4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/seaice: fix restart problem for ITD with new ice strength parameterisation:
8      - move computation of opnWtrFrac = 1-AREA to before computing ice strength
9      - this changes the results (but not for any verification experiment, because none tests
10        this), but avoids having an extra field in the restart files
11    o pkg/seaice: remove global variable TICE (not needed)
12      - replace by TICES or local variable where necessary (cost_seaice_test,
13        seaice_diagnostics_state)
14      - move copying TICE to TICES from seaice_check_pickup to seaice_read_pickup
15      - use specific read/write routines for reading and writing individual leves
16        of a multilevel field
17    o pkg/ctrl & model/inc:
18      - move additional anomaly fields of control vars (related to options:
19         ALLOW_KAPGM_CONTROL, ALLOW_KAPREDI_CONTROL and ALLOW_BOTTOMDRAG_CONTROL)
20        from DYNVARS.h into new header file: CTRL_FIELDS.h
21    o pkg/seaice: some small modifications to the ridging code
22      - make fw2ObyRidge a global variable and add the freshwater flux to
23        seaice_growth
24      - pass actual thickness from seaice_prepare_ridging, so that it is
25        computed only in one place and compute it in the same way as in
26        seaice_growth
27      - initialise more fields in seaice_do_ridging that where cause floating
28        point exceptions over land
29    o pkg/seaice: preparations for ridging code and first real ridging code
30      - move most of "PART 1" of S/R seaice_growth into a new and separate
31        S/R seaice_reg_ridge that will both regularize the state variable after
32        advection call the actual ridging routine;
33      - requires to make 5 fields global fields: d_HEFFbyNEG,d_HSNWbyNEG,
34        d_AREAbyRLX,d_HEFFbyRLX,saltFluxAdjust;
35      - remove ridging code from seaice_advdiff
36      - clean up remaining part 1 of seaice_growth in an attempt to make it
37        more readable (this is probably subjective)
38      - call seaice_itd_redist once in the initialisation phase to have the initial
39        conditions in the correct category
40      - finally: add new ridging routine for ITD code
41    
42    checkpoint64v (2014/04/11)
43    o pkg/ecco:
44      - add runtime parameters mdt[start,end]date[1,2]
45      - rename variable "tpmean" as "mdt" and "topexmeanfile" as "mdtdatfile"
46    o pkg/seaice:
47      - make deltaC a global variable, so that it can be used in ridging code
48      - first step towards ridging: introduce new routines that compute
49        ice strength based on ridging parameters
50      - add diagnostic for HSNOWITD
51      - add opnWtrFrac as a global variable (required for ridging scheme)
52    o pkg/salt_plume + pkg/seaice/seaice_growth.F
53      - add SALT_PLUME_IN_LEADS flag to activate pkg/salt_plume only when ice
54        AREA exceeds a threshold (code contributed by I.Fenty in 2011)
55    o verification/hs94.1x64x5:
56      - leave ALLOW_AUTODIFF_TAMC undefined in code_oad/AUTODIFF_OPTIONS.h
57      - do not use ECCO_CPPOPTIONS.h anymore for TAF & OpenAD Adjoint tests.
58    o autodiff:
59      - Start to include explicitly AUTODIFF_OPTIONS.h, COST_OPTIONS.h,
60        and CTRL_OPTIONS.h in src files (to enable to skip the ECCO_CPPOPTIONS.h)
61        For now, only in pkgs used in verification/hs94.1x64x5.
62      - Replace ALLOW_AUTODIFF_TAMC by ALLOW_AUTODIFF (except for tape/storage
63        which are specific to TAF/TAMC).
64      - Replace ALLOW_AUTODIFF_OPENAD by ALLOW_OPENAD:
65        since ALLOW_OPENAD is defined in PACKAGES_CONFIG.h (any time pkg/openad
66        is compiled), this simplifies/reduces which *_OPTIONS.h file to include.
67      - OpenAD: change Makefile to generate the appropriate AD_CONFIG.h when
68        building mitgcmuv_ad (make adAll).
