme
2465        (2nd Order-Moment Advection Scheme, Prather Limiter) with
2466          #define GAD_ALLOW_TS_SOM_ADV in GAD_OPTIONS.h
2467        and in data:
2468          multiDimAdvection=.TRUE.,
2469          tempAdvScheme=81,
2470          saltAdvScheme=81,
2471    o model/src:
2472      - introduce ALLOW_BALANCE_RELAX which allow the removal
2473       of the global mean of relaxation terms by setting
2474       balanceThetaClimRelax and balanceSaltClimRelax
2475      - disable balanceEmPmR and balanceQnet in the case when useSeaice.
2476       This case is now treated appropriately in seaice_growth.F
2477    o pkg/seaice:
2478      - do balanceEmPmR and balanceQnet based on the net fluxes
2479        (SItflux) that enter the ocean+ice system rather than QNET
2480        and EMPMR. Works best in real fresh water.
2481      - SIatmFW, SIatmQnet, and SItflux computations had to be moved
2482        out of the diagnotics bloc, and stored in global arrays.
2483    
2484    checkpoint63o (2012/06/29)
2485    o vertical mixing schemes:
2486      - remove unused S/R CALC_BUOYANCY (left from branch-atmos merging)
2487      - replace computation of density (in Function STATE1, opps_calc.F) by a call
2488        to S/R FIND_RHO_SCALAR
2489      - pass sigmaR to S/R PP81_CALC, MY82_CALC (but not yet used) and to GGL90_CALC
2490        and use it for N^2 calculation in ggl90_calc.F (save 2 density computations);
2491        affects output (vermix.ggl90) at truncation level.
2492    o testreport:
2493      - change adjustment of SIZE.h for mpi+mth testing: preserve enough tiles
2494        (nSx,nSy) for the number of threads (from eedata.mth)
2495    o model/src:
2496      - remove 2nd set of calls at the top of initialise_varia.F (Adjoint part)
2497        related to Non_Lin Free-Surf or Bottom-Control (but not longer necessary).
2498    o verification/tutorial_tracer_adjsens/
2499      - compile with ALLOW_CG2D_NSA
2500      - run with nonlinFreeSurf=3
2501      - update reference output_adm.txt
2502    o tools/genmake2:
2503      - add "-DHAVE_NETCDF" to the DEFINES list when NetCDF is available ;
2504        refine usePROFILES switching off (only when NetCDF is not available).
2505    o verification (atmospheric set-up):
2506      - change eosType='IDEALGAS' to eosType='IDEALG' to match variable declaration
2507    o pkg/profiles : refine profiles and files handling.
2508    o model/src and pkg/ecco : introduce run-time switch usePROFILES.
2509    o model/src/the_main_loop.F, forward_step.F and pkg/exf/EXF_OPTIONS.h :
2510      - changes to use model/src/the_main_loop.F rather than the ecco version
2511        in ecco type adjoint runs.
2512    o model/src:
2513      - move computation of recip of grid distance & area from INI_MASKS_ETC to INI_GRID
2514      - move setting of h0Fac[C,W,S] from INI_LINEAR_PHISURF to INI_MASKS_ETC
2515      - update_masks_etc.F: rename SMOOTH*_R4,R8 function to the corresponding type (RS,RL)
2516    o model/src:
2517      - fix S/R UPDATE_CG2D for ALLOW_DEPTH_CONTROL case (was empty before);
2518        update output of test experiment bottom_ctrl_5x5.
2519    o pkg/generic_advdiff:
2520      - implement vertical bi-harmonic diffusion (for now, only for T & S and
2521        only explicitly).
2522    o verification/bottom_ctrl_5x5/
2523      update reference output (results changed quite some time ago,
2524      not sure when; but new reference results look ok in terms of grdchk)
2525    o verification/1D_ocean_ice_column/
2526      For verification purposes, the exact adjoint rather than an approx.
2527      should be used (e.g., to comare against F.D. or TLM).
2528      removed autodiff_inadmode*_ad.F routines in code_ad/
2529      Update results/ accordingly.
2530    o pkg/cal:
2531      - change cal_getdate.F so that output date is function of input time only
2532        (less ambiguous, not mixed up with input iteration number).
2533      - fix calendarDumps for non-zero phase-lag (S/R CAL_TIME2DUMP).
2534    o pkg/diagnostics:
2535      - implement calendarDumps also for stats-diags
2536      - implement calendarDumps also for snap-shot output (negative freq)
2537      - for now, ignores calendarDumps if non-zero phase-lag.
2538    
2539    checkpoint63n (2012/06/04)
2540    o model/src:
2541      - recompute rSurfW & S to ensure consistent column thickness (needed for rStar)
2542        between Sum_k(hFac*drF) and rSurf-rLow, for now only when using pkg/shelfice;
2543      - use h0FacC, W & S to compute hFac_surfC, W & S in calc_surf_dr.F (more
2544        similar to calc_r_star.F); update results of experiment internal_wave and
2545        tutorial_global_oce_in_p (affected @ truncation level).
2546    o pkg/shelfice:
2547      - add parameterisation of advective-diffusive flux into the ice shelf
2548        according to Holland and Jenkins (1999), eq.22-33, as suggested by Jan De Ryd
2549      - simply eps3/3a computation
2550    o eesupp:
2551     - add new CPP option (DISCONNECTED_TILES) to disconnect tiles (no exchange
2552       between tiles, just fill-in edges assuming locally periodic subdomain) and
2553       add corresponding exchange subroutines (EXCH0);
2554     - new CG-solver version (_EX0) for disconnected-tiles special case.
2555    o model/src (CG-solvers):
2556     - modify Single-Reduction version (CG2D_SR) in case cg2dMaxIters is reached
2557       (similar final residual output and max-Iter number as with standard version);
2558     - allows to store and use lowest-residual solution (standard & _SR versions);
2559     - cleaning up (remove old, commented out code, LETS_MAKE_JAM ...).
2560     - by default, also compile CG2D_SR version (define ALLOW_SRCG in CPP_OPTIONS.h)
2561    o eesup/src:
2562     - global_vec_sum.F cleaning: add a BARRIER ; update comments ; remove ndef
2563       ALWAYS_USE_MPI (no longer needed after fixing usingMPI settings - March 2012)
2564    o pkg/salt_plume added to lab_sea/input_ad.noseaicedyn
2565    
2566    checkpoint63m (2012/04/27)
2567    o pkg/shelfice:
2568     - account for partical cells in surface level below ice-shelf for hydrostatic
2569       pressure calculion (set uniformFreeSurfLev to F); update isomip experiments.
2570    o ad test experiments:
2571     - update and rename to "ad_optfile.local" local AD-optfile specific to a
2572       particular adjoint verification experiment (in verification/*/code_ad/)
2573    o pkg/seaice & pkg/exf:
2574     - Part two of ECCO-CLIVAR code merges.
2575       Completes merge of seaice area relax. code.
2576       Requires unified CPP option EXF_ALLOW_SEAICE_RELAX
2577       to be set in EXF_OPTIONS.h since this pkg controls its I/O
2578       (and avoids second CPP option in SEAICE_OPTIONS.h)
2579     - change default value of costIceStart & costIceEnd to a valid date.
2580     - add snowPrecip to HSNOW in seaice_growth
2581    o pkg/ptracers:
2582     - move ptracers summary and setup check into separated S/R ; add a check for
2583       valid PTRACERS_Iter0 value (error+stop or just warning).
2584    o pkg/cal (+ pkg/ecco):
2585     - avoid calling a S/R with 2 times the same arg (FWD: unless both are only used
2586       as input; and for AD, unless both are not differentiable (e.g., k index)).
2587    o model/src:
2588     - define internal flag "uniformFreeSurfLev" (=T when free-surface level-index
2589       is everywhere k=1) to speed-up some calculations (by pass kSurf reference);
2590       temporary set to usingZCoords value (to be changed to F when using shelfice).
2591     - hydrostatic pressure: implement partial cell near the surface also for
2592       Z-coordinates (for the case where uniformFreeSurfLev=F); replace test on
2593       usingZCoords with test on uniformFreeSurfLev where needed (in NonHyd code).
2594    o pkg/ctrl/ctrl_init.F:
2595     - add a formal parameter to s/r ctrl_init_rec to print
2596       xx_$(ctrl_valiable)_file for easier debugging
2597     - move call of cal_* routines into the if-block where they are really
2598       needed so that xx_$(ctrl_variable)_period can be 0 or -12 without having
2599       to specify a startdate
2600    o pkg/seaice:
2601     - update comments in SEAICE_OPTIONS.h (+ similar update of lab_sea/code and
2602       global_ocean.cs32x15/code versions).
2603     - turn on seaice Multi-category (in data.seaice, SEAICE_multDim=7) for
2604       verification experiment global_ocean.cs32x15.seaice and update results.
2605    o pkg/exf:
2606     - new S/R EXF_GETFIELD_START to return starting-time of a forcing field
2607       (according to useExfYearlyFields).
2608    o pkg/cal:
2609     - move calendar setting & summary (previously in cal_readparams.F) into new
2610       S/R CAL_INIT_FIXED to be called later in the initialisation process, once
2611       length of the simulation is set (after SET_PARMS call); This is an attempt
2612       to fix Pb when, e.g.: pkg/longstep, modifies the length of the run.
2613     - For safety: keep a record of pkg/cal parameter settings status
2614               to allow to STOP if one pkg/cal S/R is called too early.
2615     - add a stop in all basic pkg/cal subroutines if called before setting is done.
2616     - modify cal_getdate.F: stop when nothing was returned;
2617       if called with myIter=-1, simply retrun modelBaseDate (1,2 = startDate_1,_2);
2618       this allows to remove "cal.h" from seaice_read_parms.F & init_mnc_vars.F.
2619    
2620    checkpoint63l (2012/04/04)
2621    o pkg/bbl:
2622      - fix call to FIND_RHO_2D in bbl_calc_rho.F (case multi-tiles per proc);
2623        update global_with_exf output.yearly.txt file.
2624    o pkg/cal:
2625      - start to clean-up cal_set.F ; fix for the case where baseTime is non-zero.
2626      - remove 2 unsused and very short (1 line only) functions ;
2627      - remove unsused subroutines from AD-Diff list.
2628    o model/src:
2629      - start to implement clean wait to stop in initialization S/R (config_check.F,
2630         packages_check.F, ini_parms.F and pkg/obcs/obcs_check.F + pkg/mypackage)
2631    o folowing PRINT_MESSAGE changes:
2632      - remove reminder multiple print to the same file (STDOUT) when multi-threads.
2633    o pkg/bbl:
2634      - modification so it can work with z*
2635      - replace deltaT with dTtracerLev(k) for asynchronous time stepping
2636      - global_with_exf/input.yearly verification; changes output.yearly.txt
2637    o eesupp/src:
2638      - PRINT_MESSAGE: use OpenMP critical instruction (similar to PRINT_ERROR);
2639        writing to unit 0 (if unit=errorMessageUnit) extended to the case myThid=1
2640      - CHECK_THREADS: specific code if using OpenMP threading: improve checking of
2641        # of threads across processors (e.g., different env OMP_NUM_THREADS setting)
2642      - improve special preliminary call to EESET_PARMS (if eedata is read 2 times).
2643      - when using MPI, always set usingMPI=T ; set default accordingly and stop
2644        if not consistent.
2645      - ALL_PROC_DIE: add a BARRIER after MPI_FINALIZE call ; skip this when thread
2646        argument is zero (in case called within single-thread section).
2647    o pkg/fizhi:
2648        clean-up turbulence cold-start switch: decided in fizhi_init_vars.F, stored
2649        in common bloc (fizhi_coms.h) and then passed as argument up to S/R TURBIO.
2650    o pkg/exch2:
2651      - add argument "updateCorners" to S/R exch2_get_uv_bounds (enable to
2652        activate EXCH_IGNORE_CORNERS in vector EXCH S/R).
2653      - switch 1rst EXCH call to IGNORE_CORNERS (instead of UPDATE_CORNERS)
2654        but keep the 2nd with UPDATE_CORNERS: this prevents overwriting good data
2655        with bad ones coming from a not-yet-updated halo.
2656        This should fix the problem when sNx <> sNy and GCD(sNx,sNy) < 2*Olx.
2657    o pkg/frazil:
2658        move FrzForcT diag from frazil_diagnostics_state.F to frazil_calc_rhs.F
2659        http://mitgcm.org/pipermail/mitgcm-devel/2012-March/005384.html
2660    o model/src/config_check.F: add a check for OLx>sNx/OLy>sNy
2661    o verification/lab_sea
2662      * #undef SEAICE_EXCLUDE_FOR_EXACT_AD_TESTING
2663      * #define ALLOW_SST_CONTROL & ALLOW_SST_CONTROL
2664      * nTimeSteps 3 -> 4
2665      * changed reference output accordingly
2666    o pkg/ctrl:
2667      * fix ctrl_get_gen for xx_sst, xx_sss
2668    o pkg/fizhi:
2669      - fix 2 calls to S/R GRD2MSC (argument igrd) in update_earth_exports.F
2670        update results of exp. fizhi-cs-32x32x40 (fail with only 6 digits for cg2d)
2671      - by default, use new version of S/R GETPWHERE (#define TRY_NEW_GETPWHERE);
2672        fix few out-of-bounds indices in referencing vars (initialise igrd to 1);
2673        clean-up fizhi_turb.F (remove unused & uninitialised qdiaglsm array).
2674    o pkg/gmredi:
2675      - add diagnostic of Redi (main diagnonal) vertical diffusive flux of Temp
2676    o pkg/fizhi:
2677      - fix few initialisation and multi-tile Pb: aqualev & gridalt now pass the
2678        (old)aces open64 tuv test.
2679    o pkg/icefront: fix bug and reorder loop in icefront_init_varia.F
2680    o pkg/mom_vecinv:
2681      - fix 1 loop range in mom_vecinv.F to be like all the other loops which
2682        set/update gu,gv/Diss (fix Pb of uninitialised fVerUkp in admom_vecinv
2683        with non-lin free-surf).
2684    o model/src: move k-loop outside of i/j-loops when (re-)computing R_low
2685      in ini/update_masks_etc.F in order to avoid -O3 optimization problems with
2686      some compilers (gfortran 4.6.0 on MacOS)
2687    o momentum:
2688      - separate fVer?(:,:,kUp) & fVer?(:,:,kDown) in argument list of MOM_FLUXFORM
2689        & MOM_VECINV subroutines (to help TAF). This fixes Pb of uninitialised
2690        fVer?(kUp) in admom_fluxform with non-lin free-surf or bottom control.
2691    
2692    checkpoint63k (2012/03/17)
2693    o model/src:
2694       - selectAddFluid (ALLOW_ADDFLUID): add missing term in horizontal momentum
2695         flux-form (mom_fluxform.F) and vertical momentum (calc_gw.F) equations.
2696       - SOLVE_DIAGONAL: switch default to use adjoinable & vectorized version
2697         (#undef SOLVE_DIAGONAL_LOWMEMORY); update output of exp. front_relax.bvp.
2698    o model/src: solve_*diagonal.F
2699       - replace division with multiplication by inverse (similar to original version)
2700         update output of AD exp. global_ocean.90x40x15.
2701       - fix pkg/gmredi/gmredi_calc_psi_bvp.F & pkg/ggl90/ggl90_calc.F
2702         to enable the use of the vectorized & differentiable solve_tridiagonal.F
2703       - test exp. global_ocean.90x40x15/input_ad: switch to advection scheme 20 for
2704         vertical advection (to get solve_tridiagonal tested in AD mode).
2705    o pkg/seaice: ECCO-CLIVAR merge:
2706      1. seaice AREA relaxation
2707         * CPP option: SEAICE_ALLOW_AREA_RELAXATION
2708         * runtime flag: SEAICE_tauAreaObsRelax
2709      2. modified global mean cost imbalance code: CPP option
2710          ALLOW_SSH_GLOBMEAN_COST_CONTRIBUTION
2711    o another iteration on solve_*diagonal.F
2712       Make choices independent of AUTODIFF
2713       Default will be the adjoinable vectorized version.
2714       Alternative choices are:
2715       * non-adjoinable original version with low memory footprint:
2716         #define SOLVE_DIAGONAL_LOWMEMORY
2717       * still adjoinable but does not vectorize (k as inner-most loop):
2718         #define SOLVE_DIAGONAL_KINNER (keeping SOLVE_DIAGONAL_LOWMEMORY undef)
2719    o testreport
2720     - add option to use a home made wrapper around "make"
2721     - remove MITGCM_IEEE env. variable (no longer active)
2722    o pkg/shelfice
2723     - improve computation of friction velocity for velocity dependent
2724       exchange coefficients: include velocities into SHELFICEBoundaryLayer
2725       block to average velocities vertically
2726     - add TAF store directives for SHI_ALLOW_GAMMAFRICT
2727    o Modify diagonal solvers, now three versions (upon request):
2728      #ifndef SOLVE_DIAGONAL_AUTODIFF
2729        1. default version (dating back a while ago)
2730      #else /* def SOLVE_DIAGONAL_AUTODIFF */
2731      # ifdef SOLVE_DIAGONAL_KINNER
2732        2. adjoinable version with k-innermost loop (G. Forget)
2733      # else
2734        3. adjoinable vectorized version of 2.
2735      # endif
2736      #endif /* SOLVE_DIAGONAL_AUTODIFF */
2737      All flags are currently set within routines, but could/should be moved to CPP-options.
2738      Array bounds for 1. are as before, for 2.,3. cover the entire domain
2739      (could be changed for 1. too).
2740    o verification/lab_sea (fwd):
2741      - update the 4 fwd lab_sea test experiment: no longer SEAICE_GROWTH_LEGACY,
2742        use 7 categories (except hb87), new solve4temp params (except salt_plume),
2743        constant salinity (=4) or variable salinity (salt_plume) done through
2744        SItracer.
2745    o pkg/seaice:
2746      - rename parameters: SIsalFrac to SEAICE_saltFrac & SIsal0 to SEAICE_salt0;
2747      - remove old parameters ( SEAICE_freeze, SEAICEturbFluxFormula, SEAICE_gamma_t,
2748         SEAICE_gamma_t_frz, SEAICE_availHeatTaper & SEAICE_availHeatFracFrz)
2749        from SEAICE_PARMS.h ; still need to fix seaice_cost_sst.F (broken when
2750        SEAICE_freeze got retired) but already better than previously with
2751        SEAICE_freeze=123456.7 deg.C;
2752      - move setting of facOpenGrow/Melt from SEAICE_INIT_FIXED to SEAICE_READPARMS
2753        (safer multi-threaded setting); always set SEAICEuseEVP;
2754      - setting of ocean-ice turb. flux coeff: moved from SEAICE_CHECK to
2755        SEAICE_READPARMS & SEAICE_INIT_FIXED (this fixes wrong summary report);
2756        stop if multiple specifications for the same coeff; make sure default
2757        SEAICE_mcPheePiston is compatible with drF(1) & deltaT.
2758    o pkg/obcs:
2759      - allow to switch to upwind 1rst order advection scheme for the advective
2760        flux computation at the open-boundary; disabled for adjoint built.
2761    o pkg/ptracers:
2762      - rename PTRACERS_RESTART.h -> PTRACERS_START.h
2763      - rename ptracers_fields_blocking_exchanges.F -> ptracers_fields_blocking_exch.F
2764      - add parameter to decide when to start a tracer; use internal flag to
2765        know which tracer to step-forward; switch this internal flag at the top
2766        of forward_step.F (new S/R PTRACERS_SWITCH_ONOFF); for now, not enabled
2767        for adjoint built.
2768    o pkg/seaice:
2769      - add SEAICE_SIZE.h anywhere in the code where SEAICE.h is included ;
2770      - move MULTDIM declaration and setting from SEAICE.h to SEAICE_SIZE.h ;
2771      - keep experiment offline_exf_seaice truly single category (set MULTDIM=1).
2772    o pkg/ecco:
2773      - fix writing of output file DiagnosCost_ClimSalt/Theta
2774        and DiagnosCost_DriftSalt/Theta (if multi-tiles per proc).
2775    o pkg/seaice:
2776      - add missing initialisation of COR_ICE array in dynsolver.F
2777      - merging SEAICE_MULTICATEGORY define and undef cases. Now the same code is
2778        compiled either way, and is tested in all exps (multidim was only tested
2779        in lab_sea ad before).
2780      - cosmetic change to prepare for future addition of ITD. no change to results.
2781        no defaults change.
2782      - added run time param SEAICE_multDim (7 for SEAICE_MULTICATEGORY, 1 otherwise).
2783      - by lack of adequate verification experiments, I further used custom versions
2784        of global_ocean.cs32x15 to test multicat or not, with pickup or not. All
2785        should be correct.
2786      - avoid recomputations in ad.
2787    o array initialisation in adjoint mode:
2788      1) pkg/mom_common/mom_calc_ke.F:
2789        add full array initialisation of KE inside mom_calc_ke.F (ALLOW_AUTODIFF_TAMC):
2790        The S/R which calls MOM_CALC_KE initialises KE but in some recomputation
2791        part this initialisation is gone, resulting in Floating Point Exception
2792        (caught by open64 compiler with debug option).
2793      2) model/src/convective_weights.F
2794        set output convectCount over the full array range (instead of doing
2795        an update): this fix a similar issue when called within recomputation (adjoint)
2796        which could by-pass the initialisation (normally done in the caller S/R).
2797    o pkg/seaice:
2798      - final version of turbulent flux params, as agreed at MIT ice meet:
2799           SEAICE_mcPheePiston (default is ~ 0.000875)
2800           SEAICE_mcPheeTaper (default is 0.)
2801           SEAICE_frazilFrac (defualt is 1.)
2802           SEAICE_mcPheeStepFunc (default is false)
2803      - changes results at trunction error level
2804      - ifdef SEAICE_EXTERNAL_FLUXES, disallow SEAICE_waterAlbedo
2805    o added pkg/frazil:
2806      - see frazil_description.tex for details
2807      - verification experiment is global_with_exf/input.yearly; changes output.yearly.txt
2808    o pkg/shelfice/shelfice_thermodynamics.F
2809      - fix exponents for velocity dependent exchange coefficients: change
2810        from 2/3(=0) to 0.66666666666666667
2811      - move computation of velocity dependent exchange coefficients into
2812        separate loop, so that it applies to both thermodynamics
2813      - move some divisions by constants out of loops
2814    
2815    checkpoint63j (2012/02/16)
2816    o pkg/seaice:
2817      - overhaul of seaice_summary.F after feb 2012 clean-up of seaice_growth.F etc.
2818      - SItracer:  added run time params, and allow coupling to ocn salinity.
2819    o pkg/seaice: remove (almost) all divisions by constants within loops
2820      in seaice_growth.F and seaice_solve4temp.F, this changes (only) the cg2d
2821      results of global_ocean.cs32x15.seaice from 16 to 11 digits (but only
2822      those, caused by 1/QI -> recip_QI) -> update output.seaice.txt,
2823      output_adm.seaice_dynmix.txt and also lab_sea: output_adm.evp.txt
2824    o pkg/seaice :
2825      - simplify McPhee tapering, and allow to use it with SEAICEturbFluxFormula
2826        = 1 or 2, using newly added run time parameter SEAICE_availHeatTaper.
2827      - fix d_AREAbyATM, d_AREAbyOCN, d_AREAbyICE diags I broke in r1.148.
2828      - add permanent SItflux diag that corresponds to TFLUX but includes
2829        ice+snow. Hence SItflux-TFLUX should match the ice+snow heat budget.
2830      - allow activation/testing of a fix for suspected missing term in
2831        ocn-ice heat budget (to be confirmed). To test this, you want to
2832        undef SEAICE_DISABLE_HEATCONSFIX, and then set the run time param
2833        SEAICEheatConsFix to .TRUE. that also allows the 'SIaaflux' diagnostic.
2834      - no change in results, fwd or ad.
2835    o global_ocean.cs32x15/results: 3 changes following from the pkg/seaice commit below:
2836      - switch to variable freezing point.
2837           Results change : cg2d -> 1 digits; ad -> 3-6-6 digits.
2838      - bug fix : the sublimation term that was missing is now activated.
2839           Results change : cg2d -> 2 digits; ad -> 8-6-6 digits.
2840      - bug fix : flooding sign term for SIsal0.NE.0.
2841           Result change : cg2d -> 8 digits; ad -> 11-12-9 digits.
2842    o pkg/seaice:
2843      - unified freezing point treatment : the old SEAICE_VARIABLE_FREEZING_POINT
2844        is now the default, and the old default constant freezing point is recovered
2845        with SEAICE_tempFrz0    = -1.96,
2846             SEAICE_dTempFrz_dS = 0.,
2847      - retire SEAICE_freeze (= the old way of specifycing the constant freezing point)
2848      - remove ALLOW_SEAICE_FLOODING brackets; run time switch is already there.
2849      - bug fix (thanks to M. Losch) : the sublimation term that was missing is now
2850        activated. To reproduce old results with this bug define SEAICE_DISABLE_SUBLIM.
2851      - bug fix (silly me) : flooding sign term (seaice_growth.F r 1.149line 1211)
2852        was wrong for SIsal0.NE.0. Changes cs32x15 results (see above item for detail).
2853      - bug fix (thanks to O. Jahn) : area loss for melting  got messed up in
2854        seaice_growth r149 for legacy branch (no results change).
2855      - introduce SEAICE_CAP_SUBLIM : caps sublimation heat flux in solve4temp (code
2856        from I. Fenty).
2857      - results did not change except for global_ocean.cs32x15, mostly due to the
2858        switch to variable freezing point (see above item for detail).
2859    o pkg/thsice:
2860      - fix and simplify interface to salt_plume pkg ; diagnose directly amount of
2861        seawater freezing in thsice_calc_thickn (not used).
2862    o pkg/seaice: turbulent flux term specification via run time params.
2863      - replace CPP switches with run time switches to facilitate testing
2864      - retired CPPs : MCPHEE_OCEAN_ICE_HEAT_FLUX,
2865                       GRADIENT_MIXED_LAYER_TURBULENCE_FACTOR
2866      - added runtime parameter : SEAICEturbFluxFormula
2867      - move Mcphee constants to SEAICE_PARAMS.h
2868      - seaice_readparms.F : read turbulent flux term params (SEAICEturbFluxFormula;
2869                 SEAICE_availHeatFrac/Frz, or SEAICE_gamma_t/_frz if apply);
2870                 remove seaice_summary call (moved to seaice_init_fixed)
2871      - seaice_init_fixed.F : set SEAICE_availHeatFrac/Frz depending on
2872        SEAICEturbFluxFormula, and seaice_summary call (moved from seaice_readparms)
2873      - seaice_summary.F : add missing report of read turbulent flux term set up
2874                           and SITRACER.
2875      - seaice_check.F : check range; inform and stop if retired CPPs are used
2876                         (incl. SEAICE_AGE).
2877      - seaice_growth.F : unified use of SEAICE_availHeatFrac/Frz, without
2878             CPP switch, same computation as before for the different options.
2879      - change results at the truncation level.
2880    o pkg/seaice:
2881      - remove un-used parameters LAD & MAX_TICE ; add new run-time parameters:
2882        useMaykutSatVapPoly (default=F), postSolvTempIter (default=2) and
2883        SEAICE_wetAlbTemp (default=-1e-3). Remove option SEAICE_SOLVE4TEMP_LEGACY.
2884      - update verification/*/input*/data.seaice:
2885        to reproduce previous results with former #defined SEAICE_SOLVE4TEMP_LEGACY
2886        code, set useMaykutSatVapPoly=T & postSolvTempIter=0 ;
2887        and to reproduce previous results with former non-SOLVE4TEMP_LEGACY code,
2888        set SEAICE_wetAlbTemp=0 & SEAICE_snowThick=0.
2889    o pkg/seaice/seaice_solve4temp.F (SOLVE4TEMP_LEGACY):
2890      - remove LEGACY code for solving for tsurf (A1,A2,A3) but maintain the same
2891        algorithm (same choice: useMaykutPolySatVap=T, postSolvTempIter=0);
2892        difference in results only due to machine truncation.
2893      - remove MAX_TICE (tsurf is always =< TMELT anyway); keep MIN_TICE if using
2894        MaykutPolySatVap; keep MIN_LWDOWN.
2895      - adapt SEAICE_MODIFY_GROWTH_ADJ code (untested) to non-legacy formulation.
2896      - update output of verification exp. lab_sea (4 fwd: 11 cg2d digits except hb87,
2897        + 3 AD: 6 digits except evp) and offline_exf_seaice.seaice (12 digits).
2898    o pkg/salt_plume:
2899      - isolate saltPlumeFlux array exch into a specific S/R called from
2900        do_oceanic_phys.F
2901      - add interface to pkg/salt_plume (filling of saltPlumeFlux) in pkg/thsice.
2902    o verification:
2903      - move untested set-up to MITgcm_contrib/verification_other.
2904    o pkg/seaice:
2905      - retire old way of SEAICE_AGE. Now replaced with ALLOW_SITRACER.
2906    o pkg/seaice:
2907      - seaice_solve4temp.F (keeping results unchanged):
2908        * add 2 future run-time params to select which saturation vapor pressure
2909          formula is used and how post-iteration fluxes are set.
2910          Temporary set these 2 params according to option SOLVE4TEMP_LEGACY;
2911        * New piece of code (not used) to update surf. atmos. heat flux F_ia using
2912          the linearized expression to stay consistent with tsurf finding.
2913      - seaice_freedrift.F avoid floating exception in sqrt(y) since y=sqrt(x*x)-x
2914        can be < 0.
2915    o pkg/seaice/seaice_solve4temp.F (SOLVE4TEMP_LEGACY undef):
2916      - remove from F_ia (and from it's derivative dFiDTs1) the contribution of
2917        conductive heat flux F_c , and add it explicitly when updating tsurf as
2918        solution of: Fc = Fia + d/dT(Fia - Fc) *delta.tsurf
2919        so that now F_ia has a consistent meaning through the entire routine.
