5      ==============================      ==============================
6    
7    o pkg/exf & pkg/thsice:
8      - In case Energy-Reference-Level (ERL) is used (temp_EvPrRn=0), account
9        for energy content of Precip + RunOff & Evap. Assumes:
10       1) Rain has same temp as Air.
11       2) Snow has no heat capacity (consistent with seaice & thsice pkgs)
12       3) Run-Off comes at the temp of surface water (with same Cp)
13       4) Evap over ocean is released to the Atmos @ surf-temp (=SST); should be
14        put directly into Latent Heat flux & should use water-vapor heat capacity.
15       5) Evap over snow/seaice (pkg/thsice) assumes constant Lf+Lv (consistent
16        with snow having no Cp) => water vapor is released to Atmos @ 0^oC (=ERL).
17    o pkg/seaice: simplify the use of CPP flags in JFNK-related files
18        (compile when SEAICE_ALLOW_JFNK is defined)
19    o pkg/thsice:
20      - fix oceanic flux diagnostics & timeave (left from new sequence of calls
21        implementation): move THSICE_AVE call after the advection (called directly
22        from thsice_do_advect.F).
23    o verification/global_ocean.90x40x15 and OpenAD:
24      New experiment for OpenAD is identical to the one in input_ad except that
25        multiDimAdvection=.FALSE.,
26      There is still an issue with this.
27    o pkg/thsice:
28      - account for ice velocity (ocean relative velocity) in turbulent heat flux
29        at the base of the ice; update output of global_ocean.cs32x15 (icedyn)
30        and offline_exf_seaice (main test).
31    
32    checkpoint64f (2013/03/31)
33    o verification/OpenAD:
34      - new (smaller, without OAD_DEBUG) output_oadm.txt generated using gfortran.
35    o verification/isomip, pkg/shelfice and OpenAD:
36      - add OpenAD setup to this exp and make shelfice package work with OpenAD
37    o verification/tutorial_global_oce_biogeo:
38      - update AD and TLM output after turning off ALLOW_FE (in DIC_OPTIONS.h)
39    o verification/offline_exf_seaice:
40      - replace adjoint experiment (now similar to fwd input.thermo/ setup).
41    o verification/tutorial_tracer_adjsens, pkg/ptracers and OpenAD:
42      - add OpenAD setup to this exp and make ptracers package work with OpenAD
43    o pkg/seaice/seaice_evp.F:
44       mask the asymmetric contribution of the ice-ocean stress (when
45       the turningAngle is non-zero) over open water to avoid stripes
46       in the EVP-solutions after many EVP-substeps. This does not change
47       the verification experiment (because turningAngle=0 in that experiment),
48       but will affect other EVP solutions with turningAngle.ne.0
49    o verification, AD & TLM output:
50      - new TAF version 2.3.10 (previously 2.3.8) add more parenthesis in multiple
51        additions and multiplications which affect results at machine truncation
52        level. Update few AD output (1D_ocean_ice_column, bottom_ctrl_5x5,
53        lab_sea.noseaicedyn & offline_exf_seaice) and TLM output
54        (1D_ocean_ice_column & tutorial_tracer_adjsens.som81) which had only 12
55        digits of matching.
56    o pkg/seaice:
57       modify lsr-algorithm so that it vectorizes AND converges by using a
58       "zebra" method: split vector loop into two with step size 2; this
59       solves a general convergence problem for the JFNK solver on a vector
60       computer. It has the potential to even improve convergence for
61       non-vector machines, but it does change the results so it is turned
62       off by default. To turn on define CPP-flags SEAICE_VECTORIZE_LSR and
63       SEAICE_VECTORIZE_LSR_ZEBRA in SEAICE_OPTIONS.h
64    
65    checkpoint64e (2013/03/05)
66    o pkg/ecco and several verification experiments:
67       Remove special versions of the_model_main.F, the_main_loop.F, forward_step.F
68       from ecco package, and revert to unified routine in model/src/
69       Adjust verification experiments accordingly, especially gloal_oce_llc90
70       Should conclude long-standing work by Gael to reconsile the_main_loop with
71       ECCO and will enable OpenAD's revolve loop in ECCO setup.
72    o pkg/generic_advdiff:
73      - implement compressible flow method for multi-dim advection (similar to
74        gad_som_advect.F); add new option "GAD_MULTIDIM_COMPRESSIBLE" (since
75        TAF generates many recomputations) to use it; no yet coded with implicit
76        vertical advection.
77      - change experiment advect_cs (new output) and advect_xy (same output)
78        to test compressible flow multi-dim advection.
79    o pkg/generic_advdiff:
80      - fix SOM advection for unusual cases (linear Free-Surf in r*, other
81        cases where linear Free-Surf is not @ k=1, e.g., useShelfIce)
82    o pkg/seaice:
83      - fix bug in the no-slip implementation in seaice_calc_strainrates.F, this
84        bug affects two verification experiments (lab_sea and lab_sea.hb87),
85        recover old (wrong) results by setting noSlipFac = 2. in
86        seaice_calc_strainrates.F;
87      - add another averaging method for etaZ (etaZmethod=3), a mix of 2 and 0
88      - add runtime parameter SEAICE_JFNKepsilon for that finite difference
89        gradient in the Jacobian times vector operation (s/r seaice_jacvec)
90      - fix line search in seaice_jfnk.F (s/r seaice_jfnk_update)
91    o pkg/seaice: reorganize seaice_lsr.F to be able to reuse more code:
92      - new subroutines seaice_lsr_tridiagu/v
93      - introduce loop bounds i/jmin/max to be able to use a restricted
94        additive Schwarz method, but not used for now.
95      - rename SEAICE_CALC_LSR_COEFFS into SEAICE_LSR_CALC_COEFFS
96      - use new subroutines seaice_lsr_tridiagu/v in s/r seaice_preconditioner
97    o OpenAD support
98       Reorganize S/R call for overall time-stepping loop to facilitate
99       OpenAD revolve loop replacement
100       (new S/R main_do_loop.F)
101    o model/src:
102      - add 3-D array 3rd dimension to argument list of S/R ADAMS_BASHFORTH2/3;
103      - pkg/cheapaml: remove local S/R ADAMS2d and use instead standard S/R
104        ADAMS_BASHFORTH2.
105    o pkg/cheapaml:
106      - add new parameter (default=F, same as before) to disable full domain
107        (including land) periodicity in X & Y dir.
108      - new S/R CHEAPAML_COPY_EDGES to copy relaxation field into edges of
109        prognostics field ; merge the 2 S/R cycle_2d_tracer and timestep_2d_tracer
110        into single S/R CHEAPAML_TIMESTEP.
111    
112    checkpoint64d (2013/02/17)
113    o pkg/monitor (angular momentum):
114      - do not add Eta contribution to the total AM if using rigid-lid;
115      - correct for Adams-Bashforth in zonal-wind part (instead of in AM_eta).
116      - horizontal discretisation: compute Zonal wind contribution separately for
117        each component (instead of from cell centered averaged) and use the 4
118        grid-cell corner averaged value of Omega*(R*cos_Phi)^2 in AM_eta part.
119      - Check that AM is conserved with linear dynamics (momAdvection=F and linear
120        FreeSurf) if using vectorInvariant momentum.
121    o model/src (horizontal grid):
122      - move initialisation of all horizontal grid arrays to null value
123        from specific horizontal grid S/R to main S/R INI_GRID;
124      - add 2 new arrays to project model C-grid velocity on to zonal direction
125        (similar to AngleCosC & -AngleSinC but at U and V point location) and
126        compute them in S/R CALC_GRID_ANGLES.
