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