5      ==============================      ==============================
6    
7    o pkg/obcs: modify Stevens boundary conditions so that S/R obcs_calc_stevens
8      computes tendency for temperature and salinity that is then applied to update
9      theta and salt in S/R obcs_apply_ts; this requires proper masking of all
10      horizontal advection and diffusion contributions on the boundary (in
11      S/Rs gad_advection, gad_calc_rhs, gmredi_rtransport, gmredi_calc_diff), and
12      removing the mask in S/R timestep_tracer. The advantage of this approach is
13      that the updated tracer values include contributions from the surface
14      forcing and vertical diffusion.
15      This modification changes exp4.stevens because of vertical diffusion.
16    o model/src:
17      change non-curvilinear grid setting to also work with exch2 + blank tiles:
18      - move delX,delY to new header file (SET_GRID.h) and adjust length to 1rst
19        face dimensions.
20      - new S/R INI_LOCAL_GRID to define model tile-local grid (using same units
21        as delX,delY) and called from S/R INI_CARTESIAN_GRID, INI_CYLINDER_GRID
22        and INI_SPHERICAL_POLAR_GRID.
23      change test-experiment global_ocean.90x40x15:
24      - split the domain in many more tiles (9x4 tiles of 10x10 each);
25      - switch to exch2 and remove 1 blank-tile (but only for MPI test).
26      - update results of both test (std & dwnslp).
27    o pkg/diagnostics/diagstat_calc.F: fix problem with non-initialised halos in
28       tmp-fields for TARGET_NEC_SX at the cost of extra loops and less vectorisation
29    o model/src:
30      - take sigma-coords related code out of update_etah.F into new S/R UPDATE_ETAWS
31        and fix initialisation when using sigma-coords.
32    o model/src:
33     - improve Gael's changes from Jan 14, 2011 "addition of an 'update' of hfacc etc.
34       to their current value at the beginning of forward_step.F": add a new run-time
35       switch "doResetHFactors" (default=false) and use it to do (or not) the resetting.
36     - set doResetHFactors=T in the following test exp:
37        global_ocean.90x40x15/input (rStar) & input.dwnslp (linFS),
38        global_ocean.cs32x15/input.seaice (rStar), hs94.cs-32x32x5/input.impIGW (linFS)
39        and tutorial_global_oce_in_p (nonLinFS in p)
40    o pkg/ecco
41      - added IES cost term
42    o verification/advect_xz
43      - scale down the depth by 1/100 (from 200 km to just 2.km)
44      - add secondary test using divergent flow, r-star and implicit vertical advection.
45      - add note (check_conserve_TS.txt) and matlab script to check global
46        conservation of T & S with NonLin-FreeSurf and Adams-Bashforth.
47    o pkg/rbcs:
48      - add missing relaxUFile & relaxVFile in namelist (in rbcs_readparms.F).
49    o pkg/obcs (Stevens BCs):
50      - fix various problems in the phase speed computations of the Stevens
51        boundary conditions:
52        - sign error for western and southern boundaries,
53        - time tendencies were underestimated by factor of dTracerLev and some just
54          zero (for multidim advection schemes) -> now estimate time tendencies
55          from difference between previous (n) time level and the one before (n-1);
56          this requires storing a field per tracer per boundary, also in the pickup
57          files.
58        - replace deltaTmom in cflMer/Zon computation with dTracerLev
59        - set default phase velocity to cflMer/Zon
60      - update verification experiment exp4.stevens
61    o pkg/generic_advdiff (implicit_r):
62      - fix implicit vertical advection conservation with AB and/or NonLin-FreeSurf
63        (remove Tr*d/dz(w) in gad_implicit_r.F and add it in gad_calc_rhs.F);
64      - fix implicit vertical diffusion or advection with NonLin FreeSurf
65        (was using current recip_hFacC instead of future recip_hFacC): set future
66        recip_hFac in thermodynamics.F and pass & use it in all vertical implicit
67        solver S/R ;
68      - fill diagnostics of vertical advective fluxes (computed from tendency)
69        when using implicit vert. advection;
70      - update output of exp that uses NonLin-FreeSurf & implicit vertical diffusion:
71         global_ocean.90x40x15 (fwd+AD), global_ocean.cs32x15 (4 fwd +4 AD),
72         tutorial_global_oce_in_p (fwd), tutorial_tracer_adjsens (AD)
73         and cpl_aim+ocn (used in ocean); to be fixed: bottom_ctrl_5x5.
74    o pkg/diagnostics:
75      - add diags for T & S tendency which goes through Adams-Bashforth.
76    
77    checkpoint63f (2011/11/30)
78    o pkg/obcs/obcs_calc_stevens.F:
79      - join some loops to reduce number of if-statements
80      - fix a bug in code for northern and southern boundaries.
81    o pkg/seaice/seaice_init_varia.F
82      - undo resetting UVM=0 that has slipped in unnoticed in r1.49 and
83        caused zero ice-velocities for the B-grid code
84    o pkg/seaice/seaice_init_fixed.F
85      - fix a bug in the initialisation of the second metric terms
86        k2AtC and k2AtZ: k2AtC was set to the value of k2AtZ and k2AtZ was 0.
87      - this affects all seaice configurations with useCurviLinearGrid = .true.
88        and SEAICEuseDynamics = .true. (default) and SEAICEuseMetricTerms
89        = .true. (default)
90      - the only verification experiment affected is global_ocean.cs32x15:
91        icedyn, seaice, and seaice_dynmix (AD)
92    o pkg/thsice/thsice_diagnostics_state.F
93      - only for TARGET_NEC_SX: initialise all of tmpFld, so that overlap does
94        not contain garbage that can lead to surprises in diagstats_calc.F
95    o model/src:
96      - move bi,bj loops inside INTEGR_CONTINUITY ;
97      - call INTEGR_CONTINUITY directly from forward_step.F
98        (previously called from momentum_correction_step.F)
99      - call UPDATE_ETAH from integr_continuity.F and update initialise_varia.F,
100        forward_step.F and pkg/ecco/the_main_loop.F
101    o model/src/do_oceanic_phys.F:
102      - reset addMass to zero only if useICEFRONT ;
103      - separated k-loop for rhoInSitu calculation ;
104      - add 2 diagnostics for wVel*delta^k(Rho) at constant pressure (= WdRHO_P)
105        and at constant T,S (= WdRHOdP);
106      NOTE: change diagnostics WRHOMASS : this is now simply the Vertical transport
107        of In-Situ Density (Anomaly) (=wVel*rho^bar-k) (previously was Vertical
108        transport of locally-referenced potential density);
109        to recover old diag: (WRHOMASS)_old = (WRHOMASS)_new -1/2 * (WdRHOdP)
110    o gluemnc:
111      - replace ncrcat with ncks when adding variables to *.glob.nc
112      - change the way variables without record dimensions are handled so that
113        files that have variables with and without record variables can be glued:
114        add a record dimension with a new unique name to be able to differentiate
115        between variable with and without a-prior record dimensions. Remove
116        this record dimension before adding the variable to the *.glob.nc file.
117        This procedure automatically works also for grid.*.nc files that do not
118        have any record dimension.
119    o verification/cpl_aim+ocn:
120      - generate new reference output on baudelaire (gfortran, mpich2) (previously
121        from old aces-grid cluster, ao + ifort) and update 'run_cpl_test' script.
122    o pkg/obcs/obcs_calc_stevens.F:
123      - add code for northern and southern boundaries.
124      - reorder some loops to save some operations and so that drFBar can be scalar
125    o model/src:
126      - re-arrange extrapolation calculation in Adams-Bashforth S/R (affects machine
127        truncation) and add diagnostics for Adams-Bashforth tendency increment.
128      - update test-exp. AD output:
129        1D_ocean_ice_column, bottom_ctrl_5x5, lab_sea.noseaicedyn, obcs_ctrl;
130      and FWD output: exp4 (x3), fizhi-cs-32x32x40, fizhi-cs-aqualev20,
131        front_relax (x3), global_ocean.90x40x15 (x2), global_ocean.cs32x15 (x5),
132        global_ocean_ebm, ideal_2D_oce, internal_wave, isomip (x3), lab_sea (x4),
133        matrix_example, MLAdjust (x5), natl_box (x2), tutorial_advection_in_gyre,
134        tutorial_global_oce_in_p, tutorial_global_oce_latlon and
135        tutorial_plume_on_slope.
136    o pkg/diagnostics/diagstats_calc.F: add special code for TARGET_NEC_SX
137      that vectorises. This code uses 3 extra 2D fields, F90 array assignments
138      and F90 intrinsic routines SUM, MINVAL, MAXVAL, but since TARGET_NEC_SX
139      does not even come with an F77 compiler anymore, this should not be
140      a limitation
141    
142    checkpoint63e (2011/11/06)
143    o pkg/seaice adjoint of LSR:
144      - substantially rework STORE dirs.
145      - add new flag SEAICE_LSR_ADJOINT_ITER and parameter SOLV_MAX_FIXED
146        this flag will do SOLV_MAX_ITERS but only store SOLV_MAX_FIXED fields
147        and only perform SOLV_MAX_FIXED adjoint iters.
148        If flag SEAICE_LSR_ADJOINT_ITER is undef-ined, the store in the iteration
149        always goes to same record, meaning that the last forward field will be
150        the one used in the adjoint - an approximation.
151      - now produces non-zero LSR-related gradients, and acceptable gradients for
152        An's zonal (x-z) test case (to be checked in)
153      - lab_sea: produces acceptable gradients for lab_sea with forward/backward LSR
154        (but these are screwed up by the thermodynamics in the first place);
155        reduce from 4 to 3 timesteps to avoid t.d. issue as temporary solution;
156        output_adm.txt also reflects changes to seaice_lsr
157      - global_ocean.cs32x15:
158        * the "default" input_ad.seaice has been re-defined to always exclude dynamics
159          (output_adm.seaice.txt was updated)
160        * new input_ad.seaice_dynmix tests a forward LSR / backward free-drift
161          (output_adm.seaice_dynmix.txt)
162    o test-exp. exp4+stevens:
163      - switch off pTracers and nonHydrostatic (restart problems with NH); update output
164    o pkg/seaice (lsr solver):
165      - put coriolis term into FORCEX,Y (as in seaice_evp.F; previously in rhsU,V only);
166        update output (change truncation) of FWD test exp lab_sea & global_ocean.cs32x15
167      - fix SEAICEuseFREEDRIFT for new OBCS version (ndef OBCS_UVICE_OLD)
168      - new parameter "LSR_mixIniGuess" allows (if=2,4) to mix free-drift solution
169        into initial guess for linearised solver; use weight ~ (1/err)^2,4.
170      - compute (with new S/R) and print initial (+ free-driff sol. if available)
171        and final residual of linearised system.
172    o pkg/pp81: add diagnostics for vertical eddy viscosity and diffusivity
173      (requires new subroutines pp81_init_fixed.F/pp81_diagnostics_init.F)
174    o pkg/obcs: Stevens BCs (still only for east and west)
175      - fix Stevens BCs by using intermediate velocities of previous
176        time step as "baroclinic" contribution rather velocity of one grid cell
177        inside the boundaries; more consistent but makes the entire treatment
178        more complicated, requires new pickup files and two new S/Rs:
179        obcs_copy_uv_n and obcs_save_uv_n
180        keep old version with flag OBCS_STEVENS_USE_INTERIOR_VELOCITY
181        (undefined by default)
182      - silently move computation of some grid factors into separate loops to
183        save some recomputations
184      - add a hack for non-linear free surface
185      - add a verification experiment to exp4 that tests this code
186    o make gluemnc/xplodemnc work with (moron) non-GNU shell tools
187    
188    checkpoint63d (2011/10/25)
189    o pkg/obcs + seaice-dynamics:
190      - new implementation calls OBCS_APPLY_UVICE (in seaice_dynsolver.F) before
191        solving for uIce,vIce and prevent SEAICE_LSR or SEAICE_EVP to modify OB
192        values (consistent with an implicit method).
193      - add option OBCS_UVICE_OLD (in OBCS_OPTIONS.h, defined by default) to
194        return to older implementation (same results as before); note that none of
195        the "experimental" OBCS_SEAICE options are implemented in the new version.
196      - switch test exp. seaice_obcs to use new version (update output).
197    o pkg/seaice:
198      - add few stop (B-grid & CS-exch, B-grid & obcs, AUTODIFF & SEAICE_maskRHS)
199      - add parenthesis in Water-Ice drag calculations (evp & lsr);
200      - in seaice_lsr.F, simplify and fix AA3 setting in case sNx or sNy=1;
201        and fix case SEAICE_waterDrag=0 (but unstable if no or little seaice)
202      - update output of test exp lab_sea that uses evp or lsr (fwd+ad)
203        and global_ocean.cs32x15 (icedyn & seaice fwd+ad).
204    o pkg/layers:
205      - Include potential density as new coordinate (Thanks to David Munday)
206    o pkg/dic:
207      - Remove subroutine CALC_PCO2_APPROX_CO3 from carbon_chem.F and add
208        carbonate computation/output to CALC_PCO2_APPROX
209    o pkg/generic_advdiff
210      - make TAF generate code that vectorizes:
211        gad_dst3fl_adv_*.F, gad_u3c4_impl_r.F
212    o model/src:
213      - improve vectorization also for adjoint code of
214        solve_tridiagonal and solve_pentadiagonal. As this requires up to
215        5 new 3D-fields, this code is only turned on for the combination of
216        ALLOW_AUTODIFF_TAMC and TARGET_NEC_SX. Also remove error message
217        for singular matrix check (only for TARGET_NEC_SX).
218      - remove hard-wiring of CPP-flag ALLOW_SOLVERS_KLOOPINSIDE to
219        ALLOW_AUTODIFF. This flag now needs to be set outside of
220        solve_tri/pentadiagonal.F
221    o pkg/exf:
222      - fix previous modif in exf_readparms.F (revision 1.66: treatment of
223        optional namelist EXF_NML_OBCS).
224      - add many debug-print (to trace down where pkg/cal error msg comes from)
225    o pkg/mom_vecinv/mom_vi_hdissip.F
226      - rearrange loops so that vectorization is improved and in particular
227        the adjoint routine vectorizes. The code is a little longer now, but I
228        think easier to read.
229        Note: CPP-flag MOM_VI_ORIGINAL_VISCA4 is not tested.
230    o pkg/seaice:
231      - allow to specify initial seaice velocity from files (uIceFile,vIceFile)
232    o pkg/exch2:
233      - alternative code (without tile x tile matrix) for cumulated (global) sum;
234        used as default; keep using matrix version in adjustment.cs-32x32x1.
235    o tools/build_options:
236      - after merging some MPI and/or multi-threads specific optfiles so that
237        the modified default optfile support both built (using genmake2 -mpi
238        for the MPI built, using genmake2 -omp for OpenMP built),
239        move now obsolete optfiles to tools/build_options/unsupported/
240       (add copy of email sent to support list in doc/optfiles_changes.txt)
241    
242    checkpoint63c (2011/09/28)
243    o pkg/ebm:
244      - fix ebm_zonalmean.F for several procs in Ydir (nPy > 1); update output of
245        test exp. global_ocean_ebm (affects machine truncation, 12 digits for cg2d)
246    o pkg/seaice (SItracer pickup)
247    * Simple code for pickup of SItracer fields (#define ALLOW_SITRACER)
248      To be done:
249      - thorough testing of missing fields in S/R seaice_read_pickup
250      - thorough matching between generic tracers and specific fields used
251        (e.g. volume-weighted age, area-weighted age, salinity, ...)
252    o pkg/grdchk:
253      - all procs calculate and print finite-difference gradient (for testreport)
254      - change description output used by testreport;
255      - AD testing: also compare and report Finite-difference gradient;
256        => update all output_adm*.txt
257    o test exp. global_ocean_ebm:
258      - switch back useRealFreshWaterFlux (no problem anymore with run-off);
259        and turn on exactConserve; update (fwd) output.
260    o pkg/seaice (LSR):
261      - print to STDOUT number of solver iterations at SEAICE_monFreq interval.
262      - modify solver to deal cleanly with u/v switch at face edges (CS-grid):
263        * identical results with non-CS topology (but save up to half of EXCH calls)
264        * no much changes in cs-32 verification tests since no ice at face edges
265         (differences due to convergence criteria, since nb of iterations changed)
266        * expect some differences on lat-lon-cap grid.
267        update FWD results of global_ocean.cs32x15 test exp. (icedyn & seaice)
268    o pkg/exch2:
269      - add new CPP option to disable Cumul-Sum matrix (to save storage when using
270        many tiles); until alternative coding is added, just add a stop.
271    o pkg/kpp:
272      - move ptracer/salt correction to KPP diffusivity from calc_3d_diffusivity.F
273        to S/R KPP_CALC_DIFF_PTR (+ add tracer-index to argument list).
274    o optfiles:
275      - merged few MPI specific (*+mpi*) and multi-threads specific (*+mth) optfiles
276        into corresponding standard one, which now support different build:
277        (when using "genmake2 -mpi" for MPI built, "genmake2 -omp" for OpenMP built)
278      - add "darwin_amd64_gfortran" optfile (initially from Constantinos, tested by Gael)
279    o pkg/obcs (seaice):
280      - add missing EXCH for uIce,vIce after applying OBCS;
281      - remove S/R EXF_SWAPFFIELDS_X/Y , disable S/R EXF_SET_OBCS_X/Y by adding
282        argument = number of levels to S/R EXF_SWAPFFIELDS_XZ/YZ and S/R
283        EXF_SET_OBCS_XZ/YZ ; update obcs_exf_load.F;
284      - fix EXF_SET_OBCS_XZ/YZ for multi-threaded (assuming loaded arrays are shared)
285      - verification exp. seaice_obcs: split domain in 2 tiles ; add SIZE.h_mpi
286        and eedata.mth for MPI and mutlti-threaded testing.
287    o pkg/flt:
288      - make FLT EXCH working with multi-threads (and MPI + multi-threads);
289      - use buffer for floats IO (trajectories & profiles); size set in FLT_SIZE.h;
290      - fix pickup and trajectories + profiles output with multi-threads;
291      - add parameter to select group of fields to write along trajectory and
292        profile (default unchanged);
293      - only call PORT_RAND* function when flt_noise <> 0;
294      - add multi-threaded test for verification exp. flt_example.
295    o eesupp/src:
296      - fix S/R ALL_PROC_DIE for MPI+multi-threads.
297      - USE_OMP_THREADING: check that number of threads (from eedata) matches
298        actual number (from env.var. setting).
299    o pkg/ebm:
300      - fix multi-threading in ebm_area_t.F ; clean-up EBM.h header file.
301      - add multi-threaded test for verification exp. global_ocean_ebm
302    
303    checkpoint63b (2011/08/29)
304    o pkg/ebm:
305      - fix sign of runoff;
306      - update directly forcing fields (Qnet,EmPmR) to use standard
307        external_forcing_surf.F (remove ebm_forcing_surf.F);
308      - avoid loading forcing fields a 2nd time (1rst time from ini_forcing.F);
309      - set either tauThetaClimRelax (in data) or tauThetaZonRelax (in data.ebm)
310        and apply relaxation towards corresponding SST field (2-D map or ZonAver).
311      - update global_ocean_ebm parameters file data and update output (fwd+ad).
312    o verification/matrix_example:
313      - split domain in 8 tiles (2x4); add SIZE.h_mpi and eedata.mth for
314        MPI and mutlti-threaded testing.
315    o pkg/matrix:
316      - change name of S/R MATRIX_INIT to S/R MATRIX_INIT_VARIA ;
317      - fix for multi-tiles (add bi,bj indices to exp/impMatrixCounter);
318      - fix for multi-threaded (remove DATA statement);
319      - use standard DIFFERENT_MULTIPLE function;
320      - add MATRIX_OPTIONS.h
321    o verification/matrix_example:
322       To allow to split the domain in several tiles, change the domain size
323        from 31x31 to 32x32 by adding 1 row (on Southern side) + 1 column (on
324        Western side) of land points.
325    o (*_)write_pickup:
326      - fix few bugs in mypackage_read/write_pickup.F
327      - in MDS_WR_METAFILES calls, replace "myTime" by a local copy into
328        array of length 1 (was caught by compiler syntax-check).
329    o pkg/diagnostics (velocity potential solver):
330      - fix initialisation of main diagonal matrix (for overlap values)
331    o tools/build_options:
332      - towards single optfile for MPI and non-MPI built: merge few +mpi optfile
333        into previously non MPI one (linux_am64 pgf77,open64,pathf90,ifort11)
334      - linux_amd64_gfortran: merge +mpi_generic version into standard optfile:
335        * move IEEE flags to DEVEL section; take IEEE flags from +mpi_generic ;
336        * FAST case: for now, keep -O3 with ini_masks_etc.F in NOOPTFILES list;
337        and use "-devel" testreport option for standard testing on baudelaire.
