5      ==============================      ==============================
6    
7    o pkg/autodiff:
8      - rename S/R INI_AUTODIFF to AUTODIFF_INIT_VARIA ;
9      - create new header file "AUTODIFF_PARAMS.h" for pkg/autodiff parameters
10        which are now read from new parameter file "data.autodiff" (inAdExact
11        previously in "data", use{KPP/GMRedi/SEAICE}inAdMode previously in data.pkg)
12      - add file "data.autodiff" in all verification/*/input_ad/ directories.
13    o verification/tutorial_tracer_adjsens/
14      - add extra sub-verification which uses "SOM" advection scheme
15        (2nd Order-Moment Advection Scheme, Prather Limiter) with
16          #define GAD_ALLOW_TS_SOM_ADV in GAD_OPTIONS.h
17        and in data:
18          multiDimAdvection=.TRUE.,
19          tempAdvScheme=81,
20          saltAdvScheme=81,
21    
22    checkpoint63o (2012/06/29)
23    o vertical mixing schemes:
24      - remove unused S/R CALC_BUOYANCY (left from branch-atmos merging)
25      - replace computation of density (in Function STATE1, opps_calc.F) by a call
26        to S/R FIND_RHO_SCALAR
27      - pass sigmaR to S/R PP81_CALC, MY82_CALC (but not yet used) and to GGL90_CALC
28        and use it for N^2 calculation in ggl90_calc.F (save 2 density computations);
29        affects output (vermix.ggl90) at truncation level.
30    o testreport:
31      - change adjustment of SIZE.h for mpi+mth testing: preserve enough tiles
32        (nSx,nSy) for the number of threads (from eedata.mth)
33    o model/src:
34      - remove 2nd set of calls at the top of initialise_varia.F (Adjoint part)
35        related to Non_Lin Free-Surf or Bottom-Control (but not longer necessary).
36    o verification/tutorial_tracer_adjsens/
37      - compile with ALLOW_CG2D_NSA
38      - run with nonlinFreeSurf=3
39      - update reference output_adm.txt
40    o tools/genmake2:
41      - add "-DHAVE_NETCDF" to the DEFINES list when NetCDF is available ;
42        refine usePROFILES switching off (only when NetCDF is not available).
43    o verification (atmospheric set-up):
44      - change eosType='IDEALGAS' to eosType='IDEALG' to match variable declaration
45    o pkg/profiles : refine profiles and files handling.
46    o model/src and pkg/ecco : introduce run-time switch usePROFILES.
47    o model/src/the_main_loop.F, forward_step.F and pkg/exf/EXF_OPTIONS.h :
48      - changes to use model/src/the_main_loop.F rather than the ecco version
49        in ecco type adjoint runs.
50    o model/src:
51      - move computation of recip of grid distance & area from INI_MASKS_ETC to INI_GRID
52      - move setting of h0Fac[C,W,S] from INI_LINEAR_PHISURF to INI_MASKS_ETC
53      - update_masks_etc.F: rename SMOOTH*_R4,R8 function to the corresponding type (RS,RL)
54    o model/src:
55      - fix S/R UPDATE_CG2D for ALLOW_DEPTH_CONTROL case (was empty before);
56        update output of test experiment bottom_ctrl_5x5.
57    o pkg/generic_advdiff:
58      - implement vertical bi-harmonic diffusion (for now, only for T & S and
59        only explicitly).
60    o verification/bottom_ctrl_5x5/
61      update reference output (results changed quite some time ago,
62      not sure when; but new reference results look ok in terms of grdchk)
63    o verification/1D_ocean_ice_column/
64      For verification purposes, the exact adjoint rather than an approx.
65      should be used (e.g., to comare against F.D. or TLM).
66      removed autodiff_inadmode*_ad.F routines in code_ad/
67      Update results/ accordingly.
68    o pkg/cal:
69      - change cal_getdate.F so that output date is function of input time only
70        (less ambiguous, not mixed up with input iteration number).
71      - fix calendarDumps for non-zero phase-lag (S/R CAL_TIME2DUMP).
72    o pkg/diagnostics:
73      - implement calendarDumps also for stats-diags
74      - implement calendarDumps also for snap-shot output (negative freq)
75      - for now, ignores calendarDumps if non-zero phase-lag.
76    
77    checkpoint63n (2012/06/04)
78    o model/src:
79      - recompute rSurfW & S to ensure consistent column thickness (needed for rStar)
80        between Sum_k(hFac*drF) and rSurf-rLow, for now only when using pkg/shelfice;
81      - use h0FacC, W & S to compute hFac_surfC, W & S in calc_surf_dr.F (more
82        similar to calc_r_star.F); update results of experiment internal_wave and
83        tutorial_global_oce_in_p (affected @ truncation level).
84    o pkg/shelfice:
85      - add parameterisation of advective-diffusive flux into the ice shelf
86        according to Holland and Jenkins (1999), eq.22-33, as suggested by Jan De Ryd
87      - simply eps3/3a computation
88    o eesupp:
89     - add new CPP option (DISCONNECTED_TILES) to disconnect tiles (no exchange
90       between tiles, just fill-in edges assuming locally periodic subdomain) and
91       add corresponding exchange subroutines (EXCH0);
92     - new CG-solver version (_EX0) for disconnected-tiles special case.
93    o model/src (CG-solvers):
94     - modify Single-Reduction version (CG2D_SR) in case cg2dMaxIters is reached
95       (similar final residual output and max-Iter number as with standard version);
96     - allows to store and use lowest-residual solution (standard & _SR versions);
97     - cleaning up (remove old, commented out code, LETS_MAKE_JAM ...).
98     - by default, also compile CG2D_SR version (define ALLOW_SRCG in CPP_OPTIONS.h)
99    o eesup/src:
100     - global_vec_sum.F cleaning: add a BARRIER ; update comments ; remove ndef
101       ALWAYS_USE_MPI (no longer needed after fixing usingMPI settings - March 2012)
102    o pkg/salt_plume added to lab_sea/input_ad.noseaicedyn
103    
104    checkpoint63m (2012/04/27)
105    o pkg/shelfice:
106     - account for partical cells in surface level below ice-shelf for hydrostatic
107       pressure calculion (set uniformFreeSurfLev to F); update isomip experiments.
108    o ad test experiments:
109     - update and rename to "ad_optfile.local" local AD-optfile specific to a
110       particular adjoint verification experiment (in verification/*/code_ad/)
111    o pkg/seaice & pkg/exf:
112     - Part two of ECCO-CLIVAR code merges.
113       Completes merge of seaice area relax. code.
114       Requires unified CPP option EXF_ALLOW_SEAICE_RELAX
115       to be set in EXF_OPTIONS.h since this pkg controls its I/O
116       (and avoids second CPP option in SEAICE_OPTIONS.h)
117     - change default value of costIceStart & costIceEnd to a valid date.
118     - add snowPrecip to HSNOW in seaice_growth
119    o pkg/ptracers:
120     - move ptracers summary and setup check into separated S/R ; add a check for
121       valid PTRACERS_Iter0 value (error+stop or just warning).
122    o pkg/cal (+ pkg/ecco):
123     - avoid calling a S/R with 2 times the same arg (FWD: unless both are only used
124       as input; and for AD, unless both are not differentiable (e.g., k index)).
125    o model/src:
126     - define internal flag "uniformFreeSurfLev" (=T when free-surface level-index
127       is everywhere k=1) to speed-up some calculations (by pass kSurf reference);
128       temporary set to usingZCoords value (to be changed to F when using shelfice).
129     - hydrostatic pressure: implement partial cell near the surface also for
130       Z-coordinates (for the case where uniformFreeSurfLev=F); replace test on
131       usingZCoords with test on uniformFreeSurfLev where needed (in NonHyd code).
132    o pkg/ctrl/ctrl_init.F:
133     - add a formal parameter to s/r ctrl_init_rec to print
134       xx_$(ctrl_valiable)_file for easier debugging
135     - move call of cal_* routines into the if-block where they are really
136       needed so that xx_$(ctrl_variable)_period can be 0 or -12 without having
137       to specify a startdate
138    o pkg/seaice:
139     - update comments in SEAICE_OPTIONS.h (+ similar update of lab_sea/code and
140       global_ocean.cs32x15/code versions).
141     - turn on seaice Multi-category (in data.seaice, SEAICE_multDim=7) for
142       verification experiment global_ocean.cs32x15.seaice and update results.
143    o pkg/exf:
144     - new S/R EXF_GETFIELD_START to return starting-time of a forcing field
145       (according to useExfYearlyFields).
146    o pkg/cal:
147     - move calendar setting & summary (previously in cal_readparams.F) into new
148       S/R CAL_INIT_FIXED to be called later in the initialisation process, once
149       length of the simulation is set (after SET_PARMS call); This is an attempt
150       to fix Pb when, e.g.: pkg/longstep, modifies the length of the run.
151     - For safety: keep a record of pkg/cal parameter settings status
152               to allow to STOP if one pkg/cal S/R is called too early.
153     - add a stop in all basic pkg/cal subroutines if called before setting is done.
154     - modify cal_getdate.F: stop when nothing was returned;
155       if called with myIter=-1, simply retrun modelBaseDate (1,2 = startDate_1,_2);
156       this allows to remove "cal.h" from seaice_read_parms.F & init_mnc_vars.F.
157    
158    checkpoint63l (2012/04/04)
159    o pkg/bbl:
160      - fix call to FIND_RHO_2D in bbl_calc_rho.F (case multi-tiles per proc);
161        update global_with_exf output.yearly.txt file.
162    o pkg/cal:
163      - start to clean-up cal_set.F ; fix for the case where baseTime is non-zero.
164      - remove 2 unsused and very short (1 line only) functions ;
165      - remove unsused subroutines from AD-Diff list.
166    o model/src:
167      - start to implement clean wait to stop in initialization S/R (config_check.F,
168         packages_check.F, ini_parms.F and pkg/obcs/obcs_check.F + pkg/mypackage)
169    o folowing PRINT_MESSAGE changes:
170      - remove reminder multiple print to the same file (STDOUT) when multi-threads.
171    o pkg/bbl:
172      - modification so it can work with z*
173      - replace deltaT with dTtracerLev(k) for asynchronous time stepping
174      - global_with_exf/input.yearly verification; changes output.yearly.txt
175    o eesupp/src:
176      - PRINT_MESSAGE: use OpenMP critical instruction (similar to PRINT_ERROR);
177        writing to unit 0 (if unit=errorMessageUnit) extended to the case myThid=1
178      - CHECK_THREADS: specific code if using OpenMP threading: improve checking of
179        # of threads across processors (e.g., different env OMP_NUM_THREADS setting)
180      - improve special preliminary call to EESET_PARMS (if eedata is read 2 times).
181      - when using MPI, always set usingMPI=T ; set default accordingly and stop
182        if not consistent.
183      - ALL_PROC_DIE: add a BARRIER after MPI_FINALIZE call ; skip this when thread
184        argument is zero (in case called within single-thread section).
185    o pkg/fizhi:
186        clean-up turbulence cold-start switch: decided in fizhi_init_vars.F, stored
187        in common bloc (fizhi_coms.h) and then passed as argument up to S/R TURBIO.
188    o pkg/exch2:
189      - add argument "updateCorners" to S/R exch2_get_uv_bounds (enable to
190        activate EXCH_IGNORE_CORNERS in vector EXCH S/R).
191      - switch 1rst EXCH call to IGNORE_CORNERS (instead of UPDATE_CORNERS)
192        but keep the 2nd with UPDATE_CORNERS: this prevents overwriting good data
193        with bad ones coming from a not-yet-updated halo.
194        This should fix the problem when sNx <> sNy and GCD(sNx,sNy) < 2*Olx.
195    o pkg/frazil:
196        move FrzForcT diag from frazil_diagnostics_state.F to frazil_calc_rhs.F
197        http://mitgcm.org/pipermail/mitgcm-devel/2012-March/005384.html
198    o model/src/config_check.F: add a check for OLx>sNx/OLy>sNy
199    o verification/lab_sea
200      * #undef SEAICE_EXCLUDE_FOR_EXACT_AD_TESTING
201      * #define ALLOW_SST_CONTROL & ALLOW_SST_CONTROL
202      * nTimeSteps 3 -> 4
203      * changed reference output accordingly
204    o pkg/ctrl:
205      * fix ctrl_get_gen for xx_sst, xx_sss
206    o pkg/fizhi:
207      - fix 2 calls to S/R GRD2MSC (argument igrd) in update_earth_exports.F
208        update results of exp. fizhi-cs-32x32x40 (fail with only 6 digits for cg2d)
209      - by default, use new version of S/R GETPWHERE (#define TRY_NEW_GETPWHERE);
210        fix few out-of-bounds indices in referencing vars (initialise igrd to 1);
211        clean-up fizhi_turb.F (remove unused & uninitialised qdiaglsm array).
212    o pkg/gmredi:
213      - add diagnostic of Redi (main diagnonal) vertical diffusive flux of Temp
214    o pkg/fizhi:
215      - fix few initialisation and multi-tile Pb: aqualev & gridalt now pass the
216        (old)aces open64 tuv test.
217    o pkg/icefront: fix bug and reorder loop in icefront_init_varia.F
218    o pkg/mom_vecinv:
219      - fix 1 loop range in mom_vecinv.F to be like all the other loops which
220        set/update gu,gv/Diss (fix Pb of uninitialised fVerUkp in admom_vecinv
221        with non-lin free-surf).
222    o model/src: move k-loop outside of i/j-loops when (re-)computing R_low
223      in ini/update_masks_etc.F in order to avoid -O3 optimization problems with
224      some compilers (gfortran 4.6.0 on MacOS)
225    o momentum:
226      - separate fVer?(:,:,kUp) & fVer?(:,:,kDown) in argument list of MOM_FLUXFORM
227        & MOM_VECINV subroutines (to help TAF). This fixes Pb of uninitialised
228        fVer?(kUp) in admom_fluxform with non-lin free-surf or bottom control.
229    
230    checkpoint63k (2012/03/17)
231    o model/src:
232       - selectAddFluid (ALLOW_ADDFLUID): add missing term in horizontal momentum
233         flux-form (mom_fluxform.F) and vertical momentum (calc_gw.F) equations.
234       - SOLVE_DIAGONAL: switch default to use adjoinable & vectorized version
235         (#undef SOLVE_DIAGONAL_LOWMEMORY); update output of exp. front_relax.bvp.
236    o model/src: solve_*diagonal.F
237       - replace division with multiplication by inverse (similar to original version)
238         update output of AD exp. global_ocean.90x40x15.
239       - fix pkg/gmredi/gmredi_calc_psi_bvp.F & pkg/ggl90/ggl90_calc.F
240         to enable the use of the vectorized & differentiable solve_tridiagonal.F
241       - test exp. global_ocean.90x40x15/input_ad: switch to advection scheme 20 for
242         vertical advection (to get solve_tridiagonal tested in AD mode).
243    o pkg/seaice: ECCO-CLIVAR merge:
244      1. seaice AREA relaxation
245         * CPP option: SEAICE_ALLOW_AREA_RELAXATION
246         * runtime flag: SEAICE_tauAreaObsRelax
247      2. modified global mean cost imbalance code: CPP option
248          ALLOW_SSH_GLOBMEAN_COST_CONTRIBUTION
249    o another iteration on solve_*diagonal.F
250       Make choices independent of AUTODIFF
251       Default will be the adjoinable vectorized version.
252       Alternative choices are:
253       * non-adjoinable original version with low memory footprint:
254         #define SOLVE_DIAGONAL_LOWMEMORY
255       * still adjoinable but does not vectorize (k as inner-most loop):
256         #define SOLVE_DIAGONAL_KINNER (keeping SOLVE_DIAGONAL_LOWMEMORY undef)
257    o testreport
258     - add option to use a home made wrapper around "make"
259     - remove MITGCM_IEEE env. variable (no longer active)
260    o pkg/shelfice
261     - improve computation of friction velocity for velocity dependent
262       exchange coefficients: include velocities into SHELFICEBoundaryLayer
263       block to average velocities vertically
264     - add TAF store directives for SHI_ALLOW_GAMMAFRICT
265    o Modify diagonal solvers, now three versions (upon request):
266      #ifndef SOLVE_DIAGONAL_AUTODIFF
267        1. default version (dating back a while ago)
268      #else /* def SOLVE_DIAGONAL_AUTODIFF */
269      # ifdef SOLVE_DIAGONAL_KINNER
270        2. adjoinable version with k-innermost loop (G. Forget)
271      # else
272        3. adjoinable vectorized version of 2.
273      # endif
274      #endif /* SOLVE_DIAGONAL_AUTODIFF */
275      All flags are currently set within routines, but could/should be moved to CPP-options.
276      Array bounds for 1. are as before, for 2.,3. cover the entire domain
277      (could be changed for 1. too).
278    o verification/lab_sea (fwd):
279      - update the 4 fwd lab_sea test experiment: no longer SEAICE_GROWTH_LEGACY,
280        use 7 categories (except hb87), new solve4temp params (except salt_plume),
281        constant salinity (=4) or variable salinity (salt_plume) done through
282        SItracer.
283    o pkg/seaice:
284      - rename parameters: SIsalFrac to SEAICE_saltFrac & SIsal0 to SEAICE_salt0;
285      - remove old parameters ( SEAICE_freeze, SEAICEturbFluxFormula, SEAICE_gamma_t,
286         SEAICE_gamma_t_frz, SEAICE_availHeatTaper & SEAICE_availHeatFracFrz)
287        from SEAICE_PARMS.h ; still need to fix seaice_cost_sst.F (broken when
288        SEAICE_freeze got retired) but already better than previously with
289        SEAICE_freeze=123456.7 deg.C;
290      - move setting of facOpenGrow/Melt from SEAICE_INIT_FIXED to SEAICE_READPARMS
291        (safer multi-threaded setting); always set SEAICEuseEVP;
292      - setting of ocean-ice turb. flux coeff: moved from SEAICE_CHECK to
293        SEAICE_READPARMS & SEAICE_INIT_FIXED (this fixes wrong summary report);
294        stop if multiple specifications for the same coeff; make sure default
295        SEAICE_mcPheePiston is compatible with drF(1) & deltaT.
296    o pkg/obcs:
297      - allow to switch to upwind 1rst order advection scheme for the advective
298        flux computation at the open-boundary; disabled for adjoint built.
299    o pkg/ptracers:
300      - rename PTRACERS_RESTART.h -> PTRACERS_START.h
301      - rename ptracers_fields_blocking_exchanges.F -> ptracers_fields_blocking_exch.F
302      - add parameter to decide when to start a tracer; use internal flag to
303        know which tracer to step-forward; switch this internal flag at the top
304        of forward_step.F (new S/R PTRACERS_SWITCH_ONOFF); for now, not enabled
305        for adjoint built.
306    o pkg/seaice:
307      - add SEAICE_SIZE.h anywhere in the code where SEAICE.h is included ;
308      - move MULTDIM declaration and setting from SEAICE.h to SEAICE_SIZE.h ;
309      - keep experiment offline_exf_seaice truly single category (set MULTDIM=1).
310    o pkg/ecco:
311      - fix writing of output file DiagnosCost_ClimSalt/Theta
312        and DiagnosCost_DriftSalt/Theta (if multi-tiles per proc).
