4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/seaice/seaice_growth:
8      - fix a bug in the lateral melt parameterization for SEAICE_ITD
9        in seaice_growth; tempFrz needs to be computed inside the i/j-loop
10      - rearrange loop order for better vector code in the same code block
11      - rewrite the floeDiameter formula to have fewer divisions
12      -  (miraculously) none of this changes the results of seaice_itd
13    o pkg/rw:
14      - add RS version of S/R READ_MFLDS_LEV.
15    o pkg/streamice:
16      - fix the restart test by writing/reading pickup_streamice files.
17    o pkg/seaice:
18      - refine checks for jfnk-related parameters
19      - comment out if statement with SEAICEuseIMEX parameter as long as there
20        is no IMEX code to avoid confusion and surprises
21    
22    checkpoint64u (2014/03/07)
23    o verification/MLAdjust:
24      - rename secondary test suffix:
25         1.leith  -> A4FlxF  + switch to flux-form & add side-drag
26         0.leithD -> AhFlxF  + switch to flux-form
27         0.smag   -> AhVrDv  (use Vorticity-Div. visc form) + add side-drag
28         0.leith  -> AhStTn  (use Strain-Tension visc form) + add side-drag
29    o pkg/mom_vecinv:
30      - remove unused arguments from S/R MOM_VI_HDISSIP & MOM_HDISSIP (as it used
31        to be before mom_calc_visc.F)
32      - skip the call to MOM_CALC_TENSION & MOM_CALC_STRAIN if not needed.
33      - add 2nd copy of vort3 & strain that knows about lateral BC (free/no slip):
34        this is simpler for the adjoint and for diagnostics.
35    o model/src + pkg/momentum:
36      - add input files for  2-D additional Western and Southern cell-edge wall
37         (e.g., to add "thin-wall" where it is =1).
38      - fix sideDrag option for thin-walls with Non-Lin Free-Surf
39        using 2nd hFacZ that is computed from initial (fix domain) hFac
40      - known limitations of thin wall implementation: not yet coded for sigma
41        coords; not working with CD-scheme neither.
42    o pkg/seaice:
43      - rename recently introduced parameters from (wrong name) AB to
44        BDF (backward difference time discretisation)
45      - retire runtime parameters SEAICEuseAB2, SEAICE_abEps
46    o tools/adjoint_options:
47      - remove setting of "OPENAD=true" (now set by command line "genmake2 -oad")
48    
49    checkpoint64t (2014/02/01)
50    o pkg/thsice
51      - corrected store directive fixes thsice adjoint gradient checks
52    o genmake2 & testreport:
53      - add genmake2 option "-oad" to generate a Makefile for OpenAD built and
54        in this case, use tools/adjoint_options/adjoint_oad as default AD optfile.
55        Update testreport accordingly. No need to set "export OPENAD=true"
56        in adjoint_options/adjoint_oad anymore (will be removed later).
57    o pkg/shelfice:
58      - put T & S shelfice forcing into model surfaceForcing_T,_S (for now,
59        only if SHELFICEboundaryLayer=F); Change model/src/external_forcing.F
60        so that surface forcing applies to k=kSurf if using pkg/shelfice.
61    o pkg/ctrl, pkg/grdchk, pkg/ecco:
62      - Changes to make GENARR more modular (i.e. invisible if not used)
63    o model/src/temp_integrate.F and salt_integrate.F
64      - re-include store directives that were removed on Dec 27th.
65    o model/src/external_forcing_surf.F
66      - add storage directives for EmPmR and PmEpR to avoid recomputation of
67        seaice_model in the adjoint that is problematic when seaice_model is
68        turned off in the adjoint. The resolved issue dated back to July when
69        EXTERNAL_FORCING_SURF call was moved.
70        Update global_ocean.cs32x15/*/output_adm.seaice_dynmix.txt accordingly.
71    o pkg/exf/exf_check.F
72      - fix a small bug again (originally found by Wentao Liu, now found again)
73      - streamline error output
74    o pkg/streamice and aim_v23:
75      - replace a few "_EXCH_XY_RL (" with "_EXCH_XY_RL(", so that
76        Apple's /usr/bin/cpp knows what to do:
77        Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)
78        Target: x86_64-apple-darwin13.0.0
79    
80    checkpoint64s (2014/01/05)
81    o tools/adjoint_options:
82      - switch to fastopt.net TAF server (instead of default fastopt.de) for
83        AD optfiles adjoint_diva & adjoint_f95 (similar to adjoint_default).
84    o model/src:
85      - remove some unnecessary TAF storage directives in forward_step.F and
86        in dynamics.F (note: not always removed by TAF, e.g., double storage
87        of kappaRU,kappaRV in former version of dynamics.F).
88    o model/src & pkg/ptracers:
89      - call directly GAD_IMPLICIT_R & IMPLDIFF + DWNSLP_APPLY from temp_integrate.F
90        salt_integrate.F and ptracers_integrate.F (instead of from thermodynamics.F)
91        and remove ptracers_dwnslp_apply.F & ptracers_implicit.F
92      - call MATRIX_STORE_TENDENCY_EXP for each tracer (in ptracers_integrate.F)
93      - add fZon & fMer as output argument of S/R GAD_CALC_RHS.
94      - update TAF AD-output of experiments global_ocean.90x40x15 (13 for AD-grad).
95    o useSingleCpuInput separates single-CPU input from single-CPU output;
96        for now only implemented for in exf_interp_read.F
97    o verification/advect_xy:
98      - fix missing EXCH call in local version of ini_salt.F and update output.
99    o momentum diagnostics:
100      - fix which deltaT is used in Total-Tendency diagnostics.
101      - fix typo in diagnostics for momentum tendency from AB.
102    o pkg/seaice/seaice_lsr.F: fix an initialisation bug for the
103        SEAICE_VECTORIZE_LSR_ZEBRA option that lead to NaNs on a NEC-SX8
104    
105    checkpoint64r (2013/12/08)
106    o verification/*/results:
107      - Update reference output of experiments that were passing with just 13 digits
108         (make it easier to detect future changes in results)
109    o model/src & pkg/ptracers:
110      - move calls to GAD_ADVECTION (Multi-Dim advection) from thermodynamics.F to
111        inside temp_integrate.F and salt_integrate.F and from ptracers_advection.F
112        to inside ptracers_integrate.F ; remove ptracers_advection.F
113    o coupling interface pkgs:
114        [atm_compon_interf, ocn_compon_interf & atm_ocn_coupler]
115      - change the config check to test the agreement of Ocean Depth
116        with ATM land/sea mask (instead of ATM orography);
117      - send to coupler the number of coupler time-steps to do for this run:
118        this allows to check for consistency and don't need anymore to be
119        specified in parameter file "data";
120      in coupler:
121      - check consistency of RunOff map versus Ocean Depth and ATM land/sea mask.
122      - improve report to log-file of config setting (pass log-file unit to few S/R)
123    o pkg/compon_communic:
124      - add coupling send/receive for non-tiled integer vector;
125      - add S/R to check and stop if any proc has an error (similar to
126        eesupp/src/stop_if_error.F but single thread and across Comm_World).
127    o pkg/exch2:
128      - in exch2*_get_rx[1,2]: use new list "W2_tileIndex" to replace search
129        through list of all tiles my proc owns.
130    o model/src:
131      - AUTODIFF only: in calc_adv_flow.F, recompute rTransKp (instead of copying
132        from rTrans) to simplify dependencies (no need to store rTrans anymore in
133        calling S/R); this affects AD results at machine truncation level:
134        update AD-output (TAF) of experiments: 1D_ocean_ice_column,
135        bottom_ctrl_5x5 & obcs_ctrl (12 digits for AD grad, same FWD grad).
136    o tools/build_options:
137      - simplify Warnings options (-ieee & -devel cases) in linux_amd64_gfortran
138    o coupling interface pkgs:
139        [compon_communic, atm_compon_interf & ocn_compon_interf]
140      - move declaration of local array "ibuf" out of header file "CPLR_SIG.h"
141        to each S/R that needs it; remove un-used variables.
142      - change component tile registration (cpl_register.F in both compon_interf
143        and mitcomponent_tile_register.F) to pass the full list of tiles
144        information (including bi,bj) in 1 vector (instead of in a bi,bj matrix).
145      - with pkg/exch2: adopt the same convention used for I/O to define mapping
146        towards coupler global array (unless W2_useE2ioLayOut=F):
147         a) can now use different tiling between atm & ocn comp.
148         b) no needs to modify the run-Off map when changing tiling (was needed
149            even if using the same tiling between atm & ocn).
150         c) will allow to run with blank-tiles in 1 component (e.g., for ocean
151            full land tiles); not yet tested.
152      - check for valid mapping from comp. tile to coupler global array
153      - improve report of tile registration results to log file.
154    o pkg/exch2:
155      - in eesupp/src/eeboot.F: move call to W2_EEBOOT before Coupler
156        tile-registration (CPL_REGISTER);
157      - activate (un-comment) definition and setting of "W2_tileIndex" list to
158        store the local bi,bj indices of each tile;
159      - also print bi,bj in local report to log file;
160      - fix pkg/debug/debug_cs_corner_uv.F for the case nSy > 1 (left from
161        Jun 2009 modif of pkg/exch2).
162    o testing on baudelaire:
163      - run 2 tests at a time: no significant slow down (since enough cpu) and
164        get the full set of test done earlier
165      - switch the ifort test to "-devel" ; run the OpenAD test everyday.
166    o model/src/thermodynamics.F and routines called from it:
167      - pkg/gmredi: gmredi_residual_flow.F (replacing gmredi_calc_uvflow.F &
168        gmredi_calc_wflow.F) to update eulerian velocity (input) into residual
169        velocity (outp) by adding bolus velocity.
170      - model/src: calc_adv_flow.F (replacing calc_common_factors.F) to compute
171        mass transport from velocity + lateral grid cell area
172      - rename calc_gt.F to temp_integrate.F (includes call to TIMESTEP_TRACER)
173      - rename calc_gs.F to salt_integrate.F (includes call to TIMESTEP_TRACER)
174     in thermodynamics.F
175      - remove k from thermodynamics.F and move it to temp_integrate.F
176        salt_integrate.F and ptracers_integrate.F (now done inside the tracer
177        loop).
178      - compute locally (in thermodynamics.F) 3-D velocity field that is used to
179        advect tracers; pass it as argument to GAD_ADVECTION, GAD_SOM_ADVECT,
180        PTRACERS_ADVECTION, TEMP_INTEGRATE, SALT_INTEGRATE, PTRACERS_INTEGRATE,
181        GAD_IMPLICIT_R and PTRACERS_IMPLICIT
182      - update AD-output (TAF & OAD) of experiments: 1D_ocean_ice_column,
183        global_ocean.90x40x15, tutorial_global_oce_biogeo and
184        tutorial_tracer_adjsens (+ TLM output).
185    o tools/OAD_support and (verification/*/) code_oad:
186      - OAD_support/cb2mGetModules.csh: add PACKAGES_CONFIG.h in header file to
187        module conversion ; remove unneeded CPP_EEOPTIONS.h.
188      - code_oad/CPP_OPTIONS.h: remove PACKAGES_CONFIG.h and use a more standard
189        version (closer to model/inc/CPP_OPTIONS.h).
190    o model/src:
191      - remove parameter "useOldFreezing" from PARAMS.h and push it to the
192        retired list of parameters (routine FREEZE has been replace by surface
193        freezing (10.yrs ago) and by pkg/frazil (interior freezing).
194    o pkg/gmredi:
195      - add option (GM_CALC_TRANSP_FROM_VEL) to compute transport directly from
196        velocity (same scheme but affects machine truncation) for GM_AdvForm.
197      - update output of FWD experiments: front_relax.bvp,
198        global_ocean.90x40x15.dwnslp, global_ocean.cs32x15 and ideal_2D_oce.
199    
200    checkpoint64q (2013/11/17)
201    o verification:
202      - generate new output on baudelaire (gfortran, -ieee) for OpenAD experiments
203        tutorial_global_oce_biogeo and global_ocean.90x40x15.
204      - generate new output (growth & melt) for seaice_itd experiment after
205        updating the input pickup_seaice files (previously wrong).
206    o pkg/cost:
207      - define a "final cost function" for each tile, and use GLOBAL_SUM_TILE_RL
208        (instead of _GLOBAL_SUM_RL) to get the final cost from all procs & threads:
209        o this fixes global-sum value if multi-threads (since GLOBAL_SUM_RL
210          cannot be applied to var in common block).
211        o allows to get results independent of tile-per-proc setting (if using
212          slower GLOBAL_SUM_SEND_RECV option).
213      - update accordingly: seaice_cost_final.F, shelfice_cost_final.F,
214        thsice_cost_final.F and ecco_cost_final.F (this one affects lab_sea
215        forward gradients: update output).
216      - update */code_oad/externalDummies.F by adding dummy GLOBAL_SUM_TILE_RL
217        S/R and, for most exp., also comment out GLOBAL_SUM_R8.
218    o pkg/mom_common:
219      - move to pkg/mom_common and model/src (previously in tutorial_deep_convection
220        code) 2nd version of isotropic 3-D Smagorinsky code interface: strain and
221        viscosity are locally declared in dynmics.F and pass as argument to CALC_GW;
222        ensure that all field value that are used are set.