338    o pkg/grdchk:
339      - Assume that all gradient-check position are within the same tile
340        corresponding to global indices (iGloTile,jGloTile) and that
341        positions (i,j indices or nbeg) are local to this tile;
342      - set tile local-indices and proc. number according to tile global-indices;
343      - remove grdchkwhichproc from namelist (retired param);
344      - send adjoint gradient to all procs so that all procs print it to STDOUT;
345      - switch on MPI test for global_ocean.90x40x15 AD test experiment.
346    o adding package bbl (Bottom Boundary Layer)
347      description in MITgcm/pkg/bbl/bbl_description.tex
348      example/test experiment in MITgcm_contrib/bbl
349    o adjoint verifications
350      - changed 5 experiments to multi-tiles
351        * global_ocean.90x40x15
352        * obcs_ctrl
353        * offline_exf_seaice
354        * tutorial_dic_adjoffline
355        * tutorial_tracer_adjsens
356        changed reference output for those that crossed tile boundaries
357        (changed choices of gradient check positions)
358      - with same tiling, switch on MPI test for the last 4 (add SIZE.h_mpi)
359      - temporary bug fix in grdchk_loc.F for obcs
360    o genmake2 & testreport
361      - add target "obj" (just for OBJFILES files) to Makefile;
362      - add option to specify FEXTRAFLAGS on command line.
363    o pkg/mypackage:
364      - remove bi,bj arguments from argument list of S/R MYPACKAGE_CALC_RHS
365    
366    checkpoint63a (2011/08/02)
367    o pkg/diagnostics (velocity potential):
368      - fix velocity-potential calculation when using OBCS: balance net inflow
369        at each level (new S/R OBCS_DIAG_BALANCE).
370      - fix some of the problems with OBCS in stream-function calculation.
371    o pkg/exf/exf_readparms.F
372      - make treatment of optional namelists (EXF_NML_04, EXF_NML_SGRUNOFF,
373        EXF_NML_OBCS) more consistent, so that you need not have these lists
374        in data.exf when they are not used.
375    o optim/optim_readdata.F:
376      - add some output about obcs variables that might help debugging
377      - add a check about nvarlength
378    o pkg/ctrl: once again, fix computation of endrec in s/r ctrl_init_rec
379    o pkg/diagnostics (velocity potential):
380      - fix mask for OBCS (still problems in stream-function with OBCS);
381      - add specific parameter (default = main code CG2D params) for solver;
382      - in case of poor convergence, use solution corresponding to lowest residual.
383    o pkg/seaice/seaice_growth.F: small changes that permit vectorizable
384      adjoint code. In general statements like tmpscal=fld(i,j) are problematic
385      and should be avoided where possible.
386    o model/src (rStar):
387      - include r* effect on reference-state (PhiRef) in totPhiHyd
388        (so that it's really the potential anomaly at the cell center);
389        affect solution only if z* with full pressure in EOS.
390      - test-exp global_ocean.90x40x15: reduce viscA4 (was not stable) and
391        update output (because of z* in totPhiHyd and viscA4 changes);
392      - keep the previous diagnostics as "PHIHYDcR" (closer to potential anomaly
393        @ constant r) until interpolation at constant r is implemented.
394    o pkg/diagnostics
395      - fix RCENTER diagnostics in case cell center is not at interface middle
396    o add code for TEOS-10 (www.teos-10.org, McDougall et al. 2011). Use
397      this eos with eosType = 'TEOS10', in data (PARM01). This eos implies
398      that THETA and SALT are "conservative temperature" and "absolute
399      salinity"
400    o pkg/ctrl
401      - fix computation of endrec in s/r ctrl_init_rec
402      - ctrl_pack/unpack_*: remove unused variables and some obsolete code
403    o pkg/seaice/seaice_growth.F
404      - fix recomputation with FENTY_AREA_EXPANSION_CONTRACTION code,
405        remove then obsolete STORE directives
406      - fix STORE directives for tice and tices, so that only the
407        appropriate part of the fields are stored (and not the entire
408        field); update global_ocean.cs32x15.seaice AD output.
409      - cosmetic changes: adjust CPP flags and indentation for better
410        legibilty
411    o pkg/autodiff: add mnc-output of adBottomDragFld (code contributed by
412      Chris Wilson)
413    o pkg/gmredi:
414       Add Sub-Meso Eddies parameterisation from Baylor (for now, disabled with TAF),
415       and test it in verification exp. "front_relax.bvp" (update output.bvp.txt)
416    
417    checkpoint63  (2011/07/11)
418    o pkg/exch2:
419     - rename+move: nTiles in W2_EXCH2_PARAMS.h --> exch2_nTiles in W2_EXCH2_TOPOLOGY.h
420     - exch2 version of Cumul-Sum routine: S/R W2_SET_MAP_CUMSUM set up the
421       (2*nTiles)x(nTiles) Cumul-Sum matrix and Master Proc collects all tiles X,Y
422       increments, calculates Cumul-Sum @ tile origin and sends results to each tile.
423    o pkg/diagnostics:
424     - deal with pairs of post-processed diags which are computed together; in
425       particular, re-order list of diags within 1 file to save 2nd computation.
426     - add S/R to compute velocity stream-function (called after velocity-potential
427       calculation) from divergence free transport -> new diagnostics "PsiVEL".
428     - add parameter to select grid-point location where PsiVEL == 0.
429    o eesupp/src:
430       new S/R to calculate cumulated sum on tiled array, corner grid-cell location
431       (specific S/R needed with exch2 topology - for now, just print an error msg)
432    o pkg/shelfice
433     - Implement friction velocity-dependent transfer coefficients following
434       Holland and Jenkins, JPO, 1999
435       Original code by M. Losch with small modifs.
436       Enable with CPP option SHI_ALLOW_GAMMAFRICT
437       and runtime flag SHELFICEuseGammaFrict
438    o verification lab_sea & global_ocean.cs32x15:
439     - use tools/xmakedepend (instead of cyrus_makedepend, in genmake_local):
440       does not miss some dependencies (but is slower) and also works with many files
441       (default makedepend limitation for AD built).
442     - use cyrus_makedepend in adjustment.128x64x1 (so that it still tested).
443    o pkg/diagnostics:
444     - add run-time parameter "useMissingValue" (def=False) to fill land-point
445        (i.e., where mask=0) with MissingValue ; used only in MNC output file.
446       This replaces CPP-option DIAGNOSTICS_MISSING_VALUE.
447     - Extend the use of "missing_value" setting from data.diagnostics for the case
448       of counter-diagnostics (where fraction-weight is zero). This applies both to
449       MNC and MDS output files.
450    o pkg/seaice/seaice_growth.F:
451      - add 'a priori' cap of latent heat flux based on actual mass considerations
452        when SEAICE_ADD_SUBLIMATION_TO_FWBUDGET is used in conjunction with the
453        non-legacy seaice_solve4temp.