313    o pkg/seaice:
314      - add missing initialisation of COR_ICE array in dynsolver.F
315      - merging SEAICE_MULTICATEGORY define and undef cases. Now the same code is
316        compiled either way, and is tested in all exps (multidim was only tested
317        in lab_sea ad before).
318      - cosmetic change to prepare for future addition of ITD. no change to results.
319        no defaults change.
320      - added run time param SEAICE_multDim (7 for SEAICE_MULTICATEGORY, 1 otherwise).
321      - by lack of adequate verification experiments, I further used custom versions
322        of global_ocean.cs32x15 to test multicat or not, with pickup or not. All
323        should be correct.
324      - avoid recomputations in ad.
325    o array initialisation in adjoint mode:
326      1) pkg/mom_common/mom_calc_ke.F:
327        add full array initialisation of KE inside mom_calc_ke.F (ALLOW_AUTODIFF_TAMC):
328        The S/R which calls MOM_CALC_KE initialises KE but in some recomputation
329        part this initialisation is gone, resulting in Floating Point Exception
330        (caught by open64 compiler with debug option).
331      2) model/src/convective_weights.F
332        set output convectCount over the full array range (instead of doing
333        an update): this fix a similar issue when called within recomputation (adjoint)
334        which could by-pass the initialisation (normally done in the caller S/R).
335    o pkg/seaice:
336      - final version of turbulent flux params, as agreed at MIT ice meet:
337           SEAICE_mcPheePiston (default is ~ 0.000875)
338           SEAICE_mcPheeTaper (default is 0.)
339           SEAICE_frazilFrac (defualt is 1.)
340           SEAICE_mcPheeStepFunc (default is false)
341      - changes results at trunction error level
342      - ifdef SEAICE_EXTERNAL_FLUXES, disallow SEAICE_waterAlbedo
343    o added pkg/frazil:
344      - see frazil_description.tex for details
345      - verification experiment is global_with_exf/input.yearly; changes output.yearly.txt
346    o pkg/shelfice/shelfice_thermodynamics.F
347      - fix exponents for velocity dependent exchange coefficients: change
348        from 2/3(=0) to 0.66666666666666667
349      - move computation of velocity dependent exchange coefficients into
350        separate loop, so that it applies to both thermodynamics
351      - move some divisions by constants out of loops
352    
353    checkpoint63j (2012/02/16)
354    o pkg/seaice:
355      - overhaul of seaice_summary.F after feb 2012 clean-up of seaice_growth.F etc.
356      - SItracer:  added run time params, and allow coupling to ocn salinity.
357    o pkg/seaice: remove (almost) all divisions by constants within loops
358      in seaice_growth.F and seaice_solve4temp.F, this changes (only) the cg2d
359      results of global_ocean.cs32x15.seaice from 16 to 11 digits (but only
360      those, caused by 1/QI -> recip_QI) -> update output.seaice.txt,
361      output_adm.seaice_dynmix.txt and also lab_sea: output_adm.evp.txt
362    o pkg/seaice :
363      - simplify McPhee tapering, and allow to use it with SEAICEturbFluxFormula
364        = 1 or 2, using newly added run time parameter SEAICE_availHeatTaper.
365      - fix d_AREAbyATM, d_AREAbyOCN, d_AREAbyICE diags I broke in r1.148.
366      - add permanent SItflux diag that corresponds to TFLUX but includes
367        ice+snow. Hence SItflux-TFLUX should match the ice+snow heat budget.
368      - allow activation/testing of a fix for suspected missing term in
369        ocn-ice heat budget (to be confirmed). To test this, you want to
370        undef SEAICE_DISABLE_HEATCONSFIX, and then set the run time param
371        SEAICEheatConsFix to .TRUE. that also allows the 'SIaaflux' diagnostic.
372      - no change in results, fwd or ad.
373    o global_ocean.cs32x15/results: 3 changes following from the pkg/seaice commit below:
374      - switch to variable freezing point.
375           Results change : cg2d -> 1 digits; ad -> 3-6-6 digits.
376      - bug fix : the sublimation term that was missing is now activated.
377           Results change : cg2d -> 2 digits; ad -> 8-6-6 digits.
378      - bug fix : flooding sign term for SIsal0.NE.0.
379           Result change : cg2d -> 8 digits; ad -> 11-12-9 digits.
380    o pkg/seaice:
381      - unified freezing point treatment : the old SEAICE_VARIABLE_FREEZING_POINT
382        is now the default, and the old default constant freezing point is recovered
383        with SEAICE_tempFrz0    = -1.96,
384             SEAICE_dTempFrz_dS = 0.,
385      - retire SEAICE_freeze (= the old way of specifycing the constant freezing point)
386      - remove ALLOW_SEAICE_FLOODING brackets; run time switch is already there.
387      - bug fix (thanks to M. Losch) : the sublimation term that was missing is now
388        activated. To reproduce old results with this bug define SEAICE_DISABLE_SUBLIM.
389      - bug fix (silly me) : flooding sign term (seaice_growth.F r 1.149line 1211)
390        was wrong for SIsal0.NE.0. Changes cs32x15 results (see above item for detail).
391      - bug fix (thanks to O. Jahn) : area loss for melting  got messed up in
392        seaice_growth r149 for legacy branch (no results change).
393      - introduce SEAICE_CAP_SUBLIM : caps sublimation heat flux in solve4temp (code
394        from I. Fenty).
395      - results did not change except for global_ocean.cs32x15, mostly due to the
396        switch to variable freezing point (see above item for detail).
397    o pkg/thsice:
398      - fix and simplify interface to salt_plume pkg ; diagnose directly amount of
399        seawater freezing in thsice_calc_thickn (not used).
400    o pkg/seaice: turbulent flux term specification via run time params.
401      - replace CPP switches with run time switches to facilitate testing
402      - retired CPPs : MCPHEE_OCEAN_ICE_HEAT_FLUX,
403                       GRADIENT_MIXED_LAYER_TURBULENCE_FACTOR
404      - added runtime parameter : SEAICEturbFluxFormula
405      - move Mcphee constants to SEAICE_PARAMS.h
406      - seaice_readparms.F : read turbulent flux term params (SEAICEturbFluxFormula;
407                 SEAICE_availHeatFrac/Frz, or SEAICE_gamma_t/_frz if apply);
408                 remove seaice_summary call (moved to seaice_init_fixed)
409      - seaice_init_fixed.F : set SEAICE_availHeatFrac/Frz depending on
410        SEAICEturbFluxFormula, and seaice_summary call (moved from seaice_readparms)
411      - seaice_summary.F : add missing report of read turbulent flux term set up
412                           and SITRACER.
413      - seaice_check.F : check range; inform and stop if retired CPPs are used
414                         (incl. SEAICE_AGE).
415      - seaice_growth.F : unified use of SEAICE_availHeatFrac/Frz, without
416             CPP switch, same computation as before for the different options.
417      - change results at the truncation level.
418    o pkg/seaice:
419      - remove un-used parameters LAD & MAX_TICE ; add new run-time parameters:
420        useMaykutSatVapPoly (default=F), postSolvTempIter (default=2) and
421        SEAICE_wetAlbTemp (default=-1e-3). Remove option SEAICE_SOLVE4TEMP_LEGACY.
422      - update verification/*/input*/data.seaice:
423        to reproduce previous results with former #defined SEAICE_SOLVE4TEMP_LEGACY
424        code, set useMaykutSatVapPoly=T & postSolvTempIter=0 ;
425        and to reproduce previous results with former non-SOLVE4TEMP_LEGACY code,
426        set SEAICE_wetAlbTemp=0 & SEAICE_snowThick=0.
427    o pkg/seaice/seaice_solve4temp.F (SOLVE4TEMP_LEGACY):
428      - remove LEGACY code for solving for tsurf (A1,A2,A3) but maintain the same
429        algorithm (same choice: useMaykutPolySatVap=T, postSolvTempIter=0);
430        difference in results only due to machine truncation.
431      - remove MAX_TICE (tsurf is always =< TMELT anyway); keep MIN_TICE if using
432        MaykutPolySatVap; keep MIN_LWDOWN.
433      - adapt SEAICE_MODIFY_GROWTH_ADJ code (untested) to non-legacy formulation.
434      - update output of verification exp. lab_sea (4 fwd: 11 cg2d digits except hb87,
435        + 3 AD: 6 digits except evp) and offline_exf_seaice.seaice (12 digits).
436    o pkg/salt_plume:
437      - isolate saltPlumeFlux array exch into a specific S/R called from
438        do_oceanic_phys.F
439      - add interface to pkg/salt_plume (filling of saltPlumeFlux) in pkg/thsice.
440    o verification:
441      - move untested set-up to MITgcm_contrib/verification_other.
442    o pkg/seaice:
443      - retire old way of SEAICE_AGE. Now replaced with ALLOW_SITRACER.
444    o pkg/seaice:
445      - seaice_solve4temp.F (keeping results unchanged):
446        * add 2 future run-time params to select which saturation vapor pressure
447          formula is used and how post-iteration fluxes are set.
448          Temporary set these 2 params according to option SOLVE4TEMP_LEGACY;
449        * New piece of code (not used) to update surf. atmos. heat flux F_ia using
450          the linearized expression to stay consistent with tsurf finding.
451      - seaice_freedrift.F avoid floating exception in sqrt(y) since y=sqrt(x*x)-x
452        can be < 0.
453    o pkg/seaice/seaice_solve4temp.F (SOLVE4TEMP_LEGACY undef):
454      - remove from F_ia (and from it's derivative dFiDTs1) the contribution of
455        conductive heat flux F_c , and add it explicitly when updating tsurf as
456        solution of: Fc = Fia + d/dT(Fia - Fc) *delta.tsurf
457        so that now F_ia has a consistent meaning through the entire routine.
458        This causes differences at truncation level: update output of fwd exp.
459        global_ocean.cs32x15.seaice.
460    o pkg/seaice:
461      - lots of editing/cleaning in seaice_solve4temp.F + better documentation
462        of arrays, sign/direction of fluxes; no effect on results.
463      - replace hard coded 273.16 (=previous value of celsius2K) by celsius2K
464        in seaice_budget_ocean.F & seaice_solve4temp.F (SOLVE4TEMP_LEGACY part);
465        note: this should have been done before changing celsius2K default.
466      - to keep results unchanged, add back old value of celsius2K in verification
467        exp. input*/data : lab_sea (AD), offline_exf_seaice (fwd+AD) & seaice_obcs
468      - replace hard coded seawater freezing temp in seaice_solve4temp.F (part
469        SOLVE4TEMP_LEGACY) of 271.20 (=previous value of celsius2K + default
470        value of SEAICE_freeze) by celsius2K+SEAICE_freeze so that seawater
471        freezing temp is consistent with value in seaice_growth.F ; this causes
472        differences at machine truncation level: update lab_sea AD output (3/4).
473    o pkg/seaice:
474      - mask (in exf_init_fixed.F) atemp,aqh,evap,precip,runoff,lwflx,areamask
475        and climsst/sss even when using seaice (to prevent calculation that might
476        use SST on land); does not affect any verification exp.
477      - apply mask to taux,tauy (in seaice_get_dynforcing.F); update output
478        of lab_sea.fd & lab_sea.hb87 and global_ocean.cs32x15.seaice_dynmix.
479    o pkg/seaice/seaice_growth.F: add mask to avoid non-zero ice thickness
480      over land (non-legacy code)
481    o vectorize salt_plume package:
482      - add extra code to salt_plume_frac and salt_plume_tendency_apply_s
483      - this code computes plumebk everywhere (also over land), thus requires
484        code to avoid divisions by zero and catch the case of kLev=Nr.
485      - efficiency of salt_plume_frac is still sub-optimal
486    o tools (genmake2):
487      - fix makefile NAME specification (option: -makefile NAME) by adding
488        "-f $MAKEFILE" in few places where it was missing including makedepend
489        command (contribution from Paul).
490    
491    checkpoint63i (2012/01/24)
492    o model/src:
493      - add factorized versions of some EOS code to find_rho.F,
494        define USE_FACTORIZED_EOS to turn it on (default for TARGET_NEC_SX)
495    o model/src:
496      - add celsius2K to namelist PARM01; remove unused recip_rhoNil from PARAMS.h;
497      - change default celsius2K from 273.16 to 273.15
498      - to keep results unchanged, add back old value of celsius2K in verification
499        exp. input*/data : aim.5l_cs, 1D_ocean_ice_column, lab_sea (fwd),
500         global_ocean.cs32x15(seaice) & cpl_aim+ocn(input_atm).
501    o model/src: add a little initialisation trick to find_rho.F and find_alpha.F
502      to make TAF generate vectorizable code
503    o pkg/seaice/seaice_evp.F: add code (copied from CICE) that avoids underflows.
504       Turn on by defining SEAICE_EVP_ELIMINATE_UNDERFLOWS. Most compilers
505       have flags that do this more efficiently.
506    o pkg/diagnostics/diagstats_calc.F
507      - for TARGET_NEC_SX fix the treatment of the scaling factor tmpFac=scaleFact
508    o pkg/obcs (with exch2):
509      - derive OB indices in overlap region from OB-InsideMask (in obcs_init_fixed.F)
510        and remove code (in obcs_readparms.F) which was based on EXCH of indices
511        (through buffer) and did not account for exch2 (e.g., CS-grid) topology.
512    o pkg/exf and seaice exp:
513      - change offline_exf_seaice.seaicetd test exp. to use default DIFF1 value (=0)
514        so that switching off area & heff advection flags does not affect results.
515      - change default EXF_LWDOWN_WITH_EMISSIVITY to #define in EXF_OPTIONS.h
516      - keep exp. seaice_obcs & 1D_ocean_ice_column(ad) unchanged (using #undef
517        EXF_LWDOWN_WITH_EMISSIVITY) and, using pkg/exf default emissivities, update
518        results of verification experiments: 1D_ocean_ice_column(fwd),
519        global_ocean.cs32x15.seaice(fwd+ad) & seaice_dynmix(ad), lab_sea (all 8)
520        and offline_exf_seaice (all 4).
521    o pkg/seaice:
522      - remove array YNEG, RIVER, TMIX (replaced by local var) from common block;
523        remove also areaNm1 & hEffNm1 when SEAICE_GROWTH_LEGACY is undef.
524      - fix bug: areaNm1 & hEffNm1 are needed in seaice_growth (SEAICE_GROWTH_LEGACY)
525        but were not filled when resp. SEAICEadvArea=F & SEAICEadvHeff=F and
526        not multi-dim advection;
527      - fix seaice_growth.F to compile with both SEAICE_GROWTH_LEGACY and
528        SHORTWAVE_HEATING #undef.
529    o optim: make Makefile more robust (?)
530    o pkg/obcs:
531      * fix treatment of obcs_read_pickup for TAF
532    o pkg/shelfice:
533      * add missing initialisation of num_shifwflx
534      * new adjoint verification exp. for isomip
535      * change Prandtl and Schmidt numbers from generic formulations
536        (in terms of model diffus. and visc.) to separate runtime
537        parameters, with Holland and Jenkins (1999) default values.
538    o pkg/exf (interpolation):
539      - extended input field (2 rows) near the N & S poles:
540        * fill in with the symetric value (when even Nb of data in longitude)
541        * add average value at the poles only for scalar quantities ; for vector
542          component interpolation, skip the averaging and keep duplicated values,
543          unless the 2 components have same location (uvInterp=T) in which case
544          interpolate the 2 components together using S/R EXF_INTERP_UV.
545      - new S/R EXF_INTERP_UV to interpolate the 2 components of a vector field
546        together: this allows to account properly for local orientation when
547        averaging at N & S pole.
548      - add CPP option EXF_USE_OLD_INTERP_POLE to recover old results regarding
549        exf-interpolation near N & S poles. Undef by default.
550      - add debug check/print on 1rst iter if debugLevel >=2.
551    o pkg/exf:
552      - change masking flags definition (no longer "parameter"), put them in
553        common block and set them in S/R EXF_INIT_FIXED.
554      - change recognized masking flag from s,u,v to c,w,s since the mask
555        to use (maskC,W,S) depends on position on model grid and has little to
556        do with scalar/vector difference; fix masking if using P-coordinates.
557      - fix masking of wind-stress (was wrong if interpolated or read on A-grid)
558        and update results of exp. global_with_exf (x2).
559      - fix setting of zenith-angle table when SHORTWAVE_HEATING is undef.
560    o pkg/obcs
561      - S/R obcs_calc_stevens: fix a small bug (gammat -> gammas where appropriate)
562    o pkg/exf (interpolation):
563      - assume periodicity in X only if input field cover full longitude range.
564      - improve search for lat. index (supposed to be faster, in ~log2(ny) steps,
565        and should vectorise).
566      - fix input lat of the 2 added row (in case we provide N.pole data).
567    
568    checkpoint63h (2011/12/30)
569    o pkg/seaice:
570      - change declaration of UVM from _RL to _RS in order to get B-grid
571        uIce,vIce monitor when _RS = real*4
572    o pkg/offline:
573      - new S/R OFFLINE_RESET_PARMS for resetting main-model params (switch off flags);
574      - compute vertical velocity if not read from file (switch on exactConserv
575        & staggerTimeStep);
576      - fix output of ptracer monitor iter & time for default PTRACERS_monitorFreq.
577    o verification:
578      - update grid-files (in tutorial_held_suarez_cs/input and fizhi-cs-32x32x40/input)
579        with grid-angle generated using "utils/matlab/cs_grid/cubeCalcAngle.m":
580        fix Pb in yG definition @ 2 missing corners (previously yG was averaged);
581      - update output of exp. global_ocean.cs32x15.viscA4 after changing
582        grid-file angles (used here for coriolis-3d);
583      - remove (or gzip) few files not needed to run fizhi-cs experiments.
584    o pkg/exf (vector interpolation):
585      - rotate vector component toward local grid-axis orientation using grid-angles
586        (stored in GRID.h) instead of locally computed rotation angle; keep old code
587        available with exf option EXF_USE_OLD_VEC_ROTATION (undef by default).
588    o pkg/seaice:
589      - allow to compile with exf options ALLOW_ATM_TEMP or ALLOW_DOWNWARD_RADIATION
590        undefined. Fix and remove the stop when ALLOW_RUNOFF is undefined.
591    o pkg/PKG_OPTIONS.h files:
592      - move #include "CPP_OPTIONS.h" just after #include "PACKAGES_CONFIG.h",
593        outside of the #ifdef ALLOW_THISPKG / #endif block.
594      - update verification/*/code/PKG_OPTIONS.h files.
595    o add a verification experiment (offline_exf_seaice/input.seaice) that test
596      the B-grid LSOR solver
597    o pkg/seaice: sort out emissivity and long wave radiation step 2:
598      - add emissivity for snow and ice as new run-time parameters
599        (unfortunately) that default to the corresponding exf values; this
600        changes results in most verification experiments so that for backward
601        compatibility these parameter have to be set explicitly to inconsistent
602        values (ugly);
603      - the exf-flag EXF_LWDOWN_WITH_EMISSIVITY then gets rid off the hard-wired
604        emissivities of 0.97 associated with lwdownloc in S/R seaice_solve4temp
605        until we agree how to handle this bug properly
606    o pkg/exf (interpolation):
607      - add a set of run-time param ({inputfield}_interpMethod), one for
608        each interpolated input field, to select the interpolation method
609        with a value of zero switching off the interpolation;
610      - print interpolation parameters to standard output;
611      - refine exf_check.F accordingly ; stop if USE_NO_INTERP_RUNOFF is defined
612        (to use instead runoff_interpMethod=0 in data.exf).
