5      ==============================      ==============================
6    
7  o pkg/ggl90: fix computation of control volumes for the case of  o pkg/cheapaml:
8      - use standard routine (S/R GET_PERIODIC_INTERVAL) to decide when it is time
9        to load new forcing fields.
10      - add missing "_d 0" where it's needed; + some editing (improve indentation).
11      - remove switch to "-r8" compiler option (no longer needed) in verification
12        cheapAML_box, keep same output (small trucation error differences).
13    o verification/offline_exf_seaice:
14      - add thermodynamics only test.
15    o verification/cheapAML_box:
16      - split the domain in 8 (2x4) tiles; add MPI and multi-threaded test;
17        keep same output (same 14 digits for cg2d).
18      - switch on "-r8" compiler option (some numerical values are missing
19        the "_d 0") and update output (only 6 digits for cg2d were preserved).
20    
21    checkpoint64b (2012/12/24)
22    o pkg/cheapaml:
23      - remove un-used variables (Qnet,EmPmR) from pickup files.
24      - store tendency of advected variables into cheapaml pickup file
25        and fix the AB-2 restart.
26    o verification/offline_exf_seaice and lab_sea adjoint:
27      - switch to new code (#undef SEAICE_GROWTH_LEGACY).
28      - switch to 4 time steps in offline, consistent with lab_sea.
29      - match parameters from SEAICE_GROWTH_LEGACY branch in data.seaice.
30      - update results after change of experiment seaice.
31    o pkg/seaice:
32      - remove option SEAICE_MULTICATEGORY; has been replaced with run-time
33        parameter SEAICE_multDim. Issue a warning if SEAICE_MULTICATEGORY is
34        still defined since SEAICE_multDim needs to be set to MULTDIM value (from
35        SEAICE_SIZE.h) to recover previous #define SEAICE_MULTICATEGORY default.
36    o model/src:
37      - add run-time parameter to select CG2D solver minimum-residual solution
38        (in case of a poor convergence).
39    o pkg/seaice/seaice_lsr.F
40      - move calculation of matrix coefficients into new
41        S/R SEAICE_CALC_LSR_COEFFS; for now this routine remains in the same
42        file; the main purpose of this change is to be able to reuse the code
43        in S/R SEAICE_PRECONDITIONER
44      - modify the computation of the residual so that the mass of sea-ice
45        is not used twice; this simplifies the calculations, but since
46        the residual is never used except when LSR_mixIniGuess.ge.4---and this is
47        not tested in testreport---this does not affect the testreport results.
48    o verification/seaice_obcs:
49      - disable SEAICE_GROWTH_LEGACY; reset input files to match those of
50        verification/lab_sea/input.salt_plume; changes results/output.txt*
51    o model/src:
52      - adapt quasi-hydrostatic formulation to work with p or p* coordinate.
53    o pkg/seaice:
54      - improve description of parameters in seaice_fgmres.F and start
55        cleaning up the code
56      - change name of SCALPROD to SEAICE_SCALPROD and modify meaning of
57        second argument
58      - add a metric based on grid cell area to SEAICE_SCALPROD; update
59        results of offline_exf_seaice.dyn_jfnk
60      - compute initial residual norm in seaice_jfnk based on SEAICE_SCALPROD
61    o pkg/aim_v23:
62      - fix an other bug in dissipation heating (grid-cell area was missing).
63    o model/src + pkg/seaice:
64      - add global (multi-tile) linear solver for pair of tri-diagonal system
65        along X and Y lines, respectively for U and V component.
66        Note: 1) MPI and cube-exchange not yet coded.
67            2) probably not accurate for poorly conditioned / large size problem.
68      - add option for SEAICE_LSR to use global (multi-tile) tri-diagonal solver;
69        default: not compiled and not used.
70    o pkg/seaice:
71      - first attempt at a multi-threaded fgmres solver for the JFNK solver:
72        introduce bi/bj loops and use global_sum_tile_rl instead of
73        mpi_allreduce in seaice_fgmres.F
74      - improve diagnostics output for fgmres solver (seaice_fgmres.F)
75      - replace a few unnecessary goto statements by if-blocks  (seaice_fgmres.F)
76      - add a verification experiment for JFNK in offline_exf_seaice
77    o verification:
78      - change (for now, only fwd test) offline_exf_seaice experiment:
79        use a re-entrant channel with idealized coastline (trapezoidal shape)
80        at southern boundary to explore seaice dynamics and thermodynamics
81        with simple forcing. Main set-up has dynamics+thermo and SST relaxation;
82        secondary test (input.thsice) use thermodynamics only with SST relaxation.
83      - add seaice-dynamics only secondary test using LSR and pkg/thsice advection.
84    o pkg/exf:
85      - disable "sstExtrapol" when Nr=1
86    o verification:
87      - add new experiment "cheapAML_box" (simple 1 layer set-up from Bruno Deremble)
88        to test pkg/cheapaml.
89    o pkg/aim_v23 & pkg/shap_filt:
90      - fix dissipation heating (erroneous gravity multiplication factor).
91    o pkg/seaice:
92      - remove unused field pressPre from jfnk solver
93      - rename two subroutines in seaice_preconditioner.F
94    o eesupp/src:
95       - S/R MDSFINDUNIT avoids reserved unit numbers (scrUnit1, eeDataUnit ...)
96    o pkg/seaice/seaice_preconditioner.F: fix preconditioner once again
97       - remove wrong parts of the rhs and the lhs (were in there
98         because I did not understand the concept of this preconditioner)
99       - add an exchange between u- and v-sweep. This increases communication
100         by a factor of two but improves the convergence of jfnk. Ideally,
101         one would like the u- and v-sweep to be independent. So far within
102         undocumented ifdefs
103       - reorganize the extra computations for printing the residuals
104    o tools/genmake2:
105      - comment out the "mpif.h" include in NetCDF test programm (for MPI built)
106        since it's not necessary (and was preventing to use MNC in some cases).
107    
108    checkpoint64a (2012/11/16)
109    o pkg/autodiff:
110      - improve pkg-internal logical parameter switch (inAd/inFwd mode) so that
111        autodiff_readparms.F no longer depends on calling order (within
112        packages_readparms.F) and no longer requires to include ${PKG}_PARMS.h):
113        rename param turnFreeDriftInAdMode to SEAICEuseFREEDRIFTswitchInAd
114        and change param SEAICEuseDYNAMICSinAdMode to SEAICEuseDYNAMICSswitchInAd.
115    o pkg/obcs:
116      - adding tidal velocity forcing capability to obcs
117        for usage example, see verification/seaice_obcs/input.tides
118    o pkg/seaice:
119      - turn the LSR-relaxation parameters WFAU/V into runtime parameters
120        SEAICE_LSRrelaxU/V
121      - introduce runtime parameter SEAICEetaZmethod (=0 by default)
122    o pkg/aim_v23:
123      - implement heating from friction (bottom friction and stratospheric drag).
124    o pkg/shap_filt:
125      - fix diagnostic "SHAP_dKE" (was 2 time smaller); implement heating from
126        dissipation but only for Shap_funct=2, active when addFrictionHeating=T.
127    o model/src:
128      - move AddMass common block from DYNVARS.h to FFIELDS.h; allow to read-in
129        time-constant addMass field from file (addMassFile);
130      - support for heating due to friction (and Kinetic Energy dissipation):
131        add option, run-time switch and 3-D field array + support code ; each pkg
132        or S/R can add heating contribution (if there is a sink of KE); the sum is
133        accounted for as a Temperature tendency term (EXTERNAL_FORCING_T).
134    o pkg/seaice:
135      - complete merge of ITD code into seaice_growth.F
136        from MITgcm_contrib/torge/itd/code/
137        no verification so far, but Torge Martin tested
138        "1-D test case and Beaufort set up;
139        deliver okay results after 1 model year."
140      - complete merge of SEAICE_SIZE.h into all relevant routines
141      - move computation of eta at Z-points into calc_viscosities
142        + introduce global field etaZ
143        + add different methods for computing etaZ, for now the old
144          method (simple averages of eta to Z-points) is hardwired
145        + replace etaMeanZ by etaZ in seaice_lsr, seaice_calc_residual,
146          seaice_preconditioner
147      - simplify computations for SEAICE_ZETA_SMOOTHREG
148      - seaice_preconditioner:
149        + replace one remaining press by pressLoc (mistake)
150        + adjust printing of residuals
151      - improve I/O of diagnostics of JFNK in seaice_jfnk.F:
152        + add (SEAICE.h) and rename some counters (initiliased in
153          seaice_init_fixed.F)
154        + add _BEGIN/END_MASTER (myThid)  around print statements
155        + print total number of iterations and failures over SEAICE_monFreq
156          interval to STDOUT
157      - move control over output-messages by fgmres to seaice_jfnk to save
158        some operations
159      - move resetting initial guess for fgmres outside of seaice_fgmres_driver
160        in order to make restarts with sol .ne. zero (fgmres with restarts)
161        (seaice_jfnk.F, seaice_fgmres.F)
162      - seaice_calc_l/rhs.F: replace maskW/S by maskInW/S; this fixes
163        a serious convergence problem when open boundaries are involved
164    o pkg/ggl90: fix computation of control volumes for the case of
165    ALLOW_GGL90_HORIZDIFF (probably not used very often): move control volumes    ALLOW_GGL90_HORIZDIFF (probably not used very often): move control volumes
