3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    
6    o create initial cd_code package
7      - WARNING: the initialization of fields within packages
8        is broken because INI_FIELDS (where READ_CHECKPOINT is
9        called) is called *before* PACKAGES_INIT_VARIABLES.
10        This seems to be backwards since
11        1) its important to initially zero the entire field including
12           the "halo" region
13        2) zeroing needs to be done *before* reading pickup info
14           and the pickup call might or might not happen in any
15           particular run
16      - this needs an overhaul for R2
17    o cleanup verification/*/code/GMREDI_OPTIONS.h
18    o cleanup testreport
19    
20    checkpoint51o_post
21    o bringing AD-related verif's up to date with genmake2

27    o cleaning ALLOW_GRADIENT_CHECK -> ALLOW_GRDCHK
28    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
29    o bug fix in find_alpha.F for MDJWF:
30      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
31        change rho -> rho-rhoConst
32      - replace call find_rho to find_rhonum
33    o initialisation of rFlx extended to full array (required by TAF)
34      and shifted to thermodynamics
35    o removed PTRACERS.h in ptracers routine
36    o added surfacetendencyPtr to S/R parameter list pracers_forcing
37    o Correcting initialisations for fVerU, fVerV.

43    o undid all of cp51 pending some cleanups and discussion
44    o added the [#include "AD_CONFIG.h"] statement to all files that need
45       it for adjoint/tl #defines
46     o re-worked the build logic in genmake2 to support AD_CONFIG.h
47     o removed tools/genmake since it no longer works

89     - new output.txt for idealized oceanic exp (NHMTerms are now turned off):
90        exp1, ideal_2D_oce
91     - change data file of oceanic exp (leave the results unchanged for now)
92       exp2, global_ocean[90x40x15,pressure,with_exf], lab_sea, natl_box
93    o set gravitySign automatically according to the vertical coordinate used
94      (and change sign: back to "logical" value: +1 when R increases downward)

143    
144    checkpoint51f_pre
145    o Added on-the-fly spatial interpolation capability
146        "USE_EXF_INTERPOLATION" to pkg/exf.
147      - This is a temporary Cartesian-grid hack until
148        the super-duper ESMF coupler becomes available.
149      - See verification/global_with_exf/README for usage example.
150      - Removed obsolete EXFwindOnBgrid and SEAICEwindOnCgrid
151        flags and modified pkg/seaice accordingly.

155    
156    checkpoint51e_post

170    o modif's to restore TAMC compatibility
171      - avoid "_d" constructs in PARAMETER declarations
172      - avoid interrupting lines by comment lines
173    o Use cluster local disks for purely local I/O
174      vs. globally visible disks needed for ctrl stuff
175      (merged from ecco-branch)
176      - new active_file_loc... and mdsio_..._loc routines
177      - affected packages: autodiff, ctrl, grdchk, mdsio

180    o introducing integer flag debugLevel
181      - debLevZero: suppress all output
182      - debLevA: standard
183      - debLevB: equivalent to current debugMode=.TRUE.
184    o introducing pathname variable mdsioLocalDir for mdsio
185      that can be specified at runtime
186      (relevant for cluster I/O to local disk)
187    `
188    >>>checkpoint51b_post
189    adjoint of ptracers
190    o disentangled ALLOW_PTRACERS using new ALLOW_GCHEM

206    o modify code for biogeo packages
207      - in model/src and pkg/ptracers
208    
209    checkpoint51
210    o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN
211      - autodiff, ctrl, exf, grdchk, seaice
212      kept separate packages
213      - cost, ecco, obcs
214    o updating verification/internal_wave, verification/lab_sea
215      (all verif's pass on faulks.lcs.mit.edu RH7.3, g77)
216    
217    checkpoint50i_post
218    o Preparing next differentiable checkpoint and sync
219      of MAIN vs. ecco-branch
220      - 1st step: this one is differentiable
221      - 2nd step: next(! not this) checkpoint will have updated packages
222                  from ecco-branch)
223    
224    checkpoint50h_post
225    o new package "land": provide surface BC for AIM.
226    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
227    o AIM: use true log-P extrapolation for near surface temp (= as in
228        F.Molteni paper) ; update aim.5l_cs output.
229    o New variable in PARM03 for more flexible pickups
230    o somewhat cleaned package initialisation sequence for
231      ctrl/ cost/ ecco/ in packages_... routines
232    
233    checkpoint50g_post
234    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
235      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
236      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
237        made the default because of faster convergence than ADI
238    
239    checkpoint50f_post
240    o exf totally restructured
241      - replaced all exf_set_ routines by one generic exf_set_gen.F
242        and made sure it's still differentiable
243      - split exf_getffields.F into new exf_bulkformulae.F