223    o tutorial_deep_convection (smag3d):
224      - add missing scaling in mom_calc_smag_3d.F;
225      - set smag3D_coeff in input.smag3d such that results do not change.
226    o pkg/dic:
227      - change dic_cost.F to compute cost on each tile first and then apply
228        GLOBAL_SUM_TILE_RL: this affects forward gradient of AD experiments
229        tutorial_dic_adjoffline & tutorial_global_oce_biogeo; update output.
230      - remove kLev argument and use GLOBAL_SUM_TILE_RL in tracer_meanarea.
231    o eesupp/src & pkg/mdsio:
232      - remove gather/scatter_vector.F (from eesupp) and mdsio_read/writevector.F
233        (from pkg/mdsio) since they are no longer used for tape IO.
234      - move simple C subroutine "setdir.c" from pkg/compon_communic to eesupp/src
235        (+ keep a copy in pkg/atm_ocn_coupler).
236    o verification/isomip:
237      - split domain in 8 squared tiles (instead of just 2) for FWD, AD & OAD tests.
238    o tools/build_options:
239      - optfile linux_amd64_ifort11, fast (no ieee) case:
240        to get a working restart for all experiments, add "-fp-model source"
241        to FOPTIM (also remove "-opt-streaming-stores auto" <- this is the default).
242    
243    checkpoint64p (2013/10/20)
244    o pkg/autodiff:
245      - adread_adwrite.F: when type and length do not match ALLOW_AUTODIFF_WHTAPEIO
246        criteria, return to simple (default) tape IO format.
247    o pkg/mdsio (+ eesupp/src):
248      - rewrite/simplify tape-IO S/R (new S/R MDS_READ/WRITE_TAPE replace
249        previous MDSREAD/WRITEVECTOR) with 2 array argument from each type (R4/R8);
250      - fix globalFile and singleCpuIO options using simpler global mapping.
251      - new pairs of scatter/gather vector S/R (one for each type, generated from
252        template) corresponding to simpler global mapping.
253      - adread_write.F: switch to new S/R (but leave old calls commented) and write
254        to globalFile when parameter globalFiles is set to True.
255      - switch on useSingleCpuIO in AD experiments: global_ocean.90x40x15 & isomip.
256    o pkg/autodiff:
257      - adread_adwrite.F: add a hack for RS arrays (when RS=real*4);
258        with ALLOW_AUTODIFF_WHTAPEIO defined, since corresponding (real*4) is
259        missing, just add a STOP if array type do not match.
260    o pkg/exf:
261      - to allow to use seaice-fraction from pkg/exf in other pkgs than pkg/seaice:
262         rename CPP option EXF_ALLOW_SEAICE_RELAX to EXF_SEAICE_FRACTION
263         and rename array obsSIce to exf_iceFraction.
264    o tutorial_deep_convection:
265      - add 1rst version of isotropic 3-D Smagorinsky code (from Louis-Philippe),
266        for now all in this exp. code dir.
267      - add secondary test using Smag-3D viscosity (keep very low backgroud visc for
268        testing) and flux-limter advection scheme for Temp. (no explicit diffusion).
269    o eesupp/src:
270      - added SINGLE_DISK_IO option because reading of parameter files on
271        very large number of processors did not work with existing set-up
272    
273    checkpoint64o (2013/09/25)
274    o pkg/atm_phys & atm_compon_interf:
275      - allows for coupling of gray-atmosphere (atm_phys) with ocean.
276    o tools/build_options:
277      - switch from "-fPIC" to "-mcmodel=medium" in optfiles: linux_amd64_gfortran
278        & linux_amd64_ifort11 and in linux_amd64_g77 & linux_amd64_open64 also
279        remove CPP setting (was identical to genmake2 default).
280    o pkg/gmredi & model/src: Some updating and work done on the residual model.
281      - created new file model/src/calc_eddy_stress.F to calculate the eddy stress.
282      - fixed up the calculation of the eddy stress and how it is added to the
283        external forcing via taueddy_external_forcing.F
284      - at the moment, it is very experimental and only works with the variable eddy
285        diffusivity calculated in gmredi_k3d.F
286    o pkg/seaice/seaice_check.F: add a check to catch the case of specifying
287        lw/swfluxfile instead of lw/swdownfile in data.exf together with pkg/seaice
288    o testreport (& tools/do_tst_2+2):
289      - for MPI test, set default COMMAND to 'mpirun -v -np TR_NPROC ./{executable}'
290    o tools/build_options: linux_amd64_gfortran & linux_amd64_ifort11:
291      - remove CPP='cpp -traditional -P' (this is genmake2 default)
292      - add switch (for big setups) to use 'medium' memory-model (but leave it
293        commented out for now). Note: needed with FC 19 to compile big setups.
294    o pkg/atm_compon_interf:
295      - regroup per field origin (model & pkgs) the coupling storage routines
296         (which accumalate in time each coupling field)
297      - move bi,bj loops inside atm_store_my_data.F and store also wind-stress;
298        update accordingly + simplify aim_do_physics.F
299    
300    checkpoint64n (2013/08/26)
301    o pkg/bbl:
302      - update formulation to reduce dispersion of tracer properties in bbl
303      - replaced horizontal and vertical transport parameters with velocities
304      - changes results for verification/global_with_exf.yearly
305    o verification/halfpipe_streamice:
306      - change to matrix construction; update both Fwd & AD output.
307    o verification/tutorial_tracer_adjsens:
308      - OpenAD test: switch to vector-invariant momentum since fluxform with
309        rStar causes problems with OpenAD; update output.
310    o tools:
311      - genmake2: define a common prefix for all temp-file names ; move them
312        to local /tmp disk (but would be easy to move them back);
313      - xmakedepend: apply the same switch for temp-files.
314    o pkg/offline:
315      - changes for use with rStar (NLFS): assume that we continue to provide
316        UVELMASS/hFacW_ini & VVELMASS/hFacS_ini (hFacWi,S_ini as written in grid
317        output files) and apply r* scaling at each time-step (function of the time
318        varying Eta field); use normal pickup files (needed for restart with NLFS).
319    o adjoint with OpenAD:
320      - move OpenAD-specific files from verification/OpenAD/code_oad_all to a new
321        package openad.  This package has to be compiled for all runs with OpenAD
322        instead of specifying code_oad_all as a modification directory.
323      - link the fortran templates from tools/OAD_support to the build directory
324        for preprocessing to avoid conflicts between different setups compiled
325        simultaneously and simplify cleanup.
326    o pkg/exf:
327      - in exf_getforcing.F: comment out most of the EXCH calls (fields used by
328        main model or other pkgs are exchanged in EXF_MAPFIELDS).
329    o model/src:
330      - do_stagger_fields_exchanges.F: skip EXCH calls when using pkg/offline
331        (similar to do_fields_blocking_exchanges.F).
332    o tools/genmake2:
333      - remove TAF output src code just before calling staf (when not doing a fresh
334        built, will stop if things go wrong with staf).
335      - fix target "adobj" (left from TAF version-2 transition)
336    o pkg/diagnostics:
337      - add a parameter to track the status of pkg/diagnostics activation;
338        this replace/extend the use of logical param "settingDiags" (to check
339        when adding diag to the list) to also check any DIAGNOSTICS_[]FILL* call.
340        New S/R to print error message and stop when pkgStatus is not right.
341      - to try: add a warning when "data.diagnostics" exist but useDiagnostics=F.
342    
343    checkpoint64m (2013/08/13)
344    o model/inc:
345      - move FCORI_MACROS.h from PARAMS(_MACROS).h to GRID_MACROS.h (left from
346        8 yrs ago modif when Coriolis arrays were moved from PARAMS.h to GRID.h)
347    o pkg/kpp & aim_v23:
348      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
349    o pkg/seaice:
350      - restore (last time on 2011/12/24) ability to compile pkg/seaice with
351        undefined pkg/exf ALLOW_ATM_TEMP or ALLOW_RUNOFF CPP-options.
352      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
353    o eesupp/src:
354      - fix check for overlap-size argument (myOLn.GT.MAX_OLY_EXCH)
355        in exch1_rx[_ad].template (thanks to Francois Lefeuvre report).
356    o switch to TAF version-2:
357      - add flow directives to "freeze" naming convention for ad-routines that
358        are used in I/O routines of adjoint state and associated common blocks
359        that are used in adcommon.h (backward compatible with version-1)
360      - update all ad-optfiles (in tools/adjoint_options + few local to some
361        verification exp) to switch to latest TAF version (currently 2.5.5);
362        merge "*_mpi" adoptfiles into the corresponding non-mpi (but commented
363        out except for diva).
364      - the major change with TAF version-2 is that both the differentiated
365        routines and the forward routines (new) are returned as part of the TAF
366        output source code. Update genmake2 accordingly.
367      - new output for AD experiment tutorial_global_oce_biogeo (better AD gradient
368        with version-2 when compared to TLM or FWD gradient); other experiments
369        output show minor changes (machine truncation level); update the few AD &
370        TLM output with 12 matching digits only (some prior to version-2 switch).
371    
372    checkpoint64l (2013/08/05)
373    o model/src:
374      - in dynamics.F, skip the call to CALC_VISCOSITY if momViscosity=F
375      - main_do_loop.F: no longer includes additional (AUTODIFF) header files
376        when using TAF but only if using OpenAD.
377    o pkg/mom_common+fluxform+vecinv:
378      - always set horiz. viscosity arrays to background value before calling
379        MOM_CALC_VISC (in MOM_FLUXFORM & MOM_VECINV) and call S/R MOM_CALC_VISC
380        only when using variable horiz. viscosity (useVariableVisc=T);
381      - simplify mom_vecinv.F (only 1 block for momViscosity).
382    o pkg/mom_common: variable horiz. viscosity in NH code
383      - move horiz-viscosity 3-D arrays viscAh_W & viscA4_W (used in calc_gw.F)
384        from model/inc/NH_VARS.h to pkg/mom_common/MOM_VISC.h
385      - store in common block (in MOM_VISC.h) logical parameters: useHarmonicVisc,
386        useBiharmonicVisc & useVariableVisc.
387      - fix old bug (already in 1rst implementation of variable horizontal viscosity
388        in calc_gw.F, version 1.27, 2006/06/20):
389        horizontal bi-harmonic viscosity in gW was missing when wiscA4W=0
390        even if variable bi-harmonic viscosity (e.g., viscA4Grid) was non-zero.
391      - change background horiz viscosity in vertical momentum (gW) to always be
392        viscAhW,viscA4W (instead of switching to viscAhD, viscA4D when using
393        any type of variable viscosity, e.g., viscAh/4Grid)
394      - change default value of viscAhW,viscA4W to viscAhD,viscA4D (instead of
395        viscAh,viscA4) which default to viscAh,viscA4 :  this avoid missing
396        horiz. viscosity in W eq when just setting viscAhD/Z,viscA4D/Z (since
397        default viscAh,viscA4 is zero).
398    o model/src:
399      - extend length of drC & recip_drC from Nr to Nr+1.
400    o Divided Adjoint (DIVA) with MPI:
401      - genmake2: do not create local ./mpi_headers dir when no file to copy into.
402      - remove option ALLOW_DIVIDED_ADJOINT_MPI (replaced by ALLOW_DIVIDED_ADJOINT
403        and ALLOW_USE_MPI) from model/src code and from ECCO_CPPOPTIONS.h.
404    
405    checkpoint64k (2013/07/23)
406    o tools/OAD_support:
407      - avoid the need for file "oadtempflile" in insertTemplateDir.bash
408        and remove it from genmake2.
409    o tools/build_options:
410      - remove MPI_HEADER_FILES_INC setting (no longer used) and comment out
411        MPI_HEADER_FILES list (let genmake2 find the missing headers)
412    o verification/halfpipe_streamice:
413      - change to driving stress formulation; update both Fwd & AD output.
414    o tools/genmake2 and Divided Adjoint with MPI:
415      - remove default setting of MPIINCLUDEDIR from $MPIHOME (always been broken);
416      - only create local ./mpi_headers dir if using MPI and MPIINCLUDEDIR is set;
417      - add new variable (LOCAL_MPI_HEADERS, replace MPI_HEADER_FILES_INC) in
418        Makefile, which is set by genmake2, and check which mpi-headers are needed.
419        Note: need to update adjoint_options/adjoint_diva_mpi accordingly.
420      - update target "CLEAN" (to also remove ./mpi_headers/ dir).
421    o testreport:
422      - changes for Divided Adjoint Run: when file "run_ADM_DIVA" is present,
423        perform additional runs (number of additional runs is "add_DIVA_runs" taken
424        from file run_ADM_DIVA ; should match "nchklev_3" in file "code_ad/tamc.h").
425    o verification/lab_sea (AD test):
426      - change to test Divided Adjoint Run in this set-up (both standard AD test
427        and 2 secondary AD test: noseaice + noseaicedyn); drop the evp AD test.
