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