3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    
6  untagged  o mask vorticity at the corner ; affects global_ocean.cs output
7    o fix ini_curvilinear_grid ; test CS experiments with mpi
8    o aim.5l_cs: modify sea-ice fraction input file ; update output
9    
10    checkpoint52k_post
11    o removed top-level directory "diags"
12      - we migrated these functions to pkg/timeave a long time ago
13    o fixed bug introduced in pkg/monitor
14    o accuracy ctrlprec = 32 insuffient for gradient checks using
15      averaged fields (I/O via cost_averages)
16      -> use ctrl.h in active_file*.F to control I/O precision.
17    o paramter list of CALL ADTHE_MAIN_LOOP
18    o added initial do_the_model_io to ecco
19    o set all ...Freq to zero after cost_final
20      taveFreq, dumpFreq, pChkptFreq
21    o MAIN and ECCO differentiability restored
22    
23    checkpoint52j_post
24    o fix nchklev in tamc.h for global_ocean...
25    o Bringing flow and store directives up-to-date
26    o Really weird thing!
27      call do_the_model_io from the_main_loop with parameters
28      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
29      TAF places a faulty re-call of initialise_varia
30      after cost_final call which should not be there!
31    checkpoint52j_pre
32    
33    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
34      error messages
35    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
36    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
37      debug output
38    o modfied mdsio_writefield.F to handle non-global files under exch2
39    o update AIM Cubed-Sphere exp (aim.5l_cs):
40      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
41    o update AIM Equatorial Channel exp:
42      use standard aim_v23 pkg and change the SST fields to be more realistic.
43    o globalFile now works with exch2
44    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
45      mon_vort3.F to make exch2 friendly with >1 tile per cube face
46    o limit timeave output for hi-res integrations
47    
48    checkpoint52i_post
49    o removed CPP_EEOPTIONS.h from verification/*/code
50    o updated the tiling for global_ocean_pressure
51    checkpoint52i_pre
52    
53    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
54      the old pkg/aim).
55    
56    checkpoint52h_pre
57    o shortened offending lines in exch2_send_rx?.template
58    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
59    o genmake2: add build & execute test for NetCDF code
60    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
61      old grid files, moved CPP_EEMACROS.h to pkg/exch2
62    o added useSingleCPUIO flag to monitor.F and mon_out.F
63    o added temporary hack for sea-ice dynamics on the cube:
64      metric terms are ignored and it is assumed that
65      there is no sea-ice on cube faces 1, 2, 4, and 5.
66    
67    checkpoint52f_post
68    o added exch2 cube routines to pkg/exch2
69    o modified hs94.cs-32x32x5 to use it
70    o added new grid files to hs94.cs-32x32x5
71    checkpoint52f_pre
72    
73    checkpoint52e_post
74    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
75      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
76    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
77      to work with implicit vertical advection and AB ;
78    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
79    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
80     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
81    checkpoint52e_pre
82    
83    o fix bug in impldiff when Nr=1 or Nr=2.
84    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
85    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
86    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
87      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
88    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
89    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
90    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
91    
92    checkpoint52d_post
93    o re-tiled many expts to allow comparison in multi-processor mode
94      - updated output accordingly
95      - changed hs94.128x64x5 to use intial T from file rather than use the
96        random number generator
97    o add infrastructure in model routines for fizhi and gridalt packages
98    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
99    o changes to permit hi-res, cubed-sphere, configuration
100      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
101      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
102      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
103        of surface winds for the cube
104      (A verification experiment, based on global_ocean.cs32x15, but with
105       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
106       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
107       complete with example surface forcing files and matlab scripts to look
108       at the output and compare it with that of global_ocean.cs32x15.)
109    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
110       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
111       to conform to the common rule.
112    o check-in the first version of the coupler + interfaces for multi-components
113       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
114       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
115       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
116       - ocean and atmos. share the same horizontal grid (no interpolation).
117       - exchanges between component and coupler is done in forward_step
118    o new verification experiment, cpl_aim+ocn:
119       coupled ocean - AIM atmosphere on cs32 grid.
120    
121    checkpoint52d_pre
122    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
123    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
124    
125    checkpoint52c_post
126    o Fixing OPTIONS files for use of exf:
127      - ALLOW_ECCO not needed
128      - ECCO_CPPOPTIONS.h should not be included from
129        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
130        as has been the case in the past
131      - All cal/exf related options are currently set in
132        single header file. Should remain so until we
133        agree on a consistent new policy.
134    o Removed all CPP options for cal package.
135      cal has no more CPP options.
136    o modified STOREs in GAD_ADVECTION
137    o corrected key comp. for passkey
138    
139    checkpoint52b_post
140    o new version: "thsice" of thermodynamic sea-ice pkg:
141     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
142     - modify fluxes but do not change theta directly;
143     - light cleaning of bulk_force pkg (still needed with thsice).
144     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
145       + output_thsice.txt to test thsice & bulk_force pkgs.
146    o put back grid & coriolis monitor output.
147    checkpoint52b_pre
148    
149    o call "do_the_model_io" at the beginning (=> dump initial state)
150    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
151    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
152      (need info on NUMBER_OF_PTRACERS)
153    o missing PTRACERS headers in some routines
154    o default tamc.h in pkg/autodiff supposed to crash
155      to ensure proper customization
156    
157    checkpoint52a_post
158    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
159      - moved surfaceTendencyTice from pkg/seaice to main code
160      - subroutine FREEZE_SURFACE now limits only surface temperature
161        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
162        => new output.txt for global_ocean.cs32x15 & global_with_exf
163      - keep the old version of FREEZE for backward compatibility;
164        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
165      - corresponding modifs for TAF directives
166    o added surface flux output variables to TIMEAVE_STATVARS
167    o time-averaged output for pkg/ptracers
168    o fix problem with ECCO-related divided adjoint

