3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    
6    o argument futureIter of S/R obcs_calc missing in exp4 & internal_wave /code
7    o solve_for_pressure : set cg2d_x to zero where OBCS are applied
8    
9    checkpoint44h_post = checkpoint45
10    o Fix to restore differentiability:
11      place at which packages_init_variables is called in
12      initialise_varia is crucial for reverse control flow.
13    o modifications in GMRedi to enable stable adjoint
14      (corresponding modif's in thermodynamics, dynamics)
15    o added missing hook for sponge layer code in external_forcing
16    o modified test cost functions
17    o storing in gad_advection (plus removal of write(0,*)!
18    o missing headers TR1.h added in convective_adjustment routines
19    o errorMessageUnit set non-equal zero in eeboot
20      (conflict on some platforms, e.g. IBM SP3)
21    o modified carbon verif.
22    
23    checkpoint44h_pre
24    o vertical grid option: allow to put the Interface at the middle between
25      2 cell-centers ; replace delZ in pkg/kpp by drF.
26    o GM Advective form: Tracers are advected using the residual transport (=
27      Euler+GM-bolus); set param GM_AdvSeparate=T to return to previous form.
28    
29    checkpoint44g_post
30    o fix surface correction term in multiDimAdvection (affects plume_on_slope
31      results) ; ifdef missing in thermodynamics.F
32    
33    checkpoint44f_pre,checkpoint44f_post
34    o added PTRACERS package
35      This allows an arbitrary number of passive tracers to be integrated
36      forward simultaneously with the dynamicaly model.
37      + Implemented so far:
38        - basic forward algorithm (time-stepping, advection, diffusion, convection)
39        - I/O and checkpointing
40        - GM/Redi  *but*  using the GM/Redi coefficient of Salt
41      + Not implemented so far:
42        - KPP
43        - OBCS
44      + No specific example supplied (yet) but global_ocean.90x40x15 has the
45        necessary data.ptracer file. Simply use -enable=ptracers and uncomment
46        line in data.pkg.
47      + This package is disabled by default since it increases storage.
48    
49    
50    o testscript: added -cleanup option
51    o Shap_filt: a) new shap_filt S/R to use no-slip BC with S2 filter
52                 b) enable to filter 2D fields.
53    
54    checkpoint44e_pre,post
55    o re-wrote convective adjustment to use pre-calculated weights

57      Adds:    model/src/convective_weights.F, convectively_mixtracer.F
58      Original calls to convect() still in place.
59    
60    chkpt44d_pre,post
61    o added missing EXCLUDE_MONITOR flags
62    o changed "e" to "_d" in gmredi_slope_limit, gmredi_slope_psi
63      (incompatible typ in MIN/MAX expressions caused problems
64      on IBM SP3)
65    o in genmake added variable MAKEDEPEND
66      plus resetting for case SunOS
67    o added timer_stats.c routine for IBM SP3
68    o removed variables in dynamics

71    
72    o real fresh water flux implemented with non-linear free-surface.
73    
74    chkpt44c_pre,post
75    o few fix (mask in shap_s2, EmPmR in external_field_load,
76      USE_NATURAL_BCS in solve_for_P);
77    o add arguments myIter & myTime to S/R obcs_calc & solve_for_P
78

109      Fixed AD-related problems:
110    o Store directives up-to-date with re-arranged Adams-Bashforth
111      (mainly thermodynamics.F)
112    o New store directives for multi-dim. advection schemes
113      * new CPP flag ALLOW_MULTI_DIM_ADVECTION
114      * new common block and key passkey

118    o Cleaned argument list for timestep_tracer.F
119    
120    checkpoint41
121    o re-formatted/added comments in prologues of key subroutines
122      to work with protex
123    
124    checkpoint40
125    o moved calc_gs, calc_gt and calc_tr1 back to model/src
126    o added FLT (floats) package from Arne along with demo. experiment
127    o re-arranged Adams-Bashforth scheme for tracers to allow easier