428    o pkg atm_ & ocn_compon_interf:
429      - remove cpl_earlyExpImpCall=F option (was mainly a hack added for the old
430        staggerTimeStep implementation) and disable (retired) corresponding
431        parameter.
432    o pkg/offline:
433      - comment out unused field-array: ICEM, ConvectCount, hflx[01], icem[01];
434      - add S/R OFFLINE_CHECK to print offline parameter summary
435        and stop if loading a file that is not used;
436      - enable to calculate GMRedi tensor, KPP mixing and convective index
437        when the corresponding file(s) is/are not specified (but pkg is used).
438      - comment out resetting of monitorFreq (to endTime) since it still useful
439        for monitoring CFL numbers and checking offline fields.
440    o OpenAD:
441      - do not define OAD_DEBUG (in tools/adjoint_options/adjoint_oad) to get
442        smaller standard output) and generate new (smaller) output (on baudelaire
443        using gfortran with -ieee) for exp. tutorial_tracer_adjsens
444    o model/src:
445      - call EXTERNAL_FORCING_SURF outside bi,bj loops (in do_oceanic_phys.F),
446        (where external_forcing_adjust was called) and change list of arguments;
447      - merge external_forcing_adjust.F into external_forcing_surf.F
448      - put surface relaxation of SST & SSS in new S/R (forcing_surf_relax.F)
449        which also contains balancing surface relaxation (ALLOW_BALANCE_RELAX,
450        previously in file "balance_relax.F", now removed); remove corresponding
451        arrays in FFIELDS.h.
452      - EXTERNAL_FORCING_SURF is now called when using pkg/offline; implement
453        a hack for getting back surfaceForcingS (loaded from file) when using
454        ALLOW_OLD_VIRTUALFLUX (pkg/dic, in DIC_OPTIONS.h) in offline set-up.
455      - update output of AD test experiment global_ocean.cs32x15.seaice_dynmix
456        (was getting only 11 digits for AD-grad, due to different truncation
457         error in AD code).
458    
459    checkpoint64j (2013/07/04)
460    o pkg/offline:
461      - to enable the use of other features with pkg offline (e.g., obcs),
462        also call S/R DO_OCEANIC_PHYS in offline run - more modifs to come.
463      - comment out "allowFreezing" (now active) in 2 offline testing exp.
464    o pkg/exf ALLOW_RUNOFTEMP
465      - fix sign and make compatible with temp_EvPrRn .NE. UNSET_RL
466      - ahdded RUNOFTEMP test to verification/global_ocean.cs32x15/input.seaice
467      - changes verification/global_ocean.cs32x15/results/output.seaice.txt
468    o pkg/atm_phys:
469      - allows to add some damping on uVel,vVel (strength only function of k).
470    o verification, ad-tests:
471      - reduce length of the simulation for AD test: global_ocean.cs32x15.seaice,
472        global_ocean_ebm and offline_exf_seaice.thsice.
473    o verification/halfpipe_streamice:
474      - found a bug in s/r pkg/streamice/streamice_advect_thickness which caused
475        flux input boundary conditions to be ignored; a fix for this bug changed
476        verification results for forward test.
477      - add adjoint test.
478    o pkg/ptracers:
479      - allow to restart without SOM pickup (resetting SOM to zero).
480    o pkg/gmredi:
481      - New parameterisation for the calculation of K and (GM_PsiX,GM_PsiY) added.
482      - It uses mixing length theory and suppression by steering level effects to
483        calculate a diffusivity used in the Redi tensor (see Bates et al., submitted
484        to JPO, for more details).
485      - It also uses the diffusivity to calculate an eddy induced streamfunction
486        based on a PV closure (rather than a buoyancy closure as in GM).
487      - New files added to pkg/gmredi:
488        gmredi_k3d.F calculates the diffusivity for the Redi tensor and the eddy
489          induced overturning streamfunction (called from gmredi_calc_tensor)
490        gmredi_calc_eigs.F calculates the eigenvalues and eigenvectors required
491          for use in gmredi_k3d
492        gmredi_calc_urms.F calculates the the rms eddy velocity used to calculate
493          the eddy diffusivity
494    
495    checkpoint64i (2013/06/18)
496    o pkg/cheapaml:
497      - take src files from MITgcm_contrib/verification_other/offline_cheapaml/code
498        that enable the use of seaice (pkg/thsice thermo & pkg/seaice dynamics)
499        with pkg/cheapaml.
500    o utils/python: add subpackage for cubed sphere function, first example is
501        simple cs.pcol to plot 2D fields on a map
502    o pkg/streamice:
503      - This is a new package in MITgcm, which solves dynamic equations for ice
504         sheets and ice streams
505      - At the moment it is independent of atmosphere/ocean dynamics, or any
506        other physical packages in MITgcm, even ShelfIce (although it is anticipat-
507        ed that this will change)
508      - There is a new verification exercise that tests it, halfpipe_streamice,
509        evolves a 40x80 km ice stream/ice shelf (at coarse resolution) in a
510        rectangular embayment
511      - halfpipe_streamice is forward-only for now, will have TAF test soon
512      - for questions, email dgoldber@mit.edu
513    o pkg/thsice:
514      - fix filling of snow-precip diagnostic (SIsnwPrc) (left from the removing
515        of snowPrc from common bloc, on May 2nd, thsice_step_fwd.F revision 1.40);
516      - remove diagnostics 'SI_FrcFx' ( now identical to 'SI_Fract' with new
517         call sequence: ice-Thermo(thsice),ice-Dyn,ice-Advect );
518      - allow precip from pkg/cheapaml to make snow over seaice.
519    o pkg/cfc:
520      - move in separated header file (CFC_ATMOS.h) time-serie arrays of Atmos CFC
521      - remove atmos CFC 2-D arrays from common bloc (now local variables)
522      - change some hard-coded constant to run time parameter for reading and
523        and interpolating atmospheric CFC ; keep same default as previously.
524      - more flexible reading of Atmos CFC (number of records no longer hard-coded)
525      - put arguments in standard order: myTime, myIter, myThid
526      - use standard S/R GET_PERIODIC_INTERVAL for time interpolation of
527        atmospheric CFC ; fix for the case myIter < PTRACERS_iter0.
528      - fix calculation of surf tendencys for partial-cell and/or Non-Lin Free-Surf
529      - new routine to print summary of CFC params and check for consistency.
530    o pkg/seaice: add uice/vice to the parameter list of s/r seaice_advdiff,
531      similar to thsice_advdiff.
532      Note that for the B-grid case the routine parameters uc/vc are overwritten.
533    o pkg/cfc:
534      - change time interpolation for atmospheric CFC-11 (now same as for CFC-12);
535        update output (CFC-11) of experiment cfc_example and tutorial_cfc_offline.
536      - fix interpolation of atmphspheric CFC between Sorthern and Northern
537        hemisphere value.
538    o pkg/seaice:
539      - allow to use seaice dynamics without pkg/exf (e.g., using pkg/cheapaml)
540    o pkg/seaice: add Adams-Bashforth2 time discretization for ice dynamics;
541                  so far only for JFNK-solver, turn on with SEAICEuseAB2 = .TRUE.
542      - requires an additional time level that is stored in the pickup
543      - you can start with AB2 from a pickup without this time level with
544        pickupStrictlyMatch = .false.
545    
546    checkpoint64h (2013/05/26)
547    o pkg/cheapaml:
548      - replace one ()**.5 with SQRT + use temp var "cdu = tau/Du" (coare3_flux);
549        affect machine truncation (but exp cheapAML_box still pass with 13 digits).
550      - consistent treatment of uWind,vWind location: assume everywhere in
551        pkg/cheapaml that they are on C-grid (@ uVel,vVel location)
552        (Note: was already the case for Tair,Qair advection);
553        add option (INCONSISTENT_WIND_LOCATION) to recover old results.
554      - compute diabatic forcing only in the interior (excluding overlap regions)
555      - fill in array "Qsw" (for short-wave heating);
556      - add diagnostic for precip ; fill-in diagnostics for cheapAML state vars
557        before any update (consistent with MITgcm state var diagnostics);
558      - cheapaml_fields_load.F & cheapaml_init_varia.F : only fill outer edges if
559        non periodic ; + adjusted for uWind,vWind (C-grid).
560    o pkg/seaice:
561      - remove dependence of pkg/seaice versus pkg/exf (file: pkg/pkg_depend) and
562        add explicitly pkg/exf in experiments that currently use pkg/seaice.
563      - allows to compile pkg/seaice without pkg/exf.
564    o tools/OAD_support:
565      - use a local copy (ourRWCPinBd) to ensure index ourRWCP stays within bounds
566        of array "ourStepOf" in function rvNextAction (revolve.F90).
567    o pkg/aim_compon_interf renamed to pkg/atm_compon_interf
568      - change pkg name (to be used with other atmospheric physics pkg)
569        but by-pass CVS when making the new pkg so that we keep the CVS history.
570    o pkg/offline:
571      - call OFFLINE_FIELDS_LOAD from pkg/offline/offline_init_varia.F
572        (previously called from pkg/dic_surfforcing_init.F)
573    o model/src:
574      - re-order sequence of calls within packages_init_variables.F, using
575        standard order, except for:
576         DIAGNOSTICS_INIT_VARIA and OFFLINE_INIT_VARIA (called @ the top),
577         CTRL_MAP_INI and OBCS_INIT_VARIABLES (called @ the bottom)
578    o new pkg: atm_phys
579      - add entry point and source code (previously in contrib
580          verification_other/atm_gray/code_gray/) for new pkg "atm_phys"
581        (atmospheric physics pkg from P. O'Gorman and T. Schneider, JCl, 2008).
582      - re-order sequence of calls within packages_readparms.F,
583         packages_init_fixed.F and packages_write_pickup.F
584        (but skip packages_init_variables.F because of TAF issues).
585      - update contrib/*/atm_gray/ experiment.
586    o pkg/seaice (ITD code):
587      - simplify and fix the writing of pickup-files for ITD case
588    o pkg/seaice (ITD code):
589      - introduce floe size dependent lateral melt for ITD case;
590      - cleaning (avoid division by zero, change to f77 syntax, remove tabs)
591      - update seaice_itd experiment main output.
592    o pkg/thsice:
593      - remove snowPrc from common block THSICE_FLUX, in THSICE_VARS.h and
594        declared it locally (without bi,bj) in thsice_main.F & aim_do_physics.F;
595        changed accordingly pkg/atm2d.
596    
597    checkpoint64g (2013/05/01)
598    o pkg/exf ALLOW_RUNOFTEMP
599      - if defined,  river and glacier runoff temperature can be read-in from
600        runoftempfile; runoftempfile needs to have same format as runofffile
601    o pkg/thsice (& pkg/bulk_force):
602      - In case Energy-Reference-Level (ERL) is used (temp_EvPrRn=0), account
603        for energy content of Precip + RunOff & Evap (like with pkg/exf).
604      - change computation domain to always be the interior (without overlap).
605      - fix bug (wrong overlap) when using EXF and stressReduction > 0.
606    o verification/tutorial_global_oce_biogeo:
607      - add preliminary OpenAD setup (still has problems)
608    o pkg/seaice:
609      - turn some parameters for choosing the convergence criterion of
610        the inexact Newton method (JFNK) into runtime parameters for convenience
611      - clean up seaice_calc_viscosities.F: remove/retire two options for
612        SEAICetaZmethod (1,2), introduce area weighting for method 3; this changes
613        the results of lab_sea/input because a division has been replaced by
614        a multiplication with the reciprocal (sumNorm)
615      - modify offline_exf_seaice/input.dyn_jfnk/data.seaice to improve
616        convergence of solver (changes results, of course), and to test some
617        new features
618    o model/src:
619      - remove unused (since Aug 2006) S/R SET_WRITE_GLOBAL_PICKUP and its call.
620      - remove unused forcing field "dQdT" and associated parameter "dQdTFile".
621      - move forcing adjustment (balancing surface forcing) in specific S/R
622        where might also be applied exchanges (if needed) to forcing arrays.
623    o pkg/shelfice:
624      - allow to specify the Ice-Shelf mass per unit area (instead of
625        shelficeLoadAnomaly) and do the conversion from one to the other
626      - move loading from file of shelficeLoadAnomaly from SHELFICE_INIT_VARIA
627        to SHELFICE_INIT_FIXED: (a) avoid some TAF recompution issues and
628        (b) will be loaded in time (before calling INI_PRESSURE) in case it is
629        needed in phi0surf for initial pressure calculation when useDynP_inEos_Zc
630      - update isomip experiment forward output (get machine truncation error
631        from conversion shelficeLoadAnomaly -> shelficeMass -> shelficeLoadAnomaly)
632    o verification/offline_exf_seaice:
633      revise data.seaice in input.thermo and input_ad and update results accordingly
634        HO = 0.2, SEAICE_areaLossFormula = 2,
635        SEAICE_growMeltByConv = .TRUE.,
636        SEAICE_doOpenWaterMelt = .TRUE.,
637      Improve consistency with input.thsice and fix the spurious 500m ice corners
638    o verification/global_ocean.cs32x15:
639      - set Energy Reference Level to liq. water @ 0 degC: temp_EvPrRn=0.,
640        in icedyn (thsice+seaice-dyn) test and update output.
