5      ==============================      ==============================
6    
7    o tools/build_options:
8      - after merging some MPI and/or multi-threads specific optfiles so that
9        the modified default optfile support both built (using genmake2 -mpi
10        for the MPI built, using genmake2 -omp for OpenMP built),
11        move now obsolete optfiles to tools/build_options/unsupported/
12       (add copy of email sent to support list in doc/optfiles_changes.txt)
13    
14    checkpoint63c (2011/09/28)
15    o pkg/ebm:
16      - fix ebm_zonalmean.F for several procs in Ydir (nPy > 1); update output of
17        test exp. global_ocean_ebm (affects machine truncation, 12 digits for cg2d)
18    o pkg/seaice (SItracer pickup)
19    * Simple code for pickup of SItracer fields (#define ALLOW_SITRACER)
20      To be done:
21      - thorough testing of missing fields in S/R seaice_read_pickup
22      - thorough matching between generic tracers and specific fields used
23        (e.g. volume-weighted age, area-weighted age, salinity, ...)
24    o pkg/grdchk:
25      - all procs calculate and print finite-difference gradient (for testreport)
26      - change description output used by testreport;
27      - AD testing: also compare and report Finite-difference gradient;
28        => update all output_adm*.txt
29    o test exp. global_ocean_ebm:
30      - switch back useRealFreshWaterFlux (no problem anymore with run-off);
31        and turn on exactConserve; update (fwd) output.
32    o pkg/seaice (LSR):
33      - print to STDOUT number of solver iterations at SEAICE_monFreq interval.
34      - modify solver to deal cleanly with u/v switch at face edges (CS-grid):
35        * identical results with non-CS topology (but save up to half of EXCH calls)
36        * no much changes in cs-32 verification tests since no ice at face edges
37         (differences due to convergence criteria, since nb of iterations changed)
38        * expect some differences on lat-lon-cap grid.
39        update FWD results of global_ocean.cs32x15 test exp. (icedyn & seaice)
40    o pkg/exch2:
41      - add new CPP option to disable Cumul-Sum matrix (to save storage when using
42        many tiles); until alternative coding is added, just add a stop.
43    o pkg/kpp:
44      - move ptracer/salt correction to KPP diffusivity from calc_3d_diffusivity.F
45        to S/R KPP_CALC_DIFF_PTR (+ add tracer-index to argument list).
46    o optfiles:
47      - merged few MPI specific (*+mpi*) and multi-threads specific (*+mth) optfiles
48        into corresponding standard one, which now support different build:
49        (when using "genmake2 -mpi" for MPI built, "genmake2 -omp" for OpenMP built)
50      - add "darwin_amd64_gfortran" optfile (initially from Constantinos, tested by Gael)
51    o pkg/obcs (seaice):
52      - add missing EXCH for uIce,vIce after applying OBCS;
53      - remove S/R EXF_SWAPFFIELDS_X/Y , disable S/R EXF_SET_OBCS_X/Y by adding
54        argument = number of levels to S/R EXF_SWAPFFIELDS_XZ/YZ and S/R
55        EXF_SET_OBCS_XZ/YZ ; update obcs_exf_load.F;
56      - fix EXF_SET_OBCS_XZ/YZ for multi-threaded (assuming loaded arrays are shared)
57      - verification exp. seaice_obcs: split domain in 2 tiles ; add SIZE.h_mpi
58        and eedata.mth for MPI and mutlti-threaded testing.
59    o pkg/flt:
60      - make FLT EXCH working with multi-threads (and MPI + multi-threads);
61      - use buffer for floats IO (trajectories & profiles); size set in FLT_SIZE.h;
62      - fix pickup and trajectories + profiles output with multi-threads;
63      - add parameter to select group of fields to write along trajectory and
64        profile (default unchanged);
65      - only call PORT_RAND* function when flt_noise <> 0;
66      - add multi-threaded test for verification exp. flt_example.
67    o eesupp/src:
68      - fix S/R ALL_PROC_DIE for MPI+multi-threads.
69      - USE_OMP_THREADING: check that number of threads (from eedata) matches
70        actual number (from env.var. setting).
71    o pkg/ebm:
72      - fix multi-threading in ebm_area_t.F ; clean-up EBM.h header file.
73      - add multi-threaded test for verification exp. global_ocean_ebm
74    
75    checkpoint63b (2011/08/29)
76    o pkg/ebm:
77      - fix sign of runoff;
78      - update directly forcing fields (Qnet,EmPmR) to use standard
79        external_forcing_surf.F (remove ebm_forcing_surf.F);
80      - avoid loading forcing fields a 2nd time (1rst time from ini_forcing.F);
81      - set either tauThetaClimRelax (in data) or tauThetaZonRelax (in data.ebm)
82        and apply relaxation towards corresponding SST field (2-D map or ZonAver).
83      - update global_ocean_ebm parameters file data and update output (fwd+ad).
84    o verification/matrix_example:
85      - split domain in 8 tiles (2x4); add SIZE.h_mpi and eedata.mth for
86        MPI and mutlti-threaded testing.
87    o pkg/matrix:
88      - change name of S/R MATRIX_INIT to S/R MATRIX_INIT_VARIA ;
89      - fix for multi-tiles (add bi,bj indices to exp/impMatrixCounter);
90      - fix for multi-threaded (remove DATA statement);
91      - use standard DIFFERENT_MULTIPLE function;
92      - add MATRIX_OPTIONS.h
93    o verification/matrix_example:
94       To allow to split the domain in several tiles, change the domain size
95        from 31x31 to 32x32 by adding 1 row (on Southern side) + 1 column (on
96        Western side) of land points.
97    o (*_)write_pickup:
98      - fix few bugs in mypackage_read/write_pickup.F
99      - in MDS_WR_METAFILES calls, replace "myTime" by a local copy into
100        array of length 1 (was caught by compiler syntax-check).
101    o pkg/diagnostics (velocity potential solver):
102      - fix initialisation of main diagonal matrix (for overlap values)
103    o tools/build_options:
104      - towards single optfile for MPI and non-MPI built: merge few +mpi optfile
105        into previously non MPI one (linux_am64 pgf77,open64,pathf90,ifort11)
106      - linux_amd64_gfortran: merge +mpi_generic version into standard optfile:
107        * move IEEE flags to DEVEL section; take IEEE flags from +mpi_generic ;
108        * FAST case: for now, keep -O3 with ini_masks_etc.F in NOOPTFILES list;
109        and use "-devel" testreport option for standard testing on baudelaire.
110    o pkg/grdchk:
111      - Assume that all gradient-check position are within the same tile
112        corresponding to global indices (iGloTile,jGloTile) and that
113        positions (i,j indices or nbeg) are local to this tile;
114      - set tile local-indices and proc. number according to tile global-indices;
115      - remove grdchkwhichproc from namelist (retired param);
116      - send adjoint gradient to all procs so that all procs print it to STDOUT;
117      - switch on MPI test for global_ocean.90x40x15 AD test experiment.
118    o adding package bbl (Bottom Boundary Layer)
119      description in MITgcm/pkg/bbl/bbl_description.tex
120      example/test experiment in MITgcm_contrib/bbl
121    o adjoint verifications
122      - changed 5 experiments to multi-tiles
123        * global_ocean.90x40x15
124        * obcs_ctrl
125        * offline_exf_seaice
126        * tutorial_dic_adjoffline
127        * tutorial_tracer_adjsens
128        changed reference output for those that crossed tile boundaries
129        (changed choices of gradient check positions)
130      - with same tiling, switch on MPI test for the last 4 (add SIZE.h_mpi)
131      - temporary bug fix in grdchk_loc.F for obcs
132    o genmake2 & testreport
133      - add target "obj" (just for OBJFILES files) to Makefile;
134      - add option to specify FEXTRAFLAGS on command line.
135    o pkg/mypackage:
136      - remove bi,bj arguments from argument list of S/R MYPACKAGE_CALC_RHS
137    
138    checkpoint63a (2011/08/02)
139    o pkg/diagnostics (velocity potential):
140      - fix velocity-potential calculation when using OBCS: balance net inflow
141        at each level (new S/R OBCS_DIAG_BALANCE).
142      - fix some of the problems with OBCS in stream-function calculation.
143    o pkg/exf/exf_readparms.F
144      - make treatment of optional namelists (EXF_NML_04, EXF_NML_SGRUNOFF,
145        EXF_NML_OBCS) more consistent, so that you need not have these lists
146        in data.exf when they are not used.
147    o optim/optim_readdata.F:
148      - add some output about obcs variables that might help debugging
149      - add a check about nvarlength
150    o pkg/ctrl: once again, fix computation of endrec in s/r ctrl_init_rec
151    o pkg/diagnostics (velocity potential):
152      - fix mask for OBCS (still problems in stream-function with OBCS);
153      - add specific parameter (default = main code CG2D params) for solver;
154      - in case of poor convergence, use solution corresponding to lowest residual.
155    o pkg/seaice/seaice_growth.F: small changes that permit vectorizable
156      adjoint code. In general statements like tmpscal=fld(i,j) are problematic
157      and should be avoided where possible.
158    o model/src (rStar):
159      - include r* effect on reference-state (PhiRef) in totPhiHyd
160        (so that it's really the potential anomaly at the cell center);
161        affect solution only if z* with full pressure in EOS.
162      - test-exp global_ocean.90x40x15: reduce viscA4 (was not stable) and
163        update output (because of z* in totPhiHyd and viscA4 changes);
164      - keep the previous diagnostics as "PHIHYDcR" (closer to potential anomaly
165        @ constant r) until interpolation at constant r is implemented.
166    o pkg/diagnostics
167      - fix RCENTER diagnostics in case cell center is not at interface middle
168    o add code for TEOS-10 (www.teos-10.org, McDougall et al. 2011). Use
169      this eos with eosType = 'TEOS10', in data (PARM01). This eos implies
170      that THETA and SALT are "conservative temperature" and "absolute
171      salinity"
172    o pkg/ctrl
173      - fix computation of endrec in s/r ctrl_init_rec
174      - ctrl_pack/unpack_*: remove unused variables and some obsolete code
175    o pkg/seaice/seaice_growth.F
176      - fix recomputation with FENTY_AREA_EXPANSION_CONTRACTION code,
177        remove then obsolete STORE directives
178      - fix STORE directives for tice and tices, so that only the
179        appropriate part of the fields are stored (and not the entire
180        field); update global_ocean.cs32x15.seaice AD output.
181      - cosmetic changes: adjust CPP flags and indentation for better
182        legibilty
183    o pkg/autodiff: add mnc-output of adBottomDragFld (code contributed by
184      Chris Wilson)
185    o pkg/gmredi:
186       Add Sub-Meso Eddies parameterisation from Baylor (for now, disabled with TAF),
187       and test it in verification exp. "front_relax.bvp" (update output.bvp.txt)
188    
189    checkpoint63  (2011/07/11)
190    o pkg/exch2:
191     - rename+move: nTiles in W2_EXCH2_PARAMS.h --> exch2_nTiles in W2_EXCH2_TOPOLOGY.h
192     - exch2 version of Cumul-Sum routine: S/R W2_SET_MAP_CUMSUM set up the
193       (2*nTiles)x(nTiles) Cumul-Sum matrix and Master Proc collects all tiles X,Y
194       increments, calculates Cumul-Sum @ tile origin and sends results to each tile.
