4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o AD_CONFIG.h file:
8     - in genmake2: remove "#undef ALLOW_ECCO_OPTIMIZATION" from AD_CONFIG.h;
9     - remove #include "AD_CONFIG.h" from all included OPTIONS files and
10       add it explicitly in each fortran src file where it is needed.
11       motivation: header file AD_CONFIG.h is generated/modified after "make depend"
12       thus introducing potentially wrong dependency; therefore, better to include
13       it only where it's really needed, and after any other included OPTIONS file
14       (less tempting to bring conditional includes according to ALLOW_ADJOINT_RUN
15       or ALLOW_TANGENTLINEAR_RUN).
16    
17    checkpoint63p (2012/07/06)
18    o pkg/autodiff:
19      - rename S/R INI_AUTODIFF to AUTODIFF_INIT_VARIA ;
20      - create new header file "AUTODIFF_PARAMS.h" for pkg/autodiff parameters
21        which are now read from new parameter file "data.autodiff" (inAdExact
22        previously in "data", use{KPP/GMRedi/SEAICE}inAdMode previously in data.pkg)
23      - add file "data.autodiff" in all verification/*/input_ad/ directories.
24      - add run-time parameter to turn On/Off SEAICEuseFREEDRIFT in adjoint/forward
25        mode (used in global_ocean.cs32x15.seaice_dynmix test exp.)
26    o verification/tutorial_tracer_adjsens/
27      - add extra sub-verification which uses "SOM" advection scheme
28        (2nd Order-Moment Advection Scheme, Prather Limiter) with
29          #define GAD_ALLOW_TS_SOM_ADV in GAD_OPTIONS.h
30        and in data:
31          multiDimAdvection=.TRUE.,
32          tempAdvScheme=81,
33          saltAdvScheme=81,
34    o model/src:
35      - introduce ALLOW_BALANCE_RELAX which allow the removal
36       of the global mean of relaxation terms by setting
37       balanceThetaClimRelax and balanceSaltClimRelax
38      - disable balanceEmPmR and balanceQnet in the case when useSeaice.
39       This case is now treated appropriately in seaice_growth.F
40    o pkg/seaice:
41      - do balanceEmPmR and balanceQnet based on the net fluxes
42        (SItflux) that enter the ocean+ice system rather than QNET
43        and EMPMR. Works best in real fresh water.
44      - SIatmFW, SIatmQnet, and SItflux computations had to be moved
45        out of the diagnotics bloc, and stored in global arrays.
46    
47    checkpoint63o (2012/06/29)
48    o vertical mixing schemes:
49      - remove unused S/R CALC_BUOYANCY (left from branch-atmos merging)
50      - replace computation of density (in Function STATE1, opps_calc.F) by a call
51        to S/R FIND_RHO_SCALAR
52      - pass sigmaR to S/R PP81_CALC, MY82_CALC (but not yet used) and to GGL90_CALC
53        and use it for N^2 calculation in ggl90_calc.F (save 2 density computations);
54        affects output (vermix.ggl90) at truncation level.
55    o testreport:
56      - change adjustment of SIZE.h for mpi+mth testing: preserve enough tiles
57        (nSx,nSy) for the number of threads (from eedata.mth)
58    o model/src:
59      - remove 2nd set of calls at the top of initialise_varia.F (Adjoint part)
60        related to Non_Lin Free-Surf or Bottom-Control (but not longer necessary).
61    o verification/tutorial_tracer_adjsens/
62      - compile with ALLOW_CG2D_NSA
63      - run with nonlinFreeSurf=3
64      - update reference output_adm.txt
65    o tools/genmake2:
66      - add "-DHAVE_NETCDF" to the DEFINES list when NetCDF is available ;
67        refine usePROFILES switching off (only when NetCDF is not available).
68    o verification (atmospheric set-up):
69      - change eosType='IDEALGAS' to eosType='IDEALG' to match variable declaration
70    o pkg/profiles : refine profiles and files handling.
71    o model/src and pkg/ecco : introduce run-time switch usePROFILES.
72    o model/src/the_main_loop.F, forward_step.F and pkg/exf/EXF_OPTIONS.h :
73      - changes to use model/src/the_main_loop.F rather than the ecco version
74        in ecco type adjoint runs.
75    o model/src:
76      - move computation of recip of grid distance & area from INI_MASKS_ETC to INI_GRID
77      - move setting of h0Fac[C,W,S] from INI_LINEAR_PHISURF to INI_MASKS_ETC
78      - update_masks_etc.F: rename SMOOTH*_R4,R8 function to the corresponding type (RS,RL)
79    o model/src:
80      - fix S/R UPDATE_CG2D for ALLOW_DEPTH_CONTROL case (was empty before);
81        update output of test experiment bottom_ctrl_5x5.
82    o pkg/generic_advdiff:
83      - implement vertical bi-harmonic diffusion (for now, only for T & S and
84        only explicitly).
85    o verification/bottom_ctrl_5x5/
86      update reference output (results changed quite some time ago,
87      not sure when; but new reference results look ok in terms of grdchk)
88    o verification/1D_ocean_ice_column/
89      For verification purposes, the exact adjoint rather than an approx.
90      should be used (e.g., to comare against F.D. or TLM).
91      removed autodiff_inadmode*_ad.F routines in code_ad/
92      Update results/ accordingly.
93    o pkg/cal:
94      - change cal_getdate.F so that output date is function of input time only
95        (less ambiguous, not mixed up with input iteration number).
96      - fix calendarDumps for non-zero phase-lag (S/R CAL_TIME2DUMP).
97    o pkg/diagnostics:
98      - implement calendarDumps also for stats-diags
99      - implement calendarDumps also for snap-shot output (negative freq)
100      - for now, ignores calendarDumps if non-zero phase-lag.
101    
102    checkpoint63n (2012/06/04)
103    o model/src:
104      - recompute rSurfW & S to ensure consistent column thickness (needed for rStar)
105        between Sum_k(hFac*drF) and rSurf-rLow, for now only when using pkg/shelfice;
106      - use h0FacC, W & S to compute hFac_surfC, W & S in calc_surf_dr.F (more
107        similar to calc_r_star.F); update results of experiment internal_wave and
108        tutorial_global_oce_in_p (affected @ truncation level).
109    o pkg/shelfice:
110      - add parameterisation of advective-diffusive flux into the ice shelf
111        according to Holland and Jenkins (1999), eq.22-33, as suggested by Jan De Ryd
112      - simply eps3/3a computation
113    o eesupp:
114     - add new CPP option (DISCONNECTED_TILES) to disconnect tiles (no exchange
115       between tiles, just fill-in edges assuming locally periodic subdomain) and
116       add corresponding exchange subroutines (EXCH0);
117     - new CG-solver version (_EX0) for disconnected-tiles special case.
118    o model/src (CG-solvers):
119     - modify Single-Reduction version (CG2D_SR) in case cg2dMaxIters is reached
120       (similar final residual output and max-Iter number as with standard version);
121     - allows to store and use lowest-residual solution (standard & _SR versions);
122     - cleaning up (remove old, commented out code, LETS_MAKE_JAM ...).
123     - by default, also compile CG2D_SR version (define ALLOW_SRCG in CPP_OPTIONS.h)
124    o eesup/src:
125     - global_vec_sum.F cleaning: add a BARRIER ; update comments ; remove ndef
126       ALWAYS_USE_MPI (no longer needed after fixing usingMPI settings - March 2012)
127    o pkg/salt_plume added to lab_sea/input_ad.noseaicedyn
128    
129    checkpoint63m (2012/04/27)
130    o pkg/shelfice:
131     - account for partical cells in surface level below ice-shelf for hydrostatic
132       pressure calculion (set uniformFreeSurfLev to F); update isomip experiments.
133    o ad test experiments:
134     - update and rename to "ad_optfile.local" local AD-optfile specific to a
135       particular adjoint verification experiment (in verification/*/code_ad/)
136    o pkg/seaice & pkg/exf:
137     - Part two of ECCO-CLIVAR code merges.
138       Completes merge of seaice area relax. code.
139       Requires unified CPP option EXF_ALLOW_SEAICE_RELAX
140       to be set in EXF_OPTIONS.h since this pkg controls its I/O
141       (and avoids second CPP option in SEAICE_OPTIONS.h)
142     - change default value of costIceStart & costIceEnd to a valid date.
143     - add snowPrecip to HSNOW in seaice_growth
144    o pkg/ptracers:
145     - move ptracers summary and setup check into separated S/R ; add a check for
146       valid PTRACERS_Iter0 value (error+stop or just warning).
147    o pkg/cal (+ pkg/ecco):
148     - avoid calling a S/R with 2 times the same arg (FWD: unless both are only used
149       as input; and for AD, unless both are not differentiable (e.g., k index)).
150    o model/src:
151     - define internal flag "uniformFreeSurfLev" (=T when free-surface level-index
152       is everywhere k=1) to speed-up some calculations (by pass kSurf reference);
153       temporary set to usingZCoords value (to be changed to F when using shelfice).
154     - hydrostatic pressure: implement partial cell near the surface also for
155       Z-coordinates (for the case where uniformFreeSurfLev=F); replace test on
156       usingZCoords with test on uniformFreeSurfLev where needed (in NonHyd code).
157    o pkg/ctrl/ctrl_init.F:
158     - add a formal parameter to s/r ctrl_init_rec to print
159       xx_$(ctrl_valiable)_file for easier debugging
160     - move call of cal_* routines into the if-block where they are really
161       needed so that xx_$(ctrl_variable)_period can be 0 or -12 without having
162       to specify a startdate
163    o pkg/seaice:
164     - update comments in SEAICE_OPTIONS.h (+ similar update of lab_sea/code and
165       global_ocean.cs32x15/code versions).
166     - turn on seaice Multi-category (in data.seaice, SEAICE_multDim=7) for
167       verification experiment global_ocean.cs32x15.seaice and update results.
168    o pkg/exf:
169     - new S/R EXF_GETFIELD_START to return starting-time of a forcing field
170       (according to useExfYearlyFields).
171    o pkg/cal:
172     - move calendar setting & summary (previously in cal_readparams.F) into new
173       S/R CAL_INIT_FIXED to be called later in the initialisation process, once
174       length of the simulation is set (after SET_PARMS call); This is an attempt
175       to fix Pb when, e.g.: pkg/longstep, modifies the length of the run.
176     - For safety: keep a record of pkg/cal parameter settings status
177               to allow to STOP if one pkg/cal S/R is called too early.
178     - add a stop in all basic pkg/cal subroutines if called before setting is done.
179     - modify cal_getdate.F: stop when nothing was returned;
180       if called with myIter=-1, simply retrun modelBaseDate (1,2 = startDate_1,_2);
181       this allows to remove "cal.h" from seaice_read_parms.F & init_mnc_vars.F.
182    
183    checkpoint63l (2012/04/04)
184    o pkg/bbl:
185      - fix call to FIND_RHO_2D in bbl_calc_rho.F (case multi-tiles per proc);
186        update global_with_exf output.yearly.txt file.
187    o pkg/cal:
188      - start to clean-up cal_set.F ; fix for the case where baseTime is non-zero.
189      - remove 2 unsused and very short (1 line only) functions ;
190      - remove unsused subroutines from AD-Diff list.
191    o model/src:
192      - start to implement clean wait to stop in initialization S/R (config_check.F,
193         packages_check.F, ini_parms.F and pkg/obcs/obcs_check.F + pkg/mypackage)
194    o folowing PRINT_MESSAGE changes:
195      - remove reminder multiple print to the same file (STDOUT) when multi-threads.
196    o pkg/bbl:
197      - modification so it can work with z*
198      - replace deltaT with dTtracerLev(k) for asynchronous time stepping
199      - global_with_exf/input.yearly verification; changes output.yearly.txt
200    o eesupp/src:
201      - PRINT_MESSAGE: use OpenMP critical instruction (similar to PRINT_ERROR);
202        writing to unit 0 (if unit=errorMessageUnit) extended to the case myThid=1
203      - CHECK_THREADS: specific code if using OpenMP threading: improve checking of
204        # of threads across processors (e.g., different env OMP_NUM_THREADS setting)
205      - improve special preliminary call to EESET_PARMS (if eedata is read 2 times).
206      - when using MPI, always set usingMPI=T ; set default accordingly and stop
207        if not consistent.
208      - ALL_PROC_DIE: add a BARRIER after MPI_FINALIZE call ; skip this when thread
209        argument is zero (in case called within single-thread section).
210    o pkg/fizhi:
211        clean-up turbulence cold-start switch: decided in fizhi_init_vars.F, stored
212        in common bloc (fizhi_coms.h) and then passed as argument up to S/R TURBIO.
213    o pkg/exch2:
214      - add argument "updateCorners" to S/R exch2_get_uv_bounds (enable to
215        activate EXCH_IGNORE_CORNERS in vector EXCH S/R).
216      - switch 1rst EXCH call to IGNORE_CORNERS (instead of UPDATE_CORNERS)
217        but keep the 2nd with UPDATE_CORNERS: this prevents overwriting good data
218        with bad ones coming from a not-yet-updated halo.
219        This should fix the problem when sNx <> sNy and GCD(sNx,sNy) < 2*Olx.
220    o pkg/frazil:
221        move FrzForcT diag from frazil_diagnostics_state.F to frazil_calc_rhs.F
222        http://mitgcm.org/pipermail/mitgcm-devel/2012-March/005384.html
223    o model/src/config_check.F: add a check for OLx>sNx/OLy>sNy
224    o verification/lab_sea
225      * #undef SEAICE_EXCLUDE_FOR_EXACT_AD_TESTING
226      * #define ALLOW_SST_CONTROL & ALLOW_SST_CONTROL
227      * nTimeSteps 3 -> 4
228      * changed reference output accordingly
229    o pkg/ctrl:
230      * fix ctrl_get_gen for xx_sst, xx_sss
231    o pkg/fizhi:
232      - fix 2 calls to S/R GRD2MSC (argument igrd) in update_earth_exports.F
233        update results of exp. fizhi-cs-32x32x40 (fail with only 6 digits for cg2d)
234      - by default, use new version of S/R GETPWHERE (#define TRY_NEW_GETPWHERE);
235        fix few out-of-bounds indices in referencing vars (initialise igrd to 1);
236        clean-up fizhi_turb.F (remove unused & uninitialised qdiaglsm array).
237    o pkg/gmredi:
238      - add diagnostic of Redi (main diagnonal) vertical diffusive flux of Temp
239    o pkg/fizhi:
240      - fix few initialisation and multi-tile Pb: aqualev & gridalt now pass the
241        (old)aces open64 tuv test.
242    o pkg/icefront: fix bug and reorder loop in icefront_init_varia.F
243    o pkg/mom_vecinv:
244      - fix 1 loop range in mom_vecinv.F to be like all the other loops which
245        set/update gu,gv/Diss (fix Pb of uninitialised fVerUkp in admom_vecinv
246        with non-lin free-surf).
247    o model/src: move k-loop outside of i/j-loops when (re-)computing R_low
248      in ini/update_masks_etc.F in order to avoid -O3 optimization problems with
249      some compilers (gfortran 4.6.0 on MacOS)
250    o momentum:
251      - separate fVer?(:,:,kUp) & fVer?(:,:,kDown) in argument list of MOM_FLUXFORM
252        & MOM_VECINV subroutines (to help TAF). This fixes Pb of uninitialised
253        fVer?(kUp) in admom_fluxform with non-lin free-surf or bottom control.
254    
255    checkpoint63k (2012/03/17)
256    o model/src:
257       - selectAddFluid (ALLOW_ADDFLUID): add missing term in horizontal momentum
258         flux-form (mom_fluxform.F) and vertical momentum (calc_gw.F) equations.
259       - SOLVE_DIAGONAL: switch default to use adjoinable & vectorized version
260         (#undef SOLVE_DIAGONAL_LOWMEMORY); update output of exp. front_relax.bvp.
261    o model/src: solve_*diagonal.F
262       - replace division with multiplication by inverse (similar to original version)
263         update output of AD exp. global_ocean.90x40x15.
264       - fix pkg/gmredi/gmredi_calc_psi_bvp.F & pkg/ggl90/ggl90_calc.F
265         to enable the use of the vectorized & differentiable solve_tridiagonal.F
266       - test exp. global_ocean.90x40x15/input_ad: switch to advection scheme 20 for
267         vertical advection (to get solve_tridiagonal tested in AD mode).
268    o pkg/seaice: ECCO-CLIVAR merge:
269      1. seaice AREA relaxation
270         * CPP option: SEAICE_ALLOW_AREA_RELAXATION
271         * runtime flag: SEAICE_tauAreaObsRelax
272      2. modified global mean cost imbalance code: CPP option
273          ALLOW_SSH_GLOBMEAN_COST_CONTRIBUTION
274    o another iteration on solve_*diagonal.F
275       Make choices independent of AUTODIFF
276       Default will be the adjoinable vectorized version.
277       Alternative choices are:
278       * non-adjoinable original version with low memory footprint:
279         #define SOLVE_DIAGONAL_LOWMEMORY
280       * still adjoinable but does not vectorize (k as inner-most loop):
281         #define SOLVE_DIAGONAL_KINNER (keeping SOLVE_DIAGONAL_LOWMEMORY undef)
282    o testreport
283     - add option to use a home made wrapper around "make"
284     - remove MITGCM_IEEE env. variable (no longer active)
285    o pkg/shelfice
286     - improve computation of friction velocity for velocity dependent
287       exchange coefficients: include velocities into SHELFICEBoundaryLayer
288       block to average velocities vertically
289     - add TAF store directives for SHI_ALLOW_GAMMAFRICT
290    o Modify diagonal solvers, now three versions (upon request):
291      #ifndef SOLVE_DIAGONAL_AUTODIFF
292        1. default version (dating back a while ago)
293      #else /* def SOLVE_DIAGONAL_AUTODIFF */
294      # ifdef SOLVE_DIAGONAL_KINNER
295        2. adjoinable version with k-innermost loop (G. Forget)
296      # else
297        3. adjoinable vectorized version of 2.
298      # endif
299      #endif /* SOLVE_DIAGONAL_AUTODIFF */
300      All flags are currently set within routines, but could/should be moved to CPP-options.
301      Array bounds for 1. are as before, for 2.,3. cover the entire domain
302      (could be changed for 1. too).
303    o verification/lab_sea (fwd):
304      - update the 4 fwd lab_sea test experiment: no longer SEAICE_GROWTH_LEGACY,
305        use 7 categories (except hb87), new solve4temp params (except salt_plume),
306        constant salinity (=4) or variable salinity (salt_plume) done through
307        SItracer.
308    o pkg/seaice:
309      - rename parameters: SIsalFrac to SEAICE_saltFrac & SIsal0 to SEAICE_salt0;
310      - remove old parameters ( SEAICE_freeze, SEAICEturbFluxFormula, SEAICE_gamma_t,
311         SEAICE_gamma_t_frz, SEAICE_availHeatTaper & SEAICE_availHeatFracFrz)
312        from SEAICE_PARMS.h ; still need to fix seaice_cost_sst.F (broken when
313        SEAICE_freeze got retired) but already better than previously with
314        SEAICE_freeze=123456.7 deg.C;
315      - move setting of facOpenGrow/Melt from SEAICE_INIT_FIXED to SEAICE_READPARMS
316        (safer multi-threaded setting); always set SEAICEuseEVP;
317      - setting of ocean-ice turb. flux coeff: moved from SEAICE_CHECK to
318        SEAICE_READPARMS & SEAICE_INIT_FIXED (this fixes wrong summary report);
319        stop if multiple specifications for the same coeff; make sure default
320        SEAICE_mcPheePiston is compatible with drF(1) & deltaT.
321    o pkg/obcs:
322      - allow to switch to upwind 1rst order advection scheme for the advective
323        flux computation at the open-boundary; disabled for adjoint built.
324    o pkg/ptracers:
325      - rename PTRACERS_RESTART.h -> PTRACERS_START.h
326      - rename ptracers_fields_blocking_exchanges.F -> ptracers_fields_blocking_exch.F
327      - add parameter to decide when to start a tracer; use internal flag to
328        know which tracer to step-forward; switch this internal flag at the top
329        of forward_step.F (new S/R PTRACERS_SWITCH_ONOFF); for now, not enabled
330        for adjoint built.
331    o pkg/seaice:
332      - add SEAICE_SIZE.h anywhere in the code where SEAICE.h is included ;
333      - move MULTDIM declaration and setting from SEAICE.h to SEAICE_SIZE.h ;
334      - keep experiment offline_exf_seaice truly single category (set MULTDIM=1).
335    o pkg/ecco:
336      - fix writing of output file DiagnosCost_ClimSalt/Theta
337        and DiagnosCost_DriftSalt/Theta (if multi-tiles per proc).
338    o pkg/seaice:
339      - add missing initialisation of COR_ICE array in dynsolver.F
340      - merging SEAICE_MULTICATEGORY define and undef cases. Now the same code is
341        compiled either way, and is tested in all exps (multidim was only tested
342        in lab_sea ad before).
343      - cosmetic change to prepare for future addition of ITD. no change to results.
344        no defaults change.
345      - added run time param SEAICE_multDim (7 for SEAICE_MULTICATEGORY, 1 otherwise).