641    o verification/offline_exf_seaice:
642      - adjust list of tested variables (with testreport) and update
643        standard test output with better slection of monitored fields.
644    o pkg/cd_code:
645      - swtich off Adams-Bashforth on the 1rst iteration. Update output of
646        experiment lab_sea.hb87
647    o tools/genmake2:
648      - change default makedepend from the system default to tools/xmakedepend:
649        When no makedepend is specified, select tools/xmakedepend it the test pass,
650        otherwise select the system default (if exist and pass the test) or
651        try to build cyrus-makedepend ; stop if none of the 3 works.
652    o pkg/exf & pkg/thsice:
653      - In case Energy-Reference-Level (ERL) is used (temp_EvPrRn=0), account
654        for energy content of Precip + RunOff & Evap. Assumes:
655       1) Rain has same temp as Air.
656       2) Snow has no heat capacity (consistent with seaice & thsice pkgs)
657       3) Run-Off comes at the temp of surface water (with same Cp)
658       4) Evap over ocean is released to the Atmos @ surf-temp (=SST); should be
659        put directly into Latent Heat flux & should use water-vapor heat capacity.
660       5) Evap over snow/seaice (pkg/thsice) assumes constant Lf+Lv (consistent
661        with snow having no Cp) => water vapor is released to Atmos @ 0^oC (=ERL).
662    o pkg/seaice: simplify the use of CPP flags in JFNK-related files
663        (compile when SEAICE_ALLOW_JFNK is defined)
664    o pkg/thsice:
665      - fix oceanic flux diagnostics & timeave (left from new sequence of calls
666        implementation): move THSICE_AVE call after the advection (called directly
667        from thsice_do_advect.F).
668    o verification/global_ocean.90x40x15 and OpenAD:
669      New experiment for OpenAD is identical to the one in input_ad except that
670        multiDimAdvection=.FALSE.,
671      There is still an issue with this.
672    o pkg/thsice:
673      - account for ice velocity (ocean relative velocity) in turbulent heat flux
674        at the base of the ice; update output of global_ocean.cs32x15 (icedyn)
675        and offline_exf_seaice (main test).
676    
677    checkpoint64f (2013/03/31)
678    o verification/OpenAD:
679      - new (smaller, without OAD_DEBUG) output_oadm.txt generated using gfortran.
680    o verification/isomip, pkg/shelfice and OpenAD:
681      - add OpenAD setup to this exp and make shelfice package work with OpenAD
682    o verification/tutorial_global_oce_biogeo:
683      - update AD and TLM output after turning off ALLOW_FE (in DIC_OPTIONS.h)
684    o verification/offline_exf_seaice:
685      - replace adjoint experiment (now similar to fwd input.thermo/ setup).
686    o verification/tutorial_tracer_adjsens, pkg/ptracers and OpenAD:
687      - add OpenAD setup to this exp and make ptracers package work with OpenAD
688    o pkg/seaice/seaice_evp.F:
689       mask the asymmetric contribution of the ice-ocean stress (when
690       the turningAngle is non-zero) over open water to avoid stripes
691       in the EVP-solutions after many EVP-substeps. This does not change
692       the verification experiment (because turningAngle=0 in that experiment),
693       but will affect other EVP solutions with turningAngle.ne.0
694    o verification, AD & TLM output:
695      - new TAF version 2.3.10 (previously 2.3.8) add more parenthesis in multiple
696        additions and multiplications which affect results at machine truncation
697        level. Update few AD output (1D_ocean_ice_column, bottom_ctrl_5x5,
698        lab_sea.noseaicedyn & offline_exf_seaice) and TLM output
699        (1D_ocean_ice_column & tutorial_tracer_adjsens.som81) which had only 12
700        digits of matching.
701    o pkg/seaice:
702       modify lsr-algorithm so that it vectorizes AND converges by using a
703       "zebra" method: split vector loop into two with step size 2; this
704       solves a general convergence problem for the JFNK solver on a vector
705       computer. It has the potential to even improve convergence for
706       non-vector machines, but it does change the results so it is turned
707       off by default. To turn on define CPP-flags SEAICE_VECTORIZE_LSR and
708       SEAICE_VECTORIZE_LSR_ZEBRA in SEAICE_OPTIONS.h
709    
710    checkpoint64e (2013/03/05)
711    o pkg/ecco and several verification experiments:
712       Remove special versions of the_model_main.F, the_main_loop.F, forward_step.F
713       from ecco package, and revert to unified routine in model/src/
714       Adjust verification experiments accordingly, especially gloal_oce_llc90
715       Should conclude long-standing work by Gael to reconsile the_main_loop with
716       ECCO and will enable OpenAD's revolve loop in ECCO setup.
717    o pkg/generic_advdiff:
718      - implement compressible flow method for multi-dim advection (similar to
719        gad_som_advect.F); add new option "GAD_MULTIDIM_COMPRESSIBLE" (since
720        TAF generates many recomputations) to use it; no yet coded with implicit
721        vertical advection.
722      - change experiment advect_cs (new output) and advect_xy (same output)
723        to test compressible flow multi-dim advection.
724    o pkg/generic_advdiff:
725      - fix SOM advection for unusual cases (linear Free-Surf in r*, other
726        cases where linear Free-Surf is not @ k=1, e.g., useShelfIce)
727    o pkg/seaice:
728      - fix bug in the no-slip implementation in seaice_calc_strainrates.F, this
729        bug affects two verification experiments (lab_sea and lab_sea.hb87),
730        recover old (wrong) results by setting noSlipFac = 2. in
731        seaice_calc_strainrates.F;
732      - add another averaging method for etaZ (etaZmethod=3), a mix of 2 and 0
733      - add runtime parameter SEAICE_JFNKepsilon for that finite difference
734        gradient in the Jacobian times vector operation (s/r seaice_jacvec)
735      - fix line search in seaice_jfnk.F (s/r seaice_jfnk_update)
736    o pkg/seaice: reorganize seaice_lsr.F to be able to reuse more code:
737      - new subroutines seaice_lsr_tridiagu/v
738      - introduce loop bounds i/jmin/max to be able to use a restricted
739        additive Schwarz method, but not used for now.
740      - rename SEAICE_CALC_LSR_COEFFS into SEAICE_LSR_CALC_COEFFS
741      - use new subroutines seaice_lsr_tridiagu/v in s/r seaice_preconditioner
742    o OpenAD support
743       Reorganize S/R call for overall time-stepping loop to facilitate
744       OpenAD revolve loop replacement
745       (new S/R main_do_loop.F)
746    o model/src:
747      - add 3-D array 3rd dimension to argument list of S/R ADAMS_BASHFORTH2/3;
748      - pkg/cheapaml: remove local S/R ADAMS2d and use instead standard S/R
749        ADAMS_BASHFORTH2.
750    o pkg/cheapaml:
751      - add new parameter (default=F, same as before) to disable full domain
752        (including land) periodicity in X & Y dir.
753      - new S/R CHEAPAML_COPY_EDGES to copy relaxation field into edges of
754        prognostics field ; merge the 2 S/R cycle_2d_tracer and timestep_2d_tracer
755        into single S/R CHEAPAML_TIMESTEP.
756    
757    checkpoint64d (2013/02/17)
758    o pkg/monitor (angular momentum):
759      - do not add Eta contribution to the total AM if using rigid-lid;
760      - correct for Adams-Bashforth in zonal-wind part (instead of in AM_eta).
761      - horizontal discretisation: compute Zonal wind contribution separately for
762        each component (instead of from cell centered averaged) and use the 4
763        grid-cell corner averaged value of Omega*(R*cos_Phi)^2 in AM_eta part.
764      - Check that AM is conserved with linear dynamics (momAdvection=F and linear
765        FreeSurf) if using vectorInvariant momentum.
766    o model/src (horizontal grid):
767      - move initialisation of all horizontal grid arrays to null value
768        from specific horizontal grid S/R to main S/R INI_GRID;
769      - add 2 new arrays to project model C-grid velocity on to zonal direction
770        (similar to AngleCosC & -AngleSinC but at U and V point location) and
771        compute them in S/R CALC_GRID_ANGLES.
772    o pkg/seaice: replace a hard coded parameter by a runtime parameter
773        SEAICE_JFNK_tolIter
774    o pkg/seaice: introduce a restricted additive Schwarz (RAS) method in
775        preconditioner for JFNK (run LSR into the overlaps as far as possible,
776        i.e OLx/y-2, but overwrite the solution in the overlaps)
777      - extend loop range in seaice_calc_viscosity
778      - add new parameters SEAICE_OLx/y (default = OLx/y-2)
779      - add flexible loop ranges to seaice_preconditioner, seaice_calc_lsr_coeffs
780      - slightly modify loops in tridiagonal solver lsr-preconditioner
781      - by default remove the extra exchange in seaice_preconditioner with a
782        replacement of an undocumented CPP flag by SEAICE_PRECOND_EXTRA_EXCHANGE
783      - modify offline_exf_seaice so that old results without RAS are reproduced
784        for output.dyn_jfnk.txt
785      in seaice_fgmres.F (unrelated to RAS)
786      - add a cpp-flag option for a re-ordered mapping (potentially more
787        efficient), but because this changes the results, turn it off by
788        default
789      - replace the save statement by local common blocks
790    o utils/matlab:
791      - fix tile-offset in rdmnc.m when output was produced using EXCH2.
792      - update cs_grid/bk_line scripts to use load_grid.m (in utils/matlab)
793        instead of local script "load_cs.m".
794    o pkg/seaice:
795      - fix a serious bug in seaice_fgmres.F, s/r seaice_scalprod, connected
796        to the scalarProductMetric and the unrolling. By chance this does not
797        change the verification experiment, because of the particular domain
798        decomposition
799    o pkg/diagnostics:
800      - change default missing_value from UNSET_RL to -999.
801    o pkg/layers: improve vectorization of layers_fluxcalc.F
802      - step 1: split loops, make TatU/V 2D arrays. This alone reduces the cpu
803        time spent in this routine by more than a factor of 3 on an NEC-SX8
804      - step 2: replace search algorithm by a bisection algorithm found in
805        Press et al. Numerical Recipes in Fortran. This algorithm can be
806        vectorized and finds the correct bin in approx. log2(Nlayers) steps.
807        For now, use this algorithm only for TARGET_NEC_SX defined.
808      - moved the search algorithm into a separate subroutine, that is kept
809        within the same file for automatic inlining.
810      - modified catching potential errors
811    o pkg/ecco:
812      - add compile switches ALLOW_SHALLOW_ALTIMETRY and ALLOW_HIGHLAT_ALTIMETRY.
813    o model/src, pkg/autodiff, pkg/ctrl, pkg/grdchk :
814      - modifications for ALLOW_GENTIM2D_CONTROL
815      -- forward_step.F, the_main_loop.F : pass options and arrays for adjoint tapes.
816      -- load_fields_driver.F : add call to CTRL_MAP_GENTIM2D( myTime, myIter, myThid )
817      -- add xx_gentim2d0/1 in ctrl_ad_check_lev1_dir.h checkpoint_lev1_directives.h etc
818      -- use ctrl_swapffields.F (new) instead of exf_SwapFFields.F in ctrl_get_gen.F
819    o model/src:
820      - account for moist thermodynamics in (dry) potential temperature equation;
821        update results of experiments: aim.5l_cs (x2), fizhi-cs (std + aqualev)
822        and cpl_aim+ocn.
823      - also switch to standard compiler (gfortran, was using ifort previously)
824        for fizhi-cs experiments reference output.
825    o pkg/ctrl:
826      - 1st step toward generic time-varying control variable (2D) via CPP option
827        ALLOW_GENTIM2D_CONTROL
828      - note new namelist ctrl_nml_genarr in data.ctrl
829    o verification/global_ocean.cs32x15:
830      - switch off OLD_THSICE_CALL_SEQUENCE (both forward and AD code) to use new
831        thsice calling sequence and update "output.icedyn.txt" output file.
832    o pkg/ptracers:
833      - from Ryan A.: code to allow to restart a tracer at regular time interval
834        specifying a reset frequency and a reset-phase (for each tracers).
835    o pkg/thsice:
836      - implement new sequence of calls for thsice+seaice:
837          previously:   ice-Dyn,ice-Advect,ice-Thermo(thsice)
838          new sequence: ice-Thermo(thsice),ice-Dyn,ice-Advect
839      - allows (with temporary CPP option "#define OLD_THSICE_CALL_SEQUENCE"
840        in CPP_OPTIONS.h) to recover old sequence;
841      - update diagnostics for Intermediate State thsice diagnostics: now filled
842        just before advection (instead of just after advection in old sequence);
843      - update output of experiment offline_exf_seaice (standard test);
844      - in global_ocean.cs32x15 exp., postpone output.icedyn.txt update
845        by setting #define OLD_THSICE_CALL_SEQUENCE in CPP_OPTIONS.h
846    o pkg/aim_v23:
847      - use tiled array for aim_CO2 and surface wind speed for export to coupler;
848      - use standard pkg/mdsio routines to read & write CO2 pickup file;
849      - in-line S/R AIM_AIM2DYN_EXCHANGES in aim_do_physics.F;
850      - Implement new sequence of calls for seaice advection (with thsice and
851        seaice diffusion): do ice advection after ice-Thermodynamic (previously
852        was done before); change aim_do_physics.F (split the bi,bj loops block);
853      - use same CPP option (OLD_THSICE_CALL_SEQUENCE) to recover old sequence;
854    o pkg/thsice:
855      - add a missing EXCH of sIceLoad in thsice_main.F (ocean set-up) for the case
856        where just seaice diffusion is used without seaice-dynamics.
