5      ==============================      ==============================
6    
7    o pkg/seaice: add the option to prescribe a fixed thickness PDF
8      for thermodynamic calculations
9      - because of divisions of the type 7/7 not exactly equal to 1, this change
10        affects results of some verification experiments by up to 4 digits:
11        global_ocean.cs32x15.seaice, lab_sea, lab_sea.fd, lab_sea.salt_plume,
12        seaice_obcs, seaice_obcs.seaiceSponge, seaice_obcs.tides
13        adjoint: lab_sea, lab_sea.noseaicedyn
14        -> updated
15    
16    checkpoint65i (2015/01/23)
17    o model/src:
18      - change units of frictionHeating field from W to W/m^2
19      - fix bug in frictional heating from stratospheric drag in
20        S/R ATM_PHYS_TENDENCY_APPLY_V
21      - with synchronous time-stepping: move resetting to zero of frictionHeating
22        field from load_fields_driver.F to thermodynamics.F ;
23      - add diagnostics for frictional heating.
24    o model/src & gmredi K3D:
25      - add frictionHeating field to pickup-files (for synchronous time-stepping)
26      - move ALLOW_EDDYPSI block out of DYNVARS.h and merge it into FFIELDS.h
27      - rename uMean,vMean --> uEulerMean,vEulerMean (+ change diagnostics name
28        and name in pickup file).
29      - fix arguments of few DIAGNOSTICS_FILL calls in gmredi_k3d.F
30    o model/src:
31      - move (from ini_forcing.F) initialisation of all arrays in header file
32        FFIELDS.h into new S/R ini_ffields.F ; this fix broken restart
33        (since Nov 2012) with option selectAddFluid=1.
34    o pkg/shelfice:
35      - change units (+ document) of newly added field "shelfIceMassDynTendency"
36      - upgrade from _RS to _RL shelficeMass & shelficeLoadAnomaly arrays.
37    o pkg/obcs: re-organize obcs_calc_stevens.F to prepare for passive tracers
38    o pkg/seaice: two new runtime parameters:
39      - SEAICE_cStar replaces the hard wired "20" in the strength formulation,
40        long overdue
41      - SEAICE_tensilFac: preparation for Koenig-Beatty+Holland (2012)
42        parameterization of tensil stress for fast ice (does not do anything yet)
43    o pkg/seaice/seaice_check.F: left over from restricted addtive Schwarz method
44        for LSR: move checking overlaps out of JFNK-if-block
45    o pkg/atm_phys:
46      - move copy of grid and dynamical fields out of atm_phys_driver.F into
47        new S/R ATM_PHYS_DYN2PHYS.
48      - fix level height for Linear Free-Surf case (to be consistent with
49        fixed-in-time pressure levels).
50    o pkg/mom_common (bottomdrag):
51      - average bottomDragFld (ALLOW_BOTTOMDRAG_CONTROL) from grid-cell center
52        to correct location (U & V point) in S/R MOM_U/V_BOTTOMDRAG;
53        update output (adm & tlm) of experiment global_ocean.90x40x15.bottomdrag.
54    o pkg/shelfice (u/v_drag):
55      - add one argument (the other velocity component) to S/R SHELFICE_U/V_DRAG;
56      - use SHELFICEDragLinear & SHELFICEDragQuadratic in shelfice_v_drag.F
57        (now similar to shelfice_u_drag.F)
58      - remove condition on bottomDragTerms when calling SHELFICE_U/V_DRAG
59        from mom_vecinv.F (similar to mom_fluxform calls).
60    o pkg/mom_common (bottomdrag):
61      - add one argument (the other velocity component) to S/R MOM_U/V_BOTTOMDRAG;
62      - add options for alternative discretisation of velocity norm in quadratic
63        bottom drag: averaging of grid-cell-center KE to U.point and V.point
64        (selectBotDragQuadr=0, original code) can produce noisy patterns; this
65        improves when averaging only the other component (e.g. vVel for U bottom
66        drag) using wet-point method (selectBotDragQuadr=2) or not (=1).
67      - add options (bottomVisc_pCell) to account for partial-cell in bottom
68        friction (no-slip BC) thus getting the true distance from the bottom;
69        off by default since this also reduces model stability (explicit bottom
70        friction). Changes produce different machine truncation with linear-drag
71        + no-slip BC: update output of experiments exp4.stevens (10 digits) and
72        front_relax (bvp & mxl, 10 & 11 digits).
73    o model/src & mom pkgs:
74      - add one more level to vertical viscosity local arrays (Nr+1, previously Nr)
75        since no-slip bottom BC uses viscosity @ k+1 to update velocity @ level k
76      - for now and until vertical mixing scheme are updated to fill up level Nr+1,
77        just copy level Nr value to level Nr+1.
78    o doc:
79      - add notes form Abhisek Chakraborty on how to close Heat & Salt budgets.
80    o pkg/streamice:
81      - shelfice_init_varia.F, shelfice_init_fixed.F, shelfice_readparms.F,
82        SHELFICE.h: move array shelficemass to init_varia, initialise
83        from array shelficemassinit, which is set in init_fixed and
84        has option to be set from file; introduce array
85        shelficeMassDynTend array, set thru file in init_fixed
86      - NEW FILE: shelfice_step_icemass.F: update shelficemass from either
87        shelfIceFreshWaterFlux and shelficeMassDynTend or H_streamice in
88        pkg/streamice
89      - shelfice_thermodynamics.F: call shelfice_step_icemass if
90        SHELFICEMassStepping = .true.
91      - shelfice_ad_diff.list: add new subroutine shelfice_step_icemass.f
92    
93    checkpoint65h (2014/12/17)
94    o verification/global_ocean.90x40x15, global_ocean_ebm:
95      - update to generic controls.
96    o pkg/ctrl:
97      - ctrl_map_ini_genarr.F: test for igen>0
98      - ctrl_init_variables.F: add call to CTRL_MAP_INI_GENTIM2D.
99      - move gentim2d part of ctrl_map_ini_genarr.F to
100        new separate routine : ctrl_map_ini_gentim2d.F
101      - ctrl_cost_driver.F,ctrl_init.F ctrl_map_ini_genarr.F:
102        add time variable weights and cyclic controls (time mean,
103        seasonal cycle, etc) capabilities to gentim2d
104    o pkg/ecco:
105      - move reading of error, conversion to weights from
106        ecco_cost_init_fixed.F to ecco_toolbox.F (ecco_readwei)
107    o global_oce_llc90, cs32:
108      - activte sbo.
109      - CTRL_SIZE.h : add maxCtrlProc.
110      - activate the new genctrl capabilities.
111      - update following reorganization of global_oce_input_fields.tar.gz  
112    o pkg/ctrl/ctrl_ad_diff.list:
113      - add missing ctrl_init_rec.f
114    o tools/OAD_support/keepOriginal:
115      - add ctrl_init_rec.F
116    o model/src/the_main_loop.F, pkg/ctrl/ctrl_map_ini_genarr.F:
117      - avoid recomputations of xx_gentim2d_dummy.
118    o momentum diagnostics:
119      - move filling of diagnostics Um_Diss & Vm_Diss from mom_fluxform.F and
120        mom_vecinv.F to timestep.F (to include Smag-3D contribution).
121    o pkg/seaice/seaice_lsr.F:
122      - fix computation of BU/BV, make sure they are non-zero, only necessary
123        for cubed sphere exchanges and SEAICE_OLx/y>0.
124        This makes calling s/r fill_cs_corner_rl obsolete (removed).
125    o verification/global_ocean.cs32x15/input.seaice
126      - add test for strong implicit coupling and restricted addtive Schwarz
127        methods for LSR
128      - update results/output.seaice.txt
129    o verification/tutorial_global_oce_biogeo:
130      - AD & OAD set-up: switch off ALLOW_OLD_VIRTUALFLUX (like in fwd set-up)
131        and set PTRACERS_EvPrRn(1,2) to zero (for DIC & ALK);
132        update output_adm,_oadm,_tlm.txt
133    o pkg/dic:
134      - change default to "#undef ALLOW_OLD_VIRTUALFLUX" in DIC_OPTIONS.h
135      - add a stop when ALLOW_OLD_VIRTUALFLUX is defined and PTRACERS_EvPrRn
136        for tracer 1 & 2 is set (to avoid double counting of dilution effect).
137    o verification/tutorial_global_oce_biogeo:
138      - AD & OAD set-up: do not set PTRACERS_EvPrRn for tracer 1 & 2 since
139        dilution is already added by pkg/dic ALLOW_OLD_VIRTUALFLUX ;
140        update output_adm,_oadm,_tlm.txt
141    o eesupp/src:
142      - add fill_cs_corner_rl.F (_RL-copy of fill_cs_corner_rs.F)
143        and call it in seaice_lsr when using nonzero SEAICE_OLx/y
144    o pkg/seaice: introduce strongly implicit coupling, intended for stabilizing
145      LSR (following Hutchings et al. 2004)
146      - introduce zetaZ as a global variable (requires adjustments in
147        seaice_evp.F and seaice_jfnk.F) and compute analoguously to etaZ
148        in seaice_calc_viscosities.F
149      - new flag SEAICEuseStrImpCpl (default off)
150      - add new terms zetaZ*du/dy and zetaZ*dv/dx on both sides of the
151        momentum equations
152      - JFNK-solver (preconditioner) adjusted to allow using this method
153        (where it does not have any positive effect)
154    o pkg/seaice
155      - add overlap for restrictive additive Schwartz method also to LSR, but
156        turn it off by default (because it only seems to work for non-cubed
157        sphere/llc topologies)
158    o pkg/autodiff
159      - add extra exchanges in addummy_in_steppging also for mnc output
160    o pkg/seaice:
161      - add extra exchanges before dumping adjoint fields in seaice_ad_dump.F
162        to avoid stripes in the adjoint output (similar to addummy_in_stepping.F)
163    o pkg/obcs:
164      - add option to specify domain-connected piece Id along OB though files
165        (for now, only used to diagnose PhiVel; default =1 -> global correction)
166      - modify obcs_diag_balance.F to process each connected-part separately;
167        exclude OB where Id = 0 but keep the full divergence there (-> constant
168        Psi along this portion of OB and all inflow derived from grad(Phi))
169      - add example of OB-conect files in verification/so_box_biogeo/input.
170    o pkg/diagnostics:
171      - improve treatment of Open-Boundaries in Velocity-Potential calculation:
172      a) use non zero matrix element across OB and solve for Phi 1 grid point
173         outside OB (i.e, where tracer OBCS are applied).
174      b) global imbalance of inFlow/outFlow across OB: instead of modifying
175         velocity across OB, spread it uniformly along the OB in the RHS.
176    
177    checkpoint65g (2014/11/19)
178    o pkg/diagnostcis:
179      - add preconditioner off-diagonal factor (diagCG_pcOffDFac) as run-time param
180    o pkg/my82,pp81,kl10:
181      - fix ALLOW_3D_DIFFKR implementation (previously had no effect): use 3-D
182        field diffKr as background diffusivity to set minimum diffusivity value.
183    o pkg/seaice:
184      - add new parameter SEAICEuseEVPrev (for revisited EVP by
185        Bouillon et al 2013)
186      - add SEAICE_evpAlpha/Beta to namelist
187      - modify seaice_evp code to able to use SEAICEuseEVPrev. These changes
188        involve trivial re-ordering of divisions/multiplications that should not
189        have any effects, but ... they do change the results of lab_sea.hb87 so
190        that only 2 digits of agreement remain, in line with the general
191        instability/fragility of the evp-code. For now, I do not care and just
192        update the verification experiment
193    o pkg/ctrl : add generic pre-processing (xx_genarr2d_preproc etc)
194      - remove xx_genarr2d_numsmooth etc
195      - use xx_genarr2d_preproc etc instead
196      - carry out smooth_correl2D at initialization stage rather than during
197        time stepping.
198      - get smoothOpNb from xx_gentim2d_preproc
199    o global_oce_cs32 :
200      - add test of generic ecco capabilities.
201    o pkg/exf/exf_getsurfacefluxes.F :
202      - add to tmpUE/tmpVN rather than re-initializing them (conventional behavior).
203    o pkg/ctrl,ecco :
204      - omit un-necessary arguments to ctrl_cost_gen.F unless ECCO_CTRL_DEPRECATED
205        is defined.
206    o pkg/seaice: add diagnostics for Delta (deformation parameter)
207    o model/src:
208      - when ALLOW_3D_DIFFKR is defined, add a Warning if any of the vertical
209        diffusivity (background) is specified but ignored.
210    o verification:
211      - in testreport, convert hostname to lower case for default output dir name
212    o model, pkg : add useCTRL, useECCO parameters (on/off run time switch).
213    o pkg/dic: add modifications from Hajoon:
214      - add iron sedimentation flux function of the flux of PO4 out of bottom layer
215      - light attenuation: add self-shading effect by climatological Chlorophyll
216        (read from file).
217    o pkg/seaice/seaice_preconditioner.F : fix cpp flags, so that code also
218        compiles when SEAICE_ALLOW_DYNAMICS is undefined
219    o global_oce_llc90,cs32 : ecco_v4 verification exps now use separate
220        AUTODIFF_OPTIONS.h, CTRL_OPTIONS.h, ECCO_OPTIONS.h rather than
221        ECCO_CPPOPTIONS.h (i.e. replacing the deprecated, circumvoluted,
222        approach where CPP_OPTIONS.h includes an omnipotent
223        ECCO_CPPOPTIONS.h that superseeds pkgs '_OPTIONS.h').
224    o pkg/ctrl/ctrl_map_ini_genarr.F : include GMREDI_OPTIONS.h where
225        ALLOW_3D_KAPGM, ALLOW_3D_KAPREDI (to be added later) belong.
226    o pkg/seaice/SEAICE_SIZE.h : replace ALLOW_AUTODIFF_TAMC with ALLOW_AUTODIFF
227        to avoid needing AUTODIFF_OPTIONS.h anytime SEAICE_SIZE.h is included
228        (it seems that THSICE_SIZE.h, PTRACERS_SIZE.h have the same issue...)
229    o model/src, pkg/smooth, profiles, salt_plume, seaice, exf, ecco, ctrl :
230      add ECCO_OPTIONS.h, AUTODIFF_OPTIONS.h, CTRL_OPTIONS.h when needed
231      - ECCO_OPTIONS.h is needed when including ecco_cost.h, ecco.h
232      - AUTODIFF_OPTIONS.h is needed when including tamc.h, tamc_keys.h
233      - CTRL_OPTIONS.h is needed when including ctrl.h, optim.h, etc
234    o pkg/ctrl,ecco,exf :
235      - remove variables associated with NON-generic costs,
236        unless ECCO_CTRL_DEPRECATED is defined.
237      - remove NON-generic NON-obcs controls,
238        unless ECCO_CTRL_DEPRECATED is defined.
239    o pkg/ctrl : added ctrl_local_params.h
240    o pkg/ecco : added ecco_local_params.h
241    o verification : added ECCO_CTRL_DEPRECATED to most as and oad
242        experiments, which will progressively be removed once the
243        experiments are revised to use only generic controls/costs.
244    
245    checkpoint65f (2014/10/13)
246    o pkg/ctrl, ecco, seaice : minor changes in headers
247    o global_oce_llc90,cs32 : ecco_v4 verification exps now test generic
248        cost function and control capabilities added since checkpoint65c.
249    o pkg/ctrl: regroup all obcs ctrl variables in CTRL_OBCS.h.
250    o pkg/ecco: increase modularity and improve logic
251      - ecco_toolbox.F (new) : basic operations that are often used,
252        including ecco_zero, ecco_cp, ecco_cprsrl, ecco_diffmsk,
253        ecco_addcost, ecco_add, ecco_div, ecco_readbar.
254      - cost_gencal.F (new) : determine filnames and records.
255      - cost_genread.F, cost_generic.F : condense code using ecco_toolbox.
256      - cost_generic.F : use spzeroloc rather than hard-coded -9999,
257        and exploit the above functions leading to more compact code.
258      - cost_genread.F : rm un-necessary arguments, re-arrange args order.
259      - ecco_check.F, ecco_readparms.F : bring logic up to date (using_tpj,
260        using_ers, using_gfo, using_mdt is now only defined within gencost)
261    o pkg/ecco: extend generic cost capabilities
262      - pkg/ecco : added 3D gencost (ALLOW_GENCOST3D), added gencost
263        capabilities via gencost_preproc (+ _c,_i,_r related params),
264        gencost_posproc (+ _c,_i,_r related params), gencost_nrecperiod,
265        gencost_outputlevel arguments to cost_generic
266      - pkg/ecco/cost_genread.F (new) : interface between cost_generic
267        and active_read, making room for gencost_preproc to take effect.
268        Added preproc code ('climmon') to replace GENERIC_BAR_MONTH.
269      - pkg/ecco/cost_generic.F :
270        compute and store misfit maks*(model-data) in localdif that is
271        then used in cost and for output, output misfit if outlev.GT.0
272      - pkg/ecco/cost_averagesfields.F : depend on gencost_barskip
273        rather gencost_barfile for deciding whether to write barfile
274      - pkg/ecco/ecco_cost_driver.F : extract call to cost_profiles from cost_hyd
275      - pkg/ecco/ecco_cost_init_fixed.F : extract gencost weights from
276        ecco_cost_weights, re-activate ecco_summary, determine gencost_barskip
277      - pkg/ecco/ecco_summary.F : report gencost variables
278      - pkg/ecco/cost_gencost_customize.F : treat case of scatterometer costs
279    o pkg/sea/SEAICE_OPTIONS.h : add ALLOW_COST_ICE, ALLOW_SEAICE_COST_SMR_AREA
280    o pkg/ecco: internal re-organization
281      - resolve un-necessary dependancies within pkg/ecco and to pkg/ctrl
282        (rm includes of optim.h and ctrl.h, replace optimcycle with eccoiter,
283        mv relevant variables definition from ecco_cost.h to ecco.h,
284        make sure gencost routines only include ecco.h)
285      - throughout : add missing CCP switches, rm unused variables,
286        and rm un-necessary CPP switches
287      - throughout gencost routines : replace modelstartdate with
288        gencost_startdate when needed
289      - cost_bp_read.F : use arguments, instead of common blocs
290        so that it can be used also by (new) cost_gencost_bpv4.F
291      - ecco_init_varia.F : initialize RHOsumGlob_0, VOLsumGlob_0
292      - ecco_phys.F : compute etanFull
293      - ecco_readparms.F : rename using_topex as using_tpj, add
294        bpv4-grace to gencost list, initialize added parameters
295      - ecco_summary.F : include SIZE.h needed for augmented ecco.h
296    
297    checkpoint65e (2014/09/28)
298    o pkg/obcs:
299      - replaced the just-added CPP options with run-time variables
300        (see pkg/obcs/OBCS_PARAMS.h for details)
301    o pkg/obcs:
302      - add additional CPP options for sponge boundary layers
303        (see pkg/obcs/OBCS_OPTIONS.h for details)
304    o pkg/atm_phys:
305      - implement simple (obliquity only, assuming circular planet orbit)
306        seasonal cycle for incoming insolation ; used when run-time parameter
307        "select_incSW" is set to 1 ; by default (=0), uses old unchanged formula.
308    o pkg/exf, pkg/ecco, pkg/ctrl:
309      - add ctrlUseGen and .NOT.ctrlUseGen exclusive brackets
310      - activate gentim2d for xx_atemp,xx_aqh,xx_swdown,xx_lwdown,xx_precip

317        verification/hs94.1x64x5/code_oad/ctrl_map_gentim2d.F :
318      - add weight in CTRL_GET_GEN calls
319    o pkg/ctrl :
320      - ctrl_get_gen.F : add weight as input parameter, and apply
321        it directly rather than using smooth_correl2Dw (to be retired).
