3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    
6    checkpoint28
7     o Corrected initialization of hFacMin for difference vertical coordinates
8     o Modified calculation of partial cell thickness to more robust algorithm
9     o config_summary.F: replaced write_1D_... by write_0D_...
10       read_write.F: added subroutines write_0D_...
11     o routines calc_common_factors, calc_gs, calc_gt, calc_phi_hyd, find_rho:
12       included some initialisations required for TAMC.
13     o routine calc_isoslopes: modified sqrt computation to make it
14       differentiable for zero argument.
15     o routines dynamics, impldiff:
16       included store directives and tape key computations required for TAMC.
17     o ALL TAMC related changes are between ifdef ALLOW_AUTODIFF_TAMC
18    
19    checkpoint27
20     o fixed calc_isoslopes() to so that cancellation of terms in tensor
21       formulation works properly with variable resolution.
22     o restructured the calling tree between the_model_main() and dynamics()
23     o split initialise() into initialise_fixed() and initialise_varia()
24     o introduced initialization file pSurfInitFile for free surface (cg2d_x)
25       in new routine ini_psurf()
26    
27    checkpoint26
28     o moved some #ifdef in optional routines to encompass everything
29       except the argument declarations. This was using up some memory.
30     o fixed macros like _ADT to work with both versions of Linux cpp
31     o cleaned up some unused and uninitialized variables
32       (helps when debugging with strict compile options)
33     o split up CPP_EEOPTIONS.h into options and macros
34       (macros are now in eesupp/inc/CPP_EEMACROS.h)
35     o patch for 2 processor JAM mode
36    
37    checkpoint25
38     o updates for OBCs and NH
39     o dramatically reduced memory usage
40     o added "JAM" routines for use on Artic network
41     o parameterization of convection by implicit vertical diffusion
42     o added a diagnostic of convective index
43     o moved call to calc_divg_hat() from dynamics() to solve_for_pressure()
44       (this is was partly for OBCs and NH but also in anticipation of
45        an explicit free-surface option)
46     o initial state input files for U and V
47    
48    checkpoint24
49     o Removed some spurious "REAL"s
50     o Updated KPP to latest version from JPL
51     o Added a COS(latitude) in horizontal viscosity
52    
53    checkpoint23
54     o Added del^4 diffusion for salt and temperature
55     o Multiple minor fixes (implicit none's, arguments to global_sum, etc.)
56    
57    checkpoint22
58     o Made many small changes: implicit none, format(i5), etc...
59     o Introduced KPP mixing scheme (compiles and runs but *not* tested)
60    
61    checkpoint21
62     o Introduced new I/O package that supports direct-access records (mdsio.F)
63     o Split-up mid-level I/O routines
64     o Updated input data for experiments 0,1,2,4 and 5
65     o Finally removed the genmake.* scripts (everyone seems happy with genmake)
66    
67    checkpoint20
68     o Tidied up open-boundaries some more
69     o Added non-hydrostatic code
70     o Fixed some input data
71     o Modified MPI start-up to work in "coupled" context.
72    
73    checkpoint19
74     o Tidied up directory structure for verification experiments.
75     o Added new code for open boundaries.
76     o Corrected advective terms near boundaries.
77     o Added CPP flag for "old UV" geometry and corrected spherical geometry.
78     o Implemented free-slip/no-slip BCs and del^4 dissipation.
79     o Split default parameters out of ini_parms.F into set_defaults.F.
80    
81    checkpoint18
82     o Further changes for optional code generation with
83       CPP - ugh!
84    
85    checkpoint17
86     o Beginning to incorporating modularity
87       for supporting atmos. and ocean configs.
88     o Small changes for TAMC complinace
89     o New ultra simple test case. Barotropic box
90       configuration "exp0".
91    
92    checkpoint16
93     o Minor changes to exchange routines to support
94       accumulation in reverse mode. Adjoint of an
95       assignment is an addition.
96     o Changes to support compilation by TAMC (LR(1)
97       syntax) and by g77 under Linux ( 72 character
98       limit ).
99    
100    checkpoint15
101     Rewrote exchange routines to allow
102     o General tile <-> tile connectivity.
103     o TAMC reverse mode flag ( is this really needed? )
104     o Variable width overlap and exchange region widths.
105     o Hooks for sharing data via DMA, Arctic, Memory Channel,
106       shmput/shmget, VIA, SYSV shmem and every other cool
107       communication method.
108    
109    checkpoint14
110     Consistent isomorphism chages made. These allow dynamical core
111     to support both pressure and meters as a vertical coordinate.
112    
113    checkpoint13
114     Release which corrects global_max problem and a couple
115     of KGM time-averaging diagnostic errors. Also contains
116     a double-gyre experiment setup as well as the baseline
117     4 degree global template. The double gyre template is
118     organised to allow it to be applied automatically to
119     the baseline configuration.
