3     Notes on tags used in MITgcmUV
4     ==============================
5 heimbach 1.47
6 adcroft 1.49 checkpoint40pre9
7     o added DST advection schemes
8     o fix MPI bug on SGI's
9     o modifications for non-linear free-surface
10     o fixed conditionals for fixed flow/passive tracer only mode
11     o added tension/strain form of stress tensor
12     o changes to commenting of arguments for TAF/TAMC
13     o added/updated many matlab scripts
14    
15 adcroft 1.48 checkpoint40pre8
16 heimbach 1.47 o new package rw/
17     Added method for dumping intermediate local arrays:
18     mdsio_writetile - same as mdsio_writefield except works from inside
19     bi,bj loop
20     mdsio_writelocal - same as mdsio_writetile except works for local
21     arrays
22     write_local_r? - higher-level wrapper for mdsio_writelocal
23     Controlled by diagFreq. Defaults to zero (ie. no dumps)
24     Example given at end of mom_vecinv.F that dumps some local arrays.
25     o replaced calc_mom_rhs.F by mom_fluxform.F/mom_vecinc.F to
26     control flux-form versus vector invariant code.
27     Switch is runtime flag vectorInvariantMomentum (defaults to false)
28     or genmake -DISABLE ...
29     o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
30     (additional storing is now needed for case vecinv;
31     currently nothing implemented to switch this storing off
32     in case fluxform is used since no CPP flag available).
33 heimbach 1.46
34     checkpoint40pre7
35     o bug fix in dynamics.F
36     calc_viscosity called before k=1,Nr loop.
37     o added some #ifdef's ALLOW_PASSIVE_TRACER
38     o cleaned initialisations in ctrl_map_ini
39     related to TAF
40 heimbach 1.45
41     checkpoint40pre6
42     o split dynamics into thermodynamics & dynamics
43     o corresponding split of calc_diffusivity into
44     calc_diffusivity, calc_viscosity
45     (kpp_calc_diff, kpp_calc_visc).
46     o Added diffkr, kapgm to control variables
47     o bug fix in gmredi_slope_limit for ldd97
48 adcroft 1.44
49     checkpoint40pre5
50     o proper initialization of Adams-Bashforth time stepping
51     + uses forward step for very first step of model (iter=0)
52     o re-generated *all* output since almost all output is modified by this
53     change (sorry but we've been putting this one off for about 2 years)
54     + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
55     *not* regenerated since they are already out of date and I don't
56     want to create the impression that they are suddenly working.
57     o removed KAP stuff for DEC's
58     o modified/added many .cvsignore files in */code and */input
59     o added new expt "solid-body.cs-32x32x1"
60     + this uses an alternative form of ini_curvilinear_grid.F which
61     is not necessarily any better than the current one...
62 heimbach 1.43
63     checkpoint40pre4
64     o added re-initialisations of utrans,vtrans,rtrans in
65     calc_common_factors which are crucial for TAF.
66     o extended iMin,jMin range for calc_common_factors,
67     calc_diffusivity
68     o added option ALLOW_PASSIVE_TRACER
69     o a few minor updates and fixes
70    
71 heimbach 1.42 checkpoint40pre3
72     o created calc_gtr1.F for gad package
73     o split the_main_loop and re-introduced forward_step
74     o some recomputations of nIter0 for TAMC
75    
76 heimbach 1.41 checkpoint40pre2
77     o Updated to latest branch of AJA, JMC
78     o Added gradient check package
79     o Added routines for passive tracer handling
80     o Added carbon sequestration sensitivity experiment
81    
82 heimbach 1.39 checkpoint39
83     o Modifications and fixes to support TAMC
84     (mainly missing or wrong directives)
85     o Corrected common blocks when fooling TAMC to produce adjoint I/O
86     in addummy_in_stepping
87     o Updated verification/vero/ (bug fixes in code/, correct pickups in input/)
88     o Enabled "sliced" (xz-,yz-) exchanges, needed for obcs.
89     o Included following packages:
90     cal: calendar
91     exf: external forcing
92     ecco: essential routines to control use of cal, exf
93     (NB: this is not the full ECCO environment)
94 heimbach 1.40 o disabled some packages by default in genmake
95 heimbach 1.39
96 heimbach 1.38 checkpoint38
97     o see notes_c37_adj.txt
98     o corrected wrong layer index in external_forcing_t
99     o replaced the_main_loop/forward_step by the_main_loop
100     o removed forceoutput from write_state
101     (replaced criteria for initial/final state)
