3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    
6    o shortened offending lines in exch2_send_rx?.template
7    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
8    o genmake2: add build & execute test for NetCDF code
9    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
10      old grid files, moved CPP_EEMACROS.h to pkg/exch2
11    o added useSingleCPUIO flag to monitor.F and mon_out.F
12    o added temporary hack for sea-ice dynamics on the cube:
13      metric terms are ignored and it is assumed that
14      there is no sea-ice on cube faces 1, 2, 4, and 5.
15    
16    checkpoint52f_post
17    o added exch2 cube routines to pkg/exch2
18    o modified hs94.cs-32x32x5 to use it
19    o added new grid files to hs94.cs-32x32x5
20    checkpoint52f_pre
21    
22    checkpoint52e_post
23    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
24      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
25    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
26      to work with implicit vertical advection and AB ;
27    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
28    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
29     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
30    checkpoint52e_pre
31    
32    o fix bug in impldiff when Nr=1 or Nr=2.
33    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
34    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
35    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
36      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
37    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
38    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
39    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
40    
41    checkpoint52d_post
42    o re-tiled many expts to allow comparison in multi-processor mode
43      - updated output accordingly
44      - changed hs94.128x64x5 to use intial T from file rather than use the
45        random number generator
46    o add infrastructure in model routines for fizhi and gridalt packages
47    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
48    o changes to permit hi-res, cubed-sphere, configuration
49      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
50      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
51      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
52        of surface winds for the cube
53      (A verification experiment, based on global_ocean.cs32x15, but with
54       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
55       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
56       complete with example surface forcing files and matlab scripts to look
57       at the output and compare it with that of global_ocean.cs32x15.)
58    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
59       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
60       to conform to the common rule.
61    o check-in the first version of the coupler + interfaces for multi-components
62       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
63       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
64       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
65       - ocean and atmos. share the same horizontal grid (no interpolation).
66       - exchanges between component and coupler is done in forward_step
67    o new verification experiment, cpl_aim+ocn:
68       coupled ocean - AIM atmosphere on cs32 grid.
69    
70    checkpoint52d_pre
71    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
72    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
73    
74    checkpoint52c_post
75    o Fixing OPTIONS files for use of exf:
76      - ALLOW_ECCO not needed
77      - ECCO_CPPOPTIONS.h should not be included from
78        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
79        as has been the case in the past
80      - All cal/exf related options are currently set in
81        single header file. Should remain so until we
82        agree on a consistent new policy.
83    o Removed all CPP options for cal package.
84      cal has no more CPP options.
85    o modified STOREs in GAD_ADVECTION
86    o corrected key comp. for passkey
87    
88    checkpoint52b_post
89    o new version: "thsice" of thermodynamic sea-ice pkg:
90     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
91     - modify fluxes but do not change theta directly;
92     - light cleaning of bulk_force pkg (still needed with thsice).
93     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
94       + output_thsice.txt to test thsice & bulk_force pkgs.
95    o put back grid & coriolis monitor output.
96    checkpoint52b_pre
97    
98    o call "do_the_model_io" at the beginning (=> dump initial state)
99    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
100    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
101      (need info on NUMBER_OF_PTRACERS)
102    o missing PTRACERS headers in some routines
103    o default tamc.h in pkg/autodiff supposed to crash
104      to ensure proper customization
105    
106    checkpoint52a_post
107    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
108      - moved surfaceTendencyTice from pkg/seaice to main code
109      - subroutine FREEZE_SURFACE now limits only surface temperature
110        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
111        => new output.txt for global_ocean.cs32x15 & global_with_exf
112      - keep the old version of FREEZE for backward compatibility;
113        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
114      - corresponding modifs for TAF directives
115    o added surface flux output variables to TIMEAVE_STATVARS
116    o time-averaged output for pkg/ptracers
117    o fix problem with ECCO-related divided adjoint
118      snapshot file was missing some ad-variables,
119      but no warning issued by TAF
120    
121    checkpoint52a_pre
122    o some bug fixes for #undef REAL4_IS_SLOW
123    
124    checkpoint52 = ecco_c52_e35
125    o after testing adjoints of checkpoint51u_post
126    
127    checkpoint51u_post
128    o this is the post-merge tag of the ecco-branch
129      (needs another clean checkout and re-testing)
130    o various natl_box_adjoint configs and results
131      but no input fields
132    o obcs adjoint not yet merged!
