4      ==============================      ==============================
5    
6    checkpoint52l_pre
7    
8    o fix problem (when 1 tile is empty) in min/max monitor.
9    o fix bug in timeAve (u,vZetatave in common block)
10    o no restoring terms under ice for pkg/seaice
11    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
12    o bug fix for pkg/seaice pickups
13    o change MNC call locations and add coordinate attributes
14    o mask vorticity at the corner ; affects global_ocean.cs output
15    o fix ini_curvilinear_grid ; test CS experiments with mpi
16    o aim.5l_cs: modify sea-ice fraction input file ; update output
17    o exf: Adding simple range check routine for exf fields after read
18    
19    checkpoint52k_post
20    o removed top-level directory "diags"
21      - we migrated these functions to pkg/timeave a long time ago
22    o fixed bug introduced in pkg/monitor
23    o accuracy ctrlprec = 32 insuffient for gradient checks using
24      averaged fields (I/O via cost_averages)
25      -> use ctrl.h in active_file*.F to control I/O precision.
26    o paramter list of CALL ADTHE_MAIN_LOOP
27    o added initial do_the_model_io to ecco
28    o set all ...Freq to zero after cost_final
29      taveFreq, dumpFreq, pChkptFreq
30    o MAIN and ECCO differentiability restored
31    
32    checkpoint52j_post
33    o fix nchklev in tamc.h for global_ocean...
34    o Bringing flow and store directives up-to-date
35    o Really weird thing!
36      call do_the_model_io from the_main_loop with parameters
37      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
38      TAF places a faulty re-call of initialise_varia
39      after cost_final call which should not be there!
40    checkpoint52j_pre
41    
42    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
43      error messages
44    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
45    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
46      debug output
47    o modfied mdsio_writefield.F to handle non-global files under exch2
48    o update AIM Cubed-Sphere exp (aim.5l_cs):
49      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
50    o update AIM Equatorial Channel exp:
51      use standard aim_v23 pkg and change the SST fields to be more realistic.
52    o globalFile now works with exch2
53    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
54      mon_vort3.F to make exch2 friendly with >1 tile per cube face
55    o limit timeave output for hi-res integrations
56    
57    checkpoint52i_post
58    o removed CPP_EEOPTIONS.h from verification/*/code
59    o updated the tiling for global_ocean_pressure
60    checkpoint52i_pre
61    
62    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
63      the old pkg/aim).
64    
65    checkpoint52h_pre
66    o shortened offending lines in exch2_send_rx?.template
67    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
68    o genmake2: add build & execute test for NetCDF code
69    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
70      old grid files, moved CPP_EEMACROS.h to pkg/exch2
71    o added useSingleCPUIO flag to monitor.F and mon_out.F
72    o added temporary hack for sea-ice dynamics on the cube:
73      metric terms are ignored and it is assumed that
74      there is no sea-ice on cube faces 1, 2, 4, and 5.
75    
76    checkpoint52f_post
77    o added exch2 cube routines to pkg/exch2
78    o modified hs94.cs-32x32x5 to use it
79    o added new grid files to hs94.cs-32x32x5
80    checkpoint52f_pre
81    
82    checkpoint52e_post
83    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
84      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
85    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
86      to work with implicit vertical advection and AB ;
87    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
88    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
89     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
90    checkpoint52e_pre
91    
92    o fix bug in impldiff when Nr=1 or Nr=2.
93    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
94    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
95    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
96      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
97    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
98    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
99    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
100    
101    checkpoint52d_post
102    o re-tiled many expts to allow comparison in multi-processor mode
103      - updated output accordingly
104      - changed hs94.128x64x5 to use intial T from file rather than use the
105        random number generator
106    o add infrastructure in model routines for fizhi and gridalt packages
107    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
108    o changes to permit hi-res, cubed-sphere, configuration
109      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
110      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
111      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
112        of surface winds for the cube
113      (A verification experiment, based on global_ocean.cs32x15, but with
114       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
115       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
116       complete with example surface forcing files and matlab scripts to look
117       at the output and compare it with that of global_ocean.cs32x15.)
118    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
119       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
120       to conform to the common rule.
121    o check-in the first version of the coupler + interfaces for multi-components
122       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
123       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
124       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
125       - ocean and atmos. share the same horizontal grid (no interpolation).
126       - exchanges between component and coupler is done in forward_step
127    o new verification experiment, cpl_aim+ocn:
128       coupled ocean - AIM atmosphere on cs32 grid.
129    
130    checkpoint52d_pre
131    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
132    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
133    
134    checkpoint52c_post
135    o Fixing OPTIONS files for use of exf:
136      - ALLOW_ECCO not needed
137      - ECCO_CPPOPTIONS.h should not be included from
138        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
139        as has been the case in the past
140      - All cal/exf related options are currently set in
141        single header file. Should remain so until we
142        agree on a consistent new policy.
143    o Removed all CPP options for cal package.
144      cal has no more CPP options.
145    o modified STOREs in GAD_ADVECTION
146    o corrected key comp. for passkey
147    
148    checkpoint52b_post
149    o new version: "thsice" of thermodynamic sea-ice pkg:
150     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
151     - modify fluxes but do not change theta directly;
152     - light cleaning of bulk_force pkg (still needed with thsice).
153     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
154       + output_thsice.txt to test thsice & bulk_force pkgs.
155    o put back grid & coriolis monitor output.
