4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/layers:
8      - shift potential density field "prho" by -1000 for density layer averaging so
9        that it corresponds to usual "sigma" definition (i.e., rho(p=const)-1000);
10        Note that density bin boundaries (layers_bounds in data.layers) have
11        to be set accordingly (i.e., shifted, in sigma scale).
12    o pkg/layers:
13      - fix snap-shot output of layer thickness @ V.pt and output of pot.density
14      - fix calculation of layer non-weighted velocity and layer probability
15      - add diagnostics for pot.density used for layer averaging
16    o pkg/seaice:
17      - seaice_calc_viscosity.F: change computation of deltaC**2 to ensure
18        positiveness, modify a few comments and improve variable names,
19      - the changed computation of deltaC affects most seaice-related
20        experiments at the truncation level.
21        seaice_itd.thermo is affected by far the most, with
22        only 7 digits of agreement remaining; update experiments.
23    
24    checkpoint65l (2015/05/04)
25    o pkg/shelfice:
26      - in shelfice_thermodynamics.F, if SHELFICEBoundaryLayer=.true., then set
27        factor drKp1 to zero where it is negative (ie. do not use
28        SHELFICEBoundaryLayer if hFacC>1)
29      - the same for factor drLoc in shelfice_forcing.F
30    o tools/genmake2: move FEXTRAFLAGS from FFLAGS to FOPTIM to avoid a problem
31        with modules in ptracers, when using testreport option "-small_f"
32    o pkg/seaice/seaice_growth.F (in case of SEAICE_ITD)
33      - replace tmpscal1**1.36 by faster exp(1.36*log(tmpscal1))
34    o verification/testreport
35      - add new option -small_f
36        with this option testreport first makes the target small_f (*.f files)
37        before running make (all). This is useful for explicit inlining when
38        all sources need to be full available.
39    o pkg/exf/exf_interp.F:
40        remove previous changes related to reverse (decreasing) input grids latitude
41    
42    checkpoint65k (2015/04/01)
43    o pkg/ecco:
44        fix missing cosphi initialization; use eccoiter in place of optimcycle;
45        if autodiff is not compiled then use READ_REC_XY_RL/READ_REC_XYZ_RL
46        instead of active read/write
47    o pkg/ctrl:
48        if autodiff is not compiled then use READ_REC_XY_RL/READ_REC_XYZ_RL
49        instead of active read/write.
50    o pkg/autodiff: make autodiff_readparms.F and autodiff_whtapeio_sync.F
51        return if .NOT.useAUTODIFF
52    o pkg/seaice: add CPP brackets (cost function related).
53    o model/src:
54        add useAUTODIFF run time switch.
55    o pkg/exf/exf_interp.F:
56        add code to allow input grids with latitude starting in the north (i.e. when
57        j=1 corresponds to northern edge of field); modify global_with_exf to test
58        this feature.
59    o verification/testreport:
60      - replace "grep -A3" with POSIX conformal sed command, because there are
61        implementations of grep that cannot do contextual searches
62      - replace "cat -n" by "nl" (two occurrences), because not all implementations
63        of "cat" have the option "-n"
64    o model/src:
65        add new file gsw_teos10.F that contains 3 functions, more or less a copy
66        of the gsw_toolbox.f90 of the TEOS-10 fortran interface, that are used to
67        convert from conservative to potential temperature. For now they are not
68        called anywhere.
69    o pkg/ggl90: make "useIDEMIX" useful
70      - re-organize code in s/r ggl90_calc a little to move computations that
71        are different for idemix into separate loops (changes verification
72        experiment idemix at truncation level, 12 digits remain -> updated)
73      - requires 2 new 2D fields KappaM, verticalShear
74      - make hFacI and recip_hFacI local 3D variables that are passed to
75        s/r ggl90_idemix
76      - fix and improve some comments
77    
78    checkpoint65j (2015/02/25)
79    o pkg/openad
80      - synchronize seawater.F with version in model/src: replace routine
81        body of sw_temp by calling sw_ptmp and fix/add a few comments.
82    o pkg/mnc:
83      - change default value of pickup_read/write_mnc params to FALSE
84        (since few features are missing in reading MNC pickup files).
85    o model/src:
86      - change default (background) vertical diffusivity for salt to be the
87        temperature (background) vertical diffusivity.
88      - change background vertical diffusivity in vertical mixing pkgs ggl90,
89        kl10, my82 and pp81 from temperature diffusivity to salinity diffusivity.
90        This makes ptracers default diffusivity (that uses salt diffKr) more
91        consistent with vertical mixing schemes.
92    o verification/testreport:
93      - fix typo in "-pcls" option ;
94      - put temp files in /tmp (instead of in local dir)
95      - add option "-ncad" to use genmake2 new option "-nocat4ad"
96      - allow to use "-j" option (for multi-procs make) for AD, OAD and TLM.
97    o pkg/ggl90 (idemix code):
98      - apply few fixes ; add some missing "_d 0" ; update output of exp.
99        global_ocean.90x40x15.idemix
100    o OpenAD
101      - enable active file I/O and begin removal of work-around code
102        for OpenAD for handling control variables (memory vs. active files)
103      - new CPP options file OPENAD_OPTIONS.h
104      - revert to genarr2d gradient check for hs94.1x64x5
105      - (genarr3d tested by tutorial_global_oce_biogeo, tutorial_tracer_adjsens)
106      - gentim2d works for halfpipe_streamice but not yet hs94.1x64x5
107    o tools/genmake2:
108      - add option for an alternative Makefile (from Martin) where multiple
109        source files are sent to TAF (instead of all in one file).
110    o pkg/ggl90: add IDEMIX (Olbers and Eden, 2013)
111      - code provided by Carsten Eden as an extension of ggl90
112      - so far the code is turned on within ggl90 by setting a CPP-flag at
113        compile time; a runtime flag implementation is not yet complete
114      - tested in new verification experiment global_ocean.90x40x15.idemix
115    o verification:
116      - reduce length of the AD test run by half for experiments
117        global_ocean.cs32x15 (std + thsice) and isomip
118      - enable active file I/O for OpenAD, adjust verifications accordingly
119      - halfpipe_streamice: change gradient check from genarr2d to gentim2d
120    o verification/testreport:
121      - fix two non-POSIX sed statements so that there are no error messages
122        on Mac OS X
123      - replace hostname -s with hostname | sed 's/\..*$//'
124    o model/src/seawater.F:
125      - simplify SW_TEMP to just calling SW_PTMP with P and PR exchanged
126        (following the matlab code), which would have avoided the bug caught
127        by Matt (see below) in the first place
128    o pkg/shelfice:
129      - implement alternative discretisation of quadratic drag (selectBotDragQuadr)
130        and true distance in no-slip BC (bottomVisc_pCell) similar to bottom-drag.
131      - fix sign of friction tendency (no-slip BC) and fix u,v drag for thin
132        ice-shelf case (i.e., within surface level).
133      - add config summary in shelfice_check.F
134      - remove global variable recip_SHELFICElatentHeat and replace by a local
135        variable recip_latentHeat
136      - introduce diagnostics for friction velocity uStar (in case of
137        SHELFICEuseGammaFrict)
138      - change verification experiment isomip.htd:
139        + start from pickup (as input_ad at nIter0=8640)
140        + start from SHELFICEmassFile instead of SHELFICEloadAnomaly file
141        + test SHELFICEuseGammaFrict = .TRUE.
142        + test SHELFICEadvDiffHeatFlux = .TRUE.
143    o model/src:
144      - fix bug (Thanks to Matt) in function SW_TEMP (to convert Pot.Temp to
145        in-situ Temp) and in routine SW_TEMP (in pkg/openad);
146        update output of experiments global_with_exf.yearly and isomip (all 6).
147    o pkg/shelfice:
148      - change setting of kTopC to also be zero where there is no ice-shelf.
149      - zero out surface forcing arrays (for now, for T & S + EmPmR) where
150        ice-shelf is.
151      - first attempt to get RealFreshWaterFlux effects: for now, only without
152        SHELFICEboundaryLayer ; not consistent if using synchronous time-stepping.
153    o pkg/seaice: add the option to prescribe a fixed thickness PDF
154      for thermodynamic calculations
155      - because of divisions of the type 7/7 not exactly equal to 1, this change
156        affects results of some verification experiments by up to 4 digits:
157        global_ocean.cs32x15.seaice, lab_sea, lab_sea.fd, lab_sea.salt_plume,
158        seaice_obcs, seaice_obcs.seaiceSponge, seaice_obcs.tides
159        adjoint: lab_sea, lab_sea.noseaicedyn
160        -> updated
161    
162    checkpoint65i (2015/01/23)
163    o model/src:
164      - change units of frictionHeating field from W to W/m^2
165      - fix bug in frictional heating from stratospheric drag in
166        S/R ATM_PHYS_TENDENCY_APPLY_V
167      - with synchronous time-stepping: move resetting to zero of frictionHeating
168        field from load_fields_driver.F to thermodynamics.F ;
169      - add diagnostics for frictional heating.
170    o model/src & gmredi K3D:
171      - add frictionHeating field to pickup-files (for synchronous time-stepping)
172      - move ALLOW_EDDYPSI block out of DYNVARS.h and merge it into FFIELDS.h
173      - rename uMean,vMean --> uEulerMean,vEulerMean (+ change diagnostics name
174        and name in pickup file).
175      - fix arguments of few DIAGNOSTICS_FILL calls in gmredi_k3d.F
176    o model/src:
177      - move (from ini_forcing.F) initialisation of all arrays in header file
178        FFIELDS.h into new S/R ini_ffields.F ; this fix broken restart
179        (since Nov 2012) with option selectAddFluid=1.
180    o pkg/shelfice:
181      - change units (+ document) of newly added field "shelfIceMassDynTendency"
182      - upgrade from _RS to _RL shelficeMass & shelficeLoadAnomaly arrays.
183    o pkg/obcs: re-organize obcs_calc_stevens.F to prepare for passive tracers
184    o pkg/seaice: two new runtime parameters:
185      - SEAICE_cStar replaces the hard wired "20" in the strength formulation,
186        long overdue
187      - SEAICE_tensilFac: preparation for Koenig-Beatty+Holland (2012)
188        parameterization of tensil stress for fast ice (does not do anything yet)
189    o pkg/seaice/seaice_check.F: left over from restricted addtive Schwarz method
190        for LSR: move checking overlaps out of JFNK-if-block
191    o pkg/atm_phys:
192      - move copy of grid and dynamical fields out of atm_phys_driver.F into
193        new S/R ATM_PHYS_DYN2PHYS.
