4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7  o pkg/seaice: fix line search in seaice_jfnk.F (s/r seaice_jfnk_update)  checkpoint64u (2014/03/07)
8    o verification/MLAdjust:
9      - rename secondary test suffix:
10         1.leith  -> A4FlxF  + switch to flux-form & add side-drag
11         0.leithD -> AhFlxF  + switch to flux-form
12         0.smag   -> AhVrDv  (use Vorticity-Div. visc form) + add side-drag
13         0.leith  -> AhStTn  (use Strain-Tension visc form) + add side-drag
14    o pkg/mom_vecinv:
15      - remove unused arguments from S/R MOM_VI_HDISSIP & MOM_HDISSIP (as it used
16        to be before mom_calc_visc.F)
17      - skip the call to MOM_CALC_TENSION & MOM_CALC_STRAIN if not needed.
18      - add 2nd copy of vort3 & strain that knows about lateral BC (free/no slip):
19        this is simpler for the adjoint and for diagnostics.
20    o model/src + pkg/momentum:
21      - add input files for  2-D additional Western and Southern cell-edge wall
22         (e.g., to add "thin-wall" where it is =1).
23      - fix sideDrag option for thin-walls with Non-Lin Free-Surf
24        using 2nd hFacZ that is computed from initial (fix domain) hFac
25      - known limitations of thin wall implementation: not yet coded for sigma
26        coords; not working with CD-scheme neither.
27    o pkg/seaice:
28      - rename recently introduced parameters from (wrong name) AB to
29        BDF (backward difference time discretisation)
30      - retire runtime parameters SEAICEuseAB2, SEAICE_abEps
31    o tools/adjoint_options:
32      - remove setting of "OPENAD=true" (now set by command line "genmake2 -oad")
33    
34    checkpoint64t (2014/02/01)
35    o pkg/thsice
36      - corrected store directive fixes thsice adjoint gradient checks
37    o genmake2 & testreport:
38      - add genmake2 option "-oad" to generate a Makefile for OpenAD built and
39        in this case, use tools/adjoint_options/adjoint_oad as default AD optfile.
40        Update testreport accordingly. No need to set "export OPENAD=true"
41        in adjoint_options/adjoint_oad anymore (will be removed later).
42    o pkg/shelfice:
43      - put T & S shelfice forcing into model surfaceForcing_T,_S (for now,
44        only if SHELFICEboundaryLayer=F); Change model/src/external_forcing.F
45        so that surface forcing applies to k=kSurf if using pkg/shelfice.
46    o pkg/ctrl, pkg/grdchk, pkg/ecco:
47      - Changes to make GENARR more modular (i.e. invisible if not used)
48    o model/src/temp_integrate.F and salt_integrate.F
49      - re-include store directives that were removed on Dec 27th.
50    o model/src/external_forcing_surf.F
51      - add storage directives for EmPmR and PmEpR to avoid recomputation of
52        seaice_model in the adjoint that is problematic when seaice_model is
53        turned off in the adjoint. The resolved issue dated back to July when
54        EXTERNAL_FORCING_SURF call was moved.
55        Update global_ocean.cs32x15/*/output_adm.seaice_dynmix.txt accordingly.
56    o pkg/exf/exf_check.F
57      - fix a small bug again (originally found by Wentao Liu, now found again)
58      - streamline error output
59    o pkg/streamice and aim_v23:
60      - replace a few "_EXCH_XY_RL (" with "_EXCH_XY_RL(", so that
61        Apple's /usr/bin/cpp knows what to do:
62        Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)
63        Target: x86_64-apple-darwin13.0.0
64    
65    checkpoint64s (2014/01/05)
66    o tools/adjoint_options:
67      - switch to fastopt.net TAF server (instead of default fastopt.de) for
68        AD optfiles adjoint_diva & adjoint_f95 (similar to adjoint_default).
69    o model/src:
70      - remove some unnecessary TAF storage directives in forward_step.F and
71        in dynamics.F (note: not always removed by TAF, e.g., double storage
72        of kappaRU,kappaRV in former version of dynamics.F).
73    o model/src & pkg/ptracers:
74      - call directly GAD_IMPLICIT_R & IMPLDIFF + DWNSLP_APPLY from temp_integrate.F
75        salt_integrate.F and ptracers_integrate.F (instead of from thermodynamics.F)
76        and remove ptracers_dwnslp_apply.F & ptracers_implicit.F
77      - call MATRIX_STORE_TENDENCY_EXP for each tracer (in ptracers_integrate.F)
78      - add fZon & fMer as output argument of S/R GAD_CALC_RHS.
79      - update TAF AD-output of experiments global_ocean.90x40x15 (13 for AD-grad).
80    o useSingleCpuInput separates single-CPU input from single-CPU output;
81        for now only implemented for in exf_interp_read.F
82    o verification/advect_xy:
83      - fix missing EXCH call in local version of ini_salt.F and update output.
84    o momentum diagnostics:
85      - fix which deltaT is used in Total-Tendency diagnostics.
86      - fix typo in diagnostics for momentum tendency from AB.
87    o pkg/seaice/seaice_lsr.F: fix an initialisation bug for the
88        SEAICE_VECTORIZE_LSR_ZEBRA option that lead to NaNs on a NEC-SX8
89    
90    checkpoint64r (2013/12/08)
91    o verification/*/results:
92      - Update reference output of experiments that were passing with just 13 digits
93         (make it easier to detect future changes in results)
94    o model/src & pkg/ptracers:
95      - move calls to GAD_ADVECTION (Multi-Dim advection) from thermodynamics.F to
96        inside temp_integrate.F and salt_integrate.F and from ptracers_advection.F
97        to inside ptracers_integrate.F ; remove ptracers_advection.F
98    o coupling interface pkgs:
99        [atm_compon_interf, ocn_compon_interf & atm_ocn_coupler]
100      - change the config check to test the agreement of Ocean Depth
101        with ATM land/sea mask (instead of ATM orography);
102      - send to coupler the number of coupler time-steps to do for this run:
103        this allows to check for consistency and don't need anymore to be
104        specified in parameter file "data";
105      in coupler:
106      - check consistency of RunOff map versus Ocean Depth and ATM land/sea mask.