346      - by lack of adequate verification experiments, I further used custom versions
347        of global_ocean.cs32x15 to test multicat or not, with pickup or not. All
348        should be correct.
349      - avoid recomputations in ad.
350    o array initialisation in adjoint mode:
351      1) pkg/mom_common/mom_calc_ke.F:
352        add full array initialisation of KE inside mom_calc_ke.F (ALLOW_AUTODIFF_TAMC):
353        The S/R which calls MOM_CALC_KE initialises KE but in some recomputation
354        part this initialisation is gone, resulting in Floating Point Exception
355        (caught by open64 compiler with debug option).
356      2) model/src/convective_weights.F
357        set output convectCount over the full array range (instead of doing
358        an update): this fix a similar issue when called within recomputation (adjoint)
359        which could by-pass the initialisation (normally done in the caller S/R).
360    o pkg/seaice:
361      - final version of turbulent flux params, as agreed at MIT ice meet:
362           SEAICE_mcPheePiston (default is ~ 0.000875)
363           SEAICE_mcPheeTaper (default is 0.)
364           SEAICE_frazilFrac (defualt is 1.)
365           SEAICE_mcPheeStepFunc (default is false)
366      - changes results at trunction error level
367      - ifdef SEAICE_EXTERNAL_FLUXES, disallow SEAICE_waterAlbedo
368    o added pkg/frazil:
369      - see frazil_description.tex for details
370      - verification experiment is global_with_exf/input.yearly; changes output.yearly.txt
371    o pkg/shelfice/shelfice_thermodynamics.F
372      - fix exponents for velocity dependent exchange coefficients: change
373        from 2/3(=0) to 0.66666666666666667
374      - move computation of velocity dependent exchange coefficients into
375        separate loop, so that it applies to both thermodynamics
376      - move some divisions by constants out of loops
377    
378    checkpoint63j (2012/02/16)
379    o pkg/seaice:
380      - overhaul of seaice_summary.F after feb 2012 clean-up of seaice_growth.F etc.
381      - SItracer:  added run time params, and allow coupling to ocn salinity.
382    o pkg/seaice: remove (almost) all divisions by constants within loops
383      in seaice_growth.F and seaice_solve4temp.F, this changes (only) the cg2d
384      results of global_ocean.cs32x15.seaice from 16 to 11 digits (but only
385      those, caused by 1/QI -> recip_QI) -> update output.seaice.txt,
386      output_adm.seaice_dynmix.txt and also lab_sea: output_adm.evp.txt
387    o pkg/seaice :
388      - simplify McPhee tapering, and allow to use it with SEAICEturbFluxFormula
389        = 1 or 2, using newly added run time parameter SEAICE_availHeatTaper.
390      - fix d_AREAbyATM, d_AREAbyOCN, d_AREAbyICE diags I broke in r1.148.
391      - add permanent SItflux diag that corresponds to TFLUX but includes
392        ice+snow. Hence SItflux-TFLUX should match the ice+snow heat budget.
393      - allow activation/testing of a fix for suspected missing term in
394        ocn-ice heat budget (to be confirmed). To test this, you want to
395        undef SEAICE_DISABLE_HEATCONSFIX, and then set the run time param
396        SEAICEheatConsFix to .TRUE. that also allows the 'SIaaflux' diagnostic.
397      - no change in results, fwd or ad.
398    o global_ocean.cs32x15/results: 3 changes following from the pkg/seaice commit below:
399      - switch to variable freezing point.
400           Results change : cg2d -> 1 digits; ad -> 3-6-6 digits.
401      - bug fix : the sublimation term that was missing is now activated.
402           Results change : cg2d -> 2 digits; ad -> 8-6-6 digits.
403      - bug fix : flooding sign term for SIsal0.NE.0.
404           Result change : cg2d -> 8 digits; ad -> 11-12-9 digits.
405    o pkg/seaice:
406      - unified freezing point treatment : the old SEAICE_VARIABLE_FREEZING_POINT
407        is now the default, and the old default constant freezing point is recovered
408        with SEAICE_tempFrz0    = -1.96,
409             SEAICE_dTempFrz_dS = 0.,
410      - retire SEAICE_freeze (= the old way of specifycing the constant freezing point)
411      - remove ALLOW_SEAICE_FLOODING brackets; run time switch is already there.
412      - bug fix (thanks to M. Losch) : the sublimation term that was missing is now
413        activated. To reproduce old results with this bug define SEAICE_DISABLE_SUBLIM.
414      - bug fix (silly me) : flooding sign term (seaice_growth.F r 1.149line 1211)
415        was wrong for SIsal0.NE.0. Changes cs32x15 results (see above item for detail).
416      - bug fix (thanks to O. Jahn) : area loss for melting  got messed up in
417        seaice_growth r149 for legacy branch (no results change).
418      - introduce SEAICE_CAP_SUBLIM : caps sublimation heat flux in solve4temp (code
419        from I. Fenty).
420      - results did not change except for global_ocean.cs32x15, mostly due to the
421        switch to variable freezing point (see above item for detail).
422    o pkg/thsice:
423      - fix and simplify interface to salt_plume pkg ; diagnose directly amount of
424        seawater freezing in thsice_calc_thickn (not used).
425    o pkg/seaice: turbulent flux term specification via run time params.
426      - replace CPP switches with run time switches to facilitate testing
427      - retired CPPs : MCPHEE_OCEAN_ICE_HEAT_FLUX,
428                       GRADIENT_MIXED_LAYER_TURBULENCE_FACTOR
429      - added runtime parameter : SEAICEturbFluxFormula
430      - move Mcphee constants to SEAICE_PARAMS.h
431      - seaice_readparms.F : read turbulent flux term params (SEAICEturbFluxFormula;
432                 SEAICE_availHeatFrac/Frz, or SEAICE_gamma_t/_frz if apply);
433                 remove seaice_summary call (moved to seaice_init_fixed)
434      - seaice_init_fixed.F : set SEAICE_availHeatFrac/Frz depending on
435        SEAICEturbFluxFormula, and seaice_summary call (moved from seaice_readparms)
436      - seaice_summary.F : add missing report of read turbulent flux term set up
437                           and SITRACER.
438      - seaice_check.F : check range; inform and stop if retired CPPs are used
439                         (incl. SEAICE_AGE).
440      - seaice_growth.F : unified use of SEAICE_availHeatFrac/Frz, without
441             CPP switch, same computation as before for the different options.
442      - change results at the truncation level.
443    o pkg/seaice:
444      - remove un-used parameters LAD & MAX_TICE ; add new run-time parameters:
445        useMaykutSatVapPoly (default=F), postSolvTempIter (default=2) and
446        SEAICE_wetAlbTemp (default=-1e-3). Remove option SEAICE_SOLVE4TEMP_LEGACY.
447      - update verification/*/input*/data.seaice:
448        to reproduce previous results with former #defined SEAICE_SOLVE4TEMP_LEGACY
449        code, set useMaykutSatVapPoly=T & postSolvTempIter=0 ;
450        and to reproduce previous results with former non-SOLVE4TEMP_LEGACY code,
451        set SEAICE_wetAlbTemp=0 & SEAICE_snowThick=0.
452    o pkg/seaice/seaice_solve4temp.F (SOLVE4TEMP_LEGACY):
453      - remove LEGACY code for solving for tsurf (A1,A2,A3) but maintain the same
454        algorithm (same choice: useMaykutPolySatVap=T, postSolvTempIter=0);
455        difference in results only due to machine truncation.
456      - remove MAX_TICE (tsurf is always =< TMELT anyway); keep MIN_TICE if using
457        MaykutPolySatVap; keep MIN_LWDOWN.
458      - adapt SEAICE_MODIFY_GROWTH_ADJ code (untested) to non-legacy formulation.
459      - update output of verification exp. lab_sea (4 fwd: 11 cg2d digits except hb87,
460        + 3 AD: 6 digits except evp) and offline_exf_seaice.seaice (12 digits).
461    o pkg/salt_plume:
462      - isolate saltPlumeFlux array exch into a specific S/R called from
463        do_oceanic_phys.F
464      - add interface to pkg/salt_plume (filling of saltPlumeFlux) in pkg/thsice.
465    o verification:
466      - move untested set-up to MITgcm_contrib/verification_other.
467    o pkg/seaice:
468      - retire old way of SEAICE_AGE. Now replaced with ALLOW_SITRACER.
469    o pkg/seaice:
470      - seaice_solve4temp.F (keeping results unchanged):
471        * add 2 future run-time params to select which saturation vapor pressure
472          formula is used and how post-iteration fluxes are set.
473          Temporary set these 2 params according to option SOLVE4TEMP_LEGACY;
474        * New piece of code (not used) to update surf. atmos. heat flux F_ia using
475          the linearized expression to stay consistent with tsurf finding.
476      - seaice_freedrift.F avoid floating exception in sqrt(y) since y=sqrt(x*x)-x
477        can be < 0.
478    o pkg/seaice/seaice_solve4temp.F (SOLVE4TEMP_LEGACY undef):
479      - remove from F_ia (and from it's derivative dFiDTs1) the contribution of
480        conductive heat flux F_c , and add it explicitly when updating tsurf as
481        solution of: Fc = Fia + d/dT(Fia - Fc) *delta.tsurf
482        so that now F_ia has a consistent meaning through the entire routine.
483        This causes differences at truncation level: update output of fwd exp.
484        global_ocean.cs32x15.seaice.
485    o pkg/seaice:
486      - lots of editing/cleaning in seaice_solve4temp.F + better documentation
487        of arrays, sign/direction of fluxes; no effect on results.
488      - replace hard coded 273.16 (=previous value of celsius2K) by celsius2K
489        in seaice_budget_ocean.F & seaice_solve4temp.F (SOLVE4TEMP_LEGACY part);
490        note: this should have been done before changing celsius2K default.
491      - to keep results unchanged, add back old value of celsius2K in verification
492        exp. input*/data : lab_sea (AD), offline_exf_seaice (fwd+AD) & seaice_obcs
493      - replace hard coded seawater freezing temp in seaice_solve4temp.F (part
494        SOLVE4TEMP_LEGACY) of 271.20 (=previous value of celsius2K + default
495        value of SEAICE_freeze) by celsius2K+SEAICE_freeze so that seawater
496        freezing temp is consistent with value in seaice_growth.F ; this causes
497        differences at machine truncation level: update lab_sea AD output (3/4).
498    o pkg/seaice:
499      - mask (in exf_init_fixed.F) atemp,aqh,evap,precip,runoff,lwflx,areamask
500        and climsst/sss even when using seaice (to prevent calculation that might
501        use SST on land); does not affect any verification exp.
502      - apply mask to taux,tauy (in seaice_get_dynforcing.F); update output
503        of lab_sea.fd & lab_sea.hb87 and global_ocean.cs32x15.seaice_dynmix.
504    o pkg/seaice/seaice_growth.F: add mask to avoid non-zero ice thickness
505      over land (non-legacy code)
506    o vectorize salt_plume package:
507      - add extra code to salt_plume_frac and salt_plume_tendency_apply_s
508      - this code computes plumebk everywhere (also over land), thus requires
509        code to avoid divisions by zero and catch the case of kLev=Nr.
510      - efficiency of salt_plume_frac is still sub-optimal
511    o tools (genmake2):
512      - fix makefile NAME specification (option: -makefile NAME) by adding
513        "-f $MAKEFILE" in few places where it was missing including makedepend
514        command (contribution from Paul).
515    
516    checkpoint63i (2012/01/24)
517    o model/src:
518      - add factorized versions of some EOS code to find_rho.F,
519        define USE_FACTORIZED_EOS to turn it on (default for TARGET_NEC_SX)
520    o model/src:
521      - add celsius2K to namelist PARM01; remove unused recip_rhoNil from PARAMS.h;
522      - change default celsius2K from 273.16 to 273.15
523      - to keep results unchanged, add back old value of celsius2K in verification
524        exp. input*/data : aim.5l_cs, 1D_ocean_ice_column, lab_sea (fwd),
525         global_ocean.cs32x15(seaice) & cpl_aim+ocn(input_atm).
526    o model/src: add a little initialisation trick to find_rho.F and find_alpha.F
527      to make TAF generate vectorizable code
528    o pkg/seaice/seaice_evp.F: add code (copied from CICE) that avoids underflows.
529       Turn on by defining SEAICE_EVP_ELIMINATE_UNDERFLOWS. Most compilers
530       have flags that do this more efficiently.
531    o pkg/diagnostics/diagstats_calc.F
532      - for TARGET_NEC_SX fix the treatment of the scaling factor tmpFac=scaleFact
533    o pkg/obcs (with exch2):
534      - derive OB indices in overlap region from OB-InsideMask (in obcs_init_fixed.F)
535        and remove code (in obcs_readparms.F) which was based on EXCH of indices
536        (through buffer) and did not account for exch2 (e.g., CS-grid) topology.
537    o pkg/exf and seaice exp:
538      - change offline_exf_seaice.seaicetd test exp. to use default DIFF1 value (=0)
539        so that switching off area & heff advection flags does not affect results.
540      - change default EXF_LWDOWN_WITH_EMISSIVITY to #define in EXF_OPTIONS.h
541      - keep exp. seaice_obcs & 1D_ocean_ice_column(ad) unchanged (using #undef
542        EXF_LWDOWN_WITH_EMISSIVITY) and, using pkg/exf default emissivities, update
543        results of verification experiments: 1D_ocean_ice_column(fwd),
544        global_ocean.cs32x15.seaice(fwd+ad) & seaice_dynmix(ad), lab_sea (all 8)
545        and offline_exf_seaice (all 4).
546    o pkg/seaice:
547      - remove array YNEG, RIVER, TMIX (replaced by local var) from common block;
548        remove also areaNm1 & hEffNm1 when SEAICE_GROWTH_LEGACY is undef.
549      - fix bug: areaNm1 & hEffNm1 are needed in seaice_growth (SEAICE_GROWTH_LEGACY)
550        but were not filled when resp. SEAICEadvArea=F & SEAICEadvHeff=F and
551        not multi-dim advection;
552      - fix seaice_growth.F to compile with both SEAICE_GROWTH_LEGACY and
553        SHORTWAVE_HEATING #undef.
554    o optim: make Makefile more robust (?)
555    o pkg/obcs:
556      * fix treatment of obcs_read_pickup for TAF
557    o pkg/shelfice:
558      * add missing initialisation of num_shifwflx
559      * new adjoint verification exp. for isomip
560      * change Prandtl and Schmidt numbers from generic formulations
561        (in terms of model diffus. and visc.) to separate runtime
562        parameters, with Holland and Jenkins (1999) default values.
563    o pkg/exf (interpolation):
564      - extended input field (2 rows) near the N & S poles:
565        * fill in with the symetric value (when even Nb of data in longitude)
566        * add average value at the poles only for scalar quantities ; for vector
567          component interpolation, skip the averaging and keep duplicated values,
568          unless the 2 components have same location (uvInterp=T) in which case
569          interpolate the 2 components together using S/R EXF_INTERP_UV.
570      - new S/R EXF_INTERP_UV to interpolate the 2 components of a vector field
571        together: this allows to account properly for local orientation when
572        averaging at N & S pole.
573      - add CPP option EXF_USE_OLD_INTERP_POLE to recover old results regarding
574        exf-interpolation near N & S poles. Undef by default.
575      - add debug check/print on 1rst iter if debugLevel >=2.
576    o pkg/exf:
577      - change masking flags definition (no longer "parameter"), put them in
578        common block and set them in S/R EXF_INIT_FIXED.
579      - change recognized masking flag from s,u,v to c,w,s since the mask
580        to use (maskC,W,S) depends on position on model grid and has little to
581        do with scalar/vector difference; fix masking if using P-coordinates.
582      - fix masking of wind-stress (was wrong if interpolated or read on A-grid)
583        and update results of exp. global_with_exf (x2).
584      - fix setting of zenith-angle table when SHORTWAVE_HEATING is undef.
585    o pkg/obcs
586      - S/R obcs_calc_stevens: fix a small bug (gammat -> gammas where appropriate)
587    o pkg/exf (interpolation):
588      - assume periodicity in X only if input field cover full longitude range.
589      - improve search for lat. index (supposed to be faster, in ~log2(ny) steps,
590        and should vectorise).
591      - fix input lat of the 2 added row (in case we provide N.pole data).
592    
593    checkpoint63h (2011/12/30)
594    o pkg/seaice:
595      - change declaration of UVM from _RL to _RS in order to get B-grid
596        uIce,vIce monitor when _RS = real*4
597    o pkg/offline:
598      - new S/R OFFLINE_RESET_PARMS for resetting main-model params (switch off flags);
599      - compute vertical velocity if not read from file (switch on exactConserv
600        & staggerTimeStep);
601      - fix output of ptracer monitor iter & time for default PTRACERS_monitorFreq.
602    o verification:
603      - update grid-files (in tutorial_held_suarez_cs/input and fizhi-cs-32x32x40/input)
604        with grid-angle generated using "utils/matlab/cs_grid/cubeCalcAngle.m":
605        fix Pb in yG definition @ 2 missing corners (previously yG was averaged);
606      - update output of exp. global_ocean.cs32x15.viscA4 after changing
607        grid-file angles (used here for coriolis-3d);
608      - remove (or gzip) few files not needed to run fizhi-cs experiments.
609    o pkg/exf (vector interpolation):
610      - rotate vector component toward local grid-axis orientation using grid-angles
611        (stored in GRID.h) instead of locally computed rotation angle; keep old code
612        available with exf option EXF_USE_OLD_VEC_ROTATION (undef by default).
613    o pkg/seaice:
614      - allow to compile with exf options ALLOW_ATM_TEMP or ALLOW_DOWNWARD_RADIATION
615        undefined. Fix and remove the stop when ALLOW_RUNOFF is undefined.
616    o pkg/PKG_OPTIONS.h files:
617      - move #include "CPP_OPTIONS.h" just after #include "PACKAGES_CONFIG.h",
618        outside of the #ifdef ALLOW_THISPKG / #endif block.
619      - update verification/*/code/PKG_OPTIONS.h files.
620    o add a verification experiment (offline_exf_seaice/input.seaice) that test
621      the B-grid LSOR solver
622    o pkg/seaice: sort out emissivity and long wave radiation step 2:
623      - add emissivity for snow and ice as new run-time parameters
624        (unfortunately) that default to the corresponding exf values; this
625        changes results in most verification experiments so that for backward
626        compatibility these parameter have to be set explicitly to inconsistent
627        values (ugly);
628      - the exf-flag EXF_LWDOWN_WITH_EMISSIVITY then gets rid off the hard-wired
629        emissivities of 0.97 associated with lwdownloc in S/R seaice_solve4temp
630        until we agree how to handle this bug properly
631    o pkg/exf (interpolation):
632      - add a set of run-time param ({inputfield}_interpMethod), one for
633        each interpolated input field, to select the interpolation method
634        with a value of zero switching off the interpolation;
635      - print interpolation parameters to standard output;
636      - refine exf_check.F accordingly ; stop if USE_NO_INTERP_RUNOFF is defined
637        (to use instead runoff_interpMethod=0 in data.exf).
638      - simplify default setting of interpolation parameters (for all fields,
639        set position to match model grid cell-center position, leading to trivial
640        interpolation in case of regular Lat-Lon grid) and fix for the case of
641        non-uniform delY.
642    o pkg/exf/exf_radiation.F: add the factor ocean_emissivity to lwdown, for
643       within #ifdef EXF_LWDOWN_WITH_EMISSIVITY/#endif. Unless ocean_emissivity=1.
644       this factor is absolutely required, because the lw exitance (= out-going
645       long wave radiation) is emissivity*stefanBoltzmann*T^4 + rho*lwdown,
646       where the reflectivity rho = 1-emissivity for conservation reasons. Once
647       this is established, we can remove the CPP-Flag (if we want to).
648    o pkg/seaice:
649      - qualify a stop statement in S/R seaice_check: EXF_READ_EVAP and
650        ALLOW_BULKFORMULAE are only required if SEAICE_EXTERNAL_FLUXES is defined
651      - sort out emissivity and long wave radiation, step 1: make SEAICE_emissivity
652        what the name implies (and not emissivity*BoltzmannConstant), this means
653        the old default value of 5.5e-8 now means
654        5.5e-8/5.670e-8 = 0.97001763668430343479 as ocean_emissivity in
655        S/R exf_readparms
656      - FV-discretization of the B-grid LSOR solver, turn on with
657        SEAICE_LSRBNEW. This new solver also involves a slight re-organization
658        of the calling routine dynsolver, so that B and C-grid code look a
659        little more alike.
660      - fix index bugs in ostres.F (B-grid code)
661    o pkg/seaice/seaice_ocean_budget.F: change (unused) code to make it look better
662    o pkg/seaice/seaice_readparms.F: make ocean_emissivity*stefanBoltzmann the
663      default for SEAICE_emissivity, if useEXF; requires setting a wrong
664      parameter value in global_ocean.cs32x15/input.seaice/data.seaice for
665      backward compatiblity
666    o model/src: use sigmaR in calc_ivdc
667    
668    checkpoint63g (2011/12/16)
669    o pkg/seaice/seaice_growth.F:
670      fix heat conservation of the coupled ocean-seaice system.
