3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    o MNC:
6      - make myThid the last argument for all subroutines
7      - new default for the grid files: NO halos
8      - add useMNC run-time flag
9    o thermodynamics sea-ice (thsice) is now tested with testreport.
10    o test exp. advect_cs: use the standard cs32 grid ; update output.
11    
12  untagged  checkpoint52l_post
13    o new land formulation:
14      a) use ground enthalpy as prognostic variable to ensure exact
15         energy conservation.
16      b) account for water temperature and for latent heat of freezing
17         in all processes (rain, run-off, ground storage)
18      c) compute surface and ground temperature implicitly.
19    o aim_v23 modification for new land model:
20      a) Treat separately land / ocean / sea-ice surface fluxes
21         to allow implicit computation of land & sea-ice surface temp.
22      b) add snow precipitation.
23    checkpoint52l_pre
24    
25    o fix problem (when 1 tile is empty) in min/max monitor.
26    o fix bug in timeAve (u,vZetatave in common block)
27    o no restoring terms under ice for pkg/seaice
28    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
29    o bug fix for pkg/seaice pickups
30    o change MNC call locations and add coordinate attributes
31    o mask vorticity at the corner ; affects global_ocean.cs output
32    o fix ini_curvilinear_grid ; test CS experiments with mpi
33    o aim.5l_cs: modify sea-ice fraction input file ; update output
34    o exf: Adding simple range check routine for exf fields after read
35    
36    checkpoint52k_post
37    o removed top-level directory "diags"
38      - we migrated these functions to pkg/timeave a long time ago
39    o fixed bug introduced in pkg/monitor
40    o accuracy ctrlprec = 32 insuffient for gradient checks using
41      averaged fields (I/O via cost_averages)
42      -> use ctrl.h in active_file*.F to control I/O precision.
43    o paramter list of CALL ADTHE_MAIN_LOOP
44    o added initial do_the_model_io to ecco
45    o set all ...Freq to zero after cost_final

48    
49    checkpoint52j_post
50    o fix nchklev in tamc.h for global_ocean...
51    o Bringing flow and store directives up-to-date
52    o Really weird thing!
53      call do_the_model_io from the_main_loop with parameters
54      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
55      TAF places a faulty re-call of initialise_varia
56      after cost_final call which should not be there!
57    checkpoint52j_pre
58    
59    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
60      error messages
61    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
62    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating

65    o update AIM Cubed-Sphere exp (aim.5l_cs):
66      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
67    o update AIM Equatorial Channel exp:
68      use standard aim_v23 pkg and change the SST fields to be more realistic.
69    o globalFile now works with exch2
70    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
71      mon_vort3.F to make exch2 friendly with >1 tile per cube face

76    o updated the tiling for global_ocean_pressure
77    checkpoint52i_pre
78    
79    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
80      the old pkg/aim).
81    
82    checkpoint52h_pre
83    o shortened offending lines in exch2_send_rx?.template
84    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
85    o genmake2: add build & execute test for NetCDF code
86    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
87      old grid files, moved CPP_EEMACROS.h to pkg/exch2
88    o added useSingleCPUIO flag to monitor.F and mon_out.F
89    o added temporary hack for sea-ice dynamics on the cube:
90      metric terms are ignored and it is assumed that
91      there is no sea-ice on cube faces 1, 2, 4, and 5.
92    
93    checkpoint52f_post
94    o added exch2 cube routines to pkg/exch2
95    o modified hs94.cs-32x32x5 to use it
96    o added new grid files to hs94.cs-32x32x5
97    checkpoint52f_pre
98    
99    checkpoint52e_post
100    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
101      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
102    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
103      to work with implicit vertical advection and AB ;
104    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
105    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
106     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
107    checkpoint52e_pre
108    
109    o fix bug in impldiff when Nr=1 or Nr=2.
110    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
111    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
112    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
113      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure

117    
118    checkpoint52d_post
119    o re-tiled many expts to allow comparison in multi-processor mode
120      - updated output accordingly
121      - changed hs94.128x64x5 to use intial T from file rather than use the
122        random number generator
123    o add infrastructure in model routines for fizhi and gridalt packages
124    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
125    o changes to permit hi-res, cubed-sphere, configuration
126      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
127      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
128      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
129        of surface winds for the cube
130      (A verification experiment, based on global_ocean.cs32x15, but with
131       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
132       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
133       complete with example surface forcing files and matlab scripts to look
134       at the output and compare it with that of global_ocean.cs32x15.)
135    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
136       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
137       to conform to the common rule.
138    o check-in the first version of the coupler + interfaces for multi-components
139       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
140       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
141       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
142       - ocean and atmos. share the same horizontal grid (no interpolation).
143       - exchanges between component and coupler is done in forward_step
144    o new verification experiment, cpl_aim+ocn:
145       coupled ocean - AIM atmosphere on cs32 grid.
146    
147    checkpoint52d_pre
148    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
149    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
150    
151    checkpoint52c_post
152    o Fixing OPTIONS files for use of exf:
153      - ALLOW_ECCO not needed
154      - ECCO_CPPOPTIONS.h should not be included from
155        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
156        as has been the case in the past
157      - All cal/exf related options are currently set in
158        single header file. Should remain so until we
159        agree on a consistent new policy.
160    o Removed all CPP options for cal package.
161      cal has no more CPP options.
162    o modified STOREs in GAD_ADVECTION
163    o corrected key comp. for passkey
164    
165    checkpoint52b_post
166    o new version: "thsice" of thermodynamic sea-ice pkg:
167     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
168     - modify fluxes but do not change theta directly;
169     - light cleaning of bulk_force pkg (still needed with thsice).
170     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
171       + output_thsice.txt to test thsice & bulk_force pkgs.
172    o put back grid & coriolis monitor output.
173    checkpoint52b_pre
174    
175    o call "do_the_model_io" at the beginning (=> dump initial state)
176    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
177    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
178      (need info on NUMBER_OF_PTRACERS)
179    o missing PTRACERS headers in some routines
180    o default tamc.h in pkg/autodiff supposed to crash
181      to ensure proper customization
182    
183    checkpoint52a_post
184    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
185      - moved surfaceTendencyTice from pkg/seaice to main code
186      - subroutine FREEZE_SURFACE now limits only surface temperature
187        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
188        => new output.txt for global_ocean.cs32x15 & global_with_exf
189      - keep the old version of FREEZE for backward compatibility;
190        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
191      - corresponding modifs for TAF directives
192    o added surface flux output variables to TIMEAVE_STATVARS

202    o after testing adjoints of checkpoint51u_post
203    
204    checkpoint51u_post
205    o this is the post-merge tag of the ecco-branch
206      (needs another clean checkout and re-testing)
207    o various natl_box_adjoint configs and results
208      but no input fields
209    o obcs adjoint not yet merged!
210    o adding ECCO global 1x1 and 2x2 degree configs
211    o updated/extended some store directives for seaice
212    o pkg/ecco now containes ecco-specific part of cost function
213    o top level routines the_main_loop, forward_step
214      supersede those in model/src/
215      previous input data.cost now in data.ecco
216      (new namelist ecco_cost_nml)
217    o in ctrl/ cleaned some cross-dependencies and updated CPP options
218    
219    checkpoint51t_post
220    o this is the pre-merge tag of the ecco-branch
221    
222    checkpoint51s_post
223    o cleanup: removed various obsolete #define-s
224    o pkg/grdchk
225      - renamed 'ph-grd 3' to 'grad-res'
226      - merged from ecco-branch
227        (remaining bug fixes for obcs gradient checks)
228      - additional high-precision output for testreport
229        (grep for 'precision_grdchk_result')
230    
231    checkpoint51r_post
232    o cleaned up or removed CPP_OPTIONS.h files
233    o updated results for some of the tests to reflect the new
234      optfiles (-ieee: -O0 instead of -O3)
235    
236    checkpoint51q_post
237    o cd_code:
238      - moved cd_scheme.F -> cd_code_scheme.F
239      - separate read_checkpoint from cd_code_ini_vars.F
240      - separated cd_code part from write_checkpoint
241      - updated AD_SOURCE, generated .flow
242      - added CD_CODE_VARS.h to the_main_loop
243      - Moving cd_code specific store dir.s to pkg/cd_code
244    o ctrl package totally restructured
245      - pack/unpack now optional and decoupled from
246        xx_/adxx_ I/O
247      - ctrl_pack/unpack cleaned