107      - improve report to log-file of config setting (pass log-file unit to few S/R)
108    o pkg/compon_communic:
109      - add coupling send/receive for non-tiled integer vector;
110      - add S/R to check and stop if any proc has an error (similar to
111        eesupp/src/stop_if_error.F but single thread and across Comm_World).
112    o pkg/exch2:
113      - in exch2*_get_rx[1,2]: use new list "W2_tileIndex" to replace search
114        through list of all tiles my proc owns.
115    o model/src:
116      - AUTODIFF only: in calc_adv_flow.F, recompute rTransKp (instead of copying
117        from rTrans) to simplify dependencies (no need to store rTrans anymore in
118        calling S/R); this affects AD results at machine truncation level:
119        update AD-output (TAF) of experiments: 1D_ocean_ice_column,
120        bottom_ctrl_5x5 & obcs_ctrl (12 digits for AD grad, same FWD grad).
121    o tools/build_options:
122      - simplify Warnings options (-ieee & -devel cases) in linux_amd64_gfortran
123    o coupling interface pkgs:
124        [compon_communic, atm_compon_interf & ocn_compon_interf]
125      - move declaration of local array "ibuf" out of header file "CPLR_SIG.h"
126        to each S/R that needs it; remove un-used variables.
127      - change component tile registration (cpl_register.F in both compon_interf
128        and mitcomponent_tile_register.F) to pass the full list of tiles
129        information (including bi,bj) in 1 vector (instead of in a bi,bj matrix).
130      - with pkg/exch2: adopt the same convention used for I/O to define mapping
131        towards coupler global array (unless W2_useE2ioLayOut=F):
132         a) can now use different tiling between atm & ocn comp.
133         b) no needs to modify the run-Off map when changing tiling (was needed
134            even if using the same tiling between atm & ocn).
135         c) will allow to run with blank-tiles in 1 component (e.g., for ocean
136            full land tiles); not yet tested.
137      - check for valid mapping from comp. tile to coupler global array
138      - improve report of tile registration results to log file.
139    o pkg/exch2:
140      - in eesupp/src/eeboot.F: move call to W2_EEBOOT before Coupler
141        tile-registration (CPL_REGISTER);
142      - activate (un-comment) definition and setting of "W2_tileIndex" list to
143        store the local bi,bj indices of each tile;
144      - also print bi,bj in local report to log file;
145      - fix pkg/debug/debug_cs_corner_uv.F for the case nSy > 1 (left from
146        Jun 2009 modif of pkg/exch2).
147    o testing on baudelaire:
148      - run 2 tests at a time: no significant slow down (since enough cpu) and
149        get the full set of test done earlier
150      - switch the ifort test to "-devel" ; run the OpenAD test everyday.
151    o model/src/thermodynamics.F and routines called from it:
152      - pkg/gmredi: gmredi_residual_flow.F (replacing gmredi_calc_uvflow.F &
153        gmredi_calc_wflow.F) to update eulerian velocity (input) into residual
154        velocity (outp) by adding bolus velocity.
155      - model/src: calc_adv_flow.F (replacing calc_common_factors.F) to compute
156        mass transport from velocity + lateral grid cell area
157      - rename calc_gt.F to temp_integrate.F (includes call to TIMESTEP_TRACER)
158      - rename calc_gs.F to salt_integrate.F (includes call to TIMESTEP_TRACER)
159     in thermodynamics.F
160      - remove k from thermodynamics.F and move it to temp_integrate.F
161        salt_integrate.F and ptracers_integrate.F (now done inside the tracer
162        loop).
163      - compute locally (in thermodynamics.F) 3-D velocity field that is used to
164        advect tracers; pass it as argument to GAD_ADVECTION, GAD_SOM_ADVECT,
165        PTRACERS_ADVECTION, TEMP_INTEGRATE, SALT_INTEGRATE, PTRACERS_INTEGRATE,
166        GAD_IMPLICIT_R and PTRACERS_IMPLICIT
167      - update AD-output (TAF & OAD) of experiments: 1D_ocean_ice_column,
168        global_ocean.90x40x15, tutorial_global_oce_biogeo and
169        tutorial_tracer_adjsens (+ TLM output).
170    o tools/OAD_support and (verification/*/) code_oad:
171      - OAD_support/cb2mGetModules.csh: add PACKAGES_CONFIG.h in header file to
172        module conversion ; remove unneeded CPP_EEOPTIONS.h.
173      - code_oad/CPP_OPTIONS.h: remove PACKAGES_CONFIG.h and use a more standard
174        version (closer to model/inc/CPP_OPTIONS.h).
175    o model/src:
176      - remove parameter "useOldFreezing" from PARAMS.h and push it to the
177        retired list of parameters (routine FREEZE has been replace by surface
178        freezing (10.yrs ago) and by pkg/frazil (interior freezing).
179    o pkg/gmredi:
180      - add option (GM_CALC_TRANSP_FROM_VEL) to compute transport directly from
181        velocity (same scheme but affects machine truncation) for GM_AdvForm.
182      - update output of FWD experiments: front_relax.bvp,
183        global_ocean.90x40x15.dwnslp, global_ocean.cs32x15 and ideal_2D_oce.
