5    
6    checkpoint31
7     o Packages interface brought in line with defined standard
8       -> new routines packages_...F
9       -> changes in initialise_fixed.F, initialise_varia.F
10       -> enables initialisation interface for ECCO package
11     o Rescaling of external forcing fields immediately after read
12       (removed from external_forcing.F)

14       -> affects ini_foorcing.F, external_fields_load.F
15     o Computation of surface tendencies before tendency updates.
16       -> new: external_forcing_surf.F
17     o Change of variable names useGMRedi, useKPP, useECCO
18     o Further changes in dynamics.F, impldiff.F for TAMC
19     o Tested for experiments 0, 2, 4.
20       - not yet tested for GMRedi.
21       - not yet tested for KPP.
22    
23    checkpoint30
24     o Updates for OBCs
25     o New experiment for test OBCs (internal_wave)
26     o New output.txt in verification/exp4/results/
27     o Updates for KPP: calculation of viscosity corrected, new variables
28       kpp_dumpFreq and kpp_taveFreq
29     o CPP'd calls to system routines for TARGET_CRAY_VECTOR (P.H.)
30       and entry for T90 in genmake
31    
32    checkpoint29
33     o packaged KPP and GM/Redi
34    
35    checkpoint28
36     o Corrected initialization of hFacMin for difference vertical coordinates
37     o Modified calculation of partial cell thickness to more robust algorithm
38     o config_summary.F: replaced write_1D_... by write_0D_...
39       read_write.F: added subroutines write_0D_...
40     o routines calc_common_factors, calc_gs, calc_gt, calc_phi_hyd, find_rho:
41       included some initialisations required for TAMC.
42     o routine calc_isoslopes: modified sqrt computation to make it
43       differentiable for zero argument.
44     o routines dynamics, impldiff:
45       included store directives and tape key computations required for TAMC.
46     o ALL TAMC related changes are between ifdef ALLOW_AUTODIFF_TAMC
47    
48    checkpoint27
49     o fixed calc_isoslopes() to so that cancellation of terms in tensor
50       formulation works properly with variable resolution.
51     o restructured the calling tree between the_model_main() and dynamics()
52     o split initialise() into initialise_fixed() and initialise_varia()
53     o introduced initialization file pSurfInitFile for free surface (cg2d_x)
54       in new routine ini_psurf()
55    
56    checkpoint26
57     o moved some #ifdef in optional routines to encompass everything
58       except the argument declarations. This was using up some memory.
59     o fixed macros like _ADT to work with both versions of Linux cpp
60     o cleaned up some unused and uninitialized variables
61       (helps when debugging with strict compile options)
62     o split up CPP_EEOPTIONS.h into options and macros
63       (macros are now in eesupp/inc/CPP_EEMACROS.h)
64     o patch for 2 processor JAM mode
65    
66    checkpoint25
67     o updates for OBCs and NH
68     o dramatically reduced memory usage
69     o added "JAM" routines for use on Artic network
70     o parameterization of convection by implicit vertical diffusion
71     o added a diagnostic of convective index
72     o moved call to calc_divg_hat() from dynamics() to solve_for_pressure()
73       (this is was partly for OBCs and NH but also in anticipation of
74        an explicit free-surface option)
75     o initial state input files for U and V
76    
77    checkpoint24
78     o Removed some spurious "REAL"s
79     o Updated KPP to latest version from JPL

81    
82    checkpoint23
83     o Added del^4 diffusion for salt and temperature
84     o Multiple minor fixes (implicit none's, arguments to global_sum, etc.)
85    
86    checkpoint22
87     o Made many small changes: implicit none, format(i5), etc...
88     o Introduced KPP mixing scheme (compiles and runs but *not* tested)
89    
90    checkpoint21
91     o Introduced new I/O package that supports direct-access records (mdsio.F)
92     o Split-up mid-level I/O routines
93     o Updated input data for experiments 0,1,2,4 and 5
94     o Finally removed the genmake.* scripts (everyone seems happy with genmake)
95    
96    checkpoint20
97     o Tidied up open-boundaries some more
98     o Added non-hydrostatic code
99     o Fixed some input data
100     o Modified MPI start-up to work in "coupled" context.
101    
102    checkpoint19
103     o Tidied up directory structure for verification experiments.
104     o Added new code for open boundaries.
105     o Corrected advective terms near boundaries.
106     o Added CPP flag for "old UV" geometry and corrected spherical geometry.
107     o Implemented free-slip/no-slip BCs and del^4 dissipation.
108     o Split default parameters out of ini_parms.F into set_defaults.F.
109    
110    checkpoint18
111     o Further changes for optional code generation with
112       CPP - ugh!
113    
114    checkpoint17
115     o Beginning to incorporating modularity
116       for supporting atmos. and ocean configs.
117     o Small changes for TAMC complinace
118     o New ultra simple test case. Barotropic box
119       configuration "exp0".
120    
121    checkpoint16
122     o Minor changes to exchange routines to support
123       accumulation in reverse mode. Adjoint of an
124       assignment is an addition.
125     o Changes to support compilation by TAMC (LR(1)
126       syntax) and by g77 under Linux ( 72 character
127       limit ).
128    
129    checkpoint15
130     Rewrote exchange routines to allow
131     o General tile <-> tile connectivity.
132     o TAMC reverse mode flag ( is this really needed? )
133     o Variable width overlap and exchange region widths.
134     o Hooks for sharing data via DMA, Arctic, Memory Channel,
135       shmput/shmget, VIA, SYSV shmem and every other cool
136       communication method.
137    
138    checkpoint14
139     Consistent isomorphism chages made. These allow dynamical core
140     to support both pressure and meters as a vertical coordinate.
141    
142    checkpoint13
143     Release which corrects global_max problem and a couple
144     of KGM time-averaging diagnostic errors. Also contains
145     a double-gyre experiment setup as well as the baseline
146     4 degree global template. The double gyre template is
147     organised to allow it to be applied automatically to
148     the baseline configuration.
149    
150    branch-point-rdot
151     A few tidy-ups have been made bt the real point of this
152     check-point (excuse the pun) is to allow a branch to be
153     made for the purposes of adding the rDot alterations.
154     I don't want to commit the rDot to the main-trunk until
155     we've actually tested it...
156    
157    checkpoint12
158     Tidy up and added generic genmake script (formerly
159     configure script).
160     Released to testers.
161    
162    checkpoint11
163     Re-arranged initialise() and introduced ini_vertical_grid()
164     and ini_masks_etc().
165    
166    checkpoint10
167     Introduced the configure script.
168     Separated out the diags package.
169     Added template for writing time-averages of tile/intermediate quantities.
170     Updated SIZE.h in exp2 and made the data big-endian.
171    
172    checkpoint9
173     MPI fix. Filename changes (meta/data). salbin*y stuff.
174     General tidy-up.
175     SST.bin SSS.bin added to verification/exp2
176    
177    checkpoint8
178     Inludes time-dependant forcing and time-averaging.
179     Works at 4x4 and 2.8125x2.8125 global
180    
181    checkpoint7-4degree-ref
182     Branch from checkpoint7. Released for application to
183     global modeling and general modeling - process studies, regional
184     model etc..
185     Configured for verification/exp2 - 4 degree global, two process.
186    
187    checkpoint7

190     configuration.
191     Includes climatological wind,
192     hydrography, bathymetry etc

194    
195    checkpoint6

197     merged checkpoint5 with CD and
198     spherical polar code.
199     Still some problems with GM Redi
200     abd full topography.

205     and reordered timestepping loop

213     for generation.