613      - simplify default setting of interpolation parameters (for all fields,
614        set position to match model grid cell-center position, leading to trivial
615        interpolation in case of regular Lat-Lon grid) and fix for the case of
616        non-uniform delY.
617    o pkg/exf/exf_radiation.F: add the factor ocean_emissivity to lwdown, for
618       within #ifdef EXF_LWDOWN_WITH_EMISSIVITY/#endif. Unless ocean_emissivity=1.
619       this factor is absolutely required, because the lw exitance (= out-going
620       long wave radiation) is emissivity*stefanBoltzmann*T^4 + rho*lwdown,
621       where the reflectivity rho = 1-emissivity for conservation reasons. Once
622       this is established, we can remove the CPP-Flag (if we want to).
623    o pkg/seaice:
624      - qualify a stop statement in S/R seaice_check: EXF_READ_EVAP and
625        ALLOW_BULKFORMULAE are only required if SEAICE_EXTERNAL_FLUXES is defined
626      - sort out emissivity and long wave radiation, step 1: make SEAICE_emissivity
627        what the name implies (and not emissivity*BoltzmannConstant), this means
628        the old default value of 5.5e-8 now means
629        5.5e-8/5.670e-8 = 0.97001763668430343479 as ocean_emissivity in
630        S/R exf_readparms
631      - FV-discretization of the B-grid LSOR solver, turn on with
632        SEAICE_LSRBNEW. This new solver also involves a slight re-organization
633        of the calling routine dynsolver, so that B and C-grid code look a
634        little more alike.
635      - fix index bugs in ostres.F (B-grid code)
636    o pkg/seaice/seaice_ocean_budget.F: change (unused) code to make it look better
637    o pkg/seaice/seaice_readparms.F: make ocean_emissivity*stefanBoltzmann the
638      default for SEAICE_emissivity, if useEXF; requires setting a wrong
639      parameter value in global_ocean.cs32x15/input.seaice/data.seaice for
640      backward compatiblity
641    o model/src: use sigmaR in calc_ivdc
642    
643    checkpoint63g (2011/12/16)
644    o pkg/seaice/seaice_growth.F:
645      fix heat conservation of the coupled ocean-seaice system.
646      when SEAICE_HEAT_CONSERV_FIX is defined, the mismatch of
647      solid vs liquid water treatment is resolved via QNET.
648    o pkg/seaice/seaice_growth.F:
649      add missing term for sublimation in saltFlux, which was breaking conservation.
650    o pkg/seaice/seaice_model.F:
651      Remove this patholigical case treatment in evolution branch,
652      where it is un-necessary and breaks conservation.
653      Update global_ocean.cs32x15/results accordingly for
654      output.seaice.txt output_adm.seaice.txt and output_adm.seaice_dynmix.txt
655    o model/src:
656      useRealFreshWaterFlux: remove masking of EmPmP (using maskInC) in
657      external_forcing_surf.F and apply mask directly in S/R SOLVE_FOR_PRESSURE.
658    o pkg/obcs:
659      modify Stevens boundary conditions so that S/R obcs_calc_stevens computes
660      tendency for temperature and salinity that is then applied to update
661      theta and salt in S/R obcs_apply_ts; this requires proper masking of all
662      horizontal advection and diffusion contributions on the boundary (in
663      S/Rs gad_advection, gad_calc_rhs, gmredi_rtransport, gmredi_calc_diff), and
664      removing the mask in S/R timestep_tracer. The advantage of this approach is
665      that the updated tracer values include contributions from the surface
666      forcing and vertical diffusion.
667      This modification changes exp4.stevens because of vertical diffusion.
668    o model/src:
669      change non-curvilinear grid setting to also work with exch2 + blank tiles:
670      - move delX,delY to new header file (SET_GRID.h) and adjust length to 1rst
671        face dimensions.
672      - new S/R INI_LOCAL_GRID to define model tile-local grid (using same units
673        as delX,delY) and called from S/R INI_CARTESIAN_GRID, INI_CYLINDER_GRID
674        and INI_SPHERICAL_POLAR_GRID.
675      change test-experiment global_ocean.90x40x15:
676      - split the domain in many more tiles (9x4 tiles of 10x10 each);
677      - switch to exch2 and remove 1 blank-tile (but only for MPI test).
678      - update results of both test (std & dwnslp).
679    o pkg/diagnostics/diagstat_calc.F: fix problem with non-initialised halos in
680       tmp-fields for TARGET_NEC_SX at the cost of extra loops and less vectorisation
681    o model/src:
682      - take sigma-coords related code out of update_etah.F into new S/R UPDATE_ETAWS
683        and fix initialisation when using sigma-coords.
684    o model/src:
685     - improve Gael's changes from Jan 14, 2011 "addition of an 'update' of hfacc etc.
686       to their current value at the beginning of forward_step.F": add a new run-time
687       switch "doResetHFactors" (default=false) and use it to do (or not) the resetting.
688     - set doResetHFactors=T in the following test exp:
689        global_ocean.90x40x15/input (rStar) & input.dwnslp (linFS),
690        global_ocean.cs32x15/input.seaice (rStar), hs94.cs-32x32x5/input.impIGW (linFS)
691        and tutorial_global_oce_in_p (nonLinFS in p)
692    o pkg/ecco
693      - added IES cost term
694    o verification/advect_xz
695      - scale down the depth by 1/100 (from 200 km to just 2.km)
696      - add secondary test using divergent flow, r-star and implicit vertical advection.
697      - add note (check_conserve_TS.txt) and matlab script to check global
698        conservation of T & S with NonLin-FreeSurf and Adams-Bashforth.
699    o pkg/rbcs:
700      - add missing relaxUFile & relaxVFile in namelist (in rbcs_readparms.F).
701    o pkg/obcs (Stevens BCs):
702      - fix various problems in the phase speed computations of the Stevens
703        boundary conditions:
704        - sign error for western and southern boundaries,
705        - time tendencies were underestimated by factor of dTracerLev and some just
706          zero (for multidim advection schemes) -> now estimate time tendencies
707          from difference between previous (n) time level and the one before (n-1);
708          this requires storing a field per tracer per boundary, also in the pickup
709          files.
710        - replace deltaTmom in cflMer/Zon computation with dTracerLev
711        - set default phase velocity to cflMer/Zon
712      - update verification experiment exp4.stevens
713    o pkg/generic_advdiff (implicit_r):
714      - fix implicit vertical advection conservation with AB and/or NonLin-FreeSurf
715        (remove Tr*d/dz(w) in gad_implicit_r.F and add it in gad_calc_rhs.F);
716      - fix implicit vertical diffusion or advection with NonLin FreeSurf
717        (was using current recip_hFacC instead of future recip_hFacC): set future
718        recip_hFac in thermodynamics.F and pass & use it in all vertical implicit
719        solver S/R ;
720      - fill diagnostics of vertical advective fluxes (computed from tendency)
721        when using implicit vert. advection;
722      - update output of exp that uses NonLin-FreeSurf & implicit vertical diffusion:
723         global_ocean.90x40x15 (fwd+AD), global_ocean.cs32x15 (4 fwd +4 AD),
724         tutorial_global_oce_in_p (fwd), tutorial_tracer_adjsens (AD)
725         and cpl_aim+ocn (used in ocean); to be fixed: bottom_ctrl_5x5.
726    o pkg/diagnostics:
727      - add diags for T & S tendency which goes through Adams-Bashforth.
728    
729    checkpoint63f (2011/11/30)
730    o pkg/obcs/obcs_calc_stevens.F:
731      - join some loops to reduce number of if-statements
732      - fix a bug in code for northern and southern boundaries.
733    o pkg/seaice/seaice_init_varia.F
734      - undo resetting UVM=0 that has slipped in unnoticed in r1.49 and
735        caused zero ice-velocities for the B-grid code
736    o pkg/seaice/seaice_init_fixed.F
737      - fix a bug in the initialisation of the second metric terms
738        k2AtC and k2AtZ: k2AtC was set to the value of k2AtZ and k2AtZ was 0.
739      - this affects all seaice configurations with useCurviLinearGrid = .true.
740        and SEAICEuseDynamics = .true. (default) and SEAICEuseMetricTerms
741        = .true. (default)
742      - the only verification experiment affected is global_ocean.cs32x15:
743        icedyn, seaice, and seaice_dynmix (AD)
744    o pkg/thsice/thsice_diagnostics_state.F
745      - only for TARGET_NEC_SX: initialise all of tmpFld, so that overlap does
746        not contain garbage that can lead to surprises in diagstats_calc.F
747    o model/src:
748      - move bi,bj loops inside INTEGR_CONTINUITY ;
749      - call INTEGR_CONTINUITY directly from forward_step.F
750        (previously called from momentum_correction_step.F)
751      - call UPDATE_ETAH from integr_continuity.F and update initialise_varia.F,
752        forward_step.F and pkg/ecco/the_main_loop.F
753    o model/src/do_oceanic_phys.F:
754      - reset addMass to zero only if useICEFRONT ;
755      - separated k-loop for rhoInSitu calculation ;
756      - add 2 diagnostics for wVel*delta^k(Rho) at constant pressure (= WdRHO_P)
757        and at constant T,S (= WdRHOdP);
758      NOTE: change diagnostics WRHOMASS : this is now simply the Vertical transport
759        of In-Situ Density (Anomaly) (=wVel*rho^bar-k) (previously was Vertical
760        transport of locally-referenced potential density);
761        to recover old diag: (WRHOMASS)_old = (WRHOMASS)_new -1/2 * (WdRHOdP)
762    o gluemnc:
763      - replace ncrcat with ncks when adding variables to *.glob.nc
764      - change the way variables without record dimensions are handled so that
765        files that have variables with and without record variables can be glued:
766        add a record dimension with a new unique name to be able to differentiate
767        between variable with and without a-prior record dimensions. Remove
768        this record dimension before adding the variable to the *.glob.nc file.
769        This procedure automatically works also for grid.*.nc files that do not
770        have any record dimension.
771    o verification/cpl_aim+ocn:
772      - generate new reference output on baudelaire (gfortran, mpich2) (previously
773        from old aces-grid cluster, ao + ifort) and update 'run_cpl_test' script.
774    o pkg/obcs/obcs_calc_stevens.F:
775      - add code for northern and southern boundaries.
776      - reorder some loops to save some operations and so that drFBar can be scalar
777    o model/src:
778      - re-arrange extrapolation calculation in Adams-Bashforth S/R (affects machine
779        truncation) and add diagnostics for Adams-Bashforth tendency increment.
780      - update test-exp. AD output:
781        1D_ocean_ice_column, bottom_ctrl_5x5, lab_sea.noseaicedyn, obcs_ctrl;
782      and FWD output: exp4 (x3), fizhi-cs-32x32x40, fizhi-cs-aqualev20,
783        front_relax (x3), global_ocean.90x40x15 (x2), global_ocean.cs32x15 (x5),
784        global_ocean_ebm, ideal_2D_oce, internal_wave, isomip (x3), lab_sea (x4),
785        matrix_example, MLAdjust (x5), natl_box (x2), tutorial_advection_in_gyre,
786        tutorial_global_oce_in_p, tutorial_global_oce_latlon and
787        tutorial_plume_on_slope.
788    o pkg/diagnostics/diagstats_calc.F: add special code for TARGET_NEC_SX
789      that vectorises. This code uses 3 extra 2D fields, F90 array assignments
790      and F90 intrinsic routines SUM, MINVAL, MAXVAL, but since TARGET_NEC_SX
791      does not even come with an F77 compiler anymore, this should not be
792      a limitation
793    
794    checkpoint63e (2011/11/06)
795    o pkg/seaice adjoint of LSR:
796      - substantially rework STORE dirs.
797      - add new flag SEAICE_LSR_ADJOINT_ITER and parameter SOLV_MAX_FIXED
798        this flag will do SOLV_MAX_ITERS but only store SOLV_MAX_FIXED fields
799        and only perform SOLV_MAX_FIXED adjoint iters.
800        If flag SEAICE_LSR_ADJOINT_ITER is undef-ined, the store in the iteration
801        always goes to same record, meaning that the last forward field will be
802        the one used in the adjoint - an approximation.
803      - now produces non-zero LSR-related gradients, and acceptable gradients for
804        An's zonal (x-z) test case (to be checked in)
805      - lab_sea: produces acceptable gradients for lab_sea with forward/backward LSR
806        (but these are screwed up by the thermodynamics in the first place);
807        reduce from 4 to 3 timesteps to avoid t.d. issue as temporary solution;
808        output_adm.txt also reflects changes to seaice_lsr
809      - global_ocean.cs32x15:
810        * the "default" input_ad.seaice has been re-defined to always exclude dynamics
811          (output_adm.seaice.txt was updated)
812        * new input_ad.seaice_dynmix tests a forward LSR / backward free-drift
813          (output_adm.seaice_dynmix.txt)
814    o test-exp. exp4+stevens:
815      - switch off pTracers and nonHydrostatic (restart problems with NH); update output
816    o pkg/seaice (lsr solver):
817      - put coriolis term into FORCEX,Y (as in seaice_evp.F; previously in rhsU,V only);
818        update output (change truncation) of FWD test exp lab_sea & global_ocean.cs32x15
819      - fix SEAICEuseFREEDRIFT for new OBCS version (ndef OBCS_UVICE_OLD)
820      - new parameter "LSR_mixIniGuess" allows (if=2,4) to mix free-drift solution
821        into initial guess for linearised solver; use weight ~ (1/err)^2,4.
822      - compute (with new S/R) and print initial (+ free-driff sol. if available)
823        and final residual of linearised system.
824    o pkg/pp81: add diagnostics for vertical eddy viscosity and diffusivity
825      (requires new subroutines pp81_init_fixed.F/pp81_diagnostics_init.F)
826    o pkg/obcs: Stevens BCs (still only for east and west)
827      - fix Stevens BCs by using intermediate velocities of previous
828        time step as "baroclinic" contribution rather velocity of one grid cell
829        inside the boundaries; more consistent but makes the entire treatment
830        more complicated, requires new pickup files and two new S/Rs:
831        obcs_copy_uv_n and obcs_save_uv_n
832        keep old version with flag OBCS_STEVENS_USE_INTERIOR_VELOCITY
833        (undefined by default)
834      - silently move computation of some grid factors into separate loops to
835        save some recomputations
836      - add a hack for non-linear free surface
837      - add a verification experiment to exp4 that tests this code
838    o make gluemnc/xplodemnc work with (moron) non-GNU shell tools
839    
840    checkpoint63d (2011/10/25)
841    o pkg/obcs + seaice-dynamics:
842      - new implementation calls OBCS_APPLY_UVICE (in seaice_dynsolver.F) before
843        solving for uIce,vIce and prevent SEAICE_LSR or SEAICE_EVP to modify OB
844        values (consistent with an implicit method).
845      - add option OBCS_UVICE_OLD (in OBCS_OPTIONS.h, defined by default) to
846        return to older implementation (same results as before); note that none of
847        the "experimental" OBCS_SEAICE options are implemented in the new version.
848      - switch test exp. seaice_obcs to use new version (update output).
849    o pkg/seaice:
850      - add few stop (B-grid & CS-exch, B-grid & obcs, AUTODIFF & SEAICE_maskRHS)
851      - add parenthesis in Water-Ice drag calculations (evp & lsr);
852      - in seaice_lsr.F, simplify and fix AA3 setting in case sNx or sNy=1;
853        and fix case SEAICE_waterDrag=0 (but unstable if no or little seaice)
854      - update output of test exp lab_sea that uses evp or lsr (fwd+ad)
855        and global_ocean.cs32x15 (icedyn & seaice fwd+ad).
856    o pkg/layers:
857      - Include potential density as new coordinate (Thanks to David Munday)
858    o pkg/dic:
859      - Remove subroutine CALC_PCO2_APPROX_CO3 from carbon_chem.F and add
860        carbonate computation/output to CALC_PCO2_APPROX
861    o pkg/generic_advdiff
862      - make TAF generate code that vectorizes:
863        gad_dst3fl_adv_*.F, gad_u3c4_impl_r.F
864    o model/src:
865      - improve vectorization also for adjoint code of
866        solve_tridiagonal and solve_pentadiagonal. As this requires up to
867        5 new 3D-fields, this code is only turned on for the combination of
868        ALLOW_AUTODIFF_TAMC and TARGET_NEC_SX. Also remove error message
869        for singular matrix check (only for TARGET_NEC_SX).
870      - remove hard-wiring of CPP-flag ALLOW_SOLVERS_KLOOPINSIDE to
871        ALLOW_AUTODIFF. This flag now needs to be set outside of
872        solve_tri/pentadiagonal.F
873    o pkg/exf:
874      - fix previous modif in exf_readparms.F (revision 1.66: treatment of
875        optional namelist EXF_NML_OBCS).
876      - add many debug-print (to trace down where pkg/cal error msg comes from)
877    o pkg/mom_vecinv/mom_vi_hdissip.F
878      - rearrange loops so that vectorization is improved and in particular
879        the adjoint routine vectorizes. The code is a little longer now, but I
880        think easier to read.
881        Note: CPP-flag MOM_VI_ORIGINAL_VISCA4 is not tested.
882    o pkg/seaice:
883      - allow to specify initial seaice velocity from files (uIceFile,vIceFile)
884    o pkg/exch2:
885      - alternative code (without tile x tile matrix) for cumulated (global) sum;
886        used as default; keep using matrix version in adjustment.cs-32x32x1.
887    o tools/build_options:
888      - after merging some MPI and/or multi-threads specific optfiles so that
889        the modified default optfile support both built (using genmake2 -mpi
890        for the MPI built, using genmake2 -omp for OpenMP built),
891        move now obsolete optfiles to tools/build_options/unsupported/
892       (add copy of email sent to support list in doc/optfiles_changes.txt)
893    
894    checkpoint63c (2011/09/28)
895    o pkg/ebm:
896      - fix ebm_zonalmean.F for several procs in Ydir (nPy > 1); update output of
897        test exp. global_ocean_ebm (affects machine truncation, 12 digits for cg2d)
898    o pkg/seaice (SItracer pickup)
899    * Simple code for pickup of SItracer fields (#define ALLOW_SITRACER)
900      To be done:
901      - thorough testing of missing fields in S/R seaice_read_pickup
902      - thorough matching between generic tracers and specific fields used
903        (e.g. volume-weighted age, area-weighted age, salinity, ...)
904    o pkg/grdchk:
905      - all procs calculate and print finite-difference gradient (for testreport)
906      - change description output used by testreport;
907      - AD testing: also compare and report Finite-difference gradient;
908        => update all output_adm*.txt
909    o test exp. global_ocean_ebm:
910      - switch back useRealFreshWaterFlux (no problem anymore with run-off);
911        and turn on exactConserve; update (fwd) output.
912    o pkg/seaice (LSR):
913      - print to STDOUT number of solver iterations at SEAICE_monFreq interval.
914      - modify solver to deal cleanly with u/v switch at face edges (CS-grid):
915        * identical results with non-CS topology (but save up to half of EXCH calls)
916        * no much changes in cs-32 verification tests since no ice at face edges
917         (differences due to convergence criteria, since nb of iterations changed)
918        * expect some differences on lat-lon-cap grid.