195    o pkg/diagnostics:
196     - deal with pairs of post-processed diags which are computed together; in
197       particular, re-order list of diags within 1 file to save 2nd computation.
198     - add S/R to compute velocity stream-function (called after velocity-potential
199       calculation) from divergence free transport -> new diagnostics "PsiVEL".
200     - add parameter to select grid-point location where PsiVEL == 0.
201    o eesupp/src:
202       new S/R to calculate cumulated sum on tiled array, corner grid-cell location
203       (specific S/R needed with exch2 topology - for now, just print an error msg)
204    o pkg/shelfice
205     - Implement friction velocity-dependent transfer coefficients following
206       Holland and Jenkins, JPO, 1999
207       Original code by M. Losch with small modifs.
208       Enable with CPP option SHI_ALLOW_GAMMAFRICT
209       and runtime flag SHELFICEuseGammaFrict
210    o verification lab_sea & global_ocean.cs32x15:
211     - use tools/xmakedepend (instead of cyrus_makedepend, in genmake_local):
212       does not miss some dependencies (but is slower) and also works with many files
213       (default makedepend limitation for AD built).
214     - use cyrus_makedepend in adjustment.128x64x1 (so that it still tested).
215    o pkg/diagnostics:
216     - add run-time parameter "useMissingValue" (def=False) to fill land-point
217        (i.e., where mask=0) with MissingValue ; used only in MNC output file.
218       This replaces CPP-option DIAGNOSTICS_MISSING_VALUE.
219     - Extend the use of "missing_value" setting from data.diagnostics for the case
220       of counter-diagnostics (where fraction-weight is zero). This applies both to
221       MNC and MDS output files.
222    o pkg/seaice/seaice_growth.F:
223      - add 'a priori' cap of latent heat flux based on actual mass considerations
224        when SEAICE_ADD_SUBLIMATION_TO_FWBUDGET is used in conjunction with the
225        non-legacy seaice_solve4temp.
226      - add diagnostic of the residual sublimation freshwater flux (the freshwater
227        flux taken from the ocean if the total actual latent heat fluxes exceed
228        the maximum)
229      - remove the CPP switch around the *_FWbySublim unit change and move diagnostic
230       fill for SIatmQnt, SIfwSubl, SIatmFW to the end of seaice_growth.F.
231      - add diagnostic of the actual sublimation freshwater flux (that is 0. ifndef
232       SEAICE_ADD_SUBLIMATION_TO_FWBUDGET) and of the latent heat flux (evap+sublim).
233      - bug fix : frWtrAtm needs a_FWbySublim ifdef SEAICE_ADD_SUBLIMATION_TO_FWBUDGET.
234      - bug fix : missing part to Martin's r_FWbySublim pathological case fix.
235    o verification 1D_ocean_ice_column:
236       made model domain truly 1x1x23 instead of 5x5x23 with only center cell (3,3,:) wet
237       update results
238    o pkg/diagnostics:
239     - Implement setting of "Post-Processed" diagnostics (corresponding to gdiag(5)='P')
240       which are not filled-up but computed from other diags ; In this case, the mate
241       diag points to the primary (filled-up) diag to used for post processing.
242     - Update Velocity-potential computation using post-processed diag framework.
243     ==> Change the ordering of fields and time-periods in MDS output file
244       when using periodic averaging: now writes one time record with the full set
245       of fields for this time period, then the next time reccord (it used to be
246       one field with the full set of time records then the next field).
247         Note: this is now similar to NetCDF (MNC) output file. <==
248    
249    checkpoint62z (2011/06/21)
250    o adjoint monitor:
251     - Add adjoint monitor output for packages exf, seaice
252       and update relevant testreport output
253    o pkg/seaice:
254     - re-order diags inits so that they appear in order in available_diagnostics.log
255     - added diags: hsnow thermo. rates of change, area preceeding ridiging process,
256       area/heff/hsnow preceeding thermodynamic growth/melt.
257     - modified diag: SIdA; output actual effect, as the description states.
258     - modified description: SIqneti, SIqneto, SIuheff, SIvheff, SIdAb*, HSNOW.
259     - retired redundant diags: SIyneg, SIfice, SIsnwice, SIthdgrh.
260       (SIyneg->SIdHbOCN; SIfice->SIdHbATC; SIsnwice->SIdHbFLO;
261        and SIthdgrh->SIdHbOCN+SIdHbATC+SIdHbATO)
262     - modified diags (2) : switch all SIdA*, SIdH*, SIdS* from delta to rates.
263     - added diagnostics for seaice generic tracers (SItr*).
264     - added SItrUnit and SItrNameLong run time param (for SItr* diags).
265     - in diag names, replaced 'PrTh' abbrev. of 'preceeding thermo' with 'PT'.
266     I. Fenty: 18-Jun-2011:
267     Minor changes to seaice package:
268     1) Retired old variables (A22, SEAICE_lhsublim, areaMax, areaMin, hiceMin) and
269        added some new ones (SEAICE_area_reg, SEAICE_hice_reg, SEAICE_area_floor)
270       - Differentiated "regularization variables" from "floor variables"
271        * areaMin became SEAICE_area_reg (old A22) and SEAICE_area_floor
272        * hiceMin became SEAICE_hice_reg (old hiceMin)
273          (with _reg meaning regularization variable)
274       - SEAICE_lhSublim becomes lhSublim, the sum of SEAICE_lhEvap and SEAICE_lhFusion
275        so as to ensure energy conservation when going between phases
276      - A22 was not used anywhere
277     2) Changed regularization procedure for heffActual and hsnowActual to ensure
278        well-boundedness and smooth adjoint in seaice_growth.F
279     3) Fixed a bug where seaice_solve4temp would not recognize ice-free grid cells
280        because the old regularization always set heffActual >= 0.05 cm
281     4) Changed the model so that the default behavior is to put a small (10^-5) "floor"
282        on AREA when HEFF > 0.
283      - went from requiring ALLOW_PRECLUDE_INFINITESIMAL_AREA to be defined to
284        requiring that DISABLE_AREA_FLOOR *not* be defined
285     Affected verifications:
286      - 1D_ocean_ice_column (output.txt output_adm.txt)
287      - global_ocean.cs32x15 (output.seaice.txt output_adm.seaice.txt)
288    o pkg/diagnostics:
289      - move MNC code from diagnostics_out.F into new diagnostics_mnc_out.F (2 S/R).
290      - rename S/R GETDIAG to DIAGNOSTICS_GET_DIAG and change type of 1rst argument
291        (was _RL, now integer) with option = 0 to retrieve all levels.
292      - add pieces of code to compute velocity potential at each level (new diagnostics
293        PhiVEL, works only when UVELMASS & VVELMASS are also turned on);
294        for now, using same params as CG2D (target-resisual, max Nb of iter ...).
295      - fix few issues with counter diagnostics in diagnostics_setdiag.F &
296        diagstats_setdiag.F (if diagnostic counter is itself a counter diag)
297        and in diagnostics_fract_fill.F (do not need a valid pointer for the
298        diagnostics counter-mate); check that definition of counter-diagnostic
299        includes a valid counter-mate (in diagnostics_set_levels.F).
300    o model/src (rStar):
301      - add rStar scaling factor in diags_phi_hyd.F (similar to calc_grad_phi_hyd.F);
302        affect solution only if z* with full pressure in EOS;
303        update output of test-exp global_ocean.90x40x15.
304    o pkg/seaice:
305      - introduce siEps=1e-5 parameter
306      - use areaMax in AREA update (part 4), consistent with ridging step (part 2.5).
307      - re-organize SEAICE_ADD_SUBLIMATION_TO_FWBUDGET code.
308      - introduce ALLOW_SITRACER and seaice_tracer_phys.F to handle generic seaice tracer.
309        For now it covers, and was tested for, ice salinity and age (attached to HEFF),
310        as well as ice cover age and ridging index (attached to AREA).
311        For now the run time parameters (in data.seaice/SEAICE_PARM03) are
312        SItrName (e.g. 'age') and SItrMate ('HEFF', which is the default, or 'AREA').
313        Up to SItrMaxNum=3 tracers can be used simultaneously.
314    o pkg/salt_plume:
315      -introduce SPsalFRAC run time parameter that sets the fraction of the
316       salt by-product of ice growth (SPsalFRAC*(1-SIsalFRAC)*salt typically)
317       that gets vertically redistributed (fluxed down) by pkg/salt_plume.
318    o model debug options:
319      - Switch reading of debugMode from S/R INI_PARMS (parameter file "data", stored
320        in PARAMS.h) to S/R EESET_PARMS (parameter file "eedata", stored in EEPARAMS.h).
321      - Refine debug-msg printing selection (3 new levels):
322        debugMode  : controls printing of debug messages (sequence of S/R calls).
323        debugLevel : controls printing of algorithm-relevant auxiliary/debug messages
324         debLevZero =  0 ; /* level of disabled aux. msg printing */
325         debLevA =  1 ; /* level of minimum  aux. msg printing */
326         debLevB =  2 ; /* level of low aux. print (report read-file opening)*/
327         debLevC =  3 ; /* level of moderate debug prt (most pkgs debug msg) */
328         debLevD =  4 ; /* level of enhanced debug prt (add DEBUG_STATS prt) */
329         debLevE =  5 ; /* level of extensive debug printing */
330        New debugLevel default: with default debugMode value (=F),
331          = 2 (debLevB) or = 1 (debLevA) in case ALLOW_AUTODIFF is defined.;
332          and if debugMode=T, default debugLevel = 4 (debLevD).
333        Relation with previous settings:
334         debLevB (=2) corresponds to former debLevA (=1)
335         debLevD (=4) corresponds to former debLevB (=2)
336        Note:
337         a) if debugLevel=0, skip WRITE_GRID call when nIter0 > 0 (same as before);
338         b) default debugLevel=1 is convenient in AD runs (avoid many file opening msgs);
339            to recover previous default, set debugLevel=2 (e.g. AD-test hs94.1x64x5)
340      - Add new parameter (printResidualFreq, read from PARM02 namelist) to print
341        detailed CG solvers convergence; off (=0) by default, except if debugLevel=5.
342    o pkg/obcs:
343      - change OBCSfixTopo default from True to False (should not change the results);
344        keep OBCSfixTopo=T in verification-exp. seaice_obcs.
345    o pkg/thsice:
346      - fix bug in thsice_calc_thickn.F (was introduced in version 1.18) in
347        2nd layer seaice sublimation (unlikely to happen)
348      - use Interior mask for OBCS in thsice_advection.F (similar to what is
349        done in gad_advection & seaice_advection).
350    o adjoint:
351      bug fix spotted by Gael Forget:
352      seaice_advection and thsice_advection still had
353      legacy CPP options to avoid CS corner updates for adjoint
354    o pkg/seaice:
355      => Change some of the defaults (2011/05/29):
356         - change SEAICEuseFluxForm default (from False to True)
357         - change DIFF1 default (from 0.004 m/s to 0. m/s)
358         And print warnings if DIFF1 is not set in data.seaice and centered
359          avection scheme is used without any diffusion.
360      also:
361      - fix seaice_diffusion calls in default AdvScheme part of seaice_advdiff.F;
362      - set SEAICEdiffKh[] default in the same way as SEAICEadvSch[]
363      - stop if DIFF1<>0 with SEAICEadvScheme <> 2, if DIFF1<>0 with any
364        other non-zero SEAICEdiffKh[] diffusivity, if SEAICEadvSalt=T with
365        #undef SEAICE_VARIABLE_SALINITY, if SEAICEadvAge=T with #undef SEAICE_AGE.