69    o pkg/ecco:
70      - cost_gencost_seaicev4.F:
71         reformulate proxy cost as function of sst and local param SEAICE_freeze
72         change cost names from siv4-[sst,vol] to siv4-[deconc,exconc]
73      - add stop statement if old names siv4-[sst,vol] are used
74      - add snapshots + cost reports for atmospheric longwave
75      - remove factor 0.1 in front of wtau[u,v]
76      - replace never used flag ALLOW_TMI_COST_CONTRIBUTION with
77         ALLOW_TMI_SST_COST_CONTRIBUTION
78    o pkg/atm_phys:
79      - add some diagnostics for Short-wave and for convection S/R.
80    o pkg/seaice/seaice_growth:
81      - fix a bug in the lateral melt parameterization for SEAICE_ITD
82        in seaice_growth; tempFrz needs to be computed inside the i/j-loop
83      - rearrange loop order for better vector code in the same code block
84      - rewrite the floeDiameter formula to have fewer divisions
85      -  (miraculously) none of this changes the results of seaice_itd
86    o pkg/smooth:
87      - move param smooth2Ddiffnbt to pkg/ecco
88    o pkg/salt_plume:
89      - salt_plume_frac.F:
90         clean up local param names
91         reformulate (1-frac) to frac; original 1-frac was based on swfrac code
92    o pkg/rw:
93      - add RS version of S/R READ_MFLDS_LEV.
94    o pkg/streamice:
95      - fix the restart test by writing/reading pickup_streamice files.
96    o pkg/seaice:
97      - refine checks for jfnk-related parameters
98      - comment out if statement with SEAICEuseIMEX parameter as long as there
99        is no IMEX code to avoid confusion and surprises
100    
101    checkpoint64u (2014/03/07)
102    o verification/MLAdjust:
103      - rename secondary test suffix:
104         1.leith  -> A4FlxF  + switch to flux-form & add side-drag
105         0.leithD -> AhFlxF  + switch to flux-form
106         0.smag   -> AhVrDv  (use Vorticity-Div. visc form) + add side-drag
107         0.leith  -> AhStTn  (use Strain-Tension visc form) + add side-drag
108    o pkg/mom_vecinv:
109      - remove unused arguments from S/R MOM_VI_HDISSIP & MOM_HDISSIP (as it used
110        to be before mom_calc_visc.F)
111      - skip the call to MOM_CALC_TENSION & MOM_CALC_STRAIN if not needed.
112      - add 2nd copy of vort3 & strain that knows about lateral BC (free/no slip):
113        this is simpler for the adjoint and for diagnostics.
114    o model/src + pkg/momentum:
115      - add input files for  2-D additional Western and Southern cell-edge wall
116         (e.g., to add "thin-wall" where it is =1).
117      - fix sideDrag option for thin-walls with Non-Lin Free-Surf
118        using 2nd hFacZ that is computed from initial (fix domain) hFac
119      - known limitations of thin wall implementation: not yet coded for sigma
120        coords; not working with CD-scheme neither.
121    o pkg/seaice:
122      - rename recently introduced parameters from (wrong name) AB to
123        BDF (backward difference time discretisation)
124      - retire runtime parameters SEAICEuseAB2, SEAICE_abEps
125    o tools/adjoint_options:
126      - remove setting of "OPENAD=true" (now set by command line "genmake2 -oad")
127    
128    checkpoint64t (2014/02/01)
129    o pkg/ecco
130      - add compile flag ALLOW_GENCOST_TIMEVARY_WEIGHT in ECCO_OPTIONS.h and
131        runtime logical flag gencost_timevaryweight to read daily sea-ice sigma
132      - replace hard-coded record number and period which only work for monthly
133        with read-in runtime param that works for other periods (month,day,year)
134    o pkg/thsice
135      - corrected store directive fixes thsice adjoint gradient checks
136    o genmake2 & testreport:
137      - add genmake2 option "-oad" to generate a Makefile for OpenAD built and
138        in this case, use tools/adjoint_options/adjoint_oad as default AD optfile.
139        Update testreport accordingly. No need to set "export OPENAD=true"
140        in adjoint_options/adjoint_oad anymore (will be removed later).
141    o pkg/shelfice:
142      - put T & S shelfice forcing into model surfaceForcing_T,_S (for now,
143        only if SHELFICEboundaryLayer=F); Change model/src/external_forcing.F
144        so that surface forcing applies to k=kSurf if using pkg/shelfice.
145    o pkg/ctrl, pkg/grdchk, pkg/ecco:
146      - Changes to make GENARR more modular (i.e. invisible if not used)
147    o model/src/temp_integrate.F and salt_integrate.F
148      - re-include store directives that were removed on Dec 27th.
