6    checkpoint33
7     o Fixed bug in lower BC in impldiff.F
8     o Fixed confusion about units of forcing arrays in FFIELDS.h
9       namely Fu,Fv,Qnet,Qsw,EmPmR:
10       - Removed verification/natl_box/code/external_fields_scale.F
11         (did not differ from that in model/src)
12       - Changed units of fu,fv,Qnet,Qsw,EmPmR back to proper units
13         (see FFIELDS.h for description)
14       - Scale fu,fv,Qnet,Qsw,EmPmR when used in external_forcing_surf.F,
15         kpp_calc.F and kpp_transport_t.F
16       - Removed model/src/external_fields_scale.F and calls to it
17       - verification/natl_box uses flux data with "atmospheric" sign so
18         a special version of external_fields_load.F is used to
19         change the data as it's read in. This way, the arrays
20         have the right units and signs at all times tha a user could
21         possibly use them.
22     o Corrected genmake to delete a temporary file during configuration
23    
24    checkpoint32
25     o Scaling of forcing fields moved from external_forcing.F to
26       external_fields_scale.F, called directly after loading fields.
27     o Surface relaxation terms added to surface tendency fields in
28       extra subroutine.
29     o impldiff.F changed to avoid storing by TAMC of huge intermediate
30       fields.
31     o Changes in GMRedi to comply with packaging structure.
32     o Modifications and bug fixes in KPP package.
33     o Verification experiment for KPP added (verification/nat_box/)
34    
35    checkpoint31
36     o Packages interface brought in line with defined standard
37       -> new routines packages_...F
38       -> changes in initialise_fixed.F, initialise_varia.F
39       -> enables initialisation interface for ECCO package
40     o Rescaling of external forcing fields immediately after read
41       (removed from external_forcing.F)
42       -> new: surface_fields_scale.F
43       -> affects ini_foorcing.F, external_fields_load.F
44     o Computation of surface tendencies before tendency updates.
45       -> new: external_forcing_surf.F
46     o Change of variable names useGMRedi, useKPP, useECCO
47     o Further changes in dynamics.F, impldiff.F for TAMC
48     o Tested for experiments 0, 2, 4.
49       - not yet tested for GMRedi.
50       - not yet tested for KPP.
51    
52    checkpoint30
53     o Updates for OBCs
54     o New experiment for test OBCs (internal_wave)
55     o New output.txt in verification/exp4/results/
56     o Updates for KPP: calculation of viscosity corrected, new variables
57       kpp_dumpFreq and kpp_taveFreq
58     o CPP'd calls to system routines for TARGET_CRAY_VECTOR (P.H.)
59       and entry for T90 in genmake
60    
61    checkpoint29
62     o packaged KPP and GM/Redi
63    
64    checkpoint28
65     o Corrected initialization of hFacMin for difference vertical coordinates
66     o Modified calculation of partial cell thickness to more robust algorithm
67     o config_summary.F: replaced write_1D_... by write_0D_...
68       read_write.F: added subroutines write_0D_...
69     o routines calc_common_factors, calc_gs, calc_gt, calc_phi_hyd, find_rho:
70       included some initialisations required for TAMC.
71     o routine calc_isoslopes: modified sqrt computation to make it
72       differentiable for zero argument.
73     o routines dynamics, impldiff:
74       included store directives and tape key computations required for TAMC.
75     o ALL TAMC related changes are between ifdef ALLOW_AUTODIFF_TAMC
76    
77    checkpoint27
78     o fixed calc_isoslopes() to so that cancellation of terms in tensor
79       formulation works properly with variable resolution.
80     o restructured the calling tree between the_model_main() and dynamics()
81     o split initialise() into initialise_fixed() and initialise_varia()
82     o introduced initialization file pSurfInitFile for free surface (cg2d_x)
83       in new routine ini_psurf()
84    
85    checkpoint26
86     o moved some #ifdef in optional routines to encompass everything
87       except the argument declarations. This was using up some memory.
