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

148    o cleaning ALLOW_GRADIENT_CHECK -> ALLOW_GRDCHK
149    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
150    o bug fix in find_alpha.F for MDJWF:
151      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
152        change rho -> rho-rhoConst
153      - replace call find_rho to find_rhonum
154    o initialisation of rFlx extended to full array (required by TAF)
155      and shifted to thermodynamics
156    o removed PTRACERS.h in ptracers routine
157    o added surfacetendencyPtr to S/R parameter list pracers_forcing
158    o Correcting initialisations for fVerU, fVerV.
159    o helping TAF to recognize dependency on kUp for

176         global_ocean.cs32x15, and global_with_exf)
177    o added surface flux output variables to TIMEAVE_STATVARS
178    
179    checkpoint51n_pre
180    o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F
