4      ==============================      ==============================
5    
6    o genmake2: add build & execute test for NetCDF code
7    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
8      old grid files, moved CPP_EEMACROS.h to pkg/exch2
9    o added useSingleCPUIO flag to monitor.F and mon_out.F
10    
11    checkpoint52f_post
12    o added exch2 cube routines to pkg/exch2
13    o modified hs94.cs-32x32x5 to use it
14    o added new grid files to hs94.cs-32x32x5
15    checkpoint52f_pre
16    
17    checkpoint52e_post
18    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
19      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
20    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
21      to work with implicit vertical advection and AB ;
22    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
23    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
24     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
25    checkpoint52e_pre
26    
27    o fix bug in impldiff when Nr=1 or Nr=2.
28    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
29    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
30    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
31      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
32    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
33    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
34    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
35    
36    checkpoint52d_post
37    o re-tiled many expts to allow comparison in multi-processor mode
38      - updated output accordingly
39      - changed hs94.128x64x5 to use intial T from file rather than use the
40        random number generator
41    o add infrastructure in model routines for fizhi and gridalt packages
42    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
43    o changes to permit hi-res, cubed-sphere, configuration
44      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
45      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
46      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
47        of surface winds for the cube
48      (A verification experiment, based on global_ocean.cs32x15, but with
49       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
50       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
51       complete with example surface forcing files and matlab scripts to look
52       at the output and compare it with that of global_ocean.cs32x15.)
53    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
54       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
55       to conform to the common rule.
56    o check-in the first version of the coupler + interfaces for multi-components
57       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
58       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
59       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
60       - ocean and atmos. share the same horizontal grid (no interpolation).
61       - exchanges between component and coupler is done in forward_step
62    o new verification experiment, cpl_aim+ocn:
63       coupled ocean - AIM atmosphere on cs32 grid.
64    
65    checkpoint52d_pre
66    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
67    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
68    
69    checkpoint52c_post
70    o Fixing OPTIONS files for use of exf:
71      - ALLOW_ECCO not needed
72      - ECCO_CPPOPTIONS.h should not be included from
73        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
74        as has been the case in the past
75      - All cal/exf related options are currently set in
76        single header file. Should remain so until we
77        agree on a consistent new policy.
78    o Removed all CPP options for cal package.
79      cal has no more CPP options.
80    o modified STOREs in GAD_ADVECTION
81    o corrected key comp. for passkey
82    
83    checkpoint52b_post
84    o new version: "thsice" of thermodynamic sea-ice pkg:
85     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
86     - modify fluxes but do not change theta directly;
87     - light cleaning of bulk_force pkg (still needed with thsice).
88     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
89       + output_thsice.txt to test thsice & bulk_force pkgs.
90    o put back grid & coriolis monitor output.
91    checkpoint52b_pre
92    
93    o call "do_the_model_io" at the beginning (=> dump initial state)
94    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
95    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
96      (need info on NUMBER_OF_PTRACERS)
97    o missing PTRACERS headers in some routines
98    o default tamc.h in pkg/autodiff supposed to crash
99      to ensure proper customization
100    
101    checkpoint52a_post
102    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
103      - moved surfaceTendencyTice from pkg/seaice to main code
104      - subroutine FREEZE_SURFACE now limits only surface temperature
105        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
106        => new output.txt for global_ocean.cs32x15 & global_with_exf
107      - keep the old version of FREEZE for backward compatibility;
108        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
109      - corresponding modifs for TAF directives
110    o added surface flux output variables to TIMEAVE_STATVARS
111    o time-averaged output for pkg/ptracers

117    o some bug fixes for #undef REAL4_IS_SLOW
118    
119    checkpoint52 = ecco_c52_e35
120    o after testing adjoints of checkpoint51u_post
121    
122    checkpoint51u_post
123    o this is the post-merge tag of the ecco-branch
124      (needs another clean checkout and re-testing)
125    o various natl_box_adjoint configs and results
126      but no input fields
127    o obcs adjoint not yet merged!
128    o adding ECCO global 1x1 and 2x2 degree configs
129    o updated/extended some store directives for seaice
130    o pkg/ecco now containes ecco-specific part of cost function
131    o top level routines the_main_loop, forward_step
132      supersede those in model/src/
133      previous input data.cost now in data.ecco
134      (new namelist ecco_cost_nml)
135    o in ctrl/ cleaned some cross-dependencies and updated CPP options
136    
137    checkpoint51t_post
138    o this is the pre-merge tag of the ecco-branch
139    
140    checkpoint51s_post
141    o cleanup: removed various obsolete #define-s
142    o pkg/grdchk
143      - renamed 'ph-grd 3' to 'grad-res'
144      - merged from ecco-branch
145        (remaining bug fixes for obcs gradient checks)
146      - additional high-precision output for testreport
147        (grep for 'precision_grdchk_result')
148    
149    checkpoint51r_post
150    o cleaned up or removed CPP_OPTIONS.h files
151    o updated results for some of the tests to reflect the new
152      optfiles (-ieee: -O0 instead of -O3)
153    
154    checkpoint51q_post
155    o cd_code:
156      - moved cd_scheme.F -> cd_code_scheme.F
157      - separate read_checkpoint from cd_code_ini_vars.F
158      - separated cd_code part from write_checkpoint
159      - updated AD_SOURCE, generated .flow
160      - added CD_CODE_VARS.h to the_main_loop
161      - Moving cd_code specific store dir.s to pkg/cd_code
162    o ctrl package totally restructured
163      - pack/unpack now optional and decoupled from
164        xx_/adxx_ I/O
165      - ctrl_pack/unpack cleaned
166        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
167      - confined inclusion of AD_CONFIG.h to where necessary.
168    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
169    
170    checkpoint51p_post
171    o create initial cd_code package
172      - WARNING: the initialization of fields within packages
173        is broken because INI_FIELDS (where READ_CHECKPOINT is
174        called) is called *before* PACKAGES_INIT_VARIABLES.
175        This seems to be backwards since
176        1) its important to initially zero the entire field including
177           the "halo" region
178        2) zeroing needs to be done *before* reading pickup info
179           and the pickup call might or might not happen in any
180           particular run
181      - this needs an overhaul for R2
182    o cleanup verification/*/code/GMREDI_OPTIONS.h
183    o cleanup testreport

195      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
196        change rho -> rho-rhoConst
197      - replace call find_rho to find_rhonum
198    o initialisation of rFlx extended to full array (required by TAF)
199      and shifted to thermodynamics
200    o removed PTRACERS.h in ptracers routine

220         global_ocean.cs32x15, and global_with_exf)
221    o added surface flux output variables to TIMEAVE_STATVARS
222    
223    checkpoint51n_pre
224    o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F