322      - ctrl_map_gentim2d.F : add wgentim2d in CTRL_GET_GEN call
323    o pkg/ctrl :
324      - introduce run time switch ctrlUseGen (in ctrl.h, ctrl_check.F,
325        ctrl_init_variables.F, ctrl_readparms.F, ctrl_summary.F)
326      - re-activate ctrl_summary (call in ctrl_init.F)

334    
335    checkpoint65d (2014/09/15)
336    o pkg/ctrl/CTRL_GENARR.h, ctrl_readparms.F :
337      - add xx_genarr2d_bounds,xx_genarr3d_bounds,
338        xx_genarr2d_numsmooth, xx_genarr3d_numsmooth
339    o pkg/ctrl/ctrl_map_ini_genarr.F :
340      - remove compilation failure
341      - replace hard coded example
342      - use ctrl_map_ini_gen2D, 3D
343    o pkg/ctrl/ctrl_pack.F, ctrl_unpack.F :
344      - on/off switch based upon xx_genarr2d_weight,3d
345    o src/packages_init_variables.F :
346      - regroup pkg/estimation calls
347      - remove CTRL_MAP_INI, CTRL_MAP_INI_ECCO
348        (moved to ctrl_init_variables)
349    o cost/cost_init_varia.F :
350      - remove ecco_cost_init_varia
351        (moved to ecco_init_varia)
352    o ctrl/ctrl_init_variables.F :
353      - add CTRL_MAP_INI, CTRL_MAP_INI_ECCO
354      - add CTRL_MAP_INI_GENARR, SEAICE_CTRL_MAP_INI
355    o ctrl/ctrl_map_ini.F :
356      - remove ctrl_map_ini_genarr, seaice_ctrl_map_ini
357        (moved to ctrl_init_variables)
358    o ctrl/ctrl_map_ini_ecco.F :
359      - remove ECCO_PHYS (mv to ecco_init_varia)
360      - remove seaice_ctrl_map_ini (mv to ctrl_init_variables)
361    o ecco/ecco_ad_diff.list :
362      - add ecco_init_varia.f
363    o ecco/ecco_init_varia.F
364      - new routine
365    o pkg/streamice:
366      - move call to STREAMICE_INITIALIZE_PETSC from the_model_main.F
367        to streamice_init_fixed.F ; fix setting of STREAMICEisOn.
368      - from model/src, only call pkg/streamice routines if useStreamIce is TRUE.
369    o pkg/generic_advdiff:
370      - fix bug causing negatives in GAD_SMOLARKIEWICZ_HACK, introduced 8/8/2014.
371    o pkg/exf:
372      - exf_getffields.F : add xxg_atemp, xxg_aqh, xxg_swdown, xxg_lwdown,
373         xxg_precip capability
374      - exf_wind.F : no need for ALLOW_WSPEED_CONTROL cpp switch
375    o pkg/ctrl:
376      - ctrl_pack.F, ctrl_unpack.F : omit (un)packing of undefined xx_gentim2d
377    o model/src/load_fields_driver.F :
378      - move call to CTRL_MAP_GENTIM2D ahead of BULKF_FIELDS_LOAD, EXF_GETFORCING
379        so xx_gentim2d can be applied to e.g. exf fields in a timely manner.
380    o OpenAD verification experiments:
381      - Include explicitly AUTODIFF_OPTIONS.h, COST_OPTIONS.h, and CTRL_OPTIONS.h
382        in src files (to enable to skip the ECCO_CPPOPTIONS.h);
383        for now, only in pkgs used in OpenAD verification experiments.
384      - Change all except one (halfpipe_streamice) OpenAD experiments to use pkg
385        specific option file (AUTODIFF_OPTIONS.h, COST_OPTIONS.h & CTRL_OPTIONS.h)
386        instead of using ECCO_CPPOPTIONS.h (with all relevant options in it).
387        This applies to both TAF (*/code_ad/) and OpenAD (*/code_oad/) tests.
388    o OpenAD verification tests:
389      - finish removing ALLOW_AUTODIFF_OPENAD (replaced by ALLOW_OPENAD);
390      - finish replacing ALLOW_AUTODIFF_TAMC by ALLOW_AUTODIFF (except for
391        tape/storage which are specific to TAF/TAMC) in pkgs used in OpenAD exp.
392      - leave ALLOW_AUTODIFF_TAMC undef in OpenAD verification tests (*/code_oad/)
393        and remove local copy of "tamc.h" (needed only if ALLOW_AUTODIFF_TAMC).
394    o model/src & generic_advdiff:
395      - change hard-coded loop-range in S/R APPLY_FORCING_T/S to set T & S
396        forcing over 0:sNx+1, 0:sNy=1 (instead of just 1:sNx,1:sNy): Model
397        dynamics requires valid tracer forcing only over tile interior but, for
398        some diagnostics, may need to extend it over 1 point in tile halo region.
399      - in gad_calc_rhs.F, update calls to gmredi_x/ytransport to get valid
400        tendency over i,j_Min,Max range. This allows to simplfy i,j_Min,Max
401        setting in temp/salt/ptracer_integrate.F
402    o pkg/dic:
403      - multiply tracer tendencies by maskInC (if ussing OBCS) before updating
404        gchem tracers: this allows to skip the 2nd call to OBCS_APPLY_PTRACER
405        in gchem_forcing_sep.F
406    o pkg/autodiff & obcs:
407      - add storage of current OB values for U & V (was already done for T & S).
408    
409    checkpoint65c (2014/08/30)
410    o pkg/dic:
411      - take out of dic_atmos.F the initialisation part (corresponding to istate=0)
412        and move it to new S/R DIC_INI_ATMOS ; also simplify the dependencies for
413        AD compilers (but still a Pb with multi-threading and Ajoint dependencies).
414    o verification:
415      - new experiment testing OBCS and DIC pkgs, using params & output from
416        tutorial_global_oce_biogeo but limited to a sub-domain around Drake
417        passage: take OBCS from the last year of a 2 yrs simulation and initial
418        conditions from t=1.yr while keeping the same forcing.
419    o model/src:
420      - when allowFreezing=T, only reset below freezing initial Temp to Tfreezing
421        (at any k) if checkIniTemp is not set to FALSE (default checkIniTemp=T).
422    o pkg/diagnostics (Stats-Diags):
423      - re-write S/R DIAGSTATS_CALC (more similar to TARGET_NEC_SX part) to:
424        a) refine region where stats are computed, excluding where arrhFac=0 ;
425        b) fix missing interior mask (use with OBCS) in 3-D fields statistics;
426        c) extend regional stats over the region edges (for U or V pt location).
427    o pkg/gchem:
428      - add a (2nd) call to OBCS_APPLY_PTRACER in gchem_forcing_sep.F (needed since
429        pkg/dic is currently changing/updating ptracers values beyond the OB).
430    o verification (hs94):
431      - convert Held & Suarez external_forcing.F (from hs94.cs, with Sigma-coords
432        bits) to apply_forcing.F and undef USE_OLD_EXTERNAL_FORCING in experiments
433        hs94.cs-32x32x5 and tutorial_held_suarez_cs ; also use the same version of
434        apply_forcing.F in 2D hs94 (fwd, ad & oad) but keep LatLon hs94 unchanged.
435    o pkg/ptracers:
436      - implement Adams-Bashforth on pTracers (instead of on tracer tendency),
437        switched on by setting PTRACERS_doAB_onGpTr=F (default set to doAB_onGtGs)
438      - change exp4 secondary test (input.nlfs) to test AB on T & S & pTracer
439        with AB-2 code (so that it get tested).
440    o model/src:
441      - allow to apply Adams-Bashforth on Temp & Salt (instead of on gT,gS)
442        with AB-2 code (previously only available with AB-3 code).
443        Also move the code (call to ADAMS_BASHFORTH S/R) form thermodynamics.F
444        to temp/salt_integrate.F (since the 2nd part of gt/sNm1 update is done
445        there, by calling CYCLE_AB_TRACER).
446    o pkg/generic_advdiff:
447      - change Tracer argument (drop bi,bj indices) in S/R GAD_CALC_RHS,
448        GAD_C2_ADV_R, GAD_U3_ADV_R, GAD_C4_ADV_R, GAD_DIFF_R, GAD_BIHARM_R
449        + also in GMREDI_X/Y/RTRANSPORT ; and update corresponding calls in
450        S/R temp/salt/ptracers_integrate.F
451    o model/src & pkg/ptracers:
452      - remove common block variables gT,gS (in DYNVARS.h), except when
453         USE_OLD_EXTERNAL_FORCING is defined; update TAF storage accordingly.
454      - remove common block variable gPtr.
455    o model/src & pkgs:
456      - change gTracer (and/or tracer) argument (drop bi,bj indices) in S/R
457         ADAMS_BASHFORTH(2&3), CYCLE_(AB_)TRACER, FREESURF_RESCALE_G,
458         IMPLDIFF, SOLVE_TRIDIAGONAL & _PENTADIAGONAL, GAD_SOM_ADVECT,
459         GAD_ADVECTION, GAD_CALC_RHS, GAD_IMPLICIT_R, TIMEAVE_CUMUL_DIF_1T
460      + change accordingly all calling S/R.
461      - use local temperature/salinity/ptracer tendency array (without bi,bj)
462        in S/R temp/salt/ptracers_integrate.F
463    o pkg/seaice:
464      - move computation of stress contributions to rhsU/V in s/r seaice_lsr
465        to separate s/r seaice_lsr_rhsu/v in order to be able to re-use code
466      - make u/vIceC local variables if SEAICE_CGRID is defined only to be used
467        in seaice_lsr
468      - seaice_lsr.F: make local 4D arrays UXX, VYY, etc 2D
469        in s/r seaice_lsr_calc_coeffs
470    o pkg/mdsio:
471      - in MDS_READ/WRITE_FIELD, stop if file-name (+prefix) is too long
472        (e.g., > MAX_LEN_MBUF -90 ) or, in INI_MODEL_IO, if mdsioLocalDir is
473        too long (e.g., > MAX_LEN_FNAM/2 )
474    
475    checkpoint65b (2014/08/12)
476    o pkg/matrix:
477      - pass, as argument, updated tracer field to S/R MATRIX_STORE_TENDENCY_EXP
478    o model/src:
479      - fix initialisation of geothermalFile; compile geothermal-flux code in
480        natl_box verification experiment.
481    o model/src & pkg/down_slope:
482      - push the k loop inside S/R TIMESTEP_TRACER (now called outside the k loop).
483      - in dwnslp_apply.F, update tracer tendency instead of the future tracer
484        field and call S/R DWNSLP_APPLY before TIMESTEP_TRACER; this affects
485        results at machine truncation level: update output of experiments
486        global_ocean.90x40x15.dwnslp (FWD) and lab_sea.noseaicedyn (AD).
487    o pkg/diagnostics (Stats-Diags):
488      - do not cumulate the full volume when DIAGNOSTICS_FILL is
489        called with bibjFlg < 0 (no increment of the counter for 2D/3D diag);
490        This fix the mean statistics when DIAGNOSTICS_FILL is called multiple
491        times (but Min,Max and StD are still wrong).
492    o model/src:
493      - add geothermal flux forcing: read in ini_forcing.F as time-constant
494        field "geothermalFlux" applied in S/R APPLY_FORCING_T (apply_forcing.F)
495    o model/src:
496      - move CYCLE_TRACER calls from tracers_correction_step.F to temp/salt/ptracer
497        _integrate.F so that, when leaving S/R THERMODYANMICS, theta,salt and pTrac
498        arrays are already updated while adjustments (filters, conv.adjustment) are
499        still applied later, in S/R TRACERS_CORRECTION_STEP.
500    o model/src:
501      - store in common bloc array "rhoInSitu" the virtual potential temperature
502        anomaly that is used to compute geopotential: this make the atmos code
503        more similar to ocean code which already uses rhoInSitu in calc_phi_hyd.F
504    o pkg/seaice/seaice_lsr.F
505      - rename integer variable ilcall to ipass (that's what it is called
506        in the residual diagnostics
507      - change time stepping for NPSEUDOTIMESTEP > 2 (does not change the
508        default) for improved non-linear convergence of the first few steps
509      - adjust a few comments and add new ones to explain some of the store
510        directives
511    o pkg/generic_advdiff (& ptracers):
512      - re-work the code to check for valid advection scheme and for minimum
513        size of overlap (now stored in local common bloc in gad_advscheme.F)
514    o pkg/seaice: another attempt to make the adjoint work for sea ice dynamics
515      - re-initialize more variables in seaice_lsr: u/vIceC, u/vIceNm1
516      - add an auxilliary variable "bet" and fix store directives and keys in
517        seaice_lsr_tridiagu/v, this seems to do the trick (i.e. more or
518        less exact gradients in my tests); but there are still
519        recomputation warning (although gradients are sort of OK), when
520        SEAICE_LSR_VECTORIZE is not defined, so this flag and
521        SEAICE_LSR_VECTORIZE_ZEBRA are recommended for efficiency.
522      - update verification experiments lab_sea.
523      - change some comments in S/R seaice_calc_viscosities
524    o model/src:
525      - if staggerTimeStep=T, always apply exchange to velocity field in
526        do_stagger_fields_exchanges.F instead of in do_fields_blocking_exchanges.F
527        (independent of using multi-dim advection or not); no effect on FWD run
528        but affects AD results (at machine truncation level): update output of
529        experiment 1D_ocean_ice_column (ad: 12 digits), hs94.1x64x5 (ad,oad: 13.d)
530        and isomip (oad: 12.d).
531    o pkg/generic_advdiff:
532      - stop if doAB_onGtGs is set to FALSE but ignored
533      - refine warning related to stability of tracer time-stepping
534        regarding internal wave dynamics.
535      - setting of AdamsBashforth_T,S when doAB_onGtGs=F: remove condition
536        on staggerTimeStep & implicitIntGravWave (will now get a warning
537        if potentially unstable).
538    o pkg/kl10:
539      - add new pkg "kl10" for mixing due to internal wave breaking, from
540        http://www.sciencedirect.com/science/article/pii/S1463500310000144
541        (contribution from Jody Klymak), tested in verification experiment
542        verification/internal_wave/input.kl10/
543    o isomip experiment:
544      - test pkg/shelfice with Non-Lin Free-Surf in one of the FWD set-up
545        (input.htd) and update the output.
546    o cd_code experiments:
547      - use default cd_code options (#undef CD_CODE_NO_AB_MOMENTUM &
548        #undef CD_CODE_NO_AB_CORIOLIS) in experiments: cfc_example (fwd)
549        global_ocean.90x40x15 (ad & oad) and OpenAD (ad & oad) and
550        update the corresponding output.
551    o pkg/seaice:
552      - reduce the number of include files and store directives in
553        S/R seaice_lsr_tridiagu/v
554      - change the order of loops in one case in S/R seaice_lsr_tridiagv
555        (only for SEAICE_VECTORIZE_LSR_ZEBRA defined), which allows me to
556        get rid off one store directive (a TAF bug?)
557      - add one more instance of ifdef SEAICE_VECTORIZE_LSR_ZEBRA in
558        S/R seaice_lsr_tridiagv to change the loop range for consistency
559      - remove ilcall, m from parameter list of S/R seaice_lsr_tridiagu/v
560      - fix a bug that affects the JFNK solver: replace sNx/y by i/jMax in
561        S/R seaice_lsr_tridiagu/v (requires update of
562        offline_exf_seaice/input.dyn_jfnk)
563    
564    checkpoint65a (2014/07/27)
565    o model/src:
566      - Non-Lin Free-Surf in p/z coords: allows hFacW,S to be larger than
567        surrounding hFacC=1 @ edge of a step with different kSurfC on either side
568        (topo in p-coords, ice-shelf in z-coords); update output of experiments
569        tutorial_global_oce_in_p and isomip (both AD and OpenAD output).
570    o model/src:
571      - collect momentum forcing tendency into local 2-D array (passed as argument
572        to apply_forcing S/R); this simplifies mom. Forcing diagnostics and CD_CODE
573        parts in timestep.F (without CD_CODE_NO_AB_MOMENTUM defined = the default);
574        affects results at machine truncation level (e.g., if using OBCS_SPONGE).
575      - collect T & S forcing tendency into local 2-D array (passed as argument to
576        apply_forcing S/R); add 3-D diagnostics for temp & salt forcing tendency.
577        affects results at machine truncation level (e.g., ocean: if using
578        SHORTWAVE_HEATING ; atmos: if using FrictionHeating or (atm_Rq<>0) moist
579        correction due to vertical advection).
580      - update output of experiments: fizhi-cs-32x32x40 (13 digits),
581        global_ocean.cs32x15 (fwd: icedyn, seaice, thsice, all 3 @ 11d; adm & tml:
582        seaice_dynmix & thsice, fwd grd @ 3 & 8), hs94.1x64x5 (ad grd @ 13),
583        obcs_ctrl (ad & fwd grd @ 12 & 7).
584    o pkg/ptracers & diagnostics:
585      - use ptracers (short) name (instead of long one) to make ptracers diagnostics
586        title (to avoid some unexpected truncation); sort out ptracers diags units.
587      - collect ptracer forcing tendency into local 2-D array (passed as argument
588        to apply_forcing S/R); add 3-D diagnostics for ptracers forcing tendency.
589    
590    checkpoint65 (2014/07/18)
591    o pkg/fizhi:
592      - add parenthesis around fizhi tendencies in fizhi_tendency_apply.F: this
593        affects results at machine truncation level. Update output of experiments
594        fizhi-cs-32x32x40 (12 digits for cg2d) & fizhi-cs-aqualev20 (13 digits).
595    o pkg/seaice: more clean up
596      - rename TAF common block tapes to be more consistent and remove
597        unnecessary duplicates
598      - add store directives to remove more recomputations, but use smaller
599        tapes (and adjust keys) when SEAICE_LSR_ADJOINT_ITER is undefined.
600        The idea behind this flag is to reduce the memory footprint when the
601        adjoint of the LSR is not required. As of now, defining the flag
602        SEAICE_LSR_ADJOINT_ITER increases 4 common block tapes for 2D field by
603        a factor of SOLV_MAX_FIXED (=500 by default in SEAICE_SIZE.h).
604        For experiment offline_exf_seaice, this means on a linux box with gfortran
605        nearly a factor of 10 (but keep in mind there is mostly seaice code in
606        this experiment):
607        > size mitgcmuv_ad
608        text    data        bss     dec        hex
609        5100659 1216  220458952  225560827  d71c8fb
610        5339425 1200 1868783272 1874123897 6fb4dc79 (SEAICE_LSR_ADJOINT_ITER)
611        but only a moderate increase of 36% for global_ocean.cs32x15:
612        text    data        bss     dec        hex
613        6695027 1648 1014578664 1021275339 3cdf6ccb
614        6695203 1648 1382505320 1389202171 52cd8afb (SEAICE_LSR_ADJOINT_ITER)
615      - note: there are still recomputations in global_ocean.cs32x15 and
616        offline_exf_seaice and the gradient agreement changes (gets a
617        little worse) for global_ocean.cs32x15 (-> update output_adm.seaice.txt)
618      - in general, the AD gradients still are wrong
619    o OpenAD
620      - clean up code_oad/ directories somewhat by moving files
621        dontCompile, dontTransform, keepOriginal to OAD_support/
622    o model/src:
623      - using MOM fluxform and Non-Lin Free-Surf with momDissip_In_AB=F
624        (not currently tested): add dissipation terms before NLFS rescaling of
625        tendencies (previously done after).
626    o pkg/diagnostics:
627      - write stats-diags in ascii file with more digits (same as in monitor).
628    o pkg/down_slope:
629      - drop the bi,bj dimension of argument recip_hFac in S/R DWNSLP_APPLY; with
630        NLFS (not tested), use new recip_hFac value in order to conserve tracer.
631    o model/src:
632      - new file "apply_forcing.F" containing all the code previously in
633        external_forcing.F, but with new argument list: pass, as new argument,
634        the current level tendency array to update (instead of a direct update
635        of the common bloc array). Change the corresponding calls.
636      - add CPP option USE_OLD_EXTERNAL_FORCING (default is undef) to use
637        EXTERNAL_FORCING_U,V,T,S subroutines (for backward compatibility).
638    o pkg/seaice/seaice_lsr, a little bit of clean up
639      - rearrange some code blocks, so that now all calculations for
640        setting up the right-hand-sides done within one single block
641        (I find that easier to read and understand)
642      - rearrange freedrift-code to reduce the number of ifdefs
643      - adjust some indentations and comments
644    
645    checkpoint64z (2014/07/10)
646    o model/src and several pkgs:
647      - change argument list of all S/R called from external_forcing.F and
648        called from ptracers_forcing.F (renamed to ptracers_apply_forcing.F)
649        to pass, as argument, the current level tendency array to update
650        (instead of a direct update of the common bloc array).
