3     Notes on tags used in MITgcmUV
4     ==============================
5 adcroft 1.51
6     checkpoint41
7     o re-formatted/added comments in prologues of key subroutines
8     to work with protex
9 heimbach 1.47
10 adcroft 1.50 checkpoint40
11     o moved calc_gs, calc_gt and calc_tr1 back to model/src
12     o added FLT (floats) package from Arne along with demo. experiment
13     o re-arranged Adams-Bashforth scheme for tracers to allow easier
14     implementation of forward-in-time forcing terms
15     o more mods for non-linear free-surface including new variable
16     o modified multi-dim method to work on cube
17     o bug fix in KPP (from DM)
18    
19 adcroft 1.49 checkpoint40pre9
20     o added DST advection schemes
21     o fix MPI bug on SGI's
22     o modifications for non-linear free-surface
23     o fixed conditionals for fixed flow/passive tracer only mode
24     o added tension/strain form of stress tensor
25     o changes to commenting of arguments for TAF/TAMC
26     o added/updated many matlab scripts
27 adcroft 1.50 o added multi-dimensional advection method for tracers
28 adcroft 1.49
29 adcroft 1.48 checkpoint40pre8
30 heimbach 1.47 o new package rw/
31     Added method for dumping intermediate local arrays:
32     mdsio_writetile - same as mdsio_writefield except works from inside
33     bi,bj loop
34     mdsio_writelocal - same as mdsio_writetile except works for local
35     arrays
36     write_local_r? - higher-level wrapper for mdsio_writelocal
37     Controlled by diagFreq. Defaults to zero (ie. no dumps)
38     Example given at end of mom_vecinv.F that dumps some local arrays.
39     o replaced calc_mom_rhs.F by mom_fluxform.F/mom_vecinc.F to
40     control flux-form versus vector invariant code.
41     Switch is runtime flag vectorInvariantMomentum (defaults to false)
42     or genmake -DISABLE ...
43     o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
44     (additional storing is now needed for case vecinv;
45     currently nothing implemented to switch this storing off
46     in case fluxform is used since no CPP flag available).
47 heimbach 1.46
48     checkpoint40pre7
49     o bug fix in dynamics.F
50     calc_viscosity called before k=1,Nr loop.
51     o added some #ifdef's ALLOW_PASSIVE_TRACER
52     o cleaned initialisations in ctrl_map_ini
53     related to TAF
54 heimbach 1.45
55     checkpoint40pre6
56     o split dynamics into thermodynamics & dynamics
57     o corresponding split of calc_diffusivity into
58     calc_diffusivity, calc_viscosity
59     (kpp_calc_diff, kpp_calc_visc).
60     o Added diffkr, kapgm to control variables
61     o bug fix in gmredi_slope_limit for ldd97
62 adcroft 1.44
63     checkpoint40pre5
64     o proper initialization of Adams-Bashforth time stepping
65     + uses forward step for very first step of model (iter=0)
66     o re-generated *all* output since almost all output is modified by this
67     change (sorry but we've been putting this one off for about 2 years)
68     + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
69     *not* regenerated since they are already out of date and I don't
70     want to create the impression that they are suddenly working.
71     o removed KAP stuff for DEC's
72     o modified/added many .cvsignore files in */code and */input
73     o added new expt "solid-body.cs-32x32x1"
74     + this uses an alternative form of ini_curvilinear_grid.F which
75     is not necessarily any better than the current one...
76 heimbach 1.43
77     checkpoint40pre4
78     o added re-initialisations of utrans,vtrans,rtrans in
79     calc_common_factors which are crucial for TAF.
80     o extended iMin,jMin range for calc_common_factors,
81     calc_diffusivity
82     o added option ALLOW_PASSIVE_TRACER
83     o a few minor updates and fixes
84    
85 heimbach 1.42 checkpoint40pre3
86     o created calc_gtr1.F for gad package
87     o split the_main_loop and re-introduced forward_step
88     o some recomputations of nIter0 for TAMC
89    
90 heimbach 1.41 checkpoint40pre2
91     o Updated to latest branch of AJA, JMC
92     o Added gradient check package
93     o Added routines for passive tracer handling
94     o Added carbon sequestration sensitivity experiment
95    
96 heimbach 1.39 checkpoint39
97     o Modifications and fixes to support TAMC
98     (mainly missing or wrong directives)
99     o Corrected common blocks when fooling TAMC to produce adjoint I/O
100     in addummy_in_stepping