857    
858    checkpoint64c (2013/01/18)
859    o pkg/seaice:
860      - add a parameter JFNKres_tFac that can replace JFNKres_t
861        (= JFNKres_tFac*JFNKresidual before JFNK solver)
862      - add a line search option to the JFNK solver
863      - move update of u/vIce and computation of initial residual into a separate
864        routine (same file); makes the code a little easier to read (?)
865      - the line search requires computation of the residual and for some reason
866        I cannot do the update of u/vIce at the beginning of the Newton loop
867        without changing the results, so we move computation of the new residual
868        also to the end of the Newton loop, even without the line search
869    o pkg/mdsio:
870      - write missing value (corresponding to undefined array value) to meta files;
871        skip this if missing value is one (UNSET_RL would be a better value for the
872        case of undefined missing value but it's current the default missing-value);
873        Also update mdsio_read_meta.F (reading timeInterval & missing-value).
874    o pkg/exf & thsice:
875      - for diagnostics purpose, fill-up and update Qsw array (+ fill the
876        diagnostics) even when SHORTWAVE_HEATING is #undef;
877    o verification/cfc_example:
878      - turn on pkg/layers with pkg/diagnostics (to test pkg/layers and to
879        illustrate how to use it).
880    o verification/offline_exf_seaice:
881      in input: add SEAICErestoreUnderIce=.TRUE., and reduce size of forcing
882        files to only one time-record.
883      in input.thermo: narrow the 2 bands of low initial ice-concentration near
884        N & S edges; switch on SEAICErestoreUnderIce=T; use pkg/diagnostics for
885        snapshot output; same mcPheePiston value as in thsice with
886        surf-current=0.2m/s.
887      in input.thsice: similar set-up as in input.thermo (channel with same seaice
888        initial conditions).
889    o verification/cfc_example:
890      - update file "data" with more standard choice (default rotationPeriod,
891        exactConserv=T, reduce ivdc_kappa to 10, remove multiDimAdvection=F,
892        set deltaTFreeSurf to deltaTtracer) and update the output.
893    o pkg/layers:
894      - fix bolus part so that it compiles with #undef GM_BOLUS_ADVEC;
895      - ensure that "layers_bolus" is switched to False when useGMRedi=False.
896    o verification/offline_exf_seaice:
897      - set all {field}period to zero for constant-in-time forcing (not tested
898        anywhere else).
899    o verification/offline_exf_seaice:
900      - dyn_lsr  : use pkg/seaice S/R (instead of pkg/thsice) to advect sea-ice;
901      - dyn_jfnk : use pkg/thsice S/R (instead of pkg/seaice) to advect sea-ice.
902    o model/src:
903      - implement Finite-Volume method for (hydrostatic) presure gradient
904        from S.-J. Lin (QJRMS 1997), for atmosphere using sigma-coordinate.
905    o pkg/seaice: implement EVP* by Lemieux et al. (2012).
906      - In order to be compatible with the default EVP code, this requires changing
907        the EVP code around a little; and because any small change immediately
908        breaks the lab_sea.hb87 verification experiment, the reference output is
909        updated two times (each time the remaining aggrement was only 2 digits):
910        - after replacing 1/dt by 1*recip_dt with a precomputed recip_dt
911        - after replacing 1/(1+0.5*dt/tau) by a/(a+1), with a=2*tau/dt
912        The adjoint test lab_sea.evp also needed to be updated.
913      - Turn on EVP* by setting SEAICE_deltaTevp as before, and setting
914        SEAICEuseEVPstar=.true.; for EVP* SEAICE_deltaTevp does not need to be
915        a factor of SEAICE_deltaTdyn, and you can set the number of EVP steps
916        explicitly with SEAICEnEVPstarSteps (thereby overriding the default of
917        INT(SEAICE_deltaTdyn/SEAICE_deltaTevp)). Controlling EVP* is deliberately
918        kept obscure, because I need to test it a little more.
919    o pkg/cheapaml:
920      - fix few incorrect type (_RL/_RS) in subroutine calls.
921    o pkg/seaice:
922      - new S/R SEAICE_MAP_RS2VEC (similar to SEAICE_MAP2VEC) to map _RS arrays
923        to _RL vector; this fixes JFNK code when compiling with "-use_r4" option.
924    o model/src:
925      - add a warning if using select_rStar=2 with nonlinFreeSurf <> 4;
926        change (in input_ad*/data) select_rStar from 2 to 1 for AD verification
927        experiments global_ocean.cs32x15 & tutorial_tracer_adjsens (+ update output)
928    o pkg/cheapaml:
929      - replace "273.1 _d 0" by celsius2K in pkg/cheapaml/cheapaml.F and
930        update output of experiment cheapAML_box.
931      - store in CHEAPAML.h coeffs ssq[0:2] for saturation specific humidity,
932        and set them only in one place (cheapaml_readparms.F).
933      - replace "273.16 _d 0" by celsius2K & replace "3.14159 _d 0" by constant "PI"
934      - remove re-setting of main-model parameter "celsius2K" (in cheapaml_readparms)
935        and re-setting of cheapAML params "lath" & "p0" (in cheapaml_init_varia).
936    o model/src/the_main_loop.F:
937      - fix revision 129 : need both ALLOW_ECCO and ALLOW_ECCO_EVOLUTION.
938    o pkg/seaice:
939      - remove legacy branch code.
940      - retire SEAICE_GROWTH_LEGACY and SEAICE_CAP_HEFF accordingly.
941    o verification/*/code*/SEAICE_OPTIONS.h:
942      - remove documentation for retired CPP flags (SEAICE_GROWTH_LEGACY,
943        SEAICE_CAP_HEFF).
944    o pkg/cheapaml:
945      - use standard routine (S/R GET_PERIODIC_INTERVAL) to decide when it is time
946        to load new forcing fields.
947      - add missing "_d 0" where it's needed; + some editing (improve indentation).
948      - remove switch to "-r8" compiler option (no longer needed) in verification
949        cheapAML_box, keep same output (small trucation error differences).
950    o verification/offline_exf_seaice:
951      - add thermodynamics only test.
952    o verification/cheapAML_box:
953      - split the domain in 8 (2x4) tiles; add MPI and multi-threaded test;
954        keep same output (same 14 digits for cg2d).
955      - switch on "-r8" compiler option (some numerical values are missing
956        the "_d 0") and update output (only 6 digits for cg2d were preserved).
957    
958    checkpoint64b (2012/12/24)
959    o pkg/cheapaml:
960      - remove un-used variables (Qnet,EmPmR) from pickup files.
961      - store tendency of advected variables into cheapaml pickup file
962        and fix the AB-2 restart.
963    o verification/offline_exf_seaice and lab_sea adjoint:
964      - switch to new code (#undef SEAICE_GROWTH_LEGACY).
965      - switch to 4 time steps in offline, consistent with lab_sea.
966      - match parameters from SEAICE_GROWTH_LEGACY branch in data.seaice.
967      - update results after change of experiment seaice.
968    o pkg/seaice:
969      - remove option SEAICE_MULTICATEGORY; has been replaced with run-time
970        parameter SEAICE_multDim. Issue a warning if SEAICE_MULTICATEGORY is
971        still defined since SEAICE_multDim needs to be set to MULTDIM value (from
972        SEAICE_SIZE.h) to recover previous #define SEAICE_MULTICATEGORY default.
973    o model/src:
974      - add run-time parameter to select CG2D solver minimum-residual solution
975        (in case of a poor convergence).
976    o pkg/seaice/seaice_lsr.F
977      - move calculation of matrix coefficients into new
978        S/R SEAICE_CALC_LSR_COEFFS; for now this routine remains in the same
979        file; the main purpose of this change is to be able to reuse the code
980        in S/R SEAICE_PRECONDITIONER
981      - modify the computation of the residual so that the mass of sea-ice
982        is not used twice; this simplifies the calculations, but since
983        the residual is never used except when LSR_mixIniGuess.ge.4---and this is
984        not tested in testreport---this does not affect the testreport results.
985    o verification/seaice_obcs:
986      - disable SEAICE_GROWTH_LEGACY; reset input files to match those of
987        verification/lab_sea/input.salt_plume; changes results/output.txt*
988    o model/src:
989      - adapt quasi-hydrostatic formulation to work with p or p* coordinate.
990    o pkg/seaice:
991      - improve description of parameters in seaice_fgmres.F and start
992        cleaning up the code
993      - change name of SCALPROD to SEAICE_SCALPROD and modify meaning of
994        second argument
995      - add a metric based on grid cell area to SEAICE_SCALPROD; update
996        results of offline_exf_seaice.dyn_jfnk
997      - compute initial residual norm in seaice_jfnk based on SEAICE_SCALPROD
998    o pkg/aim_v23:
999      - fix an other bug in dissipation heating (grid-cell area was missing).
1000    o model/src + pkg/seaice:
1001      - add global (multi-tile) linear solver for pair of tri-diagonal system
1002        along X and Y lines, respectively for U and V component.
1003        Note: 1) MPI and cube-exchange not yet coded.
1004            2) probably not accurate for poorly conditioned / large size problem.
1005      - add option for SEAICE_LSR to use global (multi-tile) tri-diagonal solver;
1006        default: not compiled and not used.
1007    o pkg/seaice:
1008      - first attempt at a multi-threaded fgmres solver for the JFNK solver:
1009        introduce bi/bj loops and use global_sum_tile_rl instead of
1010        mpi_allreduce in seaice_fgmres.F
1011      - improve diagnostics output for fgmres solver (seaice_fgmres.F)
1012      - replace a few unnecessary goto statements by if-blocks  (seaice_fgmres.F)
1013      - add a verification experiment for JFNK in offline_exf_seaice
1014    o verification:
1015      - change (for now, only fwd test) offline_exf_seaice experiment:
1016        use a re-entrant channel with idealized coastline (trapezoidal shape)
1017        at southern boundary to explore seaice dynamics and thermodynamics
1018        with simple forcing. Main set-up has dynamics+thermo and SST relaxation;
1019        secondary test (input.thsice) use thermodynamics only with SST relaxation.
1020      - add seaice-dynamics only secondary test using LSR and pkg/thsice advection.
1021    o pkg/exf:
1022      - disable "sstExtrapol" when Nr=1
1023    o verification:
1024      - add new experiment "cheapAML_box" (simple 1 layer set-up from Bruno Deremble)
1025        to test pkg/cheapaml.
1026    o pkg/aim_v23 & pkg/shap_filt:
1027      - fix dissipation heating (erroneous gravity multiplication factor).
1028    o pkg/seaice:
1029      - remove unused field pressPre from jfnk solver
1030      - rename two subroutines in seaice_preconditioner.F
1031    o eesupp/src:
1032       - S/R MDSFINDUNIT avoids reserved unit numbers (scrUnit1, eeDataUnit ...)
1033    o pkg/seaice/seaice_preconditioner.F: fix preconditioner once again
1034       - remove wrong parts of the rhs and the lhs (were in there
1035         because I did not understand the concept of this preconditioner)
1036       - add an exchange between u- and v-sweep. This increases communication
1037         by a factor of two but improves the convergence of jfnk. Ideally,
1038         one would like the u- and v-sweep to be independent. So far within
1039         undocumented ifdefs
1040       - reorganize the extra computations for printing the residuals
1041    o tools/genmake2:
1042      - comment out the "mpif.h" include in NetCDF test programm (for MPI built)
1043        since it's not necessary (and was preventing to use MNC in some cases).
1044    
1045    checkpoint64a (2012/11/16)
1046    o pkg/autodiff:
1047      - improve pkg-internal logical parameter switch (inAd/inFwd mode) so that
1048        autodiff_readparms.F no longer depends on calling order (within
1049        packages_readparms.F) and no longer requires to include ${PKG}_PARMS.h):
1050        rename param turnFreeDriftInAdMode to SEAICEuseFREEDRIFTswitchInAd
1051        and change param SEAICEuseDYNAMICSinAdMode to SEAICEuseDYNAMICSswitchInAd.
1052    o pkg/obcs:
1053      - adding tidal velocity forcing capability to obcs
1054        for usage example, see verification/seaice_obcs/input.tides
1055    o pkg/seaice:
1056      - turn the LSR-relaxation parameters WFAU/V into runtime parameters
1057        SEAICE_LSRrelaxU/V
1058      - introduce runtime parameter SEAICEetaZmethod (=0 by default)
1059    o pkg/aim_v23:
1060      - implement heating from friction (bottom friction and stratospheric drag).