156    checkpoint52b_pre
157    
158    o call "do_the_model_io" at the beginning (=> dump initial state)
159    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
160    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
161      (need info on NUMBER_OF_PTRACERS)
162    o missing PTRACERS headers in some routines
163    o default tamc.h in pkg/autodiff supposed to crash
164      to ensure proper customization
165    
166    checkpoint52a_post
167    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
168      - moved surfaceTendencyTice from pkg/seaice to main code
169      - subroutine FREEZE_SURFACE now limits only surface temperature
170        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
171        => new output.txt for global_ocean.cs32x15 & global_with_exf
172      - keep the old version of FREEZE for backward compatibility;
173        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
174      - corresponding modifs for TAF directives
175    o added surface flux output variables to TIMEAVE_STATVARS
176    o time-averaged output for pkg/ptracers

182    o some bug fixes for #undef REAL4_IS_SLOW
183    
184    checkpoint52 = ecco_c52_e35
185    o after testing adjoints of checkpoint51u_post
186    
187    checkpoint51u_post
188    o this is the post-merge tag of the ecco-branch
189      (needs another clean checkout and re-testing)
190    o various natl_box_adjoint configs and results
191      but no input fields
192    o obcs adjoint not yet merged!
193    o adding ECCO global 1x1 and 2x2 degree configs
194    o updated/extended some store directives for seaice
195    o pkg/ecco now containes ecco-specific part of cost function
196    o top level routines the_main_loop, forward_step
197      supersede those in model/src/
198      previous input data.cost now in data.ecco
199      (new namelist ecco_cost_nml)
200    o in ctrl/ cleaned some cross-dependencies and updated CPP options
201    
202    checkpoint51t_post
203    o this is the pre-merge tag of the ecco-branch
204    
205    checkpoint51s_post
206    o cleanup: removed various obsolete #define-s
207    o pkg/grdchk
208      - renamed 'ph-grd 3' to 'grad-res'
209      - merged from ecco-branch
210        (remaining bug fixes for obcs gradient checks)
211      - additional high-precision output for testreport
212        (grep for 'precision_grdchk_result')
213    
214    checkpoint51r_post
215    o cleaned up or removed CPP_OPTIONS.h files
216    o updated results for some of the tests to reflect the new
217      optfiles (-ieee: -O0 instead of -O3)
218    
219    checkpoint51q_post
220    o cd_code:
221      - moved cd_scheme.F -> cd_code_scheme.F
222      - separate read_checkpoint from cd_code_ini_vars.F
223      - separated cd_code part from write_checkpoint
224      - updated AD_SOURCE, generated .flow
225      - added CD_CODE_VARS.h to the_main_loop
226      - Moving cd_code specific store dir.s to pkg/cd_code
227    o ctrl package totally restructured
228      - pack/unpack now optional and decoupled from
229        xx_/adxx_ I/O
230      - ctrl_pack/unpack cleaned
231        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
232      - confined inclusion of AD_CONFIG.h to where necessary.
233    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
234    
235    checkpoint51p_post
236    o create initial cd_code package
237      - WARNING: the initialization of fields within packages
238        is broken because INI_FIELDS (where READ_CHECKPOINT is
239        called) is called *before* PACKAGES_INIT_VARIABLES.
240        This seems to be backwards since
241        1) its important to initially zero the entire field including
242           the "halo" region
243        2) zeroing needs to be done *before* reading pickup info
244           and the pickup call might or might not happen in any
245           particular run
246      - this needs an overhaul for R2
247    o cleanup verification/*/code/GMREDI_OPTIONS.h
248    o cleanup testreport
249

258    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
259    o bug fix in find_alpha.F for MDJWF:
260      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
261        change rho -> rho-rhoConst
262      - replace call find_rho to find_rhonum
263    o initialisation of rFlx extended to full array (required by TAF)
264      and shifted to thermodynamics
265    o removed PTRACERS.h in ptracers routine
266    o added surfacetendencyPtr to S/R parameter list pracers_forcing

285         global_ocean.cs32x15, and global_with_exf)
286    o added surface flux output variables to TIMEAVE_STATVARS
287    
288    checkpoint51n_pre
289    o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F

314    
315    checkpoint51k_post
316    o change default to: useNHMTerms=.FALSE.

342    
343    checkpoint51i_post
344    o merge of the branch-genmake2

416      (relevant for cluster I/O to local disk)
417    `
418    >>>checkpoint51b_post
419    adjoint of ptracers
420    o disentangled ALLOW_PTRACERS using new ALLOW_GCHEM
421    o extended state in checkpoint_lev?, etc.
422    o alternative ctrl/cost with tr1 or ptracer
423    o new comlev1_bibj_ptracers
424    o new ptracers.flow
425    o made ptracers_forcing same as external_forcing_s
426    o added verification for adjoint with ptracers
427      - adm. grdchk fail so far
428      - tlm. grdchk OK
429      - checked tapelev/comlev recomputations: OK
430    <<<checkpoint51b_pre
431    
432    checkpoint51a_post
433    o added code for biogeochemistry package
434      - new pkgs: dic, gchem
435      - new subroutine in ptracers
436    o modify code for biogeo packages
437      - in model/src and pkg/ptracers
438    
439    checkpoint51
440    o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN
441      - autodiff, ctrl, exf, grdchk, seaice
442      kept separate packages
443      - cost, ecco, obcs
444    o updating verification/internal_wave, verification/lab_sea
445      (all verif's pass on faulks.lcs.mit.edu RH7.3, g77)
446    
447    checkpoint50i_post
448    o Preparing next differentiable checkpoint and sync
449      of MAIN vs. ecco-branch
450      - 1st step: this one is differentiable
451      - 2nd step: next(! not this) checkpoint will have updated packages
452                  from ecco-branch)
453    
454    checkpoint50h_post
455    o new package "land": provide surface BC for AIM.