2920        This causes differences at truncation level: update output of fwd exp.
2921        global_ocean.cs32x15.seaice.
2922    o pkg/seaice:
2923      - lots of editing/cleaning in seaice_solve4temp.F + better documentation
2924        of arrays, sign/direction of fluxes; no effect on results.
2925      - replace hard coded 273.16 (=previous value of celsius2K) by celsius2K
2926        in seaice_budget_ocean.F & seaice_solve4temp.F (SOLVE4TEMP_LEGACY part);
2927        note: this should have been done before changing celsius2K default.
2928      - to keep results unchanged, add back old value of celsius2K in verification
2929        exp. input*/data : lab_sea (AD), offline_exf_seaice (fwd+AD) & seaice_obcs
2930      - replace hard coded seawater freezing temp in seaice_solve4temp.F (part
2931        SOLVE4TEMP_LEGACY) of 271.20 (=previous value of celsius2K + default
2932        value of SEAICE_freeze) by celsius2K+SEAICE_freeze so that seawater
2933        freezing temp is consistent with value in seaice_growth.F ; this causes
2934        differences at machine truncation level: update lab_sea AD output (3/4).
2935    o pkg/seaice:
2936      - mask (in exf_init_fixed.F) atemp,aqh,evap,precip,runoff,lwflx,areamask
2937        and climsst/sss even when using seaice (to prevent calculation that might
2938        use SST on land); does not affect any verification exp.
2939      - apply mask to taux,tauy (in seaice_get_dynforcing.F); update output
2940        of lab_sea.fd & lab_sea.hb87 and global_ocean.cs32x15.seaice_dynmix.
2941    o pkg/seaice/seaice_growth.F: add mask to avoid non-zero ice thickness
2942      over land (non-legacy code)
2943    o vectorize salt_plume package:
2944      - add extra code to salt_plume_frac and salt_plume_tendency_apply_s
2945      - this code computes plumebk everywhere (also over land), thus requires
2946        code to avoid divisions by zero and catch the case of kLev=Nr.
2947      - efficiency of salt_plume_frac is still sub-optimal
2948    o tools (genmake2):
2949      - fix makefile NAME specification (option: -makefile NAME) by adding
2950        "-f $MAKEFILE" in few places where it was missing including makedepend
2951        command (contribution from Paul).
2952    
2953    checkpoint63i (2012/01/24)
2954    o model/src:
2955      - add factorized versions of some EOS code to find_rho.F,
2956        define USE_FACTORIZED_EOS to turn it on (default for TARGET_NEC_SX)
2957    o model/src:
2958      - add celsius2K to namelist PARM01; remove unused recip_rhoNil from PARAMS.h;
2959      - change default celsius2K from 273.16 to 273.15
2960      - to keep results unchanged, add back old value of celsius2K in verification
2961        exp. input*/data : aim.5l_cs, 1D_ocean_ice_column, lab_sea (fwd),
2962         global_ocean.cs32x15(seaice) & cpl_aim+ocn(input_atm).
2963    o model/src: add a little initialisation trick to find_rho.F and find_alpha.F
2964      to make TAF generate vectorizable code
2965    o pkg/seaice/seaice_evp.F: add code (copied from CICE) that avoids underflows.
2966       Turn on by defining SEAICE_EVP_ELIMINATE_UNDERFLOWS. Most compilers
2967       have flags that do this more efficiently.
2968    o pkg/diagnostics/diagstats_calc.F
2969      - for TARGET_NEC_SX fix the treatment of the scaling factor tmpFac=scaleFact
2970    o pkg/obcs (with exch2):
2971      - derive OB indices in overlap region from OB-InsideMask (in obcs_init_fixed.F)
2972        and remove code (in obcs_readparms.F) which was based on EXCH of indices
2973        (through buffer) and did not account for exch2 (e.g., CS-grid) topology.
2974    o pkg/exf and seaice exp:
2975      - change offline_exf_seaice.seaicetd test exp. to use default DIFF1 value (=0)
2976        so that switching off area & heff advection flags does not affect results.
2977      - change default EXF_LWDOWN_WITH_EMISSIVITY to #define in EXF_OPTIONS.h
2978      - keep exp. seaice_obcs & 1D_ocean_ice_column(ad) unchanged (using #undef
2979        EXF_LWDOWN_WITH_EMISSIVITY) and, using pkg/exf default emissivities, update
2980        results of verification experiments: 1D_ocean_ice_column(fwd),
2981        global_ocean.cs32x15.seaice(fwd+ad) & seaice_dynmix(ad), lab_sea (all 8)
2982        and offline_exf_seaice (all 4).
2983    o pkg/seaice:
2984      - remove array YNEG, RIVER, TMIX (replaced by local var) from common block;
2985        remove also areaNm1 & hEffNm1 when SEAICE_GROWTH_LEGACY is undef.
2986      - fix bug: areaNm1 & hEffNm1 are needed in seaice_growth (SEAICE_GROWTH_LEGACY)
2987        but were not filled when resp. SEAICEadvArea=F & SEAICEadvHeff=F and
2988        not multi-dim advection;
2989      - fix seaice_growth.F to compile with both SEAICE_GROWTH_LEGACY and
2990        SHORTWAVE_HEATING #undef.
2991    o optim: make Makefile more robust (?)
2992    o pkg/obcs:
2993      * fix treatment of obcs_read_pickup for TAF
2994    o pkg/shelfice:
2995      * add missing initialisation of num_shifwflx
2996      * new adjoint verification exp. for isomip
2997      * change Prandtl and Schmidt numbers from generic formulations
2998        (in terms of model diffus. and visc.) to separate runtime
2999        parameters, with Holland and Jenkins (1999) default values.
3000    o pkg/exf (interpolation):
3001      - extended input field (2 rows) near the N & S poles:
3002        * fill in with the symetric value (when even Nb of data in longitude)
3003        * add average value at the poles only for scalar quantities ; for vector
3004          component interpolation, skip the averaging and keep duplicated values,
3005          unless the 2 components have same location (uvInterp=T) in which case
3006          interpolate the 2 components together using S/R EXF_INTERP_UV.
3007      - new S/R EXF_INTERP_UV to interpolate the 2 components of a vector field
3008        together: this allows to account properly for local orientation when
3009        averaging at N & S pole.
3010      - add CPP option EXF_USE_OLD_INTERP_POLE to recover old results regarding
3011        exf-interpolation near N & S poles. Undef by default.
3012      - add debug check/print on 1rst iter if debugLevel >=2.
3013    o pkg/exf:
3014      - change masking flags definition (no longer "parameter"), put them in
3015        common block and set them in S/R EXF_INIT_FIXED.
3016      - change recognized masking flag from s,u,v to c,w,s since the mask
3017        to use (maskC,W,S) depends on position on model grid and has little to
3018        do with scalar/vector difference; fix masking if using P-coordinates.
3019      - fix masking of wind-stress (was wrong if interpolated or read on A-grid)
3020        and update results of exp. global_with_exf (x2).
3021      - fix setting of zenith-angle table when SHORTWAVE_HEATING is undef.
3022    o pkg/obcs
3023      - S/R obcs_calc_stevens: fix a small bug (gammat -> gammas where appropriate)
3024    o pkg/exf (interpolation):
3025      - assume periodicity in X only if input field cover full longitude range.
3026      - improve search for lat. index (supposed to be faster, in ~log2(ny) steps,
3027        and should vectorise).
3028      - fix input lat of the 2 added row (in case we provide N.pole data).
3029    
3030    checkpoint63h (2011/12/30)
3031    o pkg/seaice:
3032      - change declaration of UVM from _RL to _RS in order to get B-grid
3033        uIce,vIce monitor when _RS = real*4
3034    o pkg/offline:
3035      - new S/R OFFLINE_RESET_PARMS for resetting main-model params (switch off flags);
3036      - compute vertical velocity if not read from file (switch on exactConserv
3037        & staggerTimeStep);
3038      - fix output of ptracer monitor iter & time for default PTRACERS_monitorFreq.
3039    o verification:
3040      - update grid-files (in tutorial_held_suarez_cs/input and fizhi-cs-32x32x40/input)
3041        with grid-angle generated using "utils/matlab/cs_grid/cubeCalcAngle.m":
3042        fix Pb in yG definition @ 2 missing corners (previously yG was averaged);
3043      - update output of exp. global_ocean.cs32x15.viscA4 after changing
3044        grid-file angles (used here for coriolis-3d);
3045      - remove (or gzip) few files not needed to run fizhi-cs experiments.
3046    o pkg/exf (vector interpolation):
3047      - rotate vector component toward local grid-axis orientation using grid-angles
3048        (stored in GRID.h) instead of locally computed rotation angle; keep old code
3049        available with exf option EXF_USE_OLD_VEC_ROTATION (undef by default).
3050    o pkg/seaice:
3051      - allow to compile with exf options ALLOW_ATM_TEMP or ALLOW_DOWNWARD_RADIATION
3052        undefined. Fix and remove the stop when ALLOW_RUNOFF is undefined.
3053    o pkg/PKG_OPTIONS.h files:
3054      - move #include "CPP_OPTIONS.h" just after #include "PACKAGES_CONFIG.h",
3055        outside of the #ifdef ALLOW_THISPKG / #endif block.
3056      - update verification/*/code/PKG_OPTIONS.h files.
3057    o add a verification experiment (offline_exf_seaice/input.seaice) that test
3058      the B-grid LSOR solver
3059    o pkg/seaice: sort out emissivity and long wave radiation step 2:
3060      - add emissivity for snow and ice as new run-time parameters
3061        (unfortunately) that default to the corresponding exf values; this
3062        changes results in most verification experiments so that for backward
3063        compatibility these parameter have to be set explicitly to inconsistent
3064        values (ugly);
3065      - the exf-flag EXF_LWDOWN_WITH_EMISSIVITY then gets rid off the hard-wired
3066        emissivities of 0.97 associated with lwdownloc in S/R seaice_solve4temp
3067        until we agree how to handle this bug properly
3068    o pkg/exf (interpolation):
3069      - add a set of run-time param ({inputfield}_interpMethod), one for
3070        each interpolated input field, to select the interpolation method
3071        with a value of zero switching off the interpolation;
3072      - print interpolation parameters to standard output;
3073      - refine exf_check.F accordingly ; stop if USE_NO_INTERP_RUNOFF is defined
3074        (to use instead runoff_interpMethod=0 in data.exf).
3075      - simplify default setting of interpolation parameters (for all fields,
3076        set position to match model grid cell-center position, leading to trivial
3077        interpolation in case of regular Lat-Lon grid) and fix for the case of
3078        non-uniform delY.
3079    o pkg/exf/exf_radiation.F: add the factor ocean_emissivity to lwdown, for
3080       within #ifdef EXF_LWDOWN_WITH_EMISSIVITY/#endif. Unless ocean_emissivity=1.
3081       this factor is absolutely required, because the lw exitance (= out-going
3082       long wave radiation) is emissivity*stefanBoltzmann*T^4 + rho*lwdown,
3083       where the reflectivity rho = 1-emissivity for conservation reasons. Once
3084       this is established, we can remove the CPP-Flag (if we want to).
3085    o pkg/seaice:
3086      - qualify a stop statement in S/R seaice_check: EXF_READ_EVAP and
3087        ALLOW_BULKFORMULAE are only required if SEAICE_EXTERNAL_FLUXES is defined
3088      - sort out emissivity and long wave radiation, step 1: make SEAICE_emissivity
3089        what the name implies (and not emissivity*BoltzmannConstant), this means
3090        the old default value of 5.5e-8 now means
3091        5.5e-8/5.670e-8 = 0.97001763668430343479 as ocean_emissivity in
3092        S/R exf_readparms
3093      - FV-discretization of the B-grid LSOR solver, turn on with
3094        SEAICE_LSRBNEW. This new solver also involves a slight re-organization
3095        of the calling routine dynsolver, so that B and C-grid code look a
3096        little more alike.
3097      - fix index bugs in ostres.F (B-grid code)
3098    o pkg/seaice/seaice_ocean_budget.F: change (unused) code to make it look better
3099    o pkg/seaice/seaice_readparms.F: make ocean_emissivity*stefanBoltzmann the
3100      default for SEAICE_emissivity, if useEXF; requires setting a wrong
3101      parameter value in global_ocean.cs32x15/input.seaice/data.seaice for
3102      backward compatiblity
3103    o model/src: use sigmaR in calc_ivdc
3104    
3105    checkpoint63g (2011/12/16)
3106    o pkg/seaice/seaice_growth.F:
3107      fix heat conservation of the coupled ocean-seaice system.
3108      when SEAICE_HEAT_CONSERV_FIX is defined, the mismatch of
3109      solid vs liquid water treatment is resolved via QNET.
3110    o pkg/seaice/seaice_growth.F:
3111      add missing term for sublimation in saltFlux, which was breaking conservation.
3112    o pkg/seaice/seaice_model.F:
3113      Remove this patholigical case treatment in evolution branch,
3114      where it is un-necessary and breaks conservation.
3115      Update global_ocean.cs32x15/results accordingly for
3116      output.seaice.txt output_adm.seaice.txt and output_adm.seaice_dynmix.txt
3117    o model/src:
3118      useRealFreshWaterFlux: remove masking of EmPmP (using maskInC) in
3119      external_forcing_surf.F and apply mask directly in S/R SOLVE_FOR_PRESSURE.
3120    o pkg/obcs:
3121      modify Stevens boundary conditions so that S/R obcs_calc_stevens computes
3122      tendency for temperature and salinity that is then applied to update
3123      theta and salt in S/R obcs_apply_ts; this requires proper masking of all
3124      horizontal advection and diffusion contributions on the boundary (in
3125      S/Rs gad_advection, gad_calc_rhs, gmredi_rtransport, gmredi_calc_diff), and
3126      removing the mask in S/R timestep_tracer. The advantage of this approach is
3127      that the updated tracer values include contributions from the surface
3128      forcing and vertical diffusion.
3129      This modification changes exp4.stevens because of vertical diffusion.
3130    o model/src:
3131      change non-curvilinear grid setting to also work with exch2 + blank tiles:
3132      - move delX,delY to new header file (SET_GRID.h) and adjust length to 1rst
3133        face dimensions.
3134      - new S/R INI_LOCAL_GRID to define model tile-local grid (using same units
3135        as delX,delY) and called from S/R INI_CARTESIAN_GRID, INI_CYLINDER_GRID
3136        and INI_SPHERICAL_POLAR_GRID.
3137      change test-experiment global_ocean.90x40x15:
3138      - split the domain in many more tiles (9x4 tiles of 10x10 each);
3139      - switch to exch2 and remove 1 blank-tile (but only for MPI test).
3140      - update results of both test (std & dwnslp).
3141    o pkg/diagnostics/diagstat_calc.F: fix problem with non-initialised halos in
3142       tmp-fields for TARGET_NEC_SX at the cost of extra loops and less vectorisation
3143    o model/src:
3144      - take sigma-coords related code out of update_etah.F into new S/R UPDATE_ETAWS
3145        and fix initialisation when using sigma-coords.
3146    o model/src:
3147     - improve Gael's changes from Jan 14, 2011 "addition of an 'update' of hfacc etc.
3148       to their current value at the beginning of forward_step.F": add a new run-time
3149       switch "doResetHFactors" (default=false) and use it to do (or not) the resetting.
3150     - set doResetHFactors=T in the following test exp:
3151        global_ocean.90x40x15/input (rStar) & input.dwnslp (linFS),
3152        global_ocean.cs32x15/input.seaice (rStar), hs94.cs-32x32x5/input.impIGW (linFS)
3153        and tutorial_global_oce_in_p (nonLinFS in p)
3154    o pkg/ecco
3155      - added IES cost term
3156    o verification/advect_xz
3157      - scale down the depth by 1/100 (from 200 km to just 2.km)
3158      - add secondary test using divergent flow, r-star and implicit vertical advection.
3159      - add note (check_conserve_TS.txt) and matlab script to check global
3160        conservation of T & S with NonLin-FreeSurf and Adams-Bashforth.
3161    o pkg/rbcs:
3162      - add missing relaxUFile & relaxVFile in namelist (in rbcs_readparms.F).
3163    o pkg/obcs (Stevens BCs):
3164      - fix various problems in the phase speed computations of the Stevens
3165        boundary conditions:
3166        - sign error for western and southern boundaries,
3167        - time tendencies were underestimated by factor of dTracerLev and some just
3168          zero (for multidim advection schemes) -> now estimate time tendencies
3169          from difference between previous (n) time level and the one before (n-1);
3170          this requires storing a field per tracer per boundary, also in the pickup
3171          files.
3172        - replace deltaTmom in cflMer/Zon computation with dTracerLev
3173        - set default phase velocity to cflMer/Zon
3174      - update verification experiment exp4.stevens
3175    o pkg/generic_advdiff (implicit_r):
3176      - fix implicit vertical advection conservation with AB and/or NonLin-FreeSurf
3177        (remove Tr*d/dz(w) in gad_implicit_r.F and add it in gad_calc_rhs.F);
3178      - fix implicit vertical diffusion or advection with NonLin FreeSurf
3179        (was using current recip_hFacC instead of future recip_hFacC): set future
3180        recip_hFac in thermodynamics.F and pass & use it in all vertical implicit
3181        solver S/R ;
3182      - fill diagnostics of vertical advective fluxes (computed from tendency)
3183        when using implicit vert. advection;
3184      - update output of exp that uses NonLin-FreeSurf & implicit vertical diffusion:
3185         global_ocean.90x40x15 (fwd+AD), global_ocean.cs32x15 (4 fwd +4 AD),
3186         tutorial_global_oce_in_p (fwd), tutorial_tracer_adjsens (AD)
3187         and cpl_aim+ocn (used in ocean); to be fixed: bottom_ctrl_5x5.
3188    o pkg/diagnostics:
3189      - add diags for T & S tendency which goes through Adams-Bashforth.
3190    
3191    checkpoint63f (2011/11/30)
3192    o pkg/obcs/obcs_calc_stevens.F:
3193      - join some loops to reduce number of if-statements
3194      - fix a bug in code for northern and southern boundaries.
3195    o pkg/seaice/seaice_init_varia.F
3196      - undo resetting UVM=0 that has slipped in unnoticed in r1.49 and
3197        caused zero ice-velocities for the B-grid code
3198    o pkg/seaice/seaice_init_fixed.F
3199      - fix a bug in the initialisation of the second metric terms
3200        k2AtC and k2AtZ: k2AtC was set to the value of k2AtZ and k2AtZ was 0.
3201      - this affects all seaice configurations with useCurviLinearGrid = .true.
3202        and SEAICEuseDynamics = .true. (default) and SEAICEuseMetricTerms
3203        = .true. (default)
3204      - the only verification experiment affected is global_ocean.cs32x15:
3205        icedyn, seaice, and seaice_dynmix (AD)
3206    o pkg/thsice/thsice_diagnostics_state.F
3207      - only for TARGET_NEC_SX: initialise all of tmpFld, so that overlap does
3208        not contain garbage that can lead to surprises in diagstats_calc.F
3209    o model/src:
3210      - move bi,bj loops inside INTEGR_CONTINUITY ;
3211      - call INTEGR_CONTINUITY directly from forward_step.F
3212        (previously called from momentum_correction_step.F)
3213      - call UPDATE_ETAH from integr_continuity.F and update initialise_varia.F,
3214        forward_step.F and pkg/ecco/the_main_loop.F
3215    o model/src/do_oceanic_phys.F:
3216      - reset addMass to zero only if useICEFRONT ;
3217      - separated k-loop for rhoInSitu calculation ;
3218      - add 2 diagnostics for wVel*delta^k(Rho) at constant pressure (= WdRHO_P)
3219        and at constant T,S (= WdRHOdP);
3220      NOTE: change diagnostics WRHOMASS : this is now simply the Vertical transport
3221        of In-Situ Density (Anomaly) (=wVel*rho^bar-k) (previously was Vertical
3222        transport of locally-referenced potential density);
3223        to recover old diag: (WRHOMASS)_old = (WRHOMASS)_new -1/2 * (WdRHOdP)
3224    o gluemnc:
3225      - replace ncrcat with ncks when adding variables to *.glob.nc
3226      - change the way variables without record dimensions are handled so that
3227        files that have variables with and without record variables can be glued:
3228        add a record dimension with a new unique name to be able to differentiate
3229        between variable with and without a-prior record dimensions. Remove
3230        this record dimension before adding the variable to the *.glob.nc file.
3231        This procedure automatically works also for grid.*.nc files that do not
3232        have any record dimension.
3233    o verification/cpl_aim+ocn:
3234      - generate new reference output on baudelaire (gfortran, mpich2) (previously
3235        from old aces-grid cluster, ao + ifort) and update 'run_cpl_test' script.
3236    o pkg/obcs/obcs_calc_stevens.F:
3237      - add code for northern and southern boundaries.
3238      - reorder some loops to save some operations and so that drFBar can be scalar
3239    o model/src:
3240      - re-arrange extrapolation calculation in Adams-Bashforth S/R (affects machine
3241        truncation) and add diagnostics for Adams-Bashforth tendency increment.
3242      - update test-exp. AD output:
3243        1D_ocean_ice_column, bottom_ctrl_5x5, lab_sea.noseaicedyn, obcs_ctrl;
3244      and FWD output: exp4 (x3), fizhi-cs-32x32x40, fizhi-cs-aqualev20,
3245        front_relax (x3), global_ocean.90x40x15 (x2), global_ocean.cs32x15 (x5),
3246        global_ocean_ebm, ideal_2D_oce, internal_wave, isomip (x3), lab_sea (x4),
3247        matrix_example, MLAdjust (x5), natl_box (x2), tutorial_advection_in_gyre,
3248        tutorial_global_oce_in_p, tutorial_global_oce_latlon and
3249        tutorial_plume_on_slope.
3250    o pkg/diagnostics/diagstats_calc.F: add special code for TARGET_NEC_SX
3251      that vectorises. This code uses 3 extra 2D fields, F90 array assignments
3252      and F90 intrinsic routines SUM, MINVAL, MAXVAL, but since TARGET_NEC_SX
3253      does not even come with an F77 compiler anymore, this should not be
3254      a limitation
3255    
3256    checkpoint63e (2011/11/06)
3257    o pkg/seaice adjoint of LSR:
3258      - substantially rework STORE dirs.
3259      - add new flag SEAICE_LSR_ADJOINT_ITER and parameter SOLV_MAX_FIXED
3260        this flag will do SOLV_MAX_ITERS but only store SOLV_MAX_FIXED fields
3261        and only perform SOLV_MAX_FIXED adjoint iters.
3262        If flag SEAICE_LSR_ADJOINT_ITER is undef-ined, the store in the iteration
3263        always goes to same record, meaning that the last forward field will be
3264        the one used in the adjoint - an approximation.
3265      - now produces non-zero LSR-related gradients, and acceptable gradients for
3266        An's zonal (x-z) test case (to be checked in)
3267      - lab_sea: produces acceptable gradients for lab_sea with forward/backward LSR
3268        (but these are screwed up by the thermodynamics in the first place);
3269        reduce from 4 to 3 timesteps to avoid t.d. issue as temporary solution;
3270        output_adm.txt also reflects changes to seaice_lsr
3271      - global_ocean.cs32x15:
3272        * the "default" input_ad.seaice has been re-defined to always exclude dynamics
3273          (output_adm.seaice.txt was updated)
3274        * new input_ad.seaice_dynmix tests a forward LSR / backward free-drift
3275          (output_adm.seaice_dynmix.txt)
3276    o test-exp. exp4+stevens:
3277      - switch off pTracers and nonHydrostatic (restart problems with NH); update output
3278    o pkg/seaice (lsr solver):
3279      - put coriolis term into FORCEX,Y (as in seaice_evp.F; previously in rhsU,V only);
3280        update output (change truncation) of FWD test exp lab_sea & global_ocean.cs32x15
3281      - fix SEAICEuseFREEDRIFT for new OBCS version (ndef OBCS_UVICE_OLD)
3282      - new parameter "LSR_mixIniGuess" allows (if=2,4) to mix free-drift solution
3283        into initial guess for linearised solver; use weight ~ (1/err)^2,4.
3284      - compute (with new S/R) and print initial (+ free-driff sol. if available)
3285        and final residual of linearised system.
3286    o pkg/pp81: add diagnostics for vertical eddy viscosity and diffusivity
3287      (requires new subroutines pp81_init_fixed.F/pp81_diagnostics_init.F)
3288    o pkg/obcs: Stevens BCs (still only for east and west)
3289      - fix Stevens BCs by using intermediate velocities of previous
3290        time step as "baroclinic" contribution rather velocity of one grid cell
3291        inside the boundaries; more consistent but makes the entire treatment
3292        more complicated, requires new pickup files and two new S/Rs:
3293        obcs_copy_uv_n and obcs_save_uv_n
3294        keep old version with flag OBCS_STEVENS_USE_INTERIOR_VELOCITY
3295        (undefined by default)
3296      - silently move computation of some grid factors into separate loops to
3297        save some recomputations
3298      - add a hack for non-linear free surface
3299      - add a verification experiment to exp4 that tests this code
3300    o make gluemnc/xplodemnc work with (moron) non-GNU shell tools
3301    
3302    checkpoint63d (2011/10/25)
3303    o pkg/obcs + seaice-dynamics:
3304      - new implementation calls OBCS_APPLY_UVICE (in seaice_dynsolver.F) before
3305        solving for uIce,vIce and prevent SEAICE_LSR or SEAICE_EVP to modify OB
3306        values (consistent with an implicit method).
3307      - add option OBCS_UVICE_OLD (in OBCS_OPTIONS.h, defined by default) to
3308        return to older implementation (same results as before); note that none of
3309        the "experimental" OBCS_SEAICE options are implemented in the new version.
3310      - switch test exp. seaice_obcs to use new version (update output).
3311    o pkg/seaice:
3312      - add few stop (B-grid & CS-exch, B-grid & obcs, AUTODIFF & SEAICE_maskRHS)
3313      - add parenthesis in Water-Ice drag calculations (evp & lsr);
3314      - in seaice_lsr.F, simplify and fix AA3 setting in case sNx or sNy=1;
3315        and fix case SEAICE_waterDrag=0 (but unstable if no or little seaice)
3316      - update output of test exp lab_sea that uses evp or lsr (fwd+ad)
3317        and global_ocean.cs32x15 (icedyn & seaice fwd+ad).
3318    o pkg/layers:
3319      - Include potential density as new coordinate (Thanks to David Munday)
3320    o pkg/dic:
3321      - Remove subroutine CALC_PCO2_APPROX_CO3 from carbon_chem.F and add
3322        carbonate computation/output to CALC_PCO2_APPROX
3323    o pkg/generic_advdiff
3324      - make TAF generate code that vectorizes:
3325        gad_dst3fl_adv_*.F, gad_u3c4_impl_r.F
3326    o model/src:
3327      - improve vectorization also for adjoint code of
3328        solve_tridiagonal and solve_pentadiagonal. As this requires up to
3329        5 new 3D-fields, this code is only turned on for the combination of
3330        ALLOW_AUTODIFF_TAMC and TARGET_NEC_SX. Also remove error message
3331        for singular matrix check (only for TARGET_NEC_SX).
3332      - remove hard-wiring of CPP-flag ALLOW_SOLVERS_KLOOPINSIDE to
3333        ALLOW_AUTODIFF. This flag now needs to be set outside of
3334        solve_tri/pentadiagonal.F
3335    o pkg/exf:
3336      - fix previous modif in exf_readparms.F (revision 1.66: treatment of
3337        optional namelist EXF_NML_OBCS).
3338      - add many debug-print (to trace down where pkg/cal error msg comes from)
3339    o pkg/mom_vecinv/mom_vi_hdissip.F
3340      - rearrange loops so that vectorization is improved and in particular
3341        the adjoint routine vectorizes. The code is a little longer now, but I
3342        think easier to read.
3343        Note: CPP-flag MOM_VI_ORIGINAL_VISCA4 is not tested.
3344    o pkg/seaice:
3345      - allow to specify initial seaice velocity from files (uIceFile,vIceFile)
3346    o pkg/exch2:
3347      - alternative code (without tile x tile matrix) for cumulated (global) sum;
3348        used as default; keep using matrix version in adjustment.cs-32x32x1.
3349    o tools/build_options:
3350      - after merging some MPI and/or multi-threads specific optfiles so that
3351        the modified default optfile support both built (using genmake2 -mpi
3352        for the MPI built, using genmake2 -omp for OpenMP built),
3353        move now obsolete optfiles to tools/build_options/unsupported/
3354       (add copy of email sent to support list in doc/optfiles_changes.txt)
3355    
3356    checkpoint63c (2011/09/28)
3357    o pkg/ebm:
3358      - fix ebm_zonalmean.F for several procs in Ydir (nPy > 1); update output of
3359        test exp. global_ocean_ebm (affects machine truncation, 12 digits for cg2d)
3360    o pkg/seaice (SItracer pickup)
3361    * Simple code for pickup of SItracer fields (#define ALLOW_SITRACER)
3362      To be done:
3363      - thorough testing of missing fields in S/R seaice_read_pickup
3364      - thorough matching between generic tracers and specific fields used
3365        (e.g. volume-weighted age, area-weighted age, salinity, ...)
3366    o pkg/grdchk:
3367      - all procs calculate and print finite-difference gradient (for testreport)
3368      - change description output used by testreport;
3369      - AD testing: also compare and report Finite-difference gradient;
3370        => update all output_adm*.txt
3371    o test exp. global_ocean_ebm:
3372      - switch back useRealFreshWaterFlux (no problem anymore with run-off);
3373        and turn on exactConserve; update (fwd) output.
3374    o pkg/seaice (LSR):
3375      - print to STDOUT number of solver iterations at SEAICE_monFreq interval.