651      - change also (in the same way) argument list of PTRACERS_APPLY_FORCING;
652      - rename taueddy_external_forcing.f to taueddy_tendency_apply.F
653    o pkg/seaice/seaice_lsr.F
654      - always initialize local arrays in seaice_lsr_tridiagu/v
655      - add more local tapes to seaice_lsr_tridiagu/v
656      - move storing u/vice(:,:,bi,bj) out of seaice_lsr_tridiagu/v, but
657        keep it in bi/bj loop; this seems to be essential
658      - gradients are still wrong but only by 4-7 orders of magnitude
659        instead of 15 orders of magnitude, lab_sea improves a little
660    o pkg/seaice
661      - (pkg/autodiff) remove storing/restoring of seaiceMaskU/V that
662        generates unnecessary code in seaice_lsr_ad
663      - add more store directives in seaice_lsr to avoid unnecessary code
664        in seaice_lsr_ad
665      - exclude some residual computations in seaice_lsr when
666        ALLOW_AUTODIFF_TAMC is defined in order to avoid unnecessary code
667        in seaice_lsr_ad
668      - add more storing, a new tape (model/src/the_main_loop.F) and
669        another key for SEAICE_LSR_VECTORIZE_ZEBRA (the local keys ilockey
670        and klockey should be checked by a specialist)
671      - modify ( define SEAICE_VECTORIZE_LSR and SEAICE_LSR_ADJOINT_ITER )
672        and update lab_sea after previous changes in pkg/seaice below
673    o pkg/autodiff:
674      - introduce useSmoothCorrel2DinAdMode, SEAICEapproxLevInAd, and
675        viscFacInAd : run time parameters allowing for adjoint switches
676        note : logic for useSmoothCorrel2DinAdMode is in ctrl_readparms.F
677    o pkg/ecco:
678      - introduce cost_gencost_boxmean.F that computes a box mean
679        temperature (for use in adjoint sensitivity studies).
680    o model/src/set_defaults.F : initialize viscFacAdj to 1.
681    o pkg/mom_common/mom_calc_visc.F:
682      - ifdef ALLOW_AUTODIFF then include viscFacAdj factor.
683    o pkg/seaice/seaice_summary.F:
684      - statement for SEAICEadjMODE now in autodiff_readparms.F
685    o pkg/seaice:
686      - remove some store directives and add new ones in an effort to get
687        finally rid off the recomputation warnings. This is successful
688        when SEAICE_VECTORIZE_LSR ***and*** SEAICE_LSR_ADJOINT_ITER are
689        defined (i.e. no extensive recomputation warnings left), but there
690        are still too many recomputations on the solver iteration level
691      - define SEAICE_VECTORISZE_LSR in offline_exf_seaice/code_ad/SEAICE_OPTIONS.h
692      - move definition of MPSEUDOTIMESTEPS into TAMC-block in
693        SEAICE_SIZE.h
694      - add a store directive in S/R seaice_calc_viscosities
695    o pkg/seaice (ITD code):
696      - fix definition of Hlimit for multi-threaded case
697      - use double precision arithmetic to compute Hlimit: this affects results;
698        update output of experiment seaice_itd.
699    o replace content of verification/seaice_itd
700      - instead of a 1D column use the configuration of offline_exf_seaice
701        to test the ice thickness distribution code with ridging
702      - this is a first shot at this experiment
703      - change of some defaults of ridging parameters SEAICEhStar (from
704        100 to 25) and SEAICEmuRidging (from 5 to 3) in seaice_readparms.F
705        and lot of new comments.
706    
707    checkpoint64y (2014/06/20)
708    o pkg/seaice/seaice_reg_ridge.F:
709      - modify the regularization of very small volumes of ice; only check
710        total volume HEFF, and do not apply correction to individual ice
711        classes because that leads to funny patterns in the heat and fw-fluxes
712        into the ocean. Adjust seaice_itd/results/output.txt
713      - replace nITD by SEAICE_multDim in loop-ranges
714    o pkg/exf:
715      - add code to process the case field period = -12. with UV interpolation.
716      - move debug print (formerly active when exf_verbose=T) from EXF_getFFieldRec
717        into S/R that calls it (i.e., exf_set_gen.F, exf_set_uv.F & obcs_exf_load.F)
718    o verification/global_with_exf:
719      - switch all fields period to -12. (was previously untested) in input/data.exf
720        (but keep secondary test ".yearly" unchanged); update the reference output.
721    o pkg/cal:
722      - new calendar type "noLeapYear" for 365 days calendar without any leap year.
723    o pkg/exf:
724      - new integer parameter "exf_debugLev" (default set to main model debugLevel)
725        to replace logical switch "exf_verbose"
726      - report in STDOUT when loading a new record (if exf_debugLev >= 3)
727    o pkg/sbo:
728      - update from Katherine Quinn: evaluate mass directly from density and SSH
729        (budget using Finite Volume method) instead of from bottom pressure.
730      - allow testreport to collect few selected SBO output ; tested in exp.
731        global_ocean.90x40x15 (after updating the results, to include SBO output).
732      - fix some multi-threading issues (in output part).
733    o model/src & most packages:
734      - always call {PKG}_READPARMS even if corresponding use{PKG}=F;
735      - in {PKG}_READPARMS, in case use{PKG}=F: add a call to new S/R
736        PACKAGES_UNUSED_MSG to print a weak warning when parameter file
737        "data.{pkg}" exist ; and leave the S/R (return) just after.
738      - more standard LAND pkg interface (land_init_fixed.F, land_check.F).
739        + call LAND_READPARMS from packages_readparms.F
740    o pkg/seaice:
741      - remove code that resets useThSice in S/R seaice_readparms and
742        replace it by a warning in S/R seaice_check
743      - remove parameter MULTDIM, replace with nITD and runtime
744        parameter SEAICE_multDim (still hard-wired to nITD if
745        SEAICE_ITD is defined)
746    
747    checkpoint64x (2014/05/24)
748    o verification/lab_sea:
749      - update adjoint and TLM output following changes to pkg/salt_plume
750      - un-do the update after putting back local recip_Cp in few places.
751    o pkg/salt_plume: modifications by An Nguyen:
752      - add capability to do brine rejection (salt-plume) as function of
753        volume+tracers (instead of only salinity tracer).
754      - conserve volume by exchanging volume from each kLev to above to
755        accommodate in-coming brine volume
756      - store surface and klev exchanged fraction + volume in 4 new 3-d arrays
757      - switch KPP surf buoyancy due to brine forcing to 3-d
758        (3 more 3-d arrays, 2 for SPforcing[T,S], 1 for boplume)
759      - add salt_plume_volfrac, salt_plume_apply, salt_plume_tendency_apply_t
760      - unrelatedly, also add ad-hoc capability to vary salt_plume scheme
761        in East/West Arctic.
762    o pkg/sbo:
763      - incorporate modifications from Katherine Quinn to enable the use of sbo
764        pkg in ECCO-v4 set-up ; remove SBO-TimeAve output ; add monitor-like
765        output for future testreport verification (unfinished).
766    o pkg/atm_phys:
767      - change diagnostics (AtPh_Trf & AtPh_Qrf) of DARGAN_BETTSMILLER S/R:
768        skip the reseting of t_ref & q_ref to initial t & q ; this preserve the
769        output of S/R CAPECALCNEW (Parcel temp & q) for diagnostics.
770    o pkg/seaice
771      seaice_calc_ice_strength.F: modify expression to avoid divisions
772        (affects truncation)
773      seaice_do_ridging.F: clean up the insectarium
774      - fix a bug that was compensated by areaScaling (-> remove areaScaling code)
775      - added SEAICEsnowFracRidge to redistributed snow (2nd bug)
776      - set closing/openingRate to zero where no extra iteration is need (3rd bug)
777      - add some debugging information and error messages (warnings)
778    o model/src: modifications relatd to atmosphere p*:
779      - Switch to more accurate p* coordinate slope term (calc_grad_phi_hyd.F)
780      - With p* or Sigma-P, use constant reference Pot.Temp (thetaConst) instead
781        of vertical profile tRef in geopotential background and anomaly.
782      - Acount for true p* correction in theta <-> T conversion in pkg/aim_v23
783        and pkg/atm_phys.
784      - Update FWD output of experiments: aim.5l_cs (x2), fizhi-cs-32x32x40,
785        fizhi-cs-aqualev20, fizhi-gridalt-hs, tutorial_held_suarez_cs, cpl_aim+ocn.
786    o pkg/seaice: fix a bug in seaice_prepare_ridging.F, forgot a sqrt
787    o pkg/ptracers: compute ptracer source/sink due to linear free surface.
788        not used right now, but can be used in BGC packages to fix conservation.
789    o pkg/dic, pkg/gchem: move tracer_meanarea to gchem, so it can be used by
790        other packages too.
791    o pkg/seaice/seaice_calc_ice_strength.F: replace SEAICE_rhoSnow by
792        SEAICE_rhoIce in the Rothrock (1975)-type strength calculations (bug fix)
793    o model/src:
794      - since we have several heat capacity (even in model/src), define "recip_Cp"
795        as local variable (no longer in common block) to avoid any confusion.
796      - add thetaConst in PARAMS.h (to be used with pStar or sigma-P coords).
797    o pkg/exf:
798      - from Jeff Scott: add option (#define EXF_CALC_ATMRHO) to calculate local
799        air density as function of air Temp, Humidity and atm pressure.
800    
801    checkpoint64w (2014/05/02)
802    o verification:
803      - update output_adm.txt files for experiment global_ocean.cs32x15 (seaice &
804        seaice_dynmix) and lab_sea (primary test & noseaicedyn): moving/changing
805        code from seaice_growth.F & seaice_advdiff.F to new ridging routines
806        seaice_reg_ridge.F seaice_do_ridging.F affects AD gradient
807        (down to 8-7 matching digits for global_ocean and 5-6 for lab_sea).
808    o model/src: for atmosphere in p* coords:
809      - store factor rStarFacC**atm_kappa (= pStarFacK) in common block
810      - implement more accurate p* coordinate slope term (in calc_grad_phi_hyd.F),
811        but not yet activated.
812    o pkg/seaice: fix restart problem for ITD with new ice strength parameterisation:
813      - move computation of opnWtrFrac = 1-AREA to before computing ice strength
814      - this changes the results (but not for any verification experiment, because
815        none tests this), but avoids having an extra field in the restart files
816    o pkg/seaice: remove global variable TICE (not needed)
817      - replace by TICES or local variable where necessary (cost_seaice_test,
818        seaice_diagnostics_state)
819      - move copying TICE to TICES from seaice_check_pickup to seaice_read_pickup
820      - use specific read/write routines for reading and writing individual leves
821        of a multilevel field
822    o pkg/ctrl & model/inc:
823      - move additional anomaly fields of control vars (related to options:
824         ALLOW_KAPGM_CONTROL, ALLOW_KAPREDI_CONTROL and ALLOW_BOTTOMDRAG_CONTROL)
825        from DYNVARS.h into new header file: CTRL_FIELDS.h
826    o pkg/seaice: some small modifications to the ridging code
827      - make fw2ObyRidge a global variable and add the freshwater flux to
828        seaice_growth
829      - pass actual thickness from seaice_prepare_ridging, so that it is
830        computed only in one place and compute it in the same way as in
831        seaice_growth
832      - initialise more fields in seaice_do_ridging that where cause floating
833        point exceptions over land
834    o pkg/seaice: preparations for ridging code and first real ridging code
835      - move most of "PART 1" of S/R seaice_growth into a new and separate
836        S/R seaice_reg_ridge that will both regularize the state variable after
837        advection call the actual ridging routine;
838      - requires to make 5 fields global fields: d_HEFFbyNEG,d_HSNWbyNEG,
839        d_AREAbyRLX,d_HEFFbyRLX,saltFluxAdjust;
840      - remove ridging code from seaice_advdiff
841      - clean up remaining part 1 of seaice_growth in an attempt to make it
842        more readable (this is probably subjective)
843      - call seaice_itd_redist once in the initialisation phase to have the initial
844        conditions in the correct category
845      - finally: add new ridging routine for ITD code
846    
847    checkpoint64v (2014/04/11)
848    o pkg/ecco:
849      - add runtime parameters mdt[start,end]date[1,2]
850      - rename variable "tpmean" as "mdt" and "topexmeanfile" as "mdtdatfile"
851    o pkg/seaice:
852      - make deltaC a global variable, so that it can be used in ridging code
853      - first step towards ridging: introduce new routines that compute
854        ice strength based on ridging parameters
855      - add diagnostic for HSNOWITD
856      - add opnWtrFrac as a global variable (required for ridging scheme)
857    o pkg/salt_plume + pkg/seaice/seaice_growth.F
858      - add SALT_PLUME_IN_LEADS flag to activate pkg/salt_plume only when ice
859        AREA exceeds a threshold (code contributed by I.Fenty in 2011)
860    o verification/hs94.1x64x5:
861      - leave ALLOW_AUTODIFF_TAMC undefined in code_oad/AUTODIFF_OPTIONS.h
862      - do not use ECCO_CPPOPTIONS.h anymore for TAF & OpenAD Adjoint tests.
863    o autodiff:
864      - Start to include explicitly AUTODIFF_OPTIONS.h, COST_OPTIONS.h,
865        and CTRL_OPTIONS.h in src files (to enable to skip the ECCO_CPPOPTIONS.h)
866        For now, only in pkgs used in verification/hs94.1x64x5.
867      - Replace ALLOW_AUTODIFF_TAMC by ALLOW_AUTODIFF (except for tape/storage
868        which are specific to TAF/TAMC).
869      - Replace ALLOW_AUTODIFF_OPENAD by ALLOW_OPENAD:
870        since ALLOW_OPENAD is defined in PACKAGES_CONFIG.h (any time pkg/openad
871        is compiled), this simplifies/reduces which *_OPTIONS.h file to include.
872      - OpenAD: change Makefile to generate the appropriate AD_CONFIG.h when
873        building mitgcmuv_ad (make adAll).
874    o pkg/ecco:
875      - cost_gencost_seaicev4.F:
876         reformulate proxy cost as function of sst and local param SEAICE_freeze
877         change cost names from siv4-[sst,vol] to siv4-[deconc,exconc]
878      - add stop statement if old names siv4-[sst,vol] are used
879      - add snapshots + cost reports for atmospheric longwave
880      - remove factor 0.1 in front of wtau[u,v]
881      - replace never used flag ALLOW_TMI_COST_CONTRIBUTION with
882         ALLOW_TMI_SST_COST_CONTRIBUTION
883    o pkg/atm_phys:
884      - add some diagnostics for Short-wave and for convection S/R.
885    o pkg/seaice/seaice_growth:
886      - fix a bug in the lateral melt parameterization for SEAICE_ITD
887        in seaice_growth; tempFrz needs to be computed inside the i/j-loop
888      - rearrange loop order for better vector code in the same code block
889      - rewrite the floeDiameter formula to have fewer divisions
890      -  (miraculously) none of this changes the results of seaice_itd
891    o pkg/smooth:
892      - move param smooth2Ddiffnbt to pkg/ecco
893    o pkg/salt_plume:
894      - salt_plume_frac.F:
895         clean up local param names
896         reformulate (1-frac) to frac; original 1-frac was based on swfrac code
897    o pkg/rw:
898      - add RS version of S/R READ_MFLDS_LEV.
899    o pkg/streamice:
900      - fix the restart test by writing/reading pickup_streamice files.
901    o pkg/seaice:
902      - refine checks for jfnk-related parameters
903      - comment out if statement with SEAICEuseIMEX parameter as long as there
904        is no IMEX code to avoid confusion and surprises
905    
906    checkpoint64u (2014/03/07)
907    o verification/MLAdjust:
908      - rename secondary test suffix:
909         1.leith  -> A4FlxF  + switch to flux-form & add side-drag
910         0.leithD -> AhFlxF  + switch to flux-form
911         0.smag   -> AhVrDv  (use Vorticity-Div. visc form) + add side-drag
912         0.leith  -> AhStTn  (use Strain-Tension visc form) + add side-drag
913    o pkg/mom_vecinv:
914      - remove unused arguments from S/R MOM_VI_HDISSIP & MOM_HDISSIP (as it used
915        to be before mom_calc_visc.F)
916      - skip the call to MOM_CALC_TENSION & MOM_CALC_STRAIN if not needed.
917      - add 2nd copy of vort3 & strain that knows about lateral BC (free/no slip):
918        this is simpler for the adjoint and for diagnostics.
919    o model/src + pkg/momentum:
920      - add input files for  2-D additional Western and Southern cell-edge wall
921         (e.g., to add "thin-wall" where it is =1).
922      - fix sideDrag option for thin-walls with Non-Lin Free-Surf
923        using 2nd hFacZ that is computed from initial (fix domain) hFac
924      - known limitations of thin wall implementation: not yet coded for sigma
925        coords; not working with CD-scheme neither.
926    o pkg/seaice:
927      - rename recently introduced parameters from (wrong name) AB to
928        BDF (backward difference time discretisation)
929      - retire runtime parameters SEAICEuseAB2, SEAICE_abEps
930    o tools/adjoint_options:
931      - remove setting of "OPENAD=true" (now set by command line "genmake2 -oad")
932    
933    checkpoint64t (2014/02/01)
934    o pkg/ecco
935      - add compile flag ALLOW_GENCOST_TIMEVARY_WEIGHT in ECCO_OPTIONS.h and
936        runtime logical flag gencost_timevaryweight to read daily sea-ice sigma
937      - replace hard-coded record number and period which only work for monthly
938        with read-in runtime param that works for other periods (month,day,year)
939    o pkg/thsice
940      - corrected store directive fixes thsice adjoint gradient checks
941    o genmake2 & testreport:
942      - add genmake2 option "-oad" to generate a Makefile for OpenAD built and
943        in this case, use tools/adjoint_options/adjoint_oad as default AD optfile.
944        Update testreport accordingly. No need to set "export OPENAD=true"
945        in adjoint_options/adjoint_oad anymore (will be removed later).
946    o pkg/shelfice:
947      - put T & S shelfice forcing into model surfaceForcing_T,_S (for now,
948        only if SHELFICEboundaryLayer=F); Change model/src/external_forcing.F
949        so that surface forcing applies to k=kSurf if using pkg/shelfice.
950    o pkg/ctrl, pkg/grdchk, pkg/ecco:
951      - Changes to make GENARR more modular (i.e. invisible if not used)
952    o model/src/temp_integrate.F and salt_integrate.F
953      - re-include store directives that were removed on Dec 27th.
954    o model/src/external_forcing_surf.F
955      - add storage directives for EmPmR and PmEpR to avoid recomputation of
956        seaice_model in the adjoint that is problematic when seaice_model is
957        turned off in the adjoint. The resolved issue dated back to July when
958        EXTERNAL_FORCING_SURF call was moved.
959        Update global_ocean.cs32x15/*/output_adm.seaice_dynmix.txt accordingly.
960    o pkg/exf/exf_check.F
961      - fix a small bug again (originally found by Wentao Liu, now found again)
962      - streamline error output
963    o pkg/streamice and aim_v23:
964      - replace a few "_EXCH_XY_RL (" with "_EXCH_XY_RL(", so that
965        Apple's /usr/bin/cpp knows what to do:
966        Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)
967        Target: x86_64-apple-darwin13.0.0
968    
969    checkpoint64s (2014/01/05)
970    o tools/adjoint_options:
971      - switch to fastopt.net TAF server (instead of default fastopt.de) for
972        AD optfiles adjoint_diva & adjoint_f95 (similar to adjoint_default).
973    o model/src:
974      - remove some unnecessary TAF storage directives in forward_step.F and
975        in dynamics.F (note: not always removed by TAF, e.g., double storage
976        of kappaRU,kappaRV in former version of dynamics.F).
977    o model/src & pkg/ptracers:
978      - call directly GAD_IMPLICIT_R & IMPLDIFF + DWNSLP_APPLY from temp_integrate.F
979        salt_integrate.F and ptracers_integrate.F (instead of from thermodynamics.F)
980        and remove ptracers_dwnslp_apply.F & ptracers_implicit.F
981      - call MATRIX_STORE_TENDENCY_EXP for each tracer (in ptracers_integrate.F)
982      - add fZon & fMer as output argument of S/R GAD_CALC_RHS.