102     o added runtime flag for pre-C35 pickups: usePickupBeforeC35
103 jmc 1.36
104 jmc 1.37 checkpoint37
105     o mdsio.F routine split and packaged in pkg/mdsio
106     (mdsio.F and mdsio_gl.F still exist in eesupp/src but are not
107     used unless genmake -disable=mdsio)
108     o allow a more precise surface-geopotential gradient for the atmosphere
109     taking into account the change in space of Alpha (=1/rho) at the surface.
110     o variable "etaN" (replace cg2d_x) is the surface R-anomaly [r unit]
111     (ocean: sea surface height [m] / atmos: surface pressure anomaly [Pa])
112     o Change units: Phi_Hydrostatic (=phiHyd), Phi_Surface(=cg2d_x) and
113     Phi_NonHydrostatic (=cg3d_x), all have now the dimension of a potential
114     [m2/s2] (pressure/rhoConst in the ocean ; Geo-Potential in the atmosphere).
115     o Time-Average diagnostics defined as a pseudo package "timeave".
116     o pickup files : old pickup (before c35) did not work with new code (c35
117     and after) unless activating 2 commented lines in initialise-varia.
118     o Non-Hydrostatic pickup file Pb fixed.
119     o bug with Rigid-lid version (since c35) fixed.
120    
121 jmc 1.36 checkpoint36
122 jmc 1.37 o implement Crank-Nickelson barotropic time-stepping
123 jmc 1.36 o recover Time-Average diagnostics
124     o fix Pb in checkpoint (PR#19)
125     o AIM become a standard package ; clean unused CPP_kees
126 jmc 1.35
127     checkpoint35
128     o subtantial rewrite of dynamics.f
129     o allows staggered time-stepping
130     o packaged obcs, aim (Atmospheric Physics), zonal_filt, shap_filt
131     o added bottom drag (linear + quadratic)
132 heimbach 1.33
133     checkpoint34
134     o Modified exchange routines for correct reverse simulation.
135     o Added verification output to comply with bug fix in impldiff.F
136     as of c33 (exp2, natl_box).
137     o Corrected store directives in dynamics.F
138     o Corrected array boundaries in impldiff.F
139     o Corrected array dimensions in gmredi.
140     Added temporary scalars to avoid storage by TAMC (gmredi, kpp).
141 heimbach 1.34 o Added routine GLOBAL_SUM_INT to global_sum.F
142 heimbach 1.33 o Added mdsio_gl.F for ECCO purposes.
143 adcroft 1.32
144     checkpoint33
145     o Fixed bug in lower BC in impldiff.F
146     o Fixed confusion about units of forcing arrays in FFIELDS.h
147     namely Fu,Fv,Qnet,Qsw,EmPmR:
148     - Removed verification/natl_box/code/external_fields_scale.F
149     (did not differ from that in model/src)
150     - Changed units of fu,fv,Qnet,Qsw,EmPmR back to proper units
151     (see FFIELDS.h for description)
152     - Scale fu,fv,Qnet,Qsw,EmPmR when used in external_forcing_surf.F,
153     kpp_calc.F and kpp_transport_t.F
154     - Removed model/src/external_fields_scale.F and calls to it
155     - verification/natl_box uses flux data with "atmospheric" sign so
156     a special version of external_fields_load.F is used to
157     change the data as it's read in. This way, the arrays
158     have the right units and signs at all times tha a user could
159     possibly use them.
160     o Corrected genmake to delete a temporary file during configuration
161 heimbach 1.31
162     checkpoint32
163     o Scaling of forcing fields moved from external_forcing.F to
164     external_fields_scale.F, called directly after loading fields.
165     o Surface relaxation terms added to surface tendency fields in
166     extra subroutine.
167     o impldiff.F changed to avoid storing by TAMC of huge intermediate
168     fields.
169     o Changes in GMRedi to comply with packaging structure.
170     o Modifications and bug fixes in KPP package.
171     o Verification experiment for KPP added (verification/nat_box/)
172 heimbach 1.30
173     checkpoint31
174     o Packages interface brought in line with defined standard
175     -> new routines packages_...F
176     -> changes in initialise_fixed.F, initialise_varia.F
177     -> enables initialisation interface for ECCO package
178     o Rescaling of external forcing fields immediately after read
179     (removed from external_forcing.F)
180     -> new: surface_fields_scale.F
181     -> affects ini_foorcing.F, external_fields_load.F
182     o Computation of surface tendencies before tendency updates.
183     -> new: external_forcing_surf.F
184     o Change of variable names useGMRedi, useKPP, useECCO
185     o Further changes in dynamics.F, impldiff.F for TAMC
186     o Tested for experiments 0, 2, 4.

