5    
6    checkpoint45c_post
7    o Removed f90 comments ("!")
8    o Modified initialisations to enable exf package for MITgcm
9      (without invoking ECCO_PACKAGE).
10    o modifications to gradient check package (Martin Losch)
11      - enable centered differences
12      - modified format of standard output
13    
14    checkpoint45b_post
15    o cleaned exchange calls in cg2d
16    o Included CPP option ALLOW_AUTODIFF_MONITOR in forward_step

24    o in calc_diffusivity/calc_viscosity extended domain to full overlap.
25    
26    checkpoint45a_post
27    o compute Rho over the whole domain (extend iMin,jMin indices)

29    o argument futureIter of S/R obcs_calc missing in exp4 & internal_wave /code
30    o solve_for_pressure : set cg2d_x to zero where OBCS are applied
31    
32    checkpoint44h_post = checkpoint45
33    o Fix to restore differentiability:
34      place at which packages_init_variables is called in
35      initialise_varia is crucial for reverse control flow.
36    o modifications in GMRedi to enable stable adjoint
37      (corresponding modif's in thermodynamics, dynamics)

45    
46    checkpoint44h_pre
47    o vertical grid option: allow to put the Interface at the middle between
48      2 cell-centers ; replace delZ in pkg/kpp by drF.
49    o GM Advective form: Tracers are advected using the residual transport (=

52    checkpoint44g_post
53    o fix surface correction term in multiDimAdvection (affects plume_on_slope
54      results) ; ifdef missing in thermodynamics.F
55    
56    checkpoint44f_pre,checkpoint44f_post
57    o added PTRACERS package
58      This allows an arbitrary number of passive tracers to be integrated
59      forward simultaneously with the dynamicaly model.
60      + Implemented so far:
61        - basic forward algorithm (time-stepping, advection, diffusion, convection)
62        - I/O and checkpointing
63        - GM/Redi  *but*  using the GM/Redi coefficient of Salt
64      + Not implemented so far:
65        - KPP
66        - OBCS
67      + No specific example supplied (yet) but global_ocean.90x40x15 has the
68        necessary data.ptracer file. Simply use -enable=ptracers and uncomment
69        line in data.pkg.
70      + This package is disabled by default since it increases storage.
71    
72    
73    o testscript: added -cleanup option
74    o Shap_filt: a) new shap_filt S/R to use no-slip BC with S2 filter

95    o real fresh water flux implemented with non-linear free-surface.
96    
97    chkpt44c_pre,post
98    o few fix (mask in shap_s2, EmPmR in external_field_load,
99      USE_NATURAL_BCS in solve_for_P);
100    o add arguments myIter & myTime to S/R obcs_calc & solve_for_P
101    
102    checkpoint44b_pre/_post

132      Fixed AD-related problems:
133    o Store directives up-to-date with re-arranged Adams-Bashforth
134      (mainly thermodynamics.F)
135    o New store directives for multi-dim. advection schemes
136      * new CPP flag ALLOW_MULTI_DIM_ADVECTION

144    o re-formatted/added comments in prologues of key subroutines
145      to work with protex
146    
147    checkpoint40
148    o moved calc_gs, calc_gt and calc_tr1 back to model/src

163    o added/updated many matlab scripts
164    o added multi-dimensional advection method for tracers
165      
166    checkpoint40pre8
167    o new package rw/
168      Added method for dumping intermediate local arrays:
169      mdsio_writetile - same as mdsio_writefield except works from inside
170                        bi,bj loop
171      mdsio_writelocal - same as mdsio_writetile except works for local
172                         arrays
173      write_local_r? - higher-level wrapper for mdsio_writelocal
174      Controlled by diagFreq. Defaults to zero (ie. no dumps)
175      Example given at end of mom_vecinv.F that dumps some local arrays.
176    o replaced calc_mom_rhs.F by mom_fluxform.F/mom_vecinc.F to
177      control flux-form versus vector invariant code.
178      Switch is runtime flag vectorInvariantMomentum (defaults to false)
179      or genmake -DISABLE ...
180    o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
181      (additional storing is now needed for case vecinv;
182      currently nothing implemented to switch this storing off
183      in case fluxform is used since no CPP flag available).
184    
185    checkpoint40pre7
186    o bug fix in dynamics.F
187      calc_viscosity called before k=1,Nr loop.