88     o fixed macros like _ADT to work with both versions of Linux cpp
89     o cleaned up some unused and uninitialized variables
90       (helps when debugging with strict compile options)
91     o split up CPP_EEOPTIONS.h into options and macros
92       (macros are now in eesupp/inc/CPP_EEMACROS.h)
93     o patch for 2 processor JAM mode
94    
95    checkpoint25
96     o updates for OBCs and NH
97     o dramatically reduced memory usage
98     o added "JAM" routines for use on Artic network
99     o parameterization of convection by implicit vertical diffusion
100     o added a diagnostic of convective index
101     o moved call to calc_divg_hat() from dynamics() to solve_for_pressure()
102       (this is was partly for OBCs and NH but also in anticipation of
103        an explicit free-surface option)
104     o initial state input files for U and V
105    
106    checkpoint24
107     o Removed some spurious "REAL"s
108     o Updated KPP to latest version from JPL
109     o Added a COS(latitude) in horizontal viscosity
110    
111    checkpoint23
112     o Added del^4 diffusion for salt and temperature
113     o Multiple minor fixes (implicit none's, arguments to global_sum, etc.)
114    
115    checkpoint22
116     o Made many small changes: implicit none, format(i5), etc...
117     o Introduced KPP mixing scheme (compiles and runs but *not* tested)
118    
119    checkpoint21
120     o Introduced new I/O package that supports direct-access records (mdsio.F)
121     o Split-up mid-level I/O routines
122     o Updated input data for experiments 0,1,2,4 and 5
123     o Finally removed the genmake.* scripts (everyone seems happy with genmake)
124    
125    checkpoint20
126     o Tidied up open-boundaries some more
127     o Added non-hydrostatic code
128     o Fixed some input data
129     o Modified MPI start-up to work in "coupled" context.
130    
131    checkpoint19
132     o Tidied up directory structure for verification experiments.
133     o Added new code for open boundaries.
134     o Corrected advective terms near boundaries.
135     o Added CPP flag for "old UV" geometry and corrected spherical geometry.
136     o Implemented free-slip/no-slip BCs and del^4 dissipation.
137     o Split default parameters out of ini_parms.F into set_defaults.F.
138    
139    checkpoint18
140     o Further changes for optional code generation with
141       CPP - ugh!
142    
143    checkpoint17
144     o Beginning to incorporating modularity
145       for supporting atmos. and ocean configs.
146     o Small changes for TAMC complinace
147     o New ultra simple test case. Barotropic box
148       configuration "exp0".
149    
150    checkpoint16
151     o Minor changes to exchange routines to support
152       accumulation in reverse mode. Adjoint of an
153       assignment is an addition.
154     o Changes to support compilation by TAMC (LR(1)
155       syntax) and by g77 under Linux ( 72 character
156       limit ).
157    
158    checkpoint15
159     Rewrote exchange routines to allow
160     o General tile <-> tile connectivity.
161     o TAMC reverse mode flag ( is this really needed? )
162     o Variable width overlap and exchange region widths.
163     o Hooks for sharing data via DMA, Arctic, Memory Channel,
164       shmput/shmget, VIA, SYSV shmem and every other cool
165       communication method.
166    
167    checkpoint14
168     Consistent isomorphism chages made. These allow dynamical core
169     to support both pressure and meters as a vertical coordinate.
170    
171    checkpoint13
172     Release which corrects global_max problem and a couple
173     of KGM time-averaging diagnostic errors. Also contains
174     a double-gyre experiment setup as well as the baseline
175     4 degree global template. The double gyre template is
176     organised to allow it to be applied automatically to
177     the baseline configuration.
178    
179    branch-point-rdot
180     A few tidy-ups have been made bt the real point of this
181     check-point (excuse the pun) is to allow a branch to be
182     made for the purposes of adding the rDot alterations.
183     I don't want to commit the rDot to the main-trunk until
184     we've actually tested it...
185    
186    checkpoint12
187     Tidy up and added generic genmake script (formerly
188     configure script).
189     Released to testers.
190    
191    checkpoint11
192     Re-arranged initialise() and introduced ini_vertical_grid()
193     and ini_masks_etc().
194    
195  checkpoint10  checkpoint10
196   Introduced the configure script.   Introduced the configure script.
197   Separated out the diags package.   Separated out the diags package.
