5      ==============================      ==============================
6    
7    o pkg/shelfice:
8      - add parameterisation of advective-diffusive flux into the ice shelf
9        according to Holland and Jenkins (1999), eq.22-33, as suggested by Jan De Ryd
10      - simply eps3/3a computation
11    o eesupp:
12     - add new CPP option (DISCONNECTED_TILES) to disconnect tiles (no exchange
13       between tiles, just fill-in edges assuming locally periodic subdomain) and
14       add corresponding exchange subroutines (EXCH0);
15     - new CG-solver version (_EX0) for disconnected-tiles special case.
16    o model/src (CG-solvers):
17     - modify Single-Reduction version (CG2D_SR) in case cg2dMaxIters is reached
18       (similar final residual output and max-Iter number as with standard version);
19     - allows to store and use lowest-residual solution (standard & _SR versions);
20     - cleaning up (remove old, commented out code, LETS_MAKE_JAM ...).
21     - by default, also compile CG2D_SR version (define ALLOW_SRCG in CPP_OPTIONS.h)
22    o eesup/src:
23     - global_vec_sum.F cleaning: add a BARRIER ; update comments ; remove ndef
24       ALWAYS_USE_MPI (no longer needed after fixing usingMPI settings - March 2012)
25    o pkg/salt_plume added to lab_sea/input_ad.noseaicedyn
26    
27    checkpoint63m (2012/04/27)
28    o pkg/shelfice:
29     - account for partical cells in surface level below ice-shelf for hydrostatic
30       pressure calculion (set uniformFreeSurfLev to F); update isomip experiments.
31    o ad test experiments:
32     - update and rename to "ad_optfile.local" local AD-optfile specific to a
33       particular adjoint verification experiment (in verification/*/code_ad/)
34    o pkg/seaice & pkg/exf:
35     - Part two of ECCO-CLIVAR code merges.
36       Completes merge of seaice area relax. code.
37       Requires unified CPP option EXF_ALLOW_SEAICE_RELAX
38       to be set in EXF_OPTIONS.h since this pkg controls its I/O
39       (and avoids second CPP option in SEAICE_OPTIONS.h)
40     - change default value of costIceStart & costIceEnd to a valid date.
41     - add snowPrecip to HSNOW in seaice_growth
42    o pkg/ptracers:
43     - move ptracers summary and setup check into separated S/R ; add a check for
44       valid PTRACERS_Iter0 value (error+stop or just warning).
45    o pkg/cal (+ pkg/ecco):
46     - avoid calling a S/R with 2 times the same arg (FWD: unless both are only used
47       as input; and for AD, unless both are not differentiable (e.g., k index)).
48    o model/src:
49     - define internal flag "uniformFreeSurfLev" (=T when free-surface level-index
50       is everywhere k=1) to speed-up some calculations (by pass kSurf reference);
51       temporary set to usingZCoords value (to be changed to F when using shelfice).
52     - hydrostatic pressure: implement partial cell near the surface also for
53       Z-coordinates (for the case where uniformFreeSurfLev=F); replace test on
54       usingZCoords with test on uniformFreeSurfLev where needed (in NonHyd code).
55    o pkg/ctrl/ctrl_init.F:
56     - add a formal parameter to s/r ctrl_init_rec to print
57       xx_$(ctrl_valiable)_file for easier debugging
58     - move call of cal_* routines into the if-block where they are really
59       needed so that xx_$(ctrl_variable)_period can be 0 or -12 without having
60       to specify a startdate
61    o pkg/seaice:
62     - update comments in SEAICE_OPTIONS.h (+ similar update of lab_sea/code and
63       global_ocean.cs32x15/code versions).
64     - turn on seaice Multi-category (in data.seaice, SEAICE_multDim=7) for
65       verification experiment global_ocean.cs32x15.seaice and update results.
66  o pkg/exf:  o pkg/exf:
67   - new S/R EXF_GETFIELD_START to return starting-time of a forcing field   - new S/R EXF_GETFIELD_START to return starting-time of a forcing field
68     (according to useExfYearlyFields).     (according to useExfYearlyFields).
