4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7  o verification/isomip, pkg/shelfic and OpenAD:  o pkg/seaice:
8      - rename recently introduced parameters from (wrong name) AB to
9        BDF (backward difference time discretisation)
10      - retire runtime parameters SEAICEuseAB2, SEAICE_abEps
11    o tools/adjoint_options:
12      - remove setting of "OPENAD=true" (now set by command line "genmake2 -oad")
13    
14    checkpoint64t (2014/02/01)
15    o pkg/thsice
16      - corrected store directive fixes thsice adjoint gradient checks
17    o genmake2 & testreport:
18      - add genmake2 option "-oad" to generate a Makefile for OpenAD built and
19        in this case, use tools/adjoint_options/adjoint_oad as default AD optfile.
20        Update testreport accordingly. No need to set "export OPENAD=true"
21        in adjoint_options/adjoint_oad anymore (will be removed later).
22    o pkg/shelfice:
23      - put T & S shelfice forcing into model surfaceForcing_T,_S (for now,
24        only if SHELFICEboundaryLayer=F); Change model/src/external_forcing.F
25        so that surface forcing applies to k=kSurf if using pkg/shelfice.
26    o pkg/ctrl, pkg/grdchk, pkg/ecco:
27      - Changes to make GENARR more modular (i.e. invisible if not used)
28    o model/src/temp_integrate.F and salt_integrate.F
29      - re-include store directives that were removed on Dec 27th.
30    o model/src/external_forcing_surf.F
31      - add storage directives for EmPmR and PmEpR to avoid recomputation of
32        seaice_model in the adjoint that is problematic when seaice_model is
33        turned off in the adjoint. The resolved issue dated back to July when
34        EXTERNAL_FORCING_SURF call was moved.
35        Update global_ocean.cs32x15/*/output_adm.seaice_dynmix.txt accordingly.
36    o pkg/exf/exf_check.F
37      - fix a small bug again (originally found by Wentao Liu, now found again)
38      - streamline error output
39    o pkg/streamice and aim_v23:
40      - replace a few "_EXCH_XY_RL (" with "_EXCH_XY_RL(", so that
41        Apple's /usr/bin/cpp knows what to do:
42        Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)
43        Target: x86_64-apple-darwin13.0.0
44    
45    checkpoint64s (2014/01/05)
46    o tools/adjoint_options:
47      - switch to fastopt.net TAF server (instead of default fastopt.de) for
48        AD optfiles adjoint_diva & adjoint_f95 (similar to adjoint_default).
49    o model/src:
50      - remove some unnecessary TAF storage directives in forward_step.F and
51        in dynamics.F (note: not always removed by TAF, e.g., double storage
52        of kappaRU,kappaRV in former version of dynamics.F).
53    o model/src & pkg/ptracers:
54      - call directly GAD_IMPLICIT_R & IMPLDIFF + DWNSLP_APPLY from temp_integrate.F
55        salt_integrate.F and ptracers_integrate.F (instead of from thermodynamics.F)
56        and remove ptracers_dwnslp_apply.F & ptracers_implicit.F
57      - call MATRIX_STORE_TENDENCY_EXP for each tracer (in ptracers_integrate.F)
58      - add fZon & fMer as output argument of S/R GAD_CALC_RHS.
59      - update TAF AD-output of experiments global_ocean.90x40x15 (13 for AD-grad).
60    o useSingleCpuInput separates single-CPU input from single-CPU output;
61        for now only implemented for in exf_interp_read.F
62    o verification/advect_xy:
63      - fix missing EXCH call in local version of ini_salt.F and update output.
64    o momentum diagnostics:
65      - fix which deltaT is used in Total-Tendency diagnostics.
66      - fix typo in diagnostics for momentum tendency from AB.
67    o pkg/seaice/seaice_lsr.F: fix an initialisation bug for the
68        SEAICE_VECTORIZE_LSR_ZEBRA option that lead to NaNs on a NEC-SX8
69    
70    checkpoint64r (2013/12/08)
71    o verification/*/results:
72      - Update reference output of experiments that were passing with just 13 digits
73         (make it easier to detect future changes in results)
74    o model/src & pkg/ptracers:
75      - move calls to GAD_ADVECTION (Multi-Dim advection) from thermodynamics.F to
76        inside temp_integrate.F and salt_integrate.F and from ptracers_advection.F
77        to inside ptracers_integrate.F ; remove ptracers_advection.F
78    o coupling interface pkgs:
79        [atm_compon_interf, ocn_compon_interf & atm_ocn_coupler]
80      - change the config check to test the agreement of Ocean Depth
81        with ATM land/sea mask (instead of ATM orography);
82      - send to coupler the number of coupler time-steps to do for this run:
83        this allows to check for consistency and don't need anymore to be
84        specified in parameter file "data";
85      in coupler:
86      - check consistency of RunOff map versus Ocean Depth and ATM land/sea mask.
87      - improve report to log-file of config setting (pass log-file unit to few S/R)
88    o pkg/compon_communic:
89      - add coupling send/receive for non-tiled integer vector;
90      - add S/R to check and stop if any proc has an error (similar to
91        eesupp/src/stop_if_error.F but single thread and across Comm_World).
92    o pkg/exch2:
93      - in exch2*_get_rx[1,2]: use new list "W2_tileIndex" to replace search
94        through list of all tiles my proc owns.
