4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/seaice:
8     - update comments in SEAICE_OPTIONS.h (+ similar update of lab_sea/code and
9       global_ocean.cs32x15/code versions).
10     - turn on seaice Multi-category (in data.seaice, SEAICE_multDim=7) for
11       verification experiment global_ocean.cs32x15.seaice and update results.
12    o pkg/exf:
13     - new S/R EXF_GETFIELD_START to return starting-time of a forcing field
14       (according to useExfYearlyFields).
15    o pkg/cal:
16     - move calendar setting & summary (previously in cal_readparams.F) into new
17       S/R CAL_INIT_FIXED to be called later in the initialisation process, once
18       length of the simulation is set (after SET_PARMS call); This is an attempt
19       to fix Pb when, e.g.: pkg/longstep, modifies the length of the run.
20     - For safety: keep a record of pkg/cal parameter settings status
21               to allow to STOP if one pkg/cal S/R is called too early.
22     - add a stop in all basic pkg/cal subroutines if called before setting is done.
23     - modify cal_getdate.F: stop when nothing was returned;
24       if called with myIter=-1, simply retrun modelBaseDate (1,2 = startDate_1,_2);
25       this allows to remove "cal.h" from seaice_read_parms.F & init_mnc_vars.F.
26    
27    checkpoint63l (2012/04/04)
28    o pkg/bbl:
29      - fix call to FIND_RHO_2D in bbl_calc_rho.F (case multi-tiles per proc);
30        update global_with_exf output.yearly.txt file.
31    o pkg/cal:
32      - start to clean-up cal_set.F ; fix for the case where baseTime is non-zero.
33      - remove 2 unsused and very short (1 line only) functions ;
34      - remove unsused subroutines from AD-Diff list.
35    o model/src:
36      - start to implement clean wait to stop in initialization S/R (config_check.F,
37         packages_check.F, ini_parms.F and pkg/obcs/obcs_check.F + pkg/mypackage)
38    o folowing PRINT_MESSAGE changes:
39      - remove reminder multiple print to the same file (STDOUT) when multi-threads.
40    o pkg/bbl:
41      - modification so it can work with z*
42      - replace deltaT with dTtracerLev(k) for asynchronous time stepping
43      - global_with_exf/input.yearly verification; changes output.yearly.txt
44    o eesupp/src:
45      - PRINT_MESSAGE: use OpenMP critical instruction (similar to PRINT_ERROR);
46        writing to unit 0 (if unit=errorMessageUnit) extended to the case myThid=1
47      - CHECK_THREADS: specific code if using OpenMP threading: improve checking of
48        # of threads across processors (e.g., different env OMP_NUM_THREADS setting)
49      - improve special preliminary call to EESET_PARMS (if eedata is read 2 times).
50      - when using MPI, always set usingMPI=T ; set default accordingly and stop
51        if not consistent.
52      - ALL_PROC_DIE: add a BARRIER after MPI_FINALIZE call ; skip this when thread
53        argument is zero (in case called within single-thread section).
54    o pkg/fizhi:
55        clean-up turbulence cold-start switch: decided in fizhi_init_vars.F, stored
56        in common bloc (fizhi_coms.h) and then passed as argument up to S/R TURBIO.
57    o pkg/exch2:
58      - add argument "updateCorners" to S/R exch2_get_uv_bounds (enable to
59        activate EXCH_IGNORE_CORNERS in vector EXCH S/R).
60      - switch 1rst EXCH call to IGNORE_CORNERS (instead of UPDATE_CORNERS)
61        but keep the 2nd with UPDATE_CORNERS: this prevents overwriting good data
62        with bad ones coming from a not-yet-updated halo.
63        This should fix the problem when sNx <> sNy and GCD(sNx,sNy) < 2*Olx.
64    o pkg/frazil:
65        move FrzForcT diag from frazil_diagnostics_state.F to frazil_calc_rhs.F
66        http://mitgcm.org/pipermail/mitgcm-devel/2012-March/005384.html
67    o model/src/config_check.F: add a check for OLx>sNx/OLy>sNy
68    o verification/lab_sea
69      * #undef SEAICE_EXCLUDE_FOR_EXACT_AD_TESTING
70      * #define ALLOW_SST_CONTROL & ALLOW_SST_CONTROL
71      * nTimeSteps 3 -> 4
72      * changed reference output accordingly
73    o pkg/ctrl:
74      * fix ctrl_get_gen for xx_sst, xx_sss
75    o pkg/fizhi:
76      - fix 2 calls to S/R GRD2MSC (argument igrd) in update_earth_exports.F
77        update results of exp. fizhi-cs-32x32x40 (fail with only 6 digits for cg2d)
78      - by default, use new version of S/R GETPWHERE (#define TRY_NEW_GETPWHERE);
79        fix few out-of-bounds indices in referencing vars (initialise igrd to 1);
80        clean-up fizhi_turb.F (remove unused & uninitialised qdiaglsm array).
81    o pkg/gmredi:
82      - add diagnostic of Redi (main diagnonal) vertical diffusive flux of Temp
83    o pkg/fizhi:
84      - fix few initialisation and multi-tile Pb: aqualev & gridalt now pass the
85        (old)aces open64 tuv test.
86    o pkg/icefront: fix bug and reorder loop in icefront_init_varia.F
87    o pkg/mom_vecinv:
88      - fix 1 loop range in mom_vecinv.F to be like all the other loops which
89        set/update gu,gv/Diss (fix Pb of uninitialised fVerUkp in admom_vecinv
90        with non-lin free-surf).
91    o model/src: move k-loop outside of i/j-loops when (re-)computing R_low
92      in ini/update_masks_etc.F in order to avoid -O3 optimization problems with
93      some compilers (gfortran 4.6.0 on MacOS)
94    o momentum:
95      - separate fVer?(:,:,kUp) & fVer?(:,:,kDown) in argument list of MOM_FLUXFORM
96        & MOM_VECINV subroutines (to help TAF). This fixes Pb of uninitialised
97        fVer?(kUp) in admom_fluxform with non-lin free-surf or bottom control.
98    
99    checkpoint63k (2012/03/17)
100    o model/src:
101       - selectAddFluid (ALLOW_ADDFLUID): add missing term in horizontal momentum
102         flux-form (mom_fluxform.F) and vertical momentum (calc_gw.F) equations.
103       - SOLVE_DIAGONAL: switch default to use adjoinable & vectorized version
104         (#undef SOLVE_DIAGONAL_LOWMEMORY); update output of exp. front_relax.bvp.
105    o model/src: solve_*diagonal.F
106       - replace division with multiplication by inverse (similar to original version)
107         update output of AD exp. global_ocean.90x40x15.
108       - fix pkg/gmredi/gmredi_calc_psi_bvp.F & pkg/ggl90/ggl90_calc.F
109         to enable the use of the vectorized & differentiable solve_tridiagonal.F
110       - test exp. global_ocean.90x40x15/input_ad: switch to advection scheme 20 for
111         vertical advection (to get solve_tridiagonal tested in AD mode).
112    o pkg/seaice: ECCO-CLIVAR merge:
113      1. seaice AREA relaxation
114         * CPP option: SEAICE_ALLOW_AREA_RELAXATION
115         * runtime flag: SEAICE_tauAreaObsRelax
116      2. modified global mean cost imbalance code: CPP option
117          ALLOW_SSH_GLOBMEAN_COST_CONTRIBUTION
118    o another iteration on solve_*diagonal.F
119       Make choices independent of AUTODIFF
120       Default will be the adjoinable vectorized version.
121       Alternative choices are:
122       * non-adjoinable original version with low memory footprint:
123         #define SOLVE_DIAGONAL_LOWMEMORY
124       * still adjoinable but does not vectorize (k as inner-most loop):
125         #define SOLVE_DIAGONAL_KINNER (keeping SOLVE_DIAGONAL_LOWMEMORY undef)
126    o testreport
127     - add option to use a home made wrapper around "make"
128     - remove MITGCM_IEEE env. variable (no longer active)
129    o pkg/shelfice
130     - improve computation of friction velocity for velocity dependent
131       exchange coefficients: include velocities into SHELFICEBoundaryLayer
132       block to average velocities vertically
133     - add TAF store directives for SHI_ALLOW_GAMMAFRICT
134    o Modify diagonal solvers, now three versions (upon request):
135      #ifndef SOLVE_DIAGONAL_AUTODIFF
136        1. default version (dating back a while ago)
137      #else /* def SOLVE_DIAGONAL_AUTODIFF */
138      # ifdef SOLVE_DIAGONAL_KINNER
139        2. adjoinable version with k-innermost loop (G. Forget)
140      # else
141        3. adjoinable vectorized version of 2.
142      # endif
143      #endif /* SOLVE_DIAGONAL_AUTODIFF */
144      All flags are currently set within routines, but could/should be moved to CPP-options.
145      Array bounds for 1. are as before, for 2.,3. cover the entire domain
146      (could be changed for 1. too).
147    o verification/lab_sea (fwd):
148      - update the 4 fwd lab_sea test experiment: no longer SEAICE_GROWTH_LEGACY,
149        use 7 categories (except hb87), new solve4temp params (except salt_plume),
150        constant salinity (=4) or variable salinity (salt_plume) done through
151        SItracer.
152    o pkg/seaice:
153      - rename parameters: SIsalFrac to SEAICE_saltFrac & SIsal0 to SEAICE_salt0;
154      - remove old parameters ( SEAICE_freeze, SEAICEturbFluxFormula, SEAICE_gamma_t,
155         SEAICE_gamma_t_frz, SEAICE_availHeatTaper & SEAICE_availHeatFracFrz)
156        from SEAICE_PARMS.h ; still need to fix seaice_cost_sst.F (broken when
157        SEAICE_freeze got retired) but already better than previously with
158        SEAICE_freeze=123456.7 deg.C;
159      - move setting of facOpenGrow/Melt from SEAICE_INIT_FIXED to SEAICE_READPARMS
160        (safer multi-threaded setting); always set SEAICEuseEVP;
161      - setting of ocean-ice turb. flux coeff: moved from SEAICE_CHECK to
162        SEAICE_READPARMS & SEAICE_INIT_FIXED (this fixes wrong summary report);
163        stop if multiple specifications for the same coeff; make sure default
164        SEAICE_mcPheePiston is compatible with drF(1) & deltaT.
165    o pkg/obcs:
166      - allow to switch to upwind 1rst order advection scheme for the advective
167        flux computation at the open-boundary; disabled for adjoint built.
168    o pkg/ptracers:
169      - rename PTRACERS_RESTART.h -> PTRACERS_START.h
170      - rename ptracers_fields_blocking_exchanges.F -> ptracers_fields_blocking_exch.F
171      - add parameter to decide when to start a tracer; use internal flag to
172        know which tracer to step-forward; switch this internal flag at the top
173        of forward_step.F (new S/R PTRACERS_SWITCH_ONOFF); for now, not enabled
174        for adjoint built.
175    o pkg/seaice:
176      - add SEAICE_SIZE.h anywhere in the code where SEAICE.h is included ;
177      - move MULTDIM declaration and setting from SEAICE.h to SEAICE_SIZE.h ;
178      - keep experiment offline_exf_seaice truly single category (set MULTDIM=1).
179    o pkg/ecco:
180      - fix writing of output file DiagnosCost_ClimSalt/Theta
181        and DiagnosCost_DriftSalt/Theta (if multi-tiles per proc).
182    o pkg/seaice:
183      - add missing initialisation of COR_ICE array in dynsolver.F
184      - merging SEAICE_MULTICATEGORY define and undef cases. Now the same code is
185        compiled either way, and is tested in all exps (multidim was only tested
186        in lab_sea ad before).
187      - cosmetic change to prepare for future addition of ITD. no change to results.
188        no defaults change.
189      - added run time param SEAICE_multDim (7 for SEAICE_MULTICATEGORY, 1 otherwise).
190      - by lack of adequate verification experiments, I further used custom versions
191        of global_ocean.cs32x15 to test multicat or not, with pickup or not. All
192        should be correct.
193      - avoid recomputations in ad.
194    o array initialisation in adjoint mode:
195      1) pkg/mom_common/mom_calc_ke.F:
196        add full array initialisation of KE inside mom_calc_ke.F (ALLOW_AUTODIFF_TAMC):
197        The S/R which calls MOM_CALC_KE initialises KE but in some recomputation
198        part this initialisation is gone, resulting in Floating Point Exception
199        (caught by open64 compiler with debug option).
200      2) model/src/convective_weights.F
201        set output convectCount over the full array range (instead of doing
202        an update): this fix a similar issue when called within recomputation (adjoint)
203        which could by-pass the initialisation (normally done in the caller S/R).
204    o pkg/seaice:
205      - final version of turbulent flux params, as agreed at MIT ice meet:
206           SEAICE_mcPheePiston (default is ~ 0.000875)
207           SEAICE_mcPheeTaper (default is 0.)
208           SEAICE_frazilFrac (defualt is 1.)
209           SEAICE_mcPheeStepFunc (default is false)
210      - changes results at trunction error level
211      - ifdef SEAICE_EXTERNAL_FLUXES, disallow SEAICE_waterAlbedo
212    o added pkg/frazil:
213      - see frazil_description.tex for details
214      - verification experiment is global_with_exf/input.yearly; changes output.yearly.txt
215    o pkg/shelfice/shelfice_thermodynamics.F
216      - fix exponents for velocity dependent exchange coefficients: change
217        from 2/3(=0) to 0.66666666666666667
218      - move computation of velocity dependent exchange coefficients into
219        separate loop, so that it applies to both thermodynamics
220      - move some divisions by constants out of loops
221    
222    checkpoint63j (2012/02/16)
223    o pkg/seaice:
224      - overhaul of seaice_summary.F after feb 2012 clean-up of seaice_growth.F etc.
225      - SItracer:  added run time params, and allow coupling to ocn salinity.
226    o pkg/seaice: remove (almost) all divisions by constants within loops
227      in seaice_growth.F and seaice_solve4temp.F, this changes (only) the cg2d
228      results of global_ocean.cs32x15.seaice from 16 to 11 digits (but only
229      those, caused by 1/QI -> recip_QI) -> update output.seaice.txt,
230      output_adm.seaice_dynmix.txt and also lab_sea: output_adm.evp.txt
231    o pkg/seaice :
232      - simplify McPhee tapering, and allow to use it with SEAICEturbFluxFormula
233        = 1 or 2, using newly added run time parameter SEAICE_availHeatTaper.
234      - fix d_AREAbyATM, d_AREAbyOCN, d_AREAbyICE diags I broke in r1.148.
235      - add permanent SItflux diag that corresponds to TFLUX but includes
236        ice+snow. Hence SItflux-TFLUX should match the ice+snow heat budget.
237      - allow activation/testing of a fix for suspected missing term in
238        ocn-ice heat budget (to be confirmed). To test this, you want to
239        undef SEAICE_DISABLE_HEATCONSFIX, and then set the run time param
240        SEAICEheatConsFix to .TRUE. that also allows the 'SIaaflux' diagnostic.
241      - no change in results, fwd or ad.
242    o global_ocean.cs32x15/results: 3 changes following from the pkg/seaice commit below:
243      - switch to variable freezing point.
244           Results change : cg2d -> 1 digits; ad -> 3-6-6 digits.
245      - bug fix : the sublimation term that was missing is now activated.
246           Results change : cg2d -> 2 digits; ad -> 8-6-6 digits.
247      - bug fix : flooding sign term for SIsal0.NE.0.
248           Result change : cg2d -> 8 digits; ad -> 11-12-9 digits.
249    o pkg/seaice:
250      - unified freezing point treatment : the old SEAICE_VARIABLE_FREEZING_POINT
251        is now the default, and the old default constant freezing point is recovered
252        with SEAICE_tempFrz0    = -1.96,
253             SEAICE_dTempFrz_dS = 0.,
254      - retire SEAICE_freeze (= the old way of specifycing the constant freezing point)
255      - remove ALLOW_SEAICE_FLOODING brackets; run time switch is already there.
256      - bug fix (thanks to M. Losch) : the sublimation term that was missing is now
257        activated. To reproduce old results with this bug define SEAICE_DISABLE_SUBLIM.
258      - bug fix (silly me) : flooding sign term (seaice_growth.F r 1.149line 1211)
259        was wrong for SIsal0.NE.0. Changes cs32x15 results (see above item for detail).
260      - bug fix (thanks to O. Jahn) : area loss for melting  got messed up in
261        seaice_growth r149 for legacy branch (no results change).
262      - introduce SEAICE_CAP_SUBLIM : caps sublimation heat flux in solve4temp (code
263        from I. Fenty).
264      - results did not change except for global_ocean.cs32x15, mostly due to the
265        switch to variable freezing point (see above item for detail).
266    o pkg/thsice:
267      - fix and simplify interface to salt_plume pkg ; diagnose directly amount of
268        seawater freezing in thsice_calc_thickn (not used).
269    o pkg/seaice: turbulent flux term specification via run time params.
270      - replace CPP switches with run time switches to facilitate testing
271      - retired CPPs : MCPHEE_OCEAN_ICE_HEAT_FLUX,
272                       GRADIENT_MIXED_LAYER_TURBULENCE_FACTOR
273      - added runtime parameter : SEAICEturbFluxFormula
274      - move Mcphee constants to SEAICE_PARAMS.h
275      - seaice_readparms.F : read turbulent flux term params (SEAICEturbFluxFormula;
276                 SEAICE_availHeatFrac/Frz, or SEAICE_gamma_t/_frz if apply);
277                 remove seaice_summary call (moved to seaice_init_fixed)
278      - seaice_init_fixed.F : set SEAICE_availHeatFrac/Frz depending on
279        SEAICEturbFluxFormula, and seaice_summary call (moved from seaice_readparms)
280      - seaice_summary.F : add missing report of read turbulent flux term set up
281                           and SITRACER.
282      - seaice_check.F : check range; inform and stop if retired CPPs are used
283                         (incl. SEAICE_AGE).
284      - seaice_growth.F : unified use of SEAICE_availHeatFrac/Frz, without
285             CPP switch, same computation as before for the different options.
286      - change results at the truncation level.
287    o pkg/seaice:
288      - remove un-used parameters LAD & MAX_TICE ; add new run-time parameters:
289        useMaykutSatVapPoly (default=F), postSolvTempIter (default=2) and
290        SEAICE_wetAlbTemp (default=-1e-3). Remove option SEAICE_SOLVE4TEMP_LEGACY.
291      - update verification/*/input*/data.seaice:
292        to reproduce previous results with former #defined SEAICE_SOLVE4TEMP_LEGACY
293        code, set useMaykutSatVapPoly=T & postSolvTempIter=0 ;
294        and to reproduce previous results with former non-SOLVE4TEMP_LEGACY code,
295        set SEAICE_wetAlbTemp=0 & SEAICE_snowThick=0.
296    o pkg/seaice/seaice_solve4temp.F (SOLVE4TEMP_LEGACY):
297      - remove LEGACY code for solving for tsurf (A1,A2,A3) but maintain the same
298        algorithm (same choice: useMaykutPolySatVap=T, postSolvTempIter=0);
299        difference in results only due to machine truncation.
300      - remove MAX_TICE (tsurf is always =< TMELT anyway); keep MIN_TICE if using
301        MaykutPolySatVap; keep MIN_LWDOWN.
302      - adapt SEAICE_MODIFY_GROWTH_ADJ code (untested) to non-legacy formulation.
303      - update output of verification exp. lab_sea (4 fwd: 11 cg2d digits except hb87,
304        + 3 AD: 6 digits except evp) and offline_exf_seaice.seaice (12 digits).
305    o pkg/salt_plume:
306      - isolate saltPlumeFlux array exch into a specific S/R called from
307        do_oceanic_phys.F
308      - add interface to pkg/salt_plume (filling of saltPlumeFlux) in pkg/thsice.
309    o verification:
310      - move untested set-up to MITgcm_contrib/verification_other.
311    o pkg/seaice:
312      - retire old way of SEAICE_AGE. Now replaced with ALLOW_SITRACER.
313    o pkg/seaice:
314      - seaice_solve4temp.F (keeping results unchanged):
315        * add 2 future run-time params to select which saturation vapor pressure
316          formula is used and how post-iteration fluxes are set.
317          Temporary set these 2 params according to option SOLVE4TEMP_LEGACY;
318        * New piece of code (not used) to update surf. atmos. heat flux F_ia using
319          the linearized expression to stay consistent with tsurf finding.
320      - seaice_freedrift.F avoid floating exception in sqrt(y) since y=sqrt(x*x)-x
321        can be < 0.
322    o pkg/seaice/seaice_solve4temp.F (SOLVE4TEMP_LEGACY undef):
323      - remove from F_ia (and from it's derivative dFiDTs1) the contribution of
324        conductive heat flux F_c , and add it explicitly when updating tsurf as
325        solution of: Fc = Fia + d/dT(Fia - Fc) *delta.tsurf
326        so that now F_ia has a consistent meaning through the entire routine.
327        This causes differences at truncation level: update output of fwd exp.
328        global_ocean.cs32x15.seaice.
329    o pkg/seaice:
330      - lots of editing/cleaning in seaice_solve4temp.F + better documentation
331        of arrays, sign/direction of fluxes; no effect on results.
332      - replace hard coded 273.16 (=previous value of celsius2K) by celsius2K
333        in seaice_budget_ocean.F & seaice_solve4temp.F (SOLVE4TEMP_LEGACY part);
334        note: this should have been done before changing celsius2K default.
335      - to keep results unchanged, add back old value of celsius2K in verification
336        exp. input*/data : lab_sea (AD), offline_exf_seaice (fwd+AD) & seaice_obcs
337      - replace hard coded seawater freezing temp in seaice_solve4temp.F (part
338        SOLVE4TEMP_LEGACY) of 271.20 (=previous value of celsius2K + default
339        value of SEAICE_freeze) by celsius2K+SEAICE_freeze so that seawater
340        freezing temp is consistent with value in seaice_growth.F ; this causes
341        differences at machine truncation level: update lab_sea AD output (3/4).
342    o pkg/seaice:
343      - mask (in exf_init_fixed.F) atemp,aqh,evap,precip,runoff,lwflx,areamask
344        and climsst/sss even when using seaice (to prevent calculation that might
345        use SST on land); does not affect any verification exp.
346      - apply mask to taux,tauy (in seaice_get_dynforcing.F); update output
347        of lab_sea.fd & lab_sea.hb87 and global_ocean.cs32x15.seaice_dynmix.
348    o pkg/seaice/seaice_growth.F: add mask to avoid non-zero ice thickness
349      over land (non-legacy code)
350    o vectorize salt_plume package:
351      - add extra code to salt_plume_frac and salt_plume_tendency_apply_s
352      - this code computes plumebk everywhere (also over land), thus requires
353        code to avoid divisions by zero and catch the case of kLev=Nr.
354      - efficiency of salt_plume_frac is still sub-optimal
355    o tools (genmake2):
356      - fix makefile NAME specification (option: -makefile NAME) by adding
357        "-f $MAKEFILE" in few places where it was missing including makedepend
358        command (contribution from Paul).
359    
360    checkpoint63i (2012/01/24)
361    o model/src:
362      - add factorized versions of some EOS code to find_rho.F,
363        define USE_FACTORIZED_EOS to turn it on (default for TARGET_NEC_SX)
364    o model/src:
365      - add celsius2K to namelist PARM01; remove unused recip_rhoNil from PARAMS.h;
366      - change default celsius2K from 273.16 to 273.15
367      - to keep results unchanged, add back old value of celsius2K in verification
368        exp. input*/data : aim.5l_cs, 1D_ocean_ice_column, lab_sea (fwd),
369         global_ocean.cs32x15(seaice) & cpl_aim+ocn(input_atm).
370    o model/src: add a little initialisation trick to find_rho.F and find_alpha.F
371      to make TAF generate vectorizable code
372    o pkg/seaice/seaice_evp.F: add code (copied from CICE) that avoids underflows.
373       Turn on by defining SEAICE_EVP_ELIMINATE_UNDERFLOWS. Most compilers
374       have flags that do this more efficiently.
375    o pkg/diagnostics/diagstats_calc.F
376      - for TARGET_NEC_SX fix the treatment of the scaling factor tmpFac=scaleFact
377    o pkg/obcs (with exch2):
378      - derive OB indices in overlap region from OB-InsideMask (in obcs_init_fixed.F)
379        and remove code (in obcs_readparms.F) which was based on EXCH of indices
380        (through buffer) and did not account for exch2 (e.g., CS-grid) topology.
381    o pkg/exf and seaice exp:
382      - change offline_exf_seaice.seaicetd test exp. to use default DIFF1 value (=0)
383        so that switching off area & heff advection flags does not affect results.
384      - change default EXF_LWDOWN_WITH_EMISSIVITY to #define in EXF_OPTIONS.h
385      - keep exp. seaice_obcs & 1D_ocean_ice_column(ad) unchanged (using #undef
386        EXF_LWDOWN_WITH_EMISSIVITY) and, using pkg/exf default emissivities, update
387        results of verification experiments: 1D_ocean_ice_column(fwd),
388        global_ocean.cs32x15.seaice(fwd+ad) & seaice_dynmix(ad), lab_sea (all 8)
389        and offline_exf_seaice (all 4).
390    o pkg/seaice:
391      - remove array YNEG, RIVER, TMIX (replaced by local var) from common block;
392        remove also areaNm1 & hEffNm1 when SEAICE_GROWTH_LEGACY is undef.
393      - fix bug: areaNm1 & hEffNm1 are needed in seaice_growth (SEAICE_GROWTH_LEGACY)
394        but were not filled when resp. SEAICEadvArea=F & SEAICEadvHeff=F and
395        not multi-dim advection;
396      - fix seaice_growth.F to compile with both SEAICE_GROWTH_LEGACY and
397        SHORTWAVE_HEATING #undef.
398    o optim: make Makefile more robust (?)
399    o pkg/obcs:
400      * fix treatment of obcs_read_pickup for TAF
401    o pkg/shelfice:
402      * add missing initialisation of num_shifwflx
403      * new adjoint verification exp. for isomip
404      * change Prandtl and Schmidt numbers from generic formulations
405        (in terms of model diffus. and visc.) to separate runtime
406        parameters, with Holland and Jenkins (1999) default values.
407    o pkg/exf (interpolation):
408      - extended input field (2 rows) near the N & S poles:
409        * fill in with the symetric value (when even Nb of data in longitude)
410        * add average value at the poles only for scalar quantities ; for vector
411          component interpolation, skip the averaging and keep duplicated values,
412          unless the 2 components have same location (uvInterp=T) in which case
413          interpolate the 2 components together using S/R EXF_INTERP_UV.
414      - new S/R EXF_INTERP_UV to interpolate the 2 components of a vector field
415        together: this allows to account properly for local orientation when
416        averaging at N & S pole.
417      - add CPP option EXF_USE_OLD_INTERP_POLE to recover old results regarding
418        exf-interpolation near N & S poles. Undef by default.
419      - add debug check/print on 1rst iter if debugLevel >=2.
420    o pkg/exf:
421      - change masking flags definition (no longer "parameter"), put them in
422        common block and set them in S/R EXF_INIT_FIXED.
423      - change recognized masking flag from s,u,v to c,w,s since the mask
424        to use (maskC,W,S) depends on position on model grid and has little to
425        do with scalar/vector difference; fix masking if using P-coordinates.
426      - fix masking of wind-stress (was wrong if interpolated or read on A-grid)
427        and update results of exp. global_with_exf (x2).
428      - fix setting of zenith-angle table when SHORTWAVE_HEATING is undef.
429    o pkg/obcs
430      - S/R obcs_calc_stevens: fix a small bug (gammat -> gammas where appropriate)
431    o pkg/exf (interpolation):
432      - assume periodicity in X only if input field cover full longitude range.
433      - improve search for lat. index (supposed to be faster, in ~log2(ny) steps,
434        and should vectorise).
435      - fix input lat of the 2 added row (in case we provide N.pole data).
436    
437    checkpoint63h (2011/12/30)
438    o pkg/seaice:
439      - change declaration of UVM from _RL to _RS in order to get B-grid
440        uIce,vIce monitor when _RS = real*4
441    o pkg/offline:
442      - new S/R OFFLINE_RESET_PARMS for resetting main-model params (switch off flags);
443      - compute vertical velocity if not read from file (switch on exactConserv
444        & staggerTimeStep);
445      - fix output of ptracer monitor iter & time for default PTRACERS_monitorFreq.