194      - fix level height for Linear Free-Surf case (to be consistent with
195        fixed-in-time pressure levels).
196    o pkg/mom_common (bottomdrag):
197      - average bottomDragFld (ALLOW_BOTTOMDRAG_CONTROL) from grid-cell center
198        to correct location (U & V point) in S/R MOM_U/V_BOTTOMDRAG;
199        update output (adm & tlm) of experiment global_ocean.90x40x15.bottomdrag.
200    o pkg/shelfice (u/v_drag):
201      - add one argument (the other velocity component) to S/R SHELFICE_U/V_DRAG;
202      - use SHELFICEDragLinear & SHELFICEDragQuadratic in shelfice_v_drag.F
203        (now similar to shelfice_u_drag.F)
204      - remove condition on bottomDragTerms when calling SHELFICE_U/V_DRAG
205        from mom_vecinv.F (similar to mom_fluxform calls).
206    o pkg/mom_common (bottomdrag):
207      - add one argument (the other velocity component) to S/R MOM_U/V_BOTTOMDRAG;
208      - add options for alternative discretisation of velocity norm in quadratic
209        bottom drag: averaging of grid-cell-center KE to U.point and V.point
210        (selectBotDragQuadr=0, original code) can produce noisy patterns; this
211        improves when averaging only the other component (e.g. vVel for U bottom
212        drag) using wet-point method (selectBotDragQuadr=2) or not (=1).
213      - add options (bottomVisc_pCell) to account for partial-cell in bottom
214        friction (no-slip BC) thus getting the true distance from the bottom;
215        off by default since this also reduces model stability (explicit bottom
216        friction). Changes produce different machine truncation with linear-drag
217        + no-slip BC: update output of experiments exp4.stevens (10 digits) and
218        front_relax (bvp & mxl, 10 & 11 digits).
219    o model/src & mom pkgs:
220      - add one more level to vertical viscosity local arrays (Nr+1, previously Nr)
221        since no-slip bottom BC uses viscosity @ k+1 to update velocity @ level k
222      - for now and until vertical mixing scheme are updated to fill up level Nr+1,
223        just copy level Nr value to level Nr+1.
224    o doc:
225      - add notes form Abhisek Chakraborty on how to close Heat & Salt budgets.
226    o pkg/streamice:
227      - shelfice_init_varia.F, shelfice_init_fixed.F, shelfice_readparms.F,
228        SHELFICE.h: move array shelficemass to init_varia, initialise
229        from array shelficemassinit, which is set in init_fixed and
230        has option to be set from file; introduce array
231        shelficeMassDynTend array, set thru file in init_fixed
232      - NEW FILE: shelfice_step_icemass.F: update shelficemass from either
233        shelfIceFreshWaterFlux and shelficeMassDynTend or H_streamice in
234        pkg/streamice
235      - shelfice_thermodynamics.F: call shelfice_step_icemass if
236        SHELFICEMassStepping = .true.
237      - shelfice_ad_diff.list: add new subroutine shelfice_step_icemass.f
238    
239    checkpoint65h (2014/12/17)
240    o verification/global_ocean.90x40x15, global_ocean_ebm:
241      - update to generic controls.
242    o pkg/ctrl:
243      - ctrl_map_ini_genarr.F: test for igen>0
244      - ctrl_init_variables.F: add call to CTRL_MAP_INI_GENTIM2D.
245      - move gentim2d part of ctrl_map_ini_genarr.F to
246        new separate routine : ctrl_map_ini_gentim2d.F
247      - ctrl_cost_driver.F,ctrl_init.F ctrl_map_ini_genarr.F:
248        add time variable weights and cyclic controls (time mean,
249        seasonal cycle, etc) capabilities to gentim2d
250    o pkg/ecco:
251      - move reading of error, conversion to weights from
252        ecco_cost_init_fixed.F to ecco_toolbox.F (ecco_readwei)
253    o global_oce_llc90, cs32:
254      - activte sbo.
255      - CTRL_SIZE.h : add maxCtrlProc.
256      - activate the new genctrl capabilities.
257      - update following reorganization of global_oce_input_fields.tar.gz  
258    o pkg/ctrl/ctrl_ad_diff.list:
259      - add missing ctrl_init_rec.f
260    o tools/OAD_support/keepOriginal:
261      - add ctrl_init_rec.F
262    o model/src/the_main_loop.F, pkg/ctrl/ctrl_map_ini_genarr.F:
263      - avoid recomputations of xx_gentim2d_dummy.
264    o momentum diagnostics:
265      - move filling of diagnostics Um_Diss & Vm_Diss from mom_fluxform.F and
266        mom_vecinv.F to timestep.F (to include Smag-3D contribution).
267    o pkg/seaice/seaice_lsr.F:
268      - fix computation of BU/BV, make sure they are non-zero, only necessary
269        for cubed sphere exchanges and SEAICE_OLx/y>0.
270        This makes calling s/r fill_cs_corner_rl obsolete (removed).
271    o verification/global_ocean.cs32x15/input.seaice
272      - add test for strong implicit coupling and restricted addtive Schwarz
273        methods for LSR
274      - update results/output.seaice.txt
275    o verification/tutorial_global_oce_biogeo:
276      - AD & OAD set-up: switch off ALLOW_OLD_VIRTUALFLUX (like in fwd set-up)
277        and set PTRACERS_EvPrRn(1,2) to zero (for DIC & ALK);
278        update output_adm,_oadm,_tlm.txt
279    o pkg/dic:
280      - change default to "#undef ALLOW_OLD_VIRTUALFLUX" in DIC_OPTIONS.h
281      - add a stop when ALLOW_OLD_VIRTUALFLUX is defined and PTRACERS_EvPrRn
282        for tracer 1 & 2 is set (to avoid double counting of dilution effect).
283    o verification/tutorial_global_oce_biogeo:
284      - AD & OAD set-up: do not set PTRACERS_EvPrRn for tracer 1 & 2 since
285        dilution is already added by pkg/dic ALLOW_OLD_VIRTUALFLUX ;
286        update output_adm,_oadm,_tlm.txt
287    o eesupp/src:
288      - add fill_cs_corner_rl.F (_RL-copy of fill_cs_corner_rs.F)
289        and call it in seaice_lsr when using nonzero SEAICE_OLx/y
290    o pkg/seaice: introduce strongly implicit coupling, intended for stabilizing
291      LSR (following Hutchings et al. 2004)
292      - introduce zetaZ as a global variable (requires adjustments in
293        seaice_evp.F and seaice_jfnk.F) and compute analoguously to etaZ
294        in seaice_calc_viscosities.F
295      - new flag SEAICEuseStrImpCpl (default off)
296      - add new terms zetaZ*du/dy and zetaZ*dv/dx on both sides of the
297        momentum equations
298      - JFNK-solver (preconditioner) adjusted to allow using this method
299        (where it does not have any positive effect)
300    o pkg/seaice
301      - add overlap for restrictive additive Schwartz method also to LSR, but
302        turn it off by default (because it only seems to work for non-cubed
303        sphere/llc topologies)
304    o pkg/autodiff
305      - add extra exchanges in addummy_in_steppging also for mnc output
306    o pkg/seaice:
307      - add extra exchanges before dumping adjoint fields in seaice_ad_dump.F
308        to avoid stripes in the adjoint output (similar to addummy_in_stepping.F)
309    o pkg/obcs:
310      - add option to specify domain-connected piece Id along OB though files
311        (for now, only used to diagnose PhiVel; default =1 -> global correction)
312      - modify obcs_diag_balance.F to process each connected-part separately;
313        exclude OB where Id = 0 but keep the full divergence there (-> constant
314        Psi along this portion of OB and all inflow derived from grad(Phi))
315      - add example of OB-conect files in verification/so_box_biogeo/input.
316    o pkg/diagnostics:
317      - improve treatment of Open-Boundaries in Velocity-Potential calculation:
318      a) use non zero matrix element across OB and solve for Phi 1 grid point
319         outside OB (i.e, where tracer OBCS are applied).
320      b) global imbalance of inFlow/outFlow across OB: instead of modifying
321         velocity across OB, spread it uniformly along the OB in the RHS.
322    
323    checkpoint65g (2014/11/19)
324    o pkg/diagnostcis:
325      - add preconditioner off-diagonal factor (diagCG_pcOffDFac) as run-time param
326    o pkg/my82,pp81,kl10:
327      - fix ALLOW_3D_DIFFKR implementation (previously had no effect): use 3-D
328        field diffKr as background diffusivity to set minimum diffusivity value.
329    o pkg/seaice:
330      - add new parameter SEAICEuseEVPrev (for revisited EVP by
331        Bouillon et al 2013)
332      - add SEAICE_evpAlpha/Beta to namelist
333      - modify seaice_evp code to able to use SEAICEuseEVPrev. These changes
334        involve trivial re-ordering of divisions/multiplications that should not
335        have any effects, but ... they do change the results of lab_sea.hb87 so
336        that only 2 digits of agreement remain, in line with the general
337        instability/fragility of the evp-code. For now, I do not care and just
338        update the verification experiment
339    o pkg/ctrl : add generic pre-processing (xx_genarr2d_preproc etc)
340      - remove xx_genarr2d_numsmooth etc
341      - use xx_genarr2d_preproc etc instead
342      - carry out smooth_correl2D at initialization stage rather than during
343        time stepping.
344      - get smoothOpNb from xx_gentim2d_preproc
345    o global_oce_cs32 :
346      - add test of generic ecco capabilities.
347    o pkg/exf/exf_getsurfacefluxes.F :
348      - add to tmpUE/tmpVN rather than re-initializing them (conventional behavior).
349    o pkg/ctrl,ecco :
350      - omit un-necessary arguments to ctrl_cost_gen.F unless ECCO_CTRL_DEPRECATED
351        is defined.
352    o pkg/seaice: add diagnostics for Delta (deformation parameter)
353    o model/src:
354      - when ALLOW_3D_DIFFKR is defined, add a Warning if any of the vertical
355        diffusivity (background) is specified but ignored.
356    o verification:
357      - in testreport, convert hostname to lower case for default output dir name
358    o model, pkg : add useCTRL, useECCO parameters (on/off run time switch).
359    o pkg/dic: add modifications from Hajoon:
360      - add iron sedimentation flux function of the flux of PO4 out of bottom layer
361      - light attenuation: add self-shading effect by climatological Chlorophyll
362        (read from file).
