5      ==============================      ==============================
6    
7    o tools/build_options:
8      - towards single optfile for MPI and non-MPI built: merge few +mpi optfile
9        into previously non MPI one (linux_am64 pgf77,open64,pathf90,ifort11)
10      - linux_amd64_gfortran: merge +mpi_generic version into standard optfile:
11        * move IEEE flags to DEVEL section; take IEEE flags from +mpi_generic ;
12        * FAST case: for now, keep -O3 with ini_masks_etc.F in NOOPTFILES list;
13        and use "-devel" testreport option for standard testing on baudelaire.
14    o pkg/grdchk:
15      - Assume that all gradient-check position are within the same tile
16        corresponding to global indices (iGloTile,jGloTile) and that
17        positions (i,j indices or nbeg) are local to this tile;
18      - set tile local-indices and proc. number according to tile global-indices;
19      - remove grdchkwhichproc from namelist (retired param);
20      - send adjoint gradient to all procs so that all procs print it to STDOUT;
21      - switch on MPI test for global_ocean.90x40x15 AD test experiment.
22    o adding package bbl (Bottom Boundary Layer)
23      description in MITgcm/pkg/bbl/bbl_description.tex
24      example/test experiment in MITgcm_contrib/bbl
25    o adjoint verifications
26      - changed 5 experiments to multi-tiles
27        * global_ocean.90x40x15
28        * obcs_ctrl
29        * offline_exf_seaice
30        * tutorial_dic_adjoffline
31        * tutorial_tracer_adjsens
32        changed reference output for those that crossed tile boundaries
33        (changed choices of gradient check positions)
34      - with same tiling, switch on MPI test for the last 4 (add SIZE.h_mpi)
35      - temporary bug fix in grdchk_loc.F for obcs
36    o genmake2 & testreport
37      - add target "obj" (just for OBJFILES files) to Makefile;
38      - add option to specify FEXTRAFLAGS on command line.
39    o pkg/mypackage:
40      - remove bi,bj arguments from argument list of S/R MYPACKAGE_CALC_RHS
41    
42    checkpoint63a (2011/08/02)
43    o pkg/diagnostics (velocity potential):
44      - fix velocity-potential calculation when using OBCS: balance net inflow
45        at each level (new S/R OBCS_DIAG_BALANCE).
46      - fix some of the problems with OBCS in stream-function calculation.
47    o pkg/exf/exf_readparms.F
48      - make treatment of optional namelists (EXF_NML_04, EXF_NML_SGRUNOFF,
49        EXF_NML_OBCS) more consistent, so that you need not have these lists
50        in data.exf when they are not used.
51    o optim/optim_readdata.F:
52      - add some output about obcs variables that might help debugging
53      - add a check about nvarlength
54    o pkg/ctrl: once again, fix computation of endrec in s/r ctrl_init_rec
55    o pkg/diagnostics (velocity potential):
56      - fix mask for OBCS (still problems in stream-function with OBCS);
57      - add specific parameter (default = main code CG2D params) for solver;
58      - in case of poor convergence, use solution corresponding to lowest residual.
59    o pkg/seaice/seaice_growth.F: small changes that permit vectorizable
60      adjoint code. In general statements like tmpscal=fld(i,j) are problematic
61      and should be avoided where possible.
62    o model/src (rStar):
63      - include r* effect on reference-state (PhiRef) in totPhiHyd
64        (so that it's really the potential anomaly at the cell center);
65        affect solution only if z* with full pressure in EOS.
66      - test-exp global_ocean.90x40x15: reduce viscA4 (was not stable) and
67        update output (because of z* in totPhiHyd and viscA4 changes);
68      - keep the previous diagnostics as "PHIHYDcR" (closer to potential anomaly
69        @ constant r) until interpolation at constant r is implemented.
70    o pkg/diagnostics
71      - fix RCENTER diagnostics in case cell center is not at interface middle
72    o add code for TEOS-10 (www.teos-10.org, McDougall et al. 2011). Use
73      this eos with eosType = 'TEOS10', in data (PARM01). This eos implies
74      that THETA and SALT are "conservative temperature" and "absolute
75      salinity"
76    o pkg/ctrl
77      - fix computation of endrec in s/r ctrl_init_rec
78      - ctrl_pack/unpack_*: remove unused variables and some obsolete code
79    o pkg/seaice/seaice_growth.F
80      - fix recomputation with FENTY_AREA_EXPANSION_CONTRACTION code,
81        remove then obsolete STORE directives
82      - fix STORE directives for tice and tices, so that only the
83        appropriate part of the fields are stored (and not the entire
84        field); update global_ocean.cs32x15.seaice AD output.
85      - cosmetic changes: adjust CPP flags and indentation for better
86        legibilty
87    o pkg/autodiff: add mnc-output of adBottomDragFld (code contributed by
88      Chris Wilson)
89    o pkg/gmredi:
90       Add Sub-Meso Eddies parameterisation from Baylor (for now, disabled with TAF),
91       and test it in verification exp. "front_relax.bvp" (update output.bvp.txt)
92    
93    checkpoint63  (2011/07/11)
94    o pkg/exch2:
95     - rename+move: nTiles in W2_EXCH2_PARAMS.h --> exch2_nTiles in W2_EXCH2_TOPOLOGY.h
96     - exch2 version of Cumul-Sum routine: S/R W2_SET_MAP_CUMSUM set up the
97       (2*nTiles)x(nTiles) Cumul-Sum matrix and Master Proc collects all tiles X,Y
98       increments, calculates Cumul-Sum @ tile origin and sends results to each tile.
99    o pkg/diagnostics:
100     - deal with pairs of post-processed diags which are computed together; in
101       particular, re-order list of diags within 1 file to save 2nd computation.
102     - add S/R to compute velocity stream-function (called after velocity-potential
103       calculation) from divergence free transport -> new diagnostics "PsiVEL".
104     - add parameter to select grid-point location where PsiVEL == 0.
105    o eesupp/src:
106       new S/R to calculate cumulated sum on tiled array, corner grid-cell location
107       (specific S/R needed with exch2 topology - for now, just print an error msg)
108    o pkg/shelfice
109     - Implement friction velocity-dependent transfer coefficients following
110       Holland and Jenkins, JPO, 1999
111       Original code by M. Losch with small modifs.
112       Enable with CPP option SHI_ALLOW_GAMMAFRICT
113       and runtime flag SHELFICEuseGammaFrict
114    o verification lab_sea & global_ocean.cs32x15:
115     - use tools/xmakedepend (instead of cyrus_makedepend, in genmake_local):
116       does not miss some dependencies (but is slower) and also works with many files
117       (default makedepend limitation for AD built).
118     - use cyrus_makedepend in adjustment.128x64x1 (so that it still tested).
119    o pkg/diagnostics:
120     - add run-time parameter "useMissingValue" (def=False) to fill land-point
121        (i.e., where mask=0) with MissingValue ; used only in MNC output file.
122       This replaces CPP-option DIAGNOSTICS_MISSING_VALUE.
123     - Extend the use of "missing_value" setting from data.diagnostics for the case
124       of counter-diagnostics (where fraction-weight is zero). This applies both to
125       MNC and MDS output files.
126    o pkg/seaice/seaice_growth.F:
127      - add 'a priori' cap of latent heat flux based on actual mass considerations
128        when SEAICE_ADD_SUBLIMATION_TO_FWBUDGET is used in conjunction with the
129        non-legacy seaice_solve4temp.
130      - add diagnostic of the residual sublimation freshwater flux (the freshwater
131        flux taken from the ocean if the total actual latent heat fluxes exceed
132        the maximum)
133      - remove the CPP switch around the *_FWbySublim unit change and move diagnostic
134       fill for SIatmQnt, SIfwSubl, SIatmFW to the end of seaice_growth.F.
135      - add diagnostic of the actual sublimation freshwater flux (that is 0. ifndef
136       SEAICE_ADD_SUBLIMATION_TO_FWBUDGET) and of the latent heat flux (evap+sublim).
137      - bug fix : frWtrAtm needs a_FWbySublim ifdef SEAICE_ADD_SUBLIMATION_TO_FWBUDGET.
