4      ==============================      ==============================
5    
6    checkpoint34
7     o Modified exchange routines for correct reverse simulation.
8     o Added verification output to comply with bug fix in impldiff.F
9       as of c33 (exp2, natl_box).
10     o Corrected store directives in dynamics.F
11     o Corrected array boundaries in impldiff.F
12     o Corrected array dimensions in gmredi.
13       Added temporary scalars to avoid storage by TAMC (gmredi, kpp).
14     o Added routine GLOBAL_SUM_INT to global_sum.F
15     o Added mdsio_gl.F for ECCO purposes.
16    
17    checkpoint33
18     o Fixed bug in lower BC in impldiff.F
19     o Fixed confusion about units of forcing arrays in FFIELDS.h
20       namely Fu,Fv,Qnet,Qsw,EmPmR:
21       - Removed verification/natl_box/code/external_fields_scale.F
22         (did not differ from that in model/src)
23       - Changed units of fu,fv,Qnet,Qsw,EmPmR back to proper units
24         (see FFIELDS.h for description)
25       - Scale fu,fv,Qnet,Qsw,EmPmR when used in external_forcing_surf.F,
26         kpp_calc.F and kpp_transport_t.F
27       - Removed model/src/external_fields_scale.F and calls to it
28       - verification/natl_box uses flux data with "atmospheric" sign so
29         a special version of external_fields_load.F is used to
30         change the data as it's read in. This way, the arrays
31         have the right units and signs at all times tha a user could
32         possibly use them.
33     o Corrected genmake to delete a temporary file during configuration
34    
35    checkpoint32
36     o Scaling of forcing fields moved from external_forcing.F to
37       external_fields_scale.F, called directly after loading fields.
38     o Surface relaxation terms added to surface tendency fields in
39       extra subroutine.
40     o impldiff.F changed to avoid storing by TAMC of huge intermediate
41       fields.
42     o Changes in GMRedi to comply with packaging structure.
43     o Modifications and bug fixes in KPP package.
44     o Verification experiment for KPP added (verification/nat_box/)
45    
46    checkpoint31
47     o Packages interface brought in line with defined standard
48       -> new routines packages_...F
49       -> changes in initialise_fixed.F, initialise_varia.F
50       -> enables initialisation interface for ECCO package
51     o Rescaling of external forcing fields immediately after read
52       (removed from external_forcing.F)
53       -> new: surface_fields_scale.F
54       -> affects ini_foorcing.F, external_fields_load.F
55     o Computation of surface tendencies before tendency updates.
56       -> new: external_forcing_surf.F
57     o Change of variable names useGMRedi, useKPP, useECCO
58     o Further changes in dynamics.F, impldiff.F for TAMC
59     o Tested for experiments 0, 2, 4.
60       - not yet tested for GMRedi.
61       - not yet tested for KPP.
62    
63    checkpoint30

67     o Updates for KPP: calculation of viscosity corrected, new variables
68       kpp_dumpFreq and kpp_taveFreq
69     o CPP'd calls to system routines for TARGET_CRAY_VECTOR (P.H.)

74    
75    checkpoint28
76     o Corrected initialization of hFacMin for difference vertical coordinates
77     o Modified calculation of partial cell thickness to more robust algorithm
78     o config_summary.F: replaced write_1D_... by write_0D_...
79       read_write.F: added subroutines write_0D_...
80     o routines calc_common_factors, calc_gs, calc_gt, calc_phi_hyd, find_rho:
81       included some initialisations required for TAMC.
82     o routine calc_isoslopes: modified sqrt computation to make it
83       differentiable for zero argument.
84     o routines dynamics, impldiff:
85       included store directives and tape key computations required for TAMC.
86     o ALL TAMC related changes are between ifdef ALLOW_AUTODIFF_TAMC
87    
88    checkpoint27
89     o fixed calc_isoslopes() to so that cancellation of terms in tensor
90       formulation works properly with variable resolution.
91     o restructured the calling tree between the_model_main() and dynamics()
92     o split initialise() into initialise_fixed() and initialise_varia()