184    
185    checkpoint64q (2013/11/17)
186    o verification:
187      - generate new output on baudelaire (gfortran, -ieee) for OpenAD experiments
188        tutorial_global_oce_biogeo and global_ocean.90x40x15.
189      - generate new output (growth & melt) for seaice_itd experiment after
190        updating the input pickup_seaice files (previously wrong).
191    o pkg/cost:
192      - define a "final cost function" for each tile, and use GLOBAL_SUM_TILE_RL
193        (instead of _GLOBAL_SUM_RL) to get the final cost from all procs & threads:
194        o this fixes global-sum value if multi-threads (since GLOBAL_SUM_RL
195          cannot be applied to var in common block).
196        o allows to get results independent of tile-per-proc setting (if using
197          slower GLOBAL_SUM_SEND_RECV option).
198      - update accordingly: seaice_cost_final.F, shelfice_cost_final.F,
199        thsice_cost_final.F and ecco_cost_final.F (this one affects lab_sea
200        forward gradients: update output).
201      - update */code_oad/externalDummies.F by adding dummy GLOBAL_SUM_TILE_RL
202        S/R and, for most exp., also comment out GLOBAL_SUM_R8.
203    o pkg/mom_common:
204      - move to pkg/mom_common and model/src (previously in tutorial_deep_convection
205        code) 2nd version of isotropic 3-D Smagorinsky code interface: strain and
206        viscosity are locally declared in dynmics.F and pass as argument to CALC_GW;
207        ensure that all field value that are used are set.
208    o tutorial_deep_convection (smag3d):
209      - add missing scaling in mom_calc_smag_3d.F;
210      - set smag3D_coeff in input.smag3d such that results do not change.
211    o pkg/dic:
212      - change dic_cost.F to compute cost on each tile first and then apply
213        GLOBAL_SUM_TILE_RL: this affects forward gradient of AD experiments
214        tutorial_dic_adjoffline & tutorial_global_oce_biogeo; update output.
215      - remove kLev argument and use GLOBAL_SUM_TILE_RL in tracer_meanarea.
216    o eesupp/src & pkg/mdsio:
217      - remove gather/scatter_vector.F (from eesupp) and mdsio_read/writevector.F
218        (from pkg/mdsio) since they are no longer used for tape IO.
219      - move simple C subroutine "setdir.c" from pkg/compon_communic to eesupp/src
220        (+ keep a copy in pkg/atm_ocn_coupler).
221    o verification/isomip:
222      - split domain in 8 squared tiles (instead of just 2) for FWD, AD & OAD tests.
223    o tools/build_options:
224      - optfile linux_amd64_ifort11, fast (no ieee) case:
225        to get a working restart for all experiments, add "-fp-model source"
226        to FOPTIM (also remove "-opt-streaming-stores auto" <- this is the default).
227    
228    checkpoint64p (2013/10/20)
229    o pkg/autodiff:
230      - adread_adwrite.F: when type and length do not match ALLOW_AUTODIFF_WHTAPEIO
231        criteria, return to simple (default) tape IO format.
232    o pkg/mdsio (+ eesupp/src):
233      - rewrite/simplify tape-IO S/R (new S/R MDS_READ/WRITE_TAPE replace
234        previous MDSREAD/WRITEVECTOR) with 2 array argument from each type (R4/R8);
235      - fix globalFile and singleCpuIO options using simpler global mapping.
236      - new pairs of scatter/gather vector S/R (one for each type, generated from
237        template) corresponding to simpler global mapping.
238      - adread_write.F: switch to new S/R (but leave old calls commented) and write
239        to globalFile when parameter globalFiles is set to True.
240      - switch on useSingleCpuIO in AD experiments: global_ocean.90x40x15 & isomip.
241    o pkg/autodiff:
242      - adread_adwrite.F: add a hack for RS arrays (when RS=real*4);
243        with ALLOW_AUTODIFF_WHTAPEIO defined, since corresponding (real*4) is
244        missing, just add a STOP if array type do not match.
245    o pkg/exf:
246      - to allow to use seaice-fraction from pkg/exf in other pkgs than pkg/seaice:
247         rename CPP option EXF_ALLOW_SEAICE_RELAX to EXF_SEAICE_FRACTION
248         and rename array obsSIce to exf_iceFraction.
249    o tutorial_deep_convection:
250      - add 1rst version of isotropic 3-D Smagorinsky code (from Louis-Philippe),
251        for now all in this exp. code dir.
252      - add secondary test using Smag-3D viscosity (keep very low backgroud visc for
253        testing) and flux-limter advection scheme for Temp. (no explicit diffusion).
254    o eesupp/src:
255      - added SINGLE_DISK_IO option because reading of parameter files on
256        very large number of processors did not work with existing set-up
257    
258    checkpoint64o (2013/09/25)
259    o pkg/atm_phys & atm_compon_interf:
260      - allows for coupling of gray-atmosphere (atm_phys) with ocean.
261    o tools/build_options:
262      - switch from "-fPIC" to "-mcmodel=medium" in optfiles: linux_amd64_gfortran
263        & linux_amd64_ifort11 and in linux_amd64_g77 & linux_amd64_open64 also
264        remove CPP setting (was identical to genmake2 default).
265    o pkg/gmredi & model/src: Some updating and work done on the residual model.
266      - created new file model/src/calc_eddy_stress.F to calculate the eddy stress.