149    o model/src/external_forcing_surf.F
150      - add storage directives for EmPmR and PmEpR to avoid recomputation of
151        seaice_model in the adjoint that is problematic when seaice_model is
152        turned off in the adjoint. The resolved issue dated back to July when
153        EXTERNAL_FORCING_SURF call was moved.
154        Update global_ocean.cs32x15/*/output_adm.seaice_dynmix.txt accordingly.
155    o pkg/exf/exf_check.F
156      - fix a small bug again (originally found by Wentao Liu, now found again)
157      - streamline error output
158    o pkg/streamice and aim_v23:
159      - replace a few "_EXCH_XY_RL (" with "_EXCH_XY_RL(", so that
160        Apple's /usr/bin/cpp knows what to do:
161        Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)
162        Target: x86_64-apple-darwin13.0.0
163    
164    checkpoint64s (2014/01/05)
165    o tools/adjoint_options:
166      - switch to fastopt.net TAF server (instead of default fastopt.de) for
167        AD optfiles adjoint_diva & adjoint_f95 (similar to adjoint_default).
168    o model/src:
169      - remove some unnecessary TAF storage directives in forward_step.F and
170        in dynamics.F (note: not always removed by TAF, e.g., double storage
171        of kappaRU,kappaRV in former version of dynamics.F).
172    o model/src & pkg/ptracers:
173      - call directly GAD_IMPLICIT_R & IMPLDIFF + DWNSLP_APPLY from temp_integrate.F
174        salt_integrate.F and ptracers_integrate.F (instead of from thermodynamics.F)
175        and remove ptracers_dwnslp_apply.F & ptracers_implicit.F
176      - call MATRIX_STORE_TENDENCY_EXP for each tracer (in ptracers_integrate.F)
177      - add fZon & fMer as output argument of S/R GAD_CALC_RHS.
178      - update TAF AD-output of experiments global_ocean.90x40x15 (13 for AD-grad).
179    o useSingleCpuInput separates single-CPU input from single-CPU output;
180        for now only implemented for in exf_interp_read.F
181    o verification/advect_xy:
182      - fix missing EXCH call in local version of ini_salt.F and update output.
183    o momentum diagnostics:
184      - fix which deltaT is used in Total-Tendency diagnostics.
185      - fix typo in diagnostics for momentum tendency from AB.
186    o pkg/seaice/seaice_lsr.F: fix an initialisation bug for the
187        SEAICE_VECTORIZE_LSR_ZEBRA option that lead to NaNs on a NEC-SX8
188    
189    checkpoint64r (2013/12/08)
190    o verification/*/results:
191      - Update reference output of experiments that were passing with just 13 digits
192         (make it easier to detect future changes in results)
193    o model/src & pkg/ptracers:
194      - move calls to GAD_ADVECTION (Multi-Dim advection) from thermodynamics.F to
195        inside temp_integrate.F and salt_integrate.F and from ptracers_advection.F
196        to inside ptracers_integrate.F ; remove ptracers_advection.F
197    o coupling interface pkgs:
198        [atm_compon_interf, ocn_compon_interf & atm_ocn_coupler]
199      - change the config check to test the agreement of Ocean Depth
200        with ATM land/sea mask (instead of ATM orography);
201      - send to coupler the number of coupler time-steps to do for this run:
202        this allows to check for consistency and don't need anymore to be
203        specified in parameter file "data";
204      in coupler:
205      - check consistency of RunOff map versus Ocean Depth and ATM land/sea mask.
206      - improve report to log-file of config setting (pass log-file unit to few S/R)
207    o pkg/compon_communic:
208      - add coupling send/receive for non-tiled integer vector;
209      - add S/R to check and stop if any proc has an error (similar to
210        eesupp/src/stop_if_error.F but single thread and across Comm_World).
211    o pkg/exch2:
212      - in exch2*_get_rx[1,2]: use new list "W2_tileIndex" to replace search
213        through list of all tiles my proc owns.
214    o model/src:
215      - AUTODIFF only: in calc_adv_flow.F, recompute rTransKp (instead of copying
216        from rTrans) to simplify dependencies (no need to store rTrans anymore in
217        calling S/R); this affects AD results at machine truncation level:
218        update AD-output (TAF) of experiments: 1D_ocean_ice_column,
219        bottom_ctrl_5x5 & obcs_ctrl (12 digits for AD grad, same FWD grad).