249      - confined inclusion of AD_CONFIG.h to where necessary.
250    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
251    
252    checkpoint51p_post
253    o create initial cd_code package
254      - WARNING: the initialization of fields within packages
255        is broken because INI_FIELDS (where READ_CHECKPOINT is
256        called) is called *before* PACKAGES_INIT_VARIABLES.
257        This seems to be backwards since
258        1) its important to initially zero the entire field including
259           the "halo" region
260        2) zeroing needs to be done *before* reading pickup info
261           and the pickup call might or might not happen in any
262           particular run
263      - this needs an overhaul for R2
264    o cleanup verification/*/code/GMREDI_OPTIONS.h
265    o cleanup testreport
266    
267    checkpoint51o_post
268    o bringing AD-related verif's up to date with genmake2

272      - (front_relax/ )
273    o (more) consistent directory structure for AD-related verif.'s
274    o cleaning ALLOW_GRADIENT_CHECK -> ALLOW_GRDCHK
275    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
276    o bug fix in find_alpha.F for MDJWF:
277      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
278        change rho -> rho-rhoConst
279      - replace call find_rho to find_rhonum
280    o initialisation of rFlx extended to full array (required by TAF)
281      and shifted to thermodynamics
282    o removed PTRACERS.h in ptracers routine
283    o added surfacetendencyPtr to S/R parameter list pracers_forcing
284    o Correcting initialisations for fVerU, fVerV.
285    o helping TAF to recognize dependency on kUp for
286      fVerU, fVerV

298      - moved surfaceTendencyTice from pkg/seaice to main code
299      - FREEZE & EXTERNAL_FORCING_SURF moved to FORWARD_STEP
300      - subroutine FREEZE now limits only surface temperature
301        (this means new output.txt for global_ocean.90x40x15,
302         global_ocean.cs32x15, and global_with_exf)
303    o added surface flux output variables to TIMEAVE_STATVARS
304    
305    checkpoint51n_pre
306    o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F

326    checkpoint51l_pre
327    o add salt flux to forcing fields (used when salty sea-ice forms or melts)
328    o enable to apply restoring on S & T only in a latitude band.
329    o update output (external_forcing_surf modif. change truncation errors)
330       global_ocean.cs32x15, global_ocean_pressure, lab_sea, natl_box
331    
332    checkpoint51k_post
333    o change default to: useNHMTerms=.FALSE.
334     - new output.txt for atmos. exp (NHMTerms were wrong but now turned off):
335       adjustment.128x64x1, aim.5l_Eq_Ch, aim.5l_LatLon, hs94.128x64x5, hs94.1x64x5