366      update results of test exp.:
367         lab_sea: output.fd (switch to AdvScheme=33 with diffKh=20)
368             output.hb87, output_adm.evp (SEAICEuseFluxForm=T and diffKh=200)
369             output_adm.noseaicedyn (SEAICEuseFluxForm=T)
370         offline_exf_seaice: output.seaicetd, output_adm (SEAICEuseFluxForm=T)
371         seaice_obcs: output (SEAICEuseFluxForm=T)
372      and prescribe old default for SEAICEuseFluxForm (=F) and DIFF1 (=0.004)
373          for standard fwd & AD lab_sea tests (to keep the same output).
374    o pkg/seaice/seaice_growth.F:
375      - use Ian Fenty's capping formulas for actual ice
376      thickness thoughout EVOLUTION branch.
377      - put treatment pathological case #2) in CPP brackets
378      (ALLOW_AVOID_INFINITESIMAL_AREA, undef by default).
379      - update global_ocean.cs32x15 and 1D_ocean_ice_colum results accordingly.
380    o pkg/seaice:
381      - seaice_diffusion.F : remove the min(DX,DY) factor permanently;
382      pass the Laplacian diffusivity (in m^2/s) diffKh as a parameter;
383      also pass fac as a param, which can be 1. (to update the tendency
384      field) or the time step (to update the field itself).
385      - seaice_advdiff.F: for multidim, call seaice_diffusion with
386      e.g. SEAICEdiffKhHeff and with fac=1; for single-dim, call
387      seaice_diffusion with e.g. SEAICEdiffKhHeff and with fac=time step.
388      - SEAICE_PARAMS.h, seaice_readparms.F, seaice_check.F :
389      hooks to handle SEAICEdiffKhHeff, SEAICEdiffKhArea, etc.
390    o pkg/seaice:
391      diffusion with centered advection scheme (diffus.F & advect.F):
392      - simplify S/R DIFFUS (put deltaT & DIFF1 factor outside, move EXCH outside)
393        to just compute the laplacian of input-field.
394      - unroll k loop (harmonic,biharmonic diff) in advect.F to save 1 exch call.
395      - fix flux-form version in diffus.F to conserve tracer.
396      update output of lab_sea.fd & lab_sea.hb87 (1rst set of modif affects
397       machine truncation) and lab_sea.salt_plume (conservative flux-form modif)
398    
399    checkpoint62y (2011/05/26)
400    o pkg/seaice:
401     - seaice_growth.F : in EVOLUTION branch, always include
402       a_QSWbyATM_cover in qnet (as it should be).
403     - verification/global_ocean.cs32x15 : update results accordingly
404       (output.seaice.txt output_adm.seaice.txt).
405    o pkg/seaice + obcs:
406     - use maskInW & maskInS in multi-dim advection and biharmonic diffusion:
407       equivalent of assuming no tracer gradient outside the OB region.
408       update output of seaice_obcs (uses DIFF1 <>0 => biharmonic diffusion)
409     - remove calls to OBCS_COPY_TRACER after EXCH calls (no longer needed
410       after changes above);
411     - obcs+seaice cleaning: apply seaice-tracer OB values to tracer field
412       only at OB location (instead of over a band of OLx width).
413    o pkg/seaice:
414     - fix wrong indices in old (non Flux-Form) diffusion default S/R diffus.F
415       (dxG(I+1, ...) changed to dxG(I, ...), no impact on Lat-Lon grid)
416    o pkg/obcs:
417      - split header file "OBCS.h" into 4 separated files:
418        OBCS_PARAMS.h, OBCS_GRID.h, OBCS_FIELDS.h & OBCS_SEAICE.h
419       Note: OBCS_PARAMS.h & OBCS_GRID.h can be included without OBCS_OPTIONS.h
420         (contain no conditional statement which depends on OBCS options).
421      - move "useOBCSYearlyFields" from "data.obcs" (hold in OBCS_PARAMS.h)
422        to parameter file "data.exf", namelist EXF_NML_OBCS (in EXF_PARAM.h).
423    o ctrl, cost, grdchk & autodiff pkgs:
424      - make options file more standard (like other {PKG}_OPTIONS.h file but
425        with AD_CONFIG.h); clean-up some of the included header files.
426    o pkg/obcs:
427      - do not mask tracer when applying OB (tracer == 0 could generate problems)
428      - apply tracer OB values to tracer field only at OB location (instead of
429        over a band of OLx width)
430      - clean-up obcs_apply_w.F & obcs_apply_eta.F (since less calls to these S/R)
431      - remove OBCS_MULTIDIM_OLD_VERSION code in gad_advection.F and remove
432        obcs_apply_tloc.F & obcs_apply_sloc.F
433    o obcs in model/src:
434      - call OBCS_APPLY_W only if NonHydrostatic.
435      - call OBCS_APPLY_ETA only if NonLinFreeSurf.
436      - reset dEtaHdt and wVel to zero outside OB interior region ;
437      - leave tracer unchanged outside OB interior region: This has no effect
438        on the solution but just to prevent unrealistic tracer value outside OB.
439      - zero out velocity outside OB interior region: This has no effect on
440        the solution but just to prevent unrealistic velocity outside OB.
441    o obcs and non-lin free-surf:
442       move call to OBCS_APPLY_R_STAR from update_r_star.F to calc_r_star.F
443       and call to OBCS_APPLY_SURF_DR from update_surf_dr.F to calc_surf_dr.F
444       + add argument "etaFld" to OBCS_APPLY_R_STAR & OBCS_APPLY_SURF_DR:
445       this fixes missing EXCH + get consistent eta OB value (+ fix restart).
446       update results of test-exp. exp4(nlfs).
447    o exp4 (nlfs) test-exp:
448       use OBC for Eta at Western & Eastern OB (to test prescribing Eta
449       with NonLin-FreeSurf); update output.nlfs.txt
450    o obcs and 2d/3d solver norm:
451       use interior masks (maskInC) to cancel out cg2d & cg3d matrix coeff at OB
452       and outside OB interior region (will allow to place OB further inside the
453       domain). Depending on the domain, can affects cg2d-Norm (previous
454       cancellation outside OB was only partial), e.g. in exp4 & obcs_ctrl,
455       and cg3d-Norm (previous Norm was computed before canceling OB terms),
456       e.g. in tutorial_plume_on_slope.
457      - update output of exp.: exp4 (x2), obcs_ctrl and tutorial_plume_on_slope.
458    o pkg rbcs:
459      - split RBCS.h into 3 files: RBCS_SIZE.h, RBCS_PARAMS.h & RBCS_FIELDS.h
460      - add capability to apply relaxation to horizontal velocity uVel & vVel.
461    o pkg/grdchk: add gradient check for control variable xx_shifwflx
462    o pkg/shelfice/shelfice_init_fixed.F
463      fix CPP-flag combinations
464    o pkg/seaice: Merge iceage code of Pierre Rampal
465      * update/change/correct ice age calculations
466      * add age updates for pathological cases
467      Probably needs more testing...
468    
469    checkpoint62x (2011/05/13)
470    o pkg/mom_vecinv:
471       high-order vorticity scheme: use interior masks (maskInW & S)
472       to zero-out (outside OB) gradient of vorticity.
473    o verification exp.:
474       turn on "useEnergyConservingCoriolis" (better discretisation) in exp.
475       hs94.128x64x5 and seaice_obcs ; update results.
476    o pkg/obcs:
477      fix bug in OBeta for YZ sections in obcs_exf_load.F
478    o pkg/ctrl, pkg/shelfice, and optim:
479      - add new control variable xx_shifwflx (fresh water flux underneath ice
480        shelves). This is almost as tedious as obcs-ctrl, because the
481        variables needs its own mask.
482      - add a cost function term that penalizes the deviation of xx_shifwflx
483        from the first guess (zero) in analogy to other control variables
484    o pkg/shelfice:
485      - start basic adjoint
486    o pkg/ctrl:
487      - remove extra 2D field "for good measure" when initializing in
488        ctrl_set_globfld_[xy/xz/yz].F
489      - replace hard coded precision 32 (a bug) in ctrl_map_ini_gen by ctrlprec
490      - improve error messages in ctrl_set_unpack_*
491    o OBC implementation in momentum:
492       use interior masks (maskInC,W & S) in momentum S/R:
493       - multiply divergence, tension and some del^i.u or del^j.v by maskInC
494       - multiply del2u,del2v by maskInW/S (biharmonic viscosity)
495       - multiply horiz. grad of vorticity by maskInW/S (in Leith scheme)
496       - multiply gradient of wVel by maskInW/S in del2w calculation (NonHyd)
497       Motivation: fix/clean implementation of OBC with biharmonic-viscosity
498        (and also with Leith/Smagorinsky harmonic-viscosity).
499       Update output of experiment dome and exp4 (+nlfs).
500    o exp4 test-exp:
501      - turn on: nonHydrostatic, exactConserv, viscA4 (with momDissip_In_AB=F)
502        and prescribe time-varying OB (without pkg/exf) for zonal-velocity
503        at Western & Eastern Boundaries (+/- 1 per-cent); Also prescribe
504        time-varying OB at Western-side for wVel (NonHyd); update output.
505      - add secondary set-up (.nlfs) using NonLin FreeSurf (z*) + mom_vecinv
506        and biharmonic-viscosity ; also use prescribed time varying OB.
507    o pkg/obcs:
508      fix bug in OBWeta,OBWeta indices in obcs_apply_r_star.F
509    o model/src:
510      - fix startTime setting when baseTime<>0 & nIter0=0 are specified ;
511      - initialise startTime & nIter0 with unlikely values: allows to set one
512        from the other without ambiguity.
513    o seaice_obcs test-exp.:
514      add small diffK4T,S to test biharmonic diffusivity with OBCS ; update output.
515    o pkg/obcs:
516      - remove calls to OBCS_COPY_TRACER after EXCH for T,S & pTracer:
517        no longer needed with maskInC,W,S in pkg/generic_advdiff.
518    o pkg/seaice:
519      - retired SEAICE_SALINITY and SEAICE_salinity in favor of
520        SEAICE_VARIABLE_SALINITY and SIsalFRAC, respectively.
521      - fixed bug in the initialization of sea ice salinity variable HSALT
522        in seaice_init_varia.F  (removed dependence on ICE2WATR)
523    o fizhi-cs test exp.:
524       switch reference output convention for these 2 non-standard test-exp,
525        from: pgi  6.1-5 on faulks (FC.6, -of linux_ia32_pgf77+authors_fc5)
526          to: ifort 11.1 on baudelaire (FC.13, -of linux_amd64_ifort11)
527       reason: faulks might get retired soon and pkg/fizhi has still Pb with gfortran
528    o model/inc:
529      - change type of PmEpR array (from _RS to _RL) to fix restart (with "-use_r4")
530        of exp. global_ocean.90x40x15 (Suncronous time-stepping + Real-FW + NonLin-FS)
531    o pkg/seaice:
532      - fix calculation of saltFlux and saltPlumeFlux when using SEAICE_SALINITY
533    o verification/lab_sea, 1D_ocean_ice_column, seaice_obcs, global_ocean.cs32x15
534      - updated output*.txt files due to bug fixes in salt, saltPlumeFlux,
535        and initial HSALT
536    
537    checkpoint62w (2011/04/26)
538    o pkg/mom_fluxform:
539      - fix calculation of del2u & del2v (no-slip BC) when using Non-Lin Free-Surf.
540      - use parameter "sideDragFactor" in no-slip BC side-drag part.
541      - update output of exp. global_ocean.90x40x15
542    o pkg/mom_vecinv:
543      mask del2u & del2v (no effect on results, but cleaner & closer to mom_fluxform)
544    o update seaice exp.:
545      use more consistent parameter values (remove "backward compatability only":
546       ICE2WATR, SEAICE_lhSublim, SEAICE_cpAir, SEAICE_rhoAir + set rhoConstFresh)
547      related to thermodynamics seaice. Update output (fwd+AD) of exp.:
548       1D_ocean_ice_column (x2), lab_sea (x8), ioffline_exf_seaice (x2) & seaice_obcs
549    o update test-exp global_ocean.90x40x15:
550      o use default CD_CODE_OPTIONS file (Adams-Bashforth on CD Mom & Coriolis).
551      o increase Overlap size from 2 to 3 (to allow to test bi-harmonic Visc.)
552      o new pickup-files from a 100.yr run with pkg/down_slope (input.dwnslp params)
553      o turn on zStar & viscA4 in standard set-up (dir input/)
554        and update output files: output.txt & output.dwnslp.txt
555    o new AD-test experiment: obcs_ctrl
556      (From Matt MITgcm_Contrib/SOSE/BoxAdj) to test OBCS as control vector.
557    o pkg/dic:
558      fix two bugs in handling water vapour pressure in carbonate chemistry
559      and air-sea fluxes. Found by Val Bennington and Galen McKinley
560      (add DIC Option = WATERVAP_BUG to recover old results)
561      update output of tutorial_global_oce_biogeo (fwd+AD) & tutorial_dic_adjoffline
562    o adding allowInteriorFreezing option to check for water below freezing point
563      at depth and bring the negative heat anomaly to the surface level
564    o pkgs _fields_load:
565      - extend GET_PERIODIC_INTERVAL to deal with non-periodic case (from pkg/rbcs)
566      - use new S/R GET_PERIODIC_INTERVAL in pkgs:
567        bulk_force, cheapaml, cfc, dic, obcs (+ ctrl/ctrl_get_gen_rec), offline and
568        rbcs to get interpolation weights and time reccord number.
569      - fix multi-threading in aim_fields_load.F
570      - apply EXCH to temp arrays [0,1] after reading in dic_fields_load.F
571    o external_fields_load:
572      new S/R GET_PERIODIC_INTERVAL to calculate which time-record (and linear
573       interpolation weights) to use in a periodic time-series ; do not divide by
574       time-step to convert to integer:
575       - this fixes case where externForcingPeriod is not multiple of time-step
576          (Thanks to Christopher L. Wolfe)
577       - this fixes case where externForcingPeriod is an odd multiple of time-step
578         (was wrong by half of time-step); update results of tutorial_global_oce_in_p.
579      store index of time-record which is currently loaded:
580       - works without any assumption on sequence of calls to EXTERNAL_FIELDS_LOAD ;
581       - needed for the adjoint but not yet used because of extensive recomputations;
582         (to be fixed soon)
583    
584    checkpoint62v (2011/04/02)
585    o verification/1D_ocean_ice_column added to test Ian Fenty's
586      pkg/seaice_growth.F modifications for improving sea ice code differentiability
587    o update output of exp4, internal_wave, seaice_obcs, tutorial_plume_on_slope
588      (new velocity statistics after changing maskInW & maskInS definition)
589    o pkg/generic_advdiff with OBCS:
590      use maksInW & maskInS in advective flux and in biharmonic diffusion calculation:
591      equivalent to assumption of no tracer gradient outside the OB region.
592      This will affect the results if using obcs+biharmonic diffusion.
593      update output_adm.txt of experiment bottom_ctrl_5x5 (not expected since no obc)
594    o pkg/obcs:
595      change definition of maskInW & maskInS: leave OB edges inside (maskIn=1)
596      (e.g., maskInW(OB_Ie)=1 ) so that velocity normal-component at OB is still
597      in Interior region. No impact on solution but affects Velocity monitor stats.
598    o pkg/ptracers (adjoint)
599      New option AUTODIFF_PTRACERS_SPLIT_FILES for writing separate
600      tape file for each tracer
601    o model/inc/src and pkg/autodiff: add parameters that allow to turn
602      of parts of the adjoint code at run time. For now, there are only
603      useKPPinAdMode, useGMrediInAdMode, and useSEAICEinAdMode. These
604      parameters are set in data.pkg.
605      This is the lazy coward's version of doing this, but still useful for
606      debugging. In order to do it right, everything needs to be moved to
607      pkg/autodiff.
608    o pkg/autodiff: fix global_sum_tile_ad.F by resetting adsumPhi at
609      the end; this fixes the adjoint balancing code for open boundaries.
610    o pkg/ctrl:
611      - change behavior of xx_${varname}period to be analogous to exf-conventions:
612        xx_${varname}period =   0.,  means time-independent control part
613        xx_${varname}period = -12., means one-year-periodic monthly control part
614      - introduce helper routine ctrl_init_rec (part of ctrl_init.F) to
615        clean up ctrl_init a little, remove unused variables
616      - ctrl_init: fixed the handling of the start/endrec for obcs-variables
617      - move "call cal_GetMonthsRec" from s/r ctrl_get_gen to s/r ctrl_get_gen_rec
618    
619    checkpoint62u (2011/03/15)
620    o model/src:
621      - for the adjoint, change NonLin-FreeSurf initialisation sequence: fill-in
622        h0Fac from INITIALISE_FIXED and reset hFac to h0Fac in INITIALISE_VARIA ;
623      - in initialise_varia.F (except for ALLOW_DEPTH_CONTROL) remove 2nd call to
624        INI_DEPTHS, INI_MASKS_ETC & INI_LINEAR_PHISURF.
625    o pkg/ctrl/obcs/ecco:
626      - remove obsolete, unused, and partially broken code:
627        ctrl_obcsvol/ctrl_obcsbal/ctrl_volflux and code within
628        ALLOW_CTRL_OBCS_BALANCE
629      - put a stop statement into ecco/cost_obcsvol.F, but also add
630        cost_obcsvol to ecco_ad_diff.list
631    o pkg/ecco: fix counting cost function contributions for obcs (code
632      by Matt M.) and diffkr for diagnostics
633    o pkg/ecco, pkg/ctrl, pkg/grdchk:
634      add cost penalty terms for initial uvel, vvel, eta controls
635      and I/O for prior error files
636    o pkg/mdsio:
637       move mds_check4file.F from eesupp/src to mdsio_check4file.F ; add option
638       (new argument) to check for tiled file in mdsioLocalDir : this fix the
639       restart from pickup_som , pickup_dic (& dic_co2atm) with mdsioLocalDir.
640    o pkg/ctrl:
641     - ctrl_obcsbal.F, ctrl_obcsvol.F: replace last calls of ctrl_getrec by
642       ctrl_get_gen_rec, put a stop statement into ctrl_getrec. Remove
643       unused and superfluous variables
644     - ctrl_get_gen_rec.F: catch the case of xx_genperiod=0.
645    o pkg/ecco
646     - enable adjoint of Stevens OB
647    o pkg/ctrl/ecco/grdchk:
648      - remove global declaration of tmpfldx/yz and tmpfldx/yz2.
649        Fortunately, we do not have any tests for the numerous cpp-flagged
650        option of "obcs as control parameters" so we will never know
651        if this is an improvement (but at least now things compile).
652      - remove an obsolete initialization from ecco_cost_init_barfiles.F
653      - fix some problems within never used ifdefs to make the code compile
654    o pkg/obcs:
655     - Refine Interior mask definition to work with more complex OB (e.g.
656       if OB_Ie < OB_Iw); In case default setting is not sufficient, allows to
657       read in Interior mask from file. Check if Interior mask is consistent
658       with OB list of indices.
659    o pkg/seaice
660     - beginning code for a seaice tracer package,
661       but currently only used for seaice age: SEAICE_AGE
662       SEAICE_num = 4
663       iTracer = 1: area-weighted ice age
664               = 2: volume-weighted ice age
665               = 3, 4: template for one-year vs. multi-year ice
666       data.seaice has new namelist SEAICE_PARM03 for arrays related to
667       SEAICE_num
668    
669    checkpoint62t (2011/03/05)
670    o pkg/obcs:
671     - obcs_apply_uv.F: change to a 2 steps method, first tangential component;
672       then normal component. This ensures that the normal component is set
673       correctly even when it conficts with tangential setting from an other OB.
674       Affects results of test-experiment seaice_obcs: update the output.txt
675    o pkg/obcs:
676     - add code to monitor statistics of dynamical fields at OB.
677     - take OBCS_BALANCE code out of obcs_calc.F into new S/R OBCS_BALANCE_FLOW :
678       - fix to OBCS_BALANCE code (right hFac ; deal with simple OB intersection).
679       - change default: balance the Net inflow through all OB (instead of balancing
680         each OB separately); keep the old method if setting OBC_balanceFacX < 0.
681     - switch on useOBCSbalance in dome experiment: only correct Western OB outflow
682       to match Nortern OB inflow (OBCS_balanceFacN=0).
683    o pkg/seaice:
684     - redefined actual sea ice age to be ICEAGE/HEFF ifdef SEAICE_AGE_VOL
685    o pkg/seaice (seaice_growth v 1.113):
686     - reverting seaice_growth to v 1.111 in order to have code with exact bit
687       compatibility with MITgcm_contrib/ifenty/Fenty_seaice_thermo_code_merge
688       CPP option SEAICE_OCN_MELT_ACT_ON_AREA removed in v 1.112 is reintroduced
689       runtime flag SEAICEareaFormula is kept but is inactive
690    o model/src:
691     - add new param to scale curvilinear grid distance and area when using
692       a different sphere radius from the grid-files.
693     - test/check multi-threads EXCH applied to local variable (cg2d_x)
694    o adjoint:
695     - enable adjoint of Stevens OB
696     - add dummy_in_dynamics to enable extraction of ADJrhoinsitu
697       (a bit delicate because of potentially modified adj. common block structure;
698       current switch is ALLOW_AUTODIFF_MONITOR_DIAG, could be changed later)
699    
700    checkpoint62s (2011/02/15)
701    o pkg/seaice (seaice_growth v 1.112):
702     - introduce SEAICEareaFormula run time parameter, which selects the recipe for
703       computing the ice cover tendency from effective thickness tendencies. Include
704       Ian Fenty's formula.
705     - remove 'undef SEAICE_OCN_MELT_ACT_ON_AREA' which may now be achieved using
706       SEAICEareaFormula.
707     - simplify notations for the various d_HEFF/d_AREA terms.
708    o pkg/gmredi:
709     - add Boundary-Value-Problem bolus transport (Ferrari etal, OM 2010) code
710       from Christopher Wolfe (UCSD); add partial cell factor in vertical derivative;
711       add a verification test-run (front_relax.bvp) to test GM_useBVP.
712    o pkg/seaice (seaice_growth v 1.111):
713     - for SEAICE_DO_OPEN_WATER_GROWTH, replace Gael's implementation with Ian's.
