5      ==============================      ==============================
6    
7    o verification/cfc_example:
8      - update file "data" with more standard choice (default rotationPeriod,
9        exactConserv=T, reduce ivdc_kappa to 10, remove multiDimAdvection=F,
10        set deltaTFreeSurf to deltaTtracer) and update the output.
11    o pkg/layers:
12      - fix bolus part so that it compiles with #undef GM_BOLUS_ADVEC;
13      - ensure that "layers_bolus" is switched to False when useGMRedi=False.
14    o verification/offline_exf_seaice:
15      - set all {field}period to zero for constant-in-time forcing (not tested
16        anywhere else).
17    o verification/offline_exf_seaice:
18      - dyn_lsr  : use pkg/seaice S/R (instead of pkg/thsice) to advect sea-ice;
19      - dyn_jfnk : use pkg/thsice S/R (instead of pkg/seaice) to advect sea-ice.
20    o model/src:
21      - implement Finite-Volume method for (hydrostatic) presure gradient
22        from S.-J. Lin (QJRMS 1997), for atmosphere using sigma-coordinate.
23    o pkg/seaice: implement EVP* by Lemieux et al. (2012).
24      - In order to be compatible with the default EVP code, this requires changing
25        the EVP code around a little; and because any small change immediately
26        breaks the lab_sea.hb87 verification experiment, the reference output is
27        updated two times (each time the remaining aggrement was only 2 digits):
28        - after replacing 1/dt by 1*recip_dt with a precomputed recip_dt
29        - after replacing 1/(1+0.5*dt/tau) by a/(a+1), with a=2*tau/dt
30        The adjoint test lab_sea.evp also needed to be updated.
31      - Turn on EVP* by setting SEAICE_deltaTevp as before, and setting
32        SEAICEuseEVPstar=.true.; for EVP* SEAICE_deltaTevp does not need to be
33        a factor of SEAICE_deltaTdyn, and you can set the number of EVP steps
34        explicitly with SEAICEnEVPstarSteps (thereby overriding the default of
35        INT(SEAICE_deltaTdyn/SEAICE_deltaTevp)). Controlling EVP* is deliberately
36        kept obscure, because I need to test it a little more.
37    o pkg/cheapaml:
38      - fix few incorrect type (_RL/_RS) in subroutine calls.
39    o pkg/seaice:
40      - new S/R SEAICE_MAP_RS2VEC (similar to SEAICE_MAP2VEC) to map _RS arrays
41        to _RL vector; this fixes JFNK code when compiling with "-use_r4" option.
42    o model/src:
43      - add a warning if using select_rStar=2 with nonlinFreeSurf <> 4;
44        change (in input_ad*/data) select_rStar from 2 to 1 for AD verification
45        experiments global_ocean.cs32x15 & tutorial_tracer_adjsens (+ update output)
46    o pkg/cheapaml:
47      - replace "273.1 _d 0" by celsius2K in pkg/cheapaml/cheapaml.F and
48        update output of experiment cheapAML_box.
49      - store in CHEAPAML.h coeffs ssq[0:2] for saturation specific humidity,
50        and set them only in one place (cheapaml_readparms.F).
51      - replace "273.16 _d 0" by celsius2K & replace "3.14159 _d 0" by constant "PI"
52      - remove re-setting of main-model parameter "celsius2K" (in cheapaml_readparms)
53        and re-setting of cheapAML params "lath" & "p0" (in cheapaml_init_varia).
54    o model/src/the_main_loop.F:
55      - fix revision 129 : need both ALLOW_ECCO and ALLOW_ECCO_EVOLUTION.
56    o pkg/seaice:
57      - remove legacy branch code.
58      - retire SEAICE_GROWTH_LEGACY and SEAICE_CAP_HEFF accordingly.
59    o verification/*/code*/SEAICE_OPTIONS.h:
60      - remove documentation for retired CPP flags (SEAICE_GROWTH_LEGACY,
61        SEAICE_CAP_HEFF).
62    o pkg/cheapaml:
63      - use standard routine (S/R GET_PERIODIC_INTERVAL) to decide when it is time
64        to load new forcing fields.
65      - add missing "_d 0" where it's needed; + some editing (improve indentation).
66      - remove switch to "-r8" compiler option (no longer needed) in verification
67        cheapAML_box, keep same output (small trucation error differences).
68    o verification/offline_exf_seaice:
69      - add thermodynamics only test.
70    o verification/cheapAML_box:
71      - split the domain in 8 (2x4) tiles; add MPI and multi-threaded test;
72        keep same output (same 14 digits for cg2d).
73      - switch on "-r8" compiler option (some numerical values are missing
74        the "_d 0") and update output (only 6 digits for cg2d were preserved).
75    
76    checkpoint64b (2012/12/24)
77    o pkg/cheapaml:
78      - remove un-used variables (Qnet,EmPmR) from pickup files.
79      - store tendency of advected variables into cheapaml pickup file
80        and fix the AB-2 restart.
81    o verification/offline_exf_seaice and lab_sea adjoint:
82      - switch to new code (#undef SEAICE_GROWTH_LEGACY).
83      - switch to 4 time steps in offline, consistent with lab_sea.
84      - match parameters from SEAICE_GROWTH_LEGACY branch in data.seaice.
85      - update results after change of experiment seaice.
86    o pkg/seaice:
87      - remove option SEAICE_MULTICATEGORY; has been replaced with run-time
88        parameter SEAICE_multDim. Issue a warning if SEAICE_MULTICATEGORY is
89        still defined since SEAICE_multDim needs to be set to MULTDIM value (from
90        SEAICE_SIZE.h) to recover previous #define SEAICE_MULTICATEGORY default.
91    o model/src:
92      - add run-time parameter to select CG2D solver minimum-residual solution
93        (in case of a poor convergence).
94    o pkg/seaice/seaice_lsr.F
95      - move calculation of matrix coefficients into new
96        S/R SEAICE_CALC_LSR_COEFFS; for now this routine remains in the same
97        file; the main purpose of this change is to be able to reuse the code
98        in S/R SEAICE_PRECONDITIONER
99      - modify the computation of the residual so that the mass of sea-ice
100        is not used twice; this simplifies the calculations, but since
101        the residual is never used except when LSR_mixIniGuess.ge.4---and this is
102        not tested in testreport---this does not affect the testreport results.
103    o verification/seaice_obcs:
104      - disable SEAICE_GROWTH_LEGACY; reset input files to match those of
105        verification/lab_sea/input.salt_plume; changes results/output.txt*
106    o model/src:
107      - adapt quasi-hydrostatic formulation to work with p or p* coordinate.