95    o model/src:
96      - AUTODIFF only: in calc_adv_flow.F, recompute rTransKp (instead of copying
97        from rTrans) to simplify dependencies (no need to store rTrans anymore in
98        calling S/R); this affects AD results at machine truncation level:
99        update AD-output (TAF) of experiments: 1D_ocean_ice_column,
100        bottom_ctrl_5x5 & obcs_ctrl (12 digits for AD grad, same FWD grad).
101    o tools/build_options:
102      - simplify Warnings options (-ieee & -devel cases) in linux_amd64_gfortran
103    o coupling interface pkgs:
104        [compon_communic, atm_compon_interf & ocn_compon_interf]
105      - move declaration of local array "ibuf" out of header file "CPLR_SIG.h"
106        to each S/R that needs it; remove un-used variables.
107      - change component tile registration (cpl_register.F in both compon_interf
108        and mitcomponent_tile_register.F) to pass the full list of tiles
109        information (including bi,bj) in 1 vector (instead of in a bi,bj matrix).
110      - with pkg/exch2: adopt the same convention used for I/O to define mapping
111        towards coupler global array (unless W2_useE2ioLayOut=F):
112         a) can now use different tiling between atm & ocn comp.
113         b) no needs to modify the run-Off map when changing tiling (was needed
114            even if using the same tiling between atm & ocn).
115         c) will allow to run with blank-tiles in 1 component (e.g., for ocean
116            full land tiles); not yet tested.
117      - check for valid mapping from comp. tile to coupler global array
118      - improve report of tile registration results to log file.
119    o pkg/exch2:
120      - in eesupp/src/eeboot.F: move call to W2_EEBOOT before Coupler
121        tile-registration (CPL_REGISTER);
122      - activate (un-comment) definition and setting of "W2_tileIndex" list to
123        store the local bi,bj indices of each tile;
124      - also print bi,bj in local report to log file;
125      - fix pkg/debug/debug_cs_corner_uv.F for the case nSy > 1 (left from
126        Jun 2009 modif of pkg/exch2).
127    o testing on baudelaire:
128      - run 2 tests at a time: no significant slow down (since enough cpu) and
129        get the full set of test done earlier
130      - switch the ifort test to "-devel" ; run the OpenAD test everyday.
131    o model/src/thermodynamics.F and routines called from it:
132      - pkg/gmredi: gmredi_residual_flow.F (replacing gmredi_calc_uvflow.F &
133        gmredi_calc_wflow.F) to update eulerian velocity (input) into residual
134        velocity (outp) by adding bolus velocity.
135      - model/src: calc_adv_flow.F (replacing calc_common_factors.F) to compute
136        mass transport from velocity + lateral grid cell area
137      - rename calc_gt.F to temp_integrate.F (includes call to TIMESTEP_TRACER)
138      - rename calc_gs.F to salt_integrate.F (includes call to TIMESTEP_TRACER)
139     in thermodynamics.F
140      - remove k from thermodynamics.F and move it to temp_integrate.F
141        salt_integrate.F and ptracers_integrate.F (now done inside the tracer
142        loop).
143      - compute locally (in thermodynamics.F) 3-D velocity field that is used to
144        advect tracers; pass it as argument to GAD_ADVECTION, GAD_SOM_ADVECT,
145        PTRACERS_ADVECTION, TEMP_INTEGRATE, SALT_INTEGRATE, PTRACERS_INTEGRATE,
146        GAD_IMPLICIT_R and PTRACERS_IMPLICIT
147      - update AD-output (TAF & OAD) of experiments: 1D_ocean_ice_column,
148        global_ocean.90x40x15, tutorial_global_oce_biogeo and
149        tutorial_tracer_adjsens (+ TLM output).
150    o tools/OAD_support and (verification/*/) code_oad:
151      - OAD_support/cb2mGetModules.csh: add PACKAGES_CONFIG.h in header file to
152        module conversion ; remove unneeded CPP_EEOPTIONS.h.
153      - code_oad/CPP_OPTIONS.h: remove PACKAGES_CONFIG.h and use a more standard
154        version (closer to model/inc/CPP_OPTIONS.h).
155    o model/src:
156      - remove parameter "useOldFreezing" from PARAMS.h and push it to the
157        retired list of parameters (routine FREEZE has been replace by surface
158        freezing (10.yrs ago) and by pkg/frazil (interior freezing).
159    o pkg/gmredi:
160      - add option (GM_CALC_TRANSP_FROM_VEL) to compute transport directly from
161        velocity (same scheme but affects machine truncation) for GM_AdvForm.
162      - update output of FWD experiments: front_relax.bvp,
163        global_ocean.90x40x15.dwnslp, global_ocean.cs32x15 and ideal_2D_oce.
164    
165    checkpoint64q (2013/11/17)
166    o verification:
167      - generate new output on baudelaire (gfortran, -ieee) for OpenAD experiments
168        tutorial_global_oce_biogeo and global_ocean.90x40x15.
169      - generate new output (growth & melt) for seaice_itd experiment after
170        updating the input pickup_seaice files (previously wrong).
