10    o monitor: change definition of KE to check conservation of Energy
11    
12    checkpoint45c_post
13    o Removed f90 comments ("!")
14    o Modified initialisations to enable exf package for MITgcm
15      (without invoking ECCO_PACKAGE).
16    o modifications to gradient check package (Martin Losch)
17      - enable centered differences
18      - modified format of standard output
19    
20    checkpoint45b_post
21    o cleaned exchange calls in cg2d

36    o solve_for_pressure : set cg2d_x to zero where OBCS are applied
37    
38    checkpoint44h_post = checkpoint45
39    o Fix to restore differentiability:
40      place at which packages_init_variables is called in

60      results) ; ifdef missing in thermodynamics.F
61    
62    checkpoint44f_pre,checkpoint44f_post
63    o added PTRACERS package
64      This allows an arbitrary number of passive tracers to be integrated
65      forward simultaneously with the dynamicaly model.
66      + Implemented so far:
67        - basic forward algorithm (time-stepping, advection, diffusion, convection)
68        - I/O and checkpointing
69        - GM/Redi  *but*  using the GM/Redi coefficient of Salt
70      + Not implemented so far:
71        - KPP
72        - OBCS
73      + No specific example supplied (yet) but global_ocean.90x40x15 has the
74        necessary data.ptracer file. Simply use -enable=ptracers and uncomment
75        line in data.pkg.
76      + This package is disabled by default since it increases storage.
77    
78    
79    o testscript: added -cleanup option
80    o Shap_filt: a) new shap_filt S/R to use no-slip BC with S2 filter

102    
103    chkpt44c_pre,post
104    o few fix (mask in shap_s2, EmPmR in external_field_load,
105      USE_NATURAL_BCS in solve_for_P);
106    o add arguments myIter & myTime to S/R obcs_calc & solve_for_P
107    
108    checkpoint44b_pre/_post

138      Fixed AD-related problems:
139    o Store directives up-to-date with re-arranged Adams-Bashforth
140      (mainly thermodynamics.F)
141    o New store directives for multi-dim. advection schemes
142      * new CPP flag ALLOW_MULTI_DIM_ADVECTION

150    o re-formatted/added comments in prologues of key subroutines
151      to work with protex
152    
153    checkpoint40
154    o moved calc_gs, calc_gt and calc_tr1 back to model/src
155    o added FLT (floats) package from Arne along with demo. experiment

170    o added multi-dimensional advection method for tracers
171      
172    checkpoint40pre8
173    o new package rw/
174      Added method for dumping intermediate local arrays:
175      mdsio_writetile - same as mdsio_writefield except works from inside
176                        bi,bj loop
177      mdsio_writelocal - same as mdsio_writetile except works for local
178                         arrays
179      write_local_r? - higher-level wrapper for mdsio_writelocal
180      Controlled by diagFreq. Defaults to zero (ie. no dumps)
181      Example given at end of mom_vecinv.F that dumps some local arrays.
182    o replaced calc_mom_rhs.F by mom_fluxform.F/mom_vecinc.F to
183      control flux-form versus vector invariant code.
184      Switch is runtime flag vectorInvariantMomentum (defaults to false)
185      or genmake -DISABLE ...
186    o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
187      (additional storing is now needed for case vecinv;
188      currently nothing implemented to switch this storing off
189      in case fluxform is used since no CPP flag available).
190    
191    checkpoint40pre7
192    o bug fix in dynamics.F
193      calc_viscosity called before k=1,Nr loop.

200    o corresponding split of calc_diffusivity into
201      calc_diffusivity, calc_viscosity
202      (kpp_calc_diff, kpp_calc_visc).
203    o Added diffkr, kapgm to control variables
204    o bug fix in gmredi_slope_limit for ldd97
205    
206    checkpoint40pre5
207    o proper initialization of Adams-Bashforth time stepping
208      + uses forward step for very first step of model (iter=0)
209    o re-generated *all* output since almost all output is modified by this
210      change (sorry but we've been putting this one off for about 2 years)
211      + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
212        *not* regenerated since they are already out of date and I don't
213        want to create the impression that they are suddenly working.
214    o removed KAP stuff for DEC's
215    o modified/added many .cvsignore files in */code and */input
216    o added new expt "solid-body.cs-32x32x1"
217      + this uses an alternative form of ini_curvilinear_grid.F which
218        is not necessarily any better than the current one...
219    
220    checkpoint40pre4
221    o added re-initialisations of utrans,vtrans,rtrans in
222      calc_common_factors which are crucial for TAF.

