89    o added multi-dimensional advection method for tracers
90      
91    checkpoint40pre8
92    o new package rw/
93      Added method for dumping intermediate local arrays:
94      mdsio_writetile - same as mdsio_writefield except works from inside
95                        bi,bj loop
96      mdsio_writelocal - same as mdsio_writetile except works for local
97                         arrays
98      write_local_r? - higher-level wrapper for mdsio_writelocal
99      Controlled by diagFreq. Defaults to zero (ie. no dumps)
100      Example given at end of mom_vecinv.F that dumps some local arrays.
101    o replaced calc_mom_rhs.F by mom_fluxform.F/mom_vecinc.F to
102      control flux-form versus vector invariant code.
103      Switch is runtime flag vectorInvariantMomentum (defaults to false)
104      or genmake -DISABLE ...
105    o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
106      (additional storing is now needed for case vecinv;
107      currently nothing implemented to switch this storing off
108      in case fluxform is used since no CPP flag available).
109    
110    checkpoint40pre7
111    o bug fix in dynamics.F
112      calc_viscosity called before k=1,Nr loop.
113    o added some #ifdef's ALLOW_PASSIVE_TRACER
114    o cleaned initialisations in ctrl_map_ini
115      related to TAF
116

118    o split dynamics into thermodynamics & dynamics
119    o corresponding split of calc_diffusivity into
120      calc_diffusivity, calc_viscosity
121      (kpp_calc_diff, kpp_calc_visc).
122    o Added diffkr, kapgm to control variables
123    o bug fix in gmredi_slope_limit for ldd97
124    
125    checkpoint40pre5
126    o proper initialization of Adams-Bashforth time stepping
127      + uses forward step for very first step of model (iter=0)
128    o re-generated *all* output since almost all output is modified by this
129      change (sorry but we've been putting this one off for about 2 years)
130      + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
131        *not* regenerated since they are already out of date and I don't
132        want to create the impression that they are suddenly working.
133    o removed KAP stuff for DEC's
134    o modified/added many .cvsignore files in */code and */input
135    o added new expt "solid-body.cs-32x32x1"
136      + this uses an alternative form of ini_curvilinear_grid.F which
137        is not necessarily any better than the current one...
138    
139    checkpoint40pre4
140    o added re-initialisations of utrans,vtrans,rtrans in
141      calc_common_factors which are crucial for TAF.
142    o extended iMin,jMin range for calc_common_factors,
143      calc_diffusivity
144    o added option ALLOW_PASSIVE_TRACER
145    o a few minor updates and fixes
146    
147    checkpoint40pre3
148    o created calc_gtr1.F for gad package
149    o split the_main_loop and re-introduced forward_step

