4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o OpenAD:
8      - do not define OAD_DEBUG (in tools/adjoint_options/adjoint_oad) to get
9        smaller standard output) and generate new (smaller) output (on baudelaire
10        using gfortran with -ieee) for exp. tutorial_tracer_adjsens
11    o model/src:
12      - call EXTERNAL_FORCING_SURF outside bi,bj loops (in do_oceanic_phys.F),
13        (where external_forcing_adjust was called) and change list of arguments;
14      - merge external_forcing_adjust.F into external_forcing_surf.F
15      - put surface relaxation of SST & SSS in new S/R (forcing_surf_relax.F)
16        which also contains balancing surface relaxation (ALLOW_BALANCE_RELAX,
17        previously in file "balance_relax.F", now removed); remove corresponding
18        arrays in FFIELDS.h.
19      - EXTERNAL_FORCING_SURF is now called when using pkg/offline; implement
20        a hack for getting back surfaceForcingS (loaded from file) when using
21        ALLOW_OLD_VIRTUALFLUX (pkg/dic, in DIC_OPTIONS.h) in offline set-up.
22      - update output of AD test experiment global_ocean.cs32x15.seaice_dynmix
23        (was getting only 11 digits for AD-grad, due to different truncation
24         error in AD code).
25    
26    checkpoint64j (2013/07/04)
27    o pkg/offline:
28      - to enable the use of other features with pkg offline (e.g., obcs),
29        also call S/R DO_OCEANIC_PHYS in offline run - more modifs to come.
30      - comment out "allowFreezing" (now active) in 2 offline testing exp.
31    o pkg/exf ALLOW_RUNOFTEMP
32      - fix sign and make compatible with temp_EvPrRn .NE. UNSET_RL
33      - ahdded RUNOFTEMP test to verification/global_ocean.cs32x15/input.seaice
34      - changes verification/global_ocean.cs32x15/results/output.seaice.txt
35    o pkg/atm_phys:
36      - allows to add some damping on uVel,vVel (strength only function of k).
37    o verification, ad-tests:
38      - reduce length of the simulation for AD test: global_ocean.cs32x15.seaice,
39        global_ocean_ebm and offline_exf_seaice.thsice.
40    o verification/halfpipe_streamice:
41      - found a bug in s/r pkg/streamice/streamice_advect_thickness which caused
42        flux input boundary conditions to be ignored; a fix for this bug changed
43        verification results for forward test.
44      - add adjoint test.
45    o pkg/ptracers:
46      - allow to restart without SOM pickup (resetting SOM to zero).
47    o pkg/gmredi:
48      - New parameterisation for the calculation of K and (GM_PsiX,GM_PsiY) added.
49      - It uses mixing length theory and suppression by steering level effects to
50        calculate a diffusivity used in the Redi tensor (see Bates et al., submitted
51        to JPO, for more details).
52      - It also uses the diffusivity to calculate an eddy induced streamfunction
53        based on a PV closure (rather than a buoyancy closure as in GM).
54      - New files added to pkg/gmredi:
55        gmredi_k3d.F calculates the diffusivity for the Redi tensor and the eddy
56          induced overturning streamfunction (called from gmredi_calc_tensor)
57        gmredi_calc_eigs.F calculates the eigenvalues and eigenvectors required
58          for use in gmredi_k3d
59        gmredi_calc_urms.F calculates the the rms eddy velocity used to calculate
60          the eddy diffusivity
61    
62    checkpoint64i (2013/06/18)
63    o pkg/cheapaml:
64      - take src files from MITgcm_contrib/verification_other/offline_cheapaml/code
65        that enable the use of seaice (pkg/thsice thermo & pkg/seaice dynamics)
66        with pkg/cheapaml.
67    o utils/python: add subpackage for cubed sphere function, first example is
68        simple cs.pcol to plot 2D fields on a map
69    o pkg/streamice:
70      - This is a new package in MITgcm, which solves dynamic equations for ice
71         sheets and ice streams
72      - At the moment it is independent of atmosphere/ocean dynamics, or any
73        other physical packages in MITgcm, even ShelfIce (although it is anticipat-
74        ed that this will change)
75      - There is a new verification exercise that tests it, halfpipe_streamice,
76        evolves a 40x80 km ice stream/ice shelf (at coarse resolution) in a
77        rectangular embayment
78      - halfpipe_streamice is forward-only for now, will have TAF test soon
79      - for questions, email dgoldber@mit.edu
80    o pkg/thsice:
81      - fix filling of snow-precip diagnostic (SIsnwPrc) (left from the removing
82        of snowPrc from common bloc, on May 2nd, thsice_step_fwd.F revision 1.40);
83      - remove diagnostics 'SI_FrcFx' ( now identical to 'SI_Fract' with new
84         call sequence: ice-Thermo(thsice),ice-Dyn,ice-Advect );
85      - allow precip from pkg/cheapaml to make snow over seaice.
86    o pkg/cfc:
87      - move in separated header file (CFC_ATMOS.h) time-serie arrays of Atmos CFC
88      - remove atmos CFC 2-D arrays from common bloc (now local variables)
89      - change some hard-coded constant to run time parameter for reading and
90        and interpolating atmospheric CFC ; keep same default as previously.
91      - more flexible reading of Atmos CFC (number of records no longer hard-coded)
92      - put arguments in standard order: myTime, myIter, myThid
93      - use standard S/R GET_PERIODIC_INTERVAL for time interpolation of
94        atmospheric CFC ; fix for the case myIter < PTRACERS_iter0.
95      - fix calculation of surf tendencys for partial-cell and/or Non-Lin Free-Surf
96      - new routine to print summary of CFC params and check for consistency.
97    o pkg/seaice: add uice/vice to the parameter list of s/r seaice_advdiff,
98      similar to thsice_advdiff.
99      Note that for the B-grid case the routine parameters uc/vc are overwritten.
100    o pkg/cfc:
101      - change time interpolation for atmospheric CFC-11 (now same as for CFC-12);
102        update output (CFC-11) of experiment cfc_example and tutorial_cfc_offline.
103      - fix interpolation of atmphspheric CFC between Sorthern and Northern
104        hemisphere value.
105    o pkg/seaice:
106      - allow to use seaice dynamics without pkg/exf (e.g., using pkg/cheapaml)
107    o pkg/seaice: add Adams-Bashforth2 time discretization for ice dynamics;
108                  so far only for JFNK-solver, turn on with SEAICEuseAB2 = .TRUE.
109      - requires an additional time level that is stored in the pickup
110      - you can start with AB2 from a pickup without this time level with
111        pickupStrictlyMatch = .false.
112    
113    checkpoint64h (2013/05/26)
114    o pkg/cheapaml:
115      - replace one ()**.5 with SQRT + use temp var "cdu = tau/Du" (coare3_flux);
116        affect machine truncation (but exp cheapAML_box still pass with 13 digits).
117      - consistent treatment of uWind,vWind location: assume everywhere in
118        pkg/cheapaml that they are on C-grid (@ uVel,vVel location)
119        (Note: was already the case for Tair,Qair advection);
120        add option (INCONSISTENT_WIND_LOCATION) to recover old results.
121      - compute diabatic forcing only in the interior (excluding overlap regions)
122      - fill in array "Qsw" (for short-wave heating);
123      - add diagnostic for precip ; fill-in diagnostics for cheapAML state vars
124        before any update (consistent with MITgcm state var diagnostics);
125      - cheapaml_fields_load.F & cheapaml_init_varia.F : only fill outer edges if
126        non periodic ; + adjusted for uWind,vWind (C-grid).
127    o pkg/seaice:
128      - remove dependence of pkg/seaice versus pkg/exf (file: pkg/pkg_depend) and
129        add explicitly pkg/exf in experiments that currently use pkg/seaice.
130      - allows to compile pkg/seaice without pkg/exf.
131    o tools/OAD_support:
132      - use a local copy (ourRWCPinBd) to ensure index ourRWCP stays within bounds
133        of array "ourStepOf" in function rvNextAction (revolve.F90).
134    o pkg/aim_compon_interf renamed to pkg/atm_compon_interf
135      - change pkg name (to be used with other atmospheric physics pkg)
136        but by-pass CVS when making the new pkg so that we keep the CVS history.
137    o pkg/offline:
138      - call OFFLINE_FIELDS_LOAD from pkg/offline/offline_init_varia.F
139        (previously called from pkg/dic_surfforcing_init.F)
140    o model/src:
141      - re-order sequence of calls within packages_init_variables.F, using
142        standard order, except for:
143         DIAGNOSTICS_INIT_VARIA and OFFLINE_INIT_VARIA (called @ the top),
144         CTRL_MAP_INI and OBCS_INIT_VARIABLES (called @ the bottom)
145    o new pkg: atm_phys
146      - add entry point and source code (previously in contrib
147          verification_other/atm_gray/code_gray/) for new pkg "atm_phys"
148        (atmospheric physics pkg from P. O'Gorman and T. Schneider, JCl, 2008).
149      - re-order sequence of calls within packages_readparms.F,
150         packages_init_fixed.F and packages_write_pickup.F
151        (but skip packages_init_variables.F because of TAF issues).
152      - update contrib/*/atm_gray/ experiment.
153    o pkg/seaice (ITD code):
154      - simplify and fix the writing of pickup-files for ITD case
155    o pkg/seaice (ITD code):
156      - introduce floe size dependent lateral melt for ITD case;
157      - cleaning (avoid division by zero, change to f77 syntax, remove tabs)
158      - update seaice_itd experiment main output.
159    o pkg/thsice:
160      - remove snowPrc from common block THSICE_FLUX, in THSICE_VARS.h and
161        declared it locally (without bi,bj) in thsice_main.F & aim_do_physics.F;
162        changed accordingly pkg/atm2d.
163    
164    checkpoint64g (2013/05/01)
165    o pkg/exf ALLOW_RUNOFTEMP
166      - if defined,  river and glacier runoff temperature can be read-in from
167        runoftempfile; runoftempfile needs to have same format as runofffile
168    o pkg/thsice (& pkg/bulk_force):
169      - In case Energy-Reference-Level (ERL) is used (temp_EvPrRn=0), account
170        for energy content of Precip + RunOff & Evap (like with pkg/exf).
171      - change computation domain to always be the interior (without overlap).
172      - fix bug (wrong overlap) when using EXF and stressReduction > 0.
173    o verification/tutorial_global_oce_biogeo:
174      - add preliminary OpenAD setup (still has problems)
175    o pkg/seaice:
176      - turn some parameters for choosing the convergence criterion of
177        the inexact Newton method (JFNK) into runtime parameters for convenience
178      - clean up seaice_calc_viscosities.F: remove/retire two options for
179        SEAICetaZmethod (1,2), introduce area weighting for method 3; this changes
180        the results of lab_sea/input because a division has been replaced by
181        a multiplication with the reciprocal (sumNorm)
182      - modify offline_exf_seaice/input.dyn_jfnk/data.seaice to improve
183        convergence of solver (changes results, of course), and to test some
184        new features
185    o model/src:
186      - remove unused (since Aug 2006) S/R SET_WRITE_GLOBAL_PICKUP and its call.
