4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/cal:
8     - move calendar setting & summary (previously in cal_readparams.F) into new
9       S/R CAL_INIT_FIXED to be called later in the initialisation process, once
10       length of the simulation is set (after SET_PARMS call); This is an attempt
11       to fix Pb when, e.g.: pkg/longstep, modifies the length of the run.
12     - For safety: keep a record of pkg/cal parameter settings status
13               to allow to STOP if one pkg/cal S/R is called too early.
14    
15    checkpoint63l (2012/04/04)
16    o pkg/bbl:
17      - fix call to FIND_RHO_2D in bbl_calc_rho.F (case multi-tiles per proc);
18        update global_with_exf output.yearly.txt file.
19    o pkg/cal:
20      - start to clean-up cal_set.F ; fix for the case where baseTime is non-zero.
21      - remove 2 unsused and very short (1 line only) functions ;
22      - remove unsused subroutines from AD-Diff list.
23    o model/src:
24      - start to implement clean wait to stop in initialization S/R (config_check.F,
25         packages_check.F, ini_parms.F and pkg/obcs/obcs_check.F + pkg/mypackage)
26    o folowing PRINT_MESSAGE changes:
27      - remove reminder multiple print to the same file (STDOUT) when multi-threads.
28    o pkg/bbl:
29      - modification so it can work with z*
30      - replace deltaT with dTtracerLev(k) for asynchronous time stepping
31      - global_with_exf/input.yearly verification; changes output.yearly.txt
32    o eesupp/src:
33      - PRINT_MESSAGE: use OpenMP critical instruction (similar to PRINT_ERROR);
34        writing to unit 0 (if unit=errorMessageUnit) extended to the case myThid=1
35      - CHECK_THREADS: specific code if using OpenMP threading: improve checking of
36        # of threads across processors (e.g., different env OMP_NUM_THREADS setting)
37      - improve special preliminary call to EESET_PARMS (if eedata is read 2 times).
38      - when using MPI, always set usingMPI=T ; set default accordingly and stop
39        if not consistent.
40      - ALL_PROC_DIE: add a BARRIER after MPI_FINALIZE call ; skip this when thread
41        argument is zero (in case called within single-thread section).
42    o pkg/fizhi:
43        clean-up turbulence cold-start switch: decided in fizhi_init_vars.F, stored
44        in common bloc (fizhi_coms.h) and then passed as argument up to S/R TURBIO.
45    o pkg/exch2:
46      - add argument "updateCorners" to S/R exch2_get_uv_bounds (enable to
47        activate EXCH_IGNORE_CORNERS in vector EXCH S/R).
48      - switch 1rst EXCH call to IGNORE_CORNERS (instead of UPDATE_CORNERS)
49        but keep the 2nd with UPDATE_CORNERS: this prevents overwriting good data
50        with bad ones coming from a not-yet-updated halo.
51        This should fix the problem when sNx <> sNy and GCD(sNx,sNy) < 2*Olx.
52    o pkg/frazil:
53        move FrzForcT diag from frazil_diagnostics_state.F to frazil_calc_rhs.F
54        http://mitgcm.org/pipermail/mitgcm-devel/2012-March/005384.html
55    o model/src/config_check.F: add a check for OLx>sNx/OLy>sNy
56    o verification/lab_sea
57      * #undef SEAICE_EXCLUDE_FOR_EXACT_AD_TESTING
58      * #define ALLOW_SST_CONTROL & ALLOW_SST_CONTROL
59      * nTimeSteps 3 -> 4
60      * changed reference output accordingly
61    o pkg/ctrl:
62      * fix ctrl_get_gen for xx_sst, xx_sss
63    o pkg/fizhi:
64      - fix 2 calls to S/R GRD2MSC (argument igrd) in update_earth_exports.F
65        update results of exp. fizhi-cs-32x32x40 (fail with only 6 digits for cg2d)
66      - by default, use new version of S/R GETPWHERE (#define TRY_NEW_GETPWHERE);
67        fix few out-of-bounds indices in referencing vars (initialise igrd to 1);
68        clean-up fizhi_turb.F (remove unused & uninitialised qdiaglsm array).
69    o pkg/gmredi:
70      - add diagnostic of Redi (main diagnonal) vertical diffusive flux of Temp
71    o pkg/fizhi:
72      - fix few initialisation and multi-tile Pb: aqualev & gridalt now pass the
73        (old)aces open64 tuv test.
74    o pkg/icefront: fix bug and reorder loop in icefront_init_varia.F
75    o pkg/mom_vecinv:
76      - fix 1 loop range in mom_vecinv.F to be like all the other loops which
77        set/update gu,gv/Diss (fix Pb of uninitialised fVerUkp in admom_vecinv
78        with non-lin free-surf).
79    o model/src: move k-loop outside of i/j-loops when (re-)computing R_low
80      in ini/update_masks_etc.F in order to avoid -O3 optimization problems with
81      some compilers (gfortran 4.6.0 on MacOS)
82    o momentum:
83      - separate fVer?(:,:,kUp) & fVer?(:,:,kDown) in argument list of MOM_FLUXFORM
84        & MOM_VECINV subroutines (to help TAF). This fixes Pb of uninitialised
85        fVer?(kUp) in admom_fluxform with non-lin free-surf or bottom control.
86    
87    checkpoint63k (2012/03/17)
88    o model/src:
89       - selectAddFluid (ALLOW_ADDFLUID): add missing term in horizontal momentum
90         flux-form (mom_fluxform.F) and vertical momentum (calc_gw.F) equations.
91       - SOLVE_DIAGONAL: switch default to use adjoinable & vectorized version
92         (#undef SOLVE_DIAGONAL_LOWMEMORY); update output of exp. front_relax.bvp.
93    o model/src: solve_*diagonal.F
94       - replace division with multiplication by inverse (similar to original version)
95         update output of AD exp. global_ocean.90x40x15.
96       - fix pkg/gmredi/gmredi_calc_psi_bvp.F & pkg/ggl90/ggl90_calc.F
97         to enable the use of the vectorized & differentiable solve_tridiagonal.F
98       - test exp. global_ocean.90x40x15/input_ad: switch to advection scheme 20 for
99         vertical advection (to get solve_tridiagonal tested in AD mode).
100    o pkg/seaice: ECCO-CLIVAR merge:
101      1. seaice AREA relaxation
102         * CPP option: SEAICE_ALLOW_AREA_RELAXATION
103         * runtime flag: SEAICE_tauAreaObsRelax
104      2. modified global mean cost imbalance code: CPP option
105          ALLOW_SSH_GLOBMEAN_COST_CONTRIBUTION
106    o another iteration on solve_*diagonal.F
107       Make choices independent of AUTODIFF
108       Default will be the adjoinable vectorized version.
109       Alternative choices are:
110       * non-adjoinable original version with low memory footprint:
111         #define SOLVE_DIAGONAL_LOWMEMORY
112       * still adjoinable but does not vectorize (k as inner-most loop):
113         #define SOLVE_DIAGONAL_KINNER (keeping SOLVE_DIAGONAL_LOWMEMORY undef)
114    o testreport
115     - add option to use a home made wrapper around "make"
116     - remove MITGCM_IEEE env. variable (no longer active)
117    o pkg/shelfice
118     - improve computation of friction velocity for velocity dependent
119       exchange coefficients: include velocities into SHELFICEBoundaryLayer
120       block to average velocities vertically
121     - add TAF store directives for SHI_ALLOW_GAMMAFRICT
122    o Modify diagonal solvers, now three versions (upon request):
123      #ifndef SOLVE_DIAGONAL_AUTODIFF
124        1. default version (dating back a while ago)
125      #else /* def SOLVE_DIAGONAL_AUTODIFF */
126      # ifdef SOLVE_DIAGONAL_KINNER
127        2. adjoinable version with k-innermost loop (G. Forget)
128      # else
129        3. adjoinable vectorized version of 2.
130      # endif
131      #endif /* SOLVE_DIAGONAL_AUTODIFF */
132      All flags are currently set within routines, but could/should be moved to CPP-options.
133      Array bounds for 1. are as before, for 2.,3. cover the entire domain
134      (could be changed for 1. too).
135    o verification/lab_sea (fwd):
136      - update the 4 fwd lab_sea test experiment: no longer SEAICE_GROWTH_LEGACY,
137        use 7 categories (except hb87), new solve4temp params (except salt_plume),
138        constant salinity (=4) or variable salinity (salt_plume) done through
139        SItracer.
140    o pkg/seaice:
141      - rename parameters: SIsalFrac to SEAICE_saltFrac & SIsal0 to SEAICE_salt0;
142      - remove old parameters ( SEAICE_freeze, SEAICEturbFluxFormula, SEAICE_gamma_t,
143         SEAICE_gamma_t_frz, SEAICE_availHeatTaper & SEAICE_availHeatFracFrz)
144        from SEAICE_PARMS.h ; still need to fix seaice_cost_sst.F (broken when
145        SEAICE_freeze got retired) but already better than previously with
146        SEAICE_freeze=123456.7 deg.C;
147      - move setting of facOpenGrow/Melt from SEAICE_INIT_FIXED to SEAICE_READPARMS
148        (safer multi-threaded setting); always set SEAICEuseEVP;
149      - setting of ocean-ice turb. flux coeff: moved from SEAICE_CHECK to
150        SEAICE_READPARMS & SEAICE_INIT_FIXED (this fixes wrong summary report);
151        stop if multiple specifications for the same coeff; make sure default
152        SEAICE_mcPheePiston is compatible with drF(1) & deltaT.
153    o pkg/obcs:
154      - allow to switch to upwind 1rst order advection scheme for the advective
155        flux computation at the open-boundary; disabled for adjoint built.
156    o pkg/ptracers:
157      - rename PTRACERS_RESTART.h -> PTRACERS_START.h
158      - rename ptracers_fields_blocking_exchanges.F -> ptracers_fields_blocking_exch.F
159      - add parameter to decide when to start a tracer; use internal flag to
160        know which tracer to step-forward; switch this internal flag at the top
161        of forward_step.F (new S/R PTRACERS_SWITCH_ONOFF); for now, not enabled
162        for adjoint built.
163    o pkg/seaice:
164      - add SEAICE_SIZE.h anywhere in the code where SEAICE.h is included ;
165      - move MULTDIM declaration and setting from SEAICE.h to SEAICE_SIZE.h ;
166      - keep experiment offline_exf_seaice truly single category (set MULTDIM=1).
167    o pkg/ecco:
168      - fix writing of output file DiagnosCost_ClimSalt/Theta
169        and DiagnosCost_DriftSalt/Theta (if multi-tiles per proc).
170    o pkg/seaice:
171      - add missing initialisation of COR_ICE array in dynsolver.F
172      - merging SEAICE_MULTICATEGORY define and undef cases. Now the same code is
173        compiled either way, and is tested in all exps (multidim was only tested
174        in lab_sea ad before).
175      - cosmetic change to prepare for future addition of ITD. no change to results.
176        no defaults change.
177      - added run time param SEAICE_multDim (7 for SEAICE_MULTICATEGORY, 1 otherwise).
178      - by lack of adequate verification experiments, I further used custom versions
179        of global_ocean.cs32x15 to test multicat or not, with pickup or not. All
180        should be correct.
181      - avoid recomputations in ad.
182    o array initialisation in adjoint mode:
183      1) pkg/mom_common/mom_calc_ke.F:
184        add full array initialisation of KE inside mom_calc_ke.F (ALLOW_AUTODIFF_TAMC):
185        The S/R which calls MOM_CALC_KE initialises KE but in some recomputation
186        part this initialisation is gone, resulting in Floating Point Exception
187        (caught by open64 compiler with debug option).
188      2) model/src/convective_weights.F
189        set output convectCount over the full array range (instead of doing
190        an update): this fix a similar issue when called within recomputation (adjoint)
191        which could by-pass the initialisation (normally done in the caller S/R).
192    o pkg/seaice:
193      - final version of turbulent flux params, as agreed at MIT ice meet:
194           SEAICE_mcPheePiston (default is ~ 0.000875)
195           SEAICE_mcPheeTaper (default is 0.)
196           SEAICE_frazilFrac (defualt is 1.)
197           SEAICE_mcPheeStepFunc (default is false)
198      - changes results at trunction error level
199      - ifdef SEAICE_EXTERNAL_FLUXES, disallow SEAICE_waterAlbedo
200    o added pkg/frazil:
201      - see frazil_description.tex for details
202      - verification experiment is global_with_exf/input.yearly; changes output.yearly.txt
203    o pkg/shelfice/shelfice_thermodynamics.F
204      - fix exponents for velocity dependent exchange coefficients: change
205        from 2/3(=0) to 0.66666666666666667
206      - move computation of velocity dependent exchange coefficients into
207        separate loop, so that it applies to both thermodynamics
208      - move some divisions by constants out of loops
209    
210    checkpoint63j (2012/02/16)
211    o pkg/seaice:
212      - overhaul of seaice_summary.F after feb 2012 clean-up of seaice_growth.F etc.
213      - SItracer:  added run time params, and allow coupling to ocn salinity.
214    o pkg/seaice: remove (almost) all divisions by constants within loops
215      in seaice_growth.F and seaice_solve4temp.F, this changes (only) the cg2d
216      results of global_ocean.cs32x15.seaice from 16 to 11 digits (but only
217      those, caused by 1/QI -> recip_QI) -> update output.seaice.txt,
218      output_adm.seaice_dynmix.txt and also lab_sea: output_adm.evp.txt
219    o pkg/seaice :
220      - simplify McPhee tapering, and allow to use it with SEAICEturbFluxFormula
221        = 1 or 2, using newly added run time parameter SEAICE_availHeatTaper.
222      - fix d_AREAbyATM, d_AREAbyOCN, d_AREAbyICE diags I broke in r1.148.
223      - add permanent SItflux diag that corresponds to TFLUX but includes
224        ice+snow. Hence SItflux-TFLUX should match the ice+snow heat budget.
