4      ==============================      ==============================
5    
6    checkpoint52h_pre
7    o shortened offending lines in exch2_send_rx?.template
8    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
9    o genmake2: add build & execute test for NetCDF code
10    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
11      old grid files, moved CPP_EEMACROS.h to pkg/exch2
12    o added useSingleCPUIO flag to monitor.F and mon_out.F
13    o added temporary hack for sea-ice dynamics on the cube:
14      metric terms are ignored and it is assumed that
15      there is no sea-ice on cube faces 1, 2, 4, and 5.
16    
17    checkpoint52f_post
18    o added exch2 cube routines to pkg/exch2
19    o modified hs94.cs-32x32x5 to use it
20    o added new grid files to hs94.cs-32x32x5
21    checkpoint52f_pre
22    
23    checkpoint52e_post
24    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
25      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
26    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
27      to work with implicit vertical advection and AB ;
28    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
29    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
30     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
31    checkpoint52e_pre
32    
33    o fix bug in impldiff when Nr=1 or Nr=2.
34    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
35    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
36    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
37      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
38    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
39    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
40    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
41    
42    checkpoint52d_post
43    o re-tiled many expts to allow comparison in multi-processor mode
44      - updated output accordingly
45      - changed hs94.128x64x5 to use intial T from file rather than use the
46        random number generator
47    o add infrastructure in model routines for fizhi and gridalt packages
48    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
49    o changes to permit hi-res, cubed-sphere, configuration
50      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
51      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
52      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
53        of surface winds for the cube
54      (A verification experiment, based on global_ocean.cs32x15, but with
55       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
56       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
57       complete with example surface forcing files and matlab scripts to look
58       at the output and compare it with that of global_ocean.cs32x15.)
59    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
60       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
61       to conform to the common rule.
62    o check-in the first version of the coupler + interfaces for multi-components
63       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
64       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
65       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
66       - ocean and atmos. share the same horizontal grid (no interpolation).
67       - exchanges between component and coupler is done in forward_step
68    o new verification experiment, cpl_aim+ocn:
69       coupled ocean - AIM atmosphere on cs32 grid.
70    
71    checkpoint52d_pre
72    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
73    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
74    
75    checkpoint52c_post
76    o Fixing OPTIONS files for use of exf:
77      - ALLOW_ECCO not needed
78      - ECCO_CPPOPTIONS.h should not be included from
79        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
80        as has been the case in the past
81      - All cal/exf related options are currently set in
82        single header file. Should remain so until we
83        agree on a consistent new policy.
84    o Removed all CPP options for cal package.
85      cal has no more CPP options.
86    o modified STOREs in GAD_ADVECTION
87    o corrected key comp. for passkey
88    
89    checkpoint52b_post
90    o new version: "thsice" of thermodynamic sea-ice pkg:
91     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
92     - modify fluxes but do not change theta directly;
93     - light cleaning of bulk_force pkg (still needed with thsice).
94     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
95       + output_thsice.txt to test thsice & bulk_force pkgs.
96    o put back grid & coriolis monitor output.
97    checkpoint52b_pre
98    
99    o call "do_the_model_io" at the beginning (=> dump initial state)
100    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
101    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
102      (need info on NUMBER_OF_PTRACERS)
103    o missing PTRACERS headers in some routines
104    o default tamc.h in pkg/autodiff supposed to crash
105      to ensure proper customization
106    
107    checkpoint52a_post
108    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
109      - moved surfaceTendencyTice from pkg/seaice to main code
110      - subroutine FREEZE_SURFACE now limits only surface temperature
111        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
112        => new output.txt for global_ocean.cs32x15 & global_with_exf
113      - keep the old version of FREEZE for backward compatibility;
114        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
115      - corresponding modifs for TAF directives
116    o added surface flux output variables to TIMEAVE_STATVARS
117    o time-averaged output for pkg/ptracers

