11      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
12    o update AIM Equatorial Channel exp:
13      use standard aim_v23 pkg and change the SST fields to be more realistic.
14    o globalFile now works with exch2
15    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
16      mon_vort3.F to make exch2 friendly with >1 tile per cube face

21    o updated the tiling for global_ocean_pressure
22    checkpoint52i_pre
23    
24    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
25      the old pkg/aim).
26    
27    checkpoint52h_pre
28    o shortened offending lines in exch2_send_rx?.template
29    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator

31    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
32      old grid files, moved CPP_EEMACROS.h to pkg/exch2
33    o added useSingleCPUIO flag to monitor.F and mon_out.F
34    o added temporary hack for sea-ice dynamics on the cube:
35      metric terms are ignored and it is assumed that
36      there is no sea-ice on cube faces 1, 2, 4, and 5.
37    
38    checkpoint52f_post
39    o added exch2 cube routines to pkg/exch2
40    o modified hs94.cs-32x32x5 to use it
41    o added new grid files to hs94.cs-32x32x5
42    checkpoint52f_pre
43    
44    checkpoint52e_post
45    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
46      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
47    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
48      to work with implicit vertical advection and AB ;
49    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
50    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
51     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
52    checkpoint52e_pre
53    
54    o fix bug in impldiff when Nr=1 or Nr=2.
55    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
56    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
57    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
58      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
59    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
60    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
61    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
62    
63    checkpoint52d_post
64    o re-tiled many expts to allow comparison in multi-processor mode
65      - updated output accordingly
66      - changed hs94.128x64x5 to use intial T from file rather than use the
67        random number generator
68    o add infrastructure in model routines for fizhi and gridalt packages
69    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
70    o changes to permit hi-res, cubed-sphere, configuration
71      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
72      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
73      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
74        of surface winds for the cube
75      (A verification experiment, based on global_ocean.cs32x15, but with
76       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
77       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
78       complete with example surface forcing files and matlab scripts to look
79       at the output and compare it with that of global_ocean.cs32x15.)
80    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
81       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
82       to conform to the common rule.
83    o check-in the first version of the coupler + interfaces for multi-components
84       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
85       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
86       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
87       - ocean and atmos. share the same horizontal grid (no interpolation).
88       - exchanges between component and coupler is done in forward_step
89    o new verification experiment, cpl_aim+ocn:
90       coupled ocean - AIM atmosphere on cs32 grid.
91    
92    checkpoint52d_pre
93    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
94    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
95    
96    checkpoint52c_post
97    o Fixing OPTIONS files for use of exf:
98      - ALLOW_ECCO not needed
99      - ECCO_CPPOPTIONS.h should not be included from
100        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
101        as has been the case in the past
102      - All cal/exf related options are currently set in
103        single header file. Should remain so until we
104        agree on a consistent new policy.
105    o Removed all CPP options for cal package.
106      cal has no more CPP options.
107    o modified STOREs in GAD_ADVECTION
108    o corrected key comp. for passkey
109    
110    checkpoint52b_post
111    o new version: "thsice" of thermodynamic sea-ice pkg:
112     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
113     - modify fluxes but do not change theta directly;
114     - light cleaning of bulk_force pkg (still needed with thsice).
115     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
116       + output_thsice.txt to test thsice & bulk_force pkgs.
117    o put back grid & coriolis monitor output.
118    checkpoint52b_pre
119    
120    o call "do_the_model_io" at the beginning (=> dump initial state)
121    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
122    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
123      (need info on NUMBER_OF_PTRACERS)
124    o missing PTRACERS headers in some routines
125    o default tamc.h in pkg/autodiff supposed to crash
126      to ensure proper customization
127    
128    checkpoint52a_post
129    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
130      - moved surfaceTendencyTice from pkg/seaice to main code
131      - subroutine FREEZE_SURFACE now limits only surface temperature
132        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
133        => new output.txt for global_ocean.cs32x15 & global_with_exf
134      - keep the old version of FREEZE for backward compatibility;
135        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
136      - corresponding modifs for TAF directives
137    o added surface flux output variables to TIMEAVE_STATVARS
138    o time-averaged output for pkg/ptracers
139    o fix problem with ECCO-related divided adjoint