3376      - modify solver to deal cleanly with u/v switch at face edges (CS-grid):
3377        * identical results with non-CS topology (but save up to half of EXCH calls)
3378        * no much changes in cs-32 verification tests since no ice at face edges
3379         (differences due to convergence criteria, since nb of iterations changed)
3380        * expect some differences on lat-lon-cap grid.
3381        update FWD results of global_ocean.cs32x15 test exp. (icedyn & seaice)
3382    o pkg/exch2:
3383      - add new CPP option to disable Cumul-Sum matrix (to save storage when using
3384        many tiles); until alternative coding is added, just add a stop.
3385    o pkg/kpp:
3386      - move ptracer/salt correction to KPP diffusivity from calc_3d_diffusivity.F
3387        to S/R KPP_CALC_DIFF_PTR (+ add tracer-index to argument list).
3388    o optfiles:
3389      - merged few MPI specific (*+mpi*) and multi-threads specific (*+mth) optfiles
3390        into corresponding standard one, which now support different build:
3391        (when using "genmake2 -mpi" for MPI built, "genmake2 -omp" for OpenMP built)
3392      - add "darwin_amd64_gfortran" optfile (initially from Constantinos, tested by Gael)
3393    o pkg/obcs (seaice):
3394      - add missing EXCH for uIce,vIce after applying OBCS;
3395      - remove S/R EXF_SWAPFFIELDS_X/Y , disable S/R EXF_SET_OBCS_X/Y by adding
3396        argument = number of levels to S/R EXF_SWAPFFIELDS_XZ/YZ and S/R
3397        EXF_SET_OBCS_XZ/YZ ; update obcs_exf_load.F;
3398      - fix EXF_SET_OBCS_XZ/YZ for multi-threaded (assuming loaded arrays are shared)
3399      - verification exp. seaice_obcs: split domain in 2 tiles ; add SIZE.h_mpi
3400        and eedata.mth for MPI and mutlti-threaded testing.
3401    o pkg/flt:
3402      - make FLT EXCH working with multi-threads (and MPI + multi-threads);
3403      - use buffer for floats IO (trajectories & profiles); size set in FLT_SIZE.h;
3404      - fix pickup and trajectories + profiles output with multi-threads;
3405      - add parameter to select group of fields to write along trajectory and
3406        profile (default unchanged);
3407      - only call PORT_RAND* function when flt_noise <> 0;
3408      - add multi-threaded test for verification exp. flt_example.
3409    o eesupp/src:
3410      - fix S/R ALL_PROC_DIE for MPI+multi-threads.
3411      - USE_OMP_THREADING: check that number of threads (from eedata) matches
3412        actual number (from env.var. setting).
3413    o pkg/ebm:
3414      - fix multi-threading in ebm_area_t.F ; clean-up EBM.h header file.
3415      - add multi-threaded test for verification exp. global_ocean_ebm
3416    
3417    checkpoint63b (2011/08/29)
3418    o pkg/ebm:
3419      - fix sign of runoff;
3420      - update directly forcing fields (Qnet,EmPmR) to use standard
3421        external_forcing_surf.F (remove ebm_forcing_surf.F);
3422      - avoid loading forcing fields a 2nd time (1rst time from ini_forcing.F);
3423      - set either tauThetaClimRelax (in data) or tauThetaZonRelax (in data.ebm)
3424        and apply relaxation towards corresponding SST field (2-D map or ZonAver).
3425      - update global_ocean_ebm parameters file data and update output (fwd+ad).
3426    o verification/matrix_example:
3427      - split domain in 8 tiles (2x4); add SIZE.h_mpi and eedata.mth for
3428        MPI and mutlti-threaded testing.
3429    o pkg/matrix:
3430      - change name of S/R MATRIX_INIT to S/R MATRIX_INIT_VARIA ;
3431      - fix for multi-tiles (add bi,bj indices to exp/impMatrixCounter);
3432      - fix for multi-threaded (remove DATA statement);
3433      - use standard DIFFERENT_MULTIPLE function;
3434      - add MATRIX_OPTIONS.h
3435    o verification/matrix_example:
3436       To allow to split the domain in several tiles, change the domain size
3437        from 31x31 to 32x32 by adding 1 row (on Southern side) + 1 column (on
3438        Western side) of land points.
3439    o (*_)write_pickup:
3440      - fix few bugs in mypackage_read/write_pickup.F
3441      - in MDS_WR_METAFILES calls, replace "myTime" by a local copy into
3442        array of length 1 (was caught by compiler syntax-check).
3443    o pkg/diagnostics (velocity potential solver):
3444      - fix initialisation of main diagonal matrix (for overlap values)
3445    o tools/build_options:
3446      - towards single optfile for MPI and non-MPI built: merge few +mpi optfile
3447        into previously non MPI one (linux_am64 pgf77,open64,pathf90,ifort11)
3448      - linux_amd64_gfortran: merge +mpi_generic version into standard optfile:
3449        * move IEEE flags to DEVEL section; take IEEE flags from +mpi_generic ;
3450        * FAST case: for now, keep -O3 with ini_masks_etc.F in NOOPTFILES list;
3451        and use "-devel" testreport option for standard testing on baudelaire.
3452    o pkg/grdchk:
3453      - Assume that all gradient-check position are within the same tile
3454        corresponding to global indices (iGloTile,jGloTile) and that
3455        positions (i,j indices or nbeg) are local to this tile;
3456      - set tile local-indices and proc. number according to tile global-indices;
3457      - remove grdchkwhichproc from namelist (retired param);
3458      - send adjoint gradient to all procs so that all procs print it to STDOUT;
3459      - switch on MPI test for global_ocean.90x40x15 AD test experiment.
3460    o adding package bbl (Bottom Boundary Layer)
3461      description in MITgcm/pkg/bbl/bbl_description.tex
3462      example/test experiment in MITgcm_contrib/bbl
3463    o adjoint verifications
3464      - changed 5 experiments to multi-tiles
3465        * global_ocean.90x40x15
3466        * obcs_ctrl
3467        * offline_exf_seaice
3468        * tutorial_dic_adjoffline
3469        * tutorial_tracer_adjsens
3470        changed reference output for those that crossed tile boundaries
3471        (changed choices of gradient check positions)
3472      - with same tiling, switch on MPI test for the last 4 (add SIZE.h_mpi)
3473      - temporary bug fix in grdchk_loc.F for obcs
3474    o genmake2 & testreport
3475      - add target "obj" (just for OBJFILES files) to Makefile;
3476      - add option to specify FEXTRAFLAGS on command line.
3477    o pkg/mypackage:
3478      - remove bi,bj arguments from argument list of S/R MYPACKAGE_CALC_RHS
3479    
3480    checkpoint63a (2011/08/02)
3481    o pkg/diagnostics (velocity potential):
3482      - fix velocity-potential calculation when using OBCS: balance net inflow
3483        at each level (new S/R OBCS_DIAG_BALANCE).
3484      - fix some of the problems with OBCS in stream-function calculation.
3485    o pkg/exf/exf_readparms.F
3486      - make treatment of optional namelists (EXF_NML_04, EXF_NML_SGRUNOFF,
3487        EXF_NML_OBCS) more consistent, so that you need not have these lists
3488        in data.exf when they are not used.
3489    o optim/optim_readdata.F:
3490      - add some output about obcs variables that might help debugging
3491      - add a check about nvarlength
3492    o pkg/ctrl: once again, fix computation of endrec in s/r ctrl_init_rec
3493    o pkg/diagnostics (velocity potential):
3494      - fix mask for OBCS (still problems in stream-function with OBCS);
3495      - add specific parameter (default = main code CG2D params) for solver;
3496      - in case of poor convergence, use solution corresponding to lowest residual.
3497    o pkg/seaice/seaice_growth.F: small changes that permit vectorizable
3498      adjoint code. In general statements like tmpscal=fld(i,j) are problematic
3499      and should be avoided where possible.
3500    o model/src (rStar):
3501      - include r* effect on reference-state (PhiRef) in totPhiHyd
3502        (so that it's really the potential anomaly at the cell center);
3503        affect solution only if z* with full pressure in EOS.
3504      - test-exp global_ocean.90x40x15: reduce viscA4 (was not stable) and
3505        update output (because of z* in totPhiHyd and viscA4 changes);
3506      - keep the previous diagnostics as "PHIHYDcR" (closer to potential anomaly
3507        @ constant r) until interpolation at constant r is implemented.
3508    o pkg/diagnostics
3509      - fix RCENTER diagnostics in case cell center is not at interface middle
3510    o add code for TEOS-10 (www.teos-10.org, McDougall et al. 2011). Use
3511      this eos with eosType = 'TEOS10', in data (PARM01). This eos implies
3512      that THETA and SALT are "conservative temperature" and "absolute
3513      salinity"
3514    o pkg/ctrl
3515      - fix computation of endrec in s/r ctrl_init_rec
3516      - ctrl_pack/unpack_*: remove unused variables and some obsolete code
3517    o pkg/seaice/seaice_growth.F
3518      - fix recomputation with FENTY_AREA_EXPANSION_CONTRACTION code,
3519        remove then obsolete STORE directives
3520      - fix STORE directives for tice and tices, so that only the
3521        appropriate part of the fields are stored (and not the entire
3522        field); update global_ocean.cs32x15.seaice AD output.
3523      - cosmetic changes: adjust CPP flags and indentation for better
3524        legibilty
3525    o pkg/autodiff: add mnc-output of adBottomDragFld (code contributed by
3526      Chris Wilson)
3527    o pkg/gmredi:
3528       Add Sub-Meso Eddies parameterisation from Baylor (for now, disabled with TAF),
3529       and test it in verification exp. "front_relax.bvp" (update output.bvp.txt)
3530    
3531    checkpoint63  (2011/07/11)
3532    o pkg/exch2:
3533     - rename+move: nTiles in W2_EXCH2_PARAMS.h --> exch2_nTiles in W2_EXCH2_TOPOLOGY.h
3534     - exch2 version of Cumul-Sum routine: S/R W2_SET_MAP_CUMSUM set up the
3535       (2*nTiles)x(nTiles) Cumul-Sum matrix and Master Proc collects all tiles X,Y
3536       increments, calculates Cumul-Sum @ tile origin and sends results to each tile.
3537    o pkg/diagnostics:
3538     - deal with pairs of post-processed diags which are computed together; in
3539       particular, re-order list of diags within 1 file to save 2nd computation.
3540     - add S/R to compute velocity stream-function (called after velocity-potential
3541       calculation) from divergence free transport -> new diagnostics "PsiVEL".
3542     - add parameter to select grid-point location where PsiVEL == 0.
3543    o eesupp/src:
3544       new S/R to calculate cumulated sum on tiled array, corner grid-cell location
3545       (specific S/R needed with exch2 topology - for now, just print an error msg)
3546    o pkg/shelfice
3547     - Implement friction velocity-dependent transfer coefficients following
3548       Holland and Jenkins, JPO, 1999
3549       Original code by M. Losch with small modifs.
3550       Enable with CPP option SHI_ALLOW_GAMMAFRICT
3551       and runtime flag SHELFICEuseGammaFrict
3552    o verification lab_sea & global_ocean.cs32x15:
3553     - use tools/xmakedepend (instead of cyrus_makedepend, in genmake_local):
3554       does not miss some dependencies (but is slower) and also works with many files
3555       (default makedepend limitation for AD built).
3556     - use cyrus_makedepend in adjustment.128x64x1 (so that it still tested).
3557    o pkg/diagnostics:
3558     - add run-time parameter "useMissingValue" (def=False) to fill land-point
3559        (i.e., where mask=0) with MissingValue ; used only in MNC output file.
3560       This replaces CPP-option DIAGNOSTICS_MISSING_VALUE.
3561     - Extend the use of "missing_value" setting from data.diagnostics for the case
3562       of counter-diagnostics (where fraction-weight is zero). This applies both to
3563       MNC and MDS output files.
3564    o pkg/seaice/seaice_growth.F:
3565      - add 'a priori' cap of latent heat flux based on actual mass considerations
3566        when SEAICE_ADD_SUBLIMATION_TO_FWBUDGET is used in conjunction with the
3567        non-legacy seaice_solve4temp.
3568      - add diagnostic of the residual sublimation freshwater flux (the freshwater
3569        flux taken from the ocean if the total actual latent heat fluxes exceed
3570        the maximum)
3571      - remove the CPP switch around the *_FWbySublim unit change and move diagnostic
3572       fill for SIatmQnt, SIfwSubl, SIatmFW to the end of seaice_growth.F.
3573      - add diagnostic of the actual sublimation freshwater flux (that is 0. ifndef
3574       SEAICE_ADD_SUBLIMATION_TO_FWBUDGET) and of the latent heat flux (evap+sublim).
3575      - bug fix : frWtrAtm needs a_FWbySublim ifdef SEAICE_ADD_SUBLIMATION_TO_FWBUDGET.
3576      - bug fix : missing part to Martin's r_FWbySublim pathological case fix.
3577    o verification 1D_ocean_ice_column:
3578       made model domain truly 1x1x23 instead of 5x5x23 with only center cell (3,3,:) wet
3579       update results
3580    o pkg/diagnostics:
3581     - Implement setting of "Post-Processed" diagnostics (corresponding to gdiag(5)='P')
3582       which are not filled-up but computed from other diags ; In this case, the mate
3583       diag points to the primary (filled-up) diag to used for post processing.
3584     - Update Velocity-potential computation using post-processed diag framework.
3585     ==> Change the ordering of fields and time-periods in MDS output file
3586       when using periodic averaging: now writes one time record with the full set
3587       of fields for this time period, then the next time reccord (it used to be
3588       one field with the full set of time records then the next field).
3589         Note: this is now similar to NetCDF (MNC) output file. <==
3590    
3591    checkpoint62z (2011/06/21)
3592    o adjoint monitor:
3593     - Add adjoint monitor output for packages exf, seaice
3594       and update relevant testreport output
3595    o pkg/seaice:
3596     - re-order diags inits so that they appear in order in available_diagnostics.log
3597     - added diags: hsnow thermo. rates of change, area preceeding ridiging process,
3598       area/heff/hsnow preceeding thermodynamic growth/melt.
3599     - modified diag: SIdA; output actual effect, as the description states.
3600     - modified description: SIqneti, SIqneto, SIuheff, SIvheff, SIdAb*, HSNOW.
3601     - retired redundant diags: SIyneg, SIfice, SIsnwice, SIthdgrh.
3602       (SIyneg->SIdHbOCN; SIfice->SIdHbATC; SIsnwice->SIdHbFLO;
3603        and SIthdgrh->SIdHbOCN+SIdHbATC+SIdHbATO)
3604     - modified diags (2) : switch all SIdA*, SIdH*, SIdS* from delta to rates.
3605     - added diagnostics for seaice generic tracers (SItr*).
3606     - added SItrUnit and SItrNameLong run time param (for SItr* diags).
3607     - in diag names, replaced 'PrTh' abbrev. of 'preceeding thermo' with 'PT'.
3608     I. Fenty: 18-Jun-2011:
3609     Minor changes to seaice package:
3610     1) Retired old variables (A22, SEAICE_lhsublim, areaMax, areaMin, hiceMin) and
3611        added some new ones (SEAICE_area_reg, SEAICE_hice_reg, SEAICE_area_floor)
3612       - Differentiated "regularization variables" from "floor variables"
3613        * areaMin became SEAICE_area_reg (old A22) and SEAICE_area_floor
3614        * hiceMin became SEAICE_hice_reg (old hiceMin)
3615          (with _reg meaning regularization variable)
3616       - SEAICE_lhSublim becomes lhSublim, the sum of SEAICE_lhEvap and SEAICE_lhFusion
3617        so as to ensure energy conservation when going between phases
3618      - A22 was not used anywhere
3619     2) Changed regularization procedure for heffActual and hsnowActual to ensure
3620        well-boundedness and smooth adjoint in seaice_growth.F
3621     3) Fixed a bug where seaice_solve4temp would not recognize ice-free grid cells
3622        because the old regularization always set heffActual >= 0.05 cm
3623     4) Changed the model so that the default behavior is to put a small (10^-5) "floor"
3624        on AREA when HEFF > 0.
3625      - went from requiring ALLOW_PRECLUDE_INFINITESIMAL_AREA to be defined to
3626        requiring that DISABLE_AREA_FLOOR *not* be defined
3627     Affected verifications:
3628      - 1D_ocean_ice_column (output.txt output_adm.txt)
3629      - global_ocean.cs32x15 (output.seaice.txt output_adm.seaice.txt)
3630    o pkg/diagnostics:
3631      - move MNC code from diagnostics_out.F into new diagnostics_mnc_out.F (2 S/R).
3632      - rename S/R GETDIAG to DIAGNOSTICS_GET_DIAG and change type of 1rst argument
3633        (was _RL, now integer) with option = 0 to retrieve all levels.
3634      - add pieces of code to compute velocity potential at each level (new diagnostics
3635        PhiVEL, works only when UVELMASS & VVELMASS are also turned on);
3636        for now, using same params as CG2D (target-resisual, max Nb of iter ...).
3637      - fix few issues with counter diagnostics in diagnostics_setdiag.F &
3638        diagstats_setdiag.F (if diagnostic counter is itself a counter diag)
3639        and in diagnostics_fract_fill.F (do not need a valid pointer for the
3640        diagnostics counter-mate); check that definition of counter-diagnostic
3641        includes a valid counter-mate (in diagnostics_set_levels.F).
3642    o model/src (rStar):
3643      - add rStar scaling factor in diags_phi_hyd.F (similar to calc_grad_phi_hyd.F);
3644        affect solution only if z* with full pressure in EOS;
3645        update output of test-exp global_ocean.90x40x15.
3646    o pkg/seaice:
3647      - introduce siEps=1e-5 parameter
3648      - use areaMax in AREA update (part 4), consistent with ridging step (part 2.5).
3649      - re-organize SEAICE_ADD_SUBLIMATION_TO_FWBUDGET code.
3650      - introduce ALLOW_SITRACER and seaice_tracer_phys.F to handle generic seaice tracer.
3651        For now it covers, and was tested for, ice salinity and age (attached to HEFF),
3652        as well as ice cover age and ridging index (attached to AREA).
3653        For now the run time parameters (in data.seaice/SEAICE_PARM03) are
3654        SItrName (e.g. 'age') and SItrMate ('HEFF', which is the default, or 'AREA').
3655        Up to SItrMaxNum=3 tracers can be used simultaneously.
3656    o pkg/salt_plume:
3657      -introduce SPsalFRAC run time parameter that sets the fraction of the
3658       salt by-product of ice growth (SPsalFRAC*(1-SIsalFRAC)*salt typically)
3659       that gets vertically redistributed (fluxed down) by pkg/salt_plume.
3660    o model debug options:
3661      - Switch reading of debugMode from S/R INI_PARMS (parameter file "data", stored
3662        in PARAMS.h) to S/R EESET_PARMS (parameter file "eedata", stored in EEPARAMS.h).
3663      - Refine debug-msg printing selection (3 new levels):
3664        debugMode  : controls printing of debug messages (sequence of S/R calls).
3665        debugLevel : controls printing of algorithm-relevant auxiliary/debug messages
3666         debLevZero =  0 ; /* level of disabled aux. msg printing */
3667         debLevA =  1 ; /* level of minimum  aux. msg printing */
3668         debLevB =  2 ; /* level of low aux. print (report read-file opening)*/
3669         debLevC =  3 ; /* level of moderate debug prt (most pkgs debug msg) */
3670         debLevD =  4 ; /* level of enhanced debug prt (add DEBUG_STATS prt) */
3671         debLevE =  5 ; /* level of extensive debug printing */
3672        New debugLevel default: with default debugMode value (=F),
3673          = 2 (debLevB) or = 1 (debLevA) in case ALLOW_AUTODIFF is defined.;
3674          and if debugMode=T, default debugLevel = 4 (debLevD).
3675        Relation with previous settings:
3676         debLevB (=2) corresponds to former debLevA (=1)
3677         debLevD (=4) corresponds to former debLevB (=2)
3678        Note:
3679         a) if debugLevel=0, skip WRITE_GRID call when nIter0 > 0 (same as before);
3680         b) default debugLevel=1 is convenient in AD runs (avoid many file opening msgs);
3681            to recover previous default, set debugLevel=2 (e.g. AD-test hs94.1x64x5)
3682      - Add new parameter (printResidualFreq, read from PARM02 namelist) to print
3683        detailed CG solvers convergence; off (=0) by default, except if debugLevel=5.
3684    o pkg/obcs:
3685      - change OBCSfixTopo default from True to False (should not change the results);
3686        keep OBCSfixTopo=T in verification-exp. seaice_obcs.
3687    o pkg/thsice:
3688      - fix bug in thsice_calc_thickn.F (was introduced in version 1.18) in
3689        2nd layer seaice sublimation (unlikely to happen)
3690      - use Interior mask for OBCS in thsice_advection.F (similar to what is
3691        done in gad_advection & seaice_advection).
3692    o adjoint:
3693      bug fix spotted by Gael Forget:
3694      seaice_advection and thsice_advection still had
3695      legacy CPP options to avoid CS corner updates for adjoint
3696    o pkg/seaice:
3697      => Change some of the defaults (2011/05/29):
3698         - change SEAICEuseFluxForm default (from False to True)
3699         - change DIFF1 default (from 0.004 m/s to 0. m/s)
3700         And print warnings if DIFF1 is not set in data.seaice and centered
3701          avection scheme is used without any diffusion.
3702      also:
3703      - fix seaice_diffusion calls in default AdvScheme part of seaice_advdiff.F;
3704      - set SEAICEdiffKh[] default in the same way as SEAICEadvSch[]
3705      - stop if DIFF1<>0 with SEAICEadvScheme <> 2, if DIFF1<>0 with any
3706        other non-zero SEAICEdiffKh[] diffusivity, if SEAICEadvSalt=T with
3707        #undef SEAICE_VARIABLE_SALINITY, if SEAICEadvAge=T with #undef SEAICE_AGE.
3708      update results of test exp.:
3709         lab_sea: output.fd (switch to AdvScheme=33 with diffKh=20)
3710             output.hb87, output_adm.evp (SEAICEuseFluxForm=T and diffKh=200)
3711             output_adm.noseaicedyn (SEAICEuseFluxForm=T)
3712         offline_exf_seaice: output.seaicetd, output_adm (SEAICEuseFluxForm=T)
3713         seaice_obcs: output (SEAICEuseFluxForm=T)
3714      and prescribe old default for SEAICEuseFluxForm (=F) and DIFF1 (=0.004)
3715          for standard fwd & AD lab_sea tests (to keep the same output).
3716    o pkg/seaice/seaice_growth.F:
3717      - use Ian Fenty's capping formulas for actual ice
3718      thickness thoughout EVOLUTION branch.
3719      - put treatment pathological case #2) in CPP brackets
3720      (ALLOW_AVOID_INFINITESIMAL_AREA, undef by default).
3721      - update global_ocean.cs32x15 and 1D_ocean_ice_colum results accordingly.
3722    o pkg/seaice:
3723      - seaice_diffusion.F : remove the min(DX,DY) factor permanently;
3724      pass the Laplacian diffusivity (in m^2/s) diffKh as a parameter;
3725      also pass fac as a param, which can be 1. (to update the tendency
3726      field) or the time step (to update the field itself).
3727      - seaice_advdiff.F: for multidim, call seaice_diffusion with
3728      e.g. SEAICEdiffKhHeff and with fac=1; for single-dim, call
3729      seaice_diffusion with e.g. SEAICEdiffKhHeff and with fac=time step.
3730      - SEAICE_PARAMS.h, seaice_readparms.F, seaice_check.F :
3731      hooks to handle SEAICEdiffKhHeff, SEAICEdiffKhArea, etc.
3732    o pkg/seaice:
3733      diffusion with centered advection scheme (diffus.F & advect.F):
3734      - simplify S/R DIFFUS (put deltaT & DIFF1 factor outside, move EXCH outside)
3735        to just compute the laplacian of input-field.
3736      - unroll k loop (harmonic,biharmonic diff) in advect.F to save 1 exch call.
3737      - fix flux-form version in diffus.F to conserve tracer.
3738      update output of lab_sea.fd & lab_sea.hb87 (1rst set of modif affects
3739       machine truncation) and lab_sea.salt_plume (conservative flux-form modif)
3740    
3741    checkpoint62y (2011/05/26)
3742    o pkg/seaice:
3743     - seaice_growth.F : in EVOLUTION branch, always include
3744       a_QSWbyATM_cover in qnet (as it should be).
3745     - verification/global_ocean.cs32x15 : update results accordingly
3746       (output.seaice.txt output_adm.seaice.txt).
3747    o pkg/seaice + obcs:
3748     - use maskInW & maskInS in multi-dim advection and biharmonic diffusion:
3749       equivalent of assuming no tracer gradient outside the OB region.
3750       update output of seaice_obcs (uses DIFF1 <>0 => biharmonic diffusion)
3751     - remove calls to OBCS_COPY_TRACER after EXCH calls (no longer needed
3752       after changes above);
3753     - obcs+seaice cleaning: apply seaice-tracer OB values to tracer field
3754       only at OB location (instead of over a band of OLx width).
3755    o pkg/seaice:
3756     - fix wrong indices in old (non Flux-Form) diffusion default S/R diffus.F
3757       (dxG(I+1, ...) changed to dxG(I, ...), no impact on Lat-Lon grid)
3758    o pkg/obcs:
3759      - split header file "OBCS.h" into 4 separated files:
3760        OBCS_PARAMS.h, OBCS_GRID.h, OBCS_FIELDS.h & OBCS_SEAICE.h
3761       Note: OBCS_PARAMS.h & OBCS_GRID.h can be included without OBCS_OPTIONS.h
3762         (contain no conditional statement which depends on OBCS options).
3763      - move "useOBCSYearlyFields" from "data.obcs" (hold in OBCS_PARAMS.h)
3764        to parameter file "data.exf", namelist EXF_NML_OBCS (in EXF_PARAM.h).
3765    o ctrl, cost, grdchk & autodiff pkgs:
3766      - make options file more standard (like other {PKG}_OPTIONS.h file but
3767        with AD_CONFIG.h); clean-up some of the included header files.
3768    o pkg/obcs:
3769      - do not mask tracer when applying OB (tracer == 0 could generate problems)
3770      - apply tracer OB values to tracer field only at OB location (instead of
3771        over a band of OLx width)
3772      - clean-up obcs_apply_w.F & obcs_apply_eta.F (since less calls to these S/R)
3773      - remove OBCS_MULTIDIM_OLD_VERSION code in gad_advection.F and remove
3774        obcs_apply_tloc.F & obcs_apply_sloc.F
3775    o obcs in model/src:
3776      - call OBCS_APPLY_W only if NonHydrostatic.
3777      - call OBCS_APPLY_ETA only if NonLinFreeSurf.
3778      - reset dEtaHdt and wVel to zero outside OB interior region ;
3779      - leave tracer unchanged outside OB interior region: This has no effect
3780        on the solution but just to prevent unrealistic tracer value outside OB.
3781      - zero out velocity outside OB interior region: This has no effect on
3782        the solution but just to prevent unrealistic velocity outside OB.
3783    o obcs and non-lin free-surf:
3784       move call to OBCS_APPLY_R_STAR from update_r_star.F to calc_r_star.F
3785       and call to OBCS_APPLY_SURF_DR from update_surf_dr.F to calc_surf_dr.F
3786       + add argument "etaFld" to OBCS_APPLY_R_STAR & OBCS_APPLY_SURF_DR:
3787       this fixes missing EXCH + get consistent eta OB value (+ fix restart).
3788       update results of test-exp. exp4(nlfs).
3789    o exp4 (nlfs) test-exp:
3790       use OBC for Eta at Western & Eastern OB (to test prescribing Eta
3791       with NonLin-FreeSurf); update output.nlfs.txt
3792    o obcs and 2d/3d solver norm:
3793       use interior masks (maskInC) to cancel out cg2d & cg3d matrix coeff at OB
3794       and outside OB interior region (will allow to place OB further inside the
3795       domain). Depending on the domain, can affects cg2d-Norm (previous
3796       cancellation outside OB was only partial), e.g. in exp4 & obcs_ctrl,
3797       and cg3d-Norm (previous Norm was computed before canceling OB terms),
3798       e.g. in tutorial_plume_on_slope.
3799      - update output of exp.: exp4 (x2), obcs_ctrl and tutorial_plume_on_slope.
3800    o pkg rbcs:
3801      - split RBCS.h into 3 files: RBCS_SIZE.h, RBCS_PARAMS.h & RBCS_FIELDS.h
3802      - add capability to apply relaxation to horizontal velocity uVel & vVel.
3803    o pkg/grdchk: add gradient check for control variable xx_shifwflx
3804    o pkg/shelfice/shelfice_init_fixed.F
3805      fix CPP-flag combinations
3806    o pkg/seaice: Merge iceage code of Pierre Rampal
3807      * update/change/correct ice age calculations
3808      * add age updates for pathological cases
3809      Probably needs more testing...
3810    
3811    checkpoint62x (2011/05/13)
3812    o pkg/mom_vecinv:
3813       high-order vorticity scheme: use interior masks (maskInW & S)
3814       to zero-out (outside OB) gradient of vorticity.
3815    o verification exp.:
3816       turn on "useEnergyConservingCoriolis" (better discretisation) in exp.
3817       hs94.128x64x5 and seaice_obcs ; update results.
3818    o pkg/obcs:
3819      fix bug in OBeta for YZ sections in obcs_exf_load.F
3820    o pkg/ctrl, pkg/shelfice, and optim:
3821      - add new control variable xx_shifwflx (fresh water flux underneath ice
3822        shelves). This is almost as tedious as obcs-ctrl, because the
3823        variables needs its own mask.
