4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/ptracers: add Bruno Deremble's code to complete the linear surface
8      correction for tracer conservation
9      - enabled for individual ptracers by PTRACERS_linFSConserve(iTr)=.TRUE.
10    
11    checkpoint65y (2016/07/29)
12    o pkg/debug (stats):
13      - change GLOBAL_SUM to GLOBAL_SUM_TILE (result independent of tile to
14        proc/thread mapping);
15      - fix Min & Max for case where 1 thread has only empty tiles;
16      - use RL variable to count number of wet grid points (with big domain,
17        can be too large to fit into integer*4).
18    o pkg/monitor:
19      - use RL variable to count number of wet grid points (but used only for del2)
20      - add new routine to compute Advective CFL within tracer time-stepping with
21        writing delayed until next monitor output.
22    o pkg/obcs:
23      - fix bug in OBCS_BALANCE_FLOW (OBCS_balanceFacN misspelled OBCS_balanceFacW)
24    o pkg/dic & seaice:
25      - fix compilation of ocean component for coupled atm+ocn model with
26        seaice dynamics & dic.
27    
28    checkpoint65x (2016/06/11)
29    o add a license text file in main MITgcm tree.
30    o added pkg/bling:
31      - intermediate complexity biogeochemical model
32      - see bling_description.txt for details
33      - verification experiment is global_oce_biogeo_bling (for now, in
34        Contrib/verification_other/); tested daily on baudelaire with gfortran.
35      - add entry point in pkg/gchem for new pkg "bling".
36    o pkg/seaice: fix tensile stength computation
37      - replace global field tensileStrength by tensileStrFac
38      - tensileStrFac can be computed once in S/R seaice_init_varia
39      - fortunately that does not affect any verification results
40    
41    checkpoint65w (2016/05/12)
42    o pkg/ctrl/ctrl.h: fix a comma in common block list, so that code compiles
43         with ECCO_CTRL_DEPRECATED defined
44    o verification/global_ocean.cs32x15:
45      - change secondary test "viscA4" to also test "selectP_inEOS_Zc=3"
46        with "selectNHfreeSurf=1".
47    o model/src (non-hydrostatic free-surface):
48      - More "natural" expression of NH free-surface term (case selectNHfreeSurf=1):
49        was: tmpSurf/(1+tmpSurf); changed to: 1/(1+Gamma) with Gamma=1/tmpSurf.
50      - Calculate surface vertical velocity after 2-D solver adjustment (accounts
51        for EmPmR if RealFreshWaterFlux); used in RHS (cg3d_b) if exactConserv
52        and used to compute dPhiNH (in post_cg3d.F) if selectNHfreeSurf=1.
53        This fixes EmPmR contribution when selectNHfreeSurf=1 & RealFreshWaterFlux.
54      - Update output (changes at machine truncation level) of verification exp:
55        exp4 (11 digits for cg2d), global_ocean.cs32x15.viscA4 (11.d),
56        short_surf_wave (13.d) and tutorial_deep_convection.smag3d (12.d).
57    o pkg/seaice: ITD code
58      - fix picking up from a single category model by initialising
59        heff/area/hsnowITD = 0. in seaice_itd_pickup.F
60      - split a long warning message in seaice_check_pickup.F into two lines,
61        because NEC SX-ACE cannot deal with the long line.
62    o model/src:
63      - fix missing dPhiNH in pressure_for_eos.F (case: selectP_inEOS_Zc=3)
64    o pkg/seaice:
65      - add missing checks for SEAICE_ALLOW_KRYLOV and SEAICE_ALLOW_BOTTOMDRAG
66    o pkg/seaice:
67      - add basal stress as parameterisation for grounding ice
68        following Lemieux et al. (2015)
69      - turn on by setting new parameter SEAICEbasalDragK2 to a value
70        larger than 0. Lemieux et al. (2015) recommend 15.
71      - The adjoint complains with extra recomputations so there is also a
72        new cpp-flag SEAICE_ALLOW_BOTTOMDRAG that is undefined by default in
73        order to postpone the problem
74      - compile the new code in lab_sea
75    o verification/halfpipe_streamice:
76      - update both TAF and OpenAD adm output (machine truncation differences)
77    
78    checkpoint65v (2016/04/08)
79    o verification/advect_xz:
80      - increase overlap size from 3 to 4 and add new secondary test for PQM
81        advection scheme (with mono & wino limiter).
82      - change main exp. to test PPM (with weno limiter) adv.scheme on Temp.
83    o model/src:
84      - new parameters "top_Pres" & "seaLev_Z" (replacing Ro_SeaLevel and recently
85        added phi0Ref) to set vertical axis origin and phiRef origin;
86        keep Ro_SeaLevel for backward compatibility (with a warning).
87       According to coordinate and fluid type:
88        OCN in Z: top_Pres(Ref) (=rhoConst*PhiRef(1)), seaLev_Z (=rF(1), @ the top)
89        ATM in Z: top_Pres(Ref) (=rhoConst*PhiRef(1)), seaLev_Z (=rF(Nr+1) @ bottom)
90        OCN in P: top_Pres (=rF(Nr+1)), seaLev_Z (= PhiRef(Nr+1)/g, @ the top)
91        ATM in P: top_Pres (=rF(Nr+1)), seaLev_Z (= PhiRef(1)/g, @ the bottom)
92      - remove Ro_SeaLevel from ATM experiment parameter files;
93      - in tutorial_global_oce_in_p, remove Ro_SeaLevel and set top_Pres to the
94        complement; update output.txt (changes at machine truncation level).
95    o pkg/seaice/seaice_evp.F
96      - simplify computation of deltaZ and zetaZ to simple averaging following
97        Bouillon et al. (2013). This removes a lot of code, but also changes
98        verification experiment lab_sea.hb87 -> updated
99    
100    checkpoint65u (2016/03/14)
101    o pkg/generic_advdiff:
102      - from Darren: add PPM and PQM advection schemes (number 40-42 and 50-52)
103        with 2 types of limiter (see: Engwirda & Kelley, submit. to JCP);
104        Note (from Darren): unlimited PPM/PQM scheme (40 & 50) are just for
105        testing and not for actual use.
106    o model/src:
107      - add parameter "phi0Ref" to specify reference [pressure/geo] potential at
108        origin r = rF(1);
109      - add options (parameter selectP_inEOS_Zc) to select which pressure to use
110        in EOS for height coordinate: enable to include NH Pressure or to use
111        more accurate pressure vertical profile; options not linked to EOS type
112        (as previously, e.g., JMD95P/JMD95Z) but set default according to EOS type;
113      - start to implement variable gravity (along vertical): for now, only with
114        z-coords (not even z*).
115      - add Ideal Gas equation of state for height coordinate.
116      - update OpenAD output (affected at machine truncation level) of exp:
117        global_ocean.90x40x15, OpenAD (std) and tutorial_global_oce_biogeo.
118    o pkg/exf:
119      - add ALLOW_EXF_OUTPUT_INTERP cpp switch to output the result
120        of exf interpolation (before any rescaling, rotation or interpolation
121        to velocity point) for each field that gets loaded from file. This option
122        identically mimics the input file organization (e.g. record numbers in year
123        by year input files) besides the change in horizontal grid.
124      - add rotateStressOnAgrid run-time switch so that wind stress fields
125        can be provided on the A-grid in zonal/meridional direction and
126        rotated on the fly. This only applies to the case when the exf
127        interpolation is off and rotateStressOnAgrid is false by default.
128    o model/src:
129      - rename internal parameter "useDynP_inEos_Zc" to "storePhiHyd4Phys" (since
130        it's also used with pkg/atm_phys) and add few more parameters (but still
131        inactive, src code yet to come)
132    
133    checkpoint65t (2016/02/10)
134    o pkg/atm_phys:
135      - from Ruth Geen: add optical depth dependence on CO2 concentration.
136    o model/src:
137      - fix vertical inter/extra-polation of density factor rhoFacF (for anelastic)
138        for the case setCenterDr=T (delRc set from "data"); add output of rhoFacC&F.
139        Update output of exp. deep_anelastic (changes at truncation level).
140    o tools:
141      - add a hack in "remove_comments_sed" (used only with TAF) for recent
142        version of OpenMPI (shipped with FC.23): comment out the new header
143        file "mpif-sizeof.h" which causes problems to TAF.
144    o pkg/seaice:
145      - change the termination criterion so that maxits (SEAICElinearIterMax)
146        has an effect
147      - unify iteration parameters for implicit solvers (JFNK and Picard)
148        SEAICEnonLinIterMax replaces SEAICEnewtonIterMax/NPSEUDOTIMESTEPS
149        SEAICElinearIterMax replaces SEAICEkrylovIterMax/SOLV_MAX_ITER
150        SEAICEpreLinIterMax replaces SOLV_MAX_ITER in preconditioner
151        SEAICEpreNL_IterMax replaces NPSEUDOTIMESTEPS in preconditioner
152        SEAICEnonLinTol     replaces JFNKgamma_nonlin
153      - remove S/R SEAICE_FGMRES_DRIVER and put content into S/R SEAICE_JFKN
154      - add new Picard-Krylov solver, compile with SEAICE_ALLOW_KRYLOV and
155        use with SEAICEuseKrylov
156    o pkg/seaice/seaice_lsr.F
157        fix small bug: replace zetaZ by zetaZloc in S/R seaice_lsr_rhsu/v; only
158        relevant if SEAICEuseStrImpCpl=T, and even then it does not seem to have
159        an effect.
160    o pkg/seaice: add two new parameters
161      - SEAICEuseLSR to simplify the logic in seaice_dynsolver (this
162        parameter is not in any namelist)
163      - SEAICEusrPicardAsPrecon to allow s/r seaice_lsr to be used as
164        a preconditioner for the non-linear Newton iteration of the JFNK
165        solver
166    o pkg/seaice/seaice_lsr.F: replace 1./SEAICE_deltaTdyn with recip_deltaT,
167      affects some experiments at truncation level:
168      - global_ocean.cs32x15.icedyn (11 digits),
169      - global_ocean.cs32x15.seaice (11 digits),
170      - seaice_itd (12 digits), seaice_itd.lipscomb07 (12 digits) -> update
171      - also update global_ocean.cs32x15 adjoint and tangent-linear results
172    o pkg/salt_plume & pkg/thsice:
173      - for coupled  set-up with pkg/thsice in ATM and pkg/salt_plume in OCN,
174        connect salt_plume flux to ATM-OCN coupling pkgs interface:
175       a) in ATM: also cumulate salt-plume flux in S/R THSICE_SALT_PLUME (for
176         export to coupler interface) even without compiling pkg/salt_plume ;
177       b) in OCN: apply coupler salt-plume flux to pkg/salt_plume field
178         (saltPlumeFlux) just before exch call, in S/R SALT_PLUME_DO_EXCH.
179    o pkg/dic:
180      - use the updated seaice fraction (from seaice pkgs) for DIC forcing
181        instead of the previous time-step value ; done in new S/R DIC_FIELDS_UPDATE
182        called from the top of dic_biotic_forcing.F (instead of in DIC_FIELDS_LOAD);
183      - move also update with values from ATM-OCN Coupler in the same new S/R
184        (previously done in ocn_apply_import.F).
185    o tools/adjoint_options:
186      - specify explicitly "-f77" or "-f90" in default ad-optfile since TAF (default)
187        has been changed on Jan 14, 2016.
188    o pkg/ggl90:
189      - add alternative discretisation of vertical shear (off by default), to
190        compute the mean (@ grid-cell center) of vertical shear compon instead of
191        vertical shear of mean flow (@ grid-cell center).
192      - add correct parenthesis in ALLOW_GGL90_SMOOTH code to get the same truncated
193        results on adjacent faces of cubed-sphere grids; this fix the restart.
194    o pkg/atm_compon_interf:
195      - skip time-ave over cpl_atmSendFrq of Sea-Level Pressure (atmSLPr) and just
196        pass last value, stored directly before export to CPL ;
197        Note: this affects results of Coupled set-up where OCN uses useImportSLP=T
198      - remove atmSLPr from pickup files (no longer needed for restart)
199    
200    checkpoint65s (2016/01/13)
201    o eesupp & genmake2:
202       - first check for Function ETIME and, if it fails, then check for subroutine
203         ETIME and consistent output; use the appropriate version in timers.F
204    o model/src:
205      - to check restart test, add option to apply EXCH to U,V earlier, just before
206        integr_continuity; turned off by default.
207    o pkg/dic:
208      - remove CPP option USE_ATMOSCO2 (not needed)
209    o tools/tst_2+2:
210      - try to ignore difference between +0 and -0 in binary file, causing test
211        to fail for no good reason.
212    o eesupp & genmake2:
213      - put back modif from Jinxuan Zhu - change etime fct call to S/R call -
214        but also check (in genmake2) that test runs and returns meaningful results.
215    o coupler pkgs:
216      Finish implementation of optionally-exchanged variable switches (started on
217       Nov 12) with addition of few more exchanged fields, including 2-way exchange
218       of pkg/thsice vars to allow to use seaice dynamics (from pkg/seaice) & seaice
219       advection in OCN component; this requires sequential coupling.
220      coupler (pkg/atm_ocn_coupler):
221      - add argument msgUnit and iter number to CPL_SEND/RECV_ATM/OCN_FIELDS
222        routines (useful for debug).
223      - only export/import optionally exchanged fields (RunOff, seaice, Salt-Plume
224         flux, DIC fields) if corresponding switch is ON.
225      - add option to export RunOff to OCN (to use for DIC river input)
226      - add 2-way thSIce vars exchange; check for consistent cpl_sequential setting.
227      components (pkg/atm_ & ocn_compon_interf):
228      - to save memory space in ATM & OCN comp: add some #ifdef ALLOW_${PKG} around
229        optionally exchanged fields; add a check & stop in cpl_readparms.F.
230        ATMCPL.h: ALLOW_LAND for RunOff, ALLOW_THSICE for seaice, ALLOW_AIM for CO2;
231        OCNCPL.h: ALLOW_SALT_PLUME, ALLOW_DIC for DIC, ALLOW_THSICE for 2-W thsice.
232      - rename:   fracIce     -> sIceFrac_cpl (<- match coupler var name)
233        + in ATM: fracIceTime -> sIceFracTime ; seaIceTime -> sIceMassTime.
234      - add 2-way thSIce vars exchange ; add Salt-Plume flux ; add RunOff in OCN.
235      - hold in common block coupler optionally-exchanged variable switch
236        and set default "useImportXXX" accordingly; + check & stop if inconsistent.
237      - add diagnostics for all imported fields from coupler (in both OCN & ATM);
238        this is intended to replace the OCN cplFldtave.* output files (not updated
239        to contain new additional exchanged fields).
240    o pkg/dic:
241      - fix an other bug (also from 2014/08/30) in dic_atmos.F, in dic_int1=3 code.
242    o pkg/thsice:
243      - when coupled to ATM (useCoupler) with thSIce_skipThermo=T, skip reading
244        and writing of thsice pickup files.
245    o pkg/atm_compon_interf:
246      - move all field individual export-call out of cpl_export_import_data.F
247        into new S/R ATM_EXPORT_FIELDS
248    o pkg/atm_compon_interf:
249      - store state variables (for now, only thSIce fields) just before beeing
250        exported (in cpl_export_import_data.F, like on ocean side) instead of from
251        atm_store_my_data.F like all exported fluxes.
252      - new version of pickup_cpl: write field names into meta file and read meta
253        file to find field postion in pickup. Also only write/read fields meeded for
254        restart (same logic as main pickup file ; also using pickupStrictlyMatch)
255    o pkg/dic:
256      - fix bug (added on 2014/08/30) in dic_atmos.F for the case dic_int1= 2 or 3.
257    o pkg/seaice: add new parameter SEAICEpressReplFac to choose between
258        pressure replacement method (=1., default) or original Hibler (1979) (=0.)
259        value can be from domain [0,1] to average between the two methods
260    o pkg/atm_phys:
261      - allow to provide 2-d map of albedo and mixed-layer depth from files (but
262        hold fixed in time).
263    
264    checkpoint65r (2015/12/21)
265    o pkg/seaice:
266        fix bug in tridiagonal solvers for SEAICE_OLx/y>0, this affects the JFNK
267        solver (offline.dyn_jfnk) and global_ocean.cs32x15.seaice -> updated
268    o pkg/seaice:
269      - fix a bug in computing areaS in (J-J -> J-1) that affects runs
270        when SEAICEscaleSurfStress=.TRUE.,
271      - apply areaW and areaS in S/R seaice_calc_lhs
272    o pkg/atm_phys:
273      - add diagnostics for 3-D, Nr+1 levels diagnostics of radiative fluxes
274        (shortwave & longwave, net & downward) and diagnostics of temp. tendency
275        for individual contribution (convection, LSC cond, radiation)
276      - add Ruth Geen etal, GRL 2016, radiation options (see paper supp.
277        information); activated with: solar_exponent=0. and wv_exponent=-1.
278    o pkg/ggl90:
279      - within IDEMIX add upper limit for horizontal group velocity to
280        avoid instability problems in the explicit horizontal diffusion term for
281        long time steps or high resolution
282    o pkg/diagnostics:
283      - simplify setting of local-array size in diagstats_output.F: uses "numLevels"
284        (from DIAGNOSTICS_SIZE.h) to allow to write out more than Nr levels.
285    o testreport:
286      - remove "-v" (verbose option) in default mpirun command.
287    o pkg/seaice/seaice_growth:
288      - catch potential division by zero in ITD code, does not change
289        verification results
290    o pkg/ecco:
291      - retire old codes to the Attic. The calls to retired functions are
292        left in a commented form in case they ever need to be re-activated.
293      - ecco_check.F: issue warning if any old CPP option is
294        defined that corresponds to retired codes -- then stop.
295    o pkg/atm_compon_interf:
296      - change seaice fraction (use for OCN dic surf.flux) stored and sent to
297        coupler: use last time-step value instead of average over cplSendFrq_iter
298        time-step, similar to what is done for seaIceMass.
299        This will affect results (pkg/dic) of coupled ATM-OCN+dic set-up.
300    o eesupp & genmake2:
301      - from Jinxuan Zhu: change etime fct call to S/R call (fix gfortran ETIME);
302        <= remove until a fix is found for some ifort version on ia32 machine.
303    o pkg/seaice/seaice_evp:
304      - refine residual computation
305    
306    checkpoint65q (2015/11/18)
307    o pkg/seaice/seaice_evp:
308      - fix residual computations so that they no longer affect the actual
309        simulation code
310      - fix seaice_readparams to be able to actually set new parameters
311        SEAICEaEVPcStar and SEAICEaEVPalphaMin, also fix logic a little
312    o model/src:
313      - fix wrong truncation (single prec) from "FLOAT" function in expressions
314        like: deltaT*FLOAT(myIter) when myIter is large:
315         a) replaced by DFLOAT (if not seen by TAF);
316         b) remove "FLOAT" and use implicit type conversion (if seen by TAF).
317    o pkg/aim_v23:
318      - write/read the expected CO2 pickups (from S/R AIM_DO_CO2): fix reading
319        when pickupSuff is set ; do write rolling pickups + at the end of the run.
320    o pkg/atm_ocn_coupler + ocn_compon_interf:
321      - in prep for using pkg/seaice Dyn in coupled set-up, implement sequential
322        coupling option-1: ATM -(cpl)-> OCN and then OCN -(cpl)-> ATM ;
323        add corresponding call in DO_OCEANIC_PHYS.
324    o coupler pkgs:
325      Start a new way to set-up optionally-exchanged variables (previously, only
326       there for exchange_DIC): switch on/off from 1 place, at run-time, in coupler
327       data.cpl (new) instead of at compile time in ATMIDS.h & OCNIDS.h ;
328       send switch to ATM & OCN compon before reading their own "data.cpl" (so that
329       compononent param default can be set accordingly).
330      Note: this new switch (cpl_exchange_[xxx]) is not a per variable switch
331       but rather applies to a group a fields (going both ways like for DIC)
332       and corresponds to an option of coupling config.
333      coupler (pkg/atm_ocn_coupler):
334      - change parameter file from "data" to "data.cpl" (in cpl_read_params.F),
335        and read namelist directly (without eessup S/R calls) instead of
336        in the very un-flexible old way, 1 param per line, in fixed order;
337      - add error-counter to track errors (e.g., missing "data.cpl") and to stop
338        cleanly in CPL_CHECK_CPLCONFIG
339      - add new coupling-exchange selectors (some not yet active) including
340        cpl_exchange_DIC (to set to 3 to replace atmCpl_exchange_DIC=T in ATMIDS.h
341                                             and ocnCpl_exchange_DIC=T in OCNIDS.h);
342      - add 2 new S/R (CPL_SEND_ATM/OCN_CPLPARMS) to send coupler-params to each
343        component ; called directly from coupler.F, after comp. registrations;
344      - rename few variable-ID names (in ATMIDS.h & OCNIDS.h):
345         atm/ocnSeaIceName --> atm/ocnSIceMassName ; atm/ocnFCO2Name ->
346          -> atm/ocnCO2FluxName ; atm/ocnWSpdName --> atm/ocnWindSpdName
347      components (pkg/atm_ & ocn_compon_interf):
348      - add ATM/OCN_CPL_OPTIONS.h in component pkgs and include the corresponding
349        CPP header file in all pkg source files.
350      - move checking of comp. configs out of cpl_exch_configs.F into new S/R
351        ATM/OCN_CHECK_CPLCONFIG;
352      - add error-counter to track errors (e.g., in "data.cpl") and to stop
353        cleanly in ATM/OCN_CHECK_CPLCONFIG;
354      - add new S/R CPL_IMPORT_CPLPARMS to import coupling-exchange selectors
355        from coupler ; called from initialise_fixed.F, after PACKAGES_BOOT and
356        before PACKAGES_READPARMS;
357      verification/cpl_aim+ocn/:
358      - update ATMIDS.h & OCNIDS.h (in shared_code) and use new parameter file
359        "data.cpl" for coupler (in input_cpl).
360    o eesupp/inc:
361      - change the MPI-global-sum default (in CPP_EEOPTIONS.h) to:
362        #define GLOBAL_SUM_ORDER_TILES (only affects MPI built of global_sum_tile.F)
363        to always cumulate tile local-sum in the same order (still uses
364        MPI_Allreduce like standard code).
365      - in verification experiment code, remove local CPP_EEOPTIONS.h_mpi files
366        that are now identical to standard version (in eesupp/inc).
367    o pkg/shelfice:
368      - add SHELFICETransCoeffTFile for initializing spatially varying
369        heat and salt transfer coefficients
370    o pkg/atm_compon_interf & ocn_compon_interf:
371      - combine into 1 (new) S/R CPL_EXPORT_IMPORT_DATA the two previous
372        S/R CPL_EXPORT_MY_DATA & CPL_IMPORT_EXTERNAL_DATA
373      - move bi,bj loops inside S/R OCN_STORE_MY_DATA
374    o pkg/atm_ocn_coupler:
375      - initialise to zero ATMVARS.h & OCNVARS.h arrays.
376    o pkg/rbcs:
377      - select RBCS-mask for Temp & Salt the same way as for pTracer ; this allows
378        to compile with maskLEN=1 when all tracers use the same RBCS-mask.
379      - add a short report (to STDOUT) about RBCS-mask settings.
380    
381    checkpoint65p (2015/10/23)
382    o pkg/seaice/seaice_evp.F: fix store directives and key computations, since
383        there is no adjoint test for EVP, we don't know what it does to the adjoint
384        solution, but at least there are no more recomputation warnings left
385    o pkg/seaice/seaice_evp.F: slight modification of averaging so that EVP stands
386        a chance of giving the same results as a fully converged VP (JFNK) solver
387    o tools/adjoint_options/adjoint_diva:
388      - fix bug (typo) in Tang-Linear FLAGS setting for MPI + DIVA
389    o pkg/streamice:
390      - spotted bug in streamice_driving_stress using dyG where should have been dxG
391    o pkg/exf:
392      - remove STOP statement that prevented to use wind or (wind-)stress
393        interpolation for constant-in-time forcing fields (wind/stress period = 0).
394    o pkg/seaice:
395      - replace SEAICE_EVP_USE_ADAPTATION by run time parameters, requires
396        5 additionals 2D fields and 6 new store directives
397      - change logic in seaice_readparms.F: EVP code can now be turned on in
398        various ways, setting SEAICE_deltaTev is no longer required,
399        alternatively set SEAICE_evpAlpha/Beta, SEAICEuseEVPstar, SEAICEuseEVPrev,
400        or SEAICEaEVPcoeff
401    o pkg/shelfice/shelfice_thermodynamics.F
402      - redefining uLoc/vLoc to u/v, instead of 2u/v
403    o pkg/seaice/seaice_evp.F: introduce "adaptive EVP" by Madlen Kimmritz
404      - this is an intermediate state of a truely converging EVP that has
405        the potential of outperforming implicit VP methods, I do not recommend
406        using it yet.
407      - for now, "adaptive EVP" is turned on by setting SEAICE_EVP_USE_ADAPTATION
408        and all parameters are hardwired
409      - for convergence it still requires very smooth regularisations, that means,
410        if SEAICE_DELTA_SMOOTHREG is defined, deltaCreg=deltaC+deltaMin, which is
411        different from the VP case with deltaCreg=sqrt(deltaC**2+deltaMin**2); also
412        specific averaging appears to be required, still subject to tuning
413      - still needs cleaning and I need to turn parameter into runtime parameters
414      - add code to compute and print residuals of iteration, compile with
415        defining ALLOW_SEAICE_EVP_RESIDUAL to enable it
416    o pkg/seaice/seaice_evp.F: fix a bug (factor of four in front of e12Csq)
417      that entered with r1.54 on Sep04, 2015, -> update results
418    
419    checkpoint65o (2015/09/14)
420    o pkg/mom_vecinv & mom_common:
421      - add deep-atmosphere geometry factor in mom_calc_visc.F + in routines
422        called from there.
423      - add anelastic and deep-atmosphere geometry factor in pkg/mom_vecinv ; this
424        allows to use Vector-Invariant form in deep atmos and anelastic formulation
425    o pkg/seaice: introduce fast ice parameterisation following Itkin et al. (2015)
426      and Koenig-Beatty+Holland (2012)
427      - two new parameters SEAICE_tensilFac and SEAICE_tensilDepth
428      - global 2D field tensileStrength, computed in seaice_calc_ice_strength
429      - requires an extra input argument for S/R seaice_calc_viscosities
430      - tensileStrength's depth dependence is different from Itkin et al. (2015)
431        (to be changed and played with, for now exponential)
432    o pkg/seaice: introduce new parameter SEAICEscaleSurfStress (default = .FALSE.)
433      - if TRUE scale ice-ocean and ice-atmosphere stress acting on sea ice
434        by AREA according to Connelly et al. (2004), JPO.
435      - For EVP and the LSR solver, the implicit part of the drag term is
436        the only non-zero term in the denominator when there is no ice (which
437        prevented running the model with zero ice-ocean drag). If
438        SEAICEscaleSurfStress = .TRUE., this results in a division by zero
439        (or zero main diagonals BU/BV) which need to be caught. A practical
440        consequence is that for open water, the momentum equation reduce
441        to trivially 0 = 0 + 0 (for EVP). For LSR, BU/BV are reset to 1, if
442        they happen to be zero, often leading to a non-zero solution over
443        open water.
444    o pkg/seaice: revise EVP code (seaice_evp.F) in preparation for a more
445        efficient EVP method.
446      - introduce area-weighted averages for e12 (analogously to
447        seaice_calc_viscosities.F); this totally changes lab_sea.hb87 (2 digits
448        remain, but also changing the order of terms in the previous average
449        changed the results as much) -> update experiment
450      - add SEAICE_DELTA_SMOOTHREG code
451      - disentangle computation of zetaC/deltaC and zetaZ/deltaZ, also for
452        TEM-code
453      - adjust loop bounds so that only required fields are computed
454      - add new averaging code for zetaZ/deltaZ (again similar to
455        seaice_calc_viscosities.F), inactive by default for now (will change
456        results again), but will replace old code eventually
457    o eesupp/src:
458      - add an other alternative for multi-proc GLOBAL_SUM (in global_sum_tile.F)
459        to always cumulate tile local-sum in the same order
460        (option #define GLOBAL_SUM_ORDER_TILES in CPP_EEOPTIONS.h).
461        Still uses MPI_Allreduce (like standard code) but on array of tiles
462        and should be faster than GLOBAL_SUM_SEND_RECV code.
463      - switch almost all verification experiments that use GLOBAL_SUM_SEND_RECV
464        (defined in CPP_EEOPTIONS.h_mpi) to GLOBAL_SUM_ORDER_TILES instead.
465      - add CPP_EEOPTIONS.h_mpi with GLOBAL_SUM_ORDER_TILES defined in 14 more exp.:
466         aim.5l_cs, cheapAML_box, deep_anelastic, dome, fizhi-cs-32x32x40,
467         fizhi-cs-aqualev20, fizhi-gridalt-hs, global_ocean_ebm, matrix_example,
468         natl_box, solid-body.cs-32x32x1, tutorial_advection_in_gyre,
469         tutorial_baroclinic_gyre and tutorial_held_suarez_cs.
470    
471    checkpoint65n (2015/07/29)
472    o pkg/thsice:
473      - add a warning when used with pkg/aim but without updating SST
474        (stepFwd_oceMxL=F & useCoupler=F & tauRelax_MxL<>-1 ).
475    o pkg/offline:
476      - change where Offline-Fields are loaded, from load_fields_driver.F to
477        directly within FORWARD_STEP, just after updating iter number and time;
478      - move setting of GM and KPP diffusivity out of OFFLINE_FIELDS_LOAD into new
479        S/R OFFLINE_GET_DIFFUS that is called towards the end of DO_OCEANIC_PHYS;
480       These changes allow:
481        a) to recover exactly on-line results using deltaToffline=deltaTClock,
482        tested (using offlineIter0= nIter0 -1 and offlineTimeOffset= -deltaT/2)
483        both with Lin & Non-Lin Free-Surf, both with staggerTimeStep & synchronous
484        time-step, both with GM & KPP files and with recomputing these fields;
485        b) no needs to switch on staggerTimeStep anymore;
486        c) simplify rescaling of offline horiz. velocity with Non-Lin Free-Surf.
487      - update output of experiment tutorial_dic_adjoffline (only 3 digits left).
488    o pkg/offline:
489      - change (rarely used) offset-iteration parameter to an offset time (in s):
490        can easily recover previous offset-iter effect by setting offset-time
491        (offlineTimeOffset) to offset-iter x deltaToffline;
492      - do not turn-off Temp & Salinity surface relaxation when using KPP (used
493        in KPP as part of surface buoyancy forcing) in offline run.
494      - fix ptracers KPP non-local term in the case where KPP is re-computed.
495    o OpenAD
496      - Adding preliminary ggl90 test to OpenAD verification.
497        Config. with ggl90 currently diverges after 64 time steps
498        so will need more work to become more stable
499      - Adding preliminary kpp test to OpenAD verification.
500        required small tweakes in kpp_routines.F
501      - Merge and update from Krishna Narayanan's contrib area:
502        * Add one variable for preliminary OpenAD DIVA
503        * Add replacement time-stepping for OpenAD DIVA
504        * genmake2 flag -diva (but only for OpenAD; preliminary)
505        * required modifs for OAD_support
506        successful preliminary test for tutorial_global_oce_biogeo/
507    o pkg/seaice:
508      - initialise deltaC in seaice_lsr, cosmetic changes in seaice_lsr
509      - add cpp-flag SEAICE_DELTA_SMOOTHREG for option of regularising
510        delta with a smooth function in s/r seaice_calc_viscosity
511        (no effect on EVP)
512      - rename local suffix "sqr" into "sq" for more consistent variable names
513    o pkg/seaice:
514        add new parameter SEAICE_deltaMin that is used ***only***
515        for regularizing Delta (and nothing else, like the parameter
516        which is also used for all sorts of things SEAICE_EPS).
517        Defaults to SEAICE_EPS for backward compatibility only.
518    o pkg/seaice: replace erroneously storing e12Csqr on the wrong tape with
519        the wrong key by inialising it before use -> fixes a recomputation
520        problem but does not fix the gradient
521    o pkg/layers:
522      - move resetting of flux arrays to outside the iLa loop
523        (this caused layers_diapycnal to not work with more than one layer coord.)
524      - fix bug in calculation of layers_recip_delta in layers_init_fixed.F
525    o pkg/layers:
526      - remove from common block 3D layers fields (used to diagnose transport
527        in tracer coords) and declare them as local arrays in layers_calc.F
528    o pkg/seaice:
529      - Rename SEAICE_VECTORIZE_LSR_ZEBRA to SEAICE_LSR_ZEBRA and define it
530        in lab_sea forward experiment (changes results -> updated)
531      - update adjoint experiment lab_sea after cleaning up seaice_lsr_tridiagu/v
532    o pkg/seaice: modify seaice_lsr.F in order to improve the gradient
533       computations; for SEAICE_VECTORIZE_LSR
534      - move the loops over which the tridiagonal solvers (seaice_lsr_tridiagu/v)
535        sweep to the outside,
536      - remove store directives and add "CADJ loop sequential" directives
537        in analogy to model/src/solve_tridiagonal.F
538      - replace many "#ifdef SEAICE_VECTORIZE_LSR_ZEBRA" by variable loop
539        boundaries to yield more readable code. This has also the charming side
540        effect that your can use SEAICE_VECTORIZE_LSR_ZEBRA without
541        SEAICE_VECTORIZE_LSR (i.e. adjoint without recomputations in
542        seaice_lsr_tridiagu/v now requires either of these flags, vectorization
543        still requires SEAICE_VECTORIZE_LSR with SEAICE_VECTORIZE_LSR_ZEBRA as
544        an additional option)
545       The tridiagonal solvers are now completely analoguous to solve_tridiagonal.F
546       but the adjoint gradients (which are affected by this change) still explode.
547    o coupler (atm & ocn _compon_interf):
548      - avoid using Exch2 IO mapping if not suitable.
549    
550    checkpoint65m (2015/06/15)
551    o pkg/layers:
552      - clean-up old parameters setting (from Sep 2012):
553        + remove old parameters setting from common block (declared locally);
554        + stop if any old parameter is mixed with new parameters;
555        + check for valid or consistent parameter setting (e.g., layers_name)
556      - check that layers_bounds for Pot.Density are in the right range;
557        this is supposed to catch un-updated setting after recently shifting
558        potential density field "prho" by -1000 (now in "sigma" scale).
559    o pkg/layers:
560      - Added missing call to layers_fill for keeping track of tottend in
561        pkg/diagnostics/diagnostics_fill_state.F
562    o pkg/layers:
563      - added CPP flux LAYERS_FINEGRID_DIAPYCNAL to disable fine-grid binning
564        of diapycnal fluxes
565    o pkg/layers:
566      - reverted changes to interpolation to previous treatment; there
567        was never actually a problem
568    o pkg/layers:
569      - fix interpolation of layers tracers in the presence of partial cells
570      - add lots of new functionality to compute water mass transformation
571        (enabled by CPP flag LAYERS_THERMODYNAMICS)
572      - add new calls from main code (diags_oceanic_surf_flux.F,
573        thermodynamics.F, impldiff.F) and gad to save the necessary fields
574        for layers_thermodynamics calculations
575    o pkg/ptracers:
576      - add capability of stepping a passive tracer forward without advection
577        by setting PTRACERS_advScheme to 0.
578    o pkg/diagnostics:
579      - add few (threads) _BARRIER around any update of "diag_pkgStatus".
580    o pkg/layers:
581      - shift potential density field "prho" by -1000 for density layer averaging so
582        that it corresponds to usual "sigma" definition (i.e., rho(p=const)-1000);
583        Note that density bin boundaries (layers_bounds in data.layers) have
584        to be set accordingly (i.e., shifted, in sigma scale).
585    o pkg/layers:
586      - fix snap-shot output of layer thickness @ V.pt and output of pot.density
587      - fix calculation of layer non-weighted velocity and layer probability
588      - add diagnostics for pot.density used for layer averaging
589    o pkg/seaice:
590      - seaice_calc_viscosity.F: change computation of deltaC**2 to ensure
591        positiveness, modify a few comments and improve variable names,
592      - the changed computation of deltaC affects most seaice-related
593        experiments at the truncation level.
594        seaice_itd.thermo is affected by far the most, with
595        only 7 digits of agreement remaining; update experiments.
596    
597    checkpoint65l (2015/05/04)
598    o pkg/shelfice:
599      - in shelfice_thermodynamics.F, if SHELFICEBoundaryLayer=.true., then set
600        factor drKp1 to zero where it is negative (ie. do not use
601        SHELFICEBoundaryLayer if hFacC>1)
602      - the same for factor drLoc in shelfice_forcing.F
603    o tools/genmake2: move FEXTRAFLAGS from FFLAGS to FOPTIM to avoid a problem
604        with modules in ptracers, when using testreport option "-small_f"
605    o pkg/seaice/seaice_growth.F (in case of SEAICE_ITD)
606      - replace tmpscal1**1.36 by faster exp(1.36*log(tmpscal1))
607    o verification/testreport
608      - add new option -small_f
609        with this option testreport first makes the target small_f (*.f files)
610        before running make (all). This is useful for explicit inlining when
611        all sources need to be full available.
612    o pkg/exf/exf_interp.F:
613        remove previous changes related to reverse (decreasing) input grids latitude
614    
615    checkpoint65k (2015/04/01)
616    o pkg/ecco:
617        fix missing cosphi initialization; use eccoiter in place of optimcycle;
618        if autodiff is not compiled then use READ_REC_XY_RL/READ_REC_XYZ_RL
619        instead of active read/write
620    o pkg/ctrl:
621        if autodiff is not compiled then use READ_REC_XY_RL/READ_REC_XYZ_RL
622        instead of active read/write.
623    o pkg/autodiff: make autodiff_readparms.F and autodiff_whtapeio_sync.F
624        return if .NOT.useAUTODIFF
625    o pkg/seaice: add CPP brackets (cost function related).
626    o model/src:
627        add useAUTODIFF run time switch.
628    o pkg/exf/exf_interp.F:
629        add code to allow input grids with latitude starting in the north (i.e. when
630        j=1 corresponds to northern edge of field); modify global_with_exf to test
631        this feature.
632    o verification/testreport:
633      - replace "grep -A3" with POSIX conformal sed command, because there are
634        implementations of grep that cannot do contextual searches
635      - replace "cat -n" by "nl" (two occurrences), because not all implementations
636        of "cat" have the option "-n"
637    o model/src:
638        add new file gsw_teos10.F that contains 3 functions, more or less a copy
639        of the gsw_toolbox.f90 of the TEOS-10 fortran interface, that are used to
640        convert from conservative to potential temperature. For now they are not
641        called anywhere.
642    o pkg/ggl90: make "useIDEMIX" useful
643      - re-organize code in s/r ggl90_calc a little to move computations that
644        are different for idemix into separate loops (changes verification
645        experiment idemix at truncation level, 12 digits remain -> updated)
646      - requires 2 new 2D fields KappaM, verticalShear
647      - make hFacI and recip_hFacI local 3D variables that are passed to
648        s/r ggl90_idemix
649      - fix and improve some comments
650    
651    checkpoint65j (2015/02/25)
652    o pkg/openad
653      - synchronize seawater.F with version in model/src: replace routine
654        body of sw_temp by calling sw_ptmp and fix/add a few comments.
655    o pkg/mnc:
656      - change default value of pickup_read/write_mnc params to FALSE
657        (since few features are missing in reading MNC pickup files).
658    o model/src:
659      - change default (background) vertical diffusivity for salt to be the
660        temperature (background) vertical diffusivity.
661      - change background vertical diffusivity in vertical mixing pkgs ggl90,
662        kl10, my82 and pp81 from temperature diffusivity to salinity diffusivity.
663        This makes ptracers default diffusivity (that uses salt diffKr) more
664        consistent with vertical mixing schemes.
665    o verification/testreport:
666      - fix typo in "-pcls" option ;
667      - put temp files in /tmp (instead of in local dir)
668      - add option "-ncad" to use genmake2 new option "-nocat4ad"
669      - allow to use "-j" option (for multi-procs make) for AD, OAD and TLM.
670    o pkg/ggl90 (idemix code):
671      - apply few fixes ; add some missing "_d 0" ; update output of exp.
672        global_ocean.90x40x15.idemix
673    o OpenAD
674      - enable active file I/O and begin removal of work-around code
675        for OpenAD for handling control variables (memory vs. active files)
676      - new CPP options file OPENAD_OPTIONS.h
677      - revert to genarr2d gradient check for hs94.1x64x5
678      - (genarr3d tested by tutorial_global_oce_biogeo, tutorial_tracer_adjsens)
679      - gentim2d works for halfpipe_streamice but not yet hs94.1x64x5
680    o tools/genmake2:
681      - add option for an alternative Makefile (from Martin) where multiple
682        source files are sent to TAF (instead of all in one file).
683    o pkg/ggl90: add IDEMIX (Olbers and Eden, 2013)
684      - code provided by Carsten Eden as an extension of ggl90
685      - so far the code is turned on within ggl90 by setting a CPP-flag at
686        compile time; a runtime flag implementation is not yet complete
687      - tested in new verification experiment global_ocean.90x40x15.idemix
688    o verification:
689      - reduce length of the AD test run by half for experiments
690        global_ocean.cs32x15 (std + thsice) and isomip
691      - enable active file I/O for OpenAD, adjust verifications accordingly
692      - halfpipe_streamice: change gradient check from genarr2d to gentim2d
693    o verification/testreport:
694      - fix two non-POSIX sed statements so that there are no error messages
695        on Mac OS X
696      - replace hostname -s with hostname | sed 's/\..*$//'
697    o model/src/seawater.F:
698      - simplify SW_TEMP to just calling SW_PTMP with P and PR exchanged
699        (following the matlab code), which would have avoided the bug caught
700        by Matt (see below) in the first place
701    o pkg/shelfice:
702      - implement alternative discretisation of quadratic drag (selectBotDragQuadr)
703        and true distance in no-slip BC (bottomVisc_pCell) similar to bottom-drag.
704      - fix sign of friction tendency (no-slip BC) and fix u,v drag for thin
705        ice-shelf case (i.e., within surface level).
706      - add config summary in shelfice_check.F
707      - remove global variable recip_SHELFICElatentHeat and replace by a local
708        variable recip_latentHeat
709      - introduce diagnostics for friction velocity uStar (in case of
710        SHELFICEuseGammaFrict)
711      - change verification experiment isomip.htd:
712        + start from pickup (as input_ad at nIter0=8640)
713        + start from SHELFICEmassFile instead of SHELFICEloadAnomaly file
714        + test SHELFICEuseGammaFrict = .TRUE.
715        + test SHELFICEadvDiffHeatFlux = .TRUE.
716    o model/src:
717      - fix bug (Thanks to Matt) in function SW_TEMP (to convert Pot.Temp to
718        in-situ Temp) and in routine SW_TEMP (in pkg/openad);
719        update output of experiments global_with_exf.yearly and isomip (all 6).
720    o pkg/shelfice:
721      - change setting of kTopC to also be zero where there is no ice-shelf.
722      - zero out surface forcing arrays (for now, for T & S + EmPmR) where
723        ice-shelf is.
724      - first attempt to get RealFreshWaterFlux effects: for now, only without
725        SHELFICEboundaryLayer ; not consistent if using synchronous time-stepping.
726    o pkg/seaice: add the option to prescribe a fixed thickness PDF
727      for thermodynamic calculations
728      - because of divisions of the type 7/7 not exactly equal to 1, this change
729        affects results of some verification experiments by up to 4 digits:
730        global_ocean.cs32x15.seaice, lab_sea, lab_sea.fd, lab_sea.salt_plume,
731        seaice_obcs, seaice_obcs.seaiceSponge, seaice_obcs.tides
732        adjoint: lab_sea, lab_sea.noseaicedyn
733        -> updated
734    
735    checkpoint65i (2015/01/23)
736    o model/src:
737      - change units of frictionHeating field from W to W/m^2
738      - fix bug in frictional heating from stratospheric drag in
739        S/R ATM_PHYS_TENDENCY_APPLY_V
740      - with synchronous time-stepping: move resetting to zero of frictionHeating
741        field from load_fields_driver.F to thermodynamics.F ;
742      - add diagnostics for frictional heating.
743    o model/src & gmredi K3D:
744      - add frictionHeating field to pickup-files (for synchronous time-stepping)
745      - move ALLOW_EDDYPSI block out of DYNVARS.h and merge it into FFIELDS.h
746      - rename uMean,vMean --> uEulerMean,vEulerMean (+ change diagnostics name
747        and name in pickup file).
748      - fix arguments of few DIAGNOSTICS_FILL calls in gmredi_k3d.F
749    o model/src:
750      - move (from ini_forcing.F) initialisation of all arrays in header file
751        FFIELDS.h into new S/R ini_ffields.F ; this fix broken restart
752        (since Nov 2012) with option selectAddFluid=1.
753    o pkg/shelfice:
754      - change units (+ document) of newly added field "shelfIceMassDynTendency"
755      - upgrade from _RS to _RL shelficeMass & shelficeLoadAnomaly arrays.
756    o pkg/obcs: re-organize obcs_calc_stevens.F to prepare for passive tracers
757    o pkg/seaice: two new runtime parameters:
758      - SEAICE_cStar replaces the hard wired "20" in the strength formulation,
759        long overdue
760      - SEAICE_tensilFac: preparation for Koenig-Beatty+Holland (2012)
761        parameterization of tensil stress for fast ice (does not do anything yet)
762    o pkg/seaice/seaice_check.F: left over from restricted addtive Schwarz method
763        for LSR: move checking overlaps out of JFNK-if-block
764    o pkg/atm_phys:
765      - move copy of grid and dynamical fields out of atm_phys_driver.F into
766        new S/R ATM_PHYS_DYN2PHYS.
767      - fix level height for Linear Free-Surf case (to be consistent with
768        fixed-in-time pressure levels).
769    o pkg/mom_common (bottomdrag):
770      - average bottomDragFld (ALLOW_BOTTOMDRAG_CONTROL) from grid-cell center
771        to correct location (U & V point) in S/R MOM_U/V_BOTTOMDRAG;
772        update output (adm & tlm) of experiment global_ocean.90x40x15.bottomdrag.
773    o pkg/shelfice (u/v_drag):
774      - add one argument (the other velocity component) to S/R SHELFICE_U/V_DRAG;
775      - use SHELFICEDragLinear & SHELFICEDragQuadratic in shelfice_v_drag.F
776        (now similar to shelfice_u_drag.F)
777      - remove condition on bottomDragTerms when calling SHELFICE_U/V_DRAG
778        from mom_vecinv.F (similar to mom_fluxform calls).
779    o pkg/mom_common (bottomdrag):
780      - add one argument (the other velocity component) to S/R MOM_U/V_BOTTOMDRAG;
781      - add options for alternative discretisation of velocity norm in quadratic
782        bottom drag: averaging of grid-cell-center KE to U.point and V.point
783        (selectBotDragQuadr=0, original code) can produce noisy patterns; this
784        improves when averaging only the other component (e.g. vVel for U bottom
785        drag) using wet-point method (selectBotDragQuadr=2) or not (=1).
786      - add options (bottomVisc_pCell) to account for partial-cell in bottom
787        friction (no-slip BC) thus getting the true distance from the bottom;
788        off by default since this also reduces model stability (explicit bottom
789        friction). Changes produce different machine truncation with linear-drag
790        + no-slip BC: update output of experiments exp4.stevens (10 digits) and
791        front_relax (bvp & mxl, 10 & 11 digits).
792    o model/src & mom pkgs:
793      - add one more level to vertical viscosity local arrays (Nr+1, previously Nr)
794        since no-slip bottom BC uses viscosity @ k+1 to update velocity @ level k
795      - for now and until vertical mixing scheme are updated to fill up level Nr+1,
796        just copy level Nr value to level Nr+1.
797    o doc:
798      - add notes form Abhisek Chakraborty on how to close Heat & Salt budgets.
799    o pkg/shelfice:
800      - shelfice_init_varia.F, shelfice_init_fixed.F, shelfice_readparms.F,
801        SHELFICE.h: move array shelficemass to init_varia, initialise
802        from array shelficemassinit, which is set in init_fixed and
803        has option to be set from file; introduce array
804        shelficeMassDynTend array, set thru file in init_fixed
805      - NEW FILE: shelfice_step_icemass.F: update shelficemass from either
806        shelfIceFreshWaterFlux and shelficeMassDynTend or H_streamice in
807        pkg/streamice
808      - shelfice_thermodynamics.F: call shelfice_step_icemass if
809        SHELFICEMassStepping = .true.
810      - shelfice_ad_diff.list: add new subroutine shelfice_step_icemass.f
811    
812    checkpoint65h (2014/12/17)
813    o verification/global_ocean.90x40x15, global_ocean_ebm:
814      - update to generic controls.
815    o pkg/ctrl:
816      - ctrl_map_ini_genarr.F: test for igen>0
817      - ctrl_init_variables.F: add call to CTRL_MAP_INI_GENTIM2D.
818      - move gentim2d part of ctrl_map_ini_genarr.F to
819        new separate routine : ctrl_map_ini_gentim2d.F
820      - ctrl_cost_driver.F,ctrl_init.F ctrl_map_ini_genarr.F:
821        add time variable weights and cyclic controls (time mean,
822        seasonal cycle, etc) capabilities to gentim2d
823    o pkg/ecco:
824      - move reading of error, conversion to weights from
825        ecco_cost_init_fixed.F to ecco_toolbox.F (ecco_readwei)
826    o global_oce_llc90, cs32:
827      - activte sbo.
828      - CTRL_SIZE.h : add maxCtrlProc.
829      - activate the new genctrl capabilities.
830      - update following reorganization of global_oce_input_fields.tar.gz  
831    o pkg/ctrl/ctrl_ad_diff.list:
832      - add missing ctrl_init_rec.f
833    o tools/OAD_support/keepOriginal:
834      - add ctrl_init_rec.F
835    o model/src/the_main_loop.F, pkg/ctrl/ctrl_map_ini_genarr.F:
836      - avoid recomputations of xx_gentim2d_dummy.
837    o momentum diagnostics:
838      - move filling of diagnostics Um_Diss & Vm_Diss from mom_fluxform.F and
839        mom_vecinv.F to timestep.F (to include Smag-3D contribution).
840    o pkg/seaice/seaice_lsr.F:
841      - fix computation of BU/BV, make sure they are non-zero, only necessary
842        for cubed sphere exchanges and SEAICE_OLx/y>0.
843        This makes calling s/r fill_cs_corner_rl obsolete (removed).
844    o verification/global_ocean.cs32x15/input.seaice
845      - add test for strong implicit coupling and restricted addtive Schwarz
846        methods for LSR
847      - update results/output.seaice.txt
848    o verification/tutorial_global_oce_biogeo:
849      - AD & OAD set-up: switch off ALLOW_OLD_VIRTUALFLUX (like in fwd set-up)
850        and set PTRACERS_EvPrRn(1,2) to zero (for DIC & ALK);
851        update output_adm,_oadm,_tlm.txt
852    o pkg/dic:
853      - change default to "#undef ALLOW_OLD_VIRTUALFLUX" in DIC_OPTIONS.h
854      - add a stop when ALLOW_OLD_VIRTUALFLUX is defined and PTRACERS_EvPrRn
855        for tracer 1 & 2 is set (to avoid double counting of dilution effect).
856    o verification/tutorial_global_oce_biogeo:
857      - AD & OAD set-up: do not set PTRACERS_EvPrRn for tracer 1 & 2 since
858        dilution is already added by pkg/dic ALLOW_OLD_VIRTUALFLUX ;
859        update output_adm,_oadm,_tlm.txt
860    o eesupp/src:
861      - add fill_cs_corner_rl.F (_RL-copy of fill_cs_corner_rs.F)
862        and call it in seaice_lsr when using nonzero SEAICE_OLx/y
863    o pkg/seaice: introduce strongly implicit coupling, intended for stabilizing
864      LSR (following Hutchings et al. 2004)
865      - introduce zetaZ as a global variable (requires adjustments in
866        seaice_evp.F and seaice_jfnk.F) and compute analoguously to etaZ
867        in seaice_calc_viscosities.F
868      - new flag SEAICEuseStrImpCpl (default off)
869      - add new terms zetaZ*du/dy and zetaZ*dv/dx on both sides of the
870        momentum equations
871      - JFNK-solver (preconditioner) adjusted to allow using this method
872        (where it does not have any positive effect)
873    o pkg/seaice
874      - add overlap for restrictive additive Schwartz method also to LSR, but
875        turn it off by default (because it only seems to work for non-cubed
876        sphere/llc topologies)
877    o pkg/autodiff
878      - add extra exchanges in addummy_in_steppging also for mnc output
879    o pkg/seaice:
880      - add extra exchanges before dumping adjoint fields in seaice_ad_dump.F
881        to avoid stripes in the adjoint output (similar to addummy_in_stepping.F)
882    o pkg/obcs:
883      - add option to specify domain-connected piece Id along OB though files
884        (for now, only used to diagnose PhiVel; default =1 -> global correction)
885      - modify obcs_diag_balance.F to process each connected-part separately;
886        exclude OB where Id = 0 but keep the full divergence there (-> constant
887        Psi along this portion of OB and all inflow derived from grad(Phi))
888      - add example of OB-conect files in verification/so_box_biogeo/input.
889    o pkg/diagnostics:
890      - improve treatment of Open-Boundaries in Velocity-Potential calculation:
891      a) use non zero matrix element across OB and solve for Phi 1 grid point
892         outside OB (i.e, where tracer OBCS are applied).
893      b) global imbalance of inFlow/outFlow across OB: instead of modifying
894         velocity across OB, spread it uniformly along the OB in the RHS.
895    
896    checkpoint65g (2014/11/19)
897    o pkg/diagnostcis:
898      - add preconditioner off-diagonal factor (diagCG_pcOffDFac) as run-time param
899    o pkg/my82,pp81,kl10:
900      - fix ALLOW_3D_DIFFKR implementation (previously had no effect): use 3-D
901        field diffKr as background diffusivity to set minimum diffusivity value.
902    o pkg/seaice:
903      - add new parameter SEAICEuseEVPrev (for revisited EVP by
904        Bouillon et al 2013)
905      - add SEAICE_evpAlpha/Beta to namelist
906      - modify seaice_evp code to able to use SEAICEuseEVPrev. These changes
907        involve trivial re-ordering of divisions/multiplications that should not
908        have any effects, but ... they do change the results of lab_sea.hb87 so
909        that only 2 digits of agreement remain, in line with the general
910        instability/fragility of the evp-code. For now, I do not care and just
911        update the verification experiment
912    o pkg/ctrl : add generic pre-processing (xx_genarr2d_preproc etc)
913      - remove xx_genarr2d_numsmooth etc
914      - use xx_genarr2d_preproc etc instead
915      - carry out smooth_correl2D at initialization stage rather than during
916        time stepping.
917      - get smoothOpNb from xx_gentim2d_preproc
918    o global_oce_cs32 :
919      - add test of generic ecco capabilities.
920    o pkg/exf/exf_getsurfacefluxes.F :
921      - add to tmpUE/tmpVN rather than re-initializing them (conventional behavior).
922    o pkg/ctrl,ecco :
923      - omit un-necessary arguments to ctrl_cost_gen.F unless ECCO_CTRL_DEPRECATED
924        is defined.
925    o pkg/seaice: add diagnostics for Delta (deformation parameter)
926    o model/src:
927      - when ALLOW_3D_DIFFKR is defined, add a Warning if any of the vertical
928        diffusivity (background) is specified but ignored.
929    o verification:
930      - in testreport, convert hostname to lower case for default output dir name
931    o model, pkg : add useCTRL, useECCO parameters (on/off run time switch).
932    o pkg/dic: add modifications from Hajoon:
933      - add iron sedimentation flux function of the flux of PO4 out of bottom layer
934      - light attenuation: add self-shading effect by climatological Chlorophyll
935        (read from file).
936    o pkg/seaice/seaice_preconditioner.F : fix cpp flags, so that code also
937        compiles when SEAICE_ALLOW_DYNAMICS is undefined
938    o global_oce_llc90,cs32 : ecco_v4 verification exps now use separate
939        AUTODIFF_OPTIONS.h, CTRL_OPTIONS.h, ECCO_OPTIONS.h rather than
940        ECCO_CPPOPTIONS.h (i.e. replacing the deprecated, circumvoluted,
941        approach where CPP_OPTIONS.h includes an omnipotent
942        ECCO_CPPOPTIONS.h that superseeds pkgs '_OPTIONS.h').
943    o pkg/ctrl/ctrl_map_ini_genarr.F : include GMREDI_OPTIONS.h where
944        ALLOW_3D_KAPGM, ALLOW_3D_KAPREDI (to be added later) belong.
945    o pkg/seaice/SEAICE_SIZE.h : replace ALLOW_AUTODIFF_TAMC with ALLOW_AUTODIFF
946        to avoid needing AUTODIFF_OPTIONS.h anytime SEAICE_SIZE.h is included
947        (it seems that THSICE_SIZE.h, PTRACERS_SIZE.h have the same issue...)
948    o model/src, pkg/smooth, profiles, salt_plume, seaice, exf, ecco, ctrl :
949      add ECCO_OPTIONS.h, AUTODIFF_OPTIONS.h, CTRL_OPTIONS.h when needed
950      - ECCO_OPTIONS.h is needed when including ecco_cost.h, ecco.h
951      - AUTODIFF_OPTIONS.h is needed when including tamc.h, tamc_keys.h
952      - CTRL_OPTIONS.h is needed when including ctrl.h, optim.h, etc
953    o pkg/ctrl,ecco,exf :
954      - remove variables associated with NON-generic costs,
955        unless ECCO_CTRL_DEPRECATED is defined.
956      - remove NON-generic NON-obcs controls,
957        unless ECCO_CTRL_DEPRECATED is defined.
958    o pkg/ctrl : added ctrl_local_params.h
959    o pkg/ecco : added ecco_local_params.h
960    o verification : added ECCO_CTRL_DEPRECATED to most as and oad
961        experiments, which will progressively be removed once the
962        experiments are revised to use only generic controls/costs.
963    
964    checkpoint65f (2014/10/13)
965    o pkg/ctrl, ecco, seaice : minor changes in headers
966    o global_oce_llc90,cs32 : ecco_v4 verification exps now test generic
967        cost function and control capabilities added since checkpoint65c.
968    o pkg/ctrl: regroup all obcs ctrl variables in CTRL_OBCS.h.
969    o pkg/ecco: increase modularity and improve logic
970      - ecco_toolbox.F (new) : basic operations that are often used,
971        including ecco_zero, ecco_cp, ecco_cprsrl, ecco_diffmsk,
972        ecco_addcost, ecco_add, ecco_div, ecco_readbar.
973      - cost_gencal.F (new) : determine filnames and records.
974      - cost_genread.F, cost_generic.F : condense code using ecco_toolbox.
975      - cost_generic.F : use spzeroloc rather than hard-coded -9999,
976        and exploit the above functions leading to more compact code.
977      - cost_genread.F : rm un-necessary arguments, re-arrange args order.
978      - ecco_check.F, ecco_readparms.F : bring logic up to date (using_tpj,
979        using_ers, using_gfo, using_mdt is now only defined within gencost)
980    o pkg/ecco: extend generic cost capabilities
981      - pkg/ecco : added 3D gencost (ALLOW_GENCOST3D), added gencost
982        capabilities via gencost_preproc (+ _c,_i,_r related params),
983        gencost_posproc (+ _c,_i,_r related params), gencost_nrecperiod,
984        gencost_outputlevel arguments to cost_generic
985      - pkg/ecco/cost_genread.F (new) : interface between cost_generic
986        and active_read, making room for gencost_preproc to take effect.
987        Added preproc code ('climmon') to replace GENERIC_BAR_MONTH.
988      - pkg/ecco/cost_generic.F :
989        compute and store misfit maks*(model-data) in localdif that is
990        then used in cost and for output, output misfit if outlev.GT.0
991      - pkg/ecco/cost_averagesfields.F : depend on gencost_barskip
992        rather gencost_barfile for deciding whether to write barfile
993      - pkg/ecco/ecco_cost_driver.F : extract call to cost_profiles from cost_hyd
994      - pkg/ecco/ecco_cost_init_fixed.F : extract gencost weights from
995        ecco_cost_weights, re-activate ecco_summary, determine gencost_barskip
996      - pkg/ecco/ecco_summary.F : report gencost variables
997      - pkg/ecco/cost_gencost_customize.F : treat case of scatterometer costs
998    o pkg/sea/SEAICE_OPTIONS.h : add ALLOW_COST_ICE, ALLOW_SEAICE_COST_SMR_AREA
999    o pkg/ecco: internal re-organization
1000      - resolve un-necessary dependancies within pkg/ecco and to pkg/ctrl
1001        (rm includes of optim.h and ctrl.h, replace optimcycle with eccoiter,
1002        mv relevant variables definition from ecco_cost.h to ecco.h,
1003        make sure gencost routines only include ecco.h)
1004      - throughout : add missing CCP switches, rm unused variables,
1005        and rm un-necessary CPP switches
1006      - throughout gencost routines : replace modelstartdate with
1007        gencost_startdate when needed
1008      - cost_bp_read.F : use arguments, instead of common blocs
1009        so that it can be used also by (new) cost_gencost_bpv4.F
1010      - ecco_init_varia.F : initialize RHOsumGlob_0, VOLsumGlob_0
1011      - ecco_phys.F : compute etanFull
1012      - ecco_readparms.F : rename using_topex as using_tpj, add
1013        bpv4-grace to gencost list, initialize added parameters
1014      - ecco_summary.F : include SIZE.h needed for augmented ecco.h
1015    
1016    checkpoint65e (2014/09/28)
1017    o pkg/obcs:
1018      - replaced the just-added CPP options with run-time variables
1019        (see pkg/obcs/OBCS_PARAMS.h for details)
1020    o pkg/obcs:
1021      - add additional CPP options for sponge boundary layers
1022        (see pkg/obcs/OBCS_OPTIONS.h for details)
1023    o pkg/atm_phys:
1024      - implement simple (obliquity only, assuming circular planet orbit)
1025        seasonal cycle for incoming insolation ; used when run-time parameter
1026        "select_incSW" is set to 1 ; by default (=0), uses old unchanged formula.
1027    o pkg/exf, pkg/ecco, pkg/ctrl:
1028      - add ctrlUseGen and .NOT.ctrlUseGen exclusive brackets
1029      - activate gentim2d for xx_atemp,xx_aqh,xx_swdown,xx_lwdown,xx_precip
1030      - implement gentim2d for xx_tauu, xx_tauv
1031    o pkg/ctrl, pkg/ecco :
1032      - fix and complement the generic controls implementation
1033    o pkg/exf/exf_getclim.F, exf_getffields.F, exf_getsurfacefluxes.F,
1034        pkg/shelfice/shelfice_thermodynamics.F,
1035        verification/hs94.1x64x5/code_ad/ctrl_map_gentim2d.F,
1036        verification/hs94.1x64x5/code_oad/ctrl_map_gentim2d.F :
1037      - add weight in CTRL_GET_GEN calls
1038    o pkg/ctrl :
1039      - ctrl_get_gen.F : add weight as input parameter, and apply
1040        it directly rather than using smooth_correl2Dw (to be retired).
1041      - ctrl_map_gentim2d.F : add wgentim2d in CTRL_GET_GEN call
1042    o pkg/ctrl :
1043      - introduce run time switch ctrlUseGen (in ctrl.h, ctrl_check.F,
1044        ctrl_init_variables.F, ctrl_readparms.F, ctrl_summary.F)
1045      - re-activate ctrl_summary (call in ctrl_init.F)
1046    o pkg/ctrl/ctrl_cost_gen.F :
1047      - fix CCP brackets, remove un-necessary myiter, mytime
1048    o pkg/ecco, pkg/ctrl :
1049      - remove cost_genctrl.F (now pkg/ctrl/ctrl_cost_driver.F)
1050      - remove cost_forcing_gen.F (now pkg/ctrl/ctrl_cost_gen2d.F)
1051      - add ctrl_cost_driver.F (replaces pkg/ecco/cost_genctrl.F)
1052      - add ctrl_cost_gen2d.F (replaces pkg/ecco/cost_forcing_gen.F)
1053    
1054    checkpoint65d (2014/09/15)
1055    o pkg/ctrl/CTRL_GENARR.h, ctrl_readparms.F :
1056      - add xx_genarr2d_bounds,xx_genarr3d_bounds,
1057        xx_genarr2d_numsmooth, xx_genarr3d_numsmooth
1058    o pkg/ctrl/ctrl_map_ini_genarr.F :
1059      - remove compilation failure
1060      - replace hard coded example
1061      - use ctrl_map_ini_gen2D, 3D
1062    o pkg/ctrl/ctrl_pack.F, ctrl_unpack.F :
1063      - on/off switch based upon xx_genarr2d_weight,3d
1064    o src/packages_init_variables.F :
1065      - regroup pkg/estimation calls
1066      - remove CTRL_MAP_INI, CTRL_MAP_INI_ECCO
1067        (moved to ctrl_init_variables)
1068    o cost/cost_init_varia.F :
1069      - remove ecco_cost_init_varia
1070        (moved to ecco_init_varia)
1071    o ctrl/ctrl_init_variables.F :
1072      - add CTRL_MAP_INI, CTRL_MAP_INI_ECCO
1073      - add CTRL_MAP_INI_GENARR, SEAICE_CTRL_MAP_INI
1074    o ctrl/ctrl_map_ini.F :
1075      - remove ctrl_map_ini_genarr, seaice_ctrl_map_ini
1076        (moved to ctrl_init_variables)
1077    o ctrl/ctrl_map_ini_ecco.F :
1078      - remove ECCO_PHYS (mv to ecco_init_varia)
1079      - remove seaice_ctrl_map_ini (mv to ctrl_init_variables)
1080    o ecco/ecco_ad_diff.list :
1081      - add ecco_init_varia.f
1082    o ecco/ecco_init_varia.F
1083      - new routine
1084    o pkg/streamice:
1085      - move call to STREAMICE_INITIALIZE_PETSC from the_model_main.F
1086        to streamice_init_fixed.F ; fix setting of STREAMICEisOn.
1087      - from model/src, only call pkg/streamice routines if useStreamIce is TRUE.
1088    o pkg/generic_advdiff:
1089      - fix bug causing negatives in GAD_SMOLARKIEWICZ_HACK, introduced 8/8/2014.
1090    o pkg/exf:
1091      - exf_getffields.F : add xxg_atemp, xxg_aqh, xxg_swdown, xxg_lwdown,
1092         xxg_precip capability
1093      - exf_wind.F : no need for ALLOW_WSPEED_CONTROL cpp switch
1094    o pkg/ctrl:
1095      - ctrl_pack.F, ctrl_unpack.F : omit (un)packing of undefined xx_gentim2d
1096    o model/src/load_fields_driver.F :
1097      - move call to CTRL_MAP_GENTIM2D ahead of BULKF_FIELDS_LOAD, EXF_GETFORCING
1098        so xx_gentim2d can be applied to e.g. exf fields in a timely manner.
1099    o OpenAD verification experiments:
1100      - Include explicitly AUTODIFF_OPTIONS.h, COST_OPTIONS.h, and CTRL_OPTIONS.h
1101        in src files (to enable to skip the ECCO_CPPOPTIONS.h);
1102        for now, only in pkgs used in OpenAD verification experiments.
1103      - Change all except one (halfpipe_streamice) OpenAD experiments to use pkg
1104        specific option file (AUTODIFF_OPTIONS.h, COST_OPTIONS.h & CTRL_OPTIONS.h)
1105        instead of using ECCO_CPPOPTIONS.h (with all relevant options in it).
1106        This applies to both TAF (*/code_ad/) and OpenAD (*/code_oad/) tests.
1107    o OpenAD verification tests:
1108      - finish removing ALLOW_AUTODIFF_OPENAD (replaced by ALLOW_OPENAD);
1109      - finish replacing ALLOW_AUTODIFF_TAMC by ALLOW_AUTODIFF (except for
1110        tape/storage which are specific to TAF/TAMC) in pkgs used in OpenAD exp.
1111      - leave ALLOW_AUTODIFF_TAMC undef in OpenAD verification tests (*/code_oad/)
1112        and remove local copy of "tamc.h" (needed only if ALLOW_AUTODIFF_TAMC).
1113    o model/src & generic_advdiff:
1114      - change hard-coded loop-range in S/R APPLY_FORCING_T/S to set T & S
1115        forcing over 0:sNx+1, 0:sNy=1 (instead of just 1:sNx,1:sNy): Model
1116        dynamics requires valid tracer forcing only over tile interior but, for
1117        some diagnostics, may need to extend it over 1 point in tile halo region.
1118      - in gad_calc_rhs.F, update calls to gmredi_x/ytransport to get valid
1119        tendency over i,j_Min,Max range. This allows to simplfy i,j_Min,Max
1120        setting in temp/salt/ptracer_integrate.F
1121    o pkg/dic:
1122      - multiply tracer tendencies by maskInC (if ussing OBCS) before updating
1123        gchem tracers: this allows to skip the 2nd call to OBCS_APPLY_PTRACER
1124        in gchem_forcing_sep.F
1125    o pkg/autodiff & obcs:
1126      - add storage of current OB values for U & V (was already done for T & S).
1127    
1128    checkpoint65c (2014/08/30)
1129    o pkg/dic:
1130      - take out of dic_atmos.F the initialisation part (corresponding to istate=0)
1131        and move it to new S/R DIC_INI_ATMOS ; also simplify the dependencies for
1132        AD compilers (but still a Pb with multi-threading and Ajoint dependencies).
1133    o verification:
1134      - new experiment testing OBCS and DIC pkgs, using params & output from
1135        tutorial_global_oce_biogeo but limited to a sub-domain around Drake
1136        passage: take OBCS from the last year of a 2 yrs simulation and initial
1137        conditions from t=1.yr while keeping the same forcing.
1138    o model/src:
1139      - when allowFreezing=T, only reset below freezing initial Temp to Tfreezing
1140        (at any k) if checkIniTemp is not set to FALSE (default checkIniTemp=T).
1141    o pkg/diagnostics (Stats-Diags):
1142      - re-write S/R DIAGSTATS_CALC (more similar to TARGET_NEC_SX part) to:
1143        a) refine region where stats are computed, excluding where arrhFac=0 ;
1144        b) fix missing interior mask (use with OBCS) in 3-D fields statistics;
1145        c) extend regional stats over the region edges (for U or V pt location).
1146    o pkg/gchem:
1147      - add a (2nd) call to OBCS_APPLY_PTRACER in gchem_forcing_sep.F (needed since
1148        pkg/dic is currently changing/updating ptracers values beyond the OB).
1149    o verification (hs94):
1150      - convert Held & Suarez external_forcing.F (from hs94.cs, with Sigma-coords
1151        bits) to apply_forcing.F and undef USE_OLD_EXTERNAL_FORCING in experiments
1152        hs94.cs-32x32x5 and tutorial_held_suarez_cs ; also use the same version of
1153        apply_forcing.F in 2D hs94 (fwd, ad & oad) but keep LatLon hs94 unchanged.
1154    o pkg/ptracers:
1155      - implement Adams-Bashforth on pTracers (instead of on tracer tendency),
1156        switched on by setting PTRACERS_doAB_onGpTr=F (default set to doAB_onGtGs)
1157      - change exp4 secondary test (input.nlfs) to test AB on T & S & pTracer
1158        with AB-2 code (so that it get tested).
1159    o model/src:
1160      - allow to apply Adams-Bashforth on Temp & Salt (instead of on gT,gS)
1161        with AB-2 code (previously only available with AB-3 code).
1162        Also move the code (call to ADAMS_BASHFORTH S/R) form thermodynamics.F
1163        to temp/salt_integrate.F (since the 2nd part of gt/sNm1 update is done
1164        there, by calling CYCLE_AB_TRACER).
1165    o pkg/generic_advdiff:
1166      - change Tracer argument (drop bi,bj indices) in S/R GAD_CALC_RHS,
1167        GAD_C2_ADV_R, GAD_U3_ADV_R, GAD_C4_ADV_R, GAD_DIFF_R, GAD_BIHARM_R
1168        + also in GMREDI_X/Y/RTRANSPORT ; and update corresponding calls in
1169        S/R temp/salt/ptracers_integrate.F
1170    o model/src & pkg/ptracers:
1171      - remove common block variables gT,gS (in DYNVARS.h), except when
1172         USE_OLD_EXTERNAL_FORCING is defined; update TAF storage accordingly.
1173      - remove common block variable gPtr.
1174    o model/src & pkgs:
1175      - change gTracer (and/or tracer) argument (drop bi,bj indices) in S/R
1176         ADAMS_BASHFORTH(2&3), CYCLE_(AB_)TRACER, FREESURF_RESCALE_G,
1177         IMPLDIFF, SOLVE_TRIDIAGONAL & _PENTADIAGONAL, GAD_SOM_ADVECT,
1178         GAD_ADVECTION, GAD_CALC_RHS, GAD_IMPLICIT_R, TIMEAVE_CUMUL_DIF_1T
1179      + change accordingly all calling S/R.
1180      - use local temperature/salinity/ptracer tendency array (without bi,bj)
1181        in S/R temp/salt/ptracers_integrate.F
1182    o pkg/seaice:
1183      - move computation of stress contributions to rhsU/V in s/r seaice_lsr
1184        to separate s/r seaice_lsr_rhsu/v in order to be able to re-use code
1185      - make u/vIceC local variables if SEAICE_CGRID is defined only to be used
1186        in seaice_lsr
1187      - seaice_lsr.F: make local 4D arrays UXX, VYY, etc 2D
1188        in s/r seaice_lsr_calc_coeffs
1189    o pkg/mdsio:
1190      - in MDS_READ/WRITE_FIELD, stop if file-name (+prefix) is too long
1191        (e.g., > MAX_LEN_MBUF -90 ) or, in INI_MODEL_IO, if mdsioLocalDir is
1192        too long (e.g., > MAX_LEN_FNAM/2 )
1193    
1194    checkpoint65b (2014/08/12)
1195    o pkg/matrix:
1196      - pass, as argument, updated tracer field to S/R MATRIX_STORE_TENDENCY_EXP
1197    o model/src:
1198      - fix initialisation of geothermalFile; compile geothermal-flux code in
1199        natl_box verification experiment.
1200    o model/src & pkg/down_slope:
1201      - push the k loop inside S/R TIMESTEP_TRACER (now called outside the k loop).
1202      - in dwnslp_apply.F, update tracer tendency instead of the future tracer
1203        field and call S/R DWNSLP_APPLY before TIMESTEP_TRACER; this affects
1204        results at machine truncation level: update output of experiments
1205        global_ocean.90x40x15.dwnslp (FWD) and lab_sea.noseaicedyn (AD).
1206    o pkg/diagnostics (Stats-Diags):
1207      - do not cumulate the full volume when DIAGNOSTICS_FILL is
1208        called with bibjFlg < 0 (no increment of the counter for 2D/3D diag);
1209        This fix the mean statistics when DIAGNOSTICS_FILL is called multiple
1210        times (but Min,Max and StD are still wrong).
1211    o model/src:
1212      - add geothermal flux forcing: read in ini_forcing.F as time-constant
1213        field "geothermalFlux" applied in S/R APPLY_FORCING_T (apply_forcing.F)
1214    o model/src:
1215      - move CYCLE_TRACER calls from tracers_correction_step.F to temp/salt/ptracer
1216        _integrate.F so that, when leaving S/R THERMODYANMICS, theta,salt and pTrac
1217        arrays are already updated while adjustments (filters, conv.adjustment) are
1218        still applied later, in S/R TRACERS_CORRECTION_STEP.
1219    o model/src:
1220      - store in common bloc array "rhoInSitu" the virtual potential temperature
1221        anomaly that is used to compute geopotential: this make the atmos code
1222        more similar to ocean code which already uses rhoInSitu in calc_phi_hyd.F
1223    o pkg/seaice/seaice_lsr.F
1224      - rename integer variable ilcall to ipass (that's what it is called
1225        in the residual diagnostics
1226      - change time stepping for NPSEUDOTIMESTEP > 2 (does not change the
1227        default) for improved non-linear convergence of the first few steps
1228      - adjust a few comments and add new ones to explain some of the store
1229        directives
1230    o pkg/generic_advdiff (& ptracers):
1231      - re-work the code to check for valid advection scheme and for minimum
1232        size of overlap (now stored in local common bloc in gad_advscheme.F)
1233    o pkg/seaice: another attempt to make the adjoint work for sea ice dynamics
1234      - re-initialize more variables in seaice_lsr: u/vIceC, u/vIceNm1
1235      - add an auxilliary variable "bet" and fix store directives and keys in
1236        seaice_lsr_tridiagu/v, this seems to do the trick (i.e. more or
1237        less exact gradients in my tests); but there are still
1238        recomputation warning (although gradients are sort of OK), when
1239        SEAICE_LSR_VECTORIZE is not defined, so this flag and
1240        SEAICE_LSR_VECTORIZE_ZEBRA are recommended for efficiency.
1241      - update verification experiments lab_sea.
1242      - change some comments in S/R seaice_calc_viscosities
1243    o model/src:
1244      - if staggerTimeStep=T, always apply exchange to velocity field in
1245        do_stagger_fields_exchanges.F instead of in do_fields_blocking_exchanges.F
1246        (independent of using multi-dim advection or not); no effect on FWD run
1247        but affects AD results (at machine truncation level): update output of
1248        experiment 1D_ocean_ice_column (ad: 12 digits), hs94.1x64x5 (ad,oad: 13.d)
1249        and isomip (oad: 12.d).
1250    o pkg/generic_advdiff:
1251      - stop if doAB_onGtGs is set to FALSE but ignored
1252      - refine warning related to stability of tracer time-stepping
1253        regarding internal wave dynamics.
1254      - setting of AdamsBashforth_T,S when doAB_onGtGs=F: remove condition
1255        on staggerTimeStep & implicitIntGravWave (will now get a warning
1256        if potentially unstable).
1257    o pkg/kl10:
1258      - add new pkg "kl10" for mixing due to internal wave breaking, from
1259        http://www.sciencedirect.com/science/article/pii/S1463500310000144
1260        (contribution from Jody Klymak), tested in verification experiment
1261        verification/internal_wave/input.kl10/
1262    o isomip experiment:
1263      - test pkg/shelfice with Non-Lin Free-Surf in one of the FWD set-up
1264        (input.htd) and update the output.
1265    o cd_code experiments:
1266      - use default cd_code options (#undef CD_CODE_NO_AB_MOMENTUM &
1267        #undef CD_CODE_NO_AB_CORIOLIS) in experiments: cfc_example (fwd)
1268        global_ocean.90x40x15 (ad & oad) and OpenAD (ad & oad) and
1269        update the corresponding output.
1270    o pkg/seaice:
1271      - reduce the number of include files and store directives in
1272        S/R seaice_lsr_tridiagu/v
1273      - change the order of loops in one case in S/R seaice_lsr_tridiagv
1274        (only for SEAICE_VECTORIZE_LSR_ZEBRA defined), which allows me to
1275        get rid off one store directive (a TAF bug?)
1276      - add one more instance of ifdef SEAICE_VECTORIZE_LSR_ZEBRA in
1277        S/R seaice_lsr_tridiagv to change the loop range for consistency
1278      - remove ilcall, m from parameter list of S/R seaice_lsr_tridiagu/v
1279      - fix a bug that affects the JFNK solver: replace sNx/y by i/jMax in
1280        S/R seaice_lsr_tridiagu/v (requires update of
1281        offline_exf_seaice/input.dyn_jfnk)
1282    
1283    checkpoint65a (2014/07/27)
1284    o model/src:
1285      - Non-Lin Free-Surf in p/z coords: allows hFacW,S to be larger than
1286        surrounding hFacC=1 @ edge of a step with different kSurfC on either side
1287        (topo in p-coords, ice-shelf in z-coords); update output of experiments
1288        tutorial_global_oce_in_p and isomip (both AD and OpenAD output).
1289    o model/src:
1290      - collect momentum forcing tendency into local 2-D array (passed as argument
1291        to apply_forcing S/R); this simplifies mom. Forcing diagnostics and CD_CODE
1292        parts in timestep.F (without CD_CODE_NO_AB_MOMENTUM defined = the default);
1293        affects results at machine truncation level (e.g., if using OBCS_SPONGE).
1294      - collect T & S forcing tendency into local 2-D array (passed as argument to
1295        apply_forcing S/R); add 3-D diagnostics for temp & salt forcing tendency.
1296        affects results at machine truncation level (e.g., ocean: if using
1297        SHORTWAVE_HEATING ; atmos: if using FrictionHeating or (atm_Rq<>0) moist
1298        correction due to vertical advection).
1299      - update output of experiments: fizhi-cs-32x32x40 (13 digits),
1300        global_ocean.cs32x15 (fwd: icedyn, seaice, thsice, all 3 @ 11d; adm & tml:
1301        seaice_dynmix & thsice, fwd grd @ 3 & 8), hs94.1x64x5 (ad grd @ 13),
1302        obcs_ctrl (ad & fwd grd @ 12 & 7).
1303    o pkg/ptracers & diagnostics:
1304      - use ptracers (short) name (instead of long one) to make ptracers diagnostics
1305        title (to avoid some unexpected truncation); sort out ptracers diags units.
1306      - collect ptracer forcing tendency into local 2-D array (passed as argument
1307        to apply_forcing S/R); add 3-D diagnostics for ptracers forcing tendency.
1308    
1309    checkpoint65 (2014/07/18)
1310    o pkg/fizhi:
1311      - add parenthesis around fizhi tendencies in fizhi_tendency_apply.F: this
1312        affects results at machine truncation level. Update output of experiments
1313        fizhi-cs-32x32x40 (12 digits for cg2d) & fizhi-cs-aqualev20 (13 digits).
1314    o pkg/seaice: more clean up
1315      - rename TAF common block tapes to be more consistent and remove
1316        unnecessary duplicates
1317      - add store directives to remove more recomputations, but use smaller
1318        tapes (and adjust keys) when SEAICE_LSR_ADJOINT_ITER is undefined.
1319        The idea behind this flag is to reduce the memory footprint when the
1320        adjoint of the LSR is not required. As of now, defining the flag
1321        SEAICE_LSR_ADJOINT_ITER increases 4 common block tapes for 2D field by
1322        a factor of SOLV_MAX_FIXED (=500 by default in SEAICE_SIZE.h).
1323        For experiment offline_exf_seaice, this means on a linux box with gfortran
1324        nearly a factor of 10 (but keep in mind there is mostly seaice code in
1325        this experiment):

1333        6695203 1648 1382505320 1389202171 52cd8afb (SEAICE_LSR_ADJOINT_ITER)
1334      - note: there are still recomputations in global_ocean.cs32x15 and
1335        offline_exf_seaice and the gradient agreement changes (gets a
1336        little worse) for global_ocean.cs32x15 (-> update output_adm.seaice.txt)
1337      - in general, the AD gradients still are wrong
1338    o OpenAD
1339      - clean up code_oad/ directories somewhat by moving files
1340        dontCompile, dontTransform, keepOriginal to OAD_support/
1341    o model/src:
1342      - using MOM fluxform and Non-Lin Free-Surf with momDissip_In_AB=F
1343        (not currently tested): add dissipation terms before NLFS rescaling of
1344        tendencies (previously done after).
1345    o pkg/diagnostics:
1346      - write stats-diags in ascii file with more digits (same as in monitor).
1347    o pkg/down_slope:
1348      - drop the bi,bj dimension of argument recip_hFac in S/R DWNSLP_APPLY; with
1349        NLFS (not tested), use new recip_hFac value in order to conserve tracer.
1350    o model/src:
1351      - new file "apply_forcing.F" containing all the code previously in
1352        external_forcing.F, but with new argument list: pass, as new argument,
1353        the current level tendency array to update (instead of a direct update
1354        of the common bloc array). Change the corresponding calls.
1355      - add CPP option USE_OLD_EXTERNAL_FORCING (default is undef) to use
1356        EXTERNAL_FORCING_U,V,T,S subroutines (for backward compatibility).
1357    o pkg/seaice/seaice_lsr, a little bit of clean up
1358      - rearrange some code blocks, so that now all calculations for
1359        setting up the right-hand-sides done within one single block
1360        (I find that easier to read and understand)
1361      - rearrange freedrift-code to reduce the number of ifdefs
1362      - adjust some indentations and comments
1363    
1364    checkpoint64z (2014/07/10)
1365    o model/src and several pkgs:
1366      - change argument list of all S/R called from external_forcing.F and
1367        called from ptracers_forcing.F (renamed to ptracers_apply_forcing.F)
1368        to pass, as argument, the current level tendency array to update
1369        (instead of a direct update of the common bloc array).
1370      - change also (in the same way) argument list of PTRACERS_APPLY_FORCING;
1371      - rename taueddy_external_forcing.f to taueddy_tendency_apply.F
1372    o pkg/seaice/seaice_lsr.F
1373      - always initialize local arrays in seaice_lsr_tridiagu/v
1374      - add more local tapes to seaice_lsr_tridiagu/v
1375      - move storing u/vice(:,:,bi,bj) out of seaice_lsr_tridiagu/v, but
1376        keep it in bi/bj loop; this seems to be essential
1377      - gradients are still wrong but only by 4-7 orders of magnitude
1378        instead of 15 orders of magnitude, lab_sea improves a little
1379    o pkg/seaice
1380      - (pkg/autodiff) remove storing/restoring of seaiceMaskU/V that
1381        generates unnecessary code in seaice_lsr_ad
1382      - add more store directives in seaice_lsr to avoid unnecessary code
1383        in seaice_lsr_ad
1384      - exclude some residual computations in seaice_lsr when
1385        ALLOW_AUTODIFF_TAMC is defined in order to avoid unnecessary code
1386        in seaice_lsr_ad
1387      - add more storing, a new tape (model/src/the_main_loop.F) and
1388        another key for SEAICE_LSR_VECTORIZE_ZEBRA (the local keys ilockey
1389        and klockey should be checked by a specialist)
1390      - modify ( define SEAICE_VECTORIZE_LSR and SEAICE_LSR_ADJOINT_ITER )
1391        and update lab_sea after previous changes in pkg/seaice below
1392    o pkg/autodiff:
1393      - introduce useSmoothCorrel2DinAdMode, SEAICEapproxLevInAd, and
1394        viscFacInAd : run time parameters allowing for adjoint switches
1395        note : logic for useSmoothCorrel2DinAdMode is in ctrl_readparms.F
1396    o pkg/ecco:
1397      - introduce cost_gencost_boxmean.F that computes a box mean
1398        temperature (for use in adjoint sensitivity studies).
1399    o model/src/set_defaults.F : initialize viscFacAdj to 1.
1400    o pkg/mom_common/mom_calc_visc.F:
1401      - ifdef ALLOW_AUTODIFF then include viscFacAdj factor.
1402    o pkg/seaice/seaice_summary.F:
1403      - statement for SEAICEadjMODE now in autodiff_readparms.F
1404    o pkg/seaice:
1405      - remove some store directives and add new ones in an effort to get
1406        finally rid off the recomputation warnings. This is successful
1407        when SEAICE_VECTORIZE_LSR ***and*** SEAICE_LSR_ADJOINT_ITER are
1408        defined (i.e. no extensive recomputation warnings left), but there
1409        are still too many recomputations on the solver iteration level
1410      - define SEAICE_VECTORISZE_LSR in offline_exf_seaice/code_ad/SEAICE_OPTIONS.h
1411      - move definition of MPSEUDOTIMESTEPS into TAMC-block in
1412        SEAICE_SIZE.h
1413      - add a store directive in S/R seaice_calc_viscosities
1414    o pkg/seaice (ITD code):
1415      - fix definition of Hlimit for multi-threaded case
1416      - use double precision arithmetic to compute Hlimit: this affects results;
1417        update output of experiment seaice_itd.
1418    o replace content of verification/seaice_itd
1419      - instead of a 1D column use the configuration of offline_exf_seaice
1420        to test the ice thickness distribution code with ridging
1421      - this is a first shot at this experiment
1422      - change of some defaults of ridging parameters SEAICEhStar (from
1423        100 to 25) and SEAICEmuRidging (from 5 to 3) in seaice_readparms.F
1424        and lot of new comments.
1425    
1426    checkpoint64y (2014/06/20)
1427    o pkg/seaice/seaice_reg_ridge.F:
1428      - modify the regularization of very small volumes of ice; only check
1429        total volume HEFF, and do not apply correction to individual ice
1430        classes because that leads to funny patterns in the heat and fw-fluxes
1431        into the ocean. Adjust seaice_itd/results/output.txt
1432      - replace nITD by SEAICE_multDim in loop-ranges
1433    o pkg/exf:
1434      - add code to process the case field period = -12. with UV interpolation.
1435      - move debug print (formerly active when exf_verbose=T) from EXF_getFFieldRec
1436        into S/R that calls it (i.e., exf_set_gen.F, exf_set_uv.F & obcs_exf_load.F)
1437    o verification/global_with_exf:
1438      - switch all fields period to -12. (was previously untested) in input/data.exf
1439        (but keep secondary test ".yearly" unchanged); update the reference output.
1440    o pkg/cal:
1441      - new calendar type "noLeapYear" for 365 days calendar without any leap year.
1442    o pkg/exf:
1443      - new integer parameter "exf_debugLev" (default set to main model debugLevel)
1444        to replace logical switch "exf_verbose"
1445      - report in STDOUT when loading a new record (if exf_debugLev >= 3)
1446    o pkg/sbo:
1447      - update from Katherine Quinn: evaluate mass directly from density and SSH
1448        (budget using Finite Volume method) instead of from bottom pressure.
1449      - allow testreport to collect few selected SBO output ; tested in exp.
1450        global_ocean.90x40x15 (after updating the results, to include SBO output).
1451      - fix some multi-threading issues (in output part).
1452    o model/src & most packages:
1453      - always call {PKG}_READPARMS even if corresponding use{PKG}=F;
1454      - in {PKG}_READPARMS, in case use{PKG}=F: add a call to new S/R
1455        PACKAGES_UNUSED_MSG to print a weak warning when parameter file
1456        "data.{pkg}" exist ; and leave the S/R (return) just after.
1457      - more standard LAND pkg interface (land_init_fixed.F, land_check.F).
1458        + call LAND_READPARMS from packages_readparms.F
1459    o pkg/seaice:
1460      - remove code that resets useThSice in S/R seaice_readparms and
1461        replace it by a warning in S/R seaice_check
1462      - remove parameter MULTDIM, replace with nITD and runtime
1463        parameter SEAICE_multDim (still hard-wired to nITD if
1464        SEAICE_ITD is defined)
1465    
1466    checkpoint64x (2014/05/24)
1467    o verification/lab_sea:
1468      - update adjoint and TLM output following changes to pkg/salt_plume
1469      - un-do the update after putting back local recip_Cp in few places.
1470    o pkg/salt_plume: modifications by An Nguyen:
1471      - add capability to do brine rejection (salt-plume) as function of
1472        volume+tracers (instead of only salinity tracer).
1473      - conserve volume by exchanging volume from each kLev to above to
1474        accommodate in-coming brine volume
1475      - store surface and klev exchanged fraction + volume in 4 new 3-d arrays
1476      - switch KPP surf buoyancy due to brine forcing to 3-d
1477        (3 more 3-d arrays, 2 for SPforcing[T,S], 1 for boplume)
1478      - add salt_plume_volfrac, salt_plume_apply, salt_plume_tendency_apply_t
1479      - unrelatedly, also add ad-hoc capability to vary salt_plume scheme
1480        in East/West Arctic.
1481    o pkg/sbo:
1482      - incorporate modifications from Katherine Quinn to enable the use of sbo
1483        pkg in ECCO-v4 set-up ; remove SBO-TimeAve output ; add monitor-like
1484        output for future testreport verification (unfinished).
1485    o pkg/atm_phys:
1486      - change diagnostics (AtPh_Trf & AtPh_Qrf) of DARGAN_BETTSMILLER S/R:
1487        skip the reseting of t_ref & q_ref to initial t & q ; this preserve the
1488        output of S/R CAPECALCNEW (Parcel temp & q) for diagnostics.
1489    o pkg/seaice
1490      seaice_calc_ice_strength.F: modify expression to avoid divisions
1491        (affects truncation)
1492      seaice_do_ridging.F: clean up the insectarium
1493      - fix a bug that was compensated by areaScaling (-> remove areaScaling code)
1494      - added SEAICEsnowFracRidge to redistributed snow (2nd bug)
1495      - set closing/openingRate to zero where no extra iteration is need (3rd bug)
1496      - add some debugging information and error messages (warnings)
1497    o model/src: modifications relatd to atmosphere p*:
1498      - Switch to more accurate p* coordinate slope term (calc_grad_phi_hyd.F)
1499      - With p* or Sigma-P, use constant reference Pot.Temp (thetaConst) instead
1500        of vertical profile tRef in geopotential background and anomaly.
1501      - Acount for true p* correction in theta <-> T conversion in pkg/aim_v23
1502        and pkg/atm_phys.
1503      - Update FWD output of experiments: aim.5l_cs (x2), fizhi-cs-32x32x40,
1504        fizhi-cs-aqualev20, fizhi-gridalt-hs, tutorial_held_suarez_cs, cpl_aim+ocn.
1505    o pkg/seaice: fix a bug in seaice_prepare_ridging.F, forgot a sqrt
1506    o pkg/ptracers: compute ptracer source/sink due to linear free surface.
1507        not used right now, but can be used in BGC packages to fix conservation.
1508    o pkg/dic, pkg/gchem: move tracer_meanarea to gchem, so it can be used by
1509        other packages too.
1510    o pkg/seaice/seaice_calc_ice_strength.F: replace SEAICE_rhoSnow by
1511        SEAICE_rhoIce in the Rothrock (1975)-type strength calculations (bug fix)
1512    o model/src:
1513      - since we have several heat capacity (even in model/src), define "recip_Cp"
1514        as local variable (no longer in common block) to avoid any confusion.
1515      - add thetaConst in PARAMS.h (to be used with pStar or sigma-P coords).
1516    o pkg/exf:
1517      - from Jeff Scott: add option (#define EXF_CALC_ATMRHO) to calculate local
1518        air density as function of air Temp, Humidity and atm pressure.
1519    
1520    checkpoint64w (2014/05/02)
1521    o verification:
1522      - update output_adm.txt files for experiment global_ocean.cs32x15 (seaice &
1523        seaice_dynmix) and lab_sea (primary test & noseaicedyn): moving/changing
1524        code from seaice_growth.F & seaice_advdiff.F to new ridging routines
1525        seaice_reg_ridge.F seaice_do_ridging.F affects AD gradient
1526        (down to 8-7 matching digits for global_ocean and 5-6 for lab_sea).
1527    o model/src: for atmosphere in p* coords:
1528      - store factor rStarFacC**atm_kappa (= pStarFacK) in common block
1529      - implement more accurate p* coordinate slope term (in calc_grad_phi_hyd.F),
1530        but not yet activated.
1531    o pkg/seaice: fix restart problem for ITD with new ice strength parameterisation:
1532      - move computation of opnWtrFrac = 1-AREA to before computing ice strength
1533      - this changes the results (but not for any verification experiment, because
1534        none tests this), but avoids having an extra field in the restart files
1535    o pkg/seaice: remove global variable TICE (not needed)
1536      - replace by TICES or local variable where necessary (cost_seaice_test,
1537        seaice_diagnostics_state)
1538      - move copying TICE to TICES from seaice_check_pickup to seaice_read_pickup
1539      - use specific read/write routines for reading and writing individual leves
1540        of a multilevel field
1541    o pkg/ctrl & model/inc:
1542      - move additional anomaly fields of control vars (related to options:
1543         ALLOW_KAPGM_CONTROL, ALLOW_KAPREDI_CONTROL and ALLOW_BOTTOMDRAG_CONTROL)
1544        from DYNVARS.h into new header file: CTRL_FIELDS.h
1545    o pkg/seaice: some small modifications to the ridging code
1546      - make fw2ObyRidge a global variable and add the freshwater flux to
1547        seaice_growth
1548      - pass actual thickness from seaice_prepare_ridging, so that it is
1549        computed only in one place and compute it in the same way as in
1550        seaice_growth
1551      - initialise more fields in seaice_do_ridging that where cause floating
1552        point exceptions over land
1553    o pkg/seaice: preparations for ridging code and first real ridging code
1554      - move most of "PART 1" of S/R seaice_growth into a new and separate
1555        S/R seaice_reg_ridge that will both regularize the state variable after
1556        advection call the actual ridging routine;
1557      - requires to make 5 fields global fields: d_HEFFbyNEG,d_HSNWbyNEG,
1558        d_AREAbyRLX,d_HEFFbyRLX,saltFluxAdjust;
1559      - remove ridging code from seaice_advdiff
1560      - clean up remaining part 1 of seaice_growth in an attempt to make it
1561        more readable (this is probably subjective)
1562      - call seaice_itd_redist once in the initialisation phase to have the initial
1563        conditions in the correct category
1564      - finally: add new ridging routine for ITD code
1565    
1566    checkpoint64v (2014/04/11)
1567    o pkg/ecco:
1568      - add runtime parameters mdt[start,end]date[1,2]
1569      - rename variable "tpmean" as "mdt" and "topexmeanfile" as "mdtdatfile"
1570    o pkg/seaice:
1571      - make deltaC a global variable, so that it can be used in ridging code
1572      - first step towards ridging: introduce new routines that compute
1573        ice strength based on ridging parameters
1574      - add diagnostic for HSNOWITD
1575      - add opnWtrFrac as a global variable (required for ridging scheme)
1576    o pkg/salt_plume + pkg/seaice/seaice_growth.F
1577      - add SALT_PLUME_IN_LEADS flag to activate pkg/salt_plume only when ice
1578        AREA exceeds a threshold (code contributed by I.Fenty in 2011)
1579    o verification/hs94.1x64x5:
1580      - leave ALLOW_AUTODIFF_TAMC undefined in code_oad/AUTODIFF_OPTIONS.h
1581      - do not use ECCO_CPPOPTIONS.h anymore for TAF & OpenAD Adjoint tests.
1582    o autodiff:
1583      - Start to include explicitly AUTODIFF_OPTIONS.h, COST_OPTIONS.h,
1584        and CTRL_OPTIONS.h in src files (to enable to skip the ECCO_CPPOPTIONS.h)
1585        For now, only in pkgs used in verification/hs94.1x64x5.
1586      - Replace ALLOW_AUTODIFF_TAMC by ALLOW_AUTODIFF (except for tape/storage
1587        which are specific to TAF/TAMC).
1588      - Replace ALLOW_AUTODIFF_OPENAD by ALLOW_OPENAD:
1589        since ALLOW_OPENAD is defined in PACKAGES_CONFIG.h (any time pkg/openad
1590        is compiled), this simplifies/reduces which *_OPTIONS.h file to include.
1591      - OpenAD: change Makefile to generate the appropriate AD_CONFIG.h when
1592        building mitgcmuv_ad (make adAll).
1593    o pkg/ecco:
1594      - cost_gencost_seaicev4.F:
1595         reformulate proxy cost as function of sst and local param SEAICE_freeze
1596         change cost names from siv4-[sst,vol] to siv4-[deconc,exconc]
1597      - add stop statement if old names siv4-[sst,vol] are used
1598      - add snapshots + cost reports for atmospheric longwave
1599      - remove factor 0.1 in front of wtau[u,v]
1600      - replace never used flag ALLOW_TMI_COST_CONTRIBUTION with
1601         ALLOW_TMI_SST_COST_CONTRIBUTION
1602    o pkg/atm_phys:
1603      - add some diagnostics for Short-wave and for convection S/R.
1604    o pkg/seaice/seaice_growth:
1605      - fix a bug in the lateral melt parameterization for SEAICE_ITD
1606        in seaice_growth; tempFrz needs to be computed inside the i/j-loop
1607      - rearrange loop order for better vector code in the same code block
1608      - rewrite the floeDiameter formula to have fewer divisions
1609      -  (miraculously) none of this changes the results of seaice_itd
1610    o pkg/smooth:
1611      - move param smooth2Ddiffnbt to pkg/ecco
1612    o pkg/salt_plume:
1613      - salt_plume_frac.F:
1614         clean up local param names
1615         reformulate (1-frac) to frac; original 1-frac was based on swfrac code
1616    o pkg/rw:
1617      - add RS version of S/R READ_MFLDS_LEV.
1618    o pkg/streamice:
1619      - fix the restart test by writing/reading pickup_streamice files.
1620    o pkg/seaice:
1621      - refine checks for jfnk-related parameters
1622      - comment out if statement with SEAICEuseIMEX parameter as long as there
1623        is no IMEX code to avoid confusion and surprises
1624    
1625    checkpoint64u (2014/03/07)
1626    o verification/MLAdjust:
1627      - rename secondary test suffix:
1628         1.leith  -> A4FlxF  + switch to flux-form & add side-drag
1629         0.leithD -> AhFlxF  + switch to flux-form
1630         0.smag   -> AhVrDv  (use Vorticity-Div. visc form) + add side-drag
1631         0.leith  -> AhStTn  (use Strain-Tension visc form) + add side-drag
1632    o pkg/mom_vecinv:
1633      - remove unused arguments from S/R MOM_VI_HDISSIP & MOM_HDISSIP (as it used
1634        to be before mom_calc_visc.F)
1635      - skip the call to MOM_CALC_TENSION & MOM_CALC_STRAIN if not needed.
1636      - add 2nd copy of vort3 & strain that knows about lateral BC (free/no slip):
1637        this is simpler for the adjoint and for diagnostics.
1638    o model/src + pkg/momentum:
1639      - add input files for  2-D additional Western and Southern cell-edge wall
1640         (e.g., to add "thin-wall" where it is =1).
1641      - fix sideDrag option for thin-walls with Non-Lin Free-Surf
1642        using 2nd hFacZ that is computed from initial (fix domain) hFac
1643      - known limitations of thin wall implementation: not yet coded for sigma
1644        coords; not working with CD-scheme neither.
1645    o pkg/seaice:
1646      - rename recently introduced parameters from (wrong name) AB to
1647        BDF (backward difference time discretisation)
1648      - retire runtime parameters SEAICEuseAB2, SEAICE_abEps
1649    o tools/adjoint_options:
1650      - remove setting of "OPENAD=true" (now set by command line "genmake2 -oad")
1651    
1652    checkpoint64t (2014/02/01)
1653    o pkg/ecco
1654      - add compile flag ALLOW_GENCOST_TIMEVARY_WEIGHT in ECCO_OPTIONS.h and
1655        runtime logical flag gencost_timevaryweight to read daily sea-ice sigma
1656      - replace hard-coded record number and period which only work for monthly
1657        with read-in runtime param that works for other periods (month,day,year)
1658    o pkg/thsice
1659      - corrected store directive fixes thsice adjoint gradient checks
1660    o genmake2 & testreport:
1661      - add genmake2 option "-oad" to generate a Makefile for OpenAD built and
1662        in this case, use tools/adjoint_options/adjoint_oad as default AD optfile.
1663        Update testreport accordingly. No need to set "export OPENAD=true"
1664        in adjoint_options/adjoint_oad anymore (will be removed later).
1665    o pkg/shelfice:
1666      - put T & S shelfice forcing into model surfaceForcing_T,_S (for now,
1667        only if SHELFICEboundaryLayer=F); Change model/src/external_forcing.F
1668        so that surface forcing applies to k=kSurf if using pkg/shelfice.
1669    o pkg/ctrl, pkg/grdchk, pkg/ecco:
1670      - Changes to make GENARR more modular (i.e. invisible if not used)
1671    o model/src/temp_integrate.F and salt_integrate.F
1672      - re-include store directives that were removed on Dec 27th.
1673    o model/src/external_forcing_surf.F
1674      - add storage directives for EmPmR and PmEpR to avoid recomputation of
1675        seaice_model in the adjoint that is problematic when seaice_model is
1676        turned off in the adjoint. The resolved issue dated back to July when
1677        EXTERNAL_FORCING_SURF call was moved.
1678        Update global_ocean.cs32x15/*/output_adm.seaice_dynmix.txt accordingly.
1679    o pkg/exf/exf_check.F
1680      - fix a small bug again (originally found by Wentao Liu, now found again)
1681      - streamline error output
1682    o pkg/streamice and aim_v23:
1683      - replace a few "_EXCH_XY_RL (" with "_EXCH_XY_RL(", so that
1684        Apple's /usr/bin/cpp knows what to do:
1685        Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)
1686        Target: x86_64-apple-darwin13.0.0
1687    
1688    checkpoint64s (2014/01/05)
1689    o tools/adjoint_options:
1690      - switch to fastopt.net TAF server (instead of default fastopt.de) for
1691        AD optfiles adjoint_diva & adjoint_f95 (similar to adjoint_default).
1692    o model/src:
1693      - remove some unnecessary TAF storage directives in forward_step.F and
1694        in dynamics.F (note: not always removed by TAF, e.g., double storage
1695        of kappaRU,kappaRV in former version of dynamics.F).
1696    o model/src & pkg/ptracers:
1697      - call directly GAD_IMPLICIT_R & IMPLDIFF + DWNSLP_APPLY from temp_integrate.F
1698        salt_integrate.F and ptracers_integrate.F (instead of from thermodynamics.F)
1699        and remove ptracers_dwnslp_apply.F & ptracers_implicit.F
1700      - call MATRIX_STORE_TENDENCY_EXP for each tracer (in ptracers_integrate.F)
1701      - add fZon & fMer as output argument of S/R GAD_CALC_RHS.
1702      - update TAF AD-output of experiments global_ocean.90x40x15 (13 for AD-grad).
1703    o useSingleCpuInput separates single-CPU input from single-CPU output;
1704        for now only implemented for in exf_interp_read.F
1705    o verification/advect_xy:
1706      - fix missing EXCH call in local version of ini_salt.F and update output.
1707    o momentum diagnostics:
1708      - fix which deltaT is used in Total-Tendency diagnostics.
1709      - fix typo in diagnostics for momentum tendency from AB.
1710    o pkg/seaice/seaice_lsr.F: fix an initialisation bug for the
1711        SEAICE_VECTORIZE_LSR_ZEBRA option that lead to NaNs on a NEC-SX8
1712    
1713    checkpoint64r (2013/12/08)
1714    o verification/*/results:
1715      - Update reference output of experiments that were passing with just 13 digits
1716         (make it easier to detect future changes in results)
1717    o model/src & pkg/ptracers:
1718      - move calls to GAD_ADVECTION (Multi-Dim advection) from thermodynamics.F to
1719        inside temp_integrate.F and salt_integrate.F and from ptracers_advection.F
1720        to inside ptracers_integrate.F ; remove ptracers_advection.F
1721    o coupling interface pkgs:
1722        [atm_compon_interf, ocn_compon_interf & atm_ocn_coupler]
1723      - change the config check to test the agreement of Ocean Depth
1724        with ATM land/sea mask (instead of ATM orography);
1725      - send to coupler the number of coupler time-steps to do for this run:
1726        this allows to check for consistency and don't need anymore to be
1727        specified in parameter file "data";
1728      in coupler:
1729      - check consistency of RunOff map versus Ocean Depth and ATM land/sea mask.
1730      - improve report to log-file of config setting (pass log-file unit to few S/R)
1731    o pkg/compon_communic:
1732      - add coupling send/receive for non-tiled integer vector;
1733      - add S/R to check and stop if any proc has an error (similar to
1734        eesupp/src/stop_if_error.F but single thread and across Comm_World).
1735    o pkg/exch2:
1736      - in exch2*_get_rx[1,2]: use new list "W2_tileIndex" to replace search
1737        through list of all tiles my proc owns.
1738    o model/src:
1739      - AUTODIFF only: in calc_adv_flow.F, recompute rTransKp (instead of copying
1740        from rTrans) to simplify dependencies (no need to store rTrans anymore in
1741        calling S/R); this affects AD results at machine truncation level:
1742        update AD-output (TAF) of experiments: 1D_ocean_ice_column,
1743        bottom_ctrl_5x5 & obcs_ctrl (12 digits for AD grad, same FWD grad).
1744    o tools/build_options:
1745      - simplify Warnings options (-ieee & -devel cases) in linux_amd64_gfortran
1746    o coupling interface pkgs:
1747        [compon_communic, atm_compon_interf & ocn_compon_interf]
1748      - move declaration of local array "ibuf" out of header file "CPLR_SIG.h"
1749        to each S/R that needs it; remove un-used variables.
1750      - change component tile registration (cpl_register.F in both compon_interf
1751        and mitcomponent_tile_register.F) to pass the full list of tiles
1752        information (including bi,bj) in 1 vector (instead of in a bi,bj matrix).
1753      - with pkg/exch2: adopt the same convention used for I/O to define mapping
1754        towards coupler global array (unless W2_useE2ioLayOut=F):
1755         a) can now use different tiling between atm & ocn comp.
1756         b) no needs to modify the run-Off map when changing tiling (was needed
1757            even if using the same tiling between atm & ocn).
1758         c) will allow to run with blank-tiles in 1 component (e.g., for ocean
1759            full land tiles); not yet tested.
1760      - check for valid mapping from comp. tile to coupler global array
1761      - improve report of tile registration results to log file.
1762    o pkg/exch2:
1763      - in eesupp/src/eeboot.F: move call to W2_EEBOOT before Coupler
1764        tile-registration (CPL_REGISTER);
1765      - activate (un-comment) definition and setting of "W2_tileIndex" list to
1766        store the local bi,bj indices of each tile;
1767      - also print bi,bj in local report to log file;
1768      - fix pkg/debug/debug_cs_corner_uv.F for the case nSy > 1 (left from
1769        Jun 2009 modif of pkg/exch2).
1770    o testing on baudelaire:
1771      - run 2 tests at a time: no significant slow down (since enough cpu) and
1772        get the full set of test done earlier
1773      - switch the ifort test to "-devel" ; run the OpenAD test everyday.
1774    o model/src/thermodynamics.F and routines called from it:
1775      - pkg/gmredi: gmredi_residual_flow.F (replacing gmredi_calc_uvflow.F &
1776        gmredi_calc_wflow.F) to update eulerian velocity (input) into residual
1777        velocity (outp) by adding bolus velocity.
1778      - model/src: calc_adv_flow.F (replacing calc_common_factors.F) to compute
1779        mass transport from velocity + lateral grid cell area
1780      - rename calc_gt.F to temp_integrate.F (includes call to TIMESTEP_TRACER)
1781      - rename calc_gs.F to salt_integrate.F (includes call to TIMESTEP_TRACER)
1782     in thermodynamics.F
1783      - remove k from thermodynamics.F and move it to temp_integrate.F
1784        salt_integrate.F and ptracers_integrate.F (now done inside the tracer
1785        loop).
1786      - compute locally (in thermodynamics.F) 3-D velocity field that is used to
1787        advect tracers; pass it as argument to GAD_ADVECTION, GAD_SOM_ADVECT,
1788        PTRACERS_ADVECTION, TEMP_INTEGRATE, SALT_INTEGRATE, PTRACERS_INTEGRATE,
1789        GAD_IMPLICIT_R and PTRACERS_IMPLICIT
1790      - update AD-output (TAF & OAD) of experiments: 1D_ocean_ice_column,
1791        global_ocean.90x40x15, tutorial_global_oce_biogeo and
1792        tutorial_tracer_adjsens (+ TLM output).
1793    o tools/OAD_support and (verification/*/) code_oad:
1794      - OAD_support/cb2mGetModules.csh: add PACKAGES_CONFIG.h in header file to
1795        module conversion ; remove unneeded CPP_EEOPTIONS.h.
1796      - code_oad/CPP_OPTIONS.h: remove PACKAGES_CONFIG.h and use a more standard
1797        version (closer to model/inc/CPP_OPTIONS.h).
1798    o model/src:
1799      - remove parameter "useOldFreezing" from PARAMS.h and push it to the
1800        retired list of parameters (routine FREEZE has been replace by surface
1801        freezing (10.yrs ago) and by pkg/frazil (interior freezing).
1802    o pkg/gmredi:
1803      - add option (GM_CALC_TRANSP_FROM_VEL) to compute transport directly from
1804        velocity (same scheme but affects machine truncation) for GM_AdvForm.
1805      - update output of FWD experiments: front_relax.bvp,
1806        global_ocean.90x40x15.dwnslp, global_ocean.cs32x15 and ideal_2D_oce.
1807    
1808    checkpoint64q (2013/11/17)
1809    o verification:
1810      - generate new output on baudelaire (gfortran, -ieee) for OpenAD experiments
1811        tutorial_global_oce_biogeo and global_ocean.90x40x15.
1812      - generate new output (growth & melt) for seaice_itd experiment after
1813        updating the input pickup_seaice files (previously wrong).
1814    o pkg/cost:
1815      - define a "final cost function" for each tile, and use GLOBAL_SUM_TILE_RL
1816        (instead of _GLOBAL_SUM_RL) to get the final cost from all procs & threads:
1817        o this fixes global-sum value if multi-threads (since GLOBAL_SUM_RL
1818          cannot be applied to var in common block).
1819        o allows to get results independent of tile-per-proc setting (if using
1820          slower GLOBAL_SUM_SEND_RECV option).
1821      - update accordingly: seaice_cost_final.F, shelfice_cost_final.F,
1822        thsice_cost_final.F and ecco_cost_final.F (this one affects lab_sea
1823        forward gradients: update output).
1824      - update */code_oad/externalDummies.F by adding dummy GLOBAL_SUM_TILE_RL
1825        S/R and, for most exp., also comment out GLOBAL_SUM_R8.
1826    o pkg/mom_common:
1827      - move to pkg/mom_common and model/src (previously in tutorial_deep_convection
1828        code) 2nd version of isotropic 3-D Smagorinsky code interface: strain and
1829        viscosity are locally declared in dynmics.F and pass as argument to CALC_GW;
1830        ensure that all field value that are used are set.
1831    o tutorial_deep_convection (smag3d):
1832      - add missing scaling in mom_calc_smag_3d.F;
1833      - set smag3D_coeff in input.smag3d such that results do not change.
1834    o pkg/dic:
1835      - change dic_cost.F to compute cost on each tile first and then apply
1836        GLOBAL_SUM_TILE_RL: this affects forward gradient of AD experiments
1837        tutorial_dic_adjoffline & tutorial_global_oce_biogeo; update output.
1838      - remove kLev argument and use GLOBAL_SUM_TILE_RL in tracer_meanarea.
1839    o eesupp/src & pkg/mdsio:
1840      - remove gather/scatter_vector.F (from eesupp) and mdsio_read/writevector.F
1841        (from pkg/mdsio) since they are no longer used for tape IO.
1842      - move simple C subroutine "setdir.c" from pkg/compon_communic to eesupp/src
1843        (+ keep a copy in pkg/atm_ocn_coupler).
1844    o verification/isomip:
1845      - split domain in 8 squared tiles (instead of just 2) for FWD, AD & OAD tests.
1846    o tools/build_options:
1847      - optfile linux_amd64_ifort11, fast (no ieee) case:
1848        to get a working restart for all experiments, add "-fp-model source"
1849        to FOPTIM (also remove "-opt-streaming-stores auto" <- this is the default).
1850    
1851    checkpoint64p (2013/10/20)
1852    o pkg/autodiff:
1853      - adread_adwrite.F: when type and length do not match ALLOW_AUTODIFF_WHTAPEIO
1854        criteria, return to simple (default) tape IO format.
1855    o pkg/mdsio (+ eesupp/src):
1856      - rewrite/simplify tape-IO S/R (new S/R MDS_READ/WRITE_TAPE replace
1857        previous MDSREAD/WRITEVECTOR) with 2 array argument from each type (R4/R8);
1858      - fix globalFile and singleCpuIO options using simpler global mapping.
1859      - new pairs of scatter/gather vector S/R (one for each type, generated from
1860        template) corresponding to simpler global mapping.
1861      - adread_write.F: switch to new S/R (but leave old calls commented) and write
1862        to globalFile when parameter globalFiles is set to True.
1863      - switch on useSingleCpuIO in AD experiments: global_ocean.90x40x15 & isomip.
1864    o pkg/autodiff:
1865      - adread_adwrite.F: add a hack for RS arrays (when RS=real*4);
1866        with ALLOW_AUTODIFF_WHTAPEIO defined, since corresponding (real*4) is
1867        missing, just add a STOP if array type do not match.
1868    o pkg/exf:
1869      - to allow to use seaice-fraction from pkg/exf in other pkgs than pkg/seaice:
1870         rename CPP option EXF_ALLOW_SEAICE_RELAX to EXF_SEAICE_FRACTION
1871         and rename array obsSIce to exf_iceFraction.
1872    o tutorial_deep_convection:
1873      - add 1rst version of isotropic 3-D Smagorinsky code (from Louis-Philippe),
1874        for now all in this exp. code dir.
1875      - add secondary test using Smag-3D viscosity (keep very low backgroud visc for
1876        testing) and flux-limter advection scheme for Temp. (no explicit diffusion).
1877    o eesupp/src:
1878      - added SINGLE_DISK_IO option because reading of parameter files on
1879        very large number of processors did not work with existing set-up
1880    
1881    checkpoint64o (2013/09/25)
1882    o pkg/atm_phys & atm_compon_interf:
1883      - allows for coupling of gray-atmosphere (atm_phys) with ocean.
1884    o tools/build_options:
1885      - switch from "-fPIC" to "-mcmodel=medium" in optfiles: linux_amd64_gfortran
1886        & linux_amd64_ifort11 and in linux_amd64_g77 & linux_amd64_open64 also
1887        remove CPP setting (was identical to genmake2 default).
1888    o pkg/gmredi & model/src: Some updating and work done on the residual model.
1889      - created new file model/src/calc_eddy_stress.F to calculate the eddy stress.
1890      - fixed up the calculation of the eddy stress and how it is added to the
1891        external forcing via taueddy_external_forcing.F
1892      - at the moment, it is very experimental and only works with the variable eddy
1893        diffusivity calculated in gmredi_k3d.F
1894    o pkg/seaice/seaice_check.F: add a check to catch the case of specifying
1895        lw/swfluxfile instead of lw/swdownfile in data.exf together with pkg/seaice
1896    o testreport (& tools/do_tst_2+2):
1897      - for MPI test, set default COMMAND to 'mpirun -v -np TR_NPROC ./{executable}'
1898    o tools/build_options: linux_amd64_gfortran & linux_amd64_ifort11:
1899      - remove CPP='cpp -traditional -P' (this is genmake2 default)
1900      - add switch (for big setups) to use 'medium' memory-model (but leave it
1901        commented out for now). Note: needed with FC 19 to compile big setups.
1902    o pkg/atm_compon_interf:
1903      - regroup per field origin (model & pkgs) the coupling storage routines
1904         (which accumalate in time each coupling field)
1905      - move bi,bj loops inside atm_store_my_data.F and store also wind-stress;
1906        update accordingly + simplify aim_do_physics.F
1907    
1908    checkpoint64n (2013/08/26)
1909    o pkg/bbl:
1910      - update formulation to reduce dispersion of tracer properties in bbl
1911      - replaced horizontal and vertical transport parameters with velocities
1912      - changes results for verification/global_with_exf.yearly
1913    o verification/halfpipe_streamice:
1914      - change to matrix construction; update both Fwd & AD output.
1915    o verification/tutorial_tracer_adjsens:
1916      - OpenAD test: switch to vector-invariant momentum since fluxform with
1917        rStar causes problems with OpenAD; update output.
1918    o tools:
1919      - genmake2: define a common prefix for all temp-file names ; move them
1920        to local /tmp disk (but would be easy to move them back);
1921      - xmakedepend: apply the same switch for temp-files.
1922    o pkg/offline:
1923      - changes for use with rStar (NLFS): assume that we continue to provide
1924        UVELMASS/hFacW_ini & VVELMASS/hFacS_ini (hFacWi,S_ini as written in grid
1925        output files) and apply r* scaling at each time-step (function of the time
1926        varying Eta field); use normal pickup files (needed for restart with NLFS).
1927    o adjoint with OpenAD:
1928      - move OpenAD-specific files from verification/OpenAD/code_oad_all to a new
1929        package openad.  This package has to be compiled for all runs with OpenAD
1930        instead of specifying code_oad_all as a modification directory.
1931      - link the fortran templates from tools/OAD_support to the build directory
1932        for preprocessing to avoid conflicts between different setups compiled
1933        simultaneously and simplify cleanup.
1934    o pkg/exf:
1935      - in exf_getforcing.F: comment out most of the EXCH calls (fields used by
1936        main model or other pkgs are exchanged in EXF_MAPFIELDS).
1937    o model/src:
1938      - do_stagger_fields_exchanges.F: skip EXCH calls when using pkg/offline
1939        (similar to do_fields_blocking_exchanges.F).
1940    o tools/genmake2:
1941      - remove TAF output src code just before calling staf (when not doing a fresh
1942        built, will stop if things go wrong with staf).
1943      - fix target "adobj" (left from TAF version-2 transition)
1944    o pkg/diagnostics:
1945      - add a parameter to track the status of pkg/diagnostics activation;
1946        this replace/extend the use of logical param "settingDiags" (to check
1947        when adding diag to the list) to also check any DIAGNOSTICS_[]FILL* call.
1948        New S/R to print error message and stop when pkgStatus is not right.
1949      - to try: add a warning when "data.diagnostics" exist but useDiagnostics=F.
1950    
1951    checkpoint64m (2013/08/13)
1952    o model/inc:
1953      - move FCORI_MACROS.h from PARAMS(_MACROS).h to GRID_MACROS.h (left from
1954        8 yrs ago modif when Coriolis arrays were moved from PARAMS.h to GRID.h)
1955    o pkg/kpp & aim_v23:
1956      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
1957    o pkg/seaice:
1958      - restore (last time on 2011/12/24) ability to compile pkg/seaice with
1959        undefined pkg/exf ALLOW_ATM_TEMP or ALLOW_RUNOFF CPP-options.
1960      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
1961    o eesupp/src:
1962      - fix check for overlap-size argument (myOLn.GT.MAX_OLY_EXCH)
1963        in exch1_rx[_ad].template (thanks to Francois Lefeuvre report).
1964    o switch to TAF version-2:
1965      - add flow directives to "freeze" naming convention for ad-routines that
1966        are used in I/O routines of adjoint state and associated common blocks
1967        that are used in adcommon.h (backward compatible with version-1)
1968      - update all ad-optfiles (in tools/adjoint_options + few local to some
1969        verification exp) to switch to latest TAF version (currently 2.5.5);
1970        merge "*_mpi" adoptfiles into the corresponding non-mpi (but commented
1971        out except for diva).
1972      - the major change with TAF version-2 is that both the differentiated
1973        routines and the forward routines (new) are returned as part of the TAF
1974        output source code. Update genmake2 accordingly.
1975      - new output for AD experiment tutorial_global_oce_biogeo (better AD gradient
1976        with version-2 when compared to TLM or FWD gradient); other experiments
1977        output show minor changes (machine truncation level); update the few AD &
1978        TLM output with 12 matching digits only (some prior to version-2 switch).
1979    
1980    checkpoint64l (2013/08/05)
1981    o model/src:
1982      - in dynamics.F, skip the call to CALC_VISCOSITY if momViscosity=F
1983      - main_do_loop.F: no longer includes additional (AUTODIFF) header files
1984        when using TAF but only if using OpenAD.
1985    o pkg/mom_common+fluxform+vecinv:
1986      - always set horiz. viscosity arrays to background value before calling
1987        MOM_CALC_VISC (in MOM_FLUXFORM & MOM_VECINV) and call S/R MOM_CALC_VISC
1988        only when using variable horiz. viscosity (useVariableVisc=T);
1989      - simplify mom_vecinv.F (only 1 block for momViscosity).
1990    o pkg/mom_common: variable horiz. viscosity in NH code
1991      - move horiz-viscosity 3-D arrays viscAh_W & viscA4_W (used in calc_gw.F)
1992        from model/inc/NH_VARS.h to pkg/mom_common/MOM_VISC.h
1993      - store in common block (in MOM_VISC.h) logical parameters: useHarmonicVisc,
1994        useBiharmonicVisc & useVariableVisc.
1995      - fix old bug (already in 1rst implementation of variable horizontal viscosity
1996        in calc_gw.F, version 1.27, 2006/06/20):
1997        horizontal bi-harmonic viscosity in gW was missing when wiscA4W=0
1998        even if variable bi-harmonic viscosity (e.g., viscA4Grid) was non-zero.
1999      - change background horiz viscosity in vertical momentum (gW) to always be
2000        viscAhW,viscA4W (instead of switching to viscAhD, viscA4D when using
2001        any type of variable viscosity, e.g., viscAh/4Grid)
2002      - change default value of viscAhW,viscA4W to viscAhD,viscA4D (instead of
2003        viscAh,viscA4) which default to viscAh,viscA4 :  this avoid missing
2004        horiz. viscosity in W eq when just setting viscAhD/Z,viscA4D/Z (since
2005        default viscAh,viscA4 is zero).
2006    o model/src:
2007      - extend length of drC & recip_drC from Nr to Nr+1.
2008    o Divided Adjoint (DIVA) with MPI:
2009      - genmake2: do not create local ./mpi_headers dir when no file to copy into.
2010      - remove option ALLOW_DIVIDED_ADJOINT_MPI (replaced by ALLOW_DIVIDED_ADJOINT
2011        and ALLOW_USE_MPI) from model/src code and from ECCO_CPPOPTIONS.h.
2012    
2013    checkpoint64k (2013/07/23)
2014    o tools/OAD_support:
2015      - avoid the need for file "oadtempflile" in insertTemplateDir.bash
2016        and remove it from genmake2.
2017    o tools/build_options:
2018      - remove MPI_HEADER_FILES_INC setting (no longer used) and comment out
2019        MPI_HEADER_FILES list (let genmake2 find the missing headers)
2020    o verification/halfpipe_streamice:
2021      - change to driving stress formulation; update both Fwd & AD output.
2022    o tools/genmake2 and Divided Adjoint with MPI:
2023      - remove default setting of MPIINCLUDEDIR from $MPIHOME (always been broken);
2024      - only create local ./mpi_headers dir if using MPI and MPIINCLUDEDIR is set;
2025      - add new variable (LOCAL_MPI_HEADERS, replace MPI_HEADER_FILES_INC) in
2026        Makefile, which is set by genmake2, and check which mpi-headers are needed.
2027        Note: need to update adjoint_options/adjoint_diva_mpi accordingly.
2028      - update target "CLEAN" (to also remove ./mpi_headers/ dir).
2029    o testreport:
2030      - changes for Divided Adjoint Run: when file "run_ADM_DIVA" is present,
2031        perform additional runs (number of additional runs is "add_DIVA_runs" taken
2032        from file run_ADM_DIVA ; should match "nchklev_3" in file "code_ad/tamc.h").
2033    o verification/lab_sea (AD test):
2034      - change to test Divided Adjoint Run in this set-up (both standard AD test
2035        and 2 secondary AD test: noseaice + noseaicedyn); drop the evp AD test.
2036    o pkg atm_ & ocn_compon_interf:
2037      - remove cpl_earlyExpImpCall=F option (was mainly a hack added for the old
2038        staggerTimeStep implementation) and disable (retired) corresponding
2039        parameter.
2040    o pkg/offline:
2041      - comment out unused field-array: ICEM, ConvectCount, hflx[01], icem[01];
2042      - add S/R OFFLINE_CHECK to print offline parameter summary
2043        and stop if loading a file that is not used;
2044      - enable to calculate GMRedi tensor, KPP mixing and convective index
2045        when the corresponding file(s) is/are not specified (but pkg is used).
2046      - comment out resetting of monitorFreq (to endTime) since it still useful
2047        for monitoring CFL numbers and checking offline fields.
2048    o OpenAD:
2049      - do not define OAD_DEBUG (in tools/adjoint_options/adjoint_oad) to get
2050        smaller standard output) and generate new (smaller) output (on baudelaire
2051        using gfortran with -ieee) for exp. tutorial_tracer_adjsens
2052    o model/src:
2053      - call EXTERNAL_FORCING_SURF outside bi,bj loops (in do_oceanic_phys.F),
2054        (where external_forcing_adjust was called) and change list of arguments;
2055      - merge external_forcing_adjust.F into external_forcing_surf.F
2056      - put surface relaxation of SST & SSS in new S/R (forcing_surf_relax.F)
2057        which also contains balancing surface relaxation (ALLOW_BALANCE_RELAX,
2058        previously in file "balance_relax.F", now removed); remove corresponding
2059        arrays in FFIELDS.h.
2060      - EXTERNAL_FORCING_SURF is now called when using pkg/offline; implement
2061        a hack for getting back surfaceForcingS (loaded from file) when using
2062        ALLOW_OLD_VIRTUALFLUX (pkg/dic, in DIC_OPTIONS.h) in offline set-up.
2063      - update output of AD test experiment global_ocean.cs32x15.seaice_dynmix
2064        (was getting only 11 digits for AD-grad, due to different truncation
2065         error in AD code).
2066    
2067    checkpoint64j (2013/07/04)
2068    o pkg/offline:
2069      - to enable the use of other features with pkg offline (e.g., obcs),
2070        also call S/R DO_OCEANIC_PHYS in offline run - more modifs to come.
2071      - comment out "allowFreezing" (now active) in 2 offline testing exp.
2072    o pkg/exf ALLOW_RUNOFTEMP
2073      - fix sign and make compatible with temp_EvPrRn .NE. UNSET_RL
2074      - ahdded RUNOFTEMP test to verification/global_ocean.cs32x15/input.seaice
2075      - changes verification/global_ocean.cs32x15/results/output.seaice.txt
2076    o pkg/atm_phys:
2077      - allows to add some damping on uVel,vVel (strength only function of k).
2078    o verification, ad-tests:
2079      - reduce length of the simulation for AD test: global_ocean.cs32x15.seaice,
2080        global_ocean_ebm and offline_exf_seaice.thsice.
2081    o verification/halfpipe_streamice:
2082      - found a bug in s/r pkg/streamice/streamice_advect_thickness which caused
2083        flux input boundary conditions to be ignored; a fix for this bug changed
2084        verification results for forward test.
2085      - add adjoint test.
2086    o pkg/ptracers:
2087      - allow to restart without SOM pickup (resetting SOM to zero).
2088    o pkg/gmredi:
2089      - New parameterisation for the calculation of K and (GM_PsiX,GM_PsiY) added.
2090      - It uses mixing length theory and suppression by steering level effects to
2091        calculate a diffusivity used in the Redi tensor (see Bates et al., submitted
2092        to JPO, for more details).
2093      - It also uses the diffusivity to calculate an eddy induced streamfunction
2094        based on a PV closure (rather than a buoyancy closure as in GM).
2095      - New files added to pkg/gmredi:
2096        gmredi_k3d.F calculates the diffusivity for the Redi tensor and the eddy
2097          induced overturning streamfunction (called from gmredi_calc_tensor)
2098        gmredi_calc_eigs.F calculates the eigenvalues and eigenvectors required
2099          for use in gmredi_k3d
2100        gmredi_calc_urms.F calculates the the rms eddy velocity used to calculate
2101          the eddy diffusivity
