4      ==============================      ==============================
5    
6    checkpoint32
7     o Scaling of forcing fields moved from external_forcing.F to
8       external_fields_scale.F, called directly after loading fields.
9     o Surface relaxation terms added to surface tendency fields in
10       extra subroutine.
11     o impldiff.F changed to avoid storing by TAMC of huge intermediate
12       fields.
13     o Changes in GMRedi to comply with packaging structure.
14     o Modifications and bug fixes in KPP package.
15     o Verification experiment for KPP added (verification/nat_box/)
16    
17    checkpoint31
18     o Packages interface brought in line with defined standard
19       -> new routines packages_...F
20       -> changes in initialise_fixed.F, initialise_varia.F
21       -> enables initialisation interface for ECCO package
22     o Rescaling of external forcing fields immediately after read
23       (removed from external_forcing.F)
24       -> new: surface_fields_scale.F
25       -> affects ini_foorcing.F, external_fields_load.F
26     o Computation of surface tendencies before tendency updates.
27       -> new: external_forcing_surf.F
28     o Change of variable names useGMRedi, useKPP, useECCO
29     o Further changes in dynamics.F, impldiff.F for TAMC
30     o Tested for experiments 0, 2, 4.
31       - not yet tested for GMRedi.
32       - not yet tested for KPP.
33    
34    checkpoint30
35     o Updates for OBCs
36     o New experiment for test OBCs (internal_wave)
37     o New output.txt in verification/exp4/results/
38     o Updates for KPP: calculation of viscosity corrected, new variables
39       kpp_dumpFreq and kpp_taveFreq
40     o CPP'd calls to system routines for TARGET_CRAY_VECTOR (P.H.)
41       and entry for T90 in genmake
42    
43    checkpoint29
44     o packaged KPP and GM/Redi
45    
46    checkpoint28
47     o Corrected initialization of hFacMin for difference vertical coordinates
48     o Modified calculation of partial cell thickness to more robust algorithm
49     o config_summary.F: replaced write_1D_... by write_0D_...
50       read_write.F: added subroutines write_0D_...
51     o routines calc_common_factors, calc_gs, calc_gt, calc_phi_hyd, find_rho:
52       included some initialisations required for TAMC.
53     o routine calc_isoslopes: modified sqrt computation to make it
54       differentiable for zero argument.
55     o routines dynamics, impldiff:
56       included store directives and tape key computations required for TAMC.
57     o ALL TAMC related changes are between ifdef ALLOW_AUTODIFF_TAMC
58    
59    checkpoint27
60     o fixed calc_isoslopes() to so that cancellation of terms in tensor
61       formulation works properly with variable resolution.
62     o restructured the calling tree between the_model_main() and dynamics()
63     o split initialise() into initialise_fixed() and initialise_varia()
64     o introduced initialization file pSurfInitFile for free surface (cg2d_x)
65       in new routine ini_psurf()
66    
67    checkpoint26
68     o moved some #ifdef in optional routines to encompass everything
69       except the argument declarations. This was using up some memory.
70     o fixed macros like _ADT to work with both versions of Linux cpp
71     o cleaned up some unused and uninitialized variables
72       (helps when debugging with strict compile options)
73     o split up CPP_EEOPTIONS.h into options and macros
74       (macros are now in eesupp/inc/CPP_EEMACROS.h)
75     o patch for 2 processor JAM mode
76    
77    checkpoint25
78     o updates for OBCs and NH
79     o dramatically reduced memory usage
80     o added "JAM" routines for use on Artic network
81     o parameterization of convection by implicit vertical diffusion
82     o added a diagnostic of convective index
83     o moved call to calc_divg_hat() from dynamics() to solve_for_pressure()
84       (this is was partly for OBCs and NH but also in anticipation of
85        an explicit free-surface option)
86     o initial state input files for U and V
87    
88    checkpoint24
89     o Removed some spurious "REAL"s
90     o Updated KPP to latest version from JPL
91     o Added a COS(latitude) in horizontal viscosity
92    
93    checkpoint23
94     o Added del^4 diffusion for salt and temperature
95     o Multiple minor fixes (implicit none's, arguments to global_sum, etc.)
96    
97    checkpoint22
98     o Made many small changes: implicit none, format(i5), etc...
99     o Introduced KPP mixing scheme (compiles and runs but *not* tested)
100    
101    checkpoint21
102     o Introduced new I/O package that supports direct-access records (mdsio.F)
103     o Split-up mid-level I/O routines
104     o Updated input data for experiments 0,1,2,4 and 5
105     o Finally removed the genmake.* scripts (everyone seems happy with genmake)
106    
107    checkpoint20
108     o Tidied up open-boundaries some more
109     o Added non-hydrostatic code
110     o Fixed some input data
111     o Modified MPI start-up to work in "coupled" context.
112    
113    checkpoint19
114     o Tidied up directory structure for verification experiments.
115     o Added new code for open boundaries.
116     o Corrected advective terms near boundaries.
117     o Added CPP flag for "old UV" geometry and corrected spherical geometry.
118     o Implemented free-slip/no-slip BCs and del^4 dissipation.
119     o Split default parameters out of ini_parms.F into set_defaults.F.
120    
121    checkpoint18
122     o Further changes for optional code generation with
123       CPP - ugh!
124    
125    checkpoint17
126     o Beginning to incorporating modularity
127       for supporting atmos. and ocean configs.
128     o Small changes for TAMC complinace
129     o New ultra simple test case. Barotropic box
130       configuration "exp0".
131    
132    checkpoint16
133     o Minor changes to exchange routines to support
134       accumulation in reverse mode. Adjoint of an
135       assignment is an addition.
136     o Changes to support compilation by TAMC (LR(1)
137       syntax) and by g77 under Linux ( 72 character
138       limit ).
139    
140    checkpoint15
141     Rewrote exchange routines to allow
142     o General tile <-> tile connectivity.
143     o TAMC reverse mode flag ( is this really needed? )
144     o Variable width overlap and exchange region widths.
145     o Hooks for sharing data via DMA, Arctic, Memory Channel,
146       shmput/shmget, VIA, SYSV shmem and every other cool
147       communication method.
148    
149    checkpoint14
150     Consistent isomorphism chages made. These allow dynamical core
151     to support both pressure and meters as a vertical coordinate.
152    
153    checkpoint13
154     Release which corrects global_max problem and a couple
155     of KGM time-averaging diagnostic errors. Also contains
156     a double-gyre experiment setup as well as the baseline
157     4 degree global template. The double gyre template is
158     organised to allow it to be applied automatically to
159     the baseline configuration.
160    
161    branch-point-rdot
162     A few tidy-ups have been made bt the real point of this
163     check-point (excuse the pun) is to allow a branch to be
164     made for the purposes of adding the rDot alterations.
165     I don't want to commit the rDot to the main-trunk until
166     we've actually tested it...
167    
168    checkpoint12
169     Tidy up and added generic genmake script (formerly
170     configure script).
171     Released to testers.
172    
173    checkpoint11
174     Re-arranged initialise() and introduced ini_vertical_grid()
175     and ini_masks_etc().
176    
177    checkpoint10
178     Introduced the configure script.
179     Separated out the diags package.
180     Added template for writing time-averages of tile/intermediate quantities.
181     Updated SIZE.h in exp2 and made the data big-endian.
182    
183    checkpoint9
184     MPI fix. Filename changes (meta/data). salbin*y stuff.
185     General tidy-up.
186     SST.bin SSS.bin added to verification/exp2
187    
188    checkpoint8
189     Inludes time-dependant forcing and time-averaging.
190     Works at 4x4 and 2.8125x2.8125 global
191    
192    checkpoint7-4degree-ref
193     Branch from checkpoint7. Released for application to
194     global modeling and general modeling - process studies, regional
195     model etc..
196     Configured for verification/exp2 - 4 degree global, two process.