220    o tools/build_options:
221      - simplify Warnings options (-ieee & -devel cases) in linux_amd64_gfortran
222    o coupling interface pkgs:
223        [compon_communic, atm_compon_interf & ocn_compon_interf]
224      - move declaration of local array "ibuf" out of header file "CPLR_SIG.h"
225        to each S/R that needs it; remove un-used variables.
226      - change component tile registration (cpl_register.F in both compon_interf
227        and mitcomponent_tile_register.F) to pass the full list of tiles
228        information (including bi,bj) in 1 vector (instead of in a bi,bj matrix).
229      - with pkg/exch2: adopt the same convention used for I/O to define mapping
230        towards coupler global array (unless W2_useE2ioLayOut=F):
231         a) can now use different tiling between atm & ocn comp.
232         b) no needs to modify the run-Off map when changing tiling (was needed
233            even if using the same tiling between atm & ocn).
234         c) will allow to run with blank-tiles in 1 component (e.g., for ocean
235            full land tiles); not yet tested.
236      - check for valid mapping from comp. tile to coupler global array
237      - improve report of tile registration results to log file.
238    o pkg/exch2:
239      - in eesupp/src/eeboot.F: move call to W2_EEBOOT before Coupler
240        tile-registration (CPL_REGISTER);
241      - activate (un-comment) definition and setting of "W2_tileIndex" list to
242        store the local bi,bj indices of each tile;
243      - also print bi,bj in local report to log file;
244      - fix pkg/debug/debug_cs_corner_uv.F for the case nSy > 1 (left from
245        Jun 2009 modif of pkg/exch2).
246    o testing on baudelaire:
247      - run 2 tests at a time: no significant slow down (since enough cpu) and
248        get the full set of test done earlier
249      - switch the ifort test to "-devel" ; run the OpenAD test everyday.
250    o model/src/thermodynamics.F and routines called from it:
251      - pkg/gmredi: gmredi_residual_flow.F (replacing gmredi_calc_uvflow.F &
252        gmredi_calc_wflow.F) to update eulerian velocity (input) into residual
253        velocity (outp) by adding bolus velocity.
254      - model/src: calc_adv_flow.F (replacing calc_common_factors.F) to compute
255        mass transport from velocity + lateral grid cell area
256      - rename calc_gt.F to temp_integrate.F (includes call to TIMESTEP_TRACER)
257      - rename calc_gs.F to salt_integrate.F (includes call to TIMESTEP_TRACER)
258     in thermodynamics.F
259      - remove k from thermodynamics.F and move it to temp_integrate.F
260        salt_integrate.F and ptracers_integrate.F (now done inside the tracer
261        loop).
262      - compute locally (in thermodynamics.F) 3-D velocity field that is used to
263        advect tracers; pass it as argument to GAD_ADVECTION, GAD_SOM_ADVECT,
264        PTRACERS_ADVECTION, TEMP_INTEGRATE, SALT_INTEGRATE, PTRACERS_INTEGRATE,
265        GAD_IMPLICIT_R and PTRACERS_IMPLICIT
266      - update AD-output (TAF & OAD) of experiments: 1D_ocean_ice_column,
267        global_ocean.90x40x15, tutorial_global_oce_biogeo and
268        tutorial_tracer_adjsens (+ TLM output).
269    o tools/OAD_support and (verification/*/) code_oad:
270      - OAD_support/cb2mGetModules.csh: add PACKAGES_CONFIG.h in header file to
271        module conversion ; remove unneeded CPP_EEOPTIONS.h.
272      - code_oad/CPP_OPTIONS.h: remove PACKAGES_CONFIG.h and use a more standard
273        version (closer to model/inc/CPP_OPTIONS.h).
274    o model/src:
275      - remove parameter "useOldFreezing" from PARAMS.h and push it to the
276        retired list of parameters (routine FREEZE has been replace by surface
277        freezing (10.yrs ago) and by pkg/frazil (interior freezing).
278    o pkg/gmredi:
279      - add option (GM_CALC_TRANSP_FROM_VEL) to compute transport directly from
280        velocity (same scheme but affects machine truncation) for GM_AdvForm.
281      - update output of FWD experiments: front_relax.bvp,
282        global_ocean.90x40x15.dwnslp, global_ocean.cs32x15 and ideal_2D_oce.
283    
284    checkpoint64q (2013/11/17)
285    o verification:
286      - generate new output on baudelaire (gfortran, -ieee) for OpenAD experiments
287        tutorial_global_oce_biogeo and global_ocean.90x40x15.
288      - generate new output (growth & melt) for seaice_itd experiment after
289        updating the input pickup_seaice files (previously wrong).
290    o pkg/cost:
291      - define a "final cost function" for each tile, and use GLOBAL_SUM_TILE_RL
292        (instead of _GLOBAL_SUM_RL) to get the final cost from all procs & threads:
293        o this fixes global-sum value if multi-threads (since GLOBAL_SUM_RL
294          cannot be applied to var in common block).
295        o allows to get results independent of tile-per-proc setting (if using
296          slower GLOBAL_SUM_SEND_RECV option).
297      - update accordingly: seaice_cost_final.F, shelfice_cost_final.F,
298        thsice_cost_final.F and ecco_cost_final.F (this one affects lab_sea
299        forward gradients: update output).
300      - update */code_oad/externalDummies.F by adding dummy GLOBAL_SUM_TILE_RL
301        S/R and, for most exp., also comment out GLOBAL_SUM_R8.
302    o pkg/mom_common:
303      - move to pkg/mom_common and model/src (previously in tutorial_deep_convection
304        code) 2nd version of isotropic 3-D Smagorinsky code interface: strain and
305        viscosity are locally declared in dynmics.F and pass as argument to CALC_GW;
306        ensure that all field value that are used are set.
307    o tutorial_deep_convection (smag3d):
308      - add missing scaling in mom_calc_smag_3d.F;
309      - set smag3D_coeff in input.smag3d such that results do not change.
310    o pkg/dic:
311      - change dic_cost.F to compute cost on each tile first and then apply
312        GLOBAL_SUM_TILE_RL: this affects forward gradient of AD experiments
313        tutorial_dic_adjoffline & tutorial_global_oce_biogeo; update output.
314      - remove kLev argument and use GLOBAL_SUM_TILE_RL in tracer_meanarea.
315    o eesupp/src & pkg/mdsio:
316      - remove gather/scatter_vector.F (from eesupp) and mdsio_read/writevector.F
317        (from pkg/mdsio) since they are no longer used for tape IO.
318      - move simple C subroutine "setdir.c" from pkg/compon_communic to eesupp/src
319        (+ keep a copy in pkg/atm_ocn_coupler).
320    o verification/isomip:
321      - split domain in 8 squared tiles (instead of just 2) for FWD, AD & OAD tests.
322    o tools/build_options:
323      - optfile linux_amd64_ifort11, fast (no ieee) case:
324        to get a working restart for all experiments, add "-fp-model source"
325        to FOPTIM (also remove "-opt-streaming-stores auto" <- this is the default).
326    
327    checkpoint64p (2013/10/20)
328    o pkg/autodiff:
329      - adread_adwrite.F: when type and length do not match ALLOW_AUTODIFF_WHTAPEIO
330        criteria, return to simple (default) tape IO format.
331    o pkg/mdsio (+ eesupp/src):
332      - rewrite/simplify tape-IO S/R (new S/R MDS_READ/WRITE_TAPE replace
333        previous MDSREAD/WRITEVECTOR) with 2 array argument from each type (R4/R8);
334      - fix globalFile and singleCpuIO options using simpler global mapping.
335      - new pairs of scatter/gather vector S/R (one for each type, generated from
336        template) corresponding to simpler global mapping.
337      - adread_write.F: switch to new S/R (but leave old calls commented) and write
338        to globalFile when parameter globalFiles is set to True.
339      - switch on useSingleCpuIO in AD experiments: global_ocean.90x40x15 & isomip.
340    o pkg/autodiff:
341      - adread_adwrite.F: add a hack for RS arrays (when RS=real*4);
342        with ALLOW_AUTODIFF_WHTAPEIO defined, since corresponding (real*4) is
343        missing, just add a STOP if array type do not match.
344    o pkg/exf:
345      - to allow to use seaice-fraction from pkg/exf in other pkgs than pkg/seaice:
346         rename CPP option EXF_ALLOW_SEAICE_RELAX to EXF_SEAICE_FRACTION
347         and rename array obsSIce to exf_iceFraction.