3824      - add a cost function term that penalizes the deviation of xx_shifwflx
3825        from the first guess (zero) in analogy to other control variables
3826    o pkg/shelfice:
3827      - start basic adjoint
3828    o pkg/ctrl:
3829      - remove extra 2D field "for good measure" when initializing in
3830        ctrl_set_globfld_[xy/xz/yz].F
3831      - replace hard coded precision 32 (a bug) in ctrl_map_ini_gen by ctrlprec
3832      - improve error messages in ctrl_set_unpack_*
3833    o OBC implementation in momentum:
3834       use interior masks (maskInC,W & S) in momentum S/R:
3835       - multiply divergence, tension and some del^i.u or del^j.v by maskInC
3836       - multiply del2u,del2v by maskInW/S (biharmonic viscosity)
3837       - multiply horiz. grad of vorticity by maskInW/S (in Leith scheme)
3838       - multiply gradient of wVel by maskInW/S in del2w calculation (NonHyd)
3839       Motivation: fix/clean implementation of OBC with biharmonic-viscosity
3840        (and also with Leith/Smagorinsky harmonic-viscosity).
3841       Update output of experiment dome and exp4 (+nlfs).
3842    o exp4 test-exp:
3843      - turn on: nonHydrostatic, exactConserv, viscA4 (with momDissip_In_AB=F)
3844        and prescribe time-varying OB (without pkg/exf) for zonal-velocity
3845        at Western & Eastern Boundaries (+/- 1 per-cent); Also prescribe
3846        time-varying OB at Western-side for wVel (NonHyd); update output.
3847      - add secondary set-up (.nlfs) using NonLin FreeSurf (z*) + mom_vecinv
3848        and biharmonic-viscosity ; also use prescribed time varying OB.
3849    o pkg/obcs:
3850      fix bug in OBWeta,OBWeta indices in obcs_apply_r_star.F
3851    o model/src:
3852      - fix startTime setting when baseTime<>0 & nIter0=0 are specified ;
3853      - initialise startTime & nIter0 with unlikely values: allows to set one
3854        from the other without ambiguity.
3855    o seaice_obcs test-exp.:
3856      add small diffK4T,S to test biharmonic diffusivity with OBCS ; update output.
3857    o pkg/obcs:
3858      - remove calls to OBCS_COPY_TRACER after EXCH for T,S & pTracer:
3859        no longer needed with maskInC,W,S in pkg/generic_advdiff.
3860    o pkg/seaice:
3861      - retired SEAICE_SALINITY and SEAICE_salinity in favor of
3862        SEAICE_VARIABLE_SALINITY and SIsalFRAC, respectively.
3863      - fixed bug in the initialization of sea ice salinity variable HSALT
3864        in seaice_init_varia.F  (removed dependence on ICE2WATR)
3865    o fizhi-cs test exp.:
3866       switch reference output convention for these 2 non-standard test-exp,
3867        from: pgi  6.1-5 on faulks (FC.6, -of linux_ia32_pgf77+authors_fc5)
3868          to: ifort 11.1 on baudelaire (FC.13, -of linux_amd64_ifort11)
3869       reason: faulks might get retired soon and pkg/fizhi has still Pb with gfortran
3870    o model/inc:
3871      - change type of PmEpR array (from _RS to _RL) to fix restart (with "-use_r4")
3872        of exp. global_ocean.90x40x15 (Suncronous time-stepping + Real-FW + NonLin-FS)
3873    o pkg/seaice:
3874      - fix calculation of saltFlux and saltPlumeFlux when using SEAICE_SALINITY
3875    o verification/lab_sea, 1D_ocean_ice_column, seaice_obcs, global_ocean.cs32x15
3876      - updated output*.txt files due to bug fixes in salt, saltPlumeFlux,
3877        and initial HSALT
3878    
3879    checkpoint62w (2011/04/26)
3880    o pkg/mom_fluxform:
3881      - fix calculation of del2u & del2v (no-slip BC) when using Non-Lin Free-Surf.
3882      - use parameter "sideDragFactor" in no-slip BC side-drag part.
3883      - update output of exp. global_ocean.90x40x15
3884    o pkg/mom_vecinv:
3885      mask del2u & del2v (no effect on results, but cleaner & closer to mom_fluxform)
3886    o update seaice exp.:
3887      use more consistent parameter values (remove "backward compatability only":
3888       ICE2WATR, SEAICE_lhSublim, SEAICE_cpAir, SEAICE_rhoAir + set rhoConstFresh)
3889      related to thermodynamics seaice. Update output (fwd+AD) of exp.:
3890       1D_ocean_ice_column (x2), lab_sea (x8), ioffline_exf_seaice (x2) & seaice_obcs
3891    o update test-exp global_ocean.90x40x15:
3892      o use default CD_CODE_OPTIONS file (Adams-Bashforth on CD Mom & Coriolis).
3893      o increase Overlap size from 2 to 3 (to allow to test bi-harmonic Visc.)
3894      o new pickup-files from a 100.yr run with pkg/down_slope (input.dwnslp params)
3895      o turn on zStar & viscA4 in standard set-up (dir input/)
3896        and update output files: output.txt & output.dwnslp.txt
3897    o new AD-test experiment: obcs_ctrl
3898      (From Matt MITgcm_Contrib/SOSE/BoxAdj) to test OBCS as control vector.
3899    o pkg/dic:
3900      fix two bugs in handling water vapour pressure in carbonate chemistry
3901      and air-sea fluxes. Found by Val Bennington and Galen McKinley
3902      (add DIC Option = WATERVAP_BUG to recover old results)
3903      update output of tutorial_global_oce_biogeo (fwd+AD) & tutorial_dic_adjoffline
3904    o adding allowInteriorFreezing option to check for water below freezing point
3905      at depth and bring the negative heat anomaly to the surface level
3906    o pkgs _fields_load:
3907      - extend GET_PERIODIC_INTERVAL to deal with non-periodic case (from pkg/rbcs)
3908      - use new S/R GET_PERIODIC_INTERVAL in pkgs:
3909        bulk_force, cheapaml, cfc, dic, obcs (+ ctrl/ctrl_get_gen_rec), offline and
3910        rbcs to get interpolation weights and time reccord number.
3911      - fix multi-threading in aim_fields_load.F
3912      - apply EXCH to temp arrays [0,1] after reading in dic_fields_load.F
3913    o external_fields_load:
3914      new S/R GET_PERIODIC_INTERVAL to calculate which time-record (and linear
3915       interpolation weights) to use in a periodic time-series ; do not divide by
3916       time-step to convert to integer:
3917       - this fixes case where externForcingPeriod is not multiple of time-step
3918          (Thanks to Christopher L. Wolfe)
3919       - this fixes case where externForcingPeriod is an odd multiple of time-step
3920         (was wrong by half of time-step); update results of tutorial_global_oce_in_p.
3921      store index of time-record which is currently loaded:
3922       - works without any assumption on sequence of calls to EXTERNAL_FIELDS_LOAD ;
3923       - needed for the adjoint but not yet used because of extensive recomputations;
3924         (to be fixed soon)
3925    
3926    checkpoint62v (2011/04/02)
3927    o verification/1D_ocean_ice_column added to test Ian Fenty's
3928      pkg/seaice_growth.F modifications for improving sea ice code differentiability
3929    o update output of exp4, internal_wave, seaice_obcs, tutorial_plume_on_slope
3930      (new velocity statistics after changing maskInW & maskInS definition)
3931    o pkg/generic_advdiff with OBCS:
3932      use maksInW & maskInS in advective flux and in biharmonic diffusion calculation:
3933      equivalent to assumption of no tracer gradient outside the OB region.
3934      This will affect the results if using obcs+biharmonic diffusion.
3935      update output_adm.txt of experiment bottom_ctrl_5x5 (not expected since no obc)
3936    o pkg/obcs:
3937      change definition of maskInW & maskInS: leave OB edges inside (maskIn=1)
3938      (e.g., maskInW(OB_Ie)=1 ) so that velocity normal-component at OB is still
3939      in Interior region. No impact on solution but affects Velocity monitor stats.
3940    o pkg/ptracers (adjoint)
3941      New option AUTODIFF_PTRACERS_SPLIT_FILES for writing separate
3942      tape file for each tracer
3943    o model/inc/src and pkg/autodiff: add parameters that allow to turn
3944      of parts of the adjoint code at run time. For now, there are only
3945      useKPPinAdMode, useGMrediInAdMode, and useSEAICEinAdMode. These
3946      parameters are set in data.pkg.
3947      This is the lazy coward's version of doing this, but still useful for
3948      debugging. In order to do it right, everything needs to be moved to
3949      pkg/autodiff.
3950    o pkg/autodiff: fix global_sum_tile_ad.F by resetting adsumPhi at
3951      the end; this fixes the adjoint balancing code for open boundaries.
3952    o pkg/ctrl:
3953      - change behavior of xx_${varname}period to be analogous to exf-conventions:
3954        xx_${varname}period =   0.,  means time-independent control part
3955        xx_${varname}period = -12., means one-year-periodic monthly control part
3956      - introduce helper routine ctrl_init_rec (part of ctrl_init.F) to
3957        clean up ctrl_init a little, remove unused variables
3958      - ctrl_init: fixed the handling of the start/endrec for obcs-variables
3959      - move "call cal_GetMonthsRec" from s/r ctrl_get_gen to s/r ctrl_get_gen_rec
3960    
3961    checkpoint62u (2011/03/15)
3962    o model/src:
3963      - for the adjoint, change NonLin-FreeSurf initialisation sequence: fill-in
3964        h0Fac from INITIALISE_FIXED and reset hFac to h0Fac in INITIALISE_VARIA ;
3965      - in initialise_varia.F (except for ALLOW_DEPTH_CONTROL) remove 2nd call to
3966        INI_DEPTHS, INI_MASKS_ETC & INI_LINEAR_PHISURF.
3967    o pkg/ctrl/obcs/ecco:
3968      - remove obsolete, unused, and partially broken code:
3969        ctrl_obcsvol/ctrl_obcsbal/ctrl_volflux and code within
3970        ALLOW_CTRL_OBCS_BALANCE
3971      - put a stop statement into ecco/cost_obcsvol.F, but also add
3972        cost_obcsvol to ecco_ad_diff.list
3973    o pkg/ecco: fix counting cost function contributions for obcs (code
3974      by Matt M.) and diffkr for diagnostics
3975    o pkg/ecco, pkg/ctrl, pkg/grdchk:
3976      add cost penalty terms for initial uvel, vvel, eta controls
3977      and I/O for prior error files
3978    o pkg/mdsio:
3979       move mds_check4file.F from eesupp/src to mdsio_check4file.F ; add option
3980       (new argument) to check for tiled file in mdsioLocalDir : this fix the
3981       restart from pickup_som , pickup_dic (& dic_co2atm) with mdsioLocalDir.
3982    o pkg/ctrl:
3983     - ctrl_obcsbal.F, ctrl_obcsvol.F: replace last calls of ctrl_getrec by
3984       ctrl_get_gen_rec, put a stop statement into ctrl_getrec. Remove
3985       unused and superfluous variables
3986     - ctrl_get_gen_rec.F: catch the case of xx_genperiod=0.
3987    o pkg/ecco
3988     - enable adjoint of Stevens OB
3989    o pkg/ctrl/ecco/grdchk:
3990      - remove global declaration of tmpfldx/yz and tmpfldx/yz2.
3991        Fortunately, we do not have any tests for the numerous cpp-flagged
3992        option of "obcs as control parameters" so we will never know
3993        if this is an improvement (but at least now things compile).
3994      - remove an obsolete initialization from ecco_cost_init_barfiles.F
3995      - fix some problems within never used ifdefs to make the code compile
3996    o pkg/obcs:
3997     - Refine Interior mask definition to work with more complex OB (e.g.
3998       if OB_Ie < OB_Iw); In case default setting is not sufficient, allows to
3999       read in Interior mask from file. Check if Interior mask is consistent
4000       with OB list of indices.
4001    o pkg/seaice
4002     - beginning code for a seaice tracer package,
4003       but currently only used for seaice age: SEAICE_AGE
4004       SEAICE_num = 4
4005       iTracer = 1: area-weighted ice age
4006               = 2: volume-weighted ice age
4007               = 3, 4: template for one-year vs. multi-year ice
4008       data.seaice has new namelist SEAICE_PARM03 for arrays related to
4009       SEAICE_num
4010    
4011    checkpoint62t (2011/03/05)
4012    o pkg/obcs:
4013     - obcs_apply_uv.F: change to a 2 steps method, first tangential component;
4014       then normal component. This ensures that the normal component is set
4015       correctly even when it conficts with tangential setting from an other OB.
4016       Affects results of test-experiment seaice_obcs: update the output.txt
4017    o pkg/obcs:
4018     - add code to monitor statistics of dynamical fields at OB.
4019     - take OBCS_BALANCE code out of obcs_calc.F into new S/R OBCS_BALANCE_FLOW :
4020       - fix to OBCS_BALANCE code (right hFac ; deal with simple OB intersection).
4021       - change default: balance the Net inflow through all OB (instead of balancing
4022         each OB separately); keep the old method if setting OBC_balanceFacX < 0.
4023     - switch on useOBCSbalance in dome experiment: only correct Western OB outflow
4024       to match Nortern OB inflow (OBCS_balanceFacN=0).
4025    o pkg/seaice:
4026     - redefined actual sea ice age to be ICEAGE/HEFF ifdef SEAICE_AGE_VOL
4027    o pkg/seaice (seaice_growth v 1.113):
4028     - reverting seaice_growth to v 1.111 in order to have code with exact bit
4029       compatibility with MITgcm_contrib/ifenty/Fenty_seaice_thermo_code_merge
4030       CPP option SEAICE_OCN_MELT_ACT_ON_AREA removed in v 1.112 is reintroduced
4031       runtime flag SEAICEareaFormula is kept but is inactive
4032    o model/src:
4033     - add new param to scale curvilinear grid distance and area when using
4034       a different sphere radius from the grid-files.
4035     - test/check multi-threads EXCH applied to local variable (cg2d_x)
4036    o adjoint:
4037     - enable adjoint of Stevens OB
4038     - add dummy_in_dynamics to enable extraction of ADJrhoinsitu
4039       (a bit delicate because of potentially modified adj. common block structure;
4040       current switch is ALLOW_AUTODIFF_MONITOR_DIAG, could be changed later)
4041    
4042    checkpoint62s (2011/02/15)
4043    o pkg/seaice (seaice_growth v 1.112):
4044     - introduce SEAICEareaFormula run time parameter, which selects the recipe for
4045       computing the ice cover tendency from effective thickness tendencies. Include
4046       Ian Fenty's formula.
4047     - remove 'undef SEAICE_OCN_MELT_ACT_ON_AREA' which may now be achieved using
4048       SEAICEareaFormula.
4049     - simplify notations for the various d_HEFF/d_AREA terms.
4050    o pkg/gmredi:
4051     - add Boundary-Value-Problem bolus transport (Ferrari etal, OM 2010) code
4052       from Christopher Wolfe (UCSD); add partial cell factor in vertical derivative;
4053       add a verification test-run (front_relax.bvp) to test GM_useBVP.
4054    o pkg/seaice (seaice_growth v 1.111):
4055     - for SEAICE_DO_OPEN_WATER_GROWTH, replace Gael's implementation with Ian's.
4056     - the new SEAICE_DO_OPEN_WATER_MELT allows open-water air-sea heat fluxes to
4057       also melt ice.
4058    o pkg/seaice:
4059     - McPhee formula for Ice-Ocean fluxes (provided by Ian Fenty).
4060     - can be used by #define MCPHEE_OCEAN_ICE_HEAT_FLUX in SEAICE_OPTIONS.h
4061    o pkg/cheapaml:
4062     - from Nico Wienders: New version of this package.
4063    o pkg/flt:
4064     - add CPP options to prevent floats to re-enter the opposite side of
4065       a periodic domain (default: keep periodicity)
4066    o pkg/gmredi:
4067     - apply exchange to GM_PsiX,GM_PsiY to get valid values near CS-corners
4068       (needed for multi-dim advection).
4069     - switch on GM Advective form in global_ocean.cs32x15 and update output.txt
4070    o model/src:
4071     - fix wrong re-setting of addMass array (ALLOW_ADDFLUID) for atmospheric run.
4072    o tutorial_tracer_adjsens
4073     - extend to NLFS and replace maskC by hFacC
4074       (change reference output accordingly)
4075    
4076    checkpoint62r (2011/01/24)
4077    o testreport:
4078     - add option -deloutp (-do) to remove output file after successful run
4079     - add option -mfile (-mf) for MPI machile-file and for each test-exp,
4080       extract exact list of procs from this file ; adjust COMMAND by
4081       replacing TR_MFILE & TR_NPROC with local machile-file & Nb of MPI procs.
4082    o pkg/ecco: replace old ineffective way of penalizing deviations from
4083      first guess (of obcs) with code by Matt Mazloff
4084    o pkg/ctrl: add code that allows the use of ALLOW_OBCS?_CONTROL without
4085      exf/cal
4086      - ctrl_init: fix initialisation (computation of diffrec) for obcs-ctrl
4087        and handle case of obcs?period == 0
4088        Not affected by these changes: There is still an inconsistency in
4089        the computation of start/endrec for the obcs variables for ALLOW_CAL
4090        defined (see comment by Menemenlis, 7-Mar-2003)
4091      - make S/R ctrl_get_gen_rec return something meaningful even if
4092        ALLOW_CAL is not defined
4093      - ctrl_getobcs?: simplify code so that it does not need to use
4094                       S/R exf_swapfields
4095    o testreport:
4096       allow to test MPI with different number of processors for each experiment:
4097       create file "SIZE.h.mpi" in each build dir.
4098       Note: update of "-command" argument not yet implemented.
4099    o model/src, pkg/autodiff, pkg/ecco, pkg/seaice:
4100      alleviate the need for additional 3D tapes when using
4101      the non-inear free surface in the adjoint. This is done
4102      by adding an 'update' of hfacc etc. to their current
4103      value at the beginning of forward_step.F.
4104    o pkg/seaice
4105      seaice_lsr: move stress-divergence computations out of outer pseudo-
4106      timestepping loop
4107    o pkg/obcs/obcs_prescribe_read.F: move 'CALL OBCS_EXTERNAL_FIELDS_LOAD'
4108      up, so that the calls of the ctrl_* subroutines are really at the end
4109      of the routine.
4110    o pkg/gmredi:
4111      allow to specify a 2-D horizontal map and a 1-D vertical profil
4112      as scaling factor for Isopycnal diffusivity (Redi) and GM diffusivity.
4113    o pkg/seaice:
4114      move lsr iterations from seaice_dynsolver to seaice_lsr.
4115    o pkg/seaice:
4116      reduce memory footprint of seaice mutldim advection tapes,
4117      by using a 2D tape independent of the generic_advdiff ones,
4118      and setting GAD_AREA=1 etc. rather than GAD_AREA=101 etc.
4119    
4120    checkpoint62q (2010/12/29)
4121    o model/src:
4122      - check horizontal grid-spacing for unset or zero/negative values.
4123      - change AD test hs94.1x64x5 to be truly a 2-D set-up.
4124    o pkg/flt:
4125      - use (recent) mdsio S/R MDS_READVEC_LOC instead of local FLT_MDSREADVECTOR
4126      - precision of input and output files set according to readBinaryPrec
4127        and writeBinaryPrec (previously always 64.b), pickup remains at 64 bits.
4128      - initial float position from tiled file was not converted to index space
4129        (looks like a bug): fixed to make it similar to initial pos. global file.
4130    o global_ocean.cs32x15:
4131       change SIZE.h of AD set-up to get same tiling as with MPI.
4132       Update output_adm, output_adm.thsice (pass@14) & output_adm.seaice (fail@11)
4133    o model/src:
4134       add flag to control printing of domain fields (bathymetry, hFac ...) in
4135       ini_mask_etc (call to plot_fieds_xy*).
4136    o pkg/thsice:
4137       if useEXF, some forcing fields are not valid in overlap: fixed by computing
4138       over the interior only + apply EXCH at the end (like with SEAICE advection).
4139    o pkg/mdsio:
4140      - add 2 arguments to S/R MDS_PASS_R4/8toRL/S for overlap size of buffer
4141        to copy to/from, so that it can be used to replace MDS_PASS_WH_R8toRL/RS.
4142      - change barrier call for safe multi-threads access to 3-D shared buffer.
4143      - MDS_READ/WRITEVEC_LOC use buffers from MDSIO_BUFF_3D.h (instead of local ones)
4144      - replace call to MDS_PASS_WH_R4/8toRL with call to MDS_PASS_R4/8toRL and
4145        remove the 4 S/R MDS_PASS_WH_R4/8toRL/S.
4146    o pkg/flt:
4147      - add fourth-order Runge-Kutta integration
4148      - add basic exch2 support (only 1 facet supported so far!)
4149    o pkg/mdsio+rw:
4150      new S/R to read local (or tile independent) vector (read counterpart of
4151       mds_writevec_loc, and front-end write_glvec_rl/rs).
4152    o global_ocean.cs32x15: additional input_ad.seaice experiment
4153        that uses pkg/seaice rather than pkg/thsice.
4154        (using multidim advection for seaice)
4155    o towards more F95 syntax for array specification in namelist:
4156      - change "data.diagnostics" (data.ptracers was changed before checkpoint62p)
4157        of all verification experiments.
4158           e.g.:    line: fields(1,3)='ETAN    ','ETANSQ  ',
4159          was changed to: fields(1:2,3)='ETAN    ','ETANSQ  ',
4160      - finish adding "-DNML_EXTENDED_F77" to DEFINES list in pgf77 and g77 optfiles
4161    o global_ocean.cs32x15: additional input.seaice experiment
4162        that uses pkg/seaice rather than pkg/thsice.
4163    
4164    checkpoint62p (2010/12/17)
4165    o pkg/thsice: rename (ad tape index) iicekey as ticekey, and move it
4166        to THSICE_SIZE.h to avoid conflict with pkg/seaice.
4167    o pkg/seaice: add seaice_diffusion.f seaice_map_thsice.f to adjoint.
4168        allow for use of multim. advection in seaice adjoint.
4169    o pkg/seaice: add diagnostics for snow precipitation and sublimation flux
4170      - first attempt to close budgets by taking into account the freshwater
4171        flux implied by the sublimation of snow and ice. So far only the
4172        volume budget is closed, turn on with soon-to-be-retired-again CPP-Flag
4173        SEAICE_ADD_SUBLIMATION_TO_FWBUDGET
4174    o eesupp/src:
4175      new S/R with new option (NML_EXTENDED_F77) to change array specification
4176      from F95 standard to commonly accepted extended F77 form.
4177      This would allow to use F95 syntax in namelist (needed with gfortran 4.4.5)
4178      and to revert back to the original syntax (with -DNML_EXTENDED_F77)
4179      for less tolerant f77 compiler (e.g., pgf77, g77).
4180    o globalFiles:
4181      commented out in parameter file "data" since it's not safe with MPI
4182      (e.g., wrong on aces); keep it if useSingleCpuIO=T (but not doing much
4183      in this case); no longer commented out in restart test (tst_2+2).
4184    o add adTapeDir to specify a special directory where adjoint tapes are
4185      written/read (adread_adwrite.F). adTapeDir is specified in data/PARM05
4186      and cannot be used together with mdsioLocalDir.
4187    o nesting pkgs:
4188      - packages_init_variables : put call to OBCS_INIT_VARIABLES in last position
4189      - update Gianmaria's Nesting pkgs (from Contrib/nesting_sannino)
4190      - add parameter files + utils dir + output from short run on beagle.
4191    o pkg/seaice:
4192        fix seaice_growth.F store directives; update results of exp. lab_sea.ad
4193    o pkg/seaice: explicitly store tsurfloc in seaice_solve4temp.F to avoid
4194      unnecessary copying in adjoint code, requires new parameter NMAX_ITER
4195    
4196    checkpoint62o (2010/11/25)
4197    o pkg/exf:
4198      - change CPP option EXF_VERBOSE to run-time logical param exf_verbose.
4199    o pkg/seaice:
4200      - seaice_ocean_stress: split a loop for better vectorization of the
4201        adjoint code
4202      - seaice_growth.F: fix bug in conservation of freshwater connected to
4203        capping of heff, put contribution into d_HEFFbyNEG
4204      - replace irritating parameters SEAICE_latentWater/Ice and SEAICE_sensHeat
4205        by something more sensible (parameters that are what their name implies)
4206      - change some defaults, so that by default exf-parameters are used for
4207        things like rhoAir, cpAir,latent/sensible heat parameters, in order
4208        to reproduce the old results, many data.seaice now contain funny values
4209        for cpAir and latent heat of sublimation
4210    o packages_readparms.F: move exf_readparms up in line so that
4211        exf-parameters are visible for other packages (e.g. seaice)
4212    o debugMode & debugLevel=2:
4213      - differentiate between debugMode & debugLevel=2:
4214        debugMode: controls printing of debug messages (sequence of S/R calls).
4215        debugLevel: controls printing of algorithm intermediate results and stats.
4216      - remove "if debugLevel=2 => debugMode" but keep "debugMode =>  debugLevel=2";
4217        => allows to print debug-stats without all sequence of call messages.
4218      - switch control of debug print from debugLevel to debugMode in many S/R.
4219    o pkg/obcs (obcs-sponge):
4220        fix bug that was introduced on Oct 25 (in dynamics.F v1.151): put back the
4221        call to OBCS_PRESCRIBE_EXCHANGES (need to exch gU,gV when using obcs-sponge)
4222    o pkg/generic_advdiff:
4223      - record overlap minimum size for each advection scheme;
4224      - refine criteria on overlap minimum size;
4225      - check and stop (in gad_check) if overlap size is too small.
4226    o pkg/obcs:
4227      - with ptracers: remove multiple calls to obcs_apply_ptracer (only done
4228        once, in ptracers_implicit.F)
4229      - with seaice: remove test on empty file name in obcs_apply_seaice (always
4230        apply OB values when tile has OB)
4231    o model/src, coriolis setting:
4232      - integer parameter "selectCoriMap" (=0,1,2) replaces 3 logical
4233        useConstantF, useBetaPlaneF, useSphereF ; can now read coriolis from
4234        files (selectCoriMap=3) with any grid.
4235      - add parameter "fPrime" for constant second Coriolis coeff (default=0).
4236    o pkg/seaice/seaice_growth.F:
4237        a few cosmetic changes that reduce the number of lines of code
4238    o pkg/obcs: add boundary conditions following Stevens (1990)
4239      - the code follows old MOM/NAOSIM code
4240      - so far it is only implemented for the eastern and western boundaries
4241        and NOT for pTracers
4242    o pkg/rbcs:
4243      - replace rbcsInIter by rbcsForcingOffset, the time in seconds at the
4244        beginning of the first rbcs forcing period.
4245      - add option rbcsSingleTimeFiles that makes rbcs read forcing data like the
4246        offline package, i.e., one file per time, labeled by iteration number;
4247        deltaTrbcs sets the timestep with which the data was generated;
4248        rbcsIter0 is the forcing iteration corresponding to rbcsForcingOffset.
4249      - rbcsForcingCycle=0 makes forcing non-cyclic.
4250      - make arithmetic safe for negative times and odd forcing periods.
4251    
4252    checkpoint62n (2010/11/09)
4253    o pkg/seaice:
4254        fix masking in free-drift S/R ; update results of exp. lab_sea.fd
4255    o pkg/obcs:
4256       New S/R to copy tracer value from the OB location to narrow band region
4257        (width = same as overlap) beyond the OB: preserve OB value (needed for
4258        high-order scheme) which were overwritten by EXCH call if in overlap
4259        region. Applied to theta, salt, ptracer and advected seaice variables.
4260       With seaice: use maskInC in similar way as in gad_advection.F,
4261        in seaice_advection.F and advect.F.
4262       Update output of experiment seaice_obcs and change exp4 to test OBCS with
4263        4th order Adv.Scheme. for pasive salt and ptracer.
4264    o tools/genmake2:
4265      - when looking for an optfile (not specified), only search for Fortran compiler
4266        (remove sym-link test + setting of CPP + makedepend check + C-compiler check)
4267      - in get_fortran_c_namemangling: use "$CC $CFLAG" to compile C test programm
4268        (instead of "$MAKE genmake_test.o" since an existing Makefile can be wrong)
4269      - set default for CPP to "cpp -traditional -P" (was the case without specifying
4270        an optfile, but otherwise default was just "cpp".
4271      - comment out PLATFORM=$p_PLATFORM (no idea where p_PLATFORM comes from)
4272      - when "CC" is not set in the optfile, look for possible C compiler
4273        (instead of just setting CC=cc)
4274      - put back version v.169 modif (from 2008/02/15), was dropped in v.173 changes:
4275        => add a ".F" to ".o" rule for source files with no "#include" (such as
4276           port_rand.F); otherwise, default ignores FOPTIM and just uses FFLAGS.
4277      - move gfortran before g77 in list of possible Fortran compiler (consistent
4278        with reference compiler switch from g77 to gfortran)
4279    o pkg/seaice:
4280      o remove SEAICE_OLD_AND_BAD_DISCRETIZATION-code, add a test to
4281        seaice_check that stops the model, when the CPP flag is used.
4282      o seaice_growth.F: make capping of ice volume conserving by returning the
4283        capped ice as freshwater to EmPmR. This does not change the verification
4284        experiments but will change runs where the capping is acutally active
4285    o change reference platform+compiler from faulks+g77 to baudelaire+gfortran
4286      (except the 2 fizhi test exp.); update output of exp.: bottom_ctrl_5x5,
4287         global_ocean.cs32x15 (icedyn, thsice, AD thsice), global_ocean_ebm (AD),
4288         lab_sea (fd, hb87, salt_plume), MLAdjust (3/5) and vermix (dd)
4289    o tools/genmake2:
4290      - merge genmake_warnings & genmake_errors into 1 log file: "genmake.log")
4291      - change DUMPSTATE default to false (can use "-ds" option to switch it to T)
4292      - clean previous genmake log files before anything else.