359    
360    checkpoint51i_post
361    o merge of the branch-genmake2

415      (instead of the string length) when the string. char is empty
416    o fix bug in dxV,dyU definition of cubed-sphere grid (ini_curvilinear_grid)
417    o modif's to restore TAMC compatibility
418      - avoid "_d" constructs in PARAMETER declarations
419      - avoid interrupting lines by comment lines
420    o Use cluster local disks for purely local I/O
421      vs. globally visible disks needed for ctrl stuff
422      (merged from ecco-branch)
423      - new active_file_loc... and mdsio_..._loc routines
424      - affected packages: autodiff, ctrl, grdchk, mdsio
425    
426    checkpoint51c_post
427    o introducing integer flag debugLevel
428      - debLevZero: suppress all output
429      - debLevA: standard
430      - debLevB: equivalent to current debugMode=.TRUE.
431    o introducing pathname variable mdsioLocalDir for mdsio
432      that can be specified at runtime
433      (relevant for cluster I/O to local disk)
434    `
435    >>>checkpoint51b_post
436    adjoint of ptracers
437    o disentangled ALLOW_PTRACERS using new ALLOW_GCHEM
438    o extended state in checkpoint_lev?, etc.
439    o alternative ctrl/cost with tr1 or ptracer
440    o new comlev1_bibj_ptracers
441    o new ptracers.flow
442    o made ptracers_forcing same as external_forcing_s
443    o added verification for adjoint with ptracers
444      - adm. grdchk fail so far
445      - tlm. grdchk OK
446      - checked tapelev/comlev recomputations: OK
447    <<<checkpoint51b_pre
448    
449    checkpoint51a_post
450    o added code for biogeochemistry package
451      - new pkgs: dic, gchem
452      - new subroutine in ptracers
453    o modify code for biogeo packages
454      - in model/src and pkg/ptracers
455    
456    checkpoint51
457    o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN
458      - autodiff, ctrl, exf, grdchk, seaice
459      kept separate packages
460      - cost, ecco, obcs
461    o updating verification/internal_wave, verification/lab_sea
462      (all verif's pass on faulks.lcs.mit.edu RH7.3, g77)
463    
464    checkpoint50i_post
465    o Preparing next differentiable checkpoint and sync
466      of MAIN vs. ecco-branch
467      - 1st step: this one is differentiable
468      - 2nd step: next(! not this) checkpoint will have updated packages
469                  from ecco-branch)
470    
471    checkpoint50h_post
472    o new package "land": provide surface BC for AIM.
473    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
474    o AIM: use true log-P extrapolation for near surface temp (= as in
475        F.Molteni paper) ; update aim.5l_cs output.
476    o New variable in PARM03 for more flexible pickups
477    o somewhat cleaned package initialisation sequence for
478      ctrl/ cost/ ecco/ in packages_... routines
479    
480    checkpoint50g_post
481    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
482      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
483      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
484        made the default because of faster convergence than ADI
485    
486    checkpoint50f_post
487    o exf totally restructured
488      - replaced all exf_set_ routines by one generic exf_set_gen.F
489        and made sure it's still differentiable
490      - split exf_getffields.F into new exf_bulkformulae.F
491      - exf_inscal_/exf_outscal_ suffixes consistent with field names
492      - updated adjoint/makefile and relevant verif. accordingly
493    
494    checkpoint50f_pre
495     o AIM: near surface temp evaluated from Pot.Temp: fixed for Part Cell ;
496          + change Evap over land. (update aim.5l_cs output)
497     o added missing .cvsignores and made uniform across expts
498     o changed configuration of tidal_basin_2d expt
499     o added pkg/debug functions for tracing code in fatal crashes
500     o tidied pkg/monitor to use MONITOR_OPTIONS.h
501     o new fn in pkg/monitor to stop model if solution grows too big
502     o removed lots of single quotes from comments
503    
504    checkpoint50e_post
505    o make KPP work with PTRACERS
506     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
507       nearly a copy of kpp_transport_s
508     - there is no analogue to SurfaceTendencyS, so I have to use
509       gPtr(of the surface layer) instead
510    o add a new platform SunFire+mpi (SunFire 15000) to genmake
511    checkpoint50e_pre
512    
513    checkpoint50d_post
514    o change kpp output from multiple-record state files to single-record state
515      files analogous to write_state.F
516    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
517      analogous to the cg2d-related output.
518    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
519      so that writing to internal file fn (with length 512) fails.