267      - fixed up the calculation of the eddy stress and how it is added to the
268        external forcing via taueddy_external_forcing.F
269      - at the moment, it is very experimental and only works with the variable eddy
270        diffusivity calculated in gmredi_k3d.F
271    o pkg/seaice/seaice_check.F: add a check to catch the case of specifying
272        lw/swfluxfile instead of lw/swdownfile in data.exf together with pkg/seaice
273    o testreport (& tools/do_tst_2+2):
274      - for MPI test, set default COMMAND to 'mpirun -v -np TR_NPROC ./{executable}'
275    o tools/build_options: linux_amd64_gfortran & linux_amd64_ifort11:
276      - remove CPP='cpp -traditional -P' (this is genmake2 default)
277      - add switch (for big setups) to use 'medium' memory-model (but leave it
278        commented out for now). Note: needed with FC 19 to compile big setups.
279    o pkg/atm_compon_interf:
280      - regroup per field origin (model & pkgs) the coupling storage routines
281         (which accumalate in time each coupling field)
282      - move bi,bj loops inside atm_store_my_data.F and store also wind-stress;
283        update accordingly + simplify aim_do_physics.F
284    
285    checkpoint64n (2013/08/26)
286    o pkg/bbl:
287      - update formulation to reduce dispersion of tracer properties in bbl
288      - replaced horizontal and vertical transport parameters with velocities
289      - changes results for verification/global_with_exf.yearly
290    o verification/halfpipe_streamice:
291      - change to matrix construction; update both Fwd & AD output.
292    o verification/tutorial_tracer_adjsens:
293      - OpenAD test: switch to vector-invariant momentum since fluxform with
294        rStar causes problems with OpenAD; update output.
295    o tools:
296      - genmake2: define a common prefix for all temp-file names ; move them
297        to local /tmp disk (but would be easy to move them back);
298      - xmakedepend: apply the same switch for temp-files.
299    o pkg/offline:
300      - changes for use with rStar (NLFS): assume that we continue to provide
301        UVELMASS/hFacW_ini & VVELMASS/hFacS_ini (hFacWi,S_ini as written in grid
302        output files) and apply r* scaling at each time-step (function of the time
303        varying Eta field); use normal pickup files (needed for restart with NLFS).
304    o adjoint with OpenAD:
305      - move OpenAD-specific files from verification/OpenAD/code_oad_all to a new
306        package openad.  This package has to be compiled for all runs with OpenAD
307        instead of specifying code_oad_all as a modification directory.
308      - link the fortran templates from tools/OAD_support to the build directory
309        for preprocessing to avoid conflicts between different setups compiled
310        simultaneously and simplify cleanup.
311    o pkg/exf:
312      - in exf_getforcing.F: comment out most of the EXCH calls (fields used by
313        main model or other pkgs are exchanged in EXF_MAPFIELDS).
314    o model/src:
315      - do_stagger_fields_exchanges.F: skip EXCH calls when using pkg/offline
316        (similar to do_fields_blocking_exchanges.F).
317    o tools/genmake2:
318      - remove TAF output src code just before calling staf (when not doing a fresh
319        built, will stop if things go wrong with staf).
320      - fix target "adobj" (left from TAF version-2 transition)
321    o pkg/diagnostics:
322      - add a parameter to track the status of pkg/diagnostics activation;
323        this replace/extend the use of logical param "settingDiags" (to check
324        when adding diag to the list) to also check any DIAGNOSTICS_[]FILL* call.
325        New S/R to print error message and stop when pkgStatus is not right.
326      - to try: add a warning when "data.diagnostics" exist but useDiagnostics=F.
327    
328    checkpoint64m (2013/08/13)
329    o model/inc:
330      - move FCORI_MACROS.h from PARAMS(_MACROS).h to GRID_MACROS.h (left from
331        8 yrs ago modif when Coriolis arrays were moved from PARAMS.h to GRID.h)
332    o pkg/kpp & aim_v23:
333      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
334    o pkg/seaice:
335      - restore (last time on 2011/12/24) ability to compile pkg/seaice with
336        undefined pkg/exf ALLOW_ATM_TEMP or ALLOW_RUNOFF CPP-options.
337      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
338    o eesupp/src:
339      - fix check for overlap-size argument (myOLn.GT.MAX_OLY_EXCH)
340        in exch1_rx[_ad].template (thanks to Francois Lefeuvre report).
341    o switch to TAF version-2:
342      - add flow directives to "freeze" naming convention for ad-routines that
343        are used in I/O routines of adjoint state and associated common blocks
344        that are used in adcommon.h (backward compatible with version-1)
345      - update all ad-optfiles (in tools/adjoint_options + few local to some
346        verification exp) to switch to latest TAF version (currently 2.5.5);
347        merge "*_mpi" adoptfiles into the corresponding non-mpi (but commented
348        out except for diva).
349      - the major change with TAF version-2 is that both the differentiated
350        routines and the forward routines (new) are returned as part of the TAF
351        output source code. Update genmake2 accordingly.
352      - new output for AD experiment tutorial_global_oce_biogeo (better AD gradient
353        with version-2 when compared to TLM or FWD gradient); other experiments
354        output show minor changes (machine truncation level); update the few AD &
355        TLM output with 12 matching digits only (some prior to version-2 switch).
356    
357    checkpoint64l (2013/08/05)
358    o model/src:
359      - in dynamics.F, skip the call to CALC_VISCOSITY if momViscosity=F
360      - main_do_loop.F: no longer includes additional (AUTODIFF) header files
361        when using TAF but only if using OpenAD.
362    o pkg/mom_common+fluxform+vecinv:
363      - always set horiz. viscosity arrays to background value before calling
364        MOM_CALC_VISC (in MOM_FLUXFORM & MOM_VECINV) and call S/R MOM_CALC_VISC
365        only when using variable horiz. viscosity (useVariableVisc=T);
366      - simplify mom_vecinv.F (only 1 block for momViscosity).