138      - bug fix : missing part to Martin's r_FWbySublim pathological case fix.
139    o verification 1D_ocean_ice_column:
140       made model domain truly 1x1x23 instead of 5x5x23 with only center cell (3,3,:) wet
141       update results
142    o pkg/diagnostics:
143     - Implement setting of "Post-Processed" diagnostics (corresponding to gdiag(5)='P')
144       which are not filled-up but computed from other diags ; In this case, the mate
145       diag points to the primary (filled-up) diag to used for post processing.
146     - Update Velocity-potential computation using post-processed diag framework.
147     ==> Change the ordering of fields and time-periods in MDS output file
148       when using periodic averaging: now writes one time record with the full set
149       of fields for this time period, then the next time reccord (it used to be
150       one field with the full set of time records then the next field).
151         Note: this is now similar to NetCDF (MNC) output file. <==
152    
153    checkpoint62z (2011/06/21)
154    o adjoint monitor:
155     - Add adjoint monitor output for packages exf, seaice
156       and update relevant testreport output
157    o pkg/seaice:
158     - re-order diags inits so that they appear in order in available_diagnostics.log
159     - added diags: hsnow thermo. rates of change, area preceeding ridiging process,
160       area/heff/hsnow preceeding thermodynamic growth/melt.
161     - modified diag: SIdA; output actual effect, as the description states.
162     - modified description: SIqneti, SIqneto, SIuheff, SIvheff, SIdAb*, HSNOW.
163     - retired redundant diags: SIyneg, SIfice, SIsnwice, SIthdgrh.
164       (SIyneg->SIdHbOCN; SIfice->SIdHbATC; SIsnwice->SIdHbFLO;
165        and SIthdgrh->SIdHbOCN+SIdHbATC+SIdHbATO)
166     - modified diags (2) : switch all SIdA*, SIdH*, SIdS* from delta to rates.
167     - added diagnostics for seaice generic tracers (SItr*).
168     - added SItrUnit and SItrNameLong run time param (for SItr* diags).
169     - in diag names, replaced 'PrTh' abbrev. of 'preceeding thermo' with 'PT'.
170     I. Fenty: 18-Jun-2011:
171     Minor changes to seaice package:
172     1) Retired old variables (A22, SEAICE_lhsublim, areaMax, areaMin, hiceMin) and
173        added some new ones (SEAICE_area_reg, SEAICE_hice_reg, SEAICE_area_floor)
174       - Differentiated "regularization variables" from "floor variables"
175        * areaMin became SEAICE_area_reg (old A22) and SEAICE_area_floor
176        * hiceMin became SEAICE_hice_reg (old hiceMin)
177          (with _reg meaning regularization variable)
178       - SEAICE_lhSublim becomes lhSublim, the sum of SEAICE_lhEvap and SEAICE_lhFusion
179        so as to ensure energy conservation when going between phases
180      - A22 was not used anywhere
181     2) Changed regularization procedure for heffActual and hsnowActual to ensure
182        well-boundedness and smooth adjoint in seaice_growth.F
183     3) Fixed a bug where seaice_solve4temp would not recognize ice-free grid cells
184        because the old regularization always set heffActual >= 0.05 cm
185     4) Changed the model so that the default behavior is to put a small (10^-5) "floor"
186        on AREA when HEFF > 0.
187      - went from requiring ALLOW_PRECLUDE_INFINITESIMAL_AREA to be defined to
188        requiring that DISABLE_AREA_FLOOR *not* be defined
189     Affected verifications:
190      - 1D_ocean_ice_column (output.txt output_adm.txt)
191      - global_ocean.cs32x15 (output.seaice.txt output_adm.seaice.txt)
192    o pkg/diagnostics:
193      - move MNC code from diagnostics_out.F into new diagnostics_mnc_out.F (2 S/R).
194      - rename S/R GETDIAG to DIAGNOSTICS_GET_DIAG and change type of 1rst argument
195        (was _RL, now integer) with option = 0 to retrieve all levels.
196      - add pieces of code to compute velocity potential at each level (new diagnostics
197        PhiVEL, works only when UVELMASS & VVELMASS are also turned on);
198        for now, using same params as CG2D (target-resisual, max Nb of iter ...).
199      - fix few issues with counter diagnostics in diagnostics_setdiag.F &
200        diagstats_setdiag.F (if diagnostic counter is itself a counter diag)
201        and in diagnostics_fract_fill.F (do not need a valid pointer for the
202        diagnostics counter-mate); check that definition of counter-diagnostic
203        includes a valid counter-mate (in diagnostics_set_levels.F).
204    o model/src (rStar):
205      - add rStar scaling factor in diags_phi_hyd.F (similar to calc_grad_phi_hyd.F);
206        affect solution only if z* with full pressure in EOS;
207        update output of test-exp global_ocean.90x40x15.
208    o pkg/seaice:
209      - introduce siEps=1e-5 parameter
210      - use areaMax in AREA update (part 4), consistent with ridging step (part 2.5).
211      - re-organize SEAICE_ADD_SUBLIMATION_TO_FWBUDGET code.
212      - introduce ALLOW_SITRACER and seaice_tracer_phys.F to handle generic seaice tracer.
213        For now it covers, and was tested for, ice salinity and age (attached to HEFF),
214        as well as ice cover age and ridging index (attached to AREA).
215        For now the run time parameters (in data.seaice/SEAICE_PARM03) are
216        SItrName (e.g. 'age') and SItrMate ('HEFF', which is the default, or 'AREA').
217        Up to SItrMaxNum=3 tracers can be used simultaneously.
218    o pkg/salt_plume:
219      -introduce SPsalFRAC run time parameter that sets the fraction of the
220       salt by-product of ice growth (SPsalFRAC*(1-SIsalFRAC)*salt typically)
221       that gets vertically redistributed (fluxed down) by pkg/salt_plume.
222    o model debug options:
223      - Switch reading of debugMode from S/R INI_PARMS (parameter file "data", stored
224        in PARAMS.h) to S/R EESET_PARMS (parameter file "eedata", stored in EEPARAMS.h).
225      - Refine debug-msg printing selection (3 new levels):
226        debugMode  : controls printing of debug messages (sequence of S/R calls).
227        debugLevel : controls printing of algorithm-relevant auxiliary/debug messages
228         debLevZero =  0 ; /* level of disabled aux. msg printing */
229         debLevA =  1 ; /* level of minimum  aux. msg printing */
230         debLevB =  2 ; /* level of low aux. print (report read-file opening)*/
231         debLevC =  3 ; /* level of moderate debug prt (most pkgs debug msg) */
232         debLevD =  4 ; /* level of enhanced debug prt (add DEBUG_STATS prt) */
233         debLevE =  5 ; /* level of extensive debug printing */
234        New debugLevel default: with default debugMode value (=F),
235          = 2 (debLevB) or = 1 (debLevA) in case ALLOW_AUTODIFF is defined.;
236          and if debugMode=T, default debugLevel = 4 (debLevD).
237        Relation with previous settings:
238         debLevB (=2) corresponds to former debLevA (=1)
239         debLevD (=4) corresponds to former debLevB (=2)
240        Note:
241         a) if debugLevel=0, skip WRITE_GRID call when nIter0 > 0 (same as before);
242         b) default debugLevel=1 is convenient in AD runs (avoid many file opening msgs);
243            to recover previous default, set debugLevel=2 (e.g. AD-test hs94.1x64x5)
244      - Add new parameter (printResidualFreq, read from PARM02 namelist) to print
245        detailed CG solvers convergence; off (=0) by default, except if debugLevel=5.
246    o pkg/obcs:
247      - change OBCSfixTopo default from True to False (should not change the results);
248        keep OBCSfixTopo=T in verification-exp. seaice_obcs.
249    o pkg/thsice:
250      - fix bug in thsice_calc_thickn.F (was introduced in version 1.18) in
251        2nd layer seaice sublimation (unlikely to happen)
252      - use Interior mask for OBCS in thsice_advection.F (similar to what is
253        done in gad_advection & seaice_advection).