4293      - change Makefile to remove testreport log files (*.tr_log) and genmake log
4294        files only with "CLEAN" target (instead of "Clean");
4295    o pkg/generic_advdiff:
4296      Change OBCS in multiDim advection (gad_advection.F):
4297       Use maskInC to prevent intermediate update of tracer-field in OB regions,
4298       thus keeping current-time-step OB values; and remove the call to OBCS_APPLY
4299       which were applying future time-step OB values.
4300      This way, all explicit calculations use current-time-step OB values
4301       (simpler and more consistent).
4302      Affects results when set-up uses time-varying OBC and multi-dim advection;
4303       update output of experiment seaice_obcs.
4304    o pkg/seaice:
4305      move OPTIONS (formerly locally defined) to SEAICE_OPTIONS.h:
4306       this includes SEAICE_GROWTH_LEGACY (+ SEAICE_DO_OPEN_WATER_GROWTH &
4307         SEAICE_OCN_MELT_ACT_ON_AREA ) and SEAICE_SOLVE4TEMP_LEGACY.
4308      Default (pkg/seaice/SEAICE_OPTIONS.h) is to define SEAICE_SOLVE4TEMP_LEGACY
4309       but leave SEAICE_GROWTH_LEGACY undef ; For now, keep verification exp
4310       unchanged (SEAICE_GROWTH_LEGACY defined in */code*/SEAICE_OPTIONS.h)
4311    o pkg aim (2010/10/26):
4312      - Introduce ALLOW_INSOLATION, moving toward a more general incoming solar radiation
4313        formulation with obliquity, eccentricity, ... as run-time parameters,
4314      - Introduce diagnostics for top-of-the-atmaophere incoming solar radiation and
4315        upward shortwave radition at the surface (all-sky and clear-sky).
4316    o pkg/obcs:
4317      - writing sections with globalFiles=T does not work: switch to tiled-files
4318        when writing sections for OBCS (change pkg/rw/write_rec.F accordingly).
4319      - fix index bug (OB_Ie -> OB_Iw_) in obcs_apply_uvice.F
4320      - apply OBCS_SEAICE_COMPUTE_UVICE to both uice and vice at all obcs
4321    
4322    checkpoint62m (2010/10/21)
4323    o pkg/seaice: vectorize seaice_solve4temp.F
4324      - move iterations loops outside of i/j-loops
4325      - requires 2D arrays for TB and effConduct
4326      - add 2D iceOrNot to replace HICE_ACTUAL.GT.0, as HICE_ACTUAL is
4327        modified in this routine
4328      - a little bit of clean up, adjusting indentation, etc.
4329      - replaced a few TEN**a by exp(a*log(10.)) in new code for better
4330        performance and '**TWO' by '**2' (because TWO is a float),
4331        replaced ONE, ZERO
4332    o eesupp/src:
4333       fix flow dir for exch1_z_RX_cube, exch1_uv_RX_cube & exch1_bg_RX_cube
4334    o pkg/seaice/seaice_growth.F
4335      Revision 1.89 of seaice_growth.F completes the overall october 2010 revision and
4336      merging process. The merged routine has two branches, and one activates the 'evolution'
4337      branch by setting SEAICE_GROWTH_LEGACY to undef (at the top of the routine for now).
4338      In summary, here is what the '10/10 revision' did consist of
4339        part 1: seaice_growth.F revisions 1.71 to 1.75
4340          - Preliminary seaice_growth.F clean-up, keeping test results strictly unchanged.
4341            The emphasis here was on improving readability (e.g. by trying to use meaningful
4342            variable names) and modularity (e.g. by adding arrays to store heff etc. updates).
4343        part 1.5:
4344          - revising the lab_sea experiment to make it a more useful (i.e. stable
4345            and representative of an actual model run). This was done by generating a
4346            (winter) pickup to start from, switching back the main experiment dynamic
4347            solver from evp to lsr, having one of the experiments use the free drift solution.
4348        part 2: seaice_growth.F revisions 1.76 to 1.85
4349          - Sorting out hard-coded constants that prevented heat and fresh water conservation.
4350          - Sorting out the various fields units and sign (set early on and reset at the end)
4351            to avoid numerous scalings/re-scalings. By v1.85 the basic unit for ice, heat and
4352            fresh water stock is 'effective ice meters', and >0 implies more ice/snow.
4353          - Using tendency terms arrays (d_HEFF* etc.) to alleviate remaining code locks,
4354            and simplifying logical expressions to further improve readibility.
4355        part 3: seaice_growth.F revisions 1.86 to 1.89
4356          - Re-organize the blocks of code more logically.
4357          - Merging the '_if.F' pieces that add something new.
4358    o pkg/thsice:
4359      - vectorize thsice_solve4temp and thsice_get_exf.
4360        Problem: thsice_solve4temp has an unvectorizable statement that
4361        might also be problematic for TAF
4362      - thsice_get_exf: add the ALLOW_BULK_LARGEYEAGER04 CPP-flag. This
4363        does not change the verifcation experiment, but will change all
4364        experiments that have this flag undefined (not tested in verification);
4365        a little reorganization to save a few 2D fields and recomputations
4366      - 1st step of revisiting thsice adjoint (major recomp. sorted out)
4367      - 2nd step:  fix some store dirs
4368        o seems to work somewhat, i.e. using ifort but not g77
4369        o likely cause are incomplete init. or recomputation
4370        o start verification/global_ocean.cs32x15/input_ad.thsice
4371    o pkg/obcs: add support for exch2
4372      - the position of the boundary and prescribed values are specified using
4373        a global domain with exch2 facets stacked
4374        - in x for N,S boundaries (like W2_mapIO=-1)
4375        - in y for E,W boundaries (so E,W boundaries do not overlap)
4376    o pkg/mdsio: add support for writing global sections with exch2
4377        file layout is as for obcs described above:
4378        - for x-z sections, facets are stacked in x (like W2_mapIO=-1)
4379        - for y-z sections, facets are stacked in y
4380    o pkg/thsice:
4381       - change a few routines for better vectorization: thsice_albedo.F,
4382         thsice_step_temp.F, and in thsice_calc_thickn.F. Results are
4383         not affected, but in particular the latter routine has changed
4384         dramatically (not necessarily easier to read now).
4385       - re-arrange calculation in THSICE_SOLVE4TEMP: move outside of i,j loops
4386       iteration loop and call to S/R THSICE_GET_BULKF & THSICE_GET_EXF.
4387    o verification/lab_sea:
4388      - overhaul of the forward model experiments. The main motivation
4389        for this revision is that lab_sea has proven quite fragile (when
4390        changing the sea-ice code, and switching platforms) to a point
4391        when failures were very hard to attribute to specific code problems.
4392      - the suspected reason for this fragility is noise amplification by evp so,
4393        to start with, we decided to replace evp with lsr in the main experiment.
4394      - the input.lsr experiment thus became obsolete and was removed.
4395      - it was replaced with the input.fd experiment that uses an
4396        analytical "free drift" solution as the ice velocity field.
4397      - Taken together, input (lsr), input.fd (free drift) and input.hb87 (evp)
4398        will hopefully allow us to discriminate problems due to dynamic solvers
4399        from problems due to the thermodynamic code. input.salt_plume (lsr) allows
4400        us to test additional options, along with the salt plume package.
4401      - Finally a pickup was generated (at the end of a one year run) to
4402        make the tests more representative of an actual model run. Previously
4403        the tests starting point was a 1m thickness of ice everywhere.
4404    o pkg/seaice:
4405      - introducing S\R seaice_freedrift.F that compute the
4406        analytical solution to an approximate ice momentum
4407        equation (i.e. the simple stress/coriolis balance).
4408      - define SEAICE_ALLOW_FREEDRIFT to trigger the computation
4409        of the free drift velocity field, and enable its use.
4410        To actually use the free drift solution as the model ice
4411        velocity field set SEAICEuseFREEDRIFT to .TRUE. in data.seaice.
4412    o move "useOASIS" from PARAMS.h to EEPARAMS.h and read it from "eedata"
4413    
4414    checkpoint62l (2010/10/04)
4415    o pkg/seaice:
4416      -fix the USE_ORIGINAL_SBI version (for variable freezing point);
4417      -use "celsius2K" in SEAICE_VARIABLE_FREEZING_POINT and in new
4418       version (with USE_ORIGINAL_SBI undef);
4419    o add hooks for new packages OASIS, the package will follow
4420      (hooks exclude the seaice pkg for now)
4421    o pkg/autodiff: ALLOW_AUTODIFF_WHTAPEIO
4422      Option to use mdsio_read_whalos.F/mdsio_write_whalos.F,
4423      rather than mdsio_readvector.F/mdsio_writevector.F, within
4424      adread_adwrite.F to read/write adjoint-related tapes to disk.
4425    o eesupp and pkg/mdsio: ALLOW_WHIO
4426      Option to write/read 2D fields to files including tiles halos.
4427      The main purpose is for adjoint related "tape I/O".
4428      The secondary purpose is for debugging phases.
4429      A word on those rather specifically intended purposes.
4430      The code was meant to be stripped down to the bare minimum.
4431      Typically, there is a unique and basic mapping to the global
4432      buffer (tile by tile, then proc by proc, then level by level), and
4433      byteswaps and meta-files are omitted. Indeed the (*_WH*) code is not
4434      meant to generate user friendly outputs of various shapes and forms.
4435      Rather it is intended, for the knowledgeabale developers,
4436      to be largely independent of the many mdsio options, to allow
4437      outputs of tiles+halos in debugging phases and in adjoint runs,
4438      and to allow some flexibility in tuning (adoint) I/O depending on each
4439      file system behavior. With regard to tuning, most of the potential knobs
4440      (to leave files open, to allocate the I/O indep. of usesinglecpuio,
4441      to specify directories, to specify the typical size of I/O calls, etc.)
4442      are not yet included, and will be added if they prove useful.
4443    o pkg/seaice:
4444       fix uninitialised arrays in USE_ORIGINAL_SBI version of seaice_solve4temp.F
4445    o pkg/seaice:
4446       new S/R seaice_solve4temp.F: this is the merged version of Ian Fenty
4447       code (seaice_budget_ice_if.F) which enable to recover old standard
4448       code (seaice_budget_ice.F) when option USE_ORIGINAL_SBI is defined.
4449       temporary: add "#define USE_ORIGINAL_SBI" at the top of seaice_solve4temp.F.
4450    o model/src (rStar):
4451       use simple average (not area weighted) of rStarFac at U,V point when using
4452       vectorInvariant and selectKEscheme=1,3 (consistent with mom. vertical advection)
4453       update output of exp. fizhi-cs-32x32x40 and fizhi-cs-aqualev20.
4454    
4455    checkpoint62k (2010/09/17)
4456    o adjoint
4457       * changed verification/global_ocean.cs32x15 ; adjoint now tests
4458         Adams-Bashforth 3 + NLFS + RSTAR
4459       * some more modifs required for ECCO-GODAE v4
4460    o pkg/seaice
4461       add SEAICE_AGE_VOL option to use volume instead of area for
4462       integrating SEAICE_AGE
4463    o model/src:
4464       first check-in of sigma & hybrid-sigma coordinate code ; also includes
4465       non-linear free-surface parts ; but pressure-gradient not yet coded.
4466    o pkg/ptracers:
4467       option for ptracer to convert Salt Relax into additional EmP.
4468        tested in exp. global_ocean.90x40x15.dwnslp (update output)
4469    
4470    checkpoint62j (2010/08/25)
4471    o pkg/ggl90:
4472       other minor changes: remove 3-D temp array gTKE (+ add argument myIter)
4473    o pkg/dic: car_flux.F, phos_flux.F
4474      - reduce number of exp-calls in order to improve performance
4475      - clean up a little (replace fields by their macros, etc., fix
4476        typo in CPP-flag)
4477    o pkg/ggl90: minor changes
4478      - GGL90diffKrS was removed --> always use GGL90diffKr
4479      - GGL90viscAr was removed --> replaced with GGL90viscArU, GGL90viscArV
4480      - hack of mxlMaxFlag=2 --> ensure mixing between first and second level
4481        (commented out for now)
4482      - change in max/min operations to ensure that smoothing is ok
4483      - smoothing of GGL90viscAr was moved to ggl90_calc.F (as done for GGL90diffKr)
4484      - always use diffKrNrT as background profile (i.e. never use diffKr field)
4485    o pkg/cfc: bug fix, AREA(i,j,1,bi,bj) -> AREA(i,j,bi,bj)
4486    o pkg/dic:
4487      - model/src/impldiff.F: if TARGET_NEC_SX, extend loop ranges for better
4488        vectorization
4489      - small bug fix in insol for the unlikely case of a cartesian grid
4490      - towards vectorizing the dic package: bio_export.F, car_flux.F, phos_flux.F
4491        + now vectorize, which also removes adjoint recomputations;
4492        + replace integer maksp1 by _RL maskp1
4493        + replace a**x by exp(x*log(a)) in phos_flux.F for speed
4494    
4495    checkpoint62i (2010/07/21)
4496    o pkg/flt:
4497      - with OBCS: stop floats which enter the OB region
4498    o model/src:
4499      - use tempVertAdvScheme & saltVertAdvScheme (instead of horizontal ones)
4500        for implicit vertical advection.
4501    o pkg/seaice:
4502     - account for melting in seaice age evolution.
4503     - remove double counting of seaice ridging effect on seaice age.
4504    
4505    checkpoint62h (2010/06/18)
4506    o pkg/exch2:
4507     - remove exch2_*xy_rx files: call was replaced with exch2_*3d_rx(myNz=1).
4508    o tools/genmake2
4509      - remove "-pdefault" option: redundant with the use of "packages.conf";
4510      - remove file pkg/pkg_default : set the default as a pkg group
4511        ("default_pkg_list") defined in pkg/pkg_groups;
4512      - fix for case pkg/pkg_depend is missing (was hanging before);
4513      - add option "-pgroups" to specify a different pkg_groups than the default.
4514    o verification/adjustment.cs-32x32x1:
4515       add a "minimal" set-up test (code_min & input_min) which only compiles
4516       eesupp/src and the 2 pkgs (exch2 & debug) which don't need model/src & inc.
4517    o tools/genmake2
4518      - extend pkg_depend rules to model & eesupp (e.g., if model depend on [pkg]))
4519      - fix details of checking for mnc & profile pkg when NetCDF is unavailable.
4520    o pkg/exf: merge exf_bulk_largeyeager04 into exf_bulkformulae because these
4521      files are nearly the same anyway.
4522      Step 1: make exf_bulkformulae look like exf_bulk_largeyeager04:
4523       - redefinition of tau(i,i) (by a factor of ustar)
4524       - 1./exf(Const/T) -> exf(-Const/T) (big change in the results)
4525       - replace rhonil by rhoConstFresh in computation of evap (bug fix)
4526       - replace u/vstress=tau*rd*ws*cw by tau*rd*u/vwind (changes results)
4527       - replace
4528         rd(i,j)= rdn(i,j)/(exf_one - rdn(i,j)/karman*psimh )
4529         shn    = sh(i,j,bi,bj)*rd(i,j)/rdn(i,j)
4530         by
4531         shn    = sh(i,j,bi,bj)/(exf_one - rdn(i,j)/karman*psimh )
4532         (changes results)
4533       -> exf_bulkformulae v1.22,
4534          update verification experiments lab_sea, offline_exf_seaice, seaice_obcs
4535          (lab_sea: output.hb87.txt 1.11, output.lsr.txt 1.25, output.salt_plume.txt 1.13,
4536                    output.txt 1.63
4537           offline_exf_seaice: output.seaicetd.txt 1.7
4538           seaice_obcs: output.txt 1.10)
4539      Step 2: do the actual merge and remove exf_bulk_largeyeager04.F
4540       -> exf_bulkformulae v1.23,
4541          unfortunately requires updating lab_sea.salt_plume (6 matching digits),
4542          and global_ocean.cs32x15.icedyn (only 11 matching digits)
4543      Also update output_adm of exp. lab_sea (all 4) and offline_exf_seaice.
4544    o adjoint of exch-1:
4545     - pass high-level EXCH S/R through TAF (eesupp/src/exch_ad_diff.list)
4546       (note: was already like this when using EXCH-2) and remove flow dir
4547       and hand-written AD version of high-level EXCH S/R (pkg/autodiff);
4548     - provide flow-dir for low-level exch1 S/R (eesupp/src/exch1_ad.flow);
4549     - update pkg/exch2 diff list.
4550    
4551    checkpoint62g (2010/05/19)
4552    o eesupp/src (exch-1):
4553     - split exch_rx.F into Forward S/R (exch1_rx.F) and Adjoint S/R (exch1_rx_ad.F)
4554       and remove argument "simulationMode"; same thing for all exch_*rx_cube.F
4555       (renamed to exch1_*rx_cube.F).
4556     - change accordingly exch_*_rx.template and AD version in pkg/autodiff
4557       to call new exch1 S/R ; update Makefile and .cvsignore.
4558     - replace call to exch2_xy_rx S/R with exch2_*3d_rx(myNz=1) (will remove
4559       exch2_xy_rx later)
4560      Note: after updating your code, need to run "make clean" in eesupp/src
4561    o test experiment bottom_ctrl_5x5:
4562       new output_adm.txt with fewer grdchk & less monitor output.
4563    o model/src:
4564      remove the call to ini_cori in initialise_varia.F (just keep the usual one
4565       in initialise_fixed.F). More consistent with coriolis & horizontal grid
4566       beeing treated in the same way (ini_grid is not called a 2nd time).
4567    o pkg/exf:
4568      - rewrite exf_bulk_largeyeager04.F for better vectorization, changes
4569      global_ocean.cs32x15/input.icedyn (11 digits of agreement), updated
4570      - fix adjoint (used worked for ALLOW_ATM_WIND defined, works for this now)
4571      - cosmetic changes to exf_bulkformulae.F to make it look more like
4572        exf_bulk_largeyeager04.F
4573    o eesupp/src (exch-1):
4574      - Fix AD EXCH code for 2-D domain special cases (Nx=1 or Ny=1).
4575      - Separate buffer filling and MPI sending: allow EXCH-1 to work for local
4576        array (non-shared) when using MPI+MTH. Also reduces number of BARRIER
4577        (even without using MPI).
4578      - Message mode: move RecvAck setting (indicator of buffer being ready)
4579        from send_put to recv_get S/R (was useless before, but not sure if
4580        it's much more useful now);
4581      - Switch the order of sync: MPI-proc 1rst and then threads;
4582      - take out spin-waiting code (#undef EXCH_USE_SPINNING), use BARRIER instead.
4583      - fix AD code for communication mode ='get' (but not used).
4584    o model/src:
4585      initialise dPhiHydX,dPhiHydY inside calc_grad_phi_hyd.F (so that TAF does
4586      not drop it in S/R mddynamics, producing NaN in hs94.1x64x5 AD-test exp).
4587    o utils/matlab/rdmnc.m: adapt to be able to use the generic matlab netcdf API
4588    o pkg/ctrl: require a specific set of control variables and exf-flags for
4589      adjoint of seaice (stop in ctrl_check.F if conditions are not satisfied)
4590    o model/src:
4591     a) 1rst version of a new driver S/R to turn-off output freq and flags after the
4592       1rst forward sweep, to avoid over-writing output files during recomputations
4593       recomputations (& grdchk); called from cost_final.F (& ctrl_init_ctrlvar.F ?)
4594     b) 2nd version:
4595      - add specific pkg S/R for seaice & ptracers (called from S/R TURNOFF_MODEL_IO);
4596      - switch-off more output flags (exf_monFreq, chkPtFreq, dumpInitAndLast,
4597         writePickupAtEnd) + seaice & ptracers output;
4598      - do not switch off MNC flags (otherwise, won't get admonitor netcdf file)
4599    o model/src:
4600      - new S/R rotate_uv2en_rl (..._rs) that rotates vector fields.
4601    o pkg/exch2:
4602      - remove "simulationMode" from arg. list of S/R EXCH2_RX1,2_CUBE ;
4603      - add argument "signOption" to EXCH2_RX1_CUBE (will be needed for SM exch).
4604    o pkg/autodiff & exch2:
4605      process exch_uv_agrid_3d_rx.f & exch2_uv_agrid_3d_rx.f through TAF
4606      (for now, only if ALLOW_EXCH2 is defined).
4607    o pkg/autodiff:
4608      - include PACKAGES_CONFIG.h in exch*ad.flow & exch*ad.F
4609        (not supposed to be in CPP_OPTIONS.h) to get ALLOW_EXCH2 defined correctly.
4610       + clean-up comments (_RS is not always real*4)
4611      - fix bug in ADEXCH_UV_3D_RX (without EXCH2, was calling the forward exch S/R)
4612      - add a stop in ADEXCH_UV_AGRID_3D_RX if trying to use it with EXCH2:
4613        was calling a forward exch2, which is wrong ; used in SEAICE & EXF pkgs.
4614    o testreport (AD-tests):
4615      no longer link files from dir "../input" (1rst link files from
4616      "../input_ad.[xx]" if secondary test "xx" and then from "../input_ad")
4617    
4618    checkpoint62f (2010/04/29)
4619    o model/src/the_main_loop.F:
4620      adjust store directives for seaice evp and multicategory according to
4621      pkg/ecco/the_main_loop.F
4622    o adjoint:
4623      global_sum_ad was incomplete (noted many times by many people ;)
4624      nice description by Jean U. as follows:
4625      * allreduce(var) in global_sum.F can be interpreted as
4626        reduce(sum) followed by broadcast of sum.
4627      * The adjoint of that is
4628        sum(adjoint) followed by broadcast(summed adjoint value)
4629        or in other words, allreduce(sum, adjoint vars)
4630      We were missing the sum(adjoint)!
4631      Benign, except(!) for "global" scalars appearing in tile loops (bi,bj)
4632      (noted by J.M. Campin, e.g., in cost_ssh_mean, variable offset).
4633      The fix should produce 16-digit accuracy between
4634      single-CPU multi-tile (e.g. nSx=2, nPx=1) and
4635      multi-CPU single-tile (e.g. nSx=1, nPx-2)
4636      We'll probably change this yet again shortly
4637    o eesupp/src:
4638      - fix global_sum_r4 (wrong from previous modif in Jun 2009; ever used ?)
4639    o pkg/icefront
4640      - ALLOW_SUBGLACIAL_RUNOFF option adds capability for time-evolving
4641        specification of addmass array based on a 2D field, which is added
4642        at bottommost wet level at each horizontal location.
4643    o model/src:
4644     horizontal grid initialisation (other than curvilinear): add code for Exch2 IO
4645     layout; (not always compatible with delX,delY setting; commented out for now).
4646    o pkg/exch2:
4647     change tile to processor setting (case nSy*nPy > 1): allows default model mapping
4648     (myX and myYGlobalLow) to be used for simple (1 facet, no blank tile) config.
4649    
4650    checkpoint62e (2010/04/15)
4651    o pkg/obcs:
4652      - fix wrong index in OBCS_SPONGE_V for Eastern-OB (reported by David Hebert).
4653    o pkg/dic:
4654      -fix bug in fe_chem.F for multi-tile (nSx*nSy > 1) set-up;
4655        (note: not presently tested in any forward verification exp.)
4656       update tutorial_global_oce_biogeo AD output file.
4657    o pkg/exf:
4658      - account for the variation of albedo as a function of zenith angle
4659        by defining ALLOW_ZENITHANGLE in EXF_OPTIONS.h
4660    o build_options:
4661     - rename "linux_ia64_ifort+mpi_ice_nas" to "linux_amd64_ifort+mpi_ice_nas"
4662    o pkg/dic:
4663      change DIC atmos-CO2 box (method 3, dic_int1=3) initialisation & restart:
4664      - use binary pickup file for restart;
4665      - initialise atmos-CO2 box from dic_pCO2 parameter;
4666      - fix multi-threaded.
4667    o pkg/rbcs:
4668     - clean-up RBCS code: add RBCS_OPTIONS.h file ; fix multi-threaded ;
4669       change (+ fix IO calls) type of array RBC_mask from _RL to _RS.
4670     - add RBCS to exp4 passive tracer 01 (rbcs was previously untested)
4671       and update output.txt
4672    o pkg/kpp:
4673     - add diagnostics for KPP non-local flux of Temp, Salinity and pTracers;
4674     - change diagnostic of KPP non-local term: output average of KPPghat*KPPdiffKzS
4675       (= ratio of KPP non-local (salt) flux relative to surface-flux) when
4676       using pkg/timeave & pkg/diagnostics (diag 'KPPghatK' replaces 'KPPghat ');
4677     - change pkg/offline to read-in average KPPghat*KPPdiffKzS from file
4678       KPP_ghatKFile (instead of the average of KPPghat from file KPP_ghatFile).
4679    o pkg/offline:
4680      fix bug in S/R OFFLINE_FIELDS_LOAD regarding surfaceForcing conversion factor
4681      (bug was added in version 1.10 on 2007-08-23).
4682    o pkg/offline:
4683      - no need to specify periodicExternalForcing, etc ... to use offline pack
4684      - offline input files no longer just single prec --> parameter offlineLoadPrec
4685    o verification/lab_sea:
4686      change AD test to multi-tile setup and update all 4 AD output.
4687      NOTE: while cost function values remain very similar,
4688      gradients are very different, although gradient checks are self-consistent
4689      Should try to get to the bottom of this (cost function summation order?)
4690    o pkg/dic:
4691      in carbon_chem.F, replace log10 (AUTODIFF) with explicit form to avoid
4692      a weakness of TAF that drops part of double precision in log10 derivative.
4693      <= changes removed since problem has been fixed in current TAF version 1.9.71
4694      update AD output of exp. tutorial_dic_adjoffline & tutorial_global_oce_biogeo.
4695    o pkg/ecco:
4696      add missing "_d 0" in cost_readers.F, cost_readtopex.F & cost_readtopexmean.F
4697      update all 4 lab_sea AD output.
4698    
4699    checkpoint62d (2010/03/22)
4700    o build_options:
4701      remove '-r8' (and '-i4') from linux_*pgf and linux_*ifort optfiles.
4702    o remove unbalanced quote (single or double) in commented line of source code
4703      (may cause some warning with some preprocessor/makedepend versions).
4704    o pkg/seaice:
4705      fix seaice_model.F for adjoint (gael) and update AD results of experiments
4706       lab_sea (std + evp + noseaicedyn) and offline_exf_seaice.
4707    o testreport:
4708      add option '-runonly' (short: '-ro') to just do the run part (without make).
4709    o eesupp: remove JAM communication code (obsolete).
4710    o add option to genmake2 & testreport to switch "_RS" type to "real*4"
4711      (if allowed in CPP_EEOPTIONS.h); update default CPP_EEOPTIONS.h and return
4712      to default CPP_EEOPTIONS.h for exp. inverted_barometer & solid-body.cs-32x32x1
4713      (update also the output).
4714    
4715    checkpoint62c (2010/03/02)
4716    o tools/build_options :
4717       move (some) old optfiles from build_options/ to build_options/unsupported/
4718    o model/src and pkg/exf
4719       surface relaxation -- separating data and data.exf options
4720       The point is to ensure that we specify the surface relaxation
4721       either in data or in data.exf (but not half and half) and to
4722       avoid an accidental relaxation to 0 (which happened if a time
4723       scale was specified but the file name was left empty)
4724    o model/src model/inc and pkg/mom_common
4725       ALLOW_3D_VISCAH/ALLOW_3D_VISCA4 => 3D specification of Viscosity
4726       => addition to the viscosity field as computed by others schemes
4727    o tools/build_options:
4728      - rename "_generic_mpi" -> "+mpi_generic" (like other "+mpi" optfile)
4729        but keep the former optfile for few weeks for smooth transition
4730    o pkg/ecco
4731      - allow user defined cost function contributions
4732         CPP: ALLOW_USERCOST_CONTRIBUTION
4733         USAGE: compute contributions in cost_usercost_all.F
4734      - note: this is identical to what ALLOW_GENCOST_CONTRIBUTION once was.
4735          the two options are complementary.
4736    o pkg/smooth
4737      - migration from contrib to the main repository
4738    
4739    checkpoint62b (2010/01/26)
4740    o pkg/monitor:
4741      - change back mon_printstats_rl.F & mon_stats_rl.F and add a stop
4742        (in case someone forgot to update customized pieces of code)
4743    o nonHydrostatic:
4744      - add Non-hydrostatic free-surface form (selectNHfreeSurf=1)(not fully tested);
4745      - add a simple 2-D experiment (short_surf_wave) to test it.
4746    o pkg/icefront:
4747       adding the shell of, and the hooks to, a new package that
4748       will model melting and freezing of vertical glacier ice fronts
4749    o momentum:
4750      add diagnostics of momentum tendency from Hydrostatic pressure gradient
4751       (without surf.pressure term: would need a 2nd filling since implicit term).
4752    o add 3 "_d 0"s so that fizhi compiles with xlf on iblade, and replace
4753      two " &end" by " &" (in fizhi-cs-*) because S/R NML_SET_TERMINATOR
4754      cannot deal with the former
4755    o cleaning:
4756      - remove all (except OpenAD) old TLM output from results_ad dirs.
4757      - remove unused S/R (MDSWRITEMETA, DIAGNOSTICS_ADD2LIST, old DFILE IO S/R)
4758      - comment out maskH definition (replaced by maskInC)
4759    o pkg/monitor:
4760      - change mon_printstats_rl.F & mon_stats_rl.F (were similar to mon_writestats_rl
4761        & mon_calc_stats_rl) to be the RL equivalent of mon_printstats_rs & mon_stats_rs.
4762    
4763    checkpoint62a (2010/01/15)
4764    o model/src:
4765      - bottom pressure diagnostic: correct for r* (when nonlinFreeSurf >= 4)
4766    o pkg/diagnostics:
4767      - add optional level number diagnostics (i.e., level number to be define
4768        explictly with S/R DIAGNOSTICS_SETKLEV) with parser-code(10)="X".