101     o Updated verification/vero/ (bug fixes in code/, correct pickups in input/)
102     o Enabled "sliced" (xz-,yz-) exchanges, needed for obcs.
103     o Included following packages:
104     cal: calendar
105     exf: external forcing
106     ecco: essential routines to control use of cal, exf
107     (NB: this is not the full ECCO environment)
108 heimbach 1.40 o disabled some packages by default in genmake
109 heimbach 1.39
110 heimbach 1.38 checkpoint38
111     o see notes_c37_adj.txt
112     o corrected wrong layer index in external_forcing_t
113     o replaced the_main_loop/forward_step by the_main_loop
114     o removed forceoutput from write_state
115     (replaced criteria for initial/final state)
116     o added runtime flag for pre-C35 pickups: usePickupBeforeC35
117 jmc 1.36
118 jmc 1.37 checkpoint37
119     o mdsio.F routine split and packaged in pkg/mdsio
120     (mdsio.F and mdsio_gl.F still exist in eesupp/src but are not
121     used unless genmake -disable=mdsio)
122     o allow a more precise surface-geopotential gradient for the atmosphere
123     taking into account the change in space of Alpha (=1/rho) at the surface.
124     o variable "etaN" (replace cg2d_x) is the surface R-anomaly [r unit]
125     (ocean: sea surface height [m] / atmos: surface pressure anomaly [Pa])
126     o Change units: Phi_Hydrostatic (=phiHyd), Phi_Surface(=cg2d_x) and
127     Phi_NonHydrostatic (=cg3d_x), all have now the dimension of a potential
128     [m2/s2] (pressure/rhoConst in the ocean ; Geo-Potential in the atmosphere).
129     o Time-Average diagnostics defined as a pseudo package "timeave".
130     o pickup files : old pickup (before c35) did not work with new code (c35
131     and after) unless activating 2 commented lines in initialise-varia.
132     o Non-Hydrostatic pickup file Pb fixed.
133     o bug with Rigid-lid version (since c35) fixed.
134    
135 jmc 1.36 checkpoint36
136 jmc 1.37 o implement Crank-Nickelson barotropic time-stepping
137 jmc 1.36 o recover Time-Average diagnostics
138     o fix Pb in checkpoint (PR#19)
139     o AIM become a standard package ; clean unused CPP_kees
140 jmc 1.35
141     checkpoint35
142     o subtantial rewrite of dynamics.f
143     o allows staggered time-stepping
144     o packaged obcs, aim (Atmospheric Physics), zonal_filt, shap_filt
145     o added bottom drag (linear + quadratic)
146 heimbach 1.33
147     checkpoint34
148     o Modified exchange routines for correct reverse simulation.
149     o Added verification output to comply with bug fix in impldiff.F
150     as of c33 (exp2, natl_box).
151     o Corrected store directives in dynamics.F
152     o Corrected array boundaries in impldiff.F
153     o Corrected array dimensions in gmredi.
154     Added temporary scalars to avoid storage by TAMC (gmredi, kpp).
155 heimbach 1.34 o Added routine GLOBAL_SUM_INT to global_sum.F
156 heimbach 1.33 o Added mdsio_gl.F for ECCO purposes.
157 adcroft 1.32
158     checkpoint33
159     o Fixed bug in lower BC in impldiff.F
160     o Fixed confusion about units of forcing arrays in FFIELDS.h
161     namely Fu,Fv,Qnet,Qsw,EmPmR:
162     - Removed verification/natl_box/code/external_fields_scale.F
163     (did not differ from that in model/src)
164     - Changed units of fu,fv,Qnet,Qsw,EmPmR back to proper units
165     (see FFIELDS.h for description)
166     - Scale fu,fv,Qnet,Qsw,EmPmR when used in external_forcing_surf.F,
167     kpp_calc.F and kpp_transport_t.F
168     - Removed model/src/external_fields_scale.F and calls to it
169     - verification/natl_box uses flux data with "atmospheric" sign so
170     a special version of external_fields_load.F is used to
171     change the data as it's read in. This way, the arrays
172     have the right units and signs at all times tha a user could
173     possibly use them.
174     o Corrected genmake to delete a temporary file during configuration
175 heimbach 1.31
176     checkpoint32
177     o Scaling of forcing fields moved from external_forcing.F to
178     external_fields_scale.F, called directly after loading fields.
179     o Surface relaxation terms added to surface tendency fields in
180     extra subroutine.
181     o impldiff.F changed to avoid storing by TAMC of huge intermediate
182     fields.
183     o Changes in GMRedi to comply with packaging structure.
184     o Modifications and bug fixes in KPP package.
185     o Verification experiment for KPP added (verification/nat_box/)