254    o adjoint:
255      bug fix spotted by Gael Forget:
256      seaice_advection and thsice_advection still had
257      legacy CPP options to avoid CS corner updates for adjoint
258    o pkg/seaice:
259      => Change some of the defaults (2011/05/29):
260         - change SEAICEuseFluxForm default (from False to True)
261         - change DIFF1 default (from 0.004 m/s to 0. m/s)
262         And print warnings if DIFF1 is not set in data.seaice and centered
263          avection scheme is used without any diffusion.
264      also:
265      - fix seaice_diffusion calls in default AdvScheme part of seaice_advdiff.F;
266      - set SEAICEdiffKh[] default in the same way as SEAICEadvSch[]
267      - stop if DIFF1<>0 with SEAICEadvScheme <> 2, if DIFF1<>0 with any
268        other non-zero SEAICEdiffKh[] diffusivity, if SEAICEadvSalt=T with
269        #undef SEAICE_VARIABLE_SALINITY, if SEAICEadvAge=T with #undef SEAICE_AGE.
270      update results of test exp.:
271         lab_sea: output.fd (switch to AdvScheme=33 with diffKh=20)
272             output.hb87, output_adm.evp (SEAICEuseFluxForm=T and diffKh=200)
273             output_adm.noseaicedyn (SEAICEuseFluxForm=T)
274         offline_exf_seaice: output.seaicetd, output_adm (SEAICEuseFluxForm=T)
275         seaice_obcs: output (SEAICEuseFluxForm=T)
276      and prescribe old default for SEAICEuseFluxForm (=F) and DIFF1 (=0.004)
277          for standard fwd & AD lab_sea tests (to keep the same output).
278    o pkg/seaice/seaice_growth.F:
279      - use Ian Fenty's capping formulas for actual ice
280      thickness thoughout EVOLUTION branch.
281      - put treatment pathological case #2) in CPP brackets
282      (ALLOW_AVOID_INFINITESIMAL_AREA, undef by default).
283      - update global_ocean.cs32x15 and 1D_ocean_ice_colum results accordingly.
284    o pkg/seaice:
285      - seaice_diffusion.F : remove the min(DX,DY) factor permanently;
286      pass the Laplacian diffusivity (in m^2/s) diffKh as a parameter;
287      also pass fac as a param, which can be 1. (to update the tendency
288      field) or the time step (to update the field itself).
289      - seaice_advdiff.F: for multidim, call seaice_diffusion with
290      e.g. SEAICEdiffKhHeff and with fac=1; for single-dim, call
291      seaice_diffusion with e.g. SEAICEdiffKhHeff and with fac=time step.
292      - SEAICE_PARAMS.h, seaice_readparms.F, seaice_check.F :
293      hooks to handle SEAICEdiffKhHeff, SEAICEdiffKhArea, etc.
294    o pkg/seaice:
295      diffusion with centered advection scheme (diffus.F & advect.F):
296      - simplify S/R DIFFUS (put deltaT & DIFF1 factor outside, move EXCH outside)
297        to just compute the laplacian of input-field.
298      - unroll k loop (harmonic,biharmonic diff) in advect.F to save 1 exch call.
299      - fix flux-form version in diffus.F to conserve tracer.
300      update output of lab_sea.fd & lab_sea.hb87 (1rst set of modif affects
301       machine truncation) and lab_sea.salt_plume (conservative flux-form modif)
302    
303    checkpoint62y (2011/05/26)
304    o pkg/seaice:
305     - seaice_growth.F : in EVOLUTION branch, always include
306       a_QSWbyATM_cover in qnet (as it should be).
307     - verification/global_ocean.cs32x15 : update results accordingly
308       (output.seaice.txt output_adm.seaice.txt).
309    o pkg/seaice + obcs:
310     - use maskInW & maskInS in multi-dim advection and biharmonic diffusion:
311       equivalent of assuming no tracer gradient outside the OB region.
312       update output of seaice_obcs (uses DIFF1 <>0 => biharmonic diffusion)
313     - remove calls to OBCS_COPY_TRACER after EXCH calls (no longer needed
314       after changes above);
315     - obcs+seaice cleaning: apply seaice-tracer OB values to tracer field
316       only at OB location (instead of over a band of OLx width).
317    o pkg/seaice:
318     - fix wrong indices in old (non Flux-Form) diffusion default S/R diffus.F
319       (dxG(I+1, ...) changed to dxG(I, ...), no impact on Lat-Lon grid)
320    o pkg/obcs:
321      - split header file "OBCS.h" into 4 separated files:
322        OBCS_PARAMS.h, OBCS_GRID.h, OBCS_FIELDS.h & OBCS_SEAICE.h
323       Note: OBCS_PARAMS.h & OBCS_GRID.h can be included without OBCS_OPTIONS.h
324         (contain no conditional statement which depends on OBCS options).
325      - move "useOBCSYearlyFields" from "data.obcs" (hold in OBCS_PARAMS.h)
326        to parameter file "data.exf", namelist EXF_NML_OBCS (in EXF_PARAM.h).
327    o ctrl, cost, grdchk & autodiff pkgs:
328      - make options file more standard (like other {PKG}_OPTIONS.h file but
329        with AD_CONFIG.h); clean-up some of the included header files.
330    o pkg/obcs:
331      - do not mask tracer when applying OB (tracer == 0 could generate problems)
332      - apply tracer OB values to tracer field only at OB location (instead of
333        over a band of OLx width)
334      - clean-up obcs_apply_w.F & obcs_apply_eta.F (since less calls to these S/R)
335      - remove OBCS_MULTIDIM_OLD_VERSION code in gad_advection.F and remove
336        obcs_apply_tloc.F & obcs_apply_sloc.F
337    o obcs in model/src:
338      - call OBCS_APPLY_W only if NonHydrostatic.
339      - call OBCS_APPLY_ETA only if NonLinFreeSurf.
340      - reset dEtaHdt and wVel to zero outside OB interior region ;
341      - leave tracer unchanged outside OB interior region: This has no effect
342        on the solution but just to prevent unrealistic tracer value outside OB.
343      - zero out velocity outside OB interior region: This has no effect on
344        the solution but just to prevent unrealistic velocity outside OB.
345    o obcs and non-lin free-surf:
346       move call to OBCS_APPLY_R_STAR from update_r_star.F to calc_r_star.F
347       and call to OBCS_APPLY_SURF_DR from update_surf_dr.F to calc_surf_dr.F
348       + add argument "etaFld" to OBCS_APPLY_R_STAR & OBCS_APPLY_SURF_DR:
349       this fixes missing EXCH + get consistent eta OB value (+ fix restart).
350       update results of test-exp. exp4(nlfs).
351    o exp4 (nlfs) test-exp:
352       use OBC for Eta at Western & Eastern OB (to test prescribing Eta
353       with NonLin-FreeSurf); update output.nlfs.txt
354    o obcs and 2d/3d solver norm:
355       use interior masks (maskInC) to cancel out cg2d & cg3d matrix coeff at OB
356       and outside OB interior region (will allow to place OB further inside the
357       domain). Depending on the domain, can affects cg2d-Norm (previous
358       cancellation outside OB was only partial), e.g. in exp4 & obcs_ctrl,
359       and cg3d-Norm (previous Norm was computed before canceling OB terms),
360       e.g. in tutorial_plume_on_slope.
361      - update output of exp.: exp4 (x2), obcs_ctrl and tutorial_plume_on_slope.
362    o pkg rbcs:
363      - split RBCS.h into 3 files: RBCS_SIZE.h, RBCS_PARAMS.h & RBCS_FIELDS.h
364      - add capability to apply relaxation to horizontal velocity uVel & vVel.
365    o pkg/grdchk: add gradient check for control variable xx_shifwflx
366    o pkg/shelfice/shelfice_init_fixed.F
367      fix CPP-flag combinations
368    o pkg/seaice: Merge iceage code of Pierre Rampal
369      * update/change/correct ice age calculations
370      * add age updates for pathological cases
371      Probably needs more testing...
372    
373    checkpoint62x (2011/05/13)
374    o pkg/mom_vecinv:
375       high-order vorticity scheme: use interior masks (maskInW & S)
376       to zero-out (outside OB) gradient of vorticity.