446    o verification:
447      - update grid-files (in tutorial_held_suarez_cs/input and fizhi-cs-32x32x40/input)
448        with grid-angle generated using "utils/matlab/cs_grid/cubeCalcAngle.m":
449        fix Pb in yG definition @ 2 missing corners (previously yG was averaged);
450      - update output of exp. global_ocean.cs32x15.viscA4 after changing
451        grid-file angles (used here for coriolis-3d);
452      - remove (or gzip) few files not needed to run fizhi-cs experiments.
453    o pkg/exf (vector interpolation):
454      - rotate vector component toward local grid-axis orientation using grid-angles
455        (stored in GRID.h) instead of locally computed rotation angle; keep old code
456        available with exf option EXF_USE_OLD_VEC_ROTATION (undef by default).
457    o pkg/seaice:
458      - allow to compile with exf options ALLOW_ATM_TEMP or ALLOW_DOWNWARD_RADIATION
459        undefined. Fix and remove the stop when ALLOW_RUNOFF is undefined.
460    o pkg/PKG_OPTIONS.h files:
461      - move #include "CPP_OPTIONS.h" just after #include "PACKAGES_CONFIG.h",
462        outside of the #ifdef ALLOW_THISPKG / #endif block.
463      - update verification/*/code/PKG_OPTIONS.h files.
464    o add a verification experiment (offline_exf_seaice/input.seaice) that test
465      the B-grid LSOR solver
466    o pkg/seaice: sort out emissivity and long wave radiation step 2:
467      - add emissivity for snow and ice as new run-time parameters
468        (unfortunately) that default to the corresponding exf values; this
469        changes results in most verification experiments so that for backward
470        compatibility these parameter have to be set explicitly to inconsistent
471        values (ugly);
472      - the exf-flag EXF_LWDOWN_WITH_EMISSIVITY then gets rid off the hard-wired
473        emissivities of 0.97 associated with lwdownloc in S/R seaice_solve4temp
474        until we agree how to handle this bug properly
475    o pkg/exf (interpolation):
476      - add a set of run-time param ({inputfield}_interpMethod), one for
477        each interpolated input field, to select the interpolation method
478        with a value of zero switching off the interpolation;
479      - print interpolation parameters to standard output;
480      - refine exf_check.F accordingly ; stop if USE_NO_INTERP_RUNOFF is defined
481        (to use instead runoff_interpMethod=0 in data.exf).
482      - simplify default setting of interpolation parameters (for all fields,
483        set position to match model grid cell-center position, leading to trivial
484        interpolation in case of regular Lat-Lon grid) and fix for the case of
485        non-uniform delY.
486    o pkg/exf/exf_radiation.F: add the factor ocean_emissivity to lwdown, for
487       within #ifdef EXF_LWDOWN_WITH_EMISSIVITY/#endif. Unless ocean_emissivity=1.
488       this factor is absolutely required, because the lw exitance (= out-going
489       long wave radiation) is emissivity*stefanBoltzmann*T^4 + rho*lwdown,
490       where the reflectivity rho = 1-emissivity for conservation reasons. Once
491       this is established, we can remove the CPP-Flag (if we want to).
492    o pkg/seaice:
493      - qualify a stop statement in S/R seaice_check: EXF_READ_EVAP and
494        ALLOW_BULKFORMULAE are only required if SEAICE_EXTERNAL_FLUXES is defined
495      - sort out emissivity and long wave radiation, step 1: make SEAICE_emissivity
496        what the name implies (and not emissivity*BoltzmannConstant), this means
497        the old default value of 5.5e-8 now means
498        5.5e-8/5.670e-8 = 0.97001763668430343479 as ocean_emissivity in
499        S/R exf_readparms
500      - FV-discretization of the B-grid LSOR solver, turn on with
501        SEAICE_LSRBNEW. This new solver also involves a slight re-organization
502        of the calling routine dynsolver, so that B and C-grid code look a
503        little more alike.
504      - fix index bugs in ostres.F (B-grid code)
505    o pkg/seaice/seaice_ocean_budget.F: change (unused) code to make it look better
506    o pkg/seaice/seaice_readparms.F: make ocean_emissivity*stefanBoltzmann the
507      default for SEAICE_emissivity, if useEXF; requires setting a wrong
508      parameter value in global_ocean.cs32x15/input.seaice/data.seaice for
509      backward compatiblity
510    o model/src: use sigmaR in calc_ivdc
511    
512    checkpoint63g (2011/12/16)
513    o pkg/seaice/seaice_growth.F:
514      fix heat conservation of the coupled ocean-seaice system.
515      when SEAICE_HEAT_CONSERV_FIX is defined, the mismatch of
516      solid vs liquid water treatment is resolved via QNET.
517    o pkg/seaice/seaice_growth.F:
518      add missing term for sublimation in saltFlux, which was breaking conservation.
519    o pkg/seaice/seaice_model.F:
520      Remove this patholigical case treatment in evolution branch,
521      where it is un-necessary and breaks conservation.
522      Update global_ocean.cs32x15/results accordingly for
523      output.seaice.txt output_adm.seaice.txt and output_adm.seaice_dynmix.txt
524    o model/src:
525      useRealFreshWaterFlux: remove masking of EmPmP (using maskInC) in
526      external_forcing_surf.F and apply mask directly in S/R SOLVE_FOR_PRESSURE.
527    o pkg/obcs:
528      modify Stevens boundary conditions so that S/R obcs_calc_stevens computes
529      tendency for temperature and salinity that is then applied to update
530      theta and salt in S/R obcs_apply_ts; this requires proper masking of all
531      horizontal advection and diffusion contributions on the boundary (in
532      S/Rs gad_advection, gad_calc_rhs, gmredi_rtransport, gmredi_calc_diff), and
533      removing the mask in S/R timestep_tracer. The advantage of this approach is
534      that the updated tracer values include contributions from the surface
535      forcing and vertical diffusion.
536      This modification changes exp4.stevens because of vertical diffusion.
537    o model/src:
538      change non-curvilinear grid setting to also work with exch2 + blank tiles:
539      - move delX,delY to new header file (SET_GRID.h) and adjust length to 1rst
540        face dimensions.
541      - new S/R INI_LOCAL_GRID to define model tile-local grid (using same units
542        as delX,delY) and called from S/R INI_CARTESIAN_GRID, INI_CYLINDER_GRID
543        and INI_SPHERICAL_POLAR_GRID.
544      change test-experiment global_ocean.90x40x15:
545      - split the domain in many more tiles (9x4 tiles of 10x10 each);
546      - switch to exch2 and remove 1 blank-tile (but only for MPI test).
547      - update results of both test (std & dwnslp).
548    o pkg/diagnostics/diagstat_calc.F: fix problem with non-initialised halos in
549       tmp-fields for TARGET_NEC_SX at the cost of extra loops and less vectorisation
550    o model/src:
551      - take sigma-coords related code out of update_etah.F into new S/R UPDATE_ETAWS
552        and fix initialisation when using sigma-coords.
553    o model/src:
554     - improve Gael's changes from Jan 14, 2011 "addition of an 'update' of hfacc etc.
555       to their current value at the beginning of forward_step.F": add a new run-time
556       switch "doResetHFactors" (default=false) and use it to do (or not) the resetting.
557     - set doResetHFactors=T in the following test exp:
558        global_ocean.90x40x15/input (rStar) & input.dwnslp (linFS),
559        global_ocean.cs32x15/input.seaice (rStar), hs94.cs-32x32x5/input.impIGW (linFS)
560        and tutorial_global_oce_in_p (nonLinFS in p)
561    o pkg/ecco
562      - added IES cost term
563    o verification/advect_xz
564      - scale down the depth by 1/100 (from 200 km to just 2.km)
565      - add secondary test using divergent flow, r-star and implicit vertical advection.
566      - add note (check_conserve_TS.txt) and matlab script to check global
567        conservation of T & S with NonLin-FreeSurf and Adams-Bashforth.
568    o pkg/rbcs:
569      - add missing relaxUFile & relaxVFile in namelist (in rbcs_readparms.F).
570    o pkg/obcs (Stevens BCs):
571      - fix various problems in the phase speed computations of the Stevens
572        boundary conditions:
573        - sign error for western and southern boundaries,
574        - time tendencies were underestimated by factor of dTracerLev and some just
575          zero (for multidim advection schemes) -> now estimate time tendencies
576          from difference between previous (n) time level and the one before (n-1);
577          this requires storing a field per tracer per boundary, also in the pickup
578          files.
579        - replace deltaTmom in cflMer/Zon computation with dTracerLev
580        - set default phase velocity to cflMer/Zon
581      - update verification experiment exp4.stevens
582    o pkg/generic_advdiff (implicit_r):
583      - fix implicit vertical advection conservation with AB and/or NonLin-FreeSurf
584        (remove Tr*d/dz(w) in gad_implicit_r.F and add it in gad_calc_rhs.F);
585      - fix implicit vertical diffusion or advection with NonLin FreeSurf
586        (was using current recip_hFacC instead of future recip_hFacC): set future
587        recip_hFac in thermodynamics.F and pass & use it in all vertical implicit
588        solver S/R ;
589      - fill diagnostics of vertical advective fluxes (computed from tendency)
590        when using implicit vert. advection;
591      - update output of exp that uses NonLin-FreeSurf & implicit vertical diffusion:
592         global_ocean.90x40x15 (fwd+AD), global_ocean.cs32x15 (4 fwd +4 AD),
593         tutorial_global_oce_in_p (fwd), tutorial_tracer_adjsens (AD)
594         and cpl_aim+ocn (used in ocean); to be fixed: bottom_ctrl_5x5.
595    o pkg/diagnostics:
596      - add diags for T & S tendency which goes through Adams-Bashforth.
597    
598    checkpoint63f (2011/11/30)
599    o pkg/obcs/obcs_calc_stevens.F:
600      - join some loops to reduce number of if-statements
601      - fix a bug in code for northern and southern boundaries.
602    o pkg/seaice/seaice_init_varia.F
603      - undo resetting UVM=0 that has slipped in unnoticed in r1.49 and
604        caused zero ice-velocities for the B-grid code
605    o pkg/seaice/seaice_init_fixed.F
606      - fix a bug in the initialisation of the second metric terms
607        k2AtC and k2AtZ: k2AtC was set to the value of k2AtZ and k2AtZ was 0.
608      - this affects all seaice configurations with useCurviLinearGrid = .true.
609        and SEAICEuseDynamics = .true. (default) and SEAICEuseMetricTerms
610        = .true. (default)
611      - the only verification experiment affected is global_ocean.cs32x15:
612        icedyn, seaice, and seaice_dynmix (AD)
613    o pkg/thsice/thsice_diagnostics_state.F
614      - only for TARGET_NEC_SX: initialise all of tmpFld, so that overlap does
615        not contain garbage that can lead to surprises in diagstats_calc.F
616    o model/src:
617      - move bi,bj loops inside INTEGR_CONTINUITY ;
618      - call INTEGR_CONTINUITY directly from forward_step.F
619        (previously called from momentum_correction_step.F)
620      - call UPDATE_ETAH from integr_continuity.F and update initialise_varia.F,
621        forward_step.F and pkg/ecco/the_main_loop.F
622    o model/src/do_oceanic_phys.F:
623      - reset addMass to zero only if useICEFRONT ;
624      - separated k-loop for rhoInSitu calculation ;
625      - add 2 diagnostics for wVel*delta^k(Rho) at constant pressure (= WdRHO_P)
626        and at constant T,S (= WdRHOdP);
627      NOTE: change diagnostics WRHOMASS : this is now simply the Vertical transport
628        of In-Situ Density (Anomaly) (=wVel*rho^bar-k) (previously was Vertical
629        transport of locally-referenced potential density);
630        to recover old diag: (WRHOMASS)_old = (WRHOMASS)_new -1/2 * (WdRHOdP)
631    o gluemnc:
632      - replace ncrcat with ncks when adding variables to *.glob.nc
633      - change the way variables without record dimensions are handled so that
634        files that have variables with and without record variables can be glued:
635        add a record dimension with a new unique name to be able to differentiate
636        between variable with and without a-prior record dimensions. Remove
637        this record dimension before adding the variable to the *.glob.nc file.
638        This procedure automatically works also for grid.*.nc files that do not
639        have any record dimension.
640    o verification/cpl_aim+ocn:
641      - generate new reference output on baudelaire (gfortran, mpich2) (previously
642        from old aces-grid cluster, ao + ifort) and update 'run_cpl_test' script.
643    o pkg/obcs/obcs_calc_stevens.F:
644      - add code for northern and southern boundaries.
645      - reorder some loops to save some operations and so that drFBar can be scalar
646    o model/src:
647      - re-arrange extrapolation calculation in Adams-Bashforth S/R (affects machine
648        truncation) and add diagnostics for Adams-Bashforth tendency increment.
649      - update test-exp. AD output:
650        1D_ocean_ice_column, bottom_ctrl_5x5, lab_sea.noseaicedyn, obcs_ctrl;
651      and FWD output: exp4 (x3), fizhi-cs-32x32x40, fizhi-cs-aqualev20,
652        front_relax (x3), global_ocean.90x40x15 (x2), global_ocean.cs32x15 (x5),
653        global_ocean_ebm, ideal_2D_oce, internal_wave, isomip (x3), lab_sea (x4),
654        matrix_example, MLAdjust (x5), natl_box (x2), tutorial_advection_in_gyre,
655        tutorial_global_oce_in_p, tutorial_global_oce_latlon and
656        tutorial_plume_on_slope.
657    o pkg/diagnostics/diagstats_calc.F: add special code for TARGET_NEC_SX
658      that vectorises. This code uses 3 extra 2D fields, F90 array assignments
659      and F90 intrinsic routines SUM, MINVAL, MAXVAL, but since TARGET_NEC_SX
660      does not even come with an F77 compiler anymore, this should not be
661      a limitation
662    
663    checkpoint63e (2011/11/06)
664    o pkg/seaice adjoint of LSR:
665      - substantially rework STORE dirs.
666      - add new flag SEAICE_LSR_ADJOINT_ITER and parameter SOLV_MAX_FIXED
667        this flag will do SOLV_MAX_ITERS but only store SOLV_MAX_FIXED fields
668        and only perform SOLV_MAX_FIXED adjoint iters.
669        If flag SEAICE_LSR_ADJOINT_ITER is undef-ined, the store in the iteration
670        always goes to same record, meaning that the last forward field will be
671        the one used in the adjoint - an approximation.
672      - now produces non-zero LSR-related gradients, and acceptable gradients for
673        An's zonal (x-z) test case (to be checked in)
674      - lab_sea: produces acceptable gradients for lab_sea with forward/backward LSR
675        (but these are screwed up by the thermodynamics in the first place);
676        reduce from 4 to 3 timesteps to avoid t.d. issue as temporary solution;
677        output_adm.txt also reflects changes to seaice_lsr
678      - global_ocean.cs32x15:
679        * the "default" input_ad.seaice has been re-defined to always exclude dynamics
680          (output_adm.seaice.txt was updated)
681        * new input_ad.seaice_dynmix tests a forward LSR / backward free-drift
682          (output_adm.seaice_dynmix.txt)
683    o test-exp. exp4+stevens:
684      - switch off pTracers and nonHydrostatic (restart problems with NH); update output
685    o pkg/seaice (lsr solver):
686      - put coriolis term into FORCEX,Y (as in seaice_evp.F; previously in rhsU,V only);
687        update output (change truncation) of FWD test exp lab_sea & global_ocean.cs32x15
688      - fix SEAICEuseFREEDRIFT for new OBCS version (ndef OBCS_UVICE_OLD)
689      - new parameter "LSR_mixIniGuess" allows (if=2,4) to mix free-drift solution
690        into initial guess for linearised solver; use weight ~ (1/err)^2,4.
691      - compute (with new S/R) and print initial (+ free-driff sol. if available)
692        and final residual of linearised system.
693    o pkg/pp81: add diagnostics for vertical eddy viscosity and diffusivity
694      (requires new subroutines pp81_init_fixed.F/pp81_diagnostics_init.F)
695    o pkg/obcs: Stevens BCs (still only for east and west)
696      - fix Stevens BCs by using intermediate velocities of previous
697        time step as "baroclinic" contribution rather velocity of one grid cell
698        inside the boundaries; more consistent but makes the entire treatment
699        more complicated, requires new pickup files and two new S/Rs:
700        obcs_copy_uv_n and obcs_save_uv_n
701        keep old version with flag OBCS_STEVENS_USE_INTERIOR_VELOCITY
702        (undefined by default)
703      - silently move computation of some grid factors into separate loops to
704        save some recomputations
705      - add a hack for non-linear free surface
706      - add a verification experiment to exp4 that tests this code
707    o make gluemnc/xplodemnc work with (moron) non-GNU shell tools
708    
709    checkpoint63d (2011/10/25)
710    o pkg/obcs + seaice-dynamics:
711      - new implementation calls OBCS_APPLY_UVICE (in seaice_dynsolver.F) before
712        solving for uIce,vIce and prevent SEAICE_LSR or SEAICE_EVP to modify OB
713        values (consistent with an implicit method).
714      - add option OBCS_UVICE_OLD (in OBCS_OPTIONS.h, defined by default) to
715        return to older implementation (same results as before); note that none of
716        the "experimental" OBCS_SEAICE options are implemented in the new version.
717      - switch test exp. seaice_obcs to use new version (update output).
718    o pkg/seaice:
719      - add few stop (B-grid & CS-exch, B-grid & obcs, AUTODIFF & SEAICE_maskRHS)
720      - add parenthesis in Water-Ice drag calculations (evp & lsr);
721      - in seaice_lsr.F, simplify and fix AA3 setting in case sNx or sNy=1;
722        and fix case SEAICE_waterDrag=0 (but unstable if no or little seaice)
723      - update output of test exp lab_sea that uses evp or lsr (fwd+ad)
724        and global_ocean.cs32x15 (icedyn & seaice fwd+ad).
725    o pkg/layers:
726      - Include potential density as new coordinate (Thanks to David Munday)
727    o pkg/dic:
728      - Remove subroutine CALC_PCO2_APPROX_CO3 from carbon_chem.F and add
729        carbonate computation/output to CALC_PCO2_APPROX
730    o pkg/generic_advdiff
731      - make TAF generate code that vectorizes:
732        gad_dst3fl_adv_*.F, gad_u3c4_impl_r.F
733    o model/src:
734      - improve vectorization also for adjoint code of
735        solve_tridiagonal and solve_pentadiagonal. As this requires up to
736        5 new 3D-fields, this code is only turned on for the combination of
737        ALLOW_AUTODIFF_TAMC and TARGET_NEC_SX. Also remove error message
738        for singular matrix check (only for TARGET_NEC_SX).
739      - remove hard-wiring of CPP-flag ALLOW_SOLVERS_KLOOPINSIDE to
740        ALLOW_AUTODIFF. This flag now needs to be set outside of
741        solve_tri/pentadiagonal.F
742    o pkg/exf:
743      - fix previous modif in exf_readparms.F (revision 1.66: treatment of
744        optional namelist EXF_NML_OBCS).
745      - add many debug-print (to trace down where pkg/cal error msg comes from)
746    o pkg/mom_vecinv/mom_vi_hdissip.F
747      - rearrange loops so that vectorization is improved and in particular
748        the adjoint routine vectorizes. The code is a little longer now, but I
749        think easier to read.
750        Note: CPP-flag MOM_VI_ORIGINAL_VISCA4 is not tested.
751    o pkg/seaice:
752      - allow to specify initial seaice velocity from files (uIceFile,vIceFile)
753    o pkg/exch2:
754      - alternative code (without tile x tile matrix) for cumulated (global) sum;
755        used as default; keep using matrix version in adjustment.cs-32x32x1.
756    o tools/build_options:
757      - after merging some MPI and/or multi-threads specific optfiles so that
758        the modified default optfile support both built (using genmake2 -mpi
759        for the MPI built, using genmake2 -omp for OpenMP built),
760        move now obsolete optfiles to tools/build_options/unsupported/
761       (add copy of email sent to support list in doc/optfiles_changes.txt)
762    
763    checkpoint63c (2011/09/28)
764    o pkg/ebm:
765      - fix ebm_zonalmean.F for several procs in Ydir (nPy > 1); update output of
766        test exp. global_ocean_ebm (affects machine truncation, 12 digits for cg2d)
767    o pkg/seaice (SItracer pickup)
768    * Simple code for pickup of SItracer fields (#define ALLOW_SITRACER)
769      To be done:
770      - thorough testing of missing fields in S/R seaice_read_pickup
771      - thorough matching between generic tracers and specific fields used
772        (e.g. volume-weighted age, area-weighted age, salinity, ...)
773    o pkg/grdchk:
774      - all procs calculate and print finite-difference gradient (for testreport)
775      - change description output used by testreport;
776      - AD testing: also compare and report Finite-difference gradient;
777        => update all output_adm*.txt
778    o test exp. global_ocean_ebm:
779      - switch back useRealFreshWaterFlux (no problem anymore with run-off);
780        and turn on exactConserve; update (fwd) output.
781    o pkg/seaice (LSR):
782      - print to STDOUT number of solver iterations at SEAICE_monFreq interval.
783      - modify solver to deal cleanly with u/v switch at face edges (CS-grid):
784        * identical results with non-CS topology (but save up to half of EXCH calls)
785        * no much changes in cs-32 verification tests since no ice at face edges
786         (differences due to convergence criteria, since nb of iterations changed)
787        * expect some differences on lat-lon-cap grid.
788        update FWD results of global_ocean.cs32x15 test exp. (icedyn & seaice)
789    o pkg/exch2:
790      - add new CPP option to disable Cumul-Sum matrix (to save storage when using
791        many tiles); until alternative coding is added, just add a stop.
792    o pkg/kpp:
793      - move ptracer/salt correction to KPP diffusivity from calc_3d_diffusivity.F
794        to S/R KPP_CALC_DIFF_PTR (+ add tracer-index to argument list).
795    o optfiles:
796      - merged few MPI specific (*+mpi*) and multi-threads specific (*+mth) optfiles
797        into corresponding standard one, which now support different build:
798        (when using "genmake2 -mpi" for MPI built, "genmake2 -omp" for OpenMP built)
799      - add "darwin_amd64_gfortran" optfile (initially from Constantinos, tested by Gael)
800    o pkg/obcs (seaice):
801      - add missing EXCH for uIce,vIce after applying OBCS;
802      - remove S/R EXF_SWAPFFIELDS_X/Y , disable S/R EXF_SET_OBCS_X/Y by adding
803        argument = number of levels to S/R EXF_SWAPFFIELDS_XZ/YZ and S/R
804        EXF_SET_OBCS_XZ/YZ ; update obcs_exf_load.F;
805      - fix EXF_SET_OBCS_XZ/YZ for multi-threaded (assuming loaded arrays are shared)
806      - verification exp. seaice_obcs: split domain in 2 tiles ; add SIZE.h_mpi
807        and eedata.mth for MPI and mutlti-threaded testing.
808    o pkg/flt:
809      - make FLT EXCH working with multi-threads (and MPI + multi-threads);
810      - use buffer for floats IO (trajectories & profiles); size set in FLT_SIZE.h;
811      - fix pickup and trajectories + profiles output with multi-threads;
812      - add parameter to select group of fields to write along trajectory and
813        profile (default unchanged);
814      - only call PORT_RAND* function when flt_noise <> 0;
815      - add multi-threaded test for verification exp. flt_example.
816    o eesupp/src:
817      - fix S/R ALL_PROC_DIE for MPI+multi-threads.
818      - USE_OMP_THREADING: check that number of threads (from eedata) matches
819        actual number (from env.var. setting).
820    o pkg/ebm:
821      - fix multi-threading in ebm_area_t.F ; clean-up EBM.h header file.
822      - add multi-threaded test for verification exp. global_ocean_ebm
823    
824    checkpoint63b (2011/08/29)
825    o pkg/ebm:
826      - fix sign of runoff;
827      - update directly forcing fields (Qnet,EmPmR) to use standard
828        external_forcing_surf.F (remove ebm_forcing_surf.F);
829      - avoid loading forcing fields a 2nd time (1rst time from ini_forcing.F);
830      - set either tauThetaClimRelax (in data) or tauThetaZonRelax (in data.ebm)
831        and apply relaxation towards corresponding SST field (2-D map or ZonAver).
832      - update global_ocean_ebm parameters file data and update output (fwd+ad).
833    o verification/matrix_example:
834      - split domain in 8 tiles (2x4); add SIZE.h_mpi and eedata.mth for
835        MPI and mutlti-threaded testing.
836    o pkg/matrix:
837      - change name of S/R MATRIX_INIT to S/R MATRIX_INIT_VARIA ;
838      - fix for multi-tiles (add bi,bj indices to exp/impMatrixCounter);
839      - fix for multi-threaded (remove DATA statement);
840      - use standard DIFFERENT_MULTIPLE function;
841      - add MATRIX_OPTIONS.h
842    o verification/matrix_example:
843       To allow to split the domain in several tiles, change the domain size
844        from 31x31 to 32x32 by adding 1 row (on Southern side) + 1 column (on
845        Western side) of land points.
846    o (*_)write_pickup:
847      - fix few bugs in mypackage_read/write_pickup.F
848      - in MDS_WR_METAFILES calls, replace "myTime" by a local copy into
849        array of length 1 (was caught by compiler syntax-check).
850    o pkg/diagnostics (velocity potential solver):
851      - fix initialisation of main diagonal matrix (for overlap values)
852    o tools/build_options:
853      - towards single optfile for MPI and non-MPI built: merge few +mpi optfile
854        into previously non MPI one (linux_am64 pgf77,open64,pathf90,ifort11)
855      - linux_amd64_gfortran: merge +mpi_generic version into standard optfile:
856        * move IEEE flags to DEVEL section; take IEEE flags from +mpi_generic ;
857        * FAST case: for now, keep -O3 with ini_masks_etc.F in NOOPTFILES list;
858        and use "-devel" testreport option for standard testing on baudelaire.
859    o pkg/grdchk:
860      - Assume that all gradient-check position are within the same tile
861        corresponding to global indices (iGloTile,jGloTile) and that
862        positions (i,j indices or nbeg) are local to this tile;
863      - set tile local-indices and proc. number according to tile global-indices;
864      - remove grdchkwhichproc from namelist (retired param);
865      - send adjoint gradient to all procs so that all procs print it to STDOUT;
866      - switch on MPI test for global_ocean.90x40x15 AD test experiment.
867    o adding package bbl (Bottom Boundary Layer)
868      description in MITgcm/pkg/bbl/bbl_description.tex
869      example/test experiment in MITgcm_contrib/bbl
870    o adjoint verifications
871      - changed 5 experiments to multi-tiles
872        * global_ocean.90x40x15
873        * obcs_ctrl
874        * offline_exf_seaice
875        * tutorial_dic_adjoffline
876        * tutorial_tracer_adjsens
877        changed reference output for those that crossed tile boundaries
878        (changed choices of gradient check positions)
879      - with same tiling, switch on MPI test for the last 4 (add SIZE.h_mpi)
880      - temporary bug fix in grdchk_loc.F for obcs
881    o genmake2 & testreport
882      - add target "obj" (just for OBJFILES files) to Makefile;
883      - add option to specify FEXTRAFLAGS on command line.
884    o pkg/mypackage:
885      - remove bi,bj arguments from argument list of S/R MYPACKAGE_CALC_RHS
886    
887    checkpoint63a (2011/08/02)
888    o pkg/diagnostics (velocity potential):
889      - fix velocity-potential calculation when using OBCS: balance net inflow
890        at each level (new S/R OBCS_DIAG_BALANCE).
891      - fix some of the problems with OBCS in stream-function calculation.
892    o pkg/exf/exf_readparms.F
893      - make treatment of optional namelists (EXF_NML_04, EXF_NML_SGRUNOFF,
894        EXF_NML_OBCS) more consistent, so that you need not have these lists
895        in data.exf when they are not used.
896    o optim/optim_readdata.F:
897      - add some output about obcs variables that might help debugging
898      - add a check about nvarlength
899    o pkg/ctrl: once again, fix computation of endrec in s/r ctrl_init_rec
900    o pkg/diagnostics (velocity potential):
901      - fix mask for OBCS (still problems in stream-function with OBCS);
902      - add specific parameter (default = main code CG2D params) for solver;
903      - in case of poor convergence, use solution corresponding to lowest residual.
904    o pkg/seaice/seaice_growth.F: small changes that permit vectorizable
905      adjoint code. In general statements like tmpscal=fld(i,j) are problematic
906      and should be avoided where possible.
907    o model/src (rStar):
908      - include r* effect on reference-state (PhiRef) in totPhiHyd
909        (so that it's really the potential anomaly at the cell center);
910        affect solution only if z* with full pressure in EOS.
911      - test-exp global_ocean.90x40x15: reduce viscA4 (was not stable) and
912        update output (because of z* in totPhiHyd and viscA4 changes);
913      - keep the previous diagnostics as "PHIHYDcR" (closer to potential anomaly
914        @ constant r) until interpolation at constant r is implemented.
915    o pkg/diagnostics
916      - fix RCENTER diagnostics in case cell center is not at interface middle
917    o add code for TEOS-10 (www.teos-10.org, McDougall et al. 2011). Use
918      this eos with eosType = 'TEOS10', in data (PARM01). This eos implies
919      that THETA and SALT are "conservative temperature" and "absolute
920      salinity"
921    o pkg/ctrl
922      - fix computation of endrec in s/r ctrl_init_rec
923      - ctrl_pack/unpack_*: remove unused variables and some obsolete code
924    o pkg/seaice/seaice_growth.F
925      - fix recomputation with FENTY_AREA_EXPANSION_CONTRACTION code,
926        remove then obsolete STORE directives
927      - fix STORE directives for tice and tices, so that only the
928        appropriate part of the fields are stored (and not the entire
929        field); update global_ocean.cs32x15.seaice AD output.
930      - cosmetic changes: adjust CPP flags and indentation for better
931        legibilty
932    o pkg/autodiff: add mnc-output of adBottomDragFld (code contributed by
933      Chris Wilson)
934    o pkg/gmredi:
935       Add Sub-Meso Eddies parameterisation from Baylor (for now, disabled with TAF),
936       and test it in verification exp. "front_relax.bvp" (update output.bvp.txt)
937    
938    checkpoint63  (2011/07/11)
939    o pkg/exch2:
940     - rename+move: nTiles in W2_EXCH2_PARAMS.h --> exch2_nTiles in W2_EXCH2_TOPOLOGY.h
941     - exch2 version of Cumul-Sum routine: S/R W2_SET_MAP_CUMSUM set up the
942       (2*nTiles)x(nTiles) Cumul-Sum matrix and Master Proc collects all tiles X,Y
943       increments, calculates Cumul-Sum @ tile origin and sends results to each tile.
944    o pkg/diagnostics:
945     - deal with pairs of post-processed diags which are computed together; in
946       particular, re-order list of diags within 1 file to save 2nd computation.
947     - add S/R to compute velocity stream-function (called after velocity-potential
948       calculation) from divergence free transport -> new diagnostics "PsiVEL".
949     - add parameter to select grid-point location where PsiVEL == 0.
950    o eesupp/src:
951       new S/R to calculate cumulated sum on tiled array, corner grid-cell location
952       (specific S/R needed with exch2 topology - for now, just print an error msg)
953    o pkg/shelfice
954     - Implement friction velocity-dependent transfer coefficients following
955       Holland and Jenkins, JPO, 1999
956       Original code by M. Losch with small modifs.
957       Enable with CPP option SHI_ALLOW_GAMMAFRICT
958       and runtime flag SHELFICEuseGammaFrict
959    o verification lab_sea & global_ocean.cs32x15:
960     - use tools/xmakedepend (instead of cyrus_makedepend, in genmake_local):
961       does not miss some dependencies (but is slower) and also works with many files
962       (default makedepend limitation for AD built).
963     - use cyrus_makedepend in adjustment.128x64x1 (so that it still tested).
964    o pkg/diagnostics:
965     - add run-time parameter "useMissingValue" (def=False) to fill land-point
966        (i.e., where mask=0) with MissingValue ; used only in MNC output file.
967       This replaces CPP-option DIAGNOSTICS_MISSING_VALUE.
968     - Extend the use of "missing_value" setting from data.diagnostics for the case
969       of counter-diagnostics (where fraction-weight is zero). This applies both to
970       MNC and MDS output files.
971    o pkg/seaice/seaice_growth.F:
972      - add 'a priori' cap of latent heat flux based on actual mass considerations
973        when SEAICE_ADD_SUBLIMATION_TO_FWBUDGET is used in conjunction with the
974        non-legacy seaice_solve4temp.
975      - add diagnostic of the residual sublimation freshwater flux (the freshwater
976        flux taken from the ocean if the total actual latent heat fluxes exceed
977        the maximum)
978      - remove the CPP switch around the *_FWbySublim unit change and move diagnostic
979       fill for SIatmQnt, SIfwSubl, SIatmFW to the end of seaice_growth.F.
980      - add diagnostic of the actual sublimation freshwater flux (that is 0. ifndef
981       SEAICE_ADD_SUBLIMATION_TO_FWBUDGET) and of the latent heat flux (evap+sublim).
982      - bug fix : frWtrAtm needs a_FWbySublim ifdef SEAICE_ADD_SUBLIMATION_TO_FWBUDGET.
983      - bug fix : missing part to Martin's r_FWbySublim pathological case fix.
984    o verification 1D_ocean_ice_column:
985       made model domain truly 1x1x23 instead of 5x5x23 with only center cell (3,3,:) wet
986       update results
987    o pkg/diagnostics:
988     - Implement setting of "Post-Processed" diagnostics (corresponding to gdiag(5)='P')
989       which are not filled-up but computed from other diags ; In this case, the mate
990       diag points to the primary (filled-up) diag to used for post processing.
991     - Update Velocity-potential computation using post-processed diag framework.
992     ==> Change the ordering of fields and time-periods in MDS output file
993       when using periodic averaging: now writes one time record with the full set
994       of fields for this time period, then the next time reccord (it used to be
995       one field with the full set of time records then the next field).
996         Note: this is now similar to NetCDF (MNC) output file. <==
997    
998    checkpoint62z (2011/06/21)
999    o adjoint monitor:
1000     - Add adjoint monitor output for packages exf, seaice
1001       and update relevant testreport output
1002    o pkg/seaice:
1003     - re-order diags inits so that they appear in order in available_diagnostics.log
1004     - added diags: hsnow thermo. rates of change, area preceeding ridiging process,
1005       area/heff/hsnow preceeding thermodynamic growth/melt.
1006     - modified diag: SIdA; output actual effect, as the description states.
1007     - modified description: SIqneti, SIqneto, SIuheff, SIvheff, SIdAb*, HSNOW.
1008     - retired redundant diags: SIyneg, SIfice, SIsnwice, SIthdgrh.
1009       (SIyneg->SIdHbOCN; SIfice->SIdHbATC; SIsnwice->SIdHbFLO;
1010        and SIthdgrh->SIdHbOCN+SIdHbATC+SIdHbATO)
1011     - modified diags (2) : switch all SIdA*, SIdH*, SIdS* from delta to rates.
1012     - added diagnostics for seaice generic tracers (SItr*).
1013     - added SItrUnit and SItrNameLong run time param (for SItr* diags).
1014     - in diag names, replaced 'PrTh' abbrev. of 'preceeding thermo' with 'PT'.
1015     I. Fenty: 18-Jun-2011:
1016     Minor changes to seaice package:
1017     1) Retired old variables (A22, SEAICE_lhsublim, areaMax, areaMin, hiceMin) and
1018        added some new ones (SEAICE_area_reg, SEAICE_hice_reg, SEAICE_area_floor)
1019       - Differentiated "regularization variables" from "floor variables"
1020        * areaMin became SEAICE_area_reg (old A22) and SEAICE_area_floor
1021        * hiceMin became SEAICE_hice_reg (old hiceMin)
1022          (with _reg meaning regularization variable)
1023       - SEAICE_lhSublim becomes lhSublim, the sum of SEAICE_lhEvap and SEAICE_lhFusion
1024        so as to ensure energy conservation when going between phases
1025      - A22 was not used anywhere
1026     2) Changed regularization procedure for heffActual and hsnowActual to ensure
1027        well-boundedness and smooth adjoint in seaice_growth.F
1028     3) Fixed a bug where seaice_solve4temp would not recognize ice-free grid cells
1029        because the old regularization always set heffActual >= 0.05 cm
1030     4) Changed the model so that the default behavior is to put a small (10^-5) "floor"
1031        on AREA when HEFF > 0.
1032      - went from requiring ALLOW_PRECLUDE_INFINITESIMAL_AREA to be defined to
1033        requiring that DISABLE_AREA_FLOOR *not* be defined
1034     Affected verifications:
1035      - 1D_ocean_ice_column (output.txt output_adm.txt)
1036      - global_ocean.cs32x15 (output.seaice.txt output_adm.seaice.txt)
1037    o pkg/diagnostics:
1038      - move MNC code from diagnostics_out.F into new diagnostics_mnc_out.F (2 S/R).
1039      - rename S/R GETDIAG to DIAGNOSTICS_GET_DIAG and change type of 1rst argument
1040        (was _RL, now integer) with option = 0 to retrieve all levels.
1041      - add pieces of code to compute velocity potential at each level (new diagnostics
1042        PhiVEL, works only when UVELMASS & VVELMASS are also turned on);
1043        for now, using same params as CG2D (target-resisual, max Nb of iter ...).
1044      - fix few issues with counter diagnostics in diagnostics_setdiag.F &
1045        diagstats_setdiag.F (if diagnostic counter is itself a counter diag)
1046        and in diagnostics_fract_fill.F (do not need a valid pointer for the
1047        diagnostics counter-mate); check that definition of counter-diagnostic
1048        includes a valid counter-mate (in diagnostics_set_levels.F).
1049    o model/src (rStar):
1050      - add rStar scaling factor in diags_phi_hyd.F (similar to calc_grad_phi_hyd.F);
1051        affect solution only if z* with full pressure in EOS;
1052        update output of test-exp global_ocean.90x40x15.
1053    o pkg/seaice:
1054      - introduce siEps=1e-5 parameter
1055      - use areaMax in AREA update (part 4), consistent with ridging step (part 2.5).
1056      - re-organize SEAICE_ADD_SUBLIMATION_TO_FWBUDGET code.
1057      - introduce ALLOW_SITRACER and seaice_tracer_phys.F to handle generic seaice tracer.
1058        For now it covers, and was tested for, ice salinity and age (attached to HEFF),
1059        as well as ice cover age and ridging index (attached to AREA).
1060        For now the run time parameters (in data.seaice/SEAICE_PARM03) are
1061        SItrName (e.g. 'age') and SItrMate ('HEFF', which is the default, or 'AREA').
1062        Up to SItrMaxNum=3 tracers can be used simultaneously.
1063    o pkg/salt_plume:
1064      -introduce SPsalFRAC run time parameter that sets the fraction of the
1065       salt by-product of ice growth (SPsalFRAC*(1-SIsalFRAC)*salt typically)
1066       that gets vertically redistributed (fluxed down) by pkg/salt_plume.
1067    o model debug options:
1068      - Switch reading of debugMode from S/R INI_PARMS (parameter file "data", stored
1069        in PARAMS.h) to S/R EESET_PARMS (parameter file "eedata", stored in EEPARAMS.h).
1070      - Refine debug-msg printing selection (3 new levels):
1071        debugMode  : controls printing of debug messages (sequence of S/R calls).
1072        debugLevel : controls printing of algorithm-relevant auxiliary/debug messages
1073         debLevZero =  0 ; /* level of disabled aux. msg printing */
1074         debLevA =  1 ; /* level of minimum  aux. msg printing */
1075         debLevB =  2 ; /* level of low aux. print (report read-file opening)*/
1076         debLevC =  3 ; /* level of moderate debug prt (most pkgs debug msg) */
1077         debLevD =  4 ; /* level of enhanced debug prt (add DEBUG_STATS prt) */
1078         debLevE =  5 ; /* level of extensive debug printing */
1079        New debugLevel default: with default debugMode value (=F),
1080          = 2 (debLevB) or = 1 (debLevA) in case ALLOW_AUTODIFF is defined.;
1081          and if debugMode=T, default debugLevel = 4 (debLevD).
1082        Relation with previous settings:
1083         debLevB (=2) corresponds to former debLevA (=1)
1084         debLevD (=4) corresponds to former debLevB (=2)
1085        Note:
1086         a) if debugLevel=0, skip WRITE_GRID call when nIter0 > 0 (same as before);
1087         b) default debugLevel=1 is convenient in AD runs (avoid many file opening msgs);
1088            to recover previous default, set debugLevel=2 (e.g. AD-test hs94.1x64x5)
1089      - Add new parameter (printResidualFreq, read from PARM02 namelist) to print
1090        detailed CG solvers convergence; off (=0) by default, except if debugLevel=5.
1091    o pkg/obcs:
1092      - change OBCSfixTopo default from True to False (should not change the results);
1093        keep OBCSfixTopo=T in verification-exp. seaice_obcs.
1094    o pkg/thsice:
1095      - fix bug in thsice_calc_thickn.F (was introduced in version 1.18) in
1096        2nd layer seaice sublimation (unlikely to happen)
1097      - use Interior mask for OBCS in thsice_advection.F (similar to what is
1098        done in gad_advection & seaice_advection).
1099    o adjoint:
1100      bug fix spotted by Gael Forget:
1101      seaice_advection and thsice_advection still had
1102      legacy CPP options to avoid CS corner updates for adjoint
1103    o pkg/seaice:
1104      => Change some of the defaults (2011/05/29):
1105         - change SEAICEuseFluxForm default (from False to True)
1106         - change DIFF1 default (from 0.004 m/s to 0. m/s)
1107         And print warnings if DIFF1 is not set in data.seaice and centered
1108          avection scheme is used without any diffusion.
1109      also:
1110      - fix seaice_diffusion calls in default AdvScheme part of seaice_advdiff.F;
1111      - set SEAICEdiffKh[] default in the same way as SEAICEadvSch[]
1112      - stop if DIFF1<>0 with SEAICEadvScheme <> 2, if DIFF1<>0 with any
1113        other non-zero SEAICEdiffKh[] diffusivity, if SEAICEadvSalt=T with
1114        #undef SEAICE_VARIABLE_SALINITY, if SEAICEadvAge=T with #undef SEAICE_AGE.
1115      update results of test exp.:
1116         lab_sea: output.fd (switch to AdvScheme=33 with diffKh=20)
1117             output.hb87, output_adm.evp (SEAICEuseFluxForm=T and diffKh=200)
1118             output_adm.noseaicedyn (SEAICEuseFluxForm=T)
1119         offline_exf_seaice: output.seaicetd, output_adm (SEAICEuseFluxForm=T)
1120         seaice_obcs: output (SEAICEuseFluxForm=T)
1121      and prescribe old default for SEAICEuseFluxForm (=F) and DIFF1 (=0.004)
1122          for standard fwd & AD lab_sea tests (to keep the same output).
1123    o pkg/seaice/seaice_growth.F:
1124      - use Ian Fenty's capping formulas for actual ice
1125      thickness thoughout EVOLUTION branch.
1126      - put treatment pathological case #2) in CPP brackets
1127      (ALLOW_AVOID_INFINITESIMAL_AREA, undef by default).
1128      - update global_ocean.cs32x15 and 1D_ocean_ice_colum results accordingly.
1129    o pkg/seaice:
1130      - seaice_diffusion.F : remove the min(DX,DY) factor permanently;
1131      pass the Laplacian diffusivity (in m^2/s) diffKh as a parameter;
1132      also pass fac as a param, which can be 1. (to update the tendency
1133      field) or the time step (to update the field itself).
1134      - seaice_advdiff.F: for multidim, call seaice_diffusion with
1135      e.g. SEAICEdiffKhHeff and with fac=1; for single-dim, call
1136      seaice_diffusion with e.g. SEAICEdiffKhHeff and with fac=time step.
1137      - SEAICE_PARAMS.h, seaice_readparms.F, seaice_check.F :
1138      hooks to handle SEAICEdiffKhHeff, SEAICEdiffKhArea, etc.
1139    o pkg/seaice:
1140      diffusion with centered advection scheme (diffus.F & advect.F):
1141      - simplify S/R DIFFUS (put deltaT & DIFF1 factor outside, move EXCH outside)
1142        to just compute the laplacian of input-field.
1143      - unroll k loop (harmonic,biharmonic diff) in advect.F to save 1 exch call.
1144      - fix flux-form version in diffus.F to conserve tracer.
1145      update output of lab_sea.fd & lab_sea.hb87 (1rst set of modif affects
1146       machine truncation) and lab_sea.salt_plume (conservative flux-form modif)
1147    
1148    checkpoint62y (2011/05/26)
1149    o pkg/seaice:
1150     - seaice_growth.F : in EVOLUTION branch, always include
1151       a_QSWbyATM_cover in qnet (as it should be).
1152     - verification/global_ocean.cs32x15 : update results accordingly
1153       (output.seaice.txt output_adm.seaice.txt).
1154    o pkg/seaice + obcs:
1155     - use maskInW & maskInS in multi-dim advection and biharmonic diffusion:
1156       equivalent of assuming no tracer gradient outside the OB region.
1157       update output of seaice_obcs (uses DIFF1 <>0 => biharmonic diffusion)
1158     - remove calls to OBCS_COPY_TRACER after EXCH calls (no longer needed
1159       after changes above);
1160     - obcs+seaice cleaning: apply seaice-tracer OB values to tracer field
1161       only at OB location (instead of over a band of OLx width).
1162    o pkg/seaice:
1163     - fix wrong indices in old (non Flux-Form) diffusion default S/R diffus.F
1164       (dxG(I+1, ...) changed to dxG(I, ...), no impact on Lat-Lon grid)
1165    o pkg/obcs:
1166      - split header file "OBCS.h" into 4 separated files:
1167        OBCS_PARAMS.h, OBCS_GRID.h, OBCS_FIELDS.h & OBCS_SEAICE.h
1168       Note: OBCS_PARAMS.h & OBCS_GRID.h can be included without OBCS_OPTIONS.h
1169         (contain no conditional statement which depends on OBCS options).
1170      - move "useOBCSYearlyFields" from "data.obcs" (hold in OBCS_PARAMS.h)
1171        to parameter file "data.exf", namelist EXF_NML_OBCS (in EXF_PARAM.h).
1172    o ctrl, cost, grdchk & autodiff pkgs:
1173      - make options file more standard (like other {PKG}_OPTIONS.h file but
1174        with AD_CONFIG.h); clean-up some of the included header files.
1175    o pkg/obcs:
1176      - do not mask tracer when applying OB (tracer == 0 could generate problems)
1177      - apply tracer OB values to tracer field only at OB location (instead of
1178        over a band of OLx width)
1179      - clean-up obcs_apply_w.F & obcs_apply_eta.F (since less calls to these S/R)
1180      - remove OBCS_MULTIDIM_OLD_VERSION code in gad_advection.F and remove
1181        obcs_apply_tloc.F & obcs_apply_sloc.F
1182    o obcs in model/src:
1183      - call OBCS_APPLY_W only if NonHydrostatic.
1184      - call OBCS_APPLY_ETA only if NonLinFreeSurf.
1185      - reset dEtaHdt and wVel to zero outside OB interior region ;
1186      - leave tracer unchanged outside OB interior region: This has no effect
1187        on the solution but just to prevent unrealistic tracer value outside OB.
1188      - zero out velocity outside OB interior region: This has no effect on
1189        the solution but just to prevent unrealistic velocity outside OB.
1190    o obcs and non-lin free-surf:
1191       move call to OBCS_APPLY_R_STAR from update_r_star.F to calc_r_star.F
1192       and call to OBCS_APPLY_SURF_DR from update_surf_dr.F to calc_surf_dr.F
1193       + add argument "etaFld" to OBCS_APPLY_R_STAR & OBCS_APPLY_SURF_DR:
1194       this fixes missing EXCH + get consistent eta OB value (+ fix restart).
1195       update results of test-exp. exp4(nlfs).
1196    o exp4 (nlfs) test-exp:
1197       use OBC for Eta at Western & Eastern OB (to test prescribing Eta
1198       with NonLin-FreeSurf); update output.nlfs.txt
1199    o obcs and 2d/3d solver norm:
1200       use interior masks (maskInC) to cancel out cg2d & cg3d matrix coeff at OB
1201       and outside OB interior region (will allow to place OB further inside the
1202       domain). Depending on the domain, can affects cg2d-Norm (previous
1203       cancellation outside OB was only partial), e.g. in exp4 & obcs_ctrl,
1204       and cg3d-Norm (previous Norm was computed before canceling OB terms),
1205       e.g. in tutorial_plume_on_slope.
1206      - update output of exp.: exp4 (x2), obcs_ctrl and tutorial_plume_on_slope.
1207    o pkg rbcs:
1208      - split RBCS.h into 3 files: RBCS_SIZE.h, RBCS_PARAMS.h & RBCS_FIELDS.h
1209      - add capability to apply relaxation to horizontal velocity uVel & vVel.
1210    o pkg/grdchk: add gradient check for control variable xx_shifwflx
1211    o pkg/shelfice/shelfice_init_fixed.F
1212      fix CPP-flag combinations
1213    o pkg/seaice: Merge iceage code of Pierre Rampal
1214      * update/change/correct ice age calculations
1215      * add age updates for pathological cases
1216      Probably needs more testing...
1217    
1218    checkpoint62x (2011/05/13)
1219    o pkg/mom_vecinv:
1220       high-order vorticity scheme: use interior masks (maskInW & S)
1221       to zero-out (outside OB) gradient of vorticity.
1222    o verification exp.:
1223       turn on "useEnergyConservingCoriolis" (better discretisation) in exp.
1224       hs94.128x64x5 and seaice_obcs ; update results.
1225    o pkg/obcs:
1226      fix bug in OBeta for YZ sections in obcs_exf_load.F
1227    o pkg/ctrl, pkg/shelfice, and optim:
1228      - add new control variable xx_shifwflx (fresh water flux underneath ice
1229        shelves). This is almost as tedious as obcs-ctrl, because the
1230        variables needs its own mask.
1231      - add a cost function term that penalizes the deviation of xx_shifwflx
1232        from the first guess (zero) in analogy to other control variables
1233    o pkg/shelfice:
1234      - start basic adjoint
1235    o pkg/ctrl:
1236      - remove extra 2D field "for good measure" when initializing in
1237        ctrl_set_globfld_[xy/xz/yz].F
1238      - replace hard coded precision 32 (a bug) in ctrl_map_ini_gen by ctrlprec
1239      - improve error messages in ctrl_set_unpack_*
1240    o OBC implementation in momentum:
1241       use interior masks (maskInC,W & S) in momentum S/R:
1242       - multiply divergence, tension and some del^i.u or del^j.v by maskInC
1243       - multiply del2u,del2v by maskInW/S (biharmonic viscosity)
1244       - multiply horiz. grad of vorticity by maskInW/S (in Leith scheme)
1245       - multiply gradient of wVel by maskInW/S in del2w calculation (NonHyd)
1246       Motivation: fix/clean implementation of OBC with biharmonic-viscosity
1247        (and also with Leith/Smagorinsky harmonic-viscosity).
1248       Update output of experiment dome and exp4 (+nlfs).
1249    o exp4 test-exp:
1250      - turn on: nonHydrostatic, exactConserv, viscA4 (with momDissip_In_AB=F)
1251        and prescribe time-varying OB (without pkg/exf) for zonal-velocity
1252        at Western & Eastern Boundaries (+/- 1 per-cent); Also prescribe
1253        time-varying OB at Western-side for wVel (NonHyd); update output.
1254      - add secondary set-up (.nlfs) using NonLin FreeSurf (z*) + mom_vecinv
1255        and biharmonic-viscosity ; also use prescribed time varying OB.
1256    o pkg/obcs:
1257      fix bug in OBWeta,OBWeta indices in obcs_apply_r_star.F
1258    o model/src:
1259      - fix startTime setting when baseTime<>0 & nIter0=0 are specified ;
1260      - initialise startTime & nIter0 with unlikely values: allows to set one
1261        from the other without ambiguity.
1262    o seaice_obcs test-exp.:
1263      add small diffK4T,S to test biharmonic diffusivity with OBCS ; update output.
1264    o pkg/obcs:
1265      - remove calls to OBCS_COPY_TRACER after EXCH for T,S & pTracer:
1266        no longer needed with maskInC,W,S in pkg/generic_advdiff.
1267    o pkg/seaice:
1268      - retired SEAICE_SALINITY and SEAICE_salinity in favor of
1269        SEAICE_VARIABLE_SALINITY and SIsalFRAC, respectively.
1270      - fixed bug in the initialization of sea ice salinity variable HSALT
1271        in seaice_init_varia.F  (removed dependence on ICE2WATR)
1272    o fizhi-cs test exp.:
1273       switch reference output convention for these 2 non-standard test-exp,
1274        from: pgi  6.1-5 on faulks (FC.6, -of linux_ia32_pgf77+authors_fc5)
1275          to: ifort 11.1 on baudelaire (FC.13, -of linux_amd64_ifort11)
1276       reason: faulks might get retired soon and pkg/fizhi has still Pb with gfortran
1277    o model/inc:
1278      - change type of PmEpR array (from _RS to _RL) to fix restart (with "-use_r4")
1279        of exp. global_ocean.90x40x15 (Suncronous time-stepping + Real-FW + NonLin-FS)
1280    o pkg/seaice:
1281      - fix calculation of saltFlux and saltPlumeFlux when using SEAICE_SALINITY
1282    o verification/lab_sea, 1D_ocean_ice_column, seaice_obcs, global_ocean.cs32x15
1283      - updated output*.txt files due to bug fixes in salt, saltPlumeFlux,
1284        and initial HSALT
1285    
1286    checkpoint62w (2011/04/26)
1287    o pkg/mom_fluxform:
1288      - fix calculation of del2u & del2v (no-slip BC) when using Non-Lin Free-Surf.
1289      - use parameter "sideDragFactor" in no-slip BC side-drag part.
1290      - update output of exp. global_ocean.90x40x15
1291    o pkg/mom_vecinv:
1292      mask del2u & del2v (no effect on results, but cleaner & closer to mom_fluxform)
1293    o update seaice exp.:
1294      use more consistent parameter values (remove "backward compatability only":
1295       ICE2WATR, SEAICE_lhSublim, SEAICE_cpAir, SEAICE_rhoAir + set rhoConstFresh)
1296      related to thermodynamics seaice. Update output (fwd+AD) of exp.:
1297       1D_ocean_ice_column (x2), lab_sea (x8), ioffline_exf_seaice (x2) & seaice_obcs
1298    o update test-exp global_ocean.90x40x15:
1299      o use default CD_CODE_OPTIONS file (Adams-Bashforth on CD Mom & Coriolis).
1300      o increase Overlap size from 2 to 3 (to allow to test bi-harmonic Visc.)
1301      o new pickup-files from a 100.yr run with pkg/down_slope (input.dwnslp params)
1302      o turn on zStar & viscA4 in standard set-up (dir input/)
1303        and update output files: output.txt & output.dwnslp.txt
1304    o new AD-test experiment: obcs_ctrl
1305      (From Matt MITgcm_Contrib/SOSE/BoxAdj) to test OBCS as control vector.
1306    o pkg/dic:
1307      fix two bugs in handling water vapour pressure in carbonate chemistry
1308      and air-sea fluxes. Found by Val Bennington and Galen McKinley
1309      (add DIC Option = WATERVAP_BUG to recover old results)
1310      update output of tutorial_global_oce_biogeo (fwd+AD) & tutorial_dic_adjoffline
1311    o adding allowInteriorFreezing option to check for water below freezing point
1312      at depth and bring the negative heat anomaly to the surface level
1313    o pkgs _fields_load:
1314      - extend GET_PERIODIC_INTERVAL to deal with non-periodic case (from pkg/rbcs)
1315      - use new S/R GET_PERIODIC_INTERVAL in pkgs:
1316        bulk_force, cheapaml, cfc, dic, obcs (+ ctrl/ctrl_get_gen_rec), offline and
1317        rbcs to get interpolation weights and time reccord number.
1318      - fix multi-threading in aim_fields_load.F
1319      - apply EXCH to temp arrays [0,1] after reading in dic_fields_load.F
1320    o external_fields_load:
1321      new S/R GET_PERIODIC_INTERVAL to calculate which time-record (and linear
1322       interpolation weights) to use in a periodic time-series ; do not divide by
1323       time-step to convert to integer:
1324       - this fixes case where externForcingPeriod is not multiple of time-step
1325          (Thanks to Christopher L. Wolfe)
1326       - this fixes case where externForcingPeriod is an odd multiple of time-step
1327         (was wrong by half of time-step); update results of tutorial_global_oce_in_p.
1328      store index of time-record which is currently loaded:
1329       - works without any assumption on sequence of calls to EXTERNAL_FIELDS_LOAD ;
1330       - needed for the adjoint but not yet used because of extensive recomputations;
1331         (to be fixed soon)
1332    
1333    checkpoint62v (2011/04/02)
1334    o verification/1D_ocean_ice_column added to test Ian Fenty's
1335      pkg/seaice_growth.F modifications for improving sea ice code differentiability
1336    o update output of exp4, internal_wave, seaice_obcs, tutorial_plume_on_slope
1337      (new velocity statistics after changing maskInW & maskInS definition)
1338    o pkg/generic_advdiff with OBCS:
1339      use maksInW & maskInS in advective flux and in biharmonic diffusion calculation:
1340      equivalent to assumption of no tracer gradient outside the OB region.
1341      This will affect the results if using obcs+biharmonic diffusion.
1342      update output_adm.txt of experiment bottom_ctrl_5x5 (not expected since no obc)
1343    o pkg/obcs:
1344      change definition of maskInW & maskInS: leave OB edges inside (maskIn=1)
1345      (e.g., maskInW(OB_Ie)=1 ) so that velocity normal-component at OB is still
1346      in Interior region. No impact on solution but affects Velocity monitor stats.
1347    o pkg/ptracers (adjoint)
1348      New option AUTODIFF_PTRACERS_SPLIT_FILES for writing separate
1349      tape file for each tracer
1350    o model/inc/src and pkg/autodiff: add parameters that allow to turn
1351      of parts of the adjoint code at run time. For now, there are only
1352      useKPPinAdMode, useGMrediInAdMode, and useSEAICEinAdMode. These
1353      parameters are set in data.pkg.
1354      This is the lazy coward's version of doing this, but still useful for
1355      debugging. In order to do it right, everything needs to be moved to
1356      pkg/autodiff.
1357    o pkg/autodiff: fix global_sum_tile_ad.F by resetting adsumPhi at
1358      the end; this fixes the adjoint balancing code for open boundaries.
1359    o pkg/ctrl:
1360      - change behavior of xx_${varname}period to be analogous to exf-conventions:
1361        xx_${varname}period =   0.,  means time-independent control part
1362        xx_${varname}period = -12., means one-year-periodic monthly control part
1363      - introduce helper routine ctrl_init_rec (part of ctrl_init.F) to
1364        clean up ctrl_init a little, remove unused variables
1365      - ctrl_init: fixed the handling of the start/endrec for obcs-variables
1366      - move "call cal_GetMonthsRec" from s/r ctrl_get_gen to s/r ctrl_get_gen_rec
1367    
1368    checkpoint62u (2011/03/15)
1369    o model/src:
1370      - for the adjoint, change NonLin-FreeSurf initialisation sequence: fill-in
1371        h0Fac from INITIALISE_FIXED and reset hFac to h0Fac in INITIALISE_VARIA ;
1372      - in initialise_varia.F (except for ALLOW_DEPTH_CONTROL) remove 2nd call to
1373        INI_DEPTHS, INI_MASKS_ETC & INI_LINEAR_PHISURF.
1374    o pkg/ctrl/obcs/ecco:
1375      - remove obsolete, unused, and partially broken code:
1376        ctrl_obcsvol/ctrl_obcsbal/ctrl_volflux and code within
1377        ALLOW_CTRL_OBCS_BALANCE
1378      - put a stop statement into ecco/cost_obcsvol.F, but also add
1379        cost_obcsvol to ecco_ad_diff.list
1380    o pkg/ecco: fix counting cost function contributions for obcs (code
1381      by Matt M.) and diffkr for diagnostics
1382    o pkg/ecco, pkg/ctrl, pkg/grdchk:
1383      add cost penalty terms for initial uvel, vvel, eta controls
1384      and I/O for prior error files
1385    o pkg/mdsio:
1386       move mds_check4file.F from eesupp/src to mdsio_check4file.F ; add option
1387       (new argument) to check for tiled file in mdsioLocalDir : this fix the
1388       restart from pickup_som , pickup_dic (& dic_co2atm) with mdsioLocalDir.
1389    o pkg/ctrl:
1390     - ctrl_obcsbal.F, ctrl_obcsvol.F: replace last calls of ctrl_getrec by
1391       ctrl_get_gen_rec, put a stop statement into ctrl_getrec. Remove
1392       unused and superfluous variables
1393     - ctrl_get_gen_rec.F: catch the case of xx_genperiod=0.
1394    o pkg/ecco
1395     - enable adjoint of Stevens OB
1396    o pkg/ctrl/ecco/grdchk:
1397      - remove global declaration of tmpfldx/yz and tmpfldx/yz2.
1398        Fortunately, we do not have any tests for the numerous cpp-flagged
1399        option of "obcs as control parameters" so we will never know
1400        if this is an improvement (but at least now things compile).
1401      - remove an obsolete initialization from ecco_cost_init_barfiles.F
1402      - fix some problems within never used ifdefs to make the code compile
1403    o pkg/obcs:
1404     - Refine Interior mask definition to work with more complex OB (e.g.
1405       if OB_Ie < OB_Iw); In case default setting is not sufficient, allows to
1406       read in Interior mask from file. Check if Interior mask is consistent
1407       with OB list of indices.
1408    o pkg/seaice
1409     - beginning code for a seaice tracer package,
1410       but currently only used for seaice age: SEAICE_AGE
1411       SEAICE_num = 4
1412       iTracer = 1: area-weighted ice age
1413               = 2: volume-weighted ice age
1414               = 3, 4: template for one-year vs. multi-year ice
1415       data.seaice has new namelist SEAICE_PARM03 for arrays related to
1416       SEAICE_num
1417    
1418    checkpoint62t (2011/03/05)
1419    o pkg/obcs:
1420     - obcs_apply_uv.F: change to a 2 steps method, first tangential component;
1421       then normal component. This ensures that the normal component is set
1422       correctly even when it conficts with tangential setting from an other OB.
1423       Affects results of test-experiment seaice_obcs: update the output.txt
1424    o pkg/obcs:
1425     - add code to monitor statistics of dynamical fields at OB.
1426     - take OBCS_BALANCE code out of obcs_calc.F into new S/R OBCS_BALANCE_FLOW :
1427       - fix to OBCS_BALANCE code (right hFac ; deal with simple OB intersection).
1428       - change default: balance the Net inflow through all OB (instead of balancing
1429         each OB separately); keep the old method if setting OBC_balanceFacX < 0.
1430     - switch on useOBCSbalance in dome experiment: only correct Western OB outflow
1431       to match Nortern OB inflow (OBCS_balanceFacN=0).
1432    o pkg/seaice:
1433     - redefined actual sea ice age to be ICEAGE/HEFF ifdef SEAICE_AGE_VOL
1434    o pkg/seaice (seaice_growth v 1.113):
1435     - reverting seaice_growth to v 1.111 in order to have code with exact bit
1436       compatibility with MITgcm_contrib/ifenty/Fenty_seaice_thermo_code_merge
1437       CPP option SEAICE_OCN_MELT_ACT_ON_AREA removed in v 1.112 is reintroduced
1438       runtime flag SEAICEareaFormula is kept but is inactive
1439    o model/src:
1440     - add new param to scale curvilinear grid distance and area when using
1441       a different sphere radius from the grid-files.
1442     - test/check multi-threads EXCH applied to local variable (cg2d_x)
1443    o adjoint:
1444     - enable adjoint of Stevens OB
1445     - add dummy_in_dynamics to enable extraction of ADJrhoinsitu
1446       (a bit delicate because of potentially modified adj. common block structure;
1447       current switch is ALLOW_AUTODIFF_MONITOR_DIAG, could be changed later)
1448    
1449    checkpoint62s (2011/02/15)
1450    o pkg/seaice (seaice_growth v 1.112):
1451     - introduce SEAICEareaFormula run time parameter, which selects the recipe for
1452       computing the ice cover tendency from effective thickness tendencies. Include
1453       Ian Fenty's formula.
1454     - remove 'undef SEAICE_OCN_MELT_ACT_ON_AREA' which may now be achieved using
1455       SEAICEareaFormula.
1456     - simplify notations for the various d_HEFF/d_AREA terms.
1457    o pkg/gmredi:
1458     - add Boundary-Value-Problem bolus transport (Ferrari etal, OM 2010) code
1459       from Christopher Wolfe (UCSD); add partial cell factor in vertical derivative;
1460       add a verification test-run (front_relax.bvp) to test GM_useBVP.
1461    o pkg/seaice (seaice_growth v 1.111):
1462     - for SEAICE_DO_OPEN_WATER_GROWTH, replace Gael's implementation with Ian's.
1463     - the new SEAICE_DO_OPEN_WATER_MELT allows open-water air-sea heat fluxes to
1464       also melt ice.
1465    o pkg/seaice:
1466     - McPhee formula for Ice-Ocean fluxes (provided by Ian Fenty).
1467     - can be used by #define MCPHEE_OCEAN_ICE_HEAT_FLUX in SEAICE_OPTIONS.h
1468    o pkg/cheapaml:
1469     - from Nico Wienders: New version of this package.
1470    o pkg/flt:
1471     - add CPP options to prevent floats to re-enter the opposite side of
1472       a periodic domain (default: keep periodicity)
1473    o pkg/gmredi:
1474     - apply exchange to GM_PsiX,GM_PsiY to get valid values near CS-corners
1475       (needed for multi-dim advection).
1476     - switch on GM Advective form in global_ocean.cs32x15 and update output.txt
1477    o model/src:
1478     - fix wrong re-setting of addMass array (ALLOW_ADDFLUID) for atmospheric run.
1479    o tutorial_tracer_adjsens
1480     - extend to NLFS and replace maskC by hFacC
1481       (change reference output accordingly)
1482    
1483    checkpoint62r (2011/01/24)
1484    o testreport:
1485     - add option -deloutp (-do) to remove output file after successful run
1486     - add option -mfile (-mf) for MPI machile-file and for each test-exp,
1487       extract exact list of procs from this file ; adjust COMMAND by
1488       replacing TR_MFILE & TR_NPROC with local machile-file & Nb of MPI procs.
1489    o pkg/ecco: replace old ineffective way of penalizing deviations from
1490      first guess (of obcs) with code by Matt Mazloff
1491    o pkg/ctrl: add code that allows the use of ALLOW_OBCS?_CONTROL without
1492      exf/cal
1493      - ctrl_init: fix initialisation (computation of diffrec) for obcs-ctrl
1494        and handle case of obcs?period == 0
1495        Not affected by these changes: There is still an inconsistency in
1496        the computation of start/endrec for the obcs variables for ALLOW_CAL
1497        defined (see comment by Menemenlis, 7-Mar-2003)
1498      - make S/R ctrl_get_gen_rec return something meaningful even if
1499        ALLOW_CAL is not defined
1500      - ctrl_getobcs?: simplify code so that it does not need to use
1501                       S/R exf_swapfields
1502    o testreport:
1503       allow to test MPI with different number of processors for each experiment:
1504       create file "SIZE.h.mpi" in each build dir.
1505       Note: update of "-command" argument not yet implemented.
1506    o model/src, pkg/autodiff, pkg/ecco, pkg/seaice:
1507      alleviate the need for additional 3D tapes when using
1508      the non-inear free surface in the adjoint. This is done
1509      by adding an 'update' of hfacc etc. to their current
1510      value at the beginning of forward_step.F.
1511    o pkg/seaice
1512      seaice_lsr: move stress-divergence computations out of outer pseudo-
1513      timestepping loop
1514    o pkg/obcs/obcs_prescribe_read.F: move 'CALL OBCS_EXTERNAL_FIELDS_LOAD'
1515      up, so that the calls of the ctrl_* subroutines are really at the end
1516      of the routine.
1517    o pkg/gmredi:
1518      allow to specify a 2-D horizontal map and a 1-D vertical profil
1519      as scaling factor for Isopycnal diffusivity (Redi) and GM diffusivity.
1520    o pkg/seaice:
1521      move lsr iterations from seaice_dynsolver to seaice_lsr.
1522    o pkg/seaice:
1523      reduce memory footprint of seaice mutldim advection tapes,
1524      by using a 2D tape independent of the generic_advdiff ones,
1525      and setting GAD_AREA=1 etc. rather than GAD_AREA=101 etc.
1526    
1527    checkpoint62q (2010/12/29)
1528    o model/src:
1529      - check horizontal grid-spacing for unset or zero/negative values.
1530      - change AD test hs94.1x64x5 to be truly a 2-D set-up.
1531    o pkg/flt:
1532      - use (recent) mdsio S/R MDS_READVEC_LOC instead of local FLT_MDSREADVECTOR
1533      - precision of input and output files set according to readBinaryPrec
1534        and writeBinaryPrec (previously always 64.b), pickup remains at 64 bits.
1535      - initial float position from tiled file was not converted to index space
1536        (looks like a bug): fixed to make it similar to initial pos. global file.
1537    o global_ocean.cs32x15:
1538       change SIZE.h of AD set-up to get same tiling as with MPI.
1539       Update output_adm, output_adm.thsice (pass@14) & output_adm.seaice (fail@11)
1540    o model/src:
1541       add flag to control printing of domain fields (bathymetry, hFac ...) in
1542       ini_mask_etc (call to plot_fieds_xy*).
1543    o pkg/thsice:
1544       if useEXF, some forcing fields are not valid in overlap: fixed by computing
1545       over the interior only + apply EXCH at the end (like with SEAICE advection).
1546    o pkg/mdsio:
1547      - add 2 arguments to S/R MDS_PASS_R4/8toRL/S for overlap size of buffer
1548        to copy to/from, so that it can be used to replace MDS_PASS_WH_R8toRL/RS.
1549      - change barrier call for safe multi-threads access to 3-D shared buffer.
1550      - MDS_READ/WRITEVEC_LOC use buffers from MDSIO_BUFF_3D.h (instead of local ones)
1551      - replace call to MDS_PASS_WH_R4/8toRL with call to MDS_PASS_R4/8toRL and
1552        remove the 4 S/R MDS_PASS_WH_R4/8toRL/S.
1553    o pkg/flt:
1554      - add fourth-order Runge-Kutta integration
1555      - add basic exch2 support (only 1 facet supported so far!)
1556    o pkg/mdsio+rw:
1557      new S/R to read local (or tile independent) vector (read counterpart of
1558       mds_writevec_loc, and front-end write_glvec_rl/rs).
1559    o global_ocean.cs32x15: additional input_ad.seaice experiment
1560        that uses pkg/seaice rather than pkg/thsice.
1561        (using multidim advection for seaice)
1562    o towards more F95 syntax for array specification in namelist:
1563      - change "data.diagnostics" (data.ptracers was changed before checkpoint62p)
1564        of all verification experiments.
1565           e.g.:    line: fields(1,3)='ETAN    ','ETANSQ  ',
1566          was changed to: fields(1:2,3)='ETAN    ','ETANSQ  ',
1567      - finish adding "-DNML_EXTENDED_F77" to DEFINES list in pgf77 and g77 optfiles
1568    o global_ocean.cs32x15: additional input.seaice experiment
1569        that uses pkg/seaice rather than pkg/thsice.
1570    
1571    checkpoint62p (2010/12/17)
1572    o pkg/thsice: rename (ad tape index) iicekey as ticekey, and move it
1573        to THSICE_SIZE.h to avoid conflict with pkg/seaice.
1574    o pkg/seaice: add seaice_diffusion.f seaice_map_thsice.f to adjoint.
1575        allow for use of multim. advection in seaice adjoint.
1576    o pkg/seaice: add diagnostics for snow precipitation and sublimation flux
1577      - first attempt to close budgets by taking into account the freshwater
1578        flux implied by the sublimation of snow and ice. So far only the
1579        volume budget is closed, turn on with soon-to-be-retired-again CPP-Flag
1580        SEAICE_ADD_SUBLIMATION_TO_FWBUDGET
1581    o eesupp/src:
1582      new S/R with new option (NML_EXTENDED_F77) to change array specification
1583      from F95 standard to commonly accepted extended F77 form.
1584      This would allow to use F95 syntax in namelist (needed with gfortran 4.4.5)
1585      and to revert back to the original syntax (with -DNML_EXTENDED_F77)
1586      for less tolerant f77 compiler (e.g., pgf77, g77).
1587    o globalFiles:
1588      commented out in parameter file "data" since it's not safe with MPI
1589      (e.g., wrong on aces); keep it if useSingleCpuIO=T (but not doing much
1590      in this case); no longer commented out in restart test (tst_2+2).
1591    o add adTapeDir to specify a special directory where adjoint tapes are
1592      written/read (adread_adwrite.F). adTapeDir is specified in data/PARM05
1593      and cannot be used together with mdsioLocalDir.
1594    o nesting pkgs:
1595      - packages_init_variables : put call to OBCS_INIT_VARIABLES in last position
1596      - update Gianmaria's Nesting pkgs (from Contrib/nesting_sannino)
1597      - add parameter files + utils dir + output from short run on beagle.
1598    o pkg/seaice:
1599        fix seaice_growth.F store directives; update results of exp. lab_sea.ad
1600    o pkg/seaice: explicitly store tsurfloc in seaice_solve4temp.F to avoid
1601      unnecessary copying in adjoint code, requires new parameter NMAX_ITER
1602    
1603    checkpoint62o (2010/11/25)
1604    o pkg/exf:
1605      - change CPP option EXF_VERBOSE to run-time logical param exf_verbose.
1606    o pkg/seaice:
1607      - seaice_ocean_stress: split a loop for better vectorization of the
1608        adjoint code
1609      - seaice_growth.F: fix bug in conservation of freshwater connected to
1610        capping of heff, put contribution into d_HEFFbyNEG
1611      - replace irritating parameters SEAICE_latentWater/Ice and SEAICE_sensHeat
1612        by something more sensible (parameters that are what their name implies)
1613      - change some defaults, so that by default exf-parameters are used for
1614        things like rhoAir, cpAir,latent/sensible heat parameters, in order
1615        to reproduce the old results, many data.seaice now contain funny values
1616        for cpAir and latent heat of sublimation
1617    o packages_readparms.F: move exf_readparms up in line so that
1618        exf-parameters are visible for other packages (e.g. seaice)
1619    o debugMode & debugLevel=2:
1620      - differentiate between debugMode & debugLevel=2:
1621        debugMode: controls printing of debug messages (sequence of S/R calls).
1622        debugLevel: controls printing of algorithm intermediate results and stats.
1623      - remove "if debugLevel=2 => debugMode" but keep "debugMode =>  debugLevel=2";
1624        => allows to print debug-stats without all sequence of call messages.
1625      - switch control of debug print from debugLevel to debugMode in many S/R.
1626    o pkg/obcs (obcs-sponge):
1627        fix bug that was introduced on Oct 25 (in dynamics.F v1.151): put back the
1628        call to OBCS_PRESCRIBE_EXCHANGES (need to exch gU,gV when using obcs-sponge)
1629    o pkg/generic_advdiff:
1630      - record overlap minimum size for each advection scheme;
1631      - refine criteria on overlap minimum size;
1632      - check and stop (in gad_check) if overlap size is too small.
1633    o pkg/obcs:
1634      - with ptracers: remove multiple calls to obcs_apply_ptracer (only done
1635        once, in ptracers_implicit.F)
1636      - with seaice: remove test on empty file name in obcs_apply_seaice (always
1637        apply OB values when tile has OB)
1638    o model/src, coriolis setting:
1639      - integer parameter "selectCoriMap" (=0,1,2) replaces 3 logical
1640        useConstantF, useBetaPlaneF, useSphereF ; can now read coriolis from
1641        files (selectCoriMap=3) with any grid.
1642      - add parameter "fPrime" for constant second Coriolis coeff (default=0).
1643    o pkg/seaice/seaice_growth.F:
1644        a few cosmetic changes that reduce the number of lines of code
1645    o pkg/obcs: add boundary conditions following Stevens (1990)
1646      - the code follows old MOM/NAOSIM code
1647      - so far it is only implemented for the eastern and western boundaries
1648        and NOT for pTracers
1649    o pkg/rbcs:
1650      - replace rbcsInIter by rbcsForcingOffset, the time in seconds at the
1651        beginning of the first rbcs forcing period.
1652      - add option rbcsSingleTimeFiles that makes rbcs read forcing data like the
1653        offline package, i.e., one file per time, labeled by iteration number;
1654        deltaTrbcs sets the timestep with which the data was generated;
1655        rbcsIter0 is the forcing iteration corresponding to rbcsForcingOffset.
1656      - rbcsForcingCycle=0 makes forcing non-cyclic.
1657      - make arithmetic safe for negative times and odd forcing periods.
1658    
1659    checkpoint62n (2010/11/09)
1660    o pkg/seaice:
1661        fix masking in free-drift S/R ; update results of exp. lab_sea.fd
1662    o pkg/obcs:
1663       New S/R to copy tracer value from the OB location to narrow band region
1664        (width = same as overlap) beyond the OB: preserve OB value (needed for
1665        high-order scheme) which were overwritten by EXCH call if in overlap
1666        region. Applied to theta, salt, ptracer and advected seaice variables.
1667       With seaice: use maskInC in similar way as in gad_advection.F,
1668        in seaice_advection.F and advect.F.
1669       Update output of experiment seaice_obcs and change exp4 to test OBCS with
1670        4th order Adv.Scheme. for pasive salt and ptracer.
1671    o tools/genmake2:
1672      - when looking for an optfile (not specified), only search for Fortran compiler
1673        (remove sym-link test + setting of CPP + makedepend check + C-compiler check)
1674      - in get_fortran_c_namemangling: use "$CC $CFLAG" to compile C test programm
1675        (instead of "$MAKE genmake_test.o" since an existing Makefile can be wrong)
1676      - set default for CPP to "cpp -traditional -P" (was the case without specifying
1677        an optfile, but otherwise default was just "cpp".
1678      - comment out PLATFORM=$p_PLATFORM (no idea where p_PLATFORM comes from)
1679      - when "CC" is not set in the optfile, look for possible C compiler
1680        (instead of just setting CC=cc)
1681      - put back version v.169 modif (from 2008/02/15), was dropped in v.173 changes:
1682        => add a ".F" to ".o" rule for source files with no "#include" (such as
1683           port_rand.F); otherwise, default ignores FOPTIM and just uses FFLAGS.
1684      - move gfortran before g77 in list of possible Fortran compiler (consistent
1685        with reference compiler switch from g77 to gfortran)
1686    o pkg/seaice:
1687      o remove SEAICE_OLD_AND_BAD_DISCRETIZATION-code, add a test to
1688        seaice_check that stops the model, when the CPP flag is used.
1689      o seaice_growth.F: make capping of ice volume conserving by returning the
1690        capped ice as freshwater to EmPmR. This does not change the verification
1691        experiments but will change runs where the capping is acutally active
1692    o change reference platform+compiler from faulks+g77 to baudelaire+gfortran
1693      (except the 2 fizhi test exp.); update output of exp.: bottom_ctrl_5x5,
1694         global_ocean.cs32x15 (icedyn, thsice, AD thsice), global_ocean_ebm (AD),
1695         lab_sea (fd, hb87, salt_plume), MLAdjust (3/5) and vermix (dd)
1696    o tools/genmake2:
1697      - merge genmake_warnings & genmake_errors into 1 log file: "genmake.log")
1698      - change DUMPSTATE default to false (can use "-ds" option to switch it to T)
1699      - clean previous genmake log files before anything else.
1700      - change Makefile to remove testreport log files (*.tr_log) and genmake log
1701        files only with "CLEAN" target (instead of "Clean");
1702    o pkg/generic_advdiff:
1703      Change OBCS in multiDim advection (gad_advection.F):
1704       Use maskInC to prevent intermediate update of tracer-field in OB regions,
1705       thus keeping current-time-step OB values; and remove the call to OBCS_APPLY
1706       which were applying future time-step OB values.
1707      This way, all explicit calculations use current-time-step OB values
1708       (simpler and more consistent).
1709      Affects results when set-up uses time-varying OBC and multi-dim advection;
1710       update output of experiment seaice_obcs.
1711    o pkg/seaice:
1712      move OPTIONS (formerly locally defined) to SEAICE_OPTIONS.h:
1713       this includes SEAICE_GROWTH_LEGACY (+ SEAICE_DO_OPEN_WATER_GROWTH &
1714         SEAICE_OCN_MELT_ACT_ON_AREA ) and SEAICE_SOLVE4TEMP_LEGACY.
1715      Default (pkg/seaice/SEAICE_OPTIONS.h) is to define SEAICE_SOLVE4TEMP_LEGACY
1716       but leave SEAICE_GROWTH_LEGACY undef ; For now, keep verification exp
1717       unchanged (SEAICE_GROWTH_LEGACY defined in */code*/SEAICE_OPTIONS.h)
1718    o pkg aim (2010/10/26):
1719      - Introduce ALLOW_INSOLATION, moving toward a more general incoming solar radiation
1720        formulation with obliquity, eccentricity, ... as run-time parameters,
1721      - Introduce diagnostics for top-of-the-atmaophere incoming solar radiation and
1722        upward shortwave radition at the surface (all-sky and clear-sky).
1723    o pkg/obcs:
1724      - writing sections with globalFiles=T does not work: switch to tiled-files
1725        when writing sections for OBCS (change pkg/rw/write_rec.F accordingly).
1726      - fix index bug (OB_Ie -> OB_Iw_) in obcs_apply_uvice.F
1727      - apply OBCS_SEAICE_COMPUTE_UVICE to both uice and vice at all obcs
1728    
1729    checkpoint62m (2010/10/21)
1730    o pkg/seaice: vectorize seaice_solve4temp.F
1731      - move iterations loops outside of i/j-loops
1732      - requires 2D arrays for TB and effConduct
1733      - add 2D iceOrNot to replace HICE_ACTUAL.GT.0, as HICE_ACTUAL is
1734        modified in this routine
1735      - a little bit of clean up, adjusting indentation, etc.
1736      - replaced a few TEN**a by exp(a*log(10.)) in new code for better
1737        performance and '**TWO' by '**2' (because TWO is a float),
1738        replaced ONE, ZERO
1739    o eesupp/src:
1740       fix flow dir for exch1_z_RX_cube, exch1_uv_RX_cube & exch1_bg_RX_cube
1741    o pkg/seaice/seaice_growth.F
1742      Revision 1.89 of seaice_growth.F completes the overall october 2010 revision and
1743      merging process. The merged routine has two branches, and one activates the 'evolution'
1744      branch by setting SEAICE_GROWTH_LEGACY to undef (at the top of the routine for now).
1745      In summary, here is what the '10/10 revision' did consist of
1746        part 1: seaice_growth.F revisions 1.71 to 1.75
1747          - Preliminary seaice_growth.F clean-up, keeping test results strictly unchanged.
1748            The emphasis here was on improving readability (e.g. by trying to use meaningful
1749            variable names) and modularity (e.g. by adding arrays to store heff etc. updates).
1750        part 1.5:
1751          - revising the lab_sea experiment to make it a more useful (i.e. stable
1752            and representative of an actual model run). This was done by generating a
1753            (winter) pickup to start from, switching back the main experiment dynamic
1754            solver from evp to lsr, having one of the experiments use the free drift solution.
1755        part 2: seaice_growth.F revisions 1.76 to 1.85
1756          - Sorting out hard-coded constants that prevented heat and fresh water conservation.
1757          - Sorting out the various fields units and sign (set early on and reset at the end)
1758            to avoid numerous scalings/re-scalings. By v1.85 the basic unit for ice, heat and
1759            fresh water stock is 'effective ice meters', and >0 implies more ice/snow.
1760          - Using tendency terms arrays (d_HEFF* etc.) to alleviate remaining code locks,
1761            and simplifying logical expressions to further improve readibility.
1762        part 3: seaice_growth.F revisions 1.86 to 1.89
1763          - Re-organize the blocks of code more logically.
1764          - Merging the '_if.F' pieces that add something new.
1765    o pkg/thsice:
1766      - vectorize thsice_solve4temp and thsice_get_exf.
1767        Problem: thsice_solve4temp has an unvectorizable statement that
1768        might also be problematic for TAF
1769      - thsice_get_exf: add the ALLOW_BULK_LARGEYEAGER04 CPP-flag. This
1770        does not change the verifcation experiment, but will change all
1771        experiments that have this flag undefined (not tested in verification);
1772        a little reorganization to save a few 2D fields and recomputations
1773      - 1st step of revisiting thsice adjoint (major recomp. sorted out)
1774      - 2nd step:  fix some store dirs
1775        o seems to work somewhat, i.e. using ifort but not g77
1776        o likely cause are incomplete init. or recomputation
1777        o start verification/global_ocean.cs32x15/input_ad.thsice
1778    o pkg/obcs: add support for exch2
1779      - the position of the boundary and prescribed values are specified using
1780        a global domain with exch2 facets stacked
1781        - in x for N,S boundaries (like W2_mapIO=-1)
1782        - in y for E,W boundaries (so E,W boundaries do not overlap)
1783    o pkg/mdsio: add support for writing global sections with exch2
1784        file layout is as for obcs described above:
1785        - for x-z sections, facets are stacked in x (like W2_mapIO=-1)
1786        - for y-z sections, facets are stacked in y
1787    o pkg/thsice:
1788       - change a few routines for better vectorization: thsice_albedo.F,
1789         thsice_step_temp.F, and in thsice_calc_thickn.F. Results are
1790         not affected, but in particular the latter routine has changed
1791         dramatically (not necessarily easier to read now).
1792       - re-arrange calculation in THSICE_SOLVE4TEMP: move outside of i,j loops
1793       iteration loop and call to S/R THSICE_GET_BULKF & THSICE_GET_EXF.
1794    o verification/lab_sea:
1795      - overhaul of the forward model experiments. The main motivation
1796        for this revision is that lab_sea has proven quite fragile (when
1797        changing the sea-ice code, and switching platforms) to a point
1798        when failures were very hard to attribute to specific code problems.
1799      - the suspected reason for this fragility is noise amplification by evp so,
1800        to start with, we decided to replace evp with lsr in the main experiment.
1801      - the input.lsr experiment thus became obsolete and was removed.
1802      - it was replaced with the input.fd experiment that uses an
1803        analytical "free drift" solution as the ice velocity field.
1804      - Taken together, input (lsr), input.fd (free drift) and input.hb87 (evp)
1805        will hopefully allow us to discriminate problems due to dynamic solvers
1806        from problems due to the thermodynamic code. input.salt_plume (lsr) allows
1807        us to test additional options, along with the salt plume package.
1808      - Finally a pickup was generated (at the end of a one year run) to
1809        make the tests more representative of an actual model run. Previously
1810        the tests starting point was a 1m thickness of ice everywhere.
1811    o pkg/seaice:
1812      - introducing S\R seaice_freedrift.F that compute the
1813        analytical solution to an approximate ice momentum
1814        equation (i.e. the simple stress/coriolis balance).
1815      - define SEAICE_ALLOW_FREEDRIFT to trigger the computation
1816        of the free drift velocity field, and enable its use.
1817        To actually use the free drift solution as the model ice
1818        velocity field set SEAICEuseFREEDRIFT to .TRUE. in data.seaice.
1819    o move "useOASIS" from PARAMS.h to EEPARAMS.h and read it from "eedata"
1820    
1821    checkpoint62l (2010/10/04)
1822    o pkg/seaice:
1823      -fix the USE_ORIGINAL_SBI version (for variable freezing point);
1824      -use "celsius2K" in SEAICE_VARIABLE_FREEZING_POINT and in new
1825       version (with USE_ORIGINAL_SBI undef);
1826    o add hooks for new packages OASIS, the package will follow
1827      (hooks exclude the seaice pkg for now)
1828    o pkg/autodiff: ALLOW_AUTODIFF_WHTAPEIO
1829      Option to use mdsio_read_whalos.F/mdsio_write_whalos.F,
1830      rather than mdsio_readvector.F/mdsio_writevector.F, within
1831      adread_adwrite.F to read/write adjoint-related tapes to disk.
1832    o eesupp and pkg/mdsio: ALLOW_WHIO
1833      Option to write/read 2D fields to files including tiles halos.
1834      The main purpose is for adjoint related "tape I/O".
1835      The secondary purpose is for debugging phases.
1836      A word on those rather specifically intended purposes.
1837      The code was meant to be stripped down to the bare minimum.
1838      Typically, there is a unique and basic mapping to the global
1839      buffer (tile by tile, then proc by proc, then level by level), and
1840      byteswaps and meta-files are omitted. Indeed the (*_WH*) code is not
1841      meant to generate user friendly outputs of various shapes and forms.
1842      Rather it is intended, for the knowledgeabale developers,
1843      to be largely independent of the many mdsio options, to allow
1844      outputs of tiles+halos in debugging phases and in adjoint runs,
1845      and to allow some flexibility in tuning (adoint) I/O depending on each
1846      file system behavior. With regard to tuning, most of the potential knobs
1847      (to leave files open, to allocate the I/O indep. of usesinglecpuio,
1848      to specify directories, to specify the typical size of I/O calls, etc.)
1849      are not yet included, and will be added if they prove useful.
1850    o pkg/seaice:
1851       fix uninitialised arrays in USE_ORIGINAL_SBI version of seaice_solve4temp.F
1852    o pkg/seaice:
1853       new S/R seaice_solve4temp.F: this is the merged version of Ian Fenty
1854       code (seaice_budget_ice_if.F) which enable to recover old standard
1855       code (seaice_budget_ice.F) when option USE_ORIGINAL_SBI is defined.
1856       temporary: add "#define USE_ORIGINAL_SBI" at the top of seaice_solve4temp.F.
1857    o model/src (rStar):
1858       use simple average (not area weighted) of rStarFac at U,V point when using
1859       vectorInvariant and selectKEscheme=1,3 (consistent with mom. vertical advection)
1860       update output of exp. fizhi-cs-32x32x40 and fizhi-cs-aqualev20.
1861    
1862    checkpoint62k (2010/09/17)
1863    o adjoint
1864       * changed verification/global_ocean.cs32x15 ; adjoint now tests
1865         Adams-Bashforth 3 + NLFS + RSTAR
1866       * some more modifs required for ECCO-GODAE v4
1867    o pkg/seaice
1868       add SEAICE_AGE_VOL option to use volume instead of area for
1869       integrating SEAICE_AGE
1870    o model/src:
1871       first check-in of sigma & hybrid-sigma coordinate code ; also includes
1872       non-linear free-surface parts ; but pressure-gradient not yet coded.
1873    o pkg/ptracers:
1874       option for ptracer to convert Salt Relax into additional EmP.
1875        tested in exp. global_ocean.90x40x15.dwnslp (update output)
1876    
1877    checkpoint62j (2010/08/25)
1878    o pkg/ggl90:
1879       other minor changes: remove 3-D temp array gTKE (+ add argument myIter)
1880    o pkg/dic: car_flux.F, phos_flux.F
1881      - reduce number of exp-calls in order to improve performance
1882      - clean up a little (replace fields by their macros, etc., fix
1883        typo in CPP-flag)
1884    o pkg/ggl90: minor changes
1885      - GGL90diffKrS was removed --> always use GGL90diffKr
1886      - GGL90viscAr was removed --> replaced with GGL90viscArU, GGL90viscArV
1887      - hack of mxlMaxFlag=2 --> ensure mixing between first and second level
1888        (commented out for now)
1889      - change in max/min operations to ensure that smoothing is ok
1890      - smoothing of GGL90viscAr was moved to ggl90_calc.F (as done for GGL90diffKr)
1891      - always use diffKrNrT as background profile (i.e. never use diffKr field)
1892    o pkg/cfc: bug fix, AREA(i,j,1,bi,bj) -> AREA(i,j,bi,bj)
1893    o pkg/dic:
1894      - model/src/impldiff.F: if TARGET_NEC_SX, extend loop ranges for better
1895        vectorization
1896      - small bug fix in insol for the unlikely case of a cartesian grid
1897      - towards vectorizing the dic package: bio_export.F, car_flux.F, phos_flux.F
1898        + now vectorize, which also removes adjoint recomputations;
1899        + replace integer maksp1 by _RL maskp1
1900        + replace a**x by exp(x*log(a)) in phos_flux.F for speed
1901    
1902    checkpoint62i (2010/07/21)
1903    o pkg/flt:
1904      - with OBCS: stop floats which enter the OB region
1905    o model/src:
1906      - use tempVertAdvScheme & saltVertAdvScheme (instead of horizontal ones)
1907        for implicit vertical advection.
1908    o pkg/seaice:
1909     - account for melting in seaice age evolution.
1910     - remove double counting of seaice ridging effect on seaice age.
1911    
1912    checkpoint62h (2010/06/18)
1913    o pkg/exch2:
1914     - remove exch2_*xy_rx files: call was replaced with exch2_*3d_rx(myNz=1).
1915    o tools/genmake2
1916      - remove "-pdefault" option: redundant with the use of "packages.conf";
1917      - remove file pkg/pkg_default : set the default as a pkg group
1918        ("default_pkg_list") defined in pkg/pkg_groups;
1919      - fix for case pkg/pkg_depend is missing (was hanging before);
1920      - add option "-pgroups" to specify a different pkg_groups than the default.
1921    o verification/adjustment.cs-32x32x1:
1922       add a "minimal" set-up test (code_min & input_min) which only compiles
1923       eesupp/src and the 2 pkgs (exch2 & debug) which don't need model/src & inc.
1924    o tools/genmake2
1925      - extend pkg_depend rules to model & eesupp (e.g., if model depend on [pkg]))
1926      - fix details of checking for mnc & profile pkg when NetCDF is unavailable.
1927    o pkg/exf: merge exf_bulk_largeyeager04 into exf_bulkformulae because these
1928      files are nearly the same anyway.
1929      Step 1: make exf_bulkformulae look like exf_bulk_largeyeager04:
1930       - redefinition of tau(i,i) (by a factor of ustar)
1931       - 1./exf(Const/T) -> exf(-Const/T) (big change in the results)
1932       - replace rhonil by rhoConstFresh in computation of evap (bug fix)
1933       - replace u/vstress=tau*rd*ws*cw by tau*rd*u/vwind (changes results)
1934       - replace
1935         rd(i,j)= rdn(i,j)/(exf_one - rdn(i,j)/karman*psimh )
1936         shn    = sh(i,j,bi,bj)*rd(i,j)/rdn(i,j)
1937         by
1938         shn    = sh(i,j,bi,bj)/(exf_one - rdn(i,j)/karman*psimh )
1939         (changes results)
1940       -> exf_bulkformulae v1.22,
1941          update verification experiments lab_sea, offline_exf_seaice, seaice_obcs
1942          (lab_sea: output.hb87.txt 1.11, output.lsr.txt 1.25, output.salt_plume.txt 1.13,
1943                    output.txt 1.63
1944           offline_exf_seaice: output.seaicetd.txt 1.7
1945           seaice_obcs: output.txt 1.10)
1946      Step 2: do the actual merge and remove exf_bulk_largeyeager04.F
1947       -> exf_bulkformulae v1.23,
1948          unfortunately requires updating lab_sea.salt_plume (6 matching digits),
1949          and global_ocean.cs32x15.icedyn (only 11 matching digits)
1950      Also update output_adm of exp. lab_sea (all 4) and offline_exf_seaice.
1951    o adjoint of exch-1:
1952     - pass high-level EXCH S/R through TAF (eesupp/src/exch_ad_diff.list)
1953       (note: was already like this when using EXCH-2) and remove flow dir
1954       and hand-written AD version of high-level EXCH S/R (pkg/autodiff);
1955     - provide flow-dir for low-level exch1 S/R (eesupp/src/exch1_ad.flow);
1956     - update pkg/exch2 diff list.
1957    
1958    checkpoint62g (2010/05/19)
1959    o eesupp/src (exch-1):
1960     - split exch_rx.F into Forward S/R (exch1_rx.F) and Adjoint S/R (exch1_rx_ad.F)
1961       and remove argument "simulationMode"; same thing for all exch_*rx_cube.F
1962       (renamed to exch1_*rx_cube.F).
1963     - change accordingly exch_*_rx.template and AD version in pkg/autodiff
1964       to call new exch1 S/R ; update Makefile and .cvsignore.
1965     - replace call to exch2_xy_rx S/R with exch2_*3d_rx(myNz=1) (will remove
1966       exch2_xy_rx later)
1967      Note: after updating your code, need to run "make clean" in eesupp/src
1968    o test experiment bottom_ctrl_5x5:
1969       new output_adm.txt with fewer grdchk & less monitor output.
1970    o model/src:
1971      remove the call to ini_cori in initialise_varia.F (just keep the usual one
1972       in initialise_fixed.F). More consistent with coriolis & horizontal grid
1973       beeing treated in the same way (ini_grid is not called a 2nd time).
1974    o pkg/exf:
1975      - rewrite exf_bulk_largeyeager04.F for better vectorization, changes
1976      global_ocean.cs32x15/input.icedyn (11 digits of agreement), updated
1977      - fix adjoint (used worked for ALLOW_ATM_WIND defined, works for this now)
1978      - cosmetic changes to exf_bulkformulae.F to make it look more like
1979        exf_bulk_largeyeager04.F
1980    o eesupp/src (exch-1):
1981      - Fix AD EXCH code for 2-D domain special cases (Nx=1 or Ny=1).
1982      - Separate buffer filling and MPI sending: allow EXCH-1 to work for local
1983        array (non-shared) when using MPI+MTH. Also reduces number of BARRIER
1984        (even without using MPI).
1985      - Message mode: move RecvAck setting (indicator of buffer being ready)
1986        from send_put to recv_get S/R (was useless before, but not sure if
1987        it's much more useful now);
1988      - Switch the order of sync: MPI-proc 1rst and then threads;
1989      - take out spin-waiting code (#undef EXCH_USE_SPINNING), use BARRIER instead.
1990      - fix AD code for communication mode ='get' (but not used).
1991    o model/src:
1992      initialise dPhiHydX,dPhiHydY inside calc_grad_phi_hyd.F (so that TAF does
1993      not drop it in S/R mddynamics, producing NaN in hs94.1x64x5 AD-test exp).
1994    o utils/matlab/rdmnc.m: adapt to be able to use the generic matlab netcdf API
1995    o pkg/ctrl: require a specific set of control variables and exf-flags for
1996      adjoint of seaice (stop in ctrl_check.F if conditions are not satisfied)
1997    o model/src:
1998     a) 1rst version of a new driver S/R to turn-off output freq and flags after the
1999       1rst forward sweep, to avoid over-writing output files during recomputations
2000       recomputations (& grdchk); called from cost_final.F (& ctrl_init_ctrlvar.F ?)
2001     b) 2nd version:
2002      - add specific pkg S/R for seaice & ptracers (called from S/R TURNOFF_MODEL_IO);
2003      - switch-off more output flags (exf_monFreq, chkPtFreq, dumpInitAndLast,
2004         writePickupAtEnd) + seaice & ptracers output;
2005      - do not switch off MNC flags (otherwise, won't get admonitor netcdf file)
2006    o model/src:
2007      - new S/R rotate_uv2en_rl (..._rs) that rotates vector fields.
2008    o pkg/exch2:
2009      - remove "simulationMode" from arg. list of S/R EXCH2_RX1,2_CUBE ;
2010      - add argument "signOption" to EXCH2_RX1_CUBE (will be needed for SM exch).
2011    o pkg/autodiff & exch2:
2012      process exch_uv_agrid_3d_rx.f & exch2_uv_agrid_3d_rx.f through TAF
2013      (for now, only if ALLOW_EXCH2 is defined).
2014    o pkg/autodiff:
2015      - include PACKAGES_CONFIG.h in exch*ad.flow & exch*ad.F
2016        (not supposed to be in CPP_OPTIONS.h) to get ALLOW_EXCH2 defined correctly.
2017       + clean-up comments (_RS is not always real*4)
2018      - fix bug in ADEXCH_UV_3D_RX (without EXCH2, was calling the forward exch S/R)
2019      - add a stop in ADEXCH_UV_AGRID_3D_RX if trying to use it with EXCH2:
2020        was calling a forward exch2, which is wrong ; used in SEAICE & EXF pkgs.
2021    o testreport (AD-tests):
2022      no longer link files from dir "../input" (1rst link files from
2023      "../input_ad.[xx]" if secondary test "xx" and then from "../input_ad")
2024    
2025    checkpoint62f (2010/04/29)
2026    o model/src/the_main_loop.F:
2027      adjust store directives for seaice evp and multicategory according to
2028      pkg/ecco/the_main_loop.F
2029    o adjoint:
2030      global_sum_ad was incomplete (noted many times by many people ;)
2031      nice description by Jean U. as follows:
2032      * allreduce(var) in global_sum.F can be interpreted as
2033        reduce(sum) followed by broadcast of sum.
2034      * The adjoint of that is
2035        sum(adjoint) followed by broadcast(summed adjoint value)
2036        or in other words, allreduce(sum, adjoint vars)
2037      We were missing the sum(adjoint)!
2038      Benign, except(!) for "global" scalars appearing in tile loops (bi,bj)
2039      (noted by J.M. Campin, e.g., in cost_ssh_mean, variable offset).
2040      The fix should produce 16-digit accuracy between
2041      single-CPU multi-tile (e.g. nSx=2, nPx=1) and
2042      multi-CPU single-tile (e.g. nSx=1, nPx-2)
2043      We'll probably change this yet again shortly
2044    o eesupp/src:
2045      - fix global_sum_r4 (wrong from previous modif in Jun 2009; ever used ?)
2046    o pkg/icefront
2047      - ALLOW_SUBGLACIAL_RUNOFF option adds capability for time-evolving
2048        specification of addmass array based on a 2D field, which is added
2049        at bottommost wet level at each horizontal location.
2050    o model/src:
2051     horizontal grid initialisation (other than curvilinear): add code for Exch2 IO
2052     layout; (not always compatible with delX,delY setting; commented out for now).
2053    o pkg/exch2:
2054     change tile to processor setting (case nSy*nPy > 1): allows default model mapping
2055     (myX and myYGlobalLow) to be used for simple (1 facet, no blank tile) config.
2056    
2057    checkpoint62e (2010/04/15)
2058    o pkg/obcs:
2059      - fix wrong index in OBCS_SPONGE_V for Eastern-OB (reported by David Hebert).
2060    o pkg/dic:
2061      -fix bug in fe_chem.F for multi-tile (nSx*nSy > 1) set-up;
2062        (note: not presently tested in any forward verification exp.)
2063       update tutorial_global_oce_biogeo AD output file.
2064    o pkg/exf:
2065      - account for the variation of albedo as a function of zenith angle
2066        by defining ALLOW_ZENITHANGLE in EXF_OPTIONS.h
2067    o build_options:
2068     - rename "linux_ia64_ifort+mpi_ice_nas" to "linux_amd64_ifort+mpi_ice_nas"
2069    o pkg/dic:
2070      change DIC atmos-CO2 box (method 3, dic_int1=3) initialisation & restart:
2071      - use binary pickup file for restart;
2072      - initialise atmos-CO2 box from dic_pCO2 parameter;
2073      - fix multi-threaded.
2074    o pkg/rbcs:
2075     - clean-up RBCS code: add RBCS_OPTIONS.h file ; fix multi-threaded ;
2076       change (+ fix IO calls) type of array RBC_mask from _RL to _RS.
2077     - add RBCS to exp4 passive tracer 01 (rbcs was previously untested)
2078       and update output.txt
2079    o pkg/kpp:
2080     - add diagnostics for KPP non-local flux of Temp, Salinity and pTracers;
2081     - change diagnostic of KPP non-local term: output average of KPPghat*KPPdiffKzS
2082       (= ratio of KPP non-local (salt) flux relative to surface-flux) when
2083       using pkg/timeave & pkg/diagnostics (diag 'KPPghatK' replaces 'KPPghat ');
2084     - change pkg/offline to read-in average KPPghat*KPPdiffKzS from file
2085       KPP_ghatKFile (instead of the average of KPPghat from file KPP_ghatFile).
2086    o pkg/offline:
2087      fix bug in S/R OFFLINE_FIELDS_LOAD regarding surfaceForcing conversion factor
2088      (bug was added in version 1.10 on 2007-08-23).
2089    o pkg/offline:
2090      - no need to specify periodicExternalForcing, etc ... to use offline pack
2091      - offline input files no longer just single prec --> parameter offlineLoadPrec
2092    o verification/lab_sea:
2093      change AD test to multi-tile setup and update all 4 AD output.
2094      NOTE: while cost function values remain very similar,
2095      gradients are very different, although gradient checks are self-consistent
2096      Should try to get to the bottom of this (cost function summation order?)
2097    o pkg/dic:
2098      in carbon_chem.F, replace log10 (AUTODIFF) with explicit form to avoid
2099      a weakness of TAF that drops part of double precision in log10 derivative.
2100      <= changes removed since problem has been fixed in current TAF version 1.9.71
2101      update AD output of exp. tutorial_dic_adjoffline & tutorial_global_oce_biogeo.
2102    o pkg/ecco:
2103      add missing "_d 0" in cost_readers.F, cost_readtopex.F & cost_readtopexmean.F
2104      update all 4 lab_sea AD output.
2105    
2106    checkpoint62d (2010/03/22)
2107    o build_options:
2108      remove '-r8' (and '-i4') from linux_*pgf and linux_*ifort optfiles.
2109    o remove unbalanced quote (single or double) in commented line of source code
2110      (may cause some warning with some preprocessor/makedepend versions).
2111    o pkg/seaice:
2112      fix seaice_model.F for adjoint (gael) and update AD results of experiments
2113       lab_sea (std + evp + noseaicedyn) and offline_exf_seaice.
2114    o testreport:
2115      add option '-runonly' (short: '-ro') to just do the run part (without make).
2116    o eesupp: remove JAM communication code (obsolete).
2117    o add option to genmake2 & testreport to switch "_RS" type to "real*4"
2118      (if allowed in CPP_EEOPTIONS.h); update default CPP_EEOPTIONS.h and return
2119      to default CPP_EEOPTIONS.h for exp. inverted_barometer & solid-body.cs-32x32x1
2120      (update also the output).
2121    
2122    checkpoint62c (2010/03/02)
2123    o tools/build_options :
2124       move (some) old optfiles from build_options/ to build_options/unsupported/
2125    o model/src and pkg/exf
2126       surface relaxation -- separating data and data.exf options
2127       The point is to ensure that we specify the surface relaxation
2128       either in data or in data.exf (but not half and half) and to
2129       avoid an accidental relaxation to 0 (which happened if a time
2130       scale was specified but the file name was left empty)
2131    o model/src model/inc and pkg/mom_common
2132       ALLOW_3D_VISCAH/ALLOW_3D_VISCA4 => 3D specification of Viscosity
2133       => addition to the viscosity field as computed by others schemes
2134    o tools/build_options:
2135      - rename "_generic_mpi" -> "+mpi_generic" (like other "+mpi" optfile)
2136        but keep the former optfile for few weeks for smooth transition
2137    o pkg/ecco
2138      - allow user defined cost function contributions
2139         CPP: ALLOW_USERCOST_CONTRIBUTION
2140         USAGE: compute contributions in cost_usercost_all.F
2141      - note: this is identical to what ALLOW_GENCOST_CONTRIBUTION once was.
2142          the two options are complementary.
2143    o pkg/smooth
2144      - migration from contrib to the main repository
2145    
2146    checkpoint62b (2010/01/26)
2147    o pkg/monitor:
2148      - change back mon_printstats_rl.F & mon_stats_rl.F and add a stop
2149        (in case someone forgot to update customized pieces of code)
2150    o nonHydrostatic:
2151      - add Non-hydrostatic free-surface form (selectNHfreeSurf=1)(not fully tested);
2152      - add a simple 2-D experiment (short_surf_wave) to test it.
2153    o pkg/icefront:
2154       adding the shell of, and the hooks to, a new package that
2155       will model melting and freezing of vertical glacier ice fronts
2156    o momentum:
2157      add diagnostics of momentum tendency from Hydrostatic pressure gradient
2158       (without surf.pressure term: would need a 2nd filling since implicit term).
2159    o add 3 "_d 0"s so that fizhi compiles with xlf on iblade, and replace
2160      two " &end" by " &" (in fizhi-cs-*) because S/R NML_SET_TERMINATOR
2161      cannot deal with the former
2162    o cleaning:
2163      - remove all (except OpenAD) old TLM output from results_ad dirs.
2164      - remove unused S/R (MDSWRITEMETA, DIAGNOSTICS_ADD2LIST, old DFILE IO S/R)
2165      - comment out maskH definition (replaced by maskInC)
2166    o pkg/monitor:
2167      - change mon_printstats_rl.F & mon_stats_rl.F (were similar to mon_writestats_rl
2168        & mon_calc_stats_rl) to be the RL equivalent of mon_printstats_rs & mon_stats_rs.
2169    
2170    checkpoint62a (2010/01/15)
2171    o model/src:
2172      - bottom pressure diagnostic: correct for r* (when nonlinFreeSurf >= 4)
2173    o pkg/diagnostics:
2174      - add optional level number diagnostics (i.e., level number to be define
2175        explictly with S/R DIAGNOSTICS_SETKLEV) with parser-code(10)="X".
2176      - strictly check for valid parser-code(10) ;
2177      - check if adding diag to the list from the right place.
2178    o pkg/longstep:
2179      - change parameters and fix tracer conservation with rstar/nonlinear free surface
2180    o diagnostics:
2181     - in all pkgs, replace remaining calls to old S/R DIAGNOSTICS_ADD2LIST with newer
2182       S/R DIAGNOSTICS_ADDTOLIST ; fix seaice VICE diagnostics.
2183    o pkg/diagnostics:
2184     - Add option for writing vertical integral (sum of selected levels) of an output
2185        field instead of writing output field levels. Activate this option on a per
2186        output-file basis, by setting the 2nd character of fileflag to 'I'.
2187     - Add field-specific information relative to level integral in 3rd postion
2188        of parser diagnostics code (gdiag): " "=cumulate levels, "R"=integrate
2189        vertically (x level-thickness x hFac), "r"=same but without hFac.
2190    o do_the_model_io:
2191      - pass end-of-model-run flag as argument, from forward_step to diagnostics_write:
2192        in case useSIGREG, will write (averaged) diagnostics (if dumpAtLast) before
2193        writing pickups and stopping.
2194    o pkg/diagnostics (for now, only with mdsio):
2195      - write time information to meta file (and modify accordingly rdmds.m) :
2196        time-averaged diagnostics output: write starting and ending time of the
2197        time-averaging interval ; snap-shot diagnostics output remains unchanged;
2198    o pkg/timeave:
2199      - S/R TIMEAVE_NORMALIZ: change size of cumulated-time array (was previously
2200        always Nr), now assumed to be equal to number of levels of averaged field;
2201        only used for DIC_COST monthly mean arrays: this fixes dic_aver_final.F
2202    o pkg/sbo:
2203      - fix ocean bottom pressure global-average & 2-D time-ave output (was
2204        neither initialised nor filled).
2205      - add starting iteration in suffix of global-average output file
2206        (to avoid over-writing the file after a restart)
2207      - use standard MDSIO pkg S/R instead of SBO_WRITEVECTOR (fix byte-swap Pb).
2208    o time-average:
2209      - use simple cumulative-time array (no k index) in all pkgs: {PKG}_timeAve(bi,bj)
2210        (pkgs: aim_v23, bulk_force, dic, gmredi, kpp, land, ocn_compon_interf,
2211         ggl90, my82, opps, pp81, ptracers, sbo, seaice, shelfice, thsice)
2212        this fix DIC_COST cumulative-time array (previously: bi,bj,k)
2213      - fix 1rst call (nIter0) snap-shot output and accumulation (pkg/shelfice)
2214      - fix missing accumulation for pkg/opps.
2215      - cumulate fields only if doing time-ave output ({PKG}_taveFreq > 0)
2216         (pkgs: ptracers, kpp, ocn_compon_interf, ggl90, my82, pp81);
2217      - fix initialisation of time-ave vars and do only full time-step increment
2218        (i.e.: no first & last "half time-step") (pkgs: ggl90, my82, opps, pp81);
2219    o pkg/layers:
2220      - use standard RW pkg S/R to write the output
2221        and remove local write_fld version (which had a problem).
2222      - use simple cumulative-time array (no level index) to fix time-ave S/R calls.
2223      - fix LAYERS_CALC argument list.
2224    o pkg/timeave:
2225      - store cumulative-time in a simple tiled array (drop the level index)
2226      - add new S/R (TIMEAVE_NORMALIZE) which uses simple cumulative-time array.
2227    o pkg/ocn,aim_compon_interf
2228      - changes for multi-threaded coupled run. (tested with ifort-11 on danton)
2229    
2230    checkpoint62  (2009/12/23)
2231    o switch on useOBCSbalance in tutorial_plume_on_slope exp. and update output.
2232        (was not previously tested in any other exp.)
2233    o pkg/monitor:
2234      - clean-up _RL/_RS version: add specific S/R for statistics with mask & volume:
2235        mon_writestats_rl/s,F mon_calc_stats_rl/s.F ; will keep the old one
2236        (mon_printstats_rl/s,F mon_stats_rl/s.F) just for bare statistics.
2237      - use hFac & 2-D mask (instead of 3-D mask + hFac in previous mon_stats_rl.F).
2238      - change del2 calculation.
2239      - use interior masks (instead of maskH, <- to be remove).
2240      - shorter monitor suffix for forcing stats ("forcing" instead of "extforcing").
2241    o mask & obcs:
2242      - define 2-D "interior" masks (i.e., zero beyond OB) at 3 locations (C, W & S).
2243      - move global area computation from ini_masks_etc.F to ini_linear_phisurf.F
2244        (called after packages_init_fixed)
2245    o pkg/obcs:
2246      - move bi,bj loops into obcs_calc, so obcs_prescribe_read is called only once.
2247        Fixes bug in obcs+exf with nSx*nSy.GT.1
2248      - fix multi-tile handling in obcs balance code
2249    o nonHydrostatic:
2250      - Implement AB-3 for non-hydrostatic vertical momentum ;
2251        (change ordering of var. stored in pickup file when using NH)
2252      - move NH code from solve_for_pressure.F to 2 new S/R: PRE_CG3D & POST_CG3D.
2253      - add 2-D field to store Hydrostatic Surface Pressure adjusment from cg3d_x
2254        (in prep. for new NH free surface form).
2255    o pkg/obcs:
2256      add files & OB-variables for wVel (Non-Hydrostatic) with useOBCSprescribe
2257    o model/src:
2258      fix 2-D solver initialisation for deep-atmosphere (p-coord) with topography
2259    
2260    checkpoint61z (2009/12/01)
2261    o nonHydrostatic:
2262      Fix missing vertical flux of vert. momentum near surface (k=1). This fixes
2263        a spurious source of energy in simple baroclinic adjusment test case.
2264      Update all non-hydrostatic exp output.
2265    o model/src (3-d solver):
2266      Change again 3-D solver free-surface RHS term when exactConserv=T:
2267        simpler, consistent with exactConserv, and works with implicDiv2Dflow < 1
2268        (which was not the case with previous formulation).
2269      To recover previous version, just reset "oldFreeSurfTerm" to previous value.
2270      Affects results of exp. global_ocean.cs32x15.viscA4 & hs94.cs-32x32x5.impIGW.
2271    o nonHydrostatic:
2272      - compatible with implicDiv2Dflow < 1 ; + implement implicit factor
2273        for Non-Hydrostatic pressure gradient (similar to implicSurfPress).
2274      - change 3-D solver to work with r* (for now, only with linear free-surf.)
2275      - add few debug diagnostics (cg3d_x, residual)
2276    o model/src:
2277      fix missing EmPmR in 3-D solver RHS (was in cg2d_b but missing in cg3d_b).
2278        update output of exp. global_ocean.cs32x15.viscA4
2279    o update output of exp. global_ocean.cs32x15.icedyn after removing
2280      #define SEAICE_OLD_AND_BAD_DISCRETIZATION from SEAICE_OPTIONS.h
2281    o add entry points for Gianmaria's Nesting pkgs (from Contrib/nesting_sannino)
2282    o mnc: add horizontal grid coordinates (XC,YC) and (XG,YG) to netcdf output
2283      for complex grids, for now only to "state", "adstate", "adexf", "adseaice"
2284    o model: add Christopher Wolfe's implemetation of the single reduction cg2d
2285      (d'Azevedo, Eijkhout, and Romine, 1999) with CPP-flag ALLOW_SRCG and
2286      runtime flag useSRCGSolver. Modify verification experiment global_with_exf
2287      to test this code
2288    o pkg/cd_code:
2289      Change defaut D-grid time-stepping to get the same for D-grid momentum as for
2290       C-grid momentum. D-grid velocity used to be stepped forward in time with
2291       Adams-Bashforth only on surface pressure term. Tests show that using AB on
2292       D-grid coriolis term improves stability (as expected from CD-scheme paper).
2293      To reproduce old results, add 2 options (in CD_CODE_OPTIONS.h).
2294      Update results of exp: global_with_exf (x2), ideal_2D_oce, isomip (x2),
2295       lab_sea (3 Fwd +3 AD), natl_box (x2), tutorial_global_oce_biogeo (Fwd+AD),
2296       tutorial_global_oce_latlon, tutorial_global_oce_optim & tutorial_tracer_adjsens.
2297      Keep old results by adding CD_CODE_OPTIONS.h in exp: cfc_example, exp2,
2298           global_ocean.90x40x15(+AD), global_ocean_ebm(+AD) and OpenAD.
2299    o pkg/obcs:
2300     - fix bug in initialisation (broken since Oct 1rst modification)
2301       for useOBCSprescribe without useEXF.
2302    
2303    checkpoint61y (2009/11/15)
2304    o pkg/seaice
2305     - change (once again) the discretization for the evp solver: rather than
2306       squaring the averages of strain rates, average the squares to give
2307       a better approximation to VP behavior (in simple test); this breaks
2308       verification experiments that use EVP (lab_sea and lab_sea.hb87)
2309        --> update outputs
2310    o add CPP-flag (in mom_calc_visc.F) and TAF directive (in gmredi_slope_limit)
2311      to improve vectorization of adjoint code on TARGET_NEC_SX
2312    o verification/vermix:
2313      - change vermix to a more "classical" 1d column with high vertical
2314        resolution, seasonal heat flux forcing and constant wind forcing
2315        --> update outputs
2316    o pkg/seaice
2317     - fix diagnostics of principal stress components for EVP
2318     - add optional diagnostics of non-linear convergence for LSOR solver
2319     - make maximum zeta a runtime parameter
2320    o model/src (3-d solver):
2321      Undo modif from Dec 12, 2005 (solve_for_pressure.F cvs version v.49),
2322       which consisted in removing the Surf. Non-Hydrostatic pressure from the
2323       whole column and adding it to Eta (inspired from Casualli, 1999):
2324       Only affects 3-D solver initial guess and only if using ExactConserv,
2325       but tests did show a degradation of solver convergence. For this reason,
2326       decide to disable this piece of code.
2327       to recover previous version, just set zeroPsNH = exactConserv (line 78).
2328      Update output of exp. global_ocean.cs32x15.viscA4 & hs94.cs-32x32x5.impIGW
2329    o pkg/ggl90:
2330     - fix previous modif (unfortunatly has not been documented here).
2331    o pkg/seaice/autodiff:
2332     - add CPP flag to include clipping of zeta in EVP code;
2333       although clipping of zeta is not necessary for EVP and not recommended
2334       it was done by default, now clipping is disabled by default
2335     - modify computation and store zetaC/Z in seaice_evp for TAF
2336     - add CPP-flag SEAICE_ALLOW_CLIPVELS (undefined by default)
2337     - change seaice_calc_viscosities/strainrates for better
2338       vectorization after AD by TAF
2339     - rearrange common blocks in SEAICE.h once again for easier dumps of
2340       adjoint output, adjust adcommon.h and g_common.h
2341     - change flux form of default advection scheme for better vectorization
2342       of adjoint code
2343     - modify lab_sea/input.lsr to test the flux form of default advection
2344       scheme
2345    o autodiff: fix seaice fields in g_common.h (left over from 3 to 1 level
2346      transition in checkpoint61r)
2347    
2348    checkpoint61x (2009/10/19)
2349    o adjoint: adding two new verification experiments
2350      * tutorial_global_biogeo: an online dic sensitivity experiment
2351        (work with G. Forget)
2352      * tutorial_dic_adjoffline: an offline dic sensitivity experiment
2353        (an update of the Dutkiewicz et al., 2006 paper)
2354      Both use the same CO2FLUX cost function, but different controls
2355      Gradient checks look good, but some recomp. could still be traightened out
2356      Should add xx_dic control variable to test at some point
2357    o model/src:
2358      add run-time parameters to check and/or mask initial Temp & Salt
2359    o pkg/ptracers:
2360      apply zonal filter (if used) to all passive tracers
2361    
2362    checkpoint61w (2009/10/12)
2363    o adjoint:
2364      * update and finish work on adjoint of dic package (G. Forget)
2365      * start adjoint of offline package
2366      * bug fix for cube-sphere TLM code (active_file_g.F)
2367    o tutorial_global_oce_optim:
2368      now tested with 4 tiles (change data.grdchk and update output_adm.txt)
2369      and add SIZE.h_mpi for MPI testing
2370    o pkg autodiff
2371     - fix bug in autodiff_restore
2372     - make genmake2 remove comments and empty lines from ad_input_code.f in
2373       order to reduce file size (new script file remove_comments_sed)
2374    o allows to specify vertical profile of vertical viscosity (viscArNr)
2375    o pkg autodiff
2376      autodiff_ini_model_io: comment out writing of grid information to netcdf
2377      files, because at this time the grid fields are a bunch of zeros
2378      (this is analogous to ini_mnc_vars.F)
2379    o pkg seaice/autodiff:
2380     left-over from removing the 3-time-level fields:
2381     - small rearrangement of common blocks (SEAICE.h)
2382     - fix field declaration in order to get meaningful output in
2383       adseaice.*.nc (adcommon.h)
2384    o pkg obcs:
2385     - go through NH code only if nonHydrostatic=T
2386     - fix restart for Orlanski (Hydrostatic; still to fix NH+Orlanski restart)
2387     - move call to OBCS_CALC before SEAICE_MODEL which needs seaice-obc fields
2388       => Update output of experiment seaice_obcs
2389     - useOBCSbalance: code is wrong with multi-tile / proc: add a stop.
2390     - fix NH+Orlanski restart (add wvel OBC value in pickup file)
2391     - fix restart for useOBCSprescribe + useEXF
2392    o pkg ctrl
2393     - make obcs as control parameter work also with useSingleCPUio
2394     - replace a few sny and snx by Ny and Nx to be consistent with
2395       ctrl_set_globfld_x/yz.F
2396    o pkg seaice
2397     - re-introduce global field frWtrAtm for the case of
2398       ALLOW_MEAN_SFLUX_COST_CONTRIBUTION defined (SEAICE.h, seaice_growth.F)
2399     - catch the case of an empty filename in seaice_cost_init_fixed.F
2400    o pkg ecco:
2401     - small bug fixes in the_main_loop
2402      . fix order of monitor arguments
2403      . change SEAICE_MULTILEVEL to SEAICE_MULTICATEGORY
2404      . move include DYNVARS.h up outside the ALLOW_AUTODIFF_TAMC block so
2405        that ALLOW_ECCO_FORWARD_RUN works with NONLIN_FRSURF
2406     - replace cos(yc*deg2rad) by _rA in cost_mean_heat/saltflux.F, fix the
2407       imbalance diagnostics for wmean_h/sflux = 0
2408     - add actual values to f_obcsn/s/w/e in ecco_cost_final.F
2409     - catch the case of empty filenames in ecco_cost_init_fixed.F
2410       and ecco_readparms.F
2411     - fix the logic of wsalt=0.and.wsalt2=0 to wsalt=0.or.wsalt2=0 (and theta)
2412       to make this statement meaningfull in ecco_cost_weights.F
2413    o pkg zonal_filt:
2414      - change ZONAL_FILTER S/R interface (allows to filter 2-D fields)
2415      - when using rStar, filter uVel*hFacW instead of uVel
2416       (tested without topography: fix a Pb of growing instability with NLFS)
2417    o pkg/aim/thsice:
2418     -Add capacity to read a Q-Flux to be applied in slab-mixed layer thsice_slab_ocean.F
2419      (works as SST restoring)
2420    o pkg/thsice:
2421     -add specific parameter for salt restoring in slab mixed-layer
2422       (by default equal to the temperature restoring)
2423    
2424    checkpoint61v (2009/09/21)
2425    o pkg/kpp:
2426     -add double diffusive contributions as a hack, turned off by default
2427      for now, and the code can be excluded with a CPP-flag
2428      EXCLUDE_KPP_DOUBLEDIFF just as EXCLUDE_KPP_SHEAR_MIX
2429     -add a verification experiments to "vermix" to test this code
2430    o pkg/mom_common:
2431      Move computation of length scales to mom_init_fixed.F (avoid recomputation
2432      at each time-steps*levels).
2433    o pkg/layers:
2434      Created a new package for computing volume fluxes in temperature or
2435      [not yet implemented] density layers, e.g. for calculating residual
2436      overturning circulations.
2437    o pkg/diagnostics:
2438      implement a RS type version for the set of DIAGNOSTICS-FILL subroutines
2439    o fix few RS/RL type mismatch (check with ifort 11.1 "-warn all" option)
2440    o pkg/mdsio (& pkg/rw): rework high level S/R interface:
2441      To avoid mixing type (RS/RL) of input/output array argument,
2442      replace single mixed-type array with a pair from each type (RS/RL).
2443    o setting pickupSuff force to start from a pickup (even if nIter0=0): this
2444      is now implemented for all pkgs (previously only done for the main pickup)
2445    
2446    checkpoint61u (2009/08/25)
2447    o pkg/obcs:
2448      - change OB?eta from _RS to _RL and put them into a separate commen block
2449      - add code to read OB?eta from a file via obcs_prescribe_read: the code
2450        compiles and does not destroy any other experiments, the data is read
2451        properly, but the code is not tested in actual applications
2452    o ini_mnc_vars.F: if available (ALLOW_CAL), use startTime_1 and 2 to
2453      create a meaningful unit attribute for the time coordinate variable
2454    o pkg/ebm: add plenty of missing "_d 0" ;
2455       update results of experiment global_ocean_ebm (fwd + adjoint tests)
2456      Notes: several pieces of code only works for (very) specific set up
2457       (domain size, lat range, etc ...); should be documented & stop if one
2458       of those assumptions is not meet.
2459    o pkg/seaice: add missing "_d 0" in HSNOW initialisation
2460       update results of experiments: lab_sea (3 fwd tests + 2 adjoint tests)
2461          and offline_exf_seaice (seaicetd + adjoint).
2462    o add missing "_d 0" in ShortWave flux penetration (S/R SWFRAC):
2463       update results of experiments: lab_sea (4 fwd tests + 3 adjoint),
2464        seaice_obcs, global_ocean.cs32x15 (icedyn & thsice) and natl_box (x2).
2465    o few changes to pass when compiling with strick checking of arguments
2466       across S/R (allow to find few bugs in S/R calls).
2467    o pkg/seaice:
2468     - seaice_evp: move if-statement out of loop (TEM) at the cost of 11 new
2469       2d-fields, for slightly better performance
2470    
2471    checkpoint61t (2009/07/22)
2472    o pkg/seaice:
2473     - remove unused variables in seaice_evp
2474     - reduce number of SQRT in seaice_evp and seaice_calc_viscosities
2475    o eeset_parms.F, open_copy_data_file.F & ini_parms.F:
2476       named file replacing SCRATCH files (for TARGET_BGL & TARGET_CRAYXT):
2477       each processor opens a different file (a fix from Matt).
2478    o cg2d:
2479       use simple EXCH (overlap size = 1 and ignore corners), like in cg3d.F :
2480       this reduces number of EXCH calls by 2 when using exch2.
2481       For now, keep previous size array for gc2d_nsa.F to avoid Pb with store
2482       directives and missing simple EXCH (exch_s3d_rx) adjoint code.
2483    o pkg/thsice:
2484       add code for Near Infra-Red albedo (from Jeff)
2485       (turned on with run-time flag: thSIce_calc_albNIR, in data.ice).
2486    o ini_model_io:
2487       move (from packages_readparms.F & initialise_fixed.F) to ini_model_io.F
2488       MNC & MONITOR initialisation calls; move MNC calls from {pkg}_readparms.F
2489       to {pkg}_init_fixed.F for {pkg}= kpp, seaice & shelfice.
2490    
2491    checkpoint61s (2009/06/30)
2492    o pkg/exch2 (exch2_rxN_cube*):
2493       remove last BARRIER (no need to synchronise after getting data from shared
2494       buffer (get) as long as any change to buffer (put,recv) is between BARRIER)
2495    o change tiling of natl_box (from 2 to 4 tiles) to get it tested with MPI+MTH
2496      and generate new output (for the 2 tests) using default rotationPeriod.
2497    o pkg/exch2:
2498      - always call exch2_*_cube, not exch-1 anymore, if useCubedSphereExchange=F
2499        (was already the case with AUTODIFF_EXCH2 defined)
2500      - add bj in exch2 arrays and S/R.
2501      - can now use pkg/exch2 for regular (non CS) set-up; switch test experiment
2502        MLAdjust to exch2 (identical results except with MPI -> truncation diff);
2503    o add pkg/longstep for ptracer timestep a multiple of U/V/T/S timestep
2504      - adds deltaT argument to the subroutines TIMESTEP_TRACER DWNSLP_APPLY
2505        GAD_ADVECTION GAD_CALC_RHS GAD_IMPLICIT_R GAD_SOM_ADVECT
2506      - verification experiment natl_box.longstep
2507    o build_options: ifort+mpi_aces optfile (following Constantinos advise):
2508      allow different versions of ifort (8 or 9) and different versions
2509       of mpi (mpich or mpich2) to be used with the same optfile.
2510      requires to load a netcdf module and set MPI_INC_DIR (see comments inside
2511       optfile). Change testing scripts (example_scripts/ACESgrid) accordingly.
2512    o pkg/seaice:
2513      fix previous modif (3-level field removed) for old-pickup reading
2514    
2515    checkpoint61r (2009/06/25)
2516    o pkg/seaice:
2517     - clean up the 3-time levels of UICE,VICE,HEFF,AREA in three steps:
2518      1. introduce fields for time step (N-1)
2519      2. do not use levels 2 and 3 anymore (but keep them)
2520      3. replace 3D versions of UICE,VICE,HEFF,AREA by 2D versions. This
2521         includes changes to pkg/thsice/thsice_get_velocity.F,
2522         model/src/external_forcing_surf.F, pkg/obcs/obcs_apply_seaice.F, and
2523         pkg/obcs/obcs_apply_uvice.F.
2524     - completely remove code for leap-frog time stepping for second order
2525       advection
2526     - adjusted adjoint accordingly;
2527       gradient checks have improved by an order of magnitude!
2528    
2529    checkpoint61q (2009/06/22)
2530    o pkg/seaice: fix bug in free slip boundary conditons for LSOR solver
2531     - the boundary conditions along open boundaries are unclear, because the
2532       associated masks are set to zero and are thus treated as closed when
2533       applying the slip-boundary conditions.
2534     - move initialisation of grid variables from seaice_init_varia to _fixed
2535    o adding doc/diags_changes.txt
2536    o model/src:
2537      do_the_model_io: rename few pkg S/R which are called from do_the_model_io,
2538       to avoid "_diags" naming if no relation to pkg/diagnostics.
2539      ini_theta,ini_salt: fix (at least compile the code) reading from NetCDF
2540       file and only call PLOT_FIELD_XYZ if debugMode=T.
2541      remove few PLOT_FIELD_XY calls outside initialisation.
2542      remove few unnecessary BARRIER.
2543    o pkg/salt_plume: add SaltPlumeSouthernOcean to allow disabling
2544      of salt_plume package in Southern Ocean
2545    o pkg/thsice:
2546     - fix hOceMxL in overlap (needed for sea-ice advection);
2547       update output of experiment global_ocean.cs32x15.icedyn.
2548    o pkg/seaice:
2549     - make the (placeholder-)tracer IceAge a little more meaningful
2550      by avoiding ridging of age due to convergent ice flow
2551     - add diagnostics for surface temperature, atmospheric and oceanic
2552       heat flux, and atmospheric and oceanic ice growth
2553    
2554    checkpoint61p (2009/06/10)
2555    o eesupp (global_max & global_sum):
2556     - add one more element to buffer (start at index 0) for GL_MAX/SUM output;
2557     - remove starting & endding barrier (no longer needed)
2558    o pkg/mdsio, writelocal:
2559       works also in multi-threaded when LOCBIN_IO_THREAD_SAFE is undefined
2560       (remove the STOP): uses shared buffer IO to store data from all threads
2561       and then let master-thread write nThreads tiles.
2562    o pkg/mdsio (read/write field):
2563     - tiled IO done in 1 piece (all levels at a time);
2564     - new header file "MDSIO_BUFF_3D.h" with 3-D buffers.
2565     - multi-threaded: allow to read/write local (non-shared) array
2566       (was already working with singleCpuIO ; now works also without);
2567       => no longer needs barrier call after reading a file (added inside
2568       mds_read/write field).
2569     - move barrier calls outside gather/scatter_2d to mds_read/write_field
2570    o pkg/obcs/exf
2571      - exf_getffieldrec.F: add a few ". _d 0" and
2572                            add code to catch the case fldperiod = 0.  
2573      - obcs_precribe_read.F: change if statements so that they match
2574                              the variable type (_RL)
2575      - add a separate exf_iprec_obcs to exf_set_obcs (by default equal to
2576        exf_iprec) as part of namelist EXF_NML_01
2577    o pkg/mdsio:
2578      - read/write tiled (local) files: read/write 1-level tile chunk at a time
2579        (instead of segment of length sNx); expected to speed up tiled IO.
2580    o pkg/exch2:
2581      - take buffer copy from/to array out of S/R exch2_send/recv into new
2582        S/R exch2_put/get ; Exch of local variable now works with MPI+MTH
2583        (tested by removing commom block statement in SOLVE_FOR_PRESSURE.h).
2584      - ad version of send/recv no longer needed (but needs exch2_ad_put/ad_get)
2585      - simplify argument list of S/R exch2_get_uv_bounds and exch2_get_scal_bounds
2586        (which replaces exch2_get_recv_bounds & exch2_get_send_bounds) by
2587        including Topology header file (and common blocks).
2588      - implement EXCH_IGNORE_CORNERS in scalar exchange (rx1);
2589        remove 2nd exch call in exch2_s3d_rx (no longer needed).
2590      - document S/R arg. list (+ update some comments)
2591    o pkg/seaice:
2592      - added SEAICE_CLIM_AIR code, which permits modulation of surface air
2593        temperature and humidity over sea ice based on climatological values.
2594      - clean up computation of Hibler+Bryan (1987) stress coupling for the case
2595        of LSR (this change is expected to change the results slightly because now
2596        it uses slightly difference moduli from the second last LSR solution, but
2597        that is more consistent with the stress computations; this part of the code
2598        is not tested in the verification experiments)
2599      - fix diagnostics for flux of ice in case of B-grid
2600      - turn strain rates eij and press into global fields within global
2601        common block in SEAICE.h for more straighforward diagnostics
2602      - fix diagnostics for principal stress components, press, zeta, eta
2603        to give something meaning full
2604    o change tiling of global_ocean.cs32x15 (12 tiles, 32x16) and generate
2605      new output (all 4 tests) using default rotationPeriod.
2606    o pkg KPP:
2607      - add flag (LimitHblStable) to avoid limiting BL depth under stable conditions
2608      - fix vertical indices in RI_IWMIX (match between KPP grid from 0 to Nr+1
2609        and normal grid from 1 to Nr)
2610    o Fix computations of L4rdt in mom_calc_visc.F
2611    o eesupp:
2612      new S/R ALL_PROC_DIE (like EEDIE, without irrelevant threads err msg):
2613      should be called before a "stop" if we know that all process are going
2614      to stop; if one Proc does call this S/R, will hang in MPI_FINALISE.
2615    
2616    checkpoint61o (2009/05/26)
2617    o pkg/exch2: change check_depths to issue just a warning (instead of error+stop)
2618    o model/src/ini_curvilinear_grid.F:
2619       compute angleSin/CosC when they are not read from a file
2620    o pkg/seaice:
2621       add pseudo time stepping for LSOR
2622    o pkg/exch2:
2623       temporary fix for exch2_s3d_rx; update results of exp. hs94.cs-32x32x5.impIGW
2624    o pkg/seaice:
2625       Adding separate sea ice albedo, drag coefficients, and HO in Southern
2626       Ocean from those in Arctic Ocean.  See *_south in SEAICE_PARAMS.h
2627    o SingleCpuIO:
2628       fix bug put before chkp61n (May 11), when more than 2 MPI cpu are used.
2629    o pkg/seaice:
2630       put exchanged variable in (local) common block for MPI+Multi-Threads
2631       to work (necessary with exch1, and for now with exch2 too).
2632    o verification: to get more experiments tested with mpi, mth and mpi+mth,
2633      change tiling of:
2634       aim.5l_Equatorial_Channel, aim.5l_LatLon, dome, exp4, global_ocean.90x40x15,
2635       hs94.cs-32x32x5, MLAdjust, offline_exf_seaice & tutorial_plume_on_slope
2636      update output of exp:
2637       exp4, global_ocean.90x40x15(+.dwslp), MLAdjust(all 5),
2638       tutorial_plume_on_slope and hs94.cs-32x32x5 (use default rotationPeriod)
2639      + ideal_2D_ocean: use default rotation period + test Global_Sum_SINGLECPU
2640                       (note: output.txt generated on faulks using only 1 tile)
2641    o eesupp & mdsio (SingleCpuIO):
2642     - remove MISSING_TILE_IO (from MDSIO_OPTIONS.h), replaced by run-time
2643       parameter "W2_useE2ioLayOut" (read from file "data.exch2").
2644       Note: was not effective for globalFile & useSingleCpuIO=F; now fixed.
2645     - move MDSIO_SCPU.h (pkg/mdsio) to EEBUFF_SCPU.h (eesupp/inc).
2646     - fix GLOBAL_SUM_SINGLECPU when using Exch2; re-use same buffers and same
2647       gather/scatter S/R as with SingleCpuIO (=> 1 less 2D global RL array).
2648    o pkg/exch2:
2649     - new code to set-up W2-Exch2 topology (replace matlab-topology-generator):
2650       read parameter file "data.exch2" if it exists; otherwise try default regular
2651       cube without blank-tile; new header file "W2_EXCH2_SIZE.h";
2652     - update matlab-topology-generator (exch2_setup_cs6_print.m) to be compatible
2653       with new code (not to be used, just as a backup solution).
2654     - add examples (e.g., for lat-lon-cap_120) of parameter file "data.exch2"
2655       in utils/exch2/input.
2656    
2657    checkpoint61n (2009/05/12)
2658    o eesupp & mdsio (SingleCpuIO):
2659      - move mapping to global io-buffer inside gather_2d/scater_2d: this save
2660        memory (1 less 2D global RL array); skip 1 buffer copy; and only send/
2661        receive real*4 array (instead of real*8) to read/write 32.bit files.
2662        (new template for gather_2d/scater_2d, new set of S/R MDS_PASS_R4,8toRL,S
2663         and remove new mapping S/R)
2664    o pkg/mdsio: in preparation for topology-generator within pkg/exch2:
2665      - Change declaration of SingleCpuIO buffer, reduced to only 1 dim.:
2666        xyBuffer_size, which is set to W2_ioBufferSize from W2_EXCH2_PARAMS.h
2667        when using exch2. Add S/R to map global io-buffer to global model array.
2668      - uses exch2_global_Nx,y instead of exch2_domain_nxt,nyt.
2669    
2670    checkpoint61m (2009/04/29)
2671    o write_utils : change WRITE_1D_R8 to WRITE_1D_RL
2672      and add 3 other S/R for other types (R4,R8,RS).
2673      Change calls to WRITE_0D/1D_R[4,8,S,L] to match the type of argument.
2674    o eesupp/inc/CPP_EEMACROS.h (EXCH & GLOBAL_SUM/MAX macros):
2675     - ensure suffix (_R4,_R8,_RS,_RL) correspondance between macro and S/R ;
2676     - reduce number of macro definitions (keep only those which are used);
2677       can always call directly the corrresponding S/R if needed.