4769      - strictly check for valid parser-code(10) ;
4770      - check if adding diag to the list from the right place.
4771    o pkg/longstep:
4772      - change parameters and fix tracer conservation with rstar/nonlinear free surface
4773    o diagnostics:
4774     - in all pkgs, replace remaining calls to old S/R DIAGNOSTICS_ADD2LIST with newer
4775       S/R DIAGNOSTICS_ADDTOLIST ; fix seaice VICE diagnostics.
4776    o pkg/diagnostics:
4777     - Add option for writing vertical integral (sum of selected levels) of an output
4778        field instead of writing output field levels. Activate this option on a per
4779        output-file basis, by setting the 2nd character of fileflag to 'I'.
4780     - Add field-specific information relative to level integral in 3rd postion
4781        of parser diagnostics code (gdiag): " "=cumulate levels, "R"=integrate
4782        vertically (x level-thickness x hFac), "r"=same but without hFac.
4783    o do_the_model_io:
4784      - pass end-of-model-run flag as argument, from forward_step to diagnostics_write:
4785        in case useSIGREG, will write (averaged) diagnostics (if dumpAtLast) before
4786        writing pickups and stopping.
4787    o pkg/diagnostics (for now, only with mdsio):
4788      - write time information to meta file (and modify accordingly rdmds.m) :
4789        time-averaged diagnostics output: write starting and ending time of the
4790        time-averaging interval ; snap-shot diagnostics output remains unchanged;
4791    o pkg/timeave:
4792      - S/R TIMEAVE_NORMALIZ: change size of cumulated-time array (was previously
4793        always Nr), now assumed to be equal to number of levels of averaged field;
4794        only used for DIC_COST monthly mean arrays: this fixes dic_aver_final.F
4795    o pkg/sbo:
4796      - fix ocean bottom pressure global-average & 2-D time-ave output (was
4797        neither initialised nor filled).
4798      - add starting iteration in suffix of global-average output file
4799        (to avoid over-writing the file after a restart)
4800      - use standard MDSIO pkg S/R instead of SBO_WRITEVECTOR (fix byte-swap Pb).
4801    o time-average:
4802      - use simple cumulative-time array (no k index) in all pkgs: {PKG}_timeAve(bi,bj)
4803        (pkgs: aim_v23, bulk_force, dic, gmredi, kpp, land, ocn_compon_interf,
4804         ggl90, my82, opps, pp81, ptracers, sbo, seaice, shelfice, thsice)
4805        this fix DIC_COST cumulative-time array (previously: bi,bj,k)
4806      - fix 1rst call (nIter0) snap-shot output and accumulation (pkg/shelfice)
4807      - fix missing accumulation for pkg/opps.
4808      - cumulate fields only if doing time-ave output ({PKG}_taveFreq > 0)
4809         (pkgs: ptracers, kpp, ocn_compon_interf, ggl90, my82, pp81);
4810      - fix initialisation of time-ave vars and do only full time-step increment
4811        (i.e.: no first & last "half time-step") (pkgs: ggl90, my82, opps, pp81);
4812    o pkg/layers:
4813      - use standard RW pkg S/R to write the output
4814        and remove local write_fld version (which had a problem).
4815      - use simple cumulative-time array (no level index) to fix time-ave S/R calls.
4816      - fix LAYERS_CALC argument list.
4817    o pkg/timeave:
4818      - store cumulative-time in a simple tiled array (drop the level index)
4819      - add new S/R (TIMEAVE_NORMALIZE) which uses simple cumulative-time array.
4820    o pkg/ocn,aim_compon_interf
4821      - changes for multi-threaded coupled run. (tested with ifort-11 on danton)
4822    
4823    checkpoint62  (2009/12/23)
4824    o switch on useOBCSbalance in tutorial_plume_on_slope exp. and update output.
4825        (was not previously tested in any other exp.)
4826    o pkg/monitor:
4827      - clean-up _RL/_RS version: add specific S/R for statistics with mask & volume:
4828        mon_writestats_rl/s,F mon_calc_stats_rl/s.F ; will keep the old one
4829        (mon_printstats_rl/s,F mon_stats_rl/s.F) just for bare statistics.
4830      - use hFac & 2-D mask (instead of 3-D mask + hFac in previous mon_stats_rl.F).
4831      - change del2 calculation.
4832      - use interior masks (instead of maskH, <- to be remove).
4833      - shorter monitor suffix for forcing stats ("forcing" instead of "extforcing").
4834    o mask & obcs:
4835      - define 2-D "interior" masks (i.e., zero beyond OB) at 3 locations (C, W & S).
4836      - move global area computation from ini_masks_etc.F to ini_linear_phisurf.F
4837        (called after packages_init_fixed)
4838    o pkg/obcs:
4839      - move bi,bj loops into obcs_calc, so obcs_prescribe_read is called only once.
4840        Fixes bug in obcs+exf with nSx*nSy.GT.1
4841      - fix multi-tile handling in obcs balance code
4842    o nonHydrostatic:
4843      - Implement AB-3 for non-hydrostatic vertical momentum ;
4844        (change ordering of var. stored in pickup file when using NH)
4845      - move NH code from solve_for_pressure.F to 2 new S/R: PRE_CG3D & POST_CG3D.
4846      - add 2-D field to store Hydrostatic Surface Pressure adjusment from cg3d_x
4847        (in prep. for new NH free surface form).
4848    o pkg/obcs:
4849      add files & OB-variables for wVel (Non-Hydrostatic) with useOBCSprescribe
4850    o model/src:
4851      fix 2-D solver initialisation for deep-atmosphere (p-coord) with topography
4852    
4853    checkpoint61z (2009/12/01)
4854    o nonHydrostatic:
4855      Fix missing vertical flux of vert. momentum near surface (k=1). This fixes
4856        a spurious source of energy in simple baroclinic adjusment test case.
4857      Update all non-hydrostatic exp output.
4858    o model/src (3-d solver):
4859      Change again 3-D solver free-surface RHS term when exactConserv=T:
4860        simpler, consistent with exactConserv, and works with implicDiv2Dflow < 1
4861        (which was not the case with previous formulation).
4862      To recover previous version, just reset "oldFreeSurfTerm" to previous value.
4863      Affects results of exp. global_ocean.cs32x15.viscA4 & hs94.cs-32x32x5.impIGW.
4864    o nonHydrostatic:
4865      - compatible with implicDiv2Dflow < 1 ; + implement implicit factor
4866        for Non-Hydrostatic pressure gradient (similar to implicSurfPress).
4867      - change 3-D solver to work with r* (for now, only with linear free-surf.)
4868      - add few debug diagnostics (cg3d_x, residual)
4869    o model/src:
4870      fix missing EmPmR in 3-D solver RHS (was in cg2d_b but missing in cg3d_b).
4871        update output of exp. global_ocean.cs32x15.viscA4
4872    o update output of exp. global_ocean.cs32x15.icedyn after removing
4873      #define SEAICE_OLD_AND_BAD_DISCRETIZATION from SEAICE_OPTIONS.h
4874    o add entry points for Gianmaria's Nesting pkgs (from Contrib/nesting_sannino)
4875    o mnc: add horizontal grid coordinates (XC,YC) and (XG,YG) to netcdf output
4876      for complex grids, for now only to "state", "adstate", "adexf", "adseaice"
4877    o model: add Christopher Wolfe's implemetation of the single reduction cg2d
4878      (d'Azevedo, Eijkhout, and Romine, 1999) with CPP-flag ALLOW_SRCG and
4879      runtime flag useSRCGSolver. Modify verification experiment global_with_exf
4880      to test this code
4881    o pkg/cd_code:
4882      Change defaut D-grid time-stepping to get the same for D-grid momentum as for
4883       C-grid momentum. D-grid velocity used to be stepped forward in time with
4884       Adams-Bashforth only on surface pressure term. Tests show that using AB on
4885       D-grid coriolis term improves stability (as expected from CD-scheme paper).
4886      To reproduce old results, add 2 options (in CD_CODE_OPTIONS.h).
4887      Update results of exp: global_with_exf (x2), ideal_2D_oce, isomip (x2),
4888       lab_sea (3 Fwd +3 AD), natl_box (x2), tutorial_global_oce_biogeo (Fwd+AD),
4889       tutorial_global_oce_latlon, tutorial_global_oce_optim & tutorial_tracer_adjsens.
4890      Keep old results by adding CD_CODE_OPTIONS.h in exp: cfc_example, exp2,
4891           global_ocean.90x40x15(+AD), global_ocean_ebm(+AD) and OpenAD.
4892    o pkg/obcs:
4893     - fix bug in initialisation (broken since Oct 1rst modification)
4894       for useOBCSprescribe without useEXF.
4895    
4896    checkpoint61y (2009/11/15)
4897    o pkg/seaice
4898     - change (once again) the discretization for the evp solver: rather than
4899       squaring the averages of strain rates, average the squares to give
4900       a better approximation to VP behavior (in simple test); this breaks
4901       verification experiments that use EVP (lab_sea and lab_sea.hb87)
4902        --> update outputs
4903    o add CPP-flag (in mom_calc_visc.F) and TAF directive (in gmredi_slope_limit)
4904      to improve vectorization of adjoint code on TARGET_NEC_SX
4905    o verification/vermix:
4906      - change vermix to a more "classical" 1d column with high vertical
4907        resolution, seasonal heat flux forcing and constant wind forcing
4908        --> update outputs
4909    o pkg/seaice
4910     - fix diagnostics of principal stress components for EVP
4911     - add optional diagnostics of non-linear convergence for LSOR solver
4912     - make maximum zeta a runtime parameter
4913    o model/src (3-d solver):
4914      Undo modif from Dec 12, 2005 (solve_for_pressure.F cvs version v.49),
4915       which consisted in removing the Surf. Non-Hydrostatic pressure from the
4916       whole column and adding it to Eta (inspired from Casualli, 1999):
4917       Only affects 3-D solver initial guess and only if using ExactConserv,
4918       but tests did show a degradation of solver convergence. For this reason,
4919       decide to disable this piece of code.
4920       to recover previous version, just set zeroPsNH = exactConserv (line 78).
4921      Update output of exp. global_ocean.cs32x15.viscA4 & hs94.cs-32x32x5.impIGW
4922    o pkg/ggl90:
4923     - fix previous modif (unfortunatly has not been documented here).
4924    o pkg/seaice/autodiff:
4925     - add CPP flag to include clipping of zeta in EVP code;
4926       although clipping of zeta is not necessary for EVP and not recommended
4927       it was done by default, now clipping is disabled by default
4928     - modify computation and store zetaC/Z in seaice_evp for TAF
4929     - add CPP-flag SEAICE_ALLOW_CLIPVELS (undefined by default)
4930     - change seaice_calc_viscosities/strainrates for better
4931       vectorization after AD by TAF
4932     - rearrange common blocks in SEAICE.h once again for easier dumps of
4933       adjoint output, adjust adcommon.h and g_common.h
4934     - change flux form of default advection scheme for better vectorization
4935       of adjoint code
4936     - modify lab_sea/input.lsr to test the flux form of default advection
4937       scheme
4938    o autodiff: fix seaice fields in g_common.h (left over from 3 to 1 level
4939      transition in checkpoint61r)
4940    
4941    checkpoint61x (2009/10/19)
4942    o adjoint: adding two new verification experiments
4943      * tutorial_global_biogeo: an online dic sensitivity experiment
4944        (work with G. Forget)
4945      * tutorial_dic_adjoffline: an offline dic sensitivity experiment
4946        (an update of the Dutkiewicz et al., 2006 paper)
4947      Both use the same CO2FLUX cost function, but different controls
4948      Gradient checks look good, but some recomp. could still be traightened out
4949      Should add xx_dic control variable to test at some point
4950    o model/src:
4951      add run-time parameters to check and/or mask initial Temp & Salt
4952    o pkg/ptracers:
4953      apply zonal filter (if used) to all passive tracers
4954    
4955    checkpoint61w (2009/10/12)
4956    o adjoint:
4957      * update and finish work on adjoint of dic package (G. Forget)
4958      * start adjoint of offline package
4959      * bug fix for cube-sphere TLM code (active_file_g.F)
4960    o tutorial_global_oce_optim:
4961      now tested with 4 tiles (change data.grdchk and update output_adm.txt)
4962      and add SIZE.h_mpi for MPI testing
4963    o pkg autodiff
4964     - fix bug in autodiff_restore
4965     - make genmake2 remove comments and empty lines from ad_input_code.f in
4966       order to reduce file size (new script file remove_comments_sed)
4967    o allows to specify vertical profile of vertical viscosity (viscArNr)
4968    o pkg autodiff
4969      autodiff_ini_model_io: comment out writing of grid information to netcdf
4970      files, because at this time the grid fields are a bunch of zeros
4971      (this is analogous to ini_mnc_vars.F)
4972    o pkg seaice/autodiff:
4973     left-over from removing the 3-time-level fields:
4974     - small rearrangement of common blocks (SEAICE.h)
4975     - fix field declaration in order to get meaningful output in
4976       adseaice.*.nc (adcommon.h)
4977    o pkg obcs:
4978     - go through NH code only if nonHydrostatic=T
4979     - fix restart for Orlanski (Hydrostatic; still to fix NH+Orlanski restart)
4980     - move call to OBCS_CALC before SEAICE_MODEL which needs seaice-obc fields
4981       => Update output of experiment seaice_obcs
4982     - useOBCSbalance: code is wrong with multi-tile / proc: add a stop.
4983     - fix NH+Orlanski restart (add wvel OBC value in pickup file)
4984     - fix restart for useOBCSprescribe + useEXF
4985    o pkg ctrl
4986     - make obcs as control parameter work also with useSingleCPUio
4987     - replace a few sny and snx by Ny and Nx to be consistent with
4988       ctrl_set_globfld_x/yz.F
4989    o pkg seaice
4990     - re-introduce global field frWtrAtm for the case of
4991       ALLOW_MEAN_SFLUX_COST_CONTRIBUTION defined (SEAICE.h, seaice_growth.F)
4992     - catch the case of an empty filename in seaice_cost_init_fixed.F
4993    o pkg ecco:
4994     - small bug fixes in the_main_loop
4995      . fix order of monitor arguments
4996      . change SEAICE_MULTILEVEL to SEAICE_MULTICATEGORY
4997      . move include DYNVARS.h up outside the ALLOW_AUTODIFF_TAMC block so
4998        that ALLOW_ECCO_FORWARD_RUN works with NONLIN_FRSURF
4999     - replace cos(yc*deg2rad) by _rA in cost_mean_heat/saltflux.F, fix the
5000       imbalance diagnostics for wmean_h/sflux = 0
5001     - add actual values to f_obcsn/s/w/e in ecco_cost_final.F
5002     - catch the case of empty filenames in ecco_cost_init_fixed.F
5003       and ecco_readparms.F
5004     - fix the logic of wsalt=0.and.wsalt2=0 to wsalt=0.or.wsalt2=0 (and theta)
5005       to make this statement meaningfull in ecco_cost_weights.F
5006    o pkg zonal_filt:
5007      - change ZONAL_FILTER S/R interface (allows to filter 2-D fields)
5008      - when using rStar, filter uVel*hFacW instead of uVel
5009       (tested without topography: fix a Pb of growing instability with NLFS)
5010    o pkg/aim/thsice:
5011     -Add capacity to read a Q-Flux to be applied in slab-mixed layer thsice_slab_ocean.F
5012      (works as SST restoring)
5013    o pkg/thsice:
5014     -add specific parameter for salt restoring in slab mixed-layer
5015       (by default equal to the temperature restoring)
5016    
5017    checkpoint61v (2009/09/21)
5018    o pkg/kpp:
5019     -add double diffusive contributions as a hack, turned off by default
5020      for now, and the code can be excluded with a CPP-flag
5021      EXCLUDE_KPP_DOUBLEDIFF just as EXCLUDE_KPP_SHEAR_MIX
5022     -add a verification experiments to "vermix" to test this code
5023    o pkg/mom_common:
5024      Move computation of length scales to mom_init_fixed.F (avoid recomputation
5025      at each time-steps*levels).
5026    o pkg/layers:
5027      Created a new package for computing volume fluxes in temperature or
5028      [not yet implemented] density layers, e.g. for calculating residual
5029      overturning circulations.
5030    o pkg/diagnostics:
5031      implement a RS type version for the set of DIAGNOSTICS-FILL subroutines
5032    o fix few RS/RL type mismatch (check with ifort 11.1 "-warn all" option)
5033    o pkg/mdsio (& pkg/rw): rework high level S/R interface:
5034      To avoid mixing type (RS/RL) of input/output array argument,
5035      replace single mixed-type array with a pair from each type (RS/RL).
5036    o setting pickupSuff force to start from a pickup (even if nIter0=0): this
5037      is now implemented for all pkgs (previously only done for the main pickup)
5038    
5039    checkpoint61u (2009/08/25)
5040    o pkg/obcs:
5041      - change OB?eta from _RS to _RL and put them into a separate commen block
5042      - add code to read OB?eta from a file via obcs_prescribe_read: the code
5043        compiles and does not destroy any other experiments, the data is read
5044        properly, but the code is not tested in actual applications
5045    o ini_mnc_vars.F: if available (ALLOW_CAL), use startTime_1 and 2 to
5046      create a meaningful unit attribute for the time coordinate variable
5047    o pkg/ebm: add plenty of missing "_d 0" ;
5048       update results of experiment global_ocean_ebm (fwd + adjoint tests)
5049      Notes: several pieces of code only works for (very) specific set up
5050       (domain size, lat range, etc ...); should be documented & stop if one
5051       of those assumptions is not meet.
5052    o pkg/seaice: add missing "_d 0" in HSNOW initialisation
5053       update results of experiments: lab_sea (3 fwd tests + 2 adjoint tests)
5054          and offline_exf_seaice (seaicetd + adjoint).
5055    o add missing "_d 0" in ShortWave flux penetration (S/R SWFRAC):
5056       update results of experiments: lab_sea (4 fwd tests + 3 adjoint),
5057        seaice_obcs, global_ocean.cs32x15 (icedyn & thsice) and natl_box (x2).
5058    o few changes to pass when compiling with strick checking of arguments
5059       across S/R (allow to find few bugs in S/R calls).
5060    o pkg/seaice:
5061     - seaice_evp: move if-statement out of loop (TEM) at the cost of 11 new
5062       2d-fields, for slightly better performance
5063    
5064    checkpoint61t (2009/07/22)
5065    o pkg/seaice:
5066     - remove unused variables in seaice_evp
5067     - reduce number of SQRT in seaice_evp and seaice_calc_viscosities
5068    o eeset_parms.F, open_copy_data_file.F & ini_parms.F:
5069       named file replacing SCRATCH files (for TARGET_BGL & TARGET_CRAYXT):
5070       each processor opens a different file (a fix from Matt).
5071    o cg2d:
5072       use simple EXCH (overlap size = 1 and ignore corners), like in cg3d.F :
5073       this reduces number of EXCH calls by 2 when using exch2.
5074       For now, keep previous size array for gc2d_nsa.F to avoid Pb with store
5075       directives and missing simple EXCH (exch_s3d_rx) adjoint code.
5076    o pkg/thsice:
5077       add code for Near Infra-Red albedo (from Jeff)
5078       (turned on with run-time flag: thSIce_calc_albNIR, in data.ice).
5079    o ini_model_io:
5080       move (from packages_readparms.F & initialise_fixed.F) to ini_model_io.F
5081       MNC & MONITOR initialisation calls; move MNC calls from {pkg}_readparms.F
5082       to {pkg}_init_fixed.F for {pkg}= kpp, seaice & shelfice.
5083    
5084    checkpoint61s (2009/06/30)
5085    o pkg/exch2 (exch2_rxN_cube*):
5086       remove last BARRIER (no need to synchronise after getting data from shared
5087       buffer (get) as long as any change to buffer (put,recv) is between BARRIER)
5088    o change tiling of natl_box (from 2 to 4 tiles) to get it tested with MPI+MTH
5089      and generate new output (for the 2 tests) using default rotationPeriod.
5090    o pkg/exch2:
5091      - always call exch2_*_cube, not exch-1 anymore, if useCubedSphereExchange=F
5092        (was already the case with AUTODIFF_EXCH2 defined)
5093      - add bj in exch2 arrays and S/R.
5094      - can now use pkg/exch2 for regular (non CS) set-up; switch test experiment
5095        MLAdjust to exch2 (identical results except with MPI -> truncation diff);
5096    o add pkg/longstep for ptracer timestep a multiple of U/V/T/S timestep
5097      - adds deltaT argument to the subroutines TIMESTEP_TRACER DWNSLP_APPLY
5098        GAD_ADVECTION GAD_CALC_RHS GAD_IMPLICIT_R GAD_SOM_ADVECT
5099      - verification experiment natl_box.longstep
5100    o build_options: ifort+mpi_aces optfile (following Constantinos advise):
5101      allow different versions of ifort (8 or 9) and different versions
5102       of mpi (mpich or mpich2) to be used with the same optfile.
5103      requires to load a netcdf module and set MPI_INC_DIR (see comments inside
5104       optfile). Change testing scripts (example_scripts/ACESgrid) accordingly.
5105    o pkg/seaice:
5106      fix previous modif (3-level field removed) for old-pickup reading
5107    
5108    checkpoint61r (2009/06/25)
5109    o pkg/seaice:
5110     - clean up the 3-time levels of UICE,VICE,HEFF,AREA in three steps:
5111      1. introduce fields for time step (N-1)
5112      2. do not use levels 2 and 3 anymore (but keep them)
5113      3. replace 3D versions of UICE,VICE,HEFF,AREA by 2D versions. This
5114         includes changes to pkg/thsice/thsice_get_velocity.F,
5115         model/src/external_forcing_surf.F, pkg/obcs/obcs_apply_seaice.F, and
5116         pkg/obcs/obcs_apply_uvice.F.
5117     - completely remove code for leap-frog time stepping for second order
5118       advection
5119     - adjusted adjoint accordingly;
5120       gradient checks have improved by an order of magnitude!
5121    
5122    checkpoint61q (2009/06/22)
5123    o pkg/seaice: fix bug in free slip boundary conditons for LSOR solver
5124     - the boundary conditions along open boundaries are unclear, because the
5125       associated masks are set to zero and are thus treated as closed when
5126       applying the slip-boundary conditions.
5127     - move initialisation of grid variables from seaice_init_varia to _fixed
5128    o adding doc/diags_changes.txt
5129    o model/src:
5130      do_the_model_io: rename few pkg S/R which are called from do_the_model_io,
5131       to avoid "_diags" naming if no relation to pkg/diagnostics.
5132      ini_theta,ini_salt: fix (at least compile the code) reading from NetCDF
5133       file and only call PLOT_FIELD_XYZ if debugMode=T.
5134      remove few PLOT_FIELD_XY calls outside initialisation.
5135      remove few unnecessary BARRIER.
5136    o pkg/salt_plume: add SaltPlumeSouthernOcean to allow disabling
5137      of salt_plume package in Southern Ocean
5138    o pkg/thsice:
5139     - fix hOceMxL in overlap (needed for sea-ice advection);
5140       update output of experiment global_ocean.cs32x15.icedyn.
5141    o pkg/seaice:
5142     - make the (placeholder-)tracer IceAge a little more meaningful
5143      by avoiding ridging of age due to convergent ice flow
5144     - add diagnostics for surface temperature, atmospheric and oceanic
5145       heat flux, and atmospheric and oceanic ice growth
5146    
5147    checkpoint61p (2009/06/10)
5148    o eesupp (global_max & global_sum):
5149     - add one more element to buffer (start at index 0) for GL_MAX/SUM output;
5150     - remove starting & endding barrier (no longer needed)
5151    o pkg/mdsio, writelocal:
5152       works also in multi-threaded when LOCBIN_IO_THREAD_SAFE is undefined
5153       (remove the STOP): uses shared buffer IO to store data from all threads
5154       and then let master-thread write nThreads tiles.
5155    o pkg/mdsio (read/write field):
5156     - tiled IO done in 1 piece (all levels at a time);
5157     - new header file "MDSIO_BUFF_3D.h" with 3-D buffers.
5158     - multi-threaded: allow to read/write local (non-shared) array
5159       (was already working with singleCpuIO ; now works also without);
5160       => no longer needs barrier call after reading a file (added inside
5161       mds_read/write field).
5162     - move barrier calls outside gather/scatter_2d to mds_read/write_field
5163    o pkg/obcs/exf
5164      - exf_getffieldrec.F: add a few ". _d 0" and
5165                            add code to catch the case fldperiod = 0.  
5166      - obcs_precribe_read.F: change if statements so that they match
5167                              the variable type (_RL)
5168      - add a separate exf_iprec_obcs to exf_set_obcs (by default equal to
5169        exf_iprec) as part of namelist EXF_NML_01
5170    o pkg/mdsio:
5171      - read/write tiled (local) files: read/write 1-level tile chunk at a time
5172        (instead of segment of length sNx); expected to speed up tiled IO.
5173    o pkg/exch2:
5174      - take buffer copy from/to array out of S/R exch2_send/recv into new
5175        S/R exch2_put/get ; Exch of local variable now works with MPI+MTH
5176        (tested by removing commom block statement in SOLVE_FOR_PRESSURE.h).
5177      - ad version of send/recv no longer needed (but needs exch2_ad_put/ad_get)
5178      - simplify argument list of S/R exch2_get_uv_bounds and exch2_get_scal_bounds
5179        (which replaces exch2_get_recv_bounds & exch2_get_send_bounds) by
5180        including Topology header file (and common blocks).
5181      - implement EXCH_IGNORE_CORNERS in scalar exchange (rx1);
5182        remove 2nd exch call in exch2_s3d_rx (no longer needed).
5183      - document S/R arg. list (+ update some comments)
5184    o pkg/seaice:
5185      - added SEAICE_CLIM_AIR code, which permits modulation of surface air
5186        temperature and humidity over sea ice based on climatological values.
5187      - clean up computation of Hibler+Bryan (1987) stress coupling for the case
5188        of LSR (this change is expected to change the results slightly because now
5189        it uses slightly difference moduli from the second last LSR solution, but
5190        that is more consistent with the stress computations; this part of the code
5191        is not tested in the verification experiments)
5192      - fix diagnostics for flux of ice in case of B-grid
5193      - turn strain rates eij and press into global fields within global
5194        common block in SEAICE.h for more straighforward diagnostics
5195      - fix diagnostics for principal stress components, press, zeta, eta
5196        to give something meaning full
5197    o change tiling of global_ocean.cs32x15 (12 tiles, 32x16) and generate
5198      new output (all 4 tests) using default rotationPeriod.
5199    o pkg KPP:
5200      - add flag (LimitHblStable) to avoid limiting BL depth under stable conditions
5201      - fix vertical indices in RI_IWMIX (match between KPP grid from 0 to Nr+1
5202        and normal grid from 1 to Nr)
5203    o Fix computations of L4rdt in mom_calc_visc.F
5204    o eesupp:
5205      new S/R ALL_PROC_DIE (like EEDIE, without irrelevant threads err msg):
5206      should be called before a "stop" if we know that all process are going
5207      to stop; if one Proc does call this S/R, will hang in MPI_FINALISE.
5208    
5209    checkpoint61o (2009/05/26)
5210    o pkg/exch2: change check_depths to issue just a warning (instead of error+stop)
5211    o model/src/ini_curvilinear_grid.F:
5212       compute angleSin/CosC when they are not read from a file
5213    o pkg/seaice:
5214       add pseudo time stepping for LSOR
5215    o pkg/exch2:
5216       temporary fix for exch2_s3d_rx; update results of exp. hs94.cs-32x32x5.impIGW
5217    o pkg/seaice:
5218       Adding separate sea ice albedo, drag coefficients, and HO in Southern
5219       Ocean from those in Arctic Ocean.  See *_south in SEAICE_PARAMS.h
5220    o SingleCpuIO:
5221       fix bug put before chkp61n (May 11), when more than 2 MPI cpu are used.
5222    o pkg/seaice:
5223       put exchanged variable in (local) common block for MPI+Multi-Threads
5224       to work (necessary with exch1, and for now with exch2 too).
5225    o verification: to get more experiments tested with mpi, mth and mpi+mth,
5226      change tiling of:
5227       aim.5l_Equatorial_Channel, aim.5l_LatLon, dome, exp4, global_ocean.90x40x15,
5228       hs94.cs-32x32x5, MLAdjust, offline_exf_seaice & tutorial_plume_on_slope
5229      update output of exp:
5230       exp4, global_ocean.90x40x15(+.dwslp), MLAdjust(all 5),
5231       tutorial_plume_on_slope and hs94.cs-32x32x5 (use default rotationPeriod)
5232      + ideal_2D_ocean: use default rotation period + test Global_Sum_SINGLECPU
5233                       (note: output.txt generated on faulks using only 1 tile)
5234    o eesupp & mdsio (SingleCpuIO):
5235     - remove MISSING_TILE_IO (from MDSIO_OPTIONS.h), replaced by run-time
5236       parameter "W2_useE2ioLayOut" (read from file "data.exch2").
5237       Note: was not effective for globalFile & useSingleCpuIO=F; now fixed.
5238     - move MDSIO_SCPU.h (pkg/mdsio) to EEBUFF_SCPU.h (eesupp/inc).
5239     - fix GLOBAL_SUM_SINGLECPU when using Exch2; re-use same buffers and same
5240       gather/scatter S/R as with SingleCpuIO (=> 1 less 2D global RL array).
5241    o pkg/exch2:
5242     - new code to set-up W2-Exch2 topology (replace matlab-topology-generator):
5243       read parameter file "data.exch2" if it exists; otherwise try default regular
5244       cube without blank-tile; new header file "W2_EXCH2_SIZE.h";
5245     - update matlab-topology-generator (exch2_setup_cs6_print.m) to be compatible
5246       with new code (not to be used, just as a backup solution).