454      - add diagnostic of the residual sublimation freshwater flux (the freshwater
455        flux taken from the ocean if the total actual latent heat fluxes exceed
456        the maximum)
457      - remove the CPP switch around the *_FWbySublim unit change and move diagnostic
458       fill for SIatmQnt, SIfwSubl, SIatmFW to the end of seaice_growth.F.
459      - add diagnostic of the actual sublimation freshwater flux (that is 0. ifndef
460       SEAICE_ADD_SUBLIMATION_TO_FWBUDGET) and of the latent heat flux (evap+sublim).
461      - bug fix : frWtrAtm needs a_FWbySublim ifdef SEAICE_ADD_SUBLIMATION_TO_FWBUDGET.
462      - bug fix : missing part to Martin's r_FWbySublim pathological case fix.
463    o verification 1D_ocean_ice_column:
464       made model domain truly 1x1x23 instead of 5x5x23 with only center cell (3,3,:) wet
465       update results
466    o pkg/diagnostics:
467     - Implement setting of "Post-Processed" diagnostics (corresponding to gdiag(5)='P')
468       which are not filled-up but computed from other diags ; In this case, the mate
469       diag points to the primary (filled-up) diag to used for post processing.
470     - Update Velocity-potential computation using post-processed diag framework.
471     ==> Change the ordering of fields and time-periods in MDS output file
472       when using periodic averaging: now writes one time record with the full set
473       of fields for this time period, then the next time reccord (it used to be
474       one field with the full set of time records then the next field).
475         Note: this is now similar to NetCDF (MNC) output file. <==
476    
477    checkpoint62z (2011/06/21)
478    o adjoint monitor:
479     - Add adjoint monitor output for packages exf, seaice
480       and update relevant testreport output
481    o pkg/seaice:
482     - re-order diags inits so that they appear in order in available_diagnostics.log
483     - added diags: hsnow thermo. rates of change, area preceeding ridiging process,
484       area/heff/hsnow preceeding thermodynamic growth/melt.
485     - modified diag: SIdA; output actual effect, as the description states.
486     - modified description: SIqneti, SIqneto, SIuheff, SIvheff, SIdAb*, HSNOW.
487     - retired redundant diags: SIyneg, SIfice, SIsnwice, SIthdgrh.
488       (SIyneg->SIdHbOCN; SIfice->SIdHbATC; SIsnwice->SIdHbFLO;
489        and SIthdgrh->SIdHbOCN+SIdHbATC+SIdHbATO)
490     - modified diags (2) : switch all SIdA*, SIdH*, SIdS* from delta to rates.
491     - added diagnostics for seaice generic tracers (SItr*).
492     - added SItrUnit and SItrNameLong run time param (for SItr* diags).
493     - in diag names, replaced 'PrTh' abbrev. of 'preceeding thermo' with 'PT'.
494     I. Fenty: 18-Jun-2011:
495     Minor changes to seaice package:
496     1) Retired old variables (A22, SEAICE_lhsublim, areaMax, areaMin, hiceMin) and
497        added some new ones (SEAICE_area_reg, SEAICE_hice_reg, SEAICE_area_floor)
498       - Differentiated "regularization variables" from "floor variables"
499        * areaMin became SEAICE_area_reg (old A22) and SEAICE_area_floor
500        * hiceMin became SEAICE_hice_reg (old hiceMin)
501          (with _reg meaning regularization variable)
502       - SEAICE_lhSublim becomes lhSublim, the sum of SEAICE_lhEvap and SEAICE_lhFusion
503        so as to ensure energy conservation when going between phases
504      - A22 was not used anywhere
505     2) Changed regularization procedure for heffActual and hsnowActual to ensure
506        well-boundedness and smooth adjoint in seaice_growth.F
507     3) Fixed a bug where seaice_solve4temp would not recognize ice-free grid cells
508        because the old regularization always set heffActual >= 0.05 cm
509     4) Changed the model so that the default behavior is to put a small (10^-5) "floor"
510        on AREA when HEFF > 0.
511      - went from requiring ALLOW_PRECLUDE_INFINITESIMAL_AREA to be defined to
512        requiring that DISABLE_AREA_FLOOR *not* be defined
513     Affected verifications:
514      - 1D_ocean_ice_column (output.txt output_adm.txt)
515      - global_ocean.cs32x15 (output.seaice.txt output_adm.seaice.txt)
516    o pkg/diagnostics:
517      - move MNC code from diagnostics_out.F into new diagnostics_mnc_out.F (2 S/R).
518      - rename S/R GETDIAG to DIAGNOSTICS_GET_DIAG and change type of 1rst argument
519        (was _RL, now integer) with option = 0 to retrieve all levels.
520      - add pieces of code to compute velocity potential at each level (new diagnostics
521        PhiVEL, works only when UVELMASS & VVELMASS are also turned on);
522        for now, using same params as CG2D (target-resisual, max Nb of iter ...).
523      - fix few issues with counter diagnostics in diagnostics_setdiag.F &
524        diagstats_setdiag.F (if diagnostic counter is itself a counter diag)
525        and in diagnostics_fract_fill.F (do not need a valid pointer for the
526        diagnostics counter-mate); check that definition of counter-diagnostic
527        includes a valid counter-mate (in diagnostics_set_levels.F).
528    o model/src (rStar):
529      - add rStar scaling factor in diags_phi_hyd.F (similar to calc_grad_phi_hyd.F);
530        affect solution only if z* with full pressure in EOS;
531        update output of test-exp global_ocean.90x40x15.
532    o pkg/seaice:
533      - introduce siEps=1e-5 parameter
534      - use areaMax in AREA update (part 4), consistent with ridging step (part 2.5).
535      - re-organize SEAICE_ADD_SUBLIMATION_TO_FWBUDGET code.
536      - introduce ALLOW_SITRACER and seaice_tracer_phys.F to handle generic seaice tracer.
537        For now it covers, and was tested for, ice salinity and age (attached to HEFF),
538        as well as ice cover age and ridging index (attached to AREA).
539        For now the run time parameters (in data.seaice/SEAICE_PARM03) are
540        SItrName (e.g. 'age') and SItrMate ('HEFF', which is the default, or 'AREA').
541        Up to SItrMaxNum=3 tracers can be used simultaneously.
542    o pkg/salt_plume:
543      -introduce SPsalFRAC run time parameter that sets the fraction of the
544       salt by-product of ice growth (SPsalFRAC*(1-SIsalFRAC)*salt typically)
545       that gets vertically redistributed (fluxed down) by pkg/salt_plume.
546    o model debug options:
547      - Switch reading of debugMode from S/R INI_PARMS (parameter file "data", stored
548        in PARAMS.h) to S/R EESET_PARMS (parameter file "eedata", stored in EEPARAMS.h).
549      - Refine debug-msg printing selection (3 new levels):
550        debugMode  : controls printing of debug messages (sequence of S/R calls).