255     o removed lots of single quotes from comments
256    
257    checkpoint50e_post
258    o make KPP work with PTRACERS
259     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
260       nearly a copy of kpp_transport_s
261     - there is no analogue to SurfaceTendencyS, so I have to use
262       gPtr(of the surface layer) instead
263    o add a new platform SunFire+mpi (SunFire 15000) to genmake
264    checkpoint50e_pre
265    
266    checkpoint50d_post
267    o change kpp output from multiple-record state files to single-record state
268      files analogous to write_state.F
269    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
270      analogous to the cg2d-related output.
271    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
272      so that writing to internal file fn (with length 512) fails.
273    checkpoint50d_pre
274    
275    checkpoint50c_post
276    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
277    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
278    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
279    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
280    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
281    
282    checkpoint50c_pre
283    Merging from release1_p13:
284    o bug fix for pkg/seaice dynamic solver
285    o Added SEAICE_initialHEFF to pkg/seaice
286    
287    checkpoint50b_post
288    o store u*,v* in gU,V instead of in guNm1,gvNm1
289    o in order to put the momForcing out of the Adams-Bashforth:
290      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
291      to timestep.F
292    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
293    o re-generate output for highly sensitive test-exp:
294       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
295    
296    checkpoint50b_pre
297    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
298    o corrected CPP option mismatch in exf_Bulk... functions for case
299      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
300    
301    checkpoint50a_post
302    o Bug fix for merging between c50 and KPP.
303      ikey was passed from thermodynamics to kpp_calc via
304      common block rather than being recomputed in kpp_calc,
305      in contradiction with new key itdkey.
306      New key ikppkey created, and tamc.h headers updated.
307    
308    checkpoint50
309    - 2nd step of merge with ecco-branch:
310      merge changes in ecco-branch back into main trunk
311    - bug fix in find_alpha
312    - more storing in gmredi_calc_tensor.F, kpp_routines.F
313    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
314    - merged some sliced AD support routines
315    
316    checkpoint49
317    merged from ecco-branch:
318    o exf:
319      - Enable initialisation of forcing fields to constant
320        (runtime) values.
321      - in exf_getffields.F
322        Reduce i-/j-loop to interior domain, discarding overlaps.
323        That also fixes wrong TAF-key computations for key_1, key_2
324        with bulf formulae.
325      - exf_init.F modify #ifdef for exf_init_evap
326      - exf_getffieldrec.F, ctrl_getrec.F
327        The following INT-usages are not safe:
328          fldsecs  = int(fldsecs/fldperiod)*fldperiod
329          fldcount = int(fldsecs/fldperiod) + 1
330        and were modified.
331    o autodiff: checkpoint_lev...
332      - updated storing for bulk formulae (some arrays were missing)
333      - added state for seaice package
334      - synchronized with main branch
335    o DIVA:
336      Modif.s in
337      - the_main_loop.F
338      - the_model_main.F
339      and added cost_final_restore.F cost_final_store.F
340      o With these changes, it is possible to fully separate
341        the first forward run to compute the cost function (mdthe_main_loop)
342        and adjoint runs over individual DIVA intervals (adthe_main_loop)
343        into separate model executions.
344        This enables better tuning of DIVA to given queue sizes.
345      o Loss of cost function value in consecutive DIVA runs is
346        fixed by storing to 'costfinal' file.
347      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
348        beginning/end of adjoint integration is accounted for.
349      The current changes apply to TAF-1.4.26.
350      TAF has one remaining bug, requiring one manual change
351      (see MITgcm manual).
352    o cal: synchronized between MAIN and ecco-branch
353    
354    checkpoint48i_post
355    o Changes to restore differentiability of code w.r.t. previous tag
356      (mostly adding new routines to make list and replacing
357      pressure by totPhiHyd).
358    o Updated and merged grdchk package
359      - has both ADM and TLM checks
360      - works for single- and multi-proc.
361      - output cleaned
362      - worked successfully for parallel DIVA
363    o genmake:
364      - Adding -platform=SP4
365      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
366    o Modif. for DIVA:
367      ctrl_unpack should not be called in intermediate DIVA interval.
368      (similar thing would apply for active files such as
369      tbar, sbar, psbar, which should not be reinitialised;
370      only relevant for ecco-branch)
371    
372    checkpoint48h_post
373    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
374    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
375    o Added SEAICE_initialHEFF to pkg/seaice
376    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
377    
378    checkpoint48g_post
379    --- EOS:
380    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
381      store total Potential in totPhyHyd for diagnostics & EOS.
382    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
383    --- Pressure/geopotential gradient:
384    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
385    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
386      ( changes results of global_ocean_pressure )
387    o NLFS + z-coord.: add eta*Rho' contribution.
388    o accurate phiHyd when using interface-W at the middle between 2 centers
389     ( changes results of ideal_2D_oce )
390    o includes r* 2nd term in potential gradient.
391    
392    checkpoint48f_post
393    Merging from release1_p12:
394    o Modifications for using pkg/exf with pkg/seaice