983      - update TAF AD-output of experiments global_ocean.90x40x15 (13 for AD-grad).
984    o useSingleCpuInput separates single-CPU input from single-CPU output;
985        for now only implemented for in exf_interp_read.F
986    o verification/advect_xy:
987      - fix missing EXCH call in local version of ini_salt.F and update output.
988    o momentum diagnostics:
989      - fix which deltaT is used in Total-Tendency diagnostics.
990      - fix typo in diagnostics for momentum tendency from AB.
991    o pkg/seaice/seaice_lsr.F: fix an initialisation bug for the
992        SEAICE_VECTORIZE_LSR_ZEBRA option that lead to NaNs on a NEC-SX8
993    
994    checkpoint64r (2013/12/08)
995    o verification/*/results:
996      - Update reference output of experiments that were passing with just 13 digits
997         (make it easier to detect future changes in results)
998    o model/src & pkg/ptracers:
999      - move calls to GAD_ADVECTION (Multi-Dim advection) from thermodynamics.F to
1000        inside temp_integrate.F and salt_integrate.F and from ptracers_advection.F
1001        to inside ptracers_integrate.F ; remove ptracers_advection.F
1002    o coupling interface pkgs:
1003        [atm_compon_interf, ocn_compon_interf & atm_ocn_coupler]
1004      - change the config check to test the agreement of Ocean Depth
1005        with ATM land/sea mask (instead of ATM orography);
1006      - send to coupler the number of coupler time-steps to do for this run:
1007        this allows to check for consistency and don't need anymore to be
1008        specified in parameter file "data";
1009      in coupler:
1010      - check consistency of RunOff map versus Ocean Depth and ATM land/sea mask.
1011      - improve report to log-file of config setting (pass log-file unit to few S/R)
1012    o pkg/compon_communic:
1013      - add coupling send/receive for non-tiled integer vector;
1014      - add S/R to check and stop if any proc has an error (similar to
1015        eesupp/src/stop_if_error.F but single thread and across Comm_World).
1016    o pkg/exch2:
1017      - in exch2*_get_rx[1,2]: use new list "W2_tileIndex" to replace search
1018        through list of all tiles my proc owns.
1019    o model/src:
1020      - AUTODIFF only: in calc_adv_flow.F, recompute rTransKp (instead of copying
1021        from rTrans) to simplify dependencies (no need to store rTrans anymore in
1022        calling S/R); this affects AD results at machine truncation level:
1023        update AD-output (TAF) of experiments: 1D_ocean_ice_column,
1024        bottom_ctrl_5x5 & obcs_ctrl (12 digits for AD grad, same FWD grad).
1025    o tools/build_options:
1026      - simplify Warnings options (-ieee & -devel cases) in linux_amd64_gfortran
1027    o coupling interface pkgs:
1028        [compon_communic, atm_compon_interf & ocn_compon_interf]
1029      - move declaration of local array "ibuf" out of header file "CPLR_SIG.h"
1030        to each S/R that needs it; remove un-used variables.
1031      - change component tile registration (cpl_register.F in both compon_interf
1032        and mitcomponent_tile_register.F) to pass the full list of tiles
1033        information (including bi,bj) in 1 vector (instead of in a bi,bj matrix).
1034      - with pkg/exch2: adopt the same convention used for I/O to define mapping
1035        towards coupler global array (unless W2_useE2ioLayOut=F):
1036         a) can now use different tiling between atm & ocn comp.
1037         b) no needs to modify the run-Off map when changing tiling (was needed
1038            even if using the same tiling between atm & ocn).
1039         c) will allow to run with blank-tiles in 1 component (e.g., for ocean
1040            full land tiles); not yet tested.
1041      - check for valid mapping from comp. tile to coupler global array
1042      - improve report of tile registration results to log file.
1043    o pkg/exch2:
1044      - in eesupp/src/eeboot.F: move call to W2_EEBOOT before Coupler
1045        tile-registration (CPL_REGISTER);
1046      - activate (un-comment) definition and setting of "W2_tileIndex" list to
1047        store the local bi,bj indices of each tile;
1048      - also print bi,bj in local report to log file;
1049      - fix pkg/debug/debug_cs_corner_uv.F for the case nSy > 1 (left from
1050        Jun 2009 modif of pkg/exch2).
1051    o testing on baudelaire:
1052      - run 2 tests at a time: no significant slow down (since enough cpu) and
1053        get the full set of test done earlier
1054      - switch the ifort test to "-devel" ; run the OpenAD test everyday.
1055    o model/src/thermodynamics.F and routines called from it:
1056      - pkg/gmredi: gmredi_residual_flow.F (replacing gmredi_calc_uvflow.F &
1057        gmredi_calc_wflow.F) to update eulerian velocity (input) into residual
1058        velocity (outp) by adding bolus velocity.
1059      - model/src: calc_adv_flow.F (replacing calc_common_factors.F) to compute
1060        mass transport from velocity + lateral grid cell area
1061      - rename calc_gt.F to temp_integrate.F (includes call to TIMESTEP_TRACER)
1062      - rename calc_gs.F to salt_integrate.F (includes call to TIMESTEP_TRACER)
1063     in thermodynamics.F
1064      - remove k from thermodynamics.F and move it to temp_integrate.F
1065        salt_integrate.F and ptracers_integrate.F (now done inside the tracer
1066        loop).
1067      - compute locally (in thermodynamics.F) 3-D velocity field that is used to
1068        advect tracers; pass it as argument to GAD_ADVECTION, GAD_SOM_ADVECT,
1069        PTRACERS_ADVECTION, TEMP_INTEGRATE, SALT_INTEGRATE, PTRACERS_INTEGRATE,
1070        GAD_IMPLICIT_R and PTRACERS_IMPLICIT
1071      - update AD-output (TAF & OAD) of experiments: 1D_ocean_ice_column,
1072        global_ocean.90x40x15, tutorial_global_oce_biogeo and
1073        tutorial_tracer_adjsens (+ TLM output).
1074    o tools/OAD_support and (verification/*/) code_oad:
1075      - OAD_support/cb2mGetModules.csh: add PACKAGES_CONFIG.h in header file to
1076        module conversion ; remove unneeded CPP_EEOPTIONS.h.
1077      - code_oad/CPP_OPTIONS.h: remove PACKAGES_CONFIG.h and use a more standard
1078        version (closer to model/inc/CPP_OPTIONS.h).
1079    o model/src:
1080      - remove parameter "useOldFreezing" from PARAMS.h and push it to the
1081        retired list of parameters (routine FREEZE has been replace by surface
1082        freezing (10.yrs ago) and by pkg/frazil (interior freezing).
1083    o pkg/gmredi:
1084      - add option (GM_CALC_TRANSP_FROM_VEL) to compute transport directly from
1085        velocity (same scheme but affects machine truncation) for GM_AdvForm.
1086      - update output of FWD experiments: front_relax.bvp,
1087        global_ocean.90x40x15.dwnslp, global_ocean.cs32x15 and ideal_2D_oce.
1088    
1089    checkpoint64q (2013/11/17)
1090    o verification:
1091      - generate new output on baudelaire (gfortran, -ieee) for OpenAD experiments
1092        tutorial_global_oce_biogeo and global_ocean.90x40x15.
1093      - generate new output (growth & melt) for seaice_itd experiment after
1094        updating the input pickup_seaice files (previously wrong).
1095    o pkg/cost:
1096      - define a "final cost function" for each tile, and use GLOBAL_SUM_TILE_RL
1097        (instead of _GLOBAL_SUM_RL) to get the final cost from all procs & threads:
1098        o this fixes global-sum value if multi-threads (since GLOBAL_SUM_RL
1099          cannot be applied to var in common block).
1100        o allows to get results independent of tile-per-proc setting (if using
1101          slower GLOBAL_SUM_SEND_RECV option).
1102      - update accordingly: seaice_cost_final.F, shelfice_cost_final.F,
1103        thsice_cost_final.F and ecco_cost_final.F (this one affects lab_sea
1104        forward gradients: update output).
1105      - update */code_oad/externalDummies.F by adding dummy GLOBAL_SUM_TILE_RL
1106        S/R and, for most exp., also comment out GLOBAL_SUM_R8.
1107    o pkg/mom_common:
1108      - move to pkg/mom_common and model/src (previously in tutorial_deep_convection
1109        code) 2nd version of isotropic 3-D Smagorinsky code interface: strain and
1110        viscosity are locally declared in dynmics.F and pass as argument to CALC_GW;
1111        ensure that all field value that are used are set.
1112    o tutorial_deep_convection (smag3d):
1113      - add missing scaling in mom_calc_smag_3d.F;
1114      - set smag3D_coeff in input.smag3d such that results do not change.
1115    o pkg/dic:
1116      - change dic_cost.F to compute cost on each tile first and then apply
1117        GLOBAL_SUM_TILE_RL: this affects forward gradient of AD experiments
1118        tutorial_dic_adjoffline & tutorial_global_oce_biogeo; update output.
1119      - remove kLev argument and use GLOBAL_SUM_TILE_RL in tracer_meanarea.
1120    o eesupp/src & pkg/mdsio:
1121      - remove gather/scatter_vector.F (from eesupp) and mdsio_read/writevector.F
1122        (from pkg/mdsio) since they are no longer used for tape IO.
1123      - move simple C subroutine "setdir.c" from pkg/compon_communic to eesupp/src
1124        (+ keep a copy in pkg/atm_ocn_coupler).
1125    o verification/isomip:
1126      - split domain in 8 squared tiles (instead of just 2) for FWD, AD & OAD tests.
1127    o tools/build_options:
1128      - optfile linux_amd64_ifort11, fast (no ieee) case:
1129        to get a working restart for all experiments, add "-fp-model source"
1130        to FOPTIM (also remove "-opt-streaming-stores auto" <- this is the default).
1131    
1132    checkpoint64p (2013/10/20)
1133    o pkg/autodiff:
1134      - adread_adwrite.F: when type and length do not match ALLOW_AUTODIFF_WHTAPEIO
1135        criteria, return to simple (default) tape IO format.
1136    o pkg/mdsio (+ eesupp/src):
1137      - rewrite/simplify tape-IO S/R (new S/R MDS_READ/WRITE_TAPE replace
1138        previous MDSREAD/WRITEVECTOR) with 2 array argument from each type (R4/R8);
1139      - fix globalFile and singleCpuIO options using simpler global mapping.
1140      - new pairs of scatter/gather vector S/R (one for each type, generated from
1141        template) corresponding to simpler global mapping.
1142      - adread_write.F: switch to new S/R (but leave old calls commented) and write
1143        to globalFile when parameter globalFiles is set to True.
1144      - switch on useSingleCpuIO in AD experiments: global_ocean.90x40x15 & isomip.
1145    o pkg/autodiff:
1146      - adread_adwrite.F: add a hack for RS arrays (when RS=real*4);
1147        with ALLOW_AUTODIFF_WHTAPEIO defined, since corresponding (real*4) is
1148        missing, just add a STOP if array type do not match.
1149    o pkg/exf:
1150      - to allow to use seaice-fraction from pkg/exf in other pkgs than pkg/seaice:
1151         rename CPP option EXF_ALLOW_SEAICE_RELAX to EXF_SEAICE_FRACTION
1152         and rename array obsSIce to exf_iceFraction.
1153    o tutorial_deep_convection:
1154      - add 1rst version of isotropic 3-D Smagorinsky code (from Louis-Philippe),
1155        for now all in this exp. code dir.
1156      - add secondary test using Smag-3D viscosity (keep very low backgroud visc for
1157        testing) and flux-limter advection scheme for Temp. (no explicit diffusion).
1158    o eesupp/src:
1159      - added SINGLE_DISK_IO option because reading of parameter files on
1160        very large number of processors did not work with existing set-up
1161    
1162    checkpoint64o (2013/09/25)
1163    o pkg/atm_phys & atm_compon_interf:
1164      - allows for coupling of gray-atmosphere (atm_phys) with ocean.
1165    o tools/build_options:
1166      - switch from "-fPIC" to "-mcmodel=medium" in optfiles: linux_amd64_gfortran
1167        & linux_amd64_ifort11 and in linux_amd64_g77 & linux_amd64_open64 also
1168        remove CPP setting (was identical to genmake2 default).
1169    o pkg/gmredi & model/src: Some updating and work done on the residual model.
1170      - created new file model/src/calc_eddy_stress.F to calculate the eddy stress.
1171      - fixed up the calculation of the eddy stress and how it is added to the
1172        external forcing via taueddy_external_forcing.F
1173      - at the moment, it is very experimental and only works with the variable eddy
1174        diffusivity calculated in gmredi_k3d.F
1175    o pkg/seaice/seaice_check.F: add a check to catch the case of specifying
1176        lw/swfluxfile instead of lw/swdownfile in data.exf together with pkg/seaice
1177    o testreport (& tools/do_tst_2+2):
1178      - for MPI test, set default COMMAND to 'mpirun -v -np TR_NPROC ./{executable}'
1179    o tools/build_options: linux_amd64_gfortran & linux_amd64_ifort11:
1180      - remove CPP='cpp -traditional -P' (this is genmake2 default)
1181      - add switch (for big setups) to use 'medium' memory-model (but leave it
1182        commented out for now). Note: needed with FC 19 to compile big setups.
1183    o pkg/atm_compon_interf:
1184      - regroup per field origin (model & pkgs) the coupling storage routines
1185         (which accumalate in time each coupling field)
1186      - move bi,bj loops inside atm_store_my_data.F and store also wind-stress;
1187        update accordingly + simplify aim_do_physics.F
1188    
1189    checkpoint64n (2013/08/26)
1190    o pkg/bbl:
1191      - update formulation to reduce dispersion of tracer properties in bbl
1192      - replaced horizontal and vertical transport parameters with velocities
1193      - changes results for verification/global_with_exf.yearly
1194    o verification/halfpipe_streamice:
1195      - change to matrix construction; update both Fwd & AD output.
1196    o verification/tutorial_tracer_adjsens:
1197      - OpenAD test: switch to vector-invariant momentum since fluxform with
1198        rStar causes problems with OpenAD; update output.
1199    o tools:
1200      - genmake2: define a common prefix for all temp-file names ; move them
1201        to local /tmp disk (but would be easy to move them back);
1202      - xmakedepend: apply the same switch for temp-files.
1203    o pkg/offline:
1204      - changes for use with rStar (NLFS): assume that we continue to provide
1205        UVELMASS/hFacW_ini & VVELMASS/hFacS_ini (hFacWi,S_ini as written in grid
1206        output files) and apply r* scaling at each time-step (function of the time
1207        varying Eta field); use normal pickup files (needed for restart with NLFS).
1208    o adjoint with OpenAD:
1209      - move OpenAD-specific files from verification/OpenAD/code_oad_all to a new
1210        package openad.  This package has to be compiled for all runs with OpenAD
1211        instead of specifying code_oad_all as a modification directory.
1212      - link the fortran templates from tools/OAD_support to the build directory
1213        for preprocessing to avoid conflicts between different setups compiled
1214        simultaneously and simplify cleanup.
1215    o pkg/exf:
1216      - in exf_getforcing.F: comment out most of the EXCH calls (fields used by
1217        main model or other pkgs are exchanged in EXF_MAPFIELDS).
1218    o model/src:
1219      - do_stagger_fields_exchanges.F: skip EXCH calls when using pkg/offline
1220        (similar to do_fields_blocking_exchanges.F).
1221    o tools/genmake2:
1222      - remove TAF output src code just before calling staf (when not doing a fresh
1223        built, will stop if things go wrong with staf).
1224      - fix target "adobj" (left from TAF version-2 transition)
1225    o pkg/diagnostics:
1226      - add a parameter to track the status of pkg/diagnostics activation;
1227        this replace/extend the use of logical param "settingDiags" (to check
1228        when adding diag to the list) to also check any DIAGNOSTICS_[]FILL* call.
1229        New S/R to print error message and stop when pkgStatus is not right.
1230      - to try: add a warning when "data.diagnostics" exist but useDiagnostics=F.
1231    
1232    checkpoint64m (2013/08/13)
1233    o model/inc:
1234      - move FCORI_MACROS.h from PARAMS(_MACROS).h to GRID_MACROS.h (left from
1235        8 yrs ago modif when Coriolis arrays were moved from PARAMS.h to GRID.h)
1236    o pkg/kpp & aim_v23:
1237      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
1238    o pkg/seaice:
1239      - restore (last time on 2011/12/24) ability to compile pkg/seaice with
1240        undefined pkg/exf ALLOW_ATM_TEMP or ALLOW_RUNOFF CPP-options.
1241      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
1242    o eesupp/src:
1243      - fix check for overlap-size argument (myOLn.GT.MAX_OLY_EXCH)
1244        in exch1_rx[_ad].template (thanks to Francois Lefeuvre report).
1245    o switch to TAF version-2:
1246      - add flow directives to "freeze" naming convention for ad-routines that
1247        are used in I/O routines of adjoint state and associated common blocks
1248        that are used in adcommon.h (backward compatible with version-1)
1249      - update all ad-optfiles (in tools/adjoint_options + few local to some
1250        verification exp) to switch to latest TAF version (currently 2.5.5);
1251        merge "*_mpi" adoptfiles into the corresponding non-mpi (but commented
1252        out except for diva).
1253      - the major change with TAF version-2 is that both the differentiated
1254        routines and the forward routines (new) are returned as part of the TAF
1255        output source code. Update genmake2 accordingly.
1256      - new output for AD experiment tutorial_global_oce_biogeo (better AD gradient
1257        with version-2 when compared to TLM or FWD gradient); other experiments
1258        output show minor changes (machine truncation level); update the few AD &
1259        TLM output with 12 matching digits only (some prior to version-2 switch).
1260    
1261    checkpoint64l (2013/08/05)
1262    o model/src:
1263      - in dynamics.F, skip the call to CALC_VISCOSITY if momViscosity=F
1264      - main_do_loop.F: no longer includes additional (AUTODIFF) header files
1265        when using TAF but only if using OpenAD.
1266    o pkg/mom_common+fluxform+vecinv:
1267      - always set horiz. viscosity arrays to background value before calling
1268        MOM_CALC_VISC (in MOM_FLUXFORM & MOM_VECINV) and call S/R MOM_CALC_VISC
1269        only when using variable horiz. viscosity (useVariableVisc=T);
1270      - simplify mom_vecinv.F (only 1 block for momViscosity).
1271    o pkg/mom_common: variable horiz. viscosity in NH code
1272      - move horiz-viscosity 3-D arrays viscAh_W & viscA4_W (used in calc_gw.F)
1273        from model/inc/NH_VARS.h to pkg/mom_common/MOM_VISC.h
1274      - store in common block (in MOM_VISC.h) logical parameters: useHarmonicVisc,
1275        useBiharmonicVisc & useVariableVisc.
1276      - fix old bug (already in 1rst implementation of variable horizontal viscosity
1277        in calc_gw.F, version 1.27, 2006/06/20):
1278        horizontal bi-harmonic viscosity in gW was missing when wiscA4W=0
1279        even if variable bi-harmonic viscosity (e.g., viscA4Grid) was non-zero.
1280      - change background horiz viscosity in vertical momentum (gW) to always be
1281        viscAhW,viscA4W (instead of switching to viscAhD, viscA4D when using
1282        any type of variable viscosity, e.g., viscAh/4Grid)
1283      - change default value of viscAhW,viscA4W to viscAhD,viscA4D (instead of
1284        viscAh,viscA4) which default to viscAh,viscA4 :  this avoid missing
1285        horiz. viscosity in W eq when just setting viscAhD/Z,viscA4D/Z (since
1286        default viscAh,viscA4 is zero).
1287    o model/src:
1288      - extend length of drC & recip_drC from Nr to Nr+1.
1289    o Divided Adjoint (DIVA) with MPI:
1290      - genmake2: do not create local ./mpi_headers dir when no file to copy into.
1291      - remove option ALLOW_DIVIDED_ADJOINT_MPI (replaced by ALLOW_DIVIDED_ADJOINT
1292        and ALLOW_USE_MPI) from model/src code and from ECCO_CPPOPTIONS.h.