551        debugLevel : controls printing of algorithm-relevant auxiliary/debug messages
552         debLevZero =  0 ; /* level of disabled aux. msg printing */
553         debLevA =  1 ; /* level of minimum  aux. msg printing */
554         debLevB =  2 ; /* level of low aux. print (report read-file opening)*/
555         debLevC =  3 ; /* level of moderate debug prt (most pkgs debug msg) */
556         debLevD =  4 ; /* level of enhanced debug prt (add DEBUG_STATS prt) */
557         debLevE =  5 ; /* level of extensive debug printing */
558        New debugLevel default: with default debugMode value (=F),
559          = 2 (debLevB) or = 1 (debLevA) in case ALLOW_AUTODIFF is defined.;
560          and if debugMode=T, default debugLevel = 4 (debLevD).
561        Relation with previous settings:
562         debLevB (=2) corresponds to former debLevA (=1)
563         debLevD (=4) corresponds to former debLevB (=2)
564        Note:
565         a) if debugLevel=0, skip WRITE_GRID call when nIter0 > 0 (same as before);
566         b) default debugLevel=1 is convenient in AD runs (avoid many file opening msgs);
567            to recover previous default, set debugLevel=2 (e.g. AD-test hs94.1x64x5)
568      - Add new parameter (printResidualFreq, read from PARM02 namelist) to print
569        detailed CG solvers convergence; off (=0) by default, except if debugLevel=5.
570    o pkg/obcs:
571      - change OBCSfixTopo default from True to False (should not change the results);
572        keep OBCSfixTopo=T in verification-exp. seaice_obcs.
573    o pkg/thsice:
574      - fix bug in thsice_calc_thickn.F (was introduced in version 1.18) in
575        2nd layer seaice sublimation (unlikely to happen)
576      - use Interior mask for OBCS in thsice_advection.F (similar to what is
577        done in gad_advection & seaice_advection).
578    o adjoint:
579      bug fix spotted by Gael Forget:
580      seaice_advection and thsice_advection still had
581      legacy CPP options to avoid CS corner updates for adjoint
582    o pkg/seaice:
583      => Change some of the defaults (2011/05/29):
584         - change SEAICEuseFluxForm default (from False to True)
585         - change DIFF1 default (from 0.004 m/s to 0. m/s)
586         And print warnings if DIFF1 is not set in data.seaice and centered
587          avection scheme is used without any diffusion.
588      also:
589      - fix seaice_diffusion calls in default AdvScheme part of seaice_advdiff.F;
590      - set SEAICEdiffKh[] default in the same way as SEAICEadvSch[]
591      - stop if DIFF1<>0 with SEAICEadvScheme <> 2, if DIFF1<>0 with any
592        other non-zero SEAICEdiffKh[] diffusivity, if SEAICEadvSalt=T with
593        #undef SEAICE_VARIABLE_SALINITY, if SEAICEadvAge=T with #undef SEAICE_AGE.
594      update results of test exp.:
595         lab_sea: output.fd (switch to AdvScheme=33 with diffKh=20)
596             output.hb87, output_adm.evp (SEAICEuseFluxForm=T and diffKh=200)
597             output_adm.noseaicedyn (SEAICEuseFluxForm=T)
598         offline_exf_seaice: output.seaicetd, output_adm (SEAICEuseFluxForm=T)
599         seaice_obcs: output (SEAICEuseFluxForm=T)
600      and prescribe old default for SEAICEuseFluxForm (=F) and DIFF1 (=0.004)
601          for standard fwd & AD lab_sea tests (to keep the same output).
602    o pkg/seaice/seaice_growth.F:
603      - use Ian Fenty's capping formulas for actual ice
604      thickness thoughout EVOLUTION branch.
605      - put treatment pathological case #2) in CPP brackets
606      (ALLOW_AVOID_INFINITESIMAL_AREA, undef by default).
607      - update global_ocean.cs32x15 and 1D_ocean_ice_colum results accordingly.
608    o pkg/seaice:
609      - seaice_diffusion.F : remove the min(DX,DY) factor permanently;
610      pass the Laplacian diffusivity (in m^2/s) diffKh as a parameter;
611      also pass fac as a param, which can be 1. (to update the tendency
612      field) or the time step (to update the field itself).
613      - seaice_advdiff.F: for multidim, call seaice_diffusion with
614      e.g. SEAICEdiffKhHeff and with fac=1; for single-dim, call
615      seaice_diffusion with e.g. SEAICEdiffKhHeff and with fac=time step.
616      - SEAICE_PARAMS.h, seaice_readparms.F, seaice_check.F :
617      hooks to handle SEAICEdiffKhHeff, SEAICEdiffKhArea, etc.
618    o pkg/seaice:
619      diffusion with centered advection scheme (diffus.F & advect.F):
620      - simplify S/R DIFFUS (put deltaT & DIFF1 factor outside, move EXCH outside)
621        to just compute the laplacian of input-field.
622      - unroll k loop (harmonic,biharmonic diff) in advect.F to save 1 exch call.
623      - fix flux-form version in diffus.F to conserve tracer.
624      update output of lab_sea.fd & lab_sea.hb87 (1rst set of modif affects
625       machine truncation) and lab_sea.salt_plume (conservative flux-form modif)
626    
627    checkpoint62y (2011/05/26)
628    o pkg/seaice:
629     - seaice_growth.F : in EVOLUTION branch, always include
630       a_QSWbyATM_cover in qnet (as it should be).
631     - verification/global_ocean.cs32x15 : update results accordingly
632       (output.seaice.txt output_adm.seaice.txt).
633    o pkg/seaice + obcs:
634     - use maskInW & maskInS in multi-dim advection and biharmonic diffusion:
635       equivalent of assuming no tracer gradient outside the OB region.
636       update output of seaice_obcs (uses DIFF1 <>0 => biharmonic diffusion)
637     - remove calls to OBCS_COPY_TRACER after EXCH calls (no longer needed
638       after changes above);
639     - obcs+seaice cleaning: apply seaice-tracer OB values to tracer field
640       only at OB location (instead of over a band of OLx width).
641    o pkg/seaice:
642     - fix wrong indices in old (non Flux-Form) diffusion default S/R diffus.F
643       (dxG(I+1, ...) changed to dxG(I, ...), no impact on Lat-Lon grid)
644    o pkg/obcs:
645      - split header file "OBCS.h" into 4 separated files:
646        OBCS_PARAMS.h, OBCS_GRID.h, OBCS_FIELDS.h & OBCS_SEAICE.h
647       Note: OBCS_PARAMS.h & OBCS_GRID.h can be included without OBCS_OPTIONS.h
648         (contain no conditional statement which depends on OBCS options).
649      - move "useOBCSYearlyFields" from "data.obcs" (hold in OBCS_PARAMS.h)
650        to parameter file "data.exf", namelist EXF_NML_OBCS (in EXF_PARAM.h).
651    o ctrl, cost, grdchk & autodiff pkgs:
652      - make options file more standard (like other {PKG}_OPTIONS.h file but
653        with AD_CONFIG.h); clean-up some of the included header files.