171    o pkg/cost:
172      - define a "final cost function" for each tile, and use GLOBAL_SUM_TILE_RL
173        (instead of _GLOBAL_SUM_RL) to get the final cost from all procs & threads:
174        o this fixes global-sum value if multi-threads (since GLOBAL_SUM_RL
175          cannot be applied to var in common block).
176        o allows to get results independent of tile-per-proc setting (if using
177          slower GLOBAL_SUM_SEND_RECV option).
178      - update accordingly: seaice_cost_final.F, shelfice_cost_final.F,
179        thsice_cost_final.F and ecco_cost_final.F (this one affects lab_sea
180        forward gradients: update output).
181      - update */code_oad/externalDummies.F by adding dummy GLOBAL_SUM_TILE_RL
182        S/R and, for most exp., also comment out GLOBAL_SUM_R8.
183    o pkg/mom_common:
184      - move to pkg/mom_common and model/src (previously in tutorial_deep_convection
185        code) 2nd version of isotropic 3-D Smagorinsky code interface: strain and
186        viscosity are locally declared in dynmics.F and pass as argument to CALC_GW;
187        ensure that all field value that are used are set.
188    o tutorial_deep_convection (smag3d):
189      - add missing scaling in mom_calc_smag_3d.F;
190      - set smag3D_coeff in input.smag3d such that results do not change.
191    o pkg/dic:
192      - change dic_cost.F to compute cost on each tile first and then apply
193        GLOBAL_SUM_TILE_RL: this affects forward gradient of AD experiments
194        tutorial_dic_adjoffline & tutorial_global_oce_biogeo; update output.
195      - remove kLev argument and use GLOBAL_SUM_TILE_RL in tracer_meanarea.
196    o eesupp/src & pkg/mdsio:
197      - remove gather/scatter_vector.F (from eesupp) and mdsio_read/writevector.F
198        (from pkg/mdsio) since they are no longer used for tape IO.
199      - move simple C subroutine "setdir.c" from pkg/compon_communic to eesupp/src
200        (+ keep a copy in pkg/atm_ocn_coupler).
201    o verification/isomip:
202      - split domain in 8 squared tiles (instead of just 2) for FWD, AD & OAD tests.
203    o tools/build_options:
204      - optfile linux_amd64_ifort11, fast (no ieee) case:
205        to get a working restart for all experiments, add "-fp-model source"
206        to FOPTIM (also remove "-opt-streaming-stores auto" <- this is the default).
207    
208    checkpoint64p (2013/10/20)
209    o pkg/autodiff:
210      - adread_adwrite.F: when type and length do not match ALLOW_AUTODIFF_WHTAPEIO
211        criteria, return to simple (default) tape IO format.
212    o pkg/mdsio (+ eesupp/src):
213      - rewrite/simplify tape-IO S/R (new S/R MDS_READ/WRITE_TAPE replace
214        previous MDSREAD/WRITEVECTOR) with 2 array argument from each type (R4/R8);
215      - fix globalFile and singleCpuIO options using simpler global mapping.
216      - new pairs of scatter/gather vector S/R (one for each type, generated from
217        template) corresponding to simpler global mapping.
218      - adread_write.F: switch to new S/R (but leave old calls commented) and write
219        to globalFile when parameter globalFiles is set to True.
220      - switch on useSingleCpuIO in AD experiments: global_ocean.90x40x15 & isomip.
221    o pkg/autodiff:
222      - adread_adwrite.F: add a hack for RS arrays (when RS=real*4);
223        with ALLOW_AUTODIFF_WHTAPEIO defined, since corresponding (real*4) is
224        missing, just add a STOP if array type do not match.
225    o pkg/exf:
226      - to allow to use seaice-fraction from pkg/exf in other pkgs than pkg/seaice:
227         rename CPP option EXF_ALLOW_SEAICE_RELAX to EXF_SEAICE_FRACTION
228         and rename array obsSIce to exf_iceFraction.
229    o tutorial_deep_convection:
230      - add 1rst version of isotropic 3-D Smagorinsky code (from Louis-Philippe),
231        for now all in this exp. code dir.
232      - add secondary test using Smag-3D viscosity (keep very low backgroud visc for
233        testing) and flux-limter advection scheme for Temp. (no explicit diffusion).
234    o eesupp/src:
235      - added SINGLE_DISK_IO option because reading of parameter files on
236        very large number of processors did not work with existing set-up
237    
238    checkpoint64o (2013/09/25)
239    o pkg/atm_phys & atm_compon_interf:
240      - allows for coupling of gray-atmosphere (atm_phys) with ocean.
241    o tools/build_options:
242      - switch from "-fPIC" to "-mcmodel=medium" in optfiles: linux_amd64_gfortran
243        & linux_amd64_ifort11 and in linux_amd64_g77 & linux_amd64_open64 also
244        remove CPP setting (was identical to genmake2 default).
245    o pkg/gmredi & model/src: Some updating and work done on the residual model.
246      - created new file model/src/calc_eddy_stress.F to calculate the eddy stress.