94       in new routine ini_psurf()
95    
96    checkpoint26
97     o moved some #ifdef in optional routines to encompass everything
98       except the argument declarations. This was using up some memory.
99     o fixed macros like _ADT to work with both versions of Linux cpp
100     o cleaned up some unused and uninitialized variables
101       (helps when debugging with strict compile options)
102     o split up CPP_EEOPTIONS.h into options and macros
103       (macros are now in eesupp/inc/CPP_EEMACROS.h)
104     o patch for 2 processor JAM mode
105    
106    checkpoint25
107     o updates for OBCs and NH
108     o dramatically reduced memory usage
109     o added "JAM" routines for use on Artic network
110     o parameterization of convection by implicit vertical diffusion
111     o added a diagnostic of convective index
112     o moved call to calc_divg_hat() from dynamics() to solve_for_pressure()
113       (this is was partly for OBCs and NH but also in anticipation of
114        an explicit free-surface option)
115     o initial state input files for U and V
116    
117    checkpoint24
118     o Removed some spurious "REAL"s
119     o Updated KPP to latest version from JPL
120     o Added a COS(latitude) in horizontal viscosity

124     o Multiple minor fixes (implicit none's, arguments to global_sum, etc.)
125    
126    checkpoint22
127     o Made many small changes: implicit none, format(i5), etc...
128     o Introduced KPP mixing scheme (compiles and runs but *not* tested)
129    
130    checkpoint21
131     o Introduced new I/O package that supports direct-access records (mdsio.F)
132     o Split-up mid-level I/O routines
133     o Updated input data for experiments 0,1,2,4 and 5
134     o Finally removed the genmake.* scripts (everyone seems happy with genmake)
135    
136    checkpoint20
137     o Tidied up open-boundaries some more
138     o Added non-hydrostatic code
139     o Fixed some input data
140     o Modified MPI start-up to work in "coupled" context.
141

144     o Added new code for open boundaries.
145     o Corrected advective terms near boundaries.
146     o Added CPP flag for "old UV" geometry and corrected spherical geometry.
147     o Implemented free-slip/no-slip BCs and del^4 dissipation.
148     o Split default parameters out of ini_parms.F into set_defaults.F.
149    
150    checkpoint18
151     o Further changes for optional code generation with
152       CPP - ugh!
153    
154    checkpoint17
155     o Beginning to incorporating modularity
156       for supporting atmos. and ocean configs.
157     o Small changes for TAMC complinace
158     o New ultra simple test case. Barotropic box
159       configuration "exp0".
160    
161    checkpoint16
162     o Minor changes to exchange routines to support
163       accumulation in reverse mode. Adjoint of an
164       assignment is an addition.
165     o Changes to support compilation by TAMC (LR(1)
166       syntax) and by g77 under Linux ( 72 character
167       limit ).
168    
169    checkpoint15
170     Rewrote exchange routines to allow
171     o General tile <-> tile connectivity.
172     o TAMC reverse mode flag ( is this really needed? )
173     o Variable width overlap and exchange region widths.
174     o Hooks for sharing data via DMA, Arctic, Memory Channel,
175       shmput/shmget, VIA, SYSV shmem and every other cool
176       communication method.
177    
178    checkpoint14
179     Consistent isomorphism chages made. These allow dynamical core
180     to support both pressure and meters as a vertical coordinate.
181    
182    checkpoint13
183     Release which corrects global_max problem and a couple
184     of KGM time-averaging diagnostic errors. Also contains
185     a double-gyre experiment setup as well as the baseline
186     4 degree global template. The double gyre template is
187     organised to allow it to be applied automatically to
188     the baseline configuration.
189    
190    branch-point-rdot
191     A few tidy-ups have been made bt the real point of this
192     check-point (excuse the pun) is to allow a branch to be
193     made for the purposes of adding the rDot alterations.
194     I don't want to commit the rDot to the main-trunk until
195     we've actually tested it...
196    
197    checkpoint12
198     Tidy up and added generic genmake script (formerly
199     configure script).
200     Released to testers.
201    
202    checkpoint11
203     Re-arranged initialise() and introduced ini_vertical_grid()
204     and ini_masks_etc().
205    
206    checkpoint10
207     Introduced the configure script.
208     Separated out the diags package.
209     Added template for writing time-averages of tile/intermediate quantities.
210     Updated SIZE.h in exp2 and made the data big-endian.
211    
212    checkpoint9
213     MPI fix. Filename changes (meta/data). salbin*y stuff.
214     General tidy-up.
215     SST.bin SSS.bin added to verification/exp2