377    o verification exp.:
378       turn on "useEnergyConservingCoriolis" (better discretisation) in exp.
379       hs94.128x64x5 and seaice_obcs ; update results.
380    o pkg/obcs:
381      fix bug in OBeta for YZ sections in obcs_exf_load.F
382    o pkg/ctrl, pkg/shelfice, and optim:
383      - add new control variable xx_shifwflx (fresh water flux underneath ice
384        shelves). This is almost as tedious as obcs-ctrl, because the
385        variables needs its own mask.
386      - add a cost function term that penalizes the deviation of xx_shifwflx
387        from the first guess (zero) in analogy to other control variables
388    o pkg/shelfice:
389      - start basic adjoint
390    o pkg/ctrl:
391      - remove extra 2D field "for good measure" when initializing in
392        ctrl_set_globfld_[xy/xz/yz].F
393      - replace hard coded precision 32 (a bug) in ctrl_map_ini_gen by ctrlprec
394      - improve error messages in ctrl_set_unpack_*
395    o OBC implementation in momentum:
396       use interior masks (maskInC,W & S) in momentum S/R:
397       - multiply divergence, tension and some del^i.u or del^j.v by maskInC
398       - multiply del2u,del2v by maskInW/S (biharmonic viscosity)
399       - multiply horiz. grad of vorticity by maskInW/S (in Leith scheme)
400       - multiply gradient of wVel by maskInW/S in del2w calculation (NonHyd)
401       Motivation: fix/clean implementation of OBC with biharmonic-viscosity
402        (and also with Leith/Smagorinsky harmonic-viscosity).
403       Update output of experiment dome and exp4 (+nlfs).
404    o exp4 test-exp:
405      - turn on: nonHydrostatic, exactConserv, viscA4 (with momDissip_In_AB=F)
406        and prescribe time-varying OB (without pkg/exf) for zonal-velocity
407        at Western & Eastern Boundaries (+/- 1 per-cent); Also prescribe
408        time-varying OB at Western-side for wVel (NonHyd); update output.
409      - add secondary set-up (.nlfs) using NonLin FreeSurf (z*) + mom_vecinv
410        and biharmonic-viscosity ; also use prescribed time varying OB.
411    o pkg/obcs:
412      fix bug in OBWeta,OBWeta indices in obcs_apply_r_star.F
413    o model/src:
414      - fix startTime setting when baseTime<>0 & nIter0=0 are specified ;
415      - initialise startTime & nIter0 with unlikely values: allows to set one
416        from the other without ambiguity.
417    o seaice_obcs test-exp.:
418      add small diffK4T,S to test biharmonic diffusivity with OBCS ; update output.
419    o pkg/obcs:
420      - remove calls to OBCS_COPY_TRACER after EXCH for T,S & pTracer:
421        no longer needed with maskInC,W,S in pkg/generic_advdiff.
422    o pkg/seaice:
423      - retired SEAICE_SALINITY and SEAICE_salinity in favor of
424        SEAICE_VARIABLE_SALINITY and SIsalFRAC, respectively.
425      - fixed bug in the initialization of sea ice salinity variable HSALT
426        in seaice_init_varia.F  (removed dependence on ICE2WATR)
427    o fizhi-cs test exp.:
428       switch reference output convention for these 2 non-standard test-exp,
429        from: pgi  6.1-5 on faulks (FC.6, -of linux_ia32_pgf77+authors_fc5)
430          to: ifort 11.1 on baudelaire (FC.13, -of linux_amd64_ifort11)
431       reason: faulks might get retired soon and pkg/fizhi has still Pb with gfortran
432    o model/inc:
433      - change type of PmEpR array (from _RS to _RL) to fix restart (with "-use_r4")
434        of exp. global_ocean.90x40x15 (Suncronous time-stepping + Real-FW + NonLin-FS)
435    o pkg/seaice:
436      - fix calculation of saltFlux and saltPlumeFlux when using SEAICE_SALINITY
437    o verification/lab_sea, 1D_ocean_ice_column, seaice_obcs, global_ocean.cs32x15
438      - updated output*.txt files due to bug fixes in salt, saltPlumeFlux,
439        and initial HSALT
440    
441    checkpoint62w (2011/04/26)
442    o pkg/mom_fluxform:
443      - fix calculation of del2u & del2v (no-slip BC) when using Non-Lin Free-Surf.
444      - use parameter "sideDragFactor" in no-slip BC side-drag part.
445      - update output of exp. global_ocean.90x40x15
446    o pkg/mom_vecinv:
447      mask del2u & del2v (no effect on results, but cleaner & closer to mom_fluxform)
448    o update seaice exp.:
449      use more consistent parameter values (remove "backward compatability only":
450       ICE2WATR, SEAICE_lhSublim, SEAICE_cpAir, SEAICE_rhoAir + set rhoConstFresh)
451      related to thermodynamics seaice. Update output (fwd+AD) of exp.:
452       1D_ocean_ice_column (x2), lab_sea (x8), ioffline_exf_seaice (x2) & seaice_obcs
453    o update test-exp global_ocean.90x40x15:
454      o use default CD_CODE_OPTIONS file (Adams-Bashforth on CD Mom & Coriolis).
455      o increase Overlap size from 2 to 3 (to allow to test bi-harmonic Visc.)
456      o new pickup-files from a 100.yr run with pkg/down_slope (input.dwnslp params)
457      o turn on zStar & viscA4 in standard set-up (dir input/)
458        and update output files: output.txt & output.dwnslp.txt
459    o new AD-test experiment: obcs_ctrl
460      (From Matt MITgcm_Contrib/SOSE/BoxAdj) to test OBCS as control vector.
461    o pkg/dic:
462      fix two bugs in handling water vapour pressure in carbonate chemistry
463      and air-sea fluxes. Found by Val Bennington and Galen McKinley
464      (add DIC Option = WATERVAP_BUG to recover old results)
465      update output of tutorial_global_oce_biogeo (fwd+AD) & tutorial_dic_adjoffline
466    o adding allowInteriorFreezing option to check for water below freezing point
467      at depth and bring the negative heat anomaly to the surface level
468    o pkgs _fields_load:
469      - extend GET_PERIODIC_INTERVAL to deal with non-periodic case (from pkg/rbcs)
470      - use new S/R GET_PERIODIC_INTERVAL in pkgs:
471        bulk_force, cheapaml, cfc, dic, obcs (+ ctrl/ctrl_get_gen_rec), offline and
472        rbcs to get interpolation weights and time reccord number.
473      - fix multi-threading in aim_fields_load.F
474      - apply EXCH to temp arrays [0,1] after reading in dic_fields_load.F
475    o external_fields_load:
476      new S/R GET_PERIODIC_INTERVAL to calculate which time-record (and linear
477       interpolation weights) to use in a periodic time-series ; do not divide by
478       time-step to convert to integer:
479       - this fixes case where externForcingPeriod is not multiple of time-step
480          (Thanks to Christopher L. Wolfe)
481       - this fixes case where externForcingPeriod is an odd multiple of time-step
482         (was wrong by half of time-step); update results of tutorial_global_oce_in_p.
483      store index of time-record which is currently loaded:
484       - works without any assumption on sequence of calls to EXTERNAL_FIELDS_LOAD ;
485       - needed for the adjoint but not yet used because of extensive recomputations;
486         (to be fixed soon)
487    
488    checkpoint62v (2011/04/02)
489    o verification/1D_ocean_ice_column added to test Ian Fenty's
490      pkg/seaice_growth.F modifications for improving sea ice code differentiability
491    o update output of exp4, internal_wave, seaice_obcs, tutorial_plume_on_slope
492      (new velocity statistics after changing maskInW & maskInS definition)
493    o pkg/generic_advdiff with OBCS:
494      use maksInW & maskInS in advective flux and in biharmonic diffusion calculation:
495      equivalent to assumption of no tracer gradient outside the OB region.
496      This will affect the results if using obcs+biharmonic diffusion.
497      update output_adm.txt of experiment bottom_ctrl_5x5 (not expected since no obc)
498    o pkg/obcs:
499      change definition of maskInW & maskInS: leave OB edges inside (maskIn=1)
500      (e.g., maskInW(OB_Ie)=1 ) so that velocity normal-component at OB is still
501      in Interior region. No impact on solution but affects Velocity monitor stats.
502    o pkg/ptracers (adjoint)
503      New option AUTODIFF_PTRACERS_SPLIT_FILES for writing separate
504      tape file for each tracer
505    o model/inc/src and pkg/autodiff: add parameters that allow to turn
506      of parts of the adjoint code at run time. For now, there are only
507      useKPPinAdMode, useGMrediInAdMode, and useSEAICEinAdMode. These
508      parameters are set in data.pkg.
509      This is the lazy coward's version of doing this, but still useful for
510      debugging. In order to do it right, everything needs to be moved to
511      pkg/autodiff.
512    o pkg/autodiff: fix global_sum_tile_ad.F by resetting adsumPhi at
513      the end; this fixes the adjoint balancing code for open boundaries.
514    o pkg/ctrl:
515      - change behavior of xx_${varname}period to be analogous to exf-conventions:
516        xx_${varname}period =   0.,  means time-independent control part
517        xx_${varname}period = -12., means one-year-periodic monthly control part
518      - introduce helper routine ctrl_init_rec (part of ctrl_init.F) to
519        clean up ctrl_init a little, remove unused variables
520      - ctrl_init: fixed the handling of the start/endrec for obcs-variables
521      - move "call cal_GetMonthsRec" from s/r ctrl_get_gen to s/r ctrl_get_gen_rec
522    
523    checkpoint62u (2011/03/15)
524    o model/src:
525      - for the adjoint, change NonLin-FreeSurf initialisation sequence: fill-in
526        h0Fac from INITIALISE_FIXED and reset hFac to h0Fac in INITIALISE_VARIA ;
527      - in initialise_varia.F (except for ALLOW_DEPTH_CONTROL) remove 2nd call to
528        INI_DEPTHS, INI_MASKS_ETC & INI_LINEAR_PHISURF.
529    o pkg/ctrl/obcs/ecco:
530      - remove obsolete, unused, and partially broken code:
531        ctrl_obcsvol/ctrl_obcsbal/ctrl_volflux and code within
532        ALLOW_CTRL_OBCS_BALANCE
533      - put a stop statement into ecco/cost_obcsvol.F, but also add
534        cost_obcsvol to ecco_ad_diff.list
535    o pkg/ecco: fix counting cost function contributions for obcs (code
536      by Matt M.) and diffkr for diagnostics
537    o pkg/ecco, pkg/ctrl, pkg/grdchk:
538      add cost penalty terms for initial uvel, vvel, eta controls
539      and I/O for prior error files
540    o pkg/mdsio:
541       move mds_check4file.F from eesupp/src to mdsio_check4file.F ; add option
542       (new argument) to check for tiled file in mdsioLocalDir : this fix the
543       restart from pickup_som , pickup_dic (& dic_co2atm) with mdsioLocalDir.
544    o pkg/ctrl:
545     - ctrl_obcsbal.F, ctrl_obcsvol.F: replace last calls of ctrl_getrec by
546       ctrl_get_gen_rec, put a stop statement into ctrl_getrec. Remove
547       unused and superfluous variables
548     - ctrl_get_gen_rec.F: catch the case of xx_genperiod=0.
549    o pkg/ecco
550     - enable adjoint of Stevens OB
551    o pkg/ctrl/ecco/grdchk:
552      - remove global declaration of tmpfldx/yz and tmpfldx/yz2.
553        Fortunately, we do not have any tests for the numerous cpp-flagged
554        option of "obcs as control parameters" so we will never know
555        if this is an improvement (but at least now things compile).
556      - remove an obsolete initialization from ecco_cost_init_barfiles.F
557      - fix some problems within never used ifdefs to make the code compile
558    o pkg/obcs:
559     - Refine Interior mask definition to work with more complex OB (e.g.
560       if OB_Ie < OB_Iw); In case default setting is not sufficient, allows to
561       read in Interior mask from file. Check if Interior mask is consistent
562       with OB list of indices.
563    o pkg/seaice
564     - beginning code for a seaice tracer package,
565       but currently only used for seaice age: SEAICE_AGE
566       SEAICE_num = 4
567       iTracer = 1: area-weighted ice age
568               = 2: volume-weighted ice age
569               = 3, 4: template for one-year vs. multi-year ice
570       data.seaice has new namelist SEAICE_PARM03 for arrays related to
571       SEAICE_num
572    
573    checkpoint62t (2011/03/05)
574    o pkg/obcs:
575     - obcs_apply_uv.F: change to a 2 steps method, first tangential component;
576       then normal component. This ensures that the normal component is set
577       correctly even when it conficts with tangential setting from an other OB.
578       Affects results of test-experiment seaice_obcs: update the output.txt
579    o pkg/obcs:
580     - add code to monitor statistics of dynamical fields at OB.
581     - take OBCS_BALANCE code out of obcs_calc.F into new S/R OBCS_BALANCE_FLOW :
582       - fix to OBCS_BALANCE code (right hFac ; deal with simple OB intersection).
583       - change default: balance the Net inflow through all OB (instead of balancing
584         each OB separately); keep the old method if setting OBC_balanceFacX < 0.
585     - switch on useOBCSbalance in dome experiment: only correct Western OB outflow
586       to match Nortern OB inflow (OBCS_balanceFacN=0).
587    o pkg/seaice:
588     - redefined actual sea ice age to be ICEAGE/HEFF ifdef SEAICE_AGE_VOL
589    o pkg/seaice (seaice_growth v 1.113):
590     - reverting seaice_growth to v 1.111 in order to have code with exact bit
591       compatibility with MITgcm_contrib/ifenty/Fenty_seaice_thermo_code_merge
592       CPP option SEAICE_OCN_MELT_ACT_ON_AREA removed in v 1.112 is reintroduced
593       runtime flag SEAICEareaFormula is kept but is inactive
594    o model/src:
595     - add new param to scale curvilinear grid distance and area when using
596       a different sphere radius from the grid-files.
597     - test/check multi-threads EXCH applied to local variable (cg2d_x)
598    o adjoint:
599     - enable adjoint of Stevens OB
600     - add dummy_in_dynamics to enable extraction of ADJrhoinsitu
601       (a bit delicate because of potentially modified adj. common block structure;
602       current switch is ALLOW_AUTODIFF_MONITOR_DIAG, could be changed later)
603    
604    checkpoint62s (2011/02/15)
605    o pkg/seaice (seaice_growth v 1.112):
606     - introduce SEAICEareaFormula run time parameter, which selects the recipe for
607       computing the ice cover tendency from effective thickness tendencies. Include
608       Ian Fenty's formula.
609     - remove 'undef SEAICE_OCN_MELT_ACT_ON_AREA' which may now be achieved using
610       SEAICEareaFormula.
611     - simplify notations for the various d_HEFF/d_AREA terms.
612    o pkg/gmredi:
613     - add Boundary-Value-Problem bolus transport (Ferrari etal, OM 2010) code
614       from Christopher Wolfe (UCSD); add partial cell factor in vertical derivative;
615       add a verification test-run (front_relax.bvp) to test GM_useBVP.
616    o pkg/seaice (seaice_growth v 1.111):
617     - for SEAICE_DO_OPEN_WATER_GROWTH, replace Gael's implementation with Ian's.
618     - the new SEAICE_DO_OPEN_WATER_MELT allows open-water air-sea heat fluxes to
619       also melt ice.
620    o pkg/seaice:
621     - McPhee formula for Ice-Ocean fluxes (provided by Ian Fenty).