247      - fixed up the calculation of the eddy stress and how it is added to the
248        external forcing via taueddy_external_forcing.F
249      - at the moment, it is very experimental and only works with the variable eddy
250        diffusivity calculated in gmredi_k3d.F
251    o pkg/seaice/seaice_check.F: add a check to catch the case of specifying
252        lw/swfluxfile instead of lw/swdownfile in data.exf together with pkg/seaice
253    o testreport (& tools/do_tst_2+2):
254      - for MPI test, set default COMMAND to 'mpirun -v -np TR_NPROC ./{executable}'
255    o tools/build_options: linux_amd64_gfortran & linux_amd64_ifort11:
256      - remove CPP='cpp -traditional -P' (this is genmake2 default)
257      - add switch (for big setups) to use 'medium' memory-model (but leave it
258        commented out for now). Note: needed with FC 19 to compile big setups.
259    o pkg/atm_compon_interf:
260      - regroup per field origin (model & pkgs) the coupling storage routines
261         (which accumalate in time each coupling field)
262      - move bi,bj loops inside atm_store_my_data.F and store also wind-stress;
263        update accordingly + simplify aim_do_physics.F
264    
265    checkpoint64n (2013/08/26)
266    o pkg/bbl:
267      - update formulation to reduce dispersion of tracer properties in bbl
268      - replaced horizontal and vertical transport parameters with velocities
269      - changes results for verification/global_with_exf.yearly
270    o verification/halfpipe_streamice:
271      - change to matrix construction; update both Fwd & AD output.
272    o verification/tutorial_tracer_adjsens:
273      - OpenAD test: switch to vector-invariant momentum since fluxform with
274        rStar causes problems with OpenAD; update output.
275    o tools:
276      - genmake2: define a common prefix for all temp-file names ; move them
277        to local /tmp disk (but would be easy to move them back);
278      - xmakedepend: apply the same switch for temp-files.
279    o pkg/offline:
280      - changes for use with rStar (NLFS): assume that we continue to provide
281        UVELMASS/hFacW_ini & VVELMASS/hFacS_ini (hFacWi,S_ini as written in grid
282        output files) and apply r* scaling at each time-step (function of the time
283        varying Eta field); use normal pickup files (needed for restart with NLFS).
284    o adjoint with OpenAD:
285      - move OpenAD-specific files from verification/OpenAD/code_oad_all to a new
286        package openad.  This package has to be compiled for all runs with OpenAD
287        instead of specifying code_oad_all as a modification directory.
288      - link the fortran templates from tools/OAD_support to the build directory
289        for preprocessing to avoid conflicts between different setups compiled
290        simultaneously and simplify cleanup.
291    o pkg/exf:
292      - in exf_getforcing.F: comment out most of the EXCH calls (fields used by
293        main model or other pkgs are exchanged in EXF_MAPFIELDS).
294    o model/src:
295      - do_stagger_fields_exchanges.F: skip EXCH calls when using pkg/offline
296        (similar to do_fields_blocking_exchanges.F).
297    o tools/genmake2:
298      - remove TAF output src code just before calling staf (when not doing a fresh
299        built, will stop if things go wrong with staf).
300      - fix target "adobj" (left from TAF version-2 transition)
301    o pkg/diagnostics:
302      - add a parameter to track the status of pkg/diagnostics activation;
303        this replace/extend the use of logical param "settingDiags" (to check
304        when adding diag to the list) to also check any DIAGNOSTICS_[]FILL* call.
305        New S/R to print error message and stop when pkgStatus is not right.
306      - to try: add a warning when "data.diagnostics" exist but useDiagnostics=F.
307    
308    checkpoint64m (2013/08/13)
309    o model/inc:
310      - move FCORI_MACROS.h from PARAMS(_MACROS).h to GRID_MACROS.h (left from
311        8 yrs ago modif when Coriolis arrays were moved from PARAMS.h to GRID.h)
312    o pkg/kpp & aim_v23:
313      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
314    o pkg/seaice:
315      - restore (last time on 2011/12/24) ability to compile pkg/seaice with
316        undefined pkg/exf ALLOW_ATM_TEMP or ALLOW_RUNOFF CPP-options.
317      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
318    o eesupp/src:
319      - fix check for overlap-size argument (myOLn.GT.MAX_OLY_EXCH)
320        in exch1_rx[_ad].template (thanks to Francois Lefeuvre report).
321    o switch to TAF version-2:
322      - add flow directives to "freeze" naming convention for ad-routines that
323        are used in I/O routines of adjoint state and associated common blocks
324        that are used in adcommon.h (backward compatible with version-1)
325      - update all ad-optfiles (in tools/adjoint_options + few local to some
326        verification exp) to switch to latest TAF version (currently 2.5.5);
327        merge "*_mpi" adoptfiles into the corresponding non-mpi (but commented
328        out except for diva).
329      - the major change with TAF version-2 is that both the differentiated
330        routines and the forward routines (new) are returned as part of the TAF
331        output source code. Update genmake2 accordingly.
332      - new output for AD experiment tutorial_global_oce_biogeo (better AD gradient
333        with version-2 when compared to TLM or FWD gradient); other experiments
334        output show minor changes (machine truncation level); update the few AD &
335        TLM output with 12 matching digits only (some prior to version-2 switch).
336    
337    checkpoint64l (2013/08/05)
338    o model/src:
339      - in dynamics.F, skip the call to CALC_VISCOSITY if momViscosity=F
340      - main_do_loop.F: no longer includes additional (AUTODIFF) header files
341        when using TAF but only if using OpenAD.
