5      ==============================      ==============================
6    checkpoint58s_post
7    o pkg/exf: moved exf_init_runoff.F to exf_init.F and exf_set_gen.F
8      changed exf_set_gen.F so that
9        genperiod=0 means input file is one time-constant field and
10        genperiod=-12 means input file contains 12 monthly means
11    o CG2D: use pre-computed solver main-diagonal (stored in common block);
12      this affects truncation error ; generate new output file for exp. which
13      fails: exp4(12d), fizhi-cs-aqualev20(12d), front_relax(10d),
14        global_ocean.90x40x15(10d), global_ocean.cs32x15(10d).thsice(11d).viscA4(10d),
15        ideal_2D_oce(10d), internal_wave(09d), isomip.htd(11d), matrix_example(07d),
16        MLAdjust(4x11d,12d), natl_box(11d), rotating_tank(12d),
17        tutorial_global_oce_in_p(10d), tutorial_plume_on_slope(11d),
18        vermix(12d).ggl90(12d).my82(11d).opps(12d).pp81(11d)
19    o start implementation of deep-atmosphere and anelastic formulation
20    o verification: remove 2nd copy of input files and use script "prepare_run"
21      to make a symbolic link to the 1rst copy (reduce downloaded size by ~81.M)
22    o mom_common/vecinv/fluxform: fix a few initialisation isssues
23    o profiles: fix for multithreaded case
24    
25    o diagnostics: rename few diags:
26      s/'PRESSURE'/'RCENTER '/g
27      s/'TICE    '/'oceFreez'/g
28      s/'TAUX    '/'oceTAUX '/g
29      s/'TAUY    '/'oceTAUY '/g
30      s/'SWFLUX  '/'oceQsw  '/g
31      s/DIFx/DFxE/g
32      s/DIFy/DFyE/g
33      and add few ocean-forcing diagnostics:
34      atmPload, sIceLoad, oceQnet, oceFWflx, oceSflux, surForcT & surForcS
35    o modifications to pkg/seaice/growth.F and budget.F, which change results of
36      lab_sea experiment: HSNOW was sometimes treated as effective and sometimes
37      as actual snow thickness.  It now refers everywhere to effective snow
38      thickness, meaning that for non-zero AREA, actual thickness is HEFF/AREA.
39    
40    checkpoint58r_post
41    o modifications to pkg/seaice/growth.F, which change results of
42      lab_sea experiment: fixes pertain to melting snow over open water, to
43      masking EVAP under sea ice, and to using the correct AREA variable for
44      computations of EVAP, PRECIP, HSNOW, and GHEFF
45    o add ability to read bathy, salt, and theta using MNC (off by def)
46    o add flooding algorithm and advection of HSNOW for pkg/seaice;
47      both are turned off by default and do no change any results
48    o seaice advection with pkg/thsice: a step toward the use of non-linear
49      advection scheme, but #ifdef or commented out for now (requires more EXCH).
50    o use standard version of PTRACERS_INI_VARIA in tutorial_tracer_adjsens
51      (identical results) and the standard version of EXTERNAL_FIELDS_LOAD
52      in natl_box (affects results @ truncation level: update output.txt)
53    o multi-threading and IO:
54      - replace some call to MDSIO S/R by the corresponding READ/WRITE_FLD S/R.
55      - remove most of BEGIN_MASTER/ END_MASTER around READ/WRITE_FLD S/R calls
56        (needed to work with SingleCpuIO): tested in all verif. exp.
57    o GAD: use simpler DST3 formulation as default (old version left within #ifdef)
58      affects the results (but none of the verification test uses this scheme).
59    o Adding some pkg/diagnostics capability to pkg/seaice
60      (will certainly be subject to changes)
61    o ctrl: adding new control variables:
62      lwflux, lwdown, evap, snowprecip, apressure, runoff
63    
64    checkpoint58q_post
65    o added CPP_EEOPTIONS.h flag DISABLE_MPI_READY_TO_RECEIVE.  Speeds up
66      1/6-deg Southern Ocean configuration by 8% on IBM Datastar and
67      high_res_cube configuration by 4% on Columbia.
68    o clean-up multi-threaded problems (reported by debugger tcheck on ACES);
69      add (in global_with_exf/code) a version of EXF_INTERP_READ without
70      dynamical allocation (seems to work in multi-threaded).
71    o new function "MASTER_CPU_IO" (=T if master thread & master CPU, if using
72      single CPU io) so that TAF does not have to see EESUPPORT.h
73    o pkg/seaice: implement sea-ice loading (when using RealFreshWaterFlux)
74    
75    checkpoint58p_post
76    o obcs: stop if obcs is used with useCDscheme = .true.
77    o shelfice:
78     - fix a sign error so that no slip at shelfice interface works
79     - remove stop for combination non-hydrostatic code and shelfice. That does
80       not mean, that the results are correct, but at least they are numerically
81       stable
82    o diagnoctics: modify UVELPHI and VVELPHI to include hfac (i.e. mass-weighted)
83    o added adjoint exch routined for all exch*3d* routines
84      and updated flow directives
85    
86    checkpoint58o_post
87    o replace calls to EXCH_Z & EXCH_UV_AGRID: use the new _3D_ version ;
88      remove old subroutines (_XY_ & _XYZ_); update the adjoint version.
89    o change controling S/R for writing pickup file (new S/R do_write_pickup)
90      and clean-up reading/writing of pickup files.
91    o fix local version of read/write pickup (NH part) in rotating_tank/code
92    o simplify EXCH interface:
93     - change _XYZ_ interface to _3D_ subroutine (with 3rd dim in argument list)
94     - not often used EXCH S/R (exch_z, exch_uv_agrid): keep only the _3D_ version
95    o added the regrid package
96    o shelfice:
97     - add a simple boundary layer scheme to reduce noise
98     - fix the indexing in shelfice_u/v_drag so that there will be actually drag
99    
100    checkpoint58n_post
101    o fix globalArea multi-threaded calculation: need to apply GLOBAL_SUM to
102       local variable (not in common block).
103  o lot of small changes for multi-threaded. Most tests (using OMP & ifort) pass.  o lot of small changes for multi-threaded. Most tests (using OMP & ifort) pass.
104    - still problems with pkgs: mnc, exp2, dic, cal, exf (and probably more);    - still problems with pkgs: mnc, exp2, dic, cal, exf (and probably more);
105    - still BEGIN_MASTER/END_MASTER to remove around READ/WRITE_FLD S/R calls    - still BEGIN_MASTER/END_MASTER to remove around READ/WRITE_FLD S/R calls