205     o config_summary.F: replaced write_1D_... by write_0D_...
206     read_write.F: added subroutines write_0D_...
207     o routines calc_common_factors, calc_gs, calc_gt, calc_phi_hyd, find_rho:
208     included some initialisations required for TAMC.
209     o routine calc_isoslopes: modified sqrt computation to make it
210     differentiable for zero argument.
211     o routines dynamics, impldiff:
212     included store directives and tape key computations required for TAMC.

225     except the argument declarations. This was using up some memory.
226     o fixed macros like _ADT to work with both versions of Linux cpp
227     o cleaned up some unused and uninitialized variables
228     (helps when debugging with strict compile options)
229     o split up CPP_EEOPTIONS.h into options and macros
230     (macros are now in eesupp/inc/CPP_EEMACROS.h)
231     o patch for 2 processor JAM mode

238     o added a diagnostic of convective index
239     o moved call to calc_divg_hat() from dynamics() to solve_for_pressure()
240     (this is was partly for OBCs and NH but also in anticipation of
241     an explicit free-surface option)

281     checkpoint17
282     o Beginning to incorporating modularity
283     for supporting atmos. and ocean configs.
284     o Small changes for TAMC complinace

288     checkpoint16
289     o Minor changes to exchange routines to support
290     accumulation in reverse mode. Adjoint of an
291     assignment is an addition.
292     o Changes to support compilation by TAMC (LR(1)
293     syntax) and by g77 under Linux ( 72 character
294     limit ).
295 cnh 1.14
296     checkpoint15
297     Rewrote exchange routines to allow
298     o General tile <-> tile connectivity.
299     o TAMC reverse mode flag ( is this really needed? )
300     o Variable width overlap and exchange region widths.
301     o Hooks for sharing data via DMA, Arctic, Memory Channel,
302     shmput/shmget, VIA, SYSV shmem and every other cool
303     communication method.
304 cnh 1.13

310     Release which corrects global_max problem and a couple
311     of KGM time-averaging diagnostic errors. Also contains
312     a double-gyre experiment setup as well as the baseline
313     4 degree global template. The double gyre template is
314     organised to allow it to be applied automatically to
315     the baseline configuration.
316 adcroft 1.11
317     branch-point-rdot
318     A few tidy-ups have been made bt the real point of this
319     check-point (excuse the pun) is to allow a branch to be
320     made for the purposes of adding the rDot alterations.
321     I don't want to commit the rDot to the main-trunk until
322     we've actually tested it...
323 cnh 1.10
324     checkpoint12