919        update FWD results of global_ocean.cs32x15 test exp. (icedyn & seaice)
920    o pkg/exch2:
921      - add new CPP option to disable Cumul-Sum matrix (to save storage when using
922        many tiles); until alternative coding is added, just add a stop.
923    o pkg/kpp:
924      - move ptracer/salt correction to KPP diffusivity from calc_3d_diffusivity.F
925        to S/R KPP_CALC_DIFF_PTR (+ add tracer-index to argument list).
926    o optfiles:
927      - merged few MPI specific (*+mpi*) and multi-threads specific (*+mth) optfiles
928        into corresponding standard one, which now support different build:
929        (when using "genmake2 -mpi" for MPI built, "genmake2 -omp" for OpenMP built)
930      - add "darwin_amd64_gfortran" optfile (initially from Constantinos, tested by Gael)
931    o pkg/obcs (seaice):
932      - add missing EXCH for uIce,vIce after applying OBCS;
933      - remove S/R EXF_SWAPFFIELDS_X/Y , disable S/R EXF_SET_OBCS_X/Y by adding
934        argument = number of levels to S/R EXF_SWAPFFIELDS_XZ/YZ and S/R
935        EXF_SET_OBCS_XZ/YZ ; update obcs_exf_load.F;
936      - fix EXF_SET_OBCS_XZ/YZ for multi-threaded (assuming loaded arrays are shared)
937      - verification exp. seaice_obcs: split domain in 2 tiles ; add SIZE.h_mpi
938        and eedata.mth for MPI and mutlti-threaded testing.
939    o pkg/flt:
940      - make FLT EXCH working with multi-threads (and MPI + multi-threads);
941      - use buffer for floats IO (trajectories & profiles); size set in FLT_SIZE.h;
942      - fix pickup and trajectories + profiles output with multi-threads;
943      - add parameter to select group of fields to write along trajectory and
944        profile (default unchanged);
945      - only call PORT_RAND* function when flt_noise <> 0;
946      - add multi-threaded test for verification exp. flt_example.
947    o eesupp/src:
948      - fix S/R ALL_PROC_DIE for MPI+multi-threads.
949      - USE_OMP_THREADING: check that number of threads (from eedata) matches
950        actual number (from env.var. setting).
951    o pkg/ebm:
952      - fix multi-threading in ebm_area_t.F ; clean-up EBM.h header file.
953      - add multi-threaded test for verification exp. global_ocean_ebm
954    
955    checkpoint63b (2011/08/29)
956    o pkg/ebm:
957      - fix sign of runoff;
958      - update directly forcing fields (Qnet,EmPmR) to use standard
959        external_forcing_surf.F (remove ebm_forcing_surf.F);
960      - avoid loading forcing fields a 2nd time (1rst time from ini_forcing.F);
961      - set either tauThetaClimRelax (in data) or tauThetaZonRelax (in data.ebm)
962        and apply relaxation towards corresponding SST field (2-D map or ZonAver).
963      - update global_ocean_ebm parameters file data and update output (fwd+ad).
964    o verification/matrix_example:
965      - split domain in 8 tiles (2x4); add SIZE.h_mpi and eedata.mth for
966        MPI and mutlti-threaded testing.
967    o pkg/matrix:
968      - change name of S/R MATRIX_INIT to S/R MATRIX_INIT_VARIA ;
969      - fix for multi-tiles (add bi,bj indices to exp/impMatrixCounter);
970      - fix for multi-threaded (remove DATA statement);
971      - use standard DIFFERENT_MULTIPLE function;
972      - add MATRIX_OPTIONS.h
973    o verification/matrix_example:
974       To allow to split the domain in several tiles, change the domain size
975        from 31x31 to 32x32 by adding 1 row (on Southern side) + 1 column (on
976        Western side) of land points.
977    o (*_)write_pickup:
978      - fix few bugs in mypackage_read/write_pickup.F
979      - in MDS_WR_METAFILES calls, replace "myTime" by a local copy into
980        array of length 1 (was caught by compiler syntax-check).
981    o pkg/diagnostics (velocity potential solver):
982      - fix initialisation of main diagonal matrix (for overlap values)
983    o tools/build_options:
984      - towards single optfile for MPI and non-MPI built: merge few +mpi optfile
985        into previously non MPI one (linux_am64 pgf77,open64,pathf90,ifort11)
986      - linux_amd64_gfortran: merge +mpi_generic version into standard optfile:
987        * move IEEE flags to DEVEL section; take IEEE flags from +mpi_generic ;
988        * FAST case: for now, keep -O3 with ini_masks_etc.F in NOOPTFILES list;
989        and use "-devel" testreport option for standard testing on baudelaire.
990    o pkg/grdchk:
991      - Assume that all gradient-check position are within the same tile
992        corresponding to global indices (iGloTile,jGloTile) and that
993        positions (i,j indices or nbeg) are local to this tile;
994      - set tile local-indices and proc. number according to tile global-indices;
995      - remove grdchkwhichproc from namelist (retired param);
996      - send adjoint gradient to all procs so that all procs print it to STDOUT;
997      - switch on MPI test for global_ocean.90x40x15 AD test experiment.
998    o adding package bbl (Bottom Boundary Layer)
999      description in MITgcm/pkg/bbl/bbl_description.tex
1000      example/test experiment in MITgcm_contrib/bbl
1001    o adjoint verifications
1002      - changed 5 experiments to multi-tiles
1003        * global_ocean.90x40x15
1004        * obcs_ctrl
1005        * offline_exf_seaice
1006        * tutorial_dic_adjoffline
1007        * tutorial_tracer_adjsens
1008        changed reference output for those that crossed tile boundaries
1009        (changed choices of gradient check positions)
1010      - with same tiling, switch on MPI test for the last 4 (add SIZE.h_mpi)
1011      - temporary bug fix in grdchk_loc.F for obcs
1012    o genmake2 & testreport
1013      - add target "obj" (just for OBJFILES files) to Makefile;
1014      - add option to specify FEXTRAFLAGS on command line.
1015    o pkg/mypackage:
1016      - remove bi,bj arguments from argument list of S/R MYPACKAGE_CALC_RHS
1017    
1018    checkpoint63a (2011/08/02)
1019    o pkg/diagnostics (velocity potential):
1020      - fix velocity-potential calculation when using OBCS: balance net inflow
1021        at each level (new S/R OBCS_DIAG_BALANCE).
1022      - fix some of the problems with OBCS in stream-function calculation.
1023    o pkg/exf/exf_readparms.F
1024      - make treatment of optional namelists (EXF_NML_04, EXF_NML_SGRUNOFF,
1025        EXF_NML_OBCS) more consistent, so that you need not have these lists
1026        in data.exf when they are not used.
1027    o optim/optim_readdata.F:
1028      - add some output about obcs variables that might help debugging
1029      - add a check about nvarlength
1030    o pkg/ctrl: once again, fix computation of endrec in s/r ctrl_init_rec
1031    o pkg/diagnostics (velocity potential):
1032      - fix mask for OBCS (still problems in stream-function with OBCS);
1033      - add specific parameter (default = main code CG2D params) for solver;
1034      - in case of poor convergence, use solution corresponding to lowest residual.
1035    o pkg/seaice/seaice_growth.F: small changes that permit vectorizable
1036      adjoint code. In general statements like tmpscal=fld(i,j) are problematic
1037      and should be avoided where possible.
1038    o model/src (rStar):
1039      - include r* effect on reference-state (PhiRef) in totPhiHyd
1040        (so that it's really the potential anomaly at the cell center);
1041        affect solution only if z* with full pressure in EOS.
1042      - test-exp global_ocean.90x40x15: reduce viscA4 (was not stable) and
1043        update output (because of z* in totPhiHyd and viscA4 changes);
1044      - keep the previous diagnostics as "PHIHYDcR" (closer to potential anomaly
1045        @ constant r) until interpolation at constant r is implemented.
1046    o pkg/diagnostics
1047      - fix RCENTER diagnostics in case cell center is not at interface middle
1048    o add code for TEOS-10 (www.teos-10.org, McDougall et al. 2011). Use
1049      this eos with eosType = 'TEOS10', in data (PARM01). This eos implies
1050      that THETA and SALT are "conservative temperature" and "absolute
1051      salinity"
1052    o pkg/ctrl
1053      - fix computation of endrec in s/r ctrl_init_rec
1054      - ctrl_pack/unpack_*: remove unused variables and some obsolete code
1055    o pkg/seaice/seaice_growth.F
1056      - fix recomputation with FENTY_AREA_EXPANSION_CONTRACTION code,
1057        remove then obsolete STORE directives
1058      - fix STORE directives for tice and tices, so that only the
1059        appropriate part of the fields are stored (and not the entire
1060        field); update global_ocean.cs32x15.seaice AD output.
1061      - cosmetic changes: adjust CPP flags and indentation for better
1062        legibilty
1063    o pkg/autodiff: add mnc-output of adBottomDragFld (code contributed by
1064      Chris Wilson)
1065    o pkg/gmredi:
1066       Add Sub-Meso Eddies parameterisation from Baylor (for now, disabled with TAF),
1067       and test it in verification exp. "front_relax.bvp" (update output.bvp.txt)
1068    
1069    checkpoint63  (2011/07/11)
1070    o pkg/exch2:
1071     - rename+move: nTiles in W2_EXCH2_PARAMS.h --> exch2_nTiles in W2_EXCH2_TOPOLOGY.h
1072     - exch2 version of Cumul-Sum routine: S/R W2_SET_MAP_CUMSUM set up the
1073       (2*nTiles)x(nTiles) Cumul-Sum matrix and Master Proc collects all tiles X,Y
1074       increments, calculates Cumul-Sum @ tile origin and sends results to each tile.
1075    o pkg/diagnostics:
1076     - deal with pairs of post-processed diags which are computed together; in
1077       particular, re-order list of diags within 1 file to save 2nd computation.
1078     - add S/R to compute velocity stream-function (called after velocity-potential
1079       calculation) from divergence free transport -> new diagnostics "PsiVEL".
1080     - add parameter to select grid-point location where PsiVEL == 0.
1081    o eesupp/src:
1082       new S/R to calculate cumulated sum on tiled array, corner grid-cell location
1083       (specific S/R needed with exch2 topology - for now, just print an error msg)
1084    o pkg/shelfice
1085     - Implement friction velocity-dependent transfer coefficients following
1086       Holland and Jenkins, JPO, 1999
1087       Original code by M. Losch with small modifs.
1088       Enable with CPP option SHI_ALLOW_GAMMAFRICT
1089       and runtime flag SHELFICEuseGammaFrict
1090    o verification lab_sea & global_ocean.cs32x15:
1091     - use tools/xmakedepend (instead of cyrus_makedepend, in genmake_local):
1092       does not miss some dependencies (but is slower) and also works with many files
1093       (default makedepend limitation for AD built).
1094     - use cyrus_makedepend in adjustment.128x64x1 (so that it still tested).
1095    o pkg/diagnostics:
1096     - add run-time parameter "useMissingValue" (def=False) to fill land-point
1097        (i.e., where mask=0) with MissingValue ; used only in MNC output file.
1098       This replaces CPP-option DIAGNOSTICS_MISSING_VALUE.
1099     - Extend the use of "missing_value" setting from data.diagnostics for the case
1100       of counter-diagnostics (where fraction-weight is zero). This applies both to
1101       MNC and MDS output files.
1102    o pkg/seaice/seaice_growth.F:
1103      - add 'a priori' cap of latent heat flux based on actual mass considerations
1104        when SEAICE_ADD_SUBLIMATION_TO_FWBUDGET is used in conjunction with the
1105        non-legacy seaice_solve4temp.
1106      - add diagnostic of the residual sublimation freshwater flux (the freshwater
1107        flux taken from the ocean if the total actual latent heat fluxes exceed
1108        the maximum)
1109      - remove the CPP switch around the *_FWbySublim unit change and move diagnostic
1110       fill for SIatmQnt, SIfwSubl, SIatmFW to the end of seaice_growth.F.
1111      - add diagnostic of the actual sublimation freshwater flux (that is 0. ifndef
1112       SEAICE_ADD_SUBLIMATION_TO_FWBUDGET) and of the latent heat flux (evap+sublim).
1113      - bug fix : frWtrAtm needs a_FWbySublim ifdef SEAICE_ADD_SUBLIMATION_TO_FWBUDGET.
1114      - bug fix : missing part to Martin's r_FWbySublim pathological case fix.
1115    o verification 1D_ocean_ice_column:
1116       made model domain truly 1x1x23 instead of 5x5x23 with only center cell (3,3,:) wet
1117       update results
1118    o pkg/diagnostics:
1119     - Implement setting of "Post-Processed" diagnostics (corresponding to gdiag(5)='P')
1120       which are not filled-up but computed from other diags ; In this case, the mate
1121       diag points to the primary (filled-up) diag to used for post processing.
1122     - Update Velocity-potential computation using post-processed diag framework.
1123     ==> Change the ordering of fields and time-periods in MDS output file
1124       when using periodic averaging: now writes one time record with the full set
1125       of fields for this time period, then the next time reccord (it used to be
1126       one field with the full set of time records then the next field).
1127         Note: this is now similar to NetCDF (MNC) output file. <==
1128    
1129    checkpoint62z (2011/06/21)
1130    o adjoint monitor:
1131     - Add adjoint monitor output for packages exf, seaice
1132       and update relevant testreport output
1133    o pkg/seaice:
1134     - re-order diags inits so that they appear in order in available_diagnostics.log
1135     - added diags: hsnow thermo. rates of change, area preceeding ridiging process,
1136       area/heff/hsnow preceeding thermodynamic growth/melt.
1137     - modified diag: SIdA; output actual effect, as the description states.
1138     - modified description: SIqneti, SIqneto, SIuheff, SIvheff, SIdAb*, HSNOW.
1139     - retired redundant diags: SIyneg, SIfice, SIsnwice, SIthdgrh.
1140       (SIyneg->SIdHbOCN; SIfice->SIdHbATC; SIsnwice->SIdHbFLO;
1141        and SIthdgrh->SIdHbOCN+SIdHbATC+SIdHbATO)
1142     - modified diags (2) : switch all SIdA*, SIdH*, SIdS* from delta to rates.
1143     - added diagnostics for seaice generic tracers (SItr*).
1144     - added SItrUnit and SItrNameLong run time param (for SItr* diags).
1145     - in diag names, replaced 'PrTh' abbrev. of 'preceeding thermo' with 'PT'.
1146     I. Fenty: 18-Jun-2011:
1147     Minor changes to seaice package:
1148     1) Retired old variables (A22, SEAICE_lhsublim, areaMax, areaMin, hiceMin) and
1149        added some new ones (SEAICE_area_reg, SEAICE_hice_reg, SEAICE_area_floor)
1150       - Differentiated "regularization variables" from "floor variables"
1151        * areaMin became SEAICE_area_reg (old A22) and SEAICE_area_floor
1152        * hiceMin became SEAICE_hice_reg (old hiceMin)
1153          (with _reg meaning regularization variable)
1154       - SEAICE_lhSublim becomes lhSublim, the sum of SEAICE_lhEvap and SEAICE_lhFusion
1155        so as to ensure energy conservation when going between phases
1156      - A22 was not used anywhere
1157     2) Changed regularization procedure for heffActual and hsnowActual to ensure
1158        well-boundedness and smooth adjoint in seaice_growth.F
1159     3) Fixed a bug where seaice_solve4temp would not recognize ice-free grid cells
1160        because the old regularization always set heffActual >= 0.05 cm
1161     4) Changed the model so that the default behavior is to put a small (10^-5) "floor"
1162        on AREA when HEFF > 0.
1163      - went from requiring ALLOW_PRECLUDE_INFINITESIMAL_AREA to be defined to
1164        requiring that DISABLE_AREA_FLOOR *not* be defined
1165     Affected verifications:
1166      - 1D_ocean_ice_column (output.txt output_adm.txt)
1167      - global_ocean.cs32x15 (output.seaice.txt output_adm.seaice.txt)
1168    o pkg/diagnostics:
1169      - move MNC code from diagnostics_out.F into new diagnostics_mnc_out.F (2 S/R).
1170      - rename S/R GETDIAG to DIAGNOSTICS_GET_DIAG and change type of 1rst argument
1171        (was _RL, now integer) with option = 0 to retrieve all levels.
1172      - add pieces of code to compute velocity potential at each level (new diagnostics
1173        PhiVEL, works only when UVELMASS & VVELMASS are also turned on);
1174        for now, using same params as CG2D (target-resisual, max Nb of iter ...).
1175      - fix few issues with counter diagnostics in diagnostics_setdiag.F &
1176        diagstats_setdiag.F (if diagnostic counter is itself a counter diag)
1177        and in diagnostics_fract_fill.F (do not need a valid pointer for the
1178        diagnostics counter-mate); check that definition of counter-diagnostic
1179        includes a valid counter-mate (in diagnostics_set_levels.F).
1180    o model/src (rStar):
1181      - add rStar scaling factor in diags_phi_hyd.F (similar to calc_grad_phi_hyd.F);
1182        affect solution only if z* with full pressure in EOS;
1183        update output of test-exp global_ocean.90x40x15.
1184    o pkg/seaice:
1185      - introduce siEps=1e-5 parameter
1186      - use areaMax in AREA update (part 4), consistent with ridging step (part 2.5).
1187      - re-organize SEAICE_ADD_SUBLIMATION_TO_FWBUDGET code.
1188      - introduce ALLOW_SITRACER and seaice_tracer_phys.F to handle generic seaice tracer.
1189        For now it covers, and was tested for, ice salinity and age (attached to HEFF),
1190        as well as ice cover age and ridging index (attached to AREA).
1191        For now the run time parameters (in data.seaice/SEAICE_PARM03) are
1192        SItrName (e.g. 'age') and SItrMate ('HEFF', which is the default, or 'AREA').
1193        Up to SItrMaxNum=3 tracers can be used simultaneously.
1194    o pkg/salt_plume:
1195      -introduce SPsalFRAC run time parameter that sets the fraction of the
1196       salt by-product of ice growth (SPsalFRAC*(1-SIsalFRAC)*salt typically)
1197       that gets vertically redistributed (fluxed down) by pkg/salt_plume.
1198    o model debug options:
1199      - Switch reading of debugMode from S/R INI_PARMS (parameter file "data", stored
1200        in PARAMS.h) to S/R EESET_PARMS (parameter file "eedata", stored in EEPARAMS.h).
1201      - Refine debug-msg printing selection (3 new levels):
1202        debugMode  : controls printing of debug messages (sequence of S/R calls).
1203        debugLevel : controls printing of algorithm-relevant auxiliary/debug messages
1204         debLevZero =  0 ; /* level of disabled aux. msg printing */
1205         debLevA =  1 ; /* level of minimum  aux. msg printing */
1206         debLevB =  2 ; /* level of low aux. print (report read-file opening)*/
1207         debLevC =  3 ; /* level of moderate debug prt (most pkgs debug msg) */
1208         debLevD =  4 ; /* level of enhanced debug prt (add DEBUG_STATS prt) */
1209         debLevE =  5 ; /* level of extensive debug printing */
1210        New debugLevel default: with default debugMode value (=F),
1211          = 2 (debLevB) or = 1 (debLevA) in case ALLOW_AUTODIFF is defined.;
1212          and if debugMode=T, default debugLevel = 4 (debLevD).