456    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
457    o AIM: use true log-P extrapolation for near surface temp (= as in
458        F.Molteni paper) ; update aim.5l_cs output.
459    o New variable in PARM03 for more flexible pickups
460    o somewhat cleaned package initialisation sequence for
461      ctrl/ cost/ ecco/ in packages_... routines
462    
463    checkpoint50g_post
464    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
465      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
466      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
467        made the default because of faster convergence than ADI
468    
469    checkpoint50f_post
470    o exf totally restructured
471      - replaced all exf_set_ routines by one generic exf_set_gen.F
472        and made sure it's still differentiable
473      - split exf_getffields.F into new exf_bulkformulae.F
474      - exf_inscal_/exf_outscal_ suffixes consistent with field names
475      - updated adjoint/makefile and relevant verif. accordingly
476    
477    checkpoint50f_pre

479          + change Evap over land. (update aim.5l_cs output)
480     o added missing .cvsignores and made uniform across expts
481     o changed configuration of tidal_basin_2d expt
482     o added pkg/debug functions for tracing code in fatal crashes
483     o tidied pkg/monitor to use MONITOR_OPTIONS.h
484     o new fn in pkg/monitor to stop model if solution grows too big
485     o removed lots of single quotes from comments
486    
487    checkpoint50e_post
488    o make KPP work with PTRACERS
489     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
490       nearly a copy of kpp_transport_s
491     - there is no analogue to SurfaceTendencyS, so I have to use
492       gPtr(of the surface layer) instead
493    o add a new platform SunFire+mpi (SunFire 15000) to genmake
494    checkpoint50e_pre
495    
496    checkpoint50d_post
497    o change kpp output from multiple-record state files to single-record state
498      files analogous to write_state.F
499    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
500      analogous to the cg2d-related output.
501    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
502      so that writing to internal file fn (with length 512) fails.
503    checkpoint50d_pre
504    
505    checkpoint50c_post
506    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
507    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
508    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
509    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
510    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
511    
512    checkpoint50c_pre
513    Merging from release1_p13:
514    o bug fix for pkg/seaice dynamic solver
515    o Added SEAICE_initialHEFF to pkg/seaice
516    
517    checkpoint50b_post
518    o store u*,v* in gU,V instead of in guNm1,gvNm1
519    o in order to put the momForcing out of the Adams-Bashforth:
520      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
521      to timestep.F
522    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
523    o re-generate output for highly sensitive test-exp:
524       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
525    
526    checkpoint50b_pre
527    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
528    o corrected CPP option mismatch in exf_Bulk... functions for case
529      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
530    
531    checkpoint50a_post
532    o Bug fix for merging between c50 and KPP.
533      ikey was passed from thermodynamics to kpp_calc via
534      common block rather than being recomputed in kpp_calc,
535      in contradiction with new key itdkey.
536      New key ikppkey created, and tamc.h headers updated.
537    
538    checkpoint50
539    - 2nd step of merge with ecco-branch:
540      merge changes in ecco-branch back into main trunk
541    - bug fix in find_alpha
542    - more storing in gmredi_calc_tensor.F, kpp_routines.F
543    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
544    - merged some sliced AD support routines
545    
546    checkpoint49
547    merged from ecco-branch:
548    o exf:
549      - Enable initialisation of forcing fields to constant
550        (runtime) values.
551      - in exf_getffields.F
552        Reduce i-/j-loop to interior domain, discarding overlaps.
553        That also fixes wrong TAF-key computations for key_1, key_2
554        with bulf formulae.
555      - exf_init.F modify #ifdef for exf_init_evap
556      - exf_getffieldrec.F, ctrl_getrec.F
557        The following INT-usages are not safe:
558          fldsecs  = int(fldsecs/fldperiod)*fldperiod
559          fldcount = int(fldsecs/fldperiod) + 1
560        and were modified.
561    o autodiff: checkpoint_lev...
562      - updated storing for bulk formulae (some arrays were missing)
563      - added state for seaice package
564      - synchronized with main branch
565    o DIVA:
566      Modif.s in
567      - the_main_loop.F
568      - the_model_main.F
569      and added cost_final_restore.F cost_final_store.F
570      o With these changes, it is possible to fully separate
571        the first forward run to compute the cost function (mdthe_main_loop)
572        and adjoint runs over individual DIVA intervals (adthe_main_loop)
573        into separate model executions.
574        This enables better tuning of DIVA to given queue sizes.
575      o Loss of cost function value in consecutive DIVA runs is
576        fixed by storing to 'costfinal' file.
577      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
578        beginning/end of adjoint integration is accounted for.
579      The current changes apply to TAF-1.4.26.
580      TAF has one remaining bug, requiring one manual change
581      (see MITgcm manual).
582    o cal: synchronized between MAIN and ecco-branch
583    
584    checkpoint48i_post
585    o Changes to restore differentiability of code w.r.t. previous tag
586      (mostly adding new routines to make list and replacing
587      pressure by totPhiHyd).
588    o Updated and merged grdchk package
589      - has both ADM and TLM checks
590      - works for single- and multi-proc.
591      - output cleaned
592      - worked successfully for parallel DIVA
593    o genmake:
594      - Adding -platform=SP4
595      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
596    o Modif. for DIVA:
597      ctrl_unpack should not be called in intermediate DIVA interval.
