5    
6    checkpoint52 = ecco_c52_e35
7    o after testing adjoints of checkpoint51u_post
8    
9    checkpoint51u_post
10    o this is the post-merge tag of the ecco-branch
11      (needs another clean checkout and re-testing)
12    o various natl_box_adjoint configs and results
13      but no input fields
14    o obcs adjoint not yet merged!
15    o adding ECCO global 1x1 and 2x2 degree configs
16    o updated/extended some store directives for seaice
17    o pkg/ecco now containes ecco-specific part of cost function
18    o top level routines the_main_loop, forward_step
19      supersede those in model/src/
20      previous input data.cost now in data.ecco
21      (new namelist ecco_cost_nml)
22    o in ctrl/ cleaned some cross-dependencies and updated CPP options
23    
24    checkpoint51t_post
25    o this is the pre-merge tag of the ecco-branch
26    
27    checkpoint51s_post
28    o cleanup: removed various obsolete #define-s
29    o pkg/grdchk
30      - renamed 'ph-grd 3' to 'grad-res'
31      - merged from ecco-branch
32        (remaining bug fixes for obcs gradient checks)
33      - additional high-precision output for testreport
34        (grep for 'precision_grdchk_result')
35    
36    checkpoint51r_post
37    o cleaned up or removed CPP_OPTIONS.h files
38    o updated results for some of the tests to reflect the new
39      optfiles (-ieee: -O0 instead of -O3)
40    
41    checkpoint51q_post
42    o cd_code:
43      - moved cd_scheme.F -> cd_code_scheme.F
44      - separate read_checkpoint from cd_code_ini_vars.F
45      - separated cd_code part from write_checkpoint
46      - updated AD_SOURCE, generated .flow
47      - added CD_CODE_VARS.h to the_main_loop
48      - Moving cd_code specific store dir.s to pkg/cd_code
49    o ctrl package totally restructured
50      - pack/unpack now optional and decoupled from
51        xx_/adxx_ I/O
52      - ctrl_pack/unpack cleaned
53        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
54      - confined inclusion of AD_CONFIG.h to where necessary.
55    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
56    
57    checkpoint51p_post
58    o create initial cd_code package
59      - WARNING: the initialization of fields within packages
60        is broken because INI_FIELDS (where READ_CHECKPOINT is
61        called) is called *before* PACKAGES_INIT_VARIABLES.
62        This seems to be backwards since
63        1) its important to initially zero the entire field including
64           the "halo" region
65        2) zeroing needs to be done *before* reading pickup info
66           and the pickup call might or might not happen in any
67           particular run
68      - this needs an overhaul for R2
69    o cleanup verification/*/code/GMREDI_OPTIONS.h
70    o cleanup testreport
71    
72    checkpoint51o_post
73    o bringing AD-related verif's up to date with genmake2

79    o cleaning ALLOW_GRADIENT_CHECK -> ALLOW_GRDCHK
80    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
81    o bug fix in find_alpha.F for MDJWF:
82      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
83        change rho -> rho-rhoConst
84      - replace call find_rho to find_rhonum
85    o initialisation of rFlx extended to full array (required by TAF)
86      and shifted to thermodynamics
87    o removed PTRACERS.h in ptracers routine
88    o added surfacetendencyPtr to S/R parameter list pracers_forcing
89    o Correcting initialisations for fVerU, fVerV.
90    o helping TAF to recognize dependency on kUp for
91      fVerU, fVerV
92    o Replacing delZ by delR in pkg/ctrl/
93    checkpoint51o_pre

107         global_ocean.cs32x15, and global_with_exf)
108    o added surface flux output variables to TIMEAVE_STATVARS

110    checkpoint51n_pre
111    o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F

194      of tracer Green's fucntions for ocean inversion project.
195    
196    checkpoint51f_pre
197    o Added on-the-fly spatial interpolation capability
198        "USE_EXF_INTERPOLATION" to pkg/exf.
199      - This is a temporary Cartesian-grid hack until
200        the super-duper ESMF coupler becomes available.
201      - See verification/global_with_exf/README for usage example.
202      - Removed obsolete EXFwindOnBgrid and SEAICEwindOnCgrid

225    o Use cluster local disks for purely local I/O
226      vs. globally visible disks needed for ctrl stuff
227      (merged from ecco-branch)
228      - new active_file_loc... and mdsio_..._loc routines
229      - affected packages: autodiff, ctrl, grdchk, mdsio

