4      ==============================      ==============================
5    
6    checkpoint51s_post
7    o cleanup: removed various obsolete #define-s
8    
9    checkpoint51r_post
10    o cleaned up or removed CPP_OPTIONS.h files
11    o updated results for some of the tests to reflect the new
12      optfiles (-ieee: -O0 instead of -O3)
13    
14    checkpoint51q_post
15    o cd_code:
16      - moved cd_scheme.F -> cd_code_scheme.F
17      - separate read_checkpoint from cd_code_ini_vars.F
18      - separated cd_code part from write_checkpoint
19      - updated AD_SOURCE, generated .flow
20      - added CD_CODE_VARS.h to the_main_loop
21      - Moving cd_code specific store dir.s to pkg/cd_code
22    o ctrl package totally restructured
23      - pack/unpack now optional and decoupled from
24        xx_/adxx_ I/O
25      - ctrl_pack/unpack cleaned
26        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
27      - confined inclusion of AD_CONFIG.h to where necessary.
28    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
29    
30    checkpoint51p_post
31    o create initial cd_code package
32      - WARNING: the initialization of fields within packages
33        is broken because INI_FIELDS (where READ_CHECKPOINT is
34        called) is called *before* PACKAGES_INIT_VARIABLES.
35        This seems to be backwards since
36        1) its important to initially zero the entire field including
37           the "halo" region
38        2) zeroing needs to be done *before* reading pickup info
39           and the pickup call might or might not happen in any
40           particular run
41      - this needs an overhaul for R2
42    o cleanup verification/*/code/GMREDI_OPTIONS.h
43    o cleanup testreport
44    
45    checkpoint51o_post
46    o bringing AD-related verif's up to date with genmake2

52    o cleaning ALLOW_GRADIENT_CHECK -> ALLOW_GRDCHK
53    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
54    o bug fix in find_alpha.F for MDJWF:
55      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
56        change rho -> rho-rhoConst
57      - replace call find_rho to find_rhonum
58    o initialisation of rFlx extended to full array (required by TAF)
59      and shifted to thermodynamics
60    o removed PTRACERS.h in ptracers routine
61    o added surfacetendencyPtr to S/R parameter list pracers_forcing
62    o Correcting initialisations for fVerU, fVerV.
63    o helping TAF to recognize dependency on kUp for
64      fVerU, fVerV
65    o Replacing delZ by delR in pkg/ctrl/
66    checkpoint51o_pre
67    
68    o undid all of cp51 pending some cleanups and discussion
69    o added the [#include "AD_CONFIG.h"] statement to all files that need
70       it for adjoint/tl #defines

167      of tracer Green's fucntions for ocean inversion project.
168    
169    checkpoint51f_pre
170    o Added on-the-fly spatial interpolation capability
171        "USE_EXF_INTERPOLATION" to pkg/exf.
172      - This is a temporary Cartesian-grid hack until
173        the super-duper ESMF coupler becomes available.
174      - See verification/global_with_exf/README for usage example.
175      - Removed obsolete EXFwindOnBgrid and SEAICEwindOnCgrid
176        flags and modified pkg/seaice accordingly.
177    o Bug fix to pkg/ptracers, pkg/generic_advdiff/gad_calc_rhs.F,

180    
181    checkpoint51e_post
182    o pkg/mom_vecinv:

198    o Use cluster local disks for purely local I/O
199      vs. globally visible disks needed for ctrl stuff
200      (merged from ecco-branch)
201      - new active_file_loc... and mdsio_..._loc routines
202      - affected packages: autodiff, ctrl, grdchk, mdsio

208      - debLevB: equivalent to current debugMode=.TRUE.
209    o introducing pathname variable mdsioLocalDir for mdsio
210      that can be specified at runtime
211      (relevant for cluster I/O to local disk)
212    `
213    >>>checkpoint51b_post
214    adjoint of ptracers
215    o disentangled ALLOW_PTRACERS using new ALLOW_GCHEM