194    o corresponding split of calc_diffusivity into
195      calc_diffusivity, calc_viscosity
196      (kpp_calc_diff, kpp_calc_visc).
197    o Added diffkr, kapgm to control variables
198    o bug fix in gmredi_slope_limit for ldd97
199    
200    checkpoint40pre5
201    o proper initialization of Adams-Bashforth time stepping
202      + uses forward step for very first step of model (iter=0)
203    o re-generated *all* output since almost all output is modified by this
204      change (sorry but we've been putting this one off for about 2 years)
205      + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
206        *not* regenerated since they are already out of date and I don't
207        want to create the impression that they are suddenly working.
208    o removed KAP stuff for DEC's
209    o modified/added many .cvsignore files in */code and */input
210    o added new expt "solid-body.cs-32x32x1"
211      + this uses an alternative form of ini_curvilinear_grid.F which
212        is not necessarily any better than the current one...
213    
214    checkpoint40pre4
215    o added re-initialisations of utrans,vtrans,rtrans in
216      calc_common_factors which are crucial for TAF.

229    o Added gradient check package
230    o Added routines for passive tracer handling
231    o Added carbon sequestration sensitivity experiment
232    
233    checkpoint39
234     o Modifications and fixes to support TAMC
235       (mainly missing or wrong directives)
236     o Corrected common blocks when fooling TAMC to produce adjoint I/O
237       in addummy_in_stepping
238     o Updated verification/vero/ (bug fixes in code/, correct pickups in input/)
239     o Enabled "sliced" (xz-,yz-) exchanges, needed for obcs.
240     o Included following packages:
241       cal: calendar
242       exf: external forcing
243       ecco: essential routines to control use of cal, exf
244             (NB: this is not the full ECCO environment)
245     o disabled some packages by default in genmake
246    
247    checkpoint38
248     o see notes_c37_adj.txt
249     o corrected wrong layer index in external_forcing_t
250     o replaced the_main_loop/forward_step by the_main_loop
251     o removed forceoutput from write_state
252       (replaced criteria for initial/final state)
253     o added runtime flag for pre-C35 pickups: usePickupBeforeC35
254    
255    checkpoint37
256     o mdsio.F routine split and packaged in pkg/mdsio
257       (mdsio.F and mdsio_gl.F still exist in eesupp/src but are not
258        used unless genmake -disable=mdsio)
259     o allow a more precise surface-geopotential gradient for the atmosphere
260       taking into account the change in space of Alpha (=1/rho) at the surface.
261     o variable "etaN" (replace cg2d_x) is the surface R-anomaly [r unit]
262       (ocean: sea surface height [m] / atmos: surface pressure anomaly [Pa])
263     o Change units: Phi_Hydrostatic (=phiHyd), Phi_Surface(=cg2d_x) and
264       Phi_NonHydrostatic (=cg3d_x), all have now the dimension of a potential
265       [m2/s2] (pressure/rhoConst in the ocean ; Geo-Potential in the atmosphere).
266     o Time-Average diagnostics defined as a pseudo package "timeave".
267     o pickup files : old pickup (before c35) did not work with new code (c35
268       and after) unless activating 2 commented lines in initialise-varia.
269     o Non-Hydrostatic pickup file Pb fixed.
270     o bug with Rigid-lid version (since c35) fixed.  
271    
272    checkpoint36
273     o implement Crank-Nickelson barotropic time-stepping
274     o recover Time-Average diagnostics
275     o fix Pb in checkpoint (PR#19)
276     o AIM become a standard package ; clean unused CPP_kees
277    
278    checkpoint35
279     o subtantial rewrite of dynamics.f
280     o allows staggered time-stepping
281     o packaged obcs, aim (Atmospheric Physics), zonal_filt, shap_filt
282     o added bottom drag (linear + quadratic)
283    
284    checkpoint34
285     o Modified exchange routines for correct reverse simulation.
286     o Added verification output to comply with bug fix in impldiff.F
287       as of c33 (exp2, natl_box).
288     o Corrected store directives in dynamics.F
289     o Corrected array boundaries in impldiff.F
290     o Corrected array dimensions in gmredi.
291       Added temporary scalars to avoid storage by TAMC (gmredi, kpp).
292     o Added routine GLOBAL_SUM_INT to global_sum.F
293     o Added mdsio_gl.F for ECCO purposes.
294    
295    checkpoint33
296     o Fixed bug in lower BC in impldiff.F
297     o Fixed confusion about units of forcing arrays in FFIELDS.h
298       namely Fu,Fv,Qnet,Qsw,EmPmR:
299       - Removed verification/natl_box/code/external_fields_scale.F
300         (did not differ from that in model/src)
301       - Changed units of fu,fv,Qnet,Qsw,EmPmR back to proper units
302         (see FFIELDS.h for description)
303       - Scale fu,fv,Qnet,Qsw,EmPmR when used in external_forcing_surf.F,
304         kpp_calc.F and kpp_transport_t.F
305       - Removed model/src/external_fields_scale.F and calls to it
306       - verification/natl_box uses flux data with "atmospheric" sign so
307         a special version of external_fields_load.F is used to
308         change the data as it's read in. This way, the arrays
309         have the right units and signs at all times tha a user could
310         possibly use them.
311     o Corrected genmake to delete a temporary file during configuration
312    
313    checkpoint32
314     o Scaling of forcing fields moved from external_forcing.F to
315       external_fields_scale.F, called directly after loading fields.
316     o Surface relaxation terms added to surface tendency fields in
317       extra subroutine.

