7    checkpoint63k (2012/03/17)
8    o model/src:
9       - selectAddFluid (ALLOW_ADDFLUID): add missing term in horizontal momentum
10         flux-form (mom_fluxform.F) and vertical momentum (calc_gw.F) equations.
11       - SOLVE_DIAGONAL: switch default to use adjoinable & vectorized version
12         (#undef SOLVE_DIAGONAL_LOWMEMORY); update output of exp. front_relax.bvp.
13    o model/src: solve_*diagonal.F
14       - replace division with multiplication by inverse (similar to original version)
15         update output of AD exp. global_ocean.90x40x15.
16       - fix pkg/gmredi/gmredi_calc_psi_bvp.F & pkg/ggl90/ggl90_calc.F
17         to enable the use of the vectorized & differentiable solve_tridiagonal.F
18       - test exp. global_ocean.90x40x15/input_ad: switch to advection scheme 20 for
19         vertical advection (to get solve_tridiagonal tested in AD mode).
20    o pkg/seaice: ECCO-CLIVAR merge:
21      1. seaice AREA relaxation
22         * CPP option: SEAICE_ALLOW_AREA_RELAXATION
23         * runtime flag: SEAICE_tauAreaObsRelax
24      2. modified global mean cost imbalance code: CPP option
25          ALLOW_SSH_GLOBMEAN_COST_CONTRIBUTION
26    o another iteration on solve_*diagonal.F
27       Make choices independent of AUTODIFF
28       Default will be the adjoinable vectorized version.
29       Alternative choices are:
30       * non-adjoinable original version with low memory footprint:
31         #define SOLVE_DIAGONAL_LOWMEMORY
32       * still adjoinable but does not vectorize (k as inner-most loop):
33         #define SOLVE_DIAGONAL_KINNER (keeping SOLVE_DIAGONAL_LOWMEMORY undef)
34    o testreport
35     - add option to use a home made wrapper around "make"
36     - remove MITGCM_IEEE env. variable (no longer active)
37    o pkg/shelfice
38     - improve computation of friction velocity for velocity dependent
39       exchange coefficients: include velocities into SHELFICEBoundaryLayer
40       block to average velocities vertically
41     - add TAF store directives for SHI_ALLOW_GAMMAFRICT
42    o Modify diagonal solvers, now three versions (upon request):
43      #ifndef SOLVE_DIAGONAL_AUTODIFF
44        1. default version (dating back a while ago)
45      #else /* def SOLVE_DIAGONAL_AUTODIFF */
46      # ifdef SOLVE_DIAGONAL_KINNER
47        2. adjoinable version with k-innermost loop (G. Forget)
48      # else
49        3. adjoinable vectorized version of 2.
50      # endif
51      #endif /* SOLVE_DIAGONAL_AUTODIFF */
52      All flags are currently set within routines, but could/should be moved to CPP-options.
53      Array bounds for 1. are as before, for 2.,3. cover the entire domain
54      (could be changed for 1. too).
55    o verification/lab_sea (fwd):
56      - update the 4 fwd lab_sea test experiment: no longer SEAICE_GROWTH_LEGACY,
57        use 7 categories (except hb87), new solve4temp params (except salt_plume),
58        constant salinity (=4) or variable salinity (salt_plume) done through
59        SItracer.
60    o pkg/seaice:
61      - rename parameters: SIsalFrac to SEAICE_saltFrac & SIsal0 to SEAICE_salt0;
62      - remove old parameters ( SEAICE_freeze, SEAICEturbFluxFormula, SEAICE_gamma_t,
63         SEAICE_gamma_t_frz, SEAICE_availHeatTaper & SEAICE_availHeatFracFrz)
64        from SEAICE_PARMS.h ; still need to fix seaice_cost_sst.F (broken when
65        SEAICE_freeze got retired) but already better than previously with
66        SEAICE_freeze=123456.7 deg.C;
67      - move setting of facOpenGrow/Melt from SEAICE_INIT_FIXED to SEAICE_READPARMS
68        (safer multi-threaded setting); always set SEAICEuseEVP;
69      - setting of ocean-ice turb. flux coeff: moved from SEAICE_CHECK to
70        SEAICE_READPARMS & SEAICE_INIT_FIXED (this fixes wrong summary report);
71        stop if multiple specifications for the same coeff; make sure default
72        SEAICE_mcPheePiston is compatible with drF(1) & deltaT.
73    o pkg/obcs:
74      - allow to switch to upwind 1rst order advection scheme for the advective
75        flux computation at the open-boundary; disabled for adjoint built.
76    o pkg/ptracers:
77      - rename PTRACERS_RESTART.h -> PTRACERS_START.h
78      - rename ptracers_fields_blocking_exchanges.F -> ptracers_fields_blocking_exch.F
79      - add parameter to decide when to start a tracer; use internal flag to
80        know which tracer to step-forward; switch this internal flag at the top
81        of forward_step.F (new S/R PTRACERS_SWITCH_ONOFF); for now, not enabled
82        for adjoint built.
83    o pkg/seaice:
84      - add SEAICE_SIZE.h anywhere in the code where SEAICE.h is included ;
85      - move MULTDIM declaration and setting from SEAICE.h to SEAICE_SIZE.h ;
86      - keep experiment offline_exf_seaice truly single category (set MULTDIM=1).
87    o pkg/ecco:
88      - fix writing of output file DiagnosCost_ClimSalt/Theta
89        and DiagnosCost_DriftSalt/Theta (if multi-tiles per proc).
90    o pkg/seaice:
91      - add missing initialisation of COR_ICE array in dynsolver.F
92      - merging SEAICE_MULTICATEGORY define and undef cases. Now the same code is
93        compiled either way, and is tested in all exps (multidim was only tested
94        in lab_sea ad before).
95      - cosmetic change to prepare for future addition of ITD. no change to results.
96        no defaults change.
97      - added run time param SEAICE_multDim (7 for SEAICE_MULTICATEGORY, 1 otherwise).
98      - by lack of adequate verification experiments, I further used custom versions
99        of global_ocean.cs32x15 to test multicat or not, with pickup or not. All
100        should be correct.
101      - avoid recomputations in ad.
102    o array initialisation in adjoint mode:
103      1) pkg/mom_common/mom_calc_ke.F:
104        add full array initialisation of KE inside mom_calc_ke.F (ALLOW_AUTODIFF_TAMC):
105        The S/R which calls MOM_CALC_KE initialises KE but in some recomputation
106        part this initialisation is gone, resulting in Floating Point Exception
107        (caught by open64 compiler with debug option).
108      2) model/src/convective_weights.F
109        set output convectCount over the full array range (instead of doing
110        an update): this fix a similar issue when called within recomputation (adjoint)
111        which could by-pass the initialisation (normally done in the caller S/R).
112    o pkg/seaice:
113      - final version of turbulent flux params, as agreed at MIT ice meet:
114           SEAICE_mcPheePiston (default is ~ 0.000875)
115           SEAICE_mcPheeTaper (default is 0.)
116           SEAICE_frazilFrac (defualt is 1.)
117           SEAICE_mcPheeStepFunc (default is false)
118      - changes results at trunction error level
119      - ifdef SEAICE_EXTERNAL_FLUXES, disallow SEAICE_waterAlbedo
120    o added pkg/frazil:
121      - see frazil_description.tex for details
122      - verification experiment is global_with_exf/input.yearly; changes output.yearly.txt
123    o pkg/shelfice/shelfice_thermodynamics.F
124      - fix exponents for velocity dependent exchange coefficients: change
125        from 2/3(=0) to 0.66666666666666667
126      - move computation of velocity dependent exchange coefficients into
127        separate loop, so that it applies to both thermodynamics
128      - move some divisions by constants out of loops
129    
130    checkpoint63j (2012/02/16)
131    o pkg/seaice:
132      - overhaul of seaice_summary.F after feb 2012 clean-up of seaice_growth.F etc.
133      - SItracer:  added run time params, and allow coupling to ocn salinity.
134    o pkg/seaice: remove (almost) all divisions by constants within loops
135      in seaice_growth.F and seaice_solve4temp.F, this changes (only) the cg2d
136      results of global_ocean.cs32x15.seaice from 16 to 11 digits (but only
137      those, caused by 1/QI -> recip_QI) -> update output.seaice.txt,
138      output_adm.seaice_dynmix.txt and also lab_sea: output_adm.evp.txt
139    o pkg/seaice :
140      - simplify McPhee tapering, and allow to use it with SEAICEturbFluxFormula
141        = 1 or 2, using newly added run time parameter SEAICE_availHeatTaper.
142      - fix d_AREAbyATM, d_AREAbyOCN, d_AREAbyICE diags I broke in r1.148.
143      - add permanent SItflux diag that corresponds to TFLUX but includes
144        ice+snow. Hence SItflux-TFLUX should match the ice+snow heat budget.
145      - allow activation/testing of a fix for suspected missing term in
146        ocn-ice heat budget (to be confirmed). To test this, you want to
147        undef SEAICE_DISABLE_HEATCONSFIX, and then set the run time param
148        SEAICEheatConsFix to .TRUE. that also allows the 'SIaaflux' diagnostic.
149      - no change in results, fwd or ad.
150    o global_ocean.cs32x15/results: 3 changes following from the pkg/seaice commit below:
151      - switch to variable freezing point.
152           Results change : cg2d -> 1 digits; ad -> 3-6-6 digits.
153      - bug fix : the sublimation term that was missing is now activated.
154           Results change : cg2d -> 2 digits; ad -> 8-6-6 digits.
155      - bug fix : flooding sign term for SIsal0.NE.0.
156           Result change : cg2d -> 8 digits; ad -> 11-12-9 digits.
157    o pkg/seaice:
158      - unified freezing point treatment : the old SEAICE_VARIABLE_FREEZING_POINT
159        is now the default, and the old default constant freezing point is recovered
160        with SEAICE_tempFrz0    = -1.96,
161             SEAICE_dTempFrz_dS = 0.,
162      - retire SEAICE_freeze (= the old way of specifycing the constant freezing point)
163      - remove ALLOW_SEAICE_FLOODING brackets; run time switch is already there.
164      - bug fix (thanks to M. Losch) : the sublimation term that was missing is now
165        activated. To reproduce old results with this bug define SEAICE_DISABLE_SUBLIM.
166      - bug fix (silly me) : flooding sign term (seaice_growth.F r 1.149line 1211)
167        was wrong for SIsal0.NE.0. Changes cs32x15 results (see above item for detail).
168      - bug fix (thanks to O. Jahn) : area loss for melting  got messed up in
169        seaice_growth r149 for legacy branch (no results change).
170      - introduce SEAICE_CAP_SUBLIM : caps sublimation heat flux in solve4temp (code
171        from I. Fenty).
172      - results did not change except for global_ocean.cs32x15, mostly due to the
173        switch to variable freezing point (see above item for detail).