714     - the new SEAICE_DO_OPEN_WATER_MELT allows open-water air-sea heat fluxes to
715       also melt ice.
716    o pkg/seaice:
717     - McPhee formula for Ice-Ocean fluxes (provided by Ian Fenty).
718     - can be used by #define MCPHEE_OCEAN_ICE_HEAT_FLUX in SEAICE_OPTIONS.h
719    o pkg/cheapaml:
720     - from Nico Wienders: New version of this package.
721    o pkg/flt:
722     - add CPP options to prevent floats to re-enter the opposite side of
723       a periodic domain (default: keep periodicity)
724    o pkg/gmredi:
725     - apply exchange to GM_PsiX,GM_PsiY to get valid values near CS-corners
726       (needed for multi-dim advection).
727     - switch on GM Advective form in global_ocean.cs32x15 and update output.txt
728    o model/src:
729     - fix wrong re-setting of addMass array (ALLOW_ADDFLUID) for atmospheric run.
730    o tutorial_tracer_adjsens
731     - extend to NLFS and replace maskC by hFacC
732       (change reference output accordingly)
733    
734    checkpoint62r (2011/01/24)
735    o testreport:
736     - add option -deloutp (-do) to remove output file after successful run
737     - add option -mfile (-mf) for MPI machile-file and for each test-exp,
738       extract exact list of procs from this file ; adjust COMMAND by
739       replacing TR_MFILE & TR_NPROC with local machile-file & Nb of MPI procs.
740    o pkg/ecco: replace old ineffective way of penalizing deviations from
741      first guess (of obcs) with code by Matt Mazloff
742    o pkg/ctrl: add code that allows the use of ALLOW_OBCS?_CONTROL without
743      exf/cal
744      - ctrl_init: fix initialisation (computation of diffrec) for obcs-ctrl
745        and handle case of obcs?period == 0
746        Not affected by these changes: There is still an inconsistency in
747        the computation of start/endrec for the obcs variables for ALLOW_CAL
748        defined (see comment by Menemenlis, 7-Mar-2003)
749      - make S/R ctrl_get_gen_rec return something meaningful even if
750        ALLOW_CAL is not defined
751      - ctrl_getobcs?: simplify code so that it does not need to use
752                       S/R exf_swapfields
753    o testreport:
754       allow to test MPI with different number of processors for each experiment:
755       create file "SIZE.h.mpi" in each build dir.
756       Note: update of "-command" argument not yet implemented.
757    o model/src, pkg/autodiff, pkg/ecco, pkg/seaice:
758      alleviate the need for additional 3D tapes when using
759      the non-inear free surface in the adjoint. This is done
760      by adding an 'update' of hfacc etc. to their current
761      value at the beginning of forward_step.F.
762    o pkg/seaice
763      seaice_lsr: move stress-divergence computations out of outer pseudo-
764      timestepping loop
765    o pkg/obcs/obcs_prescribe_read.F: move 'CALL OBCS_EXTERNAL_FIELDS_LOAD'
766      up, so that the calls of the ctrl_* subroutines are really at the end
767      of the routine.
768    o pkg/gmredi:
769      allow to specify a 2-D horizontal map and a 1-D vertical profil
770      as scaling factor for Isopycnal diffusivity (Redi) and GM diffusivity.
771    o pkg/seaice:
772      move lsr iterations from seaice_dynsolver to seaice_lsr.
773    o pkg/seaice:
774      reduce memory footprint of seaice mutldim advection tapes,
775      by using a 2D tape independent of the generic_advdiff ones,
776      and setting GAD_AREA=1 etc. rather than GAD_AREA=101 etc.
777    
778    checkpoint62q (2010/12/29)
779    o model/src:
780      - check horizontal grid-spacing for unset or zero/negative values.
781      - change AD test hs94.1x64x5 to be truly a 2-D set-up.
782    o pkg/flt:
783      - use (recent) mdsio S/R MDS_READVEC_LOC instead of local FLT_MDSREADVECTOR
784      - precision of input and output files set according to readBinaryPrec
785        and writeBinaryPrec (previously always 64.b), pickup remains at 64 bits.
786      - initial float position from tiled file was not converted to index space
787        (looks like a bug): fixed to make it similar to initial pos. global file.
788    o global_ocean.cs32x15:
789       change SIZE.h of AD set-up to get same tiling as with MPI.
790       Update output_adm, output_adm.thsice (pass@14) & output_adm.seaice (fail@11)
791    o model/src:
792       add flag to control printing of domain fields (bathymetry, hFac ...) in
793       ini_mask_etc (call to plot_fieds_xy*).
794    o pkg/thsice:
795       if useEXF, some forcing fields are not valid in overlap: fixed by computing
796       over the interior only + apply EXCH at the end (like with SEAICE advection).
797    o pkg/mdsio:
798      - add 2 arguments to S/R MDS_PASS_R4/8toRL/S for overlap size of buffer
799        to copy to/from, so that it can be used to replace MDS_PASS_WH_R8toRL/RS.
800      - change barrier call for safe multi-threads access to 3-D shared buffer.
801      - MDS_READ/WRITEVEC_LOC use buffers from MDSIO_BUFF_3D.h (instead of local ones)
802      - replace call to MDS_PASS_WH_R4/8toRL with call to MDS_PASS_R4/8toRL and
803        remove the 4 S/R MDS_PASS_WH_R4/8toRL/S.
804    o pkg/flt:
805      - add fourth-order Runge-Kutta integration
806      - add basic exch2 support (only 1 facet supported so far!)
807    o pkg/mdsio+rw:
808      new S/R to read local (or tile independent) vector (read counterpart of
809       mds_writevec_loc, and front-end write_glvec_rl/rs).
810    o global_ocean.cs32x15: additional input_ad.seaice experiment
811        that uses pkg/seaice rather than pkg/thsice.
812        (using multidim advection for seaice)
813    o towards more F95 syntax for array specification in namelist:
814      - change "data.diagnostics" (data.ptracers was changed before checkpoint62p)
815        of all verification experiments.
816           e.g.:    line: fields(1,3)='ETAN    ','ETANSQ  ',
817          was changed to: fields(1:2,3)='ETAN    ','ETANSQ  ',
818      - finish adding "-DNML_EXTENDED_F77" to DEFINES list in pgf77 and g77 optfiles
819    o global_ocean.cs32x15: additional input.seaice experiment
820        that uses pkg/seaice rather than pkg/thsice.
821    
822    checkpoint62p (2010/12/17)
823    o pkg/thsice: rename (ad tape index) iicekey as ticekey, and move it
824        to THSICE_SIZE.h to avoid conflict with pkg/seaice.
825    o pkg/seaice: add seaice_diffusion.f seaice_map_thsice.f to adjoint.
826        allow for use of multim. advection in seaice adjoint.
827    o pkg/seaice: add diagnostics for snow precipitation and sublimation flux
828      - first attempt to close budgets by taking into account the freshwater
829        flux implied by the sublimation of snow and ice. So far only the
830        volume budget is closed, turn on with soon-to-be-retired-again CPP-Flag
831        SEAICE_ADD_SUBLIMATION_TO_FWBUDGET
832    o eesupp/src:
833      new S/R with new option (NML_EXTENDED_F77) to change array specification
834      from F95 standard to commonly accepted extended F77 form.
835      This would allow to use F95 syntax in namelist (needed with gfortran 4.4.5)
836      and to revert back to the original syntax (with -DNML_EXTENDED_F77)
837      for less tolerant f77 compiler (e.g., pgf77, g77).
838    o globalFiles:
839      commented out in parameter file "data" since it's not safe with MPI
840      (e.g., wrong on aces); keep it if useSingleCpuIO=T (but not doing much
841      in this case); no longer commented out in restart test (tst_2+2).
842    o add adTapeDir to specify a special directory where adjoint tapes are
843      written/read (adread_adwrite.F). adTapeDir is specified in data/PARM05
844      and cannot be used together with mdsioLocalDir.
845    o nesting pkgs:
846      - packages_init_variables : put call to OBCS_INIT_VARIABLES in last position
847      - update Gianmaria's Nesting pkgs (from Contrib/nesting_sannino)
848      - add parameter files + utils dir + output from short run on beagle.
849    o pkg/seaice:
850        fix seaice_growth.F store directives; update results of exp. lab_sea.ad
851    o pkg/seaice: explicitly store tsurfloc in seaice_solve4temp.F to avoid
852      unnecessary copying in adjoint code, requires new parameter NMAX_ITER
853    
854    checkpoint62o (2010/11/25)
855    o pkg/exf:
856      - change CPP option EXF_VERBOSE to run-time logical param exf_verbose.
857    o pkg/seaice:
858      - seaice_ocean_stress: split a loop for better vectorization of the
859        adjoint code
860      - seaice_growth.F: fix bug in conservation of freshwater connected to
861        capping of heff, put contribution into d_HEFFbyNEG
862      - replace irritating parameters SEAICE_latentWater/Ice and SEAICE_sensHeat
863        by something more sensible (parameters that are what their name implies)
864      - change some defaults, so that by default exf-parameters are used for
865        things like rhoAir, cpAir,latent/sensible heat parameters, in order
866        to reproduce the old results, many data.seaice now contain funny values
867        for cpAir and latent heat of sublimation
868    o packages_readparms.F: move exf_readparms up in line so that
869        exf-parameters are visible for other packages (e.g. seaice)
870    o debugMode & debugLevel=2:
871      - differentiate between debugMode & debugLevel=2:
872        debugMode: controls printing of debug messages (sequence of S/R calls).
873        debugLevel: controls printing of algorithm intermediate results and stats.
874      - remove "if debugLevel=2 => debugMode" but keep "debugMode =>  debugLevel=2";
875        => allows to print debug-stats without all sequence of call messages.
876      - switch control of debug print from debugLevel to debugMode in many S/R.
877    o pkg/obcs (obcs-sponge):
878        fix bug that was introduced on Oct 25 (in dynamics.F v1.151): put back the
879        call to OBCS_PRESCRIBE_EXCHANGES (need to exch gU,gV when using obcs-sponge)
880    o pkg/generic_advdiff:
881      - record overlap minimum size for each advection scheme;
882      - refine criteria on overlap minimum size;
883      - check and stop (in gad_check) if overlap size is too small.
884    o pkg/obcs:
885      - with ptracers: remove multiple calls to obcs_apply_ptracer (only done
886        once, in ptracers_implicit.F)
887      - with seaice: remove test on empty file name in obcs_apply_seaice (always
888        apply OB values when tile has OB)
889    o model/src, coriolis setting:
890      - integer parameter "selectCoriMap" (=0,1,2) replaces 3 logical
891        useConstantF, useBetaPlaneF, useSphereF ; can now read coriolis from
892        files (selectCoriMap=3) with any grid.
893      - add parameter "fPrime" for constant second Coriolis coeff (default=0).
894    o pkg/seaice/seaice_growth.F:
895        a few cosmetic changes that reduce the number of lines of code
896    o pkg/obcs: add boundary conditions following Stevens (1990)
897      - the code follows old MOM/NAOSIM code
898      - so far it is only implemented for the eastern and western boundaries
899        and NOT for pTracers
900    o pkg/rbcs:
901      - replace rbcsInIter by rbcsForcingOffset, the time in seconds at the
902        beginning of the first rbcs forcing period.