363    o pkg/seaice/seaice_preconditioner.F : fix cpp flags, so that code also
364        compiles when SEAICE_ALLOW_DYNAMICS is undefined
365    o global_oce_llc90,cs32 : ecco_v4 verification exps now use separate
366        AUTODIFF_OPTIONS.h, CTRL_OPTIONS.h, ECCO_OPTIONS.h rather than
367        ECCO_CPPOPTIONS.h (i.e. replacing the deprecated, circumvoluted,
368        approach where CPP_OPTIONS.h includes an omnipotent
369        ECCO_CPPOPTIONS.h that superseeds pkgs '_OPTIONS.h').
370    o pkg/ctrl/ctrl_map_ini_genarr.F : include GMREDI_OPTIONS.h where
371        ALLOW_3D_KAPGM, ALLOW_3D_KAPREDI (to be added later) belong.
372    o pkg/seaice/SEAICE_SIZE.h : replace ALLOW_AUTODIFF_TAMC with ALLOW_AUTODIFF
373        to avoid needing AUTODIFF_OPTIONS.h anytime SEAICE_SIZE.h is included
374        (it seems that THSICE_SIZE.h, PTRACERS_SIZE.h have the same issue...)
375    o model/src, pkg/smooth, profiles, salt_plume, seaice, exf, ecco, ctrl :
376      add ECCO_OPTIONS.h, AUTODIFF_OPTIONS.h, CTRL_OPTIONS.h when needed
377      - ECCO_OPTIONS.h is needed when including ecco_cost.h, ecco.h
378      - AUTODIFF_OPTIONS.h is needed when including tamc.h, tamc_keys.h
379      - CTRL_OPTIONS.h is needed when including ctrl.h, optim.h, etc
380    o pkg/ctrl,ecco,exf :
381      - remove variables associated with NON-generic costs,
382        unless ECCO_CTRL_DEPRECATED is defined.
383      - remove NON-generic NON-obcs controls,
384        unless ECCO_CTRL_DEPRECATED is defined.
385    o pkg/ctrl : added ctrl_local_params.h
386    o pkg/ecco : added ecco_local_params.h
387    o verification : added ECCO_CTRL_DEPRECATED to most as and oad
388        experiments, which will progressively be removed once the
389        experiments are revised to use only generic controls/costs.
390    
391    checkpoint65f (2014/10/13)
392    o pkg/ctrl, ecco, seaice : minor changes in headers
393    o global_oce_llc90,cs32 : ecco_v4 verification exps now test generic
394        cost function and control capabilities added since checkpoint65c.
395    o pkg/ctrl: regroup all obcs ctrl variables in CTRL_OBCS.h.
396    o pkg/ecco: increase modularity and improve logic
397      - ecco_toolbox.F (new) : basic operations that are often used,
398        including ecco_zero, ecco_cp, ecco_cprsrl, ecco_diffmsk,
399        ecco_addcost, ecco_add, ecco_div, ecco_readbar.
400      - cost_gencal.F (new) : determine filnames and records.
401      - cost_genread.F, cost_generic.F : condense code using ecco_toolbox.
402      - cost_generic.F : use spzeroloc rather than hard-coded -9999,
403        and exploit the above functions leading to more compact code.
404      - cost_genread.F : rm un-necessary arguments, re-arrange args order.
405      - ecco_check.F, ecco_readparms.F : bring logic up to date (using_tpj,
406        using_ers, using_gfo, using_mdt is now only defined within gencost)
407    o pkg/ecco: extend generic cost capabilities
408      - pkg/ecco : added 3D gencost (ALLOW_GENCOST3D), added gencost
409        capabilities via gencost_preproc (+ _c,_i,_r related params),
410        gencost_posproc (+ _c,_i,_r related params), gencost_nrecperiod,
411        gencost_outputlevel arguments to cost_generic
412      - pkg/ecco/cost_genread.F (new) : interface between cost_generic
413        and active_read, making room for gencost_preproc to take effect.
414        Added preproc code ('climmon') to replace GENERIC_BAR_MONTH.
415      - pkg/ecco/cost_generic.F :
416        compute and store misfit maks*(model-data) in localdif that is
417        then used in cost and for output, output misfit if outlev.GT.0
418      - pkg/ecco/cost_averagesfields.F : depend on gencost_barskip
419        rather gencost_barfile for deciding whether to write barfile
420      - pkg/ecco/ecco_cost_driver.F : extract call to cost_profiles from cost_hyd
421      - pkg/ecco/ecco_cost_init_fixed.F : extract gencost weights from
422        ecco_cost_weights, re-activate ecco_summary, determine gencost_barskip
423      - pkg/ecco/ecco_summary.F : report gencost variables
424      - pkg/ecco/cost_gencost_customize.F : treat case of scatterometer costs
425    o pkg/sea/SEAICE_OPTIONS.h : add ALLOW_COST_ICE, ALLOW_SEAICE_COST_SMR_AREA
426    o pkg/ecco: internal re-organization
427      - resolve un-necessary dependancies within pkg/ecco and to pkg/ctrl
428        (rm includes of optim.h and ctrl.h, replace optimcycle with eccoiter,
429        mv relevant variables definition from ecco_cost.h to ecco.h,
430        make sure gencost routines only include ecco.h)
431      - throughout : add missing CCP switches, rm unused variables,
432        and rm un-necessary CPP switches
433      - throughout gencost routines : replace modelstartdate with
434        gencost_startdate when needed
435      - cost_bp_read.F : use arguments, instead of common blocs
436        so that it can be used also by (new) cost_gencost_bpv4.F
437      - ecco_init_varia.F : initialize RHOsumGlob_0, VOLsumGlob_0
438      - ecco_phys.F : compute etanFull
439      - ecco_readparms.F : rename using_topex as using_tpj, add
440        bpv4-grace to gencost list, initialize added parameters
441      - ecco_summary.F : include SIZE.h needed for augmented ecco.h
442    
443    checkpoint65e (2014/09/28)
444    o pkg/obcs:
445      - replaced the just-added CPP options with run-time variables
446        (see pkg/obcs/OBCS_PARAMS.h for details)
447    o pkg/obcs:
448      - add additional CPP options for sponge boundary layers
449        (see pkg/obcs/OBCS_OPTIONS.h for details)
450    o pkg/atm_phys:
451      - implement simple (obliquity only, assuming circular planet orbit)
452        seasonal cycle for incoming insolation ; used when run-time parameter
453        "select_incSW" is set to 1 ; by default (=0), uses old unchanged formula.
454    o pkg/exf, pkg/ecco, pkg/ctrl:
455      - add ctrlUseGen and .NOT.ctrlUseGen exclusive brackets
456      - activate gentim2d for xx_atemp,xx_aqh,xx_swdown,xx_lwdown,xx_precip
457      - implement gentim2d for xx_tauu, xx_tauv
458    o pkg/ctrl, pkg/ecco :
459      - fix and complement the generic controls implementation
460    o pkg/exf/exf_getclim.F, exf_getffields.F, exf_getsurfacefluxes.F,
461        pkg/shelfice/shelfice_thermodynamics.F,
462        verification/hs94.1x64x5/code_ad/ctrl_map_gentim2d.F,
463        verification/hs94.1x64x5/code_oad/ctrl_map_gentim2d.F :
464      - add weight in CTRL_GET_GEN calls
465    o pkg/ctrl :
466      - ctrl_get_gen.F : add weight as input parameter, and apply
467        it directly rather than using smooth_correl2Dw (to be retired).
468      - ctrl_map_gentim2d.F : add wgentim2d in CTRL_GET_GEN call
469    o pkg/ctrl :
470      - introduce run time switch ctrlUseGen (in ctrl.h, ctrl_check.F,
471        ctrl_init_variables.F, ctrl_readparms.F, ctrl_summary.F)
472      - re-activate ctrl_summary (call in ctrl_init.F)
473    o pkg/ctrl/ctrl_cost_gen.F :
474      - fix CCP brackets, remove un-necessary myiter, mytime
475    o pkg/ecco, pkg/ctrl :

477      - remove cost_forcing_gen.F (now pkg/ctrl/ctrl_cost_gen2d.F)
478      - add ctrl_cost_driver.F (replaces pkg/ecco/cost_genctrl.F)
479      - add ctrl_cost_gen2d.F (replaces pkg/ecco/cost_forcing_gen.F)
480    
481    checkpoint65d (2014/09/15)
482    o pkg/ctrl/CTRL_GENARR.h, ctrl_readparms.F :
483      - add xx_genarr2d_bounds,xx_genarr3d_bounds,
484        xx_genarr2d_numsmooth, xx_genarr3d_numsmooth
485    o pkg/ctrl/ctrl_map_ini_genarr.F :
486      - remove compilation failure
487      - replace hard coded example
488      - use ctrl_map_ini_gen2D, 3D
489    o pkg/ctrl/ctrl_pack.F, ctrl_unpack.F :
490      - on/off switch based upon xx_genarr2d_weight,3d
491    o src/packages_init_variables.F :
492      - regroup pkg/estimation calls
493      - remove CTRL_MAP_INI, CTRL_MAP_INI_ECCO
494        (moved to ctrl_init_variables)
495    o cost/cost_init_varia.F :
496      - remove ecco_cost_init_varia
497        (moved to ecco_init_varia)
498    o ctrl/ctrl_init_variables.F :

503        (moved to ctrl_init_variables)
504    o ctrl/ctrl_map_ini_ecco.F :
505      - remove ECCO_PHYS (mv to ecco_init_varia)
506      - remove seaice_ctrl_map_ini (mv to ctrl_init_variables)
507    o ecco/ecco_ad_diff.list :
508      - add ecco_init_varia.f
509    o ecco/ecco_init_varia.F
510      - new routine
511    o pkg/streamice:
512      - move call to STREAMICE_INITIALIZE_PETSC from the_model_main.F
513        to streamice_init_fixed.F ; fix setting of STREAMICEisOn.
514      - from model/src, only call pkg/streamice routines if useStreamIce is TRUE.
515    o pkg/generic_advdiff:
516      - fix bug causing negatives in GAD_SMOLARKIEWICZ_HACK, introduced 8/8/2014.
517    o pkg/exf:
518      - exf_getffields.F : add xxg_atemp, xxg_aqh, xxg_swdown, xxg_lwdown,
519         xxg_precip capability
520      - exf_wind.F : no need for ALLOW_WSPEED_CONTROL cpp switch
521    o pkg/ctrl:
522      - ctrl_pack.F, ctrl_unpack.F : omit (un)packing of undefined xx_gentim2d
523    o model/src/load_fields_driver.F :
524      - move call to CTRL_MAP_GENTIM2D ahead of BULKF_FIELDS_LOAD, EXF_GETFORCING
525        so xx_gentim2d can be applied to e.g. exf fields in a timely manner.