367    o pkg/mom_common: variable horiz. viscosity in NH code
368      - move horiz-viscosity 3-D arrays viscAh_W & viscA4_W (used in calc_gw.F)
369        from model/inc/NH_VARS.h to pkg/mom_common/MOM_VISC.h
370      - store in common block (in MOM_VISC.h) logical parameters: useHarmonicVisc,
371        useBiharmonicVisc & useVariableVisc.
372      - fix old bug (already in 1rst implementation of variable horizontal viscosity
373        in calc_gw.F, version 1.27, 2006/06/20):
374        horizontal bi-harmonic viscosity in gW was missing when wiscA4W=0
375        even if variable bi-harmonic viscosity (e.g., viscA4Grid) was non-zero.
376      - change background horiz viscosity in vertical momentum (gW) to always be
377        viscAhW,viscA4W (instead of switching to viscAhD, viscA4D when using
378        any type of variable viscosity, e.g., viscAh/4Grid)
379      - change default value of viscAhW,viscA4W to viscAhD,viscA4D (instead of
380        viscAh,viscA4) which default to viscAh,viscA4 :  this avoid missing
381        horiz. viscosity in W eq when just setting viscAhD/Z,viscA4D/Z (since
382        default viscAh,viscA4 is zero).
383    o model/src:
384      - extend length of drC & recip_drC from Nr to Nr+1.
385    o Divided Adjoint (DIVA) with MPI:
386      - genmake2: do not create local ./mpi_headers dir when no file to copy into.
387      - remove option ALLOW_DIVIDED_ADJOINT_MPI (replaced by ALLOW_DIVIDED_ADJOINT
388        and ALLOW_USE_MPI) from model/src code and from ECCO_CPPOPTIONS.h.
389    
390    checkpoint64k (2013/07/23)
391    o tools/OAD_support:
392      - avoid the need for file "oadtempflile" in insertTemplateDir.bash
393        and remove it from genmake2.
394    o tools/build_options:
395      - remove MPI_HEADER_FILES_INC setting (no longer used) and comment out
396        MPI_HEADER_FILES list (let genmake2 find the missing headers)
397    o verification/halfpipe_streamice:
398      - change to driving stress formulation; update both Fwd & AD output.
399    o tools/genmake2 and Divided Adjoint with MPI:
400      - remove default setting of MPIINCLUDEDIR from $MPIHOME (always been broken);
401      - only create local ./mpi_headers dir if using MPI and MPIINCLUDEDIR is set;
402      - add new variable (LOCAL_MPI_HEADERS, replace MPI_HEADER_FILES_INC) in
403        Makefile, which is set by genmake2, and check which mpi-headers are needed.
404        Note: need to update adjoint_options/adjoint_diva_mpi accordingly.
405      - update target "CLEAN" (to also remove ./mpi_headers/ dir).
406    o testreport:
407      - changes for Divided Adjoint Run: when file "run_ADM_DIVA" is present,
408        perform additional runs (number of additional runs is "add_DIVA_runs" taken
409        from file run_ADM_DIVA ; should match "nchklev_3" in file "code_ad/tamc.h").
410    o verification/lab_sea (AD test):
411      - change to test Divided Adjoint Run in this set-up (both standard AD test
412        and 2 secondary AD test: noseaice + noseaicedyn); drop the evp AD test.
413    o pkg atm_ & ocn_compon_interf:
414      - remove cpl_earlyExpImpCall=F option (was mainly a hack added for the old
415        staggerTimeStep implementation) and disable (retired) corresponding
416        parameter.
417    o pkg/offline:
418      - comment out unused field-array: ICEM, ConvectCount, hflx[01], icem[01];
419      - add S/R OFFLINE_CHECK to print offline parameter summary
420        and stop if loading a file that is not used;
421      - enable to calculate GMRedi tensor, KPP mixing and convective index
422        when the corresponding file(s) is/are not specified (but pkg is used).
423      - comment out resetting of monitorFreq (to endTime) since it still useful
424        for monitoring CFL numbers and checking offline fields.
425    o OpenAD:
426      - do not define OAD_DEBUG (in tools/adjoint_options/adjoint_oad) to get
427        smaller standard output) and generate new (smaller) output (on baudelaire
428        using gfortran with -ieee) for exp. tutorial_tracer_adjsens
429    o model/src:
430      - call EXTERNAL_FORCING_SURF outside bi,bj loops (in do_oceanic_phys.F),
431        (where external_forcing_adjust was called) and change list of arguments;
432      - merge external_forcing_adjust.F into external_forcing_surf.F
433      - put surface relaxation of SST & SSS in new S/R (forcing_surf_relax.F)
434        which also contains balancing surface relaxation (ALLOW_BALANCE_RELAX,
435        previously in file "balance_relax.F", now removed); remove corresponding
436        arrays in FFIELDS.h.
437      - EXTERNAL_FORCING_SURF is now called when using pkg/offline; implement
438        a hack for getting back surfaceForcingS (loaded from file) when using
439        ALLOW_OLD_VIRTUALFLUX (pkg/dic, in DIC_OPTIONS.h) in offline set-up.
440      - update output of AD test experiment global_ocean.cs32x15.seaice_dynmix
441        (was getting only 11 digits for AD-grad, due to different truncation
442         error in AD code).
443    
444    checkpoint64j (2013/07/04)
445    o pkg/offline:
446      - to enable the use of other features with pkg offline (e.g., obcs),
447        also call S/R DO_OCEANIC_PHYS in offline run - more modifs to come.
448      - comment out "allowFreezing" (now active) in 2 offline testing exp.