170      but no warning issued by TAF
171    
172    checkpoint52a_pre
173    o some bug fixes for #undef REAL4_IS_SLOW
174    
175    checkpoint52 = ecco_c52_e35
176    o after testing adjoints of checkpoint51u_post
177    
178    checkpoint51u_post
179    o this is the post-merge tag of the ecco-branch
180      (needs another clean checkout and re-testing)
181    o various natl_box_adjoint configs and results
182      but no input fields
183    o obcs adjoint not yet merged!
184    o adding ECCO global 1x1 and 2x2 degree configs
185    o updated/extended some store directives for seaice
186    o pkg/ecco now containes ecco-specific part of cost function
187    o top level routines the_main_loop, forward_step
188      supersede those in model/src/
189      previous input data.cost now in data.ecco
190      (new namelist ecco_cost_nml)
191    o in ctrl/ cleaned some cross-dependencies and updated CPP options
192    
193    checkpoint51t_post
194    o this is the pre-merge tag of the ecco-branch
195    
196    checkpoint51s_post
197    o cleanup: removed various obsolete #define-s
198    o pkg/grdchk
199      - renamed 'ph-grd 3' to 'grad-res'
200      - merged from ecco-branch
201        (remaining bug fixes for obcs gradient checks)
202      - additional high-precision output for testreport
203        (grep for 'precision_grdchk_result')
204    
205    checkpoint51r_post
206    o cleaned up or removed CPP_OPTIONS.h files
207    o updated results for some of the tests to reflect the new
208      optfiles (-ieee: -O0 instead of -O3)
209    
210    checkpoint51q_post
211    o cd_code:
212      - moved cd_scheme.F -> cd_code_scheme.F
213      - separate read_checkpoint from cd_code_ini_vars.F
214      - separated cd_code part from write_checkpoint
215      - updated AD_SOURCE, generated .flow
216      - added CD_CODE_VARS.h to the_main_loop
217      - Moving cd_code specific store dir.s to pkg/cd_code
218    o ctrl package totally restructured
219      - pack/unpack now optional and decoupled from
220        xx_/adxx_ I/O
221      - ctrl_pack/unpack cleaned
222        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
223      - confined inclusion of AD_CONFIG.h to where necessary.
224    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
225    
226    checkpoint51p_post
227    o create initial cd_code package
228      - WARNING: the initialization of fields within packages
229        is broken because INI_FIELDS (where READ_CHECKPOINT is
230        called) is called *before* PACKAGES_INIT_VARIABLES.
231        This seems to be backwards since
232        1) its important to initially zero the entire field including
233           the "halo" region
234        2) zeroing needs to be done *before* reading pickup info
235           and the pickup call might or might not happen in any
236           particular run
237      - this needs an overhaul for R2
238    o cleanup verification/*/code/GMREDI_OPTIONS.h
239    o cleanup testreport
240    
241    checkpoint51o_post
242    o bringing AD-related verif's up to date with genmake2

248    o cleaning ALLOW_GRADIENT_CHECK -> ALLOW_GRDCHK
249    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
250    o bug fix in find_alpha.F for MDJWF:
251      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
252        change rho -> rho-rhoConst
253      - replace call find_rho to find_rhonum
254    o initialisation of rFlx extended to full array (required by TAF)
255      and shifted to thermodynamics
256    o removed PTRACERS.h in ptracers routine
257    o added surfacetendencyPtr to S/R parameter list pracers_forcing

266       it for adjoint/tl #defines
267     o re-worked the build logic in genmake2 to support AD_CONFIG.h
268     o removed tools/genmake since it no longer works
269    
270    checkpoint51n_post
271    o modifications to make FREEZE flux visible to pkg/kpp
272      - moved surfaceTendencyTice from pkg/seaice to main code
273      - FREEZE & EXTERNAL_FORCING_SURF moved to FORWARD_STEP
274      - subroutine FREEZE now limits only surface temperature
275        (this means new output.txt for global_ocean.90x40x15,
276         global_ocean.cs32x15, and global_with_exf)
277    o added surface flux output variables to TIMEAVE_STATVARS
278    
279    checkpoint51n_pre
280    o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F
