4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    o pkg/salt_plume:
7      - salt_plume_frac.F:
8         clean up local param names
9         reformulate (1-frac) to frac; original 1-frac was based on swfrac code
10    o pkg/ecco:
11      - cost_gencost_seaicev4.F:
12         reformulate proxy cost as function of sst and local param SEAICE_freeze
13         change cost names from siv4-[sst,vol] to siv4-[deconc,exconc]
14      - add stop statement if old names siv4-[sst,vol] are used
15      - add snapshots + cost reports for atmospheric longwave
16      - remove factor 0.1 in front of wtau[u,v]
17      - replace never used flag ALLOW_TMI_COST_CONTRIBUTION with
18         ALLOW_TMI_SST_COST_CONTRIBUTION
19    o pkg/smooth:
20      - move param smooth2Ddiffnbt to pkg/ecco
21    o autodiff:
22      - Start to include explicitly AUTODIFF_OPTIONS.h, COST_OPTIONS.h,
23        and CTRL_OPTIONS.h in src files (to enable to skip the ECCO_CPPOPTIONS.h)
24        For now, only in pkgs used in verification/hs94.1x64x5.
25      - Replace ALLOW_AUTODIFF_TAMC by ALLOW_AUTODIFF (except for tape/storage
26        which are specific to TAF/TAMC).
27      - Replace ALLOW_AUTODIFF_OPENAD by ALLOW_OPENAD:
28        since ALLOW_OPENAD is defined in PACKAGES_CONFIG.h (any time pkg/openad
29        is compiled), this simplifies/reduces which *_OPTIONS.h file to include.
30      - OpenAD: change Makefile to generate the appropriate AD_CONFIG.h when
31        building mitgcmuv_ad (make adAll).
32    o pkg/atm_phys:
33      - add some diagnostics for Short-wave and for convection S/R.
34    o pkg/seaice/seaice_growth:
35      - fix a bug in the lateral melt parameterization for SEAICE_ITD
36        in seaice_growth; tempFrz needs to be computed inside the i/j-loop
37      - rearrange loop order for better vector code in the same code block
38      - rewrite the floeDiameter formula to have fewer divisions
39      -  (miraculously) none of this changes the results of seaice_itd
40    o pkg/rw:
41      - add RS version of S/R READ_MFLDS_LEV.
42    o pkg/streamice:
43      - fix the restart test by writing/reading pickup_streamice files.
44    o pkg/seaice:
45      - refine checks for jfnk-related parameters
46      - comment out if statement with SEAICEuseIMEX parameter as long as there
47        is no IMEX code to avoid confusion and surprises
48    
49    checkpoint64u (2014/03/07)
50    o verification/MLAdjust:
51      - rename secondary test suffix:
52         1.leith  -> A4FlxF  + switch to flux-form & add side-drag
53         0.leithD -> AhFlxF  + switch to flux-form
54         0.smag   -> AhVrDv  (use Vorticity-Div. visc form) + add side-drag
55         0.leith  -> AhStTn  (use Strain-Tension visc form) + add side-drag
56    o pkg/mom_vecinv:
57      - remove unused arguments from S/R MOM_VI_HDISSIP & MOM_HDISSIP (as it used
58        to be before mom_calc_visc.F)
59      - skip the call to MOM_CALC_TENSION & MOM_CALC_STRAIN if not needed.
60      - add 2nd copy of vort3 & strain that knows about lateral BC (free/no slip):
61        this is simpler for the adjoint and for diagnostics.
62    o model/src + pkg/momentum:
63      - add input files for  2-D additional Western and Southern cell-edge wall
64         (e.g., to add "thin-wall" where it is =1).
65      - fix sideDrag option for thin-walls with Non-Lin Free-Surf
66        using 2nd hFacZ that is computed from initial (fix domain) hFac
67      - known limitations of thin wall implementation: not yet coded for sigma
68        coords; not working with CD-scheme neither.