520    checkpoint50d_pre
521    
522    checkpoint50c_post
523    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
524    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
525    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
526    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
527    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
528    
529    checkpoint50c_pre
530    Merging from release1_p13:
531    o bug fix for pkg/seaice dynamic solver
532    o Added SEAICE_initialHEFF to pkg/seaice
533    
534    checkpoint50b_post
535    o store u*,v* in gU,V instead of in guNm1,gvNm1
536    o in order to put the momForcing out of the Adams-Bashforth:
537      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
538      to timestep.F
539    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
540    o re-generate output for highly sensitive test-exp:
541       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
542    
543    checkpoint50b_pre
544    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
545    o corrected CPP option mismatch in exf_Bulk... functions for case
546      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
547    
548    checkpoint50a_post
549    o Bug fix for merging between c50 and KPP.
550      ikey was passed from thermodynamics to kpp_calc via
551      common block rather than being recomputed in kpp_calc,
552      in contradiction with new key itdkey.
553      New key ikppkey created, and tamc.h headers updated.
554    
555    checkpoint50
556    - 2nd step of merge with ecco-branch:
557      merge changes in ecco-branch back into main trunk
558    - bug fix in find_alpha
559    - more storing in gmredi_calc_tensor.F, kpp_routines.F
560    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
561    - merged some sliced AD support routines
562    
563    checkpoint49
564    merged from ecco-branch:
565    o exf:
566      - Enable initialisation of forcing fields to constant
567        (runtime) values.
568      - in exf_getffields.F
569        Reduce i-/j-loop to interior domain, discarding overlaps.
570        That also fixes wrong TAF-key computations for key_1, key_2
571        with bulf formulae.
572      - exf_init.F modify #ifdef for exf_init_evap
573      - exf_getffieldrec.F, ctrl_getrec.F
574        The following INT-usages are not safe:
575          fldsecs  = int(fldsecs/fldperiod)*fldperiod
576          fldcount = int(fldsecs/fldperiod) + 1
577        and were modified.
578    o autodiff: checkpoint_lev...
579      - updated storing for bulk formulae (some arrays were missing)
580      - added state for seaice package
581      - synchronized with main branch
582    o DIVA:
583      Modif.s in
584      - the_main_loop.F
585      - the_model_main.F
586      and added cost_final_restore.F cost_final_store.F
587      o With these changes, it is possible to fully separate
588        the first forward run to compute the cost function (mdthe_main_loop)
589        and adjoint runs over individual DIVA intervals (adthe_main_loop)
590        into separate model executions.
591        This enables better tuning of DIVA to given queue sizes.
592      o Loss of cost function value in consecutive DIVA runs is
593        fixed by storing to 'costfinal' file.
594      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
595        beginning/end of adjoint integration is accounted for.
596      The current changes apply to TAF-1.4.26.
597      TAF has one remaining bug, requiring one manual change
598      (see MITgcm manual).
599    o cal: synchronized between MAIN and ecco-branch
600    
601    checkpoint48i_post
602    o Changes to restore differentiability of code w.r.t. previous tag
603      (mostly adding new routines to make list and replacing
604      pressure by totPhiHyd).
605    o Updated and merged grdchk package
606      - has both ADM and TLM checks
607      - works for single- and multi-proc.
608      - output cleaned
609      - worked successfully for parallel DIVA
610    o genmake:
611      - Adding -platform=SP4
612      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
613    o Modif. for DIVA:
614      ctrl_unpack should not be called in intermediate DIVA interval.
615      (similar thing would apply for active files such as
616      tbar, sbar, psbar, which should not be reinitialised;
617      only relevant for ecco-branch)
618    
619    checkpoint48h_post
620  o improve "ini_p_ground" when using finite difference form for calc_phi_hyd  o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
621  o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F  o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
622  o Added SEAICE_initialHEFF to pkg/seaice  o Added SEAICE_initialHEFF to pkg/seaice
623    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