187      - remove unused forcing field "dQdT" and associated parameter "dQdTFile".
188      - move forcing adjustment (balancing surface forcing) in specific S/R
189        where might also be applied exchanges (if needed) to forcing arrays.
190    o pkg/shelfice:
191      - allow to specify the Ice-Shelf mass per unit area (instead of
192        shelficeLoadAnomaly) and do the conversion from one to the other
193      - move loading from file of shelficeLoadAnomaly from SHELFICE_INIT_VARIA
194        to SHELFICE_INIT_FIXED: (a) avoid some TAF recompution issues and
195        (b) will be loaded in time (before calling INI_PRESSURE) in case it is
196        needed in phi0surf for initial pressure calculation when useDynP_inEos_Zc
197      - update isomip experiment forward output (get machine truncation error
198        from conversion shelficeLoadAnomaly -> shelficeMass -> shelficeLoadAnomaly)
199    o verification/offline_exf_seaice:
200      revise data.seaice in input.thermo and input_ad and update results accordingly
201        HO = 0.2, SEAICE_areaLossFormula = 2,
202        SEAICE_growMeltByConv = .TRUE.,
203        SEAICE_doOpenWaterMelt = .TRUE.,
204      Improve consistency with input.thsice and fix the spurious 500m ice corners
205    o verification/global_ocean.cs32x15:
206      - set Energy Reference Level to liq. water @ 0 degC: temp_EvPrRn=0.,
207        in icedyn (thsice+seaice-dyn) test and update output.
208    o verification/offline_exf_seaice:
209      - adjust list of tested variables (with testreport) and update
210        standard test output with better slection of monitored fields.
211    o pkg/cd_code:
212      - swtich off Adams-Bashforth on the 1rst iteration. Update output of
213        experiment lab_sea.hb87
214    o tools/genmake2:
215      - change default makedepend from the system default to tools/xmakedepend:
216        When no makedepend is specified, select tools/xmakedepend it the test pass,
217        otherwise select the system default (if exist and pass the test) or
218        try to build cyrus-makedepend ; stop if none of the 3 works.
219    o pkg/exf & pkg/thsice:
220      - In case Energy-Reference-Level (ERL) is used (temp_EvPrRn=0), account
221        for energy content of Precip + RunOff & Evap. Assumes:
222       1) Rain has same temp as Air.
223       2) Snow has no heat capacity (consistent with seaice & thsice pkgs)
224       3) Run-Off comes at the temp of surface water (with same Cp)
225       4) Evap over ocean is released to the Atmos @ surf-temp (=SST); should be
226        put directly into Latent Heat flux & should use water-vapor heat capacity.
227       5) Evap over snow/seaice (pkg/thsice) assumes constant Lf+Lv (consistent
228        with snow having no Cp) => water vapor is released to Atmos @ 0^oC (=ERL).
229    o pkg/seaice: simplify the use of CPP flags in JFNK-related files
230        (compile when SEAICE_ALLOW_JFNK is defined)
231    o pkg/thsice:
232      - fix oceanic flux diagnostics & timeave (left from new sequence of calls
233        implementation): move THSICE_AVE call after the advection (called directly
234        from thsice_do_advect.F).
235    o verification/global_ocean.90x40x15 and OpenAD:
236      New experiment for OpenAD is identical to the one in input_ad except that
237        multiDimAdvection=.FALSE.,
238      There is still an issue with this.
239    o pkg/thsice:
240      - account for ice velocity (ocean relative velocity) in turbulent heat flux
241        at the base of the ice; update output of global_ocean.cs32x15 (icedyn)
242        and offline_exf_seaice (main test).
243    
244    checkpoint64f (2013/03/31)
245    o verification/OpenAD:
246      - new (smaller, without OAD_DEBUG) output_oadm.txt generated using gfortran.
247    o verification/isomip, pkg/shelfice and OpenAD:
248      - add OpenAD setup to this exp and make shelfice package work with OpenAD
249    o verification/tutorial_global_oce_biogeo:
250      - update AD and TLM output after turning off ALLOW_FE (in DIC_OPTIONS.h)
251    o verification/offline_exf_seaice:
252      - replace adjoint experiment (now similar to fwd input.thermo/ setup).
253    o verification/tutorial_tracer_adjsens, pkg/ptracers and OpenAD:
254      - add OpenAD setup to this exp and make ptracers package work with OpenAD
255    o pkg/seaice/seaice_evp.F:
256       mask the asymmetric contribution of the ice-ocean stress (when
257       the turningAngle is non-zero) over open water to avoid stripes
258       in the EVP-solutions after many EVP-substeps. This does not change
259       the verification experiment (because turningAngle=0 in that experiment),
260       but will affect other EVP solutions with turningAngle.ne.0
261    o verification, AD & TLM output:
262      - new TAF version 2.3.10 (previously 2.3.8) add more parenthesis in multiple
263        additions and multiplications which affect results at machine truncation
264        level. Update few AD output (1D_ocean_ice_column, bottom_ctrl_5x5,
265        lab_sea.noseaicedyn & offline_exf_seaice) and TLM output
266        (1D_ocean_ice_column & tutorial_tracer_adjsens.som81) which had only 12
267        digits of matching.
268    o pkg/seaice:
269       modify lsr-algorithm so that it vectorizes AND converges by using a
270       "zebra" method: split vector loop into two with step size 2; this
271       solves a general convergence problem for the JFNK solver on a vector
272       computer. It has the potential to even improve convergence for
273       non-vector machines, but it does change the results so it is turned
274       off by default. To turn on define CPP-flags SEAICE_VECTORIZE_LSR and
275       SEAICE_VECTORIZE_LSR_ZEBRA in SEAICE_OPTIONS.h
276    
277    checkpoint64e (2013/03/05)
278    o pkg/ecco and several verification experiments:
279       Remove special versions of the_model_main.F, the_main_loop.F, forward_step.F
280       from ecco package, and revert to unified routine in model/src/
281       Adjust verification experiments accordingly, especially gloal_oce_llc90
282       Should conclude long-standing work by Gael to reconsile the_main_loop with
283       ECCO and will enable OpenAD's revolve loop in ECCO setup.
284    o pkg/generic_advdiff:
285      - implement compressible flow method for multi-dim advection (similar to
286        gad_som_advect.F); add new option "GAD_MULTIDIM_COMPRESSIBLE" (since
287        TAF generates many recomputations) to use it; no yet coded with implicit
288        vertical advection.
289      - change experiment advect_cs (new output) and advect_xy (same output)
290        to test compressible flow multi-dim advection.
291    o pkg/generic_advdiff:
292      - fix SOM advection for unusual cases (linear Free-Surf in r*, other
293        cases where linear Free-Surf is not @ k=1, e.g., useShelfIce)
294    o pkg/seaice:
295      - fix bug in the no-slip implementation in seaice_calc_strainrates.F, this
296        bug affects two verification experiments (lab_sea and lab_sea.hb87),
297        recover old (wrong) results by setting noSlipFac = 2. in
298        seaice_calc_strainrates.F;
299      - add another averaging method for etaZ (etaZmethod=3), a mix of 2 and 0
300      - add runtime parameter SEAICE_JFNKepsilon for that finite difference
301        gradient in the Jacobian times vector operation (s/r seaice_jacvec)
302      - fix line search in seaice_jfnk.F (s/r seaice_jfnk_update)
303    o pkg/seaice: reorganize seaice_lsr.F to be able to reuse more code:
304      - new subroutines seaice_lsr_tridiagu/v
305      - introduce loop bounds i/jmin/max to be able to use a restricted
306        additive Schwarz method, but not used for now.
307      - rename SEAICE_CALC_LSR_COEFFS into SEAICE_LSR_CALC_COEFFS
308      - use new subroutines seaice_lsr_tridiagu/v in s/r seaice_preconditioner
309    o OpenAD support
310       Reorganize S/R call for overall time-stepping loop to facilitate
311       OpenAD revolve loop replacement
312       (new S/R main_do_loop.F)
313    o model/src:
314      - add 3-D array 3rd dimension to argument list of S/R ADAMS_BASHFORTH2/3;
315      - pkg/cheapaml: remove local S/R ADAMS2d and use instead standard S/R
316        ADAMS_BASHFORTH2.
317    o pkg/cheapaml:
318      - add new parameter (default=F, same as before) to disable full domain
319        (including land) periodicity in X & Y dir.
320      - new S/R CHEAPAML_COPY_EDGES to copy relaxation field into edges of
321        prognostics field ; merge the 2 S/R cycle_2d_tracer and timestep_2d_tracer
322        into single S/R CHEAPAML_TIMESTEP.
323    
324    checkpoint64d (2013/02/17)
325    o pkg/monitor (angular momentum):
326      - do not add Eta contribution to the total AM if using rigid-lid;
327      - correct for Adams-Bashforth in zonal-wind part (instead of in AM_eta).
328      - horizontal discretisation: compute Zonal wind contribution separately for
329        each component (instead of from cell centered averaged) and use the 4
330        grid-cell corner averaged value of Omega*(R*cos_Phi)^2 in AM_eta part.
331      - Check that AM is conserved with linear dynamics (momAdvection=F and linear
332        FreeSurf) if using vectorInvariant momentum.
333    o model/src (horizontal grid):
334      - move initialisation of all horizontal grid arrays to null value
335        from specific horizontal grid S/R to main S/R INI_GRID;
336      - add 2 new arrays to project model C-grid velocity on to zonal direction
337        (similar to AngleCosC & -AngleSinC but at U and V point location) and
338        compute them in S/R CALC_GRID_ANGLES.
339    o pkg/seaice: replace a hard coded parameter by a runtime parameter
340        SEAICE_JFNK_tolIter
341    o pkg/seaice: introduce a restricted additive Schwarz (RAS) method in
342        preconditioner for JFNK (run LSR into the overlaps as far as possible,
343        i.e OLx/y-2, but overwrite the solution in the overlaps)
344      - extend loop range in seaice_calc_viscosity
345      - add new parameters SEAICE_OLx/y (default = OLx/y-2)
346      - add flexible loop ranges to seaice_preconditioner, seaice_calc_lsr_coeffs
347      - slightly modify loops in tridiagonal solver lsr-preconditioner
348      - by default remove the extra exchange in seaice_preconditioner with a
349        replacement of an undocumented CPP flag by SEAICE_PRECOND_EXTRA_EXCHANGE
350      - modify offline_exf_seaice so that old results without RAS are reproduced
351        for output.dyn_jfnk.txt
352      in seaice_fgmres.F (unrelated to RAS)
353      - add a cpp-flag option for a re-ordered mapping (potentially more
354        efficient), but because this changes the results, turn it off by
355        default
356      - replace the save statement by local common blocks
357    o utils/matlab:
358      - fix tile-offset in rdmnc.m when output was produced using EXCH2.