69    o pkg/seaice:
70      - rename recently introduced parameters from (wrong name) AB to
71        BDF (backward difference time discretisation)
72      - retire runtime parameters SEAICEuseAB2, SEAICE_abEps
73    o tools/adjoint_options:
74      - remove setting of "OPENAD=true" (now set by command line "genmake2 -oad")
75    
76    checkpoint64t (2014/02/01)
77    o pkg/ecco
78      - add compile flag ALLOW_GENCOST_TIMEVARY_WEIGHT in ECCO_OPTIONS.h and
79        runtime logical flag gencost_timevaryweight to read daily sea-ice sigma
80      - replace hard-coded record number and period which only work for monthly
81        with read-in runtime param that works for other periods (month,day,year)
82    o pkg/thsice
83      - corrected store directive fixes thsice adjoint gradient checks
84    o genmake2 & testreport:
85      - add genmake2 option "-oad" to generate a Makefile for OpenAD built and
86        in this case, use tools/adjoint_options/adjoint_oad as default AD optfile.
87        Update testreport accordingly. No need to set "export OPENAD=true"
88        in adjoint_options/adjoint_oad anymore (will be removed later).
89    o pkg/shelfice:
90      - put T & S shelfice forcing into model surfaceForcing_T,_S (for now,
91        only if SHELFICEboundaryLayer=F); Change model/src/external_forcing.F
92        so that surface forcing applies to k=kSurf if using pkg/shelfice.
93    o pkg/ctrl, pkg/grdchk, pkg/ecco:
94      - Changes to make GENARR more modular (i.e. invisible if not used)
95    o model/src/temp_integrate.F and salt_integrate.F
96      - re-include store directives that were removed on Dec 27th.
97    o model/src/external_forcing_surf.F
98      - add storage directives for EmPmR and PmEpR to avoid recomputation of
99        seaice_model in the adjoint that is problematic when seaice_model is
100        turned off in the adjoint. The resolved issue dated back to July when
101        EXTERNAL_FORCING_SURF call was moved.
102        Update global_ocean.cs32x15/*/output_adm.seaice_dynmix.txt accordingly.
103    o pkg/exf/exf_check.F
104      - fix a small bug again (originally found by Wentao Liu, now found again)
105      - streamline error output
106    o pkg/streamice and aim_v23:
107      - replace a few "_EXCH_XY_RL (" with "_EXCH_XY_RL(", so that
108        Apple's /usr/bin/cpp knows what to do:
109        Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)
110        Target: x86_64-apple-darwin13.0.0
111    
112    checkpoint64s (2014/01/05)
113    o tools/adjoint_options:
114      - switch to fastopt.net TAF server (instead of default fastopt.de) for
115        AD optfiles adjoint_diva & adjoint_f95 (similar to adjoint_default).
116    o model/src:
117      - remove some unnecessary TAF storage directives in forward_step.F and
118        in dynamics.F (note: not always removed by TAF, e.g., double storage
119        of kappaRU,kappaRV in former version of dynamics.F).
120    o model/src & pkg/ptracers:
121      - call directly GAD_IMPLICIT_R & IMPLDIFF + DWNSLP_APPLY from temp_integrate.F
122        salt_integrate.F and ptracers_integrate.F (instead of from thermodynamics.F)
123        and remove ptracers_dwnslp_apply.F & ptracers_implicit.F
124      - call MATRIX_STORE_TENDENCY_EXP for each tracer (in ptracers_integrate.F)
125      - add fZon & fMer as output argument of S/R GAD_CALC_RHS.
126      - update TAF AD-output of experiments global_ocean.90x40x15 (13 for AD-grad).
127    o useSingleCpuInput separates single-CPU input from single-CPU output;
128        for now only implemented for in exf_interp_read.F
129    o verification/advect_xy:
130      - fix missing EXCH call in local version of ini_salt.F and update output.
131    o momentum diagnostics:
132      - fix which deltaT is used in Total-Tendency diagnostics.
133      - fix typo in diagnostics for momentum tendency from AB.