654    o pkg/obcs:
655      - do not mask tracer when applying OB (tracer == 0 could generate problems)
656      - apply tracer OB values to tracer field only at OB location (instead of
657        over a band of OLx width)
658      - clean-up obcs_apply_w.F & obcs_apply_eta.F (since less calls to these S/R)
659      - remove OBCS_MULTIDIM_OLD_VERSION code in gad_advection.F and remove
660        obcs_apply_tloc.F & obcs_apply_sloc.F
661    o obcs in model/src:
662      - call OBCS_APPLY_W only if NonHydrostatic.
663      - call OBCS_APPLY_ETA only if NonLinFreeSurf.
664      - reset dEtaHdt and wVel to zero outside OB interior region ;
665      - leave tracer unchanged outside OB interior region: This has no effect
666        on the solution but just to prevent unrealistic tracer value outside OB.
667      - zero out velocity outside OB interior region: This has no effect on
668        the solution but just to prevent unrealistic velocity outside OB.
669    o obcs and non-lin free-surf:
670       move call to OBCS_APPLY_R_STAR from update_r_star.F to calc_r_star.F
671       and call to OBCS_APPLY_SURF_DR from update_surf_dr.F to calc_surf_dr.F
672       + add argument "etaFld" to OBCS_APPLY_R_STAR & OBCS_APPLY_SURF_DR:
673       this fixes missing EXCH + get consistent eta OB value (+ fix restart).
674       update results of test-exp. exp4(nlfs).
675    o exp4 (nlfs) test-exp:
676       use OBC for Eta at Western & Eastern OB (to test prescribing Eta
677       with NonLin-FreeSurf); update output.nlfs.txt
678    o obcs and 2d/3d solver norm:
679       use interior masks (maskInC) to cancel out cg2d & cg3d matrix coeff at OB
680       and outside OB interior region (will allow to place OB further inside the
681       domain). Depending on the domain, can affects cg2d-Norm (previous
682       cancellation outside OB was only partial), e.g. in exp4 & obcs_ctrl,
683       and cg3d-Norm (previous Norm was computed before canceling OB terms),
684       e.g. in tutorial_plume_on_slope.
685      - update output of exp.: exp4 (x2), obcs_ctrl and tutorial_plume_on_slope.
686    o pkg rbcs:
687      - split RBCS.h into 3 files: RBCS_SIZE.h, RBCS_PARAMS.h & RBCS_FIELDS.h
688      - add capability to apply relaxation to horizontal velocity uVel & vVel.
689    o pkg/grdchk: add gradient check for control variable xx_shifwflx
690    o pkg/shelfice/shelfice_init_fixed.F
691      fix CPP-flag combinations
692    o pkg/seaice: Merge iceage code of Pierre Rampal
693      * update/change/correct ice age calculations
694      * add age updates for pathological cases
695      Probably needs more testing...
696    
697    checkpoint62x (2011/05/13)
698    o pkg/mom_vecinv:
699       high-order vorticity scheme: use interior masks (maskInW & S)
700       to zero-out (outside OB) gradient of vorticity.
701    o verification exp.:
702       turn on "useEnergyConservingCoriolis" (better discretisation) in exp.
703       hs94.128x64x5 and seaice_obcs ; update results.
704    o pkg/obcs:
705      fix bug in OBeta for YZ sections in obcs_exf_load.F
706    o pkg/ctrl, pkg/shelfice, and optim:
707      - add new control variable xx_shifwflx (fresh water flux underneath ice
708        shelves). This is almost as tedious as obcs-ctrl, because the
709        variables needs its own mask.
710      - add a cost function term that penalizes the deviation of xx_shifwflx
711        from the first guess (zero) in analogy to other control variables
712    o pkg/shelfice:
713      - start basic adjoint
714    o pkg/ctrl:
715      - remove extra 2D field "for good measure" when initializing in
716        ctrl_set_globfld_[xy/xz/yz].F
717      - replace hard coded precision 32 (a bug) in ctrl_map_ini_gen by ctrlprec
718      - improve error messages in ctrl_set_unpack_*
719    o OBC implementation in momentum:
720       use interior masks (maskInC,W & S) in momentum S/R:
721       - multiply divergence, tension and some del^i.u or del^j.v by maskInC
722       - multiply del2u,del2v by maskInW/S (biharmonic viscosity)
723       - multiply horiz. grad of vorticity by maskInW/S (in Leith scheme)
724       - multiply gradient of wVel by maskInW/S in del2w calculation (NonHyd)
725       Motivation: fix/clean implementation of OBC with biharmonic-viscosity
726        (and also with Leith/Smagorinsky harmonic-viscosity).
727       Update output of experiment dome and exp4 (+nlfs).
728    o exp4 test-exp:
729      - turn on: nonHydrostatic, exactConserv, viscA4 (with momDissip_In_AB=F)
730        and prescribe time-varying OB (without pkg/exf) for zonal-velocity
731        at Western & Eastern Boundaries (+/- 1 per-cent); Also prescribe
732        time-varying OB at Western-side for wVel (NonHyd); update output.
733      - add secondary set-up (.nlfs) using NonLin FreeSurf (z*) + mom_vecinv
734        and biharmonic-viscosity ; also use prescribed time varying OB.
735    o pkg/obcs:
736      fix bug in OBWeta,OBWeta indices in obcs_apply_r_star.F
737    o model/src:
738      - fix startTime setting when baseTime<>0 & nIter0=0 are specified ;
739      - initialise startTime & nIter0 with unlikely values: allows to set one
740        from the other without ambiguity.
741    o seaice_obcs test-exp.:
742      add small diffK4T,S to test biharmonic diffusivity with OBCS ; update output.
743    o pkg/obcs:
744      - remove calls to OBCS_COPY_TRACER after EXCH for T,S & pTracer:
745        no longer needed with maskInC,W,S in pkg/generic_advdiff.
746    o pkg/seaice:
747      - retired SEAICE_SALINITY and SEAICE_salinity in favor of
748        SEAICE_VARIABLE_SALINITY and SIsalFRAC, respectively.
749      - fixed bug in the initialization of sea ice salinity variable HSALT
750        in seaice_init_varia.F  (removed dependence on ICE2WATR)
751    o fizhi-cs test exp.:
752       switch reference output convention for these 2 non-standard test-exp,
753        from: pgi  6.1-5 on faulks (FC.6, -of linux_ia32_pgf77+authors_fc5)
754          to: ifort 11.1 on baudelaire (FC.13, -of linux_amd64_ifort11)
755       reason: faulks might get retired soon and pkg/fizhi has still Pb with gfortran
756    o model/inc:
757      - change type of PmEpR array (from _RS to _RL) to fix restart (with "-use_r4")
758        of exp. global_ocean.90x40x15 (Suncronous time-stepping + Real-FW + NonLin-FS)
759    o pkg/seaice:
760      - fix calculation of saltFlux and saltPlumeFlux when using SEAICE_SALINITY
761    o verification/lab_sea, 1D_ocean_ice_column, seaice_obcs, global_ocean.cs32x15
762      - updated output*.txt files due to bug fixes in salt, saltPlumeFlux,
763        and initial HSALT
764    
765    checkpoint62w (2011/04/26)
766    o pkg/mom_fluxform:
767      - fix calculation of del2u & del2v (no-slip BC) when using Non-Lin Free-Surf.
