5      ==============================      ==============================
6    
7  o pkg/seaice :  o model/src/config_check.F: add a check for OLx>sNx/OLy>sNy
8    o verification/lab_sea
9      * #undef SEAICE_EXCLUDE_FOR_EXACT_AD_TESTING
10      * #define ALLOW_SST_CONTROL & ALLOW_SST_CONTROL
11      * nTimeSteps 3 -> 4
12      * changed reference output accordingly
13    o pkg/ctrl:
14      * fix ctrl_get_gen for xx_sst, xx_sss
15    o pkg/fizhi:
16      - fix 2 calls to S/R GRD2MSC (argument igrd) in update_earth_exports.F
17        update results of exp. fizhi-cs-32x32x40 (fail with only 6 digits for cg2d)
18      - by default, use new version of S/R GETPWHERE (#define TRY_NEW_GETPWHERE);
19        fix few out-of-bounds indices in referencing vars (initialise igrd to 1);
20        clean-up fizhi_turb.F (remove unused & uninitialised qdiaglsm array).
21    o pkg/gmredi:
22      - add diagnostic of Redi (main diagnonal) vertical diffusive flux of Temp
23    o pkg/fizhi:
24      - fix few initialisation and multi-tile Pb: aqualev & gridalt now pass the
25        (old)aces open64 tuv test.
26    o pkg/icefront: fix bug and reorder loop in icefront_init_varia.F
27    o pkg/mom_vecinv:
28      - fix 1 loop range in mom_vecinv.F to be like all the other loops which
29        set/update gu,gv/Diss (fix Pb of uninitialised fVerUkp in admom_vecinv
30        with non-lin free-surf).
31    o model/src: move k-loop outside of i/j-loops when (re-)computing R_low
32      in ini/update_masks_etc.F in order to avoid -O3 optimization problems with
33      some compilers (gfortran 4.6.0 on MacOS)
34    o momentum:
35      - separate fVer?(:,:,kUp) & fVer?(:,:,kDown) in argument list of MOM_FLUXFORM
36        & MOM_VECINV subroutines (to help TAF). This fixes Pb of uninitialised
37        fVer?(kUp) in admom_fluxform with non-lin free-surf or bottom control.
38    
39    checkpoint63k (2012/03/17)
40    o model/src:
41       - selectAddFluid (ALLOW_ADDFLUID): add missing term in horizontal momentum
42         flux-form (mom_fluxform.F) and vertical momentum (calc_gw.F) equations.
43       - SOLVE_DIAGONAL: switch default to use adjoinable & vectorized version
44         (#undef SOLVE_DIAGONAL_LOWMEMORY); update output of exp. front_relax.bvp.
45    o model/src: solve_*diagonal.F
46       - replace division with multiplication by inverse (similar to original version)
47         update output of AD exp. global_ocean.90x40x15.
48       - fix pkg/gmredi/gmredi_calc_psi_bvp.F & pkg/ggl90/ggl90_calc.F
49         to enable the use of the vectorized & differentiable solve_tridiagonal.F
50       - test exp. global_ocean.90x40x15/input_ad: switch to advection scheme 20 for
51         vertical advection (to get solve_tridiagonal tested in AD mode).
52    o pkg/seaice: ECCO-CLIVAR merge:
53      1. seaice AREA relaxation
54         * CPP option: SEAICE_ALLOW_AREA_RELAXATION
55         * runtime flag: SEAICE_tauAreaObsRelax
56      2. modified global mean cost imbalance code: CPP option
57          ALLOW_SSH_GLOBMEAN_COST_CONTRIBUTION
58    o another iteration on solve_*diagonal.F
59       Make choices independent of AUTODIFF
60       Default will be the adjoinable vectorized version.
61       Alternative choices are:
62       * non-adjoinable original version with low memory footprint:
63         #define SOLVE_DIAGONAL_LOWMEMORY
64       * still adjoinable but does not vectorize (k as inner-most loop):
65         #define SOLVE_DIAGONAL_KINNER (keeping SOLVE_DIAGONAL_LOWMEMORY undef)
66    o testreport
67     - add option to use a home made wrapper around "make"
68     - remove MITGCM_IEEE env. variable (no longer active)
69    o pkg/shelfice
70     - improve computation of friction velocity for velocity dependent
71       exchange coefficients: include velocities into SHELFICEBoundaryLayer
72       block to average velocities vertically
73     - add TAF store directives for SHI_ALLOW_GAMMAFRICT
74    o Modify diagonal solvers, now three versions (upon request):
75      #ifndef SOLVE_DIAGONAL_AUTODIFF
76        1. default version (dating back a while ago)
77      #else /* def SOLVE_DIAGONAL_AUTODIFF */
78      # ifdef SOLVE_DIAGONAL_KINNER
79        2. adjoinable version with k-innermost loop (G. Forget)
80      # else
81        3. adjoinable vectorized version of 2.