348    o tutorial_deep_convection:
349      - add 1rst version of isotropic 3-D Smagorinsky code (from Louis-Philippe),
350        for now all in this exp. code dir.
351      - add secondary test using Smag-3D viscosity (keep very low backgroud visc for
352        testing) and flux-limter advection scheme for Temp. (no explicit diffusion).
353    o eesupp/src:
354      - added SINGLE_DISK_IO option because reading of parameter files on
355        very large number of processors did not work with existing set-up
356    
357    checkpoint64o (2013/09/25)
358    o pkg/atm_phys & atm_compon_interf:
359      - allows for coupling of gray-atmosphere (atm_phys) with ocean.
360    o tools/build_options:
361      - switch from "-fPIC" to "-mcmodel=medium" in optfiles: linux_amd64_gfortran
362        & linux_amd64_ifort11 and in linux_amd64_g77 & linux_amd64_open64 also
363        remove CPP setting (was identical to genmake2 default).
364    o pkg/gmredi & model/src: Some updating and work done on the residual model.
365      - created new file model/src/calc_eddy_stress.F to calculate the eddy stress.
366      - fixed up the calculation of the eddy stress and how it is added to the
367        external forcing via taueddy_external_forcing.F
368      - at the moment, it is very experimental and only works with the variable eddy
369        diffusivity calculated in gmredi_k3d.F
370    o pkg/seaice/seaice_check.F: add a check to catch the case of specifying
371        lw/swfluxfile instead of lw/swdownfile in data.exf together with pkg/seaice
372    o testreport (& tools/do_tst_2+2):
373      - for MPI test, set default COMMAND to 'mpirun -v -np TR_NPROC ./{executable}'
374    o tools/build_options: linux_amd64_gfortran & linux_amd64_ifort11:
375      - remove CPP='cpp -traditional -P' (this is genmake2 default)
376      - add switch (for big setups) to use 'medium' memory-model (but leave it
377        commented out for now). Note: needed with FC 19 to compile big setups.
378    o pkg/atm_compon_interf:
379      - regroup per field origin (model & pkgs) the coupling storage routines
380         (which accumalate in time each coupling field)
381      - move bi,bj loops inside atm_store_my_data.F and store also wind-stress;
382        update accordingly + simplify aim_do_physics.F
383    
384    checkpoint64n (2013/08/26)
385    o pkg/bbl:
386      - update formulation to reduce dispersion of tracer properties in bbl
387      - replaced horizontal and vertical transport parameters with velocities
388      - changes results for verification/global_with_exf.yearly
389    o verification/halfpipe_streamice:
390      - change to matrix construction; update both Fwd & AD output.
391    o verification/tutorial_tracer_adjsens:
392      - OpenAD test: switch to vector-invariant momentum since fluxform with
393        rStar causes problems with OpenAD; update output.
394    o tools:
395      - genmake2: define a common prefix for all temp-file names ; move them
396        to local /tmp disk (but would be easy to move them back);
397      - xmakedepend: apply the same switch for temp-files.
398    o pkg/offline:
399      - changes for use with rStar (NLFS): assume that we continue to provide
400        UVELMASS/hFacW_ini & VVELMASS/hFacS_ini (hFacWi,S_ini as written in grid
401        output files) and apply r* scaling at each time-step (function of the time
402        varying Eta field); use normal pickup files (needed for restart with NLFS).
403    o adjoint with OpenAD:
404      - move OpenAD-specific files from verification/OpenAD/code_oad_all to a new
405        package openad.  This package has to be compiled for all runs with OpenAD
406        instead of specifying code_oad_all as a modification directory.
407      - link the fortran templates from tools/OAD_support to the build directory
408        for preprocessing to avoid conflicts between different setups compiled
409        simultaneously and simplify cleanup.
410    o pkg/exf:
411      - in exf_getforcing.F: comment out most of the EXCH calls (fields used by
412        main model or other pkgs are exchanged in EXF_MAPFIELDS).
413    o model/src:
414      - do_stagger_fields_exchanges.F: skip EXCH calls when using pkg/offline
415        (similar to do_fields_blocking_exchanges.F).
416    o tools/genmake2:
417      - remove TAF output src code just before calling staf (when not doing a fresh
418        built, will stop if things go wrong with staf).
