4      ==============================      ==============================
5    
6    checkpoint52c_post
7    o Fixing OPTIONS files for use of exf:
8      - ALLOW_ECCO not needed
9      - ECCO_CPPOPTIONS.h should not be included from
10        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
11        as has been the case in the past
12      - All cal/exf related options are currently set in
13        single header file. Should remain so until we
14        agree on a consistent new policy.
15    o Removed all CPP options for cal package.
16      cal has no more CPP options.
17    o modified STOREs in GAD_ADVECTION
18    o corrected key comp. for passkey
19    
20    checkpoint52b_post
21    o new version: "thsice" of thermodynamic sea-ice pkg:
22     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
23     - modify fluxes but do not change theta directly;
24     - light cleaning of bulk_force pkg (still needed with thsice).
25     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
26       + output_thsice.txt to test thsice & bulk_force pkgs.
27    o put back grid & coriolis monitor output.
28    checkpoint52b_pre
29    
30    o call "do_the_model_io" at the beginning (=> dump initial state)
31    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
32    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
33      (need info on NUMBER_OF_PTRACERS)
34    o missing PTRACERS headers in some routines
35    o default tamc.h in pkg/autodiff supposed to crash
36      to ensure proper customization
37    
38    checkpoint52a_post
39    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
40      - moved surfaceTendencyTice from pkg/seaice to main code
41      - subroutine FREEZE_SURFACE now limits only surface temperature
42        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
43        => new output.txt for global_ocean.cs32x15 & global_with_exf
44      - keep the old version of FREEZE for backward compatibility;
45        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
46      - corresponding modifs for TAF directives
47    o added surface flux output variables to TIMEAVE_STATVARS
48    o time-averaged output for pkg/ptracers
49    o fix problem with ECCO-related divided adjoint
50      snapshot file was missing some ad-variables,
51      but no warning issued by TAF
52    
53    checkpoint52a_pre
54    o some bug fixes for #undef REAL4_IS_SLOW
55    
56    checkpoint52 = ecco_c52_e35
57    o after testing adjoints of checkpoint51u_post
58    
59    checkpoint51u_post
60    o this is the post-merge tag of the ecco-branch
61      (needs another clean checkout and re-testing)
62    o various natl_box_adjoint configs and results
63      but no input fields
64    o obcs adjoint not yet merged!
65    o adding ECCO global 1x1 and 2x2 degree configs
66    o updated/extended some store directives for seaice
67    o pkg/ecco now containes ecco-specific part of cost function
68    o top level routines the_main_loop, forward_step
69      supersede those in model/src/
70      previous input data.cost now in data.ecco
71      (new namelist ecco_cost_nml)
72    o in ctrl/ cleaned some cross-dependencies and updated CPP options
73    
74    checkpoint51t_post
75    o this is the pre-merge tag of the ecco-branch
76    
77    checkpoint51s_post
78    o cleanup: removed various obsolete #define-s
79    o pkg/grdchk
80      - renamed 'ph-grd 3' to 'grad-res'
81      - merged from ecco-branch
82        (remaining bug fixes for obcs gradient checks)
83      - additional high-precision output for testreport
84        (grep for 'precision_grdchk_result')
85    
86    checkpoint51r_post
87    o cleaned up or removed CPP_OPTIONS.h files
88    o updated results for some of the tests to reflect the new
89      optfiles (-ieee: -O0 instead of -O3)
90    
91    checkpoint51q_post
92    o cd_code:
93      - moved cd_scheme.F -> cd_code_scheme.F
94      - separate read_checkpoint from cd_code_ini_vars.F
95      - separated cd_code part from write_checkpoint
96      - updated AD_SOURCE, generated .flow
97      - added CD_CODE_VARS.h to the_main_loop
98      - Moving cd_code specific store dir.s to pkg/cd_code
99    o ctrl package totally restructured
100      - pack/unpack now optional and decoupled from
101        xx_/adxx_ I/O
102      - ctrl_pack/unpack cleaned
103        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
104      - confined inclusion of AD_CONFIG.h to where necessary.
105    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
106    
107    checkpoint51p_post
108    o create initial cd_code package
109      - WARNING: the initialization of fields within packages
110        is broken because INI_FIELDS (where READ_CHECKPOINT is
111        called) is called *before* PACKAGES_INIT_VARIABLES.
112        This seems to be backwards since
113        1) its important to initially zero the entire field including
114           the "halo" region
115        2) zeroing needs to be done *before* reading pickup info
116           and the pickup call might or might not happen in any
117           particular run
118      - this needs an overhaul for R2
119    o cleanup verification/*/code/GMREDI_OPTIONS.h
120    o cleanup testreport
121    
122    checkpoint51o_post
123    o bringing AD-related verif's up to date with genmake2