225      - allow activation/testing of a fix for suspected missing term in
226        ocn-ice heat budget (to be confirmed). To test this, you want to
227        undef SEAICE_DISABLE_HEATCONSFIX, and then set the run time param
228        SEAICEheatConsFix to .TRUE. that also allows the 'SIaaflux' diagnostic.
229      - no change in results, fwd or ad.
230    o global_ocean.cs32x15/results: 3 changes following from the pkg/seaice commit below:
231      - switch to variable freezing point.
232           Results change : cg2d -> 1 digits; ad -> 3-6-6 digits.
233      - bug fix : the sublimation term that was missing is now activated.
234           Results change : cg2d -> 2 digits; ad -> 8-6-6 digits.
235      - bug fix : flooding sign term for SIsal0.NE.0.
236           Result change : cg2d -> 8 digits; ad -> 11-12-9 digits.
237    o pkg/seaice:
238      - unified freezing point treatment : the old SEAICE_VARIABLE_FREEZING_POINT
239        is now the default, and the old default constant freezing point is recovered
240        with SEAICE_tempFrz0    = -1.96,
241             SEAICE_dTempFrz_dS = 0.,
242      - retire SEAICE_freeze (= the old way of specifycing the constant freezing point)
243      - remove ALLOW_SEAICE_FLOODING brackets; run time switch is already there.
244      - bug fix (thanks to M. Losch) : the sublimation term that was missing is now
245        activated. To reproduce old results with this bug define SEAICE_DISABLE_SUBLIM.
246      - bug fix (silly me) : flooding sign term (seaice_growth.F r 1.149line 1211)
247        was wrong for SIsal0.NE.0. Changes cs32x15 results (see above item for detail).
248      - bug fix (thanks to O. Jahn) : area loss for melting  got messed up in
249        seaice_growth r149 for legacy branch (no results change).
250      - introduce SEAICE_CAP_SUBLIM : caps sublimation heat flux in solve4temp (code
251        from I. Fenty).
252      - results did not change except for global_ocean.cs32x15, mostly due to the
253        switch to variable freezing point (see above item for detail).
254    o pkg/thsice:
255      - fix and simplify interface to salt_plume pkg ; diagnose directly amount of
256        seawater freezing in thsice_calc_thickn (not used).
257    o pkg/seaice: turbulent flux term specification via run time params.
258      - replace CPP switches with run time switches to facilitate testing
259      - retired CPPs : MCPHEE_OCEAN_ICE_HEAT_FLUX,
260                       GRADIENT_MIXED_LAYER_TURBULENCE_FACTOR
261      - added runtime parameter : SEAICEturbFluxFormula
262      - move Mcphee constants to SEAICE_PARAMS.h
263      - seaice_readparms.F : read turbulent flux term params (SEAICEturbFluxFormula;
264                 SEAICE_availHeatFrac/Frz, or SEAICE_gamma_t/_frz if apply);
265                 remove seaice_summary call (moved to seaice_init_fixed)
266      - seaice_init_fixed.F : set SEAICE_availHeatFrac/Frz depending on
267        SEAICEturbFluxFormula, and seaice_summary call (moved from seaice_readparms)
268      - seaice_summary.F : add missing report of read turbulent flux term set up
269                           and SITRACER.
270      - seaice_check.F : check range; inform and stop if retired CPPs are used
271                         (incl. SEAICE_AGE).
272      - seaice_growth.F : unified use of SEAICE_availHeatFrac/Frz, without
273             CPP switch, same computation as before for the different options.
274      - change results at the truncation level.
275    o pkg/seaice:
276      - remove un-used parameters LAD & MAX_TICE ; add new run-time parameters:
277        useMaykutSatVapPoly (default=F), postSolvTempIter (default=2) and
278        SEAICE_wetAlbTemp (default=-1e-3). Remove option SEAICE_SOLVE4TEMP_LEGACY.
279      - update verification/*/input*/data.seaice:
280        to reproduce previous results with former #defined SEAICE_SOLVE4TEMP_LEGACY
281        code, set useMaykutSatVapPoly=T & postSolvTempIter=0 ;
282        and to reproduce previous results with former non-SOLVE4TEMP_LEGACY code,
283        set SEAICE_wetAlbTemp=0 & SEAICE_snowThick=0.
284    o pkg/seaice/seaice_solve4temp.F (SOLVE4TEMP_LEGACY):
285      - remove LEGACY code for solving for tsurf (A1,A2,A3) but maintain the same
286        algorithm (same choice: useMaykutPolySatVap=T, postSolvTempIter=0);
287        difference in results only due to machine truncation.
288      - remove MAX_TICE (tsurf is always =< TMELT anyway); keep MIN_TICE if using
289        MaykutPolySatVap; keep MIN_LWDOWN.
290      - adapt SEAICE_MODIFY_GROWTH_ADJ code (untested) to non-legacy formulation.
291      - update output of verification exp. lab_sea (4 fwd: 11 cg2d digits except hb87,
292        + 3 AD: 6 digits except evp) and offline_exf_seaice.seaice (12 digits).
293    o pkg/salt_plume:
294      - isolate saltPlumeFlux array exch into a specific S/R called from
295        do_oceanic_phys.F
296      - add interface to pkg/salt_plume (filling of saltPlumeFlux) in pkg/thsice.
297    o verification:
298      - move untested set-up to MITgcm_contrib/verification_other.
299    o pkg/seaice:
300      - retire old way of SEAICE_AGE. Now replaced with ALLOW_SITRACER.
301    o pkg/seaice:
302      - seaice_solve4temp.F (keeping results unchanged):
303        * add 2 future run-time params to select which saturation vapor pressure
304          formula is used and how post-iteration fluxes are set.
305          Temporary set these 2 params according to option SOLVE4TEMP_LEGACY;
306        * New piece of code (not used) to update surf. atmos. heat flux F_ia using
307          the linearized expression to stay consistent with tsurf finding.
308      - seaice_freedrift.F avoid floating exception in sqrt(y) since y=sqrt(x*x)-x
309        can be < 0.
310    o pkg/seaice/seaice_solve4temp.F (SOLVE4TEMP_LEGACY undef):
311      - remove from F_ia (and from it's derivative dFiDTs1) the contribution of
312        conductive heat flux F_c , and add it explicitly when updating tsurf as
313        solution of: Fc = Fia + d/dT(Fia - Fc) *delta.tsurf
314        so that now F_ia has a consistent meaning through the entire routine.
315        This causes differences at truncation level: update output of fwd exp.
316        global_ocean.cs32x15.seaice.
317    o pkg/seaice:
318      - lots of editing/cleaning in seaice_solve4temp.F + better documentation
319        of arrays, sign/direction of fluxes; no effect on results.
320      - replace hard coded 273.16 (=previous value of celsius2K) by celsius2K
321        in seaice_budget_ocean.F & seaice_solve4temp.F (SOLVE4TEMP_LEGACY part);
322        note: this should have been done before changing celsius2K default.
323      - to keep results unchanged, add back old value of celsius2K in verification
324        exp. input*/data : lab_sea (AD), offline_exf_seaice (fwd+AD) & seaice_obcs
325      - replace hard coded seawater freezing temp in seaice_solve4temp.F (part
326        SOLVE4TEMP_LEGACY) of 271.20 (=previous value of celsius2K + default
327        value of SEAICE_freeze) by celsius2K+SEAICE_freeze so that seawater
328        freezing temp is consistent with value in seaice_growth.F ; this causes
329        differences at machine truncation level: update lab_sea AD output (3/4).
330    o pkg/seaice:
331      - mask (in exf_init_fixed.F) atemp,aqh,evap,precip,runoff,lwflx,areamask
332        and climsst/sss even when using seaice (to prevent calculation that might
333        use SST on land); does not affect any verification exp.
334      - apply mask to taux,tauy (in seaice_get_dynforcing.F); update output
335        of lab_sea.fd & lab_sea.hb87 and global_ocean.cs32x15.seaice_dynmix.
336    o pkg/seaice/seaice_growth.F: add mask to avoid non-zero ice thickness
337      over land (non-legacy code)
338    o vectorize salt_plume package:
339      - add extra code to salt_plume_frac and salt_plume_tendency_apply_s
340      - this code computes plumebk everywhere (also over land), thus requires
341        code to avoid divisions by zero and catch the case of kLev=Nr.
342      - efficiency of salt_plume_frac is still sub-optimal
343    o tools (genmake2):
344      - fix makefile NAME specification (option: -makefile NAME) by adding
345        "-f $MAKEFILE" in few places where it was missing including makedepend
346        command (contribution from Paul).
347    
348    checkpoint63i (2012/01/24)
349    o model/src:
350      - add factorized versions of some EOS code to find_rho.F,
351        define USE_FACTORIZED_EOS to turn it on (default for TARGET_NEC_SX)
352    o model/src:
353      - add celsius2K to namelist PARM01; remove unused recip_rhoNil from PARAMS.h;
354      - change default celsius2K from 273.16 to 273.15
355      - to keep results unchanged, add back old value of celsius2K in verification
356        exp. input*/data : aim.5l_cs, 1D_ocean_ice_column, lab_sea (fwd),
357         global_ocean.cs32x15(seaice) & cpl_aim+ocn(input_atm).
358    o model/src: add a little initialisation trick to find_rho.F and find_alpha.F
359      to make TAF generate vectorizable code
360    o pkg/seaice/seaice_evp.F: add code (copied from CICE) that avoids underflows.
361       Turn on by defining SEAICE_EVP_ELIMINATE_UNDERFLOWS. Most compilers
362       have flags that do this more efficiently.
363    o pkg/diagnostics/diagstats_calc.F
364      - for TARGET_NEC_SX fix the treatment of the scaling factor tmpFac=scaleFact
365    o pkg/obcs (with exch2):
366      - derive OB indices in overlap region from OB-InsideMask (in obcs_init_fixed.F)
367        and remove code (in obcs_readparms.F) which was based on EXCH of indices
368        (through buffer) and did not account for exch2 (e.g., CS-grid) topology.
369    o pkg/exf and seaice exp:
370      - change offline_exf_seaice.seaicetd test exp. to use default DIFF1 value (=0)
371        so that switching off area & heff advection flags does not affect results.
372      - change default EXF_LWDOWN_WITH_EMISSIVITY to #define in EXF_OPTIONS.h
373      - keep exp. seaice_obcs & 1D_ocean_ice_column(ad) unchanged (using #undef
374        EXF_LWDOWN_WITH_EMISSIVITY) and, using pkg/exf default emissivities, update
375        results of verification experiments: 1D_ocean_ice_column(fwd),
376        global_ocean.cs32x15.seaice(fwd+ad) & seaice_dynmix(ad), lab_sea (all 8)
377        and offline_exf_seaice (all 4).
378    o pkg/seaice:
379      - remove array YNEG, RIVER, TMIX (replaced by local var) from common block;
380        remove also areaNm1 & hEffNm1 when SEAICE_GROWTH_LEGACY is undef.
381      - fix bug: areaNm1 & hEffNm1 are needed in seaice_growth (SEAICE_GROWTH_LEGACY)
382        but were not filled when resp. SEAICEadvArea=F & SEAICEadvHeff=F and
383        not multi-dim advection;
384      - fix seaice_growth.F to compile with both SEAICE_GROWTH_LEGACY and
385        SHORTWAVE_HEATING #undef.
386    o optim: make Makefile more robust (?)
387    o pkg/obcs:
388      * fix treatment of obcs_read_pickup for TAF
389    o pkg/shelfice:
390      * add missing initialisation of num_shifwflx
391      * new adjoint verification exp. for isomip
392      * change Prandtl and Schmidt numbers from generic formulations
393        (in terms of model diffus. and visc.) to separate runtime
394        parameters, with Holland and Jenkins (1999) default values.
395    o pkg/exf (interpolation):
396      - extended input field (2 rows) near the N & S poles:
397        * fill in with the symetric value (when even Nb of data in longitude)
398        * add average value at the poles only for scalar quantities ; for vector
399          component interpolation, skip the averaging and keep duplicated values,
400          unless the 2 components have same location (uvInterp=T) in which case
401          interpolate the 2 components together using S/R EXF_INTERP_UV.
402      - new S/R EXF_INTERP_UV to interpolate the 2 components of a vector field
403        together: this allows to account properly for local orientation when
404        averaging at N & S pole.
405      - add CPP option EXF_USE_OLD_INTERP_POLE to recover old results regarding
406        exf-interpolation near N & S poles. Undef by default.
407      - add debug check/print on 1rst iter if debugLevel >=2.
408    o pkg/exf:
409      - change masking flags definition (no longer "parameter"), put them in
410        common block and set them in S/R EXF_INIT_FIXED.
411      - change recognized masking flag from s,u,v to c,w,s since the mask
412        to use (maskC,W,S) depends on position on model grid and has little to
413        do with scalar/vector difference; fix masking if using P-coordinates.
414      - fix masking of wind-stress (was wrong if interpolated or read on A-grid)
415        and update results of exp. global_with_exf (x2).
416      - fix setting of zenith-angle table when SHORTWAVE_HEATING is undef.
417    o pkg/obcs
418      - S/R obcs_calc_stevens: fix a small bug (gammat -> gammas where appropriate)
419    o pkg/exf (interpolation):
420      - assume periodicity in X only if input field cover full longitude range.
421      - improve search for lat. index (supposed to be faster, in ~log2(ny) steps,
422        and should vectorise).
423      - fix input lat of the 2 added row (in case we provide N.pole data).
424    
425    checkpoint63h (2011/12/30)
426    o pkg/seaice:
427      - change declaration of UVM from _RL to _RS in order to get B-grid
428        uIce,vIce monitor when _RS = real*4
429    o pkg/offline:
430      - new S/R OFFLINE_RESET_PARMS for resetting main-model params (switch off flags);
431      - compute vertical velocity if not read from file (switch on exactConserv
432        & staggerTimeStep);
433      - fix output of ptracer monitor iter & time for default PTRACERS_monitorFreq.