1213        Relation with previous settings:
1214         debLevB (=2) corresponds to former debLevA (=1)
1215         debLevD (=4) corresponds to former debLevB (=2)
1216        Note:
1217         a) if debugLevel=0, skip WRITE_GRID call when nIter0 > 0 (same as before);
1218         b) default debugLevel=1 is convenient in AD runs (avoid many file opening msgs);
1219            to recover previous default, set debugLevel=2 (e.g. AD-test hs94.1x64x5)
1220      - Add new parameter (printResidualFreq, read from PARM02 namelist) to print
1221        detailed CG solvers convergence; off (=0) by default, except if debugLevel=5.
1222    o pkg/obcs:
1223      - change OBCSfixTopo default from True to False (should not change the results);
1224        keep OBCSfixTopo=T in verification-exp. seaice_obcs.
1225    o pkg/thsice:
1226      - fix bug in thsice_calc_thickn.F (was introduced in version 1.18) in
1227        2nd layer seaice sublimation (unlikely to happen)
1228      - use Interior mask for OBCS in thsice_advection.F (similar to what is
1229        done in gad_advection & seaice_advection).
1230    o adjoint:
1231      bug fix spotted by Gael Forget:
1232      seaice_advection and thsice_advection still had
1233      legacy CPP options to avoid CS corner updates for adjoint
1234    o pkg/seaice:
1235      => Change some of the defaults (2011/05/29):
1236         - change SEAICEuseFluxForm default (from False to True)
1237         - change DIFF1 default (from 0.004 m/s to 0. m/s)
1238         And print warnings if DIFF1 is not set in data.seaice and centered
1239          avection scheme is used without any diffusion.
1240      also:
1241      - fix seaice_diffusion calls in default AdvScheme part of seaice_advdiff.F;
1242      - set SEAICEdiffKh[] default in the same way as SEAICEadvSch[]
1243      - stop if DIFF1<>0 with SEAICEadvScheme <> 2, if DIFF1<>0 with any
1244        other non-zero SEAICEdiffKh[] diffusivity, if SEAICEadvSalt=T with
1245        #undef SEAICE_VARIABLE_SALINITY, if SEAICEadvAge=T with #undef SEAICE_AGE.
1246      update results of test exp.:
1247         lab_sea: output.fd (switch to AdvScheme=33 with diffKh=20)
1248             output.hb87, output_adm.evp (SEAICEuseFluxForm=T and diffKh=200)
1249             output_adm.noseaicedyn (SEAICEuseFluxForm=T)
1250         offline_exf_seaice: output.seaicetd, output_adm (SEAICEuseFluxForm=T)
1251         seaice_obcs: output (SEAICEuseFluxForm=T)
1252      and prescribe old default for SEAICEuseFluxForm (=F) and DIFF1 (=0.004)
1253          for standard fwd & AD lab_sea tests (to keep the same output).
1254    o pkg/seaice/seaice_growth.F:
1255      - use Ian Fenty's capping formulas for actual ice
1256      thickness thoughout EVOLUTION branch.
1257      - put treatment pathological case #2) in CPP brackets
1258      (ALLOW_AVOID_INFINITESIMAL_AREA, undef by default).
1259      - update global_ocean.cs32x15 and 1D_ocean_ice_colum results accordingly.
1260    o pkg/seaice:
1261      - seaice_diffusion.F : remove the min(DX,DY) factor permanently;
1262      pass the Laplacian diffusivity (in m^2/s) diffKh as a parameter;
1263      also pass fac as a param, which can be 1. (to update the tendency
1264      field) or the time step (to update the field itself).
1265      - seaice_advdiff.F: for multidim, call seaice_diffusion with
1266      e.g. SEAICEdiffKhHeff and with fac=1; for single-dim, call
1267      seaice_diffusion with e.g. SEAICEdiffKhHeff and with fac=time step.
1268      - SEAICE_PARAMS.h, seaice_readparms.F, seaice_check.F :
1269      hooks to handle SEAICEdiffKhHeff, SEAICEdiffKhArea, etc.
1270    o pkg/seaice:
1271      diffusion with centered advection scheme (diffus.F & advect.F):
1272      - simplify S/R DIFFUS (put deltaT & DIFF1 factor outside, move EXCH outside)
1273        to just compute the laplacian of input-field.
1274      - unroll k loop (harmonic,biharmonic diff) in advect.F to save 1 exch call.
1275      - fix flux-form version in diffus.F to conserve tracer.
1276      update output of lab_sea.fd & lab_sea.hb87 (1rst set of modif affects
1277       machine truncation) and lab_sea.salt_plume (conservative flux-form modif)
1278    
1279    checkpoint62y (2011/05/26)
1280    o pkg/seaice:
1281     - seaice_growth.F : in EVOLUTION branch, always include
1282       a_QSWbyATM_cover in qnet (as it should be).
1283     - verification/global_ocean.cs32x15 : update results accordingly
1284       (output.seaice.txt output_adm.seaice.txt).
1285    o pkg/seaice + obcs:
1286     - use maskInW & maskInS in multi-dim advection and biharmonic diffusion:
1287       equivalent of assuming no tracer gradient outside the OB region.
1288       update output of seaice_obcs (uses DIFF1 <>0 => biharmonic diffusion)
1289     - remove calls to OBCS_COPY_TRACER after EXCH calls (no longer needed
1290       after changes above);
1291     - obcs+seaice cleaning: apply seaice-tracer OB values to tracer field
1292       only at OB location (instead of over a band of OLx width).
1293    o pkg/seaice:
1294     - fix wrong indices in old (non Flux-Form) diffusion default S/R diffus.F
1295       (dxG(I+1, ...) changed to dxG(I, ...), no impact on Lat-Lon grid)
1296    o pkg/obcs:
1297      - split header file "OBCS.h" into 4 separated files:
1298        OBCS_PARAMS.h, OBCS_GRID.h, OBCS_FIELDS.h & OBCS_SEAICE.h
1299       Note: OBCS_PARAMS.h & OBCS_GRID.h can be included without OBCS_OPTIONS.h
1300         (contain no conditional statement which depends on OBCS options).
1301      - move "useOBCSYearlyFields" from "data.obcs" (hold in OBCS_PARAMS.h)
1302        to parameter file "data.exf", namelist EXF_NML_OBCS (in EXF_PARAM.h).
1303    o ctrl, cost, grdchk & autodiff pkgs:
1304      - make options file more standard (like other {PKG}_OPTIONS.h file but
1305        with AD_CONFIG.h); clean-up some of the included header files.
1306    o pkg/obcs:
1307      - do not mask tracer when applying OB (tracer == 0 could generate problems)
1308      - apply tracer OB values to tracer field only at OB location (instead of
1309        over a band of OLx width)
1310      - clean-up obcs_apply_w.F & obcs_apply_eta.F (since less calls to these S/R)
1311      - remove OBCS_MULTIDIM_OLD_VERSION code in gad_advection.F and remove
1312        obcs_apply_tloc.F & obcs_apply_sloc.F
1313    o obcs in model/src:
1314      - call OBCS_APPLY_W only if NonHydrostatic.
1315      - call OBCS_APPLY_ETA only if NonLinFreeSurf.
1316      - reset dEtaHdt and wVel to zero outside OB interior region ;
1317      - leave tracer unchanged outside OB interior region: This has no effect
1318        on the solution but just to prevent unrealistic tracer value outside OB.
1319      - zero out velocity outside OB interior region: This has no effect on
1320        the solution but just to prevent unrealistic velocity outside OB.
1321    o obcs and non-lin free-surf:
1322       move call to OBCS_APPLY_R_STAR from update_r_star.F to calc_r_star.F
1323       and call to OBCS_APPLY_SURF_DR from update_surf_dr.F to calc_surf_dr.F
1324       + add argument "etaFld" to OBCS_APPLY_R_STAR & OBCS_APPLY_SURF_DR:
1325       this fixes missing EXCH + get consistent eta OB value (+ fix restart).
1326       update results of test-exp. exp4(nlfs).
1327    o exp4 (nlfs) test-exp:
1328       use OBC for Eta at Western & Eastern OB (to test prescribing Eta
1329       with NonLin-FreeSurf); update output.nlfs.txt
1330    o obcs and 2d/3d solver norm:
1331       use interior masks (maskInC) to cancel out cg2d & cg3d matrix coeff at OB
1332       and outside OB interior region (will allow to place OB further inside the
1333       domain). Depending on the domain, can affects cg2d-Norm (previous
1334       cancellation outside OB was only partial), e.g. in exp4 & obcs_ctrl,
1335       and cg3d-Norm (previous Norm was computed before canceling OB terms),
1336       e.g. in tutorial_plume_on_slope.
1337      - update output of exp.: exp4 (x2), obcs_ctrl and tutorial_plume_on_slope.
1338    o pkg rbcs:
1339      - split RBCS.h into 3 files: RBCS_SIZE.h, RBCS_PARAMS.h & RBCS_FIELDS.h
1340      - add capability to apply relaxation to horizontal velocity uVel & vVel.
1341    o pkg/grdchk: add gradient check for control variable xx_shifwflx
1342    o pkg/shelfice/shelfice_init_fixed.F
1343      fix CPP-flag combinations
1344    o pkg/seaice: Merge iceage code of Pierre Rampal
1345      * update/change/correct ice age calculations
1346      * add age updates for pathological cases
1347      Probably needs more testing...
1348    
1349    checkpoint62x (2011/05/13)
1350    o pkg/mom_vecinv:
1351       high-order vorticity scheme: use interior masks (maskInW & S)
1352       to zero-out (outside OB) gradient of vorticity.
1353    o verification exp.:
1354       turn on "useEnergyConservingCoriolis" (better discretisation) in exp.
1355       hs94.128x64x5 and seaice_obcs ; update results.
1356    o pkg/obcs:
1357      fix bug in OBeta for YZ sections in obcs_exf_load.F
1358    o pkg/ctrl, pkg/shelfice, and optim:
1359      - add new control variable xx_shifwflx (fresh water flux underneath ice
1360        shelves). This is almost as tedious as obcs-ctrl, because the
1361        variables needs its own mask.
1362      - add a cost function term that penalizes the deviation of xx_shifwflx
1363        from the first guess (zero) in analogy to other control variables
1364    o pkg/shelfice:
1365      - start basic adjoint
1366    o pkg/ctrl:
1367      - remove extra 2D field "for good measure" when initializing in
1368        ctrl_set_globfld_[xy/xz/yz].F
1369      - replace hard coded precision 32 (a bug) in ctrl_map_ini_gen by ctrlprec
1370      - improve error messages in ctrl_set_unpack_*
1371    o OBC implementation in momentum:
1372       use interior masks (maskInC,W & S) in momentum S/R:
1373       - multiply divergence, tension and some del^i.u or del^j.v by maskInC
1374       - multiply del2u,del2v by maskInW/S (biharmonic viscosity)
1375       - multiply horiz. grad of vorticity by maskInW/S (in Leith scheme)
1376       - multiply gradient of wVel by maskInW/S in del2w calculation (NonHyd)
1377       Motivation: fix/clean implementation of OBC with biharmonic-viscosity
1378        (and also with Leith/Smagorinsky harmonic-viscosity).
1379       Update output of experiment dome and exp4 (+nlfs).
1380    o exp4 test-exp:
1381      - turn on: nonHydrostatic, exactConserv, viscA4 (with momDissip_In_AB=F)
1382        and prescribe time-varying OB (without pkg/exf) for zonal-velocity
1383        at Western & Eastern Boundaries (+/- 1 per-cent); Also prescribe
1384        time-varying OB at Western-side for wVel (NonHyd); update output.
1385      - add secondary set-up (.nlfs) using NonLin FreeSurf (z*) + mom_vecinv
1386        and biharmonic-viscosity ; also use prescribed time varying OB.
1387    o pkg/obcs:
1388      fix bug in OBWeta,OBWeta indices in obcs_apply_r_star.F
1389    o model/src:
1390      - fix startTime setting when baseTime<>0 & nIter0=0 are specified ;
1391      - initialise startTime & nIter0 with unlikely values: allows to set one
1392        from the other without ambiguity.
1393    o seaice_obcs test-exp.:
1394      add small diffK4T,S to test biharmonic diffusivity with OBCS ; update output.
1395    o pkg/obcs:
1396      - remove calls to OBCS_COPY_TRACER after EXCH for T,S & pTracer:
1397        no longer needed with maskInC,W,S in pkg/generic_advdiff.
1398    o pkg/seaice:
1399      - retired SEAICE_SALINITY and SEAICE_salinity in favor of
1400        SEAICE_VARIABLE_SALINITY and SIsalFRAC, respectively.
1401      - fixed bug in the initialization of sea ice salinity variable HSALT
1402        in seaice_init_varia.F  (removed dependence on ICE2WATR)
1403    o fizhi-cs test exp.:
1404       switch reference output convention for these 2 non-standard test-exp,
1405        from: pgi  6.1-5 on faulks (FC.6, -of linux_ia32_pgf77+authors_fc5)
1406          to: ifort 11.1 on baudelaire (FC.13, -of linux_amd64_ifort11)
1407       reason: faulks might get retired soon and pkg/fizhi has still Pb with gfortran
1408    o model/inc:
1409      - change type of PmEpR array (from _RS to _RL) to fix restart (with "-use_r4")
1410        of exp. global_ocean.90x40x15 (Suncronous time-stepping + Real-FW + NonLin-FS)
1411    o pkg/seaice:
1412      - fix calculation of saltFlux and saltPlumeFlux when using SEAICE_SALINITY
1413    o verification/lab_sea, 1D_ocean_ice_column, seaice_obcs, global_ocean.cs32x15
1414      - updated output*.txt files due to bug fixes in salt, saltPlumeFlux,
1415        and initial HSALT
1416    
1417    checkpoint62w (2011/04/26)
1418    o pkg/mom_fluxform:
1419      - fix calculation of del2u & del2v (no-slip BC) when using Non-Lin Free-Surf.
1420      - use parameter "sideDragFactor" in no-slip BC side-drag part.
1421      - update output of exp. global_ocean.90x40x15
1422    o pkg/mom_vecinv:
1423      mask del2u & del2v (no effect on results, but cleaner & closer to mom_fluxform)
1424    o update seaice exp.:
1425      use more consistent parameter values (remove "backward compatability only":
1426       ICE2WATR, SEAICE_lhSublim, SEAICE_cpAir, SEAICE_rhoAir + set rhoConstFresh)
1427      related to thermodynamics seaice. Update output (fwd+AD) of exp.:
1428       1D_ocean_ice_column (x2), lab_sea (x8), ioffline_exf_seaice (x2) & seaice_obcs
1429    o update test-exp global_ocean.90x40x15:
1430      o use default CD_CODE_OPTIONS file (Adams-Bashforth on CD Mom & Coriolis).
1431      o increase Overlap size from 2 to 3 (to allow to test bi-harmonic Visc.)
1432      o new pickup-files from a 100.yr run with pkg/down_slope (input.dwnslp params)
1433      o turn on zStar & viscA4 in standard set-up (dir input/)
1434        and update output files: output.txt & output.dwnslp.txt
1435    o new AD-test experiment: obcs_ctrl
1436      (From Matt MITgcm_Contrib/SOSE/BoxAdj) to test OBCS as control vector.
1437    o pkg/dic:
1438      fix two bugs in handling water vapour pressure in carbonate chemistry
1439      and air-sea fluxes. Found by Val Bennington and Galen McKinley
1440      (add DIC Option = WATERVAP_BUG to recover old results)
1441      update output of tutorial_global_oce_biogeo (fwd+AD) & tutorial_dic_adjoffline
1442    o adding allowInteriorFreezing option to check for water below freezing point
1443      at depth and bring the negative heat anomaly to the surface level
1444    o pkgs _fields_load:
1445      - extend GET_PERIODIC_INTERVAL to deal with non-periodic case (from pkg/rbcs)
1446      - use new S/R GET_PERIODIC_INTERVAL in pkgs:
1447        bulk_force, cheapaml, cfc, dic, obcs (+ ctrl/ctrl_get_gen_rec), offline and
1448        rbcs to get interpolation weights and time reccord number.
1449      - fix multi-threading in aim_fields_load.F
1450      - apply EXCH to temp arrays [0,1] after reading in dic_fields_load.F
1451    o external_fields_load:
1452      new S/R GET_PERIODIC_INTERVAL to calculate which time-record (and linear
1453       interpolation weights) to use in a periodic time-series ; do not divide by
1454       time-step to convert to integer:
1455       - this fixes case where externForcingPeriod is not multiple of time-step
1456          (Thanks to Christopher L. Wolfe)
1457       - this fixes case where externForcingPeriod is an odd multiple of time-step
1458         (was wrong by half of time-step); update results of tutorial_global_oce_in_p.
1459      store index of time-record which is currently loaded:
1460       - works without any assumption on sequence of calls to EXTERNAL_FIELDS_LOAD ;
1461       - needed for the adjoint but not yet used because of extensive recomputations;
1462         (to be fixed soon)
1463    
1464    checkpoint62v (2011/04/02)
1465    o verification/1D_ocean_ice_column added to test Ian Fenty's
1466      pkg/seaice_growth.F modifications for improving sea ice code differentiability
1467    o update output of exp4, internal_wave, seaice_obcs, tutorial_plume_on_slope
1468      (new velocity statistics after changing maskInW & maskInS definition)
1469    o pkg/generic_advdiff with OBCS:
1470      use maksInW & maskInS in advective flux and in biharmonic diffusion calculation:
1471      equivalent to assumption of no tracer gradient outside the OB region.
1472      This will affect the results if using obcs+biharmonic diffusion.
1473      update output_adm.txt of experiment bottom_ctrl_5x5 (not expected since no obc)
1474    o pkg/obcs:
1475      change definition of maskInW & maskInS: leave OB edges inside (maskIn=1)
1476      (e.g., maskInW(OB_Ie)=1 ) so that velocity normal-component at OB is still
1477      in Interior region. No impact on solution but affects Velocity monitor stats.
1478    o pkg/ptracers (adjoint)
1479      New option AUTODIFF_PTRACERS_SPLIT_FILES for writing separate
1480      tape file for each tracer
1481    o model/inc/src and pkg/autodiff: add parameters that allow to turn
1482      of parts of the adjoint code at run time. For now, there are only
1483      useKPPinAdMode, useGMrediInAdMode, and useSEAICEinAdMode. These
1484      parameters are set in data.pkg.
1485      This is the lazy coward's version of doing this, but still useful for
1486      debugging. In order to do it right, everything needs to be moved to
1487      pkg/autodiff.
1488    o pkg/autodiff: fix global_sum_tile_ad.F by resetting adsumPhi at
1489      the end; this fixes the adjoint balancing code for open boundaries.