127    o pkg/seaice: replace a hard coded parameter by a runtime parameter
128        SEAICE_JFNK_tolIter
129    o pkg/seaice: introduce a restricted additive Schwarz (RAS) method in
130        preconditioner for JFNK (run LSR into the overlaps as far as possible,
131        i.e OLx/y-2, but overwrite the solution in the overlaps)
132      - extend loop range in seaice_calc_viscosity
133      - add new parameters SEAICE_OLx/y (default = OLx/y-2)
134      - add flexible loop ranges to seaice_preconditioner, seaice_calc_lsr_coeffs
135      - slightly modify loops in tridiagonal solver lsr-preconditioner
136      - by default remove the extra exchange in seaice_preconditioner with a
137        replacement of an undocumented CPP flag by SEAICE_PRECOND_EXTRA_EXCHANGE
138      - modify offline_exf_seaice so that old results without RAS are reproduced
139        for output.dyn_jfnk.txt
140      in seaice_fgmres.F (unrelated to RAS)
141      - add a cpp-flag option for a re-ordered mapping (potentially more
142        efficient), but because this changes the results, turn it off by
143        default
144      - replace the save statement by local common blocks
145    o utils/matlab:
146      - fix tile-offset in rdmnc.m when output was produced using EXCH2.
147      - update cs_grid/bk_line scripts to use load_grid.m (in utils/matlab)
148        instead of local script "load_cs.m".
149    o pkg/seaice:
150      - fix a serious bug in seaice_fgmres.F, s/r seaice_scalprod, connected
151        to the scalarProductMetric and the unrolling. By chance this does not
152        change the verification experiment, because of the particular domain
153        decomposition
154    o pkg/diagnostics:
155      - change default missing_value from UNSET_RL to -999.
156    o pkg/layers: improve vectorization of layers_fluxcalc.F
157      - step 1: split loops, make TatU/V 2D arrays. This alone reduces the cpu
158        time spent in this routine by more than a factor of 3 on an NEC-SX8
159      - step 2: replace search algorithm by a bisection algorithm found in
160        Press et al. Numerical Recipes in Fortran. This algorithm can be
161        vectorized and finds the correct bin in approx. log2(Nlayers) steps.
162        For now, use this algorithm only for TARGET_NEC_SX defined.
163      - moved the search algorithm into a separate subroutine, that is kept
164        within the same file for automatic inlining.
165      - modified catching potential errors
166    o pkg/ecco:
167      - add compile switches ALLOW_SHALLOW_ALTIMETRY and ALLOW_HIGHLAT_ALTIMETRY.
168    o model/src, pkg/autodiff, pkg/ctrl, pkg/grdchk :
169      - modifications for ALLOW_GENTIM2D_CONTROL
170      -- forward_step.F, the_main_loop.F : pass options and arrays for adjoint tapes.
171      -- load_fields_driver.F : add call to CTRL_MAP_GENTIM2D( myTime, myIter, myThid )
172      -- add xx_gentim2d0/1 in ctrl_ad_check_lev1_dir.h checkpoint_lev1_directives.h etc
173      -- use ctrl_swapffields.F (new) instead of exf_SwapFFields.F in ctrl_get_gen.F
174    o model/src:
175      - account for moist thermodynamics in (dry) potential temperature equation;
176        update results of experiments: aim.5l_cs (x2), fizhi-cs (std + aqualev)
177        and cpl_aim+ocn.
178      - also switch to standard compiler (gfortran, was using ifort previously)
179        for fizhi-cs experiments reference output.
180    o pkg/ctrl:
181      - 1st step toward generic time-varying control variable (2D) via CPP option
182        ALLOW_GENTIM2D_CONTROL
183      - note new namelist ctrl_nml_genarr in data.ctrl
184    o verification/global_ocean.cs32x15:
185      - switch off OLD_THSICE_CALL_SEQUENCE (both forward and AD code) to use new
186        thsice calling sequence and update "output.icedyn.txt" output file.
187    o pkg/ptracers:
188      - from Ryan A.: code to allow to restart a tracer at regular time interval
189        specifying a reset frequency and a reset-phase (for each tracers).
190    o pkg/thsice:
191      - implement new sequence of calls for thsice+seaice:
192          previously:   ice-Dyn,ice-Advect,ice-Thermo(thsice)
193          new sequence: ice-Thermo(thsice),ice-Dyn,ice-Advect
194      - allows (with temporary CPP option "#define OLD_THSICE_CALL_SEQUENCE"
195        in CPP_OPTIONS.h) to recover old sequence;
196      - update diagnostics for Intermediate State thsice diagnostics: now filled
197        just before advection (instead of just after advection in old sequence);
198      - update output of experiment offline_exf_seaice (standard test);
199      - in global_ocean.cs32x15 exp., postpone output.icedyn.txt update
200        by setting #define OLD_THSICE_CALL_SEQUENCE in CPP_OPTIONS.h
201    o pkg/aim_v23:
202      - use tiled array for aim_CO2 and surface wind speed for export to coupler;
203      - use standard pkg/mdsio routines to read & write CO2 pickup file;
204      - in-line S/R AIM_AIM2DYN_EXCHANGES in aim_do_physics.F;
205      - Implement new sequence of calls for seaice advection (with thsice and
206        seaice diffusion): do ice advection after ice-Thermodynamic (previously
207        was done before); change aim_do_physics.F (split the bi,bj loops block);
208      - use same CPP option (OLD_THSICE_CALL_SEQUENCE) to recover old sequence;
209    o pkg/thsice:
210      - add a missing EXCH of sIceLoad in thsice_main.F (ocean set-up) for the case
211        where just seaice diffusion is used without seaice-dynamics.
212    
213    checkpoint64c (2013/01/18)
214    o pkg/seaice:
215      - add a parameter JFNKres_tFac that can replace JFNKres_t
216        (= JFNKres_tFac*JFNKresidual before JFNK solver)
217      - add a line search option to the JFNK solver
218      - move update of u/vIce and computation of initial residual into a separate
219        routine (same file); makes the code a little easier to read (?)
220      - the line search requires computation of the residual and for some reason
221        I cannot do the update of u/vIce at the beginning of the Newton loop
222        without changing the results, so we move computation of the new residual
223        also to the end of the Newton loop, even without the line search
224    o pkg/mdsio:
225      - write missing value (corresponding to undefined array value) to meta files;
226        skip this if missing value is one (UNSET_RL would be a better value for the
227        case of undefined missing value but it's current the default missing-value);
228        Also update mdsio_read_meta.F (reading timeInterval & missing-value).
229    o pkg/exf & thsice:
230      - for diagnostics purpose, fill-up and update Qsw array (+ fill the
231        diagnostics) even when SHORTWAVE_HEATING is #undef;
232    o verification/cfc_example:
233      - turn on pkg/layers with pkg/diagnostics (to test pkg/layers and to
234        illustrate how to use it).
235    o verification/offline_exf_seaice:
236      in input: add SEAICErestoreUnderIce=.TRUE., and reduce size of forcing
237        files to only one time-record.
238      in input.thermo: narrow the 2 bands of low initial ice-concentration near
239        N & S edges; switch on SEAICErestoreUnderIce=T; use pkg/diagnostics for
240        snapshot output; same mcPheePiston value as in thsice with
241        surf-current=0.2m/s.
242      in input.thsice: similar set-up as in input.thermo (channel with same seaice
243        initial conditions).
244    o verification/cfc_example:
245      - update file "data" with more standard choice (default rotationPeriod,
246        exactConserv=T, reduce ivdc_kappa to 10, remove multiDimAdvection=F,
247        set deltaTFreeSurf to deltaTtracer) and update the output.
248    o pkg/layers:
249      - fix bolus part so that it compiles with #undef GM_BOLUS_ADVEC;
250      - ensure that "layers_bolus" is switched to False when useGMRedi=False.
251    o verification/offline_exf_seaice:
252      - set all {field}period to zero for constant-in-time forcing (not tested
253        anywhere else).
254    o verification/offline_exf_seaice:
255      - dyn_lsr  : use pkg/seaice S/R (instead of pkg/thsice) to advect sea-ice;
256      - dyn_jfnk : use pkg/thsice S/R (instead of pkg/seaice) to advect sea-ice.
257    o model/src:
258      - implement Finite-Volume method for (hydrostatic) presure gradient
259        from S.-J. Lin (QJRMS 1997), for atmosphere using sigma-coordinate.
