4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/fizhi:
8      - fix few initialisation and multi-tile Pb: aqualev & gridalt now pass the
9        (old)aces open64 tuv test.
10    o pkg/icefront: fix bug and reorder loop in icefront_init_varia.F
11    o pkg/mom_vecinv:
12      - fix 1 loop range in mom_vecinv.F to be like all the other loops which
13        set/update gu,gv/Diss (fix Pb of uninitialised fVerUkp in admom_vecinv
14        with non-lin free-surf).
15    o model/src: move k-loop outside of i/j-loops when (re-)computing R_low
16      in ini/update_masks_etc.F in order to avoid -O3 optimization problems with
17      some compilers (gfortran 4.6.0 on MacOS)
18    o momentum:
19      - separate fVer?(:,:,kUp) & fVer?(:,:,kDown) in argument list of MOM_FLUXFORM
20        & MOM_VECINV subroutines (to help TAF). This fixes Pb of uninitialised
21        fVer?(kUp) in admom_fluxform with non-lin free-surf or bottom control.
22    
23    checkpoint63k (2012/03/17)
24    o model/src:
25       - selectAddFluid (ALLOW_ADDFLUID): add missing term in horizontal momentum
26         flux-form (mom_fluxform.F) and vertical momentum (calc_gw.F) equations.
27       - SOLVE_DIAGONAL: switch default to use adjoinable & vectorized version
28         (#undef SOLVE_DIAGONAL_LOWMEMORY); update output of exp. front_relax.bvp.
29    o model/src: solve_*diagonal.F
30       - replace division with multiplication by inverse (similar to original version)
31         update output of AD exp. global_ocean.90x40x15.
32       - fix pkg/gmredi/gmredi_calc_psi_bvp.F & pkg/ggl90/ggl90_calc.F
33         to enable the use of the vectorized & differentiable solve_tridiagonal.F
34       - test exp. global_ocean.90x40x15/input_ad: switch to advection scheme 20 for
35         vertical advection (to get solve_tridiagonal tested in AD mode).
36    o pkg/seaice: ECCO-CLIVAR merge:
37      1. seaice AREA relaxation
38         * CPP option: SEAICE_ALLOW_AREA_RELAXATION
39         * runtime flag: SEAICE_tauAreaObsRelax
40      2. modified global mean cost imbalance code: CPP option
41          ALLOW_SSH_GLOBMEAN_COST_CONTRIBUTION
42    o another iteration on solve_*diagonal.F
43       Make choices independent of AUTODIFF
44       Default will be the adjoinable vectorized version.
45       Alternative choices are:
46       * non-adjoinable original version with low memory footprint:
47         #define SOLVE_DIAGONAL_LOWMEMORY
48       * still adjoinable but does not vectorize (k as inner-most loop):
49         #define SOLVE_DIAGONAL_KINNER (keeping SOLVE_DIAGONAL_LOWMEMORY undef)
50    o testreport
51     - add option to use a home made wrapper around "make"
52     - remove MITGCM_IEEE env. variable (no longer active)
53    o pkg/shelfice
54     - improve computation of friction velocity for velocity dependent
55       exchange coefficients: include velocities into SHELFICEBoundaryLayer
56       block to average velocities vertically
57     - add TAF store directives for SHI_ALLOW_GAMMAFRICT
58    o Modify diagonal solvers, now three versions (upon request):
59      #ifndef SOLVE_DIAGONAL_AUTODIFF
60        1. default version (dating back a while ago)
61      #else /* def SOLVE_DIAGONAL_AUTODIFF */
62      # ifdef SOLVE_DIAGONAL_KINNER
63        2. adjoinable version with k-innermost loop (G. Forget)
64      # else
65        3. adjoinable vectorized version of 2.
66      # endif
67      #endif /* SOLVE_DIAGONAL_AUTODIFF */
68      All flags are currently set within routines, but could/should be moved to CPP-options.
69      Array bounds for 1. are as before, for 2.,3. cover the entire domain
70      (could be changed for 1. too).
71    o verification/lab_sea (fwd):
72      - update the 4 fwd lab_sea test experiment: no longer SEAICE_GROWTH_LEGACY,
73        use 7 categories (except hb87), new solve4temp params (except salt_plume),
74        constant salinity (=4) or variable salinity (salt_plume) done through
75        SItracer.
76    o pkg/seaice:
77      - rename parameters: SIsalFrac to SEAICE_saltFrac & SIsal0 to SEAICE_salt0;
78      - remove old parameters ( SEAICE_freeze, SEAICEturbFluxFormula, SEAICE_gamma_t,
79         SEAICE_gamma_t_frz, SEAICE_availHeatTaper & SEAICE_availHeatFracFrz)
80        from SEAICE_PARMS.h ; still need to fix seaice_cost_sst.F (broken when
81        SEAICE_freeze got retired) but already better than previously with
82        SEAICE_freeze=123456.7 deg.C;
83      - move setting of facOpenGrow/Melt from SEAICE_INIT_FIXED to SEAICE_READPARMS
84        (safer multi-threaded setting); always set SEAICEuseEVP;
85      - setting of ocean-ice turb. flux coeff: moved from SEAICE_CHECK to
86        SEAICE_READPARMS & SEAICE_INIT_FIXED (this fixes wrong summary report);
87        stop if multiple specifications for the same coeff; make sure default
88        SEAICE_mcPheePiston is compatible with drF(1) & deltaT.
89    o pkg/obcs:
90      - allow to switch to upwind 1rst order advection scheme for the advective
91        flux computation at the open-boundary; disabled for adjoint built.
92    o pkg/ptracers:
93      - rename PTRACERS_RESTART.h -> PTRACERS_START.h
94      - rename ptracers_fields_blocking_exchanges.F -> ptracers_fields_blocking_exch.F
95      - add parameter to decide when to start a tracer; use internal flag to
96        know which tracer to step-forward; switch this internal flag at the top
97        of forward_step.F (new S/R PTRACERS_SWITCH_ONOFF); for now, not enabled
98        for adjoint built.
99  o pkg/seaice:  o pkg/seaice:
100    - add SEAICE_SIZE.h anywhere in the code where SEAICE.h is included ;    - add SEAICE_SIZE.h anywhere in the code where SEAICE.h is included ;
101    - move MULTDIM declaration and setting from SEAICE.h to SEAICE_SIZE.h ;    - move MULTDIM declaration and setting from SEAICE.h to SEAICE_SIZE.h ;