359      - update cs_grid/bk_line scripts to use load_grid.m (in utils/matlab)
360        instead of local script "load_cs.m".
361    o pkg/seaice:
362      - fix a serious bug in seaice_fgmres.F, s/r seaice_scalprod, connected
363        to the scalarProductMetric and the unrolling. By chance this does not
364        change the verification experiment, because of the particular domain
365        decomposition
366    o pkg/diagnostics:
367      - change default missing_value from UNSET_RL to -999.
368    o pkg/layers: improve vectorization of layers_fluxcalc.F
369      - step 1: split loops, make TatU/V 2D arrays. This alone reduces the cpu
370        time spent in this routine by more than a factor of 3 on an NEC-SX8
371      - step 2: replace search algorithm by a bisection algorithm found in
372        Press et al. Numerical Recipes in Fortran. This algorithm can be
373        vectorized and finds the correct bin in approx. log2(Nlayers) steps.
374        For now, use this algorithm only for TARGET_NEC_SX defined.
375      - moved the search algorithm into a separate subroutine, that is kept
376        within the same file for automatic inlining.
377      - modified catching potential errors
378    o pkg/ecco:
379      - add compile switches ALLOW_SHALLOW_ALTIMETRY and ALLOW_HIGHLAT_ALTIMETRY.
380    o model/src, pkg/autodiff, pkg/ctrl, pkg/grdchk :
381      - modifications for ALLOW_GENTIM2D_CONTROL
382      -- forward_step.F, the_main_loop.F : pass options and arrays for adjoint tapes.
383      -- load_fields_driver.F : add call to CTRL_MAP_GENTIM2D( myTime, myIter, myThid )
384      -- add xx_gentim2d0/1 in ctrl_ad_check_lev1_dir.h checkpoint_lev1_directives.h etc
385      -- use ctrl_swapffields.F (new) instead of exf_SwapFFields.F in ctrl_get_gen.F
386    o model/src:
387      - account for moist thermodynamics in (dry) potential temperature equation;
388        update results of experiments: aim.5l_cs (x2), fizhi-cs (std + aqualev)
389        and cpl_aim+ocn.
390      - also switch to standard compiler (gfortran, was using ifort previously)
391        for fizhi-cs experiments reference output.
392    o pkg/ctrl:
393      - 1st step toward generic time-varying control variable (2D) via CPP option
394        ALLOW_GENTIM2D_CONTROL
395      - note new namelist ctrl_nml_genarr in data.ctrl
396    o verification/global_ocean.cs32x15:
397      - switch off OLD_THSICE_CALL_SEQUENCE (both forward and AD code) to use new
398        thsice calling sequence and update "output.icedyn.txt" output file.
399    o pkg/ptracers:
400      - from Ryan A.: code to allow to restart a tracer at regular time interval
401        specifying a reset frequency and a reset-phase (for each tracers).
402    o pkg/thsice:
403      - implement new sequence of calls for thsice+seaice:
404          previously:   ice-Dyn,ice-Advect,ice-Thermo(thsice)
405          new sequence: ice-Thermo(thsice),ice-Dyn,ice-Advect
406      - allows (with temporary CPP option "#define OLD_THSICE_CALL_SEQUENCE"
407        in CPP_OPTIONS.h) to recover old sequence;
408      - update diagnostics for Intermediate State thsice diagnostics: now filled
409        just before advection (instead of just after advection in old sequence);
410      - update output of experiment offline_exf_seaice (standard test);
411      - in global_ocean.cs32x15 exp., postpone output.icedyn.txt update
412        by setting #define OLD_THSICE_CALL_SEQUENCE in CPP_OPTIONS.h
413    o pkg/aim_v23:
414      - use tiled array for aim_CO2 and surface wind speed for export to coupler;
415      - use standard pkg/mdsio routines to read & write CO2 pickup file;
416      - in-line S/R AIM_AIM2DYN_EXCHANGES in aim_do_physics.F;
417      - Implement new sequence of calls for seaice advection (with thsice and
418        seaice diffusion): do ice advection after ice-Thermodynamic (previously
419        was done before); change aim_do_physics.F (split the bi,bj loops block);
420      - use same CPP option (OLD_THSICE_CALL_SEQUENCE) to recover old sequence;
421    o pkg/thsice:
422      - add a missing EXCH of sIceLoad in thsice_main.F (ocean set-up) for the case
423        where just seaice diffusion is used without seaice-dynamics.
424    
425    checkpoint64c (2013/01/18)
426    o pkg/seaice:
427      - add a parameter JFNKres_tFac that can replace JFNKres_t
428        (= JFNKres_tFac*JFNKresidual before JFNK solver)
429      - add a line search option to the JFNK solver
430      - move update of u/vIce and computation of initial residual into a separate
431        routine (same file); makes the code a little easier to read (?)
432      - the line search requires computation of the residual and for some reason
433        I cannot do the update of u/vIce at the beginning of the Newton loop
434        without changing the results, so we move computation of the new residual
435        also to the end of the Newton loop, even without the line search
436    o pkg/mdsio:
437      - write missing value (corresponding to undefined array value) to meta files;
438        skip this if missing value is one (UNSET_RL would be a better value for the
439        case of undefined missing value but it's current the default missing-value);
440        Also update mdsio_read_meta.F (reading timeInterval & missing-value).
441    o pkg/exf & thsice:
442      - for diagnostics purpose, fill-up and update Qsw array (+ fill the
443        diagnostics) even when SHORTWAVE_HEATING is #undef;
444    o verification/cfc_example:
445      - turn on pkg/layers with pkg/diagnostics (to test pkg/layers and to
446        illustrate how to use it).
447    o verification/offline_exf_seaice:
448      in input: add SEAICErestoreUnderIce=.TRUE., and reduce size of forcing
449        files to only one time-record.
450      in input.thermo: narrow the 2 bands of low initial ice-concentration near
451        N & S edges; switch on SEAICErestoreUnderIce=T; use pkg/diagnostics for
452        snapshot output; same mcPheePiston value as in thsice with
453        surf-current=0.2m/s.
454      in input.thsice: similar set-up as in input.thermo (channel with same seaice
455        initial conditions).
456    o verification/cfc_example:
457      - update file "data" with more standard choice (default rotationPeriod,
458        exactConserv=T, reduce ivdc_kappa to 10, remove multiDimAdvection=F,
459        set deltaTFreeSurf to deltaTtracer) and update the output.
460    o pkg/layers:
461      - fix bolus part so that it compiles with #undef GM_BOLUS_ADVEC;
462      - ensure that "layers_bolus" is switched to False when useGMRedi=False.
463    o verification/offline_exf_seaice:
464      - set all {field}period to zero for constant-in-time forcing (not tested
465        anywhere else).
466    o verification/offline_exf_seaice:
467      - dyn_lsr  : use pkg/seaice S/R (instead of pkg/thsice) to advect sea-ice;
468      - dyn_jfnk : use pkg/thsice S/R (instead of pkg/seaice) to advect sea-ice.
469    o model/src:
470      - implement Finite-Volume method for (hydrostatic) presure gradient
471        from S.-J. Lin (QJRMS 1997), for atmosphere using sigma-coordinate.
472    o pkg/seaice: implement EVP* by Lemieux et al. (2012).
473      - In order to be compatible with the default EVP code, this requires changing
474        the EVP code around a little; and because any small change immediately
475        breaks the lab_sea.hb87 verification experiment, the reference output is
476        updated two times (each time the remaining aggrement was only 2 digits):
477        - after replacing 1/dt by 1*recip_dt with a precomputed recip_dt
478        - after replacing 1/(1+0.5*dt/tau) by a/(a+1), with a=2*tau/dt
479        The adjoint test lab_sea.evp also needed to be updated.
480      - Turn on EVP* by setting SEAICE_deltaTevp as before, and setting
481        SEAICEuseEVPstar=.true.; for EVP* SEAICE_deltaTevp does not need to be
482        a factor of SEAICE_deltaTdyn, and you can set the number of EVP steps
483        explicitly with SEAICEnEVPstarSteps (thereby overriding the default of
484        INT(SEAICE_deltaTdyn/SEAICE_deltaTevp)). Controlling EVP* is deliberately
485        kept obscure, because I need to test it a little more.
486    o pkg/cheapaml:
487      - fix few incorrect type (_RL/_RS) in subroutine calls.
488    o pkg/seaice:
489      - new S/R SEAICE_MAP_RS2VEC (similar to SEAICE_MAP2VEC) to map _RS arrays
490        to _RL vector; this fixes JFNK code when compiling with "-use_r4" option.
491    o model/src:
492      - add a warning if using select_rStar=2 with nonlinFreeSurf <> 4;
493        change (in input_ad*/data) select_rStar from 2 to 1 for AD verification
494        experiments global_ocean.cs32x15 & tutorial_tracer_adjsens (+ update output)
495    o pkg/cheapaml:
496      - replace "273.1 _d 0" by celsius2K in pkg/cheapaml/cheapaml.F and
497        update output of experiment cheapAML_box.
498      - store in CHEAPAML.h coeffs ssq[0:2] for saturation specific humidity,
499        and set them only in one place (cheapaml_readparms.F).
500      - replace "273.16 _d 0" by celsius2K & replace "3.14159 _d 0" by constant "PI"
501      - remove re-setting of main-model parameter "celsius2K" (in cheapaml_readparms)
502        and re-setting of cheapAML params "lath" & "p0" (in cheapaml_init_varia).
503    o model/src/the_main_loop.F:
504      - fix revision 129 : need both ALLOW_ECCO and ALLOW_ECCO_EVOLUTION.
505    o pkg/seaice:
506      - remove legacy branch code.
507      - retire SEAICE_GROWTH_LEGACY and SEAICE_CAP_HEFF accordingly.
508    o verification/*/code*/SEAICE_OPTIONS.h:
509      - remove documentation for retired CPP flags (SEAICE_GROWTH_LEGACY,
510        SEAICE_CAP_HEFF).
511    o pkg/cheapaml:
512      - use standard routine (S/R GET_PERIODIC_INTERVAL) to decide when it is time
513        to load new forcing fields.
514      - add missing "_d 0" where it's needed; + some editing (improve indentation).
515      - remove switch to "-r8" compiler option (no longer needed) in verification
516        cheapAML_box, keep same output (small trucation error differences).
517    o verification/offline_exf_seaice:
518      - add thermodynamics only test.
519    o verification/cheapAML_box:
520      - split the domain in 8 (2x4) tiles; add MPI and multi-threaded test;
521        keep same output (same 14 digits for cg2d).
522      - switch on "-r8" compiler option (some numerical values are missing
523        the "_d 0") and update output (only 6 digits for cg2d were preserved).
524    
525    checkpoint64b (2012/12/24)
526    o pkg/cheapaml:
527      - remove un-used variables (Qnet,EmPmR) from pickup files.
528      - store tendency of advected variables into cheapaml pickup file
529        and fix the AB-2 restart.
530    o verification/offline_exf_seaice and lab_sea adjoint:
531      - switch to new code (#undef SEAICE_GROWTH_LEGACY).
532      - switch to 4 time steps in offline, consistent with lab_sea.
533      - match parameters from SEAICE_GROWTH_LEGACY branch in data.seaice.
534      - update results after change of experiment seaice.
535    o pkg/seaice:
536      - remove option SEAICE_MULTICATEGORY; has been replaced with run-time
537        parameter SEAICE_multDim. Issue a warning if SEAICE_MULTICATEGORY is
538        still defined since SEAICE_multDim needs to be set to MULTDIM value (from
539        SEAICE_SIZE.h) to recover previous #define SEAICE_MULTICATEGORY default.
540    o model/src:
541      - add run-time parameter to select CG2D solver minimum-residual solution
542        (in case of a poor convergence).
543    o pkg/seaice/seaice_lsr.F
544      - move calculation of matrix coefficients into new
545        S/R SEAICE_CALC_LSR_COEFFS; for now this routine remains in the same
546        file; the main purpose of this change is to be able to reuse the code
547        in S/R SEAICE_PRECONDITIONER
548      - modify the computation of the residual so that the mass of sea-ice
549        is not used twice; this simplifies the calculations, but since
550        the residual is never used except when LSR_mixIniGuess.ge.4---and this is
551        not tested in testreport---this does not affect the testreport results.
552    o verification/seaice_obcs:
553      - disable SEAICE_GROWTH_LEGACY; reset input files to match those of
554        verification/lab_sea/input.salt_plume; changes results/output.txt*
555    o model/src:
556      - adapt quasi-hydrostatic formulation to work with p or p* coordinate.
557    o pkg/seaice:
558      - improve description of parameters in seaice_fgmres.F and start
559        cleaning up the code
560      - change name of SCALPROD to SEAICE_SCALPROD and modify meaning of
561        second argument
562      - add a metric based on grid cell area to SEAICE_SCALPROD; update
563        results of offline_exf_seaice.dyn_jfnk
564      - compute initial residual norm in seaice_jfnk based on SEAICE_SCALPROD
565    o pkg/aim_v23:
566      - fix an other bug in dissipation heating (grid-cell area was missing).
567    o model/src + pkg/seaice:
568      - add global (multi-tile) linear solver for pair of tri-diagonal system
569        along X and Y lines, respectively for U and V component.
570        Note: 1) MPI and cube-exchange not yet coded.
571            2) probably not accurate for poorly conditioned / large size problem.
572      - add option for SEAICE_LSR to use global (multi-tile) tri-diagonal solver;
573        default: not compiled and not used.
574    o pkg/seaice:
575      - first attempt at a multi-threaded fgmres solver for the JFNK solver:
576        introduce bi/bj loops and use global_sum_tile_rl instead of
577        mpi_allreduce in seaice_fgmres.F
578      - improve diagnostics output for fgmres solver (seaice_fgmres.F)
579      - replace a few unnecessary goto statements by if-blocks  (seaice_fgmres.F)
580      - add a verification experiment for JFNK in offline_exf_seaice
581    o verification:
582      - change (for now, only fwd test) offline_exf_seaice experiment:
583        use a re-entrant channel with idealized coastline (trapezoidal shape)
584        at southern boundary to explore seaice dynamics and thermodynamics
585        with simple forcing. Main set-up has dynamics+thermo and SST relaxation;
586        secondary test (input.thsice) use thermodynamics only with SST relaxation.
587      - add seaice-dynamics only secondary test using LSR and pkg/thsice advection.
588    o pkg/exf:
589      - disable "sstExtrapol" when Nr=1
590    o verification:
591      - add new experiment "cheapAML_box" (simple 1 layer set-up from Bruno Deremble)
592        to test pkg/cheapaml.
593    o pkg/aim_v23 & pkg/shap_filt:
594      - fix dissipation heating (erroneous gravity multiplication factor).
595    o pkg/seaice:
596      - remove unused field pressPre from jfnk solver
597      - rename two subroutines in seaice_preconditioner.F
598    o eesupp/src:
599       - S/R MDSFINDUNIT avoids reserved unit numbers (scrUnit1, eeDataUnit ...)
600    o pkg/seaice/seaice_preconditioner.F: fix preconditioner once again
601       - remove wrong parts of the rhs and the lhs (were in there
602         because I did not understand the concept of this preconditioner)
603       - add an exchange between u- and v-sweep. This increases communication
604         by a factor of two but improves the convergence of jfnk. Ideally,
605         one would like the u- and v-sweep to be independent. So far within
606         undocumented ifdefs
607       - reorganize the extra computations for printing the residuals
608    o tools/genmake2:
609      - comment out the "mpif.h" include in NetCDF test programm (for MPI built)
610        since it's not necessary (and was preventing to use MNC in some cases).
611    
612    checkpoint64a (2012/11/16)
613    o pkg/autodiff:
614      - improve pkg-internal logical parameter switch (inAd/inFwd mode) so that
615        autodiff_readparms.F no longer depends on calling order (within
616        packages_readparms.F) and no longer requires to include ${PKG}_PARMS.h):
617        rename param turnFreeDriftInAdMode to SEAICEuseFREEDRIFTswitchInAd
618        and change param SEAICEuseDYNAMICSinAdMode to SEAICEuseDYNAMICSswitchInAd.
619    o pkg/obcs:
620      - adding tidal velocity forcing capability to obcs
621        for usage example, see verification/seaice_obcs/input.tides
622    o pkg/seaice:
623      - turn the LSR-relaxation parameters WFAU/V into runtime parameters
624        SEAICE_LSRrelaxU/V
625      - introduce runtime parameter SEAICEetaZmethod (=0 by default)
626    o pkg/aim_v23:
627      - implement heating from friction (bottom friction and stratospheric drag).
628    o pkg/shap_filt:
629      - fix diagnostic "SHAP_dKE" (was 2 time smaller); implement heating from
630        dissipation but only for Shap_funct=2, active when addFrictionHeating=T.
631    o model/src:
632      - move AddMass common block from DYNVARS.h to FFIELDS.h; allow to read-in
633        time-constant addMass field from file (addMassFile);
634      - support for heating due to friction (and Kinetic Energy dissipation):
635        add option, run-time switch and 3-D field array + support code ; each pkg
636        or S/R can add heating contribution (if there is a sink of KE); the sum is
637        accounted for as a Temperature tendency term (EXTERNAL_FORCING_T).
638    o pkg/seaice:
639      - complete merge of ITD code into seaice_growth.F
640        from MITgcm_contrib/torge/itd/code/
641        no verification so far, but Torge Martin tested
642        "1-D test case and Beaufort set up;
643        deliver okay results after 1 model year."
644      - complete merge of SEAICE_SIZE.h into all relevant routines
645      - move computation of eta at Z-points into calc_viscosities
646        + introduce global field etaZ
647        + add different methods for computing etaZ, for now the old
648          method (simple averages of eta to Z-points) is hardwired
649        + replace etaMeanZ by etaZ in seaice_lsr, seaice_calc_residual,
650          seaice_preconditioner
651      - simplify computations for SEAICE_ZETA_SMOOTHREG
652      - seaice_preconditioner:
653        + replace one remaining press by pressLoc (mistake)
654        + adjust printing of residuals
655      - improve I/O of diagnostics of JFNK in seaice_jfnk.F:
656        + add (SEAICE.h) and rename some counters (initiliased in
657          seaice_init_fixed.F)
658        + add _BEGIN/END_MASTER (myThid)  around print statements
659        + print total number of iterations and failures over SEAICE_monFreq
660          interval to STDOUT
661      - move control over output-messages by fgmres to seaice_jfnk to save
662        some operations
663      - move resetting initial guess for fgmres outside of seaice_fgmres_driver
664        in order to make restarts with sol .ne. zero (fgmres with restarts)
665        (seaice_jfnk.F, seaice_fgmres.F)
666      - seaice_calc_l/rhs.F: replace maskW/S by maskInW/S; this fixes
667        a serious convergence problem when open boundaries are involved
668    o pkg/ggl90: fix computation of control volumes for the case of
669      ALLOW_GGL90_HORIZDIFF (probably not used very often): move control volumes
670      up half a grid cell from C-centered to W-centered (pointed out by C. Eden)
671    o pkg/seaice: simplify seaice_evp by avoiding use of extra fields u/vIceC
672    o pkg/autodiff
673      - Add inAdMode switch for SEAICEuseDYNAMICS:
674        SEAICEuseDYNAMICSinAdMode
675        (extend logic in ADAUTODIFF_INADMODE_SET)
676    o pkg/seaice
677      - Step 1 of merging ice-thickness distribution (ITD) code from
678        MITgcm_contrib/torge/itd/ (author: Torge Martin)
679        The code implements concept laid out in Thorndike et al. (1975);
680        code is enabled via CPP flag SEAICE_ITD
681        nITD (in SEAICE_SIZE.h) defines number of ice thickness categories;
682        code is not complete yet!!
683      - SEAICE_SIZE.h now included in almost all seaice routines
684    o verification (using seaice):
685      - switch back seaice-dynamics (+ lower SOLV_MAX_ITERS) in ADM exp.
686        global_ocean.cs32x15.seaice ; update results.
687      - compile B-grid dynamics in FW test exp 1D_ocean_ice_column ;
688      - compile C-grid dynamics with #define SEAICE_ALLOW_JFNK in FW test exp
689        offline_exf_seaice (previously compiling B-grid).
690    o pkg/exf:
691      - fix some STOP conditions in exf_check.F (from Aug 28, modifs did not allow
692        to specify neither just 1 comp of wind or wind-stress, nor no surface momentum
693        forcing): just replace CPP option ALLOW_ATM_WIND with run-time param useAtmWind.
694    o pkg/layers (adjust changes from Sept 19):
695      - do snap-shot output and fill diagnostics from inside iLa loop (layers_calc.F)
696        this allows to remove "layers_maxNum" dimension from all layers arrays.
697    o pkg/layers (adjust changes from Sept 19):
698      - remove ALLOW_LAYERS_OUTPUT ; fix snap-shot and time-ave output ;
699      - snap-shot extended to all type of layers (not just the 1rst type);
700      - remove layers variables when corresponding CPP option is undef.
701    o pkg/layers:
702      - rename pkg/layers variable and add new output (layer exist & un-weighted
703        velocity in layer)
704    o pkg/seaice:
705      - simplify (?) ocean-drag coefficent computations by using
706        the same routine in all three solvers (saves some code lines)
707      - remove global fields DRAGA and DRAGS from C-grid code and
708        declare them locally in lsr.F (the only place where they are
709        still used)
710      - update AD output of lab_sea.evp (very sensitive anyway).