235    o Added gradient check package
236    o Added routines for passive tracer handling
237    o Added carbon sequestration sensitivity experiment
238    
239    checkpoint39
240     o Modifications and fixes to support TAMC
241       (mainly missing or wrong directives)

243       in addummy_in_stepping
244     o Updated verification/vero/ (bug fixes in code/, correct pickups in input/)
245     o Enabled "sliced" (xz-,yz-) exchanges, needed for obcs.
246     o Included following packages:
247       cal: calendar
248       exf: external forcing
249       ecco: essential routines to control use of cal, exf
250             (NB: this is not the full ECCO environment)
251     o disabled some packages by default in genmake
252    
253    checkpoint38
254     o see notes_c37_adj.txt
255     o corrected wrong layer index in external_forcing_t
256     o replaced the_main_loop/forward_step by the_main_loop
257     o removed forceoutput from write_state
258       (replaced criteria for initial/final state)
259     o added runtime flag for pre-C35 pickups: usePickupBeforeC35
260    
261    checkpoint37
262     o mdsio.F routine split and packaged in pkg/mdsio
263       (mdsio.F and mdsio_gl.F still exist in eesupp/src but are not
264        used unless genmake -disable=mdsio)
265     o allow a more precise surface-geopotential gradient for the atmosphere
266       taking into account the change in space of Alpha (=1/rho) at the surface.
267     o variable "etaN" (replace cg2d_x) is the surface R-anomaly [r unit]
268       (ocean: sea surface height [m] / atmos: surface pressure anomaly [Pa])
269     o Change units: Phi_Hydrostatic (=phiHyd), Phi_Surface(=cg2d_x) and
270       Phi_NonHydrostatic (=cg3d_x), all have now the dimension of a potential
271       [m2/s2] (pressure/rhoConst in the ocean ; Geo-Potential in the atmosphere).
272     o Time-Average diagnostics defined as a pseudo package "timeave".
273     o pickup files : old pickup (before c35) did not work with new code (c35
274       and after) unless activating 2 commented lines in initialise-varia.
275     o Non-Hydrostatic pickup file Pb fixed.
276     o bug with Rigid-lid version (since c35) fixed.  
277    
278    checkpoint36
279     o implement Crank-Nickelson barotropic time-stepping
280     o recover Time-Average diagnostics
281     o fix Pb in checkpoint (PR#19)
282     o AIM become a standard package ; clean unused CPP_kees
283    
284    checkpoint35
285     o subtantial rewrite of dynamics.f
286     o allows staggered time-stepping
287     o packaged obcs, aim (Atmospheric Physics), zonal_filt, shap_filt
288     o added bottom drag (linear + quadratic)
289    
290    checkpoint34
291     o Modified exchange routines for correct reverse simulation.
292     o Added verification output to comply with bug fix in impldiff.F
293       as of c33 (exp2, natl_box).
294     o Corrected store directives in dynamics.F
295     o Corrected array boundaries in impldiff.F
296     o Corrected array dimensions in gmredi.
297       Added temporary scalars to avoid storage by TAMC (gmredi, kpp).
298     o Added routine GLOBAL_SUM_INT to global_sum.F
299     o Added mdsio_gl.F for ECCO purposes.
300    
301    checkpoint33
302     o Fixed bug in lower BC in impldiff.F
303     o Fixed confusion about units of forcing arrays in FFIELDS.h
304       namely Fu,Fv,Qnet,Qsw,EmPmR:
305       - Removed verification/natl_box/code/external_fields_scale.F
306         (did not differ from that in model/src)
307       - Changed units of fu,fv,Qnet,Qsw,EmPmR back to proper units
308         (see FFIELDS.h for description)
309       - Scale fu,fv,Qnet,Qsw,EmPmR when used in external_forcing_surf.F,
310         kpp_calc.F and kpp_transport_t.F
311       - Removed model/src/external_fields_scale.F and calls to it
312       - verification/natl_box uses flux data with "atmospheric" sign so
313         a special version of external_fields_load.F is used to
314         change the data as it's read in. This way, the arrays
315         have the right units and signs at all times tha a user could
316         possibly use them.
317     o Corrected genmake to delete a temporary file during configuration
318    
319    checkpoint32
320     o Scaling of forcing fields moved from external_forcing.F to
321       external_fields_scale.F, called directly after loading fields.
322     o Surface relaxation terms added to surface tendency fields in
323       extra subroutine.

