21    o updated the tiling for global_ocean_pressure
22    checkpoint52i_pre
23    
24    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of

42    checkpoint52f_pre
43    
44    checkpoint52e_post
45    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
46      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
47    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
48      to work with implicit vertical advection and AB ;
49    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.

64    o re-tiled many expts to allow comparison in multi-processor mode
65      - updated output accordingly
66      - changed hs94.128x64x5 to use intial T from file rather than use the
67        random number generator
68    o add infrastructure in model routines for fizhi and gridalt packages
69    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
70    o changes to permit hi-res, cubed-sphere, configuration
71      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
72      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
73      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
74        of surface winds for the cube
75      (A verification experiment, based on global_ocean.cs32x15, but with
76       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
77       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
78       complete with example surface forcing files and matlab scripts to look
79       at the output and compare it with that of global_ocean.cs32x15.)
80    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
81       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
82       to conform to the common rule.
83    o check-in the first version of the coupler + interfaces for multi-components
84       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
85       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
86       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
87       - ocean and atmos. share the same horizontal grid (no interpolation).
88       - exchanges between component and coupler is done in forward_step
89    o new verification experiment, cpl_aim+ocn:
90       coupled ocean - AIM atmosphere on cs32 grid.
91    
92    checkpoint52d_pre
93    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
94    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
95    
96    checkpoint52c_post
97    o Fixing OPTIONS files for use of exf:
98      - ALLOW_ECCO not needed
99      - ECCO_CPPOPTIONS.h should not be included from
100        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
101        as has been the case in the past
102      - All cal/exf related options are currently set in
103        single header file. Should remain so until we
104        agree on a consistent new policy.
105    o Removed all CPP options for cal package.
106      cal has no more CPP options.
107    o modified STOREs in GAD_ADVECTION
108    o corrected key comp. for passkey
109    
110    checkpoint52b_post
111    o new version: "thsice" of thermodynamic sea-ice pkg:
112     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
113     - modify fluxes but do not change theta directly;
114     - light cleaning of bulk_force pkg (still needed with thsice).
115     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
116       + output_thsice.txt to test thsice & bulk_force pkgs.
117    o put back grid & coriolis monitor output.
118    checkpoint52b_pre
119    
120    o call "do_the_model_io" at the beginning (=> dump initial state)
121    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
122    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
123      (need info on NUMBER_OF_PTRACERS)
124    o missing PTRACERS headers in some routines
125    o default tamc.h in pkg/autodiff supposed to crash
126      to ensure proper customization
127    
128    checkpoint52a_post
129    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
130      - moved surfaceTendencyTice from pkg/seaice to main code
131      - subroutine FREEZE_SURFACE now limits only surface temperature
132        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
133        => new output.txt for global_ocean.cs32x15 & global_with_exf
134      - keep the old version of FREEZE for backward compatibility;
135        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.

149    checkpoint51u_post
150    o this is the post-merge tag of the ecco-branch
151      (needs another clean checkout and re-testing)
152    o various natl_box_adjoint configs and results
153      but no input fields
154    o obcs adjoint not yet merged!
155    o adding ECCO global 1x1 and 2x2 degree configs
156    o updated/extended some store directives for seaice
157    o pkg/ecco now containes ecco-specific part of cost function
158    o top level routines the_main_loop, forward_step
159      supersede those in model/src/
160      previous input data.cost now in data.ecco
161      (new namelist ecco_cost_nml)
162    o in ctrl/ cleaned some cross-dependencies and updated CPP options
163    
164    checkpoint51t_post
165    o this is the pre-merge tag of the ecco-branch
166    
167    checkpoint51s_post

169    o pkg/grdchk
170      - renamed 'ph-grd 3' to 'grad-res'
171      - merged from ecco-branch
172        (remaining bug fixes for obcs gradient checks)
173      - additional high-precision output for testreport
174        (grep for 'precision_grdchk_result')
175    
176    checkpoint51r_post
177    o cleaned up or removed CPP_OPTIONS.h files
178    o updated results for some of the tests to reflect the new
179      optfiles (-ieee: -O0 instead of -O3)
180    
181    checkpoint51q_post
182    o cd_code:
183      - moved cd_scheme.F -> cd_code_scheme.F
184      - separate read_checkpoint from cd_code_ini_vars.F
185      - separated cd_code part from write_checkpoint

189    o ctrl package totally restructured
190      - pack/unpack now optional and decoupled from
191        xx_/adxx_ I/O

196    
197    checkpoint51p_post
198    o create initial cd_code package
199      - WARNING: the initialization of fields within packages
200        is broken because INI_FIELDS (where READ_CHECKPOINT is
201        called) is called *before* PACKAGES_INIT_VARIABLES.
202        This seems to be backwards since
203        1) its important to initially zero the entire field including
204           the "halo" region
205        2) zeroing needs to be done *before* reading pickup info
206           and the pickup call might or might not happen in any
207           particular run
208      - this needs an overhaul for R2
209    o cleanup verification/*/code/GMREDI_OPTIONS.h
210    o cleanup testreport

222      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
223        change rho -> rho-rhoConst
224      - replace call find_rho to find_rhonum