1293    
1294    checkpoint64k (2013/07/23)
1295    o tools/OAD_support:
1296      - avoid the need for file "oadtempflile" in insertTemplateDir.bash
1297        and remove it from genmake2.
1298    o tools/build_options:
1299      - remove MPI_HEADER_FILES_INC setting (no longer used) and comment out
1300        MPI_HEADER_FILES list (let genmake2 find the missing headers)
1301    o verification/halfpipe_streamice:
1302      - change to driving stress formulation; update both Fwd & AD output.
1303    o tools/genmake2 and Divided Adjoint with MPI:
1304      - remove default setting of MPIINCLUDEDIR from $MPIHOME (always been broken);
1305      - only create local ./mpi_headers dir if using MPI and MPIINCLUDEDIR is set;
1306      - add new variable (LOCAL_MPI_HEADERS, replace MPI_HEADER_FILES_INC) in
1307        Makefile, which is set by genmake2, and check which mpi-headers are needed.
1308        Note: need to update adjoint_options/adjoint_diva_mpi accordingly.
1309      - update target "CLEAN" (to also remove ./mpi_headers/ dir).
1310    o testreport:
1311      - changes for Divided Adjoint Run: when file "run_ADM_DIVA" is present,
1312        perform additional runs (number of additional runs is "add_DIVA_runs" taken
1313        from file run_ADM_DIVA ; should match "nchklev_3" in file "code_ad/tamc.h").
1314    o verification/lab_sea (AD test):
1315      - change to test Divided Adjoint Run in this set-up (both standard AD test
1316        and 2 secondary AD test: noseaice + noseaicedyn); drop the evp AD test.
1317    o pkg atm_ & ocn_compon_interf:
1318      - remove cpl_earlyExpImpCall=F option (was mainly a hack added for the old
1319        staggerTimeStep implementation) and disable (retired) corresponding
1320        parameter.
1321    o pkg/offline:
1322      - comment out unused field-array: ICEM, ConvectCount, hflx[01], icem[01];
1323      - add S/R OFFLINE_CHECK to print offline parameter summary
1324        and stop if loading a file that is not used;
1325      - enable to calculate GMRedi tensor, KPP mixing and convective index
1326        when the corresponding file(s) is/are not specified (but pkg is used).
1327      - comment out resetting of monitorFreq (to endTime) since it still useful
1328        for monitoring CFL numbers and checking offline fields.
1329    o OpenAD:
1330      - do not define OAD_DEBUG (in tools/adjoint_options/adjoint_oad) to get
1331        smaller standard output) and generate new (smaller) output (on baudelaire
1332        using gfortran with -ieee) for exp. tutorial_tracer_adjsens
1333    o model/src:
1334      - call EXTERNAL_FORCING_SURF outside bi,bj loops (in do_oceanic_phys.F),
1335        (where external_forcing_adjust was called) and change list of arguments;
1336      - merge external_forcing_adjust.F into external_forcing_surf.F
1337      - put surface relaxation of SST & SSS in new S/R (forcing_surf_relax.F)
1338        which also contains balancing surface relaxation (ALLOW_BALANCE_RELAX,
1339        previously in file "balance_relax.F", now removed); remove corresponding
1340        arrays in FFIELDS.h.
1341      - EXTERNAL_FORCING_SURF is now called when using pkg/offline; implement
1342        a hack for getting back surfaceForcingS (loaded from file) when using
1343        ALLOW_OLD_VIRTUALFLUX (pkg/dic, in DIC_OPTIONS.h) in offline set-up.
1344      - update output of AD test experiment global_ocean.cs32x15.seaice_dynmix
1345        (was getting only 11 digits for AD-grad, due to different truncation
1346         error in AD code).
1347    
1348    checkpoint64j (2013/07/04)
1349    o pkg/offline:
1350      - to enable the use of other features with pkg offline (e.g., obcs),
1351        also call S/R DO_OCEANIC_PHYS in offline run - more modifs to come.
1352      - comment out "allowFreezing" (now active) in 2 offline testing exp.
1353    o pkg/exf ALLOW_RUNOFTEMP
1354      - fix sign and make compatible with temp_EvPrRn .NE. UNSET_RL
1355      - ahdded RUNOFTEMP test to verification/global_ocean.cs32x15/input.seaice
1356      - changes verification/global_ocean.cs32x15/results/output.seaice.txt
1357    o pkg/atm_phys:
1358      - allows to add some damping on uVel,vVel (strength only function of k).
1359    o verification, ad-tests:
1360      - reduce length of the simulation for AD test: global_ocean.cs32x15.seaice,
1361        global_ocean_ebm and offline_exf_seaice.thsice.
1362    o verification/halfpipe_streamice:
1363      - found a bug in s/r pkg/streamice/streamice_advect_thickness which caused
1364        flux input boundary conditions to be ignored; a fix for this bug changed
1365        verification results for forward test.
1366      - add adjoint test.
1367    o pkg/ptracers:
1368      - allow to restart without SOM pickup (resetting SOM to zero).
1369    o pkg/gmredi:
1370      - New parameterisation for the calculation of K and (GM_PsiX,GM_PsiY) added.
1371      - It uses mixing length theory and suppression by steering level effects to
1372        calculate a diffusivity used in the Redi tensor (see Bates et al., submitted
1373        to JPO, for more details).
1374      - It also uses the diffusivity to calculate an eddy induced streamfunction
1375        based on a PV closure (rather than a buoyancy closure as in GM).
1376      - New files added to pkg/gmredi:
1377        gmredi_k3d.F calculates the diffusivity for the Redi tensor and the eddy
1378          induced overturning streamfunction (called from gmredi_calc_tensor)
1379        gmredi_calc_eigs.F calculates the eigenvalues and eigenvectors required
1380          for use in gmredi_k3d
1381        gmredi_calc_urms.F calculates the the rms eddy velocity used to calculate
1382          the eddy diffusivity
1383    
1384    checkpoint64i (2013/06/18)
1385    o pkg/cheapaml:
1386      - take src files from MITgcm_contrib/verification_other/offline_cheapaml/code
1387        that enable the use of seaice (pkg/thsice thermo & pkg/seaice dynamics)
1388        with pkg/cheapaml.
1389    o utils/python: add subpackage for cubed sphere function, first example is
1390        simple cs.pcol to plot 2D fields on a map
1391    o pkg/streamice:
1392      - This is a new package in MITgcm, which solves dynamic equations for ice
1393         sheets and ice streams
1394      - At the moment it is independent of atmosphere/ocean dynamics, or any
1395        other physical packages in MITgcm, even ShelfIce (although it is anticipat-
1396        ed that this will change)
1397      - There is a new verification exercise that tests it, halfpipe_streamice,
1398        evolves a 40x80 km ice stream/ice shelf (at coarse resolution) in a
1399        rectangular embayment
1400      - halfpipe_streamice is forward-only for now, will have TAF test soon
1401      - for questions, email dgoldber@mit.edu
1402    o pkg/thsice:
1403      - fix filling of snow-precip diagnostic (SIsnwPrc) (left from the removing
1404        of snowPrc from common bloc, on May 2nd, thsice_step_fwd.F revision 1.40);
1405      - remove diagnostics 'SI_FrcFx' ( now identical to 'SI_Fract' with new
1406         call sequence: ice-Thermo(thsice),ice-Dyn,ice-Advect );
1407      - allow precip from pkg/cheapaml to make snow over seaice.
1408    o pkg/cfc:
1409      - move in separated header file (CFC_ATMOS.h) time-serie arrays of Atmos CFC
1410      - remove atmos CFC 2-D arrays from common bloc (now local variables)
1411      - change some hard-coded constant to run time parameter for reading and
1412        and interpolating atmospheric CFC ; keep same default as previously.
1413      - more flexible reading of Atmos CFC (number of records no longer hard-coded)
1414      - put arguments in standard order: myTime, myIter, myThid
1415      - use standard S/R GET_PERIODIC_INTERVAL for time interpolation of
1416        atmospheric CFC ; fix for the case myIter < PTRACERS_iter0.
1417      - fix calculation of surf tendencys for partial-cell and/or Non-Lin Free-Surf
1418      - new routine to print summary of CFC params and check for consistency.
1419    o pkg/seaice: add uice/vice to the parameter list of s/r seaice_advdiff,
1420      similar to thsice_advdiff.
1421      Note that for the B-grid case the routine parameters uc/vc are overwritten.
1422    o pkg/cfc:
1423      - change time interpolation for atmospheric CFC-11 (now same as for CFC-12);
1424        update output (CFC-11) of experiment cfc_example and tutorial_cfc_offline.
1425      - fix interpolation of atmphspheric CFC between Sorthern and Northern
1426        hemisphere value.
1427    o pkg/seaice:
1428      - allow to use seaice dynamics without pkg/exf (e.g., using pkg/cheapaml)
1429    o pkg/seaice: add Adams-Bashforth2 time discretization for ice dynamics;
1430                  so far only for JFNK-solver, turn on with SEAICEuseAB2 = .TRUE.
1431      - requires an additional time level that is stored in the pickup
1432      - you can start with AB2 from a pickup without this time level with
1433        pickupStrictlyMatch = .false.
1434    
1435    checkpoint64h (2013/05/26)
1436    o pkg/cheapaml:
1437      - replace one ()**.5 with SQRT + use temp var "cdu = tau/Du" (coare3_flux);
1438        affect machine truncation (but exp cheapAML_box still pass with 13 digits).
1439      - consistent treatment of uWind,vWind location: assume everywhere in
1440        pkg/cheapaml that they are on C-grid (@ uVel,vVel location)
1441        (Note: was already the case for Tair,Qair advection);
1442        add option (INCONSISTENT_WIND_LOCATION) to recover old results.
1443      - compute diabatic forcing only in the interior (excluding overlap regions)
1444      - fill in array "Qsw" (for short-wave heating);
1445      - add diagnostic for precip ; fill-in diagnostics for cheapAML state vars
1446        before any update (consistent with MITgcm state var diagnostics);
1447      - cheapaml_fields_load.F & cheapaml_init_varia.F : only fill outer edges if
1448        non periodic ; + adjusted for uWind,vWind (C-grid).
1449    o pkg/seaice:
1450      - remove dependence of pkg/seaice versus pkg/exf (file: pkg/pkg_depend) and
1451        add explicitly pkg/exf in experiments that currently use pkg/seaice.
1452      - allows to compile pkg/seaice without pkg/exf.
1453    o tools/OAD_support:
1454      - use a local copy (ourRWCPinBd) to ensure index ourRWCP stays within bounds
1455        of array "ourStepOf" in function rvNextAction (revolve.F90).
1456    o pkg/aim_compon_interf renamed to pkg/atm_compon_interf
1457      - change pkg name (to be used with other atmospheric physics pkg)
1458        but by-pass CVS when making the new pkg so that we keep the CVS history.
1459    o pkg/offline:
1460      - call OFFLINE_FIELDS_LOAD from pkg/offline/offline_init_varia.F
1461        (previously called from pkg/dic_surfforcing_init.F)
1462    o model/src:
1463      - re-order sequence of calls within packages_init_variables.F, using
1464        standard order, except for:
1465         DIAGNOSTICS_INIT_VARIA and OFFLINE_INIT_VARIA (called @ the top),
1466         CTRL_MAP_INI and OBCS_INIT_VARIABLES (called @ the bottom)
1467    o new pkg: atm_phys
1468      - add entry point and source code (previously in contrib
1469          verification_other/atm_gray/code_gray/) for new pkg "atm_phys"
1470        (atmospheric physics pkg from P. O'Gorman and T. Schneider, JCl, 2008).
1471      - re-order sequence of calls within packages_readparms.F,
1472         packages_init_fixed.F and packages_write_pickup.F
1473        (but skip packages_init_variables.F because of TAF issues).
1474      - update contrib/*/atm_gray/ experiment.
1475    o pkg/seaice (ITD code):
1476      - simplify and fix the writing of pickup-files for ITD case
1477    o pkg/seaice (ITD code):
1478      - introduce floe size dependent lateral melt for ITD case;
1479      - cleaning (avoid division by zero, change to f77 syntax, remove tabs)
1480      - update seaice_itd experiment main output.
1481    o pkg/thsice:
1482      - remove snowPrc from common block THSICE_FLUX, in THSICE_VARS.h and
1483        declared it locally (without bi,bj) in thsice_main.F & aim_do_physics.F;
1484        changed accordingly pkg/atm2d.
1485    
1486    checkpoint64g (2013/05/01)
1487    o pkg/exf ALLOW_RUNOFTEMP
1488      - if defined,  river and glacier runoff temperature can be read-in from
1489        runoftempfile; runoftempfile needs to have same format as runofffile
1490    o pkg/thsice (& pkg/bulk_force):
1491      - In case Energy-Reference-Level (ERL) is used (temp_EvPrRn=0), account
1492        for energy content of Precip + RunOff & Evap (like with pkg/exf).
1493      - change computation domain to always be the interior (without overlap).
1494      - fix bug (wrong overlap) when using EXF and stressReduction > 0.
1495    o verification/tutorial_global_oce_biogeo:
1496      - add preliminary OpenAD setup (still has problems)
1497    o pkg/seaice:
1498      - turn some parameters for choosing the convergence criterion of
1499        the inexact Newton method (JFNK) into runtime parameters for convenience
1500      - clean up seaice_calc_viscosities.F: remove/retire two options for
1501        SEAICetaZmethod (1,2), introduce area weighting for method 3; this changes
1502        the results of lab_sea/input because a division has been replaced by
1503        a multiplication with the reciprocal (sumNorm)
1504      - modify offline_exf_seaice/input.dyn_jfnk/data.seaice to improve
1505        convergence of solver (changes results, of course), and to test some
1506        new features
1507    o model/src:
1508      - remove unused (since Aug 2006) S/R SET_WRITE_GLOBAL_PICKUP and its call.
1509      - remove unused forcing field "dQdT" and associated parameter "dQdTFile".
1510      - move forcing adjustment (balancing surface forcing) in specific S/R
1511        where might also be applied exchanges (if needed) to forcing arrays.
1512    o pkg/shelfice:
1513      - allow to specify the Ice-Shelf mass per unit area (instead of
1514        shelficeLoadAnomaly) and do the conversion from one to the other
1515      - move loading from file of shelficeLoadAnomaly from SHELFICE_INIT_VARIA
1516        to SHELFICE_INIT_FIXED: (a) avoid some TAF recompution issues and
1517        (b) will be loaded in time (before calling INI_PRESSURE) in case it is
1518        needed in phi0surf for initial pressure calculation when useDynP_inEos_Zc
1519      - update isomip experiment forward output (get machine truncation error
1520        from conversion shelficeLoadAnomaly -> shelficeMass -> shelficeLoadAnomaly)
1521    o verification/offline_exf_seaice:
1522      revise data.seaice in input.thermo and input_ad and update results accordingly
1523        HO = 0.2, SEAICE_areaLossFormula = 2,
1524        SEAICE_growMeltByConv = .TRUE.,
1525        SEAICE_doOpenWaterMelt = .TRUE.,
1526      Improve consistency with input.thsice and fix the spurious 500m ice corners
1527    o verification/global_ocean.cs32x15:
1528      - set Energy Reference Level to liq. water @ 0 degC: temp_EvPrRn=0.,
1529        in icedyn (thsice+seaice-dyn) test and update output.
1530    o verification/offline_exf_seaice:
1531      - adjust list of tested variables (with testreport) and update
1532        standard test output with better slection of monitored fields.
1533    o pkg/cd_code:
1534      - swtich off Adams-Bashforth on the 1rst iteration. Update output of
1535        experiment lab_sea.hb87
1536    o tools/genmake2:
1537      - change default makedepend from the system default to tools/xmakedepend:
1538        When no makedepend is specified, select tools/xmakedepend it the test pass,
1539        otherwise select the system default (if exist and pass the test) or
1540        try to build cyrus-makedepend ; stop if none of the 3 works.
1541    o pkg/exf & pkg/thsice:
1542      - In case Energy-Reference-Level (ERL) is used (temp_EvPrRn=0), account
1543        for energy content of Precip + RunOff & Evap. Assumes:
1544       1) Rain has same temp as Air.
1545       2) Snow has no heat capacity (consistent with seaice & thsice pkgs)
1546       3) Run-Off comes at the temp of surface water (with same Cp)
1547       4) Evap over ocean is released to the Atmos @ surf-temp (=SST); should be
1548        put directly into Latent Heat flux & should use water-vapor heat capacity.
1549       5) Evap over snow/seaice (pkg/thsice) assumes constant Lf+Lv (consistent
1550        with snow having no Cp) => water vapor is released to Atmos @ 0^oC (=ERL).
1551    o pkg/seaice: simplify the use of CPP flags in JFNK-related files
1552        (compile when SEAICE_ALLOW_JFNK is defined)
1553    o pkg/thsice:
1554      - fix oceanic flux diagnostics & timeave (left from new sequence of calls
1555        implementation): move THSICE_AVE call after the advection (called directly
1556        from thsice_do_advect.F).
1557    o verification/global_ocean.90x40x15 and OpenAD:
1558      New experiment for OpenAD is identical to the one in input_ad except that
1559        multiDimAdvection=.FALSE.,
1560      There is still an issue with this.
1561    o pkg/thsice:
1562      - account for ice velocity (ocean relative velocity) in turbulent heat flux
1563        at the base of the ice; update output of global_ocean.cs32x15 (icedyn)
1564        and offline_exf_seaice (main test).
1565    
1566    checkpoint64f (2013/03/31)
1567    o verification/OpenAD:
1568      - new (smaller, without OAD_DEBUG) output_oadm.txt generated using gfortran.
1569    o verification/isomip, pkg/shelfice and OpenAD:
1570      - add OpenAD setup to this exp and make shelfice package work with OpenAD
1571    o verification/tutorial_global_oce_biogeo:
1572      - update AD and TLM output after turning off ALLOW_FE (in DIC_OPTIONS.h)
1573    o verification/offline_exf_seaice:
1574      - replace adjoint experiment (now similar to fwd input.thermo/ setup).
1575    o verification/tutorial_tracer_adjsens, pkg/ptracers and OpenAD:
1576      - add OpenAD setup to this exp and make ptracers package work with OpenAD
1577    o pkg/seaice/seaice_evp.F:
1578       mask the asymmetric contribution of the ice-ocean stress (when
1579       the turningAngle is non-zero) over open water to avoid stripes
1580       in the EVP-solutions after many EVP-substeps. This does not change
1581       the verification experiment (because turningAngle=0 in that experiment),
1582       but will affect other EVP solutions with turningAngle.ne.0
1583    o verification, AD & TLM output:
1584      - new TAF version 2.3.10 (previously 2.3.8) add more parenthesis in multiple
1585        additions and multiplications which affect results at machine truncation
1586        level. Update few AD output (1D_ocean_ice_column, bottom_ctrl_5x5,
1587        lab_sea.noseaicedyn & offline_exf_seaice) and TLM output
1588        (1D_ocean_ice_column & tutorial_tracer_adjsens.som81) which had only 12
1589        digits of matching.
1590    o pkg/seaice:
1591       modify lsr-algorithm so that it vectorizes AND converges by using a
1592       "zebra" method: split vector loop into two with step size 2; this
1593       solves a general convergence problem for the JFNK solver on a vector
1594       computer. It has the potential to even improve convergence for
1595       non-vector machines, but it does change the results so it is turned
1596       off by default. To turn on define CPP-flags SEAICE_VECTORIZE_LSR and
1597       SEAICE_VECTORIZE_LSR_ZEBRA in SEAICE_OPTIONS.h
1598    
1599    checkpoint64e (2013/03/05)
1600    o pkg/ecco and several verification experiments:
1601       Remove special versions of the_model_main.F, the_main_loop.F, forward_step.F
1602       from ecco package, and revert to unified routine in model/src/
1603       Adjust verification experiments accordingly, especially gloal_oce_llc90
1604       Should conclude long-standing work by Gael to reconsile the_main_loop with
1605       ECCO and will enable OpenAD's revolve loop in ECCO setup.
1606    o pkg/generic_advdiff:
1607      - implement compressible flow method for multi-dim advection (similar to
1608        gad_som_advect.F); add new option "GAD_MULTIDIM_COMPRESSIBLE" (since
1609        TAF generates many recomputations) to use it; no yet coded with implicit
1610        vertical advection.