134    o pkg/seaice/seaice_lsr.F: fix an initialisation bug for the
135        SEAICE_VECTORIZE_LSR_ZEBRA option that lead to NaNs on a NEC-SX8
136    
137    checkpoint64r (2013/12/08)
138    o verification/*/results:
139      - Update reference output of experiments that were passing with just 13 digits
140         (make it easier to detect future changes in results)
141    o model/src & pkg/ptracers:
142      - move calls to GAD_ADVECTION (Multi-Dim advection) from thermodynamics.F to
143        inside temp_integrate.F and salt_integrate.F and from ptracers_advection.F
144        to inside ptracers_integrate.F ; remove ptracers_advection.F
145    o coupling interface pkgs:
146        [atm_compon_interf, ocn_compon_interf & atm_ocn_coupler]
147      - change the config check to test the agreement of Ocean Depth
148        with ATM land/sea mask (instead of ATM orography);
149      - send to coupler the number of coupler time-steps to do for this run:
150        this allows to check for consistency and don't need anymore to be
151        specified in parameter file "data";
152      in coupler:
153      - check consistency of RunOff map versus Ocean Depth and ATM land/sea mask.
154      - improve report to log-file of config setting (pass log-file unit to few S/R)
155    o pkg/compon_communic:
156      - add coupling send/receive for non-tiled integer vector;
157      - add S/R to check and stop if any proc has an error (similar to
158        eesupp/src/stop_if_error.F but single thread and across Comm_World).
159    o pkg/exch2:
160      - in exch2*_get_rx[1,2]: use new list "W2_tileIndex" to replace search
161        through list of all tiles my proc owns.
162    o model/src:
163      - AUTODIFF only: in calc_adv_flow.F, recompute rTransKp (instead of copying
164        from rTrans) to simplify dependencies (no need to store rTrans anymore in
165        calling S/R); this affects AD results at machine truncation level:
166        update AD-output (TAF) of experiments: 1D_ocean_ice_column,
167        bottom_ctrl_5x5 & obcs_ctrl (12 digits for AD grad, same FWD grad).
168    o tools/build_options:
169      - simplify Warnings options (-ieee & -devel cases) in linux_amd64_gfortran
170    o coupling interface pkgs:
171        [compon_communic, atm_compon_interf & ocn_compon_interf]
172      - move declaration of local array "ibuf" out of header file "CPLR_SIG.h"
173        to each S/R that needs it; remove un-used variables.
174      - change component tile registration (cpl_register.F in both compon_interf
175        and mitcomponent_tile_register.F) to pass the full list of tiles
176        information (including bi,bj) in 1 vector (instead of in a bi,bj matrix).
177      - with pkg/exch2: adopt the same convention used for I/O to define mapping
178        towards coupler global array (unless W2_useE2ioLayOut=F):
179         a) can now use different tiling between atm & ocn comp.
180         b) no needs to modify the run-Off map when changing tiling (was needed
181            even if using the same tiling between atm & ocn).
182         c) will allow to run with blank-tiles in 1 component (e.g., for ocean
183            full land tiles); not yet tested.
184      - check for valid mapping from comp. tile to coupler global array
185      - improve report of tile registration results to log file.
186    o pkg/exch2:
187      - in eesupp/src/eeboot.F: move call to W2_EEBOOT before Coupler
188        tile-registration (CPL_REGISTER);
189      - activate (un-comment) definition and setting of "W2_tileIndex" list to
190        store the local bi,bj indices of each tile;
191      - also print bi,bj in local report to log file;
192      - fix pkg/debug/debug_cs_corner_uv.F for the case nSy > 1 (left from
193        Jun 2009 modif of pkg/exch2).
194    o testing on baudelaire:
195      - run 2 tests at a time: no significant slow down (since enough cpu) and
196        get the full set of test done earlier
197      - switch the ifort test to "-devel" ; run the OpenAD test everyday.
198    o model/src/thermodynamics.F and routines called from it:
199      - pkg/gmredi: gmredi_residual_flow.F (replacing gmredi_calc_uvflow.F &
200        gmredi_calc_wflow.F) to update eulerian velocity (input) into residual
201        velocity (outp) by adding bolus velocity.
202      - model/src: calc_adv_flow.F (replacing calc_common_factors.F) to compute
203        mass transport from velocity + lateral grid cell area
204      - rename calc_gt.F to temp_integrate.F (includes call to TIMESTEP_TRACER)
205      - rename calc_gs.F to salt_integrate.F (includes call to TIMESTEP_TRACER)
206     in thermodynamics.F
207      - remove k from thermodynamics.F and move it to temp_integrate.F
208        salt_integrate.F and ptracers_integrate.F (now done inside the tracer
209        loop).