419    o AIM: use true log-P extrapolation for near surface temp (= as in
420        F.Molteni paper) ; update aim.5l_cs output.
421    o New variable in PARM03 for more flexible pickups
422    o somewhat cleaned package initialisation sequence for
423      ctrl/ cost/ ecco/ in packages_... routines
424    
425    checkpoint50g_post
426    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
427      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
428      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
429        made the default because of faster convergence than ADI
430    
431    checkpoint50f_post
432    o exf totally restructured
433      - replaced all exf_set_ routines by one generic exf_set_gen.F
434        and made sure it's still differentiable
435      - split exf_getffields.F into new exf_bulkformulae.F
436      - exf_inscal_/exf_outscal_ suffixes consistent with field names
437      - updated adjoint/makefile and relevant verif. accordingly
438    
439    checkpoint50f_pre
440     o AIM: near surface temp evaluated from Pot.Temp: fixed for Part Cell ;
441          + change Evap over land. (update aim.5l_cs output)
442     o added missing .cvsignores and made uniform across expts
443     o changed configuration of tidal_basin_2d expt
444     o added pkg/debug functions for tracing code in fatal crashes
445     o tidied pkg/monitor to use MONITOR_OPTIONS.h
446     o new fn in pkg/monitor to stop model if solution grows too big
447     o removed lots of single quotes from comments
448    
449    checkpoint50e_post
450    o make KPP work with PTRACERS
451     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
452       nearly a copy of kpp_transport_s
453     - there is no analogue to SurfaceTendencyS, so I have to use
454       gPtr(of the surface layer) instead
455    o add a new platform SunFire+mpi (SunFire 15000) to genmake
456    checkpoint50e_pre
457    
458    checkpoint50d_post
459    o change kpp output from multiple-record state files to single-record state
460      files analogous to write_state.F
461    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
462      analogous to the cg2d-related output.
463    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
464      so that writing to internal file fn (with length 512) fails.
465    checkpoint50d_pre
466    
467    checkpoint50c_post
468    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
469    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
470    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
471    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
472    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
473    
474    checkpoint50c_pre
475    Merging from release1_p13:
476    o bug fix for pkg/seaice dynamic solver
477    o Added SEAICE_initialHEFF to pkg/seaice
478    
479    checkpoint50b_post
480    o store u*,v* in gU,V instead of in guNm1,gvNm1
481    o in order to put the momForcing out of the Adams-Bashforth:
482      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
483      to timestep.F
484    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
485    o re-generate output for highly sensitive test-exp:
486       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
487    
488    checkpoint50b_pre
489    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
490    o corrected CPP option mismatch in exf_Bulk... functions for case
491      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
492    
493    checkpoint50a_post
494    o Bug fix for merging between c50 and KPP.
495      ikey was passed from thermodynamics to kpp_calc via
496      common block rather than being recomputed in kpp_calc,
497      in contradiction with new key itdkey.
498      New key ikppkey created, and tamc.h headers updated.
499    
500    checkpoint50
501    - 2nd step of merge with ecco-branch:
502      merge changes in ecco-branch back into main trunk
503    - bug fix in find_alpha
504    - more storing in gmredi_calc_tensor.F, kpp_routines.F
505    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
506    - merged some sliced AD support routines
507    
508  checkpoint49  checkpoint49
509    merged from ecco-branch:
510    o exf:
511      - Enable initialisation of forcing fields to constant
512        (runtime) values.
513      - in exf_getffields.F
514        Reduce i-/j-loop to interior domain, discarding overlaps.
515        That also fixes wrong TAF-key computations for key_1, key_2
516        with bulf formulae.
517      - exf_init.F modify #ifdef for exf_init_evap
518      - exf_getffieldrec.F, ctrl_getrec.F
519        The following INT-usages are not safe:
520          fldsecs  = int(fldsecs/fldperiod)*fldperiod
521          fldcount = int(fldsecs/fldperiod) + 1
522        and were modified.
523    o autodiff: checkpoint_lev...
524      - updated storing for bulk formulae (some arrays were missing)
525      - added state for seaice package
526      - synchronized with main branch
527    o DIVA:
528      Modif.s in
529      - the_main_loop.F
530      - the_model_main.F
531      and added cost_final_restore.F cost_final_store.F
532      o With these changes, it is possible to fully separate
533        the first forward run to compute the cost function (mdthe_main_loop)
534        and adjoint runs over individual DIVA intervals (adthe_main_loop)
535        into separate model executions.
536        This enables better tuning of DIVA to given queue sizes.
537      o Loss of cost function value in consecutive DIVA runs is
538        fixed by storing to 'costfinal' file.
539      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
540        beginning/end of adjoint integration is accounted for.
541      The current changes apply to TAF-1.4.26.
542      TAF has one remaining bug, requiring one manual change
543      (see MITgcm manual).
544    o cal: synchronized between MAIN and ecco-branch
545    
546    checkpoint48i_post
547  o Changes to restore differentiability of code w.r.t. previous tag  o Changes to restore differentiability of code w.r.t. previous tag
548    (mostly adding new routines to make list and replacing    (mostly adding new routines to make list and replacing
549    pressure by totPhiHyd).    pressure by totPhiHyd).