342    o pkg/mom_common+fluxform+vecinv:
343      - always set horiz. viscosity arrays to background value before calling
344        MOM_CALC_VISC (in MOM_FLUXFORM & MOM_VECINV) and call S/R MOM_CALC_VISC
345        only when using variable horiz. viscosity (useVariableVisc=T);
346      - simplify mom_vecinv.F (only 1 block for momViscosity).
347    o pkg/mom_common: variable horiz. viscosity in NH code
348      - move horiz-viscosity 3-D arrays viscAh_W & viscA4_W (used in calc_gw.F)
349        from model/inc/NH_VARS.h to pkg/mom_common/MOM_VISC.h
350      - store in common block (in MOM_VISC.h) logical parameters: useHarmonicVisc,
351        useBiharmonicVisc & useVariableVisc.
352      - fix old bug (already in 1rst implementation of variable horizontal viscosity
353        in calc_gw.F, version 1.27, 2006/06/20):
354        horizontal bi-harmonic viscosity in gW was missing when wiscA4W=0
355        even if variable bi-harmonic viscosity (e.g., viscA4Grid) was non-zero.
356      - change background horiz viscosity in vertical momentum (gW) to always be
357        viscAhW,viscA4W (instead of switching to viscAhD, viscA4D when using
358        any type of variable viscosity, e.g., viscAh/4Grid)
359      - change default value of viscAhW,viscA4W to viscAhD,viscA4D (instead of
360        viscAh,viscA4) which default to viscAh,viscA4 :  this avoid missing
361        horiz. viscosity in W eq when just setting viscAhD/Z,viscA4D/Z (since
362        default viscAh,viscA4 is zero).
363    o model/src:
364      - extend length of drC & recip_drC from Nr to Nr+1.
365    o Divided Adjoint (DIVA) with MPI:
366      - genmake2: do not create local ./mpi_headers dir when no file to copy into.
367      - remove option ALLOW_DIVIDED_ADJOINT_MPI (replaced by ALLOW_DIVIDED_ADJOINT
368        and ALLOW_USE_MPI) from model/src code and from ECCO_CPPOPTIONS.h.
369    
370    checkpoint64k (2013/07/23)
371    o tools/OAD_support:
372      - avoid the need for file "oadtempflile" in insertTemplateDir.bash
373        and remove it from genmake2.
374    o tools/build_options:
375      - remove MPI_HEADER_FILES_INC setting (no longer used) and comment out
376        MPI_HEADER_FILES list (let genmake2 find the missing headers)
377    o verification/halfpipe_streamice:
378      - change to driving stress formulation; update both Fwd & AD output.
379    o tools/genmake2 and Divided Adjoint with MPI:
380      - remove default setting of MPIINCLUDEDIR from $MPIHOME (always been broken);
381      - only create local ./mpi_headers dir if using MPI and MPIINCLUDEDIR is set;
382      - add new variable (LOCAL_MPI_HEADERS, replace MPI_HEADER_FILES_INC) in
383        Makefile, which is set by genmake2, and check which mpi-headers are needed.
384        Note: need to update adjoint_options/adjoint_diva_mpi accordingly.
385      - update target "CLEAN" (to also remove ./mpi_headers/ dir).
386    o testreport:
387      - changes for Divided Adjoint Run: when file "run_ADM_DIVA" is present,
388        perform additional runs (number of additional runs is "add_DIVA_runs" taken
389        from file run_ADM_DIVA ; should match "nchklev_3" in file "code_ad/tamc.h").
390    o verification/lab_sea (AD test):
391      - change to test Divided Adjoint Run in this set-up (both standard AD test
392        and 2 secondary AD test: noseaice + noseaicedyn); drop the evp AD test.
393    o pkg atm_ & ocn_compon_interf:
394      - remove cpl_earlyExpImpCall=F option (was mainly a hack added for the old
395        staggerTimeStep implementation) and disable (retired) corresponding
396        parameter.
397    o pkg/offline:
398      - comment out unused field-array: ICEM, ConvectCount, hflx[01], icem[01];
399      - add S/R OFFLINE_CHECK to print offline parameter summary
400        and stop if loading a file that is not used;
401      - enable to calculate GMRedi tensor, KPP mixing and convective index
402        when the corresponding file(s) is/are not specified (but pkg is used).
403      - comment out resetting of monitorFreq (to endTime) since it still useful
404        for monitoring CFL numbers and checking offline fields.
405    o OpenAD:
406      - do not define OAD_DEBUG (in tools/adjoint_options/adjoint_oad) to get
407        smaller standard output) and generate new (smaller) output (on baudelaire
408        using gfortran with -ieee) for exp. tutorial_tracer_adjsens
409    o model/src:
410      - call EXTERNAL_FORCING_SURF outside bi,bj loops (in do_oceanic_phys.F),
411        (where external_forcing_adjust was called) and change list of arguments;
412      - merge external_forcing_adjust.F into external_forcing_surf.F
413      - put surface relaxation of SST & SSS in new S/R (forcing_surf_relax.F)
414        which also contains balancing surface relaxation (ALLOW_BALANCE_RELAX,
415        previously in file "balance_relax.F", now removed); remove corresponding
416        arrays in FFIELDS.h.