210      - compute locally (in thermodynamics.F) 3-D velocity field that is used to
211        advect tracers; pass it as argument to GAD_ADVECTION, GAD_SOM_ADVECT,
212        PTRACERS_ADVECTION, TEMP_INTEGRATE, SALT_INTEGRATE, PTRACERS_INTEGRATE,
213        GAD_IMPLICIT_R and PTRACERS_IMPLICIT
214      - update AD-output (TAF & OAD) of experiments: 1D_ocean_ice_column,
215        global_ocean.90x40x15, tutorial_global_oce_biogeo and
216        tutorial_tracer_adjsens (+ TLM output).
217    o tools/OAD_support and (verification/*/) code_oad:
218      - OAD_support/cb2mGetModules.csh: add PACKAGES_CONFIG.h in header file to
219        module conversion ; remove unneeded CPP_EEOPTIONS.h.
220      - code_oad/CPP_OPTIONS.h: remove PACKAGES_CONFIG.h and use a more standard
221        version (closer to model/inc/CPP_OPTIONS.h).
222    o model/src:
223      - remove parameter "useOldFreezing" from PARAMS.h and push it to the
224        retired list of parameters (routine FREEZE has been replace by surface
225        freezing (10.yrs ago) and by pkg/frazil (interior freezing).
226    o pkg/gmredi:
227      - add option (GM_CALC_TRANSP_FROM_VEL) to compute transport directly from
228        velocity (same scheme but affects machine truncation) for GM_AdvForm.
229      - update output of FWD experiments: front_relax.bvp,
230        global_ocean.90x40x15.dwnslp, global_ocean.cs32x15 and ideal_2D_oce.
231    
232    checkpoint64q (2013/11/17)
233    o verification:
234      - generate new output on baudelaire (gfortran, -ieee) for OpenAD experiments
235        tutorial_global_oce_biogeo and global_ocean.90x40x15.
236      - generate new output (growth & melt) for seaice_itd experiment after
237        updating the input pickup_seaice files (previously wrong).
238    o pkg/cost:
239      - define a "final cost function" for each tile, and use GLOBAL_SUM_TILE_RL
240        (instead of _GLOBAL_SUM_RL) to get the final cost from all procs & threads:
241        o this fixes global-sum value if multi-threads (since GLOBAL_SUM_RL
242          cannot be applied to var in common block).
243        o allows to get results independent of tile-per-proc setting (if using
244          slower GLOBAL_SUM_SEND_RECV option).
245      - update accordingly: seaice_cost_final.F, shelfice_cost_final.F,
246        thsice_cost_final.F and ecco_cost_final.F (this one affects lab_sea
247        forward gradients: update output).
248      - update */code_oad/externalDummies.F by adding dummy GLOBAL_SUM_TILE_RL
249        S/R and, for most exp., also comment out GLOBAL_SUM_R8.
250    o pkg/mom_common:
251      - move to pkg/mom_common and model/src (previously in tutorial_deep_convection
252        code) 2nd version of isotropic 3-D Smagorinsky code interface: strain and
253        viscosity are locally declared in dynmics.F and pass as argument to CALC_GW;
254        ensure that all field value that are used are set.
255    o tutorial_deep_convection (smag3d):
256      - add missing scaling in mom_calc_smag_3d.F;
257      - set smag3D_coeff in input.smag3d such that results do not change.
258    o pkg/dic:
259      - change dic_cost.F to compute cost on each tile first and then apply
260        GLOBAL_SUM_TILE_RL: this affects forward gradient of AD experiments
261        tutorial_dic_adjoffline & tutorial_global_oce_biogeo; update output.
262      - remove kLev argument and use GLOBAL_SUM_TILE_RL in tracer_meanarea.
263    o eesupp/src & pkg/mdsio:
264      - remove gather/scatter_vector.F (from eesupp) and mdsio_read/writevector.F
265        (from pkg/mdsio) since they are no longer used for tape IO.