598      (similar thing would apply for active files such as
599      tbar, sbar, psbar, which should not be reinitialised;
600      only relevant for ecco-branch)
601    
602    checkpoint48h_post
603    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
604    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
605    o Added SEAICE_initialHEFF to pkg/seaice
606    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
607    
608    checkpoint48g_post
609    --- EOS:
610    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
611      store total Potential in totPhyHyd for diagnostics & EOS.
612    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
613    --- Pressure/geopotential gradient:
614    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
615    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
616      ( changes results of global_ocean_pressure )
617    o NLFS + z-coord.: add eta*Rho' contribution.
618    o accurate phiHyd when using interface-W at the middle between 2 centers
619     ( changes results of ideal_2D_oce )
620    o includes r* 2nd term in potential gradient.
621    
622    checkpoint48f_post
623    Merging from release1_p12:
624    o Modifications for using pkg/exf with pkg/seaice
625      - improved description of the various forcing configurations
626      - added basic radiation bulk formulae to pkg/exf
627      - units/sign fix for evap computation in exf_getffields.F
628      - updated verification/global_with_exf/results/output.txt
629    o Added pkg/sbo for computing IERS Special Bureau for the Oceans
630      (SBO) core products, including oceanic mass, center-of-mass,
631      angular, and bottom pressure (see pkg/sbo/README.sbo).
632    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
633      to avoid negative values in shallow regions.
634      - updated verification/natl_box/results/output.txt
635      - updated verification/lab_sea/results/output.txt
636    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
637    o Added useSingleCpuIO option (see PARAMS.h).
638    o Updated useSingleCpuIO option in mdsio_writefield.F to
639      work with multi-field files, e.g., for single-file pickup.
640    o pkg/seaice:
641      - bug fix in growth.F: QNET for no shortwave case
642      - added HeffFile for specifying initial sea-ice thickness
643      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
644    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
645      kpp_transport_t.F, forward_step.F, and the_main_loop.F
646    o pkg/seaice:
647      - adjoint-friendly modifications
648      - added a SEAICE_WRITE_PICKUP at end of the_model_main.F
649    
650    checkpoint48e_post
651    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
652    o dynamics: change definition of computational domain & adapt mom_fluxform
653      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
654    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
655        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
656        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
657        global_ocean.90x40x15 global_with_exf global_ocean_pressure
658        inverted_barometer solid-body.cs-32x32x1
659      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
660    
661    checkpoint48d_post
662    o in preparation for r*:
663     a) use pre-computed gradient of hydrostatic potential:
664        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
665     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
666        => affects results of glob_oce_pressure (different truncation error)  
667      update output.txt of ideal_2D_oce & global_ocean_pressure
668    
669    checkpoint48d_pre
670    o in preparation for r*:
671      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
672      pass the 2 comp. of the grad. as arguments to momentum S/R.
673      but for the moment, only used if it does not change the results.
674    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
675    
676    checkpoint48c_post
677    Modifications in treatment of initial flux forcing controls
678    to avoid extra storing of flux fields.
679    
680    checkpoint48c_pre
681    o Added tidal_basin_2d experiment (currently 1D!)
682    o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented)
683    
684    checkpoint48b_post
685    o r* coordinate added in #ifdef NONLIN_FRSURF block.
686     (modification to pressure gradient not yet implemented)
687    o mom_fluxform: new S/R mom_calc_rtrans.F computes vertical transports
688      (for U & V) that are used for vertical advection of momentum.
689    
690    checkpoint48a_post
691    o In preparation for r*, use temp. array to compute vertical transport
692       in flux-form momentum pkg. => change results of few test-exp.
693      Update output of: exp4, exp5, front_relax, global_ocean_pressure,
694                        lab_sea, natl_box & plume_on_slope
695    
696    checkpoint48
697    o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D')
698    
699    checkpoint47j_post
700    o add new exp. (ideal_2D_oce) to test "exotic" parameters and options.
701    o moved adexch from forward_step to addummy_in_stepping
702    o added exch in ctrl_map_...
703    o aveFreq.=0. at end of cost_final to avoid overwrite in
704      reverse checkpointing loop
705    o Yet more changes in gmredi:
706      * adgmredi_calc_tensor
707        avoiding all recomputation of gmredi_slope_limit
708      * adgmredi_x/y/rtransport
709        added flag for excessive storing to avoid recomp. of
710        u/v/rtans, dTdx/y/z
711        -> this is not really necessary and very memory-consuming
712      * adgmredi_slope_psi:
713        consistency with gmredi_slope_limit in treatment of GM_slopeSqCutoff
714      * gmredi_slope_limit
715        re-activated full calculation of taperfct for case 'ac02'
716    o updating verification/ adjoints of carbon, global_ocean.90x40x15
717    
718    checkpoint47i_post
719    o GM_EXCLUDE_() replace GM_TAPER_(): by default, all the code is compiled.
720    o add GM_Small_Number & GM_slopeSqCutoff as run-time parameters (data.gmredi)
721      default values = 1.D-12 & 1.D+48 (=> give same results as checkpoint47f_post)
722    o cg2dTargetResWunit: define tolerance using deltaTmom (and not deltaTfreesurf)
723    o gmredi: fix few bugs.
724    
725    checkpoint47h_post (duplicate tag for PH's c48 tag, in order to move c48)
726    This will be a good checkpoint to plug into the ecco-branch.
727    o few modif.'s to get latest version adjointed
728      (mainly kick out code in ini_linear_phisurf)
729    o modif's to run adjoint with exactConserv
730    o case GM_BOLUS_ADVEC should be cleaned
731      S/R gmredi_slope_psi should be cleaned
732    o verification/carbon now has exactConserv=.TRUE.