319       fields.
320     o Changes in GMRedi to comply with packaging structure.
321     o Modifications and bug fixes in KPP package.
322     o Verification experiment for KPP added (verification/nat_box/)

326       -> new routines packages_...F
327       -> changes in initialise_fixed.F, initialise_varia.F
328       -> enables initialisation interface for ECCO package
329     o Rescaling of external forcing fields immediately after read
330       (removed from external_forcing.F)
331       -> new: surface_fields_scale.F
332       -> affects ini_foorcing.F, external_fields_load.F
333     o Computation of surface tendencies before tendency updates.
334       -> new: external_forcing_surf.F
335     o Change of variable names useGMRedi, useKPP, useECCO
336     o Further changes in dynamics.F, impldiff.F for TAMC
337     o Tested for experiments 0, 2, 4.
338       - not yet tested for GMRedi.
339       - not yet tested for KPP.
340    
341    checkpoint30
342     o Updates for OBCs
343     o New experiment for test OBCs (internal_wave)

352    
353    checkpoint28
354     o Corrected initialization of hFacMin for difference vertical coordinates
355     o Modified calculation of partial cell thickness to more robust algorithm
356     o config_summary.F: replaced write_1D_... by write_0D_...
357       read_write.F: added subroutines write_0D_...
358     o routines calc_common_factors, calc_gs, calc_gt, calc_phi_hyd, find_rho:
359       included some initialisations required for TAMC.
360     o routine calc_isoslopes: modified sqrt computation to make it
361       differentiable for zero argument.
362     o routines dynamics, impldiff:
363       included store directives and tape key computations required for TAMC.
364     o ALL TAMC related changes are between ifdef ALLOW_AUTODIFF_TAMC
365    
366    checkpoint27
367     o fixed calc_isoslopes() to so that cancellation of terms in tensor
368       formulation works properly with variable resolution.
369     o restructured the calling tree between the_model_main() and dynamics()
370     o split initialise() into initialise_fixed() and initialise_varia()