133    o adding ECCO global 1x1 and 2x2 degree configs
134    o updated/extended some store directives for seaice
135    o pkg/ecco now containes ecco-specific part of cost function
136    o top level routines the_main_loop, forward_step
137      supersede those in model/src/
138      previous input data.cost now in data.ecco
139      (new namelist ecco_cost_nml)
140    o in ctrl/ cleaned some cross-dependencies and updated CPP options
141    
142    checkpoint51t_post
143    o this is the pre-merge tag of the ecco-branch
144    
145    checkpoint51s_post
146    o cleanup: removed various obsolete #define-s
147    o pkg/grdchk
148      - renamed 'ph-grd 3' to 'grad-res'
149      - merged from ecco-branch
150        (remaining bug fixes for obcs gradient checks)
151      - additional high-precision output for testreport
152        (grep for 'precision_grdchk_result')
153    
154    checkpoint51r_post
155    o cleaned up or removed CPP_OPTIONS.h files
156    o updated results for some of the tests to reflect the new
157      optfiles (-ieee: -O0 instead of -O3)
158    
159    checkpoint51q_post
160    o cd_code:
161      - moved cd_scheme.F -> cd_code_scheme.F
162      - separate read_checkpoint from cd_code_ini_vars.F
163      - separated cd_code part from write_checkpoint
164      - updated AD_SOURCE, generated .flow
165      - added CD_CODE_VARS.h to the_main_loop
166      - Moving cd_code specific store dir.s to pkg/cd_code
167    o ctrl package totally restructured
168      - pack/unpack now optional and decoupled from
169        xx_/adxx_ I/O
170      - ctrl_pack/unpack cleaned
171        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
172      - confined inclusion of AD_CONFIG.h to where necessary.
173    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
174    
175    checkpoint51p_post
176    o create initial cd_code package
177      - WARNING: the initialization of fields within packages
178        is broken because INI_FIELDS (where READ_CHECKPOINT is
179        called) is called *before* PACKAGES_INIT_VARIABLES.
180        This seems to be backwards since
181        1) its important to initially zero the entire field including
182           the "halo" region
183        2) zeroing needs to be done *before* reading pickup info
184           and the pickup call might or might not happen in any
185           particular run
186      - this needs an overhaul for R2
187    o cleanup verification/*/code/GMREDI_OPTIONS.h
188    o cleanup testreport
189    
190    checkpoint51o_post
191    o bringing AD-related verif's up to date with genmake2

195      - (front_relax/ )
196    o (more) consistent directory structure for AD-related verif.'s
197    o cleaning ALLOW_GRADIENT_CHECK -> ALLOW_GRDCHK
198    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
199    o bug fix in find_alpha.F for MDJWF:
200      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
201        change rho -> rho-rhoConst
202      - replace call find_rho to find_rhonum
203    o initialisation of rFlx extended to full array (required by TAF)
204      and shifted to thermodynamics
205    o removed PTRACERS.h in ptracers routine
206    o added surfacetendencyPtr to S/R parameter list pracers_forcing
207    o Correcting initialisations for fVerU, fVerV.
208    o helping TAF to recognize dependency on kUp for
209      fVerU, fVerV
210    o Replacing delZ by delR in pkg/ctrl/
211    checkpoint51o_pre
212    
213    o undid all of cp51 pending some cleanups and discussion
214    o added the [#include "AD_CONFIG.h"] statement to all files that need
215       it for adjoint/tl #defines
216     o re-worked the build logic in genmake2 to support AD_CONFIG.h
217     o removed tools/genmake since it no longer works
218    
219    checkpoint51n_post
220    o modifications to make FREEZE flux visible to pkg/kpp
221      - moved surfaceTendencyTice from pkg/seaice to main code
222      - FREEZE & EXTERNAL_FORCING_SURF moved to FORWARD_STEP
223      - subroutine FREEZE now limits only surface temperature
224        (this means new output.txt for global_ocean.90x40x15,
225         global_ocean.cs32x15, and global_with_exf)
226    o added surface flux output variables to TIMEAVE_STATVARS
227    
228    checkpoint51n_pre
229    o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F
230    o added [#include "AD_CONFIG.h"] to all files that use the following
231      defines:
232      - ALLOW_ADJOINT_RUN
233      - ALLOW_TANGENTLINEAR_RUN
234      - ALLOW_ECCO_OPTIMIZATION