733    
734    checkpoint47g_post
735    o time-average AIM output: becomes independent from statvars time-average
736      (can be used with #undef ALLOW_TIMEAVE) ; add new variables (e.g., RH)
737    o After TAF bug fix:
738      Tested adjoint of gmredi package.
739      Tests were done with checkpoint47 rather than with latest
740      checkpoint47f_post since the latter is broken for the adjoint
741      verification/carbon/ contains both ADM and TLM gradient checks.
742    Here they are, before they get changed/lost/stolen.
743    Mostly modif.'s to fix numerical sensitivities.
744    Gradient checks OK for
745    - GM_taper_scheme:
746      * clipping
747      * ac02
748      * linear
749      * glw91
750      * dm95
751      * ldd97
752    - GMREDI_OPTIONS:
753      * GM_VISBECK_VARIABLE_K
754      * GM_NON_UNITY_DIAGONAL
755      * GM_EXTRA_DIAGONAL
756      * GM_BOLUS_ADVEC
757    in conjunction with data.gmredi parameters to be checked in
758    in a few minutes under verification/carbon/code/
759    
760    checkpoint47f_post
761    Merging from release1_p10:
762    o modifications for using pkg/exf with pkg/seaice
763      - pkg/seaice CPP options SEAICE_EXTERNAL_FORCING
764        and SEAICE_EXTERNAL_FLUXES
765      - pkg/exf CPP options EXF_READ_EVAP and
766        EXF_NO_BULK_COMPUTATIONS
767      - usage examples are Experiments 8 and 9 in
768        verification/lab_sea/README
769      - verification/lab_sea default experiment now uses
770        pkg/gmredi, pkg/kpp, pkg/seaice, and pkg/exf
771    
772    checkpoint47e_post
773    o created a tag prior to creating a branch
774    
775    checkpoint47d_post
776    o fixed bug in the oceanic pressure coordinates code: vertical viscosity
777      at the bottom boundary had an erroneous half slip boundary condition
778    o added bottom drag and no slip boundary condition capabilities to
779      oceanic pressure coordinates code
780    o added new verification experiment global_ocean_pressure, this experiment is
781      also described in the tutorial section of the manual
782    checkpoint47d_pre
783    
784    checkpoint47c_post
785    o Added a verification experiment for a global cubed-sphere ocean run
786      -  verification/global_ocean.cubed32x32x30
787      -  uses pkg/therm_seaice and pkg/bulk_forcing
788    
789    o allow to run AIM physics with SPEEDY input files (from Franco Molteni)
790    o allow a more accurate definition of Ro_Surf (selectFindRoSurf=1)
791      when using P-coordinate; only implemented for atmospheric config.
792    o OCEANICP & realFreshWater: include P-E direct effect on wVel ;
793      NOTES: requires option NONLIN_FRSURF to be "#define".
794    o update advect_xz/results/output.txt (left from checkpoint44g_post)
795    
796    checkpoint47b_post
797    Merging from release1_p9:
798    o pkg/seaice
799      - removed GOTO's and added taf directives
800      - double precision constants to reduce the g77 (Linux)
801        to F77 (SGI) differences reported in release1_p8
802    o tools/genmake
803      - added SGI options
804    o verification/testscript

811      - added test of thermodynamics parallelization
812    
813    checkpoint47a_post
814    o new pkg: aim_v23
815     = F. Molteni atmos.physics (SPEEDY, ver23) adapted to MITgcm.
816       for now, keep the same surface forcing as before.
817     - Part-Cell implemented into AIM; check that Heat & Water are conserved
818     - aim.5l_cs: use new aim pkg (run 10yr & get better results than before)
819     - aim.5l_LatLon & aim.5l_Equatorial_Channel are still using old aim pkg
820    o add diagnostic of surface correction term in monitor output
821    
822    o bulk_force and therm_seaice
823    - Two packages:  bulk_force (Bulk forcing)
824      and therm_seaice (thermodynamic_seaice) - adopted from LANL CICE.v2.0.2
825    - Earlier integration from Stephaine Dutkiewicz

832    o bug fix in quasihydrostaticterms
833    o * "clean" adjoint code (in terms of extensive recomputations)
834        can now be obtained for all GMREDI options (i.e. for
835        - GM_VISBECK_VARIABLE_K
836        - GM_NON_UNITY_DIAGONAL
837        - GM_EXTRA_DIAGONAL
838        - GM_BOLUS_ADVEC )
839      * However, wrong gradient check problem remains unsolved.
840      * New CPP options have been introduced for different
841        tapering schemes
842    o external_fields_load now part of differentiation list
843    o pressure needs multiple storing;
844      would be nice to have store_pressure at beginning or
845      end of forward_step, e.g. by having phiHyd global (5-dim.)
846      (NB: pressure is needed for certain cases in find_rho,
847      which is also invoked through convective_adjustment).
848    o recomputations in find_rho for cases
849     'JMD95'/'UNESCO' or 'MDJWF' are OK.