671      when SEAICE_HEAT_CONSERV_FIX is defined, the mismatch of
672      solid vs liquid water treatment is resolved via QNET.
673    o pkg/seaice/seaice_growth.F:
674      add missing term for sublimation in saltFlux, which was breaking conservation.
675    o pkg/seaice/seaice_model.F:
676      Remove this patholigical case treatment in evolution branch,
677      where it is un-necessary and breaks conservation.
678      Update global_ocean.cs32x15/results accordingly for
679      output.seaice.txt output_adm.seaice.txt and output_adm.seaice_dynmix.txt
680    o model/src:
681      useRealFreshWaterFlux: remove masking of EmPmP (using maskInC) in
682      external_forcing_surf.F and apply mask directly in S/R SOLVE_FOR_PRESSURE.
683    o pkg/obcs:
684      modify Stevens boundary conditions so that S/R obcs_calc_stevens computes
685      tendency for temperature and salinity that is then applied to update
686      theta and salt in S/R obcs_apply_ts; this requires proper masking of all
687      horizontal advection and diffusion contributions on the boundary (in
688      S/Rs gad_advection, gad_calc_rhs, gmredi_rtransport, gmredi_calc_diff), and
689      removing the mask in S/R timestep_tracer. The advantage of this approach is
690      that the updated tracer values include contributions from the surface
691      forcing and vertical diffusion.
692      This modification changes exp4.stevens because of vertical diffusion.
693    o model/src:
694      change non-curvilinear grid setting to also work with exch2 + blank tiles:
695      - move delX,delY to new header file (SET_GRID.h) and adjust length to 1rst
696        face dimensions.
697      - new S/R INI_LOCAL_GRID to define model tile-local grid (using same units
698        as delX,delY) and called from S/R INI_CARTESIAN_GRID, INI_CYLINDER_GRID
699        and INI_SPHERICAL_POLAR_GRID.
700      change test-experiment global_ocean.90x40x15:
701      - split the domain in many more tiles (9x4 tiles of 10x10 each);
702      - switch to exch2 and remove 1 blank-tile (but only for MPI test).
703      - update results of both test (std & dwnslp).
704    o pkg/diagnostics/diagstat_calc.F: fix problem with non-initialised halos in
705       tmp-fields for TARGET_NEC_SX at the cost of extra loops and less vectorisation
706    o model/src:
707      - take sigma-coords related code out of update_etah.F into new S/R UPDATE_ETAWS
708        and fix initialisation when using sigma-coords.
709    o model/src:
710     - improve Gael's changes from Jan 14, 2011 "addition of an 'update' of hfacc etc.
711       to their current value at the beginning of forward_step.F": add a new run-time
712       switch "doResetHFactors" (default=false) and use it to do (or not) the resetting.
713     - set doResetHFactors=T in the following test exp:
714        global_ocean.90x40x15/input (rStar) & input.dwnslp (linFS),
715        global_ocean.cs32x15/input.seaice (rStar), hs94.cs-32x32x5/input.impIGW (linFS)
716        and tutorial_global_oce_in_p (nonLinFS in p)
717    o pkg/ecco
718      - added IES cost term
719    o verification/advect_xz
720      - scale down the depth by 1/100 (from 200 km to just 2.km)
721      - add secondary test using divergent flow, r-star and implicit vertical advection.
722      - add note (check_conserve_TS.txt) and matlab script to check global
723        conservation of T & S with NonLin-FreeSurf and Adams-Bashforth.
724    o pkg/rbcs:
725      - add missing relaxUFile & relaxVFile in namelist (in rbcs_readparms.F).
726    o pkg/obcs (Stevens BCs):
727      - fix various problems in the phase speed computations of the Stevens
728        boundary conditions:
729        - sign error for western and southern boundaries,
730        - time tendencies were underestimated by factor of dTracerLev and some just
731          zero (for multidim advection schemes) -> now estimate time tendencies
732          from difference between previous (n) time level and the one before (n-1);
733          this requires storing a field per tracer per boundary, also in the pickup
734          files.
735        - replace deltaTmom in cflMer/Zon computation with dTracerLev
736        - set default phase velocity to cflMer/Zon
737      - update verification experiment exp4.stevens
738    o pkg/generic_advdiff (implicit_r):
739      - fix implicit vertical advection conservation with AB and/or NonLin-FreeSurf
740        (remove Tr*d/dz(w) in gad_implicit_r.F and add it in gad_calc_rhs.F);
741      - fix implicit vertical diffusion or advection with NonLin FreeSurf
742        (was using current recip_hFacC instead of future recip_hFacC): set future
743        recip_hFac in thermodynamics.F and pass & use it in all vertical implicit
744        solver S/R ;
745      - fill diagnostics of vertical advective fluxes (computed from tendency)
746        when using implicit vert. advection;
747      - update output of exp that uses NonLin-FreeSurf & implicit vertical diffusion:
748         global_ocean.90x40x15 (fwd+AD), global_ocean.cs32x15 (4 fwd +4 AD),
749         tutorial_global_oce_in_p (fwd), tutorial_tracer_adjsens (AD)
750         and cpl_aim+ocn (used in ocean); to be fixed: bottom_ctrl_5x5.
751    o pkg/diagnostics:
752      - add diags for T & S tendency which goes through Adams-Bashforth.
753    
754    checkpoint63f (2011/11/30)
755    o pkg/obcs/obcs_calc_stevens.F:
756      - join some loops to reduce number of if-statements
757      - fix a bug in code for northern and southern boundaries.
758    o pkg/seaice/seaice_init_varia.F
759      - undo resetting UVM=0 that has slipped in unnoticed in r1.49 and
760        caused zero ice-velocities for the B-grid code
761    o pkg/seaice/seaice_init_fixed.F
762      - fix a bug in the initialisation of the second metric terms
763        k2AtC and k2AtZ: k2AtC was set to the value of k2AtZ and k2AtZ was 0.
764      - this affects all seaice configurations with useCurviLinearGrid = .true.
765        and SEAICEuseDynamics = .true. (default) and SEAICEuseMetricTerms
766        = .true. (default)
767      - the only verification experiment affected is global_ocean.cs32x15:
768        icedyn, seaice, and seaice_dynmix (AD)
769    o pkg/thsice/thsice_diagnostics_state.F
770      - only for TARGET_NEC_SX: initialise all of tmpFld, so that overlap does
771        not contain garbage that can lead to surprises in diagstats_calc.F
772    o model/src:
773      - move bi,bj loops inside INTEGR_CONTINUITY ;
774      - call INTEGR_CONTINUITY directly from forward_step.F
775        (previously called from momentum_correction_step.F)
776      - call UPDATE_ETAH from integr_continuity.F and update initialise_varia.F,
777        forward_step.F and pkg/ecco/the_main_loop.F
778    o model/src/do_oceanic_phys.F:
779      - reset addMass to zero only if useICEFRONT ;
780      - separated k-loop for rhoInSitu calculation ;
781      - add 2 diagnostics for wVel*delta^k(Rho) at constant pressure (= WdRHO_P)
782        and at constant T,S (= WdRHOdP);
783      NOTE: change diagnostics WRHOMASS : this is now simply the Vertical transport
784        of In-Situ Density (Anomaly) (=wVel*rho^bar-k) (previously was Vertical
785        transport of locally-referenced potential density);
786        to recover old diag: (WRHOMASS)_old = (WRHOMASS)_new -1/2 * (WdRHOdP)
787    o gluemnc:
788      - replace ncrcat with ncks when adding variables to *.glob.nc
789      - change the way variables without record dimensions are handled so that
790        files that have variables with and without record variables can be glued:
791        add a record dimension with a new unique name to be able to differentiate
792        between variable with and without a-prior record dimensions. Remove
793        this record dimension before adding the variable to the *.glob.nc file.
794        This procedure automatically works also for grid.*.nc files that do not
795        have any record dimension.
796    o verification/cpl_aim+ocn:
797      - generate new reference output on baudelaire (gfortran, mpich2) (previously
798        from old aces-grid cluster, ao + ifort) and update 'run_cpl_test' script.
799    o pkg/obcs/obcs_calc_stevens.F:
800      - add code for northern and southern boundaries.
801      - reorder some loops to save some operations and so that drFBar can be scalar
802    o model/src:
803      - re-arrange extrapolation calculation in Adams-Bashforth S/R (affects machine
804        truncation) and add diagnostics for Adams-Bashforth tendency increment.
805      - update test-exp. AD output:
806        1D_ocean_ice_column, bottom_ctrl_5x5, lab_sea.noseaicedyn, obcs_ctrl;
807      and FWD output: exp4 (x3), fizhi-cs-32x32x40, fizhi-cs-aqualev20,
808        front_relax (x3), global_ocean.90x40x15 (x2), global_ocean.cs32x15 (x5),
809        global_ocean_ebm, ideal_2D_oce, internal_wave, isomip (x3), lab_sea (x4),
810        matrix_example, MLAdjust (x5), natl_box (x2), tutorial_advection_in_gyre,
811        tutorial_global_oce_in_p, tutorial_global_oce_latlon and
812        tutorial_plume_on_slope.
813    o pkg/diagnostics/diagstats_calc.F: add special code for TARGET_NEC_SX
814      that vectorises. This code uses 3 extra 2D fields, F90 array assignments
815      and F90 intrinsic routines SUM, MINVAL, MAXVAL, but since TARGET_NEC_SX
816      does not even come with an F77 compiler anymore, this should not be
817      a limitation
818    
819    checkpoint63e (2011/11/06)
820    o pkg/seaice adjoint of LSR:
821      - substantially rework STORE dirs.
822      - add new flag SEAICE_LSR_ADJOINT_ITER and parameter SOLV_MAX_FIXED
823        this flag will do SOLV_MAX_ITERS but only store SOLV_MAX_FIXED fields
824        and only perform SOLV_MAX_FIXED adjoint iters.
825        If flag SEAICE_LSR_ADJOINT_ITER is undef-ined, the store in the iteration
826        always goes to same record, meaning that the last forward field will be
827        the one used in the adjoint - an approximation.
828      - now produces non-zero LSR-related gradients, and acceptable gradients for
829        An's zonal (x-z) test case (to be checked in)
830      - lab_sea: produces acceptable gradients for lab_sea with forward/backward LSR
831        (but these are screwed up by the thermodynamics in the first place);
832        reduce from 4 to 3 timesteps to avoid t.d. issue as temporary solution;
833        output_adm.txt also reflects changes to seaice_lsr
834      - global_ocean.cs32x15:
835        * the "default" input_ad.seaice has been re-defined to always exclude dynamics
836          (output_adm.seaice.txt was updated)
837        * new input_ad.seaice_dynmix tests a forward LSR / backward free-drift
838          (output_adm.seaice_dynmix.txt)
839    o test-exp. exp4+stevens:
840      - switch off pTracers and nonHydrostatic (restart problems with NH); update output
841    o pkg/seaice (lsr solver):
842      - put coriolis term into FORCEX,Y (as in seaice_evp.F; previously in rhsU,V only);
843        update output (change truncation) of FWD test exp lab_sea & global_ocean.cs32x15
844      - fix SEAICEuseFREEDRIFT for new OBCS version (ndef OBCS_UVICE_OLD)
845      - new parameter "LSR_mixIniGuess" allows (if=2,4) to mix free-drift solution
846        into initial guess for linearised solver; use weight ~ (1/err)^2,4.
847      - compute (with new S/R) and print initial (+ free-driff sol. if available)
848        and final residual of linearised system.
849    o pkg/pp81: add diagnostics for vertical eddy viscosity and diffusivity
850      (requires new subroutines pp81_init_fixed.F/pp81_diagnostics_init.F)
851    o pkg/obcs: Stevens BCs (still only for east and west)
852      - fix Stevens BCs by using intermediate velocities of previous
853        time step as "baroclinic" contribution rather velocity of one grid cell
854        inside the boundaries; more consistent but makes the entire treatment
855        more complicated, requires new pickup files and two new S/Rs:
856        obcs_copy_uv_n and obcs_save_uv_n
857        keep old version with flag OBCS_STEVENS_USE_INTERIOR_VELOCITY
858        (undefined by default)
859      - silently move computation of some grid factors into separate loops to
860        save some recomputations
861      - add a hack for non-linear free surface
862      - add a verification experiment to exp4 that tests this code
863    o make gluemnc/xplodemnc work with (moron) non-GNU shell tools
864    
865    checkpoint63d (2011/10/25)
866    o pkg/obcs + seaice-dynamics:
867      - new implementation calls OBCS_APPLY_UVICE (in seaice_dynsolver.F) before
868        solving for uIce,vIce and prevent SEAICE_LSR or SEAICE_EVP to modify OB
869        values (consistent with an implicit method).
870      - add option OBCS_UVICE_OLD (in OBCS_OPTIONS.h, defined by default) to
871        return to older implementation (same results as before); note that none of
872        the "experimental" OBCS_SEAICE options are implemented in the new version.
873      - switch test exp. seaice_obcs to use new version (update output).
874    o pkg/seaice:
875      - add few stop (B-grid & CS-exch, B-grid & obcs, AUTODIFF & SEAICE_maskRHS)
876      - add parenthesis in Water-Ice drag calculations (evp & lsr);
877      - in seaice_lsr.F, simplify and fix AA3 setting in case sNx or sNy=1;
878        and fix case SEAICE_waterDrag=0 (but unstable if no or little seaice)
879      - update output of test exp lab_sea that uses evp or lsr (fwd+ad)
880        and global_ocean.cs32x15 (icedyn & seaice fwd+ad).
881    o pkg/layers:
882      - Include potential density as new coordinate (Thanks to David Munday)
883    o pkg/dic:
884      - Remove subroutine CALC_PCO2_APPROX_CO3 from carbon_chem.F and add
885        carbonate computation/output to CALC_PCO2_APPROX
886    o pkg/generic_advdiff
887      - make TAF generate code that vectorizes:
888        gad_dst3fl_adv_*.F, gad_u3c4_impl_r.F
889    o model/src:
890      - improve vectorization also for adjoint code of
891        solve_tridiagonal and solve_pentadiagonal. As this requires up to
892        5 new 3D-fields, this code is only turned on for the combination of
893        ALLOW_AUTODIFF_TAMC and TARGET_NEC_SX. Also remove error message
894        for singular matrix check (only for TARGET_NEC_SX).
895      - remove hard-wiring of CPP-flag ALLOW_SOLVERS_KLOOPINSIDE to
896        ALLOW_AUTODIFF. This flag now needs to be set outside of
897        solve_tri/pentadiagonal.F
898    o pkg/exf:
899      - fix previous modif in exf_readparms.F (revision 1.66: treatment of
900        optional namelist EXF_NML_OBCS).
901      - add many debug-print (to trace down where pkg/cal error msg comes from)
902    o pkg/mom_vecinv/mom_vi_hdissip.F
903      - rearrange loops so that vectorization is improved and in particular
904        the adjoint routine vectorizes. The code is a little longer now, but I
905        think easier to read.
906        Note: CPP-flag MOM_VI_ORIGINAL_VISCA4 is not tested.
907    o pkg/seaice:
908      - allow to specify initial seaice velocity from files (uIceFile,vIceFile)
909    o pkg/exch2:
910      - alternative code (without tile x tile matrix) for cumulated (global) sum;
911        used as default; keep using matrix version in adjustment.cs-32x32x1.
912    o tools/build_options:
913      - after merging some MPI and/or multi-threads specific optfiles so that
914        the modified default optfile support both built (using genmake2 -mpi
915        for the MPI built, using genmake2 -omp for OpenMP built),
916        move now obsolete optfiles to tools/build_options/unsupported/
917       (add copy of email sent to support list in doc/optfiles_changes.txt)
918    
919    checkpoint63c (2011/09/28)
920    o pkg/ebm:
921      - fix ebm_zonalmean.F for several procs in Ydir (nPy > 1); update output of
922        test exp. global_ocean_ebm (affects machine truncation, 12 digits for cg2d)
923    o pkg/seaice (SItracer pickup)
924    * Simple code for pickup of SItracer fields (#define ALLOW_SITRACER)
925      To be done:
926      - thorough testing of missing fields in S/R seaice_read_pickup
927      - thorough matching between generic tracers and specific fields used
928        (e.g. volume-weighted age, area-weighted age, salinity, ...)
929    o pkg/grdchk:
930      - all procs calculate and print finite-difference gradient (for testreport)
931      - change description output used by testreport;
932      - AD testing: also compare and report Finite-difference gradient;
933        => update all output_adm*.txt
934    o test exp. global_ocean_ebm:
935      - switch back useRealFreshWaterFlux (no problem anymore with run-off);
936        and turn on exactConserve; update (fwd) output.
937    o pkg/seaice (LSR):
938      - print to STDOUT number of solver iterations at SEAICE_monFreq interval.
939      - modify solver to deal cleanly with u/v switch at face edges (CS-grid):
940        * identical results with non-CS topology (but save up to half of EXCH calls)
941        * no much changes in cs-32 verification tests since no ice at face edges
942         (differences due to convergence criteria, since nb of iterations changed)
943        * expect some differences on lat-lon-cap grid.
944        update FWD results of global_ocean.cs32x15 test exp. (icedyn & seaice)
945    o pkg/exch2:
946      - add new CPP option to disable Cumul-Sum matrix (to save storage when using
947        many tiles); until alternative coding is added, just add a stop.
948    o pkg/kpp:
949      - move ptracer/salt correction to KPP diffusivity from calc_3d_diffusivity.F
950        to S/R KPP_CALC_DIFF_PTR (+ add tracer-index to argument list).
951    o optfiles:
952      - merged few MPI specific (*+mpi*) and multi-threads specific (*+mth) optfiles
953        into corresponding standard one, which now support different build:
954        (when using "genmake2 -mpi" for MPI built, "genmake2 -omp" for OpenMP built)
955      - add "darwin_amd64_gfortran" optfile (initially from Constantinos, tested by Gael)
956    o pkg/obcs (seaice):
957      - add missing EXCH for uIce,vIce after applying OBCS;
958      - remove S/R EXF_SWAPFFIELDS_X/Y , disable S/R EXF_SET_OBCS_X/Y by adding
959        argument = number of levels to S/R EXF_SWAPFFIELDS_XZ/YZ and S/R
960        EXF_SET_OBCS_XZ/YZ ; update obcs_exf_load.F;
961      - fix EXF_SET_OBCS_XZ/YZ for multi-threaded (assuming loaded arrays are shared)
962      - verification exp. seaice_obcs: split domain in 2 tiles ; add SIZE.h_mpi
963        and eedata.mth for MPI and mutlti-threaded testing.
964    o pkg/flt:
965      - make FLT EXCH working with multi-threads (and MPI + multi-threads);
966      - use buffer for floats IO (trajectories & profiles); size set in FLT_SIZE.h;
967      - fix pickup and trajectories + profiles output with multi-threads;
968      - add parameter to select group of fields to write along trajectory and
969        profile (default unchanged);
970      - only call PORT_RAND* function when flt_noise <> 0;
971      - add multi-threaded test for verification exp. flt_example.
972    o eesupp/src:
973      - fix S/R ALL_PROC_DIE for MPI+multi-threads.
974      - USE_OMP_THREADING: check that number of threads (from eedata) matches
975        actual number (from env.var. setting).
976    o pkg/ebm:
977      - fix multi-threading in ebm_area_t.F ; clean-up EBM.h header file.
978      - add multi-threaded test for verification exp. global_ocean_ebm
979    
980    checkpoint63b (2011/08/29)
981    o pkg/ebm:
982      - fix sign of runoff;
983      - update directly forcing fields (Qnet,EmPmR) to use standard
984        external_forcing_surf.F (remove ebm_forcing_surf.F);
985      - avoid loading forcing fields a 2nd time (1rst time from ini_forcing.F);
986      - set either tauThetaClimRelax (in data) or tauThetaZonRelax (in data.ebm)
987        and apply relaxation towards corresponding SST field (2-D map or ZonAver).
988      - update global_ocean_ebm parameters file data and update output (fwd+ad).
989    o verification/matrix_example:
990      - split domain in 8 tiles (2x4); add SIZE.h_mpi and eedata.mth for
991        MPI and mutlti-threaded testing.
992    o pkg/matrix:
993      - change name of S/R MATRIX_INIT to S/R MATRIX_INIT_VARIA ;
994      - fix for multi-tiles (add bi,bj indices to exp/impMatrixCounter);
995      - fix for multi-threaded (remove DATA statement);
996      - use standard DIFFERENT_MULTIPLE function;
997      - add MATRIX_OPTIONS.h
998    o verification/matrix_example:
999       To allow to split the domain in several tiles, change the domain size
1000        from 31x31 to 32x32 by adding 1 row (on Southern side) + 1 column (on
1001        Western side) of land points.
1002    o (*_)write_pickup:
1003      - fix few bugs in mypackage_read/write_pickup.F
1004      - in MDS_WR_METAFILES calls, replace "myTime" by a local copy into
1005        array of length 1 (was caught by compiler syntax-check).
