4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/bbl:
8      - fix call to FIND_RHO_2D in bbl_calc_rho.F (case multi-tiles per proc);
9        update global_with_exf output.yearly.txt file.
10    o pkg/cal:
11      - start to clean-up cal_set.F ; fix for the case where baseTime is non-zero.
12      - remove 2 unsused and very short (1 line only) functions ;
13      - remove unsused subroutines from AD-Diff list.
14    o model/src:
15      - start to implement clean wait to stop in initialization S/R (config_check.F,
16         packages_check.F and pkg/obcs/obcs_check.F + pkg/mypackage)
17    o folowing PRINT_MESSAGE changes:
18      - remove reminder multiple print to the same file (STDOUT) when multi-threads.
19    o pkg/bbl:
20      - modification so it can work with z*
21      - replace deltaT with dTtracerLev(k) for asynchronous time stepping
22      - global_with_exf/input.yearly verification; changes output.yearly.txt
23    o eesupp/src:
24      - PRINT_MESSAGE: use OpenMP critical instruction (similar to PRINT_ERROR);
25        writing to unit 0 (if unit=errorMessageUnit) extended to the case myThid=1
26      - CHECK_THREADS: specific code if using OpenMP threading: improve checking of
27        # of threads across processors (e.g., different env OMP_NUM_THREADS setting)
28      - improve special preliminary call to EESET_PARMS (if eedata is read 2 times).
29      - when using MPI, always set usingMPI=T ; set default accordingly and stop
30        if not consistent.
31      - ALL_PROC_DIE: add a BARRIER after MPI_FINALIZE call ; skip this when thread
32        argument is zero (in case called within single-thread section).
33    o pkg/fizhi:
34        clean-up turbulence cold-start switch: decided in fizhi_init_vars.F, stored
35        in common bloc (fizhi_coms.h) and then passed as argument up to S/R TURBIO.
36    o pkg/exch2:
37      - add argument "updateCorners" to S/R exch2_get_uv_bounds (enable to
38        activate EXCH_IGNORE_CORNERS in vector EXCH S/R).
39      - switch 1rst EXCH call to IGNORE_CORNERS (instead of UPDATE_CORNERS)
40        but keep the 2nd with UPDATE_CORNERS: this prevents overwriting good data
41        with bad ones coming from a not-yet-updated halo.
42        This should fix the problem when sNx <> sNy and GCD(sNx,sNy) < 2*Olx.
43    o pkg/frazil:
44        move FrzForcT diag from frazil_diagnostics_state.F to frazil_calc_rhs.F
45        http://mitgcm.org/pipermail/mitgcm-devel/2012-March/005384.html
46    o model/src/config_check.F: add a check for OLx>sNx/OLy>sNy
47    o verification/lab_sea
48      * #undef SEAICE_EXCLUDE_FOR_EXACT_AD_TESTING
49      * #define ALLOW_SST_CONTROL & ALLOW_SST_CONTROL
50      * nTimeSteps 3 -> 4
51      * changed reference output accordingly
52    o pkg/ctrl:
53      * fix ctrl_get_gen for xx_sst, xx_sss
54    o pkg/fizhi:
55      - fix 2 calls to S/R GRD2MSC (argument igrd) in update_earth_exports.F
56        update results of exp. fizhi-cs-32x32x40 (fail with only 6 digits for cg2d)
57      - by default, use new version of S/R GETPWHERE (#define TRY_NEW_GETPWHERE);
58        fix few out-of-bounds indices in referencing vars (initialise igrd to 1);
59        clean-up fizhi_turb.F (remove unused & uninitialised qdiaglsm array).
60    o pkg/gmredi:
61      - add diagnostic of Redi (main diagnonal) vertical diffusive flux of Temp
62    o pkg/fizhi:
63      - fix few initialisation and multi-tile Pb: aqualev & gridalt now pass the
64        (old)aces open64 tuv test.
65    o pkg/icefront: fix bug and reorder loop in icefront_init_varia.F
66    o pkg/mom_vecinv:
67      - fix 1 loop range in mom_vecinv.F to be like all the other loops which
68        set/update gu,gv/Diss (fix Pb of uninitialised fVerUkp in admom_vecinv
69        with non-lin free-surf).
70    o model/src: move k-loop outside of i/j-loops when (re-)computing R_low
71      in ini/update_masks_etc.F in order to avoid -O3 optimization problems with
72      some compilers (gfortran 4.6.0 on MacOS)
73    o momentum:
74      - separate fVer?(:,:,kUp) & fVer?(:,:,kDown) in argument list of MOM_FLUXFORM
75        & MOM_VECINV subroutines (to help TAF). This fixes Pb of uninitialised
76        fVer?(kUp) in admom_fluxform with non-lin free-surf or bottom control.
77    
78    checkpoint63k (2012/03/17)
79    o model/src:
80       - selectAddFluid (ALLOW_ADDFLUID): add missing term in horizontal momentum
81         flux-form (mom_fluxform.F) and vertical momentum (calc_gw.F) equations.
82       - SOLVE_DIAGONAL: switch default to use adjoinable & vectorized version
83         (#undef SOLVE_DIAGONAL_LOWMEMORY); update output of exp. front_relax.bvp.
84    o model/src: solve_*diagonal.F
85       - replace division with multiplication by inverse (similar to original version)
86         update output of AD exp. global_ocean.90x40x15.