449    o pkg/exf ALLOW_RUNOFTEMP
450      - fix sign and make compatible with temp_EvPrRn .NE. UNSET_RL
451      - ahdded RUNOFTEMP test to verification/global_ocean.cs32x15/input.seaice
452      - changes verification/global_ocean.cs32x15/results/output.seaice.txt
453    o pkg/atm_phys:
454      - allows to add some damping on uVel,vVel (strength only function of k).
455    o verification, ad-tests:
456      - reduce length of the simulation for AD test: global_ocean.cs32x15.seaice,
457        global_ocean_ebm and offline_exf_seaice.thsice.
458    o verification/halfpipe_streamice:
459      - found a bug in s/r pkg/streamice/streamice_advect_thickness which caused
460        flux input boundary conditions to be ignored; a fix for this bug changed
461        verification results for forward test.
462      - add adjoint test.
463    o pkg/ptracers:
464      - allow to restart without SOM pickup (resetting SOM to zero).
465    o pkg/gmredi:
466      - New parameterisation for the calculation of K and (GM_PsiX,GM_PsiY) added.
467      - It uses mixing length theory and suppression by steering level effects to
468        calculate a diffusivity used in the Redi tensor (see Bates et al., submitted
469        to JPO, for more details).
470      - It also uses the diffusivity to calculate an eddy induced streamfunction
471        based on a PV closure (rather than a buoyancy closure as in GM).
472      - New files added to pkg/gmredi:
473        gmredi_k3d.F calculates the diffusivity for the Redi tensor and the eddy
474          induced overturning streamfunction (called from gmredi_calc_tensor)
475        gmredi_calc_eigs.F calculates the eigenvalues and eigenvectors required
476          for use in gmredi_k3d
477        gmredi_calc_urms.F calculates the the rms eddy velocity used to calculate
478          the eddy diffusivity
479    
480    checkpoint64i (2013/06/18)
481    o pkg/cheapaml:
482      - take src files from MITgcm_contrib/verification_other/offline_cheapaml/code
483        that enable the use of seaice (pkg/thsice thermo & pkg/seaice dynamics)
484        with pkg/cheapaml.
485    o utils/python: add subpackage for cubed sphere function, first example is
486        simple cs.pcol to plot 2D fields on a map
487    o pkg/streamice:
488      - This is a new package in MITgcm, which solves dynamic equations for ice
489         sheets and ice streams
490      - At the moment it is independent of atmosphere/ocean dynamics, or any
491        other physical packages in MITgcm, even ShelfIce (although it is anticipat-
492        ed that this will change)
493      - There is a new verification exercise that tests it, halfpipe_streamice,
494        evolves a 40x80 km ice stream/ice shelf (at coarse resolution) in a
495        rectangular embayment
496      - halfpipe_streamice is forward-only for now, will have TAF test soon
497      - for questions, email dgoldber@mit.edu
498    o pkg/thsice:
499      - fix filling of snow-precip diagnostic (SIsnwPrc) (left from the removing
500        of snowPrc from common bloc, on May 2nd, thsice_step_fwd.F revision 1.40);
501      - remove diagnostics 'SI_FrcFx' ( now identical to 'SI_Fract' with new
502         call sequence: ice-Thermo(thsice),ice-Dyn,ice-Advect );
503      - allow precip from pkg/cheapaml to make snow over seaice.
504    o pkg/cfc:
505      - move in separated header file (CFC_ATMOS.h) time-serie arrays of Atmos CFC
506      - remove atmos CFC 2-D arrays from common bloc (now local variables)
507      - change some hard-coded constant to run time parameter for reading and
508        and interpolating atmospheric CFC ; keep same default as previously.
509      - more flexible reading of Atmos CFC (number of records no longer hard-coded)
510      - put arguments in standard order: myTime, myIter, myThid
511      - use standard S/R GET_PERIODIC_INTERVAL for time interpolation of
512        atmospheric CFC ; fix for the case myIter < PTRACERS_iter0.
513      - fix calculation of surf tendencys for partial-cell and/or Non-Lin Free-Surf
514      - new routine to print summary of CFC params and check for consistency.
515    o pkg/seaice: add uice/vice to the parameter list of s/r seaice_advdiff,
516      similar to thsice_advdiff.
517      Note that for the B-grid case the routine parameters uc/vc are overwritten.
518    o pkg/cfc:
519      - change time interpolation for atmospheric CFC-11 (now same as for CFC-12);
520        update output (CFC-11) of experiment cfc_example and tutorial_cfc_offline.
521      - fix interpolation of atmphspheric CFC between Sorthern and Northern
522        hemisphere value.
523    o pkg/seaice:
524      - allow to use seaice dynamics without pkg/exf (e.g., using pkg/cheapaml)
525    o pkg/seaice: add Adams-Bashforth2 time discretization for ice dynamics;
526                  so far only for JFNK-solver, turn on with SEAICEuseAB2 = .TRUE.
527      - requires an additional time level that is stored in the pickup
528      - you can start with AB2 from a pickup without this time level with
529        pickupStrictlyMatch = .false.
530    
531    checkpoint64h (2013/05/26)
532    o pkg/cheapaml:
533      - replace one ()**.5 with SQRT + use temp var "cdu = tau/Du" (coare3_flux);
534        affect machine truncation (but exp cheapAML_box still pass with 13 digits).
535      - consistent treatment of uWind,vWind location: assume everywhere in
536        pkg/cheapaml that they are on C-grid (@ uVel,vVel location)
537        (Note: was already the case for Tair,Qair advection);
538        add option (INCONSISTENT_WIND_LOCATION) to recover old results.
539      - compute diabatic forcing only in the interior (excluding overlap regions)
540      - fill in array "Qsw" (for short-wave heating);
541      - add diagnostic for precip ; fill-in diagnostics for cheapAML state vars
542        before any update (consistent with MITgcm state var diagnostics);
543      - cheapaml_fields_load.F & cheapaml_init_varia.F : only fill outer edges if
544        non periodic ; + adjusted for uWind,vWind (C-grid).
