3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    
6    o Fixing OPTIONS files for use of exf:
7      - ALLOW_ECCO not needed
8      - ECCO_CPPOPTIONS.h should not be included from
9        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
10        as has been the case in the past
11      - All cal/exf related options are currently set in
12        single header file. Should remain so until we
13        agree on a consistent new policy.
14    
15    checkpoint52b_post
16    o new version: "thsice" of thermodynamic sea-ice pkg:
17     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
18     - modify fluxes but do not change theta directly;
19     - light cleaning of bulk_force pkg (still needed with thsice).
20     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
21       + output_thsice.txt to test thsice & bulk_force pkgs.
22    o put back grid & coriolis monitor output.
23    checkpoint52b_pre
24    
25    o call "do_the_model_io" at the beginning (=> dump initial state)
26    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
27    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
28      (need info on NUMBER_OF_PTRACERS)
29    o missing PTRACERS headers in some routines
30    o default tamc.h in pkg/autodiff supposed to crash
31      to ensure proper customization
32    
33    checkpoint52a_post
34    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
35      - moved surfaceTendencyTice from pkg/seaice to main code
36      - subroutine FREEZE_SURFACE now limits only surface temperature
37        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
38        => new output.txt for global_ocean.cs32x15 & global_with_exf
39      - keep the old version of FREEZE for backward compatibility;
40        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
41      - corresponding modifs for TAF directives
42    o added surface flux output variables to TIMEAVE_STATVARS
43    o time-averaged output for pkg/ptracers
44    o fix problem with ECCO-related divided adjoint
45      snapshot file was missing some ad-variables,
46      but no warning issued by TAF
47    
48    checkpoint52a_pre
49    o some bug fixes for #undef REAL4_IS_SLOW
50    
51    checkpoint52 = ecco_c52_e35
52    o after testing adjoints of checkpoint51u_post
53    
54    checkpoint51u_post
55    o this is the post-merge tag of the ecco-branch
56      (needs another clean checkout and re-testing)
57    o various natl_box_adjoint configs and results
58      but no input fields
59    o obcs adjoint not yet merged!
60    o adding ECCO global 1x1 and 2x2 degree configs
61    o updated/extended some store directives for seaice
62    o pkg/ecco now containes ecco-specific part of cost function
63    o top level routines the_main_loop, forward_step
64      supersede those in model/src/
65      previous input data.cost now in data.ecco
66      (new namelist ecco_cost_nml)
67    o in ctrl/ cleaned some cross-dependencies and updated CPP options
68    
69    checkpoint51t_post
70    o this is the pre-merge tag of the ecco-branch
71    
72    checkpoint51s_post
73    o cleanup: removed various obsolete #define-s
74    o pkg/grdchk
75      - renamed 'ph-grd 3' to 'grad-res'
76      - merged from ecco-branch
77        (remaining bug fixes for obcs gradient checks)
78      - additional high-precision output for testreport
79        (grep for 'precision_grdchk_result')
80    
81    checkpoint51r_post
82    o cleaned up or removed CPP_OPTIONS.h files
83    o updated results for some of the tests to reflect the new
84      optfiles (-ieee: -O0 instead of -O3)
85    
86    checkpoint51q_post
87    o cd_code:
88      - moved cd_scheme.F -> cd_code_scheme.F
89      - separate read_checkpoint from cd_code_ini_vars.F
90      - separated cd_code part from write_checkpoint
91      - updated AD_SOURCE, generated .flow
92      - added CD_CODE_VARS.h to the_main_loop
93      - Moving cd_code specific store dir.s to pkg/cd_code
94    o ctrl package totally restructured
95      - pack/unpack now optional and decoupled from
96        xx_/adxx_ I/O
97      - ctrl_pack/unpack cleaned
98        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
99      - confined inclusion of AD_CONFIG.h to where necessary.
100    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
101    
102    checkpoint51p_post
103    o create initial cd_code package
104      - WARNING: the initialization of fields within packages
105        is broken because INI_FIELDS (where READ_CHECKPOINT is
106        called) is called *before* PACKAGES_INIT_VARIABLES.
107        This seems to be backwards since
108        1) its important to initially zero the entire field including
109           the "halo" region
110        2) zeroing needs to be done *before* reading pickup info
111           and the pickup call might or might not happen in any
112           particular run
113      - this needs an overhaul for R2
114    o cleanup verification/*/code/GMREDI_OPTIONS.h
115    o cleanup testreport
116    
117    checkpoint51o_post
118    o bringing AD-related verif's up to date with genmake2

124    o cleaning ALLOW_GRADIENT_CHECK -> ALLOW_GRDCHK
125    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
126    o bug fix in find_alpha.F for MDJWF:
127      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
128        change rho -> rho-rhoConst
129      - replace call find_rho to find_rhonum
130    o initialisation of rFlx extended to full array (required by TAF)
131      and shifted to thermodynamics
132    o removed PTRACERS.h in ptracers routine
133    o added surfacetendencyPtr to S/R parameter list pracers_forcing
134    o Correcting initialisations for fVerU, fVerV.
135    o helping TAF to recognize dependency on kUp for
136      fVerU, fVerV

149      - FREEZE & EXTERNAL_FORCING_SURF moved to FORWARD_STEP
150      - subroutine FREEZE now limits only surface temperature
151        (this means new output.txt for global_ocean.90x40x15,
152         global_ocean.cs32x15, and global_with_exf)
153    o added surface flux output variables to TIMEAVE_STATVARS

239      of tracer Green's fucntions for ocean inversion project.
240    
241    checkpoint51f_pre
242    o Added on-the-fly spatial interpolation capability
243        "USE_EXF_INTERPOLATION" to pkg/exf.
244      - This is a temporary Cartesian-grid hack until
245        the super-duper ESMF coupler becomes available.
246      - See verification/global_with_exf/README for usage example.
247      - Removed obsolete EXFwindOnBgrid and SEAICEwindOnCgrid

313    
314    checkpoint50i_post
315    o Preparing next differentiable checkpoint and sync
316      of MAIN vs. ecco-branch

325        F.Molteni paper) ; update aim.5l_cs output.
326    o New variable in PARM03 for more flexible pickups
327    o somewhat cleaned package initialisation sequence for
328      ctrl/ cost/ ecco/ in packages_... routines
329    
330    checkpoint50g_post

332      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
333      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
334        made the default because of faster convergence than ADI
335    
336    checkpoint50f_post
337    o exf totally restructured
338      - replaced all exf_set_ routines by one generic exf_set_gen.F
339        and made sure it's still differentiable
340      - split exf_getffields.F into new exf_bulkformulae.F

356     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
357       nearly a copy of kpp_transport_s
358     - there is no analogue to SurfaceTendencyS, so I have to use
359       gPtr(of the surface layer) instead
360    o add a new platform SunFire+mpi (SunFire 15000) to genmake
361    checkpoint50e_pre
362

364    o change kpp output from multiple-record state files to single-record state
365      files analogous to write_state.F
366    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
367      analogous to the cg2d-related output.
368    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
369      so that writing to internal file fn (with length 512) fails.
370    checkpoint50d_pre
371    
372    checkpoint50c_post

382    o Added SEAICE_initialHEFF to pkg/seaice
383    
384    checkpoint50b_post
385    o store u*,v* in gU,V instead of in guNm1,gvNm1
386    o in order to put the momForcing out of the Adams-Bashforth:
387      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
388      to timestep.F
389    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
390    o re-generate output for highly sensitive test-exp:
391       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
392    
393    checkpoint50b_pre
394    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
395    o corrected CPP option mismatch in exf_Bulk... functions for case
396      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
397    
398    checkpoint50a_post
399    o Bug fix for merging between c50 and KPP.
400      ikey was passed from thermodynamics to kpp_calc via
401      common block rather than being recomputed in kpp_calc,
402      in contradiction with new key itdkey.
403      New key ikppkey created, and tamc.h headers updated.
404    
405    checkpoint50
406    - 2nd step of merge with ecco-branch:
407      merge changes in ecco-branch back into main trunk
408    - bug fix in find_alpha
409    - more storing in gmredi_calc_tensor.F, kpp_routines.F
410    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC

412    
413    checkpoint49
414    merged from ecco-branch:
415    o exf:
416      - Enable initialisation of forcing fields to constant
417        (runtime) values.
418      - in exf_getffields.F
419        Reduce i-/j-loop to interior domain, discarding overlaps.
420        That also fixes wrong TAF-key computations for key_1, key_2
421        with bulf formulae.
422      - exf_init.F modify #ifdef for exf_init_evap
423      - exf_getffieldrec.F, ctrl_getrec.F
424        The following INT-usages are not safe:
425          fldsecs  = int(fldsecs/fldperiod)*fldperiod
426          fldcount = int(fldsecs/fldperiod) + 1
427        and were modified.
428    o autodiff: checkpoint_lev...
429      - updated storing for bulk formulae (some arrays were missing)
430      - added state for seaice package
431      - synchronized with main branch
432    o DIVA:
433      Modif.s in
434      - the_main_loop.F
435      - the_model_main.F
436      and added cost_final_restore.F cost_final_store.F
437      o With these changes, it is possible to fully separate
438        the first forward run to compute the cost function (mdthe_main_loop)
439        and adjoint runs over individual DIVA intervals (adthe_main_loop)
440        into separate model executions.
441        This enables better tuning of DIVA to given queue sizes.
442      o Loss of cost function value in consecutive DIVA runs is
443        fixed by storing to 'costfinal' file.
444      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
445        beginning/end of adjoint integration is accounted for.
446      The current changes apply to TAF-1.4.26.
447      TAF has one remaining bug, requiring one manual change
448      (see MITgcm manual).
449    o cal: synchronized between MAIN and ecco-branch
450    
451    checkpoint48i_post
452    o Changes to restore differentiability of code w.r.t. previous tag
453      (mostly adding new routines to make list and replacing
454      pressure by totPhiHyd).
455    o Updated and merged grdchk package
456      - has both ADM and TLM checks
457      - works for single- and multi-proc.
458      - output cleaned
459      - worked successfully for parallel DIVA
460    o genmake:
461      - Adding -platform=SP4
462      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
463    o Modif. for DIVA:
464      ctrl_unpack should not be called in intermediate DIVA interval.
465      (similar thing would apply for active files such as
466      tbar, sbar, psbar, which should not be reinitialised;
467      only relevant for ecco-branch)
468    
469    checkpoint48h_post
470    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
471    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
472    o Added SEAICE_initialHEFF to pkg/seaice
473    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
474    
475    checkpoint48g_post
476    --- EOS:
477    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
478      store total Potential in totPhyHyd for diagnostics & EOS.
479    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
480    --- Pressure/geopotential gradient:
481    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
482    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
483      ( changes results of global_ocean_pressure )
484    o NLFS + z-coord.: add eta*Rho' contribution.
485    o accurate phiHyd when using interface-W at the middle between 2 centers
486     ( changes results of ideal_2D_oce )
487    o includes r* 2nd term in potential gradient.
488    
489    checkpoint48f_post
490    Merging from release1_p12:
491    o Modifications for using pkg/exf with pkg/seaice
492      - improved description of the various forcing configurations
493      - added basic radiation bulk formulae to pkg/exf
494      - units/sign fix for evap computation in exf_getffields.F
495      - updated verification/global_with_exf/results/output.txt
496    o Added pkg/sbo for computing IERS Special Bureau for the Oceans
497      (SBO) core products, including oceanic mass, center-of-mass,
498      angular, and bottom pressure (see pkg/sbo/README.sbo).
499    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
500      to avoid negative values in shallow regions.
501      - updated verification/natl_box/results/output.txt
502      - updated verification/lab_sea/results/output.txt
503    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
504    o Added useSingleCpuIO option (see PARAMS.h).
505    o Updated useSingleCpuIO option in mdsio_writefield.F to
506      work with multi-field files, e.g., for single-file pickup.
507    o pkg/seaice:
508      - bug fix in growth.F: QNET for no shortwave case
509      - added HeffFile for specifying initial sea-ice thickness
510      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
511    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
512      kpp_transport_t.F, forward_step.F, and the_main_loop.F
513    o pkg/seaice:
514      - adjoint-friendly modifications
515      - added a SEAICE_WRITE_PICKUP at end of the_model_main.F
516    
517    checkpoint48e_post
518    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
519    o dynamics: change definition of computational domain & adapt mom_fluxform
520      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
521    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
522        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
523        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
524        global_ocean.90x40x15 global_with_exf global_ocean_pressure
525        inverted_barometer solid-body.cs-32x32x1
526      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
527    
528    checkpoint48d_post
529    o in preparation for r*:
530     a) use pre-computed gradient of hydrostatic potential:
531        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
532     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
533        => affects results of glob_oce_pressure (different truncation error)  
534      update output.txt of ideal_2D_oce & global_ocean_pressure
535    
536    checkpoint48d_pre
537    o in preparation for r*:
538      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
539      pass the 2 comp. of the grad. as arguments to momentum S/R.
540      but for the moment, only used if it does not change the results.
541    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
