5      ==============================      ==============================
6    
7    checkpoint64q (2013/11/17)
8    o verification:
9      - generate new output on baudelaire (gfortran, -ieee) for OpenAD experiments
10        tutorial_global_oce_biogeo and global_ocean.90x40x15.
11      - generate new output (growth & melt) for seaice_itd experiment after
12        updating the input pickup_seaice files (previously wrong).
13    o pkg/cost:
14      - define a "final cost function" for each tile, and use GLOBAL_SUM_TILE_RL
15        (instead of _GLOBAL_SUM_RL) to get the final cost from all procs & threads:
16        o this fixes global-sum value if multi-threads (since GLOBAL_SUM_TILE_RL
17          cannot be applied to var in common block).
18        o allows to get results independent of tile-per-proc setting (if using
19          slower GLOBAL_SUM_SEND_RECV option).
20      - update accordingly: seaice_cost_final.F, shelfice_cost_final.F,
21        thsice_cost_final.F and ecco_cost_final.F (this one affects lab_sea
22        forward gradients: update output).
23      - update */code_oad/externalDummies.F by adding dummy GLOBAL_SUM_TILE_RL
24        S/R and, for most exp., also comment out GLOBAL_SUM_R8.
25    o pkg/mom_common:
26      - move to pkg/mom_common and model/src (previously in tutorial_deep_convection
27        code) 2nd version of isotropic 3-D Smagorinsky code interface: strain and
28        viscosity are locally declared in dynmics.F and pass as argument to CALC_GW;
29        ensure that all field value that are used are set.
30    o tutorial_deep_convection (smag3d):
31      - add missing scaling in mom_calc_smag_3d.F;
32      - set smag3D_coeff in input.smag3d such that results do not change.
33    o pkg/dic:
34      - change dic_cost.F to compute cost on each tile first and then apply
35        GLOBAL_SUM_TILE_RL: this affects forward gradient of AD experiments
36        tutorial_dic_adjoffline & tutorial_global_oce_biogeo; update output.
37      - remove kLev argument and use GLOBAL_SUM_TILE_RL in tracer_meanarea.
38    o eesupp/src & pkg/mdsio:
39      - remove gather/scatter_vector.F (from eesupp) and mdsio_read/writevector.F
40        (from pkg/mdsio) since they are no longer used for tape IO.
41      - move simple C subroutine "setdir.c" from pkg/compon_communic to eesupp/src
42        (+ keep a copy in pkg/atm_ocn_coupler).
43    o verification/isomip:
44      - split domain in 8 squared tiles (instead of just 2) for FWD, AD & OAD tests.
45    o tools/build_options:
46      - optfile linux_amd64_ifort11, fast (no ieee) case:
47        to get a working restart for all experiments, add "-fp-model source"
48        to FOPTIM (also remove "-opt-streaming-stores auto" <- this is the default).
49    
50    checkpoint64p (2013/10/20)
51    o pkg/autodiff:
52      - adread_adwrite.F: when type and length do not match ALLOW_AUTODIFF_WHTAPEIO
53        criteria, return to simple (default) tape IO format.
54    o pkg/mdsio (+ eesupp/src):
55      - rewrite/simplify tape-IO S/R (new S/R MDS_READ/WRITE_TAPE replace
56        previous MDSREAD/WRITEVECTOR) with 2 array argument from each type (R4/R8);
57      - fix globalFile and singleCpuIO options using simpler global mapping.
58      - new pairs of scatter/gather vector S/R (one for each type, generated from
59        template) corresponding to simpler global mapping.
60      - adread_write.F: switch to new S/R (but leave old calls commented) and write
61        to globalFile when parameter globalFiles is set to True.
62      - switch on useSingleCpuIO in AD experiments: global_ocean.90x40x15 & isomip.
63    o pkg/autodiff:
64      - adread_adwrite.F: add a hack for RS arrays (when RS=real*4);
65        with ALLOW_AUTODIFF_WHTAPEIO defined, since corresponding (real*4) is
66        missing, just add a STOP if array type do not match.
67    o pkg/exf:
68      - to allow to use seaice-fraction from pkg/exf in other pkgs than pkg/seaice:
69         rename CPP option EXF_ALLOW_SEAICE_RELAX to EXF_SEAICE_FRACTION
70         and rename array obsSIce to exf_iceFraction.
71    o tutorial_deep_convection:
72      - add 1rst version of isotropic 3-D Smagorinsky code (from Louis-Philippe),
73        for now all in this exp. code dir.
74      - add secondary test using Smag-3D viscosity (keep very low backgroud visc for
75        testing) and flux-limter advection scheme for Temp. (no explicit diffusion).
76    o eesupp/src:
77      - added SINGLE_DISK_IO option because reading of parameter files on
78        very large number of processors did not work with existing set-up
79    
80    checkpoint64o (2013/09/25)
81    o pkg/atm_phys & atm_compon_interf:
82      - allows for coupling of gray-atmosphere (atm_phys) with ocean.
83    o tools/build_options:
84      - switch from "-fPIC" to "-mcmodel=medium" in optfiles: linux_amd64_gfortran
85        & linux_amd64_ifort11 and in linux_amd64_g77 & linux_amd64_open64 also
86        remove CPP setting (was identical to genmake2 default).
87    o pkg/gmredi & model/src: Some updating and work done on the residual model.
88      - created new file model/src/calc_eddy_stress.F to calculate the eddy stress.
89      - fixed up the calculation of the eddy stress and how it is added to the
90        external forcing via taueddy_external_forcing.F
91      - at the moment, it is very experimental and only works with the variable eddy
92        diffusivity calculated in gmredi_k3d.F
93    o pkg/seaice/seaice_check.F: add a check to catch the case of specifying
94        lw/swfluxfile instead of lw/swdownfile in data.exf together with pkg/seaice
95    o testreport (& tools/do_tst_2+2):
96      - for MPI test, set default COMMAND to 'mpirun -v -np TR_NPROC ./{executable}'
97    o tools/build_options: linux_amd64_gfortran & linux_amd64_ifort11:
98      - remove CPP='cpp -traditional -P' (this is genmake2 default)
99      - add switch (for big setups) to use 'medium' memory-model (but leave it
100        commented out for now). Note: needed with FC 19 to compile big setups.
101    o pkg/atm_compon_interf:
102      - regroup per field origin (model & pkgs) the coupling storage routines
103         (which accumalate in time each coupling field)
104      - move bi,bj loops inside atm_store_my_data.F and store also wind-stress;
105        update accordingly + simplify aim_do_physics.F
106    
107    checkpoint64n (2013/08/26)
108    o pkg/bbl:
109      - update formulation to reduce dispersion of tracer properties in bbl
110      - replaced horizontal and vertical transport parameters with velocities
111      - changes results for verification/global_with_exf.yearly
112    o verification/halfpipe_streamice:
113      - change to matrix construction; update both Fwd & AD output.
114    o verification/tutorial_tracer_adjsens:
115      - OpenAD test: switch to vector-invariant momentum since fluxform with
116        rStar causes problems with OpenAD; update output.
117    o tools:
118      - genmake2: define a common prefix for all temp-file names ; move them
119        to local /tmp disk (but would be easy to move them back);
120      - xmakedepend: apply the same switch for temp-files.
121    o pkg/offline:
122      - changes for use with rStar (NLFS): assume that we continue to provide
123        UVELMASS/hFacW_ini & VVELMASS/hFacS_ini (hFacWi,S_ini as written in grid
124        output files) and apply r* scaling at each time-step (function of the time
125        varying Eta field); use normal pickup files (needed for restart with NLFS).
126    o adjoint with OpenAD:
127      - move OpenAD-specific files from verification/OpenAD/code_oad_all to a new
128        package openad.  This package has to be compiled for all runs with OpenAD
129        instead of specifying code_oad_all as a modification directory.
130      - link the fortran templates from tools/OAD_support to the build directory
131        for preprocessing to avoid conflicts between different setups compiled
132        simultaneously and simplify cleanup.
133    o pkg/exf:
134      - in exf_getforcing.F: comment out most of the EXCH calls (fields used by
135        main model or other pkgs are exchanged in EXF_MAPFIELDS).
136    o model/src:
137      - do_stagger_fields_exchanges.F: skip EXCH calls when using pkg/offline
138        (similar to do_fields_blocking_exchanges.F).
139    o tools/genmake2:
140      - remove TAF output src code just before calling staf (when not doing a fresh
141        built, will stop if things go wrong with staf).
142      - fix target "adobj" (left from TAF version-2 transition)
143    o pkg/diagnostics:
144      - add a parameter to track the status of pkg/diagnostics activation;
145        this replace/extend the use of logical param "settingDiags" (to check
146        when adding diag to the list) to also check any DIAGNOSTICS_[]FILL* call.
147        New S/R to print error message and stop when pkgStatus is not right.
148      - to try: add a warning when "data.diagnostics" exist but useDiagnostics=F.
149    
150    checkpoint64m (2013/08/13)
151    o model/inc:
152      - move FCORI_MACROS.h from PARAMS(_MACROS).h to GRID_MACROS.h (left from
153        8 yrs ago modif when Coriolis arrays were moved from PARAMS.h to GRID.h)
154    o pkg/kpp & aim_v23:
155      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
156    o pkg/seaice:
157      - restore (last time on 2011/12/24) ability to compile pkg/seaice with
158        undefined pkg/exf ALLOW_ATM_TEMP or ALLOW_RUNOFF CPP-options.
159      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
160    o eesupp/src:
161      - fix check for overlap-size argument (myOLn.GT.MAX_OLY_EXCH)
162        in exch1_rx[_ad].template (thanks to Francois Lefeuvre report).
163    o switch to TAF version-2:
164      - add flow directives to "freeze" naming convention for ad-routines that
165        are used in I/O routines of adjoint state and associated common blocks
166        that are used in adcommon.h (backward compatible with version-1)
167      - update all ad-optfiles (in tools/adjoint_options + few local to some
168        verification exp) to switch to latest TAF version (currently 2.5.5);
169        merge "*_mpi" adoptfiles into the corresponding non-mpi (but commented
170        out except for diva).
171      - the major change with TAF version-2 is that both the differentiated
172        routines and the forward routines (new) are returned as part of the TAF
173        output source code. Update genmake2 accordingly.
174      - new output for AD experiment tutorial_global_oce_biogeo (better AD gradient
175        with version-2 when compared to TLM or FWD gradient); other experiments
176        output show minor changes (machine truncation level); update the few AD &
177        TLM output with 12 matching digits only (some prior to version-2 switch).
178    
179    checkpoint64l (2013/08/05)
180    o model/src:
181      - in dynamics.F, skip the call to CALC_VISCOSITY if momViscosity=F
182      - main_do_loop.F: no longer includes additional (AUTODIFF) header files
183        when using TAF but only if using OpenAD.
184    o pkg/mom_common+fluxform+vecinv:
185      - always set horiz. viscosity arrays to background value before calling
186        MOM_CALC_VISC (in MOM_FLUXFORM & MOM_VECINV) and call S/R MOM_CALC_VISC
187        only when using variable horiz. viscosity (useVariableVisc=T);
188      - simplify mom_vecinv.F (only 1 block for momViscosity).
189    o pkg/mom_common: variable horiz. viscosity in NH code
190      - move horiz-viscosity 3-D arrays viscAh_W & viscA4_W (used in calc_gw.F)
191        from model/inc/NH_VARS.h to pkg/mom_common/MOM_VISC.h
192      - store in common block (in MOM_VISC.h) logical parameters: useHarmonicVisc,
193        useBiharmonicVisc & useVariableVisc.
194      - fix old bug (already in 1rst implementation of variable horizontal viscosity
195        in calc_gw.F, version 1.27, 2006/06/20):
196        horizontal bi-harmonic viscosity in gW was missing when wiscA4W=0
197        even if variable bi-harmonic viscosity (e.g., viscA4Grid) was non-zero.
198      - change background horiz viscosity in vertical momentum (gW) to always be
199        viscAhW,viscA4W (instead of switching to viscAhD, viscA4D when using
200        any type of variable viscosity, e.g., viscAh/4Grid)
201      - change default value of viscAhW,viscA4W to viscAhD,viscA4D (instead of
202        viscAh,viscA4) which default to viscAh,viscA4 :  this avoid missing
203        horiz. viscosity in W eq when just setting viscAhD/Z,viscA4D/Z (since
204        default viscAh,viscA4 is zero).
205    o model/src:
206      - extend length of drC & recip_drC from Nr to Nr+1.
207    o Divided Adjoint (DIVA) with MPI:
208      - genmake2: do not create local ./mpi_headers dir when no file to copy into.
