3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    
6    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
7      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
8    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
9    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
10    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
11    
12    checkpoint52d_post
13    o re-tiled many expts to allow comparison in multi-processor mode
14      - updated output accordingly
15      - changed hs94.128x64x5 to use intial T from file rather than use the
16        random number generator
17    o add infrastructure in model routines for fizhi and gridalt packages
18    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
19    o changes to permit hi-res, cubed-sphere, configuration
20      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
21      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
22      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
23        of surface winds for the cube
24      (A verification experiment, based on global_ocean.cs32x15, but with
25       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
26       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
27       complete with example surface forcing files and matlab scripts to look
28       at the output and compare it with that of global_ocean.cs32x15.)
29    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
30       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
31       to conform to the common rule.
32    o check-in the first version of the coupler + interfaces for multi-components
33       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
34       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
35       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
36       - ocean and atmos. share the same horizontal grid (no interpolation).
37       - exchanges between component and coupler is done in forward_step
38    o new verification experiment, cpl_aim+ocn:
39       coupled ocean - AIM atmosphere on cs32 grid.
40    
41    checkpoint52d_pre
42    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
43    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
44    
45    checkpoint52c_post
46    o Fixing OPTIONS files for use of exf:
47      - ALLOW_ECCO not needed
48      - ECCO_CPPOPTIONS.h should not be included from
49        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
50        as has been the case in the past
51      - All cal/exf related options are currently set in
52        single header file. Should remain so until we
53        agree on a consistent new policy.
54    o Removed all CPP options for cal package.
55      cal has no more CPP options.
56    o modified STOREs in GAD_ADVECTION
57    o corrected key comp. for passkey
58    
59    checkpoint52b_post
60    o new version: "thsice" of thermodynamic sea-ice pkg:
61     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
62     - modify fluxes but do not change theta directly;
63     - light cleaning of bulk_force pkg (still needed with thsice).
64     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
65       + output_thsice.txt to test thsice & bulk_force pkgs.
66    o put back grid & coriolis monitor output.
67    checkpoint52b_pre
68    
69    o call "do_the_model_io" at the beginning (=> dump initial state)
70    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
71    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
72      (need info on NUMBER_OF_PTRACERS)
73    o missing PTRACERS headers in some routines
74    o default tamc.h in pkg/autodiff supposed to crash
75      to ensure proper customization
76    
77    checkpoint52a_post
78    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
79      - moved surfaceTendencyTice from pkg/seaice to main code
80      - subroutine FREEZE_SURFACE now limits only surface temperature
81        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
82        => new output.txt for global_ocean.cs32x15 & global_with_exf
83      - keep the old version of FREEZE for backward compatibility;
84        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
85      - corresponding modifs for TAF directives
86    o added surface flux output variables to TIMEAVE_STATVARS
87    o time-averaged output for pkg/ptracers
88    o fix problem with ECCO-related divided adjoint

94    
95    checkpoint52 = ecco_c52_e35
96    o after testing adjoints of checkpoint51u_post
97    
98    checkpoint51u_post
99    o this is the post-merge tag of the ecco-branch
100      (needs another clean checkout and re-testing)
101    o various natl_box_adjoint configs and results
102      but no input fields
103    o obcs adjoint not yet merged!
104    o adding ECCO global 1x1 and 2x2 degree configs
105    o updated/extended some store directives for seaice
106    o pkg/ecco now containes ecco-specific part of cost function
107    o top level routines the_main_loop, forward_step
108      supersede those in model/src/
109      previous input data.cost now in data.ecco
110      (new namelist ecco_cost_nml)
111    o in ctrl/ cleaned some cross-dependencies and updated CPP options
112    
113    checkpoint51t_post
114    o this is the pre-merge tag of the ecco-branch
115    
116    checkpoint51s_post
117    o cleanup: removed various obsolete #define-s
118    o pkg/grdchk
119      - renamed 'ph-grd 3' to 'grad-res'
120      - merged from ecco-branch
121        (remaining bug fixes for obcs gradient checks)
122      - additional high-precision output for testreport
123        (grep for 'precision_grdchk_result')
124    
125    checkpoint51r_post
126    o cleaned up or removed CPP_OPTIONS.h files
127    o updated results for some of the tests to reflect the new
128      optfiles (-ieee: -O0 instead of -O3)
129    
130    checkpoint51q_post
131    o cd_code:
132      - moved cd_scheme.F -> cd_code_scheme.F
133      - separate read_checkpoint from cd_code_ini_vars.F
134      - separated cd_code part from write_checkpoint
135      - updated AD_SOURCE, generated .flow
136      - added CD_CODE_VARS.h to the_main_loop
137      - Moving cd_code specific store dir.s to pkg/cd_code
138    o ctrl package totally restructured
139      - pack/unpack now optional and decoupled from
140        xx_/adxx_ I/O
141      - ctrl_pack/unpack cleaned
142        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
143      - confined inclusion of AD_CONFIG.h to where necessary.
144    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
145    
146    checkpoint51p_post
147    o create initial cd_code package
148      - WARNING: the initialization of fields within packages
149        is broken because INI_FIELDS (where READ_CHECKPOINT is
150        called) is called *before* PACKAGES_INIT_VARIABLES.
151        This seems to be backwards since
152        1) its important to initially zero the entire field including
153           the "halo" region
154        2) zeroing needs to be done *before* reading pickup info
155           and the pickup call might or might not happen in any
156           particular run
157      - this needs an overhaul for R2
158    o cleanup verification/*/code/GMREDI_OPTIONS.h
159    o cleanup testreport

169    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
170    o bug fix in find_alpha.F for MDJWF:
171      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
172        change rho -> rho-rhoConst
173      - replace call find_rho to find_rhonum
174    o initialisation of rFlx extended to full array (required by TAF)
175      and shifted to thermodynamics
176    o removed PTRACERS.h in ptracers routine
177    o added surfacetendencyPtr to S/R parameter list pracers_forcing

378        made the default because of faster convergence than ADI
379    
380    checkpoint50f_post
381    o exf totally restructured
382      - replaced all exf_set_ routines by one generic exf_set_gen.F
383        and made sure it's still differentiable
384      - split exf_getffields.F into new exf_bulkformulae.F

401       nearly a copy of kpp_transport_s
402     - there is no analogue to SurfaceTendencyS, so I have to use
403       gPtr(of the surface layer) instead
404    o add a new platform SunFire+mpi (SunFire 15000) to genmake
405    checkpoint50e_pre

423    checkpoint50c_pre
424    Merging from release1_p13:
425    o bug fix for pkg/seaice dynamic solver
426    o Added SEAICE_initialHEFF to pkg/seaice
427    
428    checkpoint50b_post
429    o store u*,v* in gU,V instead of in guNm1,gvNm1
430    o in order to put the momForcing out of the Adams-Bashforth:
431      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
432      to timestep.F
433    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
434    o re-generate output for highly sensitive test-exp:
435       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
436    
437    checkpoint50b_pre
438    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
439    o corrected CPP option mismatch in exf_Bulk... functions for case
440      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
441    
442    checkpoint50a_post
443    o Bug fix for merging between c50 and KPP.
444      ikey was passed from thermodynamics to kpp_calc via
445      common block rather than being recomputed in kpp_calc,
446      in contradiction with new key itdkey.
447      New key ikppkey created, and tamc.h headers updated.
448    
449    checkpoint50
450    - 2nd step of merge with ecco-branch:
451      merge changes in ecco-branch back into main trunk
452    - bug fix in find_alpha
453    - more storing in gmredi_calc_tensor.F, kpp_routines.F
454    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
455    - merged some sliced AD support routines
456    
457  checkpoint49  checkpoint49
458    merged from ecco-branch:
459    o exf:
460      - Enable initialisation of forcing fields to constant
461        (runtime) values.
462      - in exf_getffields.F
463        Reduce i-/j-loop to interior domain, discarding overlaps.
464        That also fixes wrong TAF-key computations for key_1, key_2
465        with bulf formulae.
466      - exf_init.F modify #ifdef for exf_init_evap
467      - exf_getffieldrec.F, ctrl_getrec.F
468        The following INT-usages are not safe:
469          fldsecs  = int(fldsecs/fldperiod)*fldperiod
470          fldcount = int(fldsecs/fldperiod) + 1
471        and were modified.
472    o autodiff: checkpoint_lev...
473      - updated storing for bulk formulae (some arrays were missing)
474      - added state for seaice package
475      - synchronized with main branch
476    o DIVA:
477      Modif.s in
478      - the_main_loop.F
479      - the_model_main.F
480      and added cost_final_restore.F cost_final_store.F
481      o With these changes, it is possible to fully separate
482        the first forward run to compute the cost function (mdthe_main_loop)
483        and adjoint runs over individual DIVA intervals (adthe_main_loop)
484        into separate model executions.
485        This enables better tuning of DIVA to given queue sizes.
486      o Loss of cost function value in consecutive DIVA runs is
487        fixed by storing to 'costfinal' file.
488      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
489        beginning/end of adjoint integration is accounted for.
490      The current changes apply to TAF-1.4.26.
491      TAF has one remaining bug, requiring one manual change
492      (see MITgcm manual).
493    o cal: synchronized between MAIN and ecco-branch
494    
495    checkpoint48i_post
496  o Changes to restore differentiability of code w.r.t. previous tag  o Changes to restore differentiability of code w.r.t. previous tag
497    (mostly adding new routines to make list and replacing    (mostly adding new routines to make list and replacing
498    pressure by totPhiHyd).    pressure by totPhiHyd).