526    o OpenAD verification experiments:
527      - Include explicitly AUTODIFF_OPTIONS.h, COST_OPTIONS.h, and CTRL_OPTIONS.h
528        in src files (to enable to skip the ECCO_CPPOPTIONS.h);
529        for now, only in pkgs used in OpenAD verification experiments.
530      - Change all except one (halfpipe_streamice) OpenAD experiments to use pkg
531        specific option file (AUTODIFF_OPTIONS.h, COST_OPTIONS.h & CTRL_OPTIONS.h)
532        instead of using ECCO_CPPOPTIONS.h (with all relevant options in it).
533        This applies to both TAF (*/code_ad/) and OpenAD (*/code_oad/) tests.
534    o OpenAD verification tests:
535      - finish removing ALLOW_AUTODIFF_OPENAD (replaced by ALLOW_OPENAD);
536      - finish replacing ALLOW_AUTODIFF_TAMC by ALLOW_AUTODIFF (except for
537        tape/storage which are specific to TAF/TAMC) in pkgs used in OpenAD exp.
538      - leave ALLOW_AUTODIFF_TAMC undef in OpenAD verification tests (*/code_oad/)
539        and remove local copy of "tamc.h" (needed only if ALLOW_AUTODIFF_TAMC).
540    o model/src & generic_advdiff:
541      - change hard-coded loop-range in S/R APPLY_FORCING_T/S to set T & S
542        forcing over 0:sNx+1, 0:sNy=1 (instead of just 1:sNx,1:sNy): Model
543        dynamics requires valid tracer forcing only over tile interior but, for
544        some diagnostics, may need to extend it over 1 point in tile halo region.
545      - in gad_calc_rhs.F, update calls to gmredi_x/ytransport to get valid
546        tendency over i,j_Min,Max range. This allows to simplfy i,j_Min,Max
547        setting in temp/salt/ptracer_integrate.F
548    o pkg/dic:
549      - multiply tracer tendencies by maskInC (if ussing OBCS) before updating
550        gchem tracers: this allows to skip the 2nd call to OBCS_APPLY_PTRACER
551        in gchem_forcing_sep.F
552    o pkg/autodiff & obcs:
553      - add storage of current OB values for U & V (was already done for T & S).
554    
555    checkpoint65c (2014/08/30)
556    o pkg/dic:
557      - take out of dic_atmos.F the initialisation part (corresponding to istate=0)
558        and move it to new S/R DIC_INI_ATMOS ; also simplify the dependencies for
559        AD compilers (but still a Pb with multi-threading and Ajoint dependencies).
560    o verification:
561      - new experiment testing OBCS and DIC pkgs, using params & output from
562        tutorial_global_oce_biogeo but limited to a sub-domain around Drake
563        passage: take OBCS from the last year of a 2 yrs simulation and initial
564        conditions from t=1.yr while keeping the same forcing.
565    o model/src:
566      - when allowFreezing=T, only reset below freezing initial Temp to Tfreezing
567        (at any k) if checkIniTemp is not set to FALSE (default checkIniTemp=T).
568    o pkg/diagnostics (Stats-Diags):
569      - re-write S/R DIAGSTATS_CALC (more similar to TARGET_NEC_SX part) to:
570        a) refine region where stats are computed, excluding where arrhFac=0 ;
571        b) fix missing interior mask (use with OBCS) in 3-D fields statistics;
572        c) extend regional stats over the region edges (for U or V pt location).
573    o pkg/gchem:
574      - add a (2nd) call to OBCS_APPLY_PTRACER in gchem_forcing_sep.F (needed since
575        pkg/dic is currently changing/updating ptracers values beyond the OB).
576    o verification (hs94):
577      - convert Held & Suarez external_forcing.F (from hs94.cs, with Sigma-coords
578        bits) to apply_forcing.F and undef USE_OLD_EXTERNAL_FORCING in experiments
579        hs94.cs-32x32x5 and tutorial_held_suarez_cs ; also use the same version of
580        apply_forcing.F in 2D hs94 (fwd, ad & oad) but keep LatLon hs94 unchanged.
581    o pkg/ptracers:
582      - implement Adams-Bashforth on pTracers (instead of on tracer tendency),
583        switched on by setting PTRACERS_doAB_onGpTr=F (default set to doAB_onGtGs)
584      - change exp4 secondary test (input.nlfs) to test AB on T & S & pTracer
585        with AB-2 code (so that it get tested).
586    o model/src:
587      - allow to apply Adams-Bashforth on Temp & Salt (instead of on gT,gS)
588        with AB-2 code (previously only available with AB-3 code).
589        Also move the code (call to ADAMS_BASHFORTH S/R) form thermodynamics.F
590        to temp/salt_integrate.F (since the 2nd part of gt/sNm1 update is done
591        there, by calling CYCLE_AB_TRACER).
592    o pkg/generic_advdiff:
593      - change Tracer argument (drop bi,bj indices) in S/R GAD_CALC_RHS,
594        GAD_C2_ADV_R, GAD_U3_ADV_R, GAD_C4_ADV_R, GAD_DIFF_R, GAD_BIHARM_R
595        + also in GMREDI_X/Y/RTRANSPORT ; and update corresponding calls in
596        S/R temp/salt/ptracers_integrate.F
597    o model/src & pkg/ptracers:
598      - remove common block variables gT,gS (in DYNVARS.h), except when
599         USE_OLD_EXTERNAL_FORCING is defined; update TAF storage accordingly.
600      - remove common block variable gPtr.
601    o model/src & pkgs:
602      - change gTracer (and/or tracer) argument (drop bi,bj indices) in S/R
603         ADAMS_BASHFORTH(2&3), CYCLE_(AB_)TRACER, FREESURF_RESCALE_G,
604         IMPLDIFF, SOLVE_TRIDIAGONAL & _PENTADIAGONAL, GAD_SOM_ADVECT,
605         GAD_ADVECTION, GAD_CALC_RHS, GAD_IMPLICIT_R, TIMEAVE_CUMUL_DIF_1T
606      + change accordingly all calling S/R.
607      - use local temperature/salinity/ptracer tendency array (without bi,bj)
608        in S/R temp/salt/ptracers_integrate.F
609    o pkg/seaice:
610      - move computation of stress contributions to rhsU/V in s/r seaice_lsr
611        to separate s/r seaice_lsr_rhsu/v in order to be able to re-use code
612      - make u/vIceC local variables if SEAICE_CGRID is defined only to be used
613        in seaice_lsr
614      - seaice_lsr.F: make local 4D arrays UXX, VYY, etc 2D
615        in s/r seaice_lsr_calc_coeffs
616    o pkg/mdsio:
617      - in MDS_READ/WRITE_FIELD, stop if file-name (+prefix) is too long
618        (e.g., > MAX_LEN_MBUF -90 ) or, in INI_MODEL_IO, if mdsioLocalDir is
619        too long (e.g., > MAX_LEN_FNAM/2 )
620    
621    checkpoint65b (2014/08/12)
622    o pkg/matrix:
623      - pass, as argument, updated tracer field to S/R MATRIX_STORE_TENDENCY_EXP
624    o model/src:
625      - fix initialisation of geothermalFile; compile geothermal-flux code in
626        natl_box verification experiment.
627    o model/src & pkg/down_slope:
628      - push the k loop inside S/R TIMESTEP_TRACER (now called outside the k loop).
629      - in dwnslp_apply.F, update tracer tendency instead of the future tracer
630        field and call S/R DWNSLP_APPLY before TIMESTEP_TRACER; this affects
631        results at machine truncation level: update output of experiments
632        global_ocean.90x40x15.dwnslp (FWD) and lab_sea.noseaicedyn (AD).
633    o pkg/diagnostics (Stats-Diags):
634      - do not cumulate the full volume when DIAGNOSTICS_FILL is
635        called with bibjFlg < 0 (no increment of the counter for 2D/3D diag);
636        This fix the mean statistics when DIAGNOSTICS_FILL is called multiple
637        times (but Min,Max and StD are still wrong).
638    o model/src:
639      - add geothermal flux forcing: read in ini_forcing.F as time-constant
640        field "geothermalFlux" applied in S/R APPLY_FORCING_T (apply_forcing.F)
641    o model/src:
642      - move CYCLE_TRACER calls from tracers_correction_step.F to temp/salt/ptracer
643        _integrate.F so that, when leaving S/R THERMODYANMICS, theta,salt and pTrac
644        arrays are already updated while adjustments (filters, conv.adjustment) are
645        still applied later, in S/R TRACERS_CORRECTION_STEP.
646    o model/src:
647      - store in common bloc array "rhoInSitu" the virtual potential temperature
648        anomaly that is used to compute geopotential: this make the atmos code
649        more similar to ocean code which already uses rhoInSitu in calc_phi_hyd.F
650    o pkg/seaice/seaice_lsr.F
651      - rename integer variable ilcall to ipass (that's what it is called
652        in the residual diagnostics
653      - change time stepping for NPSEUDOTIMESTEP > 2 (does not change the
654        default) for improved non-linear convergence of the first few steps
655      - adjust a few comments and add new ones to explain some of the store
656        directives
657    o pkg/generic_advdiff (& ptracers):
658      - re-work the code to check for valid advection scheme and for minimum
659        size of overlap (now stored in local common bloc in gad_advscheme.F)
660    o pkg/seaice: another attempt to make the adjoint work for sea ice dynamics
661      - re-initialize more variables in seaice_lsr: u/vIceC, u/vIceNm1
662      - add an auxilliary variable "bet" and fix store directives and keys in
663        seaice_lsr_tridiagu/v, this seems to do the trick (i.e. more or
664        less exact gradients in my tests); but there are still
665        recomputation warning (although gradients are sort of OK), when
666        SEAICE_LSR_VECTORIZE is not defined, so this flag and
667        SEAICE_LSR_VECTORIZE_ZEBRA are recommended for efficiency.
668      - update verification experiments lab_sea.
669      - change some comments in S/R seaice_calc_viscosities
670    o model/src:
671      - if staggerTimeStep=T, always apply exchange to velocity field in
672        do_stagger_fields_exchanges.F instead of in do_fields_blocking_exchanges.F
673        (independent of using multi-dim advection or not); no effect on FWD run
674        but affects AD results (at machine truncation level): update output of
675        experiment 1D_ocean_ice_column (ad: 12 digits), hs94.1x64x5 (ad,oad: 13.d)
676        and isomip (oad: 12.d).
677    o pkg/generic_advdiff:
678      - stop if doAB_onGtGs is set to FALSE but ignored
679      - refine warning related to stability of tracer time-stepping
680        regarding internal wave dynamics.