545    o pkg/seaice:
546      - remove dependence of pkg/seaice versus pkg/exf (file: pkg/pkg_depend) and
547        add explicitly pkg/exf in experiments that currently use pkg/seaice.
548      - allows to compile pkg/seaice without pkg/exf.
549    o tools/OAD_support:
550      - use a local copy (ourRWCPinBd) to ensure index ourRWCP stays within bounds
551        of array "ourStepOf" in function rvNextAction (revolve.F90).
552    o pkg/aim_compon_interf renamed to pkg/atm_compon_interf
553      - change pkg name (to be used with other atmospheric physics pkg)
554        but by-pass CVS when making the new pkg so that we keep the CVS history.
555    o pkg/offline:
556      - call OFFLINE_FIELDS_LOAD from pkg/offline/offline_init_varia.F
557        (previously called from pkg/dic_surfforcing_init.F)
558    o model/src:
559      - re-order sequence of calls within packages_init_variables.F, using
560        standard order, except for:
561         DIAGNOSTICS_INIT_VARIA and OFFLINE_INIT_VARIA (called @ the top),
562         CTRL_MAP_INI and OBCS_INIT_VARIABLES (called @ the bottom)
563    o new pkg: atm_phys
564      - add entry point and source code (previously in contrib
565          verification_other/atm_gray/code_gray/) for new pkg "atm_phys"
566        (atmospheric physics pkg from P. O'Gorman and T. Schneider, JCl, 2008).
567      - re-order sequence of calls within packages_readparms.F,
568         packages_init_fixed.F and packages_write_pickup.F
569        (but skip packages_init_variables.F because of TAF issues).
570      - update contrib/*/atm_gray/ experiment.
571    o pkg/seaice (ITD code):
572      - simplify and fix the writing of pickup-files for ITD case
573    o pkg/seaice (ITD code):
574      - introduce floe size dependent lateral melt for ITD case;
575      - cleaning (avoid division by zero, change to f77 syntax, remove tabs)
576      - update seaice_itd experiment main output.
577    o pkg/thsice:
578      - remove snowPrc from common block THSICE_FLUX, in THSICE_VARS.h and
579        declared it locally (without bi,bj) in thsice_main.F & aim_do_physics.F;
580        changed accordingly pkg/atm2d.
581    
582    checkpoint64g (2013/05/01)
583    o pkg/exf ALLOW_RUNOFTEMP
584      - if defined,  river and glacier runoff temperature can be read-in from
585        runoftempfile; runoftempfile needs to have same format as runofffile
586    o pkg/thsice (& pkg/bulk_force):
587      - In case Energy-Reference-Level (ERL) is used (temp_EvPrRn=0), account
588        for energy content of Precip + RunOff & Evap (like with pkg/exf).
589      - change computation domain to always be the interior (without overlap).
590      - fix bug (wrong overlap) when using EXF and stressReduction > 0.
591    o verification/tutorial_global_oce_biogeo:
592      - add preliminary OpenAD setup (still has problems)
593    o pkg/seaice:
594      - turn some parameters for choosing the convergence criterion of
595        the inexact Newton method (JFNK) into runtime parameters for convenience
596      - clean up seaice_calc_viscosities.F: remove/retire two options for
597        SEAICetaZmethod (1,2), introduce area weighting for method 3; this changes
598        the results of lab_sea/input because a division has been replaced by
599        a multiplication with the reciprocal (sumNorm)
600      - modify offline_exf_seaice/input.dyn_jfnk/data.seaice to improve
601        convergence of solver (changes results, of course), and to test some
602        new features
603    o model/src:
604      - remove unused (since Aug 2006) S/R SET_WRITE_GLOBAL_PICKUP and its call.
605      - remove unused forcing field "dQdT" and associated parameter "dQdTFile".
606      - move forcing adjustment (balancing surface forcing) in specific S/R
607        where might also be applied exchanges (if needed) to forcing arrays.
608    o pkg/shelfice:
609      - allow to specify the Ice-Shelf mass per unit area (instead of
610        shelficeLoadAnomaly) and do the conversion from one to the other
611      - move loading from file of shelficeLoadAnomaly from SHELFICE_INIT_VARIA
612        to SHELFICE_INIT_FIXED: (a) avoid some TAF recompution issues and
613        (b) will be loaded in time (before calling INI_PRESSURE) in case it is
614        needed in phi0surf for initial pressure calculation when useDynP_inEos_Zc
615      - update isomip experiment forward output (get machine truncation error
616        from conversion shelficeLoadAnomaly -> shelficeMass -> shelficeLoadAnomaly)
617    o verification/offline_exf_seaice:
618      revise data.seaice in input.thermo and input_ad and update results accordingly
619        HO = 0.2, SEAICE_areaLossFormula = 2,
620        SEAICE_growMeltByConv = .TRUE.,
621        SEAICE_doOpenWaterMelt = .TRUE.,
622      Improve consistency with input.thsice and fix the spurious 500m ice corners
623    o verification/global_ocean.cs32x15:
624      - set Energy Reference Level to liq. water @ 0 degC: temp_EvPrRn=0.,
625        in icedyn (thsice+seaice-dyn) test and update output.
626    o verification/offline_exf_seaice:
627      - adjust list of tested variables (with testreport) and update
628        standard test output with better slection of monitored fields.
629    o pkg/cd_code:
630      - swtich off Adams-Bashforth on the 1rst iteration. Update output of
631        experiment lab_sea.hb87
632    o tools/genmake2:
633      - change default makedepend from the system default to tools/xmakedepend:
634        When no makedepend is specified, select tools/xmakedepend it the test pass,
635        otherwise select the system default (if exist and pass the test) or
636        try to build cyrus-makedepend ; stop if none of the 3 works.
