4      ==============================      ==============================
5    o aim.5l_cs: modify sea-ice fraction input file ; update output
6    
7    checkpoint52k_post
8    o removed top-level directory "diags"
9      - we migrated these functions to pkg/timeave a long time ago
10    o fixed bug introduced in pkg/monitor
11    o accuracy ctrlprec = 32 insuffient for gradient checks using
12      averaged fields (I/O via cost_averages)
13      -> use ctrl.h in active_file*.F to control I/O precision.
14    o paramter list of CALL ADTHE_MAIN_LOOP
15    o added initial do_the_model_io to ecco
16    o set all ...Freq to zero after cost_final
17      taveFreq, dumpFreq, pChkptFreq
18    o MAIN and ECCO differentiability restored
19    
20    checkpoint52j_post
21    o fix nchklev in tamc.h for global_ocean...
22    o Bringing flow and store directives up-to-date
23    o Really weird thing!
24      call do_the_model_io from the_main_loop with parameters
25      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
26      TAF places a faulty re-call of initialise_varia
27      after cost_final call which should not be there!
28    checkpoint52j_pre
29    
30    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
31      error messages
32    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
33    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
34      debug output
35    o modfied mdsio_writefield.F to handle non-global files under exch2
36    o update AIM Cubed-Sphere exp (aim.5l_cs):
37      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
38    o update AIM Equatorial Channel exp:
39      use standard aim_v23 pkg and change the SST fields to be more realistic.
40    o globalFile now works with exch2
41    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
42      mon_vort3.F to make exch2 friendly with >1 tile per cube face
43    o limit timeave output for hi-res integrations
44    
45    checkpoint52i_post
46    o removed CPP_EEOPTIONS.h from verification/*/code
47    o updated the tiling for global_ocean_pressure
48    checkpoint52i_pre
49    
50    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
51      the old pkg/aim).
52    
53    checkpoint52h_pre
54    o shortened offending lines in exch2_send_rx?.template
55    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
56    o genmake2: add build & execute test for NetCDF code
57    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
58      old grid files, moved CPP_EEMACROS.h to pkg/exch2
59    o added useSingleCPUIO flag to monitor.F and mon_out.F
60    o added temporary hack for sea-ice dynamics on the cube:
61      metric terms are ignored and it is assumed that
62      there is no sea-ice on cube faces 1, 2, 4, and 5.
63    
64    checkpoint52f_post
65    o added exch2 cube routines to pkg/exch2
66    o modified hs94.cs-32x32x5 to use it
67    o added new grid files to hs94.cs-32x32x5
68    checkpoint52f_pre
69    
70    checkpoint52e_post
71    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
72      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
73    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
74      to work with implicit vertical advection and AB ;
75    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
76    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
77     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
78    checkpoint52e_pre
79    
80    o fix bug in impldiff when Nr=1 or Nr=2.
81    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
82    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
83    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
84      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
85    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
86    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
87    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
88    
89    checkpoint52d_post
90    o re-tiled many expts to allow comparison in multi-processor mode
91      - updated output accordingly
92      - changed hs94.128x64x5 to use intial T from file rather than use the
93        random number generator
94    o add infrastructure in model routines for fizhi and gridalt packages
95    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
96    o changes to permit hi-res, cubed-sphere, configuration
97      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
98      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
99      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
100        of surface winds for the cube
101      (A verification experiment, based on global_ocean.cs32x15, but with
102       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
103       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
104       complete with example surface forcing files and matlab scripts to look
105       at the output and compare it with that of global_ocean.cs32x15.)
106    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
107       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
108       to conform to the common rule.
109    o check-in the first version of the coupler + interfaces for multi-components
110       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
111       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
112       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
113       - ocean and atmos. share the same horizontal grid (no interpolation).
114       - exchanges between component and coupler is done in forward_step
115    o new verification experiment, cpl_aim+ocn:
116       coupled ocean - AIM atmosphere on cs32 grid.
117    
118    checkpoint52d_pre
119    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
120    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
121    
122    checkpoint52c_post
123    o Fixing OPTIONS files for use of exf:
124      - ALLOW_ECCO not needed
125      - ECCO_CPPOPTIONS.h should not be included from
126        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
127        as has been the case in the past
128      - All cal/exf related options are currently set in
129        single header file. Should remain so until we
130        agree on a consistent new policy.
131    o Removed all CPP options for cal package.
132      cal has no more CPP options.
133    o modified STOREs in GAD_ADVECTION
134    o corrected key comp. for passkey
135    
136    checkpoint52b_post
137    o new version: "thsice" of thermodynamic sea-ice pkg:
138     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
139     - modify fluxes but do not change theta directly;
140     - light cleaning of bulk_force pkg (still needed with thsice).
141     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
142       + output_thsice.txt to test thsice & bulk_force pkgs.
143    o put back grid & coriolis monitor output.
144    checkpoint52b_pre
145    
146    o call "do_the_model_io" at the beginning (=> dump initial state)
147    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
148    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
149      (need info on NUMBER_OF_PTRACERS)
150    o missing PTRACERS headers in some routines
151    o default tamc.h in pkg/autodiff supposed to crash
152      to ensure proper customization
153    
154    checkpoint52a_post
155    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
156      - moved surfaceTendencyTice from pkg/seaice to main code
157      - subroutine FREEZE_SURFACE now limits only surface temperature
158        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
159        => new output.txt for global_ocean.cs32x15 & global_with_exf
160      - keep the old version of FREEZE for backward compatibility;
161        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
162      - corresponding modifs for TAF directives
163    o added surface flux output variables to TIMEAVE_STATVARS
164    o time-averaged output for pkg/ptracers
165    o fix problem with ECCO-related divided adjoint
166      snapshot file was missing some ad-variables,
167      but no warning issued by TAF
168    
169    checkpoint52a_pre
170    o some bug fixes for #undef REAL4_IS_SLOW
171    
172    checkpoint52 = ecco_c52_e35
173    o after testing adjoints of checkpoint51u_post
174    
175    checkpoint51u_post
176    o this is the post-merge tag of the ecco-branch
177      (needs another clean checkout and re-testing)
178    o various natl_box_adjoint configs and results
179      but no input fields
180    o obcs adjoint not yet merged!
181    o adding ECCO global 1x1 and 2x2 degree configs
182    o updated/extended some store directives for seaice
183    o pkg/ecco now containes ecco-specific part of cost function
184    o top level routines the_main_loop, forward_step
185      supersede those in model/src/
186      previous input data.cost now in data.ecco
187      (new namelist ecco_cost_nml)
188    o in ctrl/ cleaned some cross-dependencies and updated CPP options
189    
190    checkpoint51t_post
191    o this is the pre-merge tag of the ecco-branch
192    
193    checkpoint51s_post
194    o cleanup: removed various obsolete #define-s
195    o pkg/grdchk
196      - renamed 'ph-grd 3' to 'grad-res'
197      - merged from ecco-branch
198        (remaining bug fixes for obcs gradient checks)
199      - additional high-precision output for testreport
200        (grep for 'precision_grdchk_result')
201    
202    checkpoint51r_post
203    o cleaned up or removed CPP_OPTIONS.h files
204    o updated results for some of the tests to reflect the new
205      optfiles (-ieee: -O0 instead of -O3)
206