373    
374    checkpoint26
375     o moved some #ifdef in optional routines to encompass everything
376       except the argument declarations. This was using up some memory.
377     o fixed macros like _ADT to work with both versions of Linux cpp
378     o cleaned up some unused and uninitialized variables
379       (helps when debugging with strict compile options)
380     o split up CPP_EEOPTIONS.h into options and macros
381       (macros are now in eesupp/inc/CPP_EEMACROS.h)
382     o patch for 2 processor JAM mode
383    
384    checkpoint25
385     o updates for OBCs and NH
386     o dramatically reduced memory usage
387     o added "JAM" routines for use on Artic network
388     o parameterization of convection by implicit vertical diffusion
389     o added a diagnostic of convective index
390     o moved call to calc_divg_hat() from dynamics() to solve_for_pressure()
391       (this is was partly for OBCs and NH but also in anticipation of
392        an explicit free-surface option)

448     Rewrote exchange routines to allow
449     o General tile <-> tile connectivity.
450     o TAMC reverse mode flag ( is this really needed? )
451     o Variable width overlap and exchange region widths.
452     o Hooks for sharing data via DMA, Arctic, Memory Channel,
453       shmput/shmget, VIA, SYSV shmem and every other cool
454       communication method.
455    
456    checkpoint14
457     Consistent isomorphism chages made. These allow dynamical core
458     to support both pressure and meters as a vertical coordinate.
459    
460    checkpoint13
461     Release which corrects global_max problem and a couple
462     of KGM time-averaging diagnostic errors. Also contains
463     a double-gyre experiment setup as well as the baseline
464     4 degree global template. The double gyre template is
465     organised to allow it to be applied automatically to
466     the baseline configuration.
467    
468    branch-point-rdot
469     A few tidy-ups have been made bt the real point of this
470     check-point (excuse the pun) is to allow a branch to be
471     made for the purposes of adding the rDot alterations.
472     I don't want to commit the rDot to the main-trunk until
473     we've actually tested it...
474    
475    checkpoint12
476     Tidy up and added generic genmake script (formerly
477     configure script).
478     Released to testers.
479    
480    checkpoint11
481     Re-arranged initialise() and introduced ini_vertical_grid()
482     and ini_masks_etc().
483    
484    checkpoint10
485     Introduced the configure script.
486     Separated out the diags package.
487     Added template for writing time-averages of tile/intermediate quantities.
488     Updated SIZE.h in exp2 and made the data big-endian.
489    
490    checkpoint9
491     MPI fix. Filename changes (meta/data). salbin*y stuff.
492     General tidy-up.
493     SST.bin SSS.bin added to verification/exp2
494    
495    checkpoint8
496     Inludes time-dependant forcing and time-averaging.
497     Works at 4x4 and 2.8125x2.8125 global
498    
499    checkpoint7-4degree-ref
500     Branch from checkpoint7. Released for application to
501     global modeling and general modeling - process studies, regional
502     model etc..
503     Configured for verification/exp2 - 4 degree global, two process.
504    
505    checkpoint7
506     Created by cnh
507     Simple 4 degree global simulation
508     configuration.
509     Includes climatological wind,
510     hydrography, bathymetry etc
511     Does not include Heat Flux and E-P
512    
513    checkpoint6
514     Created by cnh
515     merged checkpoint5 with CD and
516     spherical polar code.
517     Still some problems with GM Redi
518     abd full topography.
519    
520    checkpoint5
521     Created by AJA
522     contains updates to GM Redi
523     and reordered timestepping loop
524     for Implicit Diffusion.
525    
526    checkpoint4
527     Created by cnh
528     Contains memory saving macros ( _rdxc etc..) for when
529     grid variations are limited.
530     Contains polynomial coeffs for EOS and knudsen program
531     for generation.
