4      ==============================      ==============================
5    
6  untagged  o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
7      mon_vort3.F to make exch2 friendly with >1 tile per cube
8      face
9    
10    checkpoint52i_post
11    o removed CPP_EEOPTIONS.h from verification/*/code
12    o updated the tiling for global_ocean_pressure
13    checkpoint52i_pre
14    
15    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
16      the old pkg/aim).
17    
18    checkpoint52h_pre
19    o shortened offending lines in exch2_send_rx?.template
20    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
21    o genmake2: add build & execute test for NetCDF code
22    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
23      old grid files, moved CPP_EEMACROS.h to pkg/exch2
24    o added useSingleCPUIO flag to monitor.F and mon_out.F
25    o added temporary hack for sea-ice dynamics on the cube:
26      metric terms are ignored and it is assumed that
27      there is no sea-ice on cube faces 1, 2, 4, and 5.
28    
29    checkpoint52f_post
30    o added exch2 cube routines to pkg/exch2
31    o modified hs94.cs-32x32x5 to use it
32    o added new grid files to hs94.cs-32x32x5
33    checkpoint52f_pre
34    
35    checkpoint52e_post
36    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
37      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
38    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
39      to work with implicit vertical advection and AB ;
40    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
41    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
42     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
43    checkpoint52e_pre
44    
45    o fix bug in impldiff when Nr=1 or Nr=2.
46    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
47    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
48    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
49      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
50    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
51    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
52    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
53    
54    checkpoint52d_post
55    o re-tiled many expts to allow comparison in multi-processor mode
56      - updated output accordingly
57      - changed hs94.128x64x5 to use intial T from file rather than use the
58        random number generator
59    o add infrastructure in model routines for fizhi and gridalt packages
60    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
61    o changes to permit hi-res, cubed-sphere, configuration
62      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
63      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
64      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
65        of surface winds for the cube
66      (A verification experiment, based on global_ocean.cs32x15, but with
67       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
68       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
69       complete with example surface forcing files and matlab scripts to look
70       at the output and compare it with that of global_ocean.cs32x15.)
71    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
72       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
73       to conform to the common rule.
74    o check-in the first version of the coupler + interfaces for multi-components
75       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
76       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
77       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
78       - ocean and atmos. share the same horizontal grid (no interpolation).
79       - exchanges between component and coupler is done in forward_step
80    o new verification experiment, cpl_aim+ocn:
81       coupled ocean - AIM atmosphere on cs32 grid.
82    
83    checkpoint52d_pre
84    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
85    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
86    
87    checkpoint52c_post
88    o Fixing OPTIONS files for use of exf:
89      - ALLOW_ECCO not needed
90      - ECCO_CPPOPTIONS.h should not be included from
91        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
92        as has been the case in the past
93      - All cal/exf related options are currently set in
94        single header file. Should remain so until we
95        agree on a consistent new policy.
96    o Removed all CPP options for cal package.
97      cal has no more CPP options.
98    o modified STOREs in GAD_ADVECTION
99    o corrected key comp. for passkey
100    
101    checkpoint52b_post
102    o new version: "thsice" of thermodynamic sea-ice pkg:
103     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
104     - modify fluxes but do not change theta directly;
105     - light cleaning of bulk_force pkg (still needed with thsice).
106     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
107       + output_thsice.txt to test thsice & bulk_force pkgs.
108    o put back grid & coriolis monitor output.
109    checkpoint52b_pre
110    
111    o call "do_the_model_io" at the beginning (=> dump initial state)
112    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
113    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
114      (need info on NUMBER_OF_PTRACERS)
115    o missing PTRACERS headers in some routines
116    o default tamc.h in pkg/autodiff supposed to crash
117      to ensure proper customization
118    
119    checkpoint52a_post
120    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
121      - moved surfaceTendencyTice from pkg/seaice to main code
122      - subroutine FREEZE_SURFACE now limits only surface temperature
123        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
124        => new output.txt for global_ocean.cs32x15 & global_with_exf
125      - keep the old version of FREEZE for backward compatibility;
126        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
127      - corresponding modifs for TAF directives
128    o added surface flux output variables to TIMEAVE_STATVARS
129    o time-averaged output for pkg/ptracers
130    o fix problem with ECCO-related divided adjoint