235      - debLevB: equivalent to current debugMode=.TRUE.
236    o introducing pathname variable mdsioLocalDir for mdsio
237      that can be specified at runtime
238      (relevant for cluster I/O to local disk)
239    `
240    >>>checkpoint51b_post
241    adjoint of ptracers
242    o disentangled ALLOW_PTRACERS using new ALLOW_GCHEM

256      - new pkgs: dic, gchem
257      - new subroutine in ptracers
258    o modify code for biogeo packages
259      - in model/src and pkg/ptracers
260    
261    checkpoint51
262    o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN
263      - autodiff, ctrl, exf, grdchk, seaice
264      kept separate packages
265      - cost, ecco, obcs
266    o updating verification/internal_wave, verification/lab_sea
267      (all verif's pass on faulks.lcs.mit.edu RH7.3, g77)
268    
269    checkpoint50i_post
270    o Preparing next differentiable checkpoint and sync
271      of MAIN vs. ecco-branch
272      - 1st step: this one is differentiable
273      - 2nd step: next(! not this) checkpoint will have updated packages
274                  from ecco-branch)
275    
276    checkpoint50h_post
277    o new package "land": provide surface BC for AIM.
278    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
279    o AIM: use true log-P extrapolation for near surface temp (= as in
280        F.Molteni paper) ; update aim.5l_cs output.
281    o New variable in PARM03 for more flexible pickups
282    o somewhat cleaned package initialisation sequence for
283      ctrl/ cost/ ecco/ in packages_... routines
284    
285    checkpoint50g_post
286    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
287      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
288      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
289        made the default because of faster convergence than ADI
290    
291    checkpoint50f_post
292    o exf totally restructured
293      - replaced all exf_set_ routines by one generic exf_set_gen.F
294        and made sure it's still differentiable
295      - split exf_getffields.F into new exf_bulkformulae.F
296      - exf_inscal_/exf_outscal_ suffixes consistent with field names

307     o removed lots of single quotes from comments
308    
309    checkpoint50e_post
310    o make KPP work with PTRACERS
311     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
312       nearly a copy of kpp_transport_s
313     - there is no analogue to SurfaceTendencyS, so I have to use
314       gPtr(of the surface layer) instead
315    o add a new platform SunFire+mpi (SunFire 15000) to genmake
316    checkpoint50e_pre
317    
318    checkpoint50d_post
319    o change kpp output from multiple-record state files to single-record state
320      files analogous to write_state.F
321    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
322      analogous to the cg2d-related output.
323    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
324      so that writing to internal file fn (with length 512) fails.
325    checkpoint50d_pre
326    
327    checkpoint50c_post
328    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
329    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
330    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
331    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
332    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
333    
334    checkpoint50c_pre
335    Merging from release1_p13:
336    o bug fix for pkg/seaice dynamic solver
337    o Added SEAICE_initialHEFF to pkg/seaice
338    
339    checkpoint50b_post
340    o store u*,v* in gU,V instead of in guNm1,gvNm1
341    o in order to put the momForcing out of the Adams-Bashforth:
342      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
343      to timestep.F
344    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
345    o re-generate output for highly sensitive test-exp:
346       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
347    
348    checkpoint50b_pre
349    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
350    o corrected CPP option mismatch in exf_Bulk... functions for case
351      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
352    
353    checkpoint50a_post
354    o Bug fix for merging between c50 and KPP.
355      ikey was passed from thermodynamics to kpp_calc via
356      common block rather than being recomputed in kpp_calc,
357      in contradiction with new key itdkey.
358      New key ikppkey created, and tamc.h headers updated.
359    
360    checkpoint50
361    - 2nd step of merge with ecco-branch:
362      merge changes in ecco-branch back into main trunk
363    - bug fix in find_alpha
364    - more storing in gmredi_calc_tensor.F, kpp_routines.F
365    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
366    - merged some sliced AD support routines
367    
368    checkpoint49
369    merged from ecco-branch:
370    o exf:
371      - Enable initialisation of forcing fields to constant
372        (runtime) values.
373      - in exf_getffields.F
374        Reduce i-/j-loop to interior domain, discarding overlaps.
375        That also fixes wrong TAF-key computations for key_1, key_2
376        with bulf formulae.
377      - exf_init.F modify #ifdef for exf_init_evap
378      - exf_getffieldrec.F, ctrl_getrec.F
379        The following INT-usages are not safe:
380          fldsecs  = int(fldsecs/fldperiod)*fldperiod
381          fldcount = int(fldsecs/fldperiod) + 1
382        and were modified.
383    o autodiff: checkpoint_lev...
384      - updated storing for bulk formulae (some arrays were missing)
385      - added state for seaice package
386      - synchronized with main branch
387    o DIVA:
388      Modif.s in
389      - the_main_loop.F
390      - the_model_main.F
391      and added cost_final_restore.F cost_final_store.F
392      o With these changes, it is possible to fully separate
393        the first forward run to compute the cost function (mdthe_main_loop)
394        and adjoint runs over individual DIVA intervals (adthe_main_loop)
395        into separate model executions.
396        This enables better tuning of DIVA to given queue sizes.
397      o Loss of cost function value in consecutive DIVA runs is
398        fixed by storing to 'costfinal' file.
399      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
400        beginning/end of adjoint integration is accounted for.
401      The current changes apply to TAF-1.4.26.
402      TAF has one remaining bug, requiring one manual change
403      (see MITgcm manual).
404    o cal: synchronized between MAIN and ecco-branch
405    
406    checkpoint48i_post
407    o Changes to restore differentiability of code w.r.t. previous tag
408      (mostly adding new routines to make list and replacing
409      pressure by totPhiHyd).
410    o Updated and merged grdchk package
411      - has both ADM and TLM checks
412      - works for single- and multi-proc.
413      - output cleaned
414      - worked successfully for parallel DIVA
415    o genmake:
416      - Adding -platform=SP4
417      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
418    o Modif. for DIVA:
419      ctrl_unpack should not be called in intermediate DIVA interval.
420      (similar thing would apply for active files such as
421      tbar, sbar, psbar, which should not be reinitialised;
422      only relevant for ecco-branch)
423    
424    checkpoint48h_post
425    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
426    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
427    o Added SEAICE_initialHEFF to pkg/seaice
428    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
429    
430    checkpoint48g_post
431    --- EOS:
432    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
433      store total Potential in totPhyHyd for diagnostics & EOS.
434    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
435    --- Pressure/geopotential gradient:
436    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
437    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
438      ( changes results of global_ocean_pressure )
439    o NLFS + z-coord.: add eta*Rho' contribution.
440    o accurate phiHyd when using interface-W at the middle between 2 centers
441     ( changes results of ideal_2D_oce )
442    o includes r* 2nd term in potential gradient.