1006    o pkg/diagnostics (velocity potential solver):
1007      - fix initialisation of main diagonal matrix (for overlap values)
1008    o tools/build_options:
1009      - towards single optfile for MPI and non-MPI built: merge few +mpi optfile
1010        into previously non MPI one (linux_am64 pgf77,open64,pathf90,ifort11)
1011      - linux_amd64_gfortran: merge +mpi_generic version into standard optfile:
1012        * move IEEE flags to DEVEL section; take IEEE flags from +mpi_generic ;
1013        * FAST case: for now, keep -O3 with ini_masks_etc.F in NOOPTFILES list;
1014        and use "-devel" testreport option for standard testing on baudelaire.
1015    o pkg/grdchk:
1016      - Assume that all gradient-check position are within the same tile
1017        corresponding to global indices (iGloTile,jGloTile) and that
1018        positions (i,j indices or nbeg) are local to this tile;
1019      - set tile local-indices and proc. number according to tile global-indices;
1020      - remove grdchkwhichproc from namelist (retired param);
1021      - send adjoint gradient to all procs so that all procs print it to STDOUT;
1022      - switch on MPI test for global_ocean.90x40x15 AD test experiment.
1023    o adding package bbl (Bottom Boundary Layer)
1024      description in MITgcm/pkg/bbl/bbl_description.tex
1025      example/test experiment in MITgcm_contrib/bbl
1026    o adjoint verifications
1027      - changed 5 experiments to multi-tiles
1028        * global_ocean.90x40x15
1029        * obcs_ctrl
1030        * offline_exf_seaice
1031        * tutorial_dic_adjoffline
1032        * tutorial_tracer_adjsens
1033        changed reference output for those that crossed tile boundaries
1034        (changed choices of gradient check positions)
1035      - with same tiling, switch on MPI test for the last 4 (add SIZE.h_mpi)
1036      - temporary bug fix in grdchk_loc.F for obcs
1037    o genmake2 & testreport
1038      - add target "obj" (just for OBJFILES files) to Makefile;
1039      - add option to specify FEXTRAFLAGS on command line.
1040    o pkg/mypackage:
1041      - remove bi,bj arguments from argument list of S/R MYPACKAGE_CALC_RHS
1042    
1043    checkpoint63a (2011/08/02)
1044    o pkg/diagnostics (velocity potential):
1045      - fix velocity-potential calculation when using OBCS: balance net inflow
1046        at each level (new S/R OBCS_DIAG_BALANCE).
1047      - fix some of the problems with OBCS in stream-function calculation.
1048    o pkg/exf/exf_readparms.F
1049      - make treatment of optional namelists (EXF_NML_04, EXF_NML_SGRUNOFF,
1050        EXF_NML_OBCS) more consistent, so that you need not have these lists
1051        in data.exf when they are not used.
1052    o optim/optim_readdata.F:
1053      - add some output about obcs variables that might help debugging
1054      - add a check about nvarlength
1055    o pkg/ctrl: once again, fix computation of endrec in s/r ctrl_init_rec
1056    o pkg/diagnostics (velocity potential):
1057      - fix mask for OBCS (still problems in stream-function with OBCS);
1058      - add specific parameter (default = main code CG2D params) for solver;
1059      - in case of poor convergence, use solution corresponding to lowest residual.
1060    o pkg/seaice/seaice_growth.F: small changes that permit vectorizable
1061      adjoint code. In general statements like tmpscal=fld(i,j) are problematic
1062      and should be avoided where possible.
1063    o model/src (rStar):
1064      - include r* effect on reference-state (PhiRef) in totPhiHyd
1065        (so that it's really the potential anomaly at the cell center);
1066        affect solution only if z* with full pressure in EOS.
1067      - test-exp global_ocean.90x40x15: reduce viscA4 (was not stable) and
1068        update output (because of z* in totPhiHyd and viscA4 changes);
1069      - keep the previous diagnostics as "PHIHYDcR" (closer to potential anomaly
1070        @ constant r) until interpolation at constant r is implemented.
1071    o pkg/diagnostics
1072      - fix RCENTER diagnostics in case cell center is not at interface middle
1073    o add code for TEOS-10 (www.teos-10.org, McDougall et al. 2011). Use
1074      this eos with eosType = 'TEOS10', in data (PARM01). This eos implies
1075      that THETA and SALT are "conservative temperature" and "absolute
1076      salinity"
1077    o pkg/ctrl
1078      - fix computation of endrec in s/r ctrl_init_rec
1079      - ctrl_pack/unpack_*: remove unused variables and some obsolete code
1080    o pkg/seaice/seaice_growth.F
1081      - fix recomputation with FENTY_AREA_EXPANSION_CONTRACTION code,
1082        remove then obsolete STORE directives
1083      - fix STORE directives for tice and tices, so that only the
1084        appropriate part of the fields are stored (and not the entire
1085        field); update global_ocean.cs32x15.seaice AD output.
1086      - cosmetic changes: adjust CPP flags and indentation for better
1087        legibilty
1088    o pkg/autodiff: add mnc-output of adBottomDragFld (code contributed by
1089      Chris Wilson)
1090    o pkg/gmredi:
1091       Add Sub-Meso Eddies parameterisation from Baylor (for now, disabled with TAF),
1092       and test it in verification exp. "front_relax.bvp" (update output.bvp.txt)
1093    
1094    checkpoint63  (2011/07/11)
1095    o pkg/exch2:
1096     - rename+move: nTiles in W2_EXCH2_PARAMS.h --> exch2_nTiles in W2_EXCH2_TOPOLOGY.h
1097     - exch2 version of Cumul-Sum routine: S/R W2_SET_MAP_CUMSUM set up the
1098       (2*nTiles)x(nTiles) Cumul-Sum matrix and Master Proc collects all tiles X,Y
1099       increments, calculates Cumul-Sum @ tile origin and sends results to each tile.
1100    o pkg/diagnostics:
1101     - deal with pairs of post-processed diags which are computed together; in
1102       particular, re-order list of diags within 1 file to save 2nd computation.
1103     - add S/R to compute velocity stream-function (called after velocity-potential
1104       calculation) from divergence free transport -> new diagnostics "PsiVEL".
1105     - add parameter to select grid-point location where PsiVEL == 0.
1106    o eesupp/src:
1107       new S/R to calculate cumulated sum on tiled array, corner grid-cell location
1108       (specific S/R needed with exch2 topology - for now, just print an error msg)
1109    o pkg/shelfice
1110     - Implement friction velocity-dependent transfer coefficients following
1111       Holland and Jenkins, JPO, 1999
1112       Original code by M. Losch with small modifs.
1113       Enable with CPP option SHI_ALLOW_GAMMAFRICT
1114       and runtime flag SHELFICEuseGammaFrict
1115    o verification lab_sea & global_ocean.cs32x15:
1116     - use tools/xmakedepend (instead of cyrus_makedepend, in genmake_local):
1117       does not miss some dependencies (but is slower) and also works with many files
1118       (default makedepend limitation for AD built).
1119     - use cyrus_makedepend in adjustment.128x64x1 (so that it still tested).
1120    o pkg/diagnostics:
1121     - add run-time parameter "useMissingValue" (def=False) to fill land-point
1122        (i.e., where mask=0) with MissingValue ; used only in MNC output file.
1123       This replaces CPP-option DIAGNOSTICS_MISSING_VALUE.
1124     - Extend the use of "missing_value" setting from data.diagnostics for the case
1125       of counter-diagnostics (where fraction-weight is zero). This applies both to
1126       MNC and MDS output files.
1127    o pkg/seaice/seaice_growth.F:
1128      - add 'a priori' cap of latent heat flux based on actual mass considerations
1129        when SEAICE_ADD_SUBLIMATION_TO_FWBUDGET is used in conjunction with the
1130        non-legacy seaice_solve4temp.
1131      - add diagnostic of the residual sublimation freshwater flux (the freshwater
1132        flux taken from the ocean if the total actual latent heat fluxes exceed
1133        the maximum)
1134      - remove the CPP switch around the *_FWbySublim unit change and move diagnostic
1135       fill for SIatmQnt, SIfwSubl, SIatmFW to the end of seaice_growth.F.
1136      - add diagnostic of the actual sublimation freshwater flux (that is 0. ifndef
1137       SEAICE_ADD_SUBLIMATION_TO_FWBUDGET) and of the latent heat flux (evap+sublim).
1138      - bug fix : frWtrAtm needs a_FWbySublim ifdef SEAICE_ADD_SUBLIMATION_TO_FWBUDGET.
1139      - bug fix : missing part to Martin's r_FWbySublim pathological case fix.
1140    o verification 1D_ocean_ice_column:
1141       made model domain truly 1x1x23 instead of 5x5x23 with only center cell (3,3,:) wet
1142       update results
1143    o pkg/diagnostics:
1144     - Implement setting of "Post-Processed" diagnostics (corresponding to gdiag(5)='P')
1145       which are not filled-up but computed from other diags ; In this case, the mate
1146       diag points to the primary (filled-up) diag to used for post processing.
1147     - Update Velocity-potential computation using post-processed diag framework.
1148     ==> Change the ordering of fields and time-periods in MDS output file
1149       when using periodic averaging: now writes one time record with the full set
1150       of fields for this time period, then the next time reccord (it used to be
1151       one field with the full set of time records then the next field).
1152         Note: this is now similar to NetCDF (MNC) output file. <==
1153    
1154    checkpoint62z (2011/06/21)
1155    o adjoint monitor:
1156     - Add adjoint monitor output for packages exf, seaice
1157       and update relevant testreport output
1158    o pkg/seaice:
1159     - re-order diags inits so that they appear in order in available_diagnostics.log
1160     - added diags: hsnow thermo. rates of change, area preceeding ridiging process,
1161       area/heff/hsnow preceeding thermodynamic growth/melt.
1162     - modified diag: SIdA; output actual effect, as the description states.
1163     - modified description: SIqneti, SIqneto, SIuheff, SIvheff, SIdAb*, HSNOW.
1164     - retired redundant diags: SIyneg, SIfice, SIsnwice, SIthdgrh.
1165       (SIyneg->SIdHbOCN; SIfice->SIdHbATC; SIsnwice->SIdHbFLO;
1166        and SIthdgrh->SIdHbOCN+SIdHbATC+SIdHbATO)
1167     - modified diags (2) : switch all SIdA*, SIdH*, SIdS* from delta to rates.
1168     - added diagnostics for seaice generic tracers (SItr*).
1169     - added SItrUnit and SItrNameLong run time param (for SItr* diags).
1170     - in diag names, replaced 'PrTh' abbrev. of 'preceeding thermo' with 'PT'.
1171     I. Fenty: 18-Jun-2011:
1172     Minor changes to seaice package:
1173     1) Retired old variables (A22, SEAICE_lhsublim, areaMax, areaMin, hiceMin) and
1174        added some new ones (SEAICE_area_reg, SEAICE_hice_reg, SEAICE_area_floor)
1175       - Differentiated "regularization variables" from "floor variables"
1176        * areaMin became SEAICE_area_reg (old A22) and SEAICE_area_floor
1177        * hiceMin became SEAICE_hice_reg (old hiceMin)
1178          (with _reg meaning regularization variable)
1179       - SEAICE_lhSublim becomes lhSublim, the sum of SEAICE_lhEvap and SEAICE_lhFusion
1180        so as to ensure energy conservation when going between phases
1181      - A22 was not used anywhere
1182     2) Changed regularization procedure for heffActual and hsnowActual to ensure
1183        well-boundedness and smooth adjoint in seaice_growth.F
1184     3) Fixed a bug where seaice_solve4temp would not recognize ice-free grid cells
1185        because the old regularization always set heffActual >= 0.05 cm
1186     4) Changed the model so that the default behavior is to put a small (10^-5) "floor"
1187        on AREA when HEFF > 0.
1188      - went from requiring ALLOW_PRECLUDE_INFINITESIMAL_AREA to be defined to
1189        requiring that DISABLE_AREA_FLOOR *not* be defined
1190     Affected verifications:
1191      - 1D_ocean_ice_column (output.txt output_adm.txt)
1192      - global_ocean.cs32x15 (output.seaice.txt output_adm.seaice.txt)
1193    o pkg/diagnostics:
1194      - move MNC code from diagnostics_out.F into new diagnostics_mnc_out.F (2 S/R).
1195      - rename S/R GETDIAG to DIAGNOSTICS_GET_DIAG and change type of 1rst argument
1196        (was _RL, now integer) with option = 0 to retrieve all levels.
1197      - add pieces of code to compute velocity potential at each level (new diagnostics
1198        PhiVEL, works only when UVELMASS & VVELMASS are also turned on);
1199        for now, using same params as CG2D (target-resisual, max Nb of iter ...).
1200      - fix few issues with counter diagnostics in diagnostics_setdiag.F &
1201        diagstats_setdiag.F (if diagnostic counter is itself a counter diag)
1202        and in diagnostics_fract_fill.F (do not need a valid pointer for the
1203        diagnostics counter-mate); check that definition of counter-diagnostic
1204        includes a valid counter-mate (in diagnostics_set_levels.F).
1205    o model/src (rStar):
1206      - add rStar scaling factor in diags_phi_hyd.F (similar to calc_grad_phi_hyd.F);
1207        affect solution only if z* with full pressure in EOS;
1208        update output of test-exp global_ocean.90x40x15.
1209    o pkg/seaice:
1210      - introduce siEps=1e-5 parameter
1211      - use areaMax in AREA update (part 4), consistent with ridging step (part 2.5).
1212      - re-organize SEAICE_ADD_SUBLIMATION_TO_FWBUDGET code.
1213      - introduce ALLOW_SITRACER and seaice_tracer_phys.F to handle generic seaice tracer.
1214        For now it covers, and was tested for, ice salinity and age (attached to HEFF),
1215        as well as ice cover age and ridging index (attached to AREA).
1216        For now the run time parameters (in data.seaice/SEAICE_PARM03) are
1217        SItrName (e.g. 'age') and SItrMate ('HEFF', which is the default, or 'AREA').
1218        Up to SItrMaxNum=3 tracers can be used simultaneously.
1219    o pkg/salt_plume:
1220      -introduce SPsalFRAC run time parameter that sets the fraction of the
1221       salt by-product of ice growth (SPsalFRAC*(1-SIsalFRAC)*salt typically)
1222       that gets vertically redistributed (fluxed down) by pkg/salt_plume.
1223    o model debug options:
1224      - Switch reading of debugMode from S/R INI_PARMS (parameter file "data", stored
1225        in PARAMS.h) to S/R EESET_PARMS (parameter file "eedata", stored in EEPARAMS.h).
1226      - Refine debug-msg printing selection (3 new levels):
1227        debugMode  : controls printing of debug messages (sequence of S/R calls).
1228        debugLevel : controls printing of algorithm-relevant auxiliary/debug messages
1229         debLevZero =  0 ; /* level of disabled aux. msg printing */
1230         debLevA =  1 ; /* level of minimum  aux. msg printing */
1231         debLevB =  2 ; /* level of low aux. print (report read-file opening)*/
1232         debLevC =  3 ; /* level of moderate debug prt (most pkgs debug msg) */
1233         debLevD =  4 ; /* level of enhanced debug prt (add DEBUG_STATS prt) */
1234         debLevE =  5 ; /* level of extensive debug printing */
1235        New debugLevel default: with default debugMode value (=F),
1236          = 2 (debLevB) or = 1 (debLevA) in case ALLOW_AUTODIFF is defined.;
1237          and if debugMode=T, default debugLevel = 4 (debLevD).
1238        Relation with previous settings:
1239         debLevB (=2) corresponds to former debLevA (=1)
1240         debLevD (=4) corresponds to former debLevB (=2)
1241        Note:
1242         a) if debugLevel=0, skip WRITE_GRID call when nIter0 > 0 (same as before);
1243         b) default debugLevel=1 is convenient in AD runs (avoid many file opening msgs);
1244            to recover previous default, set debugLevel=2 (e.g. AD-test hs94.1x64x5)
1245      - Add new parameter (printResidualFreq, read from PARM02 namelist) to print
1246        detailed CG solvers convergence; off (=0) by default, except if debugLevel=5.
1247    o pkg/obcs:
1248      - change OBCSfixTopo default from True to False (should not change the results);
1249        keep OBCSfixTopo=T in verification-exp. seaice_obcs.
1250    o pkg/thsice:
1251      - fix bug in thsice_calc_thickn.F (was introduced in version 1.18) in
1252        2nd layer seaice sublimation (unlikely to happen)
1253      - use Interior mask for OBCS in thsice_advection.F (similar to what is
1254        done in gad_advection & seaice_advection).
1255    o adjoint:
1256      bug fix spotted by Gael Forget:
1257      seaice_advection and thsice_advection still had
1258      legacy CPP options to avoid CS corner updates for adjoint
1259    o pkg/seaice:
1260      => Change some of the defaults (2011/05/29):
1261         - change SEAICEuseFluxForm default (from False to True)
1262         - change DIFF1 default (from 0.004 m/s to 0. m/s)
1263         And print warnings if DIFF1 is not set in data.seaice and centered
1264          avection scheme is used without any diffusion.
1265      also:
1266      - fix seaice_diffusion calls in default AdvScheme part of seaice_advdiff.F;
1267      - set SEAICEdiffKh[] default in the same way as SEAICEadvSch[]
1268      - stop if DIFF1<>0 with SEAICEadvScheme <> 2, if DIFF1<>0 with any
1269        other non-zero SEAICEdiffKh[] diffusivity, if SEAICEadvSalt=T with
1270        #undef SEAICE_VARIABLE_SALINITY, if SEAICEadvAge=T with #undef SEAICE_AGE.
1271      update results of test exp.:
1272         lab_sea: output.fd (switch to AdvScheme=33 with diffKh=20)
1273             output.hb87, output_adm.evp (SEAICEuseFluxForm=T and diffKh=200)
1274             output_adm.noseaicedyn (SEAICEuseFluxForm=T)
1275         offline_exf_seaice: output.seaicetd, output_adm (SEAICEuseFluxForm=T)
1276         seaice_obcs: output (SEAICEuseFluxForm=T)
1277      and prescribe old default for SEAICEuseFluxForm (=F) and DIFF1 (=0.004)
1278          for standard fwd & AD lab_sea tests (to keep the same output).
1279    o pkg/seaice/seaice_growth.F:
1280      - use Ian Fenty's capping formulas for actual ice
1281      thickness thoughout EVOLUTION branch.
1282      - put treatment pathological case #2) in CPP brackets
1283      (ALLOW_AVOID_INFINITESIMAL_AREA, undef by default).
1284      - update global_ocean.cs32x15 and 1D_ocean_ice_colum results accordingly.
1285    o pkg/seaice:
1286      - seaice_diffusion.F : remove the min(DX,DY) factor permanently;
1287      pass the Laplacian diffusivity (in m^2/s) diffKh as a parameter;
1288      also pass fac as a param, which can be 1. (to update the tendency
1289      field) or the time step (to update the field itself).
1290      - seaice_advdiff.F: for multidim, call seaice_diffusion with
1291      e.g. SEAICEdiffKhHeff and with fac=1; for single-dim, call
1292      seaice_diffusion with e.g. SEAICEdiffKhHeff and with fac=time step.
1293      - SEAICE_PARAMS.h, seaice_readparms.F, seaice_check.F :
1294      hooks to handle SEAICEdiffKhHeff, SEAICEdiffKhArea, etc.
1295    o pkg/seaice:
1296      diffusion with centered advection scheme (diffus.F & advect.F):
1297      - simplify S/R DIFFUS (put deltaT & DIFF1 factor outside, move EXCH outside)
1298        to just compute the laplacian of input-field.
1299      - unroll k loop (harmonic,biharmonic diff) in advect.F to save 1 exch call.
1300      - fix flux-form version in diffus.F to conserve tracer.
1301      update output of lab_sea.fd & lab_sea.hb87 (1rst set of modif affects
1302       machine truncation) and lab_sea.salt_plume (conservative flux-form modif)
1303    
1304    checkpoint62y (2011/05/26)
1305    o pkg/seaice:
1306     - seaice_growth.F : in EVOLUTION branch, always include
1307       a_QSWbyATM_cover in qnet (as it should be).
1308     - verification/global_ocean.cs32x15 : update results accordingly
1309       (output.seaice.txt output_adm.seaice.txt).
1310    o pkg/seaice + obcs:
1311     - use maskInW & maskInS in multi-dim advection and biharmonic diffusion:
1312       equivalent of assuming no tracer gradient outside the OB region.
1313       update output of seaice_obcs (uses DIFF1 <>0 => biharmonic diffusion)
1314     - remove calls to OBCS_COPY_TRACER after EXCH calls (no longer needed
1315       after changes above);
1316     - obcs+seaice cleaning: apply seaice-tracer OB values to tracer field
1317       only at OB location (instead of over a band of OLx width).
1318    o pkg/seaice:
1319     - fix wrong indices in old (non Flux-Form) diffusion default S/R diffus.F
1320       (dxG(I+1, ...) changed to dxG(I, ...), no impact on Lat-Lon grid)
1321    o pkg/obcs:
1322      - split header file "OBCS.h" into 4 separated files:
1323        OBCS_PARAMS.h, OBCS_GRID.h, OBCS_FIELDS.h & OBCS_SEAICE.h
1324       Note: OBCS_PARAMS.h & OBCS_GRID.h can be included without OBCS_OPTIONS.h
1325         (contain no conditional statement which depends on OBCS options).
1326      - move "useOBCSYearlyFields" from "data.obcs" (hold in OBCS_PARAMS.h)
1327        to parameter file "data.exf", namelist EXF_NML_OBCS (in EXF_PARAM.h).
1328    o ctrl, cost, grdchk & autodiff pkgs:
1329      - make options file more standard (like other {PKG}_OPTIONS.h file but
1330        with AD_CONFIG.h); clean-up some of the included header files.
1331    o pkg/obcs:
1332      - do not mask tracer when applying OB (tracer == 0 could generate problems)
1333      - apply tracer OB values to tracer field only at OB location (instead of
1334        over a band of OLx width)
1335      - clean-up obcs_apply_w.F & obcs_apply_eta.F (since less calls to these S/R)
1336      - remove OBCS_MULTIDIM_OLD_VERSION code in gad_advection.F and remove
1337        obcs_apply_tloc.F & obcs_apply_sloc.F
1338    o obcs in model/src:
1339      - call OBCS_APPLY_W only if NonHydrostatic.
1340      - call OBCS_APPLY_ETA only if NonLinFreeSurf.
1341      - reset dEtaHdt and wVel to zero outside OB interior region ;
1342      - leave tracer unchanged outside OB interior region: This has no effect
1343        on the solution but just to prevent unrealistic tracer value outside OB.
1344      - zero out velocity outside OB interior region: This has no effect on
1345        the solution but just to prevent unrealistic velocity outside OB.
1346    o obcs and non-lin free-surf:
1347       move call to OBCS_APPLY_R_STAR from update_r_star.F to calc_r_star.F
1348       and call to OBCS_APPLY_SURF_DR from update_surf_dr.F to calc_surf_dr.F
1349       + add argument "etaFld" to OBCS_APPLY_R_STAR & OBCS_APPLY_SURF_DR:
1350       this fixes missing EXCH + get consistent eta OB value (+ fix restart).
1351       update results of test-exp. exp4(nlfs).
1352    o exp4 (nlfs) test-exp:
1353       use OBC for Eta at Western & Eastern OB (to test prescribing Eta
1354       with NonLin-FreeSurf); update output.nlfs.txt
1355    o obcs and 2d/3d solver norm:
1356       use interior masks (maskInC) to cancel out cg2d & cg3d matrix coeff at OB
1357       and outside OB interior region (will allow to place OB further inside the
1358       domain). Depending on the domain, can affects cg2d-Norm (previous
1359       cancellation outside OB was only partial), e.g. in exp4 & obcs_ctrl,
1360       and cg3d-Norm (previous Norm was computed before canceling OB terms),
1361       e.g. in tutorial_plume_on_slope.
1362      - update output of exp.: exp4 (x2), obcs_ctrl and tutorial_plume_on_slope.
1363    o pkg rbcs:
1364      - split RBCS.h into 3 files: RBCS_SIZE.h, RBCS_PARAMS.h & RBCS_FIELDS.h
1365      - add capability to apply relaxation to horizontal velocity uVel & vVel.
1366    o pkg/grdchk: add gradient check for control variable xx_shifwflx
1367    o pkg/shelfice/shelfice_init_fixed.F
1368      fix CPP-flag combinations
1369    o pkg/seaice: Merge iceage code of Pierre Rampal
1370      * update/change/correct ice age calculations
1371      * add age updates for pathological cases
1372      Probably needs more testing...
1373    
1374    checkpoint62x (2011/05/13)
1375    o pkg/mom_vecinv:
1376       high-order vorticity scheme: use interior masks (maskInW & S)
1377       to zero-out (outside OB) gradient of vorticity.
1378    o verification exp.:
1379       turn on "useEnergyConservingCoriolis" (better discretisation) in exp.
1380       hs94.128x64x5 and seaice_obcs ; update results.
1381    o pkg/obcs:
1382      fix bug in OBeta for YZ sections in obcs_exf_load.F
1383    o pkg/ctrl, pkg/shelfice, and optim:
1384      - add new control variable xx_shifwflx (fresh water flux underneath ice
1385        shelves). This is almost as tedious as obcs-ctrl, because the
1386        variables needs its own mask.
1387      - add a cost function term that penalizes the deviation of xx_shifwflx
1388        from the first guess (zero) in analogy to other control variables
1389    o pkg/shelfice:
1390      - start basic adjoint
1391    o pkg/ctrl:
1392      - remove extra 2D field "for good measure" when initializing in
1393        ctrl_set_globfld_[xy/xz/yz].F
1394      - replace hard coded precision 32 (a bug) in ctrl_map_ini_gen by ctrlprec
1395      - improve error messages in ctrl_set_unpack_*
1396    o OBC implementation in momentum:
1397       use interior masks (maskInC,W & S) in momentum S/R:
1398       - multiply divergence, tension and some del^i.u or del^j.v by maskInC
1399       - multiply del2u,del2v by maskInW/S (biharmonic viscosity)
1400       - multiply horiz. grad of vorticity by maskInW/S (in Leith scheme)
1401       - multiply gradient of wVel by maskInW/S in del2w calculation (NonHyd)
1402       Motivation: fix/clean implementation of OBC with biharmonic-viscosity
1403        (and also with Leith/Smagorinsky harmonic-viscosity).
1404       Update output of experiment dome and exp4 (+nlfs).
1405    o exp4 test-exp:
1406      - turn on: nonHydrostatic, exactConserv, viscA4 (with momDissip_In_AB=F)
1407        and prescribe time-varying OB (without pkg/exf) for zonal-velocity
1408        at Western & Eastern Boundaries (+/- 1 per-cent); Also prescribe
1409        time-varying OB at Western-side for wVel (NonHyd); update output.
1410      - add secondary set-up (.nlfs) using NonLin FreeSurf (z*) + mom_vecinv
1411        and biharmonic-viscosity ; also use prescribed time varying OB.
1412    o pkg/obcs:
1413      fix bug in OBWeta,OBWeta indices in obcs_apply_r_star.F
1414    o model/src:
1415      - fix startTime setting when baseTime<>0 & nIter0=0 are specified ;
1416      - initialise startTime & nIter0 with unlikely values: allows to set one
1417        from the other without ambiguity.
1418    o seaice_obcs test-exp.:
1419      add small diffK4T,S to test biharmonic diffusivity with OBCS ; update output.
1420    o pkg/obcs:
1421      - remove calls to OBCS_COPY_TRACER after EXCH for T,S & pTracer:
1422        no longer needed with maskInC,W,S in pkg/generic_advdiff.
1423    o pkg/seaice:
1424      - retired SEAICE_SALINITY and SEAICE_salinity in favor of
1425        SEAICE_VARIABLE_SALINITY and SIsalFRAC, respectively.
1426      - fixed bug in the initialization of sea ice salinity variable HSALT
1427        in seaice_init_varia.F  (removed dependence on ICE2WATR)
1428    o fizhi-cs test exp.:
1429       switch reference output convention for these 2 non-standard test-exp,
1430        from: pgi  6.1-5 on faulks (FC.6, -of linux_ia32_pgf77+authors_fc5)
1431          to: ifort 11.1 on baudelaire (FC.13, -of linux_amd64_ifort11)
1432       reason: faulks might get retired soon and pkg/fizhi has still Pb with gfortran
1433    o model/inc:
1434      - change type of PmEpR array (from _RS to _RL) to fix restart (with "-use_r4")
1435        of exp. global_ocean.90x40x15 (Suncronous time-stepping + Real-FW + NonLin-FS)
1436    o pkg/seaice:
1437      - fix calculation of saltFlux and saltPlumeFlux when using SEAICE_SALINITY
1438    o verification/lab_sea, 1D_ocean_ice_column, seaice_obcs, global_ocean.cs32x15
1439      - updated output*.txt files due to bug fixes in salt, saltPlumeFlux,
1440        and initial HSALT
1441    
1442    checkpoint62w (2011/04/26)
1443    o pkg/mom_fluxform:
1444      - fix calculation of del2u & del2v (no-slip BC) when using Non-Lin Free-Surf.
1445      - use parameter "sideDragFactor" in no-slip BC side-drag part.
1446      - update output of exp. global_ocean.90x40x15
1447    o pkg/mom_vecinv:
1448      mask del2u & del2v (no effect on results, but cleaner & closer to mom_fluxform)
1449    o update seaice exp.:
1450      use more consistent parameter values (remove "backward compatability only":
1451       ICE2WATR, SEAICE_lhSublim, SEAICE_cpAir, SEAICE_rhoAir + set rhoConstFresh)
1452      related to thermodynamics seaice. Update output (fwd+AD) of exp.:
1453       1D_ocean_ice_column (x2), lab_sea (x8), ioffline_exf_seaice (x2) & seaice_obcs
1454    o update test-exp global_ocean.90x40x15:
1455      o use default CD_CODE_OPTIONS file (Adams-Bashforth on CD Mom & Coriolis).
1456      o increase Overlap size from 2 to 3 (to allow to test bi-harmonic Visc.)
1457      o new pickup-files from a 100.yr run with pkg/down_slope (input.dwnslp params)
1458      o turn on zStar & viscA4 in standard set-up (dir input/)
1459        and update output files: output.txt & output.dwnslp.txt
1460    o new AD-test experiment: obcs_ctrl
1461      (From Matt MITgcm_Contrib/SOSE/BoxAdj) to test OBCS as control vector.
1462    o pkg/dic:
1463      fix two bugs in handling water vapour pressure in carbonate chemistry
1464      and air-sea fluxes. Found by Val Bennington and Galen McKinley
1465      (add DIC Option = WATERVAP_BUG to recover old results)
1466      update output of tutorial_global_oce_biogeo (fwd+AD) & tutorial_dic_adjoffline
1467    o adding allowInteriorFreezing option to check for water below freezing point
1468      at depth and bring the negative heat anomaly to the surface level
1469    o pkgs _fields_load:
1470      - extend GET_PERIODIC_INTERVAL to deal with non-periodic case (from pkg/rbcs)
1471      - use new S/R GET_PERIODIC_INTERVAL in pkgs:
1472        bulk_force, cheapaml, cfc, dic, obcs (+ ctrl/ctrl_get_gen_rec), offline and
1473        rbcs to get interpolation weights and time reccord number.
1474      - fix multi-threading in aim_fields_load.F
1475      - apply EXCH to temp arrays [0,1] after reading in dic_fields_load.F
1476    o external_fields_load:
1477      new S/R GET_PERIODIC_INTERVAL to calculate which time-record (and linear
1478       interpolation weights) to use in a periodic time-series ; do not divide by
1479       time-step to convert to integer:
1480       - this fixes case where externForcingPeriod is not multiple of time-step
1481          (Thanks to Christopher L. Wolfe)
1482       - this fixes case where externForcingPeriod is an odd multiple of time-step
1483         (was wrong by half of time-step); update results of tutorial_global_oce_in_p.
1484      store index of time-record which is currently loaded:
1485       - works without any assumption on sequence of calls to EXTERNAL_FIELDS_LOAD ;
1486       - needed for the adjoint but not yet used because of extensive recomputations;
1487         (to be fixed soon)
1488    
1489    checkpoint62v (2011/04/02)
1490    o verification/1D_ocean_ice_column added to test Ian Fenty's
1491      pkg/seaice_growth.F modifications for improving sea ice code differentiability
1492    o update output of exp4, internal_wave, seaice_obcs, tutorial_plume_on_slope
1493      (new velocity statistics after changing maskInW & maskInS definition)
1494    o pkg/generic_advdiff with OBCS:
1495      use maksInW & maskInS in advective flux and in biharmonic diffusion calculation:
1496      equivalent to assumption of no tracer gradient outside the OB region.
1497      This will affect the results if using obcs+biharmonic diffusion.
1498      update output_adm.txt of experiment bottom_ctrl_5x5 (not expected since no obc)
1499    o pkg/obcs:
1500      change definition of maskInW & maskInS: leave OB edges inside (maskIn=1)
1501      (e.g., maskInW(OB_Ie)=1 ) so that velocity normal-component at OB is still
1502      in Interior region. No impact on solution but affects Velocity monitor stats.
1503    o pkg/ptracers (adjoint)
1504      New option AUTODIFF_PTRACERS_SPLIT_FILES for writing separate
1505      tape file for each tracer
1506    o model/inc/src and pkg/autodiff: add parameters that allow to turn
1507      of parts of the adjoint code at run time. For now, there are only
1508      useKPPinAdMode, useGMrediInAdMode, and useSEAICEinAdMode. These
1509      parameters are set in data.pkg.
1510      This is the lazy coward's version of doing this, but still useful for
1511      debugging. In order to do it right, everything needs to be moved to
1512      pkg/autodiff.
1513    o pkg/autodiff: fix global_sum_tile_ad.F by resetting adsumPhi at
1514      the end; this fixes the adjoint balancing code for open boundaries.
1515    o pkg/ctrl:
1516      - change behavior of xx_${varname}period to be analogous to exf-conventions:
1517        xx_${varname}period =   0.,  means time-independent control part
1518        xx_${varname}period = -12., means one-year-periodic monthly control part
1519      - introduce helper routine ctrl_init_rec (part of ctrl_init.F) to
1520        clean up ctrl_init a little, remove unused variables
1521      - ctrl_init: fixed the handling of the start/endrec for obcs-variables
1522      - move "call cal_GetMonthsRec" from s/r ctrl_get_gen to s/r ctrl_get_gen_rec
1523    
1524    checkpoint62u (2011/03/15)
1525    o model/src:
1526      - for the adjoint, change NonLin-FreeSurf initialisation sequence: fill-in
1527        h0Fac from INITIALISE_FIXED and reset hFac to h0Fac in INITIALISE_VARIA ;
1528      - in initialise_varia.F (except for ALLOW_DEPTH_CONTROL) remove 2nd call to
1529        INI_DEPTHS, INI_MASKS_ETC & INI_LINEAR_PHISURF.
1530    o pkg/ctrl/obcs/ecco:
1531      - remove obsolete, unused, and partially broken code:
1532        ctrl_obcsvol/ctrl_obcsbal/ctrl_volflux and code within
1533        ALLOW_CTRL_OBCS_BALANCE
1534      - put a stop statement into ecco/cost_obcsvol.F, but also add
1535        cost_obcsvol to ecco_ad_diff.list
1536    o pkg/ecco: fix counting cost function contributions for obcs (code
1537      by Matt M.) and diffkr for diagnostics
1538    o pkg/ecco, pkg/ctrl, pkg/grdchk:
1539      add cost penalty terms for initial uvel, vvel, eta controls
1540      and I/O for prior error files
1541    o pkg/mdsio:
1542       move mds_check4file.F from eesupp/src to mdsio_check4file.F ; add option
1543       (new argument) to check for tiled file in mdsioLocalDir : this fix the
1544       restart from pickup_som , pickup_dic (& dic_co2atm) with mdsioLocalDir.
1545    o pkg/ctrl:
1546     - ctrl_obcsbal.F, ctrl_obcsvol.F: replace last calls of ctrl_getrec by
1547       ctrl_get_gen_rec, put a stop statement into ctrl_getrec. Remove
1548       unused and superfluous variables
1549     - ctrl_get_gen_rec.F: catch the case of xx_genperiod=0.
1550    o pkg/ecco
1551     - enable adjoint of Stevens OB
1552    o pkg/ctrl/ecco/grdchk:
1553      - remove global declaration of tmpfldx/yz and tmpfldx/yz2.
1554        Fortunately, we do not have any tests for the numerous cpp-flagged
1555        option of "obcs as control parameters" so we will never know
1556        if this is an improvement (but at least now things compile).
1557      - remove an obsolete initialization from ecco_cost_init_barfiles.F
1558      - fix some problems within never used ifdefs to make the code compile
1559    o pkg/obcs:
1560     - Refine Interior mask definition to work with more complex OB (e.g.
1561       if OB_Ie < OB_Iw); In case default setting is not sufficient, allows to
1562       read in Interior mask from file. Check if Interior mask is consistent
1563       with OB list of indices.
1564    o pkg/seaice
1565     - beginning code for a seaice tracer package,
1566       but currently only used for seaice age: SEAICE_AGE
1567       SEAICE_num = 4
1568       iTracer = 1: area-weighted ice age
1569               = 2: volume-weighted ice age
1570               = 3, 4: template for one-year vs. multi-year ice
1571       data.seaice has new namelist SEAICE_PARM03 for arrays related to
1572       SEAICE_num
1573    
1574    checkpoint62t (2011/03/05)
1575    o pkg/obcs:
1576     - obcs_apply_uv.F: change to a 2 steps method, first tangential component;
1577       then normal component. This ensures that the normal component is set
1578       correctly even when it conficts with tangential setting from an other OB.
1579       Affects results of test-experiment seaice_obcs: update the output.txt
1580    o pkg/obcs:
1581     - add code to monitor statistics of dynamical fields at OB.
1582     - take OBCS_BALANCE code out of obcs_calc.F into new S/R OBCS_BALANCE_FLOW :
1583       - fix to OBCS_BALANCE code (right hFac ; deal with simple OB intersection).
1584       - change default: balance the Net inflow through all OB (instead of balancing
1585         each OB separately); keep the old method if setting OBC_balanceFacX < 0.
1586     - switch on useOBCSbalance in dome experiment: only correct Western OB outflow
1587       to match Nortern OB inflow (OBCS_balanceFacN=0).
1588    o pkg/seaice:
1589     - redefined actual sea ice age to be ICEAGE/HEFF ifdef SEAICE_AGE_VOL
1590    o pkg/seaice (seaice_growth v 1.113):
1591     - reverting seaice_growth to v 1.111 in order to have code with exact bit
1592       compatibility with MITgcm_contrib/ifenty/Fenty_seaice_thermo_code_merge
1593       CPP option SEAICE_OCN_MELT_ACT_ON_AREA removed in v 1.112 is reintroduced
1594       runtime flag SEAICEareaFormula is kept but is inactive
1595    o model/src:
1596     - add new param to scale curvilinear grid distance and area when using
1597       a different sphere radius from the grid-files.
1598     - test/check multi-threads EXCH applied to local variable (cg2d_x)
1599    o adjoint:
1600     - enable adjoint of Stevens OB
1601     - add dummy_in_dynamics to enable extraction of ADJrhoinsitu
1602       (a bit delicate because of potentially modified adj. common block structure;
1603       current switch is ALLOW_AUTODIFF_MONITOR_DIAG, could be changed later)
1604    
1605    checkpoint62s (2011/02/15)
1606    o pkg/seaice (seaice_growth v 1.112):
1607     - introduce SEAICEareaFormula run time parameter, which selects the recipe for
1608       computing the ice cover tendency from effective thickness tendencies. Include
1609       Ian Fenty's formula.
1610     - remove 'undef SEAICE_OCN_MELT_ACT_ON_AREA' which may now be achieved using
1611       SEAICEareaFormula.
1612     - simplify notations for the various d_HEFF/d_AREA terms.
1613    o pkg/gmredi:
1614     - add Boundary-Value-Problem bolus transport (Ferrari etal, OM 2010) code
1615       from Christopher Wolfe (UCSD); add partial cell factor in vertical derivative;
1616       add a verification test-run (front_relax.bvp) to test GM_useBVP.
1617    o pkg/seaice (seaice_growth v 1.111):
1618     - for SEAICE_DO_OPEN_WATER_GROWTH, replace Gael's implementation with Ian's.
1619     - the new SEAICE_DO_OPEN_WATER_MELT allows open-water air-sea heat fluxes to
1620       also melt ice.
1621    o pkg/seaice:
1622     - McPhee formula for Ice-Ocean fluxes (provided by Ian Fenty).
1623     - can be used by #define MCPHEE_OCEAN_ICE_HEAT_FLUX in SEAICE_OPTIONS.h
1624    o pkg/cheapaml:
1625     - from Nico Wienders: New version of this package.
1626    o pkg/flt:
1627     - add CPP options to prevent floats to re-enter the opposite side of
1628       a periodic domain (default: keep periodicity)
1629    o pkg/gmredi:
1630     - apply exchange to GM_PsiX,GM_PsiY to get valid values near CS-corners
1631       (needed for multi-dim advection).
1632     - switch on GM Advective form in global_ocean.cs32x15 and update output.txt
1633    o model/src:
1634     - fix wrong re-setting of addMass array (ALLOW_ADDFLUID) for atmospheric run.
1635    o tutorial_tracer_adjsens
1636     - extend to NLFS and replace maskC by hFacC
1637       (change reference output accordingly)
1638    
1639    checkpoint62r (2011/01/24)
1640    o testreport:
1641     - add option -deloutp (-do) to remove output file after successful run
1642     - add option -mfile (-mf) for MPI machile-file and for each test-exp,
1643       extract exact list of procs from this file ; adjust COMMAND by
1644       replacing TR_MFILE & TR_NPROC with local machile-file & Nb of MPI procs.
1645    o pkg/ecco: replace old ineffective way of penalizing deviations from
1646      first guess (of obcs) with code by Matt Mazloff
1647    o pkg/ctrl: add code that allows the use of ALLOW_OBCS?_CONTROL without
1648      exf/cal
1649      - ctrl_init: fix initialisation (computation of diffrec) for obcs-ctrl
1650        and handle case of obcs?period == 0
1651        Not affected by these changes: There is still an inconsistency in
1652        the computation of start/endrec for the obcs variables for ALLOW_CAL
1653        defined (see comment by Menemenlis, 7-Mar-2003)
1654      - make S/R ctrl_get_gen_rec return something meaningful even if
1655        ALLOW_CAL is not defined
1656      - ctrl_getobcs?: simplify code so that it does not need to use
1657                       S/R exf_swapfields
1658    o testreport:
1659       allow to test MPI with different number of processors for each experiment:
1660       create file "SIZE.h.mpi" in each build dir.