681      - setting of AdamsBashforth_T,S when doAB_onGtGs=F: remove condition
682        on staggerTimeStep & implicitIntGravWave (will now get a warning
683        if potentially unstable).
684    o pkg/kl10:
685      - add new pkg "kl10" for mixing due to internal wave breaking, from
686        http://www.sciencedirect.com/science/article/pii/S1463500310000144
687        (contribution from Jody Klymak), tested in verification experiment
688        verification/internal_wave/input.kl10/
689    o isomip experiment:
690      - test pkg/shelfice with Non-Lin Free-Surf in one of the FWD set-up
691        (input.htd) and update the output.
692    o cd_code experiments:
693      - use default cd_code options (#undef CD_CODE_NO_AB_MOMENTUM &
694        #undef CD_CODE_NO_AB_CORIOLIS) in experiments: cfc_example (fwd)
695        global_ocean.90x40x15 (ad & oad) and OpenAD (ad & oad) and
696        update the corresponding output.
697    o pkg/seaice:
698      - reduce the number of include files and store directives in
699        S/R seaice_lsr_tridiagu/v
700      - change the order of loops in one case in S/R seaice_lsr_tridiagv
701        (only for SEAICE_VECTORIZE_LSR_ZEBRA defined), which allows me to
702        get rid off one store directive (a TAF bug?)
703      - add one more instance of ifdef SEAICE_VECTORIZE_LSR_ZEBRA in
704        S/R seaice_lsr_tridiagv to change the loop range for consistency
705      - remove ilcall, m from parameter list of S/R seaice_lsr_tridiagu/v
706      - fix a bug that affects the JFNK solver: replace sNx/y by i/jMax in
707        S/R seaice_lsr_tridiagu/v (requires update of
708        offline_exf_seaice/input.dyn_jfnk)
709    
710    checkpoint65a (2014/07/27)
711    o model/src:
712      - Non-Lin Free-Surf in p/z coords: allows hFacW,S to be larger than
713        surrounding hFacC=1 @ edge of a step with different kSurfC on either side
714        (topo in p-coords, ice-shelf in z-coords); update output of experiments
715        tutorial_global_oce_in_p and isomip (both AD and OpenAD output).
716    o model/src:
717      - collect momentum forcing tendency into local 2-D array (passed as argument
718        to apply_forcing S/R); this simplifies mom. Forcing diagnostics and CD_CODE
719        parts in timestep.F (without CD_CODE_NO_AB_MOMENTUM defined = the default);
720        affects results at machine truncation level (e.g., if using OBCS_SPONGE).
721      - collect T & S forcing tendency into local 2-D array (passed as argument to
722        apply_forcing S/R); add 3-D diagnostics for temp & salt forcing tendency.
723        affects results at machine truncation level (e.g., ocean: if using
724        SHORTWAVE_HEATING ; atmos: if using FrictionHeating or (atm_Rq<>0) moist
725        correction due to vertical advection).
726      - update output of experiments: fizhi-cs-32x32x40 (13 digits),
727        global_ocean.cs32x15 (fwd: icedyn, seaice, thsice, all 3 @ 11d; adm & tml:
728        seaice_dynmix & thsice, fwd grd @ 3 & 8), hs94.1x64x5 (ad grd @ 13),
729        obcs_ctrl (ad & fwd grd @ 12 & 7).
730    o pkg/ptracers & diagnostics:
731      - use ptracers (short) name (instead of long one) to make ptracers diagnostics
732        title (to avoid some unexpected truncation); sort out ptracers diags units.
733      - collect ptracer forcing tendency into local 2-D array (passed as argument
734        to apply_forcing S/R); add 3-D diagnostics for ptracers forcing tendency.
735    
736    checkpoint65 (2014/07/18)
737    o pkg/fizhi:
738      - add parenthesis around fizhi tendencies in fizhi_tendency_apply.F: this
739        affects results at machine truncation level. Update output of experiments
740        fizhi-cs-32x32x40 (12 digits for cg2d) & fizhi-cs-aqualev20 (13 digits).
741    o pkg/seaice: more clean up
742      - rename TAF common block tapes to be more consistent and remove
743        unnecessary duplicates
744      - add store directives to remove more recomputations, but use smaller
745        tapes (and adjust keys) when SEAICE_LSR_ADJOINT_ITER is undefined.
746        The idea behind this flag is to reduce the memory footprint when the
747        adjoint of the LSR is not required. As of now, defining the flag
748        SEAICE_LSR_ADJOINT_ITER increases 4 common block tapes for 2D field by
749        a factor of SOLV_MAX_FIXED (=500 by default in SEAICE_SIZE.h).
750        For experiment offline_exf_seaice, this means on a linux box with gfortran
751        nearly a factor of 10 (but keep in mind there is mostly seaice code in
752        this experiment):
753        > size mitgcmuv_ad
754        text    data        bss     dec        hex
755        5100659 1216  220458952  225560827  d71c8fb
756        5339425 1200 1868783272 1874123897 6fb4dc79 (SEAICE_LSR_ADJOINT_ITER)
757        but only a moderate increase of 36% for global_ocean.cs32x15:
758        text    data        bss     dec        hex
759        6695027 1648 1014578664 1021275339 3cdf6ccb
760        6695203 1648 1382505320 1389202171 52cd8afb (SEAICE_LSR_ADJOINT_ITER)
761      - note: there are still recomputations in global_ocean.cs32x15 and
762        offline_exf_seaice and the gradient agreement changes (gets a
763        little worse) for global_ocean.cs32x15 (-> update output_adm.seaice.txt)
764      - in general, the AD gradients still are wrong
765    o OpenAD
766      - clean up code_oad/ directories somewhat by moving files
767        dontCompile, dontTransform, keepOriginal to OAD_support/
768    o model/src:
769      - using MOM fluxform and Non-Lin Free-Surf with momDissip_In_AB=F
770        (not currently tested): add dissipation terms before NLFS rescaling of
771        tendencies (previously done after).
772    o pkg/diagnostics:
773      - write stats-diags in ascii file with more digits (same as in monitor).
774    o pkg/down_slope:
775      - drop the bi,bj dimension of argument recip_hFac in S/R DWNSLP_APPLY; with
776        NLFS (not tested), use new recip_hFac value in order to conserve tracer.
777    o model/src:
778      - new file "apply_forcing.F" containing all the code previously in
779        external_forcing.F, but with new argument list: pass, as new argument,
780        the current level tendency array to update (instead of a direct update
781        of the common bloc array). Change the corresponding calls.
782      - add CPP option USE_OLD_EXTERNAL_FORCING (default is undef) to use
783        EXTERNAL_FORCING_U,V,T,S subroutines (for backward compatibility).
784    o pkg/seaice/seaice_lsr, a little bit of clean up
785      - rearrange some code blocks, so that now all calculations for
786        setting up the right-hand-sides done within one single block
787        (I find that easier to read and understand)
788      - rearrange freedrift-code to reduce the number of ifdefs
789      - adjust some indentations and comments
790    
791    checkpoint64z (2014/07/10)
792    o model/src and several pkgs:
793      - change argument list of all S/R called from external_forcing.F and
794        called from ptracers_forcing.F (renamed to ptracers_apply_forcing.F)
795        to pass, as argument, the current level tendency array to update
796        (instead of a direct update of the common bloc array).
797      - change also (in the same way) argument list of PTRACERS_APPLY_FORCING;
798      - rename taueddy_external_forcing.f to taueddy_tendency_apply.F
799    o pkg/seaice/seaice_lsr.F
800      - always initialize local arrays in seaice_lsr_tridiagu/v
801      - add more local tapes to seaice_lsr_tridiagu/v
802      - move storing u/vice(:,:,bi,bj) out of seaice_lsr_tridiagu/v, but
803        keep it in bi/bj loop; this seems to be essential
804      - gradients are still wrong but only by 4-7 orders of magnitude
805        instead of 15 orders of magnitude, lab_sea improves a little
806    o pkg/seaice
807      - (pkg/autodiff) remove storing/restoring of seaiceMaskU/V that
808        generates unnecessary code in seaice_lsr_ad
809      - add more store directives in seaice_lsr to avoid unnecessary code
810        in seaice_lsr_ad
811      - exclude some residual computations in seaice_lsr when
812        ALLOW_AUTODIFF_TAMC is defined in order to avoid unnecessary code
813        in seaice_lsr_ad
814      - add more storing, a new tape (model/src/the_main_loop.F) and
815        another key for SEAICE_LSR_VECTORIZE_ZEBRA (the local keys ilockey
816        and klockey should be checked by a specialist)
817      - modify ( define SEAICE_VECTORIZE_LSR and SEAICE_LSR_ADJOINT_ITER )
818        and update lab_sea after previous changes in pkg/seaice below
819    o pkg/autodiff:
820      - introduce useSmoothCorrel2DinAdMode, SEAICEapproxLevInAd, and
821        viscFacInAd : run time parameters allowing for adjoint switches
822        note : logic for useSmoothCorrel2DinAdMode is in ctrl_readparms.F
823    o pkg/ecco:
824      - introduce cost_gencost_boxmean.F that computes a box mean
825        temperature (for use in adjoint sensitivity studies).
826    o model/src/set_defaults.F : initialize viscFacAdj to 1.
827    o pkg/mom_common/mom_calc_visc.F:
828      - ifdef ALLOW_AUTODIFF then include viscFacAdj factor.
829    o pkg/seaice/seaice_summary.F:
830      - statement for SEAICEadjMODE now in autodiff_readparms.F
831    o pkg/seaice:
832      - remove some store directives and add new ones in an effort to get
833        finally rid off the recomputation warnings. This is successful
834        when SEAICE_VECTORIZE_LSR ***and*** SEAICE_LSR_ADJOINT_ITER are
835        defined (i.e. no extensive recomputation warnings left), but there
836        are still too many recomputations on the solver iteration level
837      - define SEAICE_VECTORISZE_LSR in offline_exf_seaice/code_ad/SEAICE_OPTIONS.h
838      - move definition of MPSEUDOTIMESTEPS into TAMC-block in
839        SEAICE_SIZE.h
840      - add a store directive in S/R seaice_calc_viscosities
841    o pkg/seaice (ITD code):
842      - fix definition of Hlimit for multi-threaded case
843      - use double precision arithmetic to compute Hlimit: this affects results;
844        update output of experiment seaice_itd.