1490    o pkg/ctrl:
1491      - change behavior of xx_${varname}period to be analogous to exf-conventions:
1492        xx_${varname}period =   0.,  means time-independent control part
1493        xx_${varname}period = -12., means one-year-periodic monthly control part
1494      - introduce helper routine ctrl_init_rec (part of ctrl_init.F) to
1495        clean up ctrl_init a little, remove unused variables
1496      - ctrl_init: fixed the handling of the start/endrec for obcs-variables
1497      - move "call cal_GetMonthsRec" from s/r ctrl_get_gen to s/r ctrl_get_gen_rec
1498    
1499    checkpoint62u (2011/03/15)
1500    o model/src:
1501      - for the adjoint, change NonLin-FreeSurf initialisation sequence: fill-in
1502        h0Fac from INITIALISE_FIXED and reset hFac to h0Fac in INITIALISE_VARIA ;
1503      - in initialise_varia.F (except for ALLOW_DEPTH_CONTROL) remove 2nd call to
1504        INI_DEPTHS, INI_MASKS_ETC & INI_LINEAR_PHISURF.
1505    o pkg/ctrl/obcs/ecco:
1506      - remove obsolete, unused, and partially broken code:
1507        ctrl_obcsvol/ctrl_obcsbal/ctrl_volflux and code within
1508        ALLOW_CTRL_OBCS_BALANCE
1509      - put a stop statement into ecco/cost_obcsvol.F, but also add
1510        cost_obcsvol to ecco_ad_diff.list
1511    o pkg/ecco: fix counting cost function contributions for obcs (code
1512      by Matt M.) and diffkr for diagnostics
1513    o pkg/ecco, pkg/ctrl, pkg/grdchk:
1514      add cost penalty terms for initial uvel, vvel, eta controls
1515      and I/O for prior error files
1516    o pkg/mdsio:
1517       move mds_check4file.F from eesupp/src to mdsio_check4file.F ; add option
1518       (new argument) to check for tiled file in mdsioLocalDir : this fix the
1519       restart from pickup_som , pickup_dic (& dic_co2atm) with mdsioLocalDir.
1520    o pkg/ctrl:
1521     - ctrl_obcsbal.F, ctrl_obcsvol.F: replace last calls of ctrl_getrec by
1522       ctrl_get_gen_rec, put a stop statement into ctrl_getrec. Remove
1523       unused and superfluous variables
1524     - ctrl_get_gen_rec.F: catch the case of xx_genperiod=0.
1525    o pkg/ecco
1526     - enable adjoint of Stevens OB
1527    o pkg/ctrl/ecco/grdchk:
1528      - remove global declaration of tmpfldx/yz and tmpfldx/yz2.
1529        Fortunately, we do not have any tests for the numerous cpp-flagged
1530        option of "obcs as control parameters" so we will never know
1531        if this is an improvement (but at least now things compile).
1532      - remove an obsolete initialization from ecco_cost_init_barfiles.F
1533      - fix some problems within never used ifdefs to make the code compile
1534    o pkg/obcs:
1535     - Refine Interior mask definition to work with more complex OB (e.g.
1536       if OB_Ie < OB_Iw); In case default setting is not sufficient, allows to
1537       read in Interior mask from file. Check if Interior mask is consistent
1538       with OB list of indices.
1539    o pkg/seaice
1540     - beginning code for a seaice tracer package,
1541       but currently only used for seaice age: SEAICE_AGE
1542       SEAICE_num = 4
1543       iTracer = 1: area-weighted ice age
1544               = 2: volume-weighted ice age
1545               = 3, 4: template for one-year vs. multi-year ice
1546       data.seaice has new namelist SEAICE_PARM03 for arrays related to
1547       SEAICE_num
1548    
1549    checkpoint62t (2011/03/05)
1550    o pkg/obcs:
1551     - obcs_apply_uv.F: change to a 2 steps method, first tangential component;
1552       then normal component. This ensures that the normal component is set
1553       correctly even when it conficts with tangential setting from an other OB.
1554       Affects results of test-experiment seaice_obcs: update the output.txt
1555    o pkg/obcs:
1556     - add code to monitor statistics of dynamical fields at OB.
1557     - take OBCS_BALANCE code out of obcs_calc.F into new S/R OBCS_BALANCE_FLOW :
1558       - fix to OBCS_BALANCE code (right hFac ; deal with simple OB intersection).
1559       - change default: balance the Net inflow through all OB (instead of balancing
1560         each OB separately); keep the old method if setting OBC_balanceFacX < 0.
1561     - switch on useOBCSbalance in dome experiment: only correct Western OB outflow
1562       to match Nortern OB inflow (OBCS_balanceFacN=0).
1563    o pkg/seaice:
1564     - redefined actual sea ice age to be ICEAGE/HEFF ifdef SEAICE_AGE_VOL
1565    o pkg/seaice (seaice_growth v 1.113):
1566     - reverting seaice_growth to v 1.111 in order to have code with exact bit
1567       compatibility with MITgcm_contrib/ifenty/Fenty_seaice_thermo_code_merge
1568       CPP option SEAICE_OCN_MELT_ACT_ON_AREA removed in v 1.112 is reintroduced
1569       runtime flag SEAICEareaFormula is kept but is inactive
1570    o model/src:
1571     - add new param to scale curvilinear grid distance and area when using
1572       a different sphere radius from the grid-files.
1573     - test/check multi-threads EXCH applied to local variable (cg2d_x)
1574    o adjoint:
1575     - enable adjoint of Stevens OB
1576     - add dummy_in_dynamics to enable extraction of ADJrhoinsitu
1577       (a bit delicate because of potentially modified adj. common block structure;
1578       current switch is ALLOW_AUTODIFF_MONITOR_DIAG, could be changed later)
1579    
1580    checkpoint62s (2011/02/15)
1581    o pkg/seaice (seaice_growth v 1.112):
1582     - introduce SEAICEareaFormula run time parameter, which selects the recipe for
1583       computing the ice cover tendency from effective thickness tendencies. Include
1584       Ian Fenty's formula.
1585     - remove 'undef SEAICE_OCN_MELT_ACT_ON_AREA' which may now be achieved using
1586       SEAICEareaFormula.
1587     - simplify notations for the various d_HEFF/d_AREA terms.
1588    o pkg/gmredi:
1589     - add Boundary-Value-Problem bolus transport (Ferrari etal, OM 2010) code
1590       from Christopher Wolfe (UCSD); add partial cell factor in vertical derivative;
1591       add a verification test-run (front_relax.bvp) to test GM_useBVP.
1592    o pkg/seaice (seaice_growth v 1.111):
1593     - for SEAICE_DO_OPEN_WATER_GROWTH, replace Gael's implementation with Ian's.
1594     - the new SEAICE_DO_OPEN_WATER_MELT allows open-water air-sea heat fluxes to
1595       also melt ice.
1596    o pkg/seaice:
1597     - McPhee formula for Ice-Ocean fluxes (provided by Ian Fenty).
1598     - can be used by #define MCPHEE_OCEAN_ICE_HEAT_FLUX in SEAICE_OPTIONS.h
1599    o pkg/cheapaml:
1600     - from Nico Wienders: New version of this package.
1601    o pkg/flt:
1602     - add CPP options to prevent floats to re-enter the opposite side of
1603       a periodic domain (default: keep periodicity)
1604    o pkg/gmredi:
1605     - apply exchange to GM_PsiX,GM_PsiY to get valid values near CS-corners
1606       (needed for multi-dim advection).
1607     - switch on GM Advective form in global_ocean.cs32x15 and update output.txt
1608    o model/src:
1609     - fix wrong re-setting of addMass array (ALLOW_ADDFLUID) for atmospheric run.
1610    o tutorial_tracer_adjsens
1611     - extend to NLFS and replace maskC by hFacC
1612       (change reference output accordingly)
1613    
1614    checkpoint62r (2011/01/24)
1615    o testreport:
1616     - add option -deloutp (-do) to remove output file after successful run
1617     - add option -mfile (-mf) for MPI machile-file and for each test-exp,
1618       extract exact list of procs from this file ; adjust COMMAND by
1619       replacing TR_MFILE & TR_NPROC with local machile-file & Nb of MPI procs.
1620    o pkg/ecco: replace old ineffective way of penalizing deviations from
1621      first guess (of obcs) with code by Matt Mazloff
1622    o pkg/ctrl: add code that allows the use of ALLOW_OBCS?_CONTROL without
1623      exf/cal
1624      - ctrl_init: fix initialisation (computation of diffrec) for obcs-ctrl
1625        and handle case of obcs?period == 0
1626        Not affected by these changes: There is still an inconsistency in
1627        the computation of start/endrec for the obcs variables for ALLOW_CAL
1628        defined (see comment by Menemenlis, 7-Mar-2003)
1629      - make S/R ctrl_get_gen_rec return something meaningful even if
1630        ALLOW_CAL is not defined
1631      - ctrl_getobcs?: simplify code so that it does not need to use
1632                       S/R exf_swapfields
1633    o testreport:
1634       allow to test MPI with different number of processors for each experiment:
1635       create file "SIZE.h.mpi" in each build dir.
1636       Note: update of "-command" argument not yet implemented.
1637    o model/src, pkg/autodiff, pkg/ecco, pkg/seaice:
1638      alleviate the need for additional 3D tapes when using
1639      the non-inear free surface in the adjoint. This is done
1640      by adding an 'update' of hfacc etc. to their current
1641      value at the beginning of forward_step.F.
1642    o pkg/seaice
1643      seaice_lsr: move stress-divergence computations out of outer pseudo-
1644      timestepping loop
1645    o pkg/obcs/obcs_prescribe_read.F: move 'CALL OBCS_EXTERNAL_FIELDS_LOAD'
1646      up, so that the calls of the ctrl_* subroutines are really at the end
1647      of the routine.
1648    o pkg/gmredi:
1649      allow to specify a 2-D horizontal map and a 1-D vertical profil
1650      as scaling factor for Isopycnal diffusivity (Redi) and GM diffusivity.
1651    o pkg/seaice:
1652      move lsr iterations from seaice_dynsolver to seaice_lsr.
1653    o pkg/seaice:
1654      reduce memory footprint of seaice mutldim advection tapes,
1655      by using a 2D tape independent of the generic_advdiff ones,
1656      and setting GAD_AREA=1 etc. rather than GAD_AREA=101 etc.
1657    
1658    checkpoint62q (2010/12/29)
1659    o model/src:
1660      - check horizontal grid-spacing for unset or zero/negative values.
1661      - change AD test hs94.1x64x5 to be truly a 2-D set-up.
1662    o pkg/flt:
1663      - use (recent) mdsio S/R MDS_READVEC_LOC instead of local FLT_MDSREADVECTOR
1664      - precision of input and output files set according to readBinaryPrec
1665        and writeBinaryPrec (previously always 64.b), pickup remains at 64 bits.
1666      - initial float position from tiled file was not converted to index space
1667        (looks like a bug): fixed to make it similar to initial pos. global file.
1668    o global_ocean.cs32x15:
1669       change SIZE.h of AD set-up to get same tiling as with MPI.
1670       Update output_adm, output_adm.thsice (pass@14) & output_adm.seaice (fail@11)
1671    o model/src:
1672       add flag to control printing of domain fields (bathymetry, hFac ...) in
1673       ini_mask_etc (call to plot_fieds_xy*).
1674    o pkg/thsice:
1675       if useEXF, some forcing fields are not valid in overlap: fixed by computing
1676       over the interior only + apply EXCH at the end (like with SEAICE advection).
1677    o pkg/mdsio:
1678      - add 2 arguments to S/R MDS_PASS_R4/8toRL/S for overlap size of buffer
1679        to copy to/from, so that it can be used to replace MDS_PASS_WH_R8toRL/RS.
1680      - change barrier call for safe multi-threads access to 3-D shared buffer.
1681      - MDS_READ/WRITEVEC_LOC use buffers from MDSIO_BUFF_3D.h (instead of local ones)
1682      - replace call to MDS_PASS_WH_R4/8toRL with call to MDS_PASS_R4/8toRL and
1683        remove the 4 S/R MDS_PASS_WH_R4/8toRL/S.
1684    o pkg/flt:
1685      - add fourth-order Runge-Kutta integration
1686      - add basic exch2 support (only 1 facet supported so far!)
1687    o pkg/mdsio+rw:
1688      new S/R to read local (or tile independent) vector (read counterpart of
1689       mds_writevec_loc, and front-end write_glvec_rl/rs).
1690    o global_ocean.cs32x15: additional input_ad.seaice experiment
1691        that uses pkg/seaice rather than pkg/thsice.
1692        (using multidim advection for seaice)
1693    o towards more F95 syntax for array specification in namelist:
1694      - change "data.diagnostics" (data.ptracers was changed before checkpoint62p)
1695        of all verification experiments.
1696           e.g.:    line: fields(1,3)='ETAN    ','ETANSQ  ',
1697          was changed to: fields(1:2,3)='ETAN    ','ETANSQ  ',
1698      - finish adding "-DNML_EXTENDED_F77" to DEFINES list in pgf77 and g77 optfiles
1699    o global_ocean.cs32x15: additional input.seaice experiment
1700        that uses pkg/seaice rather than pkg/thsice.
1701    
1702    checkpoint62p (2010/12/17)
1703    o pkg/thsice: rename (ad tape index) iicekey as ticekey, and move it
1704        to THSICE_SIZE.h to avoid conflict with pkg/seaice.
1705    o pkg/seaice: add seaice_diffusion.f seaice_map_thsice.f to adjoint.
1706        allow for use of multim. advection in seaice adjoint.
1707    o pkg/seaice: add diagnostics for snow precipitation and sublimation flux
1708      - first attempt to close budgets by taking into account the freshwater
1709        flux implied by the sublimation of snow and ice. So far only the
1710        volume budget is closed, turn on with soon-to-be-retired-again CPP-Flag
1711        SEAICE_ADD_SUBLIMATION_TO_FWBUDGET
1712    o eesupp/src:
1713      new S/R with new option (NML_EXTENDED_F77) to change array specification
1714      from F95 standard to commonly accepted extended F77 form.
1715      This would allow to use F95 syntax in namelist (needed with gfortran 4.4.5)
1716      and to revert back to the original syntax (with -DNML_EXTENDED_F77)
1717      for less tolerant f77 compiler (e.g., pgf77, g77).
1718    o globalFiles:
1719      commented out in parameter file "data" since it's not safe with MPI
1720      (e.g., wrong on aces); keep it if useSingleCpuIO=T (but not doing much
1721      in this case); no longer commented out in restart test (tst_2+2).
1722    o add adTapeDir to specify a special directory where adjoint tapes are
1723      written/read (adread_adwrite.F). adTapeDir is specified in data/PARM05
1724      and cannot be used together with mdsioLocalDir.
1725    o nesting pkgs:
1726      - packages_init_variables : put call to OBCS_INIT_VARIABLES in last position
1727      - update Gianmaria's Nesting pkgs (from Contrib/nesting_sannino)
1728      - add parameter files + utils dir + output from short run on beagle.
1729    o pkg/seaice:
1730        fix seaice_growth.F store directives; update results of exp. lab_sea.ad
1731    o pkg/seaice: explicitly store tsurfloc in seaice_solve4temp.F to avoid
1732      unnecessary copying in adjoint code, requires new parameter NMAX_ITER
1733    
1734    checkpoint62o (2010/11/25)
1735    o pkg/exf:
1736      - change CPP option EXF_VERBOSE to run-time logical param exf_verbose.
1737    o pkg/seaice:
1738      - seaice_ocean_stress: split a loop for better vectorization of the
1739        adjoint code
1740      - seaice_growth.F: fix bug in conservation of freshwater connected to
1741        capping of heff, put contribution into d_HEFFbyNEG
1742      - replace irritating parameters SEAICE_latentWater/Ice and SEAICE_sensHeat
1743        by something more sensible (parameters that are what their name implies)
1744      - change some defaults, so that by default exf-parameters are used for
1745        things like rhoAir, cpAir,latent/sensible heat parameters, in order
1746        to reproduce the old results, many data.seaice now contain funny values
1747        for cpAir and latent heat of sublimation
1748    o packages_readparms.F: move exf_readparms up in line so that
1749        exf-parameters are visible for other packages (e.g. seaice)
1750    o debugMode & debugLevel=2:
1751      - differentiate between debugMode & debugLevel=2:
1752        debugMode: controls printing of debug messages (sequence of S/R calls).
1753        debugLevel: controls printing of algorithm intermediate results and stats.
1754      - remove "if debugLevel=2 => debugMode" but keep "debugMode =>  debugLevel=2";
1755        => allows to print debug-stats without all sequence of call messages.
1756      - switch control of debug print from debugLevel to debugMode in many S/R.
1757    o pkg/obcs (obcs-sponge):
1758        fix bug that was introduced on Oct 25 (in dynamics.F v1.151): put back the
1759        call to OBCS_PRESCRIBE_EXCHANGES (need to exch gU,gV when using obcs-sponge)
1760    o pkg/generic_advdiff:
1761      - record overlap minimum size for each advection scheme;
1762      - refine criteria on overlap minimum size;
1763      - check and stop (in gad_check) if overlap size is too small.
1764    o pkg/obcs:
1765      - with ptracers: remove multiple calls to obcs_apply_ptracer (only done
1766        once, in ptracers_implicit.F)
1767      - with seaice: remove test on empty file name in obcs_apply_seaice (always
1768        apply OB values when tile has OB)
1769    o model/src, coriolis setting:
1770      - integer parameter "selectCoriMap" (=0,1,2) replaces 3 logical
1771        useConstantF, useBetaPlaneF, useSphereF ; can now read coriolis from
1772        files (selectCoriMap=3) with any grid.
1773      - add parameter "fPrime" for constant second Coriolis coeff (default=0).
1774    o pkg/seaice/seaice_growth.F:
1775        a few cosmetic changes that reduce the number of lines of code
1776    o pkg/obcs: add boundary conditions following Stevens (1990)
1777      - the code follows old MOM/NAOSIM code
1778      - so far it is only implemented for the eastern and western boundaries
1779        and NOT for pTracers
1780    o pkg/rbcs:
1781      - replace rbcsInIter by rbcsForcingOffset, the time in seconds at the
1782        beginning of the first rbcs forcing period.
1783      - add option rbcsSingleTimeFiles that makes rbcs read forcing data like the
1784        offline package, i.e., one file per time, labeled by iteration number;
1785        deltaTrbcs sets the timestep with which the data was generated;
1786        rbcsIter0 is the forcing iteration corresponding to rbcsForcingOffset.
1787      - rbcsForcingCycle=0 makes forcing non-cyclic.
1788      - make arithmetic safe for negative times and odd forcing periods.
1789    
1790    checkpoint62n (2010/11/09)
1791    o pkg/seaice:
1792        fix masking in free-drift S/R ; update results of exp. lab_sea.fd
1793    o pkg/obcs:
1794       New S/R to copy tracer value from the OB location to narrow band region
1795        (width = same as overlap) beyond the OB: preserve OB value (needed for
1796        high-order scheme) which were overwritten by EXCH call if in overlap
1797        region. Applied to theta, salt, ptracer and advected seaice variables.
1798       With seaice: use maskInC in similar way as in gad_advection.F,
1799        in seaice_advection.F and advect.F.
1800       Update output of experiment seaice_obcs and change exp4 to test OBCS with
1801        4th order Adv.Scheme. for pasive salt and ptracer.
1802    o tools/genmake2:
1803      - when looking for an optfile (not specified), only search for Fortran compiler
1804        (remove sym-link test + setting of CPP + makedepend check + C-compiler check)
1805      - in get_fortran_c_namemangling: use "$CC $CFLAG" to compile C test programm
1806        (instead of "$MAKE genmake_test.o" since an existing Makefile can be wrong)
1807      - set default for CPP to "cpp -traditional -P" (was the case without specifying
1808        an optfile, but otherwise default was just "cpp".