768      - use parameter "sideDragFactor" in no-slip BC side-drag part.
769      - update output of exp. global_ocean.90x40x15
770    o pkg/mom_vecinv:
771      mask del2u & del2v (no effect on results, but cleaner & closer to mom_fluxform)
772    o update seaice exp.:
773      use more consistent parameter values (remove "backward compatability only":
774       ICE2WATR, SEAICE_lhSublim, SEAICE_cpAir, SEAICE_rhoAir + set rhoConstFresh)
775      related to thermodynamics seaice. Update output (fwd+AD) of exp.:
776       1D_ocean_ice_column (x2), lab_sea (x8), ioffline_exf_seaice (x2) & seaice_obcs
777    o update test-exp global_ocean.90x40x15:
778      o use default CD_CODE_OPTIONS file (Adams-Bashforth on CD Mom & Coriolis).
779      o increase Overlap size from 2 to 3 (to allow to test bi-harmonic Visc.)
780      o new pickup-files from a 100.yr run with pkg/down_slope (input.dwnslp params)
781      o turn on zStar & viscA4 in standard set-up (dir input/)
782        and update output files: output.txt & output.dwnslp.txt
783    o new AD-test experiment: obcs_ctrl
784      (From Matt MITgcm_Contrib/SOSE/BoxAdj) to test OBCS as control vector.
785    o pkg/dic:
786      fix two bugs in handling water vapour pressure in carbonate chemistry
787      and air-sea fluxes. Found by Val Bennington and Galen McKinley
788      (add DIC Option = WATERVAP_BUG to recover old results)
789      update output of tutorial_global_oce_biogeo (fwd+AD) & tutorial_dic_adjoffline
790    o adding allowInteriorFreezing option to check for water below freezing point
791      at depth and bring the negative heat anomaly to the surface level
792    o pkgs _fields_load:
793      - extend GET_PERIODIC_INTERVAL to deal with non-periodic case (from pkg/rbcs)
794      - use new S/R GET_PERIODIC_INTERVAL in pkgs:
795        bulk_force, cheapaml, cfc, dic, obcs (+ ctrl/ctrl_get_gen_rec), offline and
796        rbcs to get interpolation weights and time reccord number.
797      - fix multi-threading in aim_fields_load.F
798      - apply EXCH to temp arrays [0,1] after reading in dic_fields_load.F
799    o external_fields_load:
800      new S/R GET_PERIODIC_INTERVAL to calculate which time-record (and linear
801       interpolation weights) to use in a periodic time-series ; do not divide by
802       time-step to convert to integer:
803       - this fixes case where externForcingPeriod is not multiple of time-step
804          (Thanks to Christopher L. Wolfe)
805       - this fixes case where externForcingPeriod is an odd multiple of time-step
806         (was wrong by half of time-step); update results of tutorial_global_oce_in_p.
807      store index of time-record which is currently loaded:
808       - works without any assumption on sequence of calls to EXTERNAL_FIELDS_LOAD ;
809       - needed for the adjoint but not yet used because of extensive recomputations;
810         (to be fixed soon)
811    
812    checkpoint62v (2011/04/02)
813    o verification/1D_ocean_ice_column added to test Ian Fenty's
814      pkg/seaice_growth.F modifications for improving sea ice code differentiability
815    o update output of exp4, internal_wave, seaice_obcs, tutorial_plume_on_slope
816      (new velocity statistics after changing maskInW & maskInS definition)
817    o pkg/generic_advdiff with OBCS:
818      use maksInW & maskInS in advective flux and in biharmonic diffusion calculation:
819      equivalent to assumption of no tracer gradient outside the OB region.
820      This will affect the results if using obcs+biharmonic diffusion.
821      update output_adm.txt of experiment bottom_ctrl_5x5 (not expected since no obc)
822    o pkg/obcs:
823      change definition of maskInW & maskInS: leave OB edges inside (maskIn=1)
824      (e.g., maskInW(OB_Ie)=1 ) so that velocity normal-component at OB is still
825      in Interior region. No impact on solution but affects Velocity monitor stats.
826    o pkg/ptracers (adjoint)
827      New option AUTODIFF_PTRACERS_SPLIT_FILES for writing separate
828      tape file for each tracer
829    o model/inc/src and pkg/autodiff: add parameters that allow to turn
830      of parts of the adjoint code at run time. For now, there are only
831      useKPPinAdMode, useGMrediInAdMode, and useSEAICEinAdMode. These
832      parameters are set in data.pkg.
833      This is the lazy coward's version of doing this, but still useful for
834      debugging. In order to do it right, everything needs to be moved to
835      pkg/autodiff.
836    o pkg/autodiff: fix global_sum_tile_ad.F by resetting adsumPhi at
837      the end; this fixes the adjoint balancing code for open boundaries.
838    o pkg/ctrl:
839      - change behavior of xx_${varname}period to be analogous to exf-conventions:
840        xx_${varname}period =   0.,  means time-independent control part
841        xx_${varname}period = -12., means one-year-periodic monthly control part
842      - introduce helper routine ctrl_init_rec (part of ctrl_init.F) to
843        clean up ctrl_init a little, remove unused variables
844      - ctrl_init: fixed the handling of the start/endrec for obcs-variables
845      - move "call cal_GetMonthsRec" from s/r ctrl_get_gen to s/r ctrl_get_gen_rec
846    
847    checkpoint62u (2011/03/15)
848    o model/src:
849      - for the adjoint, change NonLin-FreeSurf initialisation sequence: fill-in
850        h0Fac from INITIALISE_FIXED and reset hFac to h0Fac in INITIALISE_VARIA ;
851      - in initialise_varia.F (except for ALLOW_DEPTH_CONTROL) remove 2nd call to
852        INI_DEPTHS, INI_MASKS_ETC & INI_LINEAR_PHISURF.
853    o pkg/ctrl/obcs/ecco:
854      - remove obsolete, unused, and partially broken code:
855        ctrl_obcsvol/ctrl_obcsbal/ctrl_volflux and code within
856        ALLOW_CTRL_OBCS_BALANCE
857      - put a stop statement into ecco/cost_obcsvol.F, but also add
858        cost_obcsvol to ecco_ad_diff.list
859    o pkg/ecco: fix counting cost function contributions for obcs (code
860      by Matt M.) and diffkr for diagnostics
861    o pkg/ecco, pkg/ctrl, pkg/grdchk:
862      add cost penalty terms for initial uvel, vvel, eta controls
863      and I/O for prior error files
864    o pkg/mdsio:
865       move mds_check4file.F from eesupp/src to mdsio_check4file.F ; add option
866       (new argument) to check for tiled file in mdsioLocalDir : this fix the
867       restart from pickup_som , pickup_dic (& dic_co2atm) with mdsioLocalDir.
868    o pkg/ctrl:
869     - ctrl_obcsbal.F, ctrl_obcsvol.F: replace last calls of ctrl_getrec by
870       ctrl_get_gen_rec, put a stop statement into ctrl_getrec. Remove
871       unused and superfluous