4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/seaice: fix multithreading for seaice_fgmres.F
8      - remove unecessary variables from common blocks
9      - use extra dimension MAX_NO_THREADS for all variables of the Krylov
10        space basis, that are stored in commom blocks (including integer
11        variable i1)
12      - clean up code a little by removing commented lines that refer to
13        original code
14    o MITgcm manual:
15     - add uptodate pkg/ecco documentation to the manual (section 8.1;
16       ecco.tex), preliminary documentation for generic controls (8.3;
17       ctrl.tex), a placeholder for smooth (8.4; smooth.tex), and
18       comment out the deprecated ecco_costfunction.tex
19    o pkg/ecco:
20     - update and cleanup list of CCP options
21     - re-assign gencost_mask to specify masks rather than gencost_errfile; 'c'
22       is now always passed to cost_generic; gencost_mask is now MAX_LEN_FNAM
23     - add checks that retired run-time options are not used, and in relation
24       to gencost_mask and gencost_errfile
25     - finish deprecating gencost_scalefile, gencost_smooth2Ddiffnbt, and
26       gencost_nrecperiod
27     - fix m_eta computation for virtual salt flux case
28     - add m_horflux_vol case (selected via gencost_barfile) that computes
29       transports via cost_gencost_boxmean (gencost_flag=-3)
30     - use gencost_flag more systematically (i.e., avoid using gencost_name)
31       for code switches (aside from physical variable selection)
32    o pkg/seaice: make seaice_fgmres.F fit for multithreading; this first
33      attempt appears to be a bit of a hack and my need some repair down the road
34    o pkg/exf:
35      - interpolation near South Pole: fix criteria on input field latitude.
36    o pkg/icefront & pkg/exf:
37      - move setting of icefront Sub-Glacial RunOff forcing (currently unused)
38        from pkg/exf (read from data.exf) to pkg/icefront (read from data.icefront)
39    o pkg/exf:
40      - replace CPP option ALLOW_EXF_OUTPUT_INTERP with run-time parameter
41        "exf_output_interp" (in namelist: EXF_NML_04); change output file name
42        (add suffix "_out" instead of a prefix); keep same record number as in
43        input file but always write record 1 first (to avoid a STOP in I/O S/R).
44        Change output file content by writing interpolated field before applying
45        land-sea mask (helpful for debug).
46      - 2 compon. vector interpolation with rotation: apply scaling factor on
47        each compon. (Eastward and Northward) just before rotation.
48    o pkg/bling:
49      - Cleaned package. Removed not needed code and comments.
50      - adjoint example now works
51        (MITgcm_contrib/verification_other/global_oce_biogeo_bling/code_ad)
52    o pkg/ptracers:
53      - add Bruno Deremble's code to complete the linear surface correction
54        for tracer conservation;
55      - enabled for individual ptracers by PTRACERS_linFSConserve(iTr)=.TRUE.
56    
57    checkpoint65y (2016/07/29)
58    o pkg/debug (stats):
59      - change GLOBAL_SUM to GLOBAL_SUM_TILE (result independent of tile to
60        proc/thread mapping);
61      - fix Min & Max for case where 1 thread has only empty tiles;
62      - use RL variable to count number of wet grid points (with big domain,
63        can be too large to fit into integer*4).
64    o pkg/monitor:
65      - use RL variable to count number of wet grid points (but used only for del2)
66      - add new routine to compute Advective CFL within tracer time-stepping with
67        writing delayed until next monitor output.
68    o pkg/obcs:
69      - fix bug in OBCS_BALANCE_FLOW (OBCS_balanceFacN misspelled OBCS_balanceFacW)
70    o pkg/cal:
71      - calandar-dump: treat case myTime < timePhase in the same way as in
72        eesupp/src/diff_phase_multiple.F (when not using calandar-dump).
73    o pkg/dic & seaice:
74      - fix compilation of ocean component for coupled atm+ocn model with
75        seaice dynamics & dic.
76    
77    checkpoint65x (2016/06/11)
78    o add a license text file in main MITgcm tree.
79    o added pkg/bling:
80      - intermediate complexity biogeochemical model
81      - see bling_description.txt for details
82      - verification experiment is global_oce_biogeo_bling (for now, in
83        Contrib/verification_other/); tested daily on baudelaire with gfortran.
84      - add entry point in pkg/gchem for new pkg "bling".
85    o pkg/seaice: fix tensile stength computation
86      - replace global field tensileStrength by tensileStrFac
87      - tensileStrFac can be computed once in S/R seaice_init_varia
88      - fortunately that does not affect any verification results
89    
90    checkpoint65w (2016/05/12)
91    o pkg/ctrl/ctrl.h: fix a comma in common block list, so that code compiles
92         with ECCO_CTRL_DEPRECATED defined
93    o verification/global_ocean.cs32x15:
94      - change secondary test "viscA4" to also test "selectP_inEOS_Zc=3"
95        with "selectNHfreeSurf=1".
96    o model/src (non-hydrostatic free-surface):
97      - More "natural" expression of NH free-surface term (case selectNHfreeSurf=1):
98        was: tmpSurf/(1+tmpSurf); changed to: 1/(1+Gamma) with Gamma=1/tmpSurf.
99      - Calculate surface vertical velocity after 2-D solver adjustment (accounts
100        for EmPmR if RealFreshWaterFlux); used in RHS (cg3d_b) if exactConserv
101        and used to compute dPhiNH (in post_cg3d.F) if selectNHfreeSurf=1.
102        This fixes EmPmR contribution when selectNHfreeSurf=1 & RealFreshWaterFlux.
103      - Update output (changes at machine truncation level) of verification exp:
104        exp4 (11 digits for cg2d), global_ocean.cs32x15.viscA4 (11.d),
105        short_surf_wave (13.d) and tutorial_deep_convection.smag3d (12.d).
106    o pkg/seaice: ITD code
107      - fix picking up from a single category model by initialising
108        heff/area/hsnowITD = 0. in seaice_itd_pickup.F
109      - split a long warning message in seaice_check_pickup.F into two lines,
110        because NEC SX-ACE cannot deal with the long line.
111    o model/src:
112      - fix missing dPhiNH in pressure_for_eos.F (case: selectP_inEOS_Zc=3)
113    o pkg/seaice:
114      - add missing checks for SEAICE_ALLOW_KRYLOV and SEAICE_ALLOW_BOTTOMDRAG
115    o pkg/seaice:
116      - add basal stress as parameterisation for grounding ice
117        following Lemieux et al. (2015)
118      - turn on by setting new parameter SEAICEbasalDragK2 to a value
119        larger than 0. Lemieux et al. (2015) recommend 15.
120      - The adjoint complains with extra recomputations so there is also a
121        new cpp-flag SEAICE_ALLOW_BOTTOMDRAG that is undefined by default in
122        order to postpone the problem
123      - compile the new code in lab_sea
124    o verification/halfpipe_streamice:
125      - update both TAF and OpenAD adm output (machine truncation differences)
126    
127    checkpoint65v (2016/04/08)
128    o verification/advect_xz:
129      - increase overlap size from 3 to 4 and add new secondary test for PQM
130        advection scheme (with mono & wino limiter).
131      - change main exp. to test PPM (with weno limiter) adv.scheme on Temp.
132    o model/src:
133      - new parameters "top_Pres" & "seaLev_Z" (replacing Ro_SeaLevel and recently
134        added phi0Ref) to set vertical axis origin and phiRef origin;
135        keep Ro_SeaLevel for backward compatibility (with a warning).
136       According to coordinate and fluid type:
137        OCN in Z: top_Pres(Ref) (=rhoConst*PhiRef(1)), seaLev_Z (=rF(1), @ the top)
138        ATM in Z: top_Pres(Ref) (=rhoConst*PhiRef(1)), seaLev_Z (=rF(Nr+1) @ bottom)
139        OCN in P: top_Pres (=rF(Nr+1)), seaLev_Z (= PhiRef(Nr+1)/g, @ the top)
140        ATM in P: top_Pres (=rF(Nr+1)), seaLev_Z (= PhiRef(1)/g, @ the bottom)
141      - remove Ro_SeaLevel from ATM experiment parameter files;
142      - in tutorial_global_oce_in_p, remove Ro_SeaLevel and set top_Pres to the
143        complement; update output.txt (changes at machine truncation level).
144    o pkg/seaice/seaice_evp.F
145      - simplify computation of deltaZ and zetaZ to simple averaging following
146        Bouillon et al. (2013). This removes a lot of code, but also changes
147        verification experiment lab_sea.hb87 -> updated
148    
149    checkpoint65u (2016/03/14)
150    o pkg/generic_advdiff:
151      - from Darren: add PPM and PQM advection schemes (number 40-42 and 50-52)
152        with 2 types of limiter (see: Engwirda & Kelley, submit. to JCP);
153        Note (from Darren): unlimited PPM/PQM scheme (40 & 50) are just for
154        testing and not for actual use.
155    o model/src:
156      - add parameter "phi0Ref" to specify reference [pressure/geo] potential at
157        origin r = rF(1);
158      - add options (parameter selectP_inEOS_Zc) to select which pressure to use
159        in EOS for height coordinate: enable to include NH Pressure or to use
160        more accurate pressure vertical profile; options not linked to EOS type
161        (as previously, e.g., JMD95P/JMD95Z) but set default according to EOS type;
162      - start to implement variable gravity (along vertical): for now, only with
163        z-coords (not even z*).
164      - add Ideal Gas equation of state for height coordinate.
165      - update OpenAD output (affected at machine truncation level) of exp:
166        global_ocean.90x40x15, OpenAD (std) and tutorial_global_oce_biogeo.
167    o pkg/exf:
168      - add ALLOW_EXF_OUTPUT_INTERP cpp switch to output the result
169        of exf interpolation (before any rescaling, rotation or interpolation
170        to velocity point) for each field that gets loaded from file. This option
171        identically mimics the input file organization (e.g. record numbers in year
172        by year input files) besides the change in horizontal grid.