434    o verification:
435      - update grid-files (in tutorial_held_suarez_cs/input and fizhi-cs-32x32x40/input)
436        with grid-angle generated using "utils/matlab/cs_grid/cubeCalcAngle.m":
437        fix Pb in yG definition @ 2 missing corners (previously yG was averaged);
438      - update output of exp. global_ocean.cs32x15.viscA4 after changing
439        grid-file angles (used here for coriolis-3d);
440      - remove (or gzip) few files not needed to run fizhi-cs experiments.
441    o pkg/exf (vector interpolation):
442      - rotate vector component toward local grid-axis orientation using grid-angles
443        (stored in GRID.h) instead of locally computed rotation angle; keep old code
444        available with exf option EXF_USE_OLD_VEC_ROTATION (undef by default).
445    o pkg/seaice:
446      - allow to compile with exf options ALLOW_ATM_TEMP or ALLOW_DOWNWARD_RADIATION
447        undefined. Fix and remove the stop when ALLOW_RUNOFF is undefined.
448    o pkg/PKG_OPTIONS.h files:
449      - move #include "CPP_OPTIONS.h" just after #include "PACKAGES_CONFIG.h",
450        outside of the #ifdef ALLOW_THISPKG / #endif block.
451      - update verification/*/code/PKG_OPTIONS.h files.
452    o add a verification experiment (offline_exf_seaice/input.seaice) that test
453      the B-grid LSOR solver
454    o pkg/seaice: sort out emissivity and long wave radiation step 2:
455      - add emissivity for snow and ice as new run-time parameters
456        (unfortunately) that default to the corresponding exf values; this
457        changes results in most verification experiments so that for backward
458        compatibility these parameter have to be set explicitly to inconsistent
459        values (ugly);
460      - the exf-flag EXF_LWDOWN_WITH_EMISSIVITY then gets rid off the hard-wired
461        emissivities of 0.97 associated with lwdownloc in S/R seaice_solve4temp
462        until we agree how to handle this bug properly
463    o pkg/exf (interpolation):
464      - add a set of run-time param ({inputfield}_interpMethod), one for
465        each interpolated input field, to select the interpolation method
466        with a value of zero switching off the interpolation;
467      - print interpolation parameters to standard output;
468      - refine exf_check.F accordingly ; stop if USE_NO_INTERP_RUNOFF is defined
469        (to use instead runoff_interpMethod=0 in data.exf).
470      - simplify default setting of interpolation parameters (for all fields,
471        set position to match model grid cell-center position, leading to trivial
472        interpolation in case of regular Lat-Lon grid) and fix for the case of
473        non-uniform delY.
474    o pkg/exf/exf_radiation.F: add the factor ocean_emissivity to lwdown, for
475       within #ifdef EXF_LWDOWN_WITH_EMISSIVITY/#endif. Unless ocean_emissivity=1.
476       this factor is absolutely required, because the lw exitance (= out-going
477       long wave radiation) is emissivity*stefanBoltzmann*T^4 + rho*lwdown,
478       where the reflectivity rho = 1-emissivity for conservation reasons. Once
479       this is established, we can remove the CPP-Flag (if we want to).
480    o pkg/seaice:
481      - qualify a stop statement in S/R seaice_check: EXF_READ_EVAP and
482        ALLOW_BULKFORMULAE are only required if SEAICE_EXTERNAL_FLUXES is defined
483      - sort out emissivity and long wave radiation, step 1: make SEAICE_emissivity
484        what the name implies (and not emissivity*BoltzmannConstant), this means
485        the old default value of 5.5e-8 now means
486        5.5e-8/5.670e-8 = 0.97001763668430343479 as ocean_emissivity in
487        S/R exf_readparms
488      - FV-discretization of the B-grid LSOR solver, turn on with
489        SEAICE_LSRBNEW. This new solver also involves a slight re-organization
490        of the calling routine dynsolver, so that B and C-grid code look a
491        little more alike.
492      - fix index bugs in ostres.F (B-grid code)
493    o pkg/seaice/seaice_ocean_budget.F: change (unused) code to make it look better
494    o pkg/seaice/seaice_readparms.F: make ocean_emissivity*stefanBoltzmann the
495      default for SEAICE_emissivity, if useEXF; requires setting a wrong
496      parameter value in global_ocean.cs32x15/input.seaice/data.seaice for
497      backward compatiblity
498    o model/src: use sigmaR in calc_ivdc
499    
500    checkpoint63g (2011/12/16)
501    o pkg/seaice/seaice_growth.F:
502      fix heat conservation of the coupled ocean-seaice system.
503      when SEAICE_HEAT_CONSERV_FIX is defined, the mismatch of
504      solid vs liquid water treatment is resolved via QNET.
505    o pkg/seaice/seaice_growth.F:
506      add missing term for sublimation in saltFlux, which was breaking conservation.
507    o pkg/seaice/seaice_model.F:
508      Remove this patholigical case treatment in evolution branch,
509      where it is un-necessary and breaks conservation.
510      Update global_ocean.cs32x15/results accordingly for
511      output.seaice.txt output_adm.seaice.txt and output_adm.seaice_dynmix.txt
512    o model/src:
513      useRealFreshWaterFlux: remove masking of EmPmP (using maskInC) in
514      external_forcing_surf.F and apply mask directly in S/R SOLVE_FOR_PRESSURE.
515    o pkg/obcs:
516      modify Stevens boundary conditions so that S/R obcs_calc_stevens computes
517      tendency for temperature and salinity that is then applied to update
518      theta and salt in S/R obcs_apply_ts; this requires proper masking of all
519      horizontal advection and diffusion contributions on the boundary (in
520      S/Rs gad_advection, gad_calc_rhs, gmredi_rtransport, gmredi_calc_diff), and
521      removing the mask in S/R timestep_tracer. The advantage of this approach is
522      that the updated tracer values include contributions from the surface
523      forcing and vertical diffusion.
524      This modification changes exp4.stevens because of vertical diffusion.
525    o model/src:
526      change non-curvilinear grid setting to also work with exch2 + blank tiles:
527      - move delX,delY to new header file (SET_GRID.h) and adjust length to 1rst
528        face dimensions.
529      - new S/R INI_LOCAL_GRID to define model tile-local grid (using same units
530        as delX,delY) and called from S/R INI_CARTESIAN_GRID, INI_CYLINDER_GRID
531        and INI_SPHERICAL_POLAR_GRID.
532      change test-experiment global_ocean.90x40x15:
533      - split the domain in many more tiles (9x4 tiles of 10x10 each);
534      - switch to exch2 and remove 1 blank-tile (but only for MPI test).
535      - update results of both test (std & dwnslp).
536    o pkg/diagnostics/diagstat_calc.F: fix problem with non-initialised halos in
537       tmp-fields for TARGET_NEC_SX at the cost of extra loops and less vectorisation
538    o model/src:
539      - take sigma-coords related code out of update_etah.F into new S/R UPDATE_ETAWS
540        and fix initialisation when using sigma-coords.
541    o model/src:
542     - improve Gael's changes from Jan 14, 2011 "addition of an 'update' of hfacc etc.
543       to their current value at the beginning of forward_step.F": add a new run-time
544       switch "doResetHFactors" (default=false) and use it to do (or not) the resetting.
545     - set doResetHFactors=T in the following test exp:
546        global_ocean.90x40x15/input (rStar) & input.dwnslp (linFS),
547        global_ocean.cs32x15/input.seaice (rStar), hs94.cs-32x32x5/input.impIGW (linFS)
548        and tutorial_global_oce_in_p (nonLinFS in p)
549    o pkg/ecco
550      - added IES cost term
551    o verification/advect_xz
552      - scale down the depth by 1/100 (from 200 km to just 2.km)
553      - add secondary test using divergent flow, r-star and implicit vertical advection.
554      - add note (check_conserve_TS.txt) and matlab script to check global
555        conservation of T & S with NonLin-FreeSurf and Adams-Bashforth.
556    o pkg/rbcs:
557      - add missing relaxUFile & relaxVFile in namelist (in rbcs_readparms.F).
558    o pkg/obcs (Stevens BCs):
559      - fix various problems in the phase speed computations of the Stevens
560        boundary conditions:
561        - sign error for western and southern boundaries,
562        - time tendencies were underestimated by factor of dTracerLev and some just
563          zero (for multidim advection schemes) -> now estimate time tendencies
564          from difference between previous (n) time level and the one before (n-1);
565          this requires storing a field per tracer per boundary, also in the pickup
566          files.
567        - replace deltaTmom in cflMer/Zon computation with dTracerLev
568        - set default phase velocity to cflMer/Zon
569      - update verification experiment exp4.stevens
570    o pkg/generic_advdiff (implicit_r):
571      - fix implicit vertical advection conservation with AB and/or NonLin-FreeSurf
572        (remove Tr*d/dz(w) in gad_implicit_r.F and add it in gad_calc_rhs.F);
573      - fix implicit vertical diffusion or advection with NonLin FreeSurf
574        (was using current recip_hFacC instead of future recip_hFacC): set future
575        recip_hFac in thermodynamics.F and pass & use it in all vertical implicit
576        solver S/R ;
577      - fill diagnostics of vertical advective fluxes (computed from tendency)
578        when using implicit vert. advection;
579      - update output of exp that uses NonLin-FreeSurf & implicit vertical diffusion:
580         global_ocean.90x40x15 (fwd+AD), global_ocean.cs32x15 (4 fwd +4 AD),
581         tutorial_global_oce_in_p (fwd), tutorial_tracer_adjsens (AD)
582         and cpl_aim+ocn (used in ocean); to be fixed: bottom_ctrl_5x5.
583    o pkg/diagnostics:
584      - add diags for T & S tendency which goes through Adams-Bashforth.
585    
586    checkpoint63f (2011/11/30)
587    o pkg/obcs/obcs_calc_stevens.F:
588      - join some loops to reduce number of if-statements
589      - fix a bug in code for northern and southern boundaries.
590    o pkg/seaice/seaice_init_varia.F
591      - undo resetting UVM=0 that has slipped in unnoticed in r1.49 and
592        caused zero ice-velocities for the B-grid code
593    o pkg/seaice/seaice_init_fixed.F
594      - fix a bug in the initialisation of the second metric terms
595        k2AtC and k2AtZ: k2AtC was set to the value of k2AtZ and k2AtZ was 0.
596      - this affects all seaice configurations with useCurviLinearGrid = .true.
597        and SEAICEuseDynamics = .true. (default) and SEAICEuseMetricTerms
598        = .true. (default)
599      - the only verification experiment affected is global_ocean.cs32x15:
600        icedyn, seaice, and seaice_dynmix (AD)
601    o pkg/thsice/thsice_diagnostics_state.F
602      - only for TARGET_NEC_SX: initialise all of tmpFld, so that overlap does
603        not contain garbage that can lead to surprises in diagstats_calc.F
604    o model/src:
605      - move bi,bj loops inside INTEGR_CONTINUITY ;
606      - call INTEGR_CONTINUITY directly from forward_step.F
607        (previously called from momentum_correction_step.F)
608      - call UPDATE_ETAH from integr_continuity.F and update initialise_varia.F,
609        forward_step.F and pkg/ecco/the_main_loop.F
610    o model/src/do_oceanic_phys.F:
611      - reset addMass to zero only if useICEFRONT ;
612      - separated k-loop for rhoInSitu calculation ;
613      - add 2 diagnostics for wVel*delta^k(Rho) at constant pressure (= WdRHO_P)
614        and at constant T,S (= WdRHOdP);
615      NOTE: change diagnostics WRHOMASS : this is now simply the Vertical transport
616        of In-Situ Density (Anomaly) (=wVel*rho^bar-k) (previously was Vertical
617        transport of locally-referenced potential density);
618        to recover old diag: (WRHOMASS)_old = (WRHOMASS)_new -1/2 * (WdRHOdP)
619    o gluemnc:
620      - replace ncrcat with ncks when adding variables to *.glob.nc
621      - change the way variables without record dimensions are handled so that
622        files that have variables with and without record variables can be glued:
623        add a record dimension with a new unique name to be able to differentiate
624        between variable with and without a-prior record dimensions. Remove
625        this record dimension before adding the variable to the *.glob.nc file.
626        This procedure automatically works also for grid.*.nc files that do not
627        have any record dimension.
628    o verification/cpl_aim+ocn:
629      - generate new reference output on baudelaire (gfortran, mpich2) (previously
630        from old aces-grid cluster, ao + ifort) and update 'run_cpl_test' script.
631    o pkg/obcs/obcs_calc_stevens.F:
632      - add code for northern and southern boundaries.
633      - reorder some loops to save some operations and so that drFBar can be scalar
634    o model/src:
635      - re-arrange extrapolation calculation in Adams-Bashforth S/R (affects machine
636        truncation) and add diagnostics for Adams-Bashforth tendency increment.
637      - update test-exp. AD output:
638        1D_ocean_ice_column, bottom_ctrl_5x5, lab_sea.noseaicedyn, obcs_ctrl;
639      and FWD output: exp4 (x3), fizhi-cs-32x32x40, fizhi-cs-aqualev20,
640        front_relax (x3), global_ocean.90x40x15 (x2), global_ocean.cs32x15 (x5),
641        global_ocean_ebm, ideal_2D_oce, internal_wave, isomip (x3), lab_sea (x4),
642        matrix_example, MLAdjust (x5), natl_box (x2), tutorial_advection_in_gyre,
643        tutorial_global_oce_in_p, tutorial_global_oce_latlon and
644        tutorial_plume_on_slope.
645    o pkg/diagnostics/diagstats_calc.F: add special code for TARGET_NEC_SX
646      that vectorises. This code uses 3 extra 2D fields, F90 array assignments
647      and F90 intrinsic routines SUM, MINVAL, MAXVAL, but since TARGET_NEC_SX
648      does not even come with an F77 compiler anymore, this should not be
649      a limitation
650    
651    checkpoint63e (2011/11/06)
652    o pkg/seaice adjoint of LSR:
653      - substantially rework STORE dirs.