622     - can be used by #define MCPHEE_OCEAN_ICE_HEAT_FLUX in SEAICE_OPTIONS.h
623    o pkg/cheapaml:
624     - from Nico Wienders: New version of this package.
625    o pkg/flt:
626     - add CPP options to prevent floats to re-enter the opposite side of
627       a periodic domain (default: keep periodicity)
628    o pkg/gmredi:
629     - apply exchange to GM_PsiX,GM_PsiY to get valid values near CS-corners
630       (needed for multi-dim advection).
631     - switch on GM Advective form in global_ocean.cs32x15 and update output.txt
632    o model/src:
633     - fix wrong re-setting of addMass array (ALLOW_ADDFLUID) for atmospheric run.
634    o tutorial_tracer_adjsens
635     - extend to NLFS and replace maskC by hFacC
636       (change reference output accordingly)
637    
638    checkpoint62r (2011/01/24)
639    o testreport:
640     - add option -deloutp (-do) to remove output file after successful run
641     - add option -mfile (-mf) for MPI machile-file and for each test-exp,
642       extract exact list of procs from this file ; adjust COMMAND by
643       replacing TR_MFILE & TR_NPROC with local machile-file & Nb of MPI procs.
644    o pkg/ecco: replace old ineffective way of penalizing deviations from
645      first guess (of obcs) with code by Matt Mazloff
646    o pkg/ctrl: add code that allows the use of ALLOW_OBCS?_CONTROL without
647      exf/cal
648      - ctrl_init: fix initialisation (computation of diffrec) for obcs-ctrl
649        and handle case of obcs?period == 0
650        Not affected by these changes: There is still an inconsistency in
651        the computation of start/endrec for the obcs variables for ALLOW_CAL
652        defined (see comment by Menemenlis, 7-Mar-2003)
653      - make S/R ctrl_get_gen_rec return something meaningful even if
654        ALLOW_CAL is not defined
655      - ctrl_getobcs?: simplify code so that it does not need to use
656                       S/R exf_swapfields
657    o testreport:
658       allow to test MPI with different number of processors for each experiment:
659       create file "SIZE.h.mpi" in each build dir.
660       Note: update of "-command" argument not yet implemented.
661    o model/src, pkg/autodiff, pkg/ecco, pkg/seaice:
662      alleviate the need for additional 3D tapes when using
663      the non-inear free surface in the adjoint. This is done
664      by adding an 'update' of hfacc etc. to their current
665      value at the beginning of forward_step.F.
666    o pkg/seaice
667      seaice_lsr: move stress-divergence computations out of outer pseudo-
668      timestepping loop
669    o pkg/obcs/obcs_prescribe_read.F: move 'CALL OBCS_EXTERNAL_FIELDS_LOAD'
670      up, so that the calls of the ctrl_* subroutines are really at the end
671      of the routine.
672    o pkg/gmredi:
673      allow to specify a 2-D horizontal map and a 1-D vertical profil
674      as scaling factor for Isopycnal diffusivity (Redi) and GM diffusivity.
675    o pkg/seaice:
676      move lsr iterations from seaice_dynsolver to seaice_lsr.
677    o pkg/seaice:
678      reduce memory footprint of seaice mutldim advection tapes,
679      by using a 2D tape independent of the generic_advdiff ones,
680      and setting GAD_AREA=1 etc. rather than GAD_AREA=101 etc.

683    o model/src:
684      - check horizontal grid-spacing for unset or zero/negative values.
685      - change AD test hs94.1x64x5 to be truly a 2-D set-up.
686    o pkg/flt:
687      - use (recent) mdsio S/R MDS_READVEC_LOC instead of local FLT_MDSREADVECTOR
688      - precision of input and output files set according to readBinaryPrec
689        and writeBinaryPrec (previously always 64.b), pickup remains at 64 bits.
690      - initial float position from tiled file was not converted to index space
691        (looks like a bug): fixed to make it similar to initial pos. global file.
692    o global_ocean.cs32x15:
693       change SIZE.h of AD set-up to get same tiling as with MPI.
694       Update output_adm, output_adm.thsice (pass@14) & output_adm.seaice (fail@11)
695    o model/src:
696       add flag to control printing of domain fields (bathymetry, hFac ...) in
697       ini_mask_etc (call to plot_fieds_xy*).
698    o pkg/thsice:
699       if useEXF, some forcing fields are not valid in overlap: fixed by computing
700       over the interior only + apply EXCH at the end (like with SEAICE advection).
701    o pkg/mdsio:
702      - add 2 arguments to S/R MDS_PASS_R4/8toRL/S for overlap size of buffer
703        to copy to/from, so that it can be used to replace MDS_PASS_WH_R8toRL/RS.
704      - change barrier call for safe multi-threads access to 3-D shared buffer.
705      - MDS_READ/WRITEVEC_LOC use buffers from MDSIO_BUFF_3D.h (instead of local ones)
706      - replace call to MDS_PASS_WH_R4/8toRL with call to MDS_PASS_R4/8toRL and
707        remove the 4 S/R MDS_PASS_WH_R4/8toRL/S.
708    o pkg/flt:
709      - add fourth-order Runge-Kutta integration
710      - add basic exch2 support (only 1 facet supported so far!)
711    o pkg/mdsio+rw:
712      new S/R to read local (or tile independent) vector (read counterpart of
713       mds_writevec_loc, and front-end write_glvec_rl/rs).
714    o global_ocean.cs32x15: additional input_ad.seaice experiment
715        that uses pkg/seaice rather than pkg/thsice.
716        (using multidim advection for seaice)
717    o towards more F95 syntax for array specification in namelist:
718      - change "data.diagnostics" (data.ptracers was changed before checkpoint62p)
719        of all verification experiments.
720           e.g.:    line: fields(1,3)='ETAN    ','ETANSQ  ',
721          was changed to: fields(1:2,3)='ETAN    ','ETANSQ  ',
722      - finish adding "-DNML_EXTENDED_F77" to DEFINES list in pgf77 and g77 optfiles
723    o global_ocean.cs32x15: additional input.seaice experiment
724        that uses pkg/seaice rather than pkg/thsice.
725    
726    checkpoint62p (2010/12/17)
727    o pkg/thsice: rename (ad tape index) iicekey as ticekey, and move it
728        to THSICE_SIZE.h to avoid conflict with pkg/seaice.
729    o pkg/seaice: add seaice_diffusion.f seaice_map_thsice.f to adjoint.
730        allow for use of multim. advection in seaice adjoint.
731    o pkg/seaice: add diagnostics for snow precipitation and sublimation flux
732      - first attempt to close budgets by taking into account the freshwater
733        flux implied by the sublimation of snow and ice. So far only the
734        volume budget is closed, turn on with soon-to-be-retired-again CPP-Flag
735        SEAICE_ADD_SUBLIMATION_TO_FWBUDGET
736    o eesupp/src:
737      new S/R with new option (NML_EXTENDED_F77) to change array specification
738      from F95 standard to commonly accepted extended F77 form.
739      This would allow to use F95 syntax in namelist (needed with gfortran 4.4.5)
740      and to revert back to the original syntax (with -DNML_EXTENDED_F77)
741      for less tolerant f77 compiler (e.g., pgf77, g77).
742    o globalFiles:
743      commented out in parameter file "data" since it's not safe with MPI
744      (e.g., wrong on aces); keep it if useSingleCpuIO=T (but not doing much
745      in this case); no longer commented out in restart test (tst_2+2).
746    o add adTapeDir to specify a special directory where adjoint tapes are
747      written/read (adread_adwrite.F). adTapeDir is specified in data/PARM05
748      and cannot be used together with mdsioLocalDir.
749    o nesting pkgs:
750      - packages_init_variables : put call to OBCS_INIT_VARIABLES in last position
751      - update Gianmaria's Nesting pkgs (from Contrib/nesting_sannino)
752      - add parameter files + utils dir + output from short run on beagle.
753    o pkg/seaice:
754        fix seaice_growth.F store directives; update results of exp. lab_sea.ad
755    o pkg/seaice: explicitly store tsurfloc in seaice_solve4temp.F to avoid
756      unnecessary copying in adjoint code, requires new parameter NMAX_ITER
757    
758    checkpoint62o (2010/11/25)
759    o pkg/exf:
760      - change CPP option EXF_VERBOSE to run-time logical param exf_verbose.
761    o pkg/seaice:
762      - seaice_ocean_stress: split a loop for better vectorization of the
763        adjoint code
764      - seaice_growth.F: fix bug in conservation of freshwater connected to
765        capping of heff, put contribution into d_HEFFbyNEG
766      - replace irritating parameters SEAICE_latentWater/Ice and SEAICE_sensHeat
767        by something more sensible (parameters that are what their name implies)
768      - change some defaults, so that by default exf-parameters are used for
769        things like rhoAir, cpAir,latent/sensible heat parameters, in order
770        to reproduce the old results, many data.seaice now contain funny values
771        for cpAir and latent heat of sublimation
772    o packages_readparms.F: move exf_readparms up in line so that
773        exf-parameters are visible for other packages (e.g. seaice)
774    o debugMode & debugLevel=2:
775      - differentiate between debugMode & debugLevel=2:
776        debugMode: controls printing of debug messages (sequence of S/R calls).
777        debugLevel: controls printing of algorithm intermediate results and stats.
778      - remove "if debugLevel=2 => debugMode" but keep "debugMode =>  debugLevel=2";
779        => allows to print debug-stats without all sequence of call messages.
780      - switch control of debug print from debugLevel to debugMode in many S/R.
781    o pkg/obcs (obcs-sponge):
782        fix bug that was introduced on Oct 25 (in dynamics.F v1.151): put back the
783        call to OBCS_PRESCRIBE_EXCHANGES (need to exch gU,gV when using obcs-sponge)
784    o pkg/generic_advdiff:
785      - record overlap minimum size for each advection scheme;
786      - refine criteria on overlap minimum size;
787      - check and stop (in gad_check) if overlap size is too small.
788    o pkg/obcs:
789      - with ptracers: remove multiple calls to obcs_apply_ptracer (only done
790        once, in ptracers_implicit.F)
791      - with seaice: remove test on empty file name in obcs_apply_seaice (always
792        apply OB values when tile has OB)
793    o model/src, coriolis setting:
794      - integer parameter "selectCoriMap" (=0,1,2) replaces 3 logical
795        useConstantF, useBetaPlaneF, useSphereF ; can now read coriolis from
796        files (selectCoriMap=3) with any grid.
797      - add parameter "fPrime" for constant second Coriolis coeff (default=0).
798    o pkg/seaice/seaice_growth.F:
799        a few cosmetic changes that reduce the number of lines of code
800    o pkg/obcs: add boundary conditions following Stevens (1990)
801      - the code follows old MOM/NAOSIM code
802      - so far it is only implemented for the eastern and western boundaries
803        and NOT for pTracers
804    o pkg/rbcs:
805      - replace rbcsInIter by rbcsForcingOffset, the time in seconds at the
806        beginning of the first rbcs forcing period.
807      - add option rbcsSingleTimeFiles that makes rbcs read forcing data like the
808        offline package, i.e., one file per time, labeled by iteration number;
809        deltaTrbcs sets the timestep with which the data was generated;
810        rbcsIter0 is the forcing iteration corresponding to rbcsForcingOffset.
811      - rbcsForcingCycle=0 makes forcing non-cyclic.
812      - make arithmetic safe for negative times and odd forcing periods.
813    
814    checkpoint62n (2010/11/09)
815    o pkg/seaice:
816        fix masking in free-drift S/R ; update results of exp. lab_sea.fd
817    o pkg/obcs:
818       New S/R to copy tracer value from the OB location to narrow band region
819        (width = same as overlap) beyond the OB: preserve OB value (needed for
820        high-order scheme) which were overwritten by EXCH call if in overlap
821        region. Applied to theta, salt, ptracer and advected seaice variables.
822       With seaice: use maskInC in similar way as in gad_advection.F,
823        in seaice_advection.F and advect.F.
824       Update output of experiment seaice_obcs and change exp4 to test OBCS with
825        4th order Adv.Scheme. for pasive salt and ptracer.
826    o tools/genmake2:
827      - when looking for an optfile (not specified), only search for Fortran compiler
828        (remove sym-link test + setting of CPP + makedepend check + C-compiler check)
829      - in get_fortran_c_namemangling: use "$CC $CFLAG" to compile C test programm
830        (instead of "$MAKE genmake_test.o" since an existing Makefile can be wrong)
831      - set default for CPP to "cpp -traditional -P" (was the case without specifying
832        an optfile, but otherwise default was just "cpp".
833      - comment out PLATFORM=$p_PLATFORM (no idea where p_PLATFORM comes from)
834      - when "CC" is not set in the optfile, look for possible C compiler
835        (instead of just setting CC=cc)
836      - put back version v.169 modif (from 2008/02/15), was dropped in v.173 changes:
837        => add a ".F" to ".o" rule for source files with no "#include" (such as
838           port_rand.F); otherwise, default ignores FOPTIM and just uses FFLAGS.
839      - move gfortran before g77 in list of possible Fortran compiler (consistent
840        with reference compiler switch from g77 to gfortran)
841    o pkg/seaice:
842      o remove SEAICE_OLD_AND_BAD_DISCRETIZATION-code, add a test to
843        seaice_check that stops the model, when the CPP flag is used.
844      o seaice_growth.F: make capping of ice volume conserving by returning the
845        capped ice as freshwater to EmPmR. This does not change the verification
846        experiments but will change runs where the capping is acutally active
847    o change reference platform+compiler from faulks+g77 to baudelaire+gfortran
848      (except the 2 fizhi test exp.); update output of exp.: bottom_ctrl_5x5,
849         global_ocean.cs32x15 (icedyn, thsice, AD thsice), global_ocean_ebm (AD),
850         lab_sea (fd, hb87, salt_plume), MLAdjust (3/5) and vermix (dd)
851    o tools/genmake2:
852      - merge genmake_warnings & genmake_errors into 1 log file: "genmake.log")
853      - change DUMPSTATE default to false (can use "-ds" option to switch it to T)
854      - clean previous genmake log files before anything else.
855      - change Makefile to remove testreport log files (*.tr_log) and genmake log
856        files only with "CLEAN" target (instead of "Clean");
857    o pkg/generic_advdiff:
858      Change OBCS in multiDim advection (gad_advection.F):
859       Use maskInC to prevent intermediate update of tracer-field in OB regions,
860       thus keeping current-time-step OB values; and remove the call to OBCS_APPLY
861       which were applying future time-step OB values.
862      This way, all explicit calculations use current-time-step OB values
863       (simpler and more consistent).
864      Affects results when set-up uses time-varying OBC and multi-dim advection;
865       update output of experiment seaice_obcs.
866    o pkg/seaice:
867      move OPTIONS (formerly locally defined) to SEAICE_OPTIONS.h:
868       this includes SEAICE_GROWTH_LEGACY (+ SEAICE_DO_OPEN_WATER_GROWTH &
869         SEAICE_OCN_MELT_ACT_ON_AREA ) and SEAICE_SOLVE4TEMP_LEGACY.
870      Default (pkg/seaice/SEAICE_OPTIONS.h) is to define SEAICE_SOLVE4TEMP_LEGACY
871       but leave SEAICE_GROWTH_LEGACY undef ; For now, keep verification exp
872       unchanged (SEAICE_GROWTH_LEGACY defined in */code*/SEAICE_OPTIONS.h)
873    o pkg aim (2010/10/26):
874      - Introduce ALLOW_INSOLATION, moving toward a more general incoming solar radiation
875        formulation with obliquity, eccentricity, ... as run-time parameters,
876      - Introduce diagnostics for top-of-the-atmaophere incoming solar radiation and
877        upward shortwave radition at the surface (all-sky and clear-sky).
878    o pkg/obcs:
879      - writing sections with globalFiles=T does not work: switch to tiled-files
880        when writing sections for OBCS (change pkg/rw/write_rec.F accordingly).