139    o changes to commenting of arguments for TAF/TAMC
140    o added/updated many matlab scripts
141    o added multi-dimensional advection method for tracers
142      
143    checkpoint40pre8
144    o new package rw/
145      Added method for dumping intermediate local arrays:
146      mdsio_writetile - same as mdsio_writefield except works from inside
147                        bi,bj loop
148      mdsio_writelocal - same as mdsio_writetile except works for local
149                         arrays
150      write_local_r? - higher-level wrapper for mdsio_writelocal
151      Controlled by diagFreq. Defaults to zero (ie. no dumps)
152      Example given at end of mom_vecinv.F that dumps some local arrays.
153    o replaced calc_mom_rhs.F by mom_fluxform.F/mom_vecinc.F to
154      control flux-form versus vector invariant code.
155      Switch is runtime flag vectorInvariantMomentum (defaults to false)
156      or genmake -DISABLE ...
157    o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
158      (additional storing is now needed for case vecinv;
159      currently nothing implemented to switch this storing off
160      in case fluxform is used since no CPP flag available).
161    
162    checkpoint40pre7
163    o bug fix in dynamics.F
164      calc_viscosity called before k=1,Nr loop.
165    o added some #ifdef's ALLOW_PASSIVE_TRACER
166    o cleaned initialisations in ctrl_map_ini
167      related to TAF
168