5247     - add examples (e.g., for lat-lon-cap_120) of parameter file "data.exch2"
5248       in utils/exch2/input.
5249    
5250    checkpoint61n (2009/05/12)
5251    o eesupp & mdsio (SingleCpuIO):
5252      - move mapping to global io-buffer inside gather_2d/scater_2d: this save
5253        memory (1 less 2D global RL array); skip 1 buffer copy; and only send/
5254        receive real*4 array (instead of real*8) to read/write 32.bit files.
5255        (new template for gather_2d/scater_2d, new set of S/R MDS_PASS_R4,8toRL,S
5256         and remove new mapping S/R)
5257    o pkg/mdsio: in preparation for topology-generator within pkg/exch2:
5258      - Change declaration of SingleCpuIO buffer, reduced to only 1 dim.:
5259        xyBuffer_size, which is set to W2_ioBufferSize from W2_EXCH2_PARAMS.h
5260        when using exch2. Add S/R to map global io-buffer to global model array.
5261      - uses exch2_global_Nx,y instead of exch2_domain_nxt,nyt.
5262    
5263    checkpoint61m (2009/04/29)
5264    o write_utils : change WRITE_1D_R8 to WRITE_1D_RL
5265      and add 3 other S/R for other types (R4,R8,RS).
5266      Change calls to WRITE_0D/1D_R[4,8,S,L] to match the type of argument.
5267    o eesupp/inc/CPP_EEMACROS.h (EXCH & GLOBAL_SUM/MAX macros):
5268     - ensure suffix (_R4,_R8,_RS,_RL) correspondance between macro and S/R ;
5269     - reduce number of macro definitions (keep only those which are used);
5270       can always call directly the corrresponding S/R if needed.
5271     - everywhere in the code: change macros (EXCH & GLOBAL_SUM/MAX) suffix
5272       _R4/_R8 to _RS/_RL when applied to _RS/_RL variable.
5273     Fixed wrong type of arg in:
5274       atm2d/put_ocnvars.F cheapaml/cheapaml.F ocn_compon_interf/ocn_apply_import.F
5275       ctrl/ctrl_map_ini_ecco.F seaice/seaice_do_diags.F seaice/seaice_model.F
5276     To fix: global_sum of var in common block is wrong (multi-threaded) in:
5277       dic/dic_atmos.F ebm/ebm_area_t.F ebm/ebm_zonalmean.F sbo/sbo_calc.F
5278     To fix: aim_v23/aim_do_co2.F (BARRIER & GLOBAL_SUM within bi,bj loops)
5279    o adjustment.cs-32x32x1: test "blank tiles" when compiling with mpi; 2nd
5280      "nlfs" mpi test is going to stop when checking for unconnected tile egdes.
5281    o eesupp/src: new S/R to stop everyone when 1 (or more) Proc. find an error
5282    o pkg/exch2: new S/R EXCH2_CHECK_DEPTHS to check that unconnected tile
5283      edges are closed (zero depth); might happen with "blank tiles";
5284      for now, disabled if using OBCS.
5285    o tools/gemake2: delete modifs from March 27-29 2009 (with option "-mpi":
5286      link *_mpi files from "MODS" dir) to return to a strait-forward behavior.
5287    o move read_write.F to write_utils.F ; new parameter (maxLengthPrt1D)
5288      to reduce length of 1.D array print in STDOUT.
5289    o adjustment.cs-32x32x1: changed to oceanic test with 1 continent
5290      + use 48 tiles (16x8): this will allow to test "blank tiles".
5291    o start to test MPI + multi-threaded (change testreport to skip tests
5292      where number of tiles do not match).
5293    o genmake2: add option "-omp" to turn on Open-MP ;
5294      passed to testreport (if using -mth) ; merge few (*+mth) optfiles.
5295    o pkg/exch2 (+ utils/exch2): ignore blank tiles (instead of removing them)
5296      and keep the original tile numbering. Note: compatible with old
5297      W2_EXCH2_TOPOLOGY.h & w2_e2setup.F topology files.
5298    
5299    checkpoint61l (2009/04/07)
5300    o Overlaps had been forgotten in calculating ijk keys : fixed
5301    o fix cyrus makedepend for gcc 4.4
5302    o experiment fizhi-cs-aqualev20:
5303      switching to new version of S/R GETPWHERE (#define TRY_NEW_GETPWHERE)
5304      and generate new output. Note: new output is much closer to the old
5305      one (v1.8) generated with pgf77 -O2 on Mar 14 2007 than it is from
5306      the previous one (v1.9) generated with pgf77 -O0 on Jun 13 2007.
5307    o pkg/fizhi:
5308     - change to avoid indices going deliberately over array-bounds
5309     - remove unnecessary MPI stuff
5310     - perpetual spring equinox with "#define FIZHI_USE_FIXED_DAY"
5311     - new version of S/R GETPWHERE available with #define TRY_NEW_GETPWHERE:
5312       does not go over array-bounds and therefore returns reliable output.
5313     - in fizhi_driver.F & fizhi_turb.F, fix "get_alarm" calls:
5314       this S/R has 4 output arguments, which are used inside "get_alarm";
5315       when it is called with the same variable "ndum" in place of several
5316       output arguments, this produces weird side effect inside "get_alarm"
5317      (e.g., datein=dates(n) is overwritten by timein=times(n) since both
5318       datein & timein, resp. 2nd and 3rd arg., are pointed to the same "ndum"
5319       address) and produces error.
5320    o tools/gemake2: (March 27-29 2009)
5321      with option "-mpi": link *_mpi files from "MODS" dir (this is what
5322      testreport does).
5323    o lab_sea experiment: change from 2x1 tiles to 2x2 tiles and regenerate output
5324    o pkg/seaice: fix bug in new version of S/R SEAICE_LSR.F:
5325       update lab_sea.lsr & lab_sea.salt_plume results
5326    o pkg/seaice:
5327      Major overhaul of the LSOR solver: change discretization from original
5328      finite differences to finite volume. The old routine is still in the
5329      file seaice_lsr.F and can be turned on with the CPP-flag
5330      SEAICE_OLD_AND_BAD_DISCRETIZATION
5331      Along with this change, the discretization of the strain rates is changed.
5332      The same flag turns on the old discretization in seaice_calc_strainrates.F
5333      All verification experiments with seaice are affected (except for
5334      seaice_exf_offline); global_ocean.cs32x15/input.icedyn recovers the old
5335      results by setting the above flag.
5336      Further changes involve changes in defaults:
5337      - ALLOW_FLOODING is defined and turned on by default
5338      - SEAICEadvSnow = .true. is now the default
5339      - SEAICEadvSalt = .true. is now the default
5340      - SEAICEadvAge  = .true. is now the default
5341      - SEAICE_clipVelocities  = .false. is now the default
5342                                         (as per J. Zhang's recommendation)
5343      - B-grid, and thus not tested: SEAICE_TEST_ICE_STRESS_1/EXPLICIT_SSH_SLOPE
5344        is defined, SEAICE_TEST_ICE_STRESS_1 is renamed into SEAICE_BICE_STRESS
5345      - seaice_growth: replace computation of UG by a simple copy from wspeed
5346    
5347    checkpoint61k (2009/03/18)
5348    o pkg/seaice: a few bug fixes mostly concerning the metric terms:
5349      seaice_lsr: fixed a few metric terms,
5350                  affects lab_sea.lsr, lab_sea.salt_plume, seaice_obcs
5351                  add more debugging diagnostics
5352      seaice_evp: removed superfluous many metric terms of FV discretization
5353                  of stress divergence
5354                  affects lab_sea, lab_sea.hb87
5355      seaice_ocean_stress: removed superfluous many metric terms of FV discretization
5356                  of stress divergence for non-evp solver
5357                  (this part is not tested anywhere)
5358      seaice_calc_strainrates: fixed a bug in no-slip boundary conditions,
5359                  they were effectively only half slip
5360                  affects lab_sea.hb87
5361      updated all relevant verification experiments (except lab_sea//output_adm.txt
5362        which was left over, but fails at level 7 & 6)
5363    
5364    checkpoint61j (2009/03/17)
5365    o pkg/seaice: turn a few hard wired parameters into run time parameters
5366    o pkg/seaice/exf/monitor: turn netcdf coordinate variable T into model
5367      time in seconds as promised by the usints in seaice_monitor and exf_monitor
5368    o pkg/mnc: fix the coordinate variables for multi-tile curvi-linear grids
5369      that are not cubed-sphere grids
5370    o pkg/seaice: fix a bug for the rare case of SEAICE_VECTORIZE_LSR
5371    o pkg/ctrl:
5372      fix bug in ctrl_depth_ini.F (EXCH_XYZ was applied to 2-D field xx_r_low)
5373    o non-hydrostatic (calc_gw.F):
5374      fix viscA4 on CS-grid + fix diagnostics: Wm_Diss & Wm_Advec
5375      update output of exp. global_ocean.cs32x15.viscA4
5376    o remove backward compatibility for thetaMin,phiMin
5377      (replaced by xgOrigin,ygOrigin on Jan 27, 2009)
5378    o pkg/exf: fix a serious bug in exf_set_uv.F: do a rotation of the
5379      interpolated wind field not only for curvilineargrid=.true., but also
5380      for a rotated grid (rotateGrid=.true.)
5381    o pkg/exf: add capability to bypass interpolation for runoff
5382      by setting yet another CPP-flag
5383    o eesupp/src, B-grid exchange:
5384      add simple (6 tiles, non MPI) CS exch + standard interface S/R.
5385    o autodiff
5386      new CPP option ALLOW_TAMC_SINGLEPREC_COMLEV
5387      allows to switch to single-prec common blocks;
5388      corresponding switch occurs in tamc.h, integer isbyte
5389      TAF store directivs "byte" and "kind" seem equivalent;
5390      Most tamc.h have been updated correspondingly.
5391    
5392    checkpoint61i (2009/02/13)
5393    o autodiff:
5394      fix autodiff_sore/_restore indices for obcs
5395      (spotted by I. Hoteit, M. Mazloff)
5396    o pkg/autodiff, pkg/ctrl:
5397      Add flag to reduce all tapelev I/O to single-prec.
5398      In data.ctrl set
5399        doSinglePrecTapelev = .TRUE.
5400    o model/src/ini_curvilinear_grid.F, new grid-file format without EXCH2:
5401      check in hack for SX8 compiler (for dxV, dyU); remove it afterwards.
5402    o pkg/shelfice: fix bug with SHELFICEconserve flag, prepare for
5403      real fresh water flux (not yet)
5404    o pkg/mdsio & rw:
5405     - add argument & option to S/R MDS_WRITEVEC_LOC (avoid Open/Close & write-meta)
5406     - add simple interface S/R to MDS_WRITEVEC_LOC in pkg/rw: WRITE_GLVEC_RX.
5407    o pkg/flt:
5408     - replace FLT_INIT by 3-steps standard initialization S/R: readparms,
5409       init_fixed & ini_varia.
5410     - clean-up & simplify linear interpolation S/R:
5411       move flt_bilinear.F -> flt_interp_linear.F ; add arg. myThid.
5412     - fix some indices (mainly vertical index) ; add IMPLICIT NONE.
5413     - more efficient I/O, using new options of MDS_WRITEVEC_LOC S/R.
5414     - add vert. coordinate & horiz. indices to output files.
5415     - change vertical position in initial condition, from index to depth [m].
5416     - store horizontal (decimal) indices i,j in common block (instead of coord. x,y)
5417       (easier to get to a curvilinear grid) ; delX,delY no longer used.
5418    o pkg/ggl90: a few modifications:
5419     - fix bottom boundary condition, and interpolation of KappaE
5420       near top and bottom
5421     - use same set of viscosity/diffusivity for TKE/momnetum/tracer
5422     - add smoothing option as in Blanke and Delecluse (1993) (--> ALLOW_GGL90_SMOOTH)
5423     - add a few options for mixing-length upper limit (--> mxlMaxFlag)  
5424    o rename thetaMin,phiMin -> xgOrigin,ygOrigin
5425      (maintain temporary backward compatibility, until next checkpoint)
5426    
5427    checkpoint61h (2009/01/27)
5428    o pkg/diagnostics with "periodic averaging diagnostics":
5429      fix S/R DIAGNOSTICS_COUNT ; hack diagnostics_out.F to get NetCDF output.
5430    o pkg/my82: add missing "_d 0" ; update output of exp. vermix.my82
5431    o pkg/obcs: fix loop ranges for balancing code
5432    o pkg/flt:
5433     - improve criteria for finding which tile owns a float.
5434     - fix FLT_EXCH for case without MPI ; apply cyclic BC + fix also the MPI case.
5435    o Add well-mixed CO2 box in aim_v23 (which includes changes in pkg
5436      aim_compon_interf, ocn_compon_interf, gchem, and dic to get coupling
5437      with ocean biogeo)
5438    o pkg/flt:
5439     - do some cleaning and fix the restart ;
5440     - add output.txt in flt_example/results to get this pkg tested.
5441    o genmake2: add an EXTENDED_SRC option and flag.
5442       for now, cannot be turned on on command line (only through genmake_local)
5443    o pkg/mdsio: read/write vector:
5444     - singleCpuIO: fix RL/RS in MDSWRITEVECTOR by calling new S/R MDS_BUFFERtoRL/RS
5445     - singleCpuIO=F: fix arrType & filePrec & _BYTESWAPIO in both MDSREADVECTOR
5446       & MDSWRITEVECTOR by calling new S/R MDS_RD/WR_VEC_RL/RS.
5447     - affects gradient of test-exp "bottom_ctrl_5x5" (not due to _BYTESWAPIO)
5448      (drop to 4 digits matching for grad). But this test does not look very
5449      reliable (was already failling on eddy, fc5, at 6.digits). Update output.
5450    
5451    checkpoint61g (2008/12/29)
5452    o pkg/flt:
5453      - move FLT_CPPOPTIONS.h to FLT_OPTIONS.h (standard name)
5454       + make OPTIONS file more standard.
5455      - rename S/R MDSREADVECTOR_FLT to FLT_MDSREADVECTOR (to mach src file name)
5456      - fix _BYTESWAPIO CPP-Flag
5457      - standard reading of file-parameter "data.flt"
5458      - fix argument list of S/R FLT_RESTART
5459      still need to fix _BYTESWAPIO in pkg/mdsio/mdsio_writevector.F
5460    o pkg/obcs: fix a CPP-flag, bug reported by Jeff Blundell
5461    o gather_2d.F/scatter_2d.F: suppress vectorisation on NEC SX in respond to
5462      a still unfixed compiler/optimization bug
5463    
5464    checkpoint61f (2008/11/21)
5465    o pkg/seaice, LSR solver: fix bug in GLOBAL_MAX calls ;
5466      update results of global_ocean.cs32x15.icedyn test.
5467    o move getcon.F from model/src to pkg/fizhi.
5468    o pkg/exf: add parameter for extrapolation of temp up to the surface
5469       and option to prevent negative evap (in bulk_largeyeager04 only).
5470    o Prather Advection scheme: fix tracer conservation for divergent flow
5471      (e.g., when using NonLin Free-Surface).
5472    o kpp: retire KPPmld diagnostics --> use MXLDEPTH instead
5473    o gmredi (Visbeck-variable-K):
5474     - add more parameters to Visbeck-variable-K.
5475     - use a 5 points average for dSigmaR in Visbeck-K calculation
5476       (more "homogenous": same stencil and same weights as in dSigmaH)
5477     - update output of ideal_2D_oce experiment.
5478    o fix CPP-flag REAL4_IS_SLOW, when _RS expands into real*4
5479      (#undef REAL4_IS_SLOW)
5480     - pkg/mnc/mnc_cw_cvars.F: write _RS-grid variable as netcdf-real*4
5481       coordinate variable
5482     - pkg/monitor/monitor.F: call mon_printstats_rs for _RS variables
5483       (surface forcing fields), removes some of the functionality
5484     - model/src/write_grid.F: write _RS variables as RS-netcdf variables
5485     - model/src/diags_oceanic_surf_flux.F: fix a few diagnostics, but
5486       probably not all: copy _RS surface flux fields to RL field before
5487       calling DIAGNOSTICS_FILL
5488     - model/inc/CPP_EEMACROS.h: make the _EXCH_*_RS macros expand into
5489       real*4 (CALL EXCH_*_RS) versions.
5490     - tested in 2 experiments: inverted_barometer & solid-body.cs-32x32x1
5491       (generate new output).
5492    
5493    checkpoint61e (2008/10/23)
5494    o gmredi (Visbeck-variable-K):
5495      - fix the "OLD_VISBECK_CALC" option + move the #undef to GMREDI_OPTIONS.h
5496      - change computation of Visbeck-K where Slope > Smax :        
5497        now: N*min(Slope,Smax) (similar to OLD_VISBECK_CALC with gkw91 taperFct)
5498        previously was: M*sqrt(min(Slope,Smax)) ; update ideal_2D_oce output.
5499    o bottom-drag in P-coord.: change units of bottomDragLinear & bottomDragQuadratic
5500      to be the same as with Z-coord. (i.e., m/s & no-units respectively).
5501    o calc_viscosity: fix index range (was wrong for CD-Scheme & explicit Visc)
5502    o pkg gmredi, linear & fm07 tapering: put an upper limit on Slope^2 so that Kwz
5503      does not become too large (to avoid precision problems in implicit-diffusion
5504      solver); update ideal_2D_oce output.
5505    o pkg ggl90:
5506      - in ggl90_cal.F: compute only one set of visc/diff, used to
5507        step forward TKE/T/S/momentum
5508      - default value of GGL90viscMax/GGL90diffMax larger and equal (to
5509        have Prandlt =1)
5510    o gmredi (fm07):
5511      - add lower limit on Transition layer thickness + lower limit on 1/lambda
5512      - allow to set few more params from data.gmredi
5513    o pkg ggl90:
5514          - add missing sqrt(2) factor in computation of mixing length
5515            scale in ggl90_calc.F
5516            (see Eq. (2.35) in Blanke and Delecluse, JPO, 1993)
5517    
5518    checkpoint61d (2008/09/25)
5519    o adjoint modifs
5520      - adapt to new field rhoInSitu
5521      - allow to revert from StoreDynVars2D, StoreDynVars3D
5522        to individual fields
5523        (switches AUTODIFF_USE_OLDSTORE_2D, AUTODIFF_USE_OLDSTORE_3D)
5524    o store 3-D (in-situ) density in commom block (DYNVARS.h)
5525     - save 1 rho computation.
5526     - no longer modify T & S inland when using down_slope pkg.
5527    o gad_som : allow to switch to SOM advection for T & S without corresponding
5528      pickup files (using new S/R: MDS_CHECK4FILE).
5529    o keep removing _BEGIN/_END_MASTER between MDSIO S/R call
5530      (for useSingleCpuIO to work in multi-threaded)
5531    o pkg/shelfice:
5532     - disentangle parameters: retire shelfIceFile in data/PARM05 and substitute
5533       with SHELFICEtopoFile in data.shelfice
5534     - move code for reading ice shelf topography and modifying hFacC into separate
5535       subroutines of the shelfice package
5536     - separate initialisation of "fixed" and "variable" variables
5537     - kTopC is not (yet) replaced by kSurfC, although this is possible
5538    o fix broken diagnostic SIatmFW and changed the units from m/s to kg/m^2/s
5539    o add initialisation of deepFac if using Pcoords (new S/R set_grid_factors)
5540      and rename:
5541      ini_phiref.F          --> set_ref_state.F  (+ set anelastic factors)
5542      ini_reference_state.F --> load_ref_files.F (- set anelastic factors)
5543    o change FIND_RHO_SCALAR : return rho (instead of rho - rhoConst)
5544    
5545    checkpoint61c (2008/08/30)
5546    o add option ALLOW_ADDFLUID and run-time selector "selectAddFluid"
5547      to add mass source/sink of fluid in the interior (3-D generalisation
5548      of oceanic real-fresh water flux).
5549    o pkg/monitor: fix recip_dr argument in mon_advcflw2 call (-> advcfl_W_hf_max)
5550    o vermix test experiment: switch from LINEAR EOS to MDJWF (not tested before)
5551    o new pkg: down_slope
5552      density-driven downsloping flow parameterisation (Tellus, 1999, 412-430).
5553      - presently, modify T & S inland (dwnslp_calc_rho.F).
5554        can be avoided if rho was stored in common bloc and used in calc_phi_hyd.
5555      - implementation for ocean in P-coords not tested.
5556      - add secondary test to global_ocean.90x40x15 (input.dwnslp) to check this pkg.
5557    o move kSurfC,kSurfW & kSurfS from SURFACE.h to GRID.h (next to kLowC)
5558      (to facilitate conversion of oceanic pkg to p-coordinate).
5559    o change FIND_RHO to FIND_RHO_2D :
5560      pass arguments tFld & sFld as local (tile) 2D-arrays ; +fix EOS_CHECK.
5561    o new pkg: cheapaml
5562    
5563    checkpoint61b (2008/08/05)
5564    o exch2:
5565      change index bounds in rx2_cube exchanges (new S/R: EXCH2_GET_UV_BOUNDS)
5566      - no longer depend on the order sequence (N,S,E,W).
5567      - 3rd exchange no longer needed (tested with 24 tiles).
5568      - same modif to hand-written adjoint S/R (global_ocean.cs32x15: zero diff)
5569      - exch_UV_A-grid readily available (but not yet tested).
5570      comment out 3rd exch call and remove copy of V to U at SE & NE face-corners
5571      (both are no longer needed) in exch_uv: no effect in forward run; but
5572       get truncation error differences with adjoint exch.
5573    o exch2:
5574     - change index-bounds storage (moved from target to local tile,
5575       more intuitive this way) ; rename/remove some variables.
5576     - change utils/exch2/matlab-topology-generator & code_mods accordingly.
5577    
5578    checkpoint61a (2008/07/29)
5579    o exch2/matlab-topology-generator:
5580      fix bug in index bounds for N-S internal exchange (hard to tell if this
5581      had any effect on the solution).
5582    o pkg/mnc: small fix in mnc_handle_err: make sure that length of msgbuf
5583      is exceeded
5584    o testreport: modify syntax of awk, so that it works also with
5585      awk, and not only with nawk and gawk
5586    
5587    checkpoint61 (2008/06/24)
5588    o autodiff
5589      Change default for TAF usage by removing argument '-nonew_arg'
5590      This changes TAF subroutine argument list (ordering of active var.)
5591      Omission of this flag leads to incompatibility w.r.t. TAMC
5592      To restore TAMC-compatibility, need following modifs:
5593      * use adoptfile tools/adjoint_options/adjoint_tamc_compatibility
5594      * use CPP option #define AUTODIFF_TAMC_COMPATIBILITY
5595      Tested TAF version is 1.9.22
5596      N.B.: exch2 hand-written adjoint code currently not TAMC compatible
5597    
5598    checkpoint60 (2008/06/19)
5599    --->>> This is the last checkpoint for which generating the adjoint
5600    --->>> is done via the TAMC-compatibility TAF-flag "-nonewarg"
5601    --->>> by default.
5602    --->>> Future checkpoints will ommit this flag by default.
5603    o pkg/generic_advdiff, os7mp: simplify and avoid division by zero.
5604    o pkg/grdchk: Add gradient check to etan0 perturbations.
5605    o pkg/exf: read ice area from file (#ifdef ALLOW_ICE_AREAMASK).
5606    o pkg/autodiff: more flexibility in zeroadj.
5607      model/src: modifying do_oceanic_phys.F accordingly.
5608    o pkg/ctrl: Bounds for (kapgm,kapredi,eddypsi) parameter estimation.
5609    o model/src and pkg/gmredi: GMREDI_WITH_STABLE_ADJOINT CPP option
5610      special setup of gmredi for which the adjoint is stable
5611      enough for parameter optimization.
5612    o bridging the gap between eddy stress and GM.
5613      -> eddyTau is replaced with eddyPsi (eddyTau = f x rho0 x eddyPsi)
5614          along with a change in CPP option (now ALLOW_EDDYPSI).
5615      -> when using GM w/ GM_AdvForm:
5616          The total eddy streamfunction (Psi = eddyPsi + K x Slope)
5617          is applied either in the tracer Eq. or in momentum Eq.
5618          depending on data.gmredi (intro. GM_InMomAsStress).
5619      -> ALLOW_EDDYPSI_CONTROL for estimation purpose.
5620      The key modifications are in model/src/taueddy_external_forcing.F
5621      pkg/gmredi/gmredi_calc_*F pkg/gmredi/gmredi_*transport.F
5622    
5623    checkpoint59r (2008/05/29)
5624    o new S/R (pkg/mdsio/mdsio_facef_read.F) reading of sNx+1 x sNy+1 array
5625      from per-face file (take S/R READSYMTILE_RS out of ini_curvilinear_grid.F);
5626      fix option to read coriolis(@ cell-corner) from files with CS-grid.
5627    o pkg/mnc: add some attributes to standard 1D-coordinate variables
5628    o pkg/diagnostics: enforce missing_value attribute for scalar variables at
5629      mass points, when using mnc for output
5630      - add runtime parameter (missing_value, missing_value_int) to override
5631        default (which is the value of getcon('UNDEF'))
5632    o pkg/mnc: prepare mnc for the actual use of missing values with the
5633      diagnostics package: small fix in mnc_cw_readwrite.template and more
5634      initialisation of never used fields
5635      - replace mnc_common.h and mnc_id_header.h with corresponding upper case
5636      versions
5637    o pkg/thsice/thsice_ini_vars.F added default initial values so that
5638      thermodynamics sea ice solver does not blow up when some initial fields
5639      are missing.
5640    o move from external_forcing_surf.F to ini_forcing.F
5641      the p-coord. hack consisting in using pLoad to set phi0surf ;
5642      update output of tutorial_global_oce_in_p (affected @ truncation level).
5643    o Freshen up a bit hs94.1x64x5, notably:
5644      remove rotationPeriod and tRef=5*0. (adjoint only), and add
5645      exactConserv=.TRUE.
5646    o pkg/generic_advdiff:
5647      change option GAD_ALLOW_SOM_ADVECT to GAD_ALLOW_TS_SOM_ADV which only
5648      applies to files where Temperature & Salinity 2nd Order moments are used.
5649    o pkg/ptracers: add second-order moment advection schemes (80 and 81);
5650      this uses a dynamically allocated internal state data structure
5651      (#define PTRACERS_ALLOW_DYN_STATE in PTRACERS_OPTIONS.h)
5652      and requires a fortran 90 compiler
5653    
5654    checkpoint59q (2008/05/06)
5655    o pkg/mom_vecinv: Add energy & enstrophy conserving scheme (selectVortScheme=3)
5656       (from Sadourny, described by Burridge & Haseler, ECMWF Rep.4, 1977)
5657    o Refresh tutorial_global_oce_biogeo, notably:
5658      - change bathymetry (put back seamounts in ACC, use hFacs)
5659      - change EOS (POLY3 --> JMD95Z)
5660      - use Bryan-Lewis vertical diffusivity
5661      - use multidimensional advection
5662      - remove old virtual virtual in dic pkg, now done through ptracer pkg
5663      - change a couple of parameters in dic pkg
5664    o pkg/ctrl: change formula in adctrl_bound.F and add a parameter to ctrl_map_ini_gen.F
5665    o pkg/obcs: change default to OBCSfixTopo = .true.,
5666      - set OBCSfixTopo=.false. in exp4/input/data.obcs to reproduce old result
5667      - replace "debugMode" with "debugLevel .GE. debLevB"
5668    o implementation of TAF directives for gchem,cfc,dic
5669    o remove "exp5" (replaced by tutorial_deep_convection).
5670    o pkg/obcs: add code to fix topography gradients normal to open boundaries;
5671      this requires computing the index fields OB_Jn/Js/Ie/Iw in obcs_readparms;
5672      the code can be turned on by setting OBCSfixTopo = .true. in data.obcs
5673      --> changes results in exp4, seaice_obcs
5674    o tutorial_deep_convection :
5675      update the set-up and increase resolution and domain size ; start
5676      from pseudo initial conditions = output at t=120mn in order to see
5677      something happening when running testreport.
5678    o pkg/seaice: add os7mp as an advection scheme
5679                  add check for advection schemes
5680                  add a flag for restoring T and S underneath sea ice
5681    o pkg/my82: add netcdf-support and diagnostics
5682    o thsice pkg:
5683      - Now hsMax limits snow height by turning it into ice following
5684        flooding scheme (and now conserving energy)
5685      - Slight rewriting of the formula in thsice_calc_thick.F
5686      - Parameter rhowi eliminated to be replaced by floodFac = (rhosw-rhoi)/rhos
5687      --> changes results of global_ocean.cs32x15.icedyn and global_ocean.cs32x15.thsice
5688    
5689    checkpoint59p (2008/04/10)
5690    o gchem / dic / cfc :
5691      - add useDIC, useCFC , read from "data.gchem" (& hold in GCHEM.h);
5692      - add new parameter files: "data.dic" & "data.cfc" ;
5693      - various re-arrangement in initialisation & header file ;
5694      - fix tutorial_global_oce_biogeo for multi-threaded test.
5695    o pkg/dic: test for "pickup_dic" file when restarting ;
5696      if no pickup-file, can restart with a re-initialised pH (same as it did
5697      before) providing pickupStrictlyMatch is set to False.
5698    o change argument list of S/R PTRACERS_WRITE_PICKUP & MYPACKAGE_WRITE_PICKUP
5699      + fix call to S/R GGL90_WRITE_PICKUP & DIC_WRITE_PICKUP
5700    o add a "warning" (to Error msg file) when an Active Tracer is not using AB-2
5701      and staggerTimeStep is off (needed for stability of Internal-wave dynamics).
5702    o move out of PARAMS.h & data the last pieces of old-ptracer code: tauTr1ClimRelax,
5703     & lambdaTr1ClimRelax ; put those 2 params in PTRACERS_PARAMS.h & data.ptracers
5704       (note: not clear to me what lambdaTr1ClimRelax is still used for ...)