1661       Note: update of "-command" argument not yet implemented.
1662    o model/src, pkg/autodiff, pkg/ecco, pkg/seaice:
1663      alleviate the need for additional 3D tapes when using
1664      the non-inear free surface in the adjoint. This is done
1665      by adding an 'update' of hfacc etc. to their current
1666      value at the beginning of forward_step.F.
1667    o pkg/seaice
1668      seaice_lsr: move stress-divergence computations out of outer pseudo-
1669      timestepping loop
1670    o pkg/obcs/obcs_prescribe_read.F: move 'CALL OBCS_EXTERNAL_FIELDS_LOAD'
1671      up, so that the calls of the ctrl_* subroutines are really at the end
1672      of the routine.
1673    o pkg/gmredi:
1674      allow to specify a 2-D horizontal map and a 1-D vertical profil
1675      as scaling factor for Isopycnal diffusivity (Redi) and GM diffusivity.
1676    o pkg/seaice:
1677      move lsr iterations from seaice_dynsolver to seaice_lsr.
1678    o pkg/seaice:
1679      reduce memory footprint of seaice mutldim advection tapes,
1680      by using a 2D tape independent of the generic_advdiff ones,
1681      and setting GAD_AREA=1 etc. rather than GAD_AREA=101 etc.
1682    
1683    checkpoint62q (2010/12/29)
1684    o model/src:
1685      - check horizontal grid-spacing for unset or zero/negative values.
1686      - change AD test hs94.1x64x5 to be truly a 2-D set-up.
1687    o pkg/flt:
1688      - use (recent) mdsio S/R MDS_READVEC_LOC instead of local FLT_MDSREADVECTOR
1689      - precision of input and output files set according to readBinaryPrec
1690        and writeBinaryPrec (previously always 64.b), pickup remains at 64 bits.
1691      - initial float position from tiled file was not converted to index space
1692        (looks like a bug): fixed to make it similar to initial pos. global file.
1693    o global_ocean.cs32x15:
1694       change SIZE.h of AD set-up to get same tiling as with MPI.
1695       Update output_adm, output_adm.thsice (pass@14) & output_adm.seaice (fail@11)
1696    o model/src:
1697       add flag to control printing of domain fields (bathymetry, hFac ...) in
1698       ini_mask_etc (call to plot_fieds_xy*).
1699    o pkg/thsice:
1700       if useEXF, some forcing fields are not valid in overlap: fixed by computing
1701       over the interior only + apply EXCH at the end (like with SEAICE advection).
1702    o pkg/mdsio:
1703      - add 2 arguments to S/R MDS_PASS_R4/8toRL/S for overlap size of buffer
1704        to copy to/from, so that it can be used to replace MDS_PASS_WH_R8toRL/RS.
1705      - change barrier call for safe multi-threads access to 3-D shared buffer.
1706      - MDS_READ/WRITEVEC_LOC use buffers from MDSIO_BUFF_3D.h (instead of local ones)
1707      - replace call to MDS_PASS_WH_R4/8toRL with call to MDS_PASS_R4/8toRL and
1708        remove the 4 S/R MDS_PASS_WH_R4/8toRL/S.
1709    o pkg/flt:
1710      - add fourth-order Runge-Kutta integration
1711      - add basic exch2 support (only 1 facet supported so far!)
1712    o pkg/mdsio+rw:
1713      new S/R to read local (or tile independent) vector (read counterpart of
1714       mds_writevec_loc, and front-end write_glvec_rl/rs).
1715    o global_ocean.cs32x15: additional input_ad.seaice experiment
1716        that uses pkg/seaice rather than pkg/thsice.
1717        (using multidim advection for seaice)
1718    o towards more F95 syntax for array specification in namelist:
1719      - change "data.diagnostics" (data.ptracers was changed before checkpoint62p)
1720        of all verification experiments.
1721           e.g.:    line: fields(1,3)='ETAN    ','ETANSQ  ',
1722          was changed to: fields(1:2,3)='ETAN    ','ETANSQ  ',
1723      - finish adding "-DNML_EXTENDED_F77" to DEFINES list in pgf77 and g77 optfiles
1724    o global_ocean.cs32x15: additional input.seaice experiment
1725        that uses pkg/seaice rather than pkg/thsice.
1726    
1727    checkpoint62p (2010/12/17)
1728    o pkg/thsice: rename (ad tape index) iicekey as ticekey, and move it
1729        to THSICE_SIZE.h to avoid conflict with pkg/seaice.
1730    o pkg/seaice: add seaice_diffusion.f seaice_map_thsice.f to adjoint.
1731        allow for use of multim. advection in seaice adjoint.
1732    o pkg/seaice: add diagnostics for snow precipitation and sublimation flux
1733      - first attempt to close budgets by taking into account the freshwater
1734        flux implied by the sublimation of snow and ice. So far only the
1735        volume budget is closed, turn on with soon-to-be-retired-again CPP-Flag
1736        SEAICE_ADD_SUBLIMATION_TO_FWBUDGET
1737    o eesupp/src:
1738      new S/R with new option (NML_EXTENDED_F77) to change array specification
1739      from F95 standard to commonly accepted extended F77 form.
1740      This would allow to use F95 syntax in namelist (needed with gfortran 4.4.5)
1741      and to revert back to the original syntax (with -DNML_EXTENDED_F77)
1742      for less tolerant f77 compiler (e.g., pgf77, g77).
1743    o globalFiles:
1744      commented out in parameter file "data" since it's not safe with MPI
1745      (e.g., wrong on aces); keep it if useSingleCpuIO=T (but not doing much
1746      in this case); no longer commented out in restart test (tst_2+2).
1747    o add adTapeDir to specify a special directory where adjoint tapes are
1748      written/read (adread_adwrite.F). adTapeDir is specified in data/PARM05
1749      and cannot be used together with mdsioLocalDir.
1750    o nesting pkgs:
1751      - packages_init_variables : put call to OBCS_INIT_VARIABLES in last position
1752      - update Gianmaria's Nesting pkgs (from Contrib/nesting_sannino)
1753      - add parameter files + utils dir + output from short run on beagle.
1754    o pkg/seaice:
1755        fix seaice_growth.F store directives; update results of exp. lab_sea.ad
1756    o pkg/seaice: explicitly store tsurfloc in seaice_solve4temp.F to avoid
1757      unnecessary copying in adjoint code, requires new parameter NMAX_ITER
1758    
1759    checkpoint62o (2010/11/25)
1760    o pkg/exf:
1761      - change CPP option EXF_VERBOSE to run-time logical param exf_verbose.
1762    o pkg/seaice:
1763      - seaice_ocean_stress: split a loop for better vectorization of the
1764        adjoint code
1765      - seaice_growth.F: fix bug in conservation of freshwater connected to
1766        capping of heff, put contribution into d_HEFFbyNEG
1767      - replace irritating parameters SEAICE_latentWater/Ice and SEAICE_sensHeat
1768        by something more sensible (parameters that are what their name implies)
1769      - change some defaults, so that by default exf-parameters are used for
1770        things like rhoAir, cpAir,latent/sensible heat parameters, in order
1771        to reproduce the old results, many data.seaice now contain funny values
1772        for cpAir and latent heat of sublimation
1773    o packages_readparms.F: move exf_readparms up in line so that
1774        exf-parameters are visible for other packages (e.g. seaice)
1775    o debugMode & debugLevel=2:
1776      - differentiate between debugMode & debugLevel=2:
1777        debugMode: controls printing of debug messages (sequence of S/R calls).
1778        debugLevel: controls printing of algorithm intermediate results and stats.
1779      - remove "if debugLevel=2 => debugMode" but keep "debugMode =>  debugLevel=2";
1780        => allows to print debug-stats without all sequence of call messages.
1781      - switch control of debug print from debugLevel to debugMode in many S/R.
1782    o pkg/obcs (obcs-sponge):
1783        fix bug that was introduced on Oct 25 (in dynamics.F v1.151): put back the
1784        call to OBCS_PRESCRIBE_EXCHANGES (need to exch gU,gV when using obcs-sponge)
1785    o pkg/generic_advdiff:
1786      - record overlap minimum size for each advection scheme;
1787      - refine criteria on overlap minimum size;
1788      - check and stop (in gad_check) if overlap size is too small.
1789    o pkg/obcs:
1790      - with ptracers: remove multiple calls to obcs_apply_ptracer (only done
1791        once, in ptracers_implicit.F)
1792      - with seaice: remove test on empty file name in obcs_apply_seaice (always
1793        apply OB values when tile has OB)
1794    o model/src, coriolis setting:
1795      - integer parameter "selectCoriMap" (=0,1,2) replaces 3 logical
1796        useConstantF, useBetaPlaneF, useSphereF ; can now read coriolis from
1797        files (selectCoriMap=3) with any grid.
1798      - add parameter "fPrime" for constant second Coriolis coeff (default=0).
1799    o pkg/seaice/seaice_growth.F:
1800        a few cosmetic changes that reduce the number of lines of code
1801    o pkg/obcs: add boundary conditions following Stevens (1990)
1802      - the code follows old MOM/NAOSIM code
1803      - so far it is only implemented for the eastern and western boundaries
1804        and NOT for pTracers
1805    o pkg/rbcs:
1806      - replace rbcsInIter by rbcsForcingOffset, the time in seconds at the
1807        beginning of the first rbcs forcing period.
1808      - add option rbcsSingleTimeFiles that makes rbcs read forcing data like the
1809        offline package, i.e., one file per time, labeled by iteration number;
1810        deltaTrbcs sets the timestep with which the data was generated;
1811        rbcsIter0 is the forcing iteration corresponding to rbcsForcingOffset.
1812      - rbcsForcingCycle=0 makes forcing non-cyclic.
1813      - make arithmetic safe for negative times and odd forcing periods.
1814    
1815    checkpoint62n (2010/11/09)
1816    o pkg/seaice:
1817        fix masking in free-drift S/R ; update results of exp. lab_sea.fd
1818    o pkg/obcs:
1819       New S/R to copy tracer value from the OB location to narrow band region
1820        (width = same as overlap) beyond the OB: preserve OB value (needed for
1821        high-order scheme) which were overwritten by EXCH call if in overlap
1822        region. Applied to theta, salt, ptracer and advected seaice variables.
1823       With seaice: use maskInC in similar way as in gad_advection.F,
1824        in seaice_advection.F and advect.F.
1825       Update output of experiment seaice_obcs and change exp4 to test OBCS with
1826        4th order Adv.Scheme. for pasive salt and ptracer.
1827    o tools/genmake2:
1828      - when looking for an optfile (not specified), only search for Fortran compiler
1829        (remove sym-link test + setting of CPP + makedepend check + C-compiler check)
1830      - in get_fortran_c_namemangling: use "$CC $CFLAG" to compile C test programm
1831        (instead of "$MAKE genmake_test.o" since an existing Makefile can be wrong)
1832      - set default for CPP to "cpp -traditional -P" (was the case without specifying
1833        an optfile, but otherwise default was just "cpp".
1834      - comment out PLATFORM=$p_PLATFORM (no idea where p_PLATFORM comes from)
1835      - when "CC" is not set in the optfile, look for possible C compiler
1836        (instead of just setting CC=cc)
1837      - put back version v.169 modif (from 2008/02/15), was dropped in v.173 changes:
1838        => add a ".F" to ".o" rule for source files with no "#include" (such as
1839           port_rand.F); otherwise, default ignores FOPTIM and just uses FFLAGS.
1840      - move gfortran before g77 in list of possible Fortran compiler (consistent
1841        with reference compiler switch from g77 to gfortran)
1842    o pkg/seaice:
1843      o remove SEAICE_OLD_AND_BAD_DISCRETIZATION-code, add a test to
1844        seaice_check that stops the model, when the CPP flag is used.
1845      o seaice_growth.F: make capping of ice volume conserving by returning the
1846        capped ice as freshwater to EmPmR. This does not change the verification
1847        experiments but will change runs where the capping is acutally active
1848    o change reference platform+compiler from faulks+g77 to baudelaire+gfortran
1849      (except the 2 fizhi test exp.); update output of exp.: bottom_ctrl_5x5,
1850         global_ocean.cs32x15 (icedyn, thsice, AD thsice), global_ocean_ebm (AD),
1851         lab_sea (fd, hb87, salt_plume), MLAdjust (3/5) and vermix (dd)
1852    o tools/genmake2:
1853      - merge genmake_warnings & genmake_errors into 1 log file: "genmake.log")
1854      - change DUMPSTATE default to false (can use "-ds" option to switch it to T)
1855      - clean previous genmake log files before anything else.
1856      - change Makefile to remove testreport log files (*.tr_log) and genmake log
1857        files only with "CLEAN" target (instead of "Clean");
1858    o pkg/generic_advdiff:
1859      Change OBCS in multiDim advection (gad_advection.F):
1860       Use maskInC to prevent intermediate update of tracer-field in OB regions,
1861       thus keeping current-time-step OB values; and remove the call to OBCS_APPLY
1862       which were applying future time-step OB values.
1863      This way, all explicit calculations use current-time-step OB values
1864       (simpler and more consistent).
1865      Affects results when set-up uses time-varying OBC and multi-dim advection;
1866       update output of experiment seaice_obcs.
1867    o pkg/seaice:
1868      move OPTIONS (formerly locally defined) to SEAICE_OPTIONS.h:
1869       this includes SEAICE_GROWTH_LEGACY (+ SEAICE_DO_OPEN_WATER_GROWTH &
1870         SEAICE_OCN_MELT_ACT_ON_AREA ) and SEAICE_SOLVE4TEMP_LEGACY.
1871      Default (pkg/seaice/SEAICE_OPTIONS.h) is to define SEAICE_SOLVE4TEMP_LEGACY
1872       but leave SEAICE_GROWTH_LEGACY undef ; For now, keep verification exp
1873       unchanged (SEAICE_GROWTH_LEGACY defined in */code*/SEAICE_OPTIONS.h)
1874    o pkg aim (2010/10/26):
1875      - Introduce ALLOW_INSOLATION, moving toward a more general incoming solar radiation
1876        formulation with obliquity, eccentricity, ... as run-time parameters,
1877      - Introduce diagnostics for top-of-the-atmaophere incoming solar radiation and
1878        upward shortwave radition at the surface (all-sky and clear-sky).
1879    o pkg/obcs:
1880      - writing sections with globalFiles=T does not work: switch to tiled-files
1881        when writing sections for OBCS (change pkg/rw/write_rec.F accordingly).
1882      - fix index bug (OB_Ie -> OB_Iw_) in obcs_apply_uvice.F
1883      - apply OBCS_SEAICE_COMPUTE_UVICE to both uice and vice at all obcs
1884    
1885    checkpoint62m (2010/10/21)
1886    o pkg/seaice: vectorize seaice_solve4temp.F
1887      - move iterations loops outside of i/j-loops
1888      - requires 2D arrays for TB and effConduct
1889      - add 2D iceOrNot to replace HICE_ACTUAL.GT.0, as HICE_ACTUAL is
1890        modified in this routine
1891      - a little bit of clean up, adjusting indentation, etc.
1892      - replaced a few TEN**a by exp(a*log(10.)) in new code for better
1893        performance and '**TWO' by '**2' (because TWO is a float),
1894        replaced ONE, ZERO
1895    o eesupp/src:
1896       fix flow dir for exch1_z_RX_cube, exch1_uv_RX_cube & exch1_bg_RX_cube
1897    o pkg/seaice/seaice_growth.F
1898      Revision 1.89 of seaice_growth.F completes the overall october 2010 revision and
1899      merging process. The merged routine has two branches, and one activates the 'evolution'
1900      branch by setting SEAICE_GROWTH_LEGACY to undef (at the top of the routine for now).
1901      In summary, here is what the '10/10 revision' did consist of
1902        part 1: seaice_growth.F revisions 1.71 to 1.75
1903          - Preliminary seaice_growth.F clean-up, keeping test results strictly unchanged.
1904            The emphasis here was on improving readability (e.g. by trying to use meaningful
1905            variable names) and modularity (e.g. by adding arrays to store heff etc. updates).
1906        part 1.5:
1907          - revising the lab_sea experiment to make it a more useful (i.e. stable
1908            and representative of an actual model run). This was done by generating a
1909            (winter) pickup to start from, switching back the main experiment dynamic
1910            solver from evp to lsr, having one of the experiments use the free drift solution.
1911        part 2: seaice_growth.F revisions 1.76 to 1.85
1912          - Sorting out hard-coded constants that prevented heat and fresh water conservation.
1913          - Sorting out the various fields units and sign (set early on and reset at the end)
1914            to avoid numerous scalings/re-scalings. By v1.85 the basic unit for ice, heat and
1915            fresh water stock is 'effective ice meters', and >0 implies more ice/snow.
1916          - Using tendency terms arrays (d_HEFF* etc.) to alleviate remaining code locks,
1917            and simplifying logical expressions to further improve readibility.
1918        part 3: seaice_growth.F revisions 1.86 to 1.89
1919          - Re-organize the blocks of code more logically.
1920          - Merging the '_if.F' pieces that add something new.
1921    o pkg/thsice:
1922      - vectorize thsice_solve4temp and thsice_get_exf.
1923        Problem: thsice_solve4temp has an unvectorizable statement that
1924        might also be problematic for TAF
1925      - thsice_get_exf: add the ALLOW_BULK_LARGEYEAGER04 CPP-flag. This
1926        does not change the verifcation experiment, but will change all
1927        experiments that have this flag undefined (not tested in verification);
1928        a little reorganization to save a few 2D fields and recomputations
1929      - 1st step of revisiting thsice adjoint (major recomp. sorted out)
1930      - 2nd step:  fix some store dirs
1931        o seems to work somewhat, i.e. using ifort but not g77
1932        o likely cause are incomplete init. or recomputation
1933        o start verification/global_ocean.cs32x15/input_ad.thsice
1934    o pkg/obcs: add support for exch2
1935      - the position of the boundary and prescribed values are specified using
1936        a global domain with exch2 facets stacked
1937        - in x for N,S boundaries (like W2_mapIO=-1)
1938        - in y for E,W boundaries (so E,W boundaries do not overlap)
1939    o pkg/mdsio: add support for writing global sections with exch2
1940        file layout is as for obcs described above:
1941        - for x-z sections, facets are stacked in x (like W2_mapIO=-1)
1942        - for y-z sections, facets are stacked in y
1943    o pkg/thsice:
1944       - change a few routines for better vectorization: thsice_albedo.F,
1945         thsice_step_temp.F, and in thsice_calc_thickn.F. Results are
1946         not affected, but in particular the latter routine has changed
1947         dramatically (not necessarily easier to read now).
1948       - re-arrange calculation in THSICE_SOLVE4TEMP: move outside of i,j loops
1949       iteration loop and call to S/R THSICE_GET_BULKF & THSICE_GET_EXF.
1950    o verification/lab_sea:
1951      - overhaul of the forward model experiments. The main motivation
1952        for this revision is that lab_sea has proven quite fragile (when
1953        changing the sea-ice code, and switching platforms) to a point
1954        when failures were very hard to attribute to specific code problems.
1955      - the suspected reason for this fragility is noise amplification by evp so,
1956        to start with, we decided to replace evp with lsr in the main experiment.
1957      - the input.lsr experiment thus became obsolete and was removed.
1958      - it was replaced with the input.fd experiment that uses an
1959        analytical "free drift" solution as the ice velocity field.
1960      - Taken together, input (lsr), input.fd (free drift) and input.hb87 (evp)
1961        will hopefully allow us to discriminate problems due to dynamic solvers
1962        from problems due to the thermodynamic code. input.salt_plume (lsr) allows
1963        us to test additional options, along with the salt plume package.
1964      - Finally a pickup was generated (at the end of a one year run) to
1965        make the tests more representative of an actual model run. Previously
1966        the tests starting point was a 1m thickness of ice everywhere.
1967    o pkg/seaice:
1968      - introducing S\R seaice_freedrift.F that compute the
1969        analytical solution to an approximate ice momentum
1970        equation (i.e. the simple stress/coriolis balance).
1971      - define SEAICE_ALLOW_FREEDRIFT to trigger the computation
1972        of the free drift velocity field, and enable its use.
1973        To actually use the free drift solution as the model ice
1974        velocity field set SEAICEuseFREEDRIFT to .TRUE. in data.seaice.
1975    o move "useOASIS" from PARAMS.h to EEPARAMS.h and read it from "eedata"
1976    
1977    checkpoint62l (2010/10/04)
1978    o pkg/seaice:
1979      -fix the USE_ORIGINAL_SBI version (for variable freezing point);
1980      -use "celsius2K" in SEAICE_VARIABLE_FREEZING_POINT and in new
1981       version (with USE_ORIGINAL_SBI undef);
1982    o add hooks for new packages OASIS, the package will follow
1983      (hooks exclude the seaice pkg for now)
1984    o pkg/autodiff: ALLOW_AUTODIFF_WHTAPEIO
1985      Option to use mdsio_read_whalos.F/mdsio_write_whalos.F,
1986      rather than mdsio_readvector.F/mdsio_writevector.F, within
1987      adread_adwrite.F to read/write adjoint-related tapes to disk.