260    o pkg/seaice: implement EVP* by Lemieux et al. (2012).
261      - In order to be compatible with the default EVP code, this requires changing
262        the EVP code around a little; and because any small change immediately
263        breaks the lab_sea.hb87 verification experiment, the reference output is
264        updated two times (each time the remaining aggrement was only 2 digits):
265        - after replacing 1/dt by 1*recip_dt with a precomputed recip_dt
266        - after replacing 1/(1+0.5*dt/tau) by a/(a+1), with a=2*tau/dt
267        The adjoint test lab_sea.evp also needed to be updated.
268      - Turn on EVP* by setting SEAICE_deltaTevp as before, and setting
269        SEAICEuseEVPstar=.true.; for EVP* SEAICE_deltaTevp does not need to be
270        a factor of SEAICE_deltaTdyn, and you can set the number of EVP steps
271        explicitly with SEAICEnEVPstarSteps (thereby overriding the default of
272        INT(SEAICE_deltaTdyn/SEAICE_deltaTevp)). Controlling EVP* is deliberately
273        kept obscure, because I need to test it a little more.
274    o pkg/cheapaml:
275      - fix few incorrect type (_RL/_RS) in subroutine calls.
276    o pkg/seaice:
277      - new S/R SEAICE_MAP_RS2VEC (similar to SEAICE_MAP2VEC) to map _RS arrays
278        to _RL vector; this fixes JFNK code when compiling with "-use_r4" option.
279    o model/src:
280      - add a warning if using select_rStar=2 with nonlinFreeSurf <> 4;
281        change (in input_ad*/data) select_rStar from 2 to 1 for AD verification
282        experiments global_ocean.cs32x15 & tutorial_tracer_adjsens (+ update output)
283    o pkg/cheapaml:
284      - replace "273.1 _d 0" by celsius2K in pkg/cheapaml/cheapaml.F and
285        update output of experiment cheapAML_box.
286      - store in CHEAPAML.h coeffs ssq[0:2] for saturation specific humidity,
287        and set them only in one place (cheapaml_readparms.F).
288      - replace "273.16 _d 0" by celsius2K & replace "3.14159 _d 0" by constant "PI"
289      - remove re-setting of main-model parameter "celsius2K" (in cheapaml_readparms)
290        and re-setting of cheapAML params "lath" & "p0" (in cheapaml_init_varia).
291    o model/src/the_main_loop.F:
292      - fix revision 129 : need both ALLOW_ECCO and ALLOW_ECCO_EVOLUTION.
293    o pkg/seaice:
294      - remove legacy branch code.
295      - retire SEAICE_GROWTH_LEGACY and SEAICE_CAP_HEFF accordingly.
296    o verification/*/code*/SEAICE_OPTIONS.h:
297      - remove documentation for retired CPP flags (SEAICE_GROWTH_LEGACY,
298        SEAICE_CAP_HEFF).
299    o pkg/cheapaml:
300      - use standard routine (S/R GET_PERIODIC_INTERVAL) to decide when it is time
301        to load new forcing fields.
302      - add missing "_d 0" where it's needed; + some editing (improve indentation).
303      - remove switch to "-r8" compiler option (no longer needed) in verification
304        cheapAML_box, keep same output (small trucation error differences).
305    o verification/offline_exf_seaice:
306      - add thermodynamics only test.
307    o verification/cheapAML_box:
308      - split the domain in 8 (2x4) tiles; add MPI and multi-threaded test;
309        keep same output (same 14 digits for cg2d).
310      - switch on "-r8" compiler option (some numerical values are missing
311        the "_d 0") and update output (only 6 digits for cg2d were preserved).
312    
313    checkpoint64b (2012/12/24)
314    o pkg/cheapaml:
315      - remove un-used variables (Qnet,EmPmR) from pickup files.
316      - store tendency of advected variables into cheapaml pickup file
317        and fix the AB-2 restart.
318    o verification/offline_exf_seaice and lab_sea adjoint:
319      - switch to new code (#undef SEAICE_GROWTH_LEGACY).
320      - switch to 4 time steps in offline, consistent with lab_sea.
321      - match parameters from SEAICE_GROWTH_LEGACY branch in data.seaice.
322      - update results after change of experiment seaice.
323    o pkg/seaice:
324      - remove option SEAICE_MULTICATEGORY; has been replaced with run-time
325        parameter SEAICE_multDim. Issue a warning if SEAICE_MULTICATEGORY is
326        still defined since SEAICE_multDim needs to be set to MULTDIM value (from
327        SEAICE_SIZE.h) to recover previous #define SEAICE_MULTICATEGORY default.
328    o model/src:
329      - add run-time parameter to select CG2D solver minimum-residual solution
330        (in case of a poor convergence).
331    o pkg/seaice/seaice_lsr.F
332      - move calculation of matrix coefficients into new
333        S/R SEAICE_CALC_LSR_COEFFS; for now this routine remains in the same
334        file; the main purpose of this change is to be able to reuse the code
335        in S/R SEAICE_PRECONDITIONER
336      - modify the computation of the residual so that the mass of sea-ice
337        is not used twice; this simplifies the calculations, but since
338        the residual is never used except when LSR_mixIniGuess.ge.4---and this is
339        not tested in testreport---this does not affect the testreport results.
340    o verification/seaice_obcs:
341      - disable SEAICE_GROWTH_LEGACY; reset input files to match those of
342        verification/lab_sea/input.salt_plume; changes results/output.txt*
343    o model/src:
344      - adapt quasi-hydrostatic formulation to work with p or p* coordinate.
345    o pkg/seaice:
346      - improve description of parameters in seaice_fgmres.F and start
347        cleaning up the code
348      - change name of SCALPROD to SEAICE_SCALPROD and modify meaning of
349        second argument
350      - add a metric based on grid cell area to SEAICE_SCALPROD; update
351        results of offline_exf_seaice.dyn_jfnk
352      - compute initial residual norm in seaice_jfnk based on SEAICE_SCALPROD
353    o pkg/aim_v23:
354      - fix an other bug in dissipation heating (grid-cell area was missing).
355    o model/src + pkg/seaice:
356      - add global (multi-tile) linear solver for pair of tri-diagonal system
357        along X and Y lines, respectively for U and V component.
358        Note: 1) MPI and cube-exchange not yet coded.
359            2) probably not accurate for poorly conditioned / large size problem.
360      - add option for SEAICE_LSR to use global (multi-tile) tri-diagonal solver;
361        default: not compiled and not used.
362    o pkg/seaice:
363      - first attempt at a multi-threaded fgmres solver for the JFNK solver:
364        introduce bi/bj loops and use global_sum_tile_rl instead of
365        mpi_allreduce in seaice_fgmres.F
366      - improve diagnostics output for fgmres solver (seaice_fgmres.F)
367      - replace a few unnecessary goto statements by if-blocks  (seaice_fgmres.F)
368      - add a verification experiment for JFNK in offline_exf_seaice
369    o verification:
370      - change (for now, only fwd test) offline_exf_seaice experiment:
371        use a re-entrant channel with idealized coastline (trapezoidal shape)
372        at southern boundary to explore seaice dynamics and thermodynamics
373        with simple forcing. Main set-up has dynamics+thermo and SST relaxation;
374        secondary test (input.thsice) use thermodynamics only with SST relaxation.
375      - add seaice-dynamics only secondary test using LSR and pkg/thsice advection.
376    o pkg/exf:
377      - disable "sstExtrapol" when Nr=1
378    o verification:
379      - add new experiment "cheapAML_box" (simple 1 layer set-up from Bruno Deremble)
380        to test pkg/cheapaml.
381    o pkg/aim_v23 & pkg/shap_filt:
382      - fix dissipation heating (erroneous gravity multiplication factor).
383    o pkg/seaice:
384      - remove unused field pressPre from jfnk solver
385      - rename two subroutines in seaice_preconditioner.F
386    o eesupp/src:
387       - S/R MDSFINDUNIT avoids reserved unit numbers (scrUnit1, eeDataUnit ...)