170    o split dynamics into thermodynamics & dynamics
171    o corresponding split of calc_diffusivity into
172      calc_diffusivity, calc_viscosity
173      (kpp_calc_diff, kpp_calc_visc).
174    o Added diffkr, kapgm to control variables
175    o bug fix in gmredi_slope_limit for ldd97
176    
177    checkpoint40pre5
178    o proper initialization of Adams-Bashforth time stepping
179      + uses forward step for very first step of model (iter=0)
180    o re-generated *all* output since almost all output is modified by this
181      change (sorry but we've been putting this one off for about 2 years)
182      + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
183        *not* regenerated since they are already out of date and I don't
184        want to create the impression that they are suddenly working.
185    o removed KAP stuff for DEC's
186    o modified/added many .cvsignore files in */code and */input
187    o added new expt "solid-body.cs-32x32x1"
188      + this uses an alternative form of ini_curvilinear_grid.F which
189        is not necessarily any better than the current one...
190    
191    checkpoint40pre4
192    o added re-initialisations of utrans,vtrans,rtrans in
193      calc_common_factors which are crucial for TAF.
194    o extended iMin,jMin range for calc_common_factors,
195      calc_diffusivity
196    o added option ALLOW_PASSIVE_TRACER
197    o a few minor updates and fixes
198    
199    checkpoint40pre3
200    o created calc_gtr1.F for gad package
201    o split the_main_loop and re-introduced forward_step
202    o some recomputations of nIter0 for TAMC
203    
204    checkpoint40pre2
205    o Updated to latest branch of AJA, JMC
206    o Added gradient check package
207    o Added routines for passive tracer handling
208    o Added carbon sequestration sensitivity experiment
209    
210    checkpoint39
211     o Modifications and fixes to support TAMC
212       (mainly missing or wrong directives)
213     o Corrected common blocks when fooling TAMC to produce adjoint I/O
214       in addummy_in_stepping
215     o Updated verification/vero/ (bug fixes in code/, correct pickups in input/)
216     o Enabled "sliced" (xz-,yz-) exchanges, needed for obcs.
217     o Included following packages:
218       cal: calendar
219       exf: external forcing
220       ecco: essential routines to control use of cal, exf
221             (NB: this is not the full ECCO environment)
222     o disabled some packages by default in genmake
223    
224    checkpoint38
225     o see notes_c37_adj.txt
226     o corrected wrong layer index in external_forcing_t
227     o replaced the_main_loop/forward_step by the_main_loop
228     o removed forceoutput from write_state
229       (replaced criteria for initial/final state)
230     o added runtime flag for pre-C35 pickups: usePickupBeforeC35
231    
232    checkpoint37
233     o mdsio.F routine split and packaged in pkg/mdsio
234       (mdsio.F and mdsio_gl.F still exist in eesupp/src but are not
235        used unless genmake -disable=mdsio)
236     o allow a more precise surface-geopotential gradient for the atmosphere
237       taking into account the change in space of Alpha (=1/rho) at the surface.
238     o variable "etaN" (replace cg2d_x) is the surface R-anomaly [r unit]
239       (ocean: sea surface height [m] / atmos: surface pressure anomaly [Pa])
240     o Change units: Phi_Hydrostatic (=phiHyd), Phi_Surface(=cg2d_x) and
241       Phi_NonHydrostatic (=cg3d_x), all have now the dimension of a potential
242       [m2/s2] (pressure/rhoConst in the ocean ; Geo-Potential in the atmosphere).
243     o Time-Average diagnostics defined as a pseudo package "timeave".
244     o pickup files : old pickup (before c35) did not work with new code (c35
245       and after) unless activating 2 commented lines in initialise-varia.
246     o Non-Hydrostatic pickup file Pb fixed.
247     o bug with Rigid-lid version (since c35) fixed.  
248    
249    checkpoint36
250     o implement Crank-Nickelson barotropic time-stepping
251     o recover Time-Average diagnostics
252     o fix Pb in checkpoint (PR#19)
253     o AIM become a standard package ; clean unused CPP_kees
254    
255    checkpoint35
256     o subtantial rewrite of dynamics.f
257     o allows staggered time-stepping
258     o packaged obcs, aim (Atmospheric Physics), zonal_filt, shap_filt
259     o added bottom drag (linear + quadratic)
260    
261    checkpoint34
262     o Modified exchange routines for correct reverse simulation.
263     o Added verification output to comply with bug fix in impldiff.F
264       as of c33 (exp2, natl_box).
265     o Corrected store directives in dynamics.F
266     o Corrected array boundaries in impldiff.F
267     o Corrected array dimensions in gmredi.
268       Added temporary scalars to avoid storage by TAMC (gmredi, kpp).
269     o Added routine GLOBAL_SUM_INT to global_sum.F
270     o Added mdsio_gl.F for ECCO purposes.
271    
272    checkpoint33
273     o Fixed bug in lower BC in impldiff.F
274     o Fixed confusion about units of forcing arrays in FFIELDS.h
275       namely Fu,Fv,Qnet,Qsw,EmPmR:
276       - Removed verification/natl_box/code/external_fields_scale.F
277         (did not differ from that in model/src)
278       - Changed units of fu,fv,Qnet,Qsw,EmPmR back to proper units
279         (see FFIELDS.h for description)
280       - Scale fu,fv,Qnet,Qsw,EmPmR when used in external_forcing_surf.F,
281         kpp_calc.F and kpp_transport_t.F
282       - Removed model/src/external_fields_scale.F and calls to it
283       - verification/natl_box uses flux data with "atmospheric" sign so
284         a special version of external_fields_load.F is used to
285         change the data as it's read in. This way, the arrays
286         have the right units and signs at all times tha a user could
287         possibly use them.
288     o Corrected genmake to delete a temporary file during configuration
289    
290    checkpoint32
291     o Scaling of forcing fields moved from external_forcing.F to
292       external_fields_scale.F, called directly after loading fields.
293     o Surface relaxation terms added to surface tendency fields in
294       extra subroutine.
295     o impldiff.F changed to avoid storing by TAMC of huge intermediate
296       fields.
297     o Changes in GMRedi to comply with packaging structure.
298     o Modifications and bug fixes in KPP package.
299     o Verification experiment for KPP added (verification/nat_box/)
300    
301    checkpoint31
302     o Packages interface brought in line with defined standard
303       -> new routines packages_...F
304       -> changes in initialise_fixed.F, initialise_varia.F
305       -> enables initialisation interface for ECCO package
306     o Rescaling of external forcing fields immediately after read
307       (removed from external_forcing.F)
308       -> new: surface_fields_scale.F
309       -> affects ini_foorcing.F, external_fields_load.F
310     o Computation of surface tendencies before tendency updates.
311       -> new: external_forcing_surf.F
312     o Change of variable names useGMRedi, useKPP, useECCO
313     o Further changes in dynamics.F, impldiff.F for TAMC
314     o Tested for experiments 0, 2, 4.
315       - not yet tested for GMRedi.
316       - not yet tested for KPP.
317    
318    checkpoint30
319     o Updates for OBCs
320     o New experiment for test OBCs (internal_wave)
321     o New output.txt in verification/exp4/results/
322     o Updates for KPP: calculation of viscosity corrected, new variables
323       kpp_dumpFreq and kpp_taveFreq
324     o CPP'd calls to system routines for TARGET_CRAY_VECTOR (P.H.)
325       and entry for T90 in genmake
326    
327    checkpoint29