417      - EXTERNAL_FORCING_SURF is now called when using pkg/offline; implement
418        a hack for getting back surfaceForcingS (loaded from file) when using
419        ALLOW_OLD_VIRTUALFLUX (pkg/dic, in DIC_OPTIONS.h) in offline set-up.
420      - update output of AD test experiment global_ocean.cs32x15.seaice_dynmix
421        (was getting only 11 digits for AD-grad, due to different truncation
422         error in AD code).
423    
424    checkpoint64j (2013/07/04)
425    o pkg/offline:
426      - to enable the use of other features with pkg offline (e.g., obcs),
427        also call S/R DO_OCEANIC_PHYS in offline run - more modifs to come.
428      - comment out "allowFreezing" (now active) in 2 offline testing exp.
429    o pkg/exf ALLOW_RUNOFTEMP
430      - fix sign and make compatible with temp_EvPrRn .NE. UNSET_RL
431      - ahdded RUNOFTEMP test to verification/global_ocean.cs32x15/input.seaice
432      - changes verification/global_ocean.cs32x15/results/output.seaice.txt
433    o pkg/atm_phys:
434      - allows to add some damping on uVel,vVel (strength only function of k).
435    o verification, ad-tests:
436      - reduce length of the simulation for AD test: global_ocean.cs32x15.seaice,
437        global_ocean_ebm and offline_exf_seaice.thsice.
438    o verification/halfpipe_streamice:
439      - found a bug in s/r pkg/streamice/streamice_advect_thickness which caused
440        flux input boundary conditions to be ignored; a fix for this bug changed
441        verification results for forward test.
442      - add adjoint test.
443    o pkg/ptracers:
444      - allow to restart without SOM pickup (resetting SOM to zero).
445    o pkg/gmredi:
446      - New parameterisation for the calculation of K and (GM_PsiX,GM_PsiY) added.
447      - It uses mixing length theory and suppression by steering level effects to
448        calculate a diffusivity used in the Redi tensor (see Bates et al., submitted
449        to JPO, for more details).
450      - It also uses the diffusivity to calculate an eddy induced streamfunction
451        based on a PV closure (rather than a buoyancy closure as in GM).
452      - New files added to pkg/gmredi:
453        gmredi_k3d.F calculates the diffusivity for the Redi tensor and the eddy
454          induced overturning streamfunction (called from gmredi_calc_tensor)
455        gmredi_calc_eigs.F calculates the eigenvalues and eigenvectors required
456          for use in gmredi_k3d
457        gmredi_calc_urms.F calculates the the rms eddy velocity used to calculate
458          the eddy diffusivity
459    
460    checkpoint64i (2013/06/18)
461    o pkg/cheapaml:
462      - take src files from MITgcm_contrib/verification_other/offline_cheapaml/code
463        that enable the use of seaice (pkg/thsice thermo & pkg/seaice dynamics)
464        with pkg/cheapaml.
465    o utils/python: add subpackage for cubed sphere function, first example is
466        simple cs.pcol to plot 2D fields on a map
467    o pkg/streamice:
468      - This is a new package in MITgcm, which solves dynamic equations for ice
469         sheets and ice streams
470      - At the moment it is independent of atmosphere/ocean dynamics, or any
471        other physical packages in MITgcm, even ShelfIce (although it is anticipat-
472        ed that this will change)
473      - There is a new verification exercise that tests it, halfpipe_streamice,
474        evolves a 40x80 km ice stream/ice shelf (at coarse resolution) in a
475        rectangular embayment
476      - halfpipe_streamice is forward-only for now, will have TAF test soon
477      - for questions, email dgoldber@mit.edu
478    o pkg/thsice:
479      - fix filling of snow-precip diagnostic (SIsnwPrc) (left from the removing
480        of snowPrc from common bloc, on May 2nd, thsice_step_fwd.F revision 1.40);
481      - remove diagnostics 'SI_FrcFx' ( now identical to 'SI_Fract' with new
482         call sequence: ice-Thermo(thsice),ice-Dyn,ice-Advect );
483      - allow precip from pkg/cheapaml to make snow over seaice.
484    o pkg/cfc:
485      - move in separated header file (CFC_ATMOS.h) time-serie arrays of Atmos CFC
486      - remove atmos CFC 2-D arrays from common bloc (now local variables)
487      - change some hard-coded constant to run time parameter for reading and
488        and interpolating atmospheric CFC ; keep same default as previously.
489      - more flexible reading of Atmos CFC (number of records no longer hard-coded)
490      - put arguments in standard order: myTime, myIter, myThid
491      - use standard S/R GET_PERIODIC_INTERVAL for time interpolation of
492        atmospheric CFC ; fix for the case myIter < PTRACERS_iter0.
493      - fix calculation of surf tendencys for partial-cell and/or Non-Lin Free-Surf
494      - new routine to print summary of CFC params and check for consistency.
495    o pkg/seaice: add uice/vice to the parameter list of s/r seaice_advdiff,
496      similar to thsice_advdiff.
497      Note that for the B-grid case the routine parameters uc/vc are overwritten.
498    o pkg/cfc:
499      - change time interpolation for atmospheric CFC-11 (now same as for CFC-12);
500        update output (CFC-11) of experiment cfc_example and tutorial_cfc_offline.
501      - fix interpolation of atmphspheric CFC between Sorthern and Northern
502        hemisphere value.
