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

128      but no warning issued by TAF
129    
130    checkpoint52a_pre
131    o some bug fixes for #undef REAL4_IS_SLOW
132    
133    checkpoint52 = ecco_c52_e35
134    o after testing adjoints of checkpoint51u_post
135    
136    checkpoint51u_post
137    o this is the post-merge tag of the ecco-branch
138      (needs another clean checkout and re-testing)
139    o various natl_box_adjoint configs and results
140      but no input fields
141    o obcs adjoint not yet merged!
142    o adding ECCO global 1x1 and 2x2 degree configs
143    o updated/extended some store directives for seaice
144    o pkg/ecco now containes ecco-specific part of cost function
145    o top level routines the_main_loop, forward_step
146      supersede those in model/src/
147      previous input data.cost now in data.ecco
148      (new namelist ecco_cost_nml)
149    o in ctrl/ cleaned some cross-dependencies and updated CPP options
150    
151    checkpoint51t_post
152    o this is the pre-merge tag of the ecco-branch
153    
154    checkpoint51s_post
155    o cleanup: removed various obsolete #define-s
156    o pkg/grdchk
157      - renamed 'ph-grd 3' to 'grad-res'
158      - merged from ecco-branch
159        (remaining bug fixes for obcs gradient checks)
160      - additional high-precision output for testreport
161        (grep for 'precision_grdchk_result')
162    
163    checkpoint51r_post
164    o cleaned up or removed CPP_OPTIONS.h files
165    o updated results for some of the tests to reflect the new
166      optfiles (-ieee: -O0 instead of -O3)
167    
168    checkpoint51q_post
169    o cd_code:
170      - moved cd_scheme.F -> cd_code_scheme.F
171      - separate read_checkpoint from cd_code_ini_vars.F
172      - separated cd_code part from write_checkpoint
173      - updated AD_SOURCE, generated .flow
174      - added CD_CODE_VARS.h to the_main_loop
175      - Moving cd_code specific store dir.s to pkg/cd_code
176    o ctrl package totally restructured
177      - pack/unpack now optional and decoupled from
178        xx_/adxx_ I/O
179      - ctrl_pack/unpack cleaned
180        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
181      - confined inclusion of AD_CONFIG.h to where necessary.
182    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
183    
184    checkpoint51p_post
185    o create initial cd_code package
186      - WARNING: the initialization of fields within packages
187        is broken because INI_FIELDS (where READ_CHECKPOINT is
188        called) is called *before* PACKAGES_INIT_VARIABLES.
189        This seems to be backwards since
190        1) its important to initially zero the entire field including
191           the "halo" region
192        2) zeroing needs to be done *before* reading pickup info
193           and the pickup call might or might not happen in any
194           particular run
195      - this needs an overhaul for R2
196    o cleanup verification/*/code/GMREDI_OPTIONS.h
197    o cleanup testreport
198    
199    checkpoint51o_post
200    o bringing AD-related verif's up to date with genmake2

206    o cleaning ALLOW_GRADIENT_CHECK -> ALLOW_GRDCHK
207    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
208    o bug fix in find_alpha.F for MDJWF:
209      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
210        change rho -> rho-rhoConst
211      - replace call find_rho to find_rhonum
212    o initialisation of rFlx extended to full array (required by TAF)
213      and shifted to thermodynamics
214    o removed PTRACERS.h in ptracers routine
215    o added surfacetendencyPtr to S/R parameter list pracers_forcing
216    o Correcting initialisations for fVerU, fVerV.
217    o helping TAF to recognize dependency on kUp for
218      fVerU, fVerV
219    o Replacing delZ by delR in pkg/ctrl/
220    checkpoint51o_pre
221    
222    o undid all of cp51 pending some cleanups and discussion
223    o added the [#include "AD_CONFIG.h"] statement to all files that need
224       it for adjoint/tl #defines
225     o re-worked the build logic in genmake2 to support AD_CONFIG.h
226     o removed tools/genmake since it no longer works
227    
228    checkpoint51n_post
229    o modifications to make FREEZE flux visible to pkg/kpp
230      - moved surfaceTendencyTice from pkg/seaice to main code
231      - FREEZE & EXTERNAL_FORCING_SURF moved to FORWARD_STEP
232      - subroutine FREEZE now limits only surface temperature
233        (this means new output.txt for global_ocean.90x40x15,
234         global_ocean.cs32x15, and global_with_exf)
235    o added surface flux output variables to TIMEAVE_STATVARS
236    
237    checkpoint51n_pre
238    o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F
239    o added [#include "AD_CONFIG.h"] to all files that use the following
240      defines:
241      - ALLOW_ADJOINT_RUN
242      - ALLOW_TANGENTLINEAR_RUN
243      - ALLOW_ECCO_OPTIMIZATION
244    
245    checkpoint51m_post
246    o incorporating changes to get TAMC/TAF working in genmake2
247      - added new TAMC/TAF targets to the Makefile
248      - various cleanups related to package handling
249      - these changes should have no impact on the forward model

255     - pkg/exf *startdate variables changed from calendar date to
256       model integration time
257    
258    checkpoint51l_pre
259    o add salt flux to forcing fields (used when salty sea-ice forms or melts)
260    o enable to apply restoring on S & T only in a latitude band.
261    o update output (external_forcing_surf modif. change truncation errors)
262       global_ocean.cs32x15, global_ocean_pressure, lab_sea, natl_box
263    
264    checkpoint51k_post
265    o change default to: useNHMTerms=.FALSE.
266     - new output.txt for atmos. exp (NHMTerms were wrong but now turned off):
267       adjustment.128x64x1, aim.5l_Eq_Ch, aim.5l_LatLon, hs94.128x64x5, hs94.1x64x5
