7    checkpoint62r (2011/01/24)
8    o testreport:
9     - add option -deloutp (-do) to remove output file after successful run
10     - add option -mfile (-mf) for MPI machile-file and for each test-exp,
11       extract exact list of procs from this file ; adjust COMMAND by
12       replacing TR_MFILE & TR_NPROC with local machile-file & Nb of MPI procs.
13    o pkg/ecco: replace old ineffective way of penalizing deviations from
14      first guess (of obcs) with code by Matt Mazloff
15    o pkg/ctrl: add code that allows the use of ALLOW_OBCS?_CONTROL without
16      exf/cal
17      - ctrl_init: fix initialisation (computation of diffrec) for obcs-ctrl
18        and handle case of obcs?period == 0
19        Not affected by these changes: There is still an inconsistency in
20        the computation of start/endrec for the obcs variables for ALLOW_CAL
21        defined (see comment by Menemenlis, 7-Mar-2003)
22      - make S/R ctrl_get_gen_rec return something meaningful even if
23        ALLOW_CAL is not defined
24      - ctrl_getobcs?: simplify code so that it does not need to use
25                       S/R exf_swapfields
26    o testreport:
27       allow to test MPI with different number of processors for each experiment:
28       create file "SIZE.h.mpi" in each build dir.
29       Note: update of "-command" argument not yet implemented.
30    o model/src, pkg/autodiff, pkg/ecco, pkg/seaice:
31      alleviate the need for additional 3D tapes when using
32      the non-inear free surface in the adjoint. This is done
33      by adding an 'update' of hfacc etc. to their current
34      value at the beginning of forward_step.F.
35    o pkg/seaice
36      seaice_lsr: move stress-divergence computations out of outer pseudo-
37      timestepping loop
38    o pkg/obcs/obcs_prescribe_read.F: move 'CALL OBCS_EXTERNAL_FIELDS_LOAD'
39      up, so that the calls of the ctrl_* subroutines are really at the end
40      of the routine.
41    o pkg/gmredi:
42      allow to specify a 2-D horizontal map and a 1-D vertical profil
43      as scaling factor for Isopycnal diffusivity (Redi) and GM diffusivity.
44    o pkg/seaice:
45      move lsr iterations from seaice_dynsolver to seaice_lsr.
46    o pkg/seaice:
47      reduce memory footprint of seaice mutldim advection tapes,
48      by using a 2D tape independent of the generic_advdiff ones,
49      and setting GAD_AREA=1 etc. rather than GAD_AREA=101 etc.
50    
51    checkpoint62q (2010/12/29)
52    o model/src:
53      - check horizontal grid-spacing for unset or zero/negative values.
54      - change AD test hs94.1x64x5 to be truly a 2-D set-up.
55    o pkg/flt:
56      - use (recent) mdsio S/R MDS_READVEC_LOC instead of local FLT_MDSREADVECTOR
57      - precision of input and output files set according to readBinaryPrec
58        and writeBinaryPrec (previously always 64.b), pickup remains at 64 bits.
59      - initial float position from tiled file was not converted to index space
60        (looks like a bug): fixed to make it similar to initial pos. global file.
61    o global_ocean.cs32x15:
62       change SIZE.h of AD set-up to get same tiling as with MPI.
63       Update output_adm, output_adm.thsice (pass@14) & output_adm.seaice (fail@11)
64    o model/src:
65       add flag to control printing of domain fields (bathymetry, hFac ...) in
66       ini_mask_etc (call to plot_fieds_xy*).
67    o pkg/thsice:
68       if useEXF, some forcing fields are not valid in overlap: fixed by computing
69       over the interior only + apply EXCH at the end (like with SEAICE advection).
70    o pkg/mdsio:
71      - add 2 arguments to S/R MDS_PASS_R4/8toRL/S for overlap size of buffer
72        to copy to/from, so that it can be used to replace MDS_PASS_WH_R8toRL/RS.
73      - change barrier call for safe multi-threads access to 3-D shared buffer.
74      - MDS_READ/WRITEVEC_LOC use buffers from MDSIO_BUFF_3D.h (instead of local ones)
75      - replace call to MDS_PASS_WH_R4/8toRL with call to MDS_PASS_R4/8toRL and
76        remove the 4 S/R MDS_PASS_WH_R4/8toRL/S.
77    o pkg/flt:
78      - add fourth-order Runge-Kutta integration
79      - add basic exch2 support (only 1 facet supported so far!)
80    o pkg/mdsio+rw:
81      new S/R to read local (or tile independent) vector (read counterpart of
82       mds_writevec_loc, and front-end write_glvec_rl/rs).
83    o global_ocean.cs32x15: additional input_ad.seaice experiment
84        that uses pkg/seaice rather than pkg/thsice.
85        (using multidim advection for seaice)
86    o towards more F95 syntax for array specification in namelist:
87      - change "data.diagnostics" (data.ptracers was changed before checkpoint62p)
88        of all verification experiments.
89           e.g.:    line: fields(1,3)='ETAN    ','ETANSQ  ',
90          was changed to: fields(1:2,3)='ETAN    ','ETANSQ  ',
91      - finish adding "-DNML_EXTENDED_F77" to DEFINES list in pgf77 and g77 optfiles
92    o global_ocean.cs32x15: additional input.seaice experiment
93        that uses pkg/seaice rather than pkg/thsice.
94    
95    checkpoint62p (2010/12/17)
96    o pkg/thsice: rename (ad tape index) iicekey as ticekey, and move it
97        to THSICE_SIZE.h to avoid conflict with pkg/seaice.
98    o pkg/seaice: add seaice_diffusion.f seaice_map_thsice.f to adjoint.
99        allow for use of multim. advection in seaice adjoint.
100    o pkg/seaice: add diagnostics for snow precipitation and sublimation flux
101      - first attempt to close budgets by taking into account the freshwater
102        flux implied by the sublimation of snow and ice. So far only the
103        volume budget is closed, turn on with soon-to-be-retired-again CPP-Flag
104        SEAICE_ADD_SUBLIMATION_TO_FWBUDGET
105    o eesupp/src:
106      new S/R with new option (NML_EXTENDED_F77) to change array specification
107      from F95 standard to commonly accepted extended F77 form.
108      This would allow to use F95 syntax in namelist (needed with gfortran 4.4.5)
109      and to revert back to the original syntax (with -DNML_EXTENDED_F77)
110      for less tolerant f77 compiler (e.g., pgf77, g77).
111  o globalFiles:  o globalFiles:
112    commented out in parameter file "data" since it's not safe with MPI    commented out in parameter file "data" since it's not safe with MPI
113    (e.g., wrong on aces); keep it if useSingleCpuIO=T (but not doing much    (e.g., wrong on aces); keep it if useSingleCpuIO=T (but not doing much
