5      ==============================      ==============================
6    
7    o eesupp:
8     - add new CPP option (DISCONNECTED_TILES) to disconnect tiles (no exchange
9       between tiles, just fill-in edges assuming locally periodic subdomain) and
10       add corresponding exchange subroutines (EXCH0);
11     - new CG-solver version (_EX0) for disconnected-tiles special case.
12    o model/src (CG-solvers):
13     - modify Single-Reduction version (CG2D_SR) in case cg2dMaxIters is reached
14       (similar final residual output and max-Iter number as with standard version);
15     - allows to store and use lowest-residual solution (standard & _SR versions);
16     - cleaning up (remove old, commented out code, LETS_MAKE_JAM ...).
17     - by default, also compile CG2D_SR version (define ALLOW_SRCG in CPP_OPTIONS.h)
18    o eesup/src:
19     - global_vec_sum.F cleaning: add a BARRIER ; update comments ; remove ndef
20       ALWAYS_USE_MPI (no longer needed after fixing usingMPI settings - March 2012)
21    o pkg/salt_plume added to lab_sea/input_ad.noseaicedyn
22    
23    checkpoint63m (2012/04/27)
24    o pkg/shelfice:
25     - account for partical cells in surface level below ice-shelf for hydrostatic
26       pressure calculion (set uniformFreeSurfLev to F); update isomip experiments.
27    o ad test experiments:
28     - update and rename to "ad_optfile.local" local AD-optfile specific to a
29       particular adjoint verification experiment (in verification/*/code_ad/)
30    o pkg/seaice & pkg/exf:
31     - Part two of ECCO-CLIVAR code merges.
32       Completes merge of seaice area relax. code.
33       Requires unified CPP option EXF_ALLOW_SEAICE_RELAX
34       to be set in EXF_OPTIONS.h since this pkg controls its I/O
35       (and avoids second CPP option in SEAICE_OPTIONS.h)
36     - change default value of costIceStart & costIceEnd to a valid date.
37     - add snowPrecip to HSNOW in seaice_growth
38    o pkg/ptracers:
39     - move ptracers summary and setup check into separated S/R ; add a check for
40       valid PTRACERS_Iter0 value (error+stop or just warning).
41    o pkg/cal (+ pkg/ecco):
42     - avoid calling a S/R with 2 times the same arg (FWD: unless both are only used
43       as input; and for AD, unless both are not differentiable (e.g., k index)).
44    o model/src:
45     - define internal flag "uniformFreeSurfLev" (=T when free-surface level-index
46       is everywhere k=1) to speed-up some calculations (by pass kSurf reference);
47       temporary set to usingZCoords value (to be changed to F when using shelfice).
48     - hydrostatic pressure: implement partial cell near the surface also for
49       Z-coordinates (for the case where uniformFreeSurfLev=F); replace test on
50       usingZCoords with test on uniformFreeSurfLev where needed (in NonHyd code).
51    o pkg/ctrl/ctrl_init.F:
52     - add a formal parameter to s/r ctrl_init_rec to print
53       xx_$(ctrl_valiable)_file for easier debugging
54     - move call of cal_* routines into the if-block where they are really
55       needed so that xx_$(ctrl_variable)_period can be 0 or -12 without having
56       to specify a startdate
57    o pkg/seaice:
58     - update comments in SEAICE_OPTIONS.h (+ similar update of lab_sea/code and
59       global_ocean.cs32x15/code versions).
60     - turn on seaice Multi-category (in data.seaice, SEAICE_multDim=7) for
61       verification experiment global_ocean.cs32x15.seaice and update results.
62    o pkg/exf:
63     - new S/R EXF_GETFIELD_START to return starting-time of a forcing field
64       (according to useExfYearlyFields).
65    o pkg/cal:
66     - move calendar setting & summary (previously in cal_readparams.F) into new
67       S/R CAL_INIT_FIXED to be called later in the initialisation process, once
68       length of the simulation is set (after SET_PARMS call); This is an attempt
69       to fix Pb when, e.g.: pkg/longstep, modifies the length of the run.
70     - For safety: keep a record of pkg/cal parameter settings status
71               to allow to STOP if one pkg/cal S/R is called too early.
72     - add a stop in all basic pkg/cal subroutines if called before setting is done.
73     - modify cal_getdate.F: stop when nothing was returned;
74       if called with myIter=-1, simply retrun modelBaseDate (1,2 = startDate_1,_2);
75       this allows to remove "cal.h" from seaice_read_parms.F & init_mnc_vars.F.
76    
77    checkpoint63l (2012/04/04)
78    o pkg/bbl:
79      - fix call to FIND_RHO_2D in bbl_calc_rho.F (case multi-tiles per proc);
80        update global_with_exf output.yearly.txt file.
