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