329    
330    checkpoint28
331     o Corrected initialization of hFacMin for difference vertical coordinates
332     o Modified calculation of partial cell thickness to more robust algorithm
333     o config_summary.F: replaced write_1D_... by write_0D_...
334       read_write.F: added subroutines write_0D_...
335     o routines calc_common_factors, calc_gs, calc_gt, calc_phi_hyd, find_rho:
336       included some initialisations required for TAMC.
337     o routine calc_isoslopes: modified sqrt computation to make it
338       differentiable for zero argument.
339     o routines dynamics, impldiff:
340       included store directives and tape key computations required for TAMC.
341     o ALL TAMC related changes are between ifdef ALLOW_AUTODIFF_TAMC
342    
343    checkpoint27
344     o fixed calc_isoslopes() to so that cancellation of terms in tensor
345       formulation works properly with variable resolution.
346     o restructured the calling tree between the_model_main() and dynamics()
347     o split initialise() into initialise_fixed() and initialise_varia()
348     o introduced initialization file pSurfInitFile for free surface (cg2d_x)
349       in new routine ini_psurf()
350    
351    checkpoint26
352     o moved some #ifdef in optional routines to encompass everything
353       except the argument declarations. This was using up some memory.
354     o fixed macros like _ADT to work with both versions of Linux cpp
355     o cleaned up some unused and uninitialized variables
356       (helps when debugging with strict compile options)
357     o split up CPP_EEOPTIONS.h into options and macros
358       (macros are now in eesupp/inc/CPP_EEMACROS.h)
359     o patch for 2 processor JAM mode
360    
361    checkpoint25
362     o updates for OBCs and NH
363     o dramatically reduced memory usage
364     o added "JAM" routines for use on Artic network
365     o parameterization of convection by implicit vertical diffusion
366     o added a diagnostic of convective index
367     o moved call to calc_divg_hat() from dynamics() to solve_for_pressure()
368       (this is was partly for OBCs and NH but also in anticipation of
369        an explicit free-surface option)
370     o initial state input files for U and V
371    
372    checkpoint24
373     o Removed some spurious "REAL"s

380    
381    checkpoint22
382     o Made many small changes: implicit none, format(i5), etc...

384    
385    checkpoint21
386     o Introduced new I/O package that supports direct-access records (mdsio.F)
387     o Split-up mid-level I/O routines
388     o Updated input data for experiments 0,1,2,4 and 5

390    
391    checkpoint20
392     o Tidied up open-boundaries some more
393     o Added non-hydrostatic code
394     o Fixed some input data
395     o Modified MPI start-up to work in "coupled" context.

400     o Corrected advective terms near boundaries.
401     o Added CPP flag for "old UV" geometry and corrected spherical geometry.
402     o Implemented free-slip/no-slip BCs and del^4 dissipation.
403     o Split default parameters out of ini_parms.F into set_defaults.F.
404    
405    checkpoint18
406     o Further changes for optional code generation with
407       CPP - ugh!
408    
409    checkpoint17
410     o Beginning to incorporating modularity
411       for supporting atmos. and ocean configs.
412     o Small changes for TAMC complinace
413     o New ultra simple test case. Barotropic box
414       configuration "exp0".
415    
416    checkpoint16
417     o Minor changes to exchange routines to support
418       accumulation in reverse mode. Adjoint of an
419       assignment is an addition.
420     o Changes to support compilation by TAMC (LR(1)
421       syntax) and by g77 under Linux ( 72 character
422       limit ).
423    
424    checkpoint15
425     Rewrote exchange routines to allow
426     o General tile <-> tile connectivity.
427     o TAMC reverse mode flag ( is this really needed? )
428     o Variable width overlap and exchange region widths.
429     o Hooks for sharing data via DMA, Arctic, Memory Channel,
430       shmput/shmget, VIA, SYSV shmem and every other cool
431       communication method.
432    
433    checkpoint14
434     Consistent isomorphism chages made. These allow dynamical core
435     to support both pressure and meters as a vertical coordinate.
436    
437    checkpoint13
438     Release which corrects global_max problem and a couple
439     of KGM time-averaging diagnostic errors. Also contains
440     a double-gyre experiment setup as well as the baseline
441     4 degree global template. The double gyre template is
442     organised to allow it to be applied automatically to
443     the baseline configuration.
444    
445    branch-point-rdot
446     A few tidy-ups have been made bt the real point of this
447     check-point (excuse the pun) is to allow a branch to be
448     made for the purposes of adding the rDot alterations.