388    o pkg/seaice/seaice_preconditioner.F: fix preconditioner once again
389       - remove wrong parts of the rhs and the lhs (were in there
390         because I did not understand the concept of this preconditioner)
391       - add an exchange between u- and v-sweep. This increases communication
392         by a factor of two but improves the convergence of jfnk. Ideally,
393         one would like the u- and v-sweep to be independent. So far within
394         undocumented ifdefs
395       - reorganize the extra computations for printing the residuals
396    o tools/genmake2:
397      - comment out the "mpif.h" include in NetCDF test programm (for MPI built)
398        since it's not necessary (and was preventing to use MNC in some cases).
399    
400    checkpoint64a (2012/11/16)
401    o pkg/autodiff:
402      - improve pkg-internal logical parameter switch (inAd/inFwd mode) so that
403        autodiff_readparms.F no longer depends on calling order (within
404        packages_readparms.F) and no longer requires to include ${PKG}_PARMS.h):
405        rename param turnFreeDriftInAdMode to SEAICEuseFREEDRIFTswitchInAd
406        and change param SEAICEuseDYNAMICSinAdMode to SEAICEuseDYNAMICSswitchInAd.
407    o pkg/obcs:
408      - adding tidal velocity forcing capability to obcs
409        for usage example, see verification/seaice_obcs/input.tides
410    o pkg/seaice:
411      - turn the LSR-relaxation parameters WFAU/V into runtime parameters
412        SEAICE_LSRrelaxU/V
413      - introduce runtime parameter SEAICEetaZmethod (=0 by default)
414    o pkg/aim_v23:
415      - implement heating from friction (bottom friction and stratospheric drag).
416    o pkg/shap_filt:
417      - fix diagnostic "SHAP_dKE" (was 2 time smaller); implement heating from
418        dissipation but only for Shap_funct=2, active when addFrictionHeating=T.
419    o model/src:
420      - move AddMass common block from DYNVARS.h to FFIELDS.h; allow to read-in
421        time-constant addMass field from file (addMassFile);
422      - support for heating due to friction (and Kinetic Energy dissipation):
423        add option, run-time switch and 3-D field array + support code ; each pkg
424        or S/R can add heating contribution (if there is a sink of KE); the sum is
425        accounted for as a Temperature tendency term (EXTERNAL_FORCING_T).
426    o pkg/seaice:
427      - complete merge of ITD code into seaice_growth.F
428        from MITgcm_contrib/torge/itd/code/
429        no verification so far, but Torge Martin tested
430        "1-D test case and Beaufort set up;
431        deliver okay results after 1 model year."
432      - complete merge of SEAICE_SIZE.h into all relevant routines
433      - move computation of eta at Z-points into calc_viscosities
434        + introduce global field etaZ
435        + add different methods for computing etaZ, for now the old
436          method (simple averages of eta to Z-points) is hardwired
437        + replace etaMeanZ by etaZ in seaice_lsr, seaice_calc_residual,
438          seaice_preconditioner
439      - simplify computations for SEAICE_ZETA_SMOOTHREG
440      - seaice_preconditioner:
441        + replace one remaining press by pressLoc (mistake)
442        + adjust printing of residuals
443      - improve I/O of diagnostics of JFNK in seaice_jfnk.F:
444        + add (SEAICE.h) and rename some counters (initiliased in
445          seaice_init_fixed.F)
446        + add _BEGIN/END_MASTER (myThid)  around print statements
447        + print total number of iterations and failures over SEAICE_monFreq
448          interval to STDOUT
449      - move control over output-messages by fgmres to seaice_jfnk to save
450        some operations
451      - move resetting initial guess for fgmres outside of seaice_fgmres_driver
452        in order to make restarts with sol .ne. zero (fgmres with restarts)
453        (seaice_jfnk.F, seaice_fgmres.F)
454      - seaice_calc_l/rhs.F: replace maskW/S by maskInW/S; this fixes
455        a serious convergence problem when open boundaries are involved
456    o pkg/ggl90: fix computation of control volumes for the case of
457      ALLOW_GGL90_HORIZDIFF (probably not used very often): move control volumes
458      up half a grid cell from C-centered to W-centered (pointed out by C. Eden)
459    o pkg/seaice: simplify seaice_evp by avoiding use of extra fields u/vIceC
460    o pkg/autodiff
461      - Add inAdMode switch for SEAICEuseDYNAMICS:
462        SEAICEuseDYNAMICSinAdMode
463        (extend logic in ADAUTODIFF_INADMODE_SET)
464    o pkg/seaice
465      - Step 1 of merging ice-thickness distribution (ITD) code from
466        MITgcm_contrib/torge/itd/ (author: Torge Martin)
467        The code implements concept laid out in Thorndike et al. (1975);
468        code is enabled via CPP flag SEAICE_ITD
469        nITD (in SEAICE_SIZE.h) defines number of ice thickness categories;
470        code is not complete yet!!
471      - SEAICE_SIZE.h now included in almost all seaice routines
472    o verification (using seaice):
473      - switch back seaice-dynamics (+ lower SOLV_MAX_ITERS) in ADM exp.
474        global_ocean.cs32x15.seaice ; update results.
475      - compile B-grid dynamics in FW test exp 1D_ocean_ice_column ;
476      - compile C-grid dynamics with #define SEAICE_ALLOW_JFNK in FW test exp
477        offline_exf_seaice (previously compiling B-grid).
478    o pkg/exf:
479      - fix some STOP conditions in exf_check.F (from Aug 28, modifs did not allow
480        to specify neither just 1 comp of wind or wind-stress, nor no surface momentum
481        forcing): just replace CPP option ALLOW_ATM_WIND with run-time param useAtmWind.
482    o pkg/layers (adjust changes from Sept 19):
483      - do snap-shot output and fill diagnostics from inside iLa loop (layers_calc.F)
484        this allows to remove "layers_maxNum" dimension from all layers arrays.
485    o pkg/layers (adjust changes from Sept 19):
486      - remove ALLOW_LAYERS_OUTPUT ; fix snap-shot and time-ave output ;
487      - snap-shot extended to all type of layers (not just the 1rst type);
488      - remove layers variables when corresponding CPP option is undef.
489    o pkg/layers:
490      - rename pkg/layers variable and add new output (layer exist & un-weighted
491        velocity in layer)
492    o pkg/seaice:
493      - simplify (?) ocean-drag coefficent computations by using
494        the same routine in all three solvers (saves some code lines)
495      - remove global fields DRAGA and DRAGS from C-grid code and
496        declare them locally in lsr.F (the only place where they are
497        still used)
498      - update AD output of lab_sea.evp (very sensitive anyway).
499    o pkg/seaice: add Jacobian-free Newton Krylov solver for ice dynamics
500      (Lemieux et al. 2010, 2012). Turn on with the usual SEAICE_ALLOW_JFNK
501      and SEAICEuseJFNK=.true. A few things to note:
502      - involves a FGMRES, that is parallel but very inefficient,
503        because of many scalar products (global sums) in the Gram-Schmidt
504        orthogonalization method. Needs to be replaced. Original code
505        from J.-F. Lemieux
506      - preconditioner for FGMRES is a stripped down version of LSOR
507      - SOLV_MAX_ITERS is now used for LSOR as a solver and as a
508        preconditioner. For the preconditioner, the default is set to 10.
509      - Jacobian times vector is computed with finite differences
510      - marginally related to JFNK-solver: add a smooth regularization for
511        zeta with tanh that will improve convergence (Lemieux and Tremblay,
512        2009) for any implicit solver (not implemented for EVP because EVP
513        does not need this regularization in the first place). Define
514        SEAICE_ZETA_SMOOTHREG in SEAICE_OPTIONS.h to use.
515    o eesupp/src:
516      - check in genmake2 that intrinsic S/R flush is available.