1611      - change experiment advect_cs (new output) and advect_xy (same output)
1612        to test compressible flow multi-dim advection.
1613    o pkg/generic_advdiff:
1614      - fix SOM advection for unusual cases (linear Free-Surf in r*, other
1615        cases where linear Free-Surf is not @ k=1, e.g., useShelfIce)
1616    o pkg/seaice:
1617      - fix bug in the no-slip implementation in seaice_calc_strainrates.F, this
1618        bug affects two verification experiments (lab_sea and lab_sea.hb87),
1619        recover old (wrong) results by setting noSlipFac = 2. in
1620        seaice_calc_strainrates.F;
1621      - add another averaging method for etaZ (etaZmethod=3), a mix of 2 and 0
1622      - add runtime parameter SEAICE_JFNKepsilon for that finite difference
1623        gradient in the Jacobian times vector operation (s/r seaice_jacvec)
1624      - fix line search in seaice_jfnk.F (s/r seaice_jfnk_update)
1625    o pkg/seaice: reorganize seaice_lsr.F to be able to reuse more code:
1626      - new subroutines seaice_lsr_tridiagu/v
1627      - introduce loop bounds i/jmin/max to be able to use a restricted
1628        additive Schwarz method, but not used for now.
1629      - rename SEAICE_CALC_LSR_COEFFS into SEAICE_LSR_CALC_COEFFS
1630      - use new subroutines seaice_lsr_tridiagu/v in s/r seaice_preconditioner
1631    o OpenAD support
1632       Reorganize S/R call for overall time-stepping loop to facilitate
1633       OpenAD revolve loop replacement
1634       (new S/R main_do_loop.F)
1635    o model/src:
1636      - add 3-D array 3rd dimension to argument list of S/R ADAMS_BASHFORTH2/3;
1637      - pkg/cheapaml: remove local S/R ADAMS2d and use instead standard S/R
1638        ADAMS_BASHFORTH2.
1639    o pkg/cheapaml:
1640      - add new parameter (default=F, same as before) to disable full domain
1641        (including land) periodicity in X & Y dir.
1642      - new S/R CHEAPAML_COPY_EDGES to copy relaxation field into edges of
1643        prognostics field ; merge the 2 S/R cycle_2d_tracer and timestep_2d_tracer
1644        into single S/R CHEAPAML_TIMESTEP.
1645    
1646    checkpoint64d (2013/02/17)
1647    o pkg/monitor (angular momentum):
1648      - do not add Eta contribution to the total AM if using rigid-lid;
1649      - correct for Adams-Bashforth in zonal-wind part (instead of in AM_eta).
1650      - horizontal discretisation: compute Zonal wind contribution separately for
1651        each component (instead of from cell centered averaged) and use the 4
1652        grid-cell corner averaged value of Omega*(R*cos_Phi)^2 in AM_eta part.
1653      - Check that AM is conserved with linear dynamics (momAdvection=F and linear
1654        FreeSurf) if using vectorInvariant momentum.
1655    o model/src (horizontal grid):
1656      - move initialisation of all horizontal grid arrays to null value
1657        from specific horizontal grid S/R to main S/R INI_GRID;
1658      - add 2 new arrays to project model C-grid velocity on to zonal direction
1659        (similar to AngleCosC & -AngleSinC but at U and V point location) and
1660        compute them in S/R CALC_GRID_ANGLES.
1661    o pkg/seaice: replace a hard coded parameter by a runtime parameter
1662        SEAICE_JFNK_tolIter
1663    o pkg/seaice: introduce a restricted additive Schwarz (RAS) method in
1664        preconditioner for JFNK (run LSR into the overlaps as far as possible,
1665        i.e OLx/y-2, but overwrite the solution in the overlaps)
1666      - extend loop range in seaice_calc_viscosity
1667      - add new parameters SEAICE_OLx/y (default = OLx/y-2)
1668      - add flexible loop ranges to seaice_preconditioner, seaice_calc_lsr_coeffs
1669      - slightly modify loops in tridiagonal solver lsr-preconditioner
1670      - by default remove the extra exchange in seaice_preconditioner with a
1671        replacement of an undocumented CPP flag by SEAICE_PRECOND_EXTRA_EXCHANGE
1672      - modify offline_exf_seaice so that old results without RAS are reproduced
1673        for output.dyn_jfnk.txt
1674      in seaice_fgmres.F (unrelated to RAS)
1675      - add a cpp-flag option for a re-ordered mapping (potentially more
1676        efficient), but because this changes the results, turn it off by
1677        default
1678      - replace the save statement by local common blocks
1679    o utils/matlab:
1680      - fix tile-offset in rdmnc.m when output was produced using EXCH2.
1681      - update cs_grid/bk_line scripts to use load_grid.m (in utils/matlab)
1682        instead of local script "load_cs.m".
1683    o pkg/seaice:
1684      - fix a serious bug in seaice_fgmres.F, s/r seaice_scalprod, connected
1685        to the scalarProductMetric and the unrolling. By chance this does not
1686        change the verification experiment, because of the particular domain
1687        decomposition
1688    o pkg/diagnostics:
1689      - change default missing_value from UNSET_RL to -999.
1690    o pkg/layers: improve vectorization of layers_fluxcalc.F
1691      - step 1: split loops, make TatU/V 2D arrays. This alone reduces the cpu
1692        time spent in this routine by more than a factor of 3 on an NEC-SX8
1693      - step 2: replace search algorithm by a bisection algorithm found in
1694        Press et al. Numerical Recipes in Fortran. This algorithm can be
1695        vectorized and finds the correct bin in approx. log2(Nlayers) steps.
1696        For now, use this algorithm only for TARGET_NEC_SX defined.
1697      - moved the search algorithm into a separate subroutine, that is kept
1698        within the same file for automatic inlining.
1699      - modified catching potential errors
1700    o pkg/ecco:
1701      - add compile switches ALLOW_SHALLOW_ALTIMETRY and ALLOW_HIGHLAT_ALTIMETRY.
1702    o model/src, pkg/autodiff, pkg/ctrl, pkg/grdchk :
1703      - modifications for ALLOW_GENTIM2D_CONTROL
1704      -- forward_step.F, the_main_loop.F : pass options and arrays for adjoint tapes.
1705      -- load_fields_driver.F : add call to CTRL_MAP_GENTIM2D( myTime, myIter, myThid )
1706      -- add xx_gentim2d0/1 in ctrl_ad_check_lev1_dir.h checkpoint_lev1_directives.h etc
1707      -- use ctrl_swapffields.F (new) instead of exf_SwapFFields.F in ctrl_get_gen.F
1708    o model/src:
1709      - account for moist thermodynamics in (dry) potential temperature equation;
1710        update results of experiments: aim.5l_cs (x2), fizhi-cs (std + aqualev)
1711        and cpl_aim+ocn.
1712      - also switch to standard compiler (gfortran, was using ifort previously)
1713        for fizhi-cs experiments reference output.
1714    o pkg/ctrl:
1715      - 1st step toward generic time-varying control variable (2D) via CPP option
1716        ALLOW_GENTIM2D_CONTROL
1717      - note new namelist ctrl_nml_genarr in data.ctrl
1718    o verification/global_ocean.cs32x15:
1719      - switch off OLD_THSICE_CALL_SEQUENCE (both forward and AD code) to use new
1720        thsice calling sequence and update "output.icedyn.txt" output file.
1721    o pkg/ptracers:
1722      - from Ryan A.: code to allow to restart a tracer at regular time interval
1723        specifying a reset frequency and a reset-phase (for each tracers).
1724    o pkg/thsice:
1725      - implement new sequence of calls for thsice+seaice:
1726          previously:   ice-Dyn,ice-Advect,ice-Thermo(thsice)
1727          new sequence: ice-Thermo(thsice),ice-Dyn,ice-Advect
1728      - allows (with temporary CPP option "#define OLD_THSICE_CALL_SEQUENCE"
1729        in CPP_OPTIONS.h) to recover old sequence;
1730      - update diagnostics for Intermediate State thsice diagnostics: now filled
1731        just before advection (instead of just after advection in old sequence);
1732      - update output of experiment offline_exf_seaice (standard test);
1733      - in global_ocean.cs32x15 exp., postpone output.icedyn.txt update
1734        by setting #define OLD_THSICE_CALL_SEQUENCE in CPP_OPTIONS.h
1735    o pkg/aim_v23:
1736      - use tiled array for aim_CO2 and surface wind speed for export to coupler;
1737      - use standard pkg/mdsio routines to read & write CO2 pickup file;
1738      - in-line S/R AIM_AIM2DYN_EXCHANGES in aim_do_physics.F;
1739      - Implement new sequence of calls for seaice advection (with thsice and
1740        seaice diffusion): do ice advection after ice-Thermodynamic (previously
1741        was done before); change aim_do_physics.F (split the bi,bj loops block);
1742      - use same CPP option (OLD_THSICE_CALL_SEQUENCE) to recover old sequence;
1743    o pkg/thsice:
1744      - add a missing EXCH of sIceLoad in thsice_main.F (ocean set-up) for the case
1745        where just seaice diffusion is used without seaice-dynamics.
1746    
1747    checkpoint64c (2013/01/18)
1748    o pkg/seaice:
1749      - add a parameter JFNKres_tFac that can replace JFNKres_t
1750        (= JFNKres_tFac*JFNKresidual before JFNK solver)
1751      - add a line search option to the JFNK solver
1752      - move update of u/vIce and computation of initial residual into a separate
1753        routine (same file); makes the code a little easier to read (?)
1754      - the line search requires computation of the residual and for some reason
1755        I cannot do the update of u/vIce at the beginning of the Newton loop
1756        without changing the results, so we move computation of the new residual
1757        also to the end of the Newton loop, even without the line search
1758    o pkg/mdsio:
1759      - write missing value (corresponding to undefined array value) to meta files;
1760        skip this if missing value is one (UNSET_RL would be a better value for the
1761        case of undefined missing value but it's current the default missing-value);
1762        Also update mdsio_read_meta.F (reading timeInterval & missing-value).
1763    o pkg/exf & thsice:
1764      - for diagnostics purpose, fill-up and update Qsw array (+ fill the
1765        diagnostics) even when SHORTWAVE_HEATING is #undef;
1766    o verification/cfc_example:
1767      - turn on pkg/layers with pkg/diagnostics (to test pkg/layers and to
1768        illustrate how to use it).
1769    o verification/offline_exf_seaice:
1770      in input: add SEAICErestoreUnderIce=.TRUE., and reduce size of forcing
1771        files to only one time-record.
1772      in input.thermo: narrow the 2 bands of low initial ice-concentration near
1773        N & S edges; switch on SEAICErestoreUnderIce=T; use pkg/diagnostics for
1774        snapshot output; same mcPheePiston value as in thsice with
1775        surf-current=0.2m/s.
1776      in input.thsice: similar set-up as in input.thermo (channel with same seaice
1777        initial conditions).
1778    o verification/cfc_example:
1779      - update file "data" with more standard choice (default rotationPeriod,
1780        exactConserv=T, reduce ivdc_kappa to 10, remove multiDimAdvection=F,
1781        set deltaTFreeSurf to deltaTtracer) and update the output.
1782    o pkg/layers:
1783      - fix bolus part so that it compiles with #undef GM_BOLUS_ADVEC;
1784      - ensure that "layers_bolus" is switched to False when useGMRedi=False.
1785    o verification/offline_exf_seaice:
1786      - set all {field}period to zero for constant-in-time forcing (not tested
1787        anywhere else).
1788    o verification/offline_exf_seaice:
1789      - dyn_lsr  : use pkg/seaice S/R (instead of pkg/thsice) to advect sea-ice;
1790      - dyn_jfnk : use pkg/thsice S/R (instead of pkg/seaice) to advect sea-ice.
1791    o model/src:
1792      - implement Finite-Volume method for (hydrostatic) presure gradient
1793        from S.-J. Lin (QJRMS 1997), for atmosphere using sigma-coordinate.
1794    o pkg/seaice: implement EVP* by Lemieux et al. (2012).
1795      - In order to be compatible with the default EVP code, this requires changing
1796        the EVP code around a little; and because any small change immediately
1797        breaks the lab_sea.hb87 verification experiment, the reference output is
1798        updated two times (each time the remaining aggrement was only 2 digits):
1799        - after replacing 1/dt by 1*recip_dt with a precomputed recip_dt
1800        - after replacing 1/(1+0.5*dt/tau) by a/(a+1), with a=2*tau/dt
1801        The adjoint test lab_sea.evp also needed to be updated.
1802      - Turn on EVP* by setting SEAICE_deltaTevp as before, and setting
1803        SEAICEuseEVPstar=.true.; for EVP* SEAICE_deltaTevp does not need to be
1804        a factor of SEAICE_deltaTdyn, and you can set the number of EVP steps
1805        explicitly with SEAICEnEVPstarSteps (thereby overriding the default of
1806        INT(SEAICE_deltaTdyn/SEAICE_deltaTevp)). Controlling EVP* is deliberately
1807        kept obscure, because I need to test it a little more.
1808    o pkg/cheapaml:
1809      - fix few incorrect type (_RL/_RS) in subroutine calls.
1810    o pkg/seaice:
1811      - new S/R SEAICE_MAP_RS2VEC (similar to SEAICE_MAP2VEC) to map _RS arrays
1812        to _RL vector; this fixes JFNK code when compiling with "-use_r4" option.
1813    o model/src:
1814      - add a warning if using select_rStar=2 with nonlinFreeSurf <> 4;
1815        change (in input_ad*/data) select_rStar from 2 to 1 for AD verification
1816        experiments global_ocean.cs32x15 & tutorial_tracer_adjsens (+ update output)
1817    o pkg/cheapaml:
1818      - replace "273.1 _d 0" by celsius2K in pkg/cheapaml/cheapaml.F and
1819        update output of experiment cheapAML_box.
1820      - store in CHEAPAML.h coeffs ssq[0:2] for saturation specific humidity,
1821        and set them only in one place (cheapaml_readparms.F).
1822      - replace "273.16 _d 0" by celsius2K & replace "3.14159 _d 0" by constant "PI"
1823      - remove re-setting of main-model parameter "celsius2K" (in cheapaml_readparms)
1824        and re-setting of cheapAML params "lath" & "p0" (in cheapaml_init_varia).
1825    o model/src/the_main_loop.F:
1826      - fix revision 129 : need both ALLOW_ECCO and ALLOW_ECCO_EVOLUTION.
1827    o pkg/seaice:
1828      - remove legacy branch code.
1829      - retire SEAICE_GROWTH_LEGACY and SEAICE_CAP_HEFF accordingly.
1830    o verification/*/code*/SEAICE_OPTIONS.h:
1831      - remove documentation for retired CPP flags (SEAICE_GROWTH_LEGACY,
1832        SEAICE_CAP_HEFF).
1833    o pkg/cheapaml:
1834      - use standard routine (S/R GET_PERIODIC_INTERVAL) to decide when it is time
1835        to load new forcing fields.
1836      - add missing "_d 0" where it's needed; + some editing (improve indentation).
1837      - remove switch to "-r8" compiler option (no longer needed) in verification
1838        cheapAML_box, keep same output (small trucation error differences).
1839    o verification/offline_exf_seaice:
1840      - add thermodynamics only test.
1841    o verification/cheapAML_box:
1842      - split the domain in 8 (2x4) tiles; add MPI and multi-threaded test;
1843        keep same output (same 14 digits for cg2d).
1844      - switch on "-r8" compiler option (some numerical values are missing
1845        the "_d 0") and update output (only 6 digits for cg2d were preserved).
1846    
1847    checkpoint64b (2012/12/24)
1848    o pkg/cheapaml:
1849      - remove un-used variables (Qnet,EmPmR) from pickup files.
1850      - store tendency of advected variables into cheapaml pickup file
1851        and fix the AB-2 restart.
1852    o verification/offline_exf_seaice and lab_sea adjoint:
1853      - switch to new code (#undef SEAICE_GROWTH_LEGACY).
1854      - switch to 4 time steps in offline, consistent with lab_sea.
1855      - match parameters from SEAICE_GROWTH_LEGACY branch in data.seaice.
1856      - update results after change of experiment seaice.
1857    o pkg/seaice:
1858      - remove option SEAICE_MULTICATEGORY; has been replaced with run-time
1859        parameter SEAICE_multDim. Issue a warning if SEAICE_MULTICATEGORY is
1860        still defined since SEAICE_multDim needs to be set to MULTDIM value (from
1861        SEAICE_SIZE.h) to recover previous #define SEAICE_MULTICATEGORY default.
1862    o model/src:
1863      - add run-time parameter to select CG2D solver minimum-residual solution
1864        (in case of a poor convergence).
1865    o pkg/seaice/seaice_lsr.F
1866      - move calculation of matrix coefficients into new
1867        S/R SEAICE_CALC_LSR_COEFFS; for now this routine remains in the same
1868        file; the main purpose of this change is to be able to reuse the code
1869        in S/R SEAICE_PRECONDITIONER
1870      - modify the computation of the residual so that the mass of sea-ice
1871        is not used twice; this simplifies the calculations, but since
1872        the residual is never used except when LSR_mixIniGuess.ge.4---and this is
1873        not tested in testreport---this does not affect the testreport results.
1874    o verification/seaice_obcs:
1875      - disable SEAICE_GROWTH_LEGACY; reset input files to match those of
1876        verification/lab_sea/input.salt_plume; changes results/output.txt*
1877    o model/src:
1878      - adapt quasi-hydrostatic formulation to work with p or p* coordinate.
1879    o pkg/seaice:
1880      - improve description of parameters in seaice_fgmres.F and start
1881        cleaning up the code
1882      - change name of SCALPROD to SEAICE_SCALPROD and modify meaning of
1883        second argument
1884      - add a metric based on grid cell area to SEAICE_SCALPROD; update
1885        results of offline_exf_seaice.dyn_jfnk
1886      - compute initial residual norm in seaice_jfnk based on SEAICE_SCALPROD
1887    o pkg/aim_v23:
1888      - fix an other bug in dissipation heating (grid-cell area was missing).
1889    o model/src + pkg/seaice:
1890      - add global (multi-tile) linear solver for pair of tri-diagonal system
1891        along X and Y lines, respectively for U and V component.
1892        Note: 1) MPI and cube-exchange not yet coded.
1893            2) probably not accurate for poorly conditioned / large size problem.
1894      - add option for SEAICE_LSR to use global (multi-tile) tri-diagonal solver;
1895        default: not compiled and not used.
1896    o pkg/seaice:
1897      - first attempt at a multi-threaded fgmres solver for the JFNK solver:
1898        introduce bi/bj loops and use global_sum_tile_rl instead of
1899        mpi_allreduce in seaice_fgmres.F
1900      - improve diagnostics output for fgmres solver (seaice_fgmres.F)
1901      - replace a few unnecessary goto statements by if-blocks  (seaice_fgmres.F)
1902      - add a verification experiment for JFNK in offline_exf_seaice
1903    o verification:
1904      - change (for now, only fwd test) offline_exf_seaice experiment:
1905        use a re-entrant channel with idealized coastline (trapezoidal shape)
1906        at southern boundary to explore seaice dynamics and thermodynamics
1907        with simple forcing. Main set-up has dynamics+thermo and SST relaxation;
1908        secondary test (input.thsice) use thermodynamics only with SST relaxation.
1909      - add seaice-dynamics only secondary test using LSR and pkg/thsice advection.
1910    o pkg/exf:
1911      - disable "sstExtrapol" when Nr=1
1912    o verification:
1913      - add new experiment "cheapAML_box" (simple 1 layer set-up from Bruno Deremble)
1914        to test pkg/cheapaml.
1915    o pkg/aim_v23 & pkg/shap_filt:
1916      - fix dissipation heating (erroneous gravity multiplication factor).
1917    o pkg/seaice:
1918      - remove unused field pressPre from jfnk solver
1919      - rename two subroutines in seaice_preconditioner.F
1920    o eesupp/src:
1921       - S/R MDSFINDUNIT avoids reserved unit numbers (scrUnit1, eeDataUnit ...)