903      - add option rbcsSingleTimeFiles that makes rbcs read forcing data like the
904        offline package, i.e., one file per time, labeled by iteration number;
905        deltaTrbcs sets the timestep with which the data was generated;
906        rbcsIter0 is the forcing iteration corresponding to rbcsForcingOffset.
907      - rbcsForcingCycle=0 makes forcing non-cyclic.
908      - make arithmetic safe for negative times and odd forcing periods.
909    
910    checkpoint62n (2010/11/09)
911    o pkg/seaice:
912        fix masking in free-drift S/R ; update results of exp. lab_sea.fd
913    o pkg/obcs:
914       New S/R to copy tracer value from the OB location to narrow band region
915        (width = same as overlap) beyond the OB: preserve OB value (needed for
916        high-order scheme) which were overwritten by EXCH call if in overlap
917        region. Applied to theta, salt, ptracer and advected seaice variables.
918       With seaice: use maskInC in similar way as in gad_advection.F,
919        in seaice_advection.F and advect.F.
920       Update output of experiment seaice_obcs and change exp4 to test OBCS with
921        4th order Adv.Scheme. for pasive salt and ptracer.
922    o tools/genmake2:
923      - when looking for an optfile (not specified), only search for Fortran compiler
924        (remove sym-link test + setting of CPP + makedepend check + C-compiler check)
925      - in get_fortran_c_namemangling: use "$CC $CFLAG" to compile C test programm
926        (instead of "$MAKE genmake_test.o" since an existing Makefile can be wrong)
927      - set default for CPP to "cpp -traditional -P" (was the case without specifying
928        an optfile, but otherwise default was just "cpp".
929      - comment out PLATFORM=$p_PLATFORM (no idea where p_PLATFORM comes from)
930      - when "CC" is not set in the optfile, look for possible C compiler
931        (instead of just setting CC=cc)
932      - put back version v.169 modif (from 2008/02/15), was dropped in v.173 changes:
933        => add a ".F" to ".o" rule for source files with no "#include" (such as
934           port_rand.F); otherwise, default ignores FOPTIM and just uses FFLAGS.
935      - move gfortran before g77 in list of possible Fortran compiler (consistent
936        with reference compiler switch from g77 to gfortran)
937    o pkg/seaice:
938      o remove SEAICE_OLD_AND_BAD_DISCRETIZATION-code, add a test to
939        seaice_check that stops the model, when the CPP flag is used.
940      o seaice_growth.F: make capping of ice volume conserving by returning the
941        capped ice as freshwater to EmPmR. This does not change the verification
942        experiments but will change runs where the capping is acutally active
943    o change reference platform+compiler from faulks+g77 to baudelaire+gfortran
944      (except the 2 fizhi test exp.); update output of exp.: bottom_ctrl_5x5,
945         global_ocean.cs32x15 (icedyn, thsice, AD thsice), global_ocean_ebm (AD),
946         lab_sea (fd, hb87, salt_plume), MLAdjust (3/5) and vermix (dd)
947    o tools/genmake2:
948      - merge genmake_warnings & genmake_errors into 1 log file: "genmake.log")
949      - change DUMPSTATE default to false (can use "-ds" option to switch it to T)
950      - clean previous genmake log files before anything else.
951      - change Makefile to remove testreport log files (*.tr_log) and genmake log
952        files only with "CLEAN" target (instead of "Clean");
953    o pkg/generic_advdiff:
954      Change OBCS in multiDim advection (gad_advection.F):
955       Use maskInC to prevent intermediate update of tracer-field in OB regions,
956       thus keeping current-time-step OB values; and remove the call to OBCS_APPLY
957       which were applying future time-step OB values.
958      This way, all explicit calculations use current-time-step OB values
959       (simpler and more consistent).
960      Affects results when set-up uses time-varying OBC and multi-dim advection;
961       update output of experiment seaice_obcs.
962    o pkg/seaice:
963      move OPTIONS (formerly locally defined) to SEAICE_OPTIONS.h:
964       this includes SEAICE_GROWTH_LEGACY (+ SEAICE_DO_OPEN_WATER_GROWTH &
965         SEAICE_OCN_MELT_ACT_ON_AREA ) and SEAICE_SOLVE4TEMP_LEGACY.
966      Default (pkg/seaice/SEAICE_OPTIONS.h) is to define SEAICE_SOLVE4TEMP_LEGACY
967       but leave SEAICE_GROWTH_LEGACY undef ; For now, keep verification exp
968       unchanged (SEAICE_GROWTH_LEGACY defined in */code*/SEAICE_OPTIONS.h)
969    o pkg aim (2010/10/26):
970      - Introduce ALLOW_INSOLATION, moving toward a more general incoming solar radiation
971        formulation with obliquity, eccentricity, ... as run-time parameters,
972      - Introduce diagnostics for top-of-the-atmaophere incoming solar radiation and
973        upward shortwave radition at the surface (all-sky and clear-sky).
974    o pkg/obcs:
975      - writing sections with globalFiles=T does not work: switch to tiled-files
976        when writing sections for OBCS (change pkg/rw/write_rec.F accordingly).
977      - fix index bug (OB_Ie -> OB_Iw_) in obcs_apply_uvice.F
978      - apply OBCS_SEAICE_COMPUTE_UVICE to both uice and vice at all obcs
979    
980    checkpoint62m (2010/10/21)
981    o pkg/seaice: vectorize seaice_solve4temp.F
982      - move iterations loops outside of i/j-loops
983      - requires 2D arrays for TB and effConduct
984      - add 2D iceOrNot to replace HICE_ACTUAL.GT.0, as HICE_ACTUAL is
985        modified in this routine
986      - a little bit of clean up, adjusting indentation, etc.
987      - replaced a few TEN**a by exp(a*log(10.)) in new code for better
988        performance and '**TWO' by '**2' (because TWO is a float),
989        replaced ONE, ZERO
990    o eesupp/src:
991       fix flow dir for exch1_z_RX_cube, exch1_uv_RX_cube & exch1_bg_RX_cube
992    o pkg/seaice/seaice_growth.F
993      Revision 1.89 of seaice_growth.F completes the overall october 2010 revision and
994      merging process. The merged routine has two branches, and one activates the 'evolution'
995      branch by setting SEAICE_GROWTH_LEGACY to undef (at the top of the routine for now).
996      In summary, here is what the '10/10 revision' did consist of
997        part 1: seaice_growth.F revisions 1.71 to 1.75
998          - Preliminary seaice_growth.F clean-up, keeping test results strictly unchanged.
999            The emphasis here was on improving readability (e.g. by trying to use meaningful
1000            variable names) and modularity (e.g. by adding arrays to store heff etc. updates).
1001        part 1.5:
1002          - revising the lab_sea experiment to make it a more useful (i.e. stable
1003            and representative of an actual model run). This was done by generating a
1004            (winter) pickup to start from, switching back the main experiment dynamic
1005            solver from evp to lsr, having one of the experiments use the free drift solution.
1006        part 2: seaice_growth.F revisions 1.76 to 1.85
1007          - Sorting out hard-coded constants that prevented heat and fresh water conservation.
1008          - Sorting out the various fields units and sign (set early on and reset at the end)
1009            to avoid numerous scalings/re-scalings. By v1.85 the basic unit for ice, heat and
1010            fresh water stock is 'effective ice meters', and >0 implies more ice/snow.
1011          - Using tendency terms arrays (d_HEFF* etc.) to alleviate remaining code locks,
1012            and simplifying logical expressions to further improve readibility.
1013        part 3: seaice_growth.F revisions 1.86 to 1.89
1014          - Re-organize the blocks of code more logically.
1015          - Merging the '_if.F' pieces that add something new.
1016    o pkg/thsice:
1017      - vectorize thsice_solve4temp and thsice_get_exf.
1018        Problem: thsice_solve4temp has an unvectorizable statement that
1019        might also be problematic for TAF
1020      - thsice_get_exf: add the ALLOW_BULK_LARGEYEAGER04 CPP-flag. This
1021        does not change the verifcation experiment, but will change all
1022        experiments that have this flag undefined (not tested in verification);
1023        a little reorganization to save a few 2D fields and recomputations
1024      - 1st step of revisiting thsice adjoint (major recomp. sorted out)
1025      - 2nd step:  fix some store dirs
1026        o seems to work somewhat, i.e. using ifort but not g77
1027        o likely cause are incomplete init. or recomputation
1028        o start verification/global_ocean.cs32x15/input_ad.thsice
1029    o pkg/obcs: add support for exch2
1030      - the position of the boundary and prescribed values are specified using
1031        a global domain with exch2 facets stacked
1032        - in x for N,S boundaries (like W2_mapIO=-1)
1033        - in y for E,W boundaries (so E,W boundaries do not overlap)
1034    o pkg/mdsio: add support for writing global sections with exch2
1035        file layout is as for obcs described above:
1036        - for x-z sections, facets are stacked in x (like W2_mapIO=-1)
1037        - for y-z sections, facets are stacked in y
1038    o pkg/thsice:
1039       - change a few routines for better vectorization: thsice_albedo.F,
1040         thsice_step_temp.F, and in thsice_calc_thickn.F. Results are
1041         not affected, but in particular the latter routine has changed
1042         dramatically (not necessarily easier to read now).
1043       - re-arrange calculation in THSICE_SOLVE4TEMP: move outside of i,j loops
1044       iteration loop and call to S/R THSICE_GET_BULKF & THSICE_GET_EXF.
1045    o verification/lab_sea:
1046      - overhaul of the forward model experiments. The main motivation
1047        for this revision is that lab_sea has proven quite fragile (when
1048        changing the sea-ice code, and switching platforms) to a point
1049        when failures were very hard to attribute to specific code problems.
1050      - the suspected reason for this fragility is noise amplification by evp so,
1051        to start with, we decided to replace evp with lsr in the main experiment.
1052      - the input.lsr experiment thus became obsolete and was removed.
1053      - it was replaced with the input.fd experiment that uses an
1054        analytical "free drift" solution as the ice velocity field.
1055      - Taken together, input (lsr), input.fd (free drift) and input.hb87 (evp)
1056        will hopefully allow us to discriminate problems due to dynamic solvers
1057        from problems due to the thermodynamic code. input.salt_plume (lsr) allows
1058        us to test additional options, along with the salt plume package.
1059      - Finally a pickup was generated (at the end of a one year run) to
1060        make the tests more representative of an actual model run. Previously
1061        the tests starting point was a 1m thickness of ice everywhere.
1062    o pkg/seaice:
1063      - introducing S\R seaice_freedrift.F that compute the
1064        analytical solution to an approximate ice momentum
1065        equation (i.e. the simple stress/coriolis balance).
1066      - define SEAICE_ALLOW_FREEDRIFT to trigger the computation
1067        of the free drift velocity field, and enable its use.
1068        To actually use the free drift solution as the model ice
1069        velocity field set SEAICEuseFREEDRIFT to .TRUE. in data.seaice.
1070    o move "useOASIS" from PARAMS.h to EEPARAMS.h and read it from "eedata"
1071    
1072    checkpoint62l (2010/10/04)
1073    o pkg/seaice:
1074      -fix the USE_ORIGINAL_SBI version (for variable freezing point);
1075      -use "celsius2K" in SEAICE_VARIABLE_FREEZING_POINT and in new
1076       version (with USE_ORIGINAL_SBI undef);
1077    o add hooks for new packages OASIS, the package will follow
1078      (hooks exclude the seaice pkg for now)
1079    o pkg/autodiff: ALLOW_AUTODIFF_WHTAPEIO
1080      Option to use mdsio_read_whalos.F/mdsio_write_whalos.F,
1081      rather than mdsio_readvector.F/mdsio_writevector.F, within
1082      adread_adwrite.F to read/write adjoint-related tapes to disk.