209      - remove option ALLOW_DIVIDED_ADJOINT_MPI (replaced by ALLOW_DIVIDED_ADJOINT
210        and ALLOW_USE_MPI) from model/src code and from ECCO_CPPOPTIONS.h.
211    
212    checkpoint64k (2013/07/23)
213    o tools/OAD_support:
214      - avoid the need for file "oadtempflile" in insertTemplateDir.bash
215        and remove it from genmake2.
216    o tools/build_options:
217      - remove MPI_HEADER_FILES_INC setting (no longer used) and comment out
218        MPI_HEADER_FILES list (let genmake2 find the missing headers)
219    o verification/halfpipe_streamice:
220      - change to driving stress formulation; update both Fwd & AD output.
221    o tools/genmake2 and Divided Adjoint with MPI:
222      - remove default setting of MPIINCLUDEDIR from $MPIHOME (always been broken);
223      - only create local ./mpi_headers dir if using MPI and MPIINCLUDEDIR is set;
224      - add new variable (LOCAL_MPI_HEADERS, replace MPI_HEADER_FILES_INC) in
225        Makefile, which is set by genmake2, and check which mpi-headers are needed.
226        Note: need to update adjoint_options/adjoint_diva_mpi accordingly.
227      - update target "CLEAN" (to also remove ./mpi_headers/ dir).
228    o testreport:
229      - changes for Divided Adjoint Run: when file "run_ADM_DIVA" is present,
230        perform additional runs (number of additional runs is "add_DIVA_runs" taken
231        from file run_ADM_DIVA ; should match "nchklev_3" in file "code_ad/tamc.h").
232    o verification/lab_sea (AD test):
233      - change to test Divided Adjoint Run in this set-up (both standard AD test
234        and 2 secondary AD test: noseaice + noseaicedyn); drop the evp AD test.
235    o pkg atm_ & ocn_compon_interf:
236      - remove cpl_earlyExpImpCall=F option (was mainly a hack added for the old
237        staggerTimeStep implementation) and disable (retired) corresponding
238        parameter.
239    o pkg/offline:
240      - comment out unused field-array: ICEM, ConvectCount, hflx[01], icem[01];
241      - add S/R OFFLINE_CHECK to print offline parameter summary
242        and stop if loading a file that is not used;
243      - enable to calculate GMRedi tensor, KPP mixing and convective index
244        when the corresponding file(s) is/are not specified (but pkg is used).
245      - comment out resetting of monitorFreq (to endTime) since it still useful
246        for monitoring CFL numbers and checking offline fields.
247    o OpenAD:
248      - do not define OAD_DEBUG (in tools/adjoint_options/adjoint_oad) to get
249        smaller standard output) and generate new (smaller) output (on baudelaire
250        using gfortran with -ieee) for exp. tutorial_tracer_adjsens
251    o model/src:
252      - call EXTERNAL_FORCING_SURF outside bi,bj loops (in do_oceanic_phys.F),
253        (where external_forcing_adjust was called) and change list of arguments;
254      - merge external_forcing_adjust.F into external_forcing_surf.F
255      - put surface relaxation of SST & SSS in new S/R (forcing_surf_relax.F)
256        which also contains balancing surface relaxation (ALLOW_BALANCE_RELAX,
257        previously in file "balance_relax.F", now removed); remove corresponding
258        arrays in FFIELDS.h.
259      - EXTERNAL_FORCING_SURF is now called when using pkg/offline; implement
260        a hack for getting back surfaceForcingS (loaded from file) when using
261        ALLOW_OLD_VIRTUALFLUX (pkg/dic, in DIC_OPTIONS.h) in offline set-up.
262      - update output of AD test experiment global_ocean.cs32x15.seaice_dynmix
263        (was getting only 11 digits for AD-grad, due to different truncation
264         error in AD code).
265    
266    checkpoint64j (2013/07/04)
267    o pkg/offline:
268      - to enable the use of other features with pkg offline (e.g., obcs),
269        also call S/R DO_OCEANIC_PHYS in offline run - more modifs to come.
270      - comment out "allowFreezing" (now active) in 2 offline testing exp.
271    o pkg/exf ALLOW_RUNOFTEMP
272      - fix sign and make compatible with temp_EvPrRn .NE. UNSET_RL
273      - ahdded RUNOFTEMP test to verification/global_ocean.cs32x15/input.seaice
274      - changes verification/global_ocean.cs32x15/results/output.seaice.txt
275    o pkg/atm_phys:
276      - allows to add some damping on uVel,vVel (strength only function of k).
277    o verification, ad-tests:
278      - reduce length of the simulation for AD test: global_ocean.cs32x15.seaice,
279        global_ocean_ebm and offline_exf_seaice.thsice.
280    o verification/halfpipe_streamice:
281      - found a bug in s/r pkg/streamice/streamice_advect_thickness which caused
282        flux input boundary conditions to be ignored; a fix for this bug changed
283        verification results for forward test.
284      - add adjoint test.
285    o pkg/ptracers:
286      - allow to restart without SOM pickup (resetting SOM to zero).
287    o pkg/gmredi:
288      - New parameterisation for the calculation of K and (GM_PsiX,GM_PsiY) added.
289      - It uses mixing length theory and suppression by steering level effects to
290        calculate a diffusivity used in the Redi tensor (see Bates et al., submitted
291        to JPO, for more details).
292      - It also uses the diffusivity to calculate an eddy induced streamfunction
293        based on a PV closure (rather than a buoyancy closure as in GM).
294      - New files added to pkg/gmredi:
295        gmredi_k3d.F calculates the diffusivity for the Redi tensor and the eddy
296          induced overturning streamfunction (called from gmredi_calc_tensor)
297        gmredi_calc_eigs.F calculates the eigenvalues and eigenvectors required
298          for use in gmredi_k3d
299        gmredi_calc_urms.F calculates the the rms eddy velocity used to calculate
300          the eddy diffusivity
301    
302    checkpoint64i (2013/06/18)
303    o pkg/cheapaml:
304      - take src files from MITgcm_contrib/verification_other/offline_cheapaml/code
305        that enable the use of seaice (pkg/thsice thermo & pkg/seaice dynamics)
306        with pkg/cheapaml.
307    o utils/python: add subpackage for cubed sphere function, first example is
308        simple cs.pcol to plot 2D fields on a map
309    o pkg/streamice:
310      - This is a new package in MITgcm, which solves dynamic equations for ice
311         sheets and ice streams
312      - At the moment it is independent of atmosphere/ocean dynamics, or any
313        other physical packages in MITgcm, even ShelfIce (although it is anticipat-
314        ed that this will change)
315      - There is a new verification exercise that tests it, halfpipe_streamice,
316        evolves a 40x80 km ice stream/ice shelf (at coarse resolution) in a
317        rectangular embayment
318      - halfpipe_streamice is forward-only for now, will have TAF test soon
319      - for questions, email dgoldber@mit.edu
320    o pkg/thsice:
321      - fix filling of snow-precip diagnostic (SIsnwPrc) (left from the removing
322        of snowPrc from common bloc, on May 2nd, thsice_step_fwd.F revision 1.40);
323      - remove diagnostics 'SI_FrcFx' ( now identical to 'SI_Fract' with new
324         call sequence: ice-Thermo(thsice),ice-Dyn,ice-Advect );
325      - allow precip from pkg/cheapaml to make snow over seaice.
326    o pkg/cfc:
327      - move in separated header file (CFC_ATMOS.h) time-serie arrays of Atmos CFC
328      - remove atmos CFC 2-D arrays from common bloc (now local variables)
329      - change some hard-coded constant to run time parameter for reading and
330        and interpolating atmospheric CFC ; keep same default as previously.
331      - more flexible reading of Atmos CFC (number of records no longer hard-coded)
332      - put arguments in standard order: myTime, myIter, myThid
333      - use standard S/R GET_PERIODIC_INTERVAL for time interpolation of
334        atmospheric CFC ; fix for the case myIter < PTRACERS_iter0.
335      - fix calculation of surf tendencys for partial-cell and/or Non-Lin Free-Surf
336      - new routine to print summary of CFC params and check for consistency.
337    o pkg/seaice: add uice/vice to the parameter list of s/r seaice_advdiff,
338      similar to thsice_advdiff.
339      Note that for the B-grid case the routine parameters uc/vc are overwritten.
340    o pkg/cfc:
341      - change time interpolation for atmospheric CFC-11 (now same as for CFC-12);
342        update output (CFC-11) of experiment cfc_example and tutorial_cfc_offline.
343      - fix interpolation of atmphspheric CFC between Sorthern and Northern
344        hemisphere value.
345    o pkg/seaice:
346      - allow to use seaice dynamics without pkg/exf (e.g., using pkg/cheapaml)
347    o pkg/seaice: add Adams-Bashforth2 time discretization for ice dynamics;
348                  so far only for JFNK-solver, turn on with SEAICEuseAB2 = .TRUE.
349      - requires an additional time level that is stored in the pickup
350      - you can start with AB2 from a pickup without this time level with
351        pickupStrictlyMatch = .false.
352    
353    checkpoint64h (2013/05/26)
354    o pkg/cheapaml:
355      - replace one ()**.5 with SQRT + use temp var "cdu = tau/Du" (coare3_flux);
356        affect machine truncation (but exp cheapAML_box still pass with 13 digits).
357      - consistent treatment of uWind,vWind location: assume everywhere in
358        pkg/cheapaml that they are on C-grid (@ uVel,vVel location)
359        (Note: was already the case for Tair,Qair advection);
360        add option (INCONSISTENT_WIND_LOCATION) to recover old results.
361      - compute diabatic forcing only in the interior (excluding overlap regions)
362      - fill in array "Qsw" (for short-wave heating);
363      - add diagnostic for precip ; fill-in diagnostics for cheapAML state vars
364        before any update (consistent with MITgcm state var diagnostics);
365      - cheapaml_fields_load.F & cheapaml_init_varia.F : only fill outer edges if
366        non periodic ; + adjusted for uWind,vWind (C-grid).
367    o pkg/seaice:
368      - remove dependence of pkg/seaice versus pkg/exf (file: pkg/pkg_depend) and
369        add explicitly pkg/exf in experiments that currently use pkg/seaice.
370      - allows to compile pkg/seaice without pkg/exf.
371    o tools/OAD_support:
372      - use a local copy (ourRWCPinBd) to ensure index ourRWCP stays within bounds
373        of array "ourStepOf" in function rvNextAction (revolve.F90).
374    o pkg/aim_compon_interf renamed to pkg/atm_compon_interf
375      - change pkg name (to be used with other atmospheric physics pkg)
376        but by-pass CVS when making the new pkg so that we keep the CVS history.
377    o pkg/offline:
378      - call OFFLINE_FIELDS_LOAD from pkg/offline/offline_init_varia.F
379        (previously called from pkg/dic_surfforcing_init.F)
380    o model/src:
381      - re-order sequence of calls within packages_init_variables.F, using
382        standard order, except for:
383         DIAGNOSTICS_INIT_VARIA and OFFLINE_INIT_VARIA (called @ the top),
384         CTRL_MAP_INI and OBCS_INIT_VARIABLES (called @ the bottom)
385    o new pkg: atm_phys
386      - add entry point and source code (previously in contrib
387          verification_other/atm_gray/code_gray/) for new pkg "atm_phys"
388        (atmospheric physics pkg from P. O'Gorman and T. Schneider, JCl, 2008).
389      - re-order sequence of calls within packages_readparms.F,
390         packages_init_fixed.F and packages_write_pickup.F
391        (but skip packages_init_variables.F because of TAF issues).
392      - update contrib/*/atm_gray/ experiment.
393    o pkg/seaice (ITD code):
394      - simplify and fix the writing of pickup-files for ITD case
395    o pkg/seaice (ITD code):
396      - introduce floe size dependent lateral melt for ITD case;
397      - cleaning (avoid division by zero, change to f77 syntax, remove tabs)
398      - update seaice_itd experiment main output.
399    o pkg/thsice:
400      - remove snowPrc from common block THSICE_FLUX, in THSICE_VARS.h and
401        declared it locally (without bi,bj) in thsice_main.F & aim_do_physics.F;
402        changed accordingly pkg/atm2d.
403    
404    checkpoint64g (2013/05/01)
405    o pkg/exf ALLOW_RUNOFTEMP
406      - if defined,  river and glacier runoff temperature can be read-in from
407        runoftempfile; runoftempfile needs to have same format as runofffile
408    o pkg/thsice (& pkg/bulk_force):
409      - In case Energy-Reference-Level (ERL) is used (temp_EvPrRn=0), account
410        for energy content of Precip + RunOff & Evap (like with pkg/exf).
411      - change computation domain to always be the interior (without overlap).
412      - fix bug (wrong overlap) when using EXF and stressReduction > 0.
413    o verification/tutorial_global_oce_biogeo:
414      - add preliminary OpenAD setup (still has problems)
415    o pkg/seaice:
416      - turn some parameters for choosing the convergence criterion of
417        the inexact Newton method (JFNK) into runtime parameters for convenience
418      - clean up seaice_calc_viscosities.F: remove/retire two options for
419        SEAICetaZmethod (1,2), introduce area weighting for method 3; this changes
420        the results of lab_sea/input because a division has been replaced by
421        a multiplication with the reciprocal (sumNorm)
422      - modify offline_exf_seaice/input.dyn_jfnk/data.seaice to improve
423        convergence of solver (changes results, of course), and to test some
424        new features
425    o model/src:
426      - remove unused (since Aug 2006) S/R SET_WRITE_GLOBAL_PICKUP and its call.
427      - remove unused forcing field "dQdT" and associated parameter "dQdTFile".
428      - move forcing adjustment (balancing surface forcing) in specific S/R
429        where might also be applied exchanges (if needed) to forcing arrays.
430    o pkg/shelfice:
431      - allow to specify the Ice-Shelf mass per unit area (instead of
432        shelficeLoadAnomaly) and do the conversion from one to the other
433      - move loading from file of shelficeLoadAnomaly from SHELFICE_INIT_VARIA
434        to SHELFICE_INIT_FIXED: (a) avoid some TAF recompution issues and
435        (b) will be loaded in time (before calling INI_PRESSURE) in case it is
436        needed in phi0surf for initial pressure calculation when useDynP_inEos_Zc
437      - update isomip experiment forward output (get machine truncation error
438        from conversion shelficeLoadAnomaly -> shelficeMass -> shelficeLoadAnomaly)
439    o verification/offline_exf_seaice:
440      revise data.seaice in input.thermo and input_ad and update results accordingly
441        HO = 0.2, SEAICE_areaLossFormula = 2,
442        SEAICE_growMeltByConv = .TRUE.,
443        SEAICE_doOpenWaterMelt = .TRUE.,
444      Improve consistency with input.thsice and fix the spurious 500m ice corners
445    o verification/global_ocean.cs32x15:
446      - set Energy Reference Level to liq. water @ 0 degC: temp_EvPrRn=0.,
447        in icedyn (thsice+seaice-dyn) test and update output.
448    o verification/offline_exf_seaice:
449      - adjust list of tested variables (with testreport) and update
450        standard test output with better slection of monitored fields.
451    o pkg/cd_code:
452      - swtich off Adams-Bashforth on the 1rst iteration. Update output of
453        experiment lab_sea.hb87
454    o tools/genmake2:
455      - change default makedepend from the system default to tools/xmakedepend:
456        When no makedepend is specified, select tools/xmakedepend it the test pass,
457        otherwise select the system default (if exist and pass the test) or
458        try to build cyrus-makedepend ; stop if none of the 3 works.
459    o pkg/exf & pkg/thsice:
460      - In case Energy-Reference-Level (ERL) is used (temp_EvPrRn=0), account
461        for energy content of Precip + RunOff & Evap. Assumes:
462       1) Rain has same temp as Air.
463       2) Snow has no heat capacity (consistent with seaice & thsice pkgs)
464       3) Run-Off comes at the temp of surface water (with same Cp)
465       4) Evap over ocean is released to the Atmos @ surf-temp (=SST); should be
466        put directly into Latent Heat flux & should use water-vapor heat capacity.
467       5) Evap over snow/seaice (pkg/thsice) assumes constant Lf+Lv (consistent
468        with snow having no Cp) => water vapor is released to Atmos @ 0^oC (=ERL).
469    o pkg/seaice: simplify the use of CPP flags in JFNK-related files
470        (compile when SEAICE_ALLOW_JFNK is defined)
471    o pkg/thsice:
472      - fix oceanic flux diagnostics & timeave (left from new sequence of calls
473        implementation): move THSICE_AVE call after the advection (called directly
474        from thsice_do_advect.F).
475    o verification/global_ocean.90x40x15 and OpenAD:
476      New experiment for OpenAD is identical to the one in input_ad except that
477        multiDimAdvection=.FALSE.,
478      There is still an issue with this.
479    o pkg/thsice:
480      - account for ice velocity (ocean relative velocity) in turbulent heat flux
481        at the base of the ice; update output of global_ocean.cs32x15 (icedyn)
482        and offline_exf_seaice (main test).
483    
484    checkpoint64f (2013/03/31)
485    o verification/OpenAD:
486      - new (smaller, without OAD_DEBUG) output_oadm.txt generated using gfortran.
487    o verification/isomip, pkg/shelfice and OpenAD:
488      - add OpenAD setup to this exp and make shelfice package work with OpenAD
489    o verification/tutorial_global_oce_biogeo:
490      - update AD and TLM output after turning off ALLOW_FE (in DIC_OPTIONS.h)
491    o verification/offline_exf_seaice:
492      - replace adjoint experiment (now similar to fwd input.thermo/ setup).
493    o verification/tutorial_tracer_adjsens, pkg/ptracers and OpenAD:
494      - add OpenAD setup to this exp and make ptracers package work with OpenAD
495    o pkg/seaice/seaice_evp.F:
496       mask the asymmetric contribution of the ice-ocean stress (when
497       the turningAngle is non-zero) over open water to avoid stripes
498       in the EVP-solutions after many EVP-substeps. This does not change
499       the verification experiment (because turningAngle=0 in that experiment),
500       but will affect other EVP solutions with turningAngle.ne.0
501    o verification, AD & TLM output:
502      - new TAF version 2.3.10 (previously 2.3.8) add more parenthesis in multiple
503        additions and multiplications which affect results at machine truncation
504        level. Update few AD output (1D_ocean_ice_column, bottom_ctrl_5x5,
505        lab_sea.noseaicedyn & offline_exf_seaice) and TLM output
506        (1D_ocean_ice_column & tutorial_tracer_adjsens.som81) which had only 12
507        digits of matching.
508    o pkg/seaice:
509       modify lsr-algorithm so that it vectorizes AND converges by using a
510       "zebra" method: split vector loop into two with step size 2; this
511       solves a general convergence problem for the JFNK solver on a vector
512       computer. It has the potential to even improve convergence for
513       non-vector machines, but it does change the results so it is turned
514       off by default. To turn on define CPP-flags SEAICE_VECTORIZE_LSR and
515       SEAICE_VECTORIZE_LSR_ZEBRA in SEAICE_OPTIONS.h
516    
517    checkpoint64e (2013/03/05)
518    o pkg/ecco and several verification experiments:
519       Remove special versions of the_model_main.F, the_main_loop.F, forward_step.F
520       from ecco package, and revert to unified routine in model/src/
521       Adjust verification experiments accordingly, especially gloal_oce_llc90
522       Should conclude long-standing work by Gael to reconsile the_main_loop with
523       ECCO and will enable OpenAD's revolve loop in ECCO setup.
524    o pkg/generic_advdiff:
525      - implement compressible flow method for multi-dim advection (similar to
526        gad_som_advect.F); add new option "GAD_MULTIDIM_COMPRESSIBLE" (since
527        TAF generates many recomputations) to use it; no yet coded with implicit
528        vertical advection.
529      - change experiment advect_cs (new output) and advect_xy (same output)
530        to test compressible flow multi-dim advection.
531    o pkg/generic_advdiff:
532      - fix SOM advection for unusual cases (linear Free-Surf in r*, other
533        cases where linear Free-Surf is not @ k=1, e.g., useShelfIce)
534    o pkg/seaice:
535      - fix bug in the no-slip implementation in seaice_calc_strainrates.F, this
536        bug affects two verification experiments (lab_sea and lab_sea.hb87),
537        recover old (wrong) results by setting noSlipFac = 2. in
538        seaice_calc_strainrates.F;
539      - add another averaging method for etaZ (etaZmethod=3), a mix of 2 and 0
540      - add runtime parameter SEAICE_JFNKepsilon for that finite difference
541        gradient in the Jacobian times vector operation (s/r seaice_jacvec)
542      - fix line search in seaice_jfnk.F (s/r seaice_jfnk_update)
543    o pkg/seaice: reorganize seaice_lsr.F to be able to reuse more code:
544      - new subroutines seaice_lsr_tridiagu/v
545      - introduce loop bounds i/jmin/max to be able to use a restricted
546        additive Schwarz method, but not used for now.
547      - rename SEAICE_CALC_LSR_COEFFS into SEAICE_LSR_CALC_COEFFS
548      - use new subroutines seaice_lsr_tridiagu/v in s/r seaice_preconditioner
549    o OpenAD support
550       Reorganize S/R call for overall time-stepping loop to facilitate
551       OpenAD revolve loop replacement
552       (new S/R main_do_loop.F)
553    o model/src:
554      - add 3-D array 3rd dimension to argument list of S/R ADAMS_BASHFORTH2/3;
555      - pkg/cheapaml: remove local S/R ADAMS2d and use instead standard S/R
556        ADAMS_BASHFORTH2.
557    o pkg/cheapaml:
558      - add new parameter (default=F, same as before) to disable full domain
559        (including land) periodicity in X & Y dir.
560      - new S/R CHEAPAML_COPY_EDGES to copy relaxation field into edges of
561        prognostics field ; merge the 2 S/R cycle_2d_tracer and timestep_2d_tracer
562        into single S/R CHEAPAML_TIMESTEP.
563    
564    checkpoint64d (2013/02/17)
565    o pkg/monitor (angular momentum):
566      - do not add Eta contribution to the total AM if using rigid-lid;
567      - correct for Adams-Bashforth in zonal-wind part (instead of in AM_eta).
568      - horizontal discretisation: compute Zonal wind contribution separately for
569        each component (instead of from cell centered averaged) and use the 4
570        grid-cell corner averaged value of Omega*(R*cos_Phi)^2 in AM_eta part.
571      - Check that AM is conserved with linear dynamics (momAdvection=F and linear
572        FreeSurf) if using vectorInvariant momentum.
573    o model/src (horizontal grid):
574      - move initialisation of all horizontal grid arrays to null value
575        from specific horizontal grid S/R to main S/R INI_GRID;
576      - add 2 new arrays to project model C-grid velocity on to zonal direction
577        (similar to AngleCosC & -AngleSinC but at U and V point location) and
578        compute them in S/R CALC_GRID_ANGLES.
579    o pkg/seaice: replace a hard coded parameter by a runtime parameter
580        SEAICE_JFNK_tolIter
581    o pkg/seaice: introduce a restricted additive Schwarz (RAS) method in
582        preconditioner for JFNK (run LSR into the overlaps as far as possible,
583        i.e OLx/y-2, but overwrite the solution in the overlaps)
584      - extend loop range in seaice_calc_viscosity
585      - add new parameters SEAICE_OLx/y (default = OLx/y-2)
586      - add flexible loop ranges to seaice_preconditioner, seaice_calc_lsr_coeffs
587      - slightly modify loops in tridiagonal solver lsr-preconditioner
588      - by default remove the extra exchange in seaice_preconditioner with a
589        replacement of an undocumented CPP flag by SEAICE_PRECOND_EXTRA_EXCHANGE
590      - modify offline_exf_seaice so that old results without RAS are reproduced
591        for output.dyn_jfnk.txt
592      in seaice_fgmres.F (unrelated to RAS)
593      - add a cpp-flag option for a re-ordered mapping (potentially more
594        efficient), but because this changes the results, turn it off by
595        default
596      - replace the save statement by local common blocks
597    o utils/matlab:
598      - fix tile-offset in rdmnc.m when output was produced using EXCH2.
599      - update cs_grid/bk_line scripts to use load_grid.m (in utils/matlab)
600        instead of local script "load_cs.m".
601    o pkg/seaice:
602      - fix a serious bug in seaice_fgmres.F, s/r seaice_scalprod, connected
603        to the scalarProductMetric and the unrolling. By chance this does not
604        change the verification experiment, because of the particular domain
605        decomposition
606    o pkg/diagnostics:
607      - change default missing_value from UNSET_RL to -999.
608    o pkg/layers: improve vectorization of layers_fluxcalc.F
609      - step 1: split loops, make TatU/V 2D arrays. This alone reduces the cpu
610        time spent in this routine by more than a factor of 3 on an NEC-SX8
611      - step 2: replace search algorithm by a bisection algorithm found in
612        Press et al. Numerical Recipes in Fortran. This algorithm can be
613        vectorized and finds the correct bin in approx. log2(Nlayers) steps.
614        For now, use this algorithm only for TARGET_NEC_SX defined.
615      - moved the search algorithm into a separate subroutine, that is kept
616        within the same file for automatic inlining.
617      - modified catching potential errors
618    o pkg/ecco:
619      - add compile switches ALLOW_SHALLOW_ALTIMETRY and ALLOW_HIGHLAT_ALTIMETRY.
620    o model/src, pkg/autodiff, pkg/ctrl, pkg/grdchk :
621      - modifications for ALLOW_GENTIM2D_CONTROL
622      -- forward_step.F, the_main_loop.F : pass options and arrays for adjoint tapes.
623      -- load_fields_driver.F : add call to CTRL_MAP_GENTIM2D( myTime, myIter, myThid )
624      -- add xx_gentim2d0/1 in ctrl_ad_check_lev1_dir.h checkpoint_lev1_directives.h etc
625      -- use ctrl_swapffields.F (new) instead of exf_SwapFFields.F in ctrl_get_gen.F
626    o model/src:
627      - account for moist thermodynamics in (dry) potential temperature equation;
628        update results of experiments: aim.5l_cs (x2), fizhi-cs (std + aqualev)
629        and cpl_aim+ocn.
630      - also switch to standard compiler (gfortran, was using ifort previously)
631        for fizhi-cs experiments reference output.
632    o pkg/ctrl:
633      - 1st step toward generic time-varying control variable (2D) via CPP option
634        ALLOW_GENTIM2D_CONTROL
635      - note new namelist ctrl_nml_genarr in data.ctrl
636    o verification/global_ocean.cs32x15:
637      - switch off OLD_THSICE_CALL_SEQUENCE (both forward and AD code) to use new
638        thsice calling sequence and update "output.icedyn.txt" output file.
639    o pkg/ptracers:
640      - from Ryan A.: code to allow to restart a tracer at regular time interval
641        specifying a reset frequency and a reset-phase (for each tracers).
642    o pkg/thsice:
643      - implement new sequence of calls for thsice+seaice:
644          previously:   ice-Dyn,ice-Advect,ice-Thermo(thsice)
645          new sequence: ice-Thermo(thsice),ice-Dyn,ice-Advect
646      - allows (with temporary CPP option "#define OLD_THSICE_CALL_SEQUENCE"
647        in CPP_OPTIONS.h) to recover old sequence;
648      - update diagnostics for Intermediate State thsice diagnostics: now filled
649        just before advection (instead of just after advection in old sequence);
650      - update output of experiment offline_exf_seaice (standard test);
651      - in global_ocean.cs32x15 exp., postpone output.icedyn.txt update
652        by setting #define OLD_THSICE_CALL_SEQUENCE in CPP_OPTIONS.h
653    o pkg/aim_v23:
654      - use tiled array for aim_CO2 and surface wind speed for export to coupler;
655      - use standard pkg/mdsio routines to read & write CO2 pickup file;
656      - in-line S/R AIM_AIM2DYN_EXCHANGES in aim_do_physics.F;
657      - Implement new sequence of calls for seaice advection (with thsice and
658        seaice diffusion): do ice advection after ice-Thermodynamic (previously
659        was done before); change aim_do_physics.F (split the bi,bj loops block);
660      - use same CPP option (OLD_THSICE_CALL_SEQUENCE) to recover old sequence;
661    o pkg/thsice:
662      - add a missing EXCH of sIceLoad in thsice_main.F (ocean set-up) for the case
663        where just seaice diffusion is used without seaice-dynamics.
664    
665    checkpoint64c (2013/01/18)
666    o pkg/seaice:
667      - add a parameter JFNKres_tFac that can replace JFNKres_t
668        (= JFNKres_tFac*JFNKresidual before JFNK solver)
669      - add a line search option to the JFNK solver
670      - move update of u/vIce and computation of initial residual into a separate
671        routine (same file); makes the code a little easier to read (?)
672      - the line search requires computation of the residual and for some reason
673        I cannot do the update of u/vIce at the beginning of the Newton loop
674        without changing the results, so we move computation of the new residual
675        also to the end of the Newton loop, even without the line search
676    o pkg/mdsio:
677      - write missing value (corresponding to undefined array value) to meta files;
678        skip this if missing value is one (UNSET_RL would be a better value for the
679        case of undefined missing value but it's current the default missing-value);
680        Also update mdsio_read_meta.F (reading timeInterval & missing-value).
681    o pkg/exf & thsice:
682      - for diagnostics purpose, fill-up and update Qsw array (+ fill the
683        diagnostics) even when SHORTWAVE_HEATING is #undef;
684    o verification/cfc_example:
685      - turn on pkg/layers with pkg/diagnostics (to test pkg/layers and to
686        illustrate how to use it).
687    o verification/offline_exf_seaice:
688      in input: add SEAICErestoreUnderIce=.TRUE., and reduce size of forcing
689        files to only one time-record.
690      in input.thermo: narrow the 2 bands of low initial ice-concentration near
691        N & S edges; switch on SEAICErestoreUnderIce=T; use pkg/diagnostics for
692        snapshot output; same mcPheePiston value as in thsice with
693        surf-current=0.2m/s.
694      in input.thsice: similar set-up as in input.thermo (channel with same seaice
695        initial conditions).
696    o verification/cfc_example:
697      - update file "data" with more standard choice (default rotationPeriod,
698        exactConserv=T, reduce ivdc_kappa to 10, remove multiDimAdvection=F,
699        set deltaTFreeSurf to deltaTtracer) and update the output.
700    o pkg/layers:
701      - fix bolus part so that it compiles with #undef GM_BOLUS_ADVEC;
702      - ensure that "layers_bolus" is switched to False when useGMRedi=False.
703    o verification/offline_exf_seaice:
704      - set all {field}period to zero for constant-in-time forcing (not tested
705        anywhere else).
706    o verification/offline_exf_seaice:
707      - dyn_lsr  : use pkg/seaice S/R (instead of pkg/thsice) to advect sea-ice;
708      - dyn_jfnk : use pkg/thsice S/R (instead of pkg/seaice) to advect sea-ice.
709    o model/src:
710      - implement Finite-Volume method for (hydrostatic) presure gradient
711        from S.-J. Lin (QJRMS 1997), for atmosphere using sigma-coordinate.
712    o pkg/seaice: implement EVP* by Lemieux et al. (2012).
713      - In order to be compatible with the default EVP code, this requires changing
714        the EVP code around a little; and because any small change immediately
715        breaks the lab_sea.hb87 verification experiment, the reference output is
716        updated two times (each time the remaining aggrement was only 2 digits):
717        - after replacing 1/dt by 1*recip_dt with a precomputed recip_dt
718        - after replacing 1/(1+0.5*dt/tau) by a/(a+1), with a=2*tau/dt
719        The adjoint test lab_sea.evp also needed to be updated.
720      - Turn on EVP* by setting SEAICE_deltaTevp as before, and setting
721        SEAICEuseEVPstar=.true.; for EVP* SEAICE_deltaTevp does not need to be
722        a factor of SEAICE_deltaTdyn, and you can set the number of EVP steps
723        explicitly with SEAICEnEVPstarSteps (thereby overriding the default of
724        INT(SEAICE_deltaTdyn/SEAICE_deltaTevp)). Controlling EVP* is deliberately
725        kept obscure, because I need to test it a little more.
726    o pkg/cheapaml:
727      - fix few incorrect type (_RL/_RS) in subroutine calls.
728    o pkg/seaice:
729      - new S/R SEAICE_MAP_RS2VEC (similar to SEAICE_MAP2VEC) to map _RS arrays
730        to _RL vector; this fixes JFNK code when compiling with "-use_r4" option.
731    o model/src:
732      - add a warning if using select_rStar=2 with nonlinFreeSurf <> 4;
733        change (in input_ad*/data) select_rStar from 2 to 1 for AD verification
734        experiments global_ocean.cs32x15 & tutorial_tracer_adjsens (+ update output)
735    o pkg/cheapaml:
736      - replace "273.1 _d 0" by celsius2K in pkg/cheapaml/cheapaml.F and
737        update output of experiment cheapAML_box.
738      - store in CHEAPAML.h coeffs ssq[0:2] for saturation specific humidity,
739        and set them only in one place (cheapaml_readparms.F).
740      - replace "273.16 _d 0" by celsius2K & replace "3.14159 _d 0" by constant "PI"
741      - remove re-setting of main-model parameter "celsius2K" (in cheapaml_readparms)
742        and re-setting of cheapAML params "lath" & "p0" (in cheapaml_init_varia).
743    o model/src/the_main_loop.F:
744      - fix revision 129 : need both ALLOW_ECCO and ALLOW_ECCO_EVOLUTION.
745    o pkg/seaice:
746      - remove legacy branch code.
747      - retire SEAICE_GROWTH_LEGACY and SEAICE_CAP_HEFF accordingly.
748    o verification/*/code*/SEAICE_OPTIONS.h:
749      - remove documentation for retired CPP flags (SEAICE_GROWTH_LEGACY,
750        SEAICE_CAP_HEFF).
751    o pkg/cheapaml:
752      - use standard routine (S/R GET_PERIODIC_INTERVAL) to decide when it is time
753        to load new forcing fields.
754      - add missing "_d 0" where it's needed; + some editing (improve indentation).
755      - remove switch to "-r8" compiler option (no longer needed) in verification
756        cheapAML_box, keep same output (small trucation error differences).
757    o verification/offline_exf_seaice:
758      - add thermodynamics only test.
759    o verification/cheapAML_box:
760      - split the domain in 8 (2x4) tiles; add MPI and multi-threaded test;
761        keep same output (same 14 digits for cg2d).
762      - switch on "-r8" compiler option (some numerical values are missing
763        the "_d 0") and update output (only 6 digits for cg2d were preserved).
764    
765    checkpoint64b (2012/12/24)
766    o pkg/cheapaml:
767      - remove un-used variables (Qnet,EmPmR) from pickup files.
768      - store tendency of advected variables into cheapaml pickup file
769        and fix the AB-2 restart.
770    o verification/offline_exf_seaice and lab_sea adjoint:
771      - switch to new code (#undef SEAICE_GROWTH_LEGACY).
772      - switch to 4 time steps in offline, consistent with lab_sea.
773      - match parameters from SEAICE_GROWTH_LEGACY branch in data.seaice.
774      - update results after change of experiment seaice.
775    o pkg/seaice:
776      - remove option SEAICE_MULTICATEGORY; has been replaced with run-time
777        parameter SEAICE_multDim. Issue a warning if SEAICE_MULTICATEGORY is
778        still defined since SEAICE_multDim needs to be set to MULTDIM value (from
779        SEAICE_SIZE.h) to recover previous #define SEAICE_MULTICATEGORY default.
780    o model/src:
781      - add run-time parameter to select CG2D solver minimum-residual solution
782        (in case of a poor convergence).
783    o pkg/seaice/seaice_lsr.F
784      - move calculation of matrix coefficients into new
785        S/R SEAICE_CALC_LSR_COEFFS; for now this routine remains in the same
786        file; the main purpose of this change is to be able to reuse the code
787        in S/R SEAICE_PRECONDITIONER
788      - modify the computation of the residual so that the mass of sea-ice
789        is not used twice; this simplifies the calculations, but since
790        the residual is never used except when LSR_mixIniGuess.ge.4---and this is
791        not tested in testreport---this does not affect the testreport results.
792    o verification/seaice_obcs:
793      - disable SEAICE_GROWTH_LEGACY; reset input files to match those of
794        verification/lab_sea/input.salt_plume; changes results/output.txt*
795    o model/src:
796      - adapt quasi-hydrostatic formulation to work with p or p* coordinate.
797    o pkg/seaice:
798      - improve description of parameters in seaice_fgmres.F and start
799        cleaning up the code
800      - change name of SCALPROD to SEAICE_SCALPROD and modify meaning of
801        second argument
802      - add a metric based on grid cell area to SEAICE_SCALPROD; update
803        results of offline_exf_seaice.dyn_jfnk
804      - compute initial residual norm in seaice_jfnk based on SEAICE_SCALPROD
805    o pkg/aim_v23:
806      - fix an other bug in dissipation heating (grid-cell area was missing).
807    o model/src + pkg/seaice:
808      - add global (multi-tile) linear solver for pair of tri-diagonal system
809        along X and Y lines, respectively for U and V component.
810        Note: 1) MPI and cube-exchange not yet coded.
811            2) probably not accurate for poorly conditioned / large size problem.
812      - add option for SEAICE_LSR to use global (multi-tile) tri-diagonal solver;
813        default: not compiled and not used.
814    o pkg/seaice:
815      - first attempt at a multi-threaded fgmres solver for the JFNK solver:
816        introduce bi/bj loops and use global_sum_tile_rl instead of
817        mpi_allreduce in seaice_fgmres.F
818      - improve diagnostics output for fgmres solver (seaice_fgmres.F)
819      - replace a few unnecessary goto statements by if-blocks  (seaice_fgmres.F)
820      - add a verification experiment for JFNK in offline_exf_seaice
821    o verification:
822      - change (for now, only fwd test) offline_exf_seaice experiment:
823        use a re-entrant channel with idealized coastline (trapezoidal shape)
824        at southern boundary to explore seaice dynamics and thermodynamics
825        with simple forcing. Main set-up has dynamics+thermo and SST relaxation;
826        secondary test (input.thsice) use thermodynamics only with SST relaxation.
827      - add seaice-dynamics only secondary test using LSR and pkg/thsice advection.
828    o pkg/exf:
829      - disable "sstExtrapol" when Nr=1
830    o verification:
831      - add new experiment "cheapAML_box" (simple 1 layer set-up from Bruno Deremble)
832        to test pkg/cheapaml.
833    o pkg/aim_v23 & pkg/shap_filt:
834      - fix dissipation heating (erroneous gravity multiplication factor).
835    o pkg/seaice:
836      - remove unused field pressPre from jfnk solver
837      - rename two subroutines in seaice_preconditioner.F
838    o eesupp/src:
839       - S/R MDSFINDUNIT avoids reserved unit numbers (scrUnit1, eeDataUnit ...)
840    o pkg/seaice/seaice_preconditioner.F: fix preconditioner once again
841       - remove wrong parts of the rhs and the lhs (were in there
842         because I did not understand the concept of this preconditioner)
843       - add an exchange between u- and v-sweep. This increases communication
844         by a factor of two but improves the convergence of jfnk. Ideally,
845         one would like the u- and v-sweep to be independent. So far within
846         undocumented ifdefs
847       - reorganize the extra computations for printing the residuals
848    o tools/genmake2:
849      - comment out the "mpif.h" include in NetCDF test programm (for MPI built)
850        since it's not necessary (and was preventing to use MNC in some cases).
851    
852    checkpoint64a (2012/11/16)
853    o pkg/autodiff:
854      - improve pkg-internal logical parameter switch (inAd/inFwd mode) so that
855        autodiff_readparms.F no longer depends on calling order (within
856        packages_readparms.F) and no longer requires to include ${PKG}_PARMS.h):
857        rename param turnFreeDriftInAdMode to SEAICEuseFREEDRIFTswitchInAd
858        and change param SEAICEuseDYNAMICSinAdMode to SEAICEuseDYNAMICSswitchInAd.
859    o pkg/obcs:
860      - adding tidal velocity forcing capability to obcs
861        for usage example, see verification/seaice_obcs/input.tides
862    o pkg/seaice:
863      - turn the LSR-relaxation parameters WFAU/V into runtime parameters
864        SEAICE_LSRrelaxU/V
865      - introduce runtime parameter SEAICEetaZmethod (=0 by default)
866    o pkg/aim_v23:
867      - implement heating from friction (bottom friction and stratospheric drag).
868    o pkg/shap_filt:
869      - fix diagnostic "SHAP_dKE" (was 2 time smaller); implement heating from
870        dissipation but only for Shap_funct=2, active when addFrictionHeating=T.
871    o model/src:
872      - move AddMass common block from DYNVARS.h to FFIELDS.h; allow to read-in
873        time-constant addMass field from file (addMassFile);
874      - support for heating due to friction (and Kinetic Energy dissipation):
875        add option, run-time switch and 3-D field array + support code ; each pkg
876        or S/R can add heating contribution (if there is a sink of KE); the sum is
877        accounted for as a Temperature tendency term (EXTERNAL_FORCING_T).
878    o pkg/seaice:
879      - complete merge of ITD code into seaice_growth.F
880        from MITgcm_contrib/torge/itd/code/
881        no verification so far, but Torge Martin tested
882        "1-D test case and Beaufort set up;
883        deliver okay results after 1 model year."
884      - complete merge of SEAICE_SIZE.h into all relevant routines
885      - move computation of eta at Z-points into calc_viscosities
886        + introduce global field etaZ
887        + add different methods for computing etaZ, for now the old
888          method (simple averages of eta to Z-points) is hardwired
889        + replace etaMeanZ by etaZ in seaice_lsr, seaice_calc_residual,
890          seaice_preconditioner
891      - simplify computations for SEAICE_ZETA_SMOOTHREG
892      - seaice_preconditioner:
893        + replace one remaining press by pressLoc (mistake)
894        + adjust printing of residuals
895      - improve I/O of diagnostics of JFNK in seaice_jfnk.F:
896        + add (SEAICE.h) and rename some counters (initiliased in
897          seaice_init_fixed.F)
898        + add _BEGIN/END_MASTER (myThid)  around print statements
899        + print total number of iterations and failures over SEAICE_monFreq
900          interval to STDOUT
901      - move control over output-messages by fgmres to seaice_jfnk to save
902        some operations
903      - move resetting initial guess for fgmres outside of seaice_fgmres_driver
904        in order to make restarts with sol .ne. zero (fgmres with restarts)
905        (seaice_jfnk.F, seaice_fgmres.F)
906      - seaice_calc_l/rhs.F: replace maskW/S by maskInW/S; this fixes
907        a serious convergence problem when open boundaries are involved
908    o pkg/ggl90: fix computation of control volumes for the case of
909      ALLOW_GGL90_HORIZDIFF (probably not used very often): move control volumes
910      up half a grid cell from C-centered to W-centered (pointed out by C. Eden)
911    o pkg/seaice: simplify seaice_evp by avoiding use of extra fields u/vIceC
912    o pkg/autodiff
913      - Add inAdMode switch for SEAICEuseDYNAMICS:
914        SEAICEuseDYNAMICSinAdMode
915        (extend logic in ADAUTODIFF_INADMODE_SET)
916    o pkg/seaice
917      - Step 1 of merging ice-thickness distribution (ITD) code from
918        MITgcm_contrib/torge/itd/ (author: Torge Martin)
919        The code implements concept laid out in Thorndike et al. (1975);
920        code is enabled via CPP flag SEAICE_ITD
921        nITD (in SEAICE_SIZE.h) defines number of ice thickness categories;
922        code is not complete yet!!
923      - SEAICE_SIZE.h now included in almost all seaice routines
924    o verification (using seaice):
925      - switch back seaice-dynamics (+ lower SOLV_MAX_ITERS) in ADM exp.
926        global_ocean.cs32x15.seaice ; update results.
927      - compile B-grid dynamics in FW test exp 1D_ocean_ice_column ;
928      - compile C-grid dynamics with #define SEAICE_ALLOW_JFNK in FW test exp
929        offline_exf_seaice (previously compiling B-grid).
930    o pkg/exf:
931      - fix some STOP conditions in exf_check.F (from Aug 28, modifs did not allow
932        to specify neither just 1 comp of wind or wind-stress, nor no surface momentum
933        forcing): just replace CPP option ALLOW_ATM_WIND with run-time param useAtmWind.
934    o pkg/layers (adjust changes from Sept 19):
935      - do snap-shot output and fill diagnostics from inside iLa loop (layers_calc.F)
936        this allows to remove "layers_maxNum" dimension from all layers arrays.
937    o pkg/layers (adjust changes from Sept 19):
938      - remove ALLOW_LAYERS_OUTPUT ; fix snap-shot and time-ave output ;
939      - snap-shot extended to all type of layers (not just the 1rst type);
940      - remove layers variables when corresponding CPP option is undef.
941    o pkg/layers:
942      - rename pkg/layers variable and add new output (layer exist & un-weighted
943        velocity in layer)
944    o pkg/seaice:
945      - simplify (?) ocean-drag coefficent computations by using
946        the same routine in all three solvers (saves some code lines)
947      - remove global fields DRAGA and DRAGS from C-grid code and
948        declare them locally in lsr.F (the only place where they are
949        still used)
950      - update AD output of lab_sea.evp (very sensitive anyway).
951    o pkg/seaice: add Jacobian-free Newton Krylov solver for ice dynamics
952      (Lemieux et al. 2010, 2012). Turn on with the usual SEAICE_ALLOW_JFNK
953      and SEAICEuseJFNK=.true. A few things to note:
954      - involves a FGMRES, that is parallel but very inefficient,
955        because of many scalar products (global sums) in the Gram-Schmidt
956        orthogonalization method. Needs to be replaced. Original code
957        from J.-F. Lemieux
958      - preconditioner for FGMRES is a stripped down version of LSOR
959      - SOLV_MAX_ITERS is now used for LSOR as a solver and as a
960        preconditioner. For the preconditioner, the default is set to 10.
961      - Jacobian times vector is computed with finite differences
962      - marginally related to JFNK-solver: add a smooth regularization for
963        zeta with tanh that will improve convergence (Lemieux and Tremblay,
964        2009) for any implicit solver (not implemented for EVP because EVP
965        does not need this regularization in the first place). Define
966        SEAICE_ZETA_SMOOTHREG in SEAICE_OPTIONS.h to use.
967    o eesupp/src:
968      - check in genmake2 that intrinsic S/R flush is available.
969      - add S/R to flush IO unit (if intrinsic S/R flush is available)
970      - flush standard & error msg unit before MPI termination
971      - if debugMode, flush IO unit after printing msg
972    o pkg/ctrl:
973      - ctrl_unpack.F, ALLOW_GENARR3D_CONTROL code: fix missing argument in call
974        to ctrl_set_unpack_xyz.
975    
976    checkpoint64 (2012/10/09)
977    o pkg/shelfice
978      - in mom_fluxform.F, mom_vecinv.F:
979        CALL SHELFICE_V_DRAG(bi,bj,k,vFld,KE,KappaRU,vF,myThid)
980        Bug fix KappaRU -> KappaRV
981        does not change verification/isomip but may change other setups
982        (presumably constant KappaRU=KappaRV)
983      - fix diagnostics SHIU/Vdrag (thanks to Tom Millgate)
984    o pkg/obcs:
985      - fixed some indexing bugs in obcs_seaice_sponge.F
986      - added obcs relaxation subroutines for HSALT and HSNOW
987      - changes verification/seaice_obcs/results/obcs_seaice_sponge.F
988    o pkg/seaice:
989      - add "multicategory" parameterization for snow in analogy to ice,
990        default is off for now.
991    o pkg/obcs:
992      - added obcs_seaice_sponge.F for obcs relaxation of seaice variables;
993        see verification/seaice_obcs/input.seaiceSponge for example application.
994      - remove local commom bloc "OBCS_GLOBAL" in obcs_readparms.F and do all the OB
995        index setting by master-thread. This fix multi-threads Pb in previous modifs.
996    o pkg/layers :
997      - add diagnostics to pkg/layers
998      - move the meat of pkg/layers from layers_calc.F to layers_fluxcalc.F
999        (from R.Tulloch). Layers_calc.F now calls layers_fluxcalc.F accordingly.
1000    o pkg/generic_advdiff/gad_implicit_r.F :
1001      - fix ADVr diagnostics in case of both implicit vertical advection and diffusion.
1002    o pkg/seaice/seaice_growth.F:
1003      - fix SItflux diagnostics in virtual salt flux + balanceEmpmr case.
1004    o pkg/obcs:
1005      - change default setting of OBCS_UVICE_OLD from defined to undef;
1006      - use new parameter OB_indexNone for null index value (instead of hard-coded 0)
1007        in all pkg/obcs code and in other pkgs; remove k loop in obcs_check_depths.F;
1008      - pass OB_indexNone as (new) argument to S/R CTRL_MASK_SET_[X,Y]Z;
1009      - change OB null index value (OB_indexNone) to -99 ; this fix the problem
1010        with Southern & Western OB at a tile edge (at least in a simple set-up).
1011    o pkg/obcs:
1012      - change settings of OB index in case OB coincides with tile edge (shared by
1013        2 tiles), so that common OB location is registered by both tiles (instead of
1014        only 1). However, for Southern and Western OB, index value = 0 is not
1015        recognized as valid OB index (=default null value) and needs to be fixed.
1016      - modify accordingly OBCS_BALANCE_FLOW and OBCS_MONITOR (avoid double counting)
1017      - new parameter "OB_indexNone" for null index value (for now, still zero)
1018        to replace hard-coded null index value of zero.
1019    o pkg/exch2:
1020      - improve W2_USE_E2_SAFEMODE (faster) and W2_E2_DEBUG_ON:
1021        always check buffer-size (but outside the loop); move checking for valid
1022        index from W2_USE_E2_SAFEMODE to W2_E2_DEBUG_ON; in W2_E2_DEBUG_ON,
1023        print each tile and point connection only if |W2_printMsg|>= 2 and 3.
1024    o pkg/ctrl (pack & unpack):
1025      - in ctrl_pack.F & ctrl_unpack.F, use the same local file-name variable
1026        (locally defined) for different variables (+ remove the variable-specific
1027        file name in CTRL_GENARR.h). For now, only implemented for GENARR2/3D_CONTROL
1028        (to be extended to other local file names in ctrl.h).
1029    o pkg/flt:
1030      - add a FLT_Iter0 option (similar to PTRACERS_Iter0).
1031    o pkg/mdsio:
1032      - fix missing STOP in mdsio_readvec_loc.F (case ioUnit=0) when file is missing
1033    o tools/genmake2:
1034      - add similar dependences for target EXE_AD & EXE_FTL as we have for EXECUTABLE
1035        (added by Alistair in version 1.51 for building without make depend);
1036      - remove Header files list (H_SRC_FILES) from the dependence of targets
1037         ad_input_code.f & ftl_input_code.f (not clear why it was added in the first
1038        place in version 1.23): this save going through staf when unrelated header
1039        file has been modified.
1040       Note: for an intermediate target (e.g., ad_input_code.f or adtaf) without
1041        "make depend" step, still need to do "make links" before "make adtaf".
1042    o eesupp/src (+ few pkg src files) & genmake2:
1043      - finish to remove ALWAYS_USE_MPI in source code that TAF does not see;
1044      - no longer set ALWAYS_USE_MPI in Makefile (was done by genmake2).
1045      - improve genmake2 checking for ALLOW_${PKG} in CPP_OPTIONS.h files (distinguish
1046         upper/lower case ; account for space between "#" and undef/define)
1047    o pkg/flt (with exch2):
1048      - cleaning: fix so that it compiles; move remaining MPI calls out of flt_exch2.F;
1049      - simplify threads synchronisation; fix (many issues) multi-threaded with MPI.
1050    
1051    checkpoint63s (2012/09/05)
1052    o pkg/ecco:
1053      - remove #ifdef ALLOW_SMOOTH_CORREL3D brackets.
1054      - add more relevant #ifdef ALLOW_SMOOTH ones.
1055      - sort out useAtmWind, useSMOOTH, ctrlSmoothCorrel2D.
1056    o pkg/ctrl:
1057      - CTRL_OPTIONS.h : document CPPs related to smoothing; ALLOW_SMOOTH_CORREL2D/3D,
1058        ALLOW_CTRL_SMOOTH, ALLOW_SMOOTH_CTRL2D, ALLOW_SMOOTH_CTRL3D.
1059      - ctrl.h : document run time params doInitXX, doMainPack, doMainUnpack, doPackDiag,
1060        doSinglePrecTapelev (audodiff param!), ctrlSmoothCorrel2D (new) and
1061        ctrlSmoothCorrel3D (new).
1062        The added ctrlSmoothCorrel2D/3D replace the old ALLOW_SMOOTH_CORREL2D/3D CPP.
1063      - ctrl_readparms.F : initialise ctrlSmoothCorrel2D/3D and read from namelist.
1064      - ctrl_init.F ctrl_pack.F ctrl_unpack.F : switch off ustress/vstress
1065        controls when useAtmWind, and vice versa.
1066      - ctrl_map_ini_ecco.F : UVEL0, VVEL0, edtaux, edtauy cannot be smoothed as tracers.
1067      - ctrl_get_gen.F : replace #ifdef ALLOW_SMOOTH_CORREL2D with
1068          #ifdef ALLOW_SMOOTH, IF ctrlSmoothCorrel2D, IF useSMOOTH.
1069      - ctrl_map_ini_gen.F : replace #ifdef ALLOW_SMOOTH_CORREL3D with
1070          #ifdef ALLOW_SMOOTH, IF ctrlSmoothCorrel3D, IF useSMOOTH.
1071      - ctrl_set_pack_xy[z].F, ctrl_set_unpack_xy[z].F:
1072        replace ALLOW_SMOOTH_CORREL2D/3D brackets with ctrlSmoothCorrel2D/3D.
1073    o pkg/smooth:
1074      - remove un-necessary includes.
1075      - remove ALLOW_SMOOTH*D and ALLOW_SMOOTH_CORREL*D brakets.
1076        Those CPP options were never defined, and not necessary.
1077    o model/src:
1078      - fix CPP brackets in ini_mixing.F (GM_background_K belongs to gmredi).
1079      - standard treatment of useSMOOTH.
1080    o pkg/autodiff:
1081      - add LOGICAL useGGL90inAdMode, useGGL90inFwdMode, useSALT_PLUMEinAdMode,
1082        useSALT_PLUMEInFwdMode allowing to switch off ggl90 and salt_plume adjoint.
1083    o pkg/exch2:
1084      - add "if usingMPI" where it was missing (in exch2_rx?_cube*.template)
1085        + start to remove ALWAYS_USE_MPI in source code that TAF does not see.
1086      - make new S/R W2_MAP_PROCS out of w2_eeboot.F to setup exch2 CommonFlag
1087        and tiles to process mapping.
1088      - re-arrange 3 header files (W2_EXCH2_PARAMS.h, _BUFFER.h & _TOPOLOGY.h)
1089        moving /EXCH2_FILLVAL_RX/ & /W2_EXCH2_COMMFLAG/ to W2_EXCH2_TOPOLOGY.h;
1090        rename "exch2_tProc" to "W2_tileProc" and move seting of e2FillValue_RX
1091        from w2_eeboot.F to w2_readparms.F.
1092    o eesupp/src:
1093      - set exchNeedsMemsync & exchUsesBarrier according to "usingMPI" (instead of
1094        ALWAYS_USE_MPI) + moved from ini_communication_patterns.F to eeset_parms.F;
1095        also move setting of exchCollectStatistics from exch_init.F to eeset_parms.F
1096      - in eedie.F and all_proc_die.F, always call MPI_FINALIZE when ALLOW_USE_MPI
1097        is defined (remove condition on usingMPI) to match cases where MPI_INIT
1098        has been called.
1099      - fix bug I put in previous modif of exch_sm_3d_rx.template (not much used);
1100      - change default (non-MPI) value of myPid (from 1 to 0) to match MPI settings
1101        (so that on 1 proc, get same myPid independently of usingMPI)
1102      - add a stop if multi-procs but usingMPI=F ; stop also if usingMPI=T and
1103        useCubedSphereExchange with EXCH-1 (safer).
1104      - add "if usingMPI" where it was missing (+ start to remove ALWAYS_USE_MPI).
1105    o pkg/ggl90:
1106      - fix bug in filling corner mask array "mskCor" (FILL_CS_CORNER_TR_RL call)
1107        used in ALLOW_GGL90_SMOOTH code.
1108    o pkg/flt:
1109      - fix typo in FLT_WITHOUT_Y_PERIODICITY (the effect was to ignore stopping
1110        floats at the Southern end of the domain).
1111    o eesupp/inc:
1112      - add a list of CPP-options which can be set by Makefile (DEF_IN_MAKEFILE.h);
1113        but not used (and not to be used) anywhere, just for documentation.
1114    o pkg/autodiff, exf, ptracers & seaice (AD & TL output):
1115      - comment out the very nasty "writeBinaryPrec = writeStatePrec" line, since:
1116        a) can damage previously written records in any other multi-record files.
1117        b) if needed, can easily do it cleanly, by calling S/R WRITE_REC_3D_RL/S.
1118    o tools/genmake2:
1119      - define variable MAKE within Makefile and use it in place of 'make';
1120      - update AD_CONFIG.h (if needed) before building any of the executable
1121        (forward, adjoint or tangent-lin); this involves a 2nd invocation of make;
1122        and add the usual #ifndef/#define AD_CONFIG_H in AD_CONFIG.h;
1123      - always print usual warning comment 'this file is automatically generated'
1124        from script convert_cpp_cmd2defines (+ remove this warning from genmake2).
1125    o pkg/cheapaml:
1126      - updated to correspond to the code used in accepted paper (Nico Wienders).
1127    o pkg/exf:
1128        added run time switch useAtmWind to replace ALLOW_ATM_WIND cpp switch.
1129        ALLOW_ATM_WIND now just sets the useAtmWind default (see exf_readparms.F)
1130        and force defines ALLOW_BULKFORMULAE (EXF_OPTIONS.h).
1131    o pkg/exf, autodiff, ctrl, ecco and seaice:
1132        remove ALLOW_ATM_WIND brackets, or replace them with useAtmWind ones.
1133    o pkg/ctrl, ecco:
1134        allow to compile both ALLOW_U/VSTRESS_CONTROL and ALLOW_U/VWIND_CONTROL.
1135        Depending on useAtmWind, one is inactive, and the other is active (see
1136        exf_getffields.F/exf_getsurfacefluxes.F).
1137    o tools/genmake2:
1138      - improve error msg when failing in 2nd test of check_for_broken_Ff
1139      - fix option '-makefile' short-name (-mf according to genmake2 -help)
1140      - source local config file "genmake_local" just after processing the genmake2
1141        command arguments (previously done before processing arg).
1142    o pkg/grdchk:
1143      - add a call to TURNOFF_MODEL_IO for Tangent-Linear run (in this case, call
1144        to this routine from cost_final has been dropped in g_cost_final)
1145      - improve printed information (more explicit msg, no longer using "print *,"
1146         fix fcpertminus printed value).
1147    o model/src:
1148      - move call to COST_INIT_VARIA out of packages_init_variables.F directly
1149        into initialise_varia.F (just after calling PACKAGES_INIT_VARIABLES):
1150        this prevents getting cost-funct reset in adinitialise_varia recomputations.
1151    o pkg/dic:
1152      - move initialisation of "freefe" array from from dic_biotic_forcing.F to
1153        fe_chem.F: this prevents TAF from dropping this initialisation in TLM code.
1154    o pkg/grdchk:
1155      - grdchk_main.F : added CALL GLOBAL_SUM_INT( ierr , myThid )
1156      - grdchk_getadxx.F etc. : omit I/O if ierr.EQ.0
1157    o pkg/autodiff/ctrl/grdchk :
1158      - attempt to sort out what works and what does not,
1159        with regard to I/O, and to warn/stop accordingly.
1160    o pkg/grdchk:
1161      - attempt to fix grdchk in the case of useSingleCpuIO.
1162      - "if ( myProcId .EQ. grdchkwhichproc .AND. ierr .EQ. 0 )"
1163       statements were moved from grdchk_main.F and into
1164       grdchk_getadxx.F grdchk_getxx.F grdchk_setxx.F.
1165      - a global sum is applied to record numbers icvrec/layer
1166       out of grdchk_loc so that they be passed to I/O routines.
1167    o pkg/smooth:
1168      - fix recomputation that appeared with nlfs : use smooth_recip_hFacC,
1169        smooth_hFacW, smooth_hFacS (copied at init_fixed) in 3d case.
1170    o verification/testreport:
1171      - add option '-tlm' for Tangent-Linear test (-adm,-oad,-tlm are all exclusive);
1172      - can also use compressed (gzip) reference output file;
1173      - change format (in pkg/grdchk) of TLM output (+ add forward gradient)
1174        to be easier to collect by testreport.
1175      - update existing TLM output (half out-of-date by more than 3 yrs).
1176      - report NETCDF & LAPACK settings (from genmake2) in output dir.
1177      - report run-time in each individual summary (previously only for AD test);
1178        for TLM test, add also TAF version.
1179      - add daily TLM test on (old) aces cluster + weekly test on baudelaire.
1180    
1181    checkpoint63r (2012/08/15)
1182    o tools/genmake2:
1183      - fix Makefile for target ftlall (+ update files to clean after make ftlall)
1184    o pkg/ecco/ecco_cost_final.F :
1185      - fix fc print statements (to stdout and costfunction0000) so
1186        that the printed value is always after the global sum.
1187    o pkg/seaice/seaice_dynsolver.F :
1188      - fix ice strength assymptote at SEAICE_area_max<1
1189        (no change for the standard case of SEAICE_area_max=1)
1190    o some cleaning:
1191      - pkg source files: ensure that all *.F files from each pkg included the
1192        corresponding ${PKG}_OPTIONS.h file (except stand-alone src file which
1193        only includes CPP_EEOPTIONS.h); fix S/R CTRL_SMOOTH ; update AD experiment
1194        code_ad/*.F src files; add new option-file in pkg/admtlm + corresponding
1195        includes;
1196      - model/src: add PACKAGES_CONFIG.h wherever ALLOW_AUTODIFF[_TAMC] is used.
1197      - ALLOW_DIFFKR_CONTROL: add a stop in S/R CTRL_CHECK in case ALLOW_3D_DIFFKR
1198        is undef; also define /DYNVARS_DIFFKR/ common block in DYNVARS.h when
1199        ALLOW_DIFFKR_CONTROL is defined, to allow to compile and reach this stop.
1200      - update option-file CPP_OPTIONS.h of all AD experiments:
1201        * no longer include PACKAGES_CONFIG.h ;
1202        * includes ECCO_CPPOPTIONS.h if PACKAGES_CONFIG.h has been included ;
1203        * def/undef ALLOW_3D_DIFFKR independently of ALLOW_DIFFKR_CONTROL (before
1204          including ECCO_CPPOPTIONS.h).
1205    o pkg/cost, pkg/ctrl, pkg/ecco option-file:
1206      - clean-up and split content of old pkg/ecco/ECCO_CPPOPTIONS.h file into
1207        separated pkg option-file (done according to old doc from ECCO_CPPOPTIONS.h,
1208        not necessary accurate).
1209      - add a template for option-file ECCO_CPPOPTIONS.h, mostly empty, in
1210        pkg/autodiff, i.e., the 1rst pkg to compile for adjoint built, with lines to
1211        deliberately break compilation (a remainder that it needs to be customized)
1212      - in pkg/ecco, includes ECCO_OPTIONS.h instead of COST_OPTIONS.h
1213      - rename COST_CPPOPTIONS.h to COST_OPTIONS.h
1214      - rename CTRL_CPPOPTIONS.h to CTRL_OPTIONS.h
1215    o tools/genamke2:
1216      - check for lapack.
1217    o pkg/cost and pkg/ecco : attempt to sort out some of the limiting intricacies.
1218      - pkg/cost.cost_final.F : allow for use of pkg/ecco and pkg/cost cost functions
1219        jointly. The exclusive ifdefs were removed, to add costs terms (when defined)
1220        from both packages.
1221      - the fc global sum in pkg/ecco/ecco_cost_final.F was removed accordingly.
1222      - for objf_atl we use either the pkg/ecco or the pkg/cost term depending on CPPs.
1223      - pkg/ecco and model/src : add CPP brackets around pkg/cost and pkg/ctrl includes
1224        of "CTRL_SIZE.h" "ctrl.h" "ctrl_dummy.h" "optim.h" / "cost.h" accordingly.
1225    o pkg/cost : add comments to explain special and/or untested setups.
1226    o pkg/exf:
1227      - use EXF_OPTIONS.h to set pkg/exf options except if done in ECCO_CPPOPTIONS.h
1228        (previously, ALLOW_AUTODIFF_TAMC was controling this switch).
1229    o verification/*/code_ad:
1230      mimimal cleaning of AD experiments ECCO_CPPOPTIONS.h option-file:
1231      - reccord when this file is included (define ECCO_CPPOPTIONS_H)
1232      - remove the most obvious obsolete features (e.g., #define ALLOW_COST not
1233        allowed since Oct 2003 in any option-file except in PACKAGES_CONFIG.h)
1234    o pkg/seaice :
1235      - added possibility to change ice strength/PRESS0 relationship to
1236        HEFF, according to the following run time parameters
1237        SEAICEpresPow0 :: HEFF exponent for ice strength below SEAICEpresH0 (integer, >0)
1238        SEAICEpresPow1 :: HEFF exponent for ice strength above SEAICEpresH0 (integer, >0)
1239        SEAICEpresH0   :: HEFF threshold for ice strength            (m)
1240    o pkg/ggl90 :
1241      - added run time flag mxlSurfFlag to include the code that ensure
1242        mixing between first and second level (previously included as a comment)
1243    o verification/1D_ocean_ice_column/input_ad/data.autodiff :
1244      - add test of newly added dumpAdByRec=T option where
1245        we write all records to one file per variable.
1246    o verification/global_ocean.cs32x15/code_ad/CPP_OPTIONS.h :
1247      - switch to #define ALLOW_BALANCE_RELAX and ALLOW_BALANCE_FLUXES
1248        to check that this code is ok with taf and compiles in adjoint.
1249    o pkg/autodiff :
1250      - added run time param dumpAdByRec : ad dump format switch.
1251        If true then write all records to one file per variable.
1252        Else write one file per record (remains the default).
1253      - revise seaice_ad_dump.F and exf_adjoint_snapshots_ad.F accordingly.
1254    o pkg/seaice:
1255     - Added SEAICEuseTILT run time switch : if set to
1256       false then omit the tilt term in seaice dynamics.
1257     - Fix free drift calculation.
1258    o pkg/shelfice:
1259      When initializing SHELFICEDragQuadratic, set default to be
1260      consistent with shiCdrag in case SHELFICEuseGammaFrict is used,
1261      but retain option to set it independently
1262      (inconsistenty spotted by Veronique Dansereau)
1263    o eesupp/inc:
1264      - in EEPARAMS.h, add real-type constant for some frequently used simple number
1265         (0,1,2,1/2), with name explicitly referring to RS/RL type.
1266    o model/src:
1267      - move balancing of relaxation terms to new S/R balance_relax.F.
1268    o pkg/autodiff:
1269      re-write active I/O high-level (control) S/R:
1270      - rename  S/R ACTIVE_READ/WRITE_RL to ACTIVE_READ/WRITE_3D_RL
1271      - add 1 more argument (useCurrentDir) to replace the "_LOC" 2nd set of S/R.
1272      - use standard pkg/mdsio I/O routines (MDS_READ/WRITE_SEC_XZ/YZ  and
1273        MDS_READ/WRITE_FIELD); change loops to multi-threads.
1274      - update and merge active_file_control_slice.flow into active_file_control.flow
1275      - update the calls in lower level S/R (active_file.F, active_file_g.F and
1276        active_file_ad.F) keeping the argument list and function unchanged.
1277      - also update lower-level "_LOC" version (call same S/R with "useCurrentDir
1278        =.TRUE.") and remove high-level (control) _loc version (not called anymore).
1279      - new low-level active I/O routines, one for each type (RL/RS), for active var
1280        of various (XY,XZ,YZ) shape and level number (arguments: arrShape, myNr);
1281        fix ctrl_init_wet.F & ecco_cost_weights.F by calling the new S/R with the
1282        right type.
1283    o autodiff and RS=real*4:
1284      - call the right type (_RS instead of _RL) of S/R in few output S/R (pkg/exf
1285        ad-monitor and snapshots); disable arrType='RS' in mdsio_gl*.F ;
1286      - change argument type of 3-D mask argument to _RS to match type in the call
1287        (in seaice_cost*.F, ctrl_*_gen.F and *ctrl_bound.F); to be continued.
1288    o pkg/thsice:
1289      - re-anable balanceEmPmR when useSEAICE=T with useThSIce=T.
1290      - option to correct ocean fresh-water flux for imbalance of Atmos+Land
1291        fresh-water flux: uniform correction or proportional to local precip.
1292    o pkg/ctrl:
1293      - new header file CTRL_SIZE.h for parameters maxCtrlArr2D, maxCtrlArr3D
1294      - redefine CPP option ALLOW_BOTTOMDRAG_CONTROL to
1295                            ALLOW_BOTTOMDRAG_CONTROL_NONGENERIC
1296      - verification/hs94.1x64x5/ tests ALLOW_GENARR{2D,3D}_CONTROL
1297    
1298    checkpoint63q (2012/07/30)
1299    o pkg/autodiff:
1300      note about monitor and snap-shot of ad-variables:
1301      a) need to apply ADEXCH before monitor or output of ad-vars to include
1302       overlap contributions (was done for adjDump but missing for monitor).
1303      b) since ADEXCH implies adding overlap values to interior array, machine
1304       truncation error is expected when adding an ADEXCH call in the middle of
1305       the time-stepping (although mathematically identical).
1306      modifs:
1307      - fix some incorrect type (RL/RS, UV/scalar) in ADEXCH calls and ad-vars
1308        declaration (adEddyPsiX,adEddyPsiY in adcommon.h).
1309      - add new run-time params (dumpAdVarExch & mon_AdVarExch) to select how  to
1310        apply ADEXCH before monitor or snap-shot of ad-variables:
1311           =0 : no ADEXCH ; =1 : do ADEXCH ; =2 : apply ADEXCH on a local copy.
1312      - implement new method (copy+adexch) for snap-shot and monitor of main model
1313        ad-vars (initially not used by default -> output unchanged).
1314      - change default (set to 2) to use new method and update few output_adm.txt
1315        with accurate ad-monitor (global_ocean.90x40x15, tutorial_global_oce_biogeo
1316        and both tutorial_tracer_adjsens tests).
1317      - switch 2 global_ocean.cs32x15 AD-tests to AB-2 (seaice_dynmix & thsice)
1318        and turn off momDissip_In_AB in the 2 other (needed for stable AB-3).
1319    o pkg/ctrl:
1320      enable the use of a variable number (maxCtrlArr2D, maxCtrlArr3D) of
1321      generic control variables via
1322      #define ALLOW_GENARR2D_CONTROL and/or #define ALLOW_GENARR3D_CONTROL
1323      Only required customization should be S/R ctrl_map_ini_genarr.F
1324      (routine in repository contains example)
1325    o pkg/exf:
1326      - fix and refine checking of surface-relaxation setting when using EXF
1327    o verification (adjoint exp):
1328      - reduce length of simulation by half for experiment global_ocean.cs32x15
1329        (std, seaice & seaice_dynmix) and exp tutorial_dic_adjoffline; update output.
1330    o pkg/mom_common (mom_u/v_bottomdrag), pkg/shelfice (shelfice_u/v_drag)
1331      - replace if statements KE.ne.0 with KE.gt.0 to avoid sqrt of negative numbers
1332        of KE that can occur with aggressive optimization
1333      + put quadratic bottom drag calculation in separated loops (only done if
1334        using bottomDragQuadratic)
1335    o model/src: CG2D_NSA
1336      - clean-up:  stop if cg2dNormaliseRHS=T and AUTODIFF
1337         and replace GLOBAL_SUM calls with GLOBAL_SUM_TILE.
1338      - in test-exp that uses CG2D_NSA (bottom_ctrl & tutorial_tracer_adjsens),
1339         change cg2d residual target to be expressed in Wunits (=> do not normalise
1340         RHS ; this fix global_max Pb with TAF); update output.
1341    o verification/tutorial_tracer_adjsens:
1342       improve parameter consistency (and get rid of warnings):
1343       - use deltaTFreeSurf=deltaTtracer (better with NonLin FreeSurf);
1344       - switch Temp Adv Scheme from 81 to 80 (no limiter since theta < 0 is physical)
1345       - use staggerTimeStep (for stability) in som81; use default rotation period.
1346    o pkg/exch2:
1347      - with empty facet: fix compact-format (W2_mapIO=1) definition (was previously
1348        reset to 0 = 1 long line in X)
1349    o pkg/mdsio:
1350      - fix reading of dimensions from meta file for large-size domain
1351    o model/src:
1352      - fix saltIsActiveTr setting for IdealGas eosType (eosType is 6 character long);
1353      - to refine CS-grid check, add logical flag "hasWetCSCorners": true if using
1354        Cubed-Sphere Exch with CS-corners inside the domain;
1355        make new S/R INI_GLOBAL_DOMAIN from code in ini_linear_phisurf.F to calculate
1356        globalArea and to set hasWetCSCorners.
1357      - add warning if usingCurvilinearGrid and momAdvection in flux-form (missing
1358        metric terms); stop if hasWetCSCorners=T and momAdvection in flux-form.
1359      - re-activate the stop if useCDscheme and hasWetCSCorners=T (previously if
1360        useCDscheme and useCubedSphereExchange).
1361    o pkg/seaice/seaice_growth.F :
1362      - compute the SEAICE_DISABLE_HEATCONSFIX term accordingly
1363        for the (.NOT.useRealFreshWaterFlux).OR.(nonlinFreeSurf.EQ.0)
1364        when the previous code was not correct.
1365      - in all cases diagnoze the boundary condition mismatch to SIaaflux
1366      - in the case of useRealFreshWaterFlux.AND.(nonlinFreeSurf.GT.0) add
1367        that term to QNET (essentially to set the melt/freeze water to 0degC).
1368        when SEAICEheatConsFix is true, so that the ocean+ice budget heat is closed.
1369    o verification/global_ocean.cs32x15/input.seaice :
1370      - add SEAICEheatConsFix in data.seaice, ensuring closed ocean+ice heat budget.
1371      - add diagnostics (commented out) for budget test using my matlab codes (gcmfaces).
1372      - update results (output.seaice.txt) accordingly.
1373    o verification/lab_sea/input/data.seaice :
1374      - remove SEAICEheatConsFix, which is now be tested
1375        in global_ocean.cs32x15. The presently coded fix
1376        is only consistent with real fresh water + nlfs.
1377      - update results (output.txt) accordingly.
1378    o pkg/salt_plume: added diagnotic for salt tendency (oceSPtnd).
1379    o AD_CONFIG.h file:
1380      - in genmake2: remove "#undef ALLOW_ECCO_OPTIMIZATION" from AD_CONFIG.h;
1381      - remove #include "AD_CONFIG.h" from all included OPTIONS files and
1382        add it explicitly in each fortran src file where it is needed.
1383        motivation: header file AD_CONFIG.h is generated/modified after "make depend"
1384        thus introducing potentially wrong dependency; therefore, better to include
1385        it only where it's really needed, and after any other included OPTIONS file
1386        (less tempting to bring conditional includes according to ALLOW_ADJOINT_RUN
1387        or ALLOW_TANGENTLINEAR_RUN).
1388    
1389    checkpoint63p (2012/07/06)
1390    o pkg/autodiff:
1391      - rename S/R INI_AUTODIFF to AUTODIFF_INIT_VARIA ;
1392      - create new header file "AUTODIFF_PARAMS.h" for pkg/autodiff parameters
1393        which are now read from new parameter file "data.autodiff" (inAdExact
1394        previously in "data", use{KPP/GMRedi/SEAICE}inAdMode previously in data.pkg)
1395      - add file "data.autodiff" in all verification/*/input_ad/ directories.
1396      - add run-time parameter to turn On/Off SEAICEuseFREEDRIFT in adjoint/forward
1397        mode (used in global_ocean.cs32x15.seaice_dynmix test exp.)
1398    o verification/tutorial_tracer_adjsens/
1399      - add extra sub-verification which uses "SOM" advection scheme
1400        (2nd Order-Moment Advection Scheme, Prather Limiter) with
1401          #define GAD_ALLOW_TS_SOM_ADV in GAD_OPTIONS.h
1402        and in data:
1403          multiDimAdvection=.TRUE.,
1404          tempAdvScheme=81,
1405          saltAdvScheme=81,
1406    o model/src:
1407      - introduce ALLOW_BALANCE_RELAX which allow the removal
1408       of the global mean of relaxation terms by setting
1409       balanceThetaClimRelax and balanceSaltClimRelax
1410      - disable balanceEmPmR and balanceQnet in the case when useSeaice.
1411       This case is now treated appropriately in seaice_growth.F
1412    o pkg/seaice:
1413      - do balanceEmPmR and balanceQnet based on the net fluxes
1414        (SItflux) that enter the ocean+ice system rather than QNET
1415        and EMPMR. Works best in real fresh water.
1416      - SIatmFW, SIatmQnet, and SItflux computations had to be moved
1417        out of the diagnotics bloc, and stored in global arrays.
1418    
1419    checkpoint63o (2012/06/29)
1420    o vertical mixing schemes:
1421      - remove unused S/R CALC_BUOYANCY (left from branch-atmos merging)
1422      - replace computation of density (in Function STATE1, opps_calc.F) by a call
1423        to S/R FIND_RHO_SCALAR
1424      - pass sigmaR to S/R PP81_CALC, MY82_CALC (but not yet used) and to GGL90_CALC
1425        and use it for N^2 calculation in ggl90_calc.F (save 2 density computations);
1426        affects output (vermix.ggl90) at truncation level.
1427    o testreport:
1428      - change adjustment of SIZE.h for mpi+mth testing: preserve enough tiles
1429        (nSx,nSy) for the number of threads (from eedata.mth)
1430    o model/src:
1431      - remove 2nd set of calls at the top of initialise_varia.F (Adjoint part)
1432        related to Non_Lin Free-Surf or Bottom-Control (but not longer necessary).
1433    o verification/tutorial_tracer_adjsens/
1434      - compile with ALLOW_CG2D_NSA
1435      - run with nonlinFreeSurf=3
1436      - update reference output_adm.txt
1437    o tools/genmake2:
1438      - add "-DHAVE_NETCDF" to the DEFINES list when NetCDF is available ;
1439        refine usePROFILES switching off (only when NetCDF is not available).
1440    o verification (atmospheric set-up):
1441      - change eosType='IDEALGAS' to eosType='IDEALG' to match variable declaration
1442    o pkg/profiles : refine profiles and files handling.
1443    o model/src and pkg/ecco : introduce run-time switch usePROFILES.
1444    o model/src/the_main_loop.F, forward_step.F and pkg/exf/EXF_OPTIONS.h :
1445      - changes to use model/src/the_main_loop.F rather than the ecco version
1446        in ecco type adjoint runs.
1447    o model/src:
1448      - move computation of recip of grid distance & area from INI_MASKS_ETC to INI_GRID
1449      - move setting of h0Fac[C,W,S] from INI_LINEAR_PHISURF to INI_MASKS_ETC
1450      - update_masks_etc.F: rename SMOOTH*_R4,R8 function to the corresponding type (RS,RL)
1451    o model/src:
1452      - fix S/R UPDATE_CG2D for ALLOW_DEPTH_CONTROL case (was empty before);
1453        update output of test experiment bottom_ctrl_5x5.
1454    o pkg/generic_advdiff:
1455      - implement vertical bi-harmonic diffusion (for now, only for T & S and
1456        only explicitly).
1457    o verification/bottom_ctrl_5x5/
1458      update reference output (results changed quite some time ago,
1459      not sure when; but new reference results look ok in terms of grdchk)
1460    o verification/1D_ocean_ice_column/
1461      For verification purposes, the exact adjoint rather than an approx.
1462      should be used (e.g., to comare against F.D. or TLM).
1463      removed autodiff_inadmode*_ad.F routines in code_ad/
1464      Update results/ accordingly.
1465    o pkg/cal:
1466      - change cal_getdate.F so that output date is function of input time only
1467        (less ambiguous, not mixed up with input iteration number).
1468      - fix calendarDumps for non-zero phase-lag (S/R CAL_TIME2DUMP).
1469    o pkg/diagnostics:
1470      - implement calendarDumps also for stats-diags
1471      - implement calendarDumps also for snap-shot output (negative freq)
1472      - for now, ignores calendarDumps if non-zero phase-lag.
1473    
1474    checkpoint63n (2012/06/04)
1475    o model/src:
1476      - recompute rSurfW & S to ensure consistent column thickness (needed for rStar)
1477        between Sum_k(hFac*drF) and rSurf-rLow, for now only when using pkg/shelfice;
1478      - use h0FacC, W & S to compute hFac_surfC, W & S in calc_surf_dr.F (more
1479        similar to calc_r_star.F); update results of experiment internal_wave and
1480        tutorial_global_oce_in_p (affected @ truncation level).
1481    o pkg/shelfice:
1482      - add parameterisation of advective-diffusive flux into the ice shelf
1483        according to Holland and Jenkins (1999), eq.22-33, as suggested by Jan De Ryd
1484      - simply eps3/3a computation
1485    o eesupp:
1486     - add new CPP option (DISCONNECTED_TILES) to disconnect tiles (no exchange
1487       between tiles, just fill-in edges assuming locally periodic subdomain) and
1488       add corresponding exchange subroutines (EXCH0);
1489     - new CG-solver version (_EX0) for disconnected-tiles special case.
1490    o model/src (CG-solvers):
1491     - modify Single-Reduction version (CG2D_SR) in case cg2dMaxIters is reached
1492       (similar final residual output and max-Iter number as with standard version);
1493     - allows to store and use lowest-residual solution (standard & _SR versions);
1494     - cleaning up (remove old, commented out code, LETS_MAKE_JAM ...).
1495     - by default, also compile CG2D_SR version (define ALLOW_SRCG in CPP_OPTIONS.h)
1496    o eesup/src:
1497     - global_vec_sum.F cleaning: add a BARRIER ; update comments ; remove ndef
1498       ALWAYS_USE_MPI (no longer needed after fixing usingMPI settings - March 2012)
1499    o pkg/salt_plume added to lab_sea/input_ad.noseaicedyn
1500    
1501    checkpoint63m (2012/04/27)
1502    o pkg/shelfice:
1503     - account for partical cells in surface level below ice-shelf for hydrostatic
1504       pressure calculion (set uniformFreeSurfLev to F); update isomip experiments.
1505    o ad test experiments:
1506     - update and rename to "ad_optfile.local" local AD-optfile specific to a
1507       particular adjoint verification experiment (in verification/*/code_ad/)
1508    o pkg/seaice & pkg/exf:
1509     - Part two of ECCO-CLIVAR code merges.
1510       Completes merge of seaice area relax. code.
1511       Requires unified CPP option EXF_ALLOW_SEAICE_RELAX
1512       to be set in EXF_OPTIONS.h since this pkg controls its I/O
1513       (and avoids second CPP option in SEAICE_OPTIONS.h)
1514     - change default value of costIceStart & costIceEnd to a valid date.
1515     - add snowPrecip to HSNOW in seaice_growth
1516    o pkg/ptracers:
1517     - move ptracers summary and setup check into separated S/R ; add a check for
1518       valid PTRACERS_Iter0 value (error+stop or just warning).
1519    o pkg/cal (+ pkg/ecco):
1520     - avoid calling a S/R with 2 times the same arg (FWD: unless both are only used
1521       as input; and for AD, unless both are not differentiable (e.g., k index)).
1522    o model/src:
1523     - define internal flag "uniformFreeSurfLev" (=T when free-surface level-index
1524       is everywhere k=1) to speed-up some calculations (by pass kSurf reference);
1525       temporary set to usingZCoords value (to be changed to F when using shelfice).
1526     - hydrostatic pressure: implement partial cell near the surface also for
1527       Z-coordinates (for the case where uniformFreeSurfLev=F); replace test on
1528       usingZCoords with test on uniformFreeSurfLev where needed (in NonHyd code).
1529    o pkg/ctrl/ctrl_init.F:
1530     - add a formal parameter to s/r ctrl_init_rec to print
1531       xx_$(ctrl_valiable)_file for easier debugging
1532     - move call of cal_* routines into the if-block where they are really
1533       needed so that xx_$(ctrl_variable)_period can be 0 or -12 without having
1534       to specify a startdate
1535    o pkg/seaice:
1536     - update comments in SEAICE_OPTIONS.h (+ similar update of lab_sea/code and
1537       global_ocean.cs32x15/code versions).
1538     - turn on seaice Multi-category (in data.seaice, SEAICE_multDim=7) for
1539       verification experiment global_ocean.cs32x15.seaice and update results.
1540    o pkg/exf:
1541     - new S/R EXF_GETFIELD_START to return starting-time of a forcing field
1542       (according to useExfYearlyFields).
1543    o pkg/cal:
1544     - move calendar setting & summary (previously in cal_readparams.F) into new
1545       S/R CAL_INIT_FIXED to be called later in the initialisation process, once
1546       length of the simulation is set (after SET_PARMS call); This is an attempt
1547       to fix Pb when, e.g.: pkg/longstep, modifies the length of the run.
1548     - For safety: keep a record of pkg/cal parameter settings status
1549               to allow to STOP if one pkg/cal S/R is called too early.
1550     - add a stop in all basic pkg/cal subroutines if called before setting is done.
1551     - modify cal_getdate.F: stop when nothing was returned;
1552       if called with myIter=-1, simply retrun modelBaseDate (1,2 = startDate_1,_2);
1553       this allows to remove "cal.h" from seaice_read_parms.F & init_mnc_vars.F.
1554    
1555    checkpoint63l (2012/04/04)
1556    o pkg/bbl:
1557      - fix call to FIND_RHO_2D in bbl_calc_rho.F (case multi-tiles per proc);
1558        update global_with_exf output.yearly.txt file.
1559    o pkg/cal:
1560      - start to clean-up cal_set.F ; fix for the case where baseTime is non-zero.
1561      - remove 2 unsused and very short (1 line only) functions ;
1562      - remove unsused subroutines from AD-Diff list.
1563    o model/src:
1564      - start to implement clean wait to stop in initialization S/R (config_check.F,
1565         packages_check.F, ini_parms.F and pkg/obcs/obcs_check.F + pkg/mypackage)
1566    o folowing PRINT_MESSAGE changes:
1567      - remove reminder multiple print to the same file (STDOUT) when multi-threads.
1568  o pkg/bbl:  o pkg/bbl:
1569    - modification so it can work with z*    - modification so it can work with z*
1570    - replace deltaT with dTtracerLev(k) for asynchronous time stepping    - replace deltaT with dTtracerLev(k) for asynchronous time stepping