654      - add new flag SEAICE_LSR_ADJOINT_ITER and parameter SOLV_MAX_FIXED
655        this flag will do SOLV_MAX_ITERS but only store SOLV_MAX_FIXED fields
656        and only perform SOLV_MAX_FIXED adjoint iters.
657        If flag SEAICE_LSR_ADJOINT_ITER is undef-ined, the store in the iteration
658        always goes to same record, meaning that the last forward field will be
659        the one used in the adjoint - an approximation.
660      - now produces non-zero LSR-related gradients, and acceptable gradients for
661        An's zonal (x-z) test case (to be checked in)
662      - lab_sea: produces acceptable gradients for lab_sea with forward/backward LSR
663        (but these are screwed up by the thermodynamics in the first place);
664        reduce from 4 to 3 timesteps to avoid t.d. issue as temporary solution;
665        output_adm.txt also reflects changes to seaice_lsr
666      - global_ocean.cs32x15:
667        * the "default" input_ad.seaice has been re-defined to always exclude dynamics
668          (output_adm.seaice.txt was updated)
669        * new input_ad.seaice_dynmix tests a forward LSR / backward free-drift
670          (output_adm.seaice_dynmix.txt)
671    o test-exp. exp4+stevens:
672      - switch off pTracers and nonHydrostatic (restart problems with NH); update output
673    o pkg/seaice (lsr solver):
674      - put coriolis term into FORCEX,Y (as in seaice_evp.F; previously in rhsU,V only);
675        update output (change truncation) of FWD test exp lab_sea & global_ocean.cs32x15
676      - fix SEAICEuseFREEDRIFT for new OBCS version (ndef OBCS_UVICE_OLD)
677      - new parameter "LSR_mixIniGuess" allows (if=2,4) to mix free-drift solution
678        into initial guess for linearised solver; use weight ~ (1/err)^2,4.
679      - compute (with new S/R) and print initial (+ free-driff sol. if available)
680        and final residual of linearised system.
681    o pkg/pp81: add diagnostics for vertical eddy viscosity and diffusivity
682      (requires new subroutines pp81_init_fixed.F/pp81_diagnostics_init.F)
683    o pkg/obcs: Stevens BCs (still only for east and west)
684      - fix Stevens BCs by using intermediate velocities of previous
685        time step as "baroclinic" contribution rather velocity of one grid cell
686        inside the boundaries; more consistent but makes the entire treatment
687        more complicated, requires new pickup files and two new S/Rs:
688        obcs_copy_uv_n and obcs_save_uv_n
689        keep old version with flag OBCS_STEVENS_USE_INTERIOR_VELOCITY
690        (undefined by default)
691      - silently move computation of some grid factors into separate loops to
692        save some recomputations
693      - add a hack for non-linear free surface
694      - add a verification experiment to exp4 that tests this code
695    o make gluemnc/xplodemnc work with (moron) non-GNU shell tools
696    
697    checkpoint63d (2011/10/25)
698    o pkg/obcs + seaice-dynamics:
699      - new implementation calls OBCS_APPLY_UVICE (in seaice_dynsolver.F) before
700        solving for uIce,vIce and prevent SEAICE_LSR or SEAICE_EVP to modify OB
701        values (consistent with an implicit method).
702      - add option OBCS_UVICE_OLD (in OBCS_OPTIONS.h, defined by default) to
703        return to older implementation (same results as before); note that none of
704        the "experimental" OBCS_SEAICE options are implemented in the new version.
705      - switch test exp. seaice_obcs to use new version (update output).
706    o pkg/seaice:
707      - add few stop (B-grid & CS-exch, B-grid & obcs, AUTODIFF & SEAICE_maskRHS)
708      - add parenthesis in Water-Ice drag calculations (evp & lsr);
709      - in seaice_lsr.F, simplify and fix AA3 setting in case sNx or sNy=1;
710        and fix case SEAICE_waterDrag=0 (but unstable if no or little seaice)
711      - update output of test exp lab_sea that uses evp or lsr (fwd+ad)
712        and global_ocean.cs32x15 (icedyn & seaice fwd+ad).
713    o pkg/layers:
714      - Include potential density as new coordinate (Thanks to David Munday)
715    o pkg/dic:
716      - Remove subroutine CALC_PCO2_APPROX_CO3 from carbon_chem.F and add
717        carbonate computation/output to CALC_PCO2_APPROX
718    o pkg/generic_advdiff
719      - make TAF generate code that vectorizes:
720        gad_dst3fl_adv_*.F, gad_u3c4_impl_r.F
721    o model/src:
722      - improve vectorization also for adjoint code of
723        solve_tridiagonal and solve_pentadiagonal. As this requires up to
724        5 new 3D-fields, this code is only turned on for the combination of
725        ALLOW_AUTODIFF_TAMC and TARGET_NEC_SX. Also remove error message
726        for singular matrix check (only for TARGET_NEC_SX).
727      - remove hard-wiring of CPP-flag ALLOW_SOLVERS_KLOOPINSIDE to
728        ALLOW_AUTODIFF. This flag now needs to be set outside of
729        solve_tri/pentadiagonal.F
730    o pkg/exf:
731      - fix previous modif in exf_readparms.F (revision 1.66: treatment of
732        optional namelist EXF_NML_OBCS).
733      - add many debug-print (to trace down where pkg/cal error msg comes from)
734    o pkg/mom_vecinv/mom_vi_hdissip.F
735      - rearrange loops so that vectorization is improved and in particular
736        the adjoint routine vectorizes. The code is a little longer now, but I
737        think easier to read.
738        Note: CPP-flag MOM_VI_ORIGINAL_VISCA4 is not tested.
739    o pkg/seaice:
740      - allow to specify initial seaice velocity from files (uIceFile,vIceFile)
741    o pkg/exch2:
742      - alternative code (without tile x tile matrix) for cumulated (global) sum;
743        used as default; keep using matrix version in adjustment.cs-32x32x1.
744    o tools/build_options:
745      - after merging some MPI and/or multi-threads specific optfiles so that
746        the modified default optfile support both built (using genmake2 -mpi
747        for the MPI built, using genmake2 -omp for OpenMP built),
748        move now obsolete optfiles to tools/build_options/unsupported/
749       (add copy of email sent to support list in doc/optfiles_changes.txt)
750    
751    checkpoint63c (2011/09/28)
752    o pkg/ebm:
753      - fix ebm_zonalmean.F for several procs in Ydir (nPy > 1); update output of
754        test exp. global_ocean_ebm (affects machine truncation, 12 digits for cg2d)
755    o pkg/seaice (SItracer pickup)
756    * Simple code for pickup of SItracer fields (#define ALLOW_SITRACER)
757      To be done:
758      - thorough testing of missing fields in S/R seaice_read_pickup
759      - thorough matching between generic tracers and specific fields used
760        (e.g. volume-weighted age, area-weighted age, salinity, ...)
761    o pkg/grdchk:
762      - all procs calculate and print finite-difference gradient (for testreport)
763      - change description output used by testreport;
764      - AD testing: also compare and report Finite-difference gradient;
765        => update all output_adm*.txt
766    o test exp. global_ocean_ebm:
767      - switch back useRealFreshWaterFlux (no problem anymore with run-off);
768        and turn on exactConserve; update (fwd) output.
769    o pkg/seaice (LSR):
770      - print to STDOUT number of solver iterations at SEAICE_monFreq interval.
771      - modify solver to deal cleanly with u/v switch at face edges (CS-grid):
772        * identical results with non-CS topology (but save up to half of EXCH calls)
773        * no much changes in cs-32 verification tests since no ice at face edges
774         (differences due to convergence criteria, since nb of iterations changed)
775        * expect some differences on lat-lon-cap grid.
776        update FWD results of global_ocean.cs32x15 test exp. (icedyn & seaice)
777    o pkg/exch2:
778      - add new CPP option to disable Cumul-Sum matrix (to save storage when using
779        many tiles); until alternative coding is added, just add a stop.
780    o pkg/kpp:
781      - move ptracer/salt correction to KPP diffusivity from calc_3d_diffusivity.F
782        to S/R KPP_CALC_DIFF_PTR (+ add tracer-index to argument list).
783    o optfiles:
784      - merged few MPI specific (*+mpi*) and multi-threads specific (*+mth) optfiles
785        into corresponding standard one, which now support different build:
786        (when using "genmake2 -mpi" for MPI built, "genmake2 -omp" for OpenMP built)
787      - add "darwin_amd64_gfortran" optfile (initially from Constantinos, tested by Gael)
788    o pkg/obcs (seaice):
789      - add missing EXCH for uIce,vIce after applying OBCS;
790      - remove S/R EXF_SWAPFFIELDS_X/Y , disable S/R EXF_SET_OBCS_X/Y by adding
791        argument = number of levels to S/R EXF_SWAPFFIELDS_XZ/YZ and S/R
792        EXF_SET_OBCS_XZ/YZ ; update obcs_exf_load.F;
793      - fix EXF_SET_OBCS_XZ/YZ for multi-threaded (assuming loaded arrays are shared)
794      - verification exp. seaice_obcs: split domain in 2 tiles ; add SIZE.h_mpi
795        and eedata.mth for MPI and mutlti-threaded testing.
796    o pkg/flt:
797      - make FLT EXCH working with multi-threads (and MPI + multi-threads);
798      - use buffer for floats IO (trajectories & profiles); size set in FLT_SIZE.h;
799      - fix pickup and trajectories + profiles output with multi-threads;
800      - add parameter to select group of fields to write along trajectory and
801        profile (default unchanged);
802      - only call PORT_RAND* function when flt_noise <> 0;
803      - add multi-threaded test for verification exp. flt_example.
804    o eesupp/src:
805      - fix S/R ALL_PROC_DIE for MPI+multi-threads.
806      - USE_OMP_THREADING: check that number of threads (from eedata) matches
807        actual number (from env.var. setting).
808    o pkg/ebm:
809      - fix multi-threading in ebm_area_t.F ; clean-up EBM.h header file.
810      - add multi-threaded test for verification exp. global_ocean_ebm
811    
812    checkpoint63b (2011/08/29)
813    o pkg/ebm:
814      - fix sign of runoff;
815      - update directly forcing fields (Qnet,EmPmR) to use standard
816        external_forcing_surf.F (remove ebm_forcing_surf.F);
817      - avoid loading forcing fields a 2nd time (1rst time from ini_forcing.F);
818      - set either tauThetaClimRelax (in data) or tauThetaZonRelax (in data.ebm)
819        and apply relaxation towards corresponding SST field (2-D map or ZonAver).
820      - update global_ocean_ebm parameters file data and update output (fwd+ad).
821    o verification/matrix_example:
822      - split domain in 8 tiles (2x4); add SIZE.h_mpi and eedata.mth for
823        MPI and mutlti-threaded testing.
824    o pkg/matrix:
825      - change name of S/R MATRIX_INIT to S/R MATRIX_INIT_VARIA ;
826      - fix for multi-tiles (add bi,bj indices to exp/impMatrixCounter);
827      - fix for multi-threaded (remove DATA statement);
828      - use standard DIFFERENT_MULTIPLE function;
829      - add MATRIX_OPTIONS.h
830    o verification/matrix_example:
831       To allow to split the domain in several tiles, change the domain size
832        from 31x31 to 32x32 by adding 1 row (on Southern side) + 1 column (on
833        Western side) of land points.
834    o (*_)write_pickup:
835      - fix few bugs in mypackage_read/write_pickup.F
836      - in MDS_WR_METAFILES calls, replace "myTime" by a local copy into
837        array of length 1 (was caught by compiler syntax-check).
838    o pkg/diagnostics (velocity potential solver):
839      - fix initialisation of main diagonal matrix (for overlap values)
840    o tools/build_options:
841      - towards single optfile for MPI and non-MPI built: merge few +mpi optfile
842        into previously non MPI one (linux_am64 pgf77,open64,pathf90,ifort11)
843      - linux_amd64_gfortran: merge +mpi_generic version into standard optfile:
844        * move IEEE flags to DEVEL section; take IEEE flags from +mpi_generic ;
845        * FAST case: for now, keep -O3 with ini_masks_etc.F in NOOPTFILES list;
846        and use "-devel" testreport option for standard testing on baudelaire.
847    o pkg/grdchk:
848      - Assume that all gradient-check position are within the same tile
849        corresponding to global indices (iGloTile,jGloTile) and that
850        positions (i,j indices or nbeg) are local to this tile;
851      - set tile local-indices and proc. number according to tile global-indices;
852      - remove grdchkwhichproc from namelist (retired param);
853      - send adjoint gradient to all procs so that all procs print it to STDOUT;
854      - switch on MPI test for global_ocean.90x40x15 AD test experiment.
855    o adding package bbl (Bottom Boundary Layer)
856      description in MITgcm/pkg/bbl/bbl_description.tex
857      example/test experiment in MITgcm_contrib/bbl
858    o adjoint verifications
859      - changed 5 experiments to multi-tiles
860        * global_ocean.90x40x15
861        * obcs_ctrl
862        * offline_exf_seaice
863        * tutorial_dic_adjoffline
864        * tutorial_tracer_adjsens
865        changed reference output for those that crossed tile boundaries
866        (changed choices of gradient check positions)
867      - with same tiling, switch on MPI test for the last 4 (add SIZE.h_mpi)
868      - temporary bug fix in grdchk_loc.F for obcs
869    o genmake2 & testreport
870      - add target "obj" (just for OBJFILES files) to Makefile;
871      - add option to specify FEXTRAFLAGS on command line.
872    o pkg/mypackage:
873      - remove bi,bj arguments from argument list of S/R MYPACKAGE_CALC_RHS
874    
875    checkpoint63a (2011/08/02)
876    o pkg/diagnostics (velocity potential):
877      - fix velocity-potential calculation when using OBCS: balance net inflow
878        at each level (new S/R OBCS_DIAG_BALANCE).
879      - fix some of the problems with OBCS in stream-function calculation.