5705    o pkg/mom_vecinv: - new parameter "selectVortScheme" to select which
5706       scheme to use for vorticty-term ;
5707     - compute upwindVorticity=T case within mom_vi_u/v_coriolis_c4.F
5708       (with default selectVortScheme, return to original discretisation)
5709     - remove weird combination (e.g.: upwindVorticity & highOrderVorticity)
5710    o pkg/seaice: add a line to the summary to indicate grid type (B/C)
5711    o in mom_calc_visc, fix average value of viscAh_W & viscA4_W next to the
5712      bottom ; only used with variable horizontal viscosity and non-hydrostatic.
5713      also fix diagnostics VISCAHW & VISCA4W.
5714    
5715    checkpoint59o (2008/03/07)
5716    o dome/code/obcs_calc.F: avoid division by zero (detected using gfortran).
5717    o change the loop ordering in most gad_*_adv_x.F to improve vectorization:
5718      move a few statemens out the main loop into separate loops
5719    o pkg/shelfice:
5720      - sort out freshwater flux; convert freshwater fluxes to mass fluxes
5721        (kg/m^2/s), does not break tests, because in verification/isomip,
5722        rhoConstFresh=rhoConst (by accident)
5723      - rearrange computation of tLoc, sLoc, pLoc to make code more efficient
5724      - move S/R find_rho_scalar, pkg/ecco/sw_ptmp.F, pkg/ecco/sw_adtg.F into
5725        new file model/src/seawater.F, so that they are available for all pkgs.
5726      - convert potential temperature into in-situ temperature. This changes the
5727        isomip tests => update tests
5728    o add a flag writePickupAtEnd (default=true) to be able to suppress
5729      writing a pickup at the last timestep
5730    o tools/mpack-1.6 :
5731      - disable automake (not working) and autoconf (not needed).
5732      - update to version 1.6.4 which fix MD5 code on some 64 bits platforms
5733        also cleaner with much less compilation warnings.
5734    o pkg/profiles:
5735      rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg
5736      (for "less than 32 characters name" compiler requirement)
5737    o pkg/obcs and pkg/exf: added capability to specify seaice open boundary
5738      conditions that have a different sampling frequency than S/T/U/V obcs
5739    o pkg/diagnostics (stats-diags):
5740      - fix global Min/Max in case 1 processor get only empty tiles
5741    o genmake2: replace (4 times)
5742         make genmake_tc_1.o >> genmake_warnings 2>&1
5743      with
5744         COMM="$CC $CFLAGS -c genmake_tc_1.c"
5745         echo $COMM >> genmake_warnings
5746         $COMM >> genmake_warnings 2>&1
5747      to make genmake2 always see the value of CC as specified in the optfile.
5748    o generic_advdiff: - prather advection scheme (SOM) coded for CS-grid.
5749      - add diagnostics for 1srt & 2nd Order moments and sub-grid variance.
5750      - modify verification advect_cs test to test SOM-advection on CS-grid.
5751    o pkg/ctrl:
5752      - Rewrite of ctrl_map_ini_ecco.F,
5753        introducing a generic routine (ctrl_map_ini_gen.F).
5754      - Modification of ctrl_bound/adctrl_bound handling control vector bounds.
5755    
5756    checkpoint59n (2008/02/09)
5757    o pkg/diagnostics: for large number of diagnostics, store diagnostic mate
5758      number in dedicate array "hdiag":
5759      - new version of S/R DIAGNOSTICS_ADD2LIST : DIAGNOSTICS_ADDTOLIST
5760        with 1 more argument (mate number); modify old version DIAGNOSTICS_ADD2LIST.
5761      - many small changes (integer format) for large number of diagnostics
5762      - start to use DIAGNOSTICS_ADDTOLIST (necessary for diagnostics with
5763        a counter mate) in pkg diagnostics, ptracers, thsice & aim_v23.
5764    o add parameter rotateGrid and Euler angles EulerPhi/Theta/Psi. For
5765      usingSphericalGrid, this allows to define the rotated grid coordinates
5766      via phiMin/thetaMin/dxSpacing/dySpacing, etc., but then re-compute the
5767      geographical coordinates according to the inverse of the rotation defined
5768      by the Euler angles, so that Coriolis parameter and online-interpolation by
5769      exf works with the geographical coordinates on XC/YC/XG/YG.
5770      Naturally, this feature does not work with all packages, so some
5771      combinations are prohibited in config_summary (flt, flt_zonal, ecco,
5772      profiles), because there the coordinates are assumed to be regular
5773      spherical grid coordinates.
5774    o pkg/gmredi,ctrl,ecco,autodiff,grdchk and model/src,inc:
5775      - introduce isopycnal diffusion coefficient control.
5776    o tools/adjoint_options:
5777      - additional control vector components.
5778    o pkg/mnc: have mnc create marginally meaning full coordinate variables
5779      (that is the grid indices) if usingCurvilinearGrid and NOT EXCH2
5780    o pkg/mypackage:
5781      - add example of read/write pickup for state-var ;
5782      - add entry points to the main code for state-vars diags & write-pickup.
5783    o pkg/exf: rewrite of exf_getffieldrec.F to properly deal with year
5784      transitions for useExfYearlyFields
5785      - add new subroutine that determines the file to read from for
5786        use*YearlyFields = .TRUE. and .FALSE.
5787      - add a verification experiment to global_with_exf that tests
5788        useExfYearlyFields with USE_EXF_INTERPOLATION defined
5789    o pkg/obcs/exf: add useOBCSYearlyFields (=.FALSE.) to obcs with exf in
5790      analogy to useExfYearlyFields; rearrange obcs_prescribe_read: two new
5791      subroutines (which could be generated from a template, because they are
5792      almost identical), for now they are included in obcs_prescribe_read.F for
5793      simplicity
5794    o pkg/exf:
5795      - add a little more diagnostic to exf_interp_read (in analogy to
5796        mds_read_field, can be turned off with debugLevel < debugLevA=1)
5797      - improve vectorizability of exf_interp for TARGET_NEC_SX, makes code
5798        ugly but fast by unrolling short inner loops, inserting a unroll=8
5799        directive in routine lagran, and splitting a loop and making do while the
5800        outermost loop (the latter requires the intoduction of index arrays)
5801    o pkg/obcs: replace obcs_apply_area/heff/hsalt/hsnow with obcs_apply_seaice
5802    o pkg/seaice: moved DIFFERENT_MULTIPLE from seaice_model to seaice_dynsolver
5803      http://forge.csail.mit.edu/pipermail/mitgcm-devel/2008-January/003173.html
5804    o verification/seaice_obcs: updated for restart test and latest options
5805    o pkg/seaice: add a new flag SEAICEuseTEM to use a slightly different
5806      ice rheology (so-called truncated ellipse, that gets rid of tensile stress);
5807      for now this is only available for the C-grid code and also within
5808      #ifdef SEAICE_ALLOW_TEM, because this option may slow down the EVP code
5809    
5810    checkpoint59m (2008/01/14)
5811    o pkg/seaice: use different time constant for melting (SEAICE_gamma_t)
5812      and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature
5813    o gad_som : fix flux output (& diagnostics) to have same units as other  
5814      advection scheme fluxes (was previously multiplied by deltaT).  
5815    o added verification/seaice_obcs both to test seaice open boundaries
5816      and to provide an example matlab scrpt for generating them
5817    o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume
5818    o pkg/salt_plume: clean up salt_plume_frac.F to
5819      remove redundancy in PlumeMethod 1 and 4
5820    o pkg/kpp: added saltplume diagnostics
5821    o pkg/obcs and pkg/seaice:
5822      - do not set uice and vice to zero when OB*icefile are unspecified
5823      - OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default
5824      - moved seaice tracer obcs after call to seaice_growth
5825    o pkg/salt_plume: added various options for salt plume depth
5826      criterion and for vertical distribution of the salt
5827    
5828    checkpoint59l (2007/12/18)
5829    o pkg/ptracers: new version of ptracers pickup:
5830      read meta file and write only fields which are needed to restart.
5831      ( same logic as main pickup file ; also using pickupStrictlyMatch )
5832    o pkg/seaice:
5833      - add timescale for melting due to warm mixed layer as a means of
5834        setting SEAICE_availHeatFrac more conveniently
5835      - add a CPP-flag/runtime parameter check for flooding algorithm
5836      - reformulated availHeat in seaice_growth.F to be independent of AREA
5837    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
5838      unit changes
5839    o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
5840    o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
5841      SX vector computer.
5842    o pkg/seaice:
5843      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
5844        seaice forcing fields can now be read only through pkg/exf
5845      - removed some unused halos
5846    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
5847    o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
5848      or U/VICE from U/VWIND before computing U/VSTRESS
5849    
5850    checkpoint59k (2007/11/30)
5851    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
5852      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
5853    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
5854      all experiments pass when compile with un-initialised var. checking option.
5855    o added pkg/salt_plume
5856    o script to test restart (for now, in MITgcm_contrib/jmc_script)
5857    o pkg/seaice: new read/write pickup version.
5858      read meta file and write only fields which are needed to restart.
5859      ( same logic as main pickup file ; also using pickupStrictlyMatch )
5860    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
5861    o lab_sea.hb87: modify the domain & update output.hb87.txt :
5862      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
5863      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
5864      process. Fixed here by closing the domain at the Northern boundary.
5865    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
5866    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
5867      a set of consecutive levels in/from a 3-D array.
5868    o pkg/ptracers:
5869      use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
5870      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
5871    
5872    checkpoint59j (2007/11/09)
5873    o in pkgs: dic, obcs, offline, rbcs:
5874      standard way to compute coeff. for time interpolation between 2 time reccords
5875      which retains full precision (& make results less dependent on compiler).
5876      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
5877    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
5878      packages instead of reading ice cover and wind speed separately
5879    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
5880     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
5881      to allow to compile customized code before the update)
5882    o cleaning-up:
5883      - fix CPP instruction syntax in pkg/obcs
5884      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
5885        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
5886      - fix some threads issue in IO parts.
5887    o pkg/dic:
5888      - add tons of "_d 0" (--> much better testreports !)
5889       and then update outputs of tutorial_global_oce_biogeo
5890    o pkg/mom_fluxform:
5891      add a special version of momentum advection intended to conserve momentum
5892      next to a bathymetry step or a coastline edge. (default = off = #undef)
5893    o new read/write pickup version:
5894      - for now, only implemented for main (mdsio) pickup file.
5895      - write out only what is needed to restart; merge pickup_nh , pickup_ph
5896        and main pickup together.
5897      - read meta file; read only what is needed to restart; stop if a field
5898        is missing (if pickupStrictlyMatch=T, = the default) or try to restart
5899        if it make sense (even if the restart is not perfect).
5900      - if no meta file, assume that pickup to read corresponds exactly to
5901        a pickup that would currently be written.
5902      - read pickup written in the old format (until checkpoint59i) if it
5903        recognizes an old meta file (no field-list).
5904      - add a meta file in exp. which starts from a pickup: 2 cases:
5905        a) minimal meta file (with just file precision) + pickupStrictlyMatch=F
5906         e.g.: global_ocean.90x40x15/input/pickup.0000036000.meta
5907        b) a meta file describing the content of the associated pickup file
5908         e.g.: tutorial_global_oce_biogeo/input/pickup.0004248000.meta
5909    o pkg/mdsio & pkg/rw:
5910      - new routine to read a meta file ; new set of routine to read
5911        Multiple-fields file (with meta file).
5912    o added open boundary conditions capability for seaice
5913        HSNOW, HSALT, UICE, and VICE
5914    
5915    checkpoint59i (2007/10/21)
5916    o adjoint:
5917      * fix multiDimAdvection adjoint
5918        (partial recomputation problem by TAF for fVerT(:,:,kDown)
5919        and comlev1 size definition (maxpass vs. max. number of tracers)
5920      * verification/global_ocean.90x45x15 adjoint now tests
5921        NLFS and multiDimAdvection using DST3 (=30)
5922      * verification/lab_sea now tests multiDimAdvection using DST3 (=30)
5923    o pkg/kpp: add "_d 0" to real constant (if missing);
5924      update output of exp: natl_box (10.digits); vermix (std, 7.digits)
5925      and lab_sea, 3.FW (only 6,4,6 digits match) & AD (8.digits).
5926    o prepare for "clever pickup" implementation: add new header file "RESTART.h"
5927      for internal parameters related to restart process (formerly from PARAMS.h)
5928      and add startAB parameter to argument list of S/R ADAMS_BASHFORTH2.
5929    o more standard interface to {PKG}_WRITE_PICKUP with pickup suffix passed
5930      as argument. (only atm2d & obcs write_pickup have not yet been updated)
5931    o pkg/monitor:
5932      - use GLOBAL_SUM_TILE instead of _GLOBAL_SUM
5933      - fix mon_stats_rs (statistics over the full domain, even where field is zero)
5934      - account for deep Atmosphere factor and density factor (anelastic)
5935    o added open boundary conditions capability for seaice HEFF and AREA
5936    o pkg/shelfice: add option for convservative form of Hellmer&Olbers (1989)
5937      thermodynamics
5938      - requires a little reorganization, which affects the testreport results
5939        of isomip.htd (only 7 digits of cg2d agree) => update/modify experiment,
5940        so that now the conservative form is tested
5941      - add a few comments
5942    o add missing cvs Header: or Name: in eesupp/*, pkg/* & verification/code*
5943    o add a little bit of code to gad_os7mp_adv_?.F to help vectorization
5944    o add new diagnostics to seaice: advective, diffusive fluxes (only for
5945      multidim-advection, for scheme 2 they are not filled) and transports,
5946      thermodynamic growth rates
5947    o change units of EmPmR (inside the code, + within coupling interface)
5948      from m/s to kg/m2/s (mass flux) but leave input file unchanged.
5949      Affects results @ truncation level (cg2d match) and update output of
5950       experiments: lab_sea(6), global_ocean.90x40x15(10),
5951      global_ocean.cs32x15(11x3,10), natl_box(11), tutorial_global_oce_latlon(11)
5952      + adjoint results: global_ocean_ebm(11) and lab_sea (12).
5953      Coupled set-up: allow to restart from previous pickups (cpl_oldPickup=T).
5954      Next: will retire convertEmP2rUnit (simply using mass2rUnit instead).
5955    
5956    checkpoint59h (2007/09/29)
5957    o pkg/exf:
5958      - improve vectorization by moving if-statement out of loops in
5959        exf_mapfields, exf_radiation
5960      - exf_bulkformulae.F: introduce 2D fields and vectorize code
5961    o pkg/kpp: added the salt plume scheme (ALLOW_SALT_PLUME) to KPP package
5962    o testreport:
5963      - allow to test for Qnet & SeaIce monitor output; clean-up ALLOW_BULK_OFFLINE
5964        monitor & update offline_exf_seaice exp. output.
5965      - AD testing: pass/FAIL according to Grad. output accuracy (instead of Cost)
5966    o pkg/seaice:
5967      - bug fix in the evp solver: boundary conditions were affected be
5968        masking of zMax/zMin (changes results)
5969      - minor bug fix in boundary conditions in seaice_calc_strainrates
5970        (changes results for no_slip)
5971      - seaice_lsr.F: make interpolation of eta dependent on boundaries
5972      - replace hardcoded lower limit for zeta (zMin) by runtime parameter
5973      - add a test to lab_sea, that tests the Hibler and Bryan (1987) ocean
5974        stress formulation and no-slip boundary conditions
5975    o pkg/ptracers: Temporary fix for PTRACERS_useGMRedi & PTRACERS_useKPP
5976      in gad_calc_rhs.F ; add few safety stops in initialisation phase.
5977    o pkg/seaice: a first HSALT time stepping equation has been checked in
5978    o pkg/seaice: replaced maskW with seaiceMaskU and maskS with seaiceMaskV
5979      in seaice_lsr.F; this solves the pkg/seaice-pkg/obcs problem
5980      without requiring DO-IF statements
5981    o pkg/thsice:
5982      use continuous power-law function for partition of energy between lateral
5983      melting/freezing and thinning/thickening ; old code using step function
5984      still available with #undef THSICE_FRACEN_POWERLAW
5985      update output of exp: aim.5l_cs.thSI, global_ocean.cs32x15.icedyn & .thsice
5986    o testreport: change AD testing : check against results/output_adm.txt
5987      using same scripts as for forward test.
5988    
5989    checkpoint59g (2007/09/17)
5990    o adjoint testing: in preparation for changing testreport:
5991      - output format: cost and grad written on separated lines
5992      - ad output results in directory "results" (instead of "results_ad")
5993    o pkg/seaice: adding ice salinity HSALT as a prognostic variable
5994    o pkg/seaice: changes for using pkg/seaice with pkg/obcs
5995    o pkg/ecco: allow user defined cost function contributions
5996    o testreport:
5997      Allow to choose (per experiment) the list of tested output variables
5998       and the main variable (used to issue a pass/FAIL ) ;
5999      - for now, done by adding the specific list in file: [exp]/input/tr_checklist
6000      - default is unchanged: >cg2d< , (T,S,U,V,5 tracers)_[min,max,mean,StD] ;
6001      Also modify printing of summary:
6002       a) ">" NN "<" indicates the "main" variable (used for pass/FAIL)
6003       b) echo the list of tested variables in the individual summary.txt of
6004          each experiment.
6005    o new S/R GLOBAL_SUM_TILE to compute global sum independently of number of
6006      threads and number of processes (with #define GLOBAL_SUM_SEND_RECV)
6007      (but still depend on the tile decompostion of the domain).
6008    o pkg/seaice: change a discretization detail to make the B-grid code
6009      "more symmetric". This change is likely to remove all "ridges/leads" that
6010      where quasi-aligned with the grid in B-grid solutions. It may also be
6011      the solution to the stress coupling issues with the B-grid.
6012    o each tested exp: add a "run" directory with a standard ".cvsignore" file ;
6013      remove .cvsignore from input dir. (since testreport no longer run here).
6014    o pkg/thsice:
6015     - cleaning: move common block out of "THSICE_2DYN.h" (removed) to "THSICE_VARS.h"
6016     - fix reshaping of sea-ice just after advection:
6017       melt all the ice only if ice-volume is too small.
6018     - re-visit lateral/thinning repartition of melting (modifs from May 04, 2007):
6019       prevent lateral melting if sea-ice fraction is too close to iceMaskMin ;
6020     and update experiment global_ocean.cs32x15.icedyn (+start from pickup files).
6021    o external_forcing_surf : extend the use of salt_EvPrRn & temp_EvPrRn (fresh-water
6022      tracer content) to linFS or no RealFreshWaterFlux ; default remains unchanged.
6023    o define mass2rUnit & rUnit2mass as units conversion factor, used for surface
6024      forcing. mass2rUnit: from mass per unit area [kg/m2] to r-coordinate unit
6025      (z-coord: =1/rhoConst ; p-coord: =gravity) ; rUnit2mass is just the reverse;
6026      and remove horiVertRatio (& recip_horiVertRatio). Affects truncation error
6027      of exp. global_oce_in_p: 10 16 16 14 16 13 16 16 16 13 13 13 16 13 13 12 16
6028      -> update output.txt
6029    o pkg/cd_code: add brackets in multiple terms sum (S/R CD_CODE_SCHEME):
6030     this affects truncation error: -> update output.txt of exp:
6031      global_ocean.90x40x15 (fw&adm), lab_sea (fw&adm) & lab_sea.lsr,
6032      ideal_2D_oce, isomip.htd, natl_box, tutorial_global_oce_latlon.
6033    
6034    checkpoint59f (2007/08/21)
6035    o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode)
6036    o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in
6037      a bounded range (in forward mode)
6038    o pkg/ecco, ctrl, autodiff and mom_common:
6039     internal parameter controls, completements of implementations
6040    o add few EXCH S/R (UV_BGRID, UV_DGRID, SM) for B & D-Grid velocity & 2nd Moment Sxy.
6041    o use UV_BGRID exch for dxV,dyU: for now, only with pkg/exch2 & forward ;
6042      (not seem any difference in testing results).
6043    o pkg/cd_code: use the right EXCH calls (for CS-grid); but problem remains
6044       at face corners.
6045    o pkg/generic_advdiff:
6046     - in GAD.h, define as parameters (iMinAdvR,iMaxAdvR,jMinAdvR,jMaxAdvR)
6047      loop range indices for computing vertical advection tendency
6048      and do the calculation in the interior only (no overlap) ;
6049      for now, only implemented for SOM advection (to save CPU time).
6050     - add argument "withSigns" to S/R FILL_CS_CORNER_TR_RL (needed for SOM_xy moment)
6051    o exch2 adjoint
6052      First set of changes:
6053      - add exch2 hand-written adjoint templates
6054      - exch2 hand-written no longer use TAF-flag 'nownew_arg'
6055        This will require cleanup in pkg/autodiff/*.F
6056        (changed routines currently kept separate in verif. code/)
6057      - Comment all relevant #ifndef ALLOW_AUTODIFF_TAMC
6058        that used to hide exch2 or cubed-sphere specific code
6059        (commented via 'cph-exch2')
6060    o pkg/seaice
6061      - Close southern and western boundaries for UICE/VICE when useOBCS=.TRUE.
6062    o pkg/bulk_force: fix loading into Qsw of Short-Wave flux; and update
6063       output of global_ocean.cs32x15.thsice .
6064    
6065    checkpoint59e (2007/07/26)
6066    o exch2: new S/R that only use the cube-tracer (center-position) exchange:
6067      for B-grid vector (not yet tested) and C-grid vector (<- only used
6068      when option W2_USE_R1_ONLY in W2_OPTIONS.h is defined).
6069    o starting implementation of Duffy et al. (GRL 1999) salt plume scheme
6070      (#ifdef ALLOW_SALT_PLUME)
6071    o gather_2d/scatter_2d: removed halo regions
6072    o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
6073      scheme and the corresponding test case (under front_relax dir). For now,
6074      only available with Skew-flux form and not yet tested in realistic set-up.
6075      adjoint: store directives updated, but gradient checks deteriorated,
6076      so maybe GM/Redi adjoint is now broken.
6077    o seaice adjoint
6078      * add AREA, HEFF, HSNOW as control variable
6079        (should not change lab_sea results)
6080      * CTRL_OPTIONS.h needs new flag: CTRL_SET_OLD_MAXCVARS_40
6081    o pkg/seaice:
6082      * added computation of saltFlux in seaice_growth;
6083        For time being, sea ice salinity is assumed constant
6084        contribution of snow flooding to freshening of sea ice is neglected.
6085        SEAICE_salinity is set in SEAICE_PARM01 of data.seaice and it
6086        defaults to 0.0 in order to maintain backward compatibility.
6087        Typical values for SEAICE_salinity are 4 to 10 g/kg.
6088      * replaced dRf(1) with dRf(kSurface)*hFacC(kSurface) in seaice_growth.F
6089      * added SEAICE_availHeatFrac, which specifies fraction of surface level
6090        heat content used to melt or grow ice
6091      * commented out cap of HICE: it helps keep ice thinner
6092      * reintroduced cap of HEFF via MAX_HEFF and SEAICE_CAP_HEFF option
6093      * applied OBCS T/S mask to HEFFM sea ice mask
6094    
6095    checkpoint59d (2007/06/21)
6096    o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
6097     for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
6098     (keep {PKG}_DIAGNOSTICS_FILL for non-state variables diagnostics)
6099    o pkg/gmredi (gmredi_readparms.F): add some missing "_d 0"
6100     and change default value of parameter "GM_Small_Number";
6101     update output of exp: lab_sea (x2), cfc_example, global_ocean.90x40x15,
6102       global_ocean.cs32x15 (x4), global_ocean_ebm, global_with_exf,  
6103       tutorial_global_oce_biogeo, tutorial_global_oce_latlon
6104    o pkg/ecco: cost function when applying pkg/smooth to controls
6105    o pkg/ctrl: add forcingPrecond run time parameter
6106    o pkg/seaice:
6107     - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code
6108     - fix bug in metric terms of u-equation in LSR solver (implicit part),
6109       changes verification/lab_sea
6110     - rearrange implicit part of u-equation in LSR solver to make it easier to
6111       read, understand, and debug. This causes changes at the truncation level.
6112     - fix (serious) bug in the boundary conditions (sign error in the implicit
6113       part) of the LSR solver. Changes all LSR results.
6114     - fixed problem with HSNOW initialization to avoid thick snow when AREA
6115       is initilized with small values - does not change lab_sea results.
6116     - added HsnowFile initialization capability
6117    o pkg/smooth: addition to model/src and pkg/ctrl so allow
6118     initialization of pkg/smooth and application to control vector
6119    o pkg/seaice: fix another bug in the LSR no-slip boundary conditons
6120    o dependencies: pkg/profiles requires pkg/cal
6121    o pkg/profiles:
6122     - added option ALLOW_PROFILES_GENERICGRID
6123         -> pkg/profiles can thus be used with any grid (e.g. cs32x15) assuming
6124         that interpolation information (grid points and coefficients) is provided
6125         within the netcdf input files.
6126         -> sample matlab scripts can be found in MITgcm_contrib/gael
6127         that allow you to prepare netcdf input files.
6128     - also modified: cleaner include statements, cleaner error print statements,
6129       cleaner stops when error, and more tests of the netcdf input files consistency.
6130    o additional test (in global_ocean.cs32x15) using seaice+thsice pkgs.
6131    o pkg/seaice:
6132     - move seaice-diagnostics from seaice_do_diags to do_statevars_diags; this
6133       requires a new routine: seaice_diagnostics_fill.F
6134     - make sure that seaice does not move if not forced (pressure replacement
6135       method, Hibler and Ip, 1995), changes results
6136     - and new damping criterion for EVP solver according to Hunke, JCP, 2001
6137     - SEAICE_evpDampC = > 0. turns it on (615. is the recommended value).
6138       It is turned off by default (=-1.), because it changes the results.
6139     - make it possible to read AREA from a file, too.
6140    
6141    checkpoint59c (2007/06/04)
6142    o add S/R and diagnostics for oceanic mixed-layer depth
6143    o move GMRedi call after all vertical mixing schemes (including KPP)
6144    o pkg/thsice:
6145     - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
6146      (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
6147    o pkg/obcs:
6148     - bug fix for balance code
6149    o pkg/seaice:
6150      - allow values of SEAICE_elasticParm > 1
6151      - add new parameter SEAICE_evpTauRelax as an alternative
6152        to SEAICE_elasticParm
6153      - make lsr boundary conditions free slip (by default), changes result
6154      - add code for no slip boundary conditions for lsr
6155      - set minimum of zeta to zero (and not 4e8) (changes results)
6156      - add a cap on AREA after advecting AREA if seaice_growth is not called
6157    o change calculation of Visbeck K:
6158      - no longer depend on tapering scheme; instead, compute slope (limited
6159        by GM_maxSlope). this is equivalent to what was comuted before with
6160        clipping or linear tappering.
6161      - fix vertical averaging (wrong by 1/2 level)
6162      - leave the old version (but will not be maintained) within
6163        #ifdef OLD_VISBECK_CALC / #endif
6164      - update output of exp. ideal_2D_oce
6165    o change error catch in calc_r_star to improve vectorization
6166    o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and
6167      add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
6168    o adjoint:
6169      Re-organized adjoint checkpointing according to Matt Mazloff
6170      (but with modifs/completions/cleanups)
6171      Storing is now bundled into large arrays to optimized I/O
6172      (and second step in cleanup of the_main_loop)
6173    
6174    checkpoint59b (2007/05/16)
6175    o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
6176      - export/import (between ocean & coupler) fields needed for ocean DIC.
6177    o pkg/seaice:
6178      - get rid of three more exchanges seaice_calc_viscosities (required
6179        different loop boundaries in seaice_lsr and seaice_ocean_stress)
6180      - bug fix in seaice_ocean_stress (update of lab_sea required)
6181      - reduce loop boundaries to necessary minimum also in seaice_evp
6182      - go back to the old way of computing deltaC/Z as the adjoint likes that
6183        better
6184    o Refresh of tutorial_global_oce_latlon (includes changing salinity-like
6185      passive tracer to an Age Tracer) + update output.txt
6186    o pkg/exf:
6187      - implement A-grid / C-grid selection for wind-stress input files.
6188      - clean-up exf_wind.F (remove us, use wspeed instead ; add wStress)
6189      for now, in exf_bulk_largeyeager04.F only :
6190      - change implementation for case where windspeed + 2. components wind-stress
6191        are read-in. AND use rhoConstFresh to convert evap.
6192    o pkg/seaice:
6193      - use correct EXCH_UV for wind-forcing (on A-grid).
6194      - change SEAICE_OPTIONS.h to limit the number of option combinations (regarding
6195        SEAICE_EXTERNAL_FORCING & SEAICE_EXTERNAL_FLUXES); add corresponding stops.
6196    o pkg/exf:
6197      - default EXF options are now set in EXF_OPTIONS.h (ifndef ALLOW_AUTODIFF_TAMC)
6198      EXF_INTERPOLATION:
6199      - merge global_with_exf/code version of exf_interp_read.F
6200        to the main code ;
6201      - Add new option: EXF_INTERP_USE_DYNALLOC to use Dynamical Allocation when
6202        reading the file ; Important: This options needs to be defined to recover
6203        previous code.
6204        otherwise, use fixed size array to read in (size=exf_interp_bufferSize).
6205      - no longer loose real*8 precision along the way when using exf_iprec=64.
6206  o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)  o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
6207      - change discretisation of evp-solver in order to avoid another exchange
6208        (changes lab_sea) and clean up a little
6209      - replace SQRT(MAX(deltaC,SEAICE_EPS)) by MAX(SQRT(deltaC),SEAICE_EPS)
6210        help the adjoint (this also changes the results slightly)
6211      - add a few "_d 0" where they had been missing in seaice_evp.F
6212      - cleaning up: remove unused seaice_calc_rhs.F
