5      ==============================      ==============================
6    
7  o model/src/ini_curvilinear_grid.F:  o pkg/mdsio, writelocal:
8       works also in multi-threaded when LOCBIN_IO_THREAD_SAFE is undefined
9       (remove the STOP): uses shared buffer IO to store data from all threads
10       and then let master-thread write nThreads tiles.
11    o pkg/mdsio (read/write field):
12     - tiled IO done in 1 piece (all levels at a time);
13     - new header file "MDSIO_BUFF_3D.h" with 3-D buffers.
14     - multi-threaded: allow to read/write local (non-shared) array
15       (was already working with singleCpuIO ; now works also without);
16       => no longer needs barrier call after reading a file (added inside
17       mds_read/write field).
18     - move barrier calls outside gather/scatter_2d to mds_read/write_field
19    o pkg/obcs/exf
20      - exf_getffieldrec.F: add a few ". _d 0" and
21                            add code to catch the case fldperiod = 0.  
22      - obcs_precribe_read.F: change if statements so that they match
23                              the variable type (_RL)
24      - add a separate exf_iprec_obcs to exf_set_obcs (by default equal to
25        exf_iprec) as part of namelist EXF_NML_01
26    o pkg/mdsio:
27      - read/write tiled (local) files: read/write 1-level tile chunk at a time
28        (instead of segment of length sNx); expected to speed up tiled IO.
29    o pkg/exch2:
30      - take buffer copy from/to array out of S/R exch2_send/recv into new
31        S/R exch2_put/get ; Exch of local variable now works with MPI+MTH
32        (tested by removing commom block statement in SOLVE_FOR_PRESSURE.h).
33      - ad version of send/recv no longer needed (but needs exch2_ad_put/ad_get)
34      - simplify argument list of S/R exch2_get_uv_bounds and exch2_get_scal_bounds
35        (which replaces exch2_get_recv_bounds & exch2_get_send_bounds) by
36        including Topology header file (and common blocks).
37      - implement EXCH_IGNORE_CORNERS in scalar exchange (rx1);
38        remove 2nd exch call in exch2_s3d_rx (no longer needed).
39      - document S/R arg. list (+ update some comments)
40    o pkg/seaice:
41      - added SEAICE_CLIM_AIR code, which permits modulation of surface air
42        temperature and humidity over sea ice based on climatological values.
43      - clean up computation of Hibler+Bryan (1987) stress coupling for the case
44        of LSR (this change is expected to change the results slightly because now
45        it uses slightly difference moduli from the second last LSR solution, but
46        that is more consistent with the stress computations; this part of the code
47        is not tested in the verification experiments)
48      - fix diagnostics for flux of ice in case of B-grid
49      - turn strain rates eij and press into global fields within global
50        common block in SEAICE.h for more straighforward diagnostics
51      - fix diagnostics for principal stress components, press, zeta, eta
52        to give something meaning full
53    o change tiling of global_ocean.cs32x15 (12 tiles, 32x16) and generate
54      new output (all 4 tests) using default rotationPeriod.
55    o pkg KPP:
56      - add flag (LimitHblStable) to avoid limiting BL depth under stable conditions
57      - fix vertical indices in RI_IWMIX (match between KPP grid from 0 to Nr+1
58        and normal grid from 1 to Nr)
59    o Fix computations of L4rdt in mom_calc_visc.F
60    o eesupp:
61      new S/R ALL_PROC_DIE (like EEDIE, without irrelevant threads err msg):
62      should be called before a "stop" if we know that all process are going
63      to stop; if one Proc does call this S/R, will hang in MPI_FINALISE.
64    
65    checkpoint61o
66    o pkg/exch2: change check_depths to issue just a warning (instead of error+stop)
67    o model/src/ini_curvilinear_grid.F:
68     compute angleSin/CosC when they are not read from a file     compute angleSin/CosC when they are not read from a file
69  o pkg/seaice:  o pkg/seaice:
70     add pseudo time stepping for LSOR     add pseudo time stepping for LSOR
71  o pkg/exch2:  o pkg/exch2:
72     temporary fix for exch2_s3d_rx; update results of exp. hs94.cs-32x32x5.impIGW     temporary fix for exch2_s3d_rx; update results of exp. hs94.cs-32x32x5.impIGW
73  o pkg/seaice:  o pkg/seaice:
74     Adding separate sea ice albedo and drag coefficients in Southern Ocean     Adding separate sea ice albedo, drag coefficients, and HO in Southern
75     from those in Arctic Ocean.  See *_south in SEAICE_PARAMS.h     Ocean from those in Arctic Ocean.  See *_south in SEAICE_PARAMS.h
76  o SingleCpuIO:  o SingleCpuIO:
77     fix bug put before chkp61n (May 11), when more than 2 MPI cpu are used.     fix bug put before chkp61n (May 11), when more than 2 MPI cpu are used.