880    o pkg/exf/exf_readparms.F
881      - make treatment of optional namelists (EXF_NML_04, EXF_NML_SGRUNOFF,
882        EXF_NML_OBCS) more consistent, so that you need not have these lists
883        in data.exf when they are not used.
884    o optim/optim_readdata.F:
885      - add some output about obcs variables that might help debugging
886      - add a check about nvarlength
887    o pkg/ctrl: once again, fix computation of endrec in s/r ctrl_init_rec
888    o pkg/diagnostics (velocity potential):
889      - fix mask for OBCS (still problems in stream-function with OBCS);
890      - add specific parameter (default = main code CG2D params) for solver;
891      - in case of poor convergence, use solution corresponding to lowest residual.
892    o pkg/seaice/seaice_growth.F: small changes that permit vectorizable
893      adjoint code. In general statements like tmpscal=fld(i,j) are problematic
894      and should be avoided where possible.
895    o model/src (rStar):
896      - include r* effect on reference-state (PhiRef) in totPhiHyd
897        (so that it's really the potential anomaly at the cell center);
898        affect solution only if z* with full pressure in EOS.
899      - test-exp global_ocean.90x40x15: reduce viscA4 (was not stable) and
900        update output (because of z* in totPhiHyd and viscA4 changes);
901      - keep the previous diagnostics as "PHIHYDcR" (closer to potential anomaly
902        @ constant r) until interpolation at constant r is implemented.
903    o pkg/diagnostics
904      - fix RCENTER diagnostics in case cell center is not at interface middle
905    o add code for TEOS-10 (www.teos-10.org, McDougall et al. 2011). Use
906      this eos with eosType = 'TEOS10', in data (PARM01). This eos implies
907      that THETA and SALT are "conservative temperature" and "absolute
908      salinity"
909    o pkg/ctrl
910      - fix computation of endrec in s/r ctrl_init_rec
911      - ctrl_pack/unpack_*: remove unused variables and some obsolete code
912    o pkg/seaice/seaice_growth.F
913      - fix recomputation with FENTY_AREA_EXPANSION_CONTRACTION code,
914        remove then obsolete STORE directives
915      - fix STORE directives for tice and tices, so that only the
916        appropriate part of the fields are stored (and not the entire
917        field); update global_ocean.cs32x15.seaice AD output.
918      - cosmetic changes: adjust CPP flags and indentation for better
919        legibilty
920    o pkg/autodiff: add mnc-output of adBottomDragFld (code contributed by
921      Chris Wilson)
922    o pkg/gmredi:
923       Add Sub-Meso Eddies parameterisation from Baylor (for now, disabled with TAF),
924       and test it in verification exp. "front_relax.bvp" (update output.bvp.txt)
925    
926    checkpoint63  (2011/07/11)
927    o pkg/exch2:
928     - rename+move: nTiles in W2_EXCH2_PARAMS.h --> exch2_nTiles in W2_EXCH2_TOPOLOGY.h
929     - exch2 version of Cumul-Sum routine: S/R W2_SET_MAP_CUMSUM set up the
930       (2*nTiles)x(nTiles) Cumul-Sum matrix and Master Proc collects all tiles X,Y
931       increments, calculates Cumul-Sum @ tile origin and sends results to each tile.
932    o pkg/diagnostics:
933     - deal with pairs of post-processed diags which are computed together; in
934       particular, re-order list of diags within 1 file to save 2nd computation.
935     - add S/R to compute velocity stream-function (called after velocity-potential
936       calculation) from divergence free transport -> new diagnostics "PsiVEL".
937     - add parameter to select grid-point location where PsiVEL == 0.
938    o eesupp/src:
939       new S/R to calculate cumulated sum on tiled array, corner grid-cell location
940       (specific S/R needed with exch2 topology - for now, just print an error msg)
941    o pkg/shelfice
942     - Implement friction velocity-dependent transfer coefficients following
943       Holland and Jenkins, JPO, 1999
944       Original code by M. Losch with small modifs.
945       Enable with CPP option SHI_ALLOW_GAMMAFRICT
946       and runtime flag SHELFICEuseGammaFrict
947    o verification lab_sea & global_ocean.cs32x15:
948     - use tools/xmakedepend (instead of cyrus_makedepend, in genmake_local):
949       does not miss some dependencies (but is slower) and also works with many files
950       (default makedepend limitation for AD built).
951     - use cyrus_makedepend in adjustment.128x64x1 (so that it still tested).
952    o pkg/diagnostics:
953     - add run-time parameter "useMissingValue" (def=False) to fill land-point
954        (i.e., where mask=0) with MissingValue ; used only in MNC output file.
955       This replaces CPP-option DIAGNOSTICS_MISSING_VALUE.
956     - Extend the use of "missing_value" setting from data.diagnostics for the case
957       of counter-diagnostics (where fraction-weight is zero). This applies both to
958       MNC and MDS output files.
959    o pkg/seaice/seaice_growth.F:
960      - add 'a priori' cap of latent heat flux based on actual mass considerations
961        when SEAICE_ADD_SUBLIMATION_TO_FWBUDGET is used in conjunction with the
962        non-legacy seaice_solve4temp.
963      - add diagnostic of the residual sublimation freshwater flux (the freshwater
964        flux taken from the ocean if the total actual latent heat fluxes exceed
965        the maximum)
966      - remove the CPP switch around the *_FWbySublim unit change and move diagnostic
967       fill for SIatmQnt, SIfwSubl, SIatmFW to the end of seaice_growth.F.
968      - add diagnostic of the actual sublimation freshwater flux (that is 0. ifndef
969       SEAICE_ADD_SUBLIMATION_TO_FWBUDGET) and of the latent heat flux (evap+sublim).
970      - bug fix : frWtrAtm needs a_FWbySublim ifdef SEAICE_ADD_SUBLIMATION_TO_FWBUDGET.
971      - bug fix : missing part to Martin's r_FWbySublim pathological case fix.
972    o verification 1D_ocean_ice_column:
973       made model domain truly 1x1x23 instead of 5x5x23 with only center cell (3,3,:) wet
974       update results
975    o pkg/diagnostics:
976     - Implement setting of "Post-Processed" diagnostics (corresponding to gdiag(5)='P')
977       which are not filled-up but computed from other diags ; In this case, the mate
978       diag points to the primary (filled-up) diag to used for post processing.
979     - Update Velocity-potential computation using post-processed diag framework.
980     ==> Change the ordering of fields and time-periods in MDS output file
981       when using periodic averaging: now writes one time record with the full set
982       of fields for this time period, then the next time reccord (it used to be
983       one field with the full set of time records then the next field).
984         Note: this is now similar to NetCDF (MNC) output file. <==
985    
986    checkpoint62z (2011/06/21)
987    o adjoint monitor:
988     - Add adjoint monitor output for packages exf, seaice
989       and update relevant testreport output
990    o pkg/seaice:
991     - re-order diags inits so that they appear in order in available_diagnostics.log
992     - added diags: hsnow thermo. rates of change, area preceeding ridiging process,
993       area/heff/hsnow preceeding thermodynamic growth/melt.
994     - modified diag: SIdA; output actual effect, as the description states.
995     - modified description: SIqneti, SIqneto, SIuheff, SIvheff, SIdAb*, HSNOW.
996     - retired redundant diags: SIyneg, SIfice, SIsnwice, SIthdgrh.
997       (SIyneg->SIdHbOCN; SIfice->SIdHbATC; SIsnwice->SIdHbFLO;
998        and SIthdgrh->SIdHbOCN+SIdHbATC+SIdHbATO)
999     - modified diags (2) : switch all SIdA*, SIdH*, SIdS* from delta to rates.
1000     - added diagnostics for seaice generic tracers (SItr*).
1001     - added SItrUnit and SItrNameLong run time param (for SItr* diags).
1002     - in diag names, replaced 'PrTh' abbrev. of 'preceeding thermo' with 'PT'.
1003     I. Fenty: 18-Jun-2011:
1004     Minor changes to seaice package:
1005     1) Retired old variables (A22, SEAICE_lhsublim, areaMax, areaMin, hiceMin) and
1006        added some new ones (SEAICE_area_reg, SEAICE_hice_reg, SEAICE_area_floor)
1007       - Differentiated "regularization variables" from "floor variables"
1008        * areaMin became SEAICE_area_reg (old A22) and SEAICE_area_floor
1009        * hiceMin became SEAICE_hice_reg (old hiceMin)
1010          (with _reg meaning regularization variable)
1011       - SEAICE_lhSublim becomes lhSublim, the sum of SEAICE_lhEvap and SEAICE_lhFusion
1012        so as to ensure energy conservation when going between phases
1013      - A22 was not used anywhere
1014     2) Changed regularization procedure for heffActual and hsnowActual to ensure
1015        well-boundedness and smooth adjoint in seaice_growth.F
1016     3) Fixed a bug where seaice_solve4temp would not recognize ice-free grid cells
1017        because the old regularization always set heffActual >= 0.05 cm
1018     4) Changed the model so that the default behavior is to put a small (10^-5) "floor"
1019        on AREA when HEFF > 0.
1020      - went from requiring ALLOW_PRECLUDE_INFINITESIMAL_AREA to be defined to
1021        requiring that DISABLE_AREA_FLOOR *not* be defined
1022     Affected verifications:
1023      - 1D_ocean_ice_column (output.txt output_adm.txt)
1024      - global_ocean.cs32x15 (output.seaice.txt output_adm.seaice.txt)
1025    o pkg/diagnostics:
1026      - move MNC code from diagnostics_out.F into new diagnostics_mnc_out.F (2 S/R).
1027      - rename S/R GETDIAG to DIAGNOSTICS_GET_DIAG and change type of 1rst argument
1028        (was _RL, now integer) with option = 0 to retrieve all levels.
1029      - add pieces of code to compute velocity potential at each level (new diagnostics
1030        PhiVEL, works only when UVELMASS & VVELMASS are also turned on);
1031        for now, using same params as CG2D (target-resisual, max Nb of iter ...).
1032      - fix few issues with counter diagnostics in diagnostics_setdiag.F &
1033        diagstats_setdiag.F (if diagnostic counter is itself a counter diag)
1034        and in diagnostics_fract_fill.F (do not need a valid pointer for the
1035        diagnostics counter-mate); check that definition of counter-diagnostic
1036        includes a valid counter-mate (in diagnostics_set_levels.F).
1037    o model/src (rStar):
1038      - add rStar scaling factor in diags_phi_hyd.F (similar to calc_grad_phi_hyd.F);
1039        affect solution only if z* with full pressure in EOS;
1040        update output of test-exp global_ocean.90x40x15.
1041    o pkg/seaice:
1042      - introduce siEps=1e-5 parameter
1043      - use areaMax in AREA update (part 4), consistent with ridging step (part 2.5).
1044      - re-organize SEAICE_ADD_SUBLIMATION_TO_FWBUDGET code.
1045      - introduce ALLOW_SITRACER and seaice_tracer_phys.F to handle generic seaice tracer.
1046        For now it covers, and was tested for, ice salinity and age (attached to HEFF),
1047        as well as ice cover age and ridging index (attached to AREA).
1048        For now the run time parameters (in data.seaice/SEAICE_PARM03) are
1049        SItrName (e.g. 'age') and SItrMate ('HEFF', which is the default, or 'AREA').
1050        Up to SItrMaxNum=3 tracers can be used simultaneously.
1051    o pkg/salt_plume:
1052      -introduce SPsalFRAC run time parameter that sets the fraction of the
1053       salt by-product of ice growth (SPsalFRAC*(1-SIsalFRAC)*salt typically)
1054       that gets vertically redistributed (fluxed down) by pkg/salt_plume.
1055    o model debug options:
1056      - Switch reading of debugMode from S/R INI_PARMS (parameter file "data", stored
1057        in PARAMS.h) to S/R EESET_PARMS (parameter file "eedata", stored in EEPARAMS.h).
1058      - Refine debug-msg printing selection (3 new levels):
1059        debugMode  : controls printing of debug messages (sequence of S/R calls).
1060        debugLevel : controls printing of algorithm-relevant auxiliary/debug messages
1061         debLevZero =  0 ; /* level of disabled aux. msg printing */
1062         debLevA =  1 ; /* level of minimum  aux. msg printing */
1063         debLevB =  2 ; /* level of low aux. print (report read-file opening)*/
1064         debLevC =  3 ; /* level of moderate debug prt (most pkgs debug msg) */
1065         debLevD =  4 ; /* level of enhanced debug prt (add DEBUG_STATS prt) */
1066         debLevE =  5 ; /* level of extensive debug printing */
1067        New debugLevel default: with default debugMode value (=F),
1068          = 2 (debLevB) or = 1 (debLevA) in case ALLOW_AUTODIFF is defined.;
1069          and if debugMode=T, default debugLevel = 4 (debLevD).
1070        Relation with previous settings:
1071         debLevB (=2) corresponds to former debLevA (=1)
1072         debLevD (=4) corresponds to former debLevB (=2)
1073        Note:
1074         a) if debugLevel=0, skip WRITE_GRID call when nIter0 > 0 (same as before);
1075         b) default debugLevel=1 is convenient in AD runs (avoid many file opening msgs);
1076            to recover previous default, set debugLevel=2 (e.g. AD-test hs94.1x64x5)
1077      - Add new parameter (printResidualFreq, read from PARM02 namelist) to print
1078        detailed CG solvers convergence; off (=0) by default, except if debugLevel=5.
1079    o pkg/obcs:
1080      - change OBCSfixTopo default from True to False (should not change the results);
1081        keep OBCSfixTopo=T in verification-exp. seaice_obcs.
1082    o pkg/thsice:
1083      - fix bug in thsice_calc_thickn.F (was introduced in version 1.18) in
1084        2nd layer seaice sublimation (unlikely to happen)
1085      - use Interior mask for OBCS in thsice_advection.F (similar to what is
1086        done in gad_advection & seaice_advection).
1087    o adjoint:
1088      bug fix spotted by Gael Forget:
1089      seaice_advection and thsice_advection still had
1090      legacy CPP options to avoid CS corner updates for adjoint
1091    o pkg/seaice:
1092      => Change some of the defaults (2011/05/29):
1093         - change SEAICEuseFluxForm default (from False to True)
1094         - change DIFF1 default (from 0.004 m/s to 0. m/s)
1095         And print warnings if DIFF1 is not set in data.seaice and centered
1096          avection scheme is used without any diffusion.
1097      also:
1098      - fix seaice_diffusion calls in default AdvScheme part of seaice_advdiff.F;
1099      - set SEAICEdiffKh[] default in the same way as SEAICEadvSch[]
1100      - stop if DIFF1<>0 with SEAICEadvScheme <> 2, if DIFF1<>0 with any
1101        other non-zero SEAICEdiffKh[] diffusivity, if SEAICEadvSalt=T with
1102        #undef SEAICE_VARIABLE_SALINITY, if SEAICEadvAge=T with #undef SEAICE_AGE.
1103      update results of test exp.:
1104         lab_sea: output.fd (switch to AdvScheme=33 with diffKh=20)
1105             output.hb87, output_adm.evp (SEAICEuseFluxForm=T and diffKh=200)
1106             output_adm.noseaicedyn (SEAICEuseFluxForm=T)
1107         offline_exf_seaice: output.seaicetd, output_adm (SEAICEuseFluxForm=T)
1108         seaice_obcs: output (SEAICEuseFluxForm=T)
1109      and prescribe old default for SEAICEuseFluxForm (=F) and DIFF1 (=0.004)
1110          for standard fwd & AD lab_sea tests (to keep the same output).
1111    o pkg/seaice/seaice_growth.F:
1112      - use Ian Fenty's capping formulas for actual ice
1113      thickness thoughout EVOLUTION branch.
1114      - put treatment pathological case #2) in CPP brackets
1115      (ALLOW_AVOID_INFINITESIMAL_AREA, undef by default).
1116      - update global_ocean.cs32x15 and 1D_ocean_ice_colum results accordingly.
1117    o pkg/seaice:
1118      - seaice_diffusion.F : remove the min(DX,DY) factor permanently;
1119      pass the Laplacian diffusivity (in m^2/s) diffKh as a parameter;
1120      also pass fac as a param, which can be 1. (to update the tendency
1121      field) or the time step (to update the field itself).
1122      - seaice_advdiff.F: for multidim, call seaice_diffusion with
1123      e.g. SEAICEdiffKhHeff and with fac=1; for single-dim, call
1124      seaice_diffusion with e.g. SEAICEdiffKhHeff and with fac=time step.
1125      - SEAICE_PARAMS.h, seaice_readparms.F, seaice_check.F :
1126      hooks to handle SEAICEdiffKhHeff, SEAICEdiffKhArea, etc.
1127    o pkg/seaice:
1128      diffusion with centered advection scheme (diffus.F & advect.F):
1129      - simplify S/R DIFFUS (put deltaT & DIFF1 factor outside, move EXCH outside)
1130        to just compute the laplacian of input-field.
1131      - unroll k loop (harmonic,biharmonic diff) in advect.F to save 1 exch call.
1132      - fix flux-form version in diffus.F to conserve tracer.
1133      update output of lab_sea.fd & lab_sea.hb87 (1rst set of modif affects
1134       machine truncation) and lab_sea.salt_plume (conservative flux-form modif)
1135    
1136    checkpoint62y (2011/05/26)
1137    o pkg/seaice:
1138     - seaice_growth.F : in EVOLUTION branch, always include
1139       a_QSWbyATM_cover in qnet (as it should be).
1140     - verification/global_ocean.cs32x15 : update results accordingly
1141       (output.seaice.txt output_adm.seaice.txt).
1142    o pkg/seaice + obcs:
1143     - use maskInW & maskInS in multi-dim advection and biharmonic diffusion:
1144       equivalent of assuming no tracer gradient outside the OB region.
1145       update output of seaice_obcs (uses DIFF1 <>0 => biharmonic diffusion)
1146     - remove calls to OBCS_COPY_TRACER after EXCH calls (no longer needed
1147       after changes above);
1148     - obcs+seaice cleaning: apply seaice-tracer OB values to tracer field
1149       only at OB location (instead of over a band of OLx width).
1150    o pkg/seaice:
1151     - fix wrong indices in old (non Flux-Form) diffusion default S/R diffus.F
1152       (dxG(I+1, ...) changed to dxG(I, ...), no impact on Lat-Lon grid)
1153    o pkg/obcs:
1154      - split header file "OBCS.h" into 4 separated files:
1155        OBCS_PARAMS.h, OBCS_GRID.h, OBCS_FIELDS.h & OBCS_SEAICE.h
1156       Note: OBCS_PARAMS.h & OBCS_GRID.h can be included without OBCS_OPTIONS.h
1157         (contain no conditional statement which depends on OBCS options).
1158      - move "useOBCSYearlyFields" from "data.obcs" (hold in OBCS_PARAMS.h)
1159        to parameter file "data.exf", namelist EXF_NML_OBCS (in EXF_PARAM.h).
1160    o ctrl, cost, grdchk & autodiff pkgs:
1161      - make options file more standard (like other {PKG}_OPTIONS.h file but
1162        with AD_CONFIG.h); clean-up some of the included header files.
1163    o pkg/obcs:
1164      - do not mask tracer when applying OB (tracer == 0 could generate problems)
1165      - apply tracer OB values to tracer field only at OB location (instead of
1166        over a band of OLx width)
1167      - clean-up obcs_apply_w.F & obcs_apply_eta.F (since less calls to these S/R)
1168      - remove OBCS_MULTIDIM_OLD_VERSION code in gad_advection.F and remove
1169        obcs_apply_tloc.F & obcs_apply_sloc.F
1170    o obcs in model/src:
1171      - call OBCS_APPLY_W only if NonHydrostatic.
1172      - call OBCS_APPLY_ETA only if NonLinFreeSurf.
1173      - reset dEtaHdt and wVel to zero outside OB interior region ;
1174      - leave tracer unchanged outside OB interior region: This has no effect
1175        on the solution but just to prevent unrealistic tracer value outside OB.
1176      - zero out velocity outside OB interior region: This has no effect on
1177        the solution but just to prevent unrealistic velocity outside OB.
1178    o obcs and non-lin free-surf:
1179       move call to OBCS_APPLY_R_STAR from update_r_star.F to calc_r_star.F
1180       and call to OBCS_APPLY_SURF_DR from update_surf_dr.F to calc_surf_dr.F
1181       + add argument "etaFld" to OBCS_APPLY_R_STAR & OBCS_APPLY_SURF_DR:
1182       this fixes missing EXCH + get consistent eta OB value (+ fix restart).
1183       update results of test-exp. exp4(nlfs).
1184    o exp4 (nlfs) test-exp:
1185       use OBC for Eta at Western & Eastern OB (to test prescribing Eta
1186       with NonLin-FreeSurf); update output.nlfs.txt
1187    o obcs and 2d/3d solver norm:
1188       use interior masks (maskInC) to cancel out cg2d & cg3d matrix coeff at OB
1189       and outside OB interior region (will allow to place OB further inside the
1190       domain). Depending on the domain, can affects cg2d-Norm (previous
1191       cancellation outside OB was only partial), e.g. in exp4 & obcs_ctrl,
1192       and cg3d-Norm (previous Norm was computed before canceling OB terms),
1193       e.g. in tutorial_plume_on_slope.
1194      - update output of exp.: exp4 (x2), obcs_ctrl and tutorial_plume_on_slope.
1195    o pkg rbcs:
1196      - split RBCS.h into 3 files: RBCS_SIZE.h, RBCS_PARAMS.h & RBCS_FIELDS.h
1197      - add capability to apply relaxation to horizontal velocity uVel & vVel.
1198    o pkg/grdchk: add gradient check for control variable xx_shifwflx
1199    o pkg/shelfice/shelfice_init_fixed.F
1200      fix CPP-flag combinations
1201    o pkg/seaice: Merge iceage code of Pierre Rampal
1202      * update/change/correct ice age calculations
1203      * add age updates for pathological cases
1204      Probably needs more testing...
1205    
1206    checkpoint62x (2011/05/13)
1207    o pkg/mom_vecinv:
1208       high-order vorticity scheme: use interior masks (maskInW & S)
1209       to zero-out (outside OB) gradient of vorticity.
1210    o verification exp.:
1211       turn on "useEnergyConservingCoriolis" (better discretisation) in exp.
1212       hs94.128x64x5 and seaice_obcs ; update results.
1213    o pkg/obcs:
1214      fix bug in OBeta for YZ sections in obcs_exf_load.F
1215    o pkg/ctrl, pkg/shelfice, and optim:
1216      - add new control variable xx_shifwflx (fresh water flux underneath ice
1217        shelves). This is almost as tedious as obcs-ctrl, because the
1218        variables needs its own mask.
1219      - add a cost function term that penalizes the deviation of xx_shifwflx
1220        from the first guess (zero) in analogy to other control variables
1221    o pkg/shelfice:
1222      - start basic adjoint
1223    o pkg/ctrl:
1224      - remove extra 2D field "for good measure" when initializing in
1225        ctrl_set_globfld_[xy/xz/yz].F
1226      - replace hard coded precision 32 (a bug) in ctrl_map_ini_gen by ctrlprec
1227      - improve error messages in ctrl_set_unpack_*
1228    o OBC implementation in momentum:
1229       use interior masks (maskInC,W & S) in momentum S/R:
1230       - multiply divergence, tension and some del^i.u or del^j.v by maskInC
1231       - multiply del2u,del2v by maskInW/S (biharmonic viscosity)
1232       - multiply horiz. grad of vorticity by maskInW/S (in Leith scheme)
1233       - multiply gradient of wVel by maskInW/S in del2w calculation (NonHyd)
1234       Motivation: fix/clean implementation of OBC with biharmonic-viscosity
1235        (and also with Leith/Smagorinsky harmonic-viscosity).
1236       Update output of experiment dome and exp4 (+nlfs).
1237    o exp4 test-exp:
1238      - turn on: nonHydrostatic, exactConserv, viscA4 (with momDissip_In_AB=F)
1239        and prescribe time-varying OB (without pkg/exf) for zonal-velocity
1240        at Western & Eastern Boundaries (+/- 1 per-cent); Also prescribe
1241        time-varying OB at Western-side for wVel (NonHyd); update output.
1242      - add secondary set-up (.nlfs) using NonLin FreeSurf (z*) + mom_vecinv
1243        and biharmonic-viscosity ; also use prescribed time varying OB.
1244    o pkg/obcs:
1245      fix bug in OBWeta,OBWeta indices in obcs_apply_r_star.F
1246    o model/src:
1247      - fix startTime setting when baseTime<>0 & nIter0=0 are specified ;
1248      - initialise startTime & nIter0 with unlikely values: allows to set one
1249        from the other without ambiguity.
1250    o seaice_obcs test-exp.:
1251      add small diffK4T,S to test biharmonic diffusivity with OBCS ; update output.
1252    o pkg/obcs:
1253      - remove calls to OBCS_COPY_TRACER after EXCH for T,S & pTracer:
1254        no longer needed with maskInC,W,S in pkg/generic_advdiff.
1255    o pkg/seaice:
1256      - retired SEAICE_SALINITY and SEAICE_salinity in favor of
1257        SEAICE_VARIABLE_SALINITY and SIsalFRAC, respectively.
1258      - fixed bug in the initialization of sea ice salinity variable HSALT
1259        in seaice_init_varia.F  (removed dependence on ICE2WATR)
1260    o fizhi-cs test exp.:
1261       switch reference output convention for these 2 non-standard test-exp,
1262        from: pgi  6.1-5 on faulks (FC.6, -of linux_ia32_pgf77+authors_fc5)
1263          to: ifort 11.1 on baudelaire (FC.13, -of linux_amd64_ifort11)
1264       reason: faulks might get retired soon and pkg/fizhi has still Pb with gfortran
1265    o model/inc:
1266      - change type of PmEpR array (from _RS to _RL) to fix restart (with "-use_r4")
1267        of exp. global_ocean.90x40x15 (Suncronous time-stepping + Real-FW + NonLin-FS)
1268    o pkg/seaice:
1269      - fix calculation of saltFlux and saltPlumeFlux when using SEAICE_SALINITY
1270    o verification/lab_sea, 1D_ocean_ice_column, seaice_obcs, global_ocean.cs32x15
1271      - updated output*.txt files due to bug fixes in salt, saltPlumeFlux,
1272        and initial HSALT
1273    
1274    checkpoint62w (2011/04/26)
1275    o pkg/mom_fluxform:
1276      - fix calculation of del2u & del2v (no-slip BC) when using Non-Lin Free-Surf.
1277      - use parameter "sideDragFactor" in no-slip BC side-drag part.
1278      - update output of exp. global_ocean.90x40x15
1279    o pkg/mom_vecinv:
1280      mask del2u & del2v (no effect on results, but cleaner & closer to mom_fluxform)
1281    o update seaice exp.:
1282      use more consistent parameter values (remove "backward compatability only":
1283       ICE2WATR, SEAICE_lhSublim, SEAICE_cpAir, SEAICE_rhoAir + set rhoConstFresh)
1284      related to thermodynamics seaice. Update output (fwd+AD) of exp.:
1285       1D_ocean_ice_column (x2), lab_sea (x8), ioffline_exf_seaice (x2) & seaice_obcs
1286    o update test-exp global_ocean.90x40x15:
1287      o use default CD_CODE_OPTIONS file (Adams-Bashforth on CD Mom & Coriolis).
1288      o increase Overlap size from 2 to 3 (to allow to test bi-harmonic Visc.)
1289      o new pickup-files from a 100.yr run with pkg/down_slope (input.dwnslp params)
1290      o turn on zStar & viscA4 in standard set-up (dir input/)
1291        and update output files: output.txt & output.dwnslp.txt
1292    o new AD-test experiment: obcs_ctrl
1293      (From Matt MITgcm_Contrib/SOSE/BoxAdj) to test OBCS as control vector.