126    o after testing adjoints of checkpoint51u_post
127    
128    checkpoint51u_post
129    o this is the post-merge tag of the ecco-branch
130      (needs another clean checkout and re-testing)
131    o various natl_box_adjoint configs and results
132      but no input fields
133    o obcs adjoint not yet merged!
134    o adding ECCO global 1x1 and 2x2 degree configs
135    o updated/extended some store directives for seaice
136    o pkg/ecco now containes ecco-specific part of cost function
137    o top level routines the_main_loop, forward_step
138      supersede those in model/src/
139      previous input data.cost now in data.ecco
140      (new namelist ecco_cost_nml)
141    o in ctrl/ cleaned some cross-dependencies and updated CPP options
142    
143    checkpoint51t_post
144    o this is the pre-merge tag of the ecco-branch
145    
146    checkpoint51s_post
147    o cleanup: removed various obsolete #define-s
148    o pkg/grdchk
149      - renamed 'ph-grd 3' to 'grad-res'
150      - merged from ecco-branch
151        (remaining bug fixes for obcs gradient checks)
152      - additional high-precision output for testreport
153        (grep for 'precision_grdchk_result')
154    
155    checkpoint51r_post
156    o cleaned up or removed CPP_OPTIONS.h files
157    o updated results for some of the tests to reflect the new
158      optfiles (-ieee: -O0 instead of -O3)
159    
160    checkpoint51q_post
161    o cd_code:
162      - moved cd_scheme.F -> cd_code_scheme.F
163      - separate read_checkpoint from cd_code_ini_vars.F
164      - separated cd_code part from write_checkpoint
165      - updated AD_SOURCE, generated .flow

168    o ctrl package totally restructured
169      - pack/unpack now optional and decoupled from
170        xx_/adxx_ I/O

173      - confined inclusion of AD_CONFIG.h to where necessary.
174    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
175    
176    checkpoint51p_post
177    o create initial cd_code package
178      - WARNING: the initialization of fields within packages
179        is broken because INI_FIELDS (where READ_CHECKPOINT is
180        called) is called *before* PACKAGES_INIT_VARIABLES.
181        This seems to be backwards since
182        1) its important to initially zero the entire field including
183           the "halo" region
184        2) zeroing needs to be done *before* reading pickup info
185           and the pickup call might or might not happen in any
186           particular run
187      - this needs an overhaul for R2
188    o cleanup verification/*/code/GMREDI_OPTIONS.h
189    o cleanup testreport

201      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
202        change rho -> rho-rhoConst
203      - replace call find_rho to find_rhonum

419     o AIM: near surface temp evaluated from Pot.Temp: fixed for Part Cell ;
420          + change Evap over land. (update aim.5l_cs output)
421     o added missing .cvsignores and made uniform across expts
422     o changed configuration of tidal_basin_2d expt
423     o added pkg/debug functions for tracing code in fatal crashes
424     o tidied pkg/monitor to use MONITOR_OPTIONS.h
425     o new fn in pkg/monitor to stop model if solution grows too big
426     o removed lots of single quotes from comments
427    
428    checkpoint50e_post
429    o make KPP work with PTRACERS
430     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
431       nearly a copy of kpp_transport_s
432     - there is no analogue to SurfaceTendencyS, so I have to use
433       gPtr(of the surface layer) instead
434    o add a new platform SunFire+mpi (SunFire 15000) to genmake
435    checkpoint50e_pre
436    
437    checkpoint50d_post
438    o change kpp output from multiple-record state files to single-record state
439      files analogous to write_state.F
440    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
441      analogous to the cg2d-related output.
442    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
443      so that writing to internal file fn (with length 512) fails.
444    checkpoint50d_pre
445    
446    checkpoint50c_post
447    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
448    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
449    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
450    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
451    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
452    
453    checkpoint50c_pre
454    Merging from release1_p13:
455    o bug fix for pkg/seaice dynamic solver
456    o Added SEAICE_initialHEFF to pkg/seaice
457    
458    checkpoint50b_post
459    o store u*,v* in gU,V instead of in guNm1,gvNm1
460    o in order to put the momForcing out of the Adams-Bashforth:
461      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
462      to timestep.F
463    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
464    o re-generate output for highly sensitive test-exp:
465       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
466    
467    checkpoint50b_pre
468    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
469    o corrected CPP option mismatch in exf_Bulk... functions for case
470      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
471    
472  checkpoint50a_post  checkpoint50a_post
473  o Bug fix for merging between c50 and KPP.  o Bug fix for merging between c50 and KPP.