845    o replace content of verification/seaice_itd
846      - instead of a 1D column use the configuration of offline_exf_seaice
847        to test the ice thickness distribution code with ridging
848      - this is a first shot at this experiment
849      - change of some defaults of ridging parameters SEAICEhStar (from
850        100 to 25) and SEAICEmuRidging (from 5 to 3) in seaice_readparms.F
851        and lot of new comments.
852    
853    checkpoint64y (2014/06/20)
854    o pkg/seaice/seaice_reg_ridge.F:
855      - modify the regularization of very small volumes of ice; only check
856        total volume HEFF, and do not apply correction to individual ice
857        classes because that leads to funny patterns in the heat and fw-fluxes
858        into the ocean. Adjust seaice_itd/results/output.txt
859      - replace nITD by SEAICE_multDim in loop-ranges
860    o pkg/exf:
861      - add code to process the case field period = -12. with UV interpolation.
862      - move debug print (formerly active when exf_verbose=T) from EXF_getFFieldRec
863        into S/R that calls it (i.e., exf_set_gen.F, exf_set_uv.F & obcs_exf_load.F)
864    o verification/global_with_exf:
865      - switch all fields period to -12. (was previously untested) in input/data.exf
866        (but keep secondary test ".yearly" unchanged); update the reference output.
867    o pkg/cal:
868      - new calendar type "noLeapYear" for 365 days calendar without any leap year.
869    o pkg/exf:
870      - new integer parameter "exf_debugLev" (default set to main model debugLevel)
871        to replace logical switch "exf_verbose"
872      - report in STDOUT when loading a new record (if exf_debugLev >= 3)
873    o pkg/sbo:
874      - update from Katherine Quinn: evaluate mass directly from density and SSH
875        (budget using Finite Volume method) instead of from bottom pressure.
876      - allow testreport to collect few selected SBO output ; tested in exp.
877        global_ocean.90x40x15 (after updating the results, to include SBO output).
878      - fix some multi-threading issues (in output part).
879    o model/src & most packages:
880      - always call {PKG}_READPARMS even if corresponding use{PKG}=F;
881      - in {PKG}_READPARMS, in case use{PKG}=F: add a call to new S/R
882        PACKAGES_UNUSED_MSG to print a weak warning when parameter file
883        "data.{pkg}" exist ; and leave the S/R (return) just after.
884      - more standard LAND pkg interface (land_init_fixed.F, land_check.F).
885        + call LAND_READPARMS from packages_readparms.F
886    o pkg/seaice:
887      - remove code that resets useThSice in S/R seaice_readparms and
888        replace it by a warning in S/R seaice_check
889      - remove parameter MULTDIM, replace with nITD and runtime
890        parameter SEAICE_multDim (still hard-wired to nITD if
891        SEAICE_ITD is defined)
892    
893    checkpoint64x (2014/05/24)
894    o verification/lab_sea:
895      - update adjoint and TLM output following changes to pkg/salt_plume
896      - un-do the update after putting back local recip_Cp in few places.
897    o pkg/salt_plume: modifications by An Nguyen:
898      - add capability to do brine rejection (salt-plume) as function of
899        volume+tracers (instead of only salinity tracer).
900      - conserve volume by exchanging volume from each kLev to above to
901        accommodate in-coming brine volume
902      - store surface and klev exchanged fraction + volume in 4 new 3-d arrays
903      - switch KPP surf buoyancy due to brine forcing to 3-d
904        (3 more 3-d arrays, 2 for SPforcing[T,S], 1 for boplume)
905      - add salt_plume_volfrac, salt_plume_apply, salt_plume_tendency_apply_t
906      - unrelatedly, also add ad-hoc capability to vary salt_plume scheme
907        in East/West Arctic.
908    o pkg/sbo:
909      - incorporate modifications from Katherine Quinn to enable the use of sbo
910        pkg in ECCO-v4 set-up ; remove SBO-TimeAve output ; add monitor-like
911        output for future testreport verification (unfinished).
912    o pkg/atm_phys:
913      - change diagnostics (AtPh_Trf & AtPh_Qrf) of DARGAN_BETTSMILLER S/R:
914        skip the reseting of t_ref & q_ref to initial t & q ; this preserve the
915        output of S/R CAPECALCNEW (Parcel temp & q) for diagnostics.
916    o pkg/seaice
917      seaice_calc_ice_strength.F: modify expression to avoid divisions
918        (affects truncation)
919      seaice_do_ridging.F: clean up the insectarium
920      - fix a bug that was compensated by areaScaling (-> remove areaScaling code)
921      - added SEAICEsnowFracRidge to redistributed snow (2nd bug)
922      - set closing/openingRate to zero where no extra iteration is need (3rd bug)
923      - add some debugging information and error messages (warnings)
924    o model/src: modifications relatd to atmosphere p*:
925      - Switch to more accurate p* coordinate slope term (calc_grad_phi_hyd.F)
926      - With p* or Sigma-P, use constant reference Pot.Temp (thetaConst) instead
927        of vertical profile tRef in geopotential background and anomaly.
928      - Acount for true p* correction in theta <-> T conversion in pkg/aim_v23
929        and pkg/atm_phys.
930      - Update FWD output of experiments: aim.5l_cs (x2), fizhi-cs-32x32x40,
931        fizhi-cs-aqualev20, fizhi-gridalt-hs, tutorial_held_suarez_cs, cpl_aim+ocn.
932    o pkg/seaice: fix a bug in seaice_prepare_ridging.F, forgot a sqrt
933    o pkg/ptracers: compute ptracer source/sink due to linear free surface.
934        not used right now, but can be used in BGC packages to fix conservation.
935    o pkg/dic, pkg/gchem: move tracer_meanarea to gchem, so it can be used by
936        other packages too.
937    o pkg/seaice/seaice_calc_ice_strength.F: replace SEAICE_rhoSnow by
938        SEAICE_rhoIce in the Rothrock (1975)-type strength calculations (bug fix)
939    o model/src:
940      - since we have several heat capacity (even in model/src), define "recip_Cp"
941        as local variable (no longer in common block) to avoid any confusion.
942      - add thetaConst in PARAMS.h (to be used with pStar or sigma-P coords).
943    o pkg/exf:
944      - from Jeff Scott: add option (#define EXF_CALC_ATMRHO) to calculate local
945        air density as function of air Temp, Humidity and atm pressure.
946    
947    checkpoint64w (2014/05/02)
948    o verification:
949      - update output_adm.txt files for experiment global_ocean.cs32x15 (seaice &
950        seaice_dynmix) and lab_sea (primary test & noseaicedyn): moving/changing
951        code from seaice_growth.F & seaice_advdiff.F to new ridging routines
952        seaice_reg_ridge.F seaice_do_ridging.F affects AD gradient
953        (down to 8-7 matching digits for global_ocean and 5-6 for lab_sea).
954    o model/src: for atmosphere in p* coords:
955      - store factor rStarFacC**atm_kappa (= pStarFacK) in common block
956      - implement more accurate p* coordinate slope term (in calc_grad_phi_hyd.F),
957        but not yet activated.
958    o pkg/seaice: fix restart problem for ITD with new ice strength parameterisation:
959      - move computation of opnWtrFrac = 1-AREA to before computing ice strength
960      - this changes the results (but not for any verification experiment, because
961        none tests this), but avoids having an extra field in the restart files
962    o pkg/seaice: remove global variable TICE (not needed)
963      - replace by TICES or local variable where necessary (cost_seaice_test,
964        seaice_diagnostics_state)
965      - move copying TICE to TICES from seaice_check_pickup to seaice_read_pickup
966      - use specific read/write routines for reading and writing individual leves
967        of a multilevel field
968    o pkg/ctrl & model/inc:
969      - move additional anomaly fields of control vars (related to options:
970         ALLOW_KAPGM_CONTROL, ALLOW_KAPREDI_CONTROL and ALLOW_BOTTOMDRAG_CONTROL)
971        from DYNVARS.h into new header file: CTRL_FIELDS.h
972    o pkg/seaice: some small modifications to the ridging code
973      - make fw2ObyRidge a global variable and add the freshwater flux to
974        seaice_growth
975      - pass actual thickness from seaice_prepare_ridging, so that it is
976        computed only in one place and compute it in the same way as in
977        seaice_growth
978      - initialise more fields in seaice_do_ridging that where cause floating
979        point exceptions over land
980    o pkg/seaice: preparations for ridging code and first real ridging code
981      - move most of "PART 1" of S/R seaice_growth into a new and separate
982        S/R seaice_reg_ridge that will both regularize the state variable after
983        advection call the actual ridging routine;
984      - requires to make 5 fields global fields: d_HEFFbyNEG,d_HSNWbyNEG,
985        d_AREAbyRLX,d_HEFFbyRLX,saltFluxAdjust;
986      - remove ridging code from seaice_advdiff
987      - clean up remaining part 1 of seaice_growth in an attempt to make it
988        more readable (this is probably subjective)
989      - call seaice_itd_redist once in the initialisation phase to have the initial
990        conditions in the correct category
991      - finally: add new ridging routine for ITD code
992    
993    checkpoint64v (2014/04/11)
994    o pkg/ecco:
995      - add runtime parameters mdt[start,end]date[1,2]
996      - rename variable "tpmean" as "mdt" and "topexmeanfile" as "mdtdatfile"
997    o pkg/seaice:
998      - make deltaC a global variable, so that it can be used in ridging code
999      - first step towards ridging: introduce new routines that compute
1000        ice strength based on ridging parameters
1001      - add diagnostic for HSNOWITD
1002      - add opnWtrFrac as a global variable (required for ridging scheme)
1003    o pkg/salt_plume + pkg/seaice/seaice_growth.F
1004      - add SALT_PLUME_IN_LEADS flag to activate pkg/salt_plume only when ice
1005        AREA exceeds a threshold (code contributed by I.Fenty in 2011)
1006    o verification/hs94.1x64x5:
1007      - leave ALLOW_AUTODIFF_TAMC undefined in code_oad/AUTODIFF_OPTIONS.h
1008      - do not use ECCO_CPPOPTIONS.h anymore for TAF & OpenAD Adjoint tests.
1009    o autodiff:
1010      - Start to include explicitly AUTODIFF_OPTIONS.h, COST_OPTIONS.h,
1011        and CTRL_OPTIONS.h in src files (to enable to skip the ECCO_CPPOPTIONS.h)
1012        For now, only in pkgs used in verification/hs94.1x64x5.
1013      - Replace ALLOW_AUTODIFF_TAMC by ALLOW_AUTODIFF (except for tape/storage
1014        which are specific to TAF/TAMC).
