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

183     checkpoint31
184     o Packages interface brought in line with defined standard
185     -> new routines packages_...F
186     -> changes in initialise_fixed.F, initialise_varia.F
187     -> enables initialisation interface for ECCO package
188     o Rescaling of external forcing fields immediately after read
189     (removed from external_forcing.F)
190     -> new: surface_fields_scale.F
191     -> affects ini_foorcing.F, external_fields_load.F
192     o Computation of surface tendencies before tendency updates.
193     -> new: external_forcing_surf.F
194     o Change of variable names useGMRedi, useKPP, useECCO
195     o Further changes in dynamics.F, impldiff.F for TAMC
196     o Tested for experiments 0, 2, 4.

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

235     except the argument declarations. This was using up some memory.
236     o fixed macros like _ADT to work with both versions of Linux cpp
237     o cleaned up some unused and uninitialized variables
238     (helps when debugging with strict compile options)
239     o split up CPP_EEOPTIONS.h into options and macros
240     (macros are now in eesupp/inc/CPP_EEMACROS.h)
241     o patch for 2 processor JAM mode
242 adcroft 1.24

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

300     accumulation in reverse mode. Adjoint of an
301     assignment is an addition.
302     o Changes to support compilation by TAMC (LR(1)
303     syntax) and by g77 under Linux ( 72 character
304     limit ).
305 cnh 1.14
306     checkpoint15
307     Rewrote exchange routines to allow
308     o General tile <-> tile connectivity.
309     o TAMC reverse mode flag ( is this really needed? )
310     o Variable width overlap and exchange region widths.
311     o Hooks for sharing data via DMA, Arctic, Memory Channel,
312     shmput/shmget, VIA, SYSV shmem and every other cool
313     communication method.
314 cnh 1.13

321     of KGM time-averaging diagnostic errors. Also contains
322     a double-gyre experiment setup as well as the baseline
323     4 degree global template. The double gyre template is
324     organised to allow it to be applied automatically to
325     the baseline configuration.
326 adcroft 1.11
327     branch-point-rdot
328     A few tidy-ups have been made bt the real point of this
329     check-point (excuse the pun) is to allow a branch to be
330     made for the purposes of adding the rDot alterations.
331     I don't want to commit the rDot to the main-trunk until
332     we've actually tested it...
333 cnh 1.10
334     checkpoint12