134    checkpoint52a_pre
135    o some bug fixes for #undef REAL4_IS_SLOW
136    
137    checkpoint52 = ecco_c52_e35
138    o after testing adjoints of checkpoint51u_post
139    
140    checkpoint51u_post
141    o this is the post-merge tag of the ecco-branch
142      (needs another clean checkout and re-testing)
143    o various natl_box_adjoint configs and results
144      but no input fields
145    o obcs adjoint not yet merged!
146    o adding ECCO global 1x1 and 2x2 degree configs
147    o updated/extended some store directives for seaice
148    o pkg/ecco now containes ecco-specific part of cost function
149    o top level routines the_main_loop, forward_step
150      supersede those in model/src/
151      previous input data.cost now in data.ecco
152      (new namelist ecco_cost_nml)
153    o in ctrl/ cleaned some cross-dependencies and updated CPP options
154    
155    checkpoint51t_post
156    o this is the pre-merge tag of the ecco-branch
157    
158    checkpoint51s_post
159    o cleanup: removed various obsolete #define-s
160    o pkg/grdchk
161      - renamed 'ph-grd 3' to 'grad-res'
162      - merged from ecco-branch
163        (remaining bug fixes for obcs gradient checks)
164      - additional high-precision output for testreport
165        (grep for 'precision_grdchk_result')
166    
167    checkpoint51r_post
168    o cleaned up or removed CPP_OPTIONS.h files
169    o updated results for some of the tests to reflect the new
170      optfiles (-ieee: -O0 instead of -O3)
171    
172    checkpoint51q_post
173    o cd_code:
174      - moved cd_scheme.F -> cd_code_scheme.F
175      - separate read_checkpoint from cd_code_ini_vars.F
176      - separated cd_code part from write_checkpoint
177      - updated AD_SOURCE, generated .flow
178      - added CD_CODE_VARS.h to the_main_loop
179      - Moving cd_code specific store dir.s to pkg/cd_code
180    o ctrl package totally restructured
181      - pack/unpack now optional and decoupled from
182        xx_/adxx_ I/O
183      - ctrl_pack/unpack cleaned
184        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
185      - confined inclusion of AD_CONFIG.h to where necessary.
186    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
187    
188    checkpoint51p_post
189    o create initial cd_code package
190      - WARNING: the initialization of fields within packages
191        is broken because INI_FIELDS (where READ_CHECKPOINT is
192        called) is called *before* PACKAGES_INIT_VARIABLES.
193        This seems to be backwards since
194        1) its important to initially zero the entire field including
195           the "halo" region
196        2) zeroing needs to be done *before* reading pickup info
197           and the pickup call might or might not happen in any
198           particular run
199      - this needs an overhaul for R2
200    o cleanup verification/*/code/GMREDI_OPTIONS.h
201    o cleanup testreport

211    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
212    o bug fix in find_alpha.F for MDJWF:
213      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
214        change rho -> rho-rhoConst
215      - replace call find_rho to find_rhonum
216    o initialisation of rFlx extended to full array (required by TAF)
217      and shifted to thermodynamics
218    o removed PTRACERS.h in ptracers routine
219    o added surfacetendencyPtr to S/R parameter list pracers_forcing
220    o Correcting initialisations for fVerU, fVerV.
221    o helping TAF to recognize dependency on kUp for
222      fVerU, fVerV

226    o undid all of cp51 pending some cleanups and discussion
227    o added the [#include "AD_CONFIG.h"] statement to all files that need
228       it for adjoint/tl #defines
229     o re-worked the build logic in genmake2 to support AD_CONFIG.h
230     o removed tools/genmake since it no longer works
231

233    o modifications to make FREEZE flux visible to pkg/kpp
234      - moved surfaceTendencyTice from pkg/seaice to main code
235      - FREEZE & EXTERNAL_FORCING_SURF moved to FORWARD_STEP
236      - subroutine FREEZE now limits only surface temperature
237        (this means new output.txt for global_ocean.90x40x15,
238         global_ocean.cs32x15, and global_with_exf)
239    o added surface flux output variables to TIMEAVE_STATVARS
240    
241    checkpoint51n_pre
242    o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F
243    o added [#include "AD_CONFIG.h"] to all files that use the following