325       fields.
326     o Changes in GMRedi to comply with packaging structure.
327     o Modifications and bug fixes in KPP package.
328     o Verification experiment for KPP added (verification/nat_box/)

331     o Packages interface brought in line with defined standard
332       -> new routines packages_...F
333       -> changes in initialise_fixed.F, initialise_varia.F
334       -> enables initialisation interface for ECCO package
335     o Rescaling of external forcing fields immediately after read
336       (removed from external_forcing.F)
337       -> new: surface_fields_scale.F
338       -> affects ini_foorcing.F, external_fields_load.F
339     o Computation of surface tendencies before tendency updates.
340       -> new: external_forcing_surf.F
341     o Change of variable names useGMRedi, useKPP, useECCO
342     o Further changes in dynamics.F, impldiff.F for TAMC
343     o Tested for experiments 0, 2, 4.
344       - not yet tested for GMRedi.
345       - not yet tested for KPP.
346    
347    checkpoint30
348     o Updates for OBCs
349     o New experiment for test OBCs (internal_wave)

358    
359    checkpoint28
360     o Corrected initialization of hFacMin for difference vertical coordinates
361     o Modified calculation of partial cell thickness to more robust algorithm
362     o config_summary.F: replaced write_1D_... by write_0D_...
363       read_write.F: added subroutines write_0D_...
364     o routines calc_common_factors, calc_gs, calc_gt, calc_phi_hyd, find_rho:
365       included some initialisations required for TAMC.
366     o routine calc_isoslopes: modified sqrt computation to make it
367       differentiable for zero argument.
368     o routines dynamics, impldiff:
369       included store directives and tape key computations required for TAMC.
370     o ALL TAMC related changes are between ifdef ALLOW_AUTODIFF_TAMC
371    
372    checkpoint27
373     o fixed calc_isoslopes() to so that cancellation of terms in tensor
374       formulation works properly with variable resolution.
375     o restructured the calling tree between the_model_main() and dynamics()
376     o split initialise() into initialise_fixed() and initialise_varia()

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

447       accumulation in reverse mode. Adjoint of an
448       assignment is an addition.
449     o Changes to support compilation by TAMC (LR(1)
450       syntax) and by g77 under Linux ( 72 character
451       limit ).
452    
453    checkpoint15
454     Rewrote exchange routines to allow
455     o General tile <-> tile connectivity.
456     o TAMC reverse mode flag ( is this really needed? )
457     o Variable width overlap and exchange region widths.
458     o Hooks for sharing data via DMA, Arctic, Memory Channel,
459       shmput/shmget, VIA, SYSV shmem and every other cool
460       communication method.
461    
462    checkpoint14
463     Consistent isomorphism chages made. These allow dynamical core
464     to support both pressure and meters as a vertical coordinate.
465    
466    checkpoint13
467     Release which corrects global_max problem and a couple
468     of KGM time-averaging diagnostic errors. Also contains
469     a double-gyre experiment setup as well as the baseline
470     4 degree global template. The double gyre template is
471     organised to allow it to be applied automatically to
472     the baseline configuration.
473    
474    branch-point-rdot
475     A few tidy-ups have been made bt the real point of this
476     check-point (excuse the pun) is to allow a branch to be
477     made for the purposes of adding the rDot alterations.
478     I don't want to commit the rDot to the main-trunk until
479     we've actually tested it...
480    
481    checkpoint12
482     Tidy up and added generic genmake script (formerly
483     configure script).
484     Released to testers.
485    
486    checkpoint11
487     Re-arranged initialise() and introduced ini_vertical_grid()
488     and ini_masks_etc().
489    
490    checkpoint10
491     Introduced the configure script.
492     Separated out the diags package.
493     Added template for writing time-averages of tile/intermediate quantities.
494     Updated SIZE.h in exp2 and made the data big-endian.
495    
496    checkpoint9
497     MPI fix. Filename changes (meta/data). salbin*y stuff.
498     General tidy-up.
499     SST.bin SSS.bin added to verification/exp2
500    
501    checkpoint8
502     Inludes time-dependant forcing and time-averaging.
503     Works at 4x4 and 2.8125x2.8125 global
504    
505    checkpoint7-4degree-ref
506     Branch from checkpoint7. Released for application to
507     global modeling and general modeling - process studies, regional
508     model etc..
509     Configured for verification/exp2 - 4 degree global, two process.
510    
511    checkpoint7
512     Created by cnh
513     Simple 4 degree global simulation
514     configuration.
515     Includes climatological wind,
516     hydrography, bathymetry etc
517     Does not include Heat Flux and E-P
