3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    
6    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
7    o changes to permit hi-res, cubed-sphere, configuration
8      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
9      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
10      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
11        of surface winds for the cube
12      (A verification experiment, based on global_ocean.cs32x15, but with
13       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
14       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
15       complete with example surface forcing files and matlab scripts to look
16       at the output and compare it with that of global_ocean.cs32x15.)
17    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
18       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
19       to conform to the common rule.
20    o check-in the first version of the coupler + interfaces for multi-components
21       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
22       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
23       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
24       - ocean and atmos. share the same horizontal grid (no interpolation).
25       - exchanges between component and coupler is done in forward_step
26    o new verification experiment, cpl_aim+ocn:
27       coupled ocean - AIM atmosphere on cs32 grid.
28    
29    checkpoint52d_pre
30    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
31    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
32    
33    checkpoint52c_post
34    o Fixing OPTIONS files for use of exf:
35      - ALLOW_ECCO not needed
36      - ECCO_CPPOPTIONS.h should not be included from
37        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
38        as has been the case in the past
39      - All cal/exf related options are currently set in
40        single header file. Should remain so until we
41        agree on a consistent new policy.
42    o Removed all CPP options for cal package.
43      cal has no more CPP options.
44    o modified STOREs in GAD_ADVECTION
45    o corrected key comp. for passkey
46    
47    checkpoint52b_post
48    o new version: "thsice" of thermodynamic sea-ice pkg:
49     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
50     - modify fluxes but do not change theta directly;
51     - light cleaning of bulk_force pkg (still needed with thsice).
52     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
53       + output_thsice.txt to test thsice & bulk_force pkgs.
54    o put back grid & coriolis monitor output.
55    checkpoint52b_pre
56    
57    o call "do_the_model_io" at the beginning (=> dump initial state)
58    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
59    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
60      (need info on NUMBER_OF_PTRACERS)
61    o missing PTRACERS headers in some routines
62    o default tamc.h in pkg/autodiff supposed to crash
63      to ensure proper customization
64    
65    checkpoint52a_post
66    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
67      - moved surfaceTendencyTice from pkg/seaice to main code
68      - subroutine FREEZE_SURFACE now limits only surface temperature
69        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
70        => new output.txt for global_ocean.cs32x15 & global_with_exf
71      - keep the old version of FREEZE for backward compatibility;
72        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
73      - corresponding modifs for TAF directives
74    o added surface flux output variables to TIMEAVE_STATVARS
75    o time-averaged output for pkg/ptracers
76    o fix problem with ECCO-related divided adjoint
77      snapshot file was missing some ad-variables,
78      but no warning issued by TAF
79    
80    checkpoint52a_pre
81    o some bug fixes for #undef REAL4_IS_SLOW
82    
83    checkpoint52 = ecco_c52_e35
84    o after testing adjoints of checkpoint51u_post
85    
86    checkpoint51u_post
87    o this is the post-merge tag of the ecco-branch
88      (needs another clean checkout and re-testing)
89    o various natl_box_adjoint configs and results
90      but no input fields
91    o obcs adjoint not yet merged!
92    o adding ECCO global 1x1 and 2x2 degree configs
93    o updated/extended some store directives for seaice
94    o pkg/ecco now containes ecco-specific part of cost function
95    o top level routines the_main_loop, forward_step
96      supersede those in model/src/
97      previous input data.cost now in data.ecco
98      (new namelist ecco_cost_nml)
99    o in ctrl/ cleaned some cross-dependencies and updated CPP options
100    
101    checkpoint51t_post
102    o this is the pre-merge tag of the ecco-branch
103    
104    checkpoint51s_post
105    o cleanup: removed various obsolete #define-s
106    o pkg/grdchk
107      - renamed 'ph-grd 3' to 'grad-res'
108      - merged from ecco-branch
109        (remaining bug fixes for obcs gradient checks)
110      - additional high-precision output for testreport
111        (grep for 'precision_grdchk_result')
112    
113    checkpoint51r_post
114    o cleaned up or removed CPP_OPTIONS.h files
115    o updated results for some of the tests to reflect the new
116      optfiles (-ieee: -O0 instead of -O3)
117    
118    checkpoint51q_post
119    o cd_code:
120      - moved cd_scheme.F -> cd_code_scheme.F
121      - separate read_checkpoint from cd_code_ini_vars.F
122      - separated cd_code part from write_checkpoint
123      - updated AD_SOURCE, generated .flow
124      - added CD_CODE_VARS.h to the_main_loop
125      - Moving cd_code specific store dir.s to pkg/cd_code
126    o ctrl package totally restructured
127      - pack/unpack now optional and decoupled from
128        xx_/adxx_ I/O
129      - ctrl_pack/unpack cleaned
130        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
131      - confined inclusion of AD_CONFIG.h to where necessary.
132    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
133    
134    checkpoint51p_post
135    o create initial cd_code package
136      - WARNING: the initialization of fields within packages
137        is broken because INI_FIELDS (where READ_CHECKPOINT is
138        called) is called *before* PACKAGES_INIT_VARIABLES.
139        This seems to be backwards since
140        1) its important to initially zero the entire field including
141           the "halo" region
142        2) zeroing needs to be done *before* reading pickup info
143           and the pickup call might or might not happen in any
144           particular run
145      - this needs an overhaul for R2
146    o cleanup verification/*/code/GMREDI_OPTIONS.h
147    o cleanup testreport
148    
149  checkpoint51o_post  checkpoint51o_post
150  o bringing AD-related verif's up to date with genmake2  o bringing AD-related verif's up to date with genmake2