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

153      - moved surfaceTendencyTice from pkg/seaice to main code
154      - FREEZE & EXTERNAL_FORCING_SURF moved to FORWARD_STEP
155      - subroutine FREEZE now limits only surface temperature
156        (this means new output.txt for global_ocean.90x40x15,
157         global_ocean.cs32x15, and global_with_exf)
158    o added surface flux output variables to TIMEAVE_STATVARS

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

318    
319    checkpoint50i_post
320    o Preparing next differentiable checkpoint and sync
321      of MAIN vs. ecco-branch

324                  from ecco-branch)
325    
326    checkpoint50h_post
327    o new package "land": provide surface BC for AIM.

330        F.Molteni paper) ; update aim.5l_cs output.
331    o New variable in PARM03 for more flexible pickups
332    o somewhat cleaned package initialisation sequence for
333      ctrl/ cost/ ecco/ in packages_... routines

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

361     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
362       nearly a copy of kpp_transport_s
363     - there is no analogue to SurfaceTendencyS, so I have to use
364       gPtr(of the surface layer) instead
365    o add a new platform SunFire+mpi (SunFire 15000) to genmake
366    checkpoint50e_pre
367    
368    checkpoint50d_post
369    o change kpp output from multiple-record state files to single-record state
370      files analogous to write_state.F
371    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
372      analogous to the cg2d-related output.
373    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
374      so that writing to internal file fn (with length 512) fails.
375    checkpoint50d_pre
376    
377    checkpoint50c_post
378    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)

381    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
382    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
383    
384    checkpoint50c_pre
385    Merging from release1_p13:

387    o Added SEAICE_initialHEFF to pkg/seaice
388    
389    checkpoint50b_post
390    o store u*,v* in gU,V instead of in guNm1,gvNm1
391    o in order to put the momForcing out of the Adams-Bashforth:
392      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
393      to timestep.F
394    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
395    o re-generate output for highly sensitive test-exp:
396       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
397    
398    checkpoint50b_pre
399    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
400    o corrected CPP option mismatch in exf_Bulk... functions for case
401      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
402    
403    checkpoint50a_post
404    o Bug fix for merging between c50 and KPP.
405      ikey was passed from thermodynamics to kpp_calc via
406      common block rather than being recomputed in kpp_calc,
407      in contradiction with new key itdkey.
408      New key ikppkey created, and tamc.h headers updated.
409    
410    checkpoint50
411    - 2nd step of merge with ecco-branch:
412      merge changes in ecco-branch back into main trunk
413    - bug fix in find_alpha
414    - more storing in gmredi_calc_tensor.F, kpp_routines.F
415    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
416    - merged some sliced AD support routines
417    
418  checkpoint49  checkpoint49
419    merged from ecco-branch:
420    o exf:
421      - Enable initialisation of forcing fields to constant
422        (runtime) values.
423      - in exf_getffields.F
424        Reduce i-/j-loop to interior domain, discarding overlaps.
425        That also fixes wrong TAF-key computations for key_1, key_2
426        with bulf formulae.
427      - exf_init.F modify #ifdef for exf_init_evap
428      - exf_getffieldrec.F, ctrl_getrec.F
429        The following INT-usages are not safe:
430          fldsecs  = int(fldsecs/fldperiod)*fldperiod
431          fldcount = int(fldsecs/fldperiod) + 1
432        and were modified.
433    o autodiff: checkpoint_lev...
434      - updated storing for bulk formulae (some arrays were missing)
435      - added state for seaice package
436      - synchronized with main branch
437    o DIVA:
438      Modif.s in
439      - the_main_loop.F
440      - the_model_main.F
441      and added cost_final_restore.F cost_final_store.F
442      o With these changes, it is possible to fully separate
443        the first forward run to compute the cost function (mdthe_main_loop)
444        and adjoint runs over individual DIVA intervals (adthe_main_loop)
445        into separate model executions.
446        This enables better tuning of DIVA to given queue sizes.
447      o Loss of cost function value in consecutive DIVA runs is
448        fixed by storing to 'costfinal' file.
449      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
450        beginning/end of adjoint integration is accounted for.
451      The current changes apply to TAF-1.4.26.
452      TAF has one remaining bug, requiring one manual change
453      (see MITgcm manual).
454    o cal: synchronized between MAIN and ecco-branch