850    o #define ATMOSPHERIC_LOADING should be differentiable
851    o ini_forcing shifted to begining of initialise_varia
852    o Incorporating QNVS line search routines into MITgcm
853      (this is separate code, and therefore not under pkg)
854      lsopt/, optim/
855    o Updated verification/carbon/
856      - #define GM_VISBECK_VARIABLE_K
857      - GM_taper_scheme    = 'ldd97'    
858    
859    checkpoint46n_post
860    Merging from release1_p8:
861    o verification/natl_box:
862      updating new external_fields_load routine
863    o New package: pkg/seaice
864      Sea ice model by D. Menemenlis (JPL) and Jinlun Zhang (Seattle).
865      The sea-ice code is based on Hibler (1979-1980).
866      Two sea-ice dynamic solvers, ADI and LSR, are included.
867      In addition to computing prognostic sea-ice variables and diagnosing
868      the forcing/external data fields that drive the ocean model,
869      SEAICE_MODEL also sets theta to the freezing point under sea-ice.
870      The implied surface heat flux is then stored in variable
871      surfaceTendencyTice, which is needed by KPP package (kpp_calc.F and
872      kpp_transport_t.F) to diagnose surface buoyancy fluxes and for the
873      non-local transport term.  Because this call precedes model
874      thermodynamics, temperature under sea-ice may not be "exactly" at
875      the freezing point by the time theta is dumped or time-averaged.
876      N.B.: fairly large differences in accuracy occur across
877            different platforms/compilers; comparison between
878            g77 (Linux) and F77 (SGI Origin 2000/MIPSpro)
879            generated output gives:

885    
886      Y Y Y Y  5  5  7  7  7  8 10  9  6  6  6  6  7  5  7  5  7 FAIL  lab_sea
887    o GAD:
888      - generated new common blocks to account for call of
889        same gad routines with differing traceridentities
890        (needed to modify tracerIdentity indices in GAD.h)
891      - generated separate common blocks for case useCubedSphereExchange
892        (Department of Futurology)
893      - parameter lists to gmredi_?transport: added tracerIdentity
894      - added new key indices to tamc.h
895    o external_fields_load:
896      - added this routine to TAF list
897      - needed to make some common blocks global and additional storing
898        along the same lines as exf package (checkpoint_lev?_directives.h)
899    o exf:
900      updated external forcing package
901      - bug fixes carried over from ecco-branch
902        (missing OBCS_OPTIONS.h in two routines)
903      - enable easy to use "no forcing".
904      - added exf I/O for atmospheric loading
905      - added exf I/O for runoff data
906      - transfered scaling between exf <-> MITgcm to exf namelist
907    o Adding new verification experiment global_with_exf.
908      This verification experiment is almost identical to the
909      global_ocean.90x40x15 experiment, except that it uses
910      the exf (and cal) package instead of the
911      external_fields_load routine (cf README file).
912    
913    checkpoint46m_post
914    o modified testscript to return -- when there are no lines of "%MON" output
915    o added new flag "quasiHydrostatic" for QH mode
916      and new routine quasihydrostaticterms()
917    o added 2*Omega*Cos(phi)*W to u equations (non-hydrostatic Coriolis term)
918      New routine: mom_u_coriolis_nh()
919    o fixed sign of non-hydrostatic metric terms in u and v equations.
920      Depend on correct sign of gravitySign.
921    o added work.pc* to .cvsignore in aim directories using ifc
922    o introduced flag for controllin non-hydrostatic metric terms
923    o removed gravitySign from PARM04
924    o switched to g77/ifc from pgf77 in aim experiments
925    
926    checkpoint46l_post
927    o made convective adjustment work with pressure coordinates:
928     - changed the direction of k-loop in convective_adjustment.F for the
929       case of pressure coordinates (OCEANICP,ATMOSPHERIC buoyancyRelation)
930     - adjusted the reference pressure k-index in convective_adjustment.F
931     - adjusted the convection condition in convect.F (in analogy to
932       calc_ivdc.F)
933     - convective_adjustment no longer computes anything on the halos
934     - removed the warnings about negative salinity from find_rho.F and
935       find_alpha.F; instead the new routine look_for_neg_salinity, called
936       at the beginning of find_rho, find_alpha, and find_beta, does a
937       check of the entire slice, if CPP-option
938       CHECK_SALINITY_FOR_NEGATIVE_VALUES is defined
939    checkpoint46l_pre
940    
941    checkpoint46k_post
942    o fixed the verification/global_ocean.90x40x15 experiment:
943     - new bathymetry (the world according to A., JMC, and M.)
944     - new initial fields and forcing fields (*.bin files)
945     - new POLY3.COEFFS (for the next release one should switch to a full
946       equation of state: JMD95P or MDJWF)
947     - fixed several errors and redundancies in the data file
948     - experiment uses looped cells
949     - added matlab directory with diagnostic scripts for plotting of output
950    
951    o S/R aim_initialise.F replace S/R aim_init from file aim_do_inphys.F:
952     - read AIM physics parameters from a file (data.aimphys)
953     - set defaults values = F.Molteni paper (Clim.Dyn., 2002)
954    
955    checkpoint46j_post
956    o split calc_exact_eta in 2 S/R : integr_continuity & update_etaH
957    o move wVel computation at the end of the time step, in S/R integr_continuity
958    o create specific S/R to exchange T,S before DYNAMICS (for stagger time step)
959    o update timeave pkg for wVel diagnostic.
960    checkpoint46j_pre
961    
962    checkpoint46i_post
963    o Clean up AIM package (and keep the results unchanged):
964      include CPP_OPTION and use IMPLICT NONE in all routines ;
965      declare all the variables _RL ; use _d 0 for all numerical constants.
966      use ifdef ALLOW_AIM everywhere. And now AIM can be used with g77 !
967    
968    checkpoint46h_post
969    o cleaned up the use of rhoNil and rhoConst.