711    o pkg/seaice: add Jacobian-free Newton Krylov solver for ice dynamics
712      (Lemieux et al. 2010, 2012). Turn on with the usual SEAICE_ALLOW_JFNK
713      and SEAICEuseJFNK=.true. A few things to note:
714      - involves a FGMRES, that is parallel but very inefficient,
715        because of many scalar products (global sums) in the Gram-Schmidt
716        orthogonalization method. Needs to be replaced. Original code
717        from J.-F. Lemieux
718      - preconditioner for FGMRES is a stripped down version of LSOR
719      - SOLV_MAX_ITERS is now used for LSOR as a solver and as a
720        preconditioner. For the preconditioner, the default is set to 10.
721      - Jacobian times vector is computed with finite differences
722      - marginally related to JFNK-solver: add a smooth regularization for
723        zeta with tanh that will improve convergence (Lemieux and Tremblay,
724        2009) for any implicit solver (not implemented for EVP because EVP
725        does not need this regularization in the first place). Define
726        SEAICE_ZETA_SMOOTHREG in SEAICE_OPTIONS.h to use.
727    o eesupp/src:
728      - check in genmake2 that intrinsic S/R flush is available.
729      - add S/R to flush IO unit (if intrinsic S/R flush is available)
730      - flush standard & error msg unit before MPI termination
731      - if debugMode, flush IO unit after printing msg
732    o pkg/ctrl:
733      - ctrl_unpack.F, ALLOW_GENARR3D_CONTROL code: fix missing argument in call
734        to ctrl_set_unpack_xyz.
735    
736    checkpoint64 (2012/10/09)
737    o pkg/shelfice
738      - in mom_fluxform.F, mom_vecinv.F:
739        CALL SHELFICE_V_DRAG(bi,bj,k,vFld,KE,KappaRU,vF,myThid)
740        Bug fix KappaRU -> KappaRV
741        does not change verification/isomip but may change other setups
742        (presumably constant KappaRU=KappaRV)
743      - fix diagnostics SHIU/Vdrag (thanks to Tom Millgate)
744    o pkg/obcs:
745      - fixed some indexing bugs in obcs_seaice_sponge.F
746      - added obcs relaxation subroutines for HSALT and HSNOW
747      - changes verification/seaice_obcs/results/obcs_seaice_sponge.F
748    o pkg/seaice:
749      - add "multicategory" parameterization for snow in analogy to ice,
750        default is off for now.
751    o pkg/obcs:
752      - added obcs_seaice_sponge.F for obcs relaxation of seaice variables;
753        see verification/seaice_obcs/input.seaiceSponge for example application.
754      - remove local commom bloc "OBCS_GLOBAL" in obcs_readparms.F and do all the OB
755        index setting by master-thread. This fix multi-threads Pb in previous modifs.
756    o pkg/layers :
757      - add diagnostics to pkg/layers
758      - move the meat of pkg/layers from layers_calc.F to layers_fluxcalc.F
759        (from R.Tulloch). Layers_calc.F now calls layers_fluxcalc.F accordingly.
760    o pkg/generic_advdiff/gad_implicit_r.F :
761      - fix ADVr diagnostics in case of both implicit vertical advection and diffusion.
762    o pkg/seaice/seaice_growth.F:
763      - fix SItflux diagnostics in virtual salt flux + balanceEmpmr case.
764    o pkg/obcs:
765      - change default setting of OBCS_UVICE_OLD from defined to undef;
766      - use new parameter OB_indexNone for null index value (instead of hard-coded 0)
767        in all pkg/obcs code and in other pkgs; remove k loop in obcs_check_depths.F;
768      - pass OB_indexNone as (new) argument to S/R CTRL_MASK_SET_[X,Y]Z;
769      - change OB null index value (OB_indexNone) to -99 ; this fix the problem
770        with Southern & Western OB at a tile edge (at least in a simple set-up).
771    o pkg/obcs:
772      - change settings of OB index in case OB coincides with tile edge (shared by
773        2 tiles), so that common OB location is registered by both tiles (instead of
774        only 1). However, for Southern and Western OB, index value = 0 is not
775        recognized as valid OB index (=default null value) and needs to be fixed.
776      - modify accordingly OBCS_BALANCE_FLOW and OBCS_MONITOR (avoid double counting)
777      - new parameter "OB_indexNone" for null index value (for now, still zero)
778        to replace hard-coded null index value of zero.
779    o pkg/exch2:
780      - improve W2_USE_E2_SAFEMODE (faster) and W2_E2_DEBUG_ON:
781        always check buffer-size (but outside the loop); move checking for valid
782        index from W2_USE_E2_SAFEMODE to W2_E2_DEBUG_ON; in W2_E2_DEBUG_ON,
783        print each tile and point connection only if |W2_printMsg|>= 2 and 3.
784    o pkg/ctrl (pack & unpack):
785      - in ctrl_pack.F & ctrl_unpack.F, use the same local file-name variable
786        (locally defined) for different variables (+ remove the variable-specific
787        file name in CTRL_GENARR.h). For now, only implemented for GENARR2/3D_CONTROL
788        (to be extended to other local file names in ctrl.h).
789    o pkg/flt:
790      - add a FLT_Iter0 option (similar to PTRACERS_Iter0).
791    o pkg/mdsio:
792      - fix missing STOP in mdsio_readvec_loc.F (case ioUnit=0) when file is missing
793    o tools/genmake2:
794      - add similar dependences for target EXE_AD & EXE_FTL as we have for EXECUTABLE
795        (added by Alistair in version 1.51 for building without make depend);
796      - remove Header files list (H_SRC_FILES) from the dependence of targets
797         ad_input_code.f & ftl_input_code.f (not clear why it was added in the first
798        place in version 1.23): this save going through staf when unrelated header
799        file has been modified.
800       Note: for an intermediate target (e.g., ad_input_code.f or adtaf) without
801        "make depend" step, still need to do "make links" before "make adtaf".
802    o eesupp/src (+ few pkg src files) & genmake2:
803      - finish to remove ALWAYS_USE_MPI in source code that TAF does not see;
804      - no longer set ALWAYS_USE_MPI in Makefile (was done by genmake2).
805      - improve genmake2 checking for ALLOW_${PKG} in CPP_OPTIONS.h files (distinguish
806         upper/lower case ; account for space between "#" and undef/define)
807    o pkg/flt (with exch2):
808      - cleaning: fix so that it compiles; move remaining MPI calls out of flt_exch2.F;
809      - simplify threads synchronisation; fix (many issues) multi-threaded with MPI.
810    
811    checkpoint63s (2012/09/05)
812    o pkg/ecco:
813      - remove #ifdef ALLOW_SMOOTH_CORREL3D brackets.
814      - add more relevant #ifdef ALLOW_SMOOTH ones.
815      - sort out useAtmWind, useSMOOTH, ctrlSmoothCorrel2D.
816    o pkg/ctrl:
817      - CTRL_OPTIONS.h : document CPPs related to smoothing; ALLOW_SMOOTH_CORREL2D/3D,
818        ALLOW_CTRL_SMOOTH, ALLOW_SMOOTH_CTRL2D, ALLOW_SMOOTH_CTRL3D.
819      - ctrl.h : document run time params doInitXX, doMainPack, doMainUnpack, doPackDiag,
820        doSinglePrecTapelev (audodiff param!), ctrlSmoothCorrel2D (new) and
821        ctrlSmoothCorrel3D (new).
822        The added ctrlSmoothCorrel2D/3D replace the old ALLOW_SMOOTH_CORREL2D/3D CPP.
823      - ctrl_readparms.F : initialise ctrlSmoothCorrel2D/3D and read from namelist.
824      - ctrl_init.F ctrl_pack.F ctrl_unpack.F : switch off ustress/vstress
825        controls when useAtmWind, and vice versa.
826      - ctrl_map_ini_ecco.F : UVEL0, VVEL0, edtaux, edtauy cannot be smoothed as tracers.
827      - ctrl_get_gen.F : replace #ifdef ALLOW_SMOOTH_CORREL2D with
828          #ifdef ALLOW_SMOOTH, IF ctrlSmoothCorrel2D, IF useSMOOTH.
829      - ctrl_map_ini_gen.F : replace #ifdef ALLOW_SMOOTH_CORREL3D with
830          #ifdef ALLOW_SMOOTH, IF ctrlSmoothCorrel3D, IF useSMOOTH.
831      - ctrl_set_pack_xy[z].F, ctrl_set_unpack_xy[z].F:
832        replace ALLOW_SMOOTH_CORREL2D/3D brackets with ctrlSmoothCorrel2D/3D.
833    o pkg/smooth:
834      - remove un-necessary includes.
835      - remove ALLOW_SMOOTH*D and ALLOW_SMOOTH_CORREL*D brakets.
836        Those CPP options were never defined, and not necessary.
837    o model/src:
838      - fix CPP brackets in ini_mixing.F (GM_background_K belongs to gmredi).
839      - standard treatment of useSMOOTH.
840    o pkg/autodiff:
841      - add LOGICAL useGGL90inAdMode, useGGL90inFwdMode, useSALT_PLUMEinAdMode,
842        useSALT_PLUMEInFwdMode allowing to switch off ggl90 and salt_plume adjoint.
843    o pkg/exch2:
844      - add "if usingMPI" where it was missing (in exch2_rx?_cube*.template)
845        + start to remove ALWAYS_USE_MPI in source code that TAF does not see.
846      - make new S/R W2_MAP_PROCS out of w2_eeboot.F to setup exch2 CommonFlag
847        and tiles to process mapping.
848      - re-arrange 3 header files (W2_EXCH2_PARAMS.h, _BUFFER.h & _TOPOLOGY.h)
849        moving /EXCH2_FILLVAL_RX/ & /W2_EXCH2_COMMFLAG/ to W2_EXCH2_TOPOLOGY.h;
850        rename "exch2_tProc" to "W2_tileProc" and move seting of e2FillValue_RX
851        from w2_eeboot.F to w2_readparms.F.
852    o eesupp/src:
853      - set exchNeedsMemsync & exchUsesBarrier according to "usingMPI" (instead of
854        ALWAYS_USE_MPI) + moved from ini_communication_patterns.F to eeset_parms.F;
855        also move setting of exchCollectStatistics from exch_init.F to eeset_parms.F
856      - in eedie.F and all_proc_die.F, always call MPI_FINALIZE when ALLOW_USE_MPI
857        is defined (remove condition on usingMPI) to match cases where MPI_INIT
858        has been called.
859      - fix bug I put in previous modif of exch_sm_3d_rx.template (not much used);
860      - change default (non-MPI) value of myPid (from 1 to 0) to match MPI settings
861        (so that on 1 proc, get same myPid independently of usingMPI)
862      - add a stop if multi-procs but usingMPI=F ; stop also if usingMPI=T and
863        useCubedSphereExchange with EXCH-1 (safer).
864      - add "if usingMPI" where it was missing (+ start to remove ALWAYS_USE_MPI).
865    o pkg/ggl90:
866      - fix bug in filling corner mask array "mskCor" (FILL_CS_CORNER_TR_RL call)
867        used in ALLOW_GGL90_SMOOTH code.
868    o pkg/flt:
869      - fix typo in FLT_WITHOUT_Y_PERIODICITY (the effect was to ignore stopping
870        floats at the Southern end of the domain).
871    o eesupp/inc:
872      - add a list of CPP-options which can be set by Makefile (DEF_IN_MAKEFILE.h);
873        but not used (and not to be used) anywhere, just for documentation.
874    o pkg/autodiff, exf, ptracers & seaice (AD & TL output):
875      - comment out the very nasty "writeBinaryPrec = writeStatePrec" line, since:
876        a) can damage previously written records in any other multi-record files.
877        b) if needed, can easily do it cleanly, by calling S/R WRITE_REC_3D_RL/S.
878    o tools/genmake2:
879      - define variable MAKE within Makefile and use it in place of 'make';
880      - update AD_CONFIG.h (if needed) before building any of the executable
881        (forward, adjoint or tangent-lin); this involves a 2nd invocation of make;
882        and add the usual #ifndef/#define AD_CONFIG_H in AD_CONFIG.h;
883      - always print usual warning comment 'this file is automatically generated'
884        from script convert_cpp_cmd2defines (+ remove this warning from genmake2).
885    o pkg/cheapaml:
886      - updated to correspond to the code used in accepted paper (Nico Wienders).
887    o pkg/exf:
888        added run time switch useAtmWind to replace ALLOW_ATM_WIND cpp switch.
889        ALLOW_ATM_WIND now just sets the useAtmWind default (see exf_readparms.F)
890        and force defines ALLOW_BULKFORMULAE (EXF_OPTIONS.h).
891    o pkg/exf, autodiff, ctrl, ecco and seaice:
892        remove ALLOW_ATM_WIND brackets, or replace them with useAtmWind ones.
893    o pkg/ctrl, ecco:
894        allow to compile both ALLOW_U/VSTRESS_CONTROL and ALLOW_U/VWIND_CONTROL.
895        Depending on useAtmWind, one is inactive, and the other is active (see
896        exf_getffields.F/exf_getsurfacefluxes.F).
897    o tools/genmake2:
898      - improve error msg when failing in 2nd test of check_for_broken_Ff
899      - fix option '-makefile' short-name (-mf according to genmake2 -help)
900      - source local config file "genmake_local" just after processing the genmake2
901        command arguments (previously done before processing arg).
902    o pkg/grdchk:
903      - add a call to TURNOFF_MODEL_IO for Tangent-Linear run (in this case, call
904        to this routine from cost_final has been dropped in g_cost_final)
905      - improve printed information (more explicit msg, no longer using "print *,"
906         fix fcpertminus printed value).
907    o model/src:
908      - move call to COST_INIT_VARIA out of packages_init_variables.F directly
909        into initialise_varia.F (just after calling PACKAGES_INIT_VARIABLES):
910        this prevents getting cost-funct reset in adinitialise_varia recomputations.
911    o pkg/dic:
912      - move initialisation of "freefe" array from from dic_biotic_forcing.F to
913        fe_chem.F: this prevents TAF from dropping this initialisation in TLM code.
914    o pkg/grdchk:
915      - grdchk_main.F : added CALL GLOBAL_SUM_INT( ierr , myThid )
916      - grdchk_getadxx.F etc. : omit I/O if ierr.EQ.0
917    o pkg/autodiff/ctrl/grdchk :
918      - attempt to sort out what works and what does not,
919        with regard to I/O, and to warn/stop accordingly.
920    o pkg/grdchk:
921      - attempt to fix grdchk in the case of useSingleCpuIO.
922      - "if ( myProcId .EQ. grdchkwhichproc .AND. ierr .EQ. 0 )"
923       statements were moved from grdchk_main.F and into
924       grdchk_getadxx.F grdchk_getxx.F grdchk_setxx.F.
925      - a global sum is applied to record numbers icvrec/layer
926       out of grdchk_loc so that they be passed to I/O routines.
927    o pkg/smooth:
928      - fix recomputation that appeared with nlfs : use smooth_recip_hFacC,
929        smooth_hFacW, smooth_hFacS (copied at init_fixed) in 3d case.
930    o verification/testreport:
931      - add option '-tlm' for Tangent-Linear test (-adm,-oad,-tlm are all exclusive);
932      - can also use compressed (gzip) reference output file;
933      - change format (in pkg/grdchk) of TLM output (+ add forward gradient)
934        to be easier to collect by testreport.
935      - update existing TLM output (half out-of-date by more than 3 yrs).
936      - report NETCDF & LAPACK settings (from genmake2) in output dir.
937      - report run-time in each individual summary (previously only for AD test);
938        for TLM test, add also TAF version.
939      - add daily TLM test on (old) aces cluster + weekly test on baudelaire.
940    
941    checkpoint63r (2012/08/15)
942    o tools/genmake2:
943      - fix Makefile for target ftlall (+ update files to clean after make ftlall)
944    o pkg/ecco/ecco_cost_final.F :
945      - fix fc print statements (to stdout and costfunction0000) so
946        that the printed value is always after the global sum.
947    o pkg/seaice/seaice_dynsolver.F :
948      - fix ice strength assymptote at SEAICE_area_max<1
949        (no change for the standard case of SEAICE_area_max=1)
950    o some cleaning:
951      - pkg source files: ensure that all *.F files from each pkg included the
952        corresponding ${PKG}_OPTIONS.h file (except stand-alone src file which
953        only includes CPP_EEOPTIONS.h); fix S/R CTRL_SMOOTH ; update AD experiment
954        code_ad/*.F src files; add new option-file in pkg/admtlm + corresponding
955        includes;
956      - model/src: add PACKAGES_CONFIG.h wherever ALLOW_AUTODIFF[_TAMC] is used.
957      - ALLOW_DIFFKR_CONTROL: add a stop in S/R CTRL_CHECK in case ALLOW_3D_DIFFKR
958        is undef; also define /DYNVARS_DIFFKR/ common block in DYNVARS.h when
959        ALLOW_DIFFKR_CONTROL is defined, to allow to compile and reach this stop.
960      - update option-file CPP_OPTIONS.h of all AD experiments:
961        * no longer include PACKAGES_CONFIG.h ;
962        * includes ECCO_CPPOPTIONS.h if PACKAGES_CONFIG.h has been included ;
963        * def/undef ALLOW_3D_DIFFKR independently of ALLOW_DIFFKR_CONTROL (before
964          including ECCO_CPPOPTIONS.h).
965    o pkg/cost, pkg/ctrl, pkg/ecco option-file:
966      - clean-up and split content of old pkg/ecco/ECCO_CPPOPTIONS.h file into
967        separated pkg option-file (done according to old doc from ECCO_CPPOPTIONS.h,
968        not necessary accurate).
969      - add a template for option-file ECCO_CPPOPTIONS.h, mostly empty, in
970        pkg/autodiff, i.e., the 1rst pkg to compile for adjoint built, with lines to
971        deliberately break compilation (a remainder that it needs to be customized)
972      - in pkg/ecco, includes ECCO_OPTIONS.h instead of COST_OPTIONS.h
973      - rename COST_CPPOPTIONS.h to COST_OPTIONS.h
974      - rename CTRL_CPPOPTIONS.h to CTRL_OPTIONS.h
975    o tools/genamke2:
976      - check for lapack.
977    o pkg/cost and pkg/ecco : attempt to sort out some of the limiting intricacies.
978      - pkg/cost.cost_final.F : allow for use of pkg/ecco and pkg/cost cost functions
979        jointly. The exclusive ifdefs were removed, to add costs terms (when defined)
980        from both packages.
981      - the fc global sum in pkg/ecco/ecco_cost_final.F was removed accordingly.
982      - for objf_atl we use either the pkg/ecco or the pkg/cost term depending on CPPs.
983      - pkg/ecco and model/src : add CPP brackets around pkg/cost and pkg/ctrl includes
984        of "CTRL_SIZE.h" "ctrl.h" "ctrl_dummy.h" "optim.h" / "cost.h" accordingly.
985    o pkg/cost : add comments to explain special and/or untested setups.
986    o pkg/exf:
987      - use EXF_OPTIONS.h to set pkg/exf options except if done in ECCO_CPPOPTIONS.h
988        (previously, ALLOW_AUTODIFF_TAMC was controling this switch).
989    o verification/*/code_ad:
990      mimimal cleaning of AD experiments ECCO_CPPOPTIONS.h option-file:
991      - reccord when this file is included (define ECCO_CPPOPTIONS_H)
992      - remove the most obvious obsolete features (e.g., #define ALLOW_COST not
993        allowed since Oct 2003 in any option-file except in PACKAGES_CONFIG.h)
994    o pkg/seaice :
995      - added possibility to change ice strength/PRESS0 relationship to
996        HEFF, according to the following run time parameters
997        SEAICEpresPow0 :: HEFF exponent for ice strength below SEAICEpresH0 (integer, >0)
998        SEAICEpresPow1 :: HEFF exponent for ice strength above SEAICEpresH0 (integer, >0)
999        SEAICEpresH0   :: HEFF threshold for ice strength            (m)
1000    o pkg/ggl90 :
1001      - added run time flag mxlSurfFlag to include the code that ensure
1002        mixing between first and second level (previously included as a comment)
1003    o verification/1D_ocean_ice_column/input_ad/data.autodiff :
1004      - add test of newly added dumpAdByRec=T option where
1005        we write all records to one file per variable.
1006    o verification/global_ocean.cs32x15/code_ad/CPP_OPTIONS.h :
1007      - switch to #define ALLOW_BALANCE_RELAX and ALLOW_BALANCE_FLUXES
1008        to check that this code is ok with taf and compiles in adjoint.
1009    o pkg/autodiff :
1010      - added run time param dumpAdByRec : ad dump format switch.
1011        If true then write all records to one file per variable.
1012        Else write one file per record (remains the default).
1013      - revise seaice_ad_dump.F and exf_adjoint_snapshots_ad.F accordingly.
1014    o pkg/seaice:
1015     - Added SEAICEuseTILT run time switch : if set to
1016       false then omit the tilt term in seaice dynamics.
1017     - Fix free drift calculation.
1018    o pkg/shelfice:
1019      When initializing SHELFICEDragQuadratic, set default to be
1020      consistent with shiCdrag in case SHELFICEuseGammaFrict is used,
1021      but retain option to set it independently
1022      (inconsistenty spotted by Veronique Dansereau)
1023    o eesupp/inc:
1024      - in EEPARAMS.h, add real-type constant for some frequently used simple number
1025         (0,1,2,1/2), with name explicitly referring to RS/RL type.
1026    o model/src:
1027      - move balancing of relaxation terms to new S/R balance_relax.F.
1028    o pkg/autodiff:
1029      re-write active I/O high-level (control) S/R:
1030      - rename  S/R ACTIVE_READ/WRITE_RL to ACTIVE_READ/WRITE_3D_RL
1031      - add 1 more argument (useCurrentDir) to replace the "_LOC" 2nd set of S/R.
1032      - use standard pkg/mdsio I/O routines (MDS_READ/WRITE_SEC_XZ/YZ  and
1033        MDS_READ/WRITE_FIELD); change loops to multi-threads.
1034      - update and merge active_file_control_slice.flow into active_file_control.flow
1035      - update the calls in lower level S/R (active_file.F, active_file_g.F and
1036        active_file_ad.F) keeping the argument list and function unchanged.
1037      - also update lower-level "_LOC" version (call same S/R with "useCurrentDir
1038        =.TRUE.") and remove high-level (control) _loc version (not called anymore).
1039      - new low-level active I/O routines, one for each type (RL/RS), for active var
1040        of various (XY,XZ,YZ) shape and level number (arguments: arrShape, myNr);
1041        fix ctrl_init_wet.F & ecco_cost_weights.F by calling the new S/R with the
1042        right type.
1043    o autodiff and RS=real*4:
1044      - call the right type (_RS instead of _RL) of S/R in few output S/R (pkg/exf
1045        ad-monitor and snapshots); disable arrType='RS' in mdsio_gl*.F ;
1046      - change argument type of 3-D mask argument to _RS to match type in the call
1047        (in seaice_cost*.F, ctrl_*_gen.F and *ctrl_bound.F); to be continued.
1048    o pkg/thsice:
1049      - re-anable balanceEmPmR when useSEAICE=T with useThSIce=T.
1050      - option to correct ocean fresh-water flux for imbalance of Atmos+Land
1051        fresh-water flux: uniform correction or proportional to local precip.
1052    o pkg/ctrl:
1053      - new header file CTRL_SIZE.h for parameters maxCtrlArr2D, maxCtrlArr3D
1054      - redefine CPP option ALLOW_BOTTOMDRAG_CONTROL to
1055                            ALLOW_BOTTOMDRAG_CONTROL_NONGENERIC
1056      - verification/hs94.1x64x5/ tests ALLOW_GENARR{2D,3D}_CONTROL
1057    
1058    checkpoint63q (2012/07/30)
1059    o pkg/autodiff:
1060      note about monitor and snap-shot of ad-variables:
1061      a) need to apply ADEXCH before monitor or output of ad-vars to include
1062       overlap contributions (was done for adjDump but missing for monitor).
1063      b) since ADEXCH implies adding overlap values to interior array, machine
1064       truncation error is expected when adding an ADEXCH call in the middle of
1065       the time-stepping (although mathematically identical).
1066      modifs:
1067      - fix some incorrect type (RL/RS, UV/scalar) in ADEXCH calls and ad-vars
1068        declaration (adEddyPsiX,adEddyPsiY in adcommon.h).
1069      - add new run-time params (dumpAdVarExch & mon_AdVarExch) to select how  to
1070        apply ADEXCH before monitor or snap-shot of ad-variables:
1071           =0 : no ADEXCH ; =1 : do ADEXCH ; =2 : apply ADEXCH on a local copy.
1072      - implement new method (copy+adexch) for snap-shot and monitor of main model
1073        ad-vars (initially not used by default -> output unchanged).
1074      - change default (set to 2) to use new method and update few output_adm.txt
1075        with accurate ad-monitor (global_ocean.90x40x15, tutorial_global_oce_biogeo
1076        and both tutorial_tracer_adjsens tests).
1077      - switch 2 global_ocean.cs32x15 AD-tests to AB-2 (seaice_dynmix & thsice)
1078        and turn off momDissip_In_AB in the 2 other (needed for stable AB-3).
1079    o pkg/ctrl:
1080      enable the use of a variable number (maxCtrlArr2D, maxCtrlArr3D) of
1081      generic control variables via
1082      #define ALLOW_GENARR2D_CONTROL and/or #define ALLOW_GENARR3D_CONTROL
1083      Only required customization should be S/R ctrl_map_ini_genarr.F
1084      (routine in repository contains example)
1085    o pkg/exf:
1086      - fix and refine checking of surface-relaxation setting when using EXF
1087    o verification (adjoint exp):
1088      - reduce length of simulation by half for experiment global_ocean.cs32x15
1089        (std, seaice & seaice_dynmix) and exp tutorial_dic_adjoffline; update output.
1090    o pkg/mom_common (mom_u/v_bottomdrag), pkg/shelfice (shelfice_u/v_drag)
1091      - replace if statements KE.ne.0 with KE.gt.0 to avoid sqrt of negative numbers
1092        of KE that can occur with aggressive optimization
1093      + put quadratic bottom drag calculation in separated loops (only done if
1094        using bottomDragQuadratic)
1095    o model/src: CG2D_NSA
1096      - clean-up:  stop if cg2dNormaliseRHS=T and AUTODIFF
1097         and replace GLOBAL_SUM calls with GLOBAL_SUM_TILE.
1098      - in test-exp that uses CG2D_NSA (bottom_ctrl & tutorial_tracer_adjsens),
1099         change cg2d residual target to be expressed in Wunits (=> do not normalise
1100         RHS ; this fix global_max Pb with TAF); update output.
1101    o verification/tutorial_tracer_adjsens:
1102       improve parameter consistency (and get rid of warnings):
1103       - use deltaTFreeSurf=deltaTtracer (better with NonLin FreeSurf);
1104       - switch Temp Adv Scheme from 81 to 80 (no limiter since theta < 0 is physical)
1105       - use staggerTimeStep (for stability) in som81; use default rotation period.
1106    o pkg/exch2:
1107      - with empty facet: fix compact-format (W2_mapIO=1) definition (was previously
1108        reset to 0 = 1 long line in X)
1109    o pkg/mdsio:
1110      - fix reading of dimensions from meta file for large-size domain
1111    o model/src:
1112      - fix saltIsActiveTr setting for IdealGas eosType (eosType is 6 character long);
1113      - to refine CS-grid check, add logical flag "hasWetCSCorners": true if using
1114        Cubed-Sphere Exch with CS-corners inside the domain;
1115        make new S/R INI_GLOBAL_DOMAIN from code in ini_linear_phisurf.F to calculate
1116        globalArea and to set hasWetCSCorners.
1117      - add warning if usingCurvilinearGrid and momAdvection in flux-form (missing
1118        metric terms); stop if hasWetCSCorners=T and momAdvection in flux-form.
1119      - re-activate the stop if useCDscheme and hasWetCSCorners=T (previously if
1120        useCDscheme and useCubedSphereExchange).
1121    o pkg/seaice/seaice_growth.F :
1122      - compute the SEAICE_DISABLE_HEATCONSFIX term accordingly
1123        for the (.NOT.useRealFreshWaterFlux).OR.(nonlinFreeSurf.EQ.0)
1124        when the previous code was not correct.
1125      - in all cases diagnoze the boundary condition mismatch to SIaaflux
1126      - in the case of useRealFreshWaterFlux.AND.(nonlinFreeSurf.GT.0) add
1127        that term to QNET (essentially to set the melt/freeze water to 0degC).
1128        when SEAICEheatConsFix is true, so that the ocean+ice budget heat is closed.
1129    o verification/global_ocean.cs32x15/input.seaice :
1130      - add SEAICEheatConsFix in data.seaice, ensuring closed ocean+ice heat budget.
1131      - add diagnostics (commented out) for budget test using my matlab codes (gcmfaces).
1132      - update results (output.seaice.txt) accordingly.
1133    o verification/lab_sea/input/data.seaice :
1134      - remove SEAICEheatConsFix, which is now be tested
1135        in global_ocean.cs32x15. The presently coded fix
1136        is only consistent with real fresh water + nlfs.
1137      - update results (output.txt) accordingly.
1138    o pkg/salt_plume: added diagnotic for salt tendency (oceSPtnd).
1139    o AD_CONFIG.h file:
1140      - in genmake2: remove "#undef ALLOW_ECCO_OPTIMIZATION" from AD_CONFIG.h;
1141      - remove #include "AD_CONFIG.h" from all included OPTIONS files and
1142        add it explicitly in each fortran src file where it is needed.
1143        motivation: header file AD_CONFIG.h is generated/modified after "make depend"
1144        thus introducing potentially wrong dependency; therefore, better to include
1145        it only where it's really needed, and after any other included OPTIONS file
1146        (less tempting to bring conditional includes according to ALLOW_ADJOINT_RUN
1147        or ALLOW_TANGENTLINEAR_RUN).
1148    
1149    checkpoint63p (2012/07/06)
1150    o pkg/autodiff:
1151      - rename S/R INI_AUTODIFF to AUTODIFF_INIT_VARIA ;
1152      - create new header file "AUTODIFF_PARAMS.h" for pkg/autodiff parameters
1153        which are now read from new parameter file "data.autodiff" (inAdExact
1154        previously in "data", use{KPP/GMRedi/SEAICE}inAdMode previously in data.pkg)
1155      - add file "data.autodiff" in all verification/*/input_ad/ directories.
1156      - add run-time parameter to turn On/Off SEAICEuseFREEDRIFT in adjoint/forward
1157        mode (used in global_ocean.cs32x15.seaice_dynmix test exp.)
1158    o verification/tutorial_tracer_adjsens/
1159      - add extra sub-verification which uses "SOM" advection scheme
1160        (2nd Order-Moment Advection Scheme, Prather Limiter) with
1161          #define GAD_ALLOW_TS_SOM_ADV in GAD_OPTIONS.h
1162        and in data:
1163          multiDimAdvection=.TRUE.,
1164          tempAdvScheme=81,
1165          saltAdvScheme=81,
1166    o model/src:
1167      - introduce ALLOW_BALANCE_RELAX which allow the removal
1168       of the global mean of relaxation terms by setting
1169       balanceThetaClimRelax and balanceSaltClimRelax
1170      - disable balanceEmPmR and balanceQnet in the case when useSeaice.
1171       This case is now treated appropriately in seaice_growth.F
1172    o pkg/seaice:
1173      - do balanceEmPmR and balanceQnet based on the net fluxes
1174        (SItflux) that enter the ocean+ice system rather than QNET
1175        and EMPMR. Works best in real fresh water.
1176      - SIatmFW, SIatmQnet, and SItflux computations had to be moved
1177        out of the diagnotics bloc, and stored in global arrays.
1178    
1179    checkpoint63o (2012/06/29)
1180    o vertical mixing schemes:
1181      - remove unused S/R CALC_BUOYANCY (left from branch-atmos merging)
1182      - replace computation of density (in Function STATE1, opps_calc.F) by a call
1183        to S/R FIND_RHO_SCALAR
1184      - pass sigmaR to S/R PP81_CALC, MY82_CALC (but not yet used) and to GGL90_CALC
1185        and use it for N^2 calculation in ggl90_calc.F (save 2 density computations);
1186        affects output (vermix.ggl90) at truncation level.
1187    o testreport:
1188      - change adjustment of SIZE.h for mpi+mth testing: preserve enough tiles
1189        (nSx,nSy) for the number of threads (from eedata.mth)
1190    o model/src:
1191      - remove 2nd set of calls at the top of initialise_varia.F (Adjoint part)
1192        related to Non_Lin Free-Surf or Bottom-Control (but not longer necessary).
1193    o verification/tutorial_tracer_adjsens/
1194      - compile with ALLOW_CG2D_NSA
1195      - run with nonlinFreeSurf=3
1196      - update reference output_adm.txt
1197    o tools/genmake2:
1198      - add "-DHAVE_NETCDF" to the DEFINES list when NetCDF is available ;
1199        refine usePROFILES switching off (only when NetCDF is not available).
1200    o verification (atmospheric set-up):
1201      - change eosType='IDEALGAS' to eosType='IDEALG' to match variable declaration
1202    o pkg/profiles : refine profiles and files handling.
1203    o model/src and pkg/ecco : introduce run-time switch usePROFILES.
1204    o model/src/the_main_loop.F, forward_step.F and pkg/exf/EXF_OPTIONS.h :
1205      - changes to use model/src/the_main_loop.F rather than the ecco version
1206        in ecco type adjoint runs.
1207    o model/src:
1208      - move computation of recip of grid distance & area from INI_MASKS_ETC to INI_GRID
1209      - move setting of h0Fac[C,W,S] from INI_LINEAR_PHISURF to INI_MASKS_ETC
1210      - update_masks_etc.F: rename SMOOTH*_R4,R8 function to the corresponding type (RS,RL)
1211    o model/src:
1212      - fix S/R UPDATE_CG2D for ALLOW_DEPTH_CONTROL case (was empty before);
1213        update output of test experiment bottom_ctrl_5x5.
1214    o pkg/generic_advdiff:
1215      - implement vertical bi-harmonic diffusion (for now, only for T & S and
1216        only explicitly).
1217    o verification/bottom_ctrl_5x5/
1218      update reference output (results changed quite some time ago,
1219      not sure when; but new reference results look ok in terms of grdchk)
1220    o verification/1D_ocean_ice_column/
1221      For verification purposes, the exact adjoint rather than an approx.
1222      should be used (e.g., to comare against F.D. or TLM).
1223      removed autodiff_inadmode*_ad.F routines in code_ad/
1224      Update results/ accordingly.
1225    o pkg/cal:
1226      - change cal_getdate.F so that output date is function of input time only
1227        (less ambiguous, not mixed up with input iteration number).
1228      - fix calendarDumps for non-zero phase-lag (S/R CAL_TIME2DUMP).
1229    o pkg/diagnostics:
1230      - implement calendarDumps also for stats-diags
1231      - implement calendarDumps also for snap-shot output (negative freq)
1232      - for now, ignores calendarDumps if non-zero phase-lag.
1233    
1234    checkpoint63n (2012/06/04)
1235    o model/src:
1236      - recompute rSurfW & S to ensure consistent column thickness (needed for rStar)
1237        between Sum_k(hFac*drF) and rSurf-rLow, for now only when using pkg/shelfice;
1238      - use h0FacC, W & S to compute hFac_surfC, W & S in calc_surf_dr.F (more
1239        similar to calc_r_star.F); update results of experiment internal_wave and
1240        tutorial_global_oce_in_p (affected @ truncation level).
1241    o pkg/shelfice:
1242      - add parameterisation of advective-diffusive flux into the ice shelf
1243        according to Holland and Jenkins (1999), eq.22-33, as suggested by Jan De Ryd
1244      - simply eps3/3a computation
1245    o eesupp:
1246     - add new CPP option (DISCONNECTED_TILES) to disconnect tiles (no exchange
1247       between tiles, just fill-in edges assuming locally periodic subdomain) and
1248       add corresponding exchange subroutines (EXCH0);
1249     - new CG-solver version (_EX0) for disconnected-tiles special case.
1250    o model/src (CG-solvers):
1251     - modify Single-Reduction version (CG2D_SR) in case cg2dMaxIters is reached
1252       (similar final residual output and max-Iter number as with standard version);
1253     - allows to store and use lowest-residual solution (standard & _SR versions);
1254     - cleaning up (remove old, commented out code, LETS_MAKE_JAM ...).
1255     - by default, also compile CG2D_SR version (define ALLOW_SRCG in CPP_OPTIONS.h)
1256    o eesup/src:
1257     - global_vec_sum.F cleaning: add a BARRIER ; update comments ; remove ndef
1258       ALWAYS_USE_MPI (no longer needed after fixing usingMPI settings - March 2012)
1259    o pkg/salt_plume added to lab_sea/input_ad.noseaicedyn
1260    
1261    checkpoint63m (2012/04/27)
1262    o pkg/shelfice:
1263     - account for partical cells in surface level below ice-shelf for hydrostatic
1264       pressure calculion (set uniformFreeSurfLev to F); update isomip experiments.
1265    o ad test experiments:
1266     - update and rename to "ad_optfile.local" local AD-optfile specific to a
1267       particular adjoint verification experiment (in verification/*/code_ad/)
1268    o pkg/seaice & pkg/exf:
1269     - Part two of ECCO-CLIVAR code merges.
1270       Completes merge of seaice area relax. code.
1271       Requires unified CPP option EXF_ALLOW_SEAICE_RELAX
1272       to be set in EXF_OPTIONS.h since this pkg controls its I/O
1273       (and avoids second CPP option in SEAICE_OPTIONS.h)
1274     - change default value of costIceStart & costIceEnd to a valid date.
1275     - add snowPrecip to HSNOW in seaice_growth
1276    o pkg/ptracers:
1277     - move ptracers summary and setup check into separated S/R ; add a check for
1278       valid PTRACERS_Iter0 value (error+stop or just warning).
1279    o pkg/cal (+ pkg/ecco):
1280     - avoid calling a S/R with 2 times the same arg (FWD: unless both are only used
1281       as input; and for AD, unless both are not differentiable (e.g., k index)).
1282    o model/src:
1283     - define internal flag "uniformFreeSurfLev" (=T when free-surface level-index
1284       is everywhere k=1) to speed-up some calculations (by pass kSurf reference);
1285       temporary set to usingZCoords value (to be changed to F when using shelfice).
1286     - hydrostatic pressure: implement partial cell near the surface also for
1287       Z-coordinates (for the case where uniformFreeSurfLev=F); replace test on
1288       usingZCoords with test on uniformFreeSurfLev where needed (in NonHyd code).
1289    o pkg/ctrl/ctrl_init.F:
1290     - add a formal parameter to s/r ctrl_init_rec to print
1291       xx_$(ctrl_valiable)_file for easier debugging
1292     - move call of cal_* routines into the if-block where they are really
1293       needed so that xx_$(ctrl_variable)_period can be 0 or -12 without having
1294       to specify a startdate
1295    o pkg/seaice:
1296     - update comments in SEAICE_OPTIONS.h (+ similar update of lab_sea/code and
1297       global_ocean.cs32x15/code versions).
1298     - turn on seaice Multi-category (in data.seaice, SEAICE_multDim=7) for
1299       verification experiment global_ocean.cs32x15.seaice and update results.
1300    o pkg/exf:
1301     - new S/R EXF_GETFIELD_START to return starting-time of a forcing field
1302       (according to useExfYearlyFields).
1303    o pkg/cal:
1304     - move calendar setting & summary (previously in cal_readparams.F) into new
1305       S/R CAL_INIT_FIXED to be called later in the initialisation process, once
1306       length of the simulation is set (after SET_PARMS call); This is an attempt
1307       to fix Pb when, e.g.: pkg/longstep, modifies the length of the run.
1308     - For safety: keep a record of pkg/cal parameter settings status
1309               to allow to STOP if one pkg/cal S/R is called too early.
1310     - add a stop in all basic pkg/cal subroutines if called before setting is done.
1311     - modify cal_getdate.F: stop when nothing was returned;
1312       if called with myIter=-1, simply retrun modelBaseDate (1,2 = startDate_1,_2);
1313       this allows to remove "cal.h" from seaice_read_parms.F & init_mnc_vars.F.
1314    
1315    checkpoint63l (2012/04/04)
1316    o pkg/bbl:
1317      - fix call to FIND_RHO_2D in bbl_calc_rho.F (case multi-tiles per proc);
1318        update global_with_exf output.yearly.txt file.
1319    o pkg/cal:
1320      - start to clean-up cal_set.F ; fix for the case where baseTime is non-zero.
1321      - remove 2 unsused and very short (1 line only) functions ;
1322      - remove unsused subroutines from AD-Diff list.
1323    o model/src:
1324      - start to implement clean wait to stop in initialization S/R (config_check.F,
1325         packages_check.F, ini_parms.F and pkg/obcs/obcs_check.F + pkg/mypackage)
1326    o folowing PRINT_MESSAGE changes:
1327      - remove reminder multiple print to the same file (STDOUT) when multi-threads.
1328    o pkg/bbl:
1329      - modification so it can work with z*
1330      - replace deltaT with dTtracerLev(k) for asynchronous time stepping
1331      - global_with_exf/input.yearly verification; changes output.yearly.txt
1332    o eesupp/src:
1333      - PRINT_MESSAGE: use OpenMP critical instruction (similar to PRINT_ERROR);
1334        writing to unit 0 (if unit=errorMessageUnit) extended to the case myThid=1
1335      - CHECK_THREADS: specific code if using OpenMP threading: improve checking of
1336        # of threads across processors (e.g., different env OMP_NUM_THREADS setting)
1337      - improve special preliminary call to EESET_PARMS (if eedata is read 2 times).
1338      - when using MPI, always set usingMPI=T ; set default accordingly and stop
1339        if not consistent.
1340      - ALL_PROC_DIE: add a BARRIER after MPI_FINALIZE call ; skip this when thread
1341        argument is zero (in case called within single-thread section).
1342    o pkg/fizhi:
1343        clean-up turbulence cold-start switch: decided in fizhi_init_vars.F, stored
1344        in common bloc (fizhi_coms.h) and then passed as argument up to S/R TURBIO.
1345    o pkg/exch2:
1346      - add argument "updateCorners" to S/R exch2_get_uv_bounds (enable to
1347        activate EXCH_IGNORE_CORNERS in vector EXCH S/R).
1348      - switch 1rst EXCH call to IGNORE_CORNERS (instead of UPDATE_CORNERS)
1349        but keep the 2nd with UPDATE_CORNERS: this prevents overwriting good data
1350        with bad ones coming from a not-yet-updated halo.
1351        This should fix the problem when sNx <> sNy and GCD(sNx,sNy) < 2*Olx.
1352    o pkg/frazil:
1353        move FrzForcT diag from frazil_diagnostics_state.F to frazil_calc_rhs.F

1355  o model/src/config_check.F: add a check for OLx>sNx/OLy>sNy  o model/src/config_check.F: add a check for OLx>sNx/OLy>sNy
