4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o adjustment.cs-32x32x1: changed to oceanic test with 1 continent
8      + use 48 tiles (16x8): this will allow to test "blank tiles".
9    o start to test MPI + multi-threaded (change testreport to skip tests
10      where number of tiles do not match).
11    o genmake2: add option "-omp" to turn on Open-MP ;
12      passed to testreport (if using -mth) ; merge few (*+mth) optfiles.
13    o pkg/exch2 (+ utils/exch2): ignore blank tiles (instead of removing them)
14      and keep the original tile numbering. Note: compatible with old
15      W2_EXCH2_TOPOLOGY.h & w2_e2setup.F topology files.
16    
17    checkpoint61l
18    o Overlaps had been forgotten in calculating ijk keys : fixed
19    o fix cyrus makedepend for gcc 4.4
20    o experiment fizhi-cs-aqualev20:
21      switching to new version of S/R GETPWHERE (#define TRY_NEW_GETPWHERE)
22      and generate new output. Note: new output is much closer to the old
23      one (v1.8) generated with pgf77 -O2 on Mar 14 2007 than it is from
24      the previous one (v1.9) generated with pgf77 -O0 on Jun 13 2007.
25    o pkg/fizhi:
26     - change to avoid indices going deliberately over array-bounds
27     - remove unnecessary MPI stuff
28     - perpetual spring equinox with "#define FIZHI_USE_FIXED_DAY"
29     - new version of S/R GETPWHERE available with #define TRY_NEW_GETPWHERE:
30       does not go over array-bounds and therefore returns reliable output.
31     - in fizhi_driver.F & fizhi_turb.F, fix "get_alarm" calls:
32       this S/R has 4 output arguments, which are used inside "get_alarm";
33       when it is called with the same variable "ndum" in place of several
34       output arguments, this produces weird side effect inside "get_alarm"
35      (e.g., datein=dates(n) is overwritten by timein=times(n) since both
36       datein & timein, resp. 2nd and 3rd arg., are pointed to the same "ndum"
37       address) and produces error.
38    o lab_sea experiment: change from 2x1 tiles to 2x2 tiles and regenerate output
39    o pkg/seaice: fix bug in new version of S/R SEAICE_LSR.F:
40       update lab_sea.lsr & lab_sea.salt_plume results
41    o pkg/seaice:
42      Major overhaul of the LSOR solver: change discretization from original
43      finite differences to finite volume. The old routine is still in the
44      file seaice_lsr.F and can be turned on with the CPP-flag
45      SEAICE_OLD_AND_BAD_DISCRETIZATION
46      Along with this change, the discretization of the strain rates is changed.
47      The same flag turns on the old discretization in seaice_calc_strainrates.F
48      All verification experiments with seaice are affected (except for
49      seaice_exf_offline); global_ocean.cs32x15/input.icedyn recovers the old
50      results by setting the above flag.
51      Further changes involve changes in defaults:
52      - ALLOW_FLOODING is defined and turned on by default
53      - SEAICEadvSnow = .true. is now the default
54      - SEAICEadvSalt = .true. is now the default
55      - SEAICEadvAge  = .true. is now the default
56      - SEAICE_clipVelocities  = .false. is now the default
57                                         (as per J. Zhang's recommendation)
58      - B-grid, and thus not tested: SEAICE_TEST_ICE_STRESS_1/EXPLICIT_SSH_SLOPE
59        is defined, SEAICE_TEST_ICE_STRESS_1 is renamed into SEAICE_BICE_STRESS
60      - seaice_growth: replace computation of UG by a simple copy from wspeed
61    
62    checkpoint61k
63    o pkg/seaice: a few bug fixes mostly concerning the metric terms:
64      seaice_lsr: fixed a few metric terms,
65                  affects lab_sea.lsr, lab_sea.salt_plume, seaice_obcs
66                  add more debugging diagnostics
67      seaice_evp: removed superfluous many metric terms of FV discretization
68                  of stress divergence
69                  affects lab_sea, lab_sea.hb87
70      seaice_ocean_stress: removed superfluous many metric terms of FV discretization
71                  of stress divergence for non-evp solver
72                  (this part is not tested anywhere)
73      seaice_calc_strainrates: fixed a bug in no-slip boundary conditions,
74                  they were effectively only half slip
75                  affects lab_sea.hb87
76      updated all relevant verification experiments (except lab_sea//output_adm.txt
77        which was left over, but fails at level 7 & 6)
78    
79    checkpoint61j
80    o pkg/seaice: turn a few hard wired parameters into run time parameters
81    o pkg/seaice/exf/monitor: turn netcdf coordinate variable T into model
82      time in seconds as promised by the usints in seaice_monitor and exf_monitor
83    o pkg/mnc: fix the coordinate variables for multi-tile curvi-linear grids
84      that are not cubed-sphere grids
85    o pkg/seaice: fix a bug for the rare case of SEAICE_VECTORIZE_LSR
86    o pkg/ctrl:
87      fix bug in ctrl_depth_ini.F (EXCH_XYZ was applied to 2-D field xx_r_low)
88    o non-hydrostatic (calc_gw.F):
89      fix viscA4 on CS-grid + fix diagnostics: Wm_Diss & Wm_Advec
90      update output of exp. global_ocean.cs32x15.viscA4
91    o remove backward compatibility for thetaMin,phiMin
92      (replaced by xgOrigin,ygOrigin on Jan 27, 2009)
93    o pkg/exf: fix a serious bug in exf_set_uv.F: do a rotation of the
94      interpolated wind field not only for curvilineargrid=.true., but also
95      for a rotated grid (rotateGrid=.true.)
96  o pkg/exf: add capability to bypass interpolation for runoff  o pkg/exf: add capability to bypass interpolation for runoff