2678     - everywhere in the code: change macros (EXCH & GLOBAL_SUM/MAX) suffix
2679       _R4/_R8 to _RS/_RL when applied to _RS/_RL variable.
2680     Fixed wrong type of arg in:
2681       atm2d/put_ocnvars.F cheapaml/cheapaml.F ocn_compon_interf/ocn_apply_import.F
2682       ctrl/ctrl_map_ini_ecco.F seaice/seaice_do_diags.F seaice/seaice_model.F
2683     To fix: global_sum of var in common block is wrong (multi-threaded) in:
2684       dic/dic_atmos.F ebm/ebm_area_t.F ebm/ebm_zonalmean.F sbo/sbo_calc.F
2685     To fix: aim_v23/aim_do_co2.F (BARRIER & GLOBAL_SUM within bi,bj loops)
2686    o adjustment.cs-32x32x1: test "blank tiles" when compiling with mpi; 2nd
2687      "nlfs" mpi test is going to stop when checking for unconnected tile egdes.
2688    o eesupp/src: new S/R to stop everyone when 1 (or more) Proc. find an error
2689    o pkg/exch2: new S/R EXCH2_CHECK_DEPTHS to check that unconnected tile
2690      edges are closed (zero depth); might happen with "blank tiles";
2691      for now, disabled if using OBCS.
2692    o tools/gemake2: delete modifs from March 27-29 2009 (with option "-mpi":
2693      link *_mpi files from "MODS" dir) to return to a strait-forward behavior.
2694    o move read_write.F to write_utils.F ; new parameter (maxLengthPrt1D)
2695      to reduce length of 1.D array print in STDOUT.
2696    o adjustment.cs-32x32x1: changed to oceanic test with 1 continent
2697      + use 48 tiles (16x8): this will allow to test "blank tiles".
2698    o start to test MPI + multi-threaded (change testreport to skip tests
2699      where number of tiles do not match).
2700    o genmake2: add option "-omp" to turn on Open-MP ;
2701      passed to testreport (if using -mth) ; merge few (*+mth) optfiles.
2702    o pkg/exch2 (+ utils/exch2): ignore blank tiles (instead of removing them)
2703      and keep the original tile numbering. Note: compatible with old
2704      W2_EXCH2_TOPOLOGY.h & w2_e2setup.F topology files.
2705    
2706    checkpoint61l (2009/04/07)
2707    o Overlaps had been forgotten in calculating ijk keys : fixed
2708    o fix cyrus makedepend for gcc 4.4
2709    o experiment fizhi-cs-aqualev20:
2710      switching to new version of S/R GETPWHERE (#define TRY_NEW_GETPWHERE)
2711      and generate new output. Note: new output is much closer to the old
2712      one (v1.8) generated with pgf77 -O2 on Mar 14 2007 than it is from
2713      the previous one (v1.9) generated with pgf77 -O0 on Jun 13 2007.
2714    o pkg/fizhi:
2715     - change to avoid indices going deliberately over array-bounds
2716     - remove unnecessary MPI stuff
2717     - perpetual spring equinox with "#define FIZHI_USE_FIXED_DAY"
2718     - new version of S/R GETPWHERE available with #define TRY_NEW_GETPWHERE:
2719       does not go over array-bounds and therefore returns reliable output.
2720     - in fizhi_driver.F & fizhi_turb.F, fix "get_alarm" calls:
2721       this S/R has 4 output arguments, which are used inside "get_alarm";
2722       when it is called with the same variable "ndum" in place of several
2723       output arguments, this produces weird side effect inside "get_alarm"
2724      (e.g., datein=dates(n) is overwritten by timein=times(n) since both
2725       datein & timein, resp. 2nd and 3rd arg., are pointed to the same "ndum"
2726       address) and produces error.
2727    o tools/gemake2: (March 27-29 2009)
2728      with option "-mpi": link *_mpi files from "MODS" dir (this is what
2729      testreport does).
2730    o lab_sea experiment: change from 2x1 tiles to 2x2 tiles and regenerate output
2731    o pkg/seaice: fix bug in new version of S/R SEAICE_LSR.F:
2732       update lab_sea.lsr & lab_sea.salt_plume results
2733    o pkg/seaice:
2734      Major overhaul of the LSOR solver: change discretization from original
2735      finite differences to finite volume. The old routine is still in the
2736      file seaice_lsr.F and can be turned on with the CPP-flag
2737      SEAICE_OLD_AND_BAD_DISCRETIZATION
2738      Along with this change, the discretization of the strain rates is changed.
2739      The same flag turns on the old discretization in seaice_calc_strainrates.F
2740      All verification experiments with seaice are affected (except for
2741      seaice_exf_offline); global_ocean.cs32x15/input.icedyn recovers the old
2742      results by setting the above flag.
2743      Further changes involve changes in defaults:
2744      - ALLOW_FLOODING is defined and turned on by default
2745      - SEAICEadvSnow = .true. is now the default
2746      - SEAICEadvSalt = .true. is now the default
2747      - SEAICEadvAge  = .true. is now the default
2748      - SEAICE_clipVelocities  = .false. is now the default
2749                                         (as per J. Zhang's recommendation)
2750      - B-grid, and thus not tested: SEAICE_TEST_ICE_STRESS_1/EXPLICIT_SSH_SLOPE
2751        is defined, SEAICE_TEST_ICE_STRESS_1 is renamed into SEAICE_BICE_STRESS
2752      - seaice_growth: replace computation of UG by a simple copy from wspeed
2753    
2754    checkpoint61k (2009/03/18)
2755    o pkg/seaice: a few bug fixes mostly concerning the metric terms:
2756      seaice_lsr: fixed a few metric terms,
2757                  affects lab_sea.lsr, lab_sea.salt_plume, seaice_obcs
2758                  add more debugging diagnostics
2759      seaice_evp: removed superfluous many metric terms of FV discretization
2760                  of stress divergence
2761                  affects lab_sea, lab_sea.hb87
2762      seaice_ocean_stress: removed superfluous many metric terms of FV discretization
2763                  of stress divergence for non-evp solver
2764                  (this part is not tested anywhere)
2765      seaice_calc_strainrates: fixed a bug in no-slip boundary conditions,
2766                  they were effectively only half slip
2767                  affects lab_sea.hb87
2768      updated all relevant verification experiments (except lab_sea//output_adm.txt
2769        which was left over, but fails at level 7 & 6)
2770    
2771    checkpoint61j (2009/03/17)
2772    o pkg/seaice: turn a few hard wired parameters into run time parameters
2773    o pkg/seaice/exf/monitor: turn netcdf coordinate variable T into model
2774      time in seconds as promised by the usints in seaice_monitor and exf_monitor
2775    o pkg/mnc: fix the coordinate variables for multi-tile curvi-linear grids
2776      that are not cubed-sphere grids
2777    o pkg/seaice: fix a bug for the rare case of SEAICE_VECTORIZE_LSR
2778    o pkg/ctrl:
2779      fix bug in ctrl_depth_ini.F (EXCH_XYZ was applied to 2-D field xx_r_low)
2780    o non-hydrostatic (calc_gw.F):
2781      fix viscA4 on CS-grid + fix diagnostics: Wm_Diss & Wm_Advec
2782      update output of exp. global_ocean.cs32x15.viscA4
2783    o remove backward compatibility for thetaMin,phiMin
2784      (replaced by xgOrigin,ygOrigin on Jan 27, 2009)
2785    o pkg/exf: fix a serious bug in exf_set_uv.F: do a rotation of the
2786      interpolated wind field not only for curvilineargrid=.true., but also
2787      for a rotated grid (rotateGrid=.true.)
2788    o pkg/exf: add capability to bypass interpolation for runoff
2789      by setting yet another CPP-flag
2790    o eesupp/src, B-grid exchange:
2791      add simple (6 tiles, non MPI) CS exch + standard interface S/R.
2792    o autodiff
2793      new CPP option ALLOW_TAMC_SINGLEPREC_COMLEV
2794      allows to switch to single-prec common blocks;
2795      corresponding switch occurs in tamc.h, integer isbyte
2796      TAF store directivs "byte" and "kind" seem equivalent;
2797      Most tamc.h have been updated correspondingly.
2798    
2799    checkpoint61i (2009/02/13)
2800    o autodiff:
2801      fix autodiff_sore/_restore indices for obcs
2802      (spotted by I. Hoteit, M. Mazloff)
2803    o pkg/autodiff, pkg/ctrl:
2804      Add flag to reduce all tapelev I/O to single-prec.
2805      In data.ctrl set
2806        doSinglePrecTapelev = .TRUE.
2807    o model/src/ini_curvilinear_grid.F, new grid-file format without EXCH2:
2808      check in hack for SX8 compiler (for dxV, dyU); remove it afterwards.
2809    o pkg/shelfice: fix bug with SHELFICEconserve flag, prepare for
2810      real fresh water flux (not yet)
2811    o pkg/mdsio & rw:
2812     - add argument & option to S/R MDS_WRITEVEC_LOC (avoid Open/Close & write-meta)
2813     - add simple interface S/R to MDS_WRITEVEC_LOC in pkg/rw: WRITE_GLVEC_RX.
2814    o pkg/flt:
2815     - replace FLT_INIT by 3-steps standard initialization S/R: readparms,
2816       init_fixed & ini_varia.
2817     - clean-up & simplify linear interpolation S/R:
2818       move flt_bilinear.F -> flt_interp_linear.F ; add arg. myThid.
2819     - fix some indices (mainly vertical index) ; add IMPLICIT NONE.
2820     - more efficient I/O, using new options of MDS_WRITEVEC_LOC S/R.
2821     - add vert. coordinate & horiz. indices to output files.
2822     - change vertical position in initial condition, from index to depth [m].
2823     - store horizontal (decimal) indices i,j in common block (instead of coord. x,y)
2824       (easier to get to a curvilinear grid) ; delX,delY no longer used.
2825    o pkg/ggl90: a few modifications:
2826     - fix bottom boundary condition, and interpolation of KappaE
2827       near top and bottom
2828     - use same set of viscosity/diffusivity for TKE/momnetum/tracer
2829     - add smoothing option as in Blanke and Delecluse (1993) (--> ALLOW_GGL90_SMOOTH)
2830     - add a few options for mixing-length upper limit (--> mxlMaxFlag)  
2831    o rename thetaMin,phiMin -> xgOrigin,ygOrigin
2832      (maintain temporary backward compatibility, until next checkpoint)
2833    
2834    checkpoint61h (2009/01/27)
2835    o pkg/diagnostics with "periodic averaging diagnostics":
2836      fix S/R DIAGNOSTICS_COUNT ; hack diagnostics_out.F to get NetCDF output.
2837    o pkg/my82: add missing "_d 0" ; update output of exp. vermix.my82
2838    o pkg/obcs: fix loop ranges for balancing code
2839    o pkg/flt:
2840     - improve criteria for finding which tile owns a float.
2841     - fix FLT_EXCH for case without MPI ; apply cyclic BC + fix also the MPI case.
2842    o Add well-mixed CO2 box in aim_v23 (which includes changes in pkg
2843      aim_compon_interf, ocn_compon_interf, gchem, and dic to get coupling
2844      with ocean biogeo)
2845    o pkg/flt:
2846     - do some cleaning and fix the restart ;
2847     - add output.txt in flt_example/results to get this pkg tested.
2848    o genmake2: add an EXTENDED_SRC option and flag.
2849       for now, cannot be turned on on command line (only through genmake_local)
2850    o pkg/mdsio: read/write vector:
2851     - singleCpuIO: fix RL/RS in MDSWRITEVECTOR by calling new S/R MDS_BUFFERtoRL/RS
2852     - singleCpuIO=F: fix arrType & filePrec & _BYTESWAPIO in both MDSREADVECTOR
2853       & MDSWRITEVECTOR by calling new S/R MDS_RD/WR_VEC_RL/RS.
2854     - affects gradient of test-exp "bottom_ctrl_5x5" (not due to _BYTESWAPIO)
2855      (drop to 4 digits matching for grad). But this test does not look very
2856      reliable (was already failling on eddy, fc5, at 6.digits). Update output.
2857    
2858    checkpoint61g (2008/12/29)
2859    o pkg/flt:
2860      - move FLT_CPPOPTIONS.h to FLT_OPTIONS.h (standard name)
2861       + make OPTIONS file more standard.
2862      - rename S/R MDSREADVECTOR_FLT to FLT_MDSREADVECTOR (to mach src file name)
2863      - fix _BYTESWAPIO CPP-Flag
2864      - standard reading of file-parameter "data.flt"
2865      - fix argument list of S/R FLT_RESTART
2866      still need to fix _BYTESWAPIO in pkg/mdsio/mdsio_writevector.F
2867    o pkg/obcs: fix a CPP-flag, bug reported by Jeff Blundell
2868    o gather_2d.F/scatter_2d.F: suppress vectorisation on NEC SX in respond to
2869      a still unfixed compiler/optimization bug
2870    
2871    checkpoint61f (2008/11/21)
2872    o pkg/seaice, LSR solver: fix bug in GLOBAL_MAX calls ;
2873      update results of global_ocean.cs32x15.icedyn test.
2874    o move getcon.F from model/src to pkg/fizhi.
2875    o pkg/exf: add parameter for extrapolation of temp up to the surface
2876       and option to prevent negative evap (in bulk_largeyeager04 only).
2877    o Prather Advection scheme: fix tracer conservation for divergent flow
2878      (e.g., when using NonLin Free-Surface).
2879    o kpp: retire KPPmld diagnostics --> use MXLDEPTH instead
2880    o gmredi (Visbeck-variable-K):
2881     - add more parameters to Visbeck-variable-K.
2882     - use a 5 points average for dSigmaR in Visbeck-K calculation
2883       (more "homogenous": same stencil and same weights as in dSigmaH)
2884     - update output of ideal_2D_oce experiment.
2885    o fix CPP-flag REAL4_IS_SLOW, when _RS expands into real*4
2886      (#undef REAL4_IS_SLOW)
2887     - pkg/mnc/mnc_cw_cvars.F: write _RS-grid variable as netcdf-real*4
2888       coordinate variable
2889     - pkg/monitor/monitor.F: call mon_printstats_rs for _RS variables
2890       (surface forcing fields), removes some of the functionality
2891     - model/src/write_grid.F: write _RS variables as RS-netcdf variables
2892     - model/src/diags_oceanic_surf_flux.F: fix a few diagnostics, but
2893       probably not all: copy _RS surface flux fields to RL field before
2894       calling DIAGNOSTICS_FILL
2895     - model/inc/CPP_EEMACROS.h: make the _EXCH_*_RS macros expand into
2896       real*4 (CALL EXCH_*_RS) versions.
2897     - tested in 2 experiments: inverted_barometer & solid-body.cs-32x32x1
2898       (generate new output).
2899    
2900    checkpoint61e (2008/10/23)
2901    o gmredi (Visbeck-variable-K):
2902      - fix the "OLD_VISBECK_CALC" option + move the #undef to GMREDI_OPTIONS.h
2903      - change computation of Visbeck-K where Slope > Smax :        
2904        now: N*min(Slope,Smax) (similar to OLD_VISBECK_CALC with gkw91 taperFct)
2905        previously was: M*sqrt(min(Slope,Smax)) ; update ideal_2D_oce output.
2906    o bottom-drag in P-coord.: change units of bottomDragLinear & bottomDragQuadratic
2907      to be the same as with Z-coord. (i.e., m/s & no-units respectively).
2908    o calc_viscosity: fix index range (was wrong for CD-Scheme & explicit Visc)
2909    o pkg gmredi, linear & fm07 tapering: put an upper limit on Slope^2 so that Kwz
2910      does not become too large (to avoid precision problems in implicit-diffusion
2911      solver); update ideal_2D_oce output.
2912    o pkg ggl90:
2913      - in ggl90_cal.F: compute only one set of visc/diff, used to
2914        step forward TKE/T/S/momentum
2915      - default value of GGL90viscMax/GGL90diffMax larger and equal (to
2916        have Prandlt =1)
2917    o gmredi (fm07):
2918      - add lower limit on Transition layer thickness + lower limit on 1/lambda
2919      - allow to set few more params from data.gmredi
2920    o pkg ggl90:
2921          - add missing sqrt(2) factor in computation of mixing length
2922            scale in ggl90_calc.F
2923            (see Eq. (2.35) in Blanke and Delecluse, JPO, 1993)
2924    
2925    checkpoint61d (2008/09/25)
2926    o adjoint modifs
2927      - adapt to new field rhoInSitu
2928      - allow to revert from StoreDynVars2D, StoreDynVars3D
2929        to individual fields
2930        (switches AUTODIFF_USE_OLDSTORE_2D, AUTODIFF_USE_OLDSTORE_3D)
2931    o store 3-D (in-situ) density in commom block (DYNVARS.h)
2932     - save 1 rho computation.
2933     - no longer modify T & S inland when using down_slope pkg.
2934    o gad_som : allow to switch to SOM advection for T & S without corresponding
2935      pickup files (using new S/R: MDS_CHECK4FILE).
2936    o keep removing _BEGIN/_END_MASTER between MDSIO S/R call
2937      (for useSingleCpuIO to work in multi-threaded)
2938    o pkg/shelfice:
2939     - disentangle parameters: retire shelfIceFile in data/PARM05 and substitute
2940       with SHELFICEtopoFile in data.shelfice
2941     - move code for reading ice shelf topography and modifying hFacC into separate
2942       subroutines of the shelfice package
2943     - separate initialisation of "fixed" and "variable" variables
2944     - kTopC is not (yet) replaced by kSurfC, although this is possible
2945    o fix broken diagnostic SIatmFW and changed the units from m/s to kg/m^2/s
2946    o add initialisation of deepFac if using Pcoords (new S/R set_grid_factors)
2947      and rename:
2948      ini_phiref.F          --> set_ref_state.F  (+ set anelastic factors)
2949      ini_reference_state.F --> load_ref_files.F (- set anelastic factors)
2950    o change FIND_RHO_SCALAR : return rho (instead of rho - rhoConst)
2951    
2952    checkpoint61c (2008/08/30)
2953    o add option ALLOW_ADDFLUID and run-time selector "selectAddFluid"
2954      to add mass source/sink of fluid in the interior (3-D generalisation
2955      of oceanic real-fresh water flux).
2956    o pkg/monitor: fix recip_dr argument in mon_advcflw2 call (-> advcfl_W_hf_max)
2957    o vermix test experiment: switch from LINEAR EOS to MDJWF (not tested before)
2958    o new pkg: down_slope
2959      density-driven downsloping flow parameterisation (Tellus, 1999, 412-430).
2960      - presently, modify T & S inland (dwnslp_calc_rho.F).
2961        can be avoided if rho was stored in common bloc and used in calc_phi_hyd.
2962      - implementation for ocean in P-coords not tested.
2963      - add secondary test to global_ocean.90x40x15 (input.dwnslp) to check this pkg.
2964    o move kSurfC,kSurfW & kSurfS from SURFACE.h to GRID.h (next to kLowC)
2965      (to facilitate conversion of oceanic pkg to p-coordinate).
2966    o change FIND_RHO to FIND_RHO_2D :
2967      pass arguments tFld & sFld as local (tile) 2D-arrays ; +fix EOS_CHECK.
2968    o new pkg: cheapaml
2969    
2970    checkpoint61b (2008/08/05)
2971    o exch2:
2972      change index bounds in rx2_cube exchanges (new S/R: EXCH2_GET_UV_BOUNDS)
2973      - no longer depend on the order sequence (N,S,E,W).
2974      - 3rd exchange no longer needed (tested with 24 tiles).
2975      - same modif to hand-written adjoint S/R (global_ocean.cs32x15: zero diff)
2976      - exch_UV_A-grid readily available (but not yet tested).
2977      comment out 3rd exch call and remove copy of V to U at SE & NE face-corners
2978      (both are no longer needed) in exch_uv: no effect in forward run; but
2979       get truncation error differences with adjoint exch.
2980    o exch2:
2981     - change index-bounds storage (moved from target to local tile,
2982       more intuitive this way) ; rename/remove some variables.
2983     - change utils/exch2/matlab-topology-generator & code_mods accordingly.
2984    
2985    checkpoint61a (2008/07/29)
2986    o exch2/matlab-topology-generator:
2987      fix bug in index bounds for N-S internal exchange (hard to tell if this
2988      had any effect on the solution).
2989    o pkg/mnc: small fix in mnc_handle_err: make sure that length of msgbuf
2990      is exceeded
2991    o testreport: modify syntax of awk, so that it works also with
2992      awk, and not only with nawk and gawk
2993    
2994    checkpoint61 (2008/06/24)
2995    o autodiff
2996      Change default for TAF usage by removing argument '-nonew_arg'
2997      This changes TAF subroutine argument list (ordering of active var.)
2998      Omission of this flag leads to incompatibility w.r.t. TAMC
2999      To restore TAMC-compatibility, need following modifs:
3000      * use adoptfile tools/adjoint_options/adjoint_tamc_compatibility
3001      * use CPP option #define AUTODIFF_TAMC_COMPATIBILITY
3002      Tested TAF version is 1.9.22
3003      N.B.: exch2 hand-written adjoint code currently not TAMC compatible
3004    
3005    checkpoint60 (2008/06/19)
3006    --->>> This is the last checkpoint for which generating the adjoint
3007    --->>> is done via the TAMC-compatibility TAF-flag "-nonewarg"
3008    --->>> by default.
3009    --->>> Future checkpoints will ommit this flag by default.
3010    o pkg/generic_advdiff, os7mp: simplify and avoid division by zero.
3011    o pkg/grdchk: Add gradient check to etan0 perturbations.
3012    o pkg/exf: read ice area from file (#ifdef ALLOW_ICE_AREAMASK).
3013    o pkg/autodiff: more flexibility in zeroadj.
3014      model/src: modifying do_oceanic_phys.F accordingly.
3015    o pkg/ctrl: Bounds for (kapgm,kapredi,eddypsi) parameter estimation.
3016    o model/src and pkg/gmredi: GMREDI_WITH_STABLE_ADJOINT CPP option
3017      special setup of gmredi for which the adjoint is stable
3018      enough for parameter optimization.
3019    o bridging the gap between eddy stress and GM.
3020      -> eddyTau is replaced with eddyPsi (eddyTau = f x rho0 x eddyPsi)
3021          along with a change in CPP option (now ALLOW_EDDYPSI).
3022      -> when using GM w/ GM_AdvForm:
3023          The total eddy streamfunction (Psi = eddyPsi + K x Slope)
3024          is applied either in the tracer Eq. or in momentum Eq.
3025          depending on data.gmredi (intro. GM_InMomAsStress).
3026      -> ALLOW_EDDYPSI_CONTROL for estimation purpose.
3027      The key modifications are in model/src/taueddy_external_forcing.F
3028      pkg/gmredi/gmredi_calc_*F pkg/gmredi/gmredi_*transport.F
3029    
3030    checkpoint59r (2008/05/29)
3031    o new S/R (pkg/mdsio/mdsio_facef_read.F) reading of sNx+1 x sNy+1 array
3032      from per-face file (take S/R READSYMTILE_RS out of ini_curvilinear_grid.F);
3033      fix option to read coriolis(@ cell-corner) from files with CS-grid.
3034    o pkg/mnc: add some attributes to standard 1D-coordinate variables
3035    o pkg/diagnostics: enforce missing_value attribute for scalar variables at
3036      mass points, when using mnc for output
3037      - add runtime parameter (missing_value, missing_value_int) to override
3038        default (which is the value of getcon('UNDEF'))
3039    o pkg/mnc: prepare mnc for the actual use of missing values with the
3040      diagnostics package: small fix in mnc_cw_readwrite.template and more
3041      initialisation of never used fields
3042      - replace mnc_common.h and mnc_id_header.h with corresponding upper case
3043      versions
3044    o pkg/thsice/thsice_ini_vars.F added default initial values so that
3045      thermodynamics sea ice solver does not blow up when some initial fields
3046      are missing.
3047    o move from external_forcing_surf.F to ini_forcing.F
3048      the p-coord. hack consisting in using pLoad to set phi0surf ;
3049      update output of tutorial_global_oce_in_p (affected @ truncation level).
3050    o Freshen up a bit hs94.1x64x5, notably:
3051      remove rotationPeriod and tRef=5*0. (adjoint only), and add
3052      exactConserv=.TRUE.
3053    o pkg/generic_advdiff:
3054      change option GAD_ALLOW_SOM_ADVECT to GAD_ALLOW_TS_SOM_ADV which only
3055      applies to files where Temperature & Salinity 2nd Order moments are used.
3056    o pkg/ptracers: add second-order moment advection schemes (80 and 81);
3057      this uses a dynamically allocated internal state data structure
3058      (#define PTRACERS_ALLOW_DYN_STATE in PTRACERS_OPTIONS.h)
3059      and requires a fortran 90 compiler
3060    
3061    checkpoint59q (2008/05/06)
3062    o pkg/mom_vecinv: Add energy & enstrophy conserving scheme (selectVortScheme=3)
3063       (from Sadourny, described by Burridge & Haseler, ECMWF Rep.4, 1977)
3064    o Refresh tutorial_global_oce_biogeo, notably:
3065      - change bathymetry (put back seamounts in ACC, use hFacs)
3066      - change EOS (POLY3 --> JMD95Z)
3067      - use Bryan-Lewis vertical diffusivity
3068      - use multidimensional advection
3069      - remove old virtual virtual in dic pkg, now done through ptracer pkg
3070      - change a couple of parameters in dic pkg
3071    o pkg/ctrl: change formula in adctrl_bound.F and add a parameter to ctrl_map_ini_gen.F
3072    o pkg/obcs: change default to OBCSfixTopo = .true.,
3073      - set OBCSfixTopo=.false. in exp4/input/data.obcs to reproduce old result
3074      - replace "debugMode" with "debugLevel .GE. debLevB"
3075    o implementation of TAF directives for gchem,cfc,dic
3076    o remove "exp5" (replaced by tutorial_deep_convection).
3077    o pkg/obcs: add code to fix topography gradients normal to open boundaries;
3078      this requires computing the index fields OB_Jn/Js/Ie/Iw in obcs_readparms;
3079      the code can be turned on by setting OBCSfixTopo = .true. in data.obcs
3080      --> changes results in exp4, seaice_obcs
3081    o tutorial_deep_convection :
3082      update the set-up and increase resolution and domain size ; start
3083      from pseudo initial conditions = output at t=120mn in order to see
3084      something happening when running testreport.
3085    o pkg/seaice: add os7mp as an advection scheme
3086                  add check for advection schemes
3087                  add a flag for restoring T and S underneath sea ice
3088    o pkg/my82: add netcdf-support and diagnostics
3089    o thsice pkg:
3090      - Now hsMax limits snow height by turning it into ice following
3091        flooding scheme (and now conserving energy)
3092      - Slight rewriting of the formula in thsice_calc_thick.F
3093      - Parameter rhowi eliminated to be replaced by floodFac = (rhosw-rhoi)/rhos
3094      --> changes results of global_ocean.cs32x15.icedyn and global_ocean.cs32x15.thsice
3095    
3096    checkpoint59p (2008/04/10)
3097    o gchem / dic / cfc :
3098      - add useDIC, useCFC , read from "data.gchem" (& hold in GCHEM.h);
3099      - add new parameter files: "data.dic" & "data.cfc" ;
3100      - various re-arrangement in initialisation & header file ;
3101      - fix tutorial_global_oce_biogeo for multi-threaded test.
3102    o pkg/dic: test for "pickup_dic" file when restarting ;
3103      if no pickup-file, can restart with a re-initialised pH (same as it did
3104      before) providing pickupStrictlyMatch is set to False.
3105    o change argument list of S/R PTRACERS_WRITE_PICKUP & MYPACKAGE_WRITE_PICKUP
3106      + fix call to S/R GGL90_WRITE_PICKUP & DIC_WRITE_PICKUP
3107    o add a "warning" (to Error msg file) when an Active Tracer is not using AB-2
3108      and staggerTimeStep is off (needed for stability of Internal-wave dynamics).
3109    o move out of PARAMS.h & data the last pieces of old-ptracer code: tauTr1ClimRelax,
3110     & lambdaTr1ClimRelax ; put those 2 params in PTRACERS_PARAMS.h & data.ptracers
3111       (note: not clear to me what lambdaTr1ClimRelax is still used for ...)
3112    o pkg/mom_vecinv: - new parameter "selectVortScheme" to select which
3113       scheme to use for vorticty-term ;
3114     - compute upwindVorticity=T case within mom_vi_u/v_coriolis_c4.F
3115       (with default selectVortScheme, return to original discretisation)
3116     - remove weird combination (e.g.: upwindVorticity & highOrderVorticity)
3117    o pkg/seaice: add a line to the summary to indicate grid type (B/C)
3118    o in mom_calc_visc, fix average value of viscAh_W & viscA4_W next to the
3119      bottom ; only used with variable horizontal viscosity and non-hydrostatic.
3120      also fix diagnostics VISCAHW & VISCA4W.
3121    
3122    checkpoint59o (2008/03/07)
3123    o dome/code/obcs_calc.F: avoid division by zero (detected using gfortran).
3124    o change the loop ordering in most gad_*_adv_x.F to improve vectorization:
3125      move a few statemens out the main loop into separate loops
3126    o pkg/shelfice:
3127      - sort out freshwater flux; convert freshwater fluxes to mass fluxes
3128        (kg/m^2/s), does not break tests, because in verification/isomip,
3129        rhoConstFresh=rhoConst (by accident)
3130      - rearrange computation of tLoc, sLoc, pLoc to make code more efficient
3131      - move S/R find_rho_scalar, pkg/ecco/sw_ptmp.F, pkg/ecco/sw_adtg.F into
3132        new file model/src/seawater.F, so that they are available for all pkgs.
3133      - convert potential temperature into in-situ temperature. This changes the
3134        isomip tests => update tests
3135    o add a flag writePickupAtEnd (default=true) to be able to suppress
3136      writing a pickup at the last timestep
3137    o tools/mpack-1.6 :
3138      - disable automake (not working) and autoconf (not needed).
3139      - update to version 1.6.4 which fix MD5 code on some 64 bits platforms
3140        also cleaner with much less compilation warnings.
3141    o pkg/profiles:
3142      rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg
3143      (for "less than 32 characters name" compiler requirement)
3144    o pkg/obcs and pkg/exf: added capability to specify seaice open boundary
3145      conditions that have a different sampling frequency than S/T/U/V obcs
3146    o pkg/diagnostics (stats-diags):
3147      - fix global Min/Max in case 1 processor get only empty tiles
3148    o genmake2: replace (4 times)
3149         make genmake_tc_1.o >> genmake_warnings 2>&1
3150      with
3151         COMM="$CC $CFLAGS -c genmake_tc_1.c"
3152         echo $COMM >> genmake_warnings
3153         $COMM >> genmake_warnings 2>&1
3154      to make genmake2 always see the value of CC as specified in the optfile.
3155    o generic_advdiff: - prather advection scheme (SOM) coded for CS-grid.
3156      - add diagnostics for 1srt & 2nd Order moments and sub-grid variance.
3157      - modify verification advect_cs test to test SOM-advection on CS-grid.
3158    o pkg/ctrl:
3159      - Rewrite of ctrl_map_ini_ecco.F,
3160        introducing a generic routine (ctrl_map_ini_gen.F).
3161      - Modification of ctrl_bound/adctrl_bound handling control vector bounds.
3162    
3163    checkpoint59n (2008/02/09)
3164    o pkg/diagnostics: for large number of diagnostics, store diagnostic mate
3165      number in dedicate array "hdiag":
3166      - new version of S/R DIAGNOSTICS_ADD2LIST : DIAGNOSTICS_ADDTOLIST
3167        with 1 more argument (mate number); modify old version DIAGNOSTICS_ADD2LIST.
3168      - many small changes (integer format) for large number of diagnostics
3169      - start to use DIAGNOSTICS_ADDTOLIST (necessary for diagnostics with
3170        a counter mate) in pkg diagnostics, ptracers, thsice & aim_v23.
3171    o add parameter rotateGrid and Euler angles EulerPhi/Theta/Psi. For
3172      usingSphericalGrid, this allows to define the rotated grid coordinates
3173      via phiMin/thetaMin/dxSpacing/dySpacing, etc., but then re-compute the
3174      geographical coordinates according to the inverse of the rotation defined
3175      by the Euler angles, so that Coriolis parameter and online-interpolation by
3176      exf works with the geographical coordinates on XC/YC/XG/YG.
3177      Naturally, this feature does not work with all packages, so some
3178      combinations are prohibited in config_summary (flt, flt_zonal, ecco,
3179      profiles), because there the coordinates are assumed to be regular
3180      spherical grid coordinates.
3181    o pkg/gmredi,ctrl,ecco,autodiff,grdchk and model/src,inc:
3182      - introduce isopycnal diffusion coefficient control.
3183    o tools/adjoint_options:
3184      - additional control vector components.
3185    o pkg/mnc: have mnc create marginally meaning full coordinate variables
3186      (that is the grid indices) if usingCurvilinearGrid and NOT EXCH2
3187    o pkg/mypackage:
3188      - add example of read/write pickup for state-var ;
3189      - add entry points to the main code for state-vars diags & write-pickup.
3190    o pkg/exf: rewrite of exf_getffieldrec.F to properly deal with year
3191      transitions for useExfYearlyFields
3192      - add new subroutine that determines the file to read from for
3193        use*YearlyFields = .TRUE. and .FALSE.
3194      - add a verification experiment to global_with_exf that tests
3195        useExfYearlyFields with USE_EXF_INTERPOLATION defined
3196    o pkg/obcs/exf: add useOBCSYearlyFields (=.FALSE.) to obcs with exf in
3197      analogy to useExfYearlyFields; rearrange obcs_prescribe_read: two new
3198      subroutines (which could be generated from a template, because they are
3199      almost identical), for now they are included in obcs_prescribe_read.F for
3200      simplicity
3201    o pkg/exf:
3202      - add a little more diagnostic to exf_interp_read (in analogy to
3203        mds_read_field, can be turned off with debugLevel < debugLevA=1)
3204      - improve vectorizability of exf_interp for TARGET_NEC_SX, makes code
3205        ugly but fast by unrolling short inner loops, inserting a unroll=8
3206        directive in routine lagran, and splitting a loop and making do while the
3207        outermost loop (the latter requires the intoduction of index arrays)
3208    o pkg/obcs: replace obcs_apply_area/heff/hsalt/hsnow with obcs_apply_seaice
3209    o pkg/seaice: moved DIFFERENT_MULTIPLE from seaice_model to seaice_dynsolver
3210      http://forge.csail.mit.edu/pipermail/mitgcm-devel/2008-January/003173.html
3211    o verification/seaice_obcs: updated for restart test and latest options
3212    o pkg/seaice: add a new flag SEAICEuseTEM to use a slightly different
3213      ice rheology (so-called truncated ellipse, that gets rid of tensile stress);
3214      for now this is only available for the C-grid code and also within
3215      #ifdef SEAICE_ALLOW_TEM, because this option may slow down the EVP code
3216    
3217    checkpoint59m (2008/01/14)
3218    o pkg/seaice: use different time constant for melting (SEAICE_gamma_t)
3219      and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature
3220    o gad_som : fix flux output (& diagnostics) to have same units as other  
3221      advection scheme fluxes (was previously multiplied by deltaT).  
3222    o added verification/seaice_obcs both to test seaice open boundaries
3223      and to provide an example matlab scrpt for generating them
3224    o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume
3225    o pkg/salt_plume: clean up salt_plume_frac.F to
3226      remove redundancy in PlumeMethod 1 and 4
3227    o pkg/kpp: added saltplume diagnostics
3228    o pkg/obcs and pkg/seaice:
3229      - do not set uice and vice to zero when OB*icefile are unspecified
3230      - OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default
3231      - moved seaice tracer obcs after call to seaice_growth
3232    o pkg/salt_plume: added various options for salt plume depth
3233      criterion and for vertical distribution of the salt
3234    
3235    checkpoint59l (2007/12/18)
3236    o pkg/ptracers: new version of ptracers pickup:
3237      read meta file and write only fields which are needed to restart.
3238      ( same logic as main pickup file ; also using pickupStrictlyMatch )
3239    o pkg/seaice:
3240      - add timescale for melting due to warm mixed layer as a means of
3241        setting SEAICE_availHeatFrac more conveniently
3242      - add a CPP-flag/runtime parameter check for flooding algorithm
3243      - reformulated availHeat in seaice_growth.F to be independent of AREA
3244    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
3245      unit changes
3246    o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
3247    o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
3248      SX vector computer.
3249    o pkg/seaice:
3250      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
3251        seaice forcing fields can now be read only through pkg/exf
3252      - removed some unused halos
3253    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
3254    o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
3255      or U/VICE from U/VWIND before computing U/VSTRESS
3256    
3257    checkpoint59k (2007/11/30)
3258    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
3259      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
3260    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
3261      all experiments pass when compile with un-initialised var. checking option.
3262    o added pkg/salt_plume
3263    o script to test restart (for now, in MITgcm_contrib/jmc_script)
3264    o pkg/seaice: new read/write pickup version.
3265      read meta file and write only fields which are needed to restart.
3266      ( same logic as main pickup file ; also using pickupStrictlyMatch )
3267    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
3268    o lab_sea.hb87: modify the domain & update output.hb87.txt :
3269      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
3270      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
3271      process. Fixed here by closing the domain at the Northern boundary.
3272    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
3273    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
3274      a set of consecutive levels in/from a 3-D array.
3275    o pkg/ptracers:
3276      use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
3277      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
3278    
3279    checkpoint59j (2007/11/09)
3280    o in pkgs: dic, obcs, offline, rbcs:
3281      standard way to compute coeff. for time interpolation between 2 time reccords
3282      which retains full precision (& make results less dependent on compiler).
3283      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
3284    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
3285      packages instead of reading ice cover and wind speed separately
3286    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
3287     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
3288      to allow to compile customized code before the update)
3289    o cleaning-up:
3290      - fix CPP instruction syntax in pkg/obcs
3291      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
3292        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
3293      - fix some threads issue in IO parts.
3294    o pkg/dic:
3295      - add tons of "_d 0" (--> much better testreports !)
3296       and then update outputs of tutorial_global_oce_biogeo
3297    o pkg/mom_fluxform:
3298      add a special version of momentum advection intended to conserve momentum
3299      next to a bathymetry step or a coastline edge. (default = off = #undef)
3300    o new read/write pickup version:
3301      - for now, only implemented for main (mdsio) pickup file.
3302      - write out only what is needed to restart; merge pickup_nh , pickup_ph
3303        and main pickup together.
3304      - read meta file; read only what is needed to restart; stop if a field
3305        is missing (if pickupStrictlyMatch=T, = the default) or try to restart
3306        if it make sense (even if the restart is not perfect).
3307      - if no meta file, assume that pickup to read corresponds exactly to
3308        a pickup that would currently be written.
3309      - read pickup written in the old format (until checkpoint59i) if it
3310        recognizes an old meta file (no field-list).
3311      - add a meta file in exp. which starts from a pickup: 2 cases:
3312        a) minimal meta file (with just file precision) + pickupStrictlyMatch=F
3313         e.g.: global_ocean.90x40x15/input/pickup.0000036000.meta
3314        b) a meta file describing the content of the associated pickup file
3315         e.g.: tutorial_global_oce_biogeo/input/pickup.0004248000.meta
3316    o pkg/mdsio & pkg/rw:
3317      - new routine to read a meta file ; new set of routine to read
3318        Multiple-fields file (with meta file).
3319    o added open boundary conditions capability for seaice
3320        HSNOW, HSALT, UICE, and VICE
3321    
3322    checkpoint59i (2007/10/21)
3323    o adjoint:
3324      * fix multiDimAdvection adjoint
3325        (partial recomputation problem by TAF for fVerT(:,:,kDown)
3326        and comlev1 size definition (maxpass vs. max. number of tracers)
3327      * verification/global_ocean.90x45x15 adjoint now tests
3328        NLFS and multiDimAdvection using DST3 (=30)
3329      * verification/lab_sea now tests multiDimAdvection using DST3 (=30)
3330    o pkg/kpp: add "_d 0" to real constant (if missing);
3331      update output of exp: natl_box (10.digits); vermix (std, 7.digits)
3332      and lab_sea, 3.FW (only 6,4,6 digits match) & AD (8.digits).
3333    o prepare for "clever pickup" implementation: add new header file "RESTART.h"
3334      for internal parameters related to restart process (formerly from PARAMS.h)
3335      and add startAB parameter to argument list of S/R ADAMS_BASHFORTH2.
3336    o more standard interface to {PKG}_WRITE_PICKUP with pickup suffix passed
3337      as argument. (only atm2d & obcs write_pickup have not yet been updated)
3338    o pkg/monitor:
3339      - use GLOBAL_SUM_TILE instead of _GLOBAL_SUM
3340      - fix mon_stats_rs (statistics over the full domain, even where field is zero)
3341      - account for deep Atmosphere factor and density factor (anelastic)
3342    o added open boundary conditions capability for seaice HEFF and AREA
3343    o pkg/shelfice: add option for convservative form of Hellmer&Olbers (1989)
3344      thermodynamics
3345      - requires a little reorganization, which affects the testreport results
3346        of isomip.htd (only 7 digits of cg2d agree) => update/modify experiment,
3347        so that now the conservative form is tested
3348      - add a few comments
3349    o add missing cvs Header: or Name: in eesupp/*, pkg/* & verification/code*
3350    o add a little bit of code to gad_os7mp_adv_?.F to help vectorization
3351    o add new diagnostics to seaice: advective, diffusive fluxes (only for
3352      multidim-advection, for scheme 2 they are not filled) and transports,
3353      thermodynamic growth rates
3354    o change units of EmPmR (inside the code, + within coupling interface)
3355      from m/s to kg/m2/s (mass flux) but leave input file unchanged.
3356      Affects results @ truncation level (cg2d match) and update output of
3357       experiments: lab_sea(6), global_ocean.90x40x15(10),
3358      global_ocean.cs32x15(11x3,10), natl_box(11), tutorial_global_oce_latlon(11)
3359      + adjoint results: global_ocean_ebm(11) and lab_sea (12).
3360      Coupled set-up: allow to restart from previous pickups (cpl_oldPickup=T).
3361      Next: will retire convertEmP2rUnit (simply using mass2rUnit instead).
3362    
3363    checkpoint59h (2007/09/29)
3364    o pkg/exf:
3365      - improve vectorization by moving if-statement out of loops in
3366        exf_mapfields, exf_radiation
3367      - exf_bulkformulae.F: introduce 2D fields and vectorize code
3368    o pkg/kpp: added the salt plume scheme (ALLOW_SALT_PLUME) to KPP package
3369    o testreport:
3370      - allow to test for Qnet & SeaIce monitor output; clean-up ALLOW_BULK_OFFLINE
3371        monitor & update offline_exf_seaice exp. output.
3372      - AD testing: pass/FAIL according to Grad. output accuracy (instead of Cost)
3373    o pkg/seaice:
3374      - bug fix in the evp solver: boundary conditions were affected be
3375        masking of zMax/zMin (changes results)
3376      - minor bug fix in boundary conditions in seaice_calc_strainrates
3377        (changes results for no_slip)
3378      - seaice_lsr.F: make interpolation of eta dependent on boundaries
3379      - replace hardcoded lower limit for zeta (zMin) by runtime parameter
3380      - add a test to lab_sea, that tests the Hibler and Bryan (1987) ocean
3381        stress formulation and no-slip boundary conditions
3382    o pkg/ptracers: Temporary fix for PTRACERS_useGMRedi & PTRACERS_useKPP
3383      in gad_calc_rhs.F ; add few safety stops in initialisation phase.
3384    o pkg/seaice: a first HSALT time stepping equation has been checked in
3385    o pkg/seaice: replaced maskW with seaiceMaskU and maskS with seaiceMaskV
3386      in seaice_lsr.F; this solves the pkg/seaice-pkg/obcs problem
3387      without requiring DO-IF statements
3388    o pkg/thsice:
3389      use continuous power-law function for partition of energy between lateral
3390      melting/freezing and thinning/thickening ; old code using step function
3391      still available with #undef THSICE_FRACEN_POWERLAW
3392      update output of exp: aim.5l_cs.thSI, global_ocean.cs32x15.icedyn & .thsice
3393    o testreport: change AD testing : check against results/output_adm.txt
3394      using same scripts as for forward test.
3395    
3396    checkpoint59g (2007/09/17)
3397    o adjoint testing: in preparation for changing testreport:
3398      - output format: cost and grad written on separated lines
3399      - ad output results in directory "results" (instead of "results_ad")
3400    o pkg/seaice: adding ice salinity HSALT as a prognostic variable
3401    o pkg/seaice: changes for using pkg/seaice with pkg/obcs
3402    o pkg/ecco: allow user defined cost function contributions
3403    o testreport:
3404      Allow to choose (per experiment) the list of tested output variables
3405       and the main variable (used to issue a pass/FAIL ) ;
3406      - for now, done by adding the specific list in file: [exp]/input/tr_checklist
3407      - default is unchanged: >cg2d< , (T,S,U,V,5 tracers)_[min,max,mean,StD] ;
3408      Also modify printing of summary:
3409       a) ">" NN "<" indicates the "main" variable (used for pass/FAIL)
3410       b) echo the list of tested variables in the individual summary.txt of
3411          each experiment.
3412    o new S/R GLOBAL_SUM_TILE to compute global sum independently of number of
3413      threads and number of processes (with #define GLOBAL_SUM_SEND_RECV)
3414      (but still depend on the tile decompostion of the domain).
3415    o pkg/seaice: change a discretization detail to make the B-grid code
3416      "more symmetric". This change is likely to remove all "ridges/leads" that
3417      where quasi-aligned with the grid in B-grid solutions. It may also be
3418      the solution to the stress coupling issues with the B-grid.
3419    o each tested exp: add a "run" directory with a standard ".cvsignore" file ;
3420      remove .cvsignore from input dir. (since testreport no longer run here).
3421    o pkg/thsice:
3422     - cleaning: move common block out of "THSICE_2DYN.h" (removed) to "THSICE_VARS.h"
3423     - fix reshaping of sea-ice just after advection:
3424       melt all the ice only if ice-volume is too small.
3425     - re-visit lateral/thinning repartition of melting (modifs from May 04, 2007):
3426       prevent lateral melting if sea-ice fraction is too close to iceMaskMin ;
3427     and update experiment global_ocean.cs32x15.icedyn (+start from pickup files).
3428    o external_forcing_surf : extend the use of salt_EvPrRn & temp_EvPrRn (fresh-water
3429      tracer content) to linFS or no RealFreshWaterFlux ; default remains unchanged.
3430    o define mass2rUnit & rUnit2mass as units conversion factor, used for surface
3431      forcing. mass2rUnit: from mass per unit area [kg/m2] to r-coordinate unit
3432      (z-coord: =1/rhoConst ; p-coord: =gravity) ; rUnit2mass is just the reverse;
3433      and remove horiVertRatio (& recip_horiVertRatio). Affects truncation error
3434      of exp. global_oce_in_p: 10 16 16 14 16 13 16 16 16 13 13 13 16 13 13 12 16
3435      -> update output.txt
3436    o pkg/cd_code: add brackets in multiple terms sum (S/R CD_CODE_SCHEME):
3437     this affects truncation error: -> update output.txt of exp:
3438      global_ocean.90x40x15 (fw&adm), lab_sea (fw&adm) & lab_sea.lsr,
3439      ideal_2D_oce, isomip.htd, natl_box, tutorial_global_oce_latlon.
3440    
3441    checkpoint59f (2007/08/21)
3442    o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode)
3443    o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in
3444      a bounded range (in forward mode)
3445    o pkg/ecco, ctrl, autodiff and mom_common:
3446     internal parameter controls, completements of implementations
3447    o add few EXCH S/R (UV_BGRID, UV_DGRID, SM) for B & D-Grid velocity & 2nd Moment Sxy.
3448    o use UV_BGRID exch for dxV,dyU: for now, only with pkg/exch2 & forward ;
3449      (not seem any difference in testing results).
3450    o pkg/cd_code: use the right EXCH calls (for CS-grid); but problem remains
3451       at face corners.
3452    o pkg/generic_advdiff:
3453     - in GAD.h, define as parameters (iMinAdvR,iMaxAdvR,jMinAdvR,jMaxAdvR)
3454      loop range indices for computing vertical advection tendency
3455      and do the calculation in the interior only (no overlap) ;
3456      for now, only implemented for SOM advection (to save CPU time).
3457     - add argument "withSigns" to S/R FILL_CS_CORNER_TR_RL (needed for SOM_xy moment)
3458    o exch2 adjoint
3459      First set of changes:
3460      - add exch2 hand-written adjoint templates
3461      - exch2 hand-written no longer use TAF-flag 'nownew_arg'
3462        This will require cleanup in pkg/autodiff/*.F
3463        (changed routines currently kept separate in verif. code/)
3464      - Comment all relevant #ifndef ALLOW_AUTODIFF_TAMC
3465        that used to hide exch2 or cubed-sphere specific code
3466        (commented via 'cph-exch2')
3467    o pkg/seaice
3468      - Close southern and western boundaries for UICE/VICE when useOBCS=.TRUE.
3469    o pkg/bulk_force: fix loading into Qsw of Short-Wave flux; and update
3470       output of global_ocean.cs32x15.thsice .
3471    
3472    checkpoint59e (2007/07/26)
3473    o exch2: new S/R that only use the cube-tracer (center-position) exchange:
3474      for B-grid vector (not yet tested) and C-grid vector (<- only used
3475      when option W2_USE_R1_ONLY in W2_OPTIONS.h is defined).
3476    o starting implementation of Duffy et al. (GRL 1999) salt plume scheme
3477      (#ifdef ALLOW_SALT_PLUME)
3478    o gather_2d/scatter_2d: removed halo regions
3479    o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
3480      scheme and the corresponding test case (under front_relax dir). For now,
3481      only available with Skew-flux form and not yet tested in realistic set-up.
3482      adjoint: store directives updated, but gradient checks deteriorated,
3483      so maybe GM/Redi adjoint is now broken.
3484    o seaice adjoint
3485      * add AREA, HEFF, HSNOW as control variable
3486        (should not change lab_sea results)
3487      * CTRL_OPTIONS.h needs new flag: CTRL_SET_OLD_MAXCVARS_40
3488    o pkg/seaice:
3489      * added computation of saltFlux in seaice_growth;
3490        For time being, sea ice salinity is assumed constant
3491        contribution of snow flooding to freshening of sea ice is neglected.
3492        SEAICE_salinity is set in SEAICE_PARM01 of data.seaice and it
3493        defaults to 0.0 in order to maintain backward compatibility.
3494        Typical values for SEAICE_salinity are 4 to 10 g/kg.
3495      * replaced dRf(1) with dRf(kSurface)*hFacC(kSurface) in seaice_growth.F
3496      * added SEAICE_availHeatFrac, which specifies fraction of surface level
3497        heat content used to melt or grow ice
3498      * commented out cap of HICE: it helps keep ice thinner
3499      * reintroduced cap of HEFF via MAX_HEFF and SEAICE_CAP_HEFF option
3500      * applied OBCS T/S mask to HEFFM sea ice mask
3501    
3502    checkpoint59d (2007/06/21)
3503    o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
3504     for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
3505     (keep {PKG}_DIAGNOSTICS_FILL for non-state variables diagnostics)
3506    o pkg/gmredi (gmredi_readparms.F): add some missing "_d 0"
3507     and change default value of parameter "GM_Small_Number";
3508     update output of exp: lab_sea (x2), cfc_example, global_ocean.90x40x15,
3509       global_ocean.cs32x15 (x4), global_ocean_ebm, global_with_exf,  
3510       tutorial_global_oce_biogeo, tutorial_global_oce_latlon
3511    o pkg/ecco: cost function when applying pkg/smooth to controls
3512    o pkg/ctrl: add forcingPrecond run time parameter
3513    o pkg/seaice:
3514     - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code
3515     - fix bug in metric terms of u-equation in LSR solver (implicit part),
3516       changes verification/lab_sea
3517     - rearrange implicit part of u-equation in LSR solver to make it easier to
3518       read, understand, and debug. This causes changes at the truncation level.
3519     - fix (serious) bug in the boundary conditions (sign error in the implicit
3520       part) of the LSR solver. Changes all LSR results.
3521     - fixed problem with HSNOW initialization to avoid thick snow when AREA
3522       is initilized with small values - does not change lab_sea results.
3523     - added HsnowFile initialization capability
3524    o pkg/smooth: addition to model/src and pkg/ctrl so allow
3525     initialization of pkg/smooth and application to control vector
3526    o pkg/seaice: fix another bug in the LSR no-slip boundary conditons
3527    o dependencies: pkg/profiles requires pkg/cal
3528    o pkg/profiles:
3529     - added option ALLOW_PROFILES_GENERICGRID
3530         -> pkg/profiles can thus be used with any grid (e.g. cs32x15) assuming
3531         that interpolation information (grid points and coefficients) is provided
3532         within the netcdf input files.
3533         -> sample matlab scripts can be found in MITgcm_contrib/gael
3534         that allow you to prepare netcdf input files.
3535     - also modified: cleaner include statements, cleaner error print statements,
3536       cleaner stops when error, and more tests of the netcdf input files consistency.
3537    o additional test (in global_ocean.cs32x15) using seaice+thsice pkgs.
3538    o pkg/seaice:
3539     - move seaice-diagnostics from seaice_do_diags to do_statevars_diags; this
3540       requires a new routine: seaice_diagnostics_fill.F
3541     - make sure that seaice does not move if not forced (pressure replacement
3542       method, Hibler and Ip, 1995), changes results
3543     - and new damping criterion for EVP solver according to Hunke, JCP, 2001
3544     - SEAICE_evpDampC = > 0. turns it on (615. is the recommended value).
3545       It is turned off by default (=-1.), because it changes the results.
3546     - make it possible to read AREA from a file, too.
3547    
3548    checkpoint59c (2007/06/04)
3549    o add S/R and diagnostics for oceanic mixed-layer depth
3550    o move GMRedi call after all vertical mixing schemes (including KPP)
3551    o pkg/thsice:
3552     - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
3553      (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
3554    o pkg/obcs:
3555     - bug fix for balance code
3556    o pkg/seaice:
3557      - allow values of SEAICE_elasticParm > 1
3558      - add new parameter SEAICE_evpTauRelax as an alternative
3559        to SEAICE_elasticParm
3560      - make lsr boundary conditions free slip (by default), changes result
3561      - add code for no slip boundary conditions for lsr
3562      - set minimum of zeta to zero (and not 4e8) (changes results)
3563      - add a cap on AREA after advecting AREA if seaice_growth is not called
3564    o change calculation of Visbeck K:
3565      - no longer depend on tapering scheme; instead, compute slope (limited
3566        by GM_maxSlope). this is equivalent to what was comuted before with
3567        clipping or linear tappering.
3568      - fix vertical averaging (wrong by 1/2 level)
3569      - leave the old version (but will not be maintained) within
3570        #ifdef OLD_VISBECK_CALC / #endif
3571      - update output of exp. ideal_2D_oce
3572    o change error catch in calc_r_star to improve vectorization
3573    o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and
3574      add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
3575    o adjoint:
3576      Re-organized adjoint checkpointing according to Matt Mazloff
3577      (but with modifs/completions/cleanups)
3578      Storing is now bundled into large arrays to optimized I/O
3579      (and second step in cleanup of the_main_loop)
3580    
3581    checkpoint59b (2007/05/16)
3582    o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
3583      - export/import (between ocean & coupler) fields needed for ocean DIC.
3584    o pkg/seaice:
3585      - get rid of three more exchanges seaice_calc_viscosities (required
3586        different loop boundaries in seaice_lsr and seaice_ocean_stress)
3587      - bug fix in seaice_ocean_stress (update of lab_sea required)
3588      - reduce loop boundaries to necessary minimum also in seaice_evp
3589      - go back to the old way of computing deltaC/Z as the adjoint likes that
3590        better
3591    o Refresh of tutorial_global_oce_latlon (includes changing salinity-like
3592      passive tracer to an Age Tracer) + update output.txt
3593    o pkg/exf:
3594      - implement A-grid / C-grid selection for wind-stress input files.
