4      ==============================      ==============================
5    
6    checkpoint52h_pre
7    o shortened offending lines in exch2_send_rx?.template
8    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
9    o genmake2: add build & execute test for NetCDF code
10    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
11      old grid files, moved CPP_EEMACROS.h to pkg/exch2
12    o added useSingleCPUIO flag to monitor.F and mon_out.F
13    o added temporary hack for sea-ice dynamics on the cube:
14      metric terms are ignored and it is assumed that
15      there is no sea-ice on cube faces 1, 2, 4, and 5.
16    
17    checkpoint52f_post
18    o added exch2 cube routines to pkg/exch2
19    o modified hs94.cs-32x32x5 to use it
20    o added new grid files to hs94.cs-32x32x5
21    checkpoint52f_pre
22    
23    checkpoint52e_post
24    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
25      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
26    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
27      to work with implicit vertical advection and AB ;
28    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
29    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
30     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
31    checkpoint52e_pre
32    
33    o fix bug in impldiff when Nr=1 or Nr=2.
34    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
35    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
36    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
37      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
38    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
39    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
40    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
41    
42    checkpoint52d_post
43    o re-tiled many expts to allow comparison in multi-processor mode
44      - updated output accordingly
45      - changed hs94.128x64x5 to use intial T from file rather than use the
46        random number generator
47    o add infrastructure in model routines for fizhi and gridalt packages
48    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
49    o changes to permit hi-res, cubed-sphere, configuration
50      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
51      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
52      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
53        of surface winds for the cube
54      (A verification experiment, based on global_ocean.cs32x15, but with
55       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
56       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
57       complete with example surface forcing files and matlab scripts to look
58       at the output and compare it with that of global_ocean.cs32x15.)
59    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
60       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
61       to conform to the common rule.
62    o check-in the first version of the coupler + interfaces for multi-components
63       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
64       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
65       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
66       - ocean and atmos. share the same horizontal grid (no interpolation).
67       - exchanges between component and coupler is done in forward_step
68    o new verification experiment, cpl_aim+ocn:
69       coupled ocean - AIM atmosphere on cs32 grid.
70    
71    checkpoint52d_pre
72    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
73    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
74    
75    checkpoint52c_post
76    o Fixing OPTIONS files for use of exf:
77      - ALLOW_ECCO not needed
78      - ECCO_CPPOPTIONS.h should not be included from
79        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
80        as has been the case in the past
81      - All cal/exf related options are currently set in
82        single header file. Should remain so until we
83        agree on a consistent new policy.
84    o Removed all CPP options for cal package.
85      cal has no more CPP options.
86    o modified STOREs in GAD_ADVECTION
87    o corrected key comp. for passkey
88    
89    checkpoint52b_post
90    o new version: "thsice" of thermodynamic sea-ice pkg:
91     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
92     - modify fluxes but do not change theta directly;
93     - light cleaning of bulk_force pkg (still needed with thsice).
94     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
95       + output_thsice.txt to test thsice & bulk_force pkgs.
96    o put back grid & coriolis monitor output.
97    checkpoint52b_pre
98    
99    o call "do_the_model_io" at the beginning (=> dump initial state)
100    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
101    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
102      (need info on NUMBER_OF_PTRACERS)
103    o missing PTRACERS headers in some routines
104    o default tamc.h in pkg/autodiff supposed to crash
105      to ensure proper customization
106    
107    checkpoint52a_post
108    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
109      - moved surfaceTendencyTice from pkg/seaice to main code
110      - subroutine FREEZE_SURFACE now limits only surface temperature
111        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
112        => new output.txt for global_ocean.cs32x15 & global_with_exf
113      - keep the old version of FREEZE for backward compatibility;
114        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
115      - corresponding modifs for TAF directives
116    o added surface flux output variables to TIMEAVE_STATVARS
117    o time-averaged output for pkg/ptracers
118    o fix problem with ECCO-related divided adjoint
119      snapshot file was missing some ad-variables,
120      but no warning issued by TAF
121    
122    checkpoint52a_pre
123    o some bug fixes for #undef REAL4_IS_SLOW
124    
125    checkpoint52 = ecco_c52_e35
126    o after testing adjoints of checkpoint51u_post
127    
128    checkpoint51u_post
129    o this is the post-merge tag of the ecco-branch
130      (needs another clean checkout and re-testing)
131    o various natl_box_adjoint configs and results
132      but no input fields
133    o obcs adjoint not yet merged!
134    o adding ECCO global 1x1 and 2x2 degree configs
135    o updated/extended some store directives for seaice
136    o pkg/ecco now containes ecco-specific part of cost function
137    o top level routines the_main_loop, forward_step
138      supersede those in model/src/
139      previous input data.cost now in data.ecco
140      (new namelist ecco_cost_nml)
141    o in ctrl/ cleaned some cross-dependencies and updated CPP options
142    
143    checkpoint51t_post
144    o this is the pre-merge tag of the ecco-branch
145    
146    checkpoint51s_post
147    o cleanup: removed various obsolete #define-s
148    o pkg/grdchk
149      - renamed 'ph-grd 3' to 'grad-res'
150      - merged from ecco-branch
151        (remaining bug fixes for obcs gradient checks)
152      - additional high-precision output for testreport
153        (grep for 'precision_grdchk_result')
154    
155    checkpoint51r_post
156    o cleaned up or removed CPP_OPTIONS.h files
157    o updated results for some of the tests to reflect the new
158      optfiles (-ieee: -O0 instead of -O3)
159    
160  checkpoint51q_post  checkpoint51q_post
161  o cd_code:  o cd_code:
162    - moved cd_scheme.F -> cd_code_scheme.F    - moved cd_scheme.F -> cd_code_scheme.F