419      - fix target "adobj" (left from TAF version-2 transition)
420    o pkg/diagnostics:
421      - add a parameter to track the status of pkg/diagnostics activation;
422        this replace/extend the use of logical param "settingDiags" (to check
423        when adding diag to the list) to also check any DIAGNOSTICS_[]FILL* call.
424        New S/R to print error message and stop when pkgStatus is not right.
425      - to try: add a warning when "data.diagnostics" exist but useDiagnostics=F.
426    
427    checkpoint64m (2013/08/13)
428    o model/inc:
429      - move FCORI_MACROS.h from PARAMS(_MACROS).h to GRID_MACROS.h (left from
430        8 yrs ago modif when Coriolis arrays were moved from PARAMS.h to GRID.h)
431    o pkg/kpp & aim_v23:
432      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
433    o pkg/seaice:
434      - restore (last time on 2011/12/24) ability to compile pkg/seaice with
435        undefined pkg/exf ALLOW_ATM_TEMP or ALLOW_RUNOFF CPP-options.
436      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
437    o eesupp/src:
438      - fix check for overlap-size argument (myOLn.GT.MAX_OLY_EXCH)
439        in exch1_rx[_ad].template (thanks to Francois Lefeuvre report).
440    o switch to TAF version-2:
441      - add flow directives to "freeze" naming convention for ad-routines that
442        are used in I/O routines of adjoint state and associated common blocks
443        that are used in adcommon.h (backward compatible with version-1)
444      - update all ad-optfiles (in tools/adjoint_options + few local to some
445        verification exp) to switch to latest TAF version (currently 2.5.5);
446        merge "*_mpi" adoptfiles into the corresponding non-mpi (but commented
447        out except for diva).
448      - the major change with TAF version-2 is that both the differentiated
449        routines and the forward routines (new) are returned as part of the TAF
450        output source code. Update genmake2 accordingly.
451      - new output for AD experiment tutorial_global_oce_biogeo (better AD gradient
452        with version-2 when compared to TLM or FWD gradient); other experiments
453        output show minor changes (machine truncation level); update the few AD &
454        TLM output with 12 matching digits only (some prior to version-2 switch).
455    
456    checkpoint64l (2013/08/05)
457    o model/src:
458      - in dynamics.F, skip the call to CALC_VISCOSITY if momViscosity=F
459      - main_do_loop.F: no longer includes additional (AUTODIFF) header files
460        when using TAF but only if using OpenAD.
461    o pkg/mom_common+fluxform+vecinv:
462      - always set horiz. viscosity arrays to background value before calling
463        MOM_CALC_VISC (in MOM_FLUXFORM & MOM_VECINV) and call S/R MOM_CALC_VISC
464        only when using variable horiz. viscosity (useVariableVisc=T);
465      - simplify mom_vecinv.F (only 1 block for momViscosity).
466    o pkg/mom_common: variable horiz. viscosity in NH code
467      - move horiz-viscosity 3-D arrays viscAh_W & viscA4_W (used in calc_gw.F)
468        from model/inc/NH_VARS.h to pkg/mom_common/MOM_VISC.h
469      - store in common block (in MOM_VISC.h) logical parameters: useHarmonicVisc,
470        useBiharmonicVisc & useVariableVisc.
471      - fix old bug (already in 1rst implementation of variable horizontal viscosity
472        in calc_gw.F, version 1.27, 2006/06/20):
473        horizontal bi-harmonic viscosity in gW was missing when wiscA4W=0
474        even if variable bi-harmonic viscosity (e.g., viscA4Grid) was non-zero.
475      - change background horiz viscosity in vertical momentum (gW) to always be
476        viscAhW,viscA4W (instead of switching to viscAhD, viscA4D when using
477        any type of variable viscosity, e.g., viscAh/4Grid)
478      - change default value of viscAhW,viscA4W to viscAhD,viscA4D (instead of
479        viscAh,viscA4) which default to viscAh,viscA4 :  this avoid missing
480        horiz. viscosity in W eq when just setting viscAhD/Z,viscA4D/Z (since
481        default viscAh,viscA4 is zero).
482    o model/src:
483      - extend length of drC & recip_drC from Nr to Nr+1.
484    o Divided Adjoint (DIVA) with MPI:
485      - genmake2: do not create local ./mpi_headers dir when no file to copy into.
486      - remove option ALLOW_DIVIDED_ADJOINT_MPI (replaced by ALLOW_DIVIDED_ADJOINT
487        and ALLOW_USE_MPI) from model/src code and from ECCO_CPPOPTIONS.h.