173      - add rotateStressOnAgrid run-time switch so that wind stress fields
174        can be provided on the A-grid in zonal/meridional direction and
175        rotated on the fly. This only applies to the case when the exf
176        interpolation is off and rotateStressOnAgrid is false by default.
177    o model/src:
178      - rename internal parameter "useDynP_inEos_Zc" to "storePhiHyd4Phys" (since
179        it's also used with pkg/atm_phys) and add few more parameters (but still
180        inactive, src code yet to come)
181    
182    checkpoint65t (2016/02/10)
183    o pkg/atm_phys:
184      - from Ruth Geen: add optical depth dependence on CO2 concentration.
185    o model/src:
186      - fix vertical inter/extra-polation of density factor rhoFacF (for anelastic)
187        for the case setCenterDr=T (delRc set from "data"); add output of rhoFacC&F.
188        Update output of exp. deep_anelastic (changes at truncation level).
189    o tools:
190      - add a hack in "remove_comments_sed" (used only with TAF) for recent
191        version of OpenMPI (shipped with FC.23): comment out the new header
192        file "mpif-sizeof.h" which causes problems to TAF.
193    o pkg/seaice:
194      - change the termination criterion so that maxits (SEAICElinearIterMax)
195        has an effect
196      - unify iteration parameters for implicit solvers (JFNK and Picard)
197        SEAICEnonLinIterMax replaces SEAICEnewtonIterMax/NPSEUDOTIMESTEPS
198        SEAICElinearIterMax replaces SEAICEkrylovIterMax/SOLV_MAX_ITER
199        SEAICEpreLinIterMax replaces SOLV_MAX_ITER in preconditioner
200        SEAICEpreNL_IterMax replaces NPSEUDOTIMESTEPS in preconditioner
201        SEAICEnonLinTol     replaces JFNKgamma_nonlin
202      - remove S/R SEAICE_FGMRES_DRIVER and put content into S/R SEAICE_JFKN
203      - add new Picard-Krylov solver, compile with SEAICE_ALLOW_KRYLOV and
204        use with SEAICEuseKrylov
205    o pkg/seaice/seaice_lsr.F
206        fix small bug: replace zetaZ by zetaZloc in S/R seaice_lsr_rhsu/v; only
207        relevant if SEAICEuseStrImpCpl=T, and even then it does not seem to have
208        an effect.
209    o pkg/seaice: add two new parameters
210      - SEAICEuseLSR to simplify the logic in seaice_dynsolver (this
211        parameter is not in any namelist)
212      - SEAICEusrPicardAsPrecon to allow s/r seaice_lsr to be used as
213        a preconditioner for the non-linear Newton iteration of the JFNK
214        solver
215    o pkg/seaice/seaice_lsr.F: replace 1./SEAICE_deltaTdyn with recip_deltaT,
216      affects some experiments at truncation level:
217      - global_ocean.cs32x15.icedyn (11 digits),
218      - global_ocean.cs32x15.seaice (11 digits),
219      - seaice_itd (12 digits), seaice_itd.lipscomb07 (12 digits) -> update
220      - also update global_ocean.cs32x15 adjoint and tangent-linear results
221    o pkg/salt_plume & pkg/thsice:
222      - for coupled  set-up with pkg/thsice in ATM and pkg/salt_plume in OCN,
223        connect salt_plume flux to ATM-OCN coupling pkgs interface:
224       a) in ATM: also cumulate salt-plume flux in S/R THSICE_SALT_PLUME (for
225         export to coupler interface) even without compiling pkg/salt_plume ;
226       b) in OCN: apply coupler salt-plume flux to pkg/salt_plume field
227         (saltPlumeFlux) just before exch call, in S/R SALT_PLUME_DO_EXCH.
228    o pkg/dic:
229      - use the updated seaice fraction (from seaice pkgs) for DIC forcing
230        instead of the previous time-step value ; done in new S/R DIC_FIELDS_UPDATE
231        called from the top of dic_biotic_forcing.F (instead of in DIC_FIELDS_LOAD);
232      - move also update with values from ATM-OCN Coupler in the same new S/R
233        (previously done in ocn_apply_import.F).
234    o tools/adjoint_options:
235      - specify explicitly "-f77" or "-f90" in default ad-optfile since TAF (default)
236        has been changed on Jan 14, 2016.
237    o pkg/ggl90:
238      - add alternative discretisation of vertical shear (off by default), to
239        compute the mean (@ grid-cell center) of vertical shear compon instead of
240        vertical shear of mean flow (@ grid-cell center).
241      - add correct parenthesis in ALLOW_GGL90_SMOOTH code to get the same truncated
242        results on adjacent faces of cubed-sphere grids; this fix the restart.
243    o pkg/atm_compon_interf:
244      - skip time-ave over cpl_atmSendFrq of Sea-Level Pressure (atmSLPr) and just
245        pass last value, stored directly before export to CPL ;
246        Note: this affects results of Coupled set-up where OCN uses useImportSLP=T
247      - remove atmSLPr from pickup files (no longer needed for restart)
248    
249    checkpoint65s (2016/01/13)
250    o eesupp & genmake2:
251       - first check for Function ETIME and, if it fails, then check for subroutine
252         ETIME and consistent output; use the appropriate version in timers.F
253    o model/src:
254      - to check restart test, add option to apply EXCH to U,V earlier, just before
255        integr_continuity; turned off by default.
256    o pkg/dic:
257      - remove CPP option USE_ATMOSCO2 (not needed)
258    o tools/tst_2+2:
259      - try to ignore difference between +0 and -0 in binary file, causing test
260        to fail for no good reason.
261    o eesupp & genmake2:
262      - put back modif from Jinxuan Zhu - change etime fct call to S/R call -
263        but also check (in genmake2) that test runs and returns meaningful results.
264    o coupler pkgs:
265      Finish implementation of optionally-exchanged variable switches (started on
266       Nov 12) with addition of few more exchanged fields, including 2-way exchange
267       of pkg/thsice vars to allow to use seaice dynamics (from pkg/seaice) & seaice
268       advection in OCN component; this requires sequential coupling.
269      coupler (pkg/atm_ocn_coupler):
270      - add argument msgUnit and iter number to CPL_SEND/RECV_ATM/OCN_FIELDS
271        routines (useful for debug).
272      - only export/import optionally exchanged fields (RunOff, seaice, Salt-Plume
273         flux, DIC fields) if corresponding switch is ON.
274      - add option to export RunOff to OCN (to use for DIC river input)
275      - add 2-way thSIce vars exchange; check for consistent cpl_sequential setting.
276      components (pkg/atm_ & ocn_compon_interf):
277      - to save memory space in ATM & OCN comp: add some #ifdef ALLOW_${PKG} around
278        optionally exchanged fields; add a check & stop in cpl_readparms.F.
279        ATMCPL.h: ALLOW_LAND for RunOff, ALLOW_THSICE for seaice, ALLOW_AIM for CO2;
280        OCNCPL.h: ALLOW_SALT_PLUME, ALLOW_DIC for DIC, ALLOW_THSICE for 2-W thsice.
281      - rename:   fracIce     -> sIceFrac_cpl (<- match coupler var name)
282        + in ATM: fracIceTime -> sIceFracTime ; seaIceTime -> sIceMassTime.
283      - add 2-way thSIce vars exchange ; add Salt-Plume flux ; add RunOff in OCN.
284      - hold in common block coupler optionally-exchanged variable switch
285        and set default "useImportXXX" accordingly; + check & stop if inconsistent.
286      - add diagnostics for all imported fields from coupler (in both OCN & ATM);
287        this is intended to replace the OCN cplFldtave.* output files (not updated
288        to contain new additional exchanged fields).
289    o pkg/dic:
290      - fix an other bug (also from 2014/08/30) in dic_atmos.F, in dic_int1=3 code.
291    o pkg/thsice:
292      - when coupled to ATM (useCoupler) with thSIce_skipThermo=T, skip reading
293        and writing of thsice pickup files.
294    o pkg/atm_compon_interf:
295      - move all field individual export-call out of cpl_export_import_data.F
296        into new S/R ATM_EXPORT_FIELDS
297    o pkg/atm_compon_interf:
298      - store state variables (for now, only thSIce fields) just before beeing
299        exported (in cpl_export_import_data.F, like on ocean side) instead of from
300        atm_store_my_data.F like all exported fluxes.
301      - new version of pickup_cpl: write field names into meta file and read meta
302        file to find field postion in pickup. Also only write/read fields meeded for
303        restart (same logic as main pickup file ; also using pickupStrictlyMatch)
304    o pkg/dic:
305      - fix bug (added on 2014/08/30) in dic_atmos.F for the case dic_int1= 2 or 3.
306    o pkg/seaice: add new parameter SEAICEpressReplFac to choose between
307        pressure replacement method (=1., default) or original Hibler (1979) (=0.)
308        value can be from domain [0,1] to average between the two methods
309    o pkg/atm_phys:
310      - allow to provide 2-d map of albedo and mixed-layer depth from files (but
311        hold fixed in time).
312    
313    checkpoint65r (2015/12/21)
314    o pkg/seaice:
315        fix bug in tridiagonal solvers for SEAICE_OLx/y>0, this affects the JFNK
316        solver (offline.dyn_jfnk) and global_ocean.cs32x15.seaice -> updated
317    o pkg/seaice:
318      - fix a bug in computing areaS in (J-J -> J-1) that affects runs
319        when SEAICEscaleSurfStress=.TRUE.,
320      - apply areaW and areaS in S/R seaice_calc_lhs
321    o pkg/atm_phys:
322      - add diagnostics for 3-D, Nr+1 levels diagnostics of radiative fluxes
323        (shortwave & longwave, net & downward) and diagnostics of temp. tendency
324        for individual contribution (convection, LSC cond, radiation)
325      - add Ruth Geen etal, GRL 2016, radiation options (see paper supp.
326        information); activated with: solar_exponent=0. and wv_exponent=-1.
327    o pkg/ggl90:
328      - within IDEMIX add upper limit for horizontal group velocity to
329        avoid instability problems in the explicit horizontal diffusion term for
330        long time steps or high resolution
331    o pkg/diagnostics:
332      - simplify setting of local-array size in diagstats_output.F: uses "numLevels"
333        (from DIAGNOSTICS_SIZE.h) to allow to write out more than Nr levels.
334    o testreport:
335      - remove "-v" (verbose option) in default mpirun command.
336    o pkg/seaice/seaice_growth:
337      - catch potential division by zero in ITD code, does not change
338        verification results
339    o pkg/ecco:
340      - retire old codes to the Attic. The calls to retired functions are
341        left in a commented form in case they ever need to be re-activated.
342      - ecco_check.F: issue warning if any old CPP option is
343        defined that corresponds to retired codes -- then stop.
344    o pkg/atm_compon_interf:
345      - change seaice fraction (use for OCN dic surf.flux) stored and sent to
346        coupler: use last time-step value instead of average over cplSendFrq_iter
347        time-step, similar to what is done for seaIceMass.
348        This will affect results (pkg/dic) of coupled ATM-OCN+dic set-up.
349    o eesupp & genmake2:
350      - from Jinxuan Zhu: change etime fct call to S/R call (fix gfortran ETIME);
351        <= remove until a fix is found for some ifort version on ia32 machine.
352    o pkg/seaice/seaice_evp:
353      - refine residual computation
354    
355    checkpoint65q (2015/11/18)
356    o pkg/seaice/seaice_evp:
357      - fix residual computations so that they no longer affect the actual
358        simulation code
359      - fix seaice_readparams to be able to actually set new parameters
360        SEAICEaEVPcStar and SEAICEaEVPalphaMin, also fix logic a little
361    o model/src:
362      - fix wrong truncation (single prec) from "FLOAT" function in expressions
363        like: deltaT*FLOAT(myIter) when myIter is large:
364         a) replaced by DFLOAT (if not seen by TAF);
365         b) remove "FLOAT" and use implicit type conversion (if seen by TAF).
366    o pkg/aim_v23:
367      - write/read the expected CO2 pickups (from S/R AIM_DO_CO2): fix reading
368        when pickupSuff is set ; do write rolling pickups + at the end of the run.
369    o pkg/atm_ocn_coupler + ocn_compon_interf:
370      - in prep for using pkg/seaice Dyn in coupled set-up, implement sequential
371        coupling option-1: ATM -(cpl)-> OCN and then OCN -(cpl)-> ATM ;
372        add corresponding call in DO_OCEANIC_PHYS.
373    o coupler pkgs:
374      Start a new way to set-up optionally-exchanged variables (previously, only
375       there for exchange_DIC): switch on/off from 1 place, at run-time, in coupler
376       data.cpl (new) instead of at compile time in ATMIDS.h & OCNIDS.h ;
377       send switch to ATM & OCN compon before reading their own "data.cpl" (so that
378       compononent param default can be set accordingly).
379      Note: this new switch (cpl_exchange_[xxx]) is not a per variable switch
380       but rather applies to a group a fields (going both ways like for DIC)
381       and corresponds to an option of coupling config.
382      coupler (pkg/atm_ocn_coupler):
383      - change parameter file from "data" to "data.cpl" (in cpl_read_params.F),
384        and read namelist directly (without eessup S/R calls) instead of
385        in the very un-flexible old way, 1 param per line, in fixed order;
386      - add error-counter to track errors (e.g., missing "data.cpl") and to stop
387        cleanly in CPL_CHECK_CPLCONFIG
388      - add new coupling-exchange selectors (some not yet active) including
389        cpl_exchange_DIC (to set to 3 to replace atmCpl_exchange_DIC=T in ATMIDS.h
390                                             and ocnCpl_exchange_DIC=T in OCNIDS.h);
391      - add 2 new S/R (CPL_SEND_ATM/OCN_CPLPARMS) to send coupler-params to each
392        component ; called directly from coupler.F, after comp. registrations;
393      - rename few variable-ID names (in ATMIDS.h & OCNIDS.h):
394         atm/ocnSeaIceName --> atm/ocnSIceMassName ; atm/ocnFCO2Name ->
395          -> atm/ocnCO2FluxName ; atm/ocnWSpdName --> atm/ocnWindSpdName
396      components (pkg/atm_ & ocn_compon_interf):
397      - add ATM/OCN_CPL_OPTIONS.h in component pkgs and include the corresponding
398        CPP header file in all pkg source files.
399      - move checking of comp. configs out of cpl_exch_configs.F into new S/R
400        ATM/OCN_CHECK_CPLCONFIG;
401      - add error-counter to track errors (e.g., in "data.cpl") and to stop
402        cleanly in ATM/OCN_CHECK_CPLCONFIG;
403      - add new S/R CPL_IMPORT_CPLPARMS to import coupling-exchange selectors
404        from coupler ; called from initialise_fixed.F, after PACKAGES_BOOT and
405        before PACKAGES_READPARMS;
406      verification/cpl_aim+ocn/:
407      - update ATMIDS.h & OCNIDS.h (in shared_code) and use new parameter file
408        "data.cpl" for coupler (in input_cpl).
409    o eesupp/inc:
410      - change the MPI-global-sum default (in CPP_EEOPTIONS.h) to:
411        #define GLOBAL_SUM_ORDER_TILES (only affects MPI built of global_sum_tile.F)
412        to always cumulate tile local-sum in the same order (still uses
413        MPI_Allreduce like standard code).
414      - in verification experiment code, remove local CPP_EEOPTIONS.h_mpi files
415        that are now identical to standard version (in eesupp/inc).
416    o pkg/shelfice:
417      - add SHELFICETransCoeffTFile for initializing spatially varying
418        heat and salt transfer coefficients
419    o pkg/atm_compon_interf & ocn_compon_interf:
420      - combine into 1 (new) S/R CPL_EXPORT_IMPORT_DATA the two previous
421        S/R CPL_EXPORT_MY_DATA & CPL_IMPORT_EXTERNAL_DATA
422      - move bi,bj loops inside S/R OCN_STORE_MY_DATA
423    o pkg/atm_ocn_coupler:
424      - initialise to zero ATMVARS.h & OCNVARS.h arrays.
425    o pkg/rbcs:
426      - select RBCS-mask for Temp & Salt the same way as for pTracer ; this allows
427        to compile with maskLEN=1 when all tracers use the same RBCS-mask.
428      - add a short report (to STDOUT) about RBCS-mask settings.
429    
430    checkpoint65p (2015/10/23)
431    o pkg/seaice/seaice_evp.F: fix store directives and key computations, since
432        there is no adjoint test for EVP, we don't know what it does to the adjoint
433        solution, but at least there are no more recomputation warnings left
434    o pkg/seaice/seaice_evp.F: slight modification of averaging so that EVP stands
435        a chance of giving the same results as a fully converged VP (JFNK) solver
436    o tools/adjoint_options/adjoint_diva:
437      - fix bug (typo) in Tang-Linear FLAGS setting for MPI + DIVA
438    o pkg/streamice:
439      - spotted bug in streamice_driving_stress using dyG where should have been dxG
440    o pkg/exf:
441      - remove STOP statement that prevented to use wind or (wind-)stress
442        interpolation for constant-in-time forcing fields (wind/stress period = 0).
443    o pkg/seaice:
444      - replace SEAICE_EVP_USE_ADAPTATION by run time parameters, requires
445        5 additionals 2D fields and 6 new store directives
446      - change logic in seaice_readparms.F: EVP code can now be turned on in
447        various ways, setting SEAICE_deltaTev is no longer required,
448        alternatively set SEAICE_evpAlpha/Beta, SEAICEuseEVPstar, SEAICEuseEVPrev,
449        or SEAICEaEVPcoeff
450    o pkg/shelfice/shelfice_thermodynamics.F
451      - redefining uLoc/vLoc to u/v, instead of 2u/v
452    o pkg/seaice/seaice_evp.F: introduce "adaptive EVP" by Madlen Kimmritz
453      - this is an intermediate state of a truely converging EVP that has
454        the potential of outperforming implicit VP methods, I do not recommend
455        using it yet.
456      - for now, "adaptive EVP" is turned on by setting SEAICE_EVP_USE_ADAPTATION
457        and all parameters are hardwired
458      - for convergence it still requires very smooth regularisations, that means,
459        if SEAICE_DELTA_SMOOTHREG is defined, deltaCreg=deltaC+deltaMin, which is
460        different from the VP case with deltaCreg=sqrt(deltaC**2+deltaMin**2); also
461        specific averaging appears to be required, still subject to tuning
462      - still needs cleaning and I need to turn parameter into runtime parameters
463      - add code to compute and print residuals of iteration, compile with
464        defining ALLOW_SEAICE_EVP_RESIDUAL to enable it
465    o pkg/seaice/seaice_evp.F: fix a bug (factor of four in front of e12Csq)
466      that entered with r1.54 on Sep04, 2015, -> update results
467    
468    checkpoint65o (2015/09/14)
469    o pkg/mom_vecinv & mom_common:
470      - add deep-atmosphere geometry factor in mom_calc_visc.F + in routines
471        called from there.
472      - add anelastic and deep-atmosphere geometry factor in pkg/mom_vecinv ; this
473        allows to use Vector-Invariant form in deep atmos and anelastic formulation
474    o pkg/seaice: introduce fast ice parameterisation following Itkin et al. (2015)
475      and Koenig-Beatty+Holland (2012)
476      - two new parameters SEAICE_tensilFac and SEAICE_tensilDepth
477      - global 2D field tensileStrength, computed in seaice_calc_ice_strength
478      - requires an extra input argument for S/R seaice_calc_viscosities
479      - tensileStrength's depth dependence is different from Itkin et al. (2015)
480        (to be changed and played with, for now exponential)
481    o pkg/seaice: introduce new parameter SEAICEscaleSurfStress (default = .FALSE.)
482      - if TRUE scale ice-ocean and ice-atmosphere stress acting on sea ice
483        by AREA according to Connelly et al. (2004), JPO.
484      - For EVP and the LSR solver, the implicit part of the drag term is
485        the only non-zero term in the denominator when there is no ice (which
486        prevented running the model with zero ice-ocean drag). If
487        SEAICEscaleSurfStress = .TRUE., this results in a division by zero
488        (or zero main diagonals BU/BV) which need to be caught. A practical
489        consequence is that for open water, the momentum equation reduce
490        to trivially 0 = 0 + 0 (for EVP). For LSR, BU/BV are reset to 1, if
491        they happen to be zero, often leading to a non-zero solution over
492        open water.
493    o pkg/seaice: revise EVP code (seaice_evp.F) in preparation for a more
494        efficient EVP method.
495      - introduce area-weighted averages for e12 (analogously to
496        seaice_calc_viscosities.F); this totally changes lab_sea.hb87 (2 digits
497        remain, but also changing the order of terms in the previous average
498        changed the results as much) -> update experiment
499      - add SEAICE_DELTA_SMOOTHREG code
500      - disentangle computation of zetaC/deltaC and zetaZ/deltaZ, also for
501        TEM-code
502      - adjust loop bounds so that only required fields are computed
503      - add new averaging code for zetaZ/deltaZ (again similar to
504        seaice_calc_viscosities.F), inactive by default for now (will change
505        results again), but will replace old code eventually
506    o eesupp/src:
507      - add an other alternative for multi-proc GLOBAL_SUM (in global_sum_tile.F)
508        to always cumulate tile local-sum in the same order
509        (option #define GLOBAL_SUM_ORDER_TILES in CPP_EEOPTIONS.h).
510        Still uses MPI_Allreduce (like standard code) but on array of tiles
511        and should be faster than GLOBAL_SUM_SEND_RECV code.
512      - switch almost all verification experiments that use GLOBAL_SUM_SEND_RECV
513        (defined in CPP_EEOPTIONS.h_mpi) to GLOBAL_SUM_ORDER_TILES instead.
514      - add CPP_EEOPTIONS.h_mpi with GLOBAL_SUM_ORDER_TILES defined in 14 more exp.:
515         aim.5l_cs, cheapAML_box, deep_anelastic, dome, fizhi-cs-32x32x40,
516         fizhi-cs-aqualev20, fizhi-gridalt-hs, global_ocean_ebm, matrix_example,
517         natl_box, solid-body.cs-32x32x1, tutorial_advection_in_gyre,
518         tutorial_baroclinic_gyre and tutorial_held_suarez_cs.
519    
520    checkpoint65n (2015/07/29)
521    o pkg/thsice:
522      - add a warning when used with pkg/aim but without updating SST
523        (stepFwd_oceMxL=F & useCoupler=F & tauRelax_MxL<>-1 ).
524    o pkg/offline:
525      - change where Offline-Fields are loaded, from load_fields_driver.F to
526        directly within FORWARD_STEP, just after updating iter number and time;
527      - move setting of GM and KPP diffusivity out of OFFLINE_FIELDS_LOAD into new
528        S/R OFFLINE_GET_DIFFUS that is called towards the end of DO_OCEANIC_PHYS;
529       These changes allow:
530        a) to recover exactly on-line results using deltaToffline=deltaTClock,
531        tested (using offlineIter0= nIter0 -1 and offlineTimeOffset= -deltaT/2)
532        both with Lin & Non-Lin Free-Surf, both with staggerTimeStep & synchronous
533        time-step, both with GM & KPP files and with recomputing these fields;
534        b) no needs to switch on staggerTimeStep anymore;
535        c) simplify rescaling of offline horiz. velocity with Non-Lin Free-Surf.
536      - update output of experiment tutorial_dic_adjoffline (only 3 digits left).
537    o pkg/offline:
538      - change (rarely used) offset-iteration parameter to an offset time (in s):
539        can easily recover previous offset-iter effect by setting offset-time
540        (offlineTimeOffset) to offset-iter x deltaToffline;
541      - do not turn-off Temp & Salinity surface relaxation when using KPP (used
542        in KPP as part of surface buoyancy forcing) in offline run.
543      - fix ptracers KPP non-local term in the case where KPP is re-computed.
544    o OpenAD
545      - Adding preliminary ggl90 test to OpenAD verification.
546        Config. with ggl90 currently diverges after 64 time steps
547        so will need more work to become more stable
548      - Adding preliminary kpp test to OpenAD verification.
549        required small tweakes in kpp_routines.F
550      - Merge and update from Krishna Narayanan's contrib area:
551        * Add one variable for preliminary OpenAD DIVA
552        * Add replacement time-stepping for OpenAD DIVA
553        * genmake2 flag -diva (but only for OpenAD; preliminary)
554        * required modifs for OAD_support
555        successful preliminary test for tutorial_global_oce_biogeo/
556    o pkg/seaice:
557      - initialise deltaC in seaice_lsr, cosmetic changes in seaice_lsr
558      - add cpp-flag SEAICE_DELTA_SMOOTHREG for option of regularising
559        delta with a smooth function in s/r seaice_calc_viscosity
560        (no effect on EVP)
561      - rename local suffix "sqr" into "sq" for more consistent variable names
562    o pkg/seaice:
563        add new parameter SEAICE_deltaMin that is used ***only***
564        for regularizing Delta (and nothing else, like the parameter
565        which is also used for all sorts of things SEAICE_EPS).
566        Defaults to SEAICE_EPS for backward compatibility only.
567    o pkg/seaice: replace erroneously storing e12Csqr on the wrong tape with
568        the wrong key by inialising it before use -> fixes a recomputation
569        problem but does not fix the gradient
570    o pkg/layers:
571      - move resetting of flux arrays to outside the iLa loop
572        (this caused layers_diapycnal to not work with more than one layer coord.)
573      - fix bug in calculation of layers_recip_delta in layers_init_fixed.F
574    o pkg/layers:
575      - remove from common block 3D layers fields (used to diagnose transport
576        in tracer coords) and declare them as local arrays in layers_calc.F
577    o pkg/seaice:
578      - Rename SEAICE_VECTORIZE_LSR_ZEBRA to SEAICE_LSR_ZEBRA and define it
579        in lab_sea forward experiment (changes results -> updated)
580      - update adjoint experiment lab_sea after cleaning up seaice_lsr_tridiagu/v
581    o pkg/seaice: modify seaice_lsr.F in order to improve the gradient
582       computations; for SEAICE_VECTORIZE_LSR
583      - move the loops over which the tridiagonal solvers (seaice_lsr_tridiagu/v)
584        sweep to the outside,
585      - remove store directives and add "CADJ loop sequential" directives
586        in analogy to model/src/solve_tridiagonal.F
587      - replace many "#ifdef SEAICE_VECTORIZE_LSR_ZEBRA" by variable loop
588        boundaries to yield more readable code. This has also the charming side
589        effect that your can use SEAICE_VECTORIZE_LSR_ZEBRA without
590        SEAICE_VECTORIZE_LSR (i.e. adjoint without recomputations in
591        seaice_lsr_tridiagu/v now requires either of these flags, vectorization
592        still requires SEAICE_VECTORIZE_LSR with SEAICE_VECTORIZE_LSR_ZEBRA as
593        an additional option)
594       The tridiagonal solvers are now completely analoguous to solve_tridiagonal.F
595       but the adjoint gradients (which are affected by this change) still explode.
596    o coupler (atm & ocn _compon_interf):
597      - avoid using Exch2 IO mapping if not suitable.
598    
599    checkpoint65m (2015/06/15)
600    o pkg/layers:
601      - clean-up old parameters setting (from Sep 2012):
602        + remove old parameters setting from common block (declared locally);
603        + stop if any old parameter is mixed with new parameters;
604        + check for valid or consistent parameter setting (e.g., layers_name)
605      - check that layers_bounds for Pot.Density are in the right range;
606        this is supposed to catch un-updated setting after recently shifting
607        potential density field "prho" by -1000 (now in "sigma" scale).
608    o pkg/layers:
609      - Added missing call to layers_fill for keeping track of tottend in
610        pkg/diagnostics/diagnostics_fill_state.F
611    o pkg/layers:
612      - added CPP flux LAYERS_FINEGRID_DIAPYCNAL to disable fine-grid binning
613        of diapycnal fluxes
614    o pkg/layers:
615      - reverted changes to interpolation to previous treatment; there
616        was never actually a problem
617    o pkg/layers:
618      - fix interpolation of layers tracers in the presence of partial cells
619      - add lots of new functionality to compute water mass transformation
620        (enabled by CPP flag LAYERS_THERMODYNAMICS)
621      - add new calls from main code (diags_oceanic_surf_flux.F,
622        thermodynamics.F, impldiff.F) and gad to save the necessary fields
623        for layers_thermodynamics calculations
624    o pkg/ptracers:
625      - add capability of stepping a passive tracer forward without advection
626        by setting PTRACERS_advScheme to 0.
627    o pkg/diagnostics:
628      - add few (threads) _BARRIER around any update of "diag_pkgStatus".
629    o pkg/layers:
630      - shift potential density field "prho" by -1000 for density layer averaging so
631        that it corresponds to usual "sigma" definition (i.e., rho(p=const)-1000);
632        Note that density bin boundaries (layers_bounds in data.layers) have
633        to be set accordingly (i.e., shifted, in sigma scale).
634    o pkg/layers:
635      - fix snap-shot output of layer thickness @ V.pt and output of pot.density
636      - fix calculation of layer non-weighted velocity and layer probability
637      - add diagnostics for pot.density used for layer averaging
638    o pkg/seaice:
639      - seaice_calc_viscosity.F: change computation of deltaC**2 to ensure
640        positiveness, modify a few comments and improve variable names,
641      - the changed computation of deltaC affects most seaice-related
642        experiments at the truncation level.
643        seaice_itd.thermo is affected by far the most, with
644        only 7 digits of agreement remaining; update experiments.
645    
646    checkpoint65l (2015/05/04)
647    o pkg/shelfice:
648      - in shelfice_thermodynamics.F, if SHELFICEBoundaryLayer=.true., then set
649        factor drKp1 to zero where it is negative (ie. do not use
650        SHELFICEBoundaryLayer if hFacC>1)
651      - the same for factor drLoc in shelfice_forcing.F
652    o tools/genmake2: move FEXTRAFLAGS from FFLAGS to FOPTIM to avoid a problem
653        with modules in ptracers, when using testreport option "-small_f"
654    o pkg/seaice/seaice_growth.F (in case of SEAICE_ITD)
655      - replace tmpscal1**1.36 by faster exp(1.36*log(tmpscal1))
656    o verification/testreport
657      - add new option -small_f
658        with this option testreport first makes the target small_f (*.f files)
659        before running make (all). This is useful for explicit inlining when
660        all sources need to be full available.
661    o pkg/exf/exf_interp.F:
662        remove previous changes related to reverse (decreasing) input grids latitude
663    
664    checkpoint65k (2015/04/01)
665    o pkg/ecco:
666        fix missing cosphi initialization; use eccoiter in place of optimcycle;
667        if autodiff is not compiled then use READ_REC_XY_RL/READ_REC_XYZ_RL
668        instead of active read/write
669    o pkg/ctrl:
670        if autodiff is not compiled then use READ_REC_XY_RL/READ_REC_XYZ_RL
671        instead of active read/write.
672    o pkg/autodiff: make autodiff_readparms.F and autodiff_whtapeio_sync.F
673        return if .NOT.useAUTODIFF
674    o pkg/seaice: add CPP brackets (cost function related).
675    o model/src:
676        add useAUTODIFF run time switch.
677    o pkg/exf/exf_interp.F:
678        add code to allow input grids with latitude starting in the north (i.e. when
679        j=1 corresponds to northern edge of field); modify global_with_exf to test
680        this feature.
681    o verification/testreport:
682      - replace "grep -A3" with POSIX conformal sed command, because there are
683        implementations of grep that cannot do contextual searches
684      - replace "cat -n" by "nl" (two occurrences), because not all implementations
685        of "cat" have the option "-n"
686    o model/src:
687        add new file gsw_teos10.F that contains 3 functions, more or less a copy
688        of the gsw_toolbox.f90 of the TEOS-10 fortran interface, that are used to
689        convert from conservative to potential temperature. For now they are not
690        called anywhere.
691    o pkg/ggl90: make "useIDEMIX" useful
692      - re-organize code in s/r ggl90_calc a little to move computations that
693        are different for idemix into separate loops (changes verification
694        experiment idemix at truncation level, 12 digits remain -> updated)
695      - requires 2 new 2D fields KappaM, verticalShear
696      - make hFacI and recip_hFacI local 3D variables that are passed to
697        s/r ggl90_idemix
698      - fix and improve some comments
699    
700    checkpoint65j (2015/02/25)
701    o pkg/openad
702      - synchronize seawater.F with version in model/src: replace routine
703        body of sw_temp by calling sw_ptmp and fix/add a few comments.
704    o pkg/mnc:
705      - change default value of pickup_read/write_mnc params to FALSE
706        (since few features are missing in reading MNC pickup files).
707    o model/src:
708      - change default (background) vertical diffusivity for salt to be the
709        temperature (background) vertical diffusivity.
710      - change background vertical diffusivity in vertical mixing pkgs ggl90,
711        kl10, my82 and pp81 from temperature diffusivity to salinity diffusivity.
712        This makes ptracers default diffusivity (that uses salt diffKr) more
713        consistent with vertical mixing schemes.
714    o verification/testreport:
715      - fix typo in "-pcls" option ;
716      - put temp files in /tmp (instead of in local dir)
717      - add option "-ncad" to use genmake2 new option "-nocat4ad"
718      - allow to use "-j" option (for multi-procs make) for AD, OAD and TLM.
719    o pkg/ggl90 (idemix code):
720      - apply few fixes ; add some missing "_d 0" ; update output of exp.
721        global_ocean.90x40x15.idemix
722    o OpenAD
723      - enable active file I/O and begin removal of work-around code
724        for OpenAD for handling control variables (memory vs. active files)
725      - new CPP options file OPENAD_OPTIONS.h
726      - revert to genarr2d gradient check for hs94.1x64x5
727      - (genarr3d tested by tutorial_global_oce_biogeo, tutorial_tracer_adjsens)
728      - gentim2d works for halfpipe_streamice but not yet hs94.1x64x5
729    o tools/genmake2:
730      - add option for an alternative Makefile (from Martin) where multiple
731        source files are sent to TAF (instead of all in one file).
732    o pkg/ggl90: add IDEMIX (Olbers and Eden, 2013)
733      - code provided by Carsten Eden as an extension of ggl90
734      - so far the code is turned on within ggl90 by setting a CPP-flag at
735        compile time; a runtime flag implementation is not yet complete
736      - tested in new verification experiment global_ocean.90x40x15.idemix
737    o verification:
738      - reduce length of the AD test run by half for experiments
739        global_ocean.cs32x15 (std + thsice) and isomip
740      - enable active file I/O for OpenAD, adjust verifications accordingly
741      - halfpipe_streamice: change gradient check from genarr2d to gentim2d
742    o verification/testreport:
743      - fix two non-POSIX sed statements so that there are no error messages
744        on Mac OS X
745      - replace hostname -s with hostname | sed 's/\..*$//'
746    o model/src/seawater.F:
747      - simplify SW_TEMP to just calling SW_PTMP with P and PR exchanged
748        (following the matlab code), which would have avoided the bug caught
749        by Matt (see below) in the first place
750    o pkg/shelfice:
751      - implement alternative discretisation of quadratic drag (selectBotDragQuadr)
752        and true distance in no-slip BC (bottomVisc_pCell) similar to bottom-drag.
753      - fix sign of friction tendency (no-slip BC) and fix u,v drag for thin
754        ice-shelf case (i.e., within surface level).
755      - add config summary in shelfice_check.F
756      - remove global variable recip_SHELFICElatentHeat and replace by a local
757        variable recip_latentHeat
758      - introduce diagnostics for friction velocity uStar (in case of
759        SHELFICEuseGammaFrict)
760      - change verification experiment isomip.htd:
761        + start from pickup (as input_ad at nIter0=8640)
762        + start from SHELFICEmassFile instead of SHELFICEloadAnomaly file
763        + test SHELFICEuseGammaFrict = .TRUE.
764        + test SHELFICEadvDiffHeatFlux = .TRUE.
765    o model/src:
766      - fix bug (Thanks to Matt) in function SW_TEMP (to convert Pot.Temp to
767        in-situ Temp) and in routine SW_TEMP (in pkg/openad);
768        update output of experiments global_with_exf.yearly and isomip (all 6).
769    o pkg/shelfice:
770      - change setting of kTopC to also be zero where there is no ice-shelf.
771      - zero out surface forcing arrays (for now, for T & S + EmPmR) where
772        ice-shelf is.
773      - first attempt to get RealFreshWaterFlux effects: for now, only without
774        SHELFICEboundaryLayer ; not consistent if using synchronous time-stepping.
775    o pkg/seaice: add the option to prescribe a fixed thickness PDF
776      for thermodynamic calculations
777      - because of divisions of the type 7/7 not exactly equal to 1, this change
778        affects results of some verification experiments by up to 4 digits:
779        global_ocean.cs32x15.seaice, lab_sea, lab_sea.fd, lab_sea.salt_plume,
780        seaice_obcs, seaice_obcs.seaiceSponge, seaice_obcs.tides
781        adjoint: lab_sea, lab_sea.noseaicedyn
782        -> updated
783    
784    checkpoint65i (2015/01/23)
785    o model/src:
786      - change units of frictionHeating field from W to W/m^2
787      - fix bug in frictional heating from stratospheric drag in
788        S/R ATM_PHYS_TENDENCY_APPLY_V
789      - with synchronous time-stepping: move resetting to zero of frictionHeating
790        field from load_fields_driver.F to thermodynamics.F ;
791      - add diagnostics for frictional heating.
792    o model/src & gmredi K3D:
793      - add frictionHeating field to pickup-files (for synchronous time-stepping)
794      - move ALLOW_EDDYPSI block out of DYNVARS.h and merge it into FFIELDS.h
795      - rename uMean,vMean --> uEulerMean,vEulerMean (+ change diagnostics name
796        and name in pickup file).
797      - fix arguments of few DIAGNOSTICS_FILL calls in gmredi_k3d.F
798    o model/src:
799      - move (from ini_forcing.F) initialisation of all arrays in header file
800        FFIELDS.h into new S/R ini_ffields.F ; this fix broken restart
801        (since Nov 2012) with option selectAddFluid=1.
802    o pkg/shelfice:
803      - change units (+ document) of newly added field "shelfIceMassDynTendency"
804      - upgrade from _RS to _RL shelficeMass & shelficeLoadAnomaly arrays.
805    o pkg/obcs: re-organize obcs_calc_stevens.F to prepare for passive tracers
806    o pkg/seaice: two new runtime parameters:
807      - SEAICE_cStar replaces the hard wired "20" in the strength formulation,
808        long overdue
809      - SEAICE_tensilFac: preparation for Koenig-Beatty+Holland (2012)
810        parameterization of tensil stress for fast ice (does not do anything yet)
811    o pkg/seaice/seaice_check.F: left over from restricted addtive Schwarz method
812        for LSR: move checking overlaps out of JFNK-if-block
813    o pkg/atm_phys:
814      - move copy of grid and dynamical fields out of atm_phys_driver.F into
815        new S/R ATM_PHYS_DYN2PHYS.
816      - fix level height for Linear Free-Surf case (to be consistent with
817        fixed-in-time pressure levels).
818    o pkg/mom_common (bottomdrag):
819      - average bottomDragFld (ALLOW_BOTTOMDRAG_CONTROL) from grid-cell center
820        to correct location (U & V point) in S/R MOM_U/V_BOTTOMDRAG;
821        update output (adm & tlm) of experiment global_ocean.90x40x15.bottomdrag.
822    o pkg/shelfice (u/v_drag):
823      - add one argument (the other velocity component) to S/R SHELFICE_U/V_DRAG;
824      - use SHELFICEDragLinear & SHELFICEDragQuadratic in shelfice_v_drag.F
825        (now similar to shelfice_u_drag.F)
826      - remove condition on bottomDragTerms when calling SHELFICE_U/V_DRAG
827        from mom_vecinv.F (similar to mom_fluxform calls).
828    o pkg/mom_common (bottomdrag):
829      - add one argument (the other velocity component) to S/R MOM_U/V_BOTTOMDRAG;
830      - add options for alternative discretisation of velocity norm in quadratic
831        bottom drag: averaging of grid-cell-center KE to U.point and V.point
832        (selectBotDragQuadr=0, original code) can produce noisy patterns; this
833        improves when averaging only the other component (e.g. vVel for U bottom
834        drag) using wet-point method (selectBotDragQuadr=2) or not (=1).
835      - add options (bottomVisc_pCell) to account for partial-cell in bottom
836        friction (no-slip BC) thus getting the true distance from the bottom;
837        off by default since this also reduces model stability (explicit bottom
838        friction). Changes produce different machine truncation with linear-drag
839        + no-slip BC: update output of experiments exp4.stevens (10 digits) and
840        front_relax (bvp & mxl, 10 & 11 digits).
841    o model/src & mom pkgs:
842      - add one more level to vertical viscosity local arrays (Nr+1, previously Nr)
843        since no-slip bottom BC uses viscosity @ k+1 to update velocity @ level k
844      - for now and until vertical mixing scheme are updated to fill up level Nr+1,
845        just copy level Nr value to level Nr+1.
846    o doc:
847      - add notes form Abhisek Chakraborty on how to close Heat & Salt budgets.
848    o pkg/shelfice:
849      - shelfice_init_varia.F, shelfice_init_fixed.F, shelfice_readparms.F,
850        SHELFICE.h: move array shelficemass to init_varia, initialise
851        from array shelficemassinit, which is set in init_fixed and
852        has option to be set from file; introduce array
853        shelficeMassDynTend array, set thru file in init_fixed
854      - NEW FILE: shelfice_step_icemass.F: update shelficemass from either
855        shelfIceFreshWaterFlux and shelficeMassDynTend or H_streamice in
856        pkg/streamice
857      - shelfice_thermodynamics.F: call shelfice_step_icemass if
858        SHELFICEMassStepping = .true.
859      - shelfice_ad_diff.list: add new subroutine shelfice_step_icemass.f
860    
861    checkpoint65h (2014/12/17)
862    o verification/global_ocean.90x40x15, global_ocean_ebm:
863      - update to generic controls.
864    o pkg/ctrl:
865      - ctrl_map_ini_genarr.F: test for igen>0
866      - ctrl_init_variables.F: add call to CTRL_MAP_INI_GENTIM2D.
867      - move gentim2d part of ctrl_map_ini_genarr.F to
868        new separate routine : ctrl_map_ini_gentim2d.F
869      - ctrl_cost_driver.F,ctrl_init.F ctrl_map_ini_genarr.F:
870        add time variable weights and cyclic controls (time mean,
871        seasonal cycle, etc) capabilities to gentim2d
872    o pkg/ecco:
873      - move reading of error, conversion to weights from
874        ecco_cost_init_fixed.F to ecco_toolbox.F (ecco_readwei)
875    o global_oce_llc90, cs32:
876      - activte sbo.
877      - CTRL_SIZE.h : add maxCtrlProc.
878      - activate the new genctrl capabilities.
879      - update following reorganization of global_oce_input_fields.tar.gz  
880    o pkg/ctrl/ctrl_ad_diff.list:
881      - add missing ctrl_init_rec.f
882    o tools/OAD_support/keepOriginal:
883      - add ctrl_init_rec.F
884    o model/src/the_main_loop.F, pkg/ctrl/ctrl_map_ini_genarr.F:
885      - avoid recomputations of xx_gentim2d_dummy.
886    o momentum diagnostics:
887      - move filling of diagnostics Um_Diss & Vm_Diss from mom_fluxform.F and
888        mom_vecinv.F to timestep.F (to include Smag-3D contribution).
889    o pkg/seaice/seaice_lsr.F:
890      - fix computation of BU/BV, make sure they are non-zero, only necessary
891        for cubed sphere exchanges and SEAICE_OLx/y>0.
892        This makes calling s/r fill_cs_corner_rl obsolete (removed).
893    o verification/global_ocean.cs32x15/input.seaice
894      - add test for strong implicit coupling and restricted addtive Schwarz
895        methods for LSR
896      - update results/output.seaice.txt
897    o verification/tutorial_global_oce_biogeo:
898      - AD & OAD set-up: switch off ALLOW_OLD_VIRTUALFLUX (like in fwd set-up)
899        and set PTRACERS_EvPrRn(1,2) to zero (for DIC & ALK);
900        update output_adm,_oadm,_tlm.txt
901    o pkg/dic:
902      - change default to "#undef ALLOW_OLD_VIRTUALFLUX" in DIC_OPTIONS.h
903      - add a stop when ALLOW_OLD_VIRTUALFLUX is defined and PTRACERS_EvPrRn
904        for tracer 1 & 2 is set (to avoid double counting of dilution effect).
905    o verification/tutorial_global_oce_biogeo:
906      - AD & OAD set-up: do not set PTRACERS_EvPrRn for tracer 1 & 2 since
907        dilution is already added by pkg/dic ALLOW_OLD_VIRTUALFLUX ;
908        update output_adm,_oadm,_tlm.txt
909    o eesupp/src:
910      - add fill_cs_corner_rl.F (_RL-copy of fill_cs_corner_rs.F)
911        and call it in seaice_lsr when using nonzero SEAICE_OLx/y
912    o pkg/seaice: introduce strongly implicit coupling, intended for stabilizing
913      LSR (following Hutchings et al. 2004)
914      - introduce zetaZ as a global variable (requires adjustments in
915        seaice_evp.F and seaice_jfnk.F) and compute analoguously to etaZ
916        in seaice_calc_viscosities.F
917      - new flag SEAICEuseStrImpCpl (default off)
918      - add new terms zetaZ*du/dy and zetaZ*dv/dx on both sides of the
919        momentum equations
920      - JFNK-solver (preconditioner) adjusted to allow using this method
921        (where it does not have any positive effect)
922    o pkg/seaice
923      - add overlap for restrictive additive Schwartz method also to LSR, but
924        turn it off by default (because it only seems to work for non-cubed
925        sphere/llc topologies)
926    o pkg/autodiff
927      - add extra exchanges in addummy_in_steppging also for mnc output
928    o pkg/seaice:
929      - add extra exchanges before dumping adjoint fields in seaice_ad_dump.F
930        to avoid stripes in the adjoint output (similar to addummy_in_stepping.F)
931    o pkg/obcs:
932      - add option to specify domain-connected piece Id along OB though files
933        (for now, only used to diagnose PhiVel; default =1 -> global correction)
934      - modify obcs_diag_balance.F to process each connected-part separately;
935        exclude OB where Id = 0 but keep the full divergence there (-> constant
936        Psi along this portion of OB and all inflow derived from grad(Phi))
937      - add example of OB-conect files in verification/so_box_biogeo/input.
938    o pkg/diagnostics:
939      - improve treatment of Open-Boundaries in Velocity-Potential calculation:
940      a) use non zero matrix element across OB and solve for Phi 1 grid point
941         outside OB (i.e, where tracer OBCS are applied).
942      b) global imbalance of inFlow/outFlow across OB: instead of modifying
943         velocity across OB, spread it uniformly along the OB in the RHS.
944    
945    checkpoint65g (2014/11/19)
946    o pkg/diagnostcis:
947      - add preconditioner off-diagonal factor (diagCG_pcOffDFac) as run-time param
948    o pkg/my82,pp81,kl10:
949      - fix ALLOW_3D_DIFFKR implementation (previously had no effect): use 3-D
950        field diffKr as background diffusivity to set minimum diffusivity value.
951    o pkg/seaice:
952      - add new parameter SEAICEuseEVPrev (for revisited EVP by
953        Bouillon et al 2013)
954      - add SEAICE_evpAlpha/Beta to namelist
955      - modify seaice_evp code to able to use SEAICEuseEVPrev. These changes
956        involve trivial re-ordering of divisions/multiplications that should not
957        have any effects, but ... they do change the results of lab_sea.hb87 so
958        that only 2 digits of agreement remain, in line with the general
959        instability/fragility of the evp-code. For now, I do not care and just
960        update the verification experiment
961    o pkg/ctrl : add generic pre-processing (xx_genarr2d_preproc etc)
962      - remove xx_genarr2d_numsmooth etc
963      - use xx_genarr2d_preproc etc instead
964      - carry out smooth_correl2D at initialization stage rather than during
965        time stepping.
966      - get smoothOpNb from xx_gentim2d_preproc
967    o global_oce_cs32 :
968      - add test of generic ecco capabilities.
969    o pkg/exf/exf_getsurfacefluxes.F :
970      - add to tmpUE/tmpVN rather than re-initializing them (conventional behavior).
971    o pkg/ctrl,ecco :
972      - omit un-necessary arguments to ctrl_cost_gen.F unless ECCO_CTRL_DEPRECATED
973        is defined.
974    o pkg/seaice: add diagnostics for Delta (deformation parameter)
975    o model/src:
976      - when ALLOW_3D_DIFFKR is defined, add a Warning if any of the vertical
977        diffusivity (background) is specified but ignored.
978    o verification:
979      - in testreport, convert hostname to lower case for default output dir name
980    o model, pkg : add useCTRL, useECCO parameters (on/off run time switch).
981    o pkg/dic: add modifications from Hajoon:
982      - add iron sedimentation flux function of the flux of PO4 out of bottom layer
983      - light attenuation: add self-shading effect by climatological Chlorophyll
984        (read from file).
985    o pkg/seaice/seaice_preconditioner.F : fix cpp flags, so that code also
986        compiles when SEAICE_ALLOW_DYNAMICS is undefined
987    o global_oce_llc90,cs32 : ecco_v4 verification exps now use separate
988        AUTODIFF_OPTIONS.h, CTRL_OPTIONS.h, ECCO_OPTIONS.h rather than
989        ECCO_CPPOPTIONS.h (i.e. replacing the deprecated, circumvoluted,
990        approach where CPP_OPTIONS.h includes an omnipotent
991        ECCO_CPPOPTIONS.h that superseeds pkgs '_OPTIONS.h').
992    o pkg/ctrl/ctrl_map_ini_genarr.F : include GMREDI_OPTIONS.h where
993        ALLOW_3D_KAPGM, ALLOW_3D_KAPREDI (to be added later) belong.
994    o pkg/seaice/SEAICE_SIZE.h : replace ALLOW_AUTODIFF_TAMC with ALLOW_AUTODIFF
995        to avoid needing AUTODIFF_OPTIONS.h anytime SEAICE_SIZE.h is included
996        (it seems that THSICE_SIZE.h, PTRACERS_SIZE.h have the same issue...)
997    o model/src, pkg/smooth, profiles, salt_plume, seaice, exf, ecco, ctrl :
998      add ECCO_OPTIONS.h, AUTODIFF_OPTIONS.h, CTRL_OPTIONS.h when needed
999      - ECCO_OPTIONS.h is needed when including ecco_cost.h, ecco.h
1000      - AUTODIFF_OPTIONS.h is needed when including tamc.h, tamc_keys.h
1001      - CTRL_OPTIONS.h is needed when including ctrl.h, optim.h, etc
1002    o pkg/ctrl,ecco,exf :
1003      - remove variables associated with NON-generic costs,
1004        unless ECCO_CTRL_DEPRECATED is defined.
1005      - remove NON-generic NON-obcs controls,
1006        unless ECCO_CTRL_DEPRECATED is defined.
1007    o pkg/ctrl : added ctrl_local_params.h
1008    o pkg/ecco : added ecco_local_params.h
1009    o verification : added ECCO_CTRL_DEPRECATED to most as and oad
1010        experiments, which will progressively be removed once the
1011        experiments are revised to use only generic controls/costs.
1012    
1013    checkpoint65f (2014/10/13)
1014    o pkg/ctrl, ecco, seaice : minor changes in headers
1015    o global_oce_llc90,cs32 : ecco_v4 verification exps now test generic
1016        cost function and control capabilities added since checkpoint65c.
1017    o pkg/ctrl: regroup all obcs ctrl variables in CTRL_OBCS.h.
1018    o pkg/ecco: increase modularity and improve logic
1019      - ecco_toolbox.F (new) : basic operations that are often used,
1020        including ecco_zero, ecco_cp, ecco_cprsrl, ecco_diffmsk,
1021        ecco_addcost, ecco_add, ecco_div, ecco_readbar.
1022      - cost_gencal.F (new) : determine filnames and records.
1023      - cost_genread.F, cost_generic.F : condense code using ecco_toolbox.
1024      - cost_generic.F : use spzeroloc rather than hard-coded -9999,
1025        and exploit the above functions leading to more compact code.
1026      - cost_genread.F : rm un-necessary arguments, re-arrange args order.
1027      - ecco_check.F, ecco_readparms.F : bring logic up to date (using_tpj,
1028        using_ers, using_gfo, using_mdt is now only defined within gencost)
1029    o pkg/ecco: extend generic cost capabilities
1030      - pkg/ecco : added 3D gencost (ALLOW_GENCOST3D), added gencost
1031        capabilities via gencost_preproc (+ _c,_i,_r related params),
1032        gencost_posproc (+ _c,_i,_r related params), gencost_nrecperiod,
1033        gencost_outputlevel arguments to cost_generic
1034      - pkg/ecco/cost_genread.F (new) : interface between cost_generic
1035        and active_read, making room for gencost_preproc to take effect.
1036        Added preproc code ('climmon') to replace GENERIC_BAR_MONTH.
1037      - pkg/ecco/cost_generic.F :
1038        compute and store misfit maks*(model-data) in localdif that is
1039        then used in cost and for output, output misfit if outlev.GT.0
1040      - pkg/ecco/cost_averagesfields.F : depend on gencost_barskip
1041        rather gencost_barfile for deciding whether to write barfile
1042      - pkg/ecco/ecco_cost_driver.F : extract call to cost_profiles from cost_hyd
1043      - pkg/ecco/ecco_cost_init_fixed.F : extract gencost weights from
1044        ecco_cost_weights, re-activate ecco_summary, determine gencost_barskip
1045      - pkg/ecco/ecco_summary.F : report gencost variables
1046      - pkg/ecco/cost_gencost_customize.F : treat case of scatterometer costs
1047    o pkg/sea/SEAICE_OPTIONS.h : add ALLOW_COST_ICE, ALLOW_SEAICE_COST_SMR_AREA
1048    o pkg/ecco: internal re-organization
1049      - resolve un-necessary dependancies within pkg/ecco and to pkg/ctrl
1050        (rm includes of optim.h and ctrl.h, replace optimcycle with eccoiter,
1051        mv relevant variables definition from ecco_cost.h to ecco.h,
1052        make sure gencost routines only include ecco.h)
1053      - throughout : add missing CCP switches, rm unused variables,
1054        and rm un-necessary CPP switches
1055      - throughout gencost routines : replace modelstartdate with
1056        gencost_startdate when needed
1057      - cost_bp_read.F : use arguments, instead of common blocs
1058        so that it can be used also by (new) cost_gencost_bpv4.F
1059      - ecco_init_varia.F : initialize RHOsumGlob_0, VOLsumGlob_0
1060      - ecco_phys.F : compute etanFull
1061      - ecco_readparms.F : rename using_topex as using_tpj, add
1062        bpv4-grace to gencost list, initialize added parameters
1063      - ecco_summary.F : include SIZE.h needed for augmented ecco.h
1064    
1065    checkpoint65e (2014/09/28)
1066    o pkg/obcs:
1067      - replaced the just-added CPP options with run-time variables
1068        (see pkg/obcs/OBCS_PARAMS.h for details)
1069    o pkg/obcs:
1070      - add additional CPP options for sponge boundary layers
1071        (see pkg/obcs/OBCS_OPTIONS.h for details)
1072    o pkg/atm_phys:
1073      - implement simple (obliquity only, assuming circular planet orbit)
1074        seasonal cycle for incoming insolation ; used when run-time parameter
1075        "select_incSW" is set to 1 ; by default (=0), uses old unchanged formula.
1076    o pkg/exf, pkg/ecco, pkg/ctrl:
1077      - add ctrlUseGen and .NOT.ctrlUseGen exclusive brackets
1078      - activate gentim2d for xx_atemp,xx_aqh,xx_swdown,xx_lwdown,xx_precip
1079      - implement gentim2d for xx_tauu, xx_tauv
1080    o pkg/ctrl, pkg/ecco :
1081      - fix and complement the generic controls implementation
1082    o pkg/exf/exf_getclim.F, exf_getffields.F, exf_getsurfacefluxes.F,
1083        pkg/shelfice/shelfice_thermodynamics.F,
1084        verification/hs94.1x64x5/code_ad/ctrl_map_gentim2d.F,
1085        verification/hs94.1x64x5/code_oad/ctrl_map_gentim2d.F :
1086      - add weight in CTRL_GET_GEN calls
1087    o pkg/ctrl :
1088      - ctrl_get_gen.F : add weight as input parameter, and apply
1089        it directly rather than using smooth_correl2Dw (to be retired).
1090      - ctrl_map_gentim2d.F : add wgentim2d in CTRL_GET_GEN call
1091    o pkg/ctrl :
1092      - introduce run time switch ctrlUseGen (in ctrl.h, ctrl_check.F,
1093        ctrl_init_variables.F, ctrl_readparms.F, ctrl_summary.F)
1094      - re-activate ctrl_summary (call in ctrl_init.F)

1102    
1103    checkpoint65d (2014/09/15)
1104    o pkg/ctrl/CTRL_GENARR.h, ctrl_readparms.F :
1105      - add xx_genarr2d_bounds,xx_genarr3d_bounds,
1106        xx_genarr2d_numsmooth, xx_genarr3d_numsmooth
1107    o pkg/ctrl/ctrl_map_ini_genarr.F :
1108      - remove compilation failure
1109      - replace hard coded example
1110      - use ctrl_map_ini_gen2D, 3D
1111    o pkg/ctrl/ctrl_pack.F, ctrl_unpack.F :
1112      - on/off switch based upon xx_genarr2d_weight,3d
1113    o src/packages_init_variables.F :
1114      - regroup pkg/estimation calls
1115      - remove CTRL_MAP_INI, CTRL_MAP_INI_ECCO
1116        (moved to ctrl_init_variables)

1128      - remove seaice_ctrl_map_ini (mv to ctrl_init_variables)
1129    o ecco/ecco_ad_diff.list :
1130      - add ecco_init_varia.f
1131    o ecco/ecco_init_varia.F
1132      - new routine
1133    o pkg/streamice:
1134      - move call to STREAMICE_INITIALIZE_PETSC from the_model_main.F
1135        to streamice_init_fixed.F ; fix setting of STREAMICEisOn.
1136      - from model/src, only call pkg/streamice routines if useStreamIce is TRUE.
1137    o pkg/generic_advdiff:
1138      - fix bug causing negatives in GAD_SMOLARKIEWICZ_HACK, introduced 8/8/2014.
1139    o pkg/exf:
1140      - exf_getffields.F : add xxg_atemp, xxg_aqh, xxg_swdown, xxg_lwdown,
1141         xxg_precip capability
1142      - exf_wind.F : no need for ALLOW_WSPEED_CONTROL cpp switch
1143    o pkg/ctrl:
1144      - ctrl_pack.F, ctrl_unpack.F : omit (un)packing of undefined xx_gentim2d
1145    o model/src/load_fields_driver.F :
1146      - move call to CTRL_MAP_GENTIM2D ahead of BULKF_FIELDS_LOAD, EXF_GETFORCING
1147        so xx_gentim2d can be applied to e.g. exf fields in a timely manner.
1148    o OpenAD verification experiments:
1149      - Include explicitly AUTODIFF_OPTIONS.h, COST_OPTIONS.h, and CTRL_OPTIONS.h
1150        in src files (to enable to skip the ECCO_CPPOPTIONS.h);
1151        for now, only in pkgs used in OpenAD verification experiments.
1152      - Change all except one (halfpipe_streamice) OpenAD experiments to use pkg
1153        specific option file (AUTODIFF_OPTIONS.h, COST_OPTIONS.h & CTRL_OPTIONS.h)
1154        instead of using ECCO_CPPOPTIONS.h (with all relevant options in it).
1155        This applies to both TAF (*/code_ad/) and OpenAD (*/code_oad/) tests.
1156    o OpenAD verification tests:
1157      - finish removing ALLOW_AUTODIFF_OPENAD (replaced by ALLOW_OPENAD);
1158      - finish replacing ALLOW_AUTODIFF_TAMC by ALLOW_AUTODIFF (except for
1159        tape/storage which are specific to TAF/TAMC) in pkgs used in OpenAD exp.
1160      - leave ALLOW_AUTODIFF_TAMC undef in OpenAD verification tests (*/code_oad/)
1161        and remove local copy of "tamc.h" (needed only if ALLOW_AUTODIFF_TAMC).
1162    o model/src & generic_advdiff:
1163      - change hard-coded loop-range in S/R APPLY_FORCING_T/S to set T & S
1164        forcing over 0:sNx+1, 0:sNy=1 (instead of just 1:sNx,1:sNy): Model
1165        dynamics requires valid tracer forcing only over tile interior but, for
1166        some diagnostics, may need to extend it over 1 point in tile halo region.
1167      - in gad_calc_rhs.F, update calls to gmredi_x/ytransport to get valid
1168        tendency over i,j_Min,Max range. This allows to simplfy i,j_Min,Max
1169        setting in temp/salt/ptracer_integrate.F
1170    o pkg/dic:
1171      - multiply tracer tendencies by maskInC (if ussing OBCS) before updating
1172        gchem tracers: this allows to skip the 2nd call to OBCS_APPLY_PTRACER
1173        in gchem_forcing_sep.F
1174    o pkg/autodiff & obcs:
1175      - add storage of current OB values for U & V (was already done for T & S).
1176    
1177    checkpoint65c (2014/08/30)
1178    o pkg/dic:
1179      - take out of dic_atmos.F the initialisation part (corresponding to istate=0)
1180        and move it to new S/R DIC_INI_ATMOS ; also simplify the dependencies for
1181        AD compilers (but still a Pb with multi-threading and Ajoint dependencies).
1182    o verification:
1183      - new experiment testing OBCS and DIC pkgs, using params & output from
1184        tutorial_global_oce_biogeo but limited to a sub-domain around Drake
1185        passage: take OBCS from the last year of a 2 yrs simulation and initial
1186        conditions from t=1.yr while keeping the same forcing.
1187    o model/src:
1188      - when allowFreezing=T, only reset below freezing initial Temp to Tfreezing
1189        (at any k) if checkIniTemp is not set to FALSE (default checkIniTemp=T).
1190    o pkg/diagnostics (Stats-Diags):
1191      - re-write S/R DIAGSTATS_CALC (more similar to TARGET_NEC_SX part) to:
1192        a) refine region where stats are computed, excluding where arrhFac=0 ;
1193        b) fix missing interior mask (use with OBCS) in 3-D fields statistics;
1194        c) extend regional stats over the region edges (for U or V pt location).
1195    o pkg/gchem:
1196      - add a (2nd) call to OBCS_APPLY_PTRACER in gchem_forcing_sep.F (needed since
1197        pkg/dic is currently changing/updating ptracers values beyond the OB).
1198    o verification (hs94):
1199      - convert Held & Suarez external_forcing.F (from hs94.cs, with Sigma-coords
1200        bits) to apply_forcing.F and undef USE_OLD_EXTERNAL_FORCING in experiments
1201        hs94.cs-32x32x5 and tutorial_held_suarez_cs ; also use the same version of
1202        apply_forcing.F in 2D hs94 (fwd, ad & oad) but keep LatLon hs94 unchanged.
1203    o pkg/ptracers:
1204      - implement Adams-Bashforth on pTracers (instead of on tracer tendency),
1205        switched on by setting PTRACERS_doAB_onGpTr=F (default set to doAB_onGtGs)
1206      - change exp4 secondary test (input.nlfs) to test AB on T & S & pTracer
1207        with AB-2 code (so that it get tested).
1208    o model/src:
1209      - allow to apply Adams-Bashforth on Temp & Salt (instead of on gT,gS)
1210        with AB-2 code (previously only available with AB-3 code).
1211        Also move the code (call to ADAMS_BASHFORTH S/R) form thermodynamics.F
1212        to temp/salt_integrate.F (since the 2nd part of gt/sNm1 update is done
1213        there, by calling CYCLE_AB_TRACER).
1214    o pkg/generic_advdiff:
1215      - change Tracer argument (drop bi,bj indices) in S/R GAD_CALC_RHS,
1216        GAD_C2_ADV_R, GAD_U3_ADV_R, GAD_C4_ADV_R, GAD_DIFF_R, GAD_BIHARM_R
1217        + also in GMREDI_X/Y/RTRANSPORT ; and update corresponding calls in
1218        S/R temp/salt/ptracers_integrate.F
1219    o model/src & pkg/ptracers:
1220      - remove common block variables gT,gS (in DYNVARS.h), except when
1221         USE_OLD_EXTERNAL_FORCING is defined; update TAF storage accordingly.
1222      - remove common block variable gPtr.
1223    o model/src & pkgs:
1224      - change gTracer (and/or tracer) argument (drop bi,bj indices) in S/R
1225         ADAMS_BASHFORTH(2&3), CYCLE_(AB_)TRACER, FREESURF_RESCALE_G,
1226         IMPLDIFF, SOLVE_TRIDIAGONAL & _PENTADIAGONAL, GAD_SOM_ADVECT,
1227         GAD_ADVECTION, GAD_CALC_RHS, GAD_IMPLICIT_R, TIMEAVE_CUMUL_DIF_1T
1228      + change accordingly all calling S/R.
1229      - use local temperature/salinity/ptracer tendency array (without bi,bj)
1230        in S/R temp/salt/ptracers_integrate.F
1231    o pkg/seaice:
1232      - move computation of stress contributions to rhsU/V in s/r seaice_lsr
1233        to separate s/r seaice_lsr_rhsu/v in order to be able to re-use code
1234      - make u/vIceC local variables if SEAICE_CGRID is defined only to be used
1235        in seaice_lsr
1236      - seaice_lsr.F: make local 4D arrays UXX, VYY, etc 2D
1237        in s/r seaice_lsr_calc_coeffs
1238    o pkg/mdsio:
1239      - in MDS_READ/WRITE_FIELD, stop if file-name (+prefix) is too long
1240        (e.g., > MAX_LEN_MBUF -90 ) or, in INI_MODEL_IO, if mdsioLocalDir is
1241        too long (e.g., > MAX_LEN_FNAM/2 )
1242    
1243    checkpoint65b (2014/08/12)
1244    o pkg/matrix:
1245      - pass, as argument, updated tracer field to S/R MATRIX_STORE_TENDENCY_EXP
1246    o model/src:
1247      - fix initialisation of geothermalFile; compile geothermal-flux code in
1248        natl_box verification experiment.
1249    o model/src & pkg/down_slope:
1250      - push the k loop inside S/R TIMESTEP_TRACER (now called outside the k loop).
1251      - in dwnslp_apply.F, update tracer tendency instead of the future tracer
1252        field and call S/R DWNSLP_APPLY before TIMESTEP_TRACER; this affects
1253        results at machine truncation level: update output of experiments
1254        global_ocean.90x40x15.dwnslp (FWD) and lab_sea.noseaicedyn (AD).
1255    o pkg/diagnostics (Stats-Diags):
1256      - do not cumulate the full volume when DIAGNOSTICS_FILL is
1257        called with bibjFlg < 0 (no increment of the counter for 2D/3D diag);
1258        This fix the mean statistics when DIAGNOSTICS_FILL is called multiple
1259        times (but Min,Max and StD are still wrong).
1260    o model/src:
1261      - add geothermal flux forcing: read in ini_forcing.F as time-constant
1262        field "geothermalFlux" applied in S/R APPLY_FORCING_T (apply_forcing.F)
1263    o model/src:
1264      - move CYCLE_TRACER calls from tracers_correction_step.F to temp/salt/ptracer
1265        _integrate.F so that, when leaving S/R THERMODYANMICS, theta,salt and pTrac
1266        arrays are already updated while adjustments (filters, conv.adjustment) are
1267        still applied later, in S/R TRACERS_CORRECTION_STEP.