1922    o pkg/seaice/seaice_preconditioner.F: fix preconditioner once again
1923       - remove wrong parts of the rhs and the lhs (were in there
1924         because I did not understand the concept of this preconditioner)
1925       - add an exchange between u- and v-sweep. This increases communication
1926         by a factor of two but improves the convergence of jfnk. Ideally,
1927         one would like the u- and v-sweep to be independent. So far within
1928         undocumented ifdefs
1929       - reorganize the extra computations for printing the residuals
1930    o tools/genmake2:
1931      - comment out the "mpif.h" include in NetCDF test programm (for MPI built)
1932        since it's not necessary (and was preventing to use MNC in some cases).
1933    
1934    checkpoint64a (2012/11/16)
1935    o pkg/autodiff:
1936      - improve pkg-internal logical parameter switch (inAd/inFwd mode) so that
1937        autodiff_readparms.F no longer depends on calling order (within
1938        packages_readparms.F) and no longer requires to include ${PKG}_PARMS.h):
1939        rename param turnFreeDriftInAdMode to SEAICEuseFREEDRIFTswitchInAd
1940        and change param SEAICEuseDYNAMICSinAdMode to SEAICEuseDYNAMICSswitchInAd.
1941    o pkg/obcs:
1942      - adding tidal velocity forcing capability to obcs
1943        for usage example, see verification/seaice_obcs/input.tides
1944    o pkg/seaice:
1945      - turn the LSR-relaxation parameters WFAU/V into runtime parameters
1946        SEAICE_LSRrelaxU/V
1947      - introduce runtime parameter SEAICEetaZmethod (=0 by default)
1948    o pkg/aim_v23:
1949      - implement heating from friction (bottom friction and stratospheric drag).
1950    o pkg/shap_filt:
1951      - fix diagnostic "SHAP_dKE" (was 2 time smaller); implement heating from
1952        dissipation but only for Shap_funct=2, active when addFrictionHeating=T.
1953    o model/src:
1954      - move AddMass common block from DYNVARS.h to FFIELDS.h; allow to read-in
1955        time-constant addMass field from file (addMassFile);
1956      - support for heating due to friction (and Kinetic Energy dissipation):
1957        add option, run-time switch and 3-D field array + support code ; each pkg
1958        or S/R can add heating contribution (if there is a sink of KE); the sum is
1959        accounted for as a Temperature tendency term (EXTERNAL_FORCING_T).
1960    o pkg/seaice:
1961      - complete merge of ITD code into seaice_growth.F
1962        from MITgcm_contrib/torge/itd/code/
1963        no verification so far, but Torge Martin tested
1964        "1-D test case and Beaufort set up;
1965        deliver okay results after 1 model year."
1966      - complete merge of SEAICE_SIZE.h into all relevant routines
1967      - move computation of eta at Z-points into calc_viscosities
1968        + introduce global field etaZ
1969        + add different methods for computing etaZ, for now the old
1970          method (simple averages of eta to Z-points) is hardwired
1971        + replace etaMeanZ by etaZ in seaice_lsr, seaice_calc_residual,
1972          seaice_preconditioner
1973      - simplify computations for SEAICE_ZETA_SMOOTHREG
1974      - seaice_preconditioner:
1975        + replace one remaining press by pressLoc (mistake)
1976        + adjust printing of residuals
1977      - improve I/O of diagnostics of JFNK in seaice_jfnk.F:
1978        + add (SEAICE.h) and rename some counters (initiliased in
1979          seaice_init_fixed.F)
1980        + add _BEGIN/END_MASTER (myThid)  around print statements
1981        + print total number of iterations and failures over SEAICE_monFreq
1982          interval to STDOUT
1983      - move control over output-messages by fgmres to seaice_jfnk to save
1984        some operations
1985      - move resetting initial guess for fgmres outside of seaice_fgmres_driver
1986        in order to make restarts with sol .ne. zero (fgmres with restarts)
1987        (seaice_jfnk.F, seaice_fgmres.F)
1988      - seaice_calc_l/rhs.F: replace maskW/S by maskInW/S; this fixes
1989        a serious convergence problem when open boundaries are involved
1990    o pkg/ggl90: fix computation of control volumes for the case of
1991      ALLOW_GGL90_HORIZDIFF (probably not used very often): move control volumes
1992      up half a grid cell from C-centered to W-centered (pointed out by C. Eden)
1993    o pkg/seaice: simplify seaice_evp by avoiding use of extra fields u/vIceC
1994    o pkg/autodiff
1995      - Add inAdMode switch for SEAICEuseDYNAMICS:
1996        SEAICEuseDYNAMICSinAdMode
1997        (extend logic in ADAUTODIFF_INADMODE_SET)
1998    o pkg/seaice
1999      - Step 1 of merging ice-thickness distribution (ITD) code from
2000        MITgcm_contrib/torge/itd/ (author: Torge Martin)
2001        The code implements concept laid out in Thorndike et al. (1975);
2002        code is enabled via CPP flag SEAICE_ITD
2003        nITD (in SEAICE_SIZE.h) defines number of ice thickness categories;
2004        code is not complete yet!!
2005      - SEAICE_SIZE.h now included in almost all seaice routines
2006    o verification (using seaice):
2007      - switch back seaice-dynamics (+ lower SOLV_MAX_ITERS) in ADM exp.
2008        global_ocean.cs32x15.seaice ; update results.
2009      - compile B-grid dynamics in FW test exp 1D_ocean_ice_column ;
2010      - compile C-grid dynamics with #define SEAICE_ALLOW_JFNK in FW test exp
2011        offline_exf_seaice (previously compiling B-grid).
2012    o pkg/exf:
2013      - fix some STOP conditions in exf_check.F (from Aug 28, modifs did not allow
2014        to specify neither just 1 comp of wind or wind-stress, nor no surface momentum
2015        forcing): just replace CPP option ALLOW_ATM_WIND with run-time param useAtmWind.
2016    o pkg/layers (adjust changes from Sept 19):
2017      - do snap-shot output and fill diagnostics from inside iLa loop (layers_calc.F)
2018        this allows to remove "layers_maxNum" dimension from all layers arrays.
2019    o pkg/layers (adjust changes from Sept 19):
2020      - remove ALLOW_LAYERS_OUTPUT ; fix snap-shot and time-ave output ;
2021      - snap-shot extended to all type of layers (not just the 1rst type);
2022      - remove layers variables when corresponding CPP option is undef.
2023    o pkg/layers:
2024      - rename pkg/layers variable and add new output (layer exist & un-weighted
2025        velocity in layer)
2026    o pkg/seaice:
2027      - simplify (?) ocean-drag coefficent computations by using
2028        the same routine in all three solvers (saves some code lines)
2029      - remove global fields DRAGA and DRAGS from C-grid code and
2030        declare them locally in lsr.F (the only place where they are
2031        still used)
2032      - update AD output of lab_sea.evp (very sensitive anyway).
2033    o pkg/seaice: add Jacobian-free Newton Krylov solver for ice dynamics
2034      (Lemieux et al. 2010, 2012). Turn on with the usual SEAICE_ALLOW_JFNK
2035      and SEAICEuseJFNK=.true. A few things to note:
2036      - involves a FGMRES, that is parallel but very inefficient,
2037        because of many scalar products (global sums) in the Gram-Schmidt
2038        orthogonalization method. Needs to be replaced. Original code
2039        from J.-F. Lemieux
2040      - preconditioner for FGMRES is a stripped down version of LSOR
2041      - SOLV_MAX_ITERS is now used for LSOR as a solver and as a
2042        preconditioner. For the preconditioner, the default is set to 10.
2043      - Jacobian times vector is computed with finite differences
2044      - marginally related to JFNK-solver: add a smooth regularization for
2045        zeta with tanh that will improve convergence (Lemieux and Tremblay,
2046        2009) for any implicit solver (not implemented for EVP because EVP
2047        does not need this regularization in the first place). Define
2048        SEAICE_ZETA_SMOOTHREG in SEAICE_OPTIONS.h to use.
2049    o eesupp/src:
2050      - check in genmake2 that intrinsic S/R flush is available.
2051      - add S/R to flush IO unit (if intrinsic S/R flush is available)
2052      - flush standard & error msg unit before MPI termination
2053      - if debugMode, flush IO unit after printing msg
2054    o pkg/ctrl:
2055      - ctrl_unpack.F, ALLOW_GENARR3D_CONTROL code: fix missing argument in call
2056        to ctrl_set_unpack_xyz.
2057    
2058    checkpoint64 (2012/10/09)
2059    o pkg/shelfice
2060      - in mom_fluxform.F, mom_vecinv.F:
2061        CALL SHELFICE_V_DRAG(bi,bj,k,vFld,KE,KappaRU,vF,myThid)
2062        Bug fix KappaRU -> KappaRV
2063        does not change verification/isomip but may change other setups
2064        (presumably constant KappaRU=KappaRV)
2065      - fix diagnostics SHIU/Vdrag (thanks to Tom Millgate)
2066    o pkg/obcs:
2067      - fixed some indexing bugs in obcs_seaice_sponge.F
2068      - added obcs relaxation subroutines for HSALT and HSNOW
2069      - changes verification/seaice_obcs/results/obcs_seaice_sponge.F
2070    o pkg/seaice:
2071      - add "multicategory" parameterization for snow in analogy to ice,
2072        default is off for now.
2073    o pkg/obcs:
2074      - added obcs_seaice_sponge.F for obcs relaxation of seaice variables;
2075        see verification/seaice_obcs/input.seaiceSponge for example application.
2076      - remove local commom bloc "OBCS_GLOBAL" in obcs_readparms.F and do all the OB
2077        index setting by master-thread. This fix multi-threads Pb in previous modifs.
2078    o pkg/layers :
2079      - add diagnostics to pkg/layers
2080      - move the meat of pkg/layers from layers_calc.F to layers_fluxcalc.F
2081        (from R.Tulloch). Layers_calc.F now calls layers_fluxcalc.F accordingly.
2082    o pkg/generic_advdiff/gad_implicit_r.F :
2083      - fix ADVr diagnostics in case of both implicit vertical advection and diffusion.
2084    o pkg/seaice/seaice_growth.F:
2085      - fix SItflux diagnostics in virtual salt flux + balanceEmpmr case.
2086    o pkg/obcs:
2087      - change default setting of OBCS_UVICE_OLD from defined to undef;
2088      - use new parameter OB_indexNone for null index value (instead of hard-coded 0)
2089        in all pkg/obcs code and in other pkgs; remove k loop in obcs_check_depths.F;
2090      - pass OB_indexNone as (new) argument to S/R CTRL_MASK_SET_[X,Y]Z;
2091      - change OB null index value (OB_indexNone) to -99 ; this fix the problem
2092        with Southern & Western OB at a tile edge (at least in a simple set-up).
2093    o pkg/obcs:
2094      - change settings of OB index in case OB coincides with tile edge (shared by
2095        2 tiles), so that common OB location is registered by both tiles (instead of
2096        only 1). However, for Southern and Western OB, index value = 0 is not
2097        recognized as valid OB index (=default null value) and needs to be fixed.
2098      - modify accordingly OBCS_BALANCE_FLOW and OBCS_MONITOR (avoid double counting)
2099      - new parameter "OB_indexNone" for null index value (for now, still zero)
2100        to replace hard-coded null index value of zero.
2101    o pkg/exch2:
2102      - improve W2_USE_E2_SAFEMODE (faster) and W2_E2_DEBUG_ON:
2103        always check buffer-size (but outside the loop); move checking for valid
2104        index from W2_USE_E2_SAFEMODE to W2_E2_DEBUG_ON; in W2_E2_DEBUG_ON,
2105        print each tile and point connection only if |W2_printMsg|>= 2 and 3.
2106    o pkg/ctrl (pack & unpack):
2107      - in ctrl_pack.F & ctrl_unpack.F, use the same local file-name variable
2108        (locally defined) for different variables (+ remove the variable-specific
2109        file name in CTRL_GENARR.h). For now, only implemented for GENARR2/3D_CONTROL
2110        (to be extended to other local file names in ctrl.h).
2111    o pkg/flt:
2112      - add a FLT_Iter0 option (similar to PTRACERS_Iter0).
2113    o pkg/mdsio:
2114      - fix missing STOP in mdsio_readvec_loc.F (case ioUnit=0) when file is missing
2115    o tools/genmake2:
2116      - add similar dependences for target EXE_AD & EXE_FTL as we have for EXECUTABLE
2117        (added by Alistair in version 1.51 for building without make depend);
2118      - remove Header files list (H_SRC_FILES) from the dependence of targets
2119         ad_input_code.f & ftl_input_code.f (not clear why it was added in the first
2120        place in version 1.23): this save going through staf when unrelated header
2121        file has been modified.
2122       Note: for an intermediate target (e.g., ad_input_code.f or adtaf) without
2123        "make depend" step, still need to do "make links" before "make adtaf".
2124    o eesupp/src (+ few pkg src files) & genmake2:
2125      - finish to remove ALWAYS_USE_MPI in source code that TAF does not see;
2126      - no longer set ALWAYS_USE_MPI in Makefile (was done by genmake2).
2127      - improve genmake2 checking for ALLOW_${PKG} in CPP_OPTIONS.h files (distinguish
2128         upper/lower case ; account for space between "#" and undef/define)
2129    o pkg/flt (with exch2):
2130      - cleaning: fix so that it compiles; move remaining MPI calls out of flt_exch2.F;
2131      - simplify threads synchronisation; fix (many issues) multi-threaded with MPI.
2132    
2133    checkpoint63s (2012/09/05)
2134    o pkg/ecco:
2135      - remove #ifdef ALLOW_SMOOTH_CORREL3D brackets.
2136      - add more relevant #ifdef ALLOW_SMOOTH ones.
2137      - sort out useAtmWind, useSMOOTH, ctrlSmoothCorrel2D.
2138    o pkg/ctrl:
2139      - CTRL_OPTIONS.h : document CPPs related to smoothing; ALLOW_SMOOTH_CORREL2D/3D,
2140        ALLOW_CTRL_SMOOTH, ALLOW_SMOOTH_CTRL2D, ALLOW_SMOOTH_CTRL3D.
2141      - ctrl.h : document run time params doInitXX, doMainPack, doMainUnpack, doPackDiag,
2142        doSinglePrecTapelev (audodiff param!), ctrlSmoothCorrel2D (new) and
2143        ctrlSmoothCorrel3D (new).
2144        The added ctrlSmoothCorrel2D/3D replace the old ALLOW_SMOOTH_CORREL2D/3D CPP.
2145      - ctrl_readparms.F : initialise ctrlSmoothCorrel2D/3D and read from namelist.
2146      - ctrl_init.F ctrl_pack.F ctrl_unpack.F : switch off ustress/vstress
2147        controls when useAtmWind, and vice versa.
2148      - ctrl_map_ini_ecco.F : UVEL0, VVEL0, edtaux, edtauy cannot be smoothed as tracers.
2149      - ctrl_get_gen.F : replace #ifdef ALLOW_SMOOTH_CORREL2D with
2150          #ifdef ALLOW_SMOOTH, IF ctrlSmoothCorrel2D, IF useSMOOTH.
2151      - ctrl_map_ini_gen.F : replace #ifdef ALLOW_SMOOTH_CORREL3D with
2152          #ifdef ALLOW_SMOOTH, IF ctrlSmoothCorrel3D, IF useSMOOTH.
2153      - ctrl_set_pack_xy[z].F, ctrl_set_unpack_xy[z].F:
2154        replace ALLOW_SMOOTH_CORREL2D/3D brackets with ctrlSmoothCorrel2D/3D.
2155    o pkg/smooth:
2156      - remove un-necessary includes.
2157      - remove ALLOW_SMOOTH*D and ALLOW_SMOOTH_CORREL*D brakets.
2158        Those CPP options were never defined, and not necessary.
2159    o model/src:
2160      - fix CPP brackets in ini_mixing.F (GM_background_K belongs to gmredi).
2161      - standard treatment of useSMOOTH.
2162    o pkg/autodiff:
2163      - add LOGICAL useGGL90inAdMode, useGGL90inFwdMode, useSALT_PLUMEinAdMode,
2164        useSALT_PLUMEInFwdMode allowing to switch off ggl90 and salt_plume adjoint.
2165    o pkg/exch2:
2166      - add "if usingMPI" where it was missing (in exch2_rx?_cube*.template)
2167        + start to remove ALWAYS_USE_MPI in source code that TAF does not see.
2168      - make new S/R W2_MAP_PROCS out of w2_eeboot.F to setup exch2 CommonFlag
2169        and tiles to process mapping.
2170      - re-arrange 3 header files (W2_EXCH2_PARAMS.h, _BUFFER.h & _TOPOLOGY.h)
2171        moving /EXCH2_FILLVAL_RX/ & /W2_EXCH2_COMMFLAG/ to W2_EXCH2_TOPOLOGY.h;
2172        rename "exch2_tProc" to "W2_tileProc" and move seting of e2FillValue_RX
2173        from w2_eeboot.F to w2_readparms.F.
2174    o eesupp/src:
2175      - set exchNeedsMemsync & exchUsesBarrier according to "usingMPI" (instead of
2176        ALWAYS_USE_MPI) + moved from ini_communication_patterns.F to eeset_parms.F;
2177        also move setting of exchCollectStatistics from exch_init.F to eeset_parms.F
2178      - in eedie.F and all_proc_die.F, always call MPI_FINALIZE when ALLOW_USE_MPI
2179        is defined (remove condition on usingMPI) to match cases where MPI_INIT
2180        has been called.
2181      - fix bug I put in previous modif of exch_sm_3d_rx.template (not much used);
2182      - change default (non-MPI) value of myPid (from 1 to 0) to match MPI settings
2183        (so that on 1 proc, get same myPid independently of usingMPI)
2184      - add a stop if multi-procs but usingMPI=F ; stop also if usingMPI=T and
2185        useCubedSphereExchange with EXCH-1 (safer).
2186      - add "if usingMPI" where it was missing (+ start to remove ALWAYS_USE_MPI).
2187    o pkg/ggl90:
2188      - fix bug in filling corner mask array "mskCor" (FILL_CS_CORNER_TR_RL call)
2189        used in ALLOW_GGL90_SMOOTH code.
2190    o pkg/flt:
2191      - fix typo in FLT_WITHOUT_Y_PERIODICITY (the effect was to ignore stopping
2192        floats at the Southern end of the domain).
2193    o eesupp/inc:
2194      - add a list of CPP-options which can be set by Makefile (DEF_IN_MAKEFILE.h);
2195        but not used (and not to be used) anywhere, just for documentation.
2196    o pkg/autodiff, exf, ptracers & seaice (AD & TL output):
2197      - comment out the very nasty "writeBinaryPrec = writeStatePrec" line, since:
2198        a) can damage previously written records in any other multi-record files.
2199        b) if needed, can easily do it cleanly, by calling S/R WRITE_REC_3D_RL/S.
2200    o tools/genmake2:
2201      - define variable MAKE within Makefile and use it in place of 'make';
2202      - update AD_CONFIG.h (if needed) before building any of the executable
2203        (forward, adjoint or tangent-lin); this involves a 2nd invocation of make;
2204        and add the usual #ifndef/#define AD_CONFIG_H in AD_CONFIG.h;
2205      - always print usual warning comment 'this file is automatically generated'
2206        from script convert_cpp_cmd2defines (+ remove this warning from genmake2).
2207    o pkg/cheapaml:
2208      - updated to correspond to the code used in accepted paper (Nico Wienders).
2209    o pkg/exf:
2210        added run time switch useAtmWind to replace ALLOW_ATM_WIND cpp switch.
2211        ALLOW_ATM_WIND now just sets the useAtmWind default (see exf_readparms.F)
2212        and force defines ALLOW_BULKFORMULAE (EXF_OPTIONS.h).
2213    o pkg/exf, autodiff, ctrl, ecco and seaice:
2214        remove ALLOW_ATM_WIND brackets, or replace them with useAtmWind ones.
2215    o pkg/ctrl, ecco:
2216        allow to compile both ALLOW_U/VSTRESS_CONTROL and ALLOW_U/VWIND_CONTROL.
2217        Depending on useAtmWind, one is inactive, and the other is active (see
2218        exf_getffields.F/exf_getsurfacefluxes.F).
