5      ==============================      ==============================
6    
7    o model/src:
8     - define internal flag "uniformFreeSurfLev" (=T when free-surface level-index
9       is everywhere k=1) to speed-up some calculations (by pass kSurf reference);
10       temporary set to usingZCoords value (to be changed to F when using shelfice).
11     - hydrostatic pressure: implement partial cell near the surface also for
12       Z-coordinates (for the case where uniformFreeSurfLev=F); replace test on
13       usingZCoords with test on uniformFreeSurfLev where needed (in NonHyd code).
14    o pkg/ctrl/ctrl_init.F:
15     - add a formal parameter to s/r ctrl_init_rec to print
16       xx_$(ctrl_valiable)_file for easier debugging
17     - move call of cal_* routines into the if-block where they are really
18       needed so that xx_$(ctrl_variable)_period can be 0 or -12 without having
19       to specify a startdate
20    o pkg/seaice:
21     - update comments in SEAICE_OPTIONS.h (+ similar update of lab_sea/code and
22       global_ocean.cs32x15/code versions).
23     - turn on seaice Multi-category (in data.seaice, SEAICE_multDim=7) for
24       verification experiment global_ocean.cs32x15.seaice and update results.
25    o pkg/exf:
26     - new S/R EXF_GETFIELD_START to return starting-time of a forcing field
27       (according to useExfYearlyFields).
28    o pkg/cal:
29     - move calendar setting & summary (previously in cal_readparams.F) into new
30       S/R CAL_INIT_FIXED to be called later in the initialisation process, once
31       length of the simulation is set (after SET_PARMS call); This is an attempt
32       to fix Pb when, e.g.: pkg/longstep, modifies the length of the run.
33     - For safety: keep a record of pkg/cal parameter settings status
34               to allow to STOP if one pkg/cal S/R is called too early.
35     - add a stop in all basic pkg/cal subroutines if called before setting is done.
36     - modify cal_getdate.F: stop when nothing was returned;
37       if called with myIter=-1, simply retrun modelBaseDate (1,2 = startDate_1,_2);
38       this allows to remove "cal.h" from seaice_read_parms.F & init_mnc_vars.F.
39    
40    checkpoint63l (2012/04/04)
41    o pkg/bbl:
42      - fix call to FIND_RHO_2D in bbl_calc_rho.F (case multi-tiles per proc);
43        update global_with_exf output.yearly.txt file.
44    o pkg/cal:
45      - start to clean-up cal_set.F ; fix for the case where baseTime is non-zero.
46      - remove 2 unsused and very short (1 line only) functions ;
47      - remove unsused subroutines from AD-Diff list.
48    o model/src:
49      - start to implement clean wait to stop in initialization S/R (config_check.F,
50         packages_check.F, ini_parms.F and pkg/obcs/obcs_check.F + pkg/mypackage)
51    o folowing PRINT_MESSAGE changes:
52      - remove reminder multiple print to the same file (STDOUT) when multi-threads.
53    o pkg/bbl:
54      - modification so it can work with z*
55      - replace deltaT with dTtracerLev(k) for asynchronous time stepping
56      - global_with_exf/input.yearly verification; changes output.yearly.txt
57    o eesupp/src:
58      - PRINT_MESSAGE: use OpenMP critical instruction (similar to PRINT_ERROR);
59        writing to unit 0 (if unit=errorMessageUnit) extended to the case myThid=1
60      - CHECK_THREADS: specific code if using OpenMP threading: improve checking of
61        # of threads across processors (e.g., different env OMP_NUM_THREADS setting)
62      - improve special preliminary call to EESET_PARMS (if eedata is read 2 times).
63      - when using MPI, always set usingMPI=T ; set default accordingly and stop
64        if not consistent.
65      - ALL_PROC_DIE: add a BARRIER after MPI_FINALIZE call ; skip this when thread
66        argument is zero (in case called within single-thread section).
67    o pkg/fizhi:
68        clean-up turbulence cold-start switch: decided in fizhi_init_vars.F, stored
69        in common bloc (fizhi_coms.h) and then passed as argument up to S/R TURBIO.
70    o pkg/exch2:
71      - add argument "updateCorners" to S/R exch2_get_uv_bounds (enable to
72        activate EXCH_IGNORE_CORNERS in vector EXCH S/R).
73      - switch 1rst EXCH call to IGNORE_CORNERS (instead of UPDATE_CORNERS)
74        but keep the 2nd with UPDATE_CORNERS: this prevents overwriting good data
75        with bad ones coming from a not-yet-updated halo.
76        This should fix the problem when sNx <> sNy and GCD(sNx,sNy) < 2*Olx.
77    o pkg/frazil:
78        move FrzForcT diag from frazil_diagnostics_state.F to frazil_calc_rhs.F
79        http://mitgcm.org/pipermail/mitgcm-devel/2012-March/005384.html
80    o model/src/config_check.F: add a check for OLx>sNx/OLy>sNy
81    o verification/lab_sea
82      * #undef SEAICE_EXCLUDE_FOR_EXACT_AD_TESTING
83      * #define ALLOW_SST_CONTROL & ALLOW_SST_CONTROL
84      * nTimeSteps 3 -> 4
85      * changed reference output accordingly
86    o pkg/ctrl:
87      * fix ctrl_get_gen for xx_sst, xx_sss
88    o pkg/fizhi:
89      - fix 2 calls to S/R GRD2MSC (argument igrd) in update_earth_exports.F
90        update results of exp. fizhi-cs-32x32x40 (fail with only 6 digits for cg2d)
91      - by default, use new version of S/R GETPWHERE (#define TRY_NEW_GETPWHERE);
92        fix few out-of-bounds indices in referencing vars (initialise igrd to 1);
93        clean-up fizhi_turb.F (remove unused & uninitialised qdiaglsm array).
94    o pkg/gmredi:
95      - add diagnostic of Redi (main diagnonal) vertical diffusive flux of Temp
96    o pkg/fizhi:
97      - fix few initialisation and multi-tile Pb: aqualev & gridalt now pass the
98        (old)aces open64 tuv test.
99    o pkg/icefront: fix bug and reorder loop in icefront_init_varia.F
100    o pkg/mom_vecinv:
101      - fix 1 loop range in mom_vecinv.F to be like all the other loops which
102        set/update gu,gv/Diss (fix Pb of uninitialised fVerUkp in admom_vecinv
103        with non-lin free-surf).
104    o model/src: move k-loop outside of i/j-loops when (re-)computing R_low
105      in ini/update_masks_etc.F in order to avoid -O3 optimization problems with
106      some compilers (gfortran 4.6.0 on MacOS)
107    o momentum:
108      - separate fVer?(:,:,kUp) & fVer?(:,:,kDown) in argument list of MOM_FLUXFORM
109        & MOM_VECINV subroutines (to help TAF). This fixes Pb of uninitialised
110        fVer?(kUp) in admom_fluxform with non-lin free-surf or bottom control.
111    
112    checkpoint63k (2012/03/17)
113    o model/src:
114       - selectAddFluid (ALLOW_ADDFLUID): add missing term in horizontal momentum
115         flux-form (mom_fluxform.F) and vertical momentum (calc_gw.F) equations.
116       - SOLVE_DIAGONAL: switch default to use adjoinable & vectorized version
117         (#undef SOLVE_DIAGONAL_LOWMEMORY); update output of exp. front_relax.bvp.
118    o model/src: solve_*diagonal.F
119       - replace division with multiplication by inverse (similar to original version)
120         update output of AD exp. global_ocean.90x40x15.
121       - fix pkg/gmredi/gmredi_calc_psi_bvp.F & pkg/ggl90/ggl90_calc.F
122         to enable the use of the vectorized & differentiable solve_tridiagonal.F
123       - test exp. global_ocean.90x40x15/input_ad: switch to advection scheme 20 for
124         vertical advection (to get solve_tridiagonal tested in AD mode).
125    o pkg/seaice: ECCO-CLIVAR merge:
126      1. seaice AREA relaxation
127         * CPP option: SEAICE_ALLOW_AREA_RELAXATION
128         * runtime flag: SEAICE_tauAreaObsRelax
129      2. modified global mean cost imbalance code: CPP option
130          ALLOW_SSH_GLOBMEAN_COST_CONTRIBUTION
131  o another iteration on solve_*diagonal.F  o another iteration on solve_*diagonal.F
132    Make choices independent of AUTODIFF     Make choices independent of AUTODIFF
133    Default is now the adjoinable vectorized version     Default will be the adjoinable vectorized version.
134    Alternative choices are:     Alternative choices are:
135    * still adjoinable but lower memory (k as inner-most loop)     * non-adjoinable original version with low memory footprint:
136    SOLVE_DIAGONAL_KINNER       #define SOLVE_DIAGONAL_LOWMEMORY
137    * non-adjoinable legacy version with low memory footprint     * still adjoinable but does not vectorize (k as inner-most loop):
138    SOLVE_DIAGONAL_LOWMEMORY       #define SOLVE_DIAGONAL_KINNER (keeping SOLVE_DIAGONAL_LOWMEMORY undef)