517      - add S/R to flush IO unit (if intrinsic S/R flush is available)
518      - flush standard & error msg unit before MPI termination
519      - if debugMode, flush IO unit after printing msg
520    o pkg/ctrl:
521      - ctrl_unpack.F, ALLOW_GENARR3D_CONTROL code: fix missing argument in call
522        to ctrl_set_unpack_xyz.
523    
524    checkpoint64 (2012/10/09)
525    o pkg/shelfice
526      - in mom_fluxform.F, mom_vecinv.F:
527        CALL SHELFICE_V_DRAG(bi,bj,k,vFld,KE,KappaRU,vF,myThid)
528        Bug fix KappaRU -> KappaRV
529        does not change verification/isomip but may change other setups
530        (presumably constant KappaRU=KappaRV)
531      - fix diagnostics SHIU/Vdrag (thanks to Tom Millgate)
532    o pkg/obcs:
533      - fixed some indexing bugs in obcs_seaice_sponge.F
534      - added obcs relaxation subroutines for HSALT and HSNOW
535      - changes verification/seaice_obcs/results/obcs_seaice_sponge.F
536    o pkg/seaice:
537      - add "multicategory" parameterization for snow in analogy to ice,
538        default is off for now.
539    o pkg/obcs:
540      - added obcs_seaice_sponge.F for obcs relaxation of seaice variables;
541        see verification/seaice_obcs/input.seaiceSponge for example application.
542      - remove local commom bloc "OBCS_GLOBAL" in obcs_readparms.F and do all the OB
543        index setting by master-thread. This fix multi-threads Pb in previous modifs.
544    o pkg/layers :
545      - add diagnostics to pkg/layers
546      - move the meat of pkg/layers from layers_calc.F to layers_fluxcalc.F
547        (from R.Tulloch). Layers_calc.F now calls layers_fluxcalc.F accordingly.
548    o pkg/generic_advdiff/gad_implicit_r.F :
549      - fix ADVr diagnostics in case of both implicit vertical advection and diffusion.
550    o pkg/seaice/seaice_growth.F:
551      - fix SItflux diagnostics in virtual salt flux + balanceEmpmr case.
552    o pkg/obcs:
553      - change default setting of OBCS_UVICE_OLD from defined to undef;
554      - use new parameter OB_indexNone for null index value (instead of hard-coded 0)
555        in all pkg/obcs code and in other pkgs; remove k loop in obcs_check_depths.F;
556      - pass OB_indexNone as (new) argument to S/R CTRL_MASK_SET_[X,Y]Z;
557      - change OB null index value (OB_indexNone) to -99 ; this fix the problem
558        with Southern & Western OB at a tile edge (at least in a simple set-up).
559    o pkg/obcs:
560      - change settings of OB index in case OB coincides with tile edge (shared by
561        2 tiles), so that common OB location is registered by both tiles (instead of
562        only 1). However, for Southern and Western OB, index value = 0 is not
563        recognized as valid OB index (=default null value) and needs to be fixed.
564      - modify accordingly OBCS_BALANCE_FLOW and OBCS_MONITOR (avoid double counting)
565      - new parameter "OB_indexNone" for null index value (for now, still zero)
566        to replace hard-coded null index value of zero.
567    o pkg/exch2:
568      - improve W2_USE_E2_SAFEMODE (faster) and W2_E2_DEBUG_ON:
569        always check buffer-size (but outside the loop); move checking for valid
570        index from W2_USE_E2_SAFEMODE to W2_E2_DEBUG_ON; in W2_E2_DEBUG_ON,
571        print each tile and point connection only if |W2_printMsg|>= 2 and 3.
572    o pkg/ctrl (pack & unpack):
573      - in ctrl_pack.F & ctrl_unpack.F, use the same local file-name variable
574        (locally defined) for different variables (+ remove the variable-specific
575        file name in CTRL_GENARR.h). For now, only implemented for GENARR2/3D_CONTROL
576        (to be extended to other local file names in ctrl.h).
577    o pkg/flt:
578      - add a FLT_Iter0 option (similar to PTRACERS_Iter0).
579    o pkg/mdsio:
580      - fix missing STOP in mdsio_readvec_loc.F (case ioUnit=0) when file is missing
581    o tools/genmake2:
582      - add similar dependences for target EXE_AD & EXE_FTL as we have for EXECUTABLE
583        (added by Alistair in version 1.51 for building without make depend);
584      - remove Header files list (H_SRC_FILES) from the dependence of targets
585         ad_input_code.f & ftl_input_code.f (not clear why it was added in the first
586        place in version 1.23): this save going through staf when unrelated header
587        file has been modified.
588       Note: for an intermediate target (e.g., ad_input_code.f or adtaf) without
589        "make depend" step, still need to do "make links" before "make adtaf".
590    o eesupp/src (+ few pkg src files) & genmake2:
591      - finish to remove ALWAYS_USE_MPI in source code that TAF does not see;
592      - no longer set ALWAYS_USE_MPI in Makefile (was done by genmake2).
593      - improve genmake2 checking for ALLOW_${PKG} in CPP_OPTIONS.h files (distinguish
594         upper/lower case ; account for space between "#" and undef/define)
595    o pkg/flt (with exch2):
596      - cleaning: fix so that it compiles; move remaining MPI calls out of flt_exch2.F;
597      - simplify threads synchronisation; fix (many issues) multi-threaded with MPI.
598    
599    checkpoint63s (2012/09/05)
600    o pkg/ecco:
601      - remove #ifdef ALLOW_SMOOTH_CORREL3D brackets.
602      - add more relevant #ifdef ALLOW_SMOOTH ones.
603      - sort out useAtmWind, useSMOOTH, ctrlSmoothCorrel2D.
604    o pkg/ctrl:
605      - CTRL_OPTIONS.h : document CPPs related to smoothing; ALLOW_SMOOTH_CORREL2D/3D,
606        ALLOW_CTRL_SMOOTH, ALLOW_SMOOTH_CTRL2D, ALLOW_SMOOTH_CTRL3D.
607      - ctrl.h : document run time params doInitXX, doMainPack, doMainUnpack, doPackDiag,
608        doSinglePrecTapelev (audodiff param!), ctrlSmoothCorrel2D (new) and
609        ctrlSmoothCorrel3D (new).
610        The added ctrlSmoothCorrel2D/3D replace the old ALLOW_SMOOTH_CORREL2D/3D CPP.
611      - ctrl_readparms.F : initialise ctrlSmoothCorrel2D/3D and read from namelist.
612      - ctrl_init.F ctrl_pack.F ctrl_unpack.F : switch off ustress/vstress
613        controls when useAtmWind, and vice versa.
614      - ctrl_map_ini_ecco.F : UVEL0, VVEL0, edtaux, edtauy cannot be smoothed as tracers.
615      - ctrl_get_gen.F : replace #ifdef ALLOW_SMOOTH_CORREL2D with
616          #ifdef ALLOW_SMOOTH, IF ctrlSmoothCorrel2D, IF useSMOOTH.
617      - ctrl_map_ini_gen.F : replace #ifdef ALLOW_SMOOTH_CORREL3D with
618          #ifdef ALLOW_SMOOTH, IF ctrlSmoothCorrel3D, IF useSMOOTH.
619      - ctrl_set_pack_xy[z].F, ctrl_set_unpack_xy[z].F:
620        replace ALLOW_SMOOTH_CORREL2D/3D brackets with ctrlSmoothCorrel2D/3D.
621    o pkg/smooth:
622      - remove un-necessary includes.
623      - remove ALLOW_SMOOTH*D and ALLOW_SMOOTH_CORREL*D brakets.
624        Those CPP options were never defined, and not necessary.
625    o model/src:
626      - fix CPP brackets in ini_mixing.F (GM_background_K belongs to gmredi).
627      - standard treatment of useSMOOTH.
628    o pkg/autodiff:
629      - add LOGICAL useGGL90inAdMode, useGGL90inFwdMode, useSALT_PLUMEinAdMode,
630        useSALT_PLUMEInFwdMode allowing to switch off ggl90 and salt_plume adjoint.