1083    o eesupp and pkg/mdsio: ALLOW_WHIO
1084      Option to write/read 2D fields to files including tiles halos.
1085      The main purpose is for adjoint related "tape I/O".
1086      The secondary purpose is for debugging phases.
1087      A word on those rather specifically intended purposes.
1088      The code was meant to be stripped down to the bare minimum.
1089      Typically, there is a unique and basic mapping to the global
1090      buffer (tile by tile, then proc by proc, then level by level), and
1091      byteswaps and meta-files are omitted. Indeed the (*_WH*) code is not
1092      meant to generate user friendly outputs of various shapes and forms.
1093      Rather it is intended, for the knowledgeabale developers,
1094      to be largely independent of the many mdsio options, to allow
1095      outputs of tiles+halos in debugging phases and in adjoint runs,
1096      and to allow some flexibility in tuning (adoint) I/O depending on each
1097      file system behavior. With regard to tuning, most of the potential knobs
1098      (to leave files open, to allocate the I/O indep. of usesinglecpuio,
1099      to specify directories, to specify the typical size of I/O calls, etc.)
1100      are not yet included, and will be added if they prove useful.
1101    o pkg/seaice:
1102       fix uninitialised arrays in USE_ORIGINAL_SBI version of seaice_solve4temp.F
1103    o pkg/seaice:
1104       new S/R seaice_solve4temp.F: this is the merged version of Ian Fenty
1105       code (seaice_budget_ice_if.F) which enable to recover old standard
1106       code (seaice_budget_ice.F) when option USE_ORIGINAL_SBI is defined.
1107       temporary: add "#define USE_ORIGINAL_SBI" at the top of seaice_solve4temp.F.
1108    o model/src (rStar):
1109       use simple average (not area weighted) of rStarFac at U,V point when using
1110       vectorInvariant and selectKEscheme=1,3 (consistent with mom. vertical advection)
1111       update output of exp. fizhi-cs-32x32x40 and fizhi-cs-aqualev20.
1112    
1113    checkpoint62k (2010/09/17)
1114    o adjoint
1115       * changed verification/global_ocean.cs32x15 ; adjoint now tests
1116         Adams-Bashforth 3 + NLFS + RSTAR
1117       * some more modifs required for ECCO-GODAE v4
1118    o pkg/seaice
1119       add SEAICE_AGE_VOL option to use volume instead of area for
1120       integrating SEAICE_AGE
1121    o model/src:
1122       first check-in of sigma & hybrid-sigma coordinate code ; also includes
1123       non-linear free-surface parts ; but pressure-gradient not yet coded.
1124    o pkg/ptracers:
1125       option for ptracer to convert Salt Relax into additional EmP.
1126        tested in exp. global_ocean.90x40x15.dwnslp (update output)
1127    
1128    checkpoint62j (2010/08/25)
1129    o pkg/ggl90:
1130       other minor changes: remove 3-D temp array gTKE (+ add argument myIter)
1131    o pkg/dic: car_flux.F, phos_flux.F
1132      - reduce number of exp-calls in order to improve performance
1133      - clean up a little (replace fields by their macros, etc., fix
1134        typo in CPP-flag)
1135    o pkg/ggl90: minor changes
1136      - GGL90diffKrS was removed --> always use GGL90diffKr
1137      - GGL90viscAr was removed --> replaced with GGL90viscArU, GGL90viscArV
1138      - hack of mxlMaxFlag=2 --> ensure mixing between first and second level
1139        (commented out for now)
1140      - change in max/min operations to ensure that smoothing is ok
1141      - smoothing of GGL90viscAr was moved to ggl90_calc.F (as done for GGL90diffKr)
1142      - always use diffKrNrT as background profile (i.e. never use diffKr field)
1143    o pkg/cfc: bug fix, AREA(i,j,1,bi,bj) -> AREA(i,j,bi,bj)
1144    o pkg/dic:
1145      - model/src/impldiff.F: if TARGET_NEC_SX, extend loop ranges for better
1146        vectorization
1147      - small bug fix in insol for the unlikely case of a cartesian grid
1148      - towards vectorizing the dic package: bio_export.F, car_flux.F, phos_flux.F
1149        + now vectorize, which also removes adjoint recomputations;
1150        + replace integer maksp1 by _RL maskp1
1151        + replace a**x by exp(x*log(a)) in phos_flux.F for speed
1152    
1153    checkpoint62i (2010/07/21)
1154    o pkg/flt:
1155      - with OBCS: stop floats which enter the OB region
1156    o model/src:
1157      - use tempVertAdvScheme & saltVertAdvScheme (instead of horizontal ones)
1158        for implicit vertical advection.
1159    o pkg/seaice:
1160     - account for melting in seaice age evolution.
1161     - remove double counting of seaice ridging effect on seaice age.
1162    
1163    checkpoint62h (2010/06/18)
1164    o pkg/exch2:
1165     - remove exch2_*xy_rx files: call was replaced with exch2_*3d_rx(myNz=1).
1166    o tools/genmake2
1167      - remove "-pdefault" option: redundant with the use of "packages.conf";
1168      - remove file pkg/pkg_default : set the default as a pkg group
1169        ("default_pkg_list") defined in pkg/pkg_groups;
1170      - fix for case pkg/pkg_depend is missing (was hanging before);
1171      - add option "-pgroups" to specify a different pkg_groups than the default.
1172    o verification/adjustment.cs-32x32x1:
1173       add a "minimal" set-up test (code_min & input_min) which only compiles
1174       eesupp/src and the 2 pkgs (exch2 & debug) which don't need model/src & inc.
1175    o tools/genmake2
1176      - extend pkg_depend rules to model & eesupp (e.g., if model depend on [pkg]))
1177      - fix details of checking for mnc & profile pkg when NetCDF is unavailable.
1178    o pkg/exf: merge exf_bulk_largeyeager04 into exf_bulkformulae because these
1179      files are nearly the same anyway.
1180      Step 1: make exf_bulkformulae look like exf_bulk_largeyeager04:
1181       - redefinition of tau(i,i) (by a factor of ustar)
1182       - 1./exf(Const/T) -> exf(-Const/T) (big change in the results)
1183       - replace rhonil by rhoConstFresh in computation of evap (bug fix)
1184       - replace u/vstress=tau*rd*ws*cw by tau*rd*u/vwind (changes results)
1185       - replace
1186         rd(i,j)= rdn(i,j)/(exf_one - rdn(i,j)/karman*psimh )
1187         shn    = sh(i,j,bi,bj)*rd(i,j)/rdn(i,j)
1188         by
1189         shn    = sh(i,j,bi,bj)/(exf_one - rdn(i,j)/karman*psimh )
1190         (changes results)
1191       -> exf_bulkformulae v1.22,
1192          update verification experiments lab_sea, offline_exf_seaice, seaice_obcs
1193          (lab_sea: output.hb87.txt 1.11, output.lsr.txt 1.25, output.salt_plume.txt 1.13,
1194                    output.txt 1.63
1195           offline_exf_seaice: output.seaicetd.txt 1.7
1196           seaice_obcs: output.txt 1.10)
1197      Step 2: do the actual merge and remove exf_bulk_largeyeager04.F
1198       -> exf_bulkformulae v1.23,
1199          unfortunately requires updating lab_sea.salt_plume (6 matching digits),
1200          and global_ocean.cs32x15.icedyn (only 11 matching digits)
1201      Also update output_adm of exp. lab_sea (all 4) and offline_exf_seaice.
1202    o adjoint of exch-1:
1203     - pass high-level EXCH S/R through TAF (eesupp/src/exch_ad_diff.list)
1204       (note: was already like this when using EXCH-2) and remove flow dir
1205       and hand-written AD version of high-level EXCH S/R (pkg/autodiff);
1206     - provide flow-dir for low-level exch1 S/R (eesupp/src/exch1_ad.flow);
1207     - update pkg/exch2 diff list.
1208    
1209    checkpoint62g (2010/05/19)
1210    o eesupp/src (exch-1):
1211     - split exch_rx.F into Forward S/R (exch1_rx.F) and Adjoint S/R (exch1_rx_ad.F)
1212       and remove argument "simulationMode"; same thing for all exch_*rx_cube.F
1213       (renamed to exch1_*rx_cube.F).
1214     - change accordingly exch_*_rx.template and AD version in pkg/autodiff
1215       to call new exch1 S/R ; update Makefile and .cvsignore.
1216     - replace call to exch2_xy_rx S/R with exch2_*3d_rx(myNz=1) (will remove
1217       exch2_xy_rx later)
1218      Note: after updating your code, need to run "make clean" in eesupp/src
1219    o test experiment bottom_ctrl_5x5:
1220       new output_adm.txt with fewer grdchk & less monitor output.
1221    o model/src:
1222      remove the call to ini_cori in initialise_varia.F (just keep the usual one
1223       in initialise_fixed.F). More consistent with coriolis & horizontal grid
1224       beeing treated in the same way (ini_grid is not called a 2nd time).
1225    o pkg/exf:
1226      - rewrite exf_bulk_largeyeager04.F for better vectorization, changes
1227      global_ocean.cs32x15/input.icedyn (11 digits of agreement), updated
1228      - fix adjoint (used worked for ALLOW_ATM_WIND defined, works for this now)
1229      - cosmetic changes to exf_bulkformulae.F to make it look more like
1230        exf_bulk_largeyeager04.F
1231    o eesupp/src (exch-1):
1232      - Fix AD EXCH code for 2-D domain special cases (Nx=1 or Ny=1).
1233      - Separate buffer filling and MPI sending: allow EXCH-1 to work for local
1234        array (non-shared) when using MPI+MTH. Also reduces number of BARRIER
1235        (even without using MPI).
1236      - Message mode: move RecvAck setting (indicator of buffer being ready)
1237        from send_put to recv_get S/R (was useless before, but not sure if
1238        it's much more useful now);
1239      - Switch the order of sync: MPI-proc 1rst and then threads;
1240      - take out spin-waiting code (#undef EXCH_USE_SPINNING), use BARRIER instead.
1241      - fix AD code for communication mode ='get' (but not used).
1242    o model/src:
1243      initialise dPhiHydX,dPhiHydY inside calc_grad_phi_hyd.F (so that TAF does
1244      not drop it in S/R mddynamics, producing NaN in hs94.1x64x5 AD-test exp).
1245    o utils/matlab/rdmnc.m: adapt to be able to use the generic matlab netcdf API
1246    o pkg/ctrl: require a specific set of control variables and exf-flags for
1247      adjoint of seaice (stop in ctrl_check.F if conditions are not satisfied)
1248    o model/src:
1249     a) 1rst version of a new driver S/R to turn-off output freq and flags after the
1250       1rst forward sweep, to avoid over-writing output files during recomputations
1251       recomputations (& grdchk); called from cost_final.F (& ctrl_init_ctrlvar.F ?)
