5      ==============================      ==============================
6    
7    o pkg/seaice & pkg/exf:
8       Part two of ECCO-CLIVAR code merges.
9       Completes merge of seaice area relax. code.
10       Requires unified CPP option EXF_ALLOW_SEAICE_RELAX
11       to be set in EXF_OPTIONS.h since this pkg controls its I/O
12       (and avoids second CPP option in SEAICE_OPTIONS.h)
13    o pkg/ptracers:
14     - move ptracers summary and setup check into separated S/R ; add a check for
15       valid PTRACERS_Iter0 value (error+stop or just warning).
16    o pkg/cal (+ pkg/ecco):
17     - avoid calling a S/R with 2 times the same arg (FWD: unless both are only used
18       as input; and for AD, unless both are not differentiable (e.g., k index)).
19    o model/src:
20     - define internal flag "uniformFreeSurfLev" (=T when free-surface level-index
21       is everywhere k=1) to speed-up some calculations (by pass kSurf reference);
22       temporary set to usingZCoords value (to be changed to F when using shelfice).
23     - hydrostatic pressure: implement partial cell near the surface also for
24       Z-coordinates (for the case where uniformFreeSurfLev=F); replace test on
25       usingZCoords with test on uniformFreeSurfLev where needed (in NonHyd code).
26    o pkg/ctrl/ctrl_init.F:
27     - add a formal parameter to s/r ctrl_init_rec to print
28       xx_$(ctrl_valiable)_file for easier debugging
29     - move call of cal_* routines into the if-block where they are really
30       needed so that xx_$(ctrl_variable)_period can be 0 or -12 without having
31       to specify a startdate
32    o pkg/seaice:
33     - update comments in SEAICE_OPTIONS.h (+ similar update of lab_sea/code and
34       global_ocean.cs32x15/code versions).
35     - turn on seaice Multi-category (in data.seaice, SEAICE_multDim=7) for
36       verification experiment global_ocean.cs32x15.seaice and update results.
37    o pkg/exf:
38     - new S/R EXF_GETFIELD_START to return starting-time of a forcing field
39       (according to useExfYearlyFields).
40    o pkg/cal:
41     - move calendar setting & summary (previously in cal_readparams.F) into new
42       S/R CAL_INIT_FIXED to be called later in the initialisation process, once
43       length of the simulation is set (after SET_PARMS call); This is an attempt
44       to fix Pb when, e.g.: pkg/longstep, modifies the length of the run.
45     - For safety: keep a record of pkg/cal parameter settings status
46               to allow to STOP if one pkg/cal S/R is called too early.
47     - add a stop in all basic pkg/cal subroutines if called before setting is done.
48     - modify cal_getdate.F: stop when nothing was returned;
49       if called with myIter=-1, simply retrun modelBaseDate (1,2 = startDate_1,_2);
50       this allows to remove "cal.h" from seaice_read_parms.F & init_mnc_vars.F.
51    
52    checkpoint63l (2012/04/04)
53    o pkg/bbl:
54      - fix call to FIND_RHO_2D in bbl_calc_rho.F (case multi-tiles per proc);
55        update global_with_exf output.yearly.txt file.
56    o pkg/cal:
57      - start to clean-up cal_set.F ; fix for the case where baseTime is non-zero.
58      - remove 2 unsused and very short (1 line only) functions ;
59      - remove unsused subroutines from AD-Diff list.
60    o model/src:
61      - start to implement clean wait to stop in initialization S/R (config_check.F,
62         packages_check.F, ini_parms.F and pkg/obcs/obcs_check.F + pkg/mypackage)
63    o folowing PRINT_MESSAGE changes:
64      - remove reminder multiple print to the same file (STDOUT) when multi-threads.
65    o pkg/bbl:
66      - modification so it can work with z*
67      - replace deltaT with dTtracerLev(k) for asynchronous time stepping
68      - global_with_exf/input.yearly verification; changes output.yearly.txt
69    o eesupp/src:
70      - PRINT_MESSAGE: use OpenMP critical instruction (similar to PRINT_ERROR);
71        writing to unit 0 (if unit=errorMessageUnit) extended to the case myThid=1
72      - CHECK_THREADS: specific code if using OpenMP threading: improve checking of
73        # of threads across processors (e.g., different env OMP_NUM_THREADS setting)
74      - improve special preliminary call to EESET_PARMS (if eedata is read 2 times).
75      - when using MPI, always set usingMPI=T ; set default accordingly and stop
76        if not consistent.
77      - ALL_PROC_DIE: add a BARRIER after MPI_FINALIZE call ; skip this when thread
78        argument is zero (in case called within single-thread section).
79    o pkg/fizhi:
80        clean-up turbulence cold-start switch: decided in fizhi_init_vars.F, stored
81        in common bloc (fizhi_coms.h) and then passed as argument up to S/R TURBIO.
82    o pkg/exch2:
83      - add argument "updateCorners" to S/R exch2_get_uv_bounds (enable to
84        activate EXCH_IGNORE_CORNERS in vector EXCH S/R).
85      - switch 1rst EXCH call to IGNORE_CORNERS (instead of UPDATE_CORNERS)
86        but keep the 2nd with UPDATE_CORNERS: this prevents overwriting good data
87        with bad ones coming from a not-yet-updated halo.
88        This should fix the problem when sNx <> sNy and GCD(sNx,sNy) < 2*Olx.
89    o pkg/frazil:
90        move FrzForcT diag from frazil_diagnostics_state.F to frazil_calc_rhs.F
91        http://mitgcm.org/pipermail/mitgcm-devel/2012-March/005384.html
92    o model/src/config_check.F: add a check for OLx>sNx/OLy>sNy
93    o verification/lab_sea
94      * #undef SEAICE_EXCLUDE_FOR_EXACT_AD_TESTING
95      * #define ALLOW_SST_CONTROL & ALLOW_SST_CONTROL
96      * nTimeSteps 3 -> 4
97      * changed reference output accordingly
98    o pkg/ctrl:
99      * fix ctrl_get_gen for xx_sst, xx_sss
100    o pkg/fizhi:
101      - fix 2 calls to S/R GRD2MSC (argument igrd) in update_earth_exports.F
102        update results of exp. fizhi-cs-32x32x40 (fail with only 6 digits for cg2d)
103      - by default, use new version of S/R GETPWHERE (#define TRY_NEW_GETPWHERE);
104        fix few out-of-bounds indices in referencing vars (initialise igrd to 1);
105        clean-up fizhi_turb.F (remove unused & uninitialised qdiaglsm array).
106    o pkg/gmredi:
107      - add diagnostic of Redi (main diagnonal) vertical diffusive flux of Temp
108    o pkg/fizhi:
109      - fix few initialisation and multi-tile Pb: aqualev & gridalt now pass the
110        (old)aces open64 tuv test.
111  o pkg/icefront: fix bug and reorder loop in icefront_init_varia.F  o pkg/icefront: fix bug and reorder loop in icefront_init_varia.F
112  o model/src: move k-loop outside of i/j-loops when (re-)computing R_low  o pkg/mom_vecinv:
113    in ini/update_masks_etc.F in order to avoid -O3 optimization problems with    - fix 1 loop range in mom_vecinv.F to be like all the other loops which
114        set/update gu,gv/Diss (fix Pb of uninitialised fVerUkp in admom_vecinv
115        with non-lin free-surf).
116    o model/src: move k-loop outside of i/j-loops when (re-)computing R_low
117      in ini/update_masks_etc.F in order to avoid -O3 optimization problems with
118    some compilers (gfortran 4.6.0 on MacOS)    some compilers (gfortran 4.6.0 on MacOS)
119  o momentum:  o momentum:
120    - separate fVer?(:,:,kUp) & fVer?(:,:,kDown) in argument list of MOM_FLUXFORM    - separate fVer?(:,:,kUp) & fVer?(:,:,kDown) in argument list of MOM_FLUXFORM