266      - move simple C subroutine "setdir.c" from pkg/compon_communic to eesupp/src
267        (+ keep a copy in pkg/atm_ocn_coupler).
268    o verification/isomip:
269      - split domain in 8 squared tiles (instead of just 2) for FWD, AD & OAD tests.
270    o tools/build_options:
271      - optfile linux_amd64_ifort11, fast (no ieee) case:
272        to get a working restart for all experiments, add "-fp-model source"
273        to FOPTIM (also remove "-opt-streaming-stores auto" <- this is the default).
274    
275    checkpoint64p (2013/10/20)
276    o pkg/autodiff:
277      - adread_adwrite.F: when type and length do not match ALLOW_AUTODIFF_WHTAPEIO
278        criteria, return to simple (default) tape IO format.
279    o pkg/mdsio (+ eesupp/src):
280      - rewrite/simplify tape-IO S/R (new S/R MDS_READ/WRITE_TAPE replace
281        previous MDSREAD/WRITEVECTOR) with 2 array argument from each type (R4/R8);
282      - fix globalFile and singleCpuIO options using simpler global mapping.
283      - new pairs of scatter/gather vector S/R (one for each type, generated from
284        template) corresponding to simpler global mapping.
285      - adread_write.F: switch to new S/R (but leave old calls commented) and write
286        to globalFile when parameter globalFiles is set to True.
287      - switch on useSingleCpuIO in AD experiments: global_ocean.90x40x15 & isomip.
288    o pkg/autodiff:
289      - adread_adwrite.F: add a hack for RS arrays (when RS=real*4);
290        with ALLOW_AUTODIFF_WHTAPEIO defined, since corresponding (real*4) is
291        missing, just add a STOP if array type do not match.
292    o pkg/exf:
293      - to allow to use seaice-fraction from pkg/exf in other pkgs than pkg/seaice:
294         rename CPP option EXF_ALLOW_SEAICE_RELAX to EXF_SEAICE_FRACTION
295         and rename array obsSIce to exf_iceFraction.
296    o tutorial_deep_convection:
297      - add 1rst version of isotropic 3-D Smagorinsky code (from Louis-Philippe),
298        for now all in this exp. code dir.
299      - add secondary test using Smag-3D viscosity (keep very low backgroud visc for
300        testing) and flux-limter advection scheme for Temp. (no explicit diffusion).
301    o eesupp/src:
302      - added SINGLE_DISK_IO option because reading of parameter files on
303        very large number of processors did not work with existing set-up
304    
305    checkpoint64o (2013/09/25)
306    o pkg/atm_phys & atm_compon_interf:
307      - allows for coupling of gray-atmosphere (atm_phys) with ocean.
308    o tools/build_options:
309      - switch from "-fPIC" to "-mcmodel=medium" in optfiles: linux_amd64_gfortran
310        & linux_amd64_ifort11 and in linux_amd64_g77 & linux_amd64_open64 also
311        remove CPP setting (was identical to genmake2 default).
312    o pkg/gmredi & model/src: Some updating and work done on the residual model.
313      - created new file model/src/calc_eddy_stress.F to calculate the eddy stress.
314      - fixed up the calculation of the eddy stress and how it is added to the
315        external forcing via taueddy_external_forcing.F
316      - at the moment, it is very experimental and only works with the variable eddy
317        diffusivity calculated in gmredi_k3d.F
318    o pkg/seaice/seaice_check.F: add a check to catch the case of specifying
319        lw/swfluxfile instead of lw/swdownfile in data.exf together with pkg/seaice
320    o testreport (& tools/do_tst_2+2):
321      - for MPI test, set default COMMAND to 'mpirun -v -np TR_NPROC ./{executable}'
322    o tools/build_options: linux_amd64_gfortran & linux_amd64_ifort11:
323      - remove CPP='cpp -traditional -P' (this is genmake2 default)
324      - add switch (for big setups) to use 'medium' memory-model (but leave it
325        commented out for now). Note: needed with FC 19 to compile big setups.
326    o pkg/atm_compon_interf:
327      - regroup per field origin (model & pkgs) the coupling storage routines
328         (which accumalate in time each coupling field)
329      - move bi,bj loops inside atm_store_my_data.F and store also wind-stress;
330        update accordingly + simplify aim_do_physics.F
331    
332    checkpoint64n (2013/08/26)
333    o pkg/bbl:
334      - update formulation to reduce dispersion of tracer properties in bbl
335      - replaced horizontal and vertical transport parameters with velocities
336      - changes results for verification/global_with_exf.yearly
337    o verification/halfpipe_streamice:
338      - change to matrix construction; update both Fwd & AD output.
339    o verification/tutorial_tracer_adjsens:
340      - OpenAD test: switch to vector-invariant momentum since fluxform with
341        rStar causes problems with OpenAD; update output.
342    o tools:
343      - genmake2: define a common prefix for all temp-file names ; move them
344        to local /tmp disk (but would be easy to move them back);
345      - xmakedepend: apply the same switch for temp-files.
346    o pkg/offline:
347      - changes for use with rStar (NLFS): assume that we continue to provide
348        UVELMASS/hFacW_ini & VVELMASS/hFacS_ini (hFacWi,S_ini as written in grid
349        output files) and apply r* scaling at each time-step (function of the time
350        varying Eta field); use normal pickup files (needed for restart with NLFS).
351    o adjoint with OpenAD:
352      - move OpenAD-specific files from verification/OpenAD/code_oad_all to a new
353        package openad.  This package has to be compiled for all runs with OpenAD
354        instead of specifying code_oad_all as a modification directory.
355      - link the fortran templates from tools/OAD_support to the build directory
356        for preprocessing to avoid conflicts between different setups compiled
357        simultaneously and simplify cleanup.
358    o pkg/exf:
359      - in exf_getforcing.F: comment out most of the EXCH calls (fields used by
360        main model or other pkgs are exchanged in EXF_MAPFIELDS).
361    o model/src:
362      - do_stagger_fields_exchanges.F: skip EXCH calls when using pkg/offline
363        (similar to do_fields_blocking_exchanges.F).
364    o tools/genmake2:
365      - remove TAF output src code just before calling staf (when not doing a fresh
366        built, will stop if things go wrong with staf).
367      - fix target "adobj" (left from TAF version-2 transition)
368    o pkg/diagnostics:
369      - add a parameter to track the status of pkg/diagnostics activation;
370        this replace/extend the use of logical param "settingDiags" (to check
371        when adding diag to the list) to also check any DIAGNOSTICS_[]FILL* call.
372        New S/R to print error message and stop when pkgStatus is not right.
373      - to try: add a warning when "data.diagnostics" exist but useDiagnostics=F.
374    
375    checkpoint64m (2013/08/13)
376    o model/inc:
377      - move FCORI_MACROS.h from PARAMS(_MACROS).h to GRID_MACROS.h (left from
378        8 yrs ago modif when Coriolis arrays were moved from PARAMS.h to GRID.h)
379    o pkg/kpp & aim_v23:
380      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
381    o pkg/seaice:
382      - restore (last time on 2011/12/24) ability to compile pkg/seaice with
383        undefined pkg/exf ALLOW_ATM_TEMP or ALLOW_RUNOFF CPP-options.
384      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
385    o eesupp/src:
386      - fix check for overlap-size argument (myOLn.GT.MAX_OLY_EXCH)
387        in exch1_rx[_ad].template (thanks to Francois Lefeuvre report).
388    o switch to TAF version-2:
389      - add flow directives to "freeze" naming convention for ad-routines that
390        are used in I/O routines of adjoint state and associated common blocks
391        that are used in adcommon.h (backward compatible with version-1)
392      - update all ad-optfiles (in tools/adjoint_options + few local to some
393        verification exp) to switch to latest TAF version (currently 2.5.5);
394        merge "*_mpi" adoptfiles into the corresponding non-mpi (but commented
395        out except for diva).
396      - the major change with TAF version-2 is that both the differentiated
397        routines and the forward routines (new) are returned as part of the TAF
398        output source code. Update genmake2 accordingly.