229      - new pkgs: dic, gchem
230      - new subroutine in ptracers
231    o modify code for biogeo packages
232      - in model/src and pkg/ptracers
233    
234    checkpoint51
235    o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN
236      - autodiff, ctrl, exf, grdchk, seaice
237      kept separate packages
238      - cost, ecco, obcs
239    o updating verification/internal_wave, verification/lab_sea
240      (all verif's pass on faulks.lcs.mit.edu RH7.3, g77)
241    
242    checkpoint50i_post
243    o Preparing next differentiable checkpoint and sync
244      of MAIN vs. ecco-branch
245      - 1st step: this one is differentiable
246      - 2nd step: next(! not this) checkpoint will have updated packages
247                  from ecco-branch)
248    
249    checkpoint50h_post
250    o new package "land": provide surface BC for AIM.
251    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
252    o AIM: use true log-P extrapolation for near surface temp (= as in
253        F.Molteni paper) ; update aim.5l_cs output.
254    o New variable in PARM03 for more flexible pickups
255    o somewhat cleaned package initialisation sequence for
256      ctrl/ cost/ ecco/ in packages_... routines
257    
258    checkpoint50g_post
259    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
260      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
261      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
262        made the default because of faster convergence than ADI
263    
264    checkpoint50f_post
265    o exf totally restructured
266      - replaced all exf_set_ routines by one generic exf_set_gen.F
267        and made sure it's still differentiable
268      - split exf_getffields.F into new exf_bulkformulae.F
269      - exf_inscal_/exf_outscal_ suffixes consistent with field names

