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 mdsio_gl.F for ECCO purposes.
15    
16    checkpoint33
17     o Fixed bug in lower BC in impldiff.F
18     o Fixed confusion about units of forcing arrays in FFIELDS.h
19       namely Fu,Fv,Qnet,Qsw,EmPmR:
20       - Removed verification/natl_box/code/external_fields_scale.F
21         (did not differ from that in model/src)
22       - Changed units of fu,fv,Qnet,Qsw,EmPmR back to proper units
23         (see FFIELDS.h for description)
24       - Scale fu,fv,Qnet,Qsw,EmPmR when used in external_forcing_surf.F,
25         kpp_calc.F and kpp_transport_t.F
26       - Removed model/src/external_fields_scale.F and calls to it
27       - verification/natl_box uses flux data with "atmospheric" sign so
28         a special version of external_fields_load.F is used to
29         change the data as it's read in. This way, the arrays
30         have the right units and signs at all times tha a user could
31         possibly use them.
32     o Corrected genmake to delete a temporary file during configuration
33    
34    checkpoint32
35     o Scaling of forcing fields moved from external_forcing.F to
36       external_fields_scale.F, called directly after loading fields.
37     o Surface relaxation terms added to surface tendency fields in
38       extra subroutine.
39     o impldiff.F changed to avoid storing by TAMC of huge intermediate
40       fields.
41     o Changes in GMRedi to comply with packaging structure.
42     o Modifications and bug fixes in KPP package.
43     o Verification experiment for KPP added (verification/nat_box/)
44    
45    checkpoint31
46     o Packages interface brought in line with defined standard
47       -> new routines packages_...F
48       -> changes in initialise_fixed.F, initialise_varia.F
49       -> enables initialisation interface for ECCO package
50     o Rescaling of external forcing fields immediately after read
51       (removed from external_forcing.F)
52       -> new: surface_fields_scale.F
53       -> affects ini_foorcing.F, external_fields_load.F
54     o Computation of surface tendencies before tendency updates.
55       -> new: external_forcing_surf.F
56     o Change of variable names useGMRedi, useKPP, useECCO
57     o Further changes in dynamics.F, impldiff.F for TAMC
58     o Tested for experiments 0, 2, 4.
59       - not yet tested for GMRedi.
60       - not yet tested for KPP.
61    
62    checkpoint30
63     o Updates for OBCs
64     o New experiment for test OBCs (internal_wave)
65     o New output.txt in verification/exp4/results/
66     o Updates for KPP: calculation of viscosity corrected, new variables
67       kpp_dumpFreq and kpp_taveFreq
68     o CPP'd calls to system routines for TARGET_CRAY_VECTOR (P.H.)
69       and entry for T90 in genmake
70    
71    checkpoint29

73    
74    checkpoint28
75     o Corrected initialization of hFacMin for difference vertical coordinates
76     o Modified calculation of partial cell thickness to more robust algorithm
77     o config_summary.F: replaced write_1D_... by write_0D_...
78       read_write.F: added subroutines write_0D_...
79     o routines calc_common_factors, calc_gs, calc_gt, calc_phi_hyd, find_rho:
80       included some initialisations required for TAMC.
81     o routine calc_isoslopes: modified sqrt computation to make it
82       differentiable for zero argument.
83     o routines dynamics, impldiff:
84       included store directives and tape key computations required for TAMC.
85     o ALL TAMC related changes are between ifdef ALLOW_AUTODIFF_TAMC
86    
87    checkpoint27
88     o fixed calc_isoslopes() to so that cancellation of terms in tensor
89       formulation works properly with variable resolution.
90     o restructured the calling tree between the_model_main() and dynamics()
91     o split initialise() into initialise_fixed() and initialise_varia()
92     o introduced initialization file pSurfInitFile for free surface (cg2d_x)
93       in new routine ini_psurf()
94    
95    checkpoint26
96     o moved some #ifdef in optional routines to encompass everything
97       except the argument declarations. This was using up some memory.