87       - fix pkg/gmredi/gmredi_calc_psi_bvp.F & pkg/ggl90/ggl90_calc.F
88         to enable the use of the vectorized & differentiable solve_tridiagonal.F
89       - test exp. global_ocean.90x40x15/input_ad: switch to advection scheme 20 for
90         vertical advection (to get solve_tridiagonal tested in AD mode).
91    o pkg/seaice: ECCO-CLIVAR merge:
92      1. seaice AREA relaxation
93         * CPP option: SEAICE_ALLOW_AREA_RELAXATION
94         * runtime flag: SEAICE_tauAreaObsRelax
95      2. modified global mean cost imbalance code: CPP option
96          ALLOW_SSH_GLOBMEAN_COST_CONTRIBUTION
97    o another iteration on solve_*diagonal.F
98       Make choices independent of AUTODIFF
99       Default will be the adjoinable vectorized version.
100       Alternative choices are:
101       * non-adjoinable original version with low memory footprint:
102         #define SOLVE_DIAGONAL_LOWMEMORY
103       * still adjoinable but does not vectorize (k as inner-most loop):
104         #define SOLVE_DIAGONAL_KINNER (keeping SOLVE_DIAGONAL_LOWMEMORY undef)
105    o testreport
106     - add option to use a home made wrapper around "make"
107     - remove MITGCM_IEEE env. variable (no longer active)
108    o pkg/shelfice
109     - improve computation of friction velocity for velocity dependent
110       exchange coefficients: include velocities into SHELFICEBoundaryLayer
111       block to average velocities vertically
112     - add TAF store directives for SHI_ALLOW_GAMMAFRICT
113    o Modify diagonal solvers, now three versions (upon request):
114      #ifndef SOLVE_DIAGONAL_AUTODIFF
115        1. default version (dating back a while ago)
116      #else /* def SOLVE_DIAGONAL_AUTODIFF */
117      # ifdef SOLVE_DIAGONAL_KINNER
118        2. adjoinable version with k-innermost loop (G. Forget)
119      # else
120        3. adjoinable vectorized version of 2.
121      # endif
122      #endif /* SOLVE_DIAGONAL_AUTODIFF */
123      All flags are currently set within routines, but could/should be moved to CPP-options.
124      Array bounds for 1. are as before, for 2.,3. cover the entire domain
125      (could be changed for 1. too).
126    o verification/lab_sea (fwd):
127      - update the 4 fwd lab_sea test experiment: no longer SEAICE_GROWTH_LEGACY,
128        use 7 categories (except hb87), new solve4temp params (except salt_plume),
129        constant salinity (=4) or variable salinity (salt_plume) done through
130        SItracer.
131    o pkg/seaice:
132      - rename parameters: SIsalFrac to SEAICE_saltFrac & SIsal0 to SEAICE_salt0;
133      - remove old parameters ( SEAICE_freeze, SEAICEturbFluxFormula, SEAICE_gamma_t,
134         SEAICE_gamma_t_frz, SEAICE_availHeatTaper & SEAICE_availHeatFracFrz)
135        from SEAICE_PARMS.h ; still need to fix seaice_cost_sst.F (broken when
136        SEAICE_freeze got retired) but already better than previously with
137        SEAICE_freeze=123456.7 deg.C;
138      - move setting of facOpenGrow/Melt from SEAICE_INIT_FIXED to SEAICE_READPARMS
139        (safer multi-threaded setting); always set SEAICEuseEVP;
140      - setting of ocean-ice turb. flux coeff: moved from SEAICE_CHECK to
141        SEAICE_READPARMS & SEAICE_INIT_FIXED (this fixes wrong summary report);
142        stop if multiple specifications for the same coeff; make sure default
143        SEAICE_mcPheePiston is compatible with drF(1) & deltaT.
144    o pkg/obcs:
145      - allow to switch to upwind 1rst order advection scheme for the advective
146        flux computation at the open-boundary; disabled for adjoint built.
147    o pkg/ptracers:
148      - rename PTRACERS_RESTART.h -> PTRACERS_START.h
149      - rename ptracers_fields_blocking_exchanges.F -> ptracers_fields_blocking_exch.F
150      - add parameter to decide when to start a tracer; use internal flag to
151        know which tracer to step-forward; switch this internal flag at the top
152        of forward_step.F (new S/R PTRACERS_SWITCH_ONOFF); for now, not enabled
153        for adjoint built.
154    o pkg/seaice:
155      - add SEAICE_SIZE.h anywhere in the code where SEAICE.h is included ;
156      - move MULTDIM declaration and setting from SEAICE.h to SEAICE_SIZE.h ;
157      - keep experiment offline_exf_seaice truly single category (set MULTDIM=1).
158  o pkg/ecco:  o pkg/ecco:
159    - fix writing of output file DiagnosCost_ClimSalt/Theta    - fix writing of output file DiagnosCost_ClimSalt/Theta
160      and DiagnosCost_DriftSalt/Theta (if multi-tiles per proc).      and DiagnosCost_DriftSalt/Theta (if multi-tiles per proc).
161  o pkg/seaice :  o pkg/seaice:
162    - add missing initialisation of COR_ICE array in dynsolver.F    - add missing initialisation of COR_ICE array in dynsolver.F
163    - merging SEAICE_MULTICATEGORY define and undef cases. Now the same code is    - merging SEAICE_MULTICATEGORY define and undef cases. Now the same code is
164      compiled either way, and is tested in all exps (multidim was only tested      compiled either way, and is tested in all exps (multidim was only tested