280     o removed lots of single quotes from comments
281    
282    checkpoint50e_post
283    o make KPP work with PTRACERS
284     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
285       nearly a copy of kpp_transport_s
286     - there is no analogue to SurfaceTendencyS, so I have to use
287       gPtr(of the surface layer) instead
288    o add a new platform SunFire+mpi (SunFire 15000) to genmake
289    checkpoint50e_pre
290    
291    checkpoint50d_post
292    o change kpp output from multiple-record state files to single-record state
293      files analogous to write_state.F
294    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
295      analogous to the cg2d-related output.
296    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
297      so that writing to internal file fn (with length 512) fails.
298    checkpoint50d_pre
299    
300    checkpoint50c_post
301    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
302    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
303    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
304    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
305    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
306    
307    checkpoint50c_pre
308    Merging from release1_p13:
309    o bug fix for pkg/seaice dynamic solver
310    o Added SEAICE_initialHEFF to pkg/seaice
311    
312    checkpoint50b_post
313    o store u*,v* in gU,V instead of in guNm1,gvNm1
314    o in order to put the momForcing out of the Adams-Bashforth:
315      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
316      to timestep.F
317    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
318    o re-generate output for highly sensitive test-exp:
319       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
320    
321    checkpoint50b_pre
322    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
323    o corrected CPP option mismatch in exf_Bulk... functions for case
324      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
325    
326    checkpoint50a_post
327    o Bug fix for merging between c50 and KPP.
328      ikey was passed from thermodynamics to kpp_calc via
329      common block rather than being recomputed in kpp_calc,
330      in contradiction with new key itdkey.
331      New key ikppkey created, and tamc.h headers updated.
332    
333    checkpoint50
334    - 2nd step of merge with ecco-branch:
335      merge changes in ecco-branch back into main trunk
336    - bug fix in find_alpha
337    - more storing in gmredi_calc_tensor.F, kpp_routines.F
338    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
339    - merged some sliced AD support routines
340    
341    checkpoint49
342    merged from ecco-branch:
343    o exf:
344      - Enable initialisation of forcing fields to constant
345        (runtime) values.
346      - in exf_getffields.F
347        Reduce i-/j-loop to interior domain, discarding overlaps.
348        That also fixes wrong TAF-key computations for key_1, key_2
349        with bulf formulae.
350      - exf_init.F modify #ifdef for exf_init_evap
351      - exf_getffieldrec.F, ctrl_getrec.F
352        The following INT-usages are not safe:
353          fldsecs  = int(fldsecs/fldperiod)*fldperiod
354          fldcount = int(fldsecs/fldperiod) + 1
355        and were modified.
356    o autodiff: checkpoint_lev...
357      - updated storing for bulk formulae (some arrays were missing)
358      - added state for seaice package
359      - synchronized with main branch
360    o DIVA:
361      Modif.s in
362      - the_main_loop.F
363      - the_model_main.F
364      and added cost_final_restore.F cost_final_store.F
365      o With these changes, it is possible to fully separate
366        the first forward run to compute the cost function (mdthe_main_loop)
367        and adjoint runs over individual DIVA intervals (adthe_main_loop)
368        into separate model executions.
369        This enables better tuning of DIVA to given queue sizes.
370      o Loss of cost function value in consecutive DIVA runs is
371        fixed by storing to 'costfinal' file.
372      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
373        beginning/end of adjoint integration is accounted for.
374      The current changes apply to TAF-1.4.26.
375      TAF has one remaining bug, requiring one manual change
376      (see MITgcm manual).
377    o cal: synchronized between MAIN and ecco-branch
378    
379    checkpoint48i_post
380    o Changes to restore differentiability of code w.r.t. previous tag
381      (mostly adding new routines to make list and replacing
382      pressure by totPhiHyd).
383    o Updated and merged grdchk package
384      - has both ADM and TLM checks
385      - works for single- and multi-proc.
386      - output cleaned
387      - worked successfully for parallel DIVA
388    o genmake:
389      - Adding -platform=SP4
390      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
391    o Modif. for DIVA:
392      ctrl_unpack should not be called in intermediate DIVA interval.
393      (similar thing would apply for active files such as
394      tbar, sbar, psbar, which should not be reinitialised;
395      only relevant for ecco-branch)
396    
397    checkpoint48h_post
398    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
399    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
400    o Added SEAICE_initialHEFF to pkg/seaice
401    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
402    
403    checkpoint48g_post
404    --- EOS:
405    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
406      store total Potential in totPhyHyd for diagnostics & EOS.
407    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
408    --- Pressure/geopotential gradient:
409    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
410    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
411      ( changes results of global_ocean_pressure )
412    o NLFS + z-coord.: add eta*Rho' contribution.
413    o accurate phiHyd when using interface-W at the middle between 2 centers
414     ( changes results of ideal_2D_oce )
415    o includes r* 2nd term in potential gradient.
416    
417    checkpoint48f_post
418    Merging from release1_p12:
419    o Modifications for using pkg/exf with pkg/seaice
420      - improved description of the various forcing configurations
421      - added basic radiation bulk formulae to pkg/exf
422      - units/sign fix for evap computation in exf_getffields.F
423      - updated verification/global_with_exf/results/output.txt
424    o Added pkg/sbo for computing IERS Special Bureau for the Oceans
425      (SBO) core products, including oceanic mass, center-of-mass,
426      angular, and bottom pressure (see pkg/sbo/README.sbo).
427    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
428      to avoid negative values in shallow regions.
429      - updated verification/natl_box/results/output.txt
430      - updated verification/lab_sea/results/output.txt
431    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
432    o Added useSingleCpuIO option (see PARAMS.h).
433    o Updated useSingleCpuIO option in mdsio_writefield.F to
434      work with multi-field files, e.g., for single-file pickup.
435    o pkg/seaice:
436      - bug fix in growth.F: QNET for no shortwave case
437      - added HeffFile for specifying initial sea-ice thickness
438      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
439    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
440      kpp_transport_t.F, forward_step.F, and the_main_loop.F
441    o pkg/seaice:
442      - adjoint-friendly modifications
443      - added a SEAICE_WRITE_PICKUP at end of the_model_main.F
444    
445    checkpoint48e_post
446    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
447    o dynamics: change definition of computational domain & adapt mom_fluxform
448      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
449    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
450        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
451        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
452        global_ocean.90x40x15 global_with_exf global_ocean_pressure
453        inverted_barometer solid-body.cs-32x32x1
454      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
455    
456    checkpoint48d_post
457    o in preparation for r*:
458     a) use pre-computed gradient of hydrostatic potential:
459        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
460     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
461        => affects results of glob_oce_pressure (different truncation error)  
462      update output.txt of ideal_2D_oce & global_ocean_pressure
463    
464    checkpoint48d_pre
465    o in preparation for r*:
466      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
467      pass the 2 comp. of the grad. as arguments to momentum S/R.
468      but for the moment, only used if it does not change the results.
469    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