82      # endif
83      #endif /* SOLVE_DIAGONAL_AUTODIFF */
84      All flags are currently set within routines, but could/should be moved to CPP-options.
85      Array bounds for 1. are as before, for 2.,3. cover the entire domain
86      (could be changed for 1. too).
87    o verification/lab_sea (fwd):
88      - update the 4 fwd lab_sea test experiment: no longer SEAICE_GROWTH_LEGACY,
89        use 7 categories (except hb87), new solve4temp params (except salt_plume),
90        constant salinity (=4) or variable salinity (salt_plume) done through
91        SItracer.
92    o pkg/seaice:
93      - rename parameters: SIsalFrac to SEAICE_saltFrac & SIsal0 to SEAICE_salt0;
94      - remove old parameters ( SEAICE_freeze, SEAICEturbFluxFormula, SEAICE_gamma_t,
95         SEAICE_gamma_t_frz, SEAICE_availHeatTaper & SEAICE_availHeatFracFrz)
96        from SEAICE_PARMS.h ; still need to fix seaice_cost_sst.F (broken when
97        SEAICE_freeze got retired) but already better than previously with
98        SEAICE_freeze=123456.7 deg.C;
99      - move setting of facOpenGrow/Melt from SEAICE_INIT_FIXED to SEAICE_READPARMS
100        (safer multi-threaded setting); always set SEAICEuseEVP;
101      - setting of ocean-ice turb. flux coeff: moved from SEAICE_CHECK to
102        SEAICE_READPARMS & SEAICE_INIT_FIXED (this fixes wrong summary report);
103        stop if multiple specifications for the same coeff; make sure default
104        SEAICE_mcPheePiston is compatible with drF(1) & deltaT.
105    o pkg/obcs:
106      - allow to switch to upwind 1rst order advection scheme for the advective
107        flux computation at the open-boundary; disabled for adjoint built.
108    o pkg/ptracers:
109      - rename PTRACERS_RESTART.h -> PTRACERS_START.h
110      - rename ptracers_fields_blocking_exchanges.F -> ptracers_fields_blocking_exch.F
111      - add parameter to decide when to start a tracer; use internal flag to
112        know which tracer to step-forward; switch this internal flag at the top
113        of forward_step.F (new S/R PTRACERS_SWITCH_ONOFF); for now, not enabled
114        for adjoint built.
115    o pkg/seaice:
116      - add SEAICE_SIZE.h anywhere in the code where SEAICE.h is included ;
117      - move MULTDIM declaration and setting from SEAICE.h to SEAICE_SIZE.h ;
118      - keep experiment offline_exf_seaice truly single category (set MULTDIM=1).
119    o pkg/ecco:
120      - fix writing of output file DiagnosCost_ClimSalt/Theta
121        and DiagnosCost_DriftSalt/Theta (if multi-tiles per proc).
122    o pkg/seaice:
123      - add missing initialisation of COR_ICE array in dynsolver.F
124      - merging SEAICE_MULTICATEGORY define and undef cases. Now the same code is
125        compiled either way, and is tested in all exps (multidim was only tested
126        in lab_sea ad before).
127      - cosmetic change to prepare for future addition of ITD. no change to results.
128        no defaults change.
129      - added run time param SEAICE_multDim (7 for SEAICE_MULTICATEGORY, 1 otherwise).
130      - by lack of adequate verification experiments, I further used custom versions
131        of global_ocean.cs32x15 to test multicat or not, with pickup or not. All
132        should be correct.
133      - avoid recomputations in ad.
134    o array initialisation in adjoint mode:
135      1) pkg/mom_common/mom_calc_ke.F:
136        add full array initialisation of KE inside mom_calc_ke.F (ALLOW_AUTODIFF_TAMC):
137        The S/R which calls MOM_CALC_KE initialises KE but in some recomputation
138        part this initialisation is gone, resulting in Floating Point Exception
139        (caught by open64 compiler with debug option).
140      2) model/src/convective_weights.F
141        set output convectCount over the full array range (instead of doing
142        an update): this fix a similar issue when called within recomputation (adjoint)
143        which could by-pass the initialisation (normally done in the caller S/R).
144    o pkg/seaice:
145    - final version of turbulent flux params, as agreed at MIT ice meet:    - final version of turbulent flux params, as agreed at MIT ice meet:
