4      ==============================      ==============================
5    
6  checkpoint 51i_pre  o modfied mdsio_writefield.F to handle non-global files under exch2
7    o update AIM Cubed-Sphere exp (aim.5l_cs):
8      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
9    o update AIM Equatorial Channel exp:
10      use standard aim_v23 pkg and change the SST fields to be more realistic.
11    o globalFile now works with exch2
12    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
13      mon_vort3.F to make exch2 friendly with >1 tile per cube
14      face
15    o limit timeave output for hi-res integrations
16    
17    checkpoint52i_post
18    o removed CPP_EEOPTIONS.h from verification/*/code
19    o updated the tiling for global_ocean_pressure
20    checkpoint52i_pre
21    
22    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
23      the old pkg/aim).
24    
25    checkpoint52h_pre
26    o shortened offending lines in exch2_send_rx?.template
27    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
28    o genmake2: add build & execute test for NetCDF code
29    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
30      old grid files, moved CPP_EEMACROS.h to pkg/exch2
31    o added useSingleCPUIO flag to monitor.F and mon_out.F
32    o added temporary hack for sea-ice dynamics on the cube:
33      metric terms are ignored and it is assumed that
34      there is no sea-ice on cube faces 1, 2, 4, and 5.
35    
36    checkpoint52f_post
37    o added exch2 cube routines to pkg/exch2
38    o modified hs94.cs-32x32x5 to use it
39    o added new grid files to hs94.cs-32x32x5
40    checkpoint52f_pre
41    
42    checkpoint52e_post
43    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
44      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
45    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
46      to work with implicit vertical advection and AB ;
47    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
48    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
49     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
50    checkpoint52e_pre
51    
52    o fix bug in impldiff when Nr=1 or Nr=2.

54    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
55    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
56      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
57    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
58    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
59    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
60    
61    checkpoint52d_post
62    o re-tiled many expts to allow comparison in multi-processor mode
63      - updated output accordingly
64      - changed hs94.128x64x5 to use intial T from file rather than use the
65        random number generator
66    o add infrastructure in model routines for fizhi and gridalt packages
67    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
68    o changes to permit hi-res, cubed-sphere, configuration
69      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
70      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
71      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
72        of surface winds for the cube
73      (A verification experiment, based on global_ocean.cs32x15, but with
74       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
75       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
76       complete with example surface forcing files and matlab scripts to look
77       at the output and compare it with that of global_ocean.cs32x15.)
78    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
79       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
80       to conform to the common rule.
81    o check-in the first version of the coupler + interfaces for multi-components
82       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
83       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
84       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
85       - ocean and atmos. share the same horizontal grid (no interpolation).
86       - exchanges between component and coupler is done in forward_step
87    o new verification experiment, cpl_aim+ocn:
88       coupled ocean - AIM atmosphere on cs32 grid.
89    
90    checkpoint52d_pre
91    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
92    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
93    
94    checkpoint52c_post
95    o Fixing OPTIONS files for use of exf:
96      - ALLOW_ECCO not needed
97      - ECCO_CPPOPTIONS.h should not be included from
98        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
99        as has been the case in the past
100      - All cal/exf related options are currently set in
101        single header file. Should remain so until we
102        agree on a consistent new policy.
103    o Removed all CPP options for cal package.
104      cal has no more CPP options.
105    o modified STOREs in GAD_ADVECTION
106    o corrected key comp. for passkey
107    
108    checkpoint52b_post
109    o new version: "thsice" of thermodynamic sea-ice pkg:
110     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
111     - modify fluxes but do not change theta directly;
112     - light cleaning of bulk_force pkg (still needed with thsice).
113     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
114       + output_thsice.txt to test thsice & bulk_force pkgs.
115    o put back grid & coriolis monitor output.
116    checkpoint52b_pre
117    
118    o call "do_the_model_io" at the beginning (=> dump initial state)
119    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
120    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
121      (need info on NUMBER_OF_PTRACERS)
122    o missing PTRACERS headers in some routines
123    o default tamc.h in pkg/autodiff supposed to crash
124      to ensure proper customization
125    
126    checkpoint52a_post
127    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
128      - moved surfaceTendencyTice from pkg/seaice to main code
129      - subroutine FREEZE_SURFACE now limits only surface temperature
130        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
131        => new output.txt for global_ocean.cs32x15 & global_with_exf
132      - keep the old version of FREEZE for backward compatibility;
133        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
134      - corresponding modifs for TAF directives
135    o added surface flux output variables to TIMEAVE_STATVARS
136    o time-averaged output for pkg/ptracers
137    o fix problem with ECCO-related divided adjoint

142    o some bug fixes for #undef REAL4_IS_SLOW
143    
144    checkpoint52 = ecco_c52_e35
145    o after testing adjoints of checkpoint51u_post
146    
147    checkpoint51u_post
148    o this is the post-merge tag of the ecco-branch
149      (needs another clean checkout and re-testing)
150    o various natl_box_adjoint configs and results
151      but no input fields
152    o obcs adjoint not yet merged!
153    o adding ECCO global 1x1 and 2x2 degree configs
154    o updated/extended some store directives for seaice
155    o pkg/ecco now containes ecco-specific part of cost function
156    o top level routines the_main_loop, forward_step
157      supersede those in model/src/
158      previous input data.cost now in data.ecco
159      (new namelist ecco_cost_nml)
160    o in ctrl/ cleaned some cross-dependencies and updated CPP options
161    
162    checkpoint51t_post
163    o this is the pre-merge tag of the ecco-branch
164    
165    checkpoint51s_post
166    o cleanup: removed various obsolete #define-s
167    o pkg/grdchk
168      - renamed 'ph-grd 3' to 'grad-res'
169      - merged from ecco-branch
170        (remaining bug fixes for obcs gradient checks)
171      - additional high-precision output for testreport
172        (grep for 'precision_grdchk_result')
173    
174    checkpoint51r_post
175    o cleaned up or removed CPP_OPTIONS.h files
176    o updated results for some of the tests to reflect the new
177      optfiles (-ieee: -O0 instead of -O3)
178    
179    checkpoint51q_post
180    o cd_code:
181      - moved cd_scheme.F -> cd_code_scheme.F
182      - separate read_checkpoint from cd_code_ini_vars.F
183      - separated cd_code part from write_checkpoint
184      - updated AD_SOURCE, generated .flow
185      - added CD_CODE_VARS.h to the_main_loop
186      - Moving cd_code specific store dir.s to pkg/cd_code
187    o ctrl package totally restructured
188      - pack/unpack now optional and decoupled from
189        xx_/adxx_ I/O
190      - ctrl_pack/unpack cleaned
191        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
192      - confined inclusion of AD_CONFIG.h to where necessary.
193    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
194    
195    checkpoint51p_post
196    o create initial cd_code package
197      - WARNING: the initialization of fields within packages
198        is broken because INI_FIELDS (where READ_CHECKPOINT is
199        called) is called *before* PACKAGES_INIT_VARIABLES.
200        This seems to be backwards since
201        1) its important to initially zero the entire field including
202           the "halo" region
203        2) zeroing needs to be done *before* reading pickup info
204           and the pickup call might or might not happen in any
205           particular run
206      - this needs an overhaul for R2
207    o cleanup verification/*/code/GMREDI_OPTIONS.h
208    o cleanup testreport
209    
210    checkpoint51o_post

217    o cleaning ALLOW_GRADIENT_CHECK -> ALLOW_GRDCHK
218    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
219    o bug fix in find_alpha.F for MDJWF:
220      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
221        change rho -> rho-rhoConst
222      - replace call find_rho to find_rhonum
223    o initialisation of rFlx extended to full array (required by TAF)
224      and shifted to thermodynamics
225    o removed PTRACERS.h in ptracers routine
226    o added surfacetendencyPtr to S/R parameter list pracers_forcing
227    o Correcting initialisations for fVerU, fVerV.
228    o helping TAF to recognize dependency on kUp for
229      fVerU, fVerV
230    o Replacing delZ by delR in pkg/ctrl/
231    checkpoint51o_pre
232    
233    o undid all of cp51 pending some cleanups and discussion
234    o added the [#include "AD_CONFIG.h"] statement to all files that need
235       it for adjoint/tl #defines
236     o re-worked the build logic in genmake2 to support AD_CONFIG.h
237     o removed tools/genmake since it no longer works
238

241      - moved surfaceTendencyTice from pkg/seaice to main code
242      - FREEZE & EXTERNAL_FORCING_SURF moved to FORWARD_STEP
243      - subroutine FREEZE now limits only surface temperature
244        (this means new output.txt for global_ocean.90x40x15,
245         global_ocean.cs32x15, and global_with_exf)
246    o added surface flux output variables to TIMEAVE_STATVARS
247    
248    checkpoint51n_pre
249    o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F

273       global_ocean.cs32x15, global_ocean_pressure, lab_sea, natl_box
274    
275    checkpoint51k_post
276    o change default to: useNHMTerms=.FALSE.
277     - new output.txt for atmos. exp (NHMTerms were wrong but now turned off):
278       adjustment.128x64x1, aim.5l_Eq_Ch, aim.5l_LatLon, hs94.128x64x5, hs94.1x64x5