503    o pkg/seaice:
504      - allow to use seaice dynamics without pkg/exf (e.g., using pkg/cheapaml)
505    o pkg/seaice: add Adams-Bashforth2 time discretization for ice dynamics;
506                  so far only for JFNK-solver, turn on with SEAICEuseAB2 = .TRUE.
507      - requires an additional time level that is stored in the pickup
508      - you can start with AB2 from a pickup without this time level with
509        pickupStrictlyMatch = .false.
510    
511    checkpoint64h (2013/05/26)
512    o pkg/cheapaml:
513      - replace one ()**.5 with SQRT + use temp var "cdu = tau/Du" (coare3_flux);
514        affect machine truncation (but exp cheapAML_box still pass with 13 digits).
515      - consistent treatment of uWind,vWind location: assume everywhere in
516        pkg/cheapaml that they are on C-grid (@ uVel,vVel location)
517        (Note: was already the case for Tair,Qair advection);
518        add option (INCONSISTENT_WIND_LOCATION) to recover old results.
519      - compute diabatic forcing only in the interior (excluding overlap regions)
520      - fill in array "Qsw" (for short-wave heating);
521      - add diagnostic for precip ; fill-in diagnostics for cheapAML state vars
522        before any update (consistent with MITgcm state var diagnostics);
523      - cheapaml_fields_load.F & cheapaml_init_varia.F : only fill outer edges if
524        non periodic ; + adjusted for uWind,vWind (C-grid).
525    o pkg/seaice:
526      - remove dependence of pkg/seaice versus pkg/exf (file: pkg/pkg_depend) and
527        add explicitly pkg/exf in experiments that currently use pkg/seaice.
528      - allows to compile pkg/seaice without pkg/exf.
529    o tools/OAD_support:
530      - use a local copy (ourRWCPinBd) to ensure index ourRWCP stays within bounds
531        of array "ourStepOf" in function rvNextAction (revolve.F90).
532    o pkg/aim_compon_interf renamed to pkg/atm_compon_interf
533      - change pkg name (to be used with other atmospheric physics pkg)
534        but by-pass CVS when making the new pkg so that we keep the CVS history.
535    o pkg/offline:
536      - call OFFLINE_FIELDS_LOAD from pkg/offline/offline_init_varia.F
537        (previously called from pkg/dic_surfforcing_init.F)
538    o model/src:
539      - re-order sequence of calls within packages_init_variables.F, using
540        standard order, except for:
541         DIAGNOSTICS_INIT_VARIA and OFFLINE_INIT_VARIA (called @ the top),
542         CTRL_MAP_INI and OBCS_INIT_VARIABLES (called @ the bottom)
543    o new pkg: atm_phys
544      - add entry point and source code (previously in contrib
545          verification_other/atm_gray/code_gray/) for new pkg "atm_phys"
546        (atmospheric physics pkg from P. O'Gorman and T. Schneider, JCl, 2008).
547      - re-order sequence of calls within packages_readparms.F,
548         packages_init_fixed.F and packages_write_pickup.F
549        (but skip packages_init_variables.F because of TAF issues).
550      - update contrib/*/atm_gray/ experiment.
551    o pkg/seaice (ITD code):
552      - simplify and fix the writing of pickup-files for ITD case
553    o pkg/seaice (ITD code):
554      - introduce floe size dependent lateral melt for ITD case;
555      - cleaning (avoid division by zero, change to f77 syntax, remove tabs)
556      - update seaice_itd experiment main output.
557    o pkg/thsice:
558      - remove snowPrc from common block THSICE_FLUX, in THSICE_VARS.h and
559        declared it locally (without bi,bj) in thsice_main.F & aim_do_physics.F;
560        changed accordingly pkg/atm2d.
561    
562    checkpoint64g (2013/05/01)
563    o pkg/exf ALLOW_RUNOFTEMP
564      - if defined,  river and glacier runoff temperature can be read-in from
565        runoftempfile; runoftempfile needs to have same format as runofffile
566    o pkg/thsice (& pkg/bulk_force):
567      - In case Energy-Reference-Level (ERL) is used (temp_EvPrRn=0), account
568        for energy content of Precip + RunOff & Evap (like with pkg/exf).
569      - change computation domain to always be the interior (without overlap).
570      - fix bug (wrong overlap) when using EXF and stressReduction > 0.
571    o verification/tutorial_global_oce_biogeo:
572      - add preliminary OpenAD setup (still has problems)
573    o pkg/seaice:
574      - turn some parameters for choosing the convergence criterion of
575        the inexact Newton method (JFNK) into runtime parameters for convenience
576      - clean up seaice_calc_viscosities.F: remove/retire two options for
577        SEAICetaZmethod (1,2), introduce area weighting for method 3; this changes
578        the results of lab_sea/input because a division has been replaced by
579        a multiplication with the reciprocal (sumNorm)
580      - modify offline_exf_seaice/input.dyn_jfnk/data.seaice to improve
581        convergence of solver (changes results, of course), and to test some
582        new features
583    o model/src:
584      - remove unused (since Aug 2006) S/R SET_WRITE_GLOBAL_PICKUP and its call.
585      - remove unused forcing field "dQdT" and associated parameter "dQdTFile".
586      - move forcing adjustment (balancing surface forcing) in specific S/R
587        where might also be applied exchanges (if needed) to forcing arrays.