631    o pkg/exch2:
632      - add "if usingMPI" where it was missing (in exch2_rx?_cube*.template)
633        + start to remove ALWAYS_USE_MPI in source code that TAF does not see.
634      - make new S/R W2_MAP_PROCS out of w2_eeboot.F to setup exch2 CommonFlag
635        and tiles to process mapping.
636      - re-arrange 3 header files (W2_EXCH2_PARAMS.h, _BUFFER.h & _TOPOLOGY.h)
637        moving /EXCH2_FILLVAL_RX/ & /W2_EXCH2_COMMFLAG/ to W2_EXCH2_TOPOLOGY.h;
638        rename "exch2_tProc" to "W2_tileProc" and move seting of e2FillValue_RX
639        from w2_eeboot.F to w2_readparms.F.
640    o eesupp/src:
641      - set exchNeedsMemsync & exchUsesBarrier according to "usingMPI" (instead of
642        ALWAYS_USE_MPI) + moved from ini_communication_patterns.F to eeset_parms.F;
643        also move setting of exchCollectStatistics from exch_init.F to eeset_parms.F
644      - in eedie.F and all_proc_die.F, always call MPI_FINALIZE when ALLOW_USE_MPI
645        is defined (remove condition on usingMPI) to match cases where MPI_INIT
646        has been called.
647      - fix bug I put in previous modif of exch_sm_3d_rx.template (not much used);
648      - change default (non-MPI) value of myPid (from 1 to 0) to match MPI settings
649        (so that on 1 proc, get same myPid independently of usingMPI)
650      - add a stop if multi-procs but usingMPI=F ; stop also if usingMPI=T and
651        useCubedSphereExchange with EXCH-1 (safer).
652      - add "if usingMPI" where it was missing (+ start to remove ALWAYS_USE_MPI).
653    o pkg/ggl90:
654      - fix bug in filling corner mask array "mskCor" (FILL_CS_CORNER_TR_RL call)
655        used in ALLOW_GGL90_SMOOTH code.
656    o pkg/flt:
657      - fix typo in FLT_WITHOUT_Y_PERIODICITY (the effect was to ignore stopping
658        floats at the Southern end of the domain).
659    o eesupp/inc:
660      - add a list of CPP-options which can be set by Makefile (DEF_IN_MAKEFILE.h);
661        but not used (and not to be used) anywhere, just for documentation.
662    o pkg/autodiff, exf, ptracers & seaice (AD & TL output):
663      - comment out the very nasty "writeBinaryPrec = writeStatePrec" line, since:
664        a) can damage previously written records in any other multi-record files.
665        b) if needed, can easily do it cleanly, by calling S/R WRITE_REC_3D_RL/S.
666    o tools/genmake2:
667      - define variable MAKE within Makefile and use it in place of 'make';
668      - update AD_CONFIG.h (if needed) before building any of the executable
669        (forward, adjoint or tangent-lin); this involves a 2nd invocation of make;
670        and add the usual #ifndef/#define AD_CONFIG_H in AD_CONFIG.h;
671      - always print usual warning comment 'this file is automatically generated'
672        from script convert_cpp_cmd2defines (+ remove this warning from genmake2).
673    o pkg/cheapaml:
674      - updated to correspond to the code used in accepted paper (Nico Wienders).
675    o pkg/exf:
676        added run time switch useAtmWind to replace ALLOW_ATM_WIND cpp switch.
677        ALLOW_ATM_WIND now just sets the useAtmWind default (see exf_readparms.F)
678        and force defines ALLOW_BULKFORMULAE (EXF_OPTIONS.h).
679    o pkg/exf, autodiff, ctrl, ecco and seaice:
680        remove ALLOW_ATM_WIND brackets, or replace them with useAtmWind ones.
681    o pkg/ctrl, ecco:
682        allow to compile both ALLOW_U/VSTRESS_CONTROL and ALLOW_U/VWIND_CONTROL.
683        Depending on useAtmWind, one is inactive, and the other is active (see
684        exf_getffields.F/exf_getsurfacefluxes.F).
685    o tools/genmake2:
686      - improve error msg when failing in 2nd test of check_for_broken_Ff
687      - fix option '-makefile' short-name (-mf according to genmake2 -help)
688      - source local config file "genmake_local" just after processing the genmake2
689        command arguments (previously done before processing arg).
690    o pkg/grdchk:
691      - add a call to TURNOFF_MODEL_IO for Tangent-Linear run (in this case, call
692        to this routine from cost_final has been dropped in g_cost_final)
693      - improve printed information (more explicit msg, no longer using "print *,"
694         fix fcpertminus printed value).
695    o model/src:
696      - move call to COST_INIT_VARIA out of packages_init_variables.F directly
697        into initialise_varia.F (just after calling PACKAGES_INIT_VARIABLES):
698        this prevents getting cost-funct reset in adinitialise_varia recomputations.
699    o pkg/dic:
700      - move initialisation of "freefe" array from from dic_biotic_forcing.F to
701        fe_chem.F: this prevents TAF from dropping this initialisation in TLM code.
702    o pkg/grdchk:
703      - grdchk_main.F : added CALL GLOBAL_SUM_INT( ierr , myThid )
704      - grdchk_getadxx.F etc. : omit I/O if ierr.EQ.0
705    o pkg/autodiff/ctrl/grdchk :
706      - attempt to sort out what works and what does not,
707        with regard to I/O, and to warn/stop accordingly.
708    o pkg/grdchk:
709      - attempt to fix grdchk in the case of useSingleCpuIO.
710      - "if ( myProcId .EQ. grdchkwhichproc .AND. ierr .EQ. 0 )"
711       statements were moved from grdchk_main.F and into
712       grdchk_getadxx.F grdchk_getxx.F grdchk_setxx.F.
713      - a global sum is applied to record numbers icvrec/layer
714       out of grdchk_loc so that they be passed to I/O routines.
715    o pkg/smooth:
716      - fix recomputation that appeared with nlfs : use smooth_recip_hFacC,
717        smooth_hFacW, smooth_hFacS (copied at init_fixed) in 3d case.
718    o verification/testreport:
719      - add option '-tlm' for Tangent-Linear test (-adm,-oad,-tlm are all exclusive);
720      - can also use compressed (gzip) reference output file;
721      - change format (in pkg/grdchk) of TLM output (+ add forward gradient)
722        to be easier to collect by testreport.
723      - update existing TLM output (half out-of-date by more than 3 yrs).
724      - report NETCDF & LAPACK settings (from genmake2) in output dir.
725      - report run-time in each individual summary (previously only for AD test);
726        for TLM test, add also TAF version.
727      - add daily TLM test on (old) aces cluster + weekly test on baudelaire.
728    
729    checkpoint63r (2012/08/15)
730    o tools/genmake2:
731      - fix Makefile for target ftlall (+ update files to clean after make ftlall)
732    o pkg/ecco/ecco_cost_final.F :
733      - fix fc print statements (to stdout and costfunction0000) so
734        that the printed value is always after the global sum.
735    o pkg/seaice/seaice_dynsolver.F :
736      - fix ice strength assymptote at SEAICE_area_max<1
737        (no change for the standard case of SEAICE_area_max=1)
738    o some cleaning:
739      - pkg source files: ensure that all *.F files from each pkg included the
740        corresponding ${PKG}_OPTIONS.h file (except stand-alone src file which
741        only includes CPP_EEOPTIONS.h); fix S/R CTRL_SMOOTH ; update AD experiment
742        code_ad/*.F src files; add new option-file in pkg/admtlm + corresponding
743        includes;
744      - model/src: add PACKAGES_CONFIG.h wherever ALLOW_AUTODIFF[_TAMC] is used.