1988    o eesupp and pkg/mdsio: ALLOW_WHIO
1989      Option to write/read 2D fields to files including tiles halos.
1990      The main purpose is for adjoint related "tape I/O".
1991      The secondary purpose is for debugging phases.
1992      A word on those rather specifically intended purposes.
1993      The code was meant to be stripped down to the bare minimum.
1994      Typically, there is a unique and basic mapping to the global
1995      buffer (tile by tile, then proc by proc, then level by level), and
1996      byteswaps and meta-files are omitted. Indeed the (*_WH*) code is not
1997      meant to generate user friendly outputs of various shapes and forms.
1998      Rather it is intended, for the knowledgeabale developers,
1999      to be largely independent of the many mdsio options, to allow
2000      outputs of tiles+halos in debugging phases and in adjoint runs,
2001      and to allow some flexibility in tuning (adoint) I/O depending on each
2002      file system behavior. With regard to tuning, most of the potential knobs
2003      (to leave files open, to allocate the I/O indep. of usesinglecpuio,
2004      to specify directories, to specify the typical size of I/O calls, etc.)
2005      are not yet included, and will be added if they prove useful.
2006    o pkg/seaice:
2007       fix uninitialised arrays in USE_ORIGINAL_SBI version of seaice_solve4temp.F
2008    o pkg/seaice:
2009       new S/R seaice_solve4temp.F: this is the merged version of Ian Fenty
2010       code (seaice_budget_ice_if.F) which enable to recover old standard
2011       code (seaice_budget_ice.F) when option USE_ORIGINAL_SBI is defined.
2012       temporary: add "#define USE_ORIGINAL_SBI" at the top of seaice_solve4temp.F.
2013    o model/src (rStar):
2014       use simple average (not area weighted) of rStarFac at U,V point when using
2015       vectorInvariant and selectKEscheme=1,3 (consistent with mom. vertical advection)
2016       update output of exp. fizhi-cs-32x32x40 and fizhi-cs-aqualev20.
2017    
2018    checkpoint62k (2010/09/17)
2019    o adjoint
2020       * changed verification/global_ocean.cs32x15 ; adjoint now tests
2021         Adams-Bashforth 3 + NLFS + RSTAR
2022       * some more modifs required for ECCO-GODAE v4
2023    o pkg/seaice
2024       add SEAICE_AGE_VOL option to use volume instead of area for
2025       integrating SEAICE_AGE
2026    o model/src:
2027       first check-in of sigma & hybrid-sigma coordinate code ; also includes
2028       non-linear free-surface parts ; but pressure-gradient not yet coded.
2029    o pkg/ptracers:
2030       option for ptracer to convert Salt Relax into additional EmP.
2031        tested in exp. global_ocean.90x40x15.dwnslp (update output)
2032    
2033    checkpoint62j (2010/08/25)
2034    o pkg/ggl90:
2035       other minor changes: remove 3-D temp array gTKE (+ add argument myIter)
2036    o pkg/dic: car_flux.F, phos_flux.F
2037      - reduce number of exp-calls in order to improve performance
2038      - clean up a little (replace fields by their macros, etc., fix
2039        typo in CPP-flag)
2040    o pkg/ggl90: minor changes
2041      - GGL90diffKrS was removed --> always use GGL90diffKr
2042      - GGL90viscAr was removed --> replaced with GGL90viscArU, GGL90viscArV
2043      - hack of mxlMaxFlag=2 --> ensure mixing between first and second level
2044        (commented out for now)
2045      - change in max/min operations to ensure that smoothing is ok
2046      - smoothing of GGL90viscAr was moved to ggl90_calc.F (as done for GGL90diffKr)
2047      - always use diffKrNrT as background profile (i.e. never use diffKr field)
2048    o pkg/cfc: bug fix, AREA(i,j,1,bi,bj) -> AREA(i,j,bi,bj)
2049    o pkg/dic:
2050      - model/src/impldiff.F: if TARGET_NEC_SX, extend loop ranges for better
2051        vectorization
2052      - small bug fix in insol for the unlikely case of a cartesian grid
2053      - towards vectorizing the dic package: bio_export.F, car_flux.F, phos_flux.F
2054        + now vectorize, which also removes adjoint recomputations;
2055        + replace integer maksp1 by _RL maskp1
2056        + replace a**x by exp(x*log(a)) in phos_flux.F for speed
2057    
2058    checkpoint62i (2010/07/21)
2059    o pkg/flt:
2060      - with OBCS: stop floats which enter the OB region
2061    o model/src:
2062      - use tempVertAdvScheme & saltVertAdvScheme (instead of horizontal ones)
2063        for implicit vertical advection.
2064    o pkg/seaice:
2065     - account for melting in seaice age evolution.
2066     - remove double counting of seaice ridging effect on seaice age.
2067    
2068    checkpoint62h (2010/06/18)
2069    o pkg/exch2:
2070     - remove exch2_*xy_rx files: call was replaced with exch2_*3d_rx(myNz=1).
2071    o tools/genmake2
2072      - remove "-pdefault" option: redundant with the use of "packages.conf";
2073      - remove file pkg/pkg_default : set the default as a pkg group
2074        ("default_pkg_list") defined in pkg/pkg_groups;
2075      - fix for case pkg/pkg_depend is missing (was hanging before);
2076      - add option "-pgroups" to specify a different pkg_groups than the default.
2077    o verification/adjustment.cs-32x32x1:
2078       add a "minimal" set-up test (code_min & input_min) which only compiles
2079       eesupp/src and the 2 pkgs (exch2 & debug) which don't need model/src & inc.
2080    o tools/genmake2
2081      - extend pkg_depend rules to model & eesupp (e.g., if model depend on [pkg]))
2082      - fix details of checking for mnc & profile pkg when NetCDF is unavailable.
2083    o pkg/exf: merge exf_bulk_largeyeager04 into exf_bulkformulae because these
2084      files are nearly the same anyway.
2085      Step 1: make exf_bulkformulae look like exf_bulk_largeyeager04:
2086       - redefinition of tau(i,i) (by a factor of ustar)
2087       - 1./exf(Const/T) -> exf(-Const/T) (big change in the results)
2088       - replace rhonil by rhoConstFresh in computation of evap (bug fix)
2089       - replace u/vstress=tau*rd*ws*cw by tau*rd*u/vwind (changes results)
2090       - replace
2091         rd(i,j)= rdn(i,j)/(exf_one - rdn(i,j)/karman*psimh )
2092         shn    = sh(i,j,bi,bj)*rd(i,j)/rdn(i,j)
2093         by
2094         shn    = sh(i,j,bi,bj)/(exf_one - rdn(i,j)/karman*psimh )
2095         (changes results)
2096       -> exf_bulkformulae v1.22,
2097          update verification experiments lab_sea, offline_exf_seaice, seaice_obcs
2098          (lab_sea: output.hb87.txt 1.11, output.lsr.txt 1.25, output.salt_plume.txt 1.13,
2099                    output.txt 1.63
2100           offline_exf_seaice: output.seaicetd.txt 1.7
2101           seaice_obcs: output.txt 1.10)
2102      Step 2: do the actual merge and remove exf_bulk_largeyeager04.F
2103       -> exf_bulkformulae v1.23,
2104          unfortunately requires updating lab_sea.salt_plume (6 matching digits),
2105          and global_ocean.cs32x15.icedyn (only 11 matching digits)
2106      Also update output_adm of exp. lab_sea (all 4) and offline_exf_seaice.
2107    o adjoint of exch-1:
2108     - pass high-level EXCH S/R through TAF (eesupp/src/exch_ad_diff.list)
2109       (note: was already like this when using EXCH-2) and remove flow dir
2110       and hand-written AD version of high-level EXCH S/R (pkg/autodiff);
2111     - provide flow-dir for low-level exch1 S/R (eesupp/src/exch1_ad.flow);
2112     - update pkg/exch2 diff list.
2113    
2114    checkpoint62g (2010/05/19)
2115    o eesupp/src (exch-1):
2116     - split exch_rx.F into Forward S/R (exch1_rx.F) and Adjoint S/R (exch1_rx_ad.F)
2117       and remove argument "simulationMode"; same thing for all exch_*rx_cube.F
2118       (renamed to exch1_*rx_cube.F).
2119     - change accordingly exch_*_rx.template and AD version in pkg/autodiff
2120       to call new exch1 S/R ; update Makefile and .cvsignore.
2121     - replace call to exch2_xy_rx S/R with exch2_*3d_rx(myNz=1) (will remove
2122       exch2_xy_rx later)
2123      Note: after updating your code, need to run "make clean" in eesupp/src
2124    o test experiment bottom_ctrl_5x5:
2125       new output_adm.txt with fewer grdchk & less monitor output.
2126    o model/src:
2127      remove the call to ini_cori in initialise_varia.F (just keep the usual one
2128       in initialise_fixed.F). More consistent with coriolis & horizontal grid
2129       beeing treated in the same way (ini_grid is not called a 2nd time).
2130    o pkg/exf:
2131      - rewrite exf_bulk_largeyeager04.F for better vectorization, changes
2132      global_ocean.cs32x15/input.icedyn (11 digits of agreement), updated
2133      - fix adjoint (used worked for ALLOW_ATM_WIND defined, works for this now)
2134      - cosmetic changes to exf_bulkformulae.F to make it look more like
2135        exf_bulk_largeyeager04.F
2136    o eesupp/src (exch-1):
2137      - Fix AD EXCH code for 2-D domain special cases (Nx=1 or Ny=1).
2138      - Separate buffer filling and MPI sending: allow EXCH-1 to work for local
2139        array (non-shared) when using MPI+MTH. Also reduces number of BARRIER
2140        (even without using MPI).
2141      - Message mode: move RecvAck setting (indicator of buffer being ready)
2142        from send_put to recv_get S/R (was useless before, but not sure if
2143        it's much more useful now);
2144      - Switch the order of sync: MPI-proc 1rst and then threads;
2145      - take out spin-waiting code (#undef EXCH_USE_SPINNING), use BARRIER instead.
2146      - fix AD code for communication mode ='get' (but not used).
2147    o model/src:
2148      initialise dPhiHydX,dPhiHydY inside calc_grad_phi_hyd.F (so that TAF does
2149      not drop it in S/R mddynamics, producing NaN in hs94.1x64x5 AD-test exp).
2150    o utils/matlab/rdmnc.m: adapt to be able to use the generic matlab netcdf API
2151    o pkg/ctrl: require a specific set of control variables and exf-flags for
2152      adjoint of seaice (stop in ctrl_check.F if conditions are not satisfied)
2153    o model/src:
2154     a) 1rst version of a new driver S/R to turn-off output freq and flags after the
2155       1rst forward sweep, to avoid over-writing output files during recomputations
2156       recomputations (& grdchk); called from cost_final.F (& ctrl_init_ctrlvar.F ?)
2157     b) 2nd version:
2158      - add specific pkg S/R for seaice & ptracers (called from S/R TURNOFF_MODEL_IO);
2159      - switch-off more output flags (exf_monFreq, chkPtFreq, dumpInitAndLast,
2160         writePickupAtEnd) + seaice & ptracers output;
2161      - do not switch off MNC flags (otherwise, won't get admonitor netcdf file)
2162    o model/src:
2163      - new S/R rotate_uv2en_rl (..._rs) that rotates vector fields.
2164    o pkg/exch2:
2165      - remove "simulationMode" from arg. list of S/R EXCH2_RX1,2_CUBE ;
2166      - add argument "signOption" to EXCH2_RX1_CUBE (will be needed for SM exch).
2167    o pkg/autodiff & exch2:
2168      process exch_uv_agrid_3d_rx.f & exch2_uv_agrid_3d_rx.f through TAF
2169      (for now, only if ALLOW_EXCH2 is defined).
2170    o pkg/autodiff:
2171      - include PACKAGES_CONFIG.h in exch*ad.flow & exch*ad.F
2172        (not supposed to be in CPP_OPTIONS.h) to get ALLOW_EXCH2 defined correctly.
2173       + clean-up comments (_RS is not always real*4)
2174      - fix bug in ADEXCH_UV_3D_RX (without EXCH2, was calling the forward exch S/R)
2175      - add a stop in ADEXCH_UV_AGRID_3D_RX if trying to use it with EXCH2:
2176        was calling a forward exch2, which is wrong ; used in SEAICE & EXF pkgs.
2177    o testreport (AD-tests):
2178      no longer link files from dir "../input" (1rst link files from
2179      "../input_ad.[xx]" if secondary test "xx" and then from "../input_ad")
2180    
2181    checkpoint62f (2010/04/29)
2182    o model/src/the_main_loop.F:
2183      adjust store directives for seaice evp and multicategory according to
2184      pkg/ecco/the_main_loop.F
2185    o adjoint:
2186      global_sum_ad was incomplete (noted many times by many people ;)
2187      nice description by Jean U. as follows:
2188      * allreduce(var) in global_sum.F can be interpreted as
2189        reduce(sum) followed by broadcast of sum.
2190      * The adjoint of that is
2191        sum(adjoint) followed by broadcast(summed adjoint value)
2192        or in other words, allreduce(sum, adjoint vars)
2193      We were missing the sum(adjoint)!
2194      Benign, except(!) for "global" scalars appearing in tile loops (bi,bj)
2195      (noted by J.M. Campin, e.g., in cost_ssh_mean, variable offset).
2196      The fix should produce 16-digit accuracy between
2197      single-CPU multi-tile (e.g. nSx=2, nPx=1) and
2198      multi-CPU single-tile (e.g. nSx=1, nPx-2)
2199      We'll probably change this yet again shortly
2200    o eesupp/src:
2201      - fix global_sum_r4 (wrong from previous modif in Jun 2009; ever used ?)
2202    o pkg/icefront
2203      - ALLOW_SUBGLACIAL_RUNOFF option adds capability for time-evolving
2204        specification of addmass array based on a 2D field, which is added
2205        at bottommost wet level at each horizontal location.
2206    o model/src:
2207     horizontal grid initialisation (other than curvilinear): add code for Exch2 IO
2208     layout; (not always compatible with delX,delY setting; commented out for now).
2209    o pkg/exch2:
2210     change tile to processor setting (case nSy*nPy > 1): allows default model mapping
2211     (myX and myYGlobalLow) to be used for simple (1 facet, no blank tile) config.
2212    
2213    checkpoint62e (2010/04/15)
2214    o pkg/obcs:
2215      - fix wrong index in OBCS_SPONGE_V for Eastern-OB (reported by David Hebert).
2216    o pkg/dic:
2217      -fix bug in fe_chem.F for multi-tile (nSx*nSy > 1) set-up;
2218        (note: not presently tested in any forward verification exp.)
2219       update tutorial_global_oce_biogeo AD output file.
2220    o pkg/exf:
2221      - account for the variation of albedo as a function of zenith angle
2222        by defining ALLOW_ZENITHANGLE in EXF_OPTIONS.h
2223    o build_options:
2224     - rename "linux_ia64_ifort+mpi_ice_nas" to "linux_amd64_ifort+mpi_ice_nas"
2225    o pkg/dic:
2226      change DIC atmos-CO2 box (method 3, dic_int1=3) initialisation & restart:
2227      - use binary pickup file for restart;
2228      - initialise atmos-CO2 box from dic_pCO2 parameter;
2229      - fix multi-threaded.
2230    o pkg/rbcs:
2231     - clean-up RBCS code: add RBCS_OPTIONS.h file ; fix multi-threaded ;
2232       change (+ fix IO calls) type of array RBC_mask from _RL to _RS.
2233     - add RBCS to exp4 passive tracer 01 (rbcs was previously untested)
2234       and update output.txt
2235    o pkg/kpp:
2236     - add diagnostics for KPP non-local flux of Temp, Salinity and pTracers;
2237     - change diagnostic of KPP non-local term: output average of KPPghat*KPPdiffKzS
2238       (= ratio of KPP non-local (salt) flux relative to surface-flux) when
2239       using pkg/timeave & pkg/diagnostics (diag 'KPPghatK' replaces 'KPPghat ');
2240     - change pkg/offline to read-in average KPPghat*KPPdiffKzS from file
2241       KPP_ghatKFile (instead of the average of KPPghat from file KPP_ghatFile).
2242    o pkg/offline:
2243      fix bug in S/R OFFLINE_FIELDS_LOAD regarding surfaceForcing conversion factor
2244      (bug was added in version 1.10 on 2007-08-23).
2245    o pkg/offline:
2246      - no need to specify periodicExternalForcing, etc ... to use offline pack
2247      - offline input files no longer just single prec --> parameter offlineLoadPrec
2248    o verification/lab_sea:
2249      change AD test to multi-tile setup and update all 4 AD output.
2250      NOTE: while cost function values remain very similar,
2251      gradients are very different, although gradient checks are self-consistent
2252      Should try to get to the bottom of this (cost function summation order?)
2253    o pkg/dic:
2254      in carbon_chem.F, replace log10 (AUTODIFF) with explicit form to avoid
2255      a weakness of TAF that drops part of double precision in log10 derivative.
2256      <= changes removed since problem has been fixed in current TAF version 1.9.71
2257      update AD output of exp. tutorial_dic_adjoffline & tutorial_global_oce_biogeo.
2258    o pkg/ecco:
2259      add missing "_d 0" in cost_readers.F, cost_readtopex.F & cost_readtopexmean.F
2260      update all 4 lab_sea AD output.
2261    
2262    checkpoint62d (2010/03/22)
2263    o build_options:
2264      remove '-r8' (and '-i4') from linux_*pgf and linux_*ifort optfiles.
2265    o remove unbalanced quote (single or double) in commented line of source code
2266      (may cause some warning with some preprocessor/makedepend versions).
2267    o pkg/seaice:
2268      fix seaice_model.F for adjoint (gael) and update AD results of experiments
2269       lab_sea (std + evp + noseaicedyn) and offline_exf_seaice.
2270    o testreport:
2271      add option '-runonly' (short: '-ro') to just do the run part (without make).
2272    o eesupp: remove JAM communication code (obsolete).
2273    o add option to genmake2 & testreport to switch "_RS" type to "real*4"
2274      (if allowed in CPP_EEOPTIONS.h); update default CPP_EEOPTIONS.h and return
2275      to default CPP_EEOPTIONS.h for exp. inverted_barometer & solid-body.cs-32x32x1
2276      (update also the output).
2277    
2278    checkpoint62c (2010/03/02)
2279    o tools/build_options :
2280       move (some) old optfiles from build_options/ to build_options/unsupported/
2281    o model/src and pkg/exf
2282       surface relaxation -- separating data and data.exf options
2283       The point is to ensure that we specify the surface relaxation
2284       either in data or in data.exf (but not half and half) and to
2285       avoid an accidental relaxation to 0 (which happened if a time
2286       scale was specified but the file name was left empty)
2287    o model/src model/inc and pkg/mom_common
2288       ALLOW_3D_VISCAH/ALLOW_3D_VISCA4 => 3D specification of Viscosity
2289       => addition to the viscosity field as computed by others schemes
2290    o tools/build_options:
2291      - rename "_generic_mpi" -> "+mpi_generic" (like other "+mpi" optfile)
2292        but keep the former optfile for few weeks for smooth transition
2293    o pkg/ecco
2294      - allow user defined cost function contributions
2295         CPP: ALLOW_USERCOST_CONTRIBUTION
2296         USAGE: compute contributions in cost_usercost_all.F
2297      - note: this is identical to what ALLOW_GENCOST_CONTRIBUTION once was.
2298          the two options are complementary.
2299    o pkg/smooth
2300      - migration from contrib to the main repository
2301    
2302    checkpoint62b (2010/01/26)
2303    o pkg/monitor:
2304      - change back mon_printstats_rl.F & mon_stats_rl.F and add a stop
2305        (in case someone forgot to update customized pieces of code)
2306    o nonHydrostatic:
2307      - add Non-hydrostatic free-surface form (selectNHfreeSurf=1)(not fully tested);
2308      - add a simple 2-D experiment (short_surf_wave) to test it.
2309    o pkg/icefront:
2310       adding the shell of, and the hooks to, a new package that
2311       will model melting and freezing of vertical glacier ice fronts
2312    o momentum:
2313      add diagnostics of momentum tendency from Hydrostatic pressure gradient
2314       (without surf.pressure term: would need a 2nd filling since implicit term).
2315    o add 3 "_d 0"s so that fizhi compiles with xlf on iblade, and replace
2316      two " &end" by " &" (in fizhi-cs-*) because S/R NML_SET_TERMINATOR
2317      cannot deal with the former
2318    o cleaning:
2319      - remove all (except OpenAD) old TLM output from results_ad dirs.
2320      - remove unused S/R (MDSWRITEMETA, DIAGNOSTICS_ADD2LIST, old DFILE IO S/R)
2321      - comment out maskH definition (replaced by maskInC)
2322    o pkg/monitor:
2323      - change mon_printstats_rl.F & mon_stats_rl.F (were similar to mon_writestats_rl
2324        & mon_calc_stats_rl) to be the RL equivalent of mon_printstats_rs & mon_stats_rs.
2325    
2326    checkpoint62a (2010/01/15)
2327    o model/src:
2328      - bottom pressure diagnostic: correct for r* (when nonlinFreeSurf >= 4)
2329    o pkg/diagnostics:
2330      - add optional level number diagnostics (i.e., level number to be define
2331        explictly with S/R DIAGNOSTICS_SETKLEV) with parser-code(10)="X".
2332      - strictly check for valid parser-code(10) ;
2333      - check if adding diag to the list from the right place.
2334    o pkg/longstep:
2335      - change parameters and fix tracer conservation with rstar/nonlinear free surface
2336    o diagnostics:
2337     - in all pkgs, replace remaining calls to old S/R DIAGNOSTICS_ADD2LIST with newer
2338       S/R DIAGNOSTICS_ADDTOLIST ; fix seaice VICE diagnostics.
2339    o pkg/diagnostics:
2340     - Add option for writing vertical integral (sum of selected levels) of an output
2341        field instead of writing output field levels. Activate this option on a per
2342        output-file basis, by setting the 2nd character of fileflag to 'I'.
2343     - Add field-specific information relative to level integral in 3rd postion
2344        of parser diagnostics code (gdiag): " "=cumulate levels, "R"=integrate
2345        vertically (x level-thickness x hFac), "r"=same but without hFac.
2346    o do_the_model_io:
2347      - pass end-of-model-run flag as argument, from forward_step to diagnostics_write:
2348        in case useSIGREG, will write (averaged) diagnostics (if dumpAtLast) before
2349        writing pickups and stopping.
2350    o pkg/diagnostics (for now, only with mdsio):
2351      - write time information to meta file (and modify accordingly rdmds.m) :
2352        time-averaged diagnostics output: write starting and ending time of the
2353        time-averaging interval ; snap-shot diagnostics output remains unchanged;
2354    o pkg/timeave:
2355      - S/R TIMEAVE_NORMALIZ: change size of cumulated-time array (was previously
2356        always Nr), now assumed to be equal to number of levels of averaged field;
2357        only used for DIC_COST monthly mean arrays: this fixes dic_aver_final.F
2358    o pkg/sbo:
2359      - fix ocean bottom pressure global-average & 2-D time-ave output (was
2360        neither initialised nor filled).
2361      - add starting iteration in suffix of global-average output file
2362        (to avoid over-writing the file after a restart)
2363      - use standard MDSIO pkg S/R instead of SBO_WRITEVECTOR (fix byte-swap Pb).
2364    o time-average:
2365      - use simple cumulative-time array (no k index) in all pkgs: {PKG}_timeAve(bi,bj)
2366        (pkgs: aim_v23, bulk_force, dic, gmredi, kpp, land, ocn_compon_interf,
2367         ggl90, my82, opps, pp81, ptracers, sbo, seaice, shelfice, thsice)
2368        this fix DIC_COST cumulative-time array (previously: bi,bj,k)
2369      - fix 1rst call (nIter0) snap-shot output and accumulation (pkg/shelfice)
2370      - fix missing accumulation for pkg/opps.
2371      - cumulate fields only if doing time-ave output ({PKG}_taveFreq > 0)
2372         (pkgs: ptracers, kpp, ocn_compon_interf, ggl90, my82, pp81);
2373      - fix initialisation of time-ave vars and do only full time-step increment
2374        (i.e.: no first & last "half time-step") (pkgs: ggl90, my82, opps, pp81);
2375    o pkg/layers:
2376      - use standard RW pkg S/R to write the output
2377        and remove local write_fld version (which had a problem).
2378      - use simple cumulative-time array (no level index) to fix time-ave S/R calls.
2379      - fix LAYERS_CALC argument list.
2380    o pkg/timeave:
2381      - store cumulative-time in a simple tiled array (drop the level index)
2382      - add new S/R (TIMEAVE_NORMALIZE) which uses simple cumulative-time array.
2383    o pkg/ocn,aim_compon_interf
2384      - changes for multi-threaded coupled run. (tested with ifort-11 on danton)
2385    
2386    checkpoint62  (2009/12/23)
2387    o switch on useOBCSbalance in tutorial_plume_on_slope exp. and update output.
2388        (was not previously tested in any other exp.)
2389    o pkg/monitor:
2390      - clean-up _RL/_RS version: add specific S/R for statistics with mask & volume:
2391        mon_writestats_rl/s,F mon_calc_stats_rl/s.F ; will keep the old one
2392        (mon_printstats_rl/s,F mon_stats_rl/s.F) just for bare statistics.
2393      - use hFac & 2-D mask (instead of 3-D mask + hFac in previous mon_stats_rl.F).
2394      - change del2 calculation.
2395      - use interior masks (instead of maskH, <- to be remove).
2396      - shorter monitor suffix for forcing stats ("forcing" instead of "extforcing").
2397    o mask & obcs:
2398      - define 2-D "interior" masks (i.e., zero beyond OB) at 3 locations (C, W & S).
2399      - move global area computation from ini_masks_etc.F to ini_linear_phisurf.F
2400        (called after packages_init_fixed)
2401    o pkg/obcs:
2402      - move bi,bj loops into obcs_calc, so obcs_prescribe_read is called only once.
2403        Fixes bug in obcs+exf with nSx*nSy.GT.1
2404      - fix multi-tile handling in obcs balance code
2405    o nonHydrostatic:
2406      - Implement AB-3 for non-hydrostatic vertical momentum ;
2407        (change ordering of var. stored in pickup file when using NH)
2408      - move NH code from solve_for_pressure.F to 2 new S/R: PRE_CG3D & POST_CG3D.
2409      - add 2-D field to store Hydrostatic Surface Pressure adjusment from cg3d_x
2410        (in prep. for new NH free surface form).
2411    o pkg/obcs:
2412      add files & OB-variables for wVel (Non-Hydrostatic) with useOBCSprescribe
2413    o model/src:
2414      fix 2-D solver initialisation for deep-atmosphere (p-coord) with topography
2415    
2416    checkpoint61z (2009/12/01)
2417    o nonHydrostatic:
2418      Fix missing vertical flux of vert. momentum near surface (k=1). This fixes
2419        a spurious source of energy in simple baroclinic adjusment test case.
2420      Update all non-hydrostatic exp output.
2421    o model/src (3-d solver):
2422      Change again 3-D solver free-surface RHS term when exactConserv=T:
2423        simpler, consistent with exactConserv, and works with implicDiv2Dflow < 1
2424        (which was not the case with previous formulation).
2425      To recover previous version, just reset "oldFreeSurfTerm" to previous value.
2426      Affects results of exp. global_ocean.cs32x15.viscA4 & hs94.cs-32x32x5.impIGW.
2427    o nonHydrostatic:
2428      - compatible with implicDiv2Dflow < 1 ; + implement implicit factor
2429        for Non-Hydrostatic pressure gradient (similar to implicSurfPress).
2430      - change 3-D solver to work with r* (for now, only with linear free-surf.)
2431      - add few debug diagnostics (cg3d_x, residual)
2432    o model/src:
2433      fix missing EmPmR in 3-D solver RHS (was in cg2d_b but missing in cg3d_b).
2434        update output of exp. global_ocean.cs32x15.viscA4
2435    o update output of exp. global_ocean.cs32x15.icedyn after removing
2436      #define SEAICE_OLD_AND_BAD_DISCRETIZATION from SEAICE_OPTIONS.h
2437    o add entry points for Gianmaria's Nesting pkgs (from Contrib/nesting_sannino)
2438    o mnc: add horizontal grid coordinates (XC,YC) and (XG,YG) to netcdf output
2439      for complex grids, for now only to "state", "adstate", "adexf", "adseaice"
2440    o model: add Christopher Wolfe's implemetation of the single reduction cg2d
2441      (d'Azevedo, Eijkhout, and Romine, 1999) with CPP-flag ALLOW_SRCG and
2442      runtime flag useSRCGSolver. Modify verification experiment global_with_exf
2443      to test this code
2444    o pkg/cd_code:
2445      Change defaut D-grid time-stepping to get the same for D-grid momentum as for
2446       C-grid momentum. D-grid velocity used to be stepped forward in time with
2447       Adams-Bashforth only on surface pressure term. Tests show that using AB on
2448       D-grid coriolis term improves stability (as expected from CD-scheme paper).
2449      To reproduce old results, add 2 options (in CD_CODE_OPTIONS.h).
2450      Update results of exp: global_with_exf (x2), ideal_2D_oce, isomip (x2),
2451       lab_sea (3 Fwd +3 AD), natl_box (x2), tutorial_global_oce_biogeo (Fwd+AD),
2452       tutorial_global_oce_latlon, tutorial_global_oce_optim & tutorial_tracer_adjsens.
2453      Keep old results by adding CD_CODE_OPTIONS.h in exp: cfc_example, exp2,
2454           global_ocean.90x40x15(+AD), global_ocean_ebm(+AD) and OpenAD.
2455    o pkg/obcs:
2456     - fix bug in initialisation (broken since Oct 1rst modification)
2457       for useOBCSprescribe without useEXF.
2458    
2459    checkpoint61y (2009/11/15)
2460    o pkg/seaice
2461     - change (once again) the discretization for the evp solver: rather than
2462       squaring the averages of strain rates, average the squares to give
2463       a better approximation to VP behavior (in simple test); this breaks
2464       verification experiments that use EVP (lab_sea and lab_sea.hb87)
2465        --> update outputs
2466    o add CPP-flag (in mom_calc_visc.F) and TAF directive (in gmredi_slope_limit)
2467      to improve vectorization of adjoint code on TARGET_NEC_SX
2468    o verification/vermix:
2469      - change vermix to a more "classical" 1d column with high vertical
2470        resolution, seasonal heat flux forcing and constant wind forcing
2471        --> update outputs
2472    o pkg/seaice
2473     - fix diagnostics of principal stress components for EVP
2474     - add optional diagnostics of non-linear convergence for LSOR solver
2475     - make maximum zeta a runtime parameter
2476    o model/src (3-d solver):
2477      Undo modif from Dec 12, 2005 (solve_for_pressure.F cvs version v.49),
2478       which consisted in removing the Surf. Non-Hydrostatic pressure from the
2479       whole column and adding it to Eta (inspired from Casualli, 1999):
2480       Only affects 3-D solver initial guess and only if using ExactConserv,
2481       but tests did show a degradation of solver convergence. For this reason,
2482       decide to disable this piece of code.
2483       to recover previous version, just set zeroPsNH = exactConserv (line 78).
2484      Update output of exp. global_ocean.cs32x15.viscA4 & hs94.cs-32x32x5.impIGW
2485    o pkg/ggl90:
2486     - fix previous modif (unfortunatly has not been documented here).
2487    o pkg/seaice/autodiff:
2488     - add CPP flag to include clipping of zeta in EVP code;
2489       although clipping of zeta is not necessary for EVP and not recommended
2490       it was done by default, now clipping is disabled by default
2491     - modify computation and store zetaC/Z in seaice_evp for TAF
2492     - add CPP-flag SEAICE_ALLOW_CLIPVELS (undefined by default)
2493     - change seaice_calc_viscosities/strainrates for better
2494       vectorization after AD by TAF
2495     - rearrange common blocks in SEAICE.h once again for easier dumps of
2496       adjoint output, adjust adcommon.h and g_common.h
2497     - change flux form of default advection scheme for better vectorization
2498       of adjoint code
2499     - modify lab_sea/input.lsr to test the flux form of default advection
2500       scheme
2501    o autodiff: fix seaice fields in g_common.h (left over from 3 to 1 level
2502      transition in checkpoint61r)
2503    
2504    checkpoint61x (2009/10/19)
2505    o adjoint: adding two new verification experiments
2506      * tutorial_global_biogeo: an online dic sensitivity experiment
2507        (work with G. Forget)
2508      * tutorial_dic_adjoffline: an offline dic sensitivity experiment
2509        (an update of the Dutkiewicz et al., 2006 paper)
2510      Both use the same CO2FLUX cost function, but different controls
2511      Gradient checks look good, but some recomp. could still be traightened out
2512      Should add xx_dic control variable to test at some point
2513    o model/src:
2514      add run-time parameters to check and/or mask initial Temp & Salt
2515    o pkg/ptracers:
2516      apply zonal filter (if used) to all passive tracers
2517    
2518    checkpoint61w (2009/10/12)
2519    o adjoint:
2520      * update and finish work on adjoint of dic package (G. Forget)
2521      * start adjoint of offline package
2522      * bug fix for cube-sphere TLM code (active_file_g.F)
2523    o tutorial_global_oce_optim:
2524      now tested with 4 tiles (change data.grdchk and update output_adm.txt)
2525      and add SIZE.h_mpi for MPI testing
2526    o pkg autodiff
2527     - fix bug in autodiff_restore
2528     - make genmake2 remove comments and empty lines from ad_input_code.f in
2529       order to reduce file size (new script file remove_comments_sed)
2530    o allows to specify vertical profile of vertical viscosity (viscArNr)
2531    o pkg autodiff
2532      autodiff_ini_model_io: comment out writing of grid information to netcdf
2533      files, because at this time the grid fields are a bunch of zeros
2534      (this is analogous to ini_mnc_vars.F)
2535    o pkg seaice/autodiff:
2536     left-over from removing the 3-time-level fields:
2537     - small rearrangement of common blocks (SEAICE.h)
2538     - fix field declaration in order to get meaningful output in
2539       adseaice.*.nc (adcommon.h)
2540    o pkg obcs:
2541     - go through NH code only if nonHydrostatic=T
2542     - fix restart for Orlanski (Hydrostatic; still to fix NH+Orlanski restart)
2543     - move call to OBCS_CALC before SEAICE_MODEL which needs seaice-obc fields
2544       => Update output of experiment seaice_obcs
2545     - useOBCSbalance: code is wrong with multi-tile / proc: add a stop.
2546     - fix NH+Orlanski restart (add wvel OBC value in pickup file)
2547     - fix restart for useOBCSprescribe + useEXF
2548    o pkg ctrl
2549     - make obcs as control parameter work also with useSingleCPUio
2550     - replace a few sny and snx by Ny and Nx to be consistent with
2551       ctrl_set_globfld_x/yz.F
2552    o pkg seaice
2553     - re-introduce global field frWtrAtm for the case of
2554       ALLOW_MEAN_SFLUX_COST_CONTRIBUTION defined (SEAICE.h, seaice_growth.F)
2555     - catch the case of an empty filename in seaice_cost_init_fixed.F
2556    o pkg ecco:
2557     - small bug fixes in the_main_loop
2558      . fix order of monitor arguments
2559      . change SEAICE_MULTILEVEL to SEAICE_MULTICATEGORY
2560      . move include DYNVARS.h up outside the ALLOW_AUTODIFF_TAMC block so
2561        that ALLOW_ECCO_FORWARD_RUN works with NONLIN_FRSURF
2562     - replace cos(yc*deg2rad) by _rA in cost_mean_heat/saltflux.F, fix the
2563       imbalance diagnostics for wmean_h/sflux = 0
2564     - add actual values to f_obcsn/s/w/e in ecco_cost_final.F
2565     - catch the case of empty filenames in ecco_cost_init_fixed.F
2566       and ecco_readparms.F
2567     - fix the logic of wsalt=0.and.wsalt2=0 to wsalt=0.or.wsalt2=0 (and theta)
2568       to make this statement meaningfull in ecco_cost_weights.F
2569    o pkg zonal_filt:
2570      - change ZONAL_FILTER S/R interface (allows to filter 2-D fields)
2571      - when using rStar, filter uVel*hFacW instead of uVel
2572       (tested without topography: fix a Pb of growing instability with NLFS)
2573    o pkg/aim/thsice:
2574     -Add capacity to read a Q-Flux to be applied in slab-mixed layer thsice_slab_ocean.F
2575      (works as SST restoring)
2576    o pkg/thsice:
2577     -add specific parameter for salt restoring in slab mixed-layer
2578       (by default equal to the temperature restoring)
2579    
2580    checkpoint61v (2009/09/21)
2581    o pkg/kpp:
2582     -add double diffusive contributions as a hack, turned off by default
2583      for now, and the code can be excluded with a CPP-flag
2584      EXCLUDE_KPP_DOUBLEDIFF just as EXCLUDE_KPP_SHEAR_MIX
2585     -add a verification experiments to "vermix" to test this code
2586    o pkg/mom_common:
2587      Move computation of length scales to mom_init_fixed.F (avoid recomputation
2588      at each time-steps*levels).
2589    o pkg/layers:
2590      Created a new package for computing volume fluxes in temperature or
2591      [not yet implemented] density layers, e.g. for calculating residual
2592      overturning circulations.
2593    o pkg/diagnostics:
2594      implement a RS type version for the set of DIAGNOSTICS-FILL subroutines
2595    o fix few RS/RL type mismatch (check with ifort 11.1 "-warn all" option)
2596    o pkg/mdsio (& pkg/rw): rework high level S/R interface:
2597      To avoid mixing type (RS/RL) of input/output array argument,
2598      replace single mixed-type array with a pair from each type (RS/RL).
2599    o setting pickupSuff force to start from a pickup (even if nIter0=0): this
2600      is now implemented for all pkgs (previously only done for the main pickup)
2601    
2602    checkpoint61u (2009/08/25)
2603    o pkg/obcs:
2604      - change OB?eta from _RS to _RL and put them into a separate commen block
2605      - add code to read OB?eta from a file via obcs_prescribe_read: the code
2606        compiles and does not destroy any other experiments, the data is read
2607        properly, but the code is not tested in actual applications
2608    o ini_mnc_vars.F: if available (ALLOW_CAL), use startTime_1 and 2 to
2609      create a meaningful unit attribute for the time coordinate variable
2610    o pkg/ebm: add plenty of missing "_d 0" ;
2611       update results of experiment global_ocean_ebm (fwd + adjoint tests)
2612      Notes: several pieces of code only works for (very) specific set up
2613       (domain size, lat range, etc ...); should be documented & stop if one
2614       of those assumptions is not meet.
2615    o pkg/seaice: add missing "_d 0" in HSNOW initialisation
2616       update results of experiments: lab_sea (3 fwd tests + 2 adjoint tests)
2617          and offline_exf_seaice (seaicetd + adjoint).
2618    o add missing "_d 0" in ShortWave flux penetration (S/R SWFRAC):
2619       update results of experiments: lab_sea (4 fwd tests + 3 adjoint),
2620        seaice_obcs, global_ocean.cs32x15 (icedyn & thsice) and natl_box (x2).
2621    o few changes to pass when compiling with strick checking of arguments
2622       across S/R (allow to find few bugs in S/R calls).
2623    o pkg/seaice:
2624     - seaice_evp: move if-statement out of loop (TEM) at the cost of 11 new

2626    
2627    checkpoint61t (2009/07/22)
2628    o pkg/seaice:
2629     - remove unused variables in seaice_evp
2630     - reduce number of SQRT in seaice_evp and seaice_calc_viscosities
2631    o eeset_parms.F, open_copy_data_file.F & ini_parms.F:
2632       named file replacing SCRATCH files (for TARGET_BGL & TARGET_CRAYXT):
2633       each processor opens a different file (a fix from Matt).
2634    o cg2d:
2635       use simple EXCH (overlap size = 1 and ignore corners), like in cg3d.F :
2636       this reduces number of EXCH calls by 2 when using exch2.
2637       For now, keep previous size array for gc2d_nsa.F to avoid Pb with store
2638       directives and missing simple EXCH (exch_s3d_rx) adjoint code.
2639    o pkg/thsice:
2640       add code for Near Infra-Red albedo (from Jeff)
2641       (turned on with run-time flag: thSIce_calc_albNIR, in data.ice).
2642    o ini_model_io:
2643       move (from packages_readparms.F & initialise_fixed.F) to ini_model_io.F
2644       MNC & MONITOR initialisation calls; move MNC calls from {pkg}_readparms.F
2645       to {pkg}_init_fixed.F for {pkg}= kpp, seaice & shelfice.
2646    
2647    checkpoint61s (2009/06/30)
2648    o pkg/exch2 (exch2_rxN_cube*):
2649       remove last BARRIER (no need to synchronise after getting data from shared
2650       buffer (get) as long as any change to buffer (put,recv) is between BARRIER)
2651    o change tiling of natl_box (from 2 to 4 tiles) to get it tested with MPI+MTH
2652      and generate new output (for the 2 tests) using default rotationPeriod.
2653    o pkg/exch2:
2654      - always call exch2_*_cube, not exch-1 anymore, if useCubedSphereExchange=F
2655        (was already the case with AUTODIFF_EXCH2 defined)
2656      - add bj in exch2 arrays and S/R.
2657      - can now use pkg/exch2 for regular (non CS) set-up; switch test experiment
2658        MLAdjust to exch2 (identical results except with MPI -> truncation diff);
2659    o add pkg/longstep for ptracer timestep a multiple of U/V/T/S timestep
2660      - adds deltaT argument to the subroutines TIMESTEP_TRACER DWNSLP_APPLY
2661        GAD_ADVECTION GAD_CALC_RHS GAD_IMPLICIT_R GAD_SOM_ADVECT