637    o pkg/exf & pkg/thsice:
638      - In case Energy-Reference-Level (ERL) is used (temp_EvPrRn=0), account
639        for energy content of Precip + RunOff & Evap. Assumes:
640       1) Rain has same temp as Air.
641       2) Snow has no heat capacity (consistent with seaice & thsice pkgs)
642       3) Run-Off comes at the temp of surface water (with same Cp)
643       4) Evap over ocean is released to the Atmos @ surf-temp (=SST); should be
644        put directly into Latent Heat flux & should use water-vapor heat capacity.
645       5) Evap over snow/seaice (pkg/thsice) assumes constant Lf+Lv (consistent
646        with snow having no Cp) => water vapor is released to Atmos @ 0^oC (=ERL).
647    o pkg/seaice: simplify the use of CPP flags in JFNK-related files
648        (compile when SEAICE_ALLOW_JFNK is defined)
649    o pkg/thsice:
650      - fix oceanic flux diagnostics & timeave (left from new sequence of calls
651        implementation): move THSICE_AVE call after the advection (called directly
652        from thsice_do_advect.F).
653    o verification/global_ocean.90x40x15 and OpenAD:
654      New experiment for OpenAD is identical to the one in input_ad except that
655        multiDimAdvection=.FALSE.,
656      There is still an issue with this.
657    o pkg/thsice:
658      - account for ice velocity (ocean relative velocity) in turbulent heat flux
659        at the base of the ice; update output of global_ocean.cs32x15 (icedyn)
660        and offline_exf_seaice (main test).
661    
662    checkpoint64f (2013/03/31)
663    o verification/OpenAD:
664      - new (smaller, without OAD_DEBUG) output_oadm.txt generated using gfortran.
665    o verification/isomip, pkg/shelfice and OpenAD:
666      - add OpenAD setup to this exp and make shelfice package work with OpenAD
667    o verification/tutorial_global_oce_biogeo:
668      - update AD and TLM output after turning off ALLOW_FE (in DIC_OPTIONS.h)
669    o verification/offline_exf_seaice:
670      - replace adjoint experiment (now similar to fwd input.thermo/ setup).
671    o verification/tutorial_tracer_adjsens, pkg/ptracers and OpenAD:
672      - add OpenAD setup to this exp and make ptracers package work with OpenAD
673    o pkg/seaice/seaice_evp.F:
674       mask the asymmetric contribution of the ice-ocean stress (when
675       the turningAngle is non-zero) over open water to avoid stripes
676       in the EVP-solutions after many EVP-substeps. This does not change
677       the verification experiment (because turningAngle=0 in that experiment),
678       but will affect other EVP solutions with turningAngle.ne.0
679    o verification, AD & TLM output:
680      - new TAF version 2.3.10 (previously 2.3.8) add more parenthesis in multiple
681        additions and multiplications which affect results at machine truncation
682        level. Update few AD output (1D_ocean_ice_column, bottom_ctrl_5x5,
683        lab_sea.noseaicedyn & offline_exf_seaice) and TLM output
684        (1D_ocean_ice_column & tutorial_tracer_adjsens.som81) which had only 12
685        digits of matching.
686    o pkg/seaice:
687       modify lsr-algorithm so that it vectorizes AND converges by using a
688       "zebra" method: split vector loop into two with step size 2; this
689       solves a general convergence problem for the JFNK solver on a vector
690       computer. It has the potential to even improve convergence for
691       non-vector machines, but it does change the results so it is turned
692       off by default. To turn on define CPP-flags SEAICE_VECTORIZE_LSR and
693       SEAICE_VECTORIZE_LSR_ZEBRA in SEAICE_OPTIONS.h
694    
695    checkpoint64e (2013/03/05)
696    o pkg/ecco and several verification experiments:
697       Remove special versions of the_model_main.F, the_main_loop.F, forward_step.F
698       from ecco package, and revert to unified routine in model/src/
699       Adjust verification experiments accordingly, especially gloal_oce_llc90
700       Should conclude long-standing work by Gael to reconsile the_main_loop with
701       ECCO and will enable OpenAD's revolve loop in ECCO setup.
702    o pkg/generic_advdiff:
703      - implement compressible flow method for multi-dim advection (similar to
704        gad_som_advect.F); add new option "GAD_MULTIDIM_COMPRESSIBLE" (since
705        TAF generates many recomputations) to use it; no yet coded with implicit
706        vertical advection.
707      - change experiment advect_cs (new output) and advect_xy (same output)
708        to test compressible flow multi-dim advection.
709    o pkg/generic_advdiff:
710      - fix SOM advection for unusual cases (linear Free-Surf in r*, other
711        cases where linear Free-Surf is not @ k=1, e.g., useShelfIce)
712    o pkg/seaice:
713      - fix bug in the no-slip implementation in seaice_calc_strainrates.F, this
714        bug affects two verification experiments (lab_sea and lab_sea.hb87),
715        recover old (wrong) results by setting noSlipFac = 2. in
716        seaice_calc_strainrates.F;
717      - add another averaging method for etaZ (etaZmethod=3), a mix of 2 and 0
718      - add runtime parameter SEAICE_JFNKepsilon for that finite difference
719        gradient in the Jacobian times vector operation (s/r seaice_jacvec)
720      - fix line search in seaice_jfnk.F (s/r seaice_jfnk_update)
721  o pkg/seaice: reorganize seaice_lsr.F to be able to reuse more code:  o pkg/seaice: reorganize seaice_lsr.F to be able to reuse more code:
