5      ==============================      ==============================
6    
7    o pkg/diagnostics (velocity potential solver):
8      - fix initialisation of main diagonal matrix (for overlap values)
9    o tools/build_options:
10      - towards single optfile for MPI and non-MPI built: merge few +mpi optfile
11        into previously non MPI one (linux_am64 pgf77,open64,pathf90,ifort11)
12      - linux_amd64_gfortran: merge +mpi_generic version into standard optfile:
13        * move IEEE flags to DEVEL section; take IEEE flags from +mpi_generic ;
14        * FAST case: for now, keep -O3 with ini_masks_etc.F in NOOPTFILES list;
15        and use "-devel" testreport option for standard testing on baudelaire.
16    o pkg/grdchk:
17      - Assume that all gradient-check position are within the same tile
18        corresponding to global indices (iGloTile,jGloTile) and that
19        positions (i,j indices or nbeg) are local to this tile;
20      - set tile local-indices and proc. number according to tile global-indices;
21      - remove grdchkwhichproc from namelist (retired param);
22      - send adjoint gradient to all procs so that all procs print it to STDOUT;
23      - switch on MPI test for global_ocean.90x40x15 AD test experiment.
24    o adding package bbl (Bottom Boundary Layer)
25      description in MITgcm/pkg/bbl/bbl_description.tex
26      example/test experiment in MITgcm_contrib/bbl
27    o adjoint verifications
28      - changed 5 experiments to multi-tiles
29        * global_ocean.90x40x15
30        * obcs_ctrl
31        * offline_exf_seaice
32        * tutorial_dic_adjoffline
33        * tutorial_tracer_adjsens
34        changed reference output for those that crossed tile boundaries
35        (changed choices of gradient check positions)
36      - with same tiling, switch on MPI test for the last 4 (add SIZE.h_mpi)
37      - temporary bug fix in grdchk_loc.F for obcs
38    o genmake2 & testreport
39      - add target "obj" (just for OBJFILES files) to Makefile;
40      - add option to specify FEXTRAFLAGS on command line.
41    o pkg/mypackage:
42      - remove bi,bj arguments from argument list of S/R MYPACKAGE_CALC_RHS
43    
44    checkpoint63a (2011/08/02)
45    o pkg/diagnostics (velocity potential):
46      - fix velocity-potential calculation when using OBCS: balance net inflow
47        at each level (new S/R OBCS_DIAG_BALANCE).
48      - fix some of the problems with OBCS in stream-function calculation.
49    o pkg/exf/exf_readparms.F
50      - make treatment of optional namelists (EXF_NML_04, EXF_NML_SGRUNOFF,
51        EXF_NML_OBCS) more consistent, so that you need not have these lists
52        in data.exf when they are not used.
53    o optim/optim_readdata.F:
54      - add some output about obcs variables that might help debugging
55      - add a check about nvarlength
56    o pkg/ctrl: once again, fix computation of endrec in s/r ctrl_init_rec
57    o pkg/diagnostics (velocity potential):
58      - fix mask for OBCS (still problems in stream-function with OBCS);
59      - add specific parameter (default = main code CG2D params) for solver;
60      - in case of poor convergence, use solution corresponding to lowest residual.
61    o pkg/seaice/seaice_growth.F: small changes that permit vectorizable
62      adjoint code. In general statements like tmpscal=fld(i,j) are problematic
63      and should be avoided where possible.
64    o model/src (rStar):
65      - include r* effect on reference-state (PhiRef) in totPhiHyd
66        (so that it's really the potential anomaly at the cell center);
67        affect solution only if z* with full pressure in EOS.
68      - test-exp global_ocean.90x40x15: reduce viscA4 (was not stable) and
69        update output (because of z* in totPhiHyd and viscA4 changes);
70      - keep the previous diagnostics as "PHIHYDcR" (closer to potential anomaly
71        @ constant r) until interpolation at constant r is implemented.
72    o pkg/diagnostics
73      - fix RCENTER diagnostics in case cell center is not at interface middle
74    o add code for TEOS-10 (www.teos-10.org, McDougall et al. 2011). Use
75      this eos with eosType = 'TEOS10', in data (PARM01). This eos implies
76      that THETA and SALT are "conservative temperature" and "absolute
77      salinity"
78    o pkg/ctrl
79      - fix computation of endrec in s/r ctrl_init_rec
80      - ctrl_pack/unpack_*: remove unused variables and some obsolete code
81    o pkg/seaice/seaice_growth.F
82      - fix recomputation with FENTY_AREA_EXPANSION_CONTRACTION code,
83        remove then obsolete STORE directives
84      - fix STORE directives for tice and tices, so that only the
85        appropriate part of the fields are stored (and not the entire
86        field); update global_ocean.cs32x15.seaice AD output.
87      - cosmetic changes: adjust CPP flags and indentation for better
88        legibilty
89    o pkg/autodiff: add mnc-output of adBottomDragFld (code contributed by
90      Chris Wilson)
91    o pkg/gmredi:
92       Add Sub-Meso Eddies parameterisation from Baylor (for now, disabled with TAF),
93       and test it in verification exp. "front_relax.bvp" (update output.bvp.txt)
94    
95    checkpoint63  (2011/07/11)
96    o pkg/exch2:
97     - rename+move: nTiles in W2_EXCH2_PARAMS.h --> exch2_nTiles in W2_EXCH2_TOPOLOGY.h
98     - exch2 version of Cumul-Sum routine: S/R W2_SET_MAP_CUMSUM set up the
99       (2*nTiles)x(nTiles) Cumul-Sum matrix and Master Proc collects all tiles X,Y
100       increments, calculates Cumul-Sum @ tile origin and sends results to each tile.
101    o pkg/diagnostics:
102     - deal with pairs of post-processed diags which are computed together; in
103       particular, re-order list of diags within 1 file to save 2nd computation.
104     - add S/R to compute velocity stream-function (called after velocity-potential
105       calculation) from divergence free transport -> new diagnostics "PsiVEL".
106     - add parameter to select grid-point location where PsiVEL == 0.
107    o eesupp/src:
108       new S/R to calculate cumulated sum on tiled array, corner grid-cell location
109       (specific S/R needed with exch2 topology - for now, just print an error msg)
110    o pkg/shelfice
111     - Implement friction velocity-dependent transfer coefficients following
112       Holland and Jenkins, JPO, 1999
113       Original code by M. Losch with small modifs.
114       Enable with CPP option SHI_ALLOW_GAMMAFRICT
115       and runtime flag SHELFICEuseGammaFrict
116    o verification lab_sea & global_ocean.cs32x15:
117     - use tools/xmakedepend (instead of cyrus_makedepend, in genmake_local):
118       does not miss some dependencies (but is slower) and also works with many files
119       (default makedepend limitation for AD built).
120     - use cyrus_makedepend in adjustment.128x64x1 (so that it still tested).
121    o pkg/diagnostics:
122     - add run-time parameter "useMissingValue" (def=False) to fill land-point
123        (i.e., where mask=0) with MissingValue ; used only in MNC output file.
124       This replaces CPP-option DIAGNOSTICS_MISSING_VALUE.
125     - Extend the use of "missing_value" setting from data.diagnostics for the case
126       of counter-diagnostics (where fraction-weight is zero). This applies both to
127       MNC and MDS output files.
128    o pkg/seaice/seaice_growth.F:
129      - add 'a priori' cap of latent heat flux based on actual mass considerations
130        when SEAICE_ADD_SUBLIMATION_TO_FWBUDGET is used in conjunction with the
131        non-legacy seaice_solve4temp.
132      - add diagnostic of the residual sublimation freshwater flux (the freshwater
133        flux taken from the ocean if the total actual latent heat fluxes exceed
134        the maximum)
135      - remove the CPP switch around the *_FWbySublim unit change and move diagnostic
136       fill for SIatmQnt, SIfwSubl, SIatmFW to the end of seaice_growth.F.
137      - add diagnostic of the actual sublimation freshwater flux (that is 0. ifndef
138       SEAICE_ADD_SUBLIMATION_TO_FWBUDGET) and of the latent heat flux (evap+sublim).
139      - bug fix : frWtrAtm needs a_FWbySublim ifdef SEAICE_ADD_SUBLIMATION_TO_FWBUDGET.
140      - bug fix : missing part to Martin's r_FWbySublim pathological case fix.
141    o verification 1D_ocean_ice_column:
142       made model domain truly 1x1x23 instead of 5x5x23 with only center cell (3,3,:) wet
143       update results
144    o pkg/diagnostics:
145     - Implement setting of "Post-Processed" diagnostics (corresponding to gdiag(5)='P')
146       which are not filled-up but computed from other diags ; In this case, the mate
147       diag points to the primary (filled-up) diag to used for post processing.
148     - Update Velocity-potential computation using post-processed diag framework.
149     ==> Change the ordering of fields and time-periods in MDS output file
150       when using periodic averaging: now writes one time record with the full set
151       of fields for this time period, then the next time reccord (it used to be
152       one field with the full set of time records then the next field).
153         Note: this is now similar to NetCDF (MNC) output file. <==
154    
155    checkpoint62z (2011/06/21)
156    o adjoint monitor:
157     - Add adjoint monitor output for packages exf, seaice
158       and update relevant testreport output
159    o pkg/seaice:
160     - re-order diags inits so that they appear in order in available_diagnostics.log
161     - added diags: hsnow thermo. rates of change, area preceeding ridiging process,
162       area/heff/hsnow preceeding thermodynamic growth/melt.
163     - modified diag: SIdA; output actual effect, as the description states.
164     - modified description: SIqneti, SIqneto, SIuheff, SIvheff, SIdAb*, HSNOW.
165     - retired redundant diags: SIyneg, SIfice, SIsnwice, SIthdgrh.
166       (SIyneg->SIdHbOCN; SIfice->SIdHbATC; SIsnwice->SIdHbFLO;
167        and SIthdgrh->SIdHbOCN+SIdHbATC+SIdHbATO)
168     - modified diags (2) : switch all SIdA*, SIdH*, SIdS* from delta to rates.
169     - added diagnostics for seaice generic tracers (SItr*).
170     - added SItrUnit and SItrNameLong run time param (for SItr* diags).
171     - in diag names, replaced 'PrTh' abbrev. of 'preceeding thermo' with 'PT'.
172     I. Fenty: 18-Jun-2011:
173     Minor changes to seaice package:
174     1) Retired old variables (A22, SEAICE_lhsublim, areaMax, areaMin, hiceMin) and
175        added some new ones (SEAICE_area_reg, SEAICE_hice_reg, SEAICE_area_floor)
176       - Differentiated "regularization variables" from "floor variables"
177        * areaMin became SEAICE_area_reg (old A22) and SEAICE_area_floor
178        * hiceMin became SEAICE_hice_reg (old hiceMin)
179          (with _reg meaning regularization variable)
180       - SEAICE_lhSublim becomes lhSublim, the sum of SEAICE_lhEvap and SEAICE_lhFusion
181        so as to ensure energy conservation when going between phases
182      - A22 was not used anywhere
183     2) Changed regularization procedure for heffActual and hsnowActual to ensure
184        well-boundedness and smooth adjoint in seaice_growth.F
185     3) Fixed a bug where seaice_solve4temp would not recognize ice-free grid cells
186        because the old regularization always set heffActual >= 0.05 cm
187     4) Changed the model so that the default behavior is to put a small (10^-5) "floor"
188        on AREA when HEFF > 0.
189      - went from requiring ALLOW_PRECLUDE_INFINITESIMAL_AREA to be defined to
190        requiring that DISABLE_AREA_FLOOR *not* be defined
191     Affected verifications:
192      - 1D_ocean_ice_column (output.txt output_adm.txt)
193      - global_ocean.cs32x15 (output.seaice.txt output_adm.seaice.txt)
194    o pkg/diagnostics:
195      - move MNC code from diagnostics_out.F into new diagnostics_mnc_out.F (2 S/R).
196      - rename S/R GETDIAG to DIAGNOSTICS_GET_DIAG and change type of 1rst argument
197        (was _RL, now integer) with option = 0 to retrieve all levels.
198      - add pieces of code to compute velocity potential at each level (new diagnostics
199        PhiVEL, works only when UVELMASS & VVELMASS are also turned on);
200        for now, using same params as CG2D (target-resisual, max Nb of iter ...).
201      - fix few issues with counter diagnostics in diagnostics_setdiag.F &
202        diagstats_setdiag.F (if diagnostic counter is itself a counter diag)
203        and in diagnostics_fract_fill.F (do not need a valid pointer for the
204        diagnostics counter-mate); check that definition of counter-diagnostic
205        includes a valid counter-mate (in diagnostics_set_levels.F).
206    o model/src (rStar):
207      - add rStar scaling factor in diags_phi_hyd.F (similar to calc_grad_phi_hyd.F);
208        affect solution only if z* with full pressure in EOS;
209        update output of test-exp global_ocean.90x40x15.
210    o pkg/seaice:
211      - introduce siEps=1e-5 parameter
212      - use areaMax in AREA update (part 4), consistent with ridging step (part 2.5).
213      - re-organize SEAICE_ADD_SUBLIMATION_TO_FWBUDGET code.
214      - introduce ALLOW_SITRACER and seaice_tracer_phys.F to handle generic seaice tracer.
215        For now it covers, and was tested for, ice salinity and age (attached to HEFF),
216        as well as ice cover age and ridging index (attached to AREA).
217        For now the run time parameters (in data.seaice/SEAICE_PARM03) are
218        SItrName (e.g. 'age') and SItrMate ('HEFF', which is the default, or 'AREA').
219        Up to SItrMaxNum=3 tracers can be used simultaneously.
220    o pkg/salt_plume:
221      -introduce SPsalFRAC run time parameter that sets the fraction of the
222       salt by-product of ice growth (SPsalFRAC*(1-SIsalFRAC)*salt typically)
223       that gets vertically redistributed (fluxed down) by pkg/salt_plume.
224    o model debug options:
225      - Switch reading of debugMode from S/R INI_PARMS (parameter file "data", stored
226        in PARAMS.h) to S/R EESET_PARMS (parameter file "eedata", stored in EEPARAMS.h).
227      - Refine debug-msg printing selection (3 new levels):
228        debugMode  : controls printing of debug messages (sequence of S/R calls).
229        debugLevel : controls printing of algorithm-relevant auxiliary/debug messages
230         debLevZero =  0 ; /* level of disabled aux. msg printing */
231         debLevA =  1 ; /* level of minimum  aux. msg printing */
232         debLevB =  2 ; /* level of low aux. print (report read-file opening)*/
233         debLevC =  3 ; /* level of moderate debug prt (most pkgs debug msg) */
234         debLevD =  4 ; /* level of enhanced debug prt (add DEBUG_STATS prt) */
235         debLevE =  5 ; /* level of extensive debug printing */
236        New debugLevel default: with default debugMode value (=F),
237          = 2 (debLevB) or = 1 (debLevA) in case ALLOW_AUTODIFF is defined.;
238          and if debugMode=T, default debugLevel = 4 (debLevD).
239        Relation with previous settings:
240         debLevB (=2) corresponds to former debLevA (=1)
241         debLevD (=4) corresponds to former debLevB (=2)
242        Note:
243         a) if debugLevel=0, skip WRITE_GRID call when nIter0 > 0 (same as before);
244         b) default debugLevel=1 is convenient in AD runs (avoid many file opening msgs);
245            to recover previous default, set debugLevel=2 (e.g. AD-test hs94.1x64x5)
246      - Add new parameter (printResidualFreq, read from PARM02 namelist) to print
247        detailed CG solvers convergence; off (=0) by default, except if debugLevel=5.
248    o pkg/obcs:
249      - change OBCSfixTopo default from True to False (should not change the results);
250        keep OBCSfixTopo=T in verification-exp. seaice_obcs.
251    o pkg/thsice:
252      - fix bug in thsice_calc_thickn.F (was introduced in version 1.18) in
253        2nd layer seaice sublimation (unlikely to happen)
254      - use Interior mask for OBCS in thsice_advection.F (similar to what is
255        done in gad_advection & seaice_advection).
256    o adjoint:
257      bug fix spotted by Gael Forget:
258      seaice_advection and thsice_advection still had
259      legacy CPP options to avoid CS corner updates for adjoint
260    o pkg/seaice:
261      => Change some of the defaults (2011/05/29):
262         - change SEAICEuseFluxForm default (from False to True)
263         - change DIFF1 default (from 0.004 m/s to 0. m/s)
264         And print warnings if DIFF1 is not set in data.seaice and centered
265          avection scheme is used without any diffusion.
266      also:
267      - fix seaice_diffusion calls in default AdvScheme part of seaice_advdiff.F;
268      - set SEAICEdiffKh[] default in the same way as SEAICEadvSch[]
269      - stop if DIFF1<>0 with SEAICEadvScheme <> 2, if DIFF1<>0 with any
270        other non-zero SEAICEdiffKh[] diffusivity, if SEAICEadvSalt=T with
271        #undef SEAICE_VARIABLE_SALINITY, if SEAICEadvAge=T with #undef SEAICE_AGE.
272      update results of test exp.:
273         lab_sea: output.fd (switch to AdvScheme=33 with diffKh=20)
274             output.hb87, output_adm.evp (SEAICEuseFluxForm=T and diffKh=200)
275             output_adm.noseaicedyn (SEAICEuseFluxForm=T)
276         offline_exf_seaice: output.seaicetd, output_adm (SEAICEuseFluxForm=T)
277         seaice_obcs: output (SEAICEuseFluxForm=T)
278      and prescribe old default for SEAICEuseFluxForm (=F) and DIFF1 (=0.004)
279          for standard fwd & AD lab_sea tests (to keep the same output).
280  o pkg/seaice/seaice_growth.F:  o pkg/seaice/seaice_growth.F:
281    - use Ian Fenty's capping formulas for actual ice    - use Ian Fenty's capping formulas for actual ice
