5    
6    checkpoint52e_pre
7    
8    o fix bug in impldiff when Nr=1 or Nr=2.
9    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
10    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
11    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
12      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
13    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
14    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
15    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
16    
17    checkpoint52d_post
18    o re-tiled many expts to allow comparison in multi-processor mode
19      - updated output accordingly
20      - changed hs94.128x64x5 to use intial T from file rather than use the
21        random number generator
22    o add infrastructure in model routines for fizhi and gridalt packages
23    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
24    o changes to permit hi-res, cubed-sphere, configuration
25      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
26      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
27      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
28        of surface winds for the cube
29      (A verification experiment, based on global_ocean.cs32x15, but with
30       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
31       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
32       complete with example surface forcing files and matlab scripts to look
33       at the output and compare it with that of global_ocean.cs32x15.)
34    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
35       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
36       to conform to the common rule.
37    o check-in the first version of the coupler + interfaces for multi-components
38       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
39       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
40       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
41       - ocean and atmos. share the same horizontal grid (no interpolation).
42       - exchanges between component and coupler is done in forward_step
43    o new verification experiment, cpl_aim+ocn:
44       coupled ocean - AIM atmosphere on cs32 grid.
45    
46    checkpoint52d_pre
47    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
48    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
49    
50    checkpoint52c_post
51    o Fixing OPTIONS files for use of exf:
52      - ALLOW_ECCO not needed
53      - ECCO_CPPOPTIONS.h should not be included from
54        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
55        as has been the case in the past
56      - All cal/exf related options are currently set in
57        single header file. Should remain so until we
58        agree on a consistent new policy.
59    o Removed all CPP options for cal package.
60      cal has no more CPP options.
61    o modified STOREs in GAD_ADVECTION
62    o corrected key comp. for passkey
63    
64    checkpoint52b_post
65    o new version: "thsice" of thermodynamic sea-ice pkg:
66     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
67     - modify fluxes but do not change theta directly;
68     - light cleaning of bulk_force pkg (still needed with thsice).
69     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
70       + output_thsice.txt to test thsice & bulk_force pkgs.
71    o put back grid & coriolis monitor output.
72    checkpoint52b_pre
73    
74    o call "do_the_model_io" at the beginning (=> dump initial state)
75    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
76    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
77      (need info on NUMBER_OF_PTRACERS)
78    o missing PTRACERS headers in some routines
79    o default tamc.h in pkg/autodiff supposed to crash
80      to ensure proper customization
81    
82    checkpoint52a_post
83    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
84      - moved surfaceTendencyTice from pkg/seaice to main code
85      - subroutine FREEZE_SURFACE now limits only surface temperature
86        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
87        => new output.txt for global_ocean.cs32x15 & global_with_exf
88      - keep the old version of FREEZE for backward compatibility;
89        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
90      - corresponding modifs for TAF directives
91    o added surface flux output variables to TIMEAVE_STATVARS
92    o time-averaged output for pkg/ptracers
93    o fix problem with ECCO-related divided adjoint
94      snapshot file was missing some ad-variables,
95      but no warning issued by TAF
96    
97    checkpoint52a_pre
98    o some bug fixes for #undef REAL4_IS_SLOW
99    
100    checkpoint52 = ecco_c52_e35
101    o after testing adjoints of checkpoint51u_post
102    
103    checkpoint51u_post
104    o this is the post-merge tag of the ecco-branch
105      (needs another clean checkout and re-testing)
106    o various natl_box_adjoint configs and results
107      but no input fields
108    o obcs adjoint not yet merged!
109    o adding ECCO global 1x1 and 2x2 degree configs
110    o updated/extended some store directives for seaice
111    o pkg/ecco now containes ecco-specific part of cost function
112    o top level routines the_main_loop, forward_step
113      supersede those in model/src/
114      previous input data.cost now in data.ecco
115      (new namelist ecco_cost_nml)
116    o in ctrl/ cleaned some cross-dependencies and updated CPP options
117    
118    checkpoint51t_post
119    o this is the pre-merge tag of the ecco-branch
120    
121    checkpoint51s_post
122    o cleanup: removed various obsolete #define-s
123    o pkg/grdchk
124      - renamed 'ph-grd 3' to 'grad-res'
125      - merged from ecco-branch
126        (remaining bug fixes for obcs gradient checks)
127      - additional high-precision output for testreport
128        (grep for 'precision_grdchk_result')
129    
130    checkpoint51r_post
131    o cleaned up or removed CPP_OPTIONS.h files
132    o updated results for some of the tests to reflect the new
133      optfiles (-ieee: -O0 instead of -O3)
134    
135    checkpoint51q_post
136    o cd_code:
137      - moved cd_scheme.F -> cd_code_scheme.F
138      - separate read_checkpoint from cd_code_ini_vars.F
139      - separated cd_code part from write_checkpoint
140      - updated AD_SOURCE, generated .flow
141      - added CD_CODE_VARS.h to the_main_loop
142      - Moving cd_code specific store dir.s to pkg/cd_code
143    o ctrl package totally restructured
144      - pack/unpack now optional and decoupled from
145        xx_/adxx_ I/O
146      - ctrl_pack/unpack cleaned
147        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
148      - confined inclusion of AD_CONFIG.h to where necessary.
149    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
150    
151    checkpoint51p_post
152    o create initial cd_code package
153      - WARNING: the initialization of fields within packages
154        is broken because INI_FIELDS (where READ_CHECKPOINT is
155        called) is called *before* PACKAGES_INIT_VARIABLES.
156        This seems to be backwards since
157        1) its important to initially zero the entire field including
158           the "halo" region
159        2) zeroing needs to be done *before* reading pickup info
160           and the pickup call might or might not happen in any
161           particular run
162      - this needs an overhaul for R2
163    o cleanup verification/*/code/GMREDI_OPTIONS.h
164    o cleanup testreport

174    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
175    o bug fix in find_alpha.F for MDJWF:
176      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
177        change rho -> rho-rhoConst
178      - replace call find_rho to find_rhonum
179    o initialisation of rFlx extended to full array (required by TAF)
180      and shifted to thermodynamics
181    o removed PTRACERS.h in ptracers routine
182    o added surfacetendencyPtr to S/R parameter list pracers_forcing
183    o Correcting initialisations for fVerU, fVerV.

201         global_ocean.cs32x15, and global_with_exf)
202    o added surface flux output variables to TIMEAVE_STATVARS
203    
204    checkpoint51n_pre
205    o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F