81    o pkg/cal:
82      - start to clean-up cal_set.F ; fix for the case where baseTime is non-zero.
83      - remove 2 unsused and very short (1 line only) functions ;
84      - remove unsused subroutines from AD-Diff list.
85    o model/src:
86      - start to implement clean wait to stop in initialization S/R (config_check.F,
87         packages_check.F, ini_parms.F and pkg/obcs/obcs_check.F + pkg/mypackage)
88    o folowing PRINT_MESSAGE changes:
89      - remove reminder multiple print to the same file (STDOUT) when multi-threads.
90    o pkg/bbl:
91      - modification so it can work with z*
92      - replace deltaT with dTtracerLev(k) for asynchronous time stepping
93      - global_with_exf/input.yearly verification; changes output.yearly.txt
94    o eesupp/src:
95      - PRINT_MESSAGE: use OpenMP critical instruction (similar to PRINT_ERROR);
96        writing to unit 0 (if unit=errorMessageUnit) extended to the case myThid=1
97      - CHECK_THREADS: specific code if using OpenMP threading: improve checking of
98        # of threads across processors (e.g., different env OMP_NUM_THREADS setting)
99      - improve special preliminary call to EESET_PARMS (if eedata is read 2 times).
100      - when using MPI, always set usingMPI=T ; set default accordingly and stop
101        if not consistent.
102      - ALL_PROC_DIE: add a BARRIER after MPI_FINALIZE call ; skip this when thread
103        argument is zero (in case called within single-thread section).
104    o pkg/fizhi:
105        clean-up turbulence cold-start switch: decided in fizhi_init_vars.F, stored
106        in common bloc (fizhi_coms.h) and then passed as argument up to S/R TURBIO.
107    o pkg/exch2:
108      - add argument "updateCorners" to S/R exch2_get_uv_bounds (enable to
109        activate EXCH_IGNORE_CORNERS in vector EXCH S/R).
110      - switch 1rst EXCH call to IGNORE_CORNERS (instead of UPDATE_CORNERS)
111        but keep the 2nd with UPDATE_CORNERS: this prevents overwriting good data
112        with bad ones coming from a not-yet-updated halo.
113        This should fix the problem when sNx <> sNy and GCD(sNx,sNy) < 2*Olx.
114    o pkg/frazil:
115        move FrzForcT diag from frazil_diagnostics_state.F to frazil_calc_rhs.F
116        http://mitgcm.org/pipermail/mitgcm-devel/2012-March/005384.html
117    o model/src/config_check.F: add a check for OLx>sNx/OLy>sNy
118    o verification/lab_sea
119      * #undef SEAICE_EXCLUDE_FOR_EXACT_AD_TESTING
120      * #define ALLOW_SST_CONTROL & ALLOW_SST_CONTROL
121      * nTimeSteps 3 -> 4
122      * changed reference output accordingly
123    o pkg/ctrl:
124      * fix ctrl_get_gen for xx_sst, xx_sss
125    o pkg/fizhi:
126      - fix 2 calls to S/R GRD2MSC (argument igrd) in update_earth_exports.F
127        update results of exp. fizhi-cs-32x32x40 (fail with only 6 digits for cg2d)
128      - by default, use new version of S/R GETPWHERE (#define TRY_NEW_GETPWHERE);
129        fix few out-of-bounds indices in referencing vars (initialise igrd to 1);
130        clean-up fizhi_turb.F (remove unused & uninitialised qdiaglsm array).
131    o pkg/gmredi:
132      - add diagnostic of Redi (main diagnonal) vertical diffusive flux of Temp
133    o pkg/fizhi:
134      - fix few initialisation and multi-tile Pb: aqualev & gridalt now pass the
135        (old)aces open64 tuv test.
136  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
137  o model/src: move k-loop outside of i/j-loops when (re-)computing R_low  o pkg/mom_vecinv:
138    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
139        set/update gu,gv/Diss (fix Pb of uninitialised fVerUkp in admom_vecinv
140        with non-lin free-surf).
141    o model/src: move k-loop outside of i/j-loops when (re-)computing R_low
142      in ini/update_masks_etc.F in order to avoid -O3 optimization problems with
143    some compilers (gfortran 4.6.0 on MacOS)    some compilers (gfortran 4.6.0 on MacOS)
144  o momentum:  o momentum:
145    - separate fVer?(:,:,kUp) & fVer?(:,:,kDown) in argument list of MOM_FLUXFORM    - separate fVer?(:,:,kUp) & fVer?(:,:,kDown) in argument list of MOM_FLUXFORM