1061    o pkg/shap_filt:
1062      - fix diagnostic "SHAP_dKE" (was 2 time smaller); implement heating from
1063        dissipation but only for Shap_funct=2, active when addFrictionHeating=T.
1064    o model/src:
1065      - move AddMass common block from DYNVARS.h to FFIELDS.h; allow to read-in
1066        time-constant addMass field from file (addMassFile);
1067      - support for heating due to friction (and Kinetic Energy dissipation):
1068        add option, run-time switch and 3-D field array + support code ; each pkg
1069        or S/R can add heating contribution (if there is a sink of KE); the sum is
1070        accounted for as a Temperature tendency term (EXTERNAL_FORCING_T).
1071    o pkg/seaice:
1072      - complete merge of ITD code into seaice_growth.F
1073        from MITgcm_contrib/torge/itd/code/
1074        no verification so far, but Torge Martin tested
1075        "1-D test case and Beaufort set up;
1076        deliver okay results after 1 model year."
1077      - complete merge of SEAICE_SIZE.h into all relevant routines
1078      - move computation of eta at Z-points into calc_viscosities
1079        + introduce global field etaZ
1080        + add different methods for computing etaZ, for now the old
1081          method (simple averages of eta to Z-points) is hardwired
1082        + replace etaMeanZ by etaZ in seaice_lsr, seaice_calc_residual,
1083          seaice_preconditioner
1084      - simplify computations for SEAICE_ZETA_SMOOTHREG
1085      - seaice_preconditioner:
1086        + replace one remaining press by pressLoc (mistake)
1087        + adjust printing of residuals
1088      - improve I/O of diagnostics of JFNK in seaice_jfnk.F:
1089        + add (SEAICE.h) and rename some counters (initiliased in
1090          seaice_init_fixed.F)
1091        + add _BEGIN/END_MASTER (myThid)  around print statements
1092        + print total number of iterations and failures over SEAICE_monFreq
1093          interval to STDOUT
1094      - move control over output-messages by fgmres to seaice_jfnk to save
1095        some operations
1096      - move resetting initial guess for fgmres outside of seaice_fgmres_driver
1097        in order to make restarts with sol .ne. zero (fgmres with restarts)
1098        (seaice_jfnk.F, seaice_fgmres.F)
1099      - seaice_calc_l/rhs.F: replace maskW/S by maskInW/S; this fixes
1100        a serious convergence problem when open boundaries are involved
1101    o pkg/ggl90: fix computation of control volumes for the case of
1102      ALLOW_GGL90_HORIZDIFF (probably not used very often): move control volumes
1103      up half a grid cell from C-centered to W-centered (pointed out by C. Eden)
1104    o pkg/seaice: simplify seaice_evp by avoiding use of extra fields u/vIceC
1105    o pkg/autodiff
1106      - Add inAdMode switch for SEAICEuseDYNAMICS:
1107        SEAICEuseDYNAMICSinAdMode
1108        (extend logic in ADAUTODIFF_INADMODE_SET)
1109    o pkg/seaice
1110      - Step 1 of merging ice-thickness distribution (ITD) code from
1111        MITgcm_contrib/torge/itd/ (author: Torge Martin)
1112        The code implements concept laid out in Thorndike et al. (1975);
1113        code is enabled via CPP flag SEAICE_ITD
1114        nITD (in SEAICE_SIZE.h) defines number of ice thickness categories;
1115        code is not complete yet!!
1116      - SEAICE_SIZE.h now included in almost all seaice routines
1117    o verification (using seaice):
1118      - switch back seaice-dynamics (+ lower SOLV_MAX_ITERS) in ADM exp.
1119        global_ocean.cs32x15.seaice ; update results.
1120      - compile B-grid dynamics in FW test exp 1D_ocean_ice_column ;
1121      - compile C-grid dynamics with #define SEAICE_ALLOW_JFNK in FW test exp
1122        offline_exf_seaice (previously compiling B-grid).
1123    o pkg/exf:
1124      - fix some STOP conditions in exf_check.F (from Aug 28, modifs did not allow
1125        to specify neither just 1 comp of wind or wind-stress, nor no surface momentum
1126        forcing): just replace CPP option ALLOW_ATM_WIND with run-time param useAtmWind.
1127    o pkg/layers (adjust changes from Sept 19):
1128      - do snap-shot output and fill diagnostics from inside iLa loop (layers_calc.F)
1129        this allows to remove "layers_maxNum" dimension from all layers arrays.
1130    o pkg/layers (adjust changes from Sept 19):
1131      - remove ALLOW_LAYERS_OUTPUT ; fix snap-shot and time-ave output ;
1132      - snap-shot extended to all type of layers (not just the 1rst type);
1133      - remove layers variables when corresponding CPP option is undef.
1134    o pkg/layers:
1135      - rename pkg/layers variable and add new output (layer exist & un-weighted
1136        velocity in layer)
1137    o pkg/seaice:
1138      - simplify (?) ocean-drag coefficent computations by using
1139        the same routine in all three solvers (saves some code lines)
1140      - remove global fields DRAGA and DRAGS from C-grid code and
1141        declare them locally in lsr.F (the only place where they are
1142        still used)
1143      - update AD output of lab_sea.evp (very sensitive anyway).
1144    o pkg/seaice: add Jacobian-free Newton Krylov solver for ice dynamics
1145      (Lemieux et al. 2010, 2012). Turn on with the usual SEAICE_ALLOW_JFNK
1146      and SEAICEuseJFNK=.true. A few things to note:
1147      - involves a FGMRES, that is parallel but very inefficient,
1148        because of many scalar products (global sums) in the Gram-Schmidt
1149        orthogonalization method. Needs to be replaced. Original code
1150        from J.-F. Lemieux
1151      - preconditioner for FGMRES is a stripped down version of LSOR
1152      - SOLV_MAX_ITERS is now used for LSOR as a solver and as a
1153        preconditioner. For the preconditioner, the default is set to 10.
1154      - Jacobian times vector is computed with finite differences
1155      - marginally related to JFNK-solver: add a smooth regularization for
1156        zeta with tanh that will improve convergence (Lemieux and Tremblay,
1157        2009) for any implicit solver (not implemented for EVP because EVP
1158        does not need this regularization in the first place). Define
1159        SEAICE_ZETA_SMOOTHREG in SEAICE_OPTIONS.h to use.
1160    o eesupp/src:
1161      - check in genmake2 that intrinsic S/R flush is available.
1162      - add S/R to flush IO unit (if intrinsic S/R flush is available)
1163      - flush standard & error msg unit before MPI termination
1164      - if debugMode, flush IO unit after printing msg
1165    o pkg/ctrl:
1166      - ctrl_unpack.F, ALLOW_GENARR3D_CONTROL code: fix missing argument in call
1167        to ctrl_set_unpack_xyz.
1168    
1169    checkpoint64 (2012/10/09)
1170    o pkg/shelfice
1171      - in mom_fluxform.F, mom_vecinv.F:
1172        CALL SHELFICE_V_DRAG(bi,bj,k,vFld,KE,KappaRU,vF,myThid)
1173        Bug fix KappaRU -> KappaRV
1174        does not change verification/isomip but may change other setups
1175        (presumably constant KappaRU=KappaRV)
1176      - fix diagnostics SHIU/Vdrag (thanks to Tom Millgate)
1177    o pkg/obcs:
1178      - fixed some indexing bugs in obcs_seaice_sponge.F
1179      - added obcs relaxation subroutines for HSALT and HSNOW
1180      - changes verification/seaice_obcs/results/obcs_seaice_sponge.F
1181    o pkg/seaice:
1182      - add "multicategory" parameterization for snow in analogy to ice,
1183        default is off for now.
1184    o pkg/obcs:
1185      - added obcs_seaice_sponge.F for obcs relaxation of seaice variables;
1186        see verification/seaice_obcs/input.seaiceSponge for example application.
1187      - remove local commom bloc "OBCS_GLOBAL" in obcs_readparms.F and do all the OB
1188        index setting by master-thread. This fix multi-threads Pb in previous modifs.
1189    o pkg/layers :
1190      - add diagnostics to pkg/layers
1191      - move the meat of pkg/layers from layers_calc.F to layers_fluxcalc.F
1192        (from R.Tulloch). Layers_calc.F now calls layers_fluxcalc.F accordingly.
1193    o pkg/generic_advdiff/gad_implicit_r.F :
1194      - fix ADVr diagnostics in case of both implicit vertical advection and diffusion.
1195    o pkg/seaice/seaice_growth.F:
1196      - fix SItflux diagnostics in virtual salt flux + balanceEmpmr case.
1197    o pkg/obcs:
1198      - change default setting of OBCS_UVICE_OLD from defined to undef;
1199      - use new parameter OB_indexNone for null index value (instead of hard-coded 0)
1200        in all pkg/obcs code and in other pkgs; remove k loop in obcs_check_depths.F;
1201      - pass OB_indexNone as (new) argument to S/R CTRL_MASK_SET_[X,Y]Z;
1202      - change OB null index value (OB_indexNone) to -99 ; this fix the problem
1203        with Southern & Western OB at a tile edge (at least in a simple set-up).
1204    o pkg/obcs:
1205      - change settings of OB index in case OB coincides with tile edge (shared by
1206        2 tiles), so that common OB location is registered by both tiles (instead of
1207        only 1). However, for Southern and Western OB, index value = 0 is not
1208        recognized as valid OB index (=default null value) and needs to be fixed.
1209      - modify accordingly OBCS_BALANCE_FLOW and OBCS_MONITOR (avoid double counting)
1210      - new parameter "OB_indexNone" for null index value (for now, still zero)
1211        to replace hard-coded null index value of zero.
1212    o pkg/exch2:
1213      - improve W2_USE_E2_SAFEMODE (faster) and W2_E2_DEBUG_ON:
1214        always check buffer-size (but outside the loop); move checking for valid
1215        index from W2_USE_E2_SAFEMODE to W2_E2_DEBUG_ON; in W2_E2_DEBUG_ON,
1216        print each tile and point connection only if |W2_printMsg|>= 2 and 3.
1217    o pkg/ctrl (pack & unpack):
1218      - in ctrl_pack.F & ctrl_unpack.F, use the same local file-name variable
1219        (locally defined) for different variables (+ remove the variable-specific
1220        file name in CTRL_GENARR.h). For now, only implemented for GENARR2/3D_CONTROL
1221        (to be extended to other local file names in ctrl.h).
1222    o pkg/flt:
1223      - add a FLT_Iter0 option (similar to PTRACERS_Iter0).
1224    o pkg/mdsio:
1225      - fix missing STOP in mdsio_readvec_loc.F (case ioUnit=0) when file is missing
1226    o tools/genmake2:
1227      - add similar dependences for target EXE_AD & EXE_FTL as we have for EXECUTABLE
1228        (added by Alistair in version 1.51 for building without make depend);
1229      - remove Header files list (H_SRC_FILES) from the dependence of targets
1230         ad_input_code.f & ftl_input_code.f (not clear why it was added in the first
1231        place in version 1.23): this save going through staf when unrelated header
1232        file has been modified.
1233       Note: for an intermediate target (e.g., ad_input_code.f or adtaf) without
1234        "make depend" step, still need to do "make links" before "make adtaf".
1235    o eesupp/src (+ few pkg src files) & genmake2:
1236      - finish to remove ALWAYS_USE_MPI in source code that TAF does not see;
1237      - no longer set ALWAYS_USE_MPI in Makefile (was done by genmake2).
1238      - improve genmake2 checking for ALLOW_${PKG} in CPP_OPTIONS.h files (distinguish
1239         upper/lower case ; account for space between "#" and undef/define)
1240    o pkg/flt (with exch2):
1241      - cleaning: fix so that it compiles; move remaining MPI calls out of flt_exch2.F;
1242      - simplify threads synchronisation; fix (many issues) multi-threaded with MPI.
1243    
1244    checkpoint63s (2012/09/05)
1245    o pkg/ecco:
1246      - remove #ifdef ALLOW_SMOOTH_CORREL3D brackets.
1247      - add more relevant #ifdef ALLOW_SMOOTH ones.
1248      - sort out useAtmWind, useSMOOTH, ctrlSmoothCorrel2D.
1249    o pkg/ctrl:
1250      - CTRL_OPTIONS.h : document CPPs related to smoothing; ALLOW_SMOOTH_CORREL2D/3D,
1251        ALLOW_CTRL_SMOOTH, ALLOW_SMOOTH_CTRL2D, ALLOW_SMOOTH_CTRL3D.
1252      - ctrl.h : document run time params doInitXX, doMainPack, doMainUnpack, doPackDiag,
1253        doSinglePrecTapelev (audodiff param!), ctrlSmoothCorrel2D (new) and
1254        ctrlSmoothCorrel3D (new).
1255        The added ctrlSmoothCorrel2D/3D replace the old ALLOW_SMOOTH_CORREL2D/3D CPP.
1256      - ctrl_readparms.F : initialise ctrlSmoothCorrel2D/3D and read from namelist.