881      - fix index bug (OB_Ie -> OB_Iw_) in obcs_apply_uvice.F
882      - apply OBCS_SEAICE_COMPUTE_UVICE to both uice and vice at all obcs
883    
884    checkpoint62m (2010/10/21)
885    o pkg/seaice: vectorize seaice_solve4temp.F
886      - move iterations loops outside of i/j-loops
887      - requires 2D arrays for TB and effConduct
888      - add 2D iceOrNot to replace HICE_ACTUAL.GT.0, as HICE_ACTUAL is
889        modified in this routine
890      - a little bit of clean up, adjusting indentation, etc.
891      - replaced a few TEN**a by exp(a*log(10.)) in new code for better
892        performance and '**TWO' by '**2' (because TWO is a float),
893        replaced ONE, ZERO
894    o eesupp/src:
895       fix flow dir for exch1_z_RX_cube, exch1_uv_RX_cube & exch1_bg_RX_cube
896    o pkg/seaice/seaice_growth.F
897      Revision 1.89 of seaice_growth.F completes the overall october 2010 revision and
898      merging process. The merged routine has two branches, and one activates the 'evolution'
899      branch by setting SEAICE_GROWTH_LEGACY to undef (at the top of the routine for now).
900      In summary, here is what the '10/10 revision' did consist of
901        part 1: seaice_growth.F revisions 1.71 to 1.75
902          - Preliminary seaice_growth.F clean-up, keeping test results strictly unchanged.
903            The emphasis here was on improving readability (e.g. by trying to use meaningful
904            variable names) and modularity (e.g. by adding arrays to store heff etc. updates).
905        part 1.5:
906          - revising the lab_sea experiment to make it a more useful (i.e. stable
907            and representative of an actual model run). This was done by generating a
908            (winter) pickup to start from, switching back the main experiment dynamic
909            solver from evp to lsr, having one of the experiments use the free drift solution.
910        part 2: seaice_growth.F revisions 1.76 to 1.85
911          - Sorting out hard-coded constants that prevented heat and fresh water conservation.
912          - Sorting out the various fields units and sign (set early on and reset at the end)
913            to avoid numerous scalings/re-scalings. By v1.85 the basic unit for ice, heat and
914            fresh water stock is 'effective ice meters', and >0 implies more ice/snow.
915          - Using tendency terms arrays (d_HEFF* etc.) to alleviate remaining code locks,
916            and simplifying logical expressions to further improve readibility.
917        part 3: seaice_growth.F revisions 1.86 to 1.89
918          - Re-organize the blocks of code more logically.
919          - Merging the '_if.F' pieces that add something new.
920    o pkg/thsice:
921      - vectorize thsice_solve4temp and thsice_get_exf.
922        Problem: thsice_solve4temp has an unvectorizable statement that
923        might also be problematic for TAF
924      - thsice_get_exf: add the ALLOW_BULK_LARGEYEAGER04 CPP-flag. This
925        does not change the verifcation experiment, but will change all
926        experiments that have this flag undefined (not tested in verification);
927        a little reorganization to save a few 2D fields and recomputations
928      - 1st step of revisiting thsice adjoint (major recomp. sorted out)
929      - 2nd step:  fix some store dirs
930        o seems to work somewhat, i.e. using ifort but not g77
931        o likely cause are incomplete init. or recomputation
932        o start verification/global_ocean.cs32x15/input_ad.thsice
933    o pkg/obcs: add support for exch2
934      - the position of the boundary and prescribed values are specified using
935        a global domain with exch2 facets stacked
936        - in x for N,S boundaries (like W2_mapIO=-1)
937        - in y for E,W boundaries (so E,W boundaries do not overlap)
938    o pkg/mdsio: add support for writing global sections with exch2
939        file layout is as for obcs described above:
940        - for x-z sections, facets are stacked in x (like W2_mapIO=-1)
941        - for y-z sections, facets are stacked in y
942    o pkg/thsice:
943       - change a few routines for better vectorization: thsice_albedo.F,
944         thsice_step_temp.F, and in thsice_calc_thickn.F. Results are
945         not affected, but in particular the latter routine has changed
946         dramatically (not necessarily easier to read now).
947       - re-arrange calculation in THSICE_SOLVE4TEMP: move outside of i,j loops
948       iteration loop and call to S/R THSICE_GET_BULKF & THSICE_GET_EXF.
949    o verification/lab_sea:
950      - overhaul of the forward model experiments. The main motivation
951        for this revision is that lab_sea has proven quite fragile (when
952        changing the sea-ice code, and switching platforms) to a point
953        when failures were very hard to attribute to specific code problems.
954      - the suspected reason for this fragility is noise amplification by evp so,
955        to start with, we decided to replace evp with lsr in the main experiment.
956      - the input.lsr experiment thus became obsolete and was removed.
957      - it was replaced with the input.fd experiment that uses an
958        analytical "free drift" solution as the ice velocity field.
959      - Taken together, input (lsr), input.fd (free drift) and input.hb87 (evp)
960        will hopefully allow us to discriminate problems due to dynamic solvers
961        from problems due to the thermodynamic code. input.salt_plume (lsr) allows
962        us to test additional options, along with the salt plume package.
963      - Finally a pickup was generated (at the end of a one year run) to
964        make the tests more representative of an actual model run. Previously
965        the tests starting point was a 1m thickness of ice everywhere.
966    o pkg/seaice:
967      - introducing S\R seaice_freedrift.F that compute the
968        analytical solution to an approximate ice momentum
969        equation (i.e. the simple stress/coriolis balance).
970      - define SEAICE_ALLOW_FREEDRIFT to trigger the computation
971        of the free drift velocity field, and enable its use.
972        To actually use the free drift solution as the model ice
973        velocity field set SEAICEuseFREEDRIFT to .TRUE. in data.seaice.
974    o move "useOASIS" from PARAMS.h to EEPARAMS.h and read it from "eedata"
975    
976    checkpoint62l (2010/10/04)
977    o pkg/seaice:
978      -fix the USE_ORIGINAL_SBI version (for variable freezing point);
979      -use "celsius2K" in SEAICE_VARIABLE_FREEZING_POINT and in new
980       version (with USE_ORIGINAL_SBI undef);
981    o add hooks for new packages OASIS, the package will follow
982      (hooks exclude the seaice pkg for now)
983    o pkg/autodiff: ALLOW_AUTODIFF_WHTAPEIO
984      Option to use mdsio_read_whalos.F/mdsio_write_whalos.F,
985      rather than mdsio_readvector.F/mdsio_writevector.F, within
986      adread_adwrite.F to read/write adjoint-related tapes to disk.
987    o eesupp and pkg/mdsio: ALLOW_WHIO
988      Option to write/read 2D fields to files including tiles halos.
989      The main purpose is for adjoint related "tape I/O".
990      The secondary purpose is for debugging phases.
991      A word on those rather specifically intended purposes.
992      The code was meant to be stripped down to the bare minimum.
993      Typically, there is a unique and basic mapping to the global
994      buffer (tile by tile, then proc by proc, then level by level), and
995      byteswaps and meta-files are omitted. Indeed the (*_WH*) code is not
996      meant to generate user friendly outputs of various shapes and forms.
997      Rather it is intended, for the knowledgeabale developers,
998      to be largely independent of the many mdsio options, to allow
999      outputs of tiles+halos in debugging phases and in adjoint runs,
1000      and to allow some flexibility in tuning (adoint) I/O depending on each
1001      file system behavior. With regard to tuning, most of the potential knobs
1002      (to leave files open, to allocate the I/O indep. of usesinglecpuio,
1003      to specify directories, to specify the typical size of I/O calls, etc.)
1004      are not yet included, and will be added if they prove useful.
1005    o pkg/seaice:
1006       fix uninitialised arrays in USE_ORIGINAL_SBI version of seaice_solve4temp.F
1007    o pkg/seaice:
1008       new S/R seaice_solve4temp.F: this is the merged version of Ian Fenty
1009       code (seaice_budget_ice_if.F) which enable to recover old standard