1015      - Replace ALLOW_AUTODIFF_OPENAD by ALLOW_OPENAD:
1016        since ALLOW_OPENAD is defined in PACKAGES_CONFIG.h (any time pkg/openad
1017        is compiled), this simplifies/reduces which *_OPTIONS.h file to include.
1018      - OpenAD: change Makefile to generate the appropriate AD_CONFIG.h when
1019        building mitgcmuv_ad (make adAll).
1020    o pkg/ecco:
1021      - cost_gencost_seaicev4.F:
1022         reformulate proxy cost as function of sst and local param SEAICE_freeze
1023         change cost names from siv4-[sst,vol] to siv4-[deconc,exconc]
1024      - add stop statement if old names siv4-[sst,vol] are used
1025      - add snapshots + cost reports for atmospheric longwave
1026      - remove factor 0.1 in front of wtau[u,v]
1027      - replace never used flag ALLOW_TMI_COST_CONTRIBUTION with
1028         ALLOW_TMI_SST_COST_CONTRIBUTION
1029    o pkg/atm_phys:
1030      - add some diagnostics for Short-wave and for convection S/R.
1031    o pkg/seaice/seaice_growth:
1032      - fix a bug in the lateral melt parameterization for SEAICE_ITD
1033        in seaice_growth; tempFrz needs to be computed inside the i/j-loop
1034      - rearrange loop order for better vector code in the same code block
1035      - rewrite the floeDiameter formula to have fewer divisions
1036      -  (miraculously) none of this changes the results of seaice_itd
1037    o pkg/smooth:
1038      - move param smooth2Ddiffnbt to pkg/ecco
1039    o pkg/salt_plume:
1040      - salt_plume_frac.F:
1041         clean up local param names
1042         reformulate (1-frac) to frac; original 1-frac was based on swfrac code
1043    o pkg/rw:
1044      - add RS version of S/R READ_MFLDS_LEV.
1045    o pkg/streamice:
1046      - fix the restart test by writing/reading pickup_streamice files.
1047    o pkg/seaice:
1048      - refine checks for jfnk-related parameters
1049      - comment out if statement with SEAICEuseIMEX parameter as long as there
1050        is no IMEX code to avoid confusion and surprises
1051    
1052    checkpoint64u (2014/03/07)
1053    o verification/MLAdjust:
1054      - rename secondary test suffix:
1055         1.leith  -> A4FlxF  + switch to flux-form & add side-drag
1056         0.leithD -> AhFlxF  + switch to flux-form
1057         0.smag   -> AhVrDv  (use Vorticity-Div. visc form) + add side-drag
1058         0.leith  -> AhStTn  (use Strain-Tension visc form) + add side-drag
1059    o pkg/mom_vecinv:
1060      - remove unused arguments from S/R MOM_VI_HDISSIP & MOM_HDISSIP (as it used
1061        to be before mom_calc_visc.F)
1062      - skip the call to MOM_CALC_TENSION & MOM_CALC_STRAIN if not needed.
1063      - add 2nd copy of vort3 & strain that knows about lateral BC (free/no slip):
1064        this is simpler for the adjoint and for diagnostics.
1065    o model/src + pkg/momentum:
1066      - add input files for  2-D additional Western and Southern cell-edge wall
1067         (e.g., to add "thin-wall" where it is =1).
1068      - fix sideDrag option for thin-walls with Non-Lin Free-Surf
1069        using 2nd hFacZ that is computed from initial (fix domain) hFac
1070      - known limitations of thin wall implementation: not yet coded for sigma
1071        coords; not working with CD-scheme neither.
1072    o pkg/seaice:
1073      - rename recently introduced parameters from (wrong name) AB to
1074        BDF (backward difference time discretisation)
1075      - retire runtime parameters SEAICEuseAB2, SEAICE_abEps
1076    o tools/adjoint_options:
1077      - remove setting of "OPENAD=true" (now set by command line "genmake2 -oad")
1078    
1079    checkpoint64t (2014/02/01)
1080    o pkg/ecco
1081      - add compile flag ALLOW_GENCOST_TIMEVARY_WEIGHT in ECCO_OPTIONS.h and
1082        runtime logical flag gencost_timevaryweight to read daily sea-ice sigma
1083      - replace hard-coded record number and period which only work for monthly
1084        with read-in runtime param that works for other periods (month,day,year)
1085    o pkg/thsice
1086      - corrected store directive fixes thsice adjoint gradient checks
1087    o genmake2 & testreport:
1088      - add genmake2 option "-oad" to generate a Makefile for OpenAD built and
1089        in this case, use tools/adjoint_options/adjoint_oad as default AD optfile.
1090        Update testreport accordingly. No need to set "export OPENAD=true"
1091        in adjoint_options/adjoint_oad anymore (will be removed later).
1092    o pkg/shelfice:
1093      - put T & S shelfice forcing into model surfaceForcing_T,_S (for now,
1094        only if SHELFICEboundaryLayer=F); Change model/src/external_forcing.F
1095        so that surface forcing applies to k=kSurf if using pkg/shelfice.
1096    o pkg/ctrl, pkg/grdchk, pkg/ecco:
1097      - Changes to make GENARR more modular (i.e. invisible if not used)
1098    o model/src/temp_integrate.F and salt_integrate.F
1099      - re-include store directives that were removed on Dec 27th.
1100    o model/src/external_forcing_surf.F
1101      - add storage directives for EmPmR and PmEpR to avoid recomputation of
1102        seaice_model in the adjoint that is problematic when seaice_model is
1103        turned off in the adjoint. The resolved issue dated back to July when
1104        EXTERNAL_FORCING_SURF call was moved.
1105        Update global_ocean.cs32x15/*/output_adm.seaice_dynmix.txt accordingly.
1106    o pkg/exf/exf_check.F
1107      - fix a small bug again (originally found by Wentao Liu, now found again)
1108      - streamline error output
1109    o pkg/streamice and aim_v23:
1110      - replace a few "_EXCH_XY_RL (" with "_EXCH_XY_RL(", so that
1111        Apple's /usr/bin/cpp knows what to do:
1112        Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)
1113        Target: x86_64-apple-darwin13.0.0
1114    
1115    checkpoint64s (2014/01/05)
1116    o tools/adjoint_options:
1117      - switch to fastopt.net TAF server (instead of default fastopt.de) for
1118        AD optfiles adjoint_diva & adjoint_f95 (similar to adjoint_default).
1119    o model/src:
1120      - remove some unnecessary TAF storage directives in forward_step.F and
1121        in dynamics.F (note: not always removed by TAF, e.g., double storage
1122        of kappaRU,kappaRV in former version of dynamics.F).
1123    o model/src & pkg/ptracers:
1124      - call directly GAD_IMPLICIT_R & IMPLDIFF + DWNSLP_APPLY from temp_integrate.F
1125        salt_integrate.F and ptracers_integrate.F (instead of from thermodynamics.F)
1126        and remove ptracers_dwnslp_apply.F & ptracers_implicit.F
1127      - call MATRIX_STORE_TENDENCY_EXP for each tracer (in ptracers_integrate.F)
1128      - add fZon & fMer as output argument of S/R GAD_CALC_RHS.
1129      - update TAF AD-output of experiments global_ocean.90x40x15 (13 for AD-grad).
1130    o useSingleCpuInput separates single-CPU input from single-CPU output;
1131        for now only implemented for in exf_interp_read.F
1132    o verification/advect_xy:
1133      - fix missing EXCH call in local version of ini_salt.F and update output.
1134    o momentum diagnostics:
1135      - fix which deltaT is used in Total-Tendency diagnostics.
1136      - fix typo in diagnostics for momentum tendency from AB.
1137    o pkg/seaice/seaice_lsr.F: fix an initialisation bug for the
1138        SEAICE_VECTORIZE_LSR_ZEBRA option that lead to NaNs on a NEC-SX8
1139    
1140    checkpoint64r (2013/12/08)
1141    o verification/*/results:
1142      - Update reference output of experiments that were passing with just 13 digits
1143         (make it easier to detect future changes in results)
1144    o model/src & pkg/ptracers:
1145      - move calls to GAD_ADVECTION (Multi-Dim advection) from thermodynamics.F to
1146        inside temp_integrate.F and salt_integrate.F and from ptracers_advection.F
1147        to inside ptracers_integrate.F ; remove ptracers_advection.F
1148    o coupling interface pkgs:
1149        [atm_compon_interf, ocn_compon_interf & atm_ocn_coupler]
1150      - change the config check to test the agreement of Ocean Depth
1151        with ATM land/sea mask (instead of ATM orography);
1152      - send to coupler the number of coupler time-steps to do for this run:
1153        this allows to check for consistency and don't need anymore to be
1154        specified in parameter file "data";
1155      in coupler:
1156      - check consistency of RunOff map versus Ocean Depth and ATM land/sea mask.
1157      - improve report to log-file of config setting (pass log-file unit to few S/R)
1158    o pkg/compon_communic:
1159      - add coupling send/receive for non-tiled integer vector;
1160      - add S/R to check and stop if any proc has an error (similar to
1161        eesupp/src/stop_if_error.F but single thread and across Comm_World).
1162    o pkg/exch2:
1163      - in exch2*_get_rx[1,2]: use new list "W2_tileIndex" to replace search
1164        through list of all tiles my proc owns.
1165    o model/src:
1166      - AUTODIFF only: in calc_adv_flow.F, recompute rTransKp (instead of copying
1167        from rTrans) to simplify dependencies (no need to store rTrans anymore in
1168        calling S/R); this affects AD results at machine truncation level:
1169        update AD-output (TAF) of experiments: 1D_ocean_ice_column,
1170        bottom_ctrl_5x5 & obcs_ctrl (12 digits for AD grad, same FWD grad).
1171    o tools/build_options:
1172      - simplify Warnings options (-ieee & -devel cases) in linux_amd64_gfortran
1173    o coupling interface pkgs:
1174        [compon_communic, atm_compon_interf & ocn_compon_interf]
1175      - move declaration of local array "ibuf" out of header file "CPLR_SIG.h"
1176        to each S/R that needs it; remove un-used variables.
1177      - change component tile registration (cpl_register.F in both compon_interf
1178        and mitcomponent_tile_register.F) to pass the full list of tiles
1179        information (including bi,bj) in 1 vector (instead of in a bi,bj matrix).
1180      - with pkg/exch2: adopt the same convention used for I/O to define mapping
1181        towards coupler global array (unless W2_useE2ioLayOut=F):
1182         a) can now use different tiling between atm & ocn comp.
1183         b) no needs to modify the run-Off map when changing tiling (was needed
1184            even if using the same tiling between atm & ocn).
1185         c) will allow to run with blank-tiles in 1 component (e.g., for ocean
1186            full land tiles); not yet tested.