1257      - ctrl_init.F ctrl_pack.F ctrl_unpack.F : switch off ustress/vstress
1258        controls when useAtmWind, and vice versa.
1259      - ctrl_map_ini_ecco.F : UVEL0, VVEL0, edtaux, edtauy cannot be smoothed as tracers.
1260      - ctrl_get_gen.F : replace #ifdef ALLOW_SMOOTH_CORREL2D with
1261          #ifdef ALLOW_SMOOTH, IF ctrlSmoothCorrel2D, IF useSMOOTH.
1262      - ctrl_map_ini_gen.F : replace #ifdef ALLOW_SMOOTH_CORREL3D with
1263          #ifdef ALLOW_SMOOTH, IF ctrlSmoothCorrel3D, IF useSMOOTH.
1264      - ctrl_set_pack_xy[z].F, ctrl_set_unpack_xy[z].F:
1265        replace ALLOW_SMOOTH_CORREL2D/3D brackets with ctrlSmoothCorrel2D/3D.
1266    o pkg/smooth:
1267      - remove un-necessary includes.
1268      - remove ALLOW_SMOOTH*D and ALLOW_SMOOTH_CORREL*D brakets.
1269        Those CPP options were never defined, and not necessary.
1270    o model/src:
1271      - fix CPP brackets in ini_mixing.F (GM_background_K belongs to gmredi).
1272      - standard treatment of useSMOOTH.
1273    o pkg/autodiff:
1274      - add LOGICAL useGGL90inAdMode, useGGL90inFwdMode, useSALT_PLUMEinAdMode,
1275        useSALT_PLUMEInFwdMode allowing to switch off ggl90 and salt_plume adjoint.
1276    o pkg/exch2:
1277      - add "if usingMPI" where it was missing (in exch2_rx?_cube*.template)
1278        + start to remove ALWAYS_USE_MPI in source code that TAF does not see.
1279      - make new S/R W2_MAP_PROCS out of w2_eeboot.F to setup exch2 CommonFlag
1280        and tiles to process mapping.
1281      - re-arrange 3 header files (W2_EXCH2_PARAMS.h, _BUFFER.h & _TOPOLOGY.h)
1282        moving /EXCH2_FILLVAL_RX/ & /W2_EXCH2_COMMFLAG/ to W2_EXCH2_TOPOLOGY.h;
1283        rename "exch2_tProc" to "W2_tileProc" and move seting of e2FillValue_RX
1284        from w2_eeboot.F to w2_readparms.F.
1285    o eesupp/src:
1286      - set exchNeedsMemsync & exchUsesBarrier according to "usingMPI" (instead of
1287        ALWAYS_USE_MPI) + moved from ini_communication_patterns.F to eeset_parms.F;
1288        also move setting of exchCollectStatistics from exch_init.F to eeset_parms.F
1289      - in eedie.F and all_proc_die.F, always call MPI_FINALIZE when ALLOW_USE_MPI
1290        is defined (remove condition on usingMPI) to match cases where MPI_INIT
1291        has been called.
1292      - fix bug I put in previous modif of exch_sm_3d_rx.template (not much used);
1293      - change default (non-MPI) value of myPid (from 1 to 0) to match MPI settings
1294        (so that on 1 proc, get same myPid independently of usingMPI)
1295      - add a stop if multi-procs but usingMPI=F ; stop also if usingMPI=T and
1296        useCubedSphereExchange with EXCH-1 (safer).
1297      - add "if usingMPI" where it was missing (+ start to remove ALWAYS_USE_MPI).
1298    o pkg/ggl90:
1299      - fix bug in filling corner mask array "mskCor" (FILL_CS_CORNER_TR_RL call)
1300        used in ALLOW_GGL90_SMOOTH code.
1301    o pkg/flt:
1302      - fix typo in FLT_WITHOUT_Y_PERIODICITY (the effect was to ignore stopping
1303        floats at the Southern end of the domain).
1304    o eesupp/inc:
1305      - add a list of CPP-options which can be set by Makefile (DEF_IN_MAKEFILE.h);
1306        but not used (and not to be used) anywhere, just for documentation.
1307    o pkg/autodiff, exf, ptracers & seaice (AD & TL output):
1308      - comment out the very nasty "writeBinaryPrec = writeStatePrec" line, since:
1309        a) can damage previously written records in any other multi-record files.
1310        b) if needed, can easily do it cleanly, by calling S/R WRITE_REC_3D_RL/S.
1311    o tools/genmake2:
1312      - define variable MAKE within Makefile and use it in place of 'make';
1313      - update AD_CONFIG.h (if needed) before building any of the executable
1314        (forward, adjoint or tangent-lin); this involves a 2nd invocation of make;
1315        and add the usual #ifndef/#define AD_CONFIG_H in AD_CONFIG.h;
1316      - always print usual warning comment 'this file is automatically generated'
1317        from script convert_cpp_cmd2defines (+ remove this warning from genmake2).
1318    o pkg/cheapaml:
1319      - updated to correspond to the code used in accepted paper (Nico Wienders).
1320    o pkg/exf:
1321        added run time switch useAtmWind to replace ALLOW_ATM_WIND cpp switch.
1322        ALLOW_ATM_WIND now just sets the useAtmWind default (see exf_readparms.F)
1323        and force defines ALLOW_BULKFORMULAE (EXF_OPTIONS.h).
1324    o pkg/exf, autodiff, ctrl, ecco and seaice:
1325        remove ALLOW_ATM_WIND brackets, or replace them with useAtmWind ones.
1326    o pkg/ctrl, ecco:
1327        allow to compile both ALLOW_U/VSTRESS_CONTROL and ALLOW_U/VWIND_CONTROL.
1328        Depending on useAtmWind, one is inactive, and the other is active (see
1329        exf_getffields.F/exf_getsurfacefluxes.F).
1330    o tools/genmake2:
1331      - improve error msg when failing in 2nd test of check_for_broken_Ff
1332      - fix option '-makefile' short-name (-mf according to genmake2 -help)
1333      - source local config file "genmake_local" just after processing the genmake2
1334        command arguments (previously done before processing arg).
1335    o pkg/grdchk:
1336      - add a call to TURNOFF_MODEL_IO for Tangent-Linear run (in this case, call
1337        to this routine from cost_final has been dropped in g_cost_final)
1338      - improve printed information (more explicit msg, no longer using "print *,"
1339         fix fcpertminus printed value).
1340    o model/src:
1341      - move call to COST_INIT_VARIA out of packages_init_variables.F directly
1342        into initialise_varia.F (just after calling PACKAGES_INIT_VARIABLES):
1343        this prevents getting cost-funct reset in adinitialise_varia recomputations.
1344    o pkg/dic:
1345      - move initialisation of "freefe" array from from dic_biotic_forcing.F to
1346        fe_chem.F: this prevents TAF from dropping this initialisation in TLM code.
1347    o pkg/grdchk:
1348      - grdchk_main.F : added CALL GLOBAL_SUM_INT( ierr , myThid )
1349      - grdchk_getadxx.F etc. : omit I/O if ierr.EQ.0
1350    o pkg/autodiff/ctrl/grdchk :
1351      - attempt to sort out what works and what does not,
1352        with regard to I/O, and to warn/stop accordingly.
1353    o pkg/grdchk:
1354      - attempt to fix grdchk in the case of useSingleCpuIO.
1355      - "if ( myProcId .EQ. grdchkwhichproc .AND. ierr .EQ. 0 )"
1356       statements were moved from grdchk_main.F and into
1357       grdchk_getadxx.F grdchk_getxx.F grdchk_setxx.F.
1358      - a global sum is applied to record numbers icvrec/layer
1359       out of grdchk_loc so that they be passed to I/O routines.
1360    o pkg/smooth:
1361      - fix recomputation that appeared with nlfs : use smooth_recip_hFacC,
1362        smooth_hFacW, smooth_hFacS (copied at init_fixed) in 3d case.
1363    o verification/testreport:
1364      - add option '-tlm' for Tangent-Linear test (-adm,-oad,-tlm are all exclusive);
1365      - can also use compressed (gzip) reference output file;
1366      - change format (in pkg/grdchk) of TLM output (+ add forward gradient)
1367        to be easier to collect by testreport.
1368      - update existing TLM output (half out-of-date by more than 3 yrs).
1369      - report NETCDF & LAPACK settings (from genmake2) in output dir.
1370      - report run-time in each individual summary (previously only for AD test);
1371        for TLM test, add also TAF version.
1372      - add daily TLM test on (old) aces cluster + weekly test on baudelaire.
1373    
1374    checkpoint63r (2012/08/15)
1375    o tools/genmake2:
1376      - fix Makefile for target ftlall (+ update files to clean after make ftlall)
1377    o pkg/ecco/ecco_cost_final.F :
1378      - fix fc print statements (to stdout and costfunction0000) so
1379        that the printed value is always after the global sum.
1380    o pkg/seaice/seaice_dynsolver.F :
1381      - fix ice strength assymptote at SEAICE_area_max<1
1382        (no change for the standard case of SEAICE_area_max=1)
1383    o some cleaning:
1384      - pkg source files: ensure that all *.F files from each pkg included the
1385        corresponding ${PKG}_OPTIONS.h file (except stand-alone src file which
1386        only includes CPP_EEOPTIONS.h); fix S/R CTRL_SMOOTH ; update AD experiment
1387        code_ad/*.F src files; add new option-file in pkg/admtlm + corresponding
1388        includes;
1389      - model/src: add PACKAGES_CONFIG.h wherever ALLOW_AUTODIFF[_TAMC] is used.
1390      - ALLOW_DIFFKR_CONTROL: add a stop in S/R CTRL_CHECK in case ALLOW_3D_DIFFKR
1391        is undef; also define /DYNVARS_DIFFKR/ common block in DYNVARS.h when
1392        ALLOW_DIFFKR_CONTROL is defined, to allow to compile and reach this stop.
1393      - update option-file CPP_OPTIONS.h of all AD experiments:
1394        * no longer include PACKAGES_CONFIG.h ;
1395        * includes ECCO_CPPOPTIONS.h if PACKAGES_CONFIG.h has been included ;
1396        * def/undef ALLOW_3D_DIFFKR independently of ALLOW_DIFFKR_CONTROL (before
1397          including ECCO_CPPOPTIONS.h).
1398    o pkg/cost, pkg/ctrl, pkg/ecco option-file:
1399      - clean-up and split content of old pkg/ecco/ECCO_CPPOPTIONS.h file into
1400        separated pkg option-file (done according to old doc from ECCO_CPPOPTIONS.h,
1401        not necessary accurate).
1402      - add a template for option-file ECCO_CPPOPTIONS.h, mostly empty, in
1403        pkg/autodiff, i.e., the 1rst pkg to compile for adjoint built, with lines to
1404        deliberately break compilation (a remainder that it needs to be customized)
1405      - in pkg/ecco, includes ECCO_OPTIONS.h instead of COST_OPTIONS.h
1406      - rename COST_CPPOPTIONS.h to COST_OPTIONS.h
1407      - rename CTRL_CPPOPTIONS.h to CTRL_OPTIONS.h
1408    o tools/genamke2:
1409      - check for lapack.
1410    o pkg/cost and pkg/ecco : attempt to sort out some of the limiting intricacies.
1411      - pkg/cost.cost_final.F : allow for use of pkg/ecco and pkg/cost cost functions
1412        jointly. The exclusive ifdefs were removed, to add costs terms (when defined)
1413        from both packages.
1414      - the fc global sum in pkg/ecco/ecco_cost_final.F was removed accordingly.
1415      - for objf_atl we use either the pkg/ecco or the pkg/cost term depending on CPPs.
1416      - pkg/ecco and model/src : add CPP brackets around pkg/cost and pkg/ctrl includes
1417        of "CTRL_SIZE.h" "ctrl.h" "ctrl_dummy.h" "optim.h" / "cost.h" accordingly.
1418    o pkg/cost : add comments to explain special and/or untested setups.
1419    o pkg/exf:
1420      - use EXF_OPTIONS.h to set pkg/exf options except if done in ECCO_CPPOPTIONS.h
1421        (previously, ALLOW_AUTODIFF_TAMC was controling this switch).
1422    o verification/*/code_ad:
1423      mimimal cleaning of AD experiments ECCO_CPPOPTIONS.h option-file:
1424      - reccord when this file is included (define ECCO_CPPOPTIONS_H)
1425      - remove the most obvious obsolete features (e.g., #define ALLOW_COST not
1426        allowed since Oct 2003 in any option-file except in PACKAGES_CONFIG.h)
1427    o pkg/seaice :
1428      - added possibility to change ice strength/PRESS0 relationship to
1429        HEFF, according to the following run time parameters
1430        SEAICEpresPow0 :: HEFF exponent for ice strength below SEAICEpresH0 (integer, >0)
1431        SEAICEpresPow1 :: HEFF exponent for ice strength above SEAICEpresH0 (integer, >0)
1432        SEAICEpresH0   :: HEFF threshold for ice strength            (m)
1433    o pkg/ggl90 :
1434      - added run time flag mxlSurfFlag to include the code that ensure
1435        mixing between first and second level (previously included as a comment)
1436    o verification/1D_ocean_ice_column/input_ad/data.autodiff :
1437      - add test of newly added dumpAdByRec=T option where
1438        we write all records to one file per variable.