970      - rhoNil should only appear in the LINEAR equation of state, everywhere
971        else rhoNil is replaced by rhoConst, e.g. find_rho computes rho-rhoConst
972        and the dynamical equations are all divided by rhoConst
973    o introduced new parameter rhoConstFresh, a reference density of fresh
974      water, to remove the fresh water flux's dependence on rhoNil. The default
975      value is 999.8 kg/m^3
976    o cleanup up external_forcing.F and external_forcing_surf.F
977      - can now be used by both OCEANIC and OCEANICP
978    checkpoint46h_pre
979    
980     Added code to convert surface volume flux (fresh water) into
981     a mass flux when using P coordinates in the ocean (OCEANICP).
982     Note: It assumes you have set rho0=rhoConst=density of fresh water.
983    
984    checkpoint46g_post
985    o Include a new diagnostic variable phiHydLow for the ocean model
986      - in z-coordinates, it is the bottom pressure anomaly
987      - in p-coordinates, it is the sea surface elevation
988      - in both cases, these variable have global drift, reflecting the mass
989        drift in z-coordinates and the volume drift in p-coordinates
990      - included time averaging for phiHydLow, be aware of the drift!
991    o depth-dependent computation of Bo_surf for pressure coordinates
992      in the ocean (buoyancyRelation='OCEANICP')
993      - requires a new routine (FIND_RHO_SCALAR) to compute density with only
994        Theta, Salinity, and Pressure in the parameter list. This routine is
995        presently contained in find_rho.F. This routine does not give the
996        correct density for 'POLY3', which would be a z-dependent reference
997        density.
998    o cleaned up find_rho
999      - removed obsolete 'eqn' from the parameter list.
1000    o added two new verification experiments: gop and goz
1001      (4x4 degree global ocean, 15 layers in pressure and height coordinates)
1002    checkpoint46g_pre
1003    
1004    checkpoint46f_post
1005    o Enable tangent linear (forward mode) gradient checks:
1006      - extended active file handling to g_... files
1007      - added TANGENT_SIMULATION to theSimulationMode
1008      - extended grdchk package accordingly
1009    o added tangent linear setup in verification/carbon/code_ftl
1010    o added adjoint setup in verification/front_relax/code_ad
1011    
1012    checkpoint46e_post
1013    o Added new equation of state -> MDJWF
1014      - EOS of McDougall et al., 2002, JAOT, submitted
1015      - caveat: the equation of state is only valid for a smaller (more
1016        realistic?) range of values than JMD95P/Z and UNESCO
1017      - added masks to the calculation of pressure in store_pressure
1018      - added more check values for density in check_eos (ini_eos.F), some of
1019        the old check values are out of the range of the MDJWF-eos, so don't
1020        expect perfect matches for those
1021    checkpoint46e_pre
1022    
1023    checkpoint46d_post
1024    o fixed store_pressure to work with both buoyancy relation = 'OCEANIC' and
1025      'OCEANICP', also initialised field pressure correctly in ini_eos in the
1026      case of pressure coordinates. eosType='JMD95Z' in
1027      combination with buoyancyRelation='OCEANICP' now causes an error.
1028    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
1029      in find_alpha/beta.
1030    checkpoint46d_pre
1031    
1032    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
1033      so that JMD95Z and JMD95P give approptiate static stability in find_rho.
1034    
1035    checkpoint46c_post
1036    o Changes necessary for ocean in p-coordinates
1037     -  Added new buoyancy relation = 'OCEANICP'
1038     -  Added new parameters = gravitySign (this used to be contained inside
1039        the factor dRdZ which I added when we first switched to R coordinates).
1040     X GM/Redi is not compatible (yet)
1041     X bottom drag and no-slip need to be debugged.
1042    checkpoint46c_pre
1043    
1044    checkpoint46b_post
1045    o Added new equation of state -> JMD95Z and JMD95P
1046      - EOS of Jackett and McDougall, 1995, JAOT
1047      - moved all EOS parameters into EOS.h
1048      - new routines ini_eos.F, store_pressure.F
1049    o Added UNESCO EOS, but not recommended because it requires
1050      in-situ temperature (see JMD95)
1051    o Modified formatting for knudsen2.f in utils/knudsen2 and added
1052      unesco.f to be used with POLY3
1053    checkpoint46b_pre
1054    
1055    checkpoint46a_post
1056    o Added (atmospheric) pressure loading
1057      - new field in FFIELDS.h, etc...
1058      - new cpp flag ATMOSPHERIC_LOADING
1059    o Changed hFacC to _hFacC in calc_phi_hyd.F
1060    o Added SHORTWAVE_HEATING to some files for consistency
1061    checkpoint46a_pre
1062    
1063    checkpoint46
1064    further merges from release1_p5
1065    o new ctrl package
1066      - adopted from ECCO environment to enable optimization
1067      - added Eliassen Palm fluxes to controls
1068    o added Eliassen Palm flux controls to gradient check package
1069    o cost package
1070      - Compatible with new ctrl package
1071      - added Eliassen Palm cost hooks
1072      - modif's of existing cost functions
1073    o Adjoint-related bug fixes in kpp:
1074      - kpp_calc: sore of kpphbl avoids recomputation/call to S/R kppmix
1075      - kpp_routines: store of Rib avoids partial recomputation bug of TAF.
1076    o autodiff package
1077      - flow directives:
1078        + new for S/R do_the_model_io
1079        + enhanced for S/R checkpoint
1080        + new gmredi.flow
1081      - Introduced CPP option ALLOW_AUTODIFF_MONITOR to
1082        disable adcommon.h/g_common.h by default.