444    checkpoint48f_post
445    Merging from release1_p12:
446    o Modifications for using pkg/exf with pkg/seaice
447      - improved description of the various forcing configurations
448      - added basic radiation bulk formulae to pkg/exf
449      - units/sign fix for evap computation in exf_getffields.F
450      - updated verification/global_with_exf/results/output.txt
451    o Added pkg/sbo for computing IERS Special Bureau for the Oceans
452      (SBO) core products, including oceanic mass, center-of-mass,
453      angular, and bottom pressure (see pkg/sbo/README.sbo).
454    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
455      to avoid negative values in shallow regions.
456      - updated verification/natl_box/results/output.txt
457      - updated verification/lab_sea/results/output.txt
458    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
459    o Added useSingleCpuIO option (see PARAMS.h).
460    o Updated useSingleCpuIO option in mdsio_writefield.F to
461      work with multi-field files, e.g., for single-file pickup.
462    o pkg/seaice:
463      - bug fix in growth.F: QNET for no shortwave case
464      - added HeffFile for specifying initial sea-ice thickness
465      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
466    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
467      kpp_transport_t.F, forward_step.F, and the_main_loop.F
468    o pkg/seaice:
469      - adjoint-friendly modifications
470      - added a SEAICE_WRITE_PICKUP at end of the_model_main.F
471    
472    checkpoint48e_post
473    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
474    o dynamics: change definition of computational domain & adapt mom_fluxform
475      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
476    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
477        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
478        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
479        global_ocean.90x40x15 global_with_exf global_ocean_pressure
480        inverted_barometer solid-body.cs-32x32x1
481      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
482    
483    checkpoint48d_post
484    o in preparation for r*:
485     a) use pre-computed gradient of hydrostatic potential:
486        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
487     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
488        => affects results of glob_oce_pressure (different truncation error)  
489      update output.txt of ideal_2D_oce & global_ocean_pressure
490    
491    checkpoint48d_pre
492    o in preparation for r*:
493      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
494      pass the 2 comp. of the grad. as arguments to momentum S/R.
495      but for the moment, only used if it does not change the results.
496    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
497    
498    checkpoint48c_post
499    Modifications in treatment of initial flux forcing controls
500    to avoid extra storing of flux fields.
501    
502    checkpoint48c_pre
503  o Added tidal_basin_2d experiment (currently 1D!)  o Added tidal_basin_2d experiment (currently 1D!)
504  o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented)  o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented)