189     -> new routines packages_...F
190     -> changes in initialise_fixed.F, initialise_varia.F
191     -> enables initialisation interface for ECCO package
192     o Rescaling of external forcing fields immediately after read
193     (removed from external_forcing.F)
194     -> new: surface_fields_scale.F
195     -> affects ini_foorcing.F, external_fields_load.F
196     o Computation of surface tendencies before tendency updates.
197     -> new: external_forcing_surf.F
198     o Change of variable names useGMRedi, useKPP, useECCO
199     o Further changes in dynamics.F, impldiff.F for TAMC

219     o config_summary.F: replaced write_1D_... by write_0D_...
220     read_write.F: added subroutines write_0D_...
221     o routines calc_common_factors, calc_gs, calc_gt, calc_phi_hyd, find_rho:
222     included some initialisations required for TAMC.
223     o routine calc_isoslopes: modified sqrt computation to make it
224     differentiable for zero argument.
225     o routines dynamics, impldiff:
226     included store directives and tape key computations required for TAMC.
227     o ALL TAMC related changes are between ifdef ALLOW_AUTODIFF_TAMC
228 adcroft 1.26
229     checkpoint27
230     o fixed calc_isoslopes() to so that cancellation of terms in tensor
231     formulation works properly with variable resolution.

239     except the argument declarations. This was using up some memory.
240     o fixed macros like _ADT to work with both versions of Linux cpp
241     o cleaned up some unused and uninitialized variables
242     (helps when debugging with strict compile options)
243     o split up CPP_EEOPTIONS.h into options and macros
244     (macros are now in eesupp/inc/CPP_EEMACROS.h)
245     o patch for 2 processor JAM mode

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

304     accumulation in reverse mode. Adjoint of an
305     assignment is an addition.
306     o Changes to support compilation by TAMC (LR(1)
307     syntax) and by g77 under Linux ( 72 character
308     limit ).
309 cnh 1.14
310     checkpoint15
311     Rewrote exchange routines to allow
312     o General tile <-> tile connectivity.
313     o TAMC reverse mode flag ( is this really needed? )
314     o Variable width overlap and exchange region widths.
315     o Hooks for sharing data via DMA, Arctic, Memory Channel,

325     of KGM time-averaging diagnostic errors. Also contains
326     a double-gyre experiment setup as well as the baseline
327     4 degree global template. The double gyre template is
328     organised to allow it to be applied automatically to
329     the baseline configuration.
330 adcroft 1.11
331     branch-point-rdot
332     A few tidy-ups have been made bt the real point of this
333     check-point (excuse the pun) is to allow a branch to be
334     made for the purposes of adding the rDot alterations.
335     I don't want to commit the rDot to the main-trunk until
336     we've actually tested it...
337 cnh 1.10
