5      ==============================      ==============================
6    
7    o pkg/exf:
8      - fix previous modif in exf_readparms.F (revision 1.66: treatment of
9        optional namelist EXF_NML_OBCS).
10      - add many debug-print (to trace down where pkg/cal error msg comes from)
11    o pkg/mom_vecinv/mom_vi_hdissip.F
12      - rearrange loops so that vectorization is improved and in particular
13        the adjoint routine vectorizes. The code is a little longer now, but I
14        think easier to read.
15        Note: CPP-flag MOM_VI_ORIGINAL_VISCA4 is not tested.
16    o pkg/seaice:
17      - allow to specify initial seaice velocity from files (uIceFile,vIceFile)
18    o pkg/exch2:
19      - alternative code (without tile x tile matrix) for cumulated (global) sum;
20        used as default; keep using matrix version in adjustment.cs-32x32x1.
21    o tools/build_options:
22      - after merging some MPI and/or multi-threads specific optfiles so that
23        the modified default optfile support both built (using genmake2 -mpi
24        for the MPI built, using genmake2 -omp for OpenMP built),
25        move now obsolete optfiles to tools/build_options/unsupported/
26       (add copy of email sent to support list in doc/optfiles_changes.txt)
27    
28    checkpoint63c (2011/09/28)
29    o pkg/ebm:
30      - fix ebm_zonalmean.F for several procs in Ydir (nPy > 1); update output of
31        test exp. global_ocean_ebm (affects machine truncation, 12 digits for cg2d)
32    o pkg/seaice (SItracer pickup)
33    * Simple code for pickup of SItracer fields (#define ALLOW_SITRACER)
34      To be done:
35      - thorough testing of missing fields in S/R seaice_read_pickup
36      - thorough matching between generic tracers and specific fields used
37        (e.g. volume-weighted age, area-weighted age, salinity, ...)
38    o pkg/grdchk:
39      - all procs calculate and print finite-difference gradient (for testreport)
40      - change description output used by testreport;
41      - AD testing: also compare and report Finite-difference gradient;
42        => update all output_adm*.txt
43    o test exp. global_ocean_ebm:
44      - switch back useRealFreshWaterFlux (no problem anymore with run-off);
45        and turn on exactConserve; update (fwd) output.
46    o pkg/seaice (LSR):
47      - print to STDOUT number of solver iterations at SEAICE_monFreq interval.
48      - modify solver to deal cleanly with u/v switch at face edges (CS-grid):
49        * identical results with non-CS topology (but save up to half of EXCH calls)
50        * no much changes in cs-32 verification tests since no ice at face edges
51         (differences due to convergence criteria, since nb of iterations changed)
52        * expect some differences on lat-lon-cap grid.
53        update FWD results of global_ocean.cs32x15 test exp. (icedyn & seaice)
54    o pkg/exch2:
55      - add new CPP option to disable Cumul-Sum matrix (to save storage when using
56        many tiles); until alternative coding is added, just add a stop.
57    o pkg/kpp:
58      - move ptracer/salt correction to KPP diffusivity from calc_3d_diffusivity.F
59        to S/R KPP_CALC_DIFF_PTR (+ add tracer-index to argument list).
60    o optfiles:
61      - merged few MPI specific (*+mpi*) and multi-threads specific (*+mth) optfiles
62        into corresponding standard one, which now support different build:
63        (when using "genmake2 -mpi" for MPI built, "genmake2 -omp" for OpenMP built)
64      - add "darwin_amd64_gfortran" optfile (initially from Constantinos, tested by Gael)
65    o pkg/obcs (seaice):
66      - add missing EXCH for uIce,vIce after applying OBCS;
67      - remove S/R EXF_SWAPFFIELDS_X/Y , disable S/R EXF_SET_OBCS_X/Y by adding
68        argument = number of levels to S/R EXF_SWAPFFIELDS_XZ/YZ and S/R
69        EXF_SET_OBCS_XZ/YZ ; update obcs_exf_load.F;
70      - fix EXF_SET_OBCS_XZ/YZ for multi-threaded (assuming loaded arrays are shared)
71      - verification exp. seaice_obcs: split domain in 2 tiles ; add SIZE.h_mpi
72        and eedata.mth for MPI and mutlti-threaded testing.
73    o pkg/flt:
74      - make FLT EXCH working with multi-threads (and MPI + multi-threads);
75      - use buffer for floats IO (trajectories & profiles); size set in FLT_SIZE.h;
76      - fix pickup and trajectories + profiles output with multi-threads;
77      - add parameter to select group of fields to write along trajectory and
78        profile (default unchanged);
79      - only call PORT_RAND* function when flt_noise <> 0;
80      - add multi-threaded test for verification exp. flt_example.
81    o eesupp/src:
82      - fix S/R ALL_PROC_DIE for MPI+multi-threads.
83      - USE_OMP_THREADING: check that number of threads (from eedata) matches
84        actual number (from env.var. setting).
85    o pkg/ebm:
86      - fix multi-threading in ebm_area_t.F ; clean-up EBM.h header file.
87      - add multi-threaded test for verification exp. global_ocean_ebm
88    
89    checkpoint63b (2011/08/29)
90    o pkg/ebm:
91      - fix sign of runoff;
92      - update directly forcing fields (Qnet,EmPmR) to use standard
93        external_forcing_surf.F (remove ebm_forcing_surf.F);
94      - avoid loading forcing fields a 2nd time (1rst time from ini_forcing.F);
95      - set either tauThetaClimRelax (in data) or tauThetaZonRelax (in data.ebm)
96        and apply relaxation towards corresponding SST field (2-D map or ZonAver).
97      - update global_ocean_ebm parameters file data and update output (fwd+ad).
98    o verification/matrix_example:
99      - split domain in 8 tiles (2x4); add SIZE.h_mpi and eedata.mth for
100        MPI and mutlti-threaded testing.
101    o pkg/matrix:
102      - change name of S/R MATRIX_INIT to S/R MATRIX_INIT_VARIA ;

105      - use standard DIFFERENT_MULTIPLE function;
106      - add MATRIX_OPTIONS.h
107    o verification/matrix_example:
108       To allow to split the domain in several tiles, change the domain size
109        from 31x31 to 32x32 by adding 1 row (on Southern side) + 1 column (on
110        Western side) of land points.
111    o (*_)write_pickup:
112      - fix few bugs in mypackage_read/write_pickup.F
113      - in MDS_WR_METAFILES calls, replace "myTime" by a local copy into

116      - fix initialisation of main diagonal matrix (for overlap values)
117    o tools/build_options:

120      - linux_amd64_gfortran: merge +mpi_generic version into standard optfile:
121        * move IEEE flags to DEVEL section; take IEEE flags from +mpi_generic ;
122        * FAST case: for now, keep -O3 with ini_masks_etc.F in NOOPTFILES list;
123        and use "-devel" testreport option for standard testing on baudelaire.
124    o pkg/grdchk:
125      - Assume that all gradient-check position are within the same tile
126        corresponding to global indices (iGloTile,jGloTile) and that

156      - fix some of the problems with OBCS in stream-function calculation.
157    o pkg/exf/exf_readparms.F
158      - make treatment of optional namelists (EXF_NML_04, EXF_NML_SGRUNOFF,
159        EXF_NML_OBCS) more consistent, so that you need not have these lists
160        in data.exf when they are not used.