488    
489    checkpoint64k (2013/07/23)
490    o tools/OAD_support:
491      - avoid the need for file "oadtempflile" in insertTemplateDir.bash
492        and remove it from genmake2.
493    o tools/build_options:
494      - remove MPI_HEADER_FILES_INC setting (no longer used) and comment out
495        MPI_HEADER_FILES list (let genmake2 find the missing headers)
496    o verification/halfpipe_streamice:
497      - change to driving stress formulation; update both Fwd & AD output.
498    o tools/genmake2 and Divided Adjoint with MPI:
499      - remove default setting of MPIINCLUDEDIR from $MPIHOME (always been broken);
500      - only create local ./mpi_headers dir if using MPI and MPIINCLUDEDIR is set;
501      - add new variable (LOCAL_MPI_HEADERS, replace MPI_HEADER_FILES_INC) in
502        Makefile, which is set by genmake2, and check which mpi-headers are needed.
503        Note: need to update adjoint_options/adjoint_diva_mpi accordingly.
504      - update target "CLEAN" (to also remove ./mpi_headers/ dir).
505    o testreport:
506      - changes for Divided Adjoint Run: when file "run_ADM_DIVA" is present,
507        perform additional runs (number of additional runs is "add_DIVA_runs" taken
508        from file run_ADM_DIVA ; should match "nchklev_3" in file "code_ad/tamc.h").
509    o verification/lab_sea (AD test):
510      - change to test Divided Adjoint Run in this set-up (both standard AD test
511        and 2 secondary AD test: noseaice + noseaicedyn); drop the evp AD test.
512    o pkg atm_ & ocn_compon_interf:
513      - remove cpl_earlyExpImpCall=F option (was mainly a hack added for the old
514        staggerTimeStep implementation) and disable (retired) corresponding
515        parameter.
516    o pkg/offline:
517      - comment out unused field-array: ICEM, ConvectCount, hflx[01], icem[01];
518      - add S/R OFFLINE_CHECK to print offline parameter summary
519        and stop if loading a file that is not used;
520      - enable to calculate GMRedi tensor, KPP mixing and convective index
521        when the corresponding file(s) is/are not specified (but pkg is used).
522      - comment out resetting of monitorFreq (to endTime) since it still useful
523        for monitoring CFL numbers and checking offline fields.
524    o OpenAD:
525      - do not define OAD_DEBUG (in tools/adjoint_options/adjoint_oad) to get
526        smaller standard output) and generate new (smaller) output (on baudelaire
527        using gfortran with -ieee) for exp. tutorial_tracer_adjsens
528    o model/src:
529      - call EXTERNAL_FORCING_SURF outside bi,bj loops (in do_oceanic_phys.F),
530        (where external_forcing_adjust was called) and change list of arguments;
531      - merge external_forcing_adjust.F into external_forcing_surf.F
532      - put surface relaxation of SST & SSS in new S/R (forcing_surf_relax.F)
533        which also contains balancing surface relaxation (ALLOW_BALANCE_RELAX,
534        previously in file "balance_relax.F", now removed); remove corresponding
535        arrays in FFIELDS.h.
536      - EXTERNAL_FORCING_SURF is now called when using pkg/offline; implement
537        a hack for getting back surfaceForcingS (loaded from file) when using
538        ALLOW_OLD_VIRTUALFLUX (pkg/dic, in DIC_OPTIONS.h) in offline set-up.
539      - update output of AD test experiment global_ocean.cs32x15.seaice_dynmix
540        (was getting only 11 digits for AD-grad, due to different truncation
541         error in AD code).
542    
543    checkpoint64j (2013/07/04)
544    o pkg/offline:
545      - to enable the use of other features with pkg offline (e.g., obcs),
546        also call S/R DO_OCEANIC_PHYS in offline run - more modifs to come.
547      - comment out "allowFreezing" (now active) in 2 offline testing exp.
548    o pkg/exf ALLOW_RUNOFTEMP
549      - fix sign and make compatible with temp_EvPrRn .NE. UNSET_RL
550      - ahdded RUNOFTEMP test to verification/global_ocean.cs32x15/input.seaice
551      - changes verification/global_ocean.cs32x15/results/output.seaice.txt
552  o pkg/atm_phys:  o pkg/atm_phys:
553    - 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).