1439    o verification/global_ocean.cs32x15/code_ad/CPP_OPTIONS.h :
1440      - switch to #define ALLOW_BALANCE_RELAX and ALLOW_BALANCE_FLUXES
1441        to check that this code is ok with taf and compiles in adjoint.
1442    o pkg/autodiff :
1443      - added run time param dumpAdByRec : ad dump format switch.
1444        If true then write all records to one file per variable.
1445        Else write one file per record (remains the default).
1446      - revise seaice_ad_dump.F and exf_adjoint_snapshots_ad.F accordingly.
1447    o pkg/seaice:
1448     - Added SEAICEuseTILT run time switch : if set to
1449       false then omit the tilt term in seaice dynamics.
1450     - Fix free drift calculation.
1451    o pkg/shelfice:
1452      When initializing SHELFICEDragQuadratic, set default to be
1453      consistent with shiCdrag in case SHELFICEuseGammaFrict is used,
1454      but retain option to set it independently
1455      (inconsistenty spotted by Veronique Dansereau)
1456    o eesupp/inc:
1457      - in EEPARAMS.h, add real-type constant for some frequently used simple number
1458         (0,1,2,1/2), with name explicitly referring to RS/RL type.
1459    o model/src:
1460      - move balancing of relaxation terms to new S/R balance_relax.F.
1461    o pkg/autodiff:
1462      re-write active I/O high-level (control) S/R:
1463      - rename  S/R ACTIVE_READ/WRITE_RL to ACTIVE_READ/WRITE_3D_RL
1464      - add 1 more argument (useCurrentDir) to replace the "_LOC" 2nd set of S/R.
1465      - use standard pkg/mdsio I/O routines (MDS_READ/WRITE_SEC_XZ/YZ  and
1466        MDS_READ/WRITE_FIELD); change loops to multi-threads.
1467      - update and merge active_file_control_slice.flow into active_file_control.flow
1468      - update the calls in lower level S/R (active_file.F, active_file_g.F and
1469        active_file_ad.F) keeping the argument list and function unchanged.
1470      - also update lower-level "_LOC" version (call same S/R with "useCurrentDir
1471        =.TRUE.") and remove high-level (control) _loc version (not called anymore).
1472      - new low-level active I/O routines, one for each type (RL/RS), for active var
1473        of various (XY,XZ,YZ) shape and level number (arguments: arrShape, myNr);
1474        fix ctrl_init_wet.F & ecco_cost_weights.F by calling the new S/R with the
1475        right type.
1476    o autodiff and RS=real*4:
1477      - call the right type (_RS instead of _RL) of S/R in few output S/R (pkg/exf
1478        ad-monitor and snapshots); disable arrType='RS' in mdsio_gl*.F ;
1479      - change argument type of 3-D mask argument to _RS to match type in the call
1480        (in seaice_cost*.F, ctrl_*_gen.F and *ctrl_bound.F); to be continued.
1481    o pkg/thsice:
1482      - re-anable balanceEmPmR when useSEAICE=T with useThSIce=T.
1483      - option to correct ocean fresh-water flux for imbalance of Atmos+Land
1484        fresh-water flux: uniform correction or proportional to local precip.
1485    o pkg/ctrl:
1486      - new header file CTRL_SIZE.h for parameters maxCtrlArr2D, maxCtrlArr3D
1487      - redefine CPP option ALLOW_BOTTOMDRAG_CONTROL to
1488                            ALLOW_BOTTOMDRAG_CONTROL_NONGENERIC
1489      - verification/hs94.1x64x5/ tests ALLOW_GENARR{2D,3D}_CONTROL
1490    
1491    checkpoint63q (2012/07/30)
1492    o pkg/autodiff:
1493      note about monitor and snap-shot of ad-variables:
1494      a) need to apply ADEXCH before monitor or output of ad-vars to include
1495       overlap contributions (was done for adjDump but missing for monitor).
1496      b) since ADEXCH implies adding overlap values to interior array, machine
1497       truncation error is expected when adding an ADEXCH call in the middle of
1498       the time-stepping (although mathematically identical).
1499      modifs:
1500      - fix some incorrect type (RL/RS, UV/scalar) in ADEXCH calls and ad-vars
1501        declaration (adEddyPsiX,adEddyPsiY in adcommon.h).
1502      - add new run-time params (dumpAdVarExch & mon_AdVarExch) to select how  to
1503        apply ADEXCH before monitor or snap-shot of ad-variables:
1504           =0 : no ADEXCH ; =1 : do ADEXCH ; =2 : apply ADEXCH on a local copy.
1505      - implement new method (copy+adexch) for snap-shot and monitor of main model
1506        ad-vars (initially not used by default -> output unchanged).
1507      - change default (set to 2) to use new method and update few output_adm.txt
1508        with accurate ad-monitor (global_ocean.90x40x15, tutorial_global_oce_biogeo
1509        and both tutorial_tracer_adjsens tests).
1510      - switch 2 global_ocean.cs32x15 AD-tests to AB-2 (seaice_dynmix & thsice)
1511        and turn off momDissip_In_AB in the 2 other (needed for stable AB-3).
1512    o pkg/ctrl:
1513      enable the use of a variable number (maxCtrlArr2D, maxCtrlArr3D) of
1514      generic control variables via
1515      #define ALLOW_GENARR2D_CONTROL and/or #define ALLOW_GENARR3D_CONTROL
1516      Only required customization should be S/R ctrl_map_ini_genarr.F
1517      (routine in repository contains example)
1518    o pkg/exf:
1519      - fix and refine checking of surface-relaxation setting when using EXF
1520    o verification (adjoint exp):
1521      - reduce length of simulation by half for experiment global_ocean.cs32x15
1522        (std, seaice & seaice_dynmix) and exp tutorial_dic_adjoffline; update output.
1523    o pkg/mom_common (mom_u/v_bottomdrag), pkg/shelfice (shelfice_u/v_drag)
1524      - replace if statements KE.ne.0 with KE.gt.0 to avoid sqrt of negative numbers
1525        of KE that can occur with aggressive optimization
1526      + put quadratic bottom drag calculation in separated loops (only done if
1527        using bottomDragQuadratic)
1528    o model/src: CG2D_NSA
1529      - clean-up:  stop if cg2dNormaliseRHS=T and AUTODIFF
1530         and replace GLOBAL_SUM calls with GLOBAL_SUM_TILE.
1531      - in test-exp that uses CG2D_NSA (bottom_ctrl & tutorial_tracer_adjsens),
1532         change cg2d residual target to be expressed in Wunits (=> do not normalise
1533         RHS ; this fix global_max Pb with TAF); update output.
1534    o verification/tutorial_tracer_adjsens:
1535       improve parameter consistency (and get rid of warnings):
1536       - use deltaTFreeSurf=deltaTtracer (better with NonLin FreeSurf);
1537       - switch Temp Adv Scheme from 81 to 80 (no limiter since theta < 0 is physical)
1538       - use staggerTimeStep (for stability) in som81; use default rotation period.
1539    o pkg/exch2:
1540      - with empty facet: fix compact-format (W2_mapIO=1) definition (was previously
1541        reset to 0 = 1 long line in X)
1542    o pkg/mdsio:
1543      - fix reading of dimensions from meta file for large-size domain
1544    o model/src:
1545      - fix saltIsActiveTr setting for IdealGas eosType (eosType is 6 character long);
1546      - to refine CS-grid check, add logical flag "hasWetCSCorners": true if using
1547        Cubed-Sphere Exch with CS-corners inside the domain;
1548        make new S/R INI_GLOBAL_DOMAIN from code in ini_linear_phisurf.F to calculate
1549        globalArea and to set hasWetCSCorners.
1550      - add warning if usingCurvilinearGrid and momAdvection in flux-form (missing
1551        metric terms); stop if hasWetCSCorners=T and momAdvection in flux-form.
1552      - re-activate the stop if useCDscheme and hasWetCSCorners=T (previously if
1553        useCDscheme and useCubedSphereExchange).
1554    o pkg/seaice/seaice_growth.F :
1555      - compute the SEAICE_DISABLE_HEATCONSFIX term accordingly
1556        for the (.NOT.useRealFreshWaterFlux).OR.(nonlinFreeSurf.EQ.0)
1557        when the previous code was not correct.
1558      - in all cases diagnoze the boundary condition mismatch to SIaaflux
1559      - in the case of useRealFreshWaterFlux.AND.(nonlinFreeSurf.GT.0) add
1560        that term to QNET (essentially to set the melt/freeze water to 0degC).
1561        when SEAICEheatConsFix is true, so that the ocean+ice budget heat is closed.
1562    o verification/global_ocean.cs32x15/input.seaice :
1563      - add SEAICEheatConsFix in data.seaice, ensuring closed ocean+ice heat budget.
1564      - add diagnostics (commented out) for budget test using my matlab codes (gcmfaces).
1565      - update results (output.seaice.txt) accordingly.
1566    o verification/lab_sea/input/data.seaice :
1567      - remove SEAICEheatConsFix, which is now be tested
1568        in global_ocean.cs32x15. The presently coded fix
1569        is only consistent with real fresh water + nlfs.
1570      - update results (output.txt) accordingly.
1571    o pkg/salt_plume: added diagnotic for salt tendency (oceSPtnd).
1572    o AD_CONFIG.h file:
1573      - in genmake2: remove "#undef ALLOW_ECCO_OPTIMIZATION" from AD_CONFIG.h;
1574      - remove #include "AD_CONFIG.h" from all included OPTIONS files and
1575        add it explicitly in each fortran src file where it is needed.
1576        motivation: header file AD_CONFIG.h is generated/modified after "make depend"
1577        thus introducing potentially wrong dependency; therefore, better to include
1578        it only where it's really needed, and after any other included OPTIONS file
1579        (less tempting to bring conditional includes according to ALLOW_ADJOINT_RUN
1580        or ALLOW_TANGENTLINEAR_RUN).
1581    
1582    checkpoint63p (2012/07/06)
1583    o pkg/autodiff:
1584      - rename S/R INI_AUTODIFF to AUTODIFF_INIT_VARIA ;
1585      - create new header file "AUTODIFF_PARAMS.h" for pkg/autodiff parameters
1586        which are now read from new parameter file "data.autodiff" (inAdExact
1587        previously in "data", use{KPP/GMRedi/SEAICE}inAdMode previously in data.pkg)
1588      - add file "data.autodiff" in all verification/*/input_ad/ directories.
1589      - add run-time parameter to turn On/Off SEAICEuseFREEDRIFT in adjoint/forward
1590        mode (used in global_ocean.cs32x15.seaice_dynmix test exp.)
1591    o verification/tutorial_tracer_adjsens/
1592      - add extra sub-verification which uses "SOM" advection scheme
1593        (2nd Order-Moment Advection Scheme, Prather Limiter) with
1594          #define GAD_ALLOW_TS_SOM_ADV in GAD_OPTIONS.h
1595        and in data:
1596          multiDimAdvection=.TRUE.,
1597          tempAdvScheme=81,
1598          saltAdvScheme=81,
1599    o model/src:
1600      - introduce ALLOW_BALANCE_RELAX which allow the removal
1601       of the global mean of relaxation terms by setting
1602       balanceThetaClimRelax and balanceSaltClimRelax
1603      - disable balanceEmPmR and balanceQnet in the case when useSeaice.
1604       This case is now treated appropriately in seaice_growth.F
1605    o pkg/seaice:
1606      - do balanceEmPmR and balanceQnet based on the net fluxes
1607        (SItflux) that enter the ocean+ice system rather than QNET
1608        and EMPMR. Works best in real fresh water.
1609      - SIatmFW, SIatmQnet, and SItflux computations had to be moved
1610        out of the diagnotics bloc, and stored in global arrays.
1611    
1612    checkpoint63o (2012/06/29)
1613    o vertical mixing schemes:
1614      - remove unused S/R CALC_BUOYANCY (left from branch-atmos merging)
1615      - replace computation of density (in Function STATE1, opps_calc.F) by a call
1616        to S/R FIND_RHO_SCALAR
1617      - pass sigmaR to S/R PP81_CALC, MY82_CALC (but not yet used) and to GGL90_CALC
1618        and use it for N^2 calculation in ggl90_calc.F (save 2 density computations);
1619        affects output (vermix.ggl90) at truncation level.
1620    o testreport:
1621      - change adjustment of SIZE.h for mpi+mth testing: preserve enough tiles
1622        (nSx,nSy) for the number of threads (from eedata.mth)
1623    o model/src:
1624      - remove 2nd set of calls at the top of initialise_varia.F (Adjoint part)
1625        related to Non_Lin Free-Surf or Bottom-Control (but not longer necessary).
1626  o verification/tutorial_tracer_adjsens/  o verification/tutorial_tracer_adjsens/
1627    - compile with ALLOW_CG2D_NSA    - compile with ALLOW_CG2D_NSA
1628    - run with nonlinFreeSurf=3    - run with nonlinFreeSurf=3