141      but no warning issued by TAF
142    
143    checkpoint52a_pre
144    o some bug fixes for #undef REAL4_IS_SLOW
145    
146    checkpoint52 = ecco_c52_e35
147    o after testing adjoints of checkpoint51u_post
148    
149    checkpoint51u_post
150    o this is the post-merge tag of the ecco-branch
151      (needs another clean checkout and re-testing)
152    o various natl_box_adjoint configs and results
153      but no input fields
154    o obcs adjoint not yet merged!
155    o adding ECCO global 1x1 and 2x2 degree configs
156    o updated/extended some store directives for seaice
157    o pkg/ecco now containes ecco-specific part of cost function
158    o top level routines the_main_loop, forward_step
159      supersede those in model/src/
160      previous input data.cost now in data.ecco
161      (new namelist ecco_cost_nml)
162    o in ctrl/ cleaned some cross-dependencies and updated CPP options
163    
164    checkpoint51t_post
165    o this is the pre-merge tag of the ecco-branch
166    
167    checkpoint51s_post
168    o cleanup: removed various obsolete #define-s
169    o pkg/grdchk
170      - renamed 'ph-grd 3' to 'grad-res'
171      - merged from ecco-branch
172        (remaining bug fixes for obcs gradient checks)
173      - additional high-precision output for testreport
174        (grep for 'precision_grdchk_result')
175    
176    checkpoint51r_post
177    o cleaned up or removed CPP_OPTIONS.h files
178    o updated results for some of the tests to reflect the new
179      optfiles (-ieee: -O0 instead of -O3)
180    
181    checkpoint51q_post
182    o cd_code:
183      - moved cd_scheme.F -> cd_code_scheme.F
184      - separate read_checkpoint from cd_code_ini_vars.F
185      - separated cd_code part from write_checkpoint
186      - updated AD_SOURCE, generated .flow
187      - added CD_CODE_VARS.h to the_main_loop
188      - Moving cd_code specific store dir.s to pkg/cd_code
189    o ctrl package totally restructured
190      - pack/unpack now optional and decoupled from
191        xx_/adxx_ I/O
192      - ctrl_pack/unpack cleaned
193        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
194      - confined inclusion of AD_CONFIG.h to where necessary.
195    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
196    
197    checkpoint51p_post
198    o create initial cd_code package
199      - WARNING: the initialization of fields within packages
200        is broken because INI_FIELDS (where READ_CHECKPOINT is
201        called) is called *before* PACKAGES_INIT_VARIABLES.
202        This seems to be backwards since
203        1) its important to initially zero the entire field including
204           the "halo" region
205        2) zeroing needs to be done *before* reading pickup info
206           and the pickup call might or might not happen in any
207           particular run
208      - this needs an overhaul for R2
209    o cleanup verification/*/code/GMREDI_OPTIONS.h
210    o cleanup testreport
211    
212    checkpoint51o_post
213    o bringing AD-related verif's up to date with genmake2

217      - (front_relax/ )
218    o (more) consistent directory structure for AD-related verif.'s
219    o cleaning ALLOW_GRADIENT_CHECK -> ALLOW_GRDCHK
220    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
221    o bug fix in find_alpha.F for MDJWF:
222      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
223        change rho -> rho-rhoConst
224      - replace call find_rho to find_rhonum
225    o initialisation of rFlx extended to full array (required by TAF)
226      and shifted to thermodynamics
227    o removed PTRACERS.h in ptracers routine
228    o added surfacetendencyPtr to S/R parameter list pracers_forcing
229    o Correcting initialisations for fVerU, fVerV.
230    o helping TAF to recognize dependency on kUp for
231      fVerU, fVerV
232    o Replacing delZ by delR in pkg/ctrl/
233    checkpoint51o_pre
234    
235    o undid all of cp51 pending some cleanups and discussion
236    o added the [#include "AD_CONFIG.h"] statement to all files that need
237       it for adjoint/tl #defines
238     o re-worked the build logic in genmake2 to support AD_CONFIG.h
239     o removed tools/genmake since it no longer works
240    
241    checkpoint51n_post
242    o modifications to make FREEZE flux visible to pkg/kpp
243      - moved surfaceTendencyTice from pkg/seaice to main code
244      - FREEZE & EXTERNAL_FORCING_SURF moved to FORWARD_STEP
245      - subroutine FREEZE now limits only surface temperature
246        (this means new output.txt for global_ocean.90x40x15,
247         global_ocean.cs32x15, and global_with_exf)
248    o added surface flux output variables to TIMEAVE_STATVARS
249    
250    checkpoint51n_pre
251    o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F
252    o added [#include "AD_CONFIG.h"] to all files that use the following
253      defines:
254      - ALLOW_ADJOINT_RUN
255      - ALLOW_TANGENTLINEAR_RUN
256      - ALLOW_ECCO_OPTIMIZATION
257    
258    checkpoint51m_post
259    o incorporating changes to get TAMC/TAF working in genmake2
260      - added new TAMC/TAF targets to the Makefile
261      - various cleanups related to package handling
262      - these changes should have no impact on the forward model