1252     b) 2nd version:
1253      - add specific pkg S/R for seaice & ptracers (called from S/R TURNOFF_MODEL_IO);
1254      - switch-off more output flags (exf_monFreq, chkPtFreq, dumpInitAndLast,
1255         writePickupAtEnd) + seaice & ptracers output;
1256      - do not switch off MNC flags (otherwise, won't get admonitor netcdf file)
1257    o model/src:
1258      - new S/R rotate_uv2en_rl (..._rs) that rotates vector fields.
1259    o pkg/exch2:
1260      - remove "simulationMode" from arg. list of S/R EXCH2_RX1,2_CUBE ;
1261      - add argument "signOption" to EXCH2_RX1_CUBE (will be needed for SM exch).
1262    o pkg/autodiff & exch2:
1263      process exch_uv_agrid_3d_rx.f & exch2_uv_agrid_3d_rx.f through TAF
1264      (for now, only if ALLOW_EXCH2 is defined).
1265    o pkg/autodiff:
1266      - include PACKAGES_CONFIG.h in exch*ad.flow & exch*ad.F
1267        (not supposed to be in CPP_OPTIONS.h) to get ALLOW_EXCH2 defined correctly.
1268       + clean-up comments (_RS is not always real*4)
1269      - fix bug in ADEXCH_UV_3D_RX (without EXCH2, was calling the forward exch S/R)
1270      - add a stop in ADEXCH_UV_AGRID_3D_RX if trying to use it with EXCH2:
1271        was calling a forward exch2, which is wrong ; used in SEAICE & EXF pkgs.
1272    o testreport (AD-tests):
1273      no longer link files from dir "../input" (1rst link files from
1274      "../input_ad.[xx]" if secondary test "xx" and then from "../input_ad")
1275    
1276    checkpoint62f (2010/04/29)
1277    o model/src/the_main_loop.F:
1278      adjust store directives for seaice evp and multicategory according to
1279      pkg/ecco/the_main_loop.F
1280    o adjoint:
1281      global_sum_ad was incomplete (noted many times by many people ;)
1282      nice description by Jean U. as follows:
1283      * allreduce(var) in global_sum.F can be interpreted as
1284        reduce(sum) followed by broadcast of sum.
1285      * The adjoint of that is
1286        sum(adjoint) followed by broadcast(summed adjoint value)
1287        or in other words, allreduce(sum, adjoint vars)
1288      We were missing the sum(adjoint)!
1289      Benign, except(!) for "global" scalars appearing in tile loops (bi,bj)
1290      (noted by J.M. Campin, e.g., in cost_ssh_mean, variable offset).
1291      The fix should produce 16-digit accuracy between
1292      single-CPU multi-tile (e.g. nSx=2, nPx=1) and
1293      multi-CPU single-tile (e.g. nSx=1, nPx-2)
1294      We'll probably change this yet again shortly
1295    o eesupp/src:
1296      - fix global_sum_r4 (wrong from previous modif in Jun 2009; ever used ?)
1297    o pkg/icefront
1298      - ALLOW_SUBGLACIAL_RUNOFF option adds capability for time-evolving
1299        specification of addmass array based on a 2D field, which is added
1300        at bottommost wet level at each horizontal location.
1301    o model/src:
1302     horizontal grid initialisation (other than curvilinear): add code for Exch2 IO
1303     layout; (not always compatible with delX,delY setting; commented out for now).
1304    o pkg/exch2:
1305     change tile to processor setting (case nSy*nPy > 1): allows default model mapping
1306     (myX and myYGlobalLow) to be used for simple (1 facet, no blank tile) config.
1307    
1308    checkpoint62e (2010/04/15)
1309    o pkg/obcs:
1310      - fix wrong index in OBCS_SPONGE_V for Eastern-OB (reported by David Hebert).
1311    o pkg/dic:
1312      -fix bug in fe_chem.F for multi-tile (nSx*nSy > 1) set-up;
1313        (note: not presently tested in any forward verification exp.)
1314       update tutorial_global_oce_biogeo AD output file.
1315    o pkg/exf:
1316      - account for the variation of albedo as a function of zenith angle
1317        by defining ALLOW_ZENITHANGLE in EXF_OPTIONS.h
1318    o build_options:
1319     - rename "linux_ia64_ifort+mpi_ice_nas" to "linux_amd64_ifort+mpi_ice_nas"
1320    o pkg/dic:
1321      change DIC atmos-CO2 box (method 3, dic_int1=3) initialisation & restart:
1322      - use binary pickup file for restart;
1323      - initialise atmos-CO2 box from dic_pCO2 parameter;
1324      - fix multi-threaded.
1325    o pkg/rbcs:
1326     - clean-up RBCS code: add RBCS_OPTIONS.h file ; fix multi-threaded ;
1327       change (+ fix IO calls) type of array RBC_mask from _RL to _RS.
1328     - add RBCS to exp4 passive tracer 01 (rbcs was previously untested)
1329       and update output.txt
1330    o pkg/kpp:
1331     - add diagnostics for KPP non-local flux of Temp, Salinity and pTracers;
1332     - change diagnostic of KPP non-local term: output average of KPPghat*KPPdiffKzS
1333       (= ratio of KPP non-local (salt) flux relative to surface-flux) when
1334       using pkg/timeave & pkg/diagnostics (diag 'KPPghatK' replaces 'KPPghat ');
1335     - change pkg/offline to read-in average KPPghat*KPPdiffKzS from file
1336       KPP_ghatKFile (instead of the average of KPPghat from file KPP_ghatFile).
1337    o pkg/offline:
1338      fix bug in S/R OFFLINE_FIELDS_LOAD regarding surfaceForcing conversion factor
1339      (bug was added in version 1.10 on 2007-08-23).
1340    o pkg/offline:
1341      - no need to specify periodicExternalForcing, etc ... to use offline pack
1342      - offline input files no longer just single prec --> parameter offlineLoadPrec
1343    o verification/lab_sea:
1344      change AD test to multi-tile setup and update all 4 AD output.
1345      NOTE: while cost function values remain very similar,
1346      gradients are very different, although gradient checks are self-consistent
1347      Should try to get to the bottom of this (cost function summation order?)
1348    o pkg/dic:
1349      in carbon_chem.F, replace log10 (AUTODIFF) with explicit form to avoid
1350      a weakness of TAF that drops part of double precision in log10 derivative.
1351      <= changes removed since problem has been fixed in current TAF version 1.9.71
1352      update AD output of exp. tutorial_dic_adjoffline & tutorial_global_oce_biogeo.
1353    o pkg/ecco:
1354      add missing "_d 0" in cost_readers.F, cost_readtopex.F & cost_readtopexmean.F
1355      update all 4 lab_sea AD output.
1356    
1357    checkpoint62d (2010/03/22)
1358    o build_options:
1359      remove '-r8' (and '-i4') from linux_*pgf and linux_*ifort optfiles.
1360    o remove unbalanced quote (single or double) in commented line of source code
1361      (may cause some warning with some preprocessor/makedepend versions).
1362    o pkg/seaice:
1363      fix seaice_model.F for adjoint (gael) and update AD results of experiments
1364       lab_sea (std + evp + noseaicedyn) and offline_exf_seaice.
1365    o testreport:
1366      add option '-runonly' (short: '-ro') to just do the run part (without make).
1367    o eesupp: remove JAM communication code (obsolete).
1368    o add option to genmake2 & testreport to switch "_RS" type to "real*4"
1369      (if allowed in CPP_EEOPTIONS.h); update default CPP_EEOPTIONS.h and return
1370      to default CPP_EEOPTIONS.h for exp. inverted_barometer & solid-body.cs-32x32x1
1371      (update also the output).
1372    
1373    checkpoint62c (2010/03/02)
1374    o tools/build_options :
1375       move (some) old optfiles from build_options/ to build_options/unsupported/
1376    o model/src and pkg/exf
1377       surface relaxation -- separating data and data.exf options
1378       The point is to ensure that we specify the surface relaxation
1379       either in data or in data.exf (but not half and half) and to
1380       avoid an accidental relaxation to 0 (which happened if a time
1381       scale was specified but the file name was left empty)
1382    o model/src model/inc and pkg/mom_common
1383       ALLOW_3D_VISCAH/ALLOW_3D_VISCA4 => 3D specification of Viscosity
1384       => addition to the viscosity field as computed by others schemes
1385    o tools/build_options:
1386      - rename "_generic_mpi" -> "+mpi_generic" (like other "+mpi" optfile)
1387        but keep the former optfile for few weeks for smooth transition
1388    o pkg/ecco
1389      - allow user defined cost function contributions
1390         CPP: ALLOW_USERCOST_CONTRIBUTION
1391         USAGE: compute contributions in cost_usercost_all.F
1392      - note: this is identical to what ALLOW_GENCOST_CONTRIBUTION once was.
1393          the two options are complementary.
1394    o pkg/smooth
1395      - migration from contrib to the main repository
1396    
1397    checkpoint62b (2010/01/26)
1398    o pkg/monitor:
1399      - change back mon_printstats_rl.F & mon_stats_rl.F and add a stop
1400        (in case someone forgot to update customized pieces of code)
1401    o nonHydrostatic:
1402      - add Non-hydrostatic free-surface form (selectNHfreeSurf=1)(not fully tested);
1403      - add a simple 2-D experiment (short_surf_wave) to test it.
1404    o pkg/icefront:
1405       adding the shell of, and the hooks to, a new package that
1406       will model melting and freezing of vertical glacier ice fronts
1407    o momentum:
1408      add diagnostics of momentum tendency from Hydrostatic pressure gradient
1409       (without surf.pressure term: would need a 2nd filling since implicit term).
1410    o add 3 "_d 0"s so that fizhi compiles with xlf on iblade, and replace
1411      two " &end" by " &" (in fizhi-cs-*) because S/R NML_SET_TERMINATOR
1412      cannot deal with the former
1413    o cleaning:
1414      - remove all (except OpenAD) old TLM output from results_ad dirs.
1415      - remove unused S/R (MDSWRITEMETA, DIAGNOSTICS_ADD2LIST, old DFILE IO S/R)
1416      - comment out maskH definition (replaced by maskInC)
1417    o pkg/monitor:
1418      - change mon_printstats_rl.F & mon_stats_rl.F (were similar to mon_writestats_rl
1419        & mon_calc_stats_rl) to be the RL equivalent of mon_printstats_rs & mon_stats_rs.
1420    
1421    checkpoint62a (2010/01/15)
1422    o model/src:
1423      - bottom pressure diagnostic: correct for r* (when nonlinFreeSurf >= 4)
1424    o pkg/diagnostics:
1425      - add optional level number diagnostics (i.e., level number to be define
1426        explictly with S/R DIAGNOSTICS_SETKLEV) with parser-code(10)="X".
1427      - strictly check for valid parser-code(10) ;
1428      - check if adding diag to the list from the right place.
1429    o pkg/longstep:
1430      - change parameters and fix tracer conservation with rstar/nonlinear free surface
1431    o diagnostics:
1432     - in all pkgs, replace remaining calls to old S/R DIAGNOSTICS_ADD2LIST with newer
1433       S/R DIAGNOSTICS_ADDTOLIST ; fix seaice VICE diagnostics.
1434  o pkg/diagnostics:  o pkg/diagnostics:
1435   - Add option for writing vertical integral (sum of selected levels) of an output   - Add option for writing vertical integral (sum of selected levels) of an output
1436      field instead of writing output field levels. Activate this option on a per      field instead of writing output field levels. Activate this option on a per