1083      - fixed problem for adjoint of global_max
1084    o modified verification/carbon/
1085    o New setup for adjoint of global_ocean
1086    o added hooks for Eliassen Palm fluxes (dynamics.F, ini_fields.F)
1087    o cleaned TAF keys iikey, idkey (dynamics.F, thermodynamics.F)
1088    o incorporated hooks for sponge layer code (external_forcing.F)
1089    
1090    checkpoint45d_post
1091    o import 2 fixes from release1_p5 (CG2D.h & packages_readparms.F)
1092    o use recip_dx*,recip_dy* instead of /dx*,/dy* in orlanski_E,W,N,S
1093      (affects plume_on_slope "cg2d" output)
1094    o add new parameter deltaTfreesurf for free-surface time stepping
1095    o exchange gT,gS when using staggerTimeStep & GM & Oly<4
1096    o NONLIN_FRSURF: rescale gNm1 to get a better conservation with A-B
1097    o change phiMin in exp1 (to agree with documentation)
1098    o add new flags:
1099     - T,S forcing inside/outside Adams-Bashforth
1100     - turn off temp,salt advection and/or forcing
1101     - for each tracer, define internal flag for multiDimAdvection & A-B
1102    o monitor: change definition of KE to check conservation of Energy
1103    
1104    checkpoint45c_post
1105    o Removed f90 comments ("!")
1106    o Modified initialisations to enable exf package for MITgcm
1107      (without invoking ECCO_PACKAGE).
1108    o modifications to gradient check package (Martin Losch)
1109      - enable centered differences
1110      - modified format of standard output
1111    
1112    checkpoint45b_post
1113    o cleaned exchange calls in cg2d
1114    o Included CPP option ALLOW_AUTODIFF_MONITOR in forward_step
1115    o included CPP option SINGLE_LAYER_MODE in thermodynamics
1116      to configure barotropic setup (Martin Losch)
1117    o moved some initialisations within bi,bj loop in dynamics
1118      (TAF flow dependency)
1119    o in initialise_varia, moved call packages_init_variables
1120      before convective_adjustment_init
1121      (corresponding adjustment of TAF tape initialisation).
1122    o in calc_diffusivity/calc_viscosity extended domain to full overlap.
1123    
1124    checkpoint45a_post
1125    o compute Rho over the whole domain (extend iMin,jMin indices)
1126    o specific exchange for X-slice domain (case Ny=1)
1127    o argument futureIter of S/R obcs_calc missing in exp4 & internal_wave /code
1128    o solve_for_pressure : set cg2d_x to zero where OBCS are applied
1129    
1130    checkpoint44h_post = checkpoint45
1131    o Fix to restore differentiability:
1132      place at which packages_init_variables is called in
1133      initialise_varia is crucial for reverse control flow.
1134    o modifications in GMRedi to enable stable adjoint
1135      (corresponding modif's in thermodynamics, dynamics)
1136    o added missing hook for sponge layer code in external_forcing
1137    o modified test cost functions
1138    o storing in gad_advection (plus removal of write(0,*)!
1139    o missing headers TR1.h added in convective_adjustment routines
1140    o errorMessageUnit set non-equal zero in eeboot
1141      (conflict on some platforms, e.g. IBM SP3)
1142    o modified carbon verif.
1143    
1144    checkpoint44h_pre
1145    o vertical grid option: allow to put the Interface at the middle between
1146      2 cell-centers ; replace delZ in pkg/kpp by drF.
1147    o GM Advective form: Tracers are advected using the residual transport (=
1148      Euler+GM-bolus); set param GM_AdvSeparate=T to return to previous form.
1149    
1150    checkpoint44g_post
1151    o fix surface correction term in multiDimAdvection (affects plume_on_slope
1152      results) ; ifdef missing in thermodynamics.F
1153    
1154    checkpoint44f_pre,checkpoint44f_post
1155    o added PTRACERS package
1156      This allows an arbitrary number of passive tracers to be integrated
1157      forward simultaneously with the dynamicaly model.
1158      + Implemented so far:
1159        - basic forward algorithm (time-stepping, advection, diffusion, convection)
1160        - I/O and checkpointing
1161        - GM/Redi  *but*  using the GM/Redi coefficient of Salt
1162      + Not implemented so far:
1163        - KPP
1164        - OBCS
1165      + No specific example supplied (yet) but global_ocean.90x40x15 has the
1166        necessary data.ptracer file. Simply use -enable=ptracers and uncomment
1167        line in data.pkg.
1168      + This package is disabled by default since it increases storage.
1169    
1170    
1171    o testscript: added -cleanup option
1172    o Shap_filt: a) new shap_filt S/R to use no-slip BC with S2 filter
1173                 b) enable to filter 2D fields.
1174    
1175    checkpoint44e_pre,post
1176    o re-wrote convective adjustment to use pre-calculated weights
1177      Affects: model/src/convective_adjustment.F, convective_adjustment_ini.F
1178      Adds:    model/src/convective_weights.F, convectively_mixtracer.F
1179      Original calls to convect() still in place.
1180    
1181    chkpt44d_pre,post
1182    o added missing EXCLUDE_MONITOR flags
1183    o changed "e" to "_d" in gmredi_slope_limit, gmredi_slope_psi
1184      (incompatible typ in MIN/MAX expressions caused problems
1185      on IBM SP3)
1186    o in genmake added variable MAKEDEPEND
1187      plus resetting for case SunOS
1188    o added timer_stats.c routine for IBM SP3
1189    o removed variables in dynamics
1190    !!! I forgot to create tag chkpt44d_pre !!!
1191    !!! But chkpt44d_pre = chkpt44c_post    !!!
1192    
1193  o real fresh water flux implemented with non-linear free-surface.  o real fresh water flux implemented with non-linear free-surface.