1809      - comment out PLATFORM=$p_PLATFORM (no idea where p_PLATFORM comes from)
1810      - when "CC" is not set in the optfile, look for possible C compiler
1811        (instead of just setting CC=cc)
1812      - put back version v.169 modif (from 2008/02/15), was dropped in v.173 changes:
1813        => add a ".F" to ".o" rule for source files with no "#include" (such as
1814           port_rand.F); otherwise, default ignores FOPTIM and just uses FFLAGS.
1815      - move gfortran before g77 in list of possible Fortran compiler (consistent
1816        with reference compiler switch from g77 to gfortran)
1817    o pkg/seaice:
1818      o remove SEAICE_OLD_AND_BAD_DISCRETIZATION-code, add a test to
1819        seaice_check that stops the model, when the CPP flag is used.
1820      o seaice_growth.F: make capping of ice volume conserving by returning the
1821        capped ice as freshwater to EmPmR. This does not change the verification
1822        experiments but will change runs where the capping is acutally active
1823    o change reference platform+compiler from faulks+g77 to baudelaire+gfortran
1824      (except the 2 fizhi test exp.); update output of exp.: bottom_ctrl_5x5,
1825         global_ocean.cs32x15 (icedyn, thsice, AD thsice), global_ocean_ebm (AD),
1826         lab_sea (fd, hb87, salt_plume), MLAdjust (3/5) and vermix (dd)
1827    o tools/genmake2:
1828      - merge genmake_warnings & genmake_errors into 1 log file: "genmake.log")
1829      - change DUMPSTATE default to false (can use "-ds" option to switch it to T)
1830      - clean previous genmake log files before anything else.
1831      - change Makefile to remove testreport log files (*.tr_log) and genmake log
1832        files only with "CLEAN" target (instead of "Clean");
1833    o pkg/generic_advdiff:
1834      Change OBCS in multiDim advection (gad_advection.F):
1835       Use maskInC to prevent intermediate update of tracer-field in OB regions,
1836       thus keeping current-time-step OB values; and remove the call to OBCS_APPLY
1837       which were applying future time-step OB values.
1838      This way, all explicit calculations use current-time-step OB values
1839       (simpler and more consistent).
1840      Affects results when set-up uses time-varying OBC and multi-dim advection;
1841       update output of experiment seaice_obcs.
1842    o pkg/seaice:
1843      move OPTIONS (formerly locally defined) to SEAICE_OPTIONS.h:
1844       this includes SEAICE_GROWTH_LEGACY (+ SEAICE_DO_OPEN_WATER_GROWTH &
1845         SEAICE_OCN_MELT_ACT_ON_AREA ) and SEAICE_SOLVE4TEMP_LEGACY.
1846      Default (pkg/seaice/SEAICE_OPTIONS.h) is to define SEAICE_SOLVE4TEMP_LEGACY
1847       but leave SEAICE_GROWTH_LEGACY undef ; For now, keep verification exp
1848       unchanged (SEAICE_GROWTH_LEGACY defined in */code*/SEAICE_OPTIONS.h)
1849    o pkg aim (2010/10/26):
1850      - Introduce ALLOW_INSOLATION, moving toward a more general incoming solar radiation
1851        formulation with obliquity, eccentricity, ... as run-time parameters,
1852      - Introduce diagnostics for top-of-the-atmaophere incoming solar radiation and
1853        upward shortwave radition at the surface (all-sky and clear-sky).
1854    o pkg/obcs:
1855      - writing sections with globalFiles=T does not work: switch to tiled-files
1856        when writing sections for OBCS (change pkg/rw/write_rec.F accordingly).
1857      - fix index bug (OB_Ie -> OB_Iw_) in obcs_apply_uvice.F
1858      - apply OBCS_SEAICE_COMPUTE_UVICE to both uice and vice at all obcs
1859    
1860    checkpoint62m (2010/10/21)
1861    o pkg/seaice: vectorize seaice_solve4temp.F
1862      - move iterations loops outside of i/j-loops
1863      - requires 2D arrays for TB and effConduct
1864      - add 2D iceOrNot to replace HICE_ACTUAL.GT.0, as HICE_ACTUAL is
1865        modified in this routine
1866      - a little bit of clean up, adjusting indentation, etc.
1867      - replaced a few TEN**a by exp(a*log(10.)) in new code for better
1868        performance and '**TWO' by '**2' (because TWO is a float),
1869        replaced ONE, ZERO
1870    o eesupp/src:
1871       fix flow dir for exch1_z_RX_cube, exch1_uv_RX_cube & exch1_bg_RX_cube
1872    o pkg/seaice/seaice_growth.F
1873      Revision 1.89 of seaice_growth.F completes the overall october 2010 revision and
1874      merging process. The merged routine has two branches, and one activates the 'evolution'
1875      branch by setting SEAICE_GROWTH_LEGACY to undef (at the top of the routine for now).
1876      In summary, here is what the '10/10 revision' did consist of
1877        part 1: seaice_growth.F revisions 1.71 to 1.75
1878          - Preliminary seaice_growth.F clean-up, keeping test results strictly unchanged.
1879            The emphasis here was on improving readability (e.g. by trying to use meaningful
1880            variable names) and modularity (e.g. by adding arrays to store heff etc. updates).
1881        part 1.5:
1882          - revising the lab_sea experiment to make it a more useful (i.e. stable
1883            and representative of an actual model run). This was done by generating a
1884            (winter) pickup to start from, switching back the main experiment dynamic
1885            solver from evp to lsr, having one of the experiments use the free drift solution.
1886        part 2: seaice_growth.F revisions 1.76 to 1.85
1887          - Sorting out hard-coded constants that prevented heat and fresh water conservation.
1888          - Sorting out the various fields units and sign (set early on and reset at the end)
1889            to avoid numerous scalings/re-scalings. By v1.85 the basic unit for ice, heat and
1890            fresh water stock is 'effective ice meters', and >0 implies more ice/snow.
1891          - Using tendency terms arrays (d_HEFF* etc.) to alleviate remaining code locks,
1892            and simplifying logical expressions to further improve readibility.
1893        part 3: seaice_growth.F revisions 1.86 to 1.89
1894          - Re-organize the blocks of code more logically.
1895          - Merging the '_if.F' pieces that add something new.
1896    o pkg/thsice:
1897      - vectorize thsice_solve4temp and thsice_get_exf.
1898        Problem: thsice_solve4temp has an unvectorizable statement that
1899        might also be problematic for TAF
1900      - thsice_get_exf: add the ALLOW_BULK_LARGEYEAGER04 CPP-flag. This
1901        does not change the verifcation experiment, but will change all
1902        experiments that have this flag undefined (not tested in verification);
1903        a little reorganization to save a few 2D fields and recomputations
1904      - 1st step of revisiting thsice adjoint (major recomp. sorted out)
1905      - 2nd step:  fix some store dirs
1906        o seems to work somewhat, i.e. using ifort but not g77
1907        o likely cause are incomplete init. or recomputation
1908        o start verification/global_ocean.cs32x15/input_ad.thsice
1909    o pkg/obcs: add support for exch2
1910      - the position of the boundary and prescribed values are specified using
1911        a global domain with exch2 facets stacked
1912        - in x for N,S boundaries (like W2_mapIO=-1)
1913        - in y for E,W boundaries (so E,W boundaries do not overlap)
1914    o pkg/mdsio: add support for writing global sections with exch2
1915        file layout is as for obcs described above:
1916        - for x-z sections, facets are stacked in x (like W2_mapIO=-1)
1917        - for y-z sections, facets are stacked in y
1918    o pkg/thsice:
1919       - change a few routines for better vectorization: thsice_albedo.F,
1920         thsice_step_temp.F, and in thsice_calc_thickn.F. Results are
1921         not affected, but in particular the latter routine has changed
1922         dramatically (not necessarily easier to read now).
1923       - re-arrange calculation in THSICE_SOLVE4TEMP: move outside of i,j loops
1924       iteration loop and call to S/R THSICE_GET_BULKF & THSICE_GET_EXF.
1925    o verification/lab_sea:
1926      - overhaul of the forward model experiments. The main motivation
1927        for this revision is that lab_sea has proven quite fragile (when
1928        changing the sea-ice code, and switching platforms) to a point
1929        when failures were very hard to attribute to specific code problems.
1930      - the suspected reason for this fragility is noise amplification by evp so,
1931        to start with, we decided to replace evp with lsr in the main experiment.
1932      - the input.lsr experiment thus became obsolete and was removed.
1933      - it was replaced with the input.fd experiment that uses an
1934        analytical "free drift" solution as the ice velocity field.
1935      - Taken together, input (lsr), input.fd (free drift) and input.hb87 (evp)
1936        will hopefully allow us to discriminate problems due to dynamic solvers
1937        from problems due to the thermodynamic code. input.salt_plume (lsr) allows
1938        us to test additional options, along with the salt plume package.
1939      - Finally a pickup was generated (at the end of a one year run) to
1940        make the tests more representative of an actual model run. Previously
1941        the tests starting point was a 1m thickness of ice everywhere.
1942    o pkg/seaice:
1943      - introducing S\R seaice_freedrift.F that compute the
1944        analytical solution to an approximate ice momentum
1945        equation (i.e. the simple stress/coriolis balance).
1946      - define SEAICE_ALLOW_FREEDRIFT to trigger the computation
1947        of the free drift velocity field, and enable its use.
1948        To actually use the free drift solution as the model ice
1949        velocity field set SEAICEuseFREEDRIFT to .TRUE. in data.seaice.
1950    o move "useOASIS" from PARAMS.h to EEPARAMS.h and read it from "eedata"
1951    
1952    checkpoint62l (2010/10/04)
1953    o pkg/seaice:
1954      -fix the USE_ORIGINAL_SBI version (for variable freezing point);
1955      -use "celsius2K" in SEAICE_VARIABLE_FREEZING_POINT and in new
1956       version (with USE_ORIGINAL_SBI undef);
1957    o add hooks for new packages OASIS, the package will follow
1958      (hooks exclude the seaice pkg for now)
1959    o pkg/autodiff: ALLOW_AUTODIFF_WHTAPEIO
1960      Option to use mdsio_read_whalos.F/mdsio_write_whalos.F,
1961      rather than mdsio_readvector.F/mdsio_writevector.F, within
1962      adread_adwrite.F to read/write adjoint-related tapes to disk.
1963    o eesupp and pkg/mdsio: ALLOW_WHIO
1964      Option to write/read 2D fields to files including tiles halos.
1965      The main purpose is for adjoint related "tape I/O".
1966      The secondary purpose is for debugging phases.
1967      A word on those rather specifically intended purposes.
1968      The code was meant to be stripped down to the bare minimum.
1969      Typically, there is a unique and basic mapping to the global
1970      buffer (tile by tile, then proc by proc, then level by level), and
1971      byteswaps and meta-files are omitted. Indeed the (*_WH*) code is not
1972      meant to generate user friendly outputs of various shapes and forms.
1973      Rather it is intended, for the knowledgeabale developers,
1974      to be largely independent of the many mdsio options, to allow
1975      outputs of tiles+halos in debugging phases and in adjoint runs,
1976      and to allow some flexibility in tuning (adoint) I/O depending on each
1977      file system behavior. With regard to tuning, most of the potential knobs
1978      (to leave files open, to allocate the I/O indep. of usesinglecpuio,
1979      to specify directories, to specify the typical size of I/O calls, etc.)
1980      are not yet included, and will be added if they prove useful.
1981    o pkg/seaice:
1982       fix uninitialised arrays in USE_ORIGINAL_SBI version of seaice_solve4temp.F
1983    o pkg/seaice:
1984       new S/R seaice_solve4temp.F: this is the merged version of Ian Fenty
1985       code (seaice_budget_ice_if.F) which enable to recover old standard
1986       code (seaice_budget_ice.F) when option USE_ORIGINAL_SBI is defined.
1987       temporary: add "#define USE_ORIGINAL_SBI" at the top of seaice_solve4temp.F.
1988    o model/src (rStar):
1989       use simple average (not area weighted) of rStarFac at U,V point when using
1990       vectorInvariant and selectKEscheme=1,3 (consistent with mom. vertical advection)
1991       update output of exp. fizhi-cs-32x32x40 and fizhi-cs-aqualev20.
1992    
1993    checkpoint62k (2010/09/17)
1994    o adjoint
1995       * changed verification/global_ocean.cs32x15 ; adjoint now tests
1996         Adams-Bashforth 3 + NLFS + RSTAR
1997       * some more modifs required for ECCO-GODAE v4
1998    o pkg/seaice
1999       add SEAICE_AGE_VOL option to use volume instead of area for
2000       integrating SEAICE_AGE
2001    o model/src:
2002       first check-in of sigma & hybrid-sigma coordinate code ; also includes
2003       non-linear free-surface parts ; but pressure-gradient not yet coded.
2004    o pkg/ptracers:
2005       option for ptracer to convert Salt Relax into additional EmP.
2006        tested in exp. global_ocean.90x40x15.dwnslp (update output)
2007    
2008    checkpoint62j (2010/08/25)
2009    o pkg/ggl90:
2010       other minor changes: remove 3-D temp array gTKE (+ add argument myIter)
2011    o pkg/dic: car_flux.F, phos_flux.F
2012      - reduce number of exp-calls in order to improve performance
2013      - clean up a little (replace fields by their macros, etc., fix
2014        typo in CPP-flag)
2015    o pkg/ggl90: minor changes
2016      - GGL90diffKrS was removed --> always use GGL90diffKr
2017      - GGL90viscAr was removed --> replaced with GGL90viscArU, GGL90viscArV
2018      - hack of mxlMaxFlag=2 --> ensure mixing between first and second level
2019        (commented out for now)
2020      - change in max/min operations to ensure that smoothing is ok
2021      - smoothing of GGL90viscAr was moved to ggl90_calc.F (as done for GGL90diffKr)
2022      - always use diffKrNrT as background profile (i.e. never use diffKr field)
2023    o pkg/cfc: bug fix, AREA(i,j,1,bi,bj) -> AREA(i,j,bi,bj)
2024    o pkg/dic:
2025      - model/src/impldiff.F: if TARGET_NEC_SX, extend loop ranges for better
2026        vectorization
2027      - small bug fix in insol for the unlikely case of a cartesian grid
2028      - towards vectorizing the dic package: bio_export.F, car_flux.F, phos_flux.F
2029        + now vectorize, which also removes adjoint recomputations;
2030        + replace integer maksp1 by _RL maskp1
2031        + replace a**x by exp(x*log(a)) in phos_flux.F for speed
2032    
2033    checkpoint62i (2010/07/21)
2034    o pkg/flt:
2035      - with OBCS: stop floats which enter the OB region
2036    o model/src:
2037      - use tempVertAdvScheme & saltVertAdvScheme (instead of horizontal ones)
2038        for implicit vertical advection.
2039    o pkg/seaice:
2040     - account for melting in seaice age evolution.
2041     - remove double counting of seaice ridging effect on seaice age.
2042    
2043    checkpoint62h (2010/06/18)
2044    o pkg/exch2:
2045     - remove exch2_*xy_rx files: call was replaced with exch2_*3d_rx(myNz=1).
2046    o tools/genmake2
2047      - remove "-pdefault" option: redundant with the use of "packages.conf";
2048      - remove file pkg/pkg_default : set the default as a pkg group
2049        ("default_pkg_list") defined in pkg/pkg_groups;
2050      - fix for case pkg/pkg_depend is missing (was hanging before);
2051      - add option "-pgroups" to specify a different pkg_groups than the default.
2052    o verification/adjustment.cs-32x32x1:
2053       add a "minimal" set-up test (code_min & input_min) which only compiles
2054       eesupp/src and the 2 pkgs (exch2 & debug) which don't need model/src & inc.
2055    o tools/genmake2
2056      - extend pkg_depend rules to model & eesupp (e.g., if model depend on [pkg]))
2057      - fix details of checking for mnc & profile pkg when NetCDF is unavailable.
2058    o pkg/exf: merge exf_bulk_largeyeager04 into exf_bulkformulae because these
2059      files are nearly the same anyway.
2060      Step 1: make exf_bulkformulae look like exf_bulk_largeyeager04:
2061       - redefinition of tau(i,i) (by a factor of ustar)
2062       - 1./exf(Const/T) -> exf(-Const/T) (big change in the results)
2063       - replace rhonil by rhoConstFresh in computation of evap (bug fix)
2064       - replace u/vstress=tau*rd*ws*cw by tau*rd*u/vwind (changes results)
2065       - replace
2066         rd(i,j)= rdn(i,j)/(exf_one - rdn(i,j)/karman*psimh )
2067         shn    = sh(i,j,bi,bj)*rd(i,j)/rdn(i,j)
2068         by
2069         shn    = sh(i,j,bi,bj)/(exf_one - rdn(i,j)/karman*psimh )
2070         (changes results)
2071       -> exf_bulkformulae v1.22,
2072          update verification experiments lab_sea, offline_exf_seaice, seaice_obcs
2073          (lab_sea: output.hb87.txt 1.11, output.lsr.txt 1.25, output.salt_plume.txt 1.13,
2074                    output.txt 1.63
2075           offline_exf_seaice: output.seaicetd.txt 1.7
2076           seaice_obcs: output.txt 1.10)
2077      Step 2: do the actual merge and remove exf_bulk_largeyeager04.F
2078       -> exf_bulkformulae v1.23,
2079          unfortunately requires updating lab_sea.salt_plume (6 matching digits),
2080          and global_ocean.cs32x15.icedyn (only 11 matching digits)
2081      Also update output_adm of exp. lab_sea (all 4) and offline_exf_seaice.
2082    o adjoint of exch-1:
2083     - pass high-level EXCH S/R through TAF (eesupp/src/exch_ad_diff.list)
2084       (note: was already like this when using EXCH-2) and remove flow dir
2085       and hand-written AD version of high-level EXCH S/R (pkg/autodiff);
2086     - provide flow-dir for low-level exch1 S/R (eesupp/src/exch1_ad.flow);
2087     - update pkg/exch2 diff list.
2088    
2089    checkpoint62g (2010/05/19)
2090    o eesupp/src (exch-1):
2091     - split exch_rx.F into Forward S/R (exch1_rx.F) and Adjoint S/R (exch1_rx_ad.F)
2092       and remove argument "simulationMode"; same thing for all exch_*rx_cube.F
2093       (renamed to exch1_*rx_cube.F).
2094     - change accordingly exch_*_rx.template and AD version in pkg/autodiff
2095       to call new exch1 S/R ; update Makefile and .cvsignore.
2096     - replace call to exch2_xy_rx S/R with exch2_*3d_rx(myNz=1) (will remove
2097       exch2_xy_rx later)
2098      Note: after updating your code, need to run "make clean" in eesupp/src
2099    o test experiment bottom_ctrl_5x5:
2100       new output_adm.txt with fewer grdchk & less monitor output.
2101    o model/src:
2102      remove the call to ini_cori in initialise_varia.F (just keep the usual one
2103       in initialise_fixed.F). More consistent with coriolis & horizontal grid
2104       beeing treated in the same way (ini_grid is not called a 2nd time).