397      - units/sign fix for evap computation in exf_getffields.F
398      - updated verification/global_with_exf/results/output.txt
399    o Added pkg/sbo for computing IERS Special Bureau for the Oceans
400      (SBO) core products, including oceanic mass, center-of-mass,
401      angular, and bottom pressure (see pkg/sbo/README.sbo).
402    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
403      to avoid negative values in shallow regions.
404      - updated verification/natl_box/results/output.txt
405      - updated verification/lab_sea/results/output.txt
406    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
407    o Added useSingleCpuIO option (see PARAMS.h).
408    o Updated useSingleCpuIO option in mdsio_writefield.F to
409      work with multi-field files, e.g., for single-file pickup.
410    o pkg/seaice:
411      - bug fix in growth.F: QNET for no shortwave case
412      - added HeffFile for specifying initial sea-ice thickness
413      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
414    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
415      kpp_transport_t.F, forward_step.F, and the_main_loop.F
416    o pkg/seaice:
417      - adjoint-friendly modifications
418      - added a SEAICE_WRITE_PICKUP at end of the_model_main.F
419    
420    checkpoint48e_post
421    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
422    o dynamics: change definition of computational domain & adapt mom_fluxform
423      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
424    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
425        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
426        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
427        global_ocean.90x40x15 global_with_exf global_ocean_pressure
428        inverted_barometer solid-body.cs-32x32x1
429      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
430    
431    checkpoint48d_post
432    o in preparation for r*:
433     a) use pre-computed gradient of hydrostatic potential:
434        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
435     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
436        => affects results of glob_oce_pressure (different truncation error)  
437      update output.txt of ideal_2D_oce & global_ocean_pressure
438    
439    checkpoint48d_pre
440    o in preparation for r*:
441      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
442      pass the 2 comp. of the grad. as arguments to momentum S/R.
443      but for the moment, only used if it does not change the results.
444    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
445    
446    checkpoint48c_post
447    Modifications in treatment of initial flux forcing controls
448    to avoid extra storing of flux fields.
449    
450    checkpoint48c_pre
451    o Added tidal_basin_2d experiment (currently 1D!)
452    o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented)
453    
454    checkpoint48b_post
455    o r* coordinate added in #ifdef NONLIN_FRSURF block.
456     (modification to pressure gradient not yet implemented)
457    o mom_fluxform: new S/R mom_calc_rtrans.F computes vertical transports
458      (for U & V) that are used for vertical advection of momentum.
459    
460    checkpoint48a_post
461    o In preparation for r*, use temp. array to compute vertical transport
462       in flux-form momentum pkg. => change results of few test-exp.
463      Update output of: exp4, exp5, front_relax, global_ocean_pressure,
464                        lab_sea, natl_box & plume_on_slope
465    
466  checkpoint48  checkpoint48
467  o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D')  o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D')