151    
152    checkpoint40pre2
153    o Updated to latest branch of AJA, JMC
154    o Added gradient check package
155    o Added routines for passive tracer handling
156    o Added carbon sequestration sensitivity experiment
157    
158    checkpoint39
159     o Modifications and fixes to support TAMC
160       (mainly missing or wrong directives)
161     o Corrected common blocks when fooling TAMC to produce adjoint I/O
162       in addummy_in_stepping
163     o Updated verification/vero/ (bug fixes in code/, correct pickups in input/)
164     o Enabled "sliced" (xz-,yz-) exchanges, needed for obcs.
165     o Included following packages:
166       cal: calendar
167       exf: external forcing
168       ecco: essential routines to control use of cal, exf
169             (NB: this is not the full ECCO environment)
170     o disabled some packages by default in genmake
171    
172    checkpoint38
173     o see notes_c37_adj.txt
174     o corrected wrong layer index in external_forcing_t
175     o replaced the_main_loop/forward_step by the_main_loop
176     o removed forceoutput from write_state
177       (replaced criteria for initial/final state)
178     o added runtime flag for pre-C35 pickups: usePickupBeforeC35
179    
180    checkpoint37
181     o mdsio.F routine split and packaged in pkg/mdsio
182       (mdsio.F and mdsio_gl.F still exist in eesupp/src but are not
183        used unless genmake -disable=mdsio)
184     o allow a more precise surface-geopotential gradient for the atmosphere
185       taking into account the change in space of Alpha (=1/rho) at the surface.
186     o variable "etaN" (replace cg2d_x) is the surface R-anomaly [r unit]
187       (ocean: sea surface height [m] / atmos: surface pressure anomaly [Pa])
188     o Change units: Phi_Hydrostatic (=phiHyd), Phi_Surface(=cg2d_x) and
189       Phi_NonHydrostatic (=cg3d_x), all have now the dimension of a potential
190       [m2/s2] (pressure/rhoConst in the ocean ; Geo-Potential in the atmosphere).
191     o Time-Average diagnostics defined as a pseudo package "timeave".
192     o pickup files : old pickup (before c35) did not work with new code (c35
193       and after) unless activating 2 commented lines in initialise-varia.
194     o Non-Hydrostatic pickup file Pb fixed.
195     o bug with Rigid-lid version (since c35) fixed.  
196    
197    checkpoint36
198     o implement Crank-Nickelson barotropic time-stepping
199     o recover Time-Average diagnostics
200     o fix Pb in checkpoint (PR#19)
201     o AIM become a standard package ; clean unused CPP_kees
202    
203    checkpoint35
204     o subtantial rewrite of dynamics.f
205     o allows staggered time-stepping
206     o packaged obcs, aim (Atmospheric Physics), zonal_filt, shap_filt
207     o added bottom drag (linear + quadratic)
208    
209    checkpoint34
210     o Modified exchange routines for correct reverse simulation.
211     o Added verification output to comply with bug fix in impldiff.F
212       as of c33 (exp2, natl_box).
213     o Corrected store directives in dynamics.F
214     o Corrected array boundaries in impldiff.F
215     o Corrected array dimensions in gmredi.
216       Added temporary scalars to avoid storage by TAMC (gmredi, kpp).
217     o Added routine GLOBAL_SUM_INT to global_sum.F
218     o Added mdsio_gl.F for ECCO purposes.
219    
220    checkpoint33
221     o Fixed bug in lower BC in impldiff.F
222     o Fixed confusion about units of forcing arrays in FFIELDS.h
223       namely Fu,Fv,Qnet,Qsw,EmPmR:
224       - Removed verification/natl_box/code/external_fields_scale.F
225         (did not differ from that in model/src)
226       - Changed units of fu,fv,Qnet,Qsw,EmPmR back to proper units
227         (see FFIELDS.h for description)
228       - Scale fu,fv,Qnet,Qsw,EmPmR when used in external_forcing_surf.F,
229         kpp_calc.F and kpp_transport_t.F
230       - Removed model/src/external_fields_scale.F and calls to it
231       - verification/natl_box uses flux data with "atmospheric" sign so
232         a special version of external_fields_load.F is used to
233         change the data as it's read in. This way, the arrays
234         have the right units and signs at all times tha a user could
235         possibly use them.
236     o Corrected genmake to delete a temporary file during configuration
237    
238    checkpoint32
239     o Scaling of forcing fields moved from external_forcing.F to
240       external_fields_scale.F, called directly after loading fields.
241     o Surface relaxation terms added to surface tendency fields in
242       extra subroutine.
243     o impldiff.F changed to avoid storing by TAMC of huge intermediate
244       fields.
245     o Changes in GMRedi to comply with packaging structure.
246     o Modifications and bug fixes in KPP package.
247     o Verification experiment for KPP added (verification/nat_box/)
248    
249    checkpoint31
250     o Packages interface brought in line with defined standard
251       -> new routines packages_...F
252       -> changes in initialise_fixed.F, initialise_varia.F
253       -> enables initialisation interface for ECCO package
254     o Rescaling of external forcing fields immediately after read
255       (removed from external_forcing.F)
256       -> new: surface_fields_scale.F
257       -> affects ini_foorcing.F, external_fields_load.F
258     o Computation of surface tendencies before tendency updates.
259       -> new: external_forcing_surf.F
260     o Change of variable names useGMRedi, useKPP, useECCO
261     o Further changes in dynamics.F, impldiff.F for TAMC
262     o Tested for experiments 0, 2, 4.
263       - not yet tested for GMRedi.
264       - not yet tested for KPP.
265    
266    checkpoint30
267     o Updates for OBCs
268     o New experiment for test OBCs (internal_wave)