1294    o pkg/dic:
1295      fix two bugs in handling water vapour pressure in carbonate chemistry
1296      and air-sea fluxes. Found by Val Bennington and Galen McKinley
1297      (add DIC Option = WATERVAP_BUG to recover old results)
1298      update output of tutorial_global_oce_biogeo (fwd+AD) & tutorial_dic_adjoffline
1299    o adding allowInteriorFreezing option to check for water below freezing point
1300      at depth and bring the negative heat anomaly to the surface level
1301    o pkgs _fields_load:
1302      - extend GET_PERIODIC_INTERVAL to deal with non-periodic case (from pkg/rbcs)
1303      - use new S/R GET_PERIODIC_INTERVAL in pkgs:
1304        bulk_force, cheapaml, cfc, dic, obcs (+ ctrl/ctrl_get_gen_rec), offline and
1305        rbcs to get interpolation weights and time reccord number.
1306      - fix multi-threading in aim_fields_load.F
1307      - apply EXCH to temp arrays [0,1] after reading in dic_fields_load.F
1308    o external_fields_load:
1309      new S/R GET_PERIODIC_INTERVAL to calculate which time-record (and linear
1310       interpolation weights) to use in a periodic time-series ; do not divide by
1311       time-step to convert to integer:
1312       - this fixes case where externForcingPeriod is not multiple of time-step
1313          (Thanks to Christopher L. Wolfe)
1314       - this fixes case where externForcingPeriod is an odd multiple of time-step
1315         (was wrong by half of time-step); update results of tutorial_global_oce_in_p.
1316      store index of time-record which is currently loaded:
1317       - works without any assumption on sequence of calls to EXTERNAL_FIELDS_LOAD ;
1318       - needed for the adjoint but not yet used because of extensive recomputations;
1319         (to be fixed soon)
1320    
1321    checkpoint62v (2011/04/02)
1322    o verification/1D_ocean_ice_column added to test Ian Fenty's
1323      pkg/seaice_growth.F modifications for improving sea ice code differentiability
1324    o update output of exp4, internal_wave, seaice_obcs, tutorial_plume_on_slope
1325      (new velocity statistics after changing maskInW & maskInS definition)
1326    o pkg/generic_advdiff with OBCS:
1327      use maksInW & maskInS in advective flux and in biharmonic diffusion calculation:
1328      equivalent to assumption of no tracer gradient outside the OB region.
1329      This will affect the results if using obcs+biharmonic diffusion.
1330      update output_adm.txt of experiment bottom_ctrl_5x5 (not expected since no obc)
1331    o pkg/obcs:
1332      change definition of maskInW & maskInS: leave OB edges inside (maskIn=1)
1333      (e.g., maskInW(OB_Ie)=1 ) so that velocity normal-component at OB is still
1334      in Interior region. No impact on solution but affects Velocity monitor stats.
1335    o pkg/ptracers (adjoint)
1336      New option AUTODIFF_PTRACERS_SPLIT_FILES for writing separate
1337      tape file for each tracer
1338    o model/inc/src and pkg/autodiff: add parameters that allow to turn
1339      of parts of the adjoint code at run time. For now, there are only
1340      useKPPinAdMode, useGMrediInAdMode, and useSEAICEinAdMode. These
1341      parameters are set in data.pkg.
1342      This is the lazy coward's version of doing this, but still useful for
1343      debugging. In order to do it right, everything needs to be moved to
1344      pkg/autodiff.
1345    o pkg/autodiff: fix global_sum_tile_ad.F by resetting adsumPhi at
1346      the end; this fixes the adjoint balancing code for open boundaries.
1347    o pkg/ctrl:
1348      - change behavior of xx_${varname}period to be analogous to exf-conventions:
1349        xx_${varname}period =   0.,  means time-independent control part
1350        xx_${varname}period = -12., means one-year-periodic monthly control part
1351      - introduce helper routine ctrl_init_rec (part of ctrl_init.F) to
1352        clean up ctrl_init a little, remove unused variables
1353      - ctrl_init: fixed the handling of the start/endrec for obcs-variables
1354      - move "call cal_GetMonthsRec" from s/r ctrl_get_gen to s/r ctrl_get_gen_rec
1355    
1356    checkpoint62u (2011/03/15)
1357    o model/src:
1358      - for the adjoint, change NonLin-FreeSurf initialisation sequence: fill-in
1359        h0Fac from INITIALISE_FIXED and reset hFac to h0Fac in INITIALISE_VARIA ;
1360      - in initialise_varia.F (except for ALLOW_DEPTH_CONTROL) remove 2nd call to
1361        INI_DEPTHS, INI_MASKS_ETC & INI_LINEAR_PHISURF.
1362    o pkg/ctrl/obcs/ecco:
1363      - remove obsolete, unused, and partially broken code:
1364        ctrl_obcsvol/ctrl_obcsbal/ctrl_volflux and code within
1365        ALLOW_CTRL_OBCS_BALANCE
1366      - put a stop statement into ecco/cost_obcsvol.F, but also add
1367        cost_obcsvol to ecco_ad_diff.list
1368    o pkg/ecco: fix counting cost function contributions for obcs (code
1369      by Matt M.) and diffkr for diagnostics
1370    o pkg/ecco, pkg/ctrl, pkg/grdchk:
1371      add cost penalty terms for initial uvel, vvel, eta controls
1372      and I/O for prior error files
1373    o pkg/mdsio:
1374       move mds_check4file.F from eesupp/src to mdsio_check4file.F ; add option
1375       (new argument) to check for tiled file in mdsioLocalDir : this fix the
1376       restart from pickup_som , pickup_dic (& dic_co2atm) with mdsioLocalDir.
1377    o pkg/ctrl:
1378     - ctrl_obcsbal.F, ctrl_obcsvol.F: replace last calls of ctrl_getrec by
1379       ctrl_get_gen_rec, put a stop statement into ctrl_getrec. Remove
1380       unused and superfluous variables
1381     - ctrl_get_gen_rec.F: catch the case of xx_genperiod=0.
1382    o pkg/ecco
1383     - enable adjoint of Stevens OB
1384    o pkg/ctrl/ecco/grdchk:
1385      - remove global declaration of tmpfldx/yz and tmpfldx/yz2.
1386        Fortunately, we do not have any tests for the numerous cpp-flagged
1387        option of "obcs as control parameters" so we will never know
1388        if this is an improvement (but at least now things compile).
1389      - remove an obsolete initialization from ecco_cost_init_barfiles.F
1390      - fix some problems within never used ifdefs to make the code compile
1391    o pkg/obcs:
1392     - Refine Interior mask definition to work with more complex OB (e.g.
1393       if OB_Ie < OB_Iw); In case default setting is not sufficient, allows to
1394       read in Interior mask from file. Check if Interior mask is consistent
1395       with OB list of indices.
1396    o pkg/seaice
1397     - beginning code for a seaice tracer package,
1398       but currently only used for seaice age: SEAICE_AGE
1399       SEAICE_num = 4
1400       iTracer = 1: area-weighted ice age
1401               = 2: volume-weighted ice age
1402               = 3, 4: template for one-year vs. multi-year ice
1403       data.seaice has new namelist SEAICE_PARM03 for arrays related to
1404       SEAICE_num
1405    
1406    checkpoint62t (2011/03/05)
1407    o pkg/obcs:
1408     - obcs_apply_uv.F: change to a 2 steps method, first tangential component;
1409       then normal component. This ensures that the normal component is set
1410       correctly even when it conficts with tangential setting from an other OB.
1411       Affects results of test-experiment seaice_obcs: update the output.txt
1412    o pkg/obcs:
1413     - add code to monitor statistics of dynamical fields at OB.
1414     - take OBCS_BALANCE code out of obcs_calc.F into new S/R OBCS_BALANCE_FLOW :
1415       - fix to OBCS_BALANCE code (right hFac ; deal with simple OB intersection).
1416       - change default: balance the Net inflow through all OB (instead of balancing
1417         each OB separately); keep the old method if setting OBC_balanceFacX < 0.
1418     - switch on useOBCSbalance in dome experiment: only correct Western OB outflow
1419       to match Nortern OB inflow (OBCS_balanceFacN=0).
1420    o pkg/seaice:
1421     - redefined actual sea ice age to be ICEAGE/HEFF ifdef SEAICE_AGE_VOL
1422    o pkg/seaice (seaice_growth v 1.113):
1423     - reverting seaice_growth to v 1.111 in order to have code with exact bit
1424       compatibility with MITgcm_contrib/ifenty/Fenty_seaice_thermo_code_merge
1425       CPP option SEAICE_OCN_MELT_ACT_ON_AREA removed in v 1.112 is reintroduced
1426       runtime flag SEAICEareaFormula is kept but is inactive
1427    o model/src:
1428     - add new param to scale curvilinear grid distance and area when using
1429       a different sphere radius from the grid-files.
1430     - test/check multi-threads EXCH applied to local variable (cg2d_x)
1431    o adjoint:
1432     - enable adjoint of Stevens OB
1433     - add dummy_in_dynamics to enable extraction of ADJrhoinsitu
1434       (a bit delicate because of potentially modified adj. common block structure;
1435       current switch is ALLOW_AUTODIFF_MONITOR_DIAG, could be changed later)
1436    
1437    checkpoint62s (2011/02/15)
1438    o pkg/seaice (seaice_growth v 1.112):
1439     - introduce SEAICEareaFormula run time parameter, which selects the recipe for
1440       computing the ice cover tendency from effective thickness tendencies. Include
1441       Ian Fenty's formula.
1442     - remove 'undef SEAICE_OCN_MELT_ACT_ON_AREA' which may now be achieved using
1443       SEAICEareaFormula.
1444     - simplify notations for the various d_HEFF/d_AREA terms.
1445    o pkg/gmredi:
1446     - add Boundary-Value-Problem bolus transport (Ferrari etal, OM 2010) code
1447       from Christopher Wolfe (UCSD); add partial cell factor in vertical derivative;
1448       add a verification test-run (front_relax.bvp) to test GM_useBVP.
1449    o pkg/seaice (seaice_growth v 1.111):
1450     - for SEAICE_DO_OPEN_WATER_GROWTH, replace Gael's implementation with Ian's.
1451     - the new SEAICE_DO_OPEN_WATER_MELT allows open-water air-sea heat fluxes to
1452       also melt ice.
1453    o pkg/seaice:
1454     - McPhee formula for Ice-Ocean fluxes (provided by Ian Fenty).
1455     - can be used by #define MCPHEE_OCEAN_ICE_HEAT_FLUX in SEAICE_OPTIONS.h
1456    o pkg/cheapaml:
1457     - from Nico Wienders: New version of this package.
1458    o pkg/flt:
1459     - add CPP options to prevent floats to re-enter the opposite side of
1460       a periodic domain (default: keep periodicity)
1461    o pkg/gmredi:
1462     - apply exchange to GM_PsiX,GM_PsiY to get valid values near CS-corners
1463       (needed for multi-dim advection).
1464     - switch on GM Advective form in global_ocean.cs32x15 and update output.txt
1465    o model/src:
1466     - fix wrong re-setting of addMass array (ALLOW_ADDFLUID) for atmospheric run.
1467    o tutorial_tracer_adjsens
1468     - extend to NLFS and replace maskC by hFacC
1469       (change reference output accordingly)
1470    
1471    checkpoint62r (2011/01/24)
1472    o testreport:
1473     - add option -deloutp (-do) to remove output file after successful run
1474     - add option -mfile (-mf) for MPI machile-file and for each test-exp,
1475       extract exact list of procs from this file ; adjust COMMAND by
1476       replacing TR_MFILE & TR_NPROC with local machile-file & Nb of MPI procs.
1477    o pkg/ecco: replace old ineffective way of penalizing deviations from
1478      first guess (of obcs) with code by Matt Mazloff
1479    o pkg/ctrl: add code that allows the use of ALLOW_OBCS?_CONTROL without
1480      exf/cal
1481      - ctrl_init: fix initialisation (computation of diffrec) for obcs-ctrl
1482        and handle case of obcs?period == 0
1483        Not affected by these changes: There is still an inconsistency in
1484        the computation of start/endrec for the obcs variables for ALLOW_CAL
1485        defined (see comment by Menemenlis, 7-Mar-2003)
1486      - make S/R ctrl_get_gen_rec return something meaningful even if
1487        ALLOW_CAL is not defined
1488      - ctrl_getobcs?: simplify code so that it does not need to use
1489                       S/R exf_swapfields
1490    o testreport:
1491       allow to test MPI with different number of processors for each experiment:
1492       create file "SIZE.h.mpi" in each build dir.
1493       Note: update of "-command" argument not yet implemented.
1494    o model/src, pkg/autodiff, pkg/ecco, pkg/seaice:
1495      alleviate the need for additional 3D tapes when using
1496      the non-inear free surface in the adjoint. This is done
1497      by adding an 'update' of hfacc etc. to their current
1498      value at the beginning of forward_step.F.
1499    o pkg/seaice
1500      seaice_lsr: move stress-divergence computations out of outer pseudo-
1501      timestepping loop
1502    o pkg/obcs/obcs_prescribe_read.F: move 'CALL OBCS_EXTERNAL_FIELDS_LOAD'
1503      up, so that the calls of the ctrl_* subroutines are really at the end
1504      of the routine.
1505    o pkg/gmredi:
1506      allow to specify a 2-D horizontal map and a 1-D vertical profil
1507      as scaling factor for Isopycnal diffusivity (Redi) and GM diffusivity.
1508    o pkg/seaice:
1509      move lsr iterations from seaice_dynsolver to seaice_lsr.
1510    o pkg/seaice:
1511      reduce memory footprint of seaice mutldim advection tapes,
1512      by using a 2D tape independent of the generic_advdiff ones,
1513      and setting GAD_AREA=1 etc. rather than GAD_AREA=101 etc.
1514    
1515    checkpoint62q (2010/12/29)
1516    o model/src:
1517      - check horizontal grid-spacing for unset or zero/negative values.
1518      - change AD test hs94.1x64x5 to be truly a 2-D set-up.
1519    o pkg/flt:
1520      - use (recent) mdsio S/R MDS_READVEC_LOC instead of local FLT_MDSREADVECTOR
1521      - precision of input and output files set according to readBinaryPrec
1522        and writeBinaryPrec (previously always 64.b), pickup remains at 64 bits.
1523      - initial float position from tiled file was not converted to index space
1524        (looks like a bug): fixed to make it similar to initial pos. global file.
1525    o global_ocean.cs32x15:
1526       change SIZE.h of AD set-up to get same tiling as with MPI.
1527       Update output_adm, output_adm.thsice (pass@14) & output_adm.seaice (fail@11)
1528    o model/src:
1529       add flag to control printing of domain fields (bathymetry, hFac ...) in
1530       ini_mask_etc (call to plot_fieds_xy*).
1531    o pkg/thsice:
1532       if useEXF, some forcing fields are not valid in overlap: fixed by computing
1533       over the interior only + apply EXCH at the end (like with SEAICE advection).
1534    o pkg/mdsio:
1535      - add 2 arguments to S/R MDS_PASS_R4/8toRL/S for overlap size of buffer
1536        to copy to/from, so that it can be used to replace MDS_PASS_WH_R8toRL/RS.
1537      - change barrier call for safe multi-threads access to 3-D shared buffer.
1538      - MDS_READ/WRITEVEC_LOC use buffers from MDSIO_BUFF_3D.h (instead of local ones)
1539      - replace call to MDS_PASS_WH_R4/8toRL with call to MDS_PASS_R4/8toRL and
1540        remove the 4 S/R MDS_PASS_WH_R4/8toRL/S.
1541    o pkg/flt:
1542      - add fourth-order Runge-Kutta integration
1543      - add basic exch2 support (only 1 facet supported so far!)
1544    o pkg/mdsio+rw:
1545      new S/R to read local (or tile independent) vector (read counterpart of
1546       mds_writevec_loc, and front-end write_glvec_rl/rs).
1547    o global_ocean.cs32x15: additional input_ad.seaice experiment
1548        that uses pkg/seaice rather than pkg/thsice.
1549        (using multidim advection for seaice)
1550    o towards more F95 syntax for array specification in namelist:
1551      - change "data.diagnostics" (data.ptracers was changed before checkpoint62p)
1552        of all verification experiments.
1553           e.g.:    line: fields(1,3)='ETAN    ','ETANSQ  ',
1554          was changed to: fields(1:2,3)='ETAN    ','ETANSQ  ',
1555      - finish adding "-DNML_EXTENDED_F77" to DEFINES list in pgf77 and g77 optfiles
1556    o global_ocean.cs32x15: additional input.seaice experiment
1557        that uses pkg/seaice rather than pkg/thsice.
1558    
1559    checkpoint62p (2010/12/17)
1560    o pkg/thsice: rename (ad tape index) iicekey as ticekey, and move it
1561        to THSICE_SIZE.h to avoid conflict with pkg/seaice.
1562    o pkg/seaice: add seaice_diffusion.f seaice_map_thsice.f to adjoint.
1563        allow for use of multim. advection in seaice adjoint.
1564    o pkg/seaice: add diagnostics for snow precipitation and sublimation flux
1565      - first attempt to close budgets by taking into account the freshwater
1566        flux implied by the sublimation of snow and ice. So far only the
1567        volume budget is closed, turn on with soon-to-be-retired-again CPP-Flag
1568        SEAICE_ADD_SUBLIMATION_TO_FWBUDGET
1569    o eesupp/src:
1570      new S/R with new option (NML_EXTENDED_F77) to change array specification
1571      from F95 standard to commonly accepted extended F77 form.
1572      This would allow to use F95 syntax in namelist (needed with gfortran 4.4.5)
1573      and to revert back to the original syntax (with -DNML_EXTENDED_F77)
1574      for less tolerant f77 compiler (e.g., pgf77, g77).
1575    o globalFiles:
1576      commented out in parameter file "data" since it's not safe with MPI
1577      (e.g., wrong on aces); keep it if useSingleCpuIO=T (but not doing much
1578      in this case); no longer commented out in restart test (tst_2+2).
1579    o add adTapeDir to specify a special directory where adjoint tapes are
1580      written/read (adread_adwrite.F). adTapeDir is specified in data/PARM05
1581      and cannot be used together with mdsioLocalDir.
1582    o nesting pkgs:
1583      - packages_init_variables : put call to OBCS_INIT_VARIABLES in last position
1584      - update Gianmaria's Nesting pkgs (from Contrib/nesting_sannino)
1585      - add parameter files + utils dir + output from short run on beagle.
1586    o pkg/seaice:
1587        fix seaice_growth.F store directives; update results of exp. lab_sea.ad
1588    o pkg/seaice: explicitly store tsurfloc in seaice_solve4temp.F to avoid
1589      unnecessary copying in adjoint code, requires new parameter NMAX_ITER
1590    
1591    checkpoint62o (2010/11/25)
1592    o pkg/exf:
1593      - change CPP option EXF_VERBOSE to run-time logical param exf_verbose.
1594    o pkg/seaice:
1595      - seaice_ocean_stress: split a loop for better vectorization of the
1596        adjoint code
1597      - seaice_growth.F: fix bug in conservation of freshwater connected to
1598        capping of heff, put contribution into d_HEFFbyNEG
1599      - replace irritating parameters SEAICE_latentWater/Ice and SEAICE_sensHeat
1600        by something more sensible (parameters that are what their name implies)
1601      - change some defaults, so that by default exf-parameters are used for
1602        things like rhoAir, cpAir,latent/sensible heat parameters, in order
1603        to reproduce the old results, many data.seaice now contain funny values
1604        for cpAir and latent heat of sublimation
1605    o packages_readparms.F: move exf_readparms up in line so that
1606        exf-parameters are visible for other packages (e.g. seaice)
1607    o debugMode & debugLevel=2:
1608      - differentiate between debugMode & debugLevel=2:
1609        debugMode: controls printing of debug messages (sequence of S/R calls).
1610        debugLevel: controls printing of algorithm intermediate results and stats.
1611      - remove "if debugLevel=2 => debugMode" but keep "debugMode =>  debugLevel=2";
1612        => allows to print debug-stats without all sequence of call messages.
1613      - switch control of debug print from debugLevel to debugMode in many S/R.
1614    o pkg/obcs (obcs-sponge):
1615        fix bug that was introduced on Oct 25 (in dynamics.F v1.151): put back the
1616        call to OBCS_PRESCRIBE_EXCHANGES (need to exch gU,gV when using obcs-sponge)
1617    o pkg/generic_advdiff:
1618      - record overlap minimum size for each advection scheme;
1619      - refine criteria on overlap minimum size;
1620      - check and stop (in gad_check) if overlap size is too small.
1621    o pkg/obcs:
1622      - with ptracers: remove multiple calls to obcs_apply_ptracer (only done
1623        once, in ptracers_implicit.F)
1624      - with seaice: remove test on empty file name in obcs_apply_seaice (always
1625        apply OB values when tile has OB)
1626    o model/src, coriolis setting:
1627      - integer parameter "selectCoriMap" (=0,1,2) replaces 3 logical
1628        useConstantF, useBetaPlaneF, useSphereF ; can now read coriolis from
1629        files (selectCoriMap=3) with any grid.
1630      - add parameter "fPrime" for constant second Coriolis coeff (default=0).
1631    o pkg/seaice/seaice_growth.F:
1632        a few cosmetic changes that reduce the number of lines of code
1633    o pkg/obcs: add boundary conditions following Stevens (1990)
1634      - the code follows old MOM/NAOSIM code
1635      - so far it is only implemented for the eastern and western boundaries
1636        and NOT for pTracers
1637    o pkg/rbcs:
1638      - replace rbcsInIter by rbcsForcingOffset, the time in seconds at the
1639        beginning of the first rbcs forcing period.
1640      - add option rbcsSingleTimeFiles that makes rbcs read forcing data like the
1641        offline package, i.e., one file per time, labeled by iteration number;
1642        deltaTrbcs sets the timestep with which the data was generated;
1643        rbcsIter0 is the forcing iteration corresponding to rbcsForcingOffset.
1644      - rbcsForcingCycle=0 makes forcing non-cyclic.
1645      - make arithmetic safe for negative times and odd forcing periods.

1648    o pkg/seaice:
1649        fix masking in free-drift S/R ; update results of exp. lab_sea.fd
1650    o pkg/obcs:
1651       New S/R to copy tracer value from the OB location to narrow band region
1652        (width = same as overlap) beyond the OB: preserve OB value (needed for
1653        high-order scheme) which were overwritten by EXCH call if in overlap
1654        region. Applied to theta, salt, ptracer and advected seaice variables.
1655       With seaice: use maskInC in similar way as in gad_advection.F,
1656        in seaice_advection.F and advect.F.
1657       Update output of experiment seaice_obcs and change exp4 to test OBCS with
1658        4th order Adv.Scheme. for pasive salt and ptracer.
1659    o tools/genmake2:
1660      - when looking for an optfile (not specified), only search for Fortran compiler
1661        (remove sym-link test + setting of CPP + makedepend check + C-compiler check)
1662      - in get_fortran_c_namemangling: use "$CC $CFLAG" to compile C test programm
1663        (instead of "$MAKE genmake_test.o" since an existing Makefile can be wrong)
1664      - set default for CPP to "cpp -traditional -P" (was the case without specifying
1665        an optfile, but otherwise default was just "cpp".
1666      - comment out PLATFORM=$p_PLATFORM (no idea where p_PLATFORM comes from)
1667      - when "CC" is not set in the optfile, look for possible C compiler
1668        (instead of just setting CC=cc)
1669      - put back version v.169 modif (from 2008/02/15), was dropped in v.173 changes:
1670        => add a ".F" to ".o" rule for source files with no "#include" (such as
1671           port_rand.F); otherwise, default ignores FOPTIM and just uses FFLAGS.
1672      - move gfortran before g77 in list of possible Fortran compiler (consistent
1673        with reference compiler switch from g77 to gfortran)
1674    o pkg/seaice:
1675      o remove SEAICE_OLD_AND_BAD_DISCRETIZATION-code, add a test to
1676        seaice_check that stops the model, when the CPP flag is used.
1677      o seaice_growth.F: make capping of ice volume conserving by returning the
1678        capped ice as freshwater to EmPmR. This does not change the verification
1679        experiments but will change runs where the capping is acutally active
1680    o change reference platform+compiler from faulks+g77 to baudelaire+gfortran
1681      (except the 2 fizhi test exp.); update output of exp.: bottom_ctrl_5x5,
1682         global_ocean.cs32x15 (icedyn, thsice, AD thsice), global_ocean_ebm (AD),
1683         lab_sea (fd, hb87, salt_plume), MLAdjust (3/5) and vermix (dd)
1684    o tools/genmake2:
1685      - merge genmake_warnings & genmake_errors into 1 log file: "genmake.log")
1686      - change DUMPSTATE default to false (can use "-ds" option to switch it to T)
1687      - clean previous genmake log files before anything else.
1688      - change Makefile to remove testreport log files (*.tr_log) and genmake log
1689        files only with "CLEAN" target (instead of "Clean");
1690    o pkg/generic_advdiff:
1691      Change OBCS in multiDim advection (gad_advection.F):
1692       Use maskInC to prevent intermediate update of tracer-field in OB regions,
1693       thus keeping current-time-step OB values; and remove the call to OBCS_APPLY
1694       which were applying future time-step OB values.
1695      This way, all explicit calculations use current-time-step OB values
1696       (simpler and more consistent).
1697      Affects results when set-up uses time-varying OBC and multi-dim advection;
1698       update output of experiment seaice_obcs.
1699    o pkg/seaice:
1700      move OPTIONS (formerly locally defined) to SEAICE_OPTIONS.h:
1701       this includes SEAICE_GROWTH_LEGACY (+ SEAICE_DO_OPEN_WATER_GROWTH &
1702         SEAICE_OCN_MELT_ACT_ON_AREA ) and SEAICE_SOLVE4TEMP_LEGACY.
1703      Default (pkg/seaice/SEAICE_OPTIONS.h) is to define SEAICE_SOLVE4TEMP_LEGACY
1704       but leave SEAICE_GROWTH_LEGACY undef ; For now, keep verification exp
1705       unchanged (SEAICE_GROWTH_LEGACY defined in */code*/SEAICE_OPTIONS.h)
1706    o pkg aim (2010/10/26):
1707      - Introduce ALLOW_INSOLATION, moving toward a more general incoming solar radiation
1708        formulation with obliquity, eccentricity, ... as run-time parameters,
1709      - Introduce diagnostics for top-of-the-atmaophere incoming solar radiation and
1710        upward shortwave radition at the surface (all-sky and clear-sky).
1711    o pkg/obcs:
1712      - writing sections with globalFiles=T does not work: switch to tiled-files
1713        when writing sections for OBCS (change pkg/rw/write_rec.F accordingly).
1714      - fix index bug (OB_Ie -> OB_Iw_) in obcs_apply_uvice.F
1715      - apply OBCS_SEAICE_COMPUTE_UVICE to both uice and vice at all obcs
1716    
1717    checkpoint62m (2010/10/21)
1718    o pkg/seaice: vectorize seaice_solve4temp.F
1719      - move iterations loops outside of i/j-loops
1720      - requires 2D arrays for TB and effConduct
1721      - add 2D iceOrNot to replace HICE_ACTUAL.GT.0, as HICE_ACTUAL is
1722        modified in this routine
1723      - a little bit of clean up, adjusting indentation, etc.
1724      - replaced a few TEN**a by exp(a*log(10.)) in new code for better
1725        performance and '**TWO' by '**2' (because TWO is a float),
1726        replaced ONE, ZERO