2105    o pkg/exf:
2106      - rewrite exf_bulk_largeyeager04.F for better vectorization, changes
2107      global_ocean.cs32x15/input.icedyn (11 digits of agreement), updated
2108      - fix adjoint (used worked for ALLOW_ATM_WIND defined, works for this now)
2109      - cosmetic changes to exf_bulkformulae.F to make it look more like
2110        exf_bulk_largeyeager04.F
2111    o eesupp/src (exch-1):
2112      - Fix AD EXCH code for 2-D domain special cases (Nx=1 or Ny=1).
2113      - Separate buffer filling and MPI sending: allow EXCH-1 to work for local
2114        array (non-shared) when using MPI+MTH. Also reduces number of BARRIER
2115        (even without using MPI).
2116      - Message mode: move RecvAck setting (indicator of buffer being ready)
2117        from send_put to recv_get S/R (was useless before, but not sure if
2118        it's much more useful now);
2119      - Switch the order of sync: MPI-proc 1rst and then threads;
2120      - take out spin-waiting code (#undef EXCH_USE_SPINNING), use BARRIER instead.
2121      - fix AD code for communication mode ='get' (but not used).
2122    o model/src:
2123      initialise dPhiHydX,dPhiHydY inside calc_grad_phi_hyd.F (so that TAF does
2124      not drop it in S/R mddynamics, producing NaN in hs94.1x64x5 AD-test exp).
2125    o utils/matlab/rdmnc.m: adapt to be able to use the generic matlab netcdf API
2126    o pkg/ctrl: require a specific set of control variables and exf-flags for
2127      adjoint of seaice (stop in ctrl_check.F if conditions are not satisfied)
2128    o model/src:
2129     a) 1rst version of a new driver S/R to turn-off output freq and flags after the
2130       1rst forward sweep, to avoid over-writing output files during recomputations
2131       recomputations (& grdchk); called from cost_final.F (& ctrl_init_ctrlvar.F ?)
2132     b) 2nd version:
2133      - add specific pkg S/R for seaice & ptracers (called from S/R TURNOFF_MODEL_IO);
2134      - switch-off more output flags (exf_monFreq, chkPtFreq, dumpInitAndLast,
2135         writePickupAtEnd) + seaice & ptracers output;
2136      - do not switch off MNC flags (otherwise, won't get admonitor netcdf file)
2137    o model/src:
2138      - new S/R rotate_uv2en_rl (..._rs) that rotates vector fields.
2139    o pkg/exch2:
2140      - remove "simulationMode" from arg. list of S/R EXCH2_RX1,2_CUBE ;
2141      - add argument "signOption" to EXCH2_RX1_CUBE (will be needed for SM exch).
2142    o pkg/autodiff & exch2:
2143      process exch_uv_agrid_3d_rx.f & exch2_uv_agrid_3d_rx.f through TAF
2144      (for now, only if ALLOW_EXCH2 is defined).
2145    o pkg/autodiff:
2146      - include PACKAGES_CONFIG.h in exch*ad.flow & exch*ad.F
2147        (not supposed to be in CPP_OPTIONS.h) to get ALLOW_EXCH2 defined correctly.
2148       + clean-up comments (_RS is not always real*4)
2149      - fix bug in ADEXCH_UV_3D_RX (without EXCH2, was calling the forward exch S/R)
2150      - add a stop in ADEXCH_UV_AGRID_3D_RX if trying to use it with EXCH2:
2151        was calling a forward exch2, which is wrong ; used in SEAICE & EXF pkgs.
2152    o testreport (AD-tests):
2153      no longer link files from dir "../input" (1rst link files from
2154      "../input_ad.[xx]" if secondary test "xx" and then from "../input_ad")
2155    
2156    checkpoint62f (2010/04/29)
2157    o model/src/the_main_loop.F:
2158      adjust store directives for seaice evp and multicategory according to
2159      pkg/ecco/the_main_loop.F
2160    o adjoint:
2161      global_sum_ad was incomplete (noted many times by many people ;)
2162      nice description by Jean U. as follows:
2163      * allreduce(var) in global_sum.F can be interpreted as
2164        reduce(sum) followed by broadcast of sum.
2165      * The adjoint of that is
2166        sum(adjoint) followed by broadcast(summed adjoint value)
2167        or in other words, allreduce(sum, adjoint vars)
2168      We were missing the sum(adjoint)!
2169      Benign, except(!) for "global" scalars appearing in tile loops (bi,bj)
2170      (noted by J.M. Campin, e.g., in cost_ssh_mean, variable offset).
2171      The fix should produce 16-digit accuracy between
2172      single-CPU multi-tile (e.g. nSx=2, nPx=1) and
2173      multi-CPU single-tile (e.g. nSx=1, nPx-2)
2174      We'll probably change this yet again shortly
2175    o eesupp/src:
2176      - fix global_sum_r4 (wrong from previous modif in Jun 2009; ever used ?)
2177    o pkg/icefront
2178      - ALLOW_SUBGLACIAL_RUNOFF option adds capability for time-evolving
2179        specification of addmass array based on a 2D field, which is added
2180        at bottommost wet level at each horizontal location.
2181    o model/src:
2182     horizontal grid initialisation (other than curvilinear): add code for Exch2 IO
2183     layout; (not always compatible with delX,delY setting; commented out for now).
2184    o pkg/exch2:
2185     change tile to processor setting (case nSy*nPy > 1): allows default model mapping
2186     (myX and myYGlobalLow) to be used for simple (1 facet, no blank tile) config.
2187    
2188    checkpoint62e (2010/04/15)
2189    o pkg/obcs:
2190      - fix wrong index in OBCS_SPONGE_V for Eastern-OB (reported by David Hebert).
2191    o pkg/dic:
2192      -fix bug in fe_chem.F for multi-tile (nSx*nSy > 1) set-up;
2193        (note: not presently tested in any forward verification exp.)
2194       update tutorial_global_oce_biogeo AD output file.
2195    o pkg/exf:
2196      - account for the variation of albedo as a function of zenith angle
2197        by defining ALLOW_ZENITHANGLE in EXF_OPTIONS.h
2198    o build_options:
2199     - rename "linux_ia64_ifort+mpi_ice_nas" to "linux_amd64_ifort+mpi_ice_nas"
2200    o pkg/dic:
2201      change DIC atmos-CO2 box (method 3, dic_int1=3) initialisation & restart:
2202      - use binary pickup file for restart;
2203      - initialise atmos-CO2 box from dic_pCO2 parameter;
2204      - fix multi-threaded.
2205    o pkg/rbcs:
2206     - clean-up RBCS code: add RBCS_OPTIONS.h file ; fix multi-threaded ;
2207       change (+ fix IO calls) type of array RBC_mask from _RL to _RS.
2208     - add RBCS to exp4 passive tracer 01 (rbcs was previously untested)
2209       and update output.txt
2210    o pkg/kpp:
2211     - add diagnostics for KPP non-local flux of Temp, Salinity and pTracers;
2212     - change diagnostic of KPP non-local term: output average of KPPghat*KPPdiffKzS
2213       (= ratio of KPP non-local (salt) flux relative to surface-flux) when
2214       using pkg/timeave & pkg/diagnostics (diag 'KPPghatK' replaces 'KPPghat ');
2215     - change pkg/offline to read-in average KPPghat*KPPdiffKzS from file
2216       KPP_ghatKFile (instead of the average of KPPghat from file KPP_ghatFile).
2217    o pkg/offline:
2218      fix bug in S/R OFFLINE_FIELDS_LOAD regarding surfaceForcing conversion factor
2219      (bug was added in version 1.10 on 2007-08-23).
2220    o pkg/offline:
2221      - no need to specify periodicExternalForcing, etc ... to use offline pack
2222      - offline input files no longer just single prec --> parameter offlineLoadPrec
2223    o verification/lab_sea:
2224      change AD test to multi-tile setup and update all 4 AD output.
2225      NOTE: while cost function values remain very similar,
2226      gradients are very different, although gradient checks are self-consistent
2227      Should try to get to the bottom of this (cost function summation order?)
2228    o pkg/dic:
2229      in carbon_chem.F, replace log10 (AUTODIFF) with explicit form to avoid
2230      a weakness of TAF that drops part of double precision in log10 derivative.
2231      <= changes removed since problem has been fixed in current TAF version 1.9.71
2232      update AD output of exp. tutorial_dic_adjoffline & tutorial_global_oce_biogeo.
2233    o pkg/ecco:
2234      add missing "_d 0" in cost_readers.F, cost_readtopex.F & cost_readtopexmean.F
2235      update all 4 lab_sea AD output.
2236    
2237    checkpoint62d (2010/03/22)
2238    o build_options:
2239      remove '-r8' (and '-i4') from linux_*pgf and linux_*ifort optfiles.
2240    o remove unbalanced quote (single or double) in commented line of source code
2241      (may cause some warning with some preprocessor/makedepend versions).
2242    o pkg/seaice:
2243      fix seaice_model.F for adjoint (gael) and update AD results of experiments
2244       lab_sea (std + evp + noseaicedyn) and offline_exf_seaice.
2245    o testreport:
2246      add option '-runonly' (short: '-ro') to just do the run part (without make).
2247    o eesupp: remove JAM communication code (obsolete).
2248    o add option to genmake2 & testreport to switch "_RS" type to "real*4"
2249      (if allowed in CPP_EEOPTIONS.h); update default CPP_EEOPTIONS.h and return
2250      to default CPP_EEOPTIONS.h for exp. inverted_barometer & solid-body.cs-32x32x1
2251      (update also the output).
2252    
2253    checkpoint62c (2010/03/02)
2254    o tools/build_options :
2255       move (some) old optfiles from build_options/ to build_options/unsupported/
2256    o model/src and pkg/exf
2257       surface relaxation -- separating data and data.exf options
2258       The point is to ensure that we specify the surface relaxation
2259       either in data or in data.exf (but not half and half) and to
2260       avoid an accidental relaxation to 0 (which happened if a time
2261       scale was specified but the file name was left empty)
2262    o model/src model/inc and pkg/mom_common
2263       ALLOW_3D_VISCAH/ALLOW_3D_VISCA4 => 3D specification of Viscosity
2264       => addition to the viscosity field as computed by others schemes
2265    o tools/build_options:
2266      - rename "_generic_mpi" -> "+mpi_generic" (like other "+mpi" optfile)
2267        but keep the former optfile for few weeks for smooth transition
2268    o pkg/ecco
2269      - allow user defined cost function contributions
2270         CPP: ALLOW_USERCOST_CONTRIBUTION
2271         USAGE: compute contributions in cost_usercost_all.F
2272      - note: this is identical to what ALLOW_GENCOST_CONTRIBUTION once was.
2273          the two options are complementary.
2274    o pkg/smooth
2275      - migration from contrib to the main repository
2276    
2277    checkpoint62b (2010/01/26)
2278    o pkg/monitor:
2279      - change back mon_printstats_rl.F & mon_stats_rl.F and add a stop
2280        (in case someone forgot to update customized pieces of code)
2281    o nonHydrostatic:
2282      - add Non-hydrostatic free-surface form (selectNHfreeSurf=1)(not fully tested);
2283      - add a simple 2-D experiment (short_surf_wave) to test it.
2284    o pkg/icefront:
2285       adding the shell of, and the hooks to, a new package that
2286       will model melting and freezing of vertical glacier ice fronts
2287    o momentum:
2288      add diagnostics of momentum tendency from Hydrostatic pressure gradient
2289       (without surf.pressure term: would need a 2nd filling since implicit term).
2290    o add 3 "_d 0"s so that fizhi compiles with xlf on iblade, and replace
2291      two " &end" by " &" (in fizhi-cs-*) because S/R NML_SET_TERMINATOR
2292      cannot deal with the former
2293    o cleaning:
2294      - remove all (except OpenAD) old TLM output from results_ad dirs.
2295      - remove unused S/R (MDSWRITEMETA, DIAGNOSTICS_ADD2LIST, old DFILE IO S/R)
2296      - comment out maskH definition (replaced by maskInC)
2297    o pkg/monitor:
2298      - change mon_printstats_rl.F & mon_stats_rl.F (were similar to mon_writestats_rl
2299        & mon_calc_stats_rl) to be the RL equivalent of mon_printstats_rs & mon_stats_rs.
2300    
2301    checkpoint62a (2010/01/15)
2302    o model/src:
2303      - bottom pressure diagnostic: correct for r* (when nonlinFreeSurf >= 4)
2304    o pkg/diagnostics:
2305      - add optional level number diagnostics (i.e., level number to be define
2306        explictly with S/R DIAGNOSTICS_SETKLEV) with parser-code(10)="X".
2307      - strictly check for valid parser-code(10) ;
2308      - check if adding diag to the list from the right place.
2309    o pkg/longstep:
2310      - change parameters and fix tracer conservation with rstar/nonlinear free surface
2311    o diagnostics:
2312     - in all pkgs, replace remaining calls to old S/R DIAGNOSTICS_ADD2LIST with newer
2313       S/R DIAGNOSTICS_ADDTOLIST ; fix seaice VICE diagnostics.
2314    o pkg/diagnostics:
2315     - Add option for writing vertical integral (sum of selected levels) of an output
2316        field instead of writing output field levels. Activate this option on a per
2317        output-file basis, by setting the 2nd character of fileflag to 'I'.
2318     - Add field-specific information relative to level integral in 3rd postion
2319        of parser diagnostics code (gdiag): " "=cumulate levels, "R"=integrate
2320        vertically (x level-thickness x hFac), "r"=same but without hFac.
2321    o do_the_model_io:
2322      - pass end-of-model-run flag as argument, from forward_step to diagnostics_write:
2323        in case useSIGREG, will write (averaged) diagnostics (if dumpAtLast) before
2324        writing pickups and stopping.
2325    o pkg/diagnostics (for now, only with mdsio):
2326      - write time information to meta file (and modify accordingly rdmds.m) :
2327        time-averaged diagnostics output: write starting and ending time of the
2328        time-averaging interval ; snap-shot diagnostics output remains unchanged;
2329    o pkg/timeave:
2330      - S/R TIMEAVE_NORMALIZ: change size of cumulated-time array (was previously
2331        always Nr), now assumed to be equal to number of levels of averaged field;
2332        only used for DIC_COST monthly mean arrays: this fixes dic_aver_final.F
2333    o pkg/sbo:
2334      - fix ocean bottom pressure global-average & 2-D time-ave output (was
2335        neither initialised nor filled).
2336      - add starting iteration in suffix of global-average output file
2337        (to avoid over-writing the file after a restart)
2338      - use standard MDSIO pkg S/R instead of SBO_WRITEVECTOR (fix byte-swap Pb).
2339    o time-average:
2340      - use simple cumulative-time array (no k index) in all pkgs: {PKG}_timeAve(bi,bj)
2341        (pkgs: aim_v23, bulk_force, dic, gmredi, kpp, land, ocn_compon_interf,
2342         ggl90, my82, opps, pp81, ptracers, sbo, seaice, shelfice, thsice)
2343        this fix DIC_COST cumulative-time array (previously: bi,bj,k)
2344      - fix 1rst call (nIter0) snap-shot output and accumulation (pkg/shelfice)
2345      - fix missing accumulation for pkg/opps.
2346      - cumulate fields only if doing time-ave output ({PKG}_taveFreq > 0)
2347         (pkgs: ptracers, kpp, ocn_compon_interf, ggl90, my82, pp81);
2348      - fix initialisation of time-ave vars and do only full time-step increment
2349        (i.e.: no first & last "half time-step") (pkgs: ggl90, my82, opps, pp81);
2350    o pkg/layers:
2351      - use standard RW pkg S/R to write the output
2352        and remove local write_fld version (which had a problem).
2353      - use simple cumulative-time array (no level index) to fix time-ave S/R calls.
2354      - fix LAYERS_CALC argument list.
2355    o pkg/timeave:
2356      - store cumulative-time in a simple tiled array (drop the level index)
2357      - add new S/R (TIMEAVE_NORMALIZE) which uses simple cumulative-time array.
2358    o pkg/ocn,aim_compon_interf
2359      - changes for multi-threaded coupled run. (tested with ifort-11 on danton)
2360    
2361    checkpoint62  (2009/12/23)
2362    o switch on useOBCSbalance in tutorial_plume_on_slope exp. and update output.
2363        (was not previously tested in any other exp.)
2364    o pkg/monitor:
2365      - clean-up _RL/_RS version: add specific S/R for statistics with mask & volume:
2366        mon_writestats_rl/s,F mon_calc_stats_rl/s.F ; will keep the old one
2367        (mon_printstats_rl/s,F mon_stats_rl/s.F) just for bare statistics.
2368      - use hFac & 2-D mask (instead of 3-D mask + hFac in previous mon_stats_rl.F).
2369      - change del2 calculation.
2370      - use interior masks (instead of maskH, <- to be remove).
2371      - shorter monitor suffix for forcing stats ("forcing" instead of "extforcing").
2372    o mask & obcs:
2373      - define 2-D "interior" masks (i.e., zero beyond OB) at 3 locations (C, W & S).
2374      - move global area computation from ini_masks_etc.F to ini_linear_phisurf.F
2375        (called after packages_init_fixed)
2376    o pkg/obcs:
2377      - move bi,bj loops into obcs_calc, so obcs_prescribe_read is called only once.
2378        Fixes bug in obcs+exf with nSx*nSy.GT.1
2379      - fix multi-tile handling in obcs balance code
2380    o nonHydrostatic:
2381      - Implement AB-3 for non-hydrostatic vertical momentum ;
2382        (change ordering of var. stored in pickup file when using NH)
2383      - move NH code from solve_for_pressure.F to 2 new S/R: PRE_CG3D & POST_CG3D.
2384      - add 2-D field to store Hydrostatic Surface Pressure adjusment from cg3d_x
2385        (in prep. for new NH free surface form).
2386    o pkg/obcs:
2387      add files & OB-variables for wVel (Non-Hydrostatic) with useOBCSprescribe
2388    o model/src:
2389      fix 2-D solver initialisation for deep-atmosphere (p-coord) with topography
2390    
2391    checkpoint61z (2009/12/01)
2392    o nonHydrostatic:
2393      Fix missing vertical flux of vert. momentum near surface (k=1). This fixes
2394        a spurious source of energy in simple baroclinic adjusment test case.
2395      Update all non-hydrostatic exp output.
2396    o model/src (3-d solver):
2397      Change again 3-D solver free-surface RHS term when exactConserv=T:
2398        simpler, consistent with exactConserv, and works with implicDiv2Dflow < 1
2399        (which was not the case with previous formulation).
2400      To recover previous version, just reset "oldFreeSurfTerm" to previous value.
2401      Affects results of exp. global_ocean.cs32x15.viscA4 & hs94.cs-32x32x5.impIGW.
2402    o nonHydrostatic:
2403      - compatible with implicDiv2Dflow < 1 ; + implement implicit factor
2404        for Non-Hydrostatic pressure gradient (similar to implicSurfPress).
2405      - change 3-D solver to work with r* (for now, only with linear free-surf.)
2406      - add few debug diagnostics (cg3d_x, residual)
2407    o model/src:
2408      fix missing EmPmR in 3-D solver RHS (was in cg2d_b but missing in cg3d_b).
2409        update output of exp. global_ocean.cs32x15.viscA4
2410    o update output of exp. global_ocean.cs32x15.icedyn after removing
2411      #define SEAICE_OLD_AND_BAD_DISCRETIZATION from SEAICE_OPTIONS.h
