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