745      - ALLOW_DIFFKR_CONTROL: add a stop in S/R CTRL_CHECK in case ALLOW_3D_DIFFKR
746        is undef; also define /DYNVARS_DIFFKR/ common block in DYNVARS.h when
747        ALLOW_DIFFKR_CONTROL is defined, to allow to compile and reach this stop.
748      - update option-file CPP_OPTIONS.h of all AD experiments:
749        * no longer include PACKAGES_CONFIG.h ;
750        * includes ECCO_CPPOPTIONS.h if PACKAGES_CONFIG.h has been included ;
751        * def/undef ALLOW_3D_DIFFKR independently of ALLOW_DIFFKR_CONTROL (before
752          including ECCO_CPPOPTIONS.h).
753    o pkg/cost, pkg/ctrl, pkg/ecco option-file:
754      - clean-up and split content of old pkg/ecco/ECCO_CPPOPTIONS.h file into
755        separated pkg option-file (done according to old doc from ECCO_CPPOPTIONS.h,
756        not necessary accurate).
757      - add a template for option-file ECCO_CPPOPTIONS.h, mostly empty, in
758        pkg/autodiff, i.e., the 1rst pkg to compile for adjoint built, with lines to
759        deliberately break compilation (a remainder that it needs to be customized)
760      - in pkg/ecco, includes ECCO_OPTIONS.h instead of COST_OPTIONS.h
761      - rename COST_CPPOPTIONS.h to COST_OPTIONS.h
762      - rename CTRL_CPPOPTIONS.h to CTRL_OPTIONS.h
763    o tools/genamke2:
764      - check for lapack.
765    o pkg/cost and pkg/ecco : attempt to sort out some of the limiting intricacies.
766      - pkg/cost.cost_final.F : allow for use of pkg/ecco and pkg/cost cost functions
767        jointly. The exclusive ifdefs were removed, to add costs terms (when defined)
768        from both packages.
769      - the fc global sum in pkg/ecco/ecco_cost_final.F was removed accordingly.
770      - for objf_atl we use either the pkg/ecco or the pkg/cost term depending on CPPs.
771      - pkg/ecco and model/src : add CPP brackets around pkg/cost and pkg/ctrl includes
772        of "CTRL_SIZE.h" "ctrl.h" "ctrl_dummy.h" "optim.h" / "cost.h" accordingly.
773    o pkg/cost : add comments to explain special and/or untested setups.
774    o pkg/exf:
775      - use EXF_OPTIONS.h to set pkg/exf options except if done in ECCO_CPPOPTIONS.h
776        (previously, ALLOW_AUTODIFF_TAMC was controling this switch).
777    o verification/*/code_ad:
778      mimimal cleaning of AD experiments ECCO_CPPOPTIONS.h option-file:
779      - reccord when this file is included (define ECCO_CPPOPTIONS_H)
780      - remove the most obvious obsolete features (e.g., #define ALLOW_COST not
781        allowed since Oct 2003 in any option-file except in PACKAGES_CONFIG.h)
782    o pkg/seaice :
783      - added possibility to change ice strength/PRESS0 relationship to
784        HEFF, according to the following run time parameters
785        SEAICEpresPow0 :: HEFF exponent for ice strength below SEAICEpresH0 (integer, >0)
786        SEAICEpresPow1 :: HEFF exponent for ice strength above SEAICEpresH0 (integer, >0)
787        SEAICEpresH0   :: HEFF threshold for ice strength            (m)
788    o pkg/ggl90 :
789      - added run time flag mxlSurfFlag to include the code that ensure
790        mixing between first and second level (previously included as a comment)
791    o verification/1D_ocean_ice_column/input_ad/data.autodiff :
792      - add test of newly added dumpAdByRec=T option where
793        we write all records to one file per variable.
794    o verification/global_ocean.cs32x15/code_ad/CPP_OPTIONS.h :
795      - switch to #define ALLOW_BALANCE_RELAX and ALLOW_BALANCE_FLUXES
796        to check that this code is ok with taf and compiles in adjoint.
797    o pkg/autodiff :
798      - added run time param dumpAdByRec : ad dump format switch.
799        If true then write all records to one file per variable.
800        Else write one file per record (remains the default).
801      - revise seaice_ad_dump.F and exf_adjoint_snapshots_ad.F accordingly.
802    o pkg/seaice:
803     - Added SEAICEuseTILT run time switch : if set to
804       false then omit the tilt term in seaice dynamics.
805     - Fix free drift calculation.
806    o pkg/shelfice:
807      When initializing SHELFICEDragQuadratic, set default to be
808      consistent with shiCdrag in case SHELFICEuseGammaFrict is used,
809      but retain option to set it independently
810      (inconsistenty spotted by Veronique Dansereau)
811    o eesupp/inc:
812      - in EEPARAMS.h, add real-type constant for some frequently used simple number
813         (0,1,2,1/2), with name explicitly referring to RS/RL type.
814    o model/src:
815      - move balancing of relaxation terms to new S/R balance_relax.F.
816    o pkg/autodiff:
817      re-write active I/O high-level (control) S/R:
818      - rename  S/R ACTIVE_READ/WRITE_RL to ACTIVE_READ/WRITE_3D_RL
819      - add 1 more argument (useCurrentDir) to replace the "_LOC" 2nd set of S/R.
820      - use standard pkg/mdsio I/O routines (MDS_READ/WRITE_SEC_XZ/YZ  and
821        MDS_READ/WRITE_FIELD); change loops to multi-threads.
822      - update and merge active_file_control_slice.flow into active_file_control.flow
823      - update the calls in lower level S/R (active_file.F, active_file_g.F and
824        active_file_ad.F) keeping the argument list and function unchanged.
825      - also update lower-level "_LOC" version (call same S/R with "useCurrentDir
826        =.TRUE.") and remove high-level (control) _loc version (not called anymore).
827      - new low-level active I/O routines, one for each type (RL/RS), for active var
828        of various (XY,XZ,YZ) shape and level number (arguments: arrShape, myNr);
829        fix ctrl_init_wet.F & ecco_cost_weights.F by calling the new S/R with the
830        right type.
831    o autodiff and RS=real*4:
832      - call the right type (_RS instead of _RL) of S/R in few output S/R (pkg/exf
833        ad-monitor and snapshots); disable arrType='RS' in mdsio_gl*.F ;
834      - change argument type of 3-D mask argument to _RS to match type in the call
835        (in seaice_cost*.F, ctrl_*_gen.F and *ctrl_bound.F); to be continued.
836    o pkg/thsice:
837      - re-anable balanceEmPmR when useSEAICE=T with useThSIce=T.
838      - option to correct ocean fresh-water flux for imbalance of Atmos+Land
839        fresh-water flux: uniform correction or proportional to local precip.
840    o pkg/ctrl:
841      - new header file CTRL_SIZE.h for parameters maxCtrlArr2D, maxCtrlArr3D
842      - redefine CPP option ALLOW_BOTTOMDRAG_CONTROL to
843                            ALLOW_BOTTOMDRAG_CONTROL_NONGENERIC
844      - verification/hs94.1x64x5/ tests ALLOW_GENARR{2D,3D}_CONTROL
845    
846    checkpoint63q (2012/07/30)
847    o pkg/autodiff:
848      note about monitor and snap-shot of ad-variables:
849      a) need to apply ADEXCH before monitor or output of ad-vars to include
850       overlap contributions (was done for adjDump but missing for monitor).
851      b) since ADEXCH implies adding overlap values to interior array, machine
852       truncation error is expected when adding an ADEXCH call in the middle of
853       the time-stepping (although mathematically identical).
854      modifs:
855      - fix some incorrect type (RL/RS, UV/scalar) in ADEXCH calls and ad-vars
856        declaration (adEddyPsiX,adEddyPsiY in adcommon.h).
857      - add new run-time params (dumpAdVarExch & mon_AdVarExch) to select how  to
858        apply ADEXCH before monitor or snap-shot of ad-variables:
859           =0 : no ADEXCH ; =1 : do ADEXCH ; =2 : apply ADEXCH on a local copy.
860      - implement new method (copy+adexch) for snap-shot and monitor of main model
861        ad-vars (initially not used by default -> output unchanged).
862      - change default (set to 2) to use new method and update few output_adm.txt
863        with accurate ad-monitor (global_ocean.90x40x15, tutorial_global_oce_biogeo
864        and both tutorial_tracer_adjsens tests).