98     o fixed macros like _ADT to work with both versions of Linux cpp
99     o cleaned up some unused and uninitialized variables
100       (helps when debugging with strict compile options)
101     o split up CPP_EEOPTIONS.h into options and macros
102       (macros are now in eesupp/inc/CPP_EEMACROS.h)
103     o patch for 2 processor JAM mode
104    
105    checkpoint25
106     o updates for OBCs and NH
107     o dramatically reduced memory usage
108     o added "JAM" routines for use on Artic network
109     o parameterization of convection by implicit vertical diffusion
110     o added a diagnostic of convective index
111     o moved call to calc_divg_hat() from dynamics() to solve_for_pressure()
112       (this is was partly for OBCs and NH but also in anticipation of
113        an explicit free-surface option)
114     o initial state input files for U and V
115    
116    checkpoint24
117     o Removed some spurious "REAL"s
118     o Updated KPP to latest version from JPL
119     o Added a COS(latitude) in horizontal viscosity
120    
121    checkpoint23

124    
125    checkpoint22
126     o Made many small changes: implicit none, format(i5), etc...
127     o Introduced KPP mixing scheme (compiles and runs but *not* tested)
128    
129    checkpoint21
130     o Introduced new I/O package that supports direct-access records (mdsio.F)
131     o Split-up mid-level I/O routines
132     o Updated input data for experiments 0,1,2,4 and 5
133     o Finally removed the genmake.* scripts (everyone seems happy with genmake)
134    
135    checkpoint20
136     o Tidied up open-boundaries some more
137     o Added non-hydrostatic code
138     o Fixed some input data
139     o Modified MPI start-up to work in "coupled" context.
140    
141    checkpoint19
142     o Tidied up directory structure for verification experiments.
143     o Added new code for open boundaries.
144     o Corrected advective terms near boundaries.
145     o Added CPP flag for "old UV" geometry and corrected spherical geometry.
146     o Implemented free-slip/no-slip BCs and del^4 dissipation.
147     o Split default parameters out of ini_parms.F into set_defaults.F.
148    
149    checkpoint18
150     o Further changes for optional code generation with
151       CPP - ugh!
152    
153    checkpoint17
154     o Beginning to incorporating modularity
155       for supporting atmos. and ocean configs.
156     o Small changes for TAMC complinace
157     o New ultra simple test case. Barotropic box
158       configuration "exp0".
159    
160    checkpoint16
161     o Minor changes to exchange routines to support
162       accumulation in reverse mode. Adjoint of an
163       assignment is an addition.
164     o Changes to support compilation by TAMC (LR(1)
165       syntax) and by g77 under Linux ( 72 character
166       limit ).
167    
168    checkpoint15
169     Rewrote exchange routines to allow
170     o General tile <-> tile connectivity.
171     o TAMC reverse mode flag ( is this really needed? )
172     o Variable width overlap and exchange region widths.
173     o Hooks for sharing data via DMA, Arctic, Memory Channel,
174       shmput/shmget, VIA, SYSV shmem and every other cool
175       communication method.
176    
177    checkpoint14
178     Consistent isomorphism chages made. These allow dynamical core
179     to support both pressure and meters as a vertical coordinate.
180    
181    checkpoint13
182     Release which corrects global_max problem and a couple
183     of KGM time-averaging diagnostic errors. Also contains
184     a double-gyre experiment setup as well as the baseline
185     4 degree global template. The double gyre template is
186     organised to allow it to be applied automatically to
187     the baseline configuration.
188    
189    branch-point-rdot
190     A few tidy-ups have been made bt the real point of this
191     check-point (excuse the pun) is to allow a branch to be
192     made for the purposes of adding the rDot alterations.
193     I don't want to commit the rDot to the main-trunk until
194     we've actually tested it...
195    
196  checkpoint12  checkpoint12
197   Tidy up and added generic genmake script (formerly   Tidy up and added generic genmake script (formerly
198   configure script).   configure script).