270     o Updates for KPP: calculation of viscosity corrected, new variables
271       kpp_dumpFreq and kpp_taveFreq
272     o CPP'd calls to system routines for TARGET_CRAY_VECTOR (P.H.)
273       and entry for T90 in genmake
274    
275    checkpoint29

277    
278    checkpoint28
279     o Corrected initialization of hFacMin for difference vertical coordinates
280     o Modified calculation of partial cell thickness to more robust algorithm
281     o config_summary.F: replaced write_1D_... by write_0D_...
282       read_write.F: added subroutines write_0D_...
283     o routines calc_common_factors, calc_gs, calc_gt, calc_phi_hyd, find_rho:
284       included some initialisations required for TAMC.
285     o routine calc_isoslopes: modified sqrt computation to make it
286       differentiable for zero argument.
287     o routines dynamics, impldiff:
288       included store directives and tape key computations required for TAMC.
289     o ALL TAMC related changes are between ifdef ALLOW_AUTODIFF_TAMC
290    
291    checkpoint27
292     o fixed calc_isoslopes() to so that cancellation of terms in tensor
293       formulation works properly with variable resolution.
294     o restructured the calling tree between the_model_main() and dynamics()
295     o split initialise() into initialise_fixed() and initialise_varia()

298    
299    checkpoint26
300     o moved some #ifdef in optional routines to encompass everything
301       except the argument declarations. This was using up some memory.
302     o fixed macros like _ADT to work with both versions of Linux cpp
303     o cleaned up some unused and uninitialized variables
304       (helps when debugging with strict compile options)
305     o split up CPP_EEOPTIONS.h into options and macros
306       (macros are now in eesupp/inc/CPP_EEMACROS.h)
307     o patch for 2 processor JAM mode
308    
309    checkpoint25
310     o updates for OBCs and NH
311     o dramatically reduced memory usage
312     o added "JAM" routines for use on Artic network
313     o parameterization of convection by implicit vertical diffusion
314     o added a diagnostic of convective index
315     o moved call to calc_divg_hat() from dynamics() to solve_for_pressure()
316       (this is was partly for OBCs and NH but also in anticipation of
317        an explicit free-surface option)

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

366       accumulation in reverse mode. Adjoint of an
367       assignment is an addition.
368     o Changes to support compilation by TAMC (LR(1)
369       syntax) and by g77 under Linux ( 72 character
370       limit ).
371    
372    checkpoint15
373     Rewrote exchange routines to allow
374     o General tile <-> tile connectivity.

376     o Variable width overlap and exchange region widths.
377     o Hooks for sharing data via DMA, Arctic, Memory Channel,
378       shmput/shmget, VIA, SYSV shmem and every other cool
379       communication method.
380    
381    checkpoint14
382     Consistent isomorphism chages made. These allow dynamical core
383     to support both pressure and meters as a vertical coordinate.
384    
385    checkpoint13
386     Release which corrects global_max problem and a couple
387     of KGM time-averaging diagnostic errors. Also contains
388     a double-gyre experiment setup as well as the baseline
389     4 degree global template. The double gyre template is
390     organised to allow it to be applied automatically to
391     the baseline configuration.
392    
393    branch-point-rdot
394     A few tidy-ups have been made bt the real point of this
395     check-point (excuse the pun) is to allow a branch to be
396     made for the purposes of adding the rDot alterations.
397     I don't want to commit the rDot to the main-trunk until
398     we've actually tested it...
399