588    o pkg/shelfice:
589      - allow to specify the Ice-Shelf mass per unit area (instead of
590        shelficeLoadAnomaly) and do the conversion from one to the other
591      - move loading from file of shelficeLoadAnomaly from SHELFICE_INIT_VARIA
592        to SHELFICE_INIT_FIXED: (a) avoid some TAF recompution issues and
593        (b) will be loaded in time (before calling INI_PRESSURE) in case it is
594        needed in phi0surf for initial pressure calculation when useDynP_inEos_Zc
595      - update isomip experiment forward output (get machine truncation error
596        from conversion shelficeLoadAnomaly -> shelficeMass -> shelficeLoadAnomaly)
597    o verification/offline_exf_seaice:
598      revise data.seaice in input.thermo and input_ad and update results accordingly
599        HO = 0.2, SEAICE_areaLossFormula = 2,
600        SEAICE_growMeltByConv = .TRUE.,
601        SEAICE_doOpenWaterMelt = .TRUE.,
602      Improve consistency with input.thsice and fix the spurious 500m ice corners
603    o verification/global_ocean.cs32x15:
604      - set Energy Reference Level to liq. water @ 0 degC: temp_EvPrRn=0.,
605        in icedyn (thsice+seaice-dyn) test and update output.
606    o verification/offline_exf_seaice:
607      - adjust list of tested variables (with testreport) and update
608        standard test output with better slection of monitored fields.
609    o pkg/cd_code:
610      - swtich off Adams-Bashforth on the 1rst iteration. Update output of
611        experiment lab_sea.hb87
612    o tools/genmake2:
613      - change default makedepend from the system default to tools/xmakedepend:
614        When no makedepend is specified, select tools/xmakedepend it the test pass,
615        otherwise select the system default (if exist and pass the test) or
616        try to build cyrus-makedepend ; stop if none of the 3 works.
617    o pkg/exf & pkg/thsice:
618      - In case Energy-Reference-Level (ERL) is used (temp_EvPrRn=0), account
619        for energy content of Precip + RunOff & Evap. Assumes:
620       1) Rain has same temp as Air.
621       2) Snow has no heat capacity (consistent with seaice & thsice pkgs)
622       3) Run-Off comes at the temp of surface water (with same Cp)
623       4) Evap over ocean is released to the Atmos @ surf-temp (=SST); should be
624        put directly into Latent Heat flux & should use water-vapor heat capacity.
625       5) Evap over snow/seaice (pkg/thsice) assumes constant Lf+Lv (consistent
626        with snow having no Cp) => water vapor is released to Atmos @ 0^oC (=ERL).
627    o pkg/seaice: simplify the use of CPP flags in JFNK-related files
628        (compile when SEAICE_ALLOW_JFNK is defined)
629    o pkg/thsice:
630      - fix oceanic flux diagnostics & timeave (left from new sequence of calls
631        implementation): move THSICE_AVE call after the advection (called directly
632        from thsice_do_advect.F).
633    o verification/global_ocean.90x40x15 and OpenAD:
634      New experiment for OpenAD is identical to the one in input_ad except that
635        multiDimAdvection=.FALSE.,
636      There is still an issue with this.
637    o pkg/thsice:
638      - account for ice velocity (ocean relative velocity) in turbulent heat flux
639        at the base of the ice; update output of global_ocean.cs32x15 (icedyn)
640        and offline_exf_seaice (main test).
641    
642    checkpoint64f (2013/03/31)
643    o verification/OpenAD:
644      - new (smaller, without OAD_DEBUG) output_oadm.txt generated using gfortran.
645    o verification/isomip, pkg/shelfice and OpenAD:
646    - add OpenAD setup to this exp and make shelfice package work with OpenAD    - add OpenAD setup to this exp and make shelfice package work with OpenAD
647  o verification/offline_exf_seaice: replace adjoint experiment.  o verification/tutorial_global_oce_biogeo:
648      - update AD and TLM output after turning off ALLOW_FE (in DIC_OPTIONS.h)
649    o verification/offline_exf_seaice:
650      - replace adjoint experiment (now similar to fwd input.thermo/ setup).
651  o verification/tutorial_tracer_adjsens, pkg/ptracers and OpenAD:  o verification/tutorial_tracer_adjsens, pkg/ptracers and OpenAD:
652    - add OpenAD setup to this exp and make ptracers package work with OpenAD    - add OpenAD setup to this exp and make ptracers package work with OpenAD
653  o pkg/seaice/seaice_evp.F: mask the asymmetric contribution of the ice-ocean  o pkg/seaice/seaice_evp.F:
654    stress (when the turningAngle is non-zero) over open water to avoid     mask the asymmetric contribution of the ice-ocean stress (when
655    stripes in the EVP-solutions after many EVP-substeps. This does not change     the turningAngle is non-zero) over open water to avoid stripes

657    will affect other EVP solutions with turningAngle.ne.0     the verification experiment (because turningAngle=0 in that experiment),
658       but will affect other EVP solutions with turningAngle.ne.0
659  o verification, AD & TLM output:  o verification, AD & TLM output:
660    - new TAF version 2.3.10 (previously 2.3.8) add more parenthesis in multiple    - new TAF version 2.3.10 (previously 2.3.8) add more parenthesis in multiple