1187      - check for valid mapping from comp. tile to coupler global array
1188      - improve report of tile registration results to log file.
1189    o pkg/exch2:
1190      - in eesupp/src/eeboot.F: move call to W2_EEBOOT before Coupler
1191        tile-registration (CPL_REGISTER);
1192      - activate (un-comment) definition and setting of "W2_tileIndex" list to
1193        store the local bi,bj indices of each tile;
1194      - also print bi,bj in local report to log file;
1195      - fix pkg/debug/debug_cs_corner_uv.F for the case nSy > 1 (left from
1196        Jun 2009 modif of pkg/exch2).
1197    o testing on baudelaire:
1198      - run 2 tests at a time: no significant slow down (since enough cpu) and
1199        get the full set of test done earlier
1200      - switch the ifort test to "-devel" ; run the OpenAD test everyday.
1201    o model/src/thermodynamics.F and routines called from it:
1202      - pkg/gmredi: gmredi_residual_flow.F (replacing gmredi_calc_uvflow.F &
1203        gmredi_calc_wflow.F) to update eulerian velocity (input) into residual
1204        velocity (outp) by adding bolus velocity.
1205      - model/src: calc_adv_flow.F (replacing calc_common_factors.F) to compute
1206        mass transport from velocity + lateral grid cell area
1207      - rename calc_gt.F to temp_integrate.F (includes call to TIMESTEP_TRACER)
1208      - rename calc_gs.F to salt_integrate.F (includes call to TIMESTEP_TRACER)
1209     in thermodynamics.F
1210      - remove k from thermodynamics.F and move it to temp_integrate.F
1211        salt_integrate.F and ptracers_integrate.F (now done inside the tracer
1212        loop).
1213      - compute locally (in thermodynamics.F) 3-D velocity field that is used to
1214        advect tracers; pass it as argument to GAD_ADVECTION, GAD_SOM_ADVECT,
1215        PTRACERS_ADVECTION, TEMP_INTEGRATE, SALT_INTEGRATE, PTRACERS_INTEGRATE,
1216        GAD_IMPLICIT_R and PTRACERS_IMPLICIT
1217      - update AD-output (TAF & OAD) of experiments: 1D_ocean_ice_column,
1218        global_ocean.90x40x15, tutorial_global_oce_biogeo and
1219        tutorial_tracer_adjsens (+ TLM output).
1220    o tools/OAD_support and (verification/*/) code_oad:
1221      - OAD_support/cb2mGetModules.csh: add PACKAGES_CONFIG.h in header file to
1222        module conversion ; remove unneeded CPP_EEOPTIONS.h.
1223      - code_oad/CPP_OPTIONS.h: remove PACKAGES_CONFIG.h and use a more standard
1224        version (closer to model/inc/CPP_OPTIONS.h).
1225    o model/src:
1226      - remove parameter "useOldFreezing" from PARAMS.h and push it to the
1227        retired list of parameters (routine FREEZE has been replace by surface
1228        freezing (10.yrs ago) and by pkg/frazil (interior freezing).
1229    o pkg/gmredi:
1230      - add option (GM_CALC_TRANSP_FROM_VEL) to compute transport directly from
1231        velocity (same scheme but affects machine truncation) for GM_AdvForm.
1232      - update output of FWD experiments: front_relax.bvp,
1233        global_ocean.90x40x15.dwnslp, global_ocean.cs32x15 and ideal_2D_oce.
1234    
1235    checkpoint64q (2013/11/17)
1236    o verification:
1237      - generate new output on baudelaire (gfortran, -ieee) for OpenAD experiments
1238        tutorial_global_oce_biogeo and global_ocean.90x40x15.
1239      - generate new output (growth & melt) for seaice_itd experiment after
1240        updating the input pickup_seaice files (previously wrong).
1241    o pkg/cost:
1242      - define a "final cost function" for each tile, and use GLOBAL_SUM_TILE_RL
1243        (instead of _GLOBAL_SUM_RL) to get the final cost from all procs & threads:
1244        o this fixes global-sum value if multi-threads (since GLOBAL_SUM_RL
1245          cannot be applied to var in common block).
1246        o allows to get results independent of tile-per-proc setting (if using
1247          slower GLOBAL_SUM_SEND_RECV option).
1248      - update accordingly: seaice_cost_final.F, shelfice_cost_final.F,
1249        thsice_cost_final.F and ecco_cost_final.F (this one affects lab_sea
1250        forward gradients: update output).
1251      - update */code_oad/externalDummies.F by adding dummy GLOBAL_SUM_TILE_RL
1252        S/R and, for most exp., also comment out GLOBAL_SUM_R8.
1253    o pkg/mom_common:
1254      - move to pkg/mom_common and model/src (previously in tutorial_deep_convection
1255        code) 2nd version of isotropic 3-D Smagorinsky code interface: strain and
1256        viscosity are locally declared in dynmics.F and pass as argument to CALC_GW;
1257        ensure that all field value that are used are set.
1258    o tutorial_deep_convection (smag3d):
1259      - add missing scaling in mom_calc_smag_3d.F;
1260      - set smag3D_coeff in input.smag3d such that results do not change.
1261    o pkg/dic:
1262      - change dic_cost.F to compute cost on each tile first and then apply
1263        GLOBAL_SUM_TILE_RL: this affects forward gradient of AD experiments
1264        tutorial_dic_adjoffline & tutorial_global_oce_biogeo; update output.
1265      - remove kLev argument and use GLOBAL_SUM_TILE_RL in tracer_meanarea.
1266    o eesupp/src & pkg/mdsio:
1267      - remove gather/scatter_vector.F (from eesupp) and mdsio_read/writevector.F
1268        (from pkg/mdsio) since they are no longer used for tape IO.
1269      - move simple C subroutine "setdir.c" from pkg/compon_communic to eesupp/src
1270        (+ keep a copy in pkg/atm_ocn_coupler).
1271    o verification/isomip:
1272      - split domain in 8 squared tiles (instead of just 2) for FWD, AD & OAD tests.
1273    o tools/build_options:
1274      - optfile linux_amd64_ifort11, fast (no ieee) case:
1275        to get a working restart for all experiments, add "-fp-model source"
1276        to FOPTIM (also remove "-opt-streaming-stores auto" <- this is the default).
1277    
1278    checkpoint64p (2013/10/20)
1279    o pkg/autodiff:
1280      - adread_adwrite.F: when type and length do not match ALLOW_AUTODIFF_WHTAPEIO
1281        criteria, return to simple (default) tape IO format.
1282    o pkg/mdsio (+ eesupp/src):
1283      - rewrite/simplify tape-IO S/R (new S/R MDS_READ/WRITE_TAPE replace
1284        previous MDSREAD/WRITEVECTOR) with 2 array argument from each type (R4/R8);
1285      - fix globalFile and singleCpuIO options using simpler global mapping.
1286      - new pairs of scatter/gather vector S/R (one for each type, generated from
1287        template) corresponding to simpler global mapping.
1288      - adread_write.F: switch to new S/R (but leave old calls commented) and write
1289        to globalFile when parameter globalFiles is set to True.
1290      - switch on useSingleCpuIO in AD experiments: global_ocean.90x40x15 & isomip.
1291    o pkg/autodiff:
1292      - adread_adwrite.F: add a hack for RS arrays (when RS=real*4);
1293        with ALLOW_AUTODIFF_WHTAPEIO defined, since corresponding (real*4) is
1294        missing, just add a STOP if array type do not match.
1295    o pkg/exf:
1296      - to allow to use seaice-fraction from pkg/exf in other pkgs than pkg/seaice:
1297         rename CPP option EXF_ALLOW_SEAICE_RELAX to EXF_SEAICE_FRACTION
1298         and rename array obsSIce to exf_iceFraction.
1299    o tutorial_deep_convection:
1300      - add 1rst version of isotropic 3-D Smagorinsky code (from Louis-Philippe),
1301        for now all in this exp. code dir.
1302      - add secondary test using Smag-3D viscosity (keep very low backgroud visc for
1303        testing) and flux-limter advection scheme for Temp. (no explicit diffusion).
1304    o eesupp/src:
1305      - added SINGLE_DISK_IO option because reading of parameter files on
1306        very large number of processors did not work with existing set-up
1307    
1308    checkpoint64o (2013/09/25)
1309    o pkg/atm_phys & atm_compon_interf:
1310      - allows for coupling of gray-atmosphere (atm_phys) with ocean.
1311    o tools/build_options:
1312      - switch from "-fPIC" to "-mcmodel=medium" in optfiles: linux_amd64_gfortran
1313        & linux_amd64_ifort11 and in linux_amd64_g77 & linux_amd64_open64 also
1314        remove CPP setting (was identical to genmake2 default).
1315    o pkg/gmredi & model/src: Some updating and work done on the residual model.
1316      - created new file model/src/calc_eddy_stress.F to calculate the eddy stress.
1317      - fixed up the calculation of the eddy stress and how it is added to the
1318        external forcing via taueddy_external_forcing.F
1319      - at the moment, it is very experimental and only works with the variable eddy
1320        diffusivity calculated in gmredi_k3d.F
1321    o pkg/seaice/seaice_check.F: add a check to catch the case of specifying
1322        lw/swfluxfile instead of lw/swdownfile in data.exf together with pkg/seaice
1323    o testreport (& tools/do_tst_2+2):
1324      - for MPI test, set default COMMAND to 'mpirun -v -np TR_NPROC ./{executable}'
1325    o tools/build_options: linux_amd64_gfortran & linux_amd64_ifort11:
1326      - remove CPP='cpp -traditional -P' (this is genmake2 default)
1327      - add switch (for big setups) to use 'medium' memory-model (but leave it
1328        commented out for now). Note: needed with FC 19 to compile big setups.
1329    o pkg/atm_compon_interf:
1330      - regroup per field origin (model & pkgs) the coupling storage routines
1331         (which accumalate in time each coupling field)
1332      - move bi,bj loops inside atm_store_my_data.F and store also wind-stress;
1333        update accordingly + simplify aim_do_physics.F

1336    o pkg/bbl:
1337      - update formulation to reduce dispersion of tracer properties in bbl
1338      - replaced horizontal and vertical transport parameters with velocities
1339      - changes results for verification/global_with_exf.yearly
1340    o verification/halfpipe_streamice:
1341      - change to matrix construction; update both Fwd & AD output.
1342    o verification/tutorial_tracer_adjsens:
1343      - OpenAD test: switch to vector-invariant momentum since fluxform with
1344        rStar causes problems with OpenAD; update output.