399      - new output for AD experiment tutorial_global_oce_biogeo (better AD gradient
400        with version-2 when compared to TLM or FWD gradient); other experiments
401        output show minor changes (machine truncation level); update the few AD &
402        TLM output with 12 matching digits only (some prior to version-2 switch).
403    
404    checkpoint64l (2013/08/05)
405    o model/src:
406      - in dynamics.F, skip the call to CALC_VISCOSITY if momViscosity=F
407      - main_do_loop.F: no longer includes additional (AUTODIFF) header files
408        when using TAF but only if using OpenAD.
409    o pkg/mom_common+fluxform+vecinv:
410      - always set horiz. viscosity arrays to background value before calling
411        MOM_CALC_VISC (in MOM_FLUXFORM & MOM_VECINV) and call S/R MOM_CALC_VISC
412        only when using variable horiz. viscosity (useVariableVisc=T);
413      - simplify mom_vecinv.F (only 1 block for momViscosity).
414    o pkg/mom_common: variable horiz. viscosity in NH code
415      - move horiz-viscosity 3-D arrays viscAh_W & viscA4_W (used in calc_gw.F)
416        from model/inc/NH_VARS.h to pkg/mom_common/MOM_VISC.h
417      - store in common block (in MOM_VISC.h) logical parameters: useHarmonicVisc,
418        useBiharmonicVisc & useVariableVisc.
419      - fix old bug (already in 1rst implementation of variable horizontal viscosity
420        in calc_gw.F, version 1.27, 2006/06/20):
421        horizontal bi-harmonic viscosity in gW was missing when wiscA4W=0
422        even if variable bi-harmonic viscosity (e.g., viscA4Grid) was non-zero.
423      - change background horiz viscosity in vertical momentum (gW) to always be
424        viscAhW,viscA4W (instead of switching to viscAhD, viscA4D when using
425        any type of variable viscosity, e.g., viscAh/4Grid)
426      - change default value of viscAhW,viscA4W to viscAhD,viscA4D (instead of
427        viscAh,viscA4) which default to viscAh,viscA4 :  this avoid missing
428        horiz. viscosity in W eq when just setting viscAhD/Z,viscA4D/Z (since
429        default viscAh,viscA4 is zero).
430    o model/src:
431      - extend length of drC & recip_drC from Nr to Nr+1.
432    o Divided Adjoint (DIVA) with MPI:
433      - genmake2: do not create local ./mpi_headers dir when no file to copy into.
434      - remove option ALLOW_DIVIDED_ADJOINT_MPI (replaced by ALLOW_DIVIDED_ADJOINT
435        and ALLOW_USE_MPI) from model/src code and from ECCO_CPPOPTIONS.h.
436    
437    checkpoint64k (2013/07/23)
438    o tools/OAD_support:
439      - avoid the need for file "oadtempflile" in insertTemplateDir.bash
440        and remove it from genmake2.
441    o tools/build_options:
442      - remove MPI_HEADER_FILES_INC setting (no longer used) and comment out
443        MPI_HEADER_FILES list (let genmake2 find the missing headers)
444    o verification/halfpipe_streamice:
445      - change to driving stress formulation; update both Fwd & AD output.
446    o tools/genmake2 and Divided Adjoint with MPI:
447      - remove default setting of MPIINCLUDEDIR from $MPIHOME (always been broken);
448      - only create local ./mpi_headers dir if using MPI and MPIINCLUDEDIR is set;
449      - add new variable (LOCAL_MPI_HEADERS, replace MPI_HEADER_FILES_INC) in
450        Makefile, which is set by genmake2, and check which mpi-headers are needed.
451        Note: need to update adjoint_options/adjoint_diva_mpi accordingly.
452      - update target "CLEAN" (to also remove ./mpi_headers/ dir).
453    o testreport:
454      - changes for Divided Adjoint Run: when file "run_ADM_DIVA" is present,
455        perform additional runs (number of additional runs is "add_DIVA_runs" taken
456        from file run_ADM_DIVA ; should match "nchklev_3" in file "code_ad/tamc.h").
457    o verification/lab_sea (AD test):
458      - change to test Divided Adjoint Run in this set-up (both standard AD test
459        and 2 secondary AD test: noseaice + noseaicedyn); drop the evp AD test.
460    o pkg atm_ & ocn_compon_interf:
461      - remove cpl_earlyExpImpCall=F option (was mainly a hack added for the old
462        staggerTimeStep implementation) and disable (retired) corresponding
463        parameter.
464    o pkg/offline:
465      - comment out unused field-array: ICEM, ConvectCount, hflx[01], icem[01];
466      - add S/R OFFLINE_CHECK to print offline parameter summary
467        and stop if loading a file that is not used;
468      - enable to calculate GMRedi tensor, KPP mixing and convective index
469        when the corresponding file(s) is/are not specified (but pkg is used).
470      - comment out resetting of monitorFreq (to endTime) since it still useful
471        for monitoring CFL numbers and checking offline fields.
472    o OpenAD:
473      - do not define OAD_DEBUG (in tools/adjoint_options/adjoint_oad) to get
474        smaller standard output) and generate new (smaller) output (on baudelaire
475        using gfortran with -ieee) for exp. tutorial_tracer_adjsens
476    o model/src:
477      - call EXTERNAL_FORCING_SURF outside bi,bj loops (in do_oceanic_phys.F),
478        (where external_forcing_adjust was called) and change list of arguments;
479      - merge external_forcing_adjust.F into external_forcing_surf.F
480      - put surface relaxation of SST & SSS in new S/R (forcing_surf_relax.F)
481        which also contains balancing surface relaxation (ALLOW_BALANCE_RELAX,
482        previously in file "balance_relax.F", now removed); remove corresponding
483        arrays in FFIELDS.h.
484      - EXTERNAL_FORCING_SURF is now called when using pkg/offline; implement
485        a hack for getting back surfaceForcingS (loaded from file) when using
486        ALLOW_OLD_VIRTUALFLUX (pkg/dic, in DIC_OPTIONS.h) in offline set-up.
487      - update output of AD test experiment global_ocean.cs32x15.seaice_dynmix
488        (was getting only 11 digits for AD-grad, due to different truncation
489         error in AD code).
490    
491    checkpoint64j (2013/07/04)
492    o pkg/offline:
493      - to enable the use of other features with pkg offline (e.g., obcs),
494        also call S/R DO_OCEANIC_PHYS in offline run - more modifs to come.
495      - comment out "allowFreezing" (now active) in 2 offline testing exp.
496    o pkg/exf ALLOW_RUNOFTEMP
497      - fix sign and make compatible with temp_EvPrRn .NE. UNSET_RL
498      - ahdded RUNOFTEMP test to verification/global_ocean.cs32x15/input.seaice
499      - changes verification/global_ocean.cs32x15/results/output.seaice.txt
500    o pkg/atm_phys:
501      - allows to add some damping on uVel,vVel (strength only function of k).
502    o verification, ad-tests:
503      - reduce length of the simulation for AD test: global_ocean.cs32x15.seaice,
504        global_ocean_ebm and offline_exf_seaice.thsice.
505    o verification/halfpipe_streamice:
506      - found a bug in s/r pkg/streamice/streamice_advect_thickness which caused
507        flux input boundary conditions to be ignored; a fix for this bug changed
508        verification results for forward test.
509      - add adjoint test.
510    o pkg/ptracers:
511      - allow to restart without SOM pickup (resetting SOM to zero).
512    o pkg/gmredi:
513      - New parameterisation for the calculation of K and (GM_PsiX,GM_PsiY) added.
514      - It uses mixing length theory and suppression by steering level effects to
515        calculate a diffusivity used in the Redi tensor (see Bates et al., submitted
516        to JPO, for more details).
517      - It also uses the diffusivity to calculate an eddy induced streamfunction
518        based on a PV closure (rather than a buoyancy closure as in GM).
519      - New files added to pkg/gmredi:
520        gmredi_k3d.F calculates the diffusivity for the Redi tensor and the eddy
521          induced overturning streamfunction (called from gmredi_calc_tensor)
522        gmredi_calc_eigs.F calculates the eigenvalues and eigenvectors required
523          for use in gmredi_k3d
524        gmredi_calc_urms.F calculates the the rms eddy velocity used to calculate
525          the eddy diffusivity