865      - switch 2 global_ocean.cs32x15 AD-tests to AB-2 (seaice_dynmix & thsice)
866        and turn off momDissip_In_AB in the 2 other (needed for stable AB-3).
867    o pkg/ctrl:
868      enable the use of a variable number (maxCtrlArr2D, maxCtrlArr3D) of
869      generic control variables via
870      #define ALLOW_GENARR2D_CONTROL and/or #define ALLOW_GENARR3D_CONTROL
871      Only required customization should be S/R ctrl_map_ini_genarr.F
872      (routine in repository contains example)
873    o pkg/exf:
874      - fix and refine checking of surface-relaxation setting when using EXF
875    o verification (adjoint exp):
876      - reduce length of simulation by half for experiment global_ocean.cs32x15
877        (std, seaice & seaice_dynmix) and exp tutorial_dic_adjoffline; update output.
878    o pkg/mom_common (mom_u/v_bottomdrag), pkg/shelfice (shelfice_u/v_drag)
879      - replace if statements KE.ne.0 with KE.gt.0 to avoid sqrt of negative numbers
880        of KE that can occur with aggressive optimization
881      + put quadratic bottom drag calculation in separated loops (only done if
882        using bottomDragQuadratic)
883    o model/src: CG2D_NSA
884      - clean-up:  stop if cg2dNormaliseRHS=T and AUTODIFF
885         and replace GLOBAL_SUM calls with GLOBAL_SUM_TILE.
886      - in test-exp that uses CG2D_NSA (bottom_ctrl & tutorial_tracer_adjsens),
887         change cg2d residual target to be expressed in Wunits (=> do not normalise
888         RHS ; this fix global_max Pb with TAF); update output.
889    o verification/tutorial_tracer_adjsens:
890       improve parameter consistency (and get rid of warnings):
891       - use deltaTFreeSurf=deltaTtracer (better with NonLin FreeSurf);
892       - switch Temp Adv Scheme from 81 to 80 (no limiter since theta < 0 is physical)
893       - use staggerTimeStep (for stability) in som81; use default rotation period.
894    o pkg/exch2:
895      - with empty facet: fix compact-format (W2_mapIO=1) definition (was previously
896        reset to 0 = 1 long line in X)
897    o pkg/mdsio:
898      - fix reading of dimensions from meta file for large-size domain
899    o model/src:
900      - fix saltIsActiveTr setting for IdealGas eosType (eosType is 6 character long);
901      - to refine CS-grid check, add logical flag "hasWetCSCorners": true if using
902        Cubed-Sphere Exch with CS-corners inside the domain;
903        make new S/R INI_GLOBAL_DOMAIN from code in ini_linear_phisurf.F to calculate
904        globalArea and to set hasWetCSCorners.
905      - add warning if usingCurvilinearGrid and momAdvection in flux-form (missing
906        metric terms); stop if hasWetCSCorners=T and momAdvection in flux-form.
907      - re-activate the stop if useCDscheme and hasWetCSCorners=T (previously if
908        useCDscheme and useCubedSphereExchange).
909    o pkg/seaice/seaice_growth.F :
910      - compute the SEAICE_DISABLE_HEATCONSFIX term accordingly
911        for the (.NOT.useRealFreshWaterFlux).OR.(nonlinFreeSurf.EQ.0)
912        when the previous code was not correct.
913      - in all cases diagnoze the boundary condition mismatch to SIaaflux
914      - in the case of useRealFreshWaterFlux.AND.(nonlinFreeSurf.GT.0) add
915        that term to QNET (essentially to set the melt/freeze water to 0degC).
916        when SEAICEheatConsFix is true, so that the ocean+ice budget heat is closed.
917    o verification/global_ocean.cs32x15/input.seaice :
918      - add SEAICEheatConsFix in data.seaice, ensuring closed ocean+ice heat budget.
919      - add diagnostics (commented out) for budget test using my matlab codes (gcmfaces).
920      - update results (output.seaice.txt) accordingly.
921    o verification/lab_sea/input/data.seaice :
922      - remove SEAICEheatConsFix, which is now be tested
923        in global_ocean.cs32x15. The presently coded fix
924        is only consistent with real fresh water + nlfs.
925      - update results (output.txt) accordingly.
926    o pkg/salt_plume: added diagnotic for salt tendency (oceSPtnd).
927    o AD_CONFIG.h file:
928      - in genmake2: remove "#undef ALLOW_ECCO_OPTIMIZATION" from AD_CONFIG.h;
929      - remove #include "AD_CONFIG.h" from all included OPTIONS files and
930        add it explicitly in each fortran src file where it is needed.
931        motivation: header file AD_CONFIG.h is generated/modified after "make depend"
932        thus introducing potentially wrong dependency; therefore, better to include
933        it only where it's really needed, and after any other included OPTIONS file
934        (less tempting to bring conditional includes according to ALLOW_ADJOINT_RUN
935        or ALLOW_TANGENTLINEAR_RUN).
936    
937    checkpoint63p (2012/07/06)
938    o pkg/autodiff:
939      - rename S/R INI_AUTODIFF to AUTODIFF_INIT_VARIA ;
940      - create new header file "AUTODIFF_PARAMS.h" for pkg/autodiff parameters
941        which are now read from new parameter file "data.autodiff" (inAdExact
942        previously in "data", use{KPP/GMRedi/SEAICE}inAdMode previously in data.pkg)
943      - add file "data.autodiff" in all verification/*/input_ad/ directories.
944      - add run-time parameter to turn On/Off SEAICEuseFREEDRIFT in adjoint/forward
945        mode (used in global_ocean.cs32x15.seaice_dynmix test exp.)
946    o verification/tutorial_tracer_adjsens/
947      - add extra sub-verification which uses "SOM" advection scheme
948        (2nd Order-Moment Advection Scheme, Prather Limiter) with
949          #define GAD_ALLOW_TS_SOM_ADV in GAD_OPTIONS.h
950        and in data:
951          multiDimAdvection=.TRUE.,
952          tempAdvScheme=81,
953          saltAdvScheme=81,
954    o model/src:
955      - introduce ALLOW_BALANCE_RELAX which allow the removal
956       of the global mean of relaxation terms by setting
957       balanceThetaClimRelax and balanceSaltClimRelax
958      - disable balanceEmPmR and balanceQnet in the case when useSeaice.
959       This case is now treated appropriately in seaice_growth.F
960    o pkg/seaice:
961      - do balanceEmPmR and balanceQnet based on the net fluxes
962        (SItflux) that enter the ocean+ice system rather than QNET
963        and EMPMR. Works best in real fresh water.
964      - SIatmFW, SIatmQnet, and SItflux computations had to be moved
965        out of the diagnotics bloc, and stored in global arrays.
966    
967    checkpoint63o (2012/06/29)
968    o vertical mixing schemes:
969      - remove unused S/R CALC_BUOYANCY (left from branch-atmos merging)
970      - replace computation of density (in Function STATE1, opps_calc.F) by a call
971        to S/R FIND_RHO_SCALAR
972      - pass sigmaR to S/R PP81_CALC, MY82_CALC (but not yet used) and to GGL90_CALC
973        and use it for N^2 calculation in ggl90_calc.F (save 2 density computations);
974        affects output (vermix.ggl90) at truncation level.
975    o testreport:
976      - change adjustment of SIZE.h for mpi+mth testing: preserve enough tiles
977        (nSx,nSy) for the number of threads (from eedata.mth)
978    o model/src:
979      - remove 2nd set of calls at the top of initialise_varia.F (Adjoint part)
980        related to Non_Lin Free-Surf or Bottom-Control (but not longer necessary).
981  o verification/tutorial_tracer_adjsens/  o verification/tutorial_tracer_adjsens/
982    - compile with ALLOW_CG2D_NSA    - compile with ALLOW_CG2D_NSA
983    - run with nonlinFreeSurf=3    - run with nonlinFreeSurf=3