2219    o tools/genmake2:
2220      - improve error msg when failing in 2nd test of check_for_broken_Ff
2221      - fix option '-makefile' short-name (-mf according to genmake2 -help)
2222      - source local config file "genmake_local" just after processing the genmake2
2223        command arguments (previously done before processing arg).
2224    o pkg/grdchk:
2225      - add a call to TURNOFF_MODEL_IO for Tangent-Linear run (in this case, call
2226        to this routine from cost_final has been dropped in g_cost_final)
2227      - improve printed information (more explicit msg, no longer using "print *,"
2228         fix fcpertminus printed value).
2229    o model/src:
2230      - move call to COST_INIT_VARIA out of packages_init_variables.F directly
2231        into initialise_varia.F (just after calling PACKAGES_INIT_VARIABLES):
2232        this prevents getting cost-funct reset in adinitialise_varia recomputations.
2233    o pkg/dic:
2234      - move initialisation of "freefe" array from from dic_biotic_forcing.F to
2235        fe_chem.F: this prevents TAF from dropping this initialisation in TLM code.
2236    o pkg/grdchk:
2237      - grdchk_main.F : added CALL GLOBAL_SUM_INT( ierr , myThid )
2238      - grdchk_getadxx.F etc. : omit I/O if ierr.EQ.0
2239    o pkg/autodiff/ctrl/grdchk :
2240      - attempt to sort out what works and what does not,
2241        with regard to I/O, and to warn/stop accordingly.
2242    o pkg/grdchk:
2243      - attempt to fix grdchk in the case of useSingleCpuIO.
2244      - "if ( myProcId .EQ. grdchkwhichproc .AND. ierr .EQ. 0 )"
2245       statements were moved from grdchk_main.F and into
2246       grdchk_getadxx.F grdchk_getxx.F grdchk_setxx.F.
2247      - a global sum is applied to record numbers icvrec/layer
2248       out of grdchk_loc so that they be passed to I/O routines.
2249    o pkg/smooth:
2250      - fix recomputation that appeared with nlfs : use smooth_recip_hFacC,
2251        smooth_hFacW, smooth_hFacS (copied at init_fixed) in 3d case.
2252    o verification/testreport:
2253      - add option '-tlm' for Tangent-Linear test (-adm,-oad,-tlm are all exclusive);
2254      - can also use compressed (gzip) reference output file;
2255      - change format (in pkg/grdchk) of TLM output (+ add forward gradient)
2256        to be easier to collect by testreport.
2257      - update existing TLM output (half out-of-date by more than 3 yrs).
2258      - report NETCDF & LAPACK settings (from genmake2) in output dir.
2259      - report run-time in each individual summary (previously only for AD test);
2260        for TLM test, add also TAF version.
2261      - add daily TLM test on (old) aces cluster + weekly test on baudelaire.
2262    
2263    checkpoint63r (2012/08/15)
2264    o tools/genmake2:
2265      - fix Makefile for target ftlall (+ update files to clean after make ftlall)
2266    o pkg/ecco/ecco_cost_final.F :
2267      - fix fc print statements (to stdout and costfunction0000) so
2268        that the printed value is always after the global sum.
2269    o pkg/seaice/seaice_dynsolver.F :
2270      - fix ice strength assymptote at SEAICE_area_max<1
2271        (no change for the standard case of SEAICE_area_max=1)
2272    o some cleaning:
2273      - pkg source files: ensure that all *.F files from each pkg included the
2274        corresponding ${PKG}_OPTIONS.h file (except stand-alone src file which
2275        only includes CPP_EEOPTIONS.h); fix S/R CTRL_SMOOTH ; update AD experiment
2276        code_ad/*.F src files; add new option-file in pkg/admtlm + corresponding
2277        includes;
2278      - model/src: add PACKAGES_CONFIG.h wherever ALLOW_AUTODIFF[_TAMC] is used.
2279      - ALLOW_DIFFKR_CONTROL: add a stop in S/R CTRL_CHECK in case ALLOW_3D_DIFFKR
2280        is undef; also define /DYNVARS_DIFFKR/ common block in DYNVARS.h when
2281        ALLOW_DIFFKR_CONTROL is defined, to allow to compile and reach this stop.
2282      - update option-file CPP_OPTIONS.h of all AD experiments:
2283        * no longer include PACKAGES_CONFIG.h ;
2284        * includes ECCO_CPPOPTIONS.h if PACKAGES_CONFIG.h has been included ;
2285        * def/undef ALLOW_3D_DIFFKR independently of ALLOW_DIFFKR_CONTROL (before
2286          including ECCO_CPPOPTIONS.h).
2287    o pkg/cost, pkg/ctrl, pkg/ecco option-file:
2288      - clean-up and split content of old pkg/ecco/ECCO_CPPOPTIONS.h file into
2289        separated pkg option-file (done according to old doc from ECCO_CPPOPTIONS.h,
2290        not necessary accurate).
2291      - add a template for option-file ECCO_CPPOPTIONS.h, mostly empty, in
2292        pkg/autodiff, i.e., the 1rst pkg to compile for adjoint built, with lines to
2293        deliberately break compilation (a remainder that it needs to be customized)
2294      - in pkg/ecco, includes ECCO_OPTIONS.h instead of COST_OPTIONS.h
2295      - rename COST_CPPOPTIONS.h to COST_OPTIONS.h
2296      - rename CTRL_CPPOPTIONS.h to CTRL_OPTIONS.h
2297    o tools/genamke2:
2298      - check for lapack.
2299    o pkg/cost and pkg/ecco : attempt to sort out some of the limiting intricacies.
2300      - pkg/cost.cost_final.F : allow for use of pkg/ecco and pkg/cost cost functions
2301        jointly. The exclusive ifdefs were removed, to add costs terms (when defined)
2302        from both packages.
2303      - the fc global sum in pkg/ecco/ecco_cost_final.F was removed accordingly.
2304      - for objf_atl we use either the pkg/ecco or the pkg/cost term depending on CPPs.
2305      - pkg/ecco and model/src : add CPP brackets around pkg/cost and pkg/ctrl includes
2306        of "CTRL_SIZE.h" "ctrl.h" "ctrl_dummy.h" "optim.h" / "cost.h" accordingly.
2307    o pkg/cost : add comments to explain special and/or untested setups.
2308    o pkg/exf:
2309      - use EXF_OPTIONS.h to set pkg/exf options except if done in ECCO_CPPOPTIONS.h
2310        (previously, ALLOW_AUTODIFF_TAMC was controling this switch).
2311    o verification/*/code_ad:
2312      mimimal cleaning of AD experiments ECCO_CPPOPTIONS.h option-file:
2313      - reccord when this file is included (define ECCO_CPPOPTIONS_H)
2314      - remove the most obvious obsolete features (e.g., #define ALLOW_COST not
2315        allowed since Oct 2003 in any option-file except in PACKAGES_CONFIG.h)
2316    o pkg/seaice :
2317      - added possibility to change ice strength/PRESS0 relationship to
2318        HEFF, according to the following run time parameters
2319        SEAICEpresPow0 :: HEFF exponent for ice strength below SEAICEpresH0 (integer, >0)
2320        SEAICEpresPow1 :: HEFF exponent for ice strength above SEAICEpresH0 (integer, >0)
2321        SEAICEpresH0   :: HEFF threshold for ice strength            (m)
2322    o pkg/ggl90 :
2323      - added run time flag mxlSurfFlag to include the code that ensure
2324        mixing between first and second level (previously included as a comment)
2325    o verification/1D_ocean_ice_column/input_ad/data.autodiff :
2326      - add test of newly added dumpAdByRec=T option where
2327        we write all records to one file per variable.
2328    o verification/global_ocean.cs32x15/code_ad/CPP_OPTIONS.h :
2329      - switch to #define ALLOW_BALANCE_RELAX and ALLOW_BALANCE_FLUXES
2330        to check that this code is ok with taf and compiles in adjoint.
2331    o pkg/autodiff :
2332      - added run time param dumpAdByRec : ad dump format switch.
2333        If true then write all records to one file per variable.
2334        Else write one file per record (remains the default).
2335      - revise seaice_ad_dump.F and exf_adjoint_snapshots_ad.F accordingly.
2336    o pkg/seaice:
2337     - Added SEAICEuseTILT run time switch : if set to
2338       false then omit the tilt term in seaice dynamics.
2339     - Fix free drift calculation.
2340    o pkg/shelfice:
2341      When initializing SHELFICEDragQuadratic, set default to be
2342      consistent with shiCdrag in case SHELFICEuseGammaFrict is used,
2343      but retain option to set it independently
2344      (inconsistenty spotted by Veronique Dansereau)
2345    o eesupp/inc:
2346      - in EEPARAMS.h, add real-type constant for some frequently used simple number
2347         (0,1,2,1/2), with name explicitly referring to RS/RL type.
2348    o model/src:
2349      - move balancing of relaxation terms to new S/R balance_relax.F.
2350    o pkg/autodiff:
2351      re-write active I/O high-level (control) S/R:
2352      - rename  S/R ACTIVE_READ/WRITE_RL to ACTIVE_READ/WRITE_3D_RL
2353      - add 1 more argument (useCurrentDir) to replace the "_LOC" 2nd set of S/R.
2354      - use standard pkg/mdsio I/O routines (MDS_READ/WRITE_SEC_XZ/YZ  and
2355        MDS_READ/WRITE_FIELD); change loops to multi-threads.
2356      - update and merge active_file_control_slice.flow into active_file_control.flow
2357      - update the calls in lower level S/R (active_file.F, active_file_g.F and
2358        active_file_ad.F) keeping the argument list and function unchanged.
2359      - also update lower-level "_LOC" version (call same S/R with "useCurrentDir
2360        =.TRUE.") and remove high-level (control) _loc version (not called anymore).
2361      - new low-level active I/O routines, one for each type (RL/RS), for active var
2362        of various (XY,XZ,YZ) shape and level number (arguments: arrShape, myNr);
2363        fix ctrl_init_wet.F & ecco_cost_weights.F by calling the new S/R with the
2364        right type.
2365    o autodiff and RS=real*4:
2366      - call the right type (_RS instead of _RL) of S/R in few output S/R (pkg/exf
2367        ad-monitor and snapshots); disable arrType='RS' in mdsio_gl*.F ;
2368      - change argument type of 3-D mask argument to _RS to match type in the call
2369        (in seaice_cost*.F, ctrl_*_gen.F and *ctrl_bound.F); to be continued.
2370    o pkg/thsice:
2371      - re-anable balanceEmPmR when useSEAICE=T with useThSIce=T.
2372      - option to correct ocean fresh-water flux for imbalance of Atmos+Land
2373        fresh-water flux: uniform correction or proportional to local precip.
2374    o pkg/ctrl:
2375      - new header file CTRL_SIZE.h for parameters maxCtrlArr2D, maxCtrlArr3D
2376      - redefine CPP option ALLOW_BOTTOMDRAG_CONTROL to
2377                            ALLOW_BOTTOMDRAG_CONTROL_NONGENERIC
2378      - verification/hs94.1x64x5/ tests ALLOW_GENARR{2D,3D}_CONTROL
2379    
2380    checkpoint63q (2012/07/30)
2381    o pkg/autodiff:
2382      note about monitor and snap-shot of ad-variables:
2383      a) need to apply ADEXCH before monitor or output of ad-vars to include
2384       overlap contributions (was done for adjDump but missing for monitor).
2385      b) since ADEXCH implies adding overlap values to interior array, machine
2386       truncation error is expected when adding an ADEXCH call in the middle of
2387       the time-stepping (although mathematically identical).
2388      modifs:
2389      - fix some incorrect type (RL/RS, UV/scalar) in ADEXCH calls and ad-vars
2390        declaration (adEddyPsiX,adEddyPsiY in adcommon.h).
2391      - add new run-time params (dumpAdVarExch & mon_AdVarExch) to select how  to
2392        apply ADEXCH before monitor or snap-shot of ad-variables:
2393           =0 : no ADEXCH ; =1 : do ADEXCH ; =2 : apply ADEXCH on a local copy.
2394      - implement new method (copy+adexch) for snap-shot and monitor of main model
2395        ad-vars (initially not used by default -> output unchanged).
2396      - change default (set to 2) to use new method and update few output_adm.txt
2397        with accurate ad-monitor (global_ocean.90x40x15, tutorial_global_oce_biogeo
2398        and both tutorial_tracer_adjsens tests).
2399      - switch 2 global_ocean.cs32x15 AD-tests to AB-2 (seaice_dynmix & thsice)
2400        and turn off momDissip_In_AB in the 2 other (needed for stable AB-3).
2401    o pkg/ctrl:
2402      enable the use of a variable number (maxCtrlArr2D, maxCtrlArr3D) of
2403      generic control variables via
2404      #define ALLOW_GENARR2D_CONTROL and/or #define ALLOW_GENARR3D_CONTROL
2405      Only required customization should be S/R ctrl_map_ini_genarr.F
2406      (routine in repository contains example)
2407    o pkg/exf:
2408      - fix and refine checking of surface-relaxation setting when using EXF
2409    o verification (adjoint exp):
2410      - reduce length of simulation by half for experiment global_ocean.cs32x15
2411        (std, seaice & seaice_dynmix) and exp tutorial_dic_adjoffline; update output.
2412    o pkg/mom_common (mom_u/v_bottomdrag), pkg/shelfice (shelfice_u/v_drag)
2413      - replace if statements KE.ne.0 with KE.gt.0 to avoid sqrt of negative numbers
2414        of KE that can occur with aggressive optimization
2415      + put quadratic bottom drag calculation in separated loops (only done if
2416        using bottomDragQuadratic)
2417    o model/src: CG2D_NSA
2418      - clean-up:  stop if cg2dNormaliseRHS=T and AUTODIFF
2419         and replace GLOBAL_SUM calls with GLOBAL_SUM_TILE.
2420      - in test-exp that uses CG2D_NSA (bottom_ctrl & tutorial_tracer_adjsens),
2421         change cg2d residual target to be expressed in Wunits (=> do not normalise
2422         RHS ; this fix global_max Pb with TAF); update output.
2423    o verification/tutorial_tracer_adjsens:
2424       improve parameter consistency (and get rid of warnings):
2425       - use deltaTFreeSurf=deltaTtracer (better with NonLin FreeSurf);
2426       - switch Temp Adv Scheme from 81 to 80 (no limiter since theta < 0 is physical)
2427       - use staggerTimeStep (for stability) in som81; use default rotation period.
2428    o pkg/exch2:
2429      - with empty facet: fix compact-format (W2_mapIO=1) definition (was previously
2430        reset to 0 = 1 long line in X)
2431    o pkg/mdsio:
2432      - fix reading of dimensions from meta file for large-size domain
2433    o model/src:
2434      - fix saltIsActiveTr setting for IdealGas eosType (eosType is 6 character long);
2435      - to refine CS-grid check, add logical flag "hasWetCSCorners": true if using
2436        Cubed-Sphere Exch with CS-corners inside the domain;
2437        make new S/R INI_GLOBAL_DOMAIN from code in ini_linear_phisurf.F to calculate
2438        globalArea and to set hasWetCSCorners.
2439      - add warning if usingCurvilinearGrid and momAdvection in flux-form (missing
2440        metric terms); stop if hasWetCSCorners=T and momAdvection in flux-form.
2441      - re-activate the stop if useCDscheme and hasWetCSCorners=T (previously if
2442        useCDscheme and useCubedSphereExchange).
2443    o pkg/seaice/seaice_growth.F :
2444      - compute the SEAICE_DISABLE_HEATCONSFIX term accordingly
2445        for the (.NOT.useRealFreshWaterFlux).OR.(nonlinFreeSurf.EQ.0)
2446        when the previous code was not correct.
2447      - in all cases diagnoze the boundary condition mismatch to SIaaflux
2448      - in the case of useRealFreshWaterFlux.AND.(nonlinFreeSurf.GT.0) add
2449        that term to QNET (essentially to set the melt/freeze water to 0degC).
2450        when SEAICEheatConsFix is true, so that the ocean+ice budget heat is closed.
2451    o verification/global_ocean.cs32x15/input.seaice :
2452      - add SEAICEheatConsFix in data.seaice, ensuring closed ocean+ice heat budget.
2453      - add diagnostics (commented out) for budget test using my matlab codes (gcmfaces).
2454      - update results (output.seaice.txt) accordingly.
2455    o verification/lab_sea/input/data.seaice :
2456      - remove SEAICEheatConsFix, which is now be tested
2457        in global_ocean.cs32x15. The presently coded fix
2458        is only consistent with real fresh water + nlfs.
2459      - update results (output.txt) accordingly.
2460    o pkg/salt_plume: added diagnotic for salt tendency (oceSPtnd).
2461    o AD_CONFIG.h file:
2462      - in genmake2: remove "#undef ALLOW_ECCO_OPTIMIZATION" from AD_CONFIG.h;
2463      - remove #include "AD_CONFIG.h" from all included OPTIONS files and
2464        add it explicitly in each fortran src file where it is needed.
2465        motivation: header file AD_CONFIG.h is generated/modified after "make depend"
2466        thus introducing potentially wrong dependency; therefore, better to include
2467        it only where it's really needed, and after any other included OPTIONS file
2468        (less tempting to bring conditional includes according to ALLOW_ADJOINT_RUN
2469        or ALLOW_TANGENTLINEAR_RUN).
2470    
2471    checkpoint63p (2012/07/06)
2472    o pkg/autodiff:
2473      - rename S/R INI_AUTODIFF to AUTODIFF_INIT_VARIA ;
2474      - create new header file "AUTODIFF_PARAMS.h" for pkg/autodiff parameters
2475        which are now read from new parameter file "data.autodiff" (inAdExact
2476        previously in "data", use{KPP/GMRedi/SEAICE}inAdMode previously in data.pkg)
2477      - add file "data.autodiff" in all verification/*/input_ad/ directories.
2478      - add run-time parameter to turn On/Off SEAICEuseFREEDRIFT in adjoint/forward
2479        mode (used in global_ocean.cs32x15.seaice_dynmix test exp.)
2480    o verification/tutorial_tracer_adjsens/
2481      - add extra sub-verification which uses "SOM" advection scheme
2482        (2nd Order-Moment Advection Scheme, Prather Limiter) with
2483          #define GAD_ALLOW_TS_SOM_ADV in GAD_OPTIONS.h
2484        and in data:
2485          multiDimAdvection=.TRUE.,
2486          tempAdvScheme=81,
2487          saltAdvScheme=81,
2488    o model/src:
2489      - introduce ALLOW_BALANCE_RELAX which allow the removal
2490       of the global mean of relaxation terms by setting
2491       balanceThetaClimRelax and balanceSaltClimRelax
2492      - disable balanceEmPmR and balanceQnet in the case when useSeaice.
2493       This case is now treated appropriately in seaice_growth.F
2494    o pkg/seaice:
2495      - do balanceEmPmR and balanceQnet based on the net fluxes
2496        (SItflux) that enter the ocean+ice system rather than QNET
2497        and EMPMR. Works best in real fresh water.
2498      - SIatmFW, SIatmQnet, and SItflux computations had to be moved
2499        out of the diagnotics bloc, and stored in global arrays.
2500    
2501    checkpoint63o (2012/06/29)
2502    o vertical mixing schemes:
2503      - remove unused S/R CALC_BUOYANCY (left from branch-atmos merging)
2504      - replace computation of density (in Function STATE1, opps_calc.F) by a call
2505        to S/R FIND_RHO_SCALAR
2506      - pass sigmaR to S/R PP81_CALC, MY82_CALC (but not yet used) and to GGL90_CALC
2507        and use it for N^2 calculation in ggl90_calc.F (save 2 density computations);
2508        affects output (vermix.ggl90) at truncation level.
2509    o testreport:
2510      - change adjustment of SIZE.h for mpi+mth testing: preserve enough tiles
2511        (nSx,nSy) for the number of threads (from eedata.mth)
2512    o model/src:
2513      - remove 2nd set of calls at the top of initialise_varia.F (Adjoint part)
2514        related to Non_Lin Free-Surf or Bottom-Control (but not longer necessary).
2515  o verification/tutorial_tracer_adjsens/  o verification/tutorial_tracer_adjsens/
2516    - compile with ALLOW_CG2D_NSA    - compile with ALLOW_CG2D_NSA
2517    - run with nonlinFreeSurf=3    - run with nonlinFreeSurf=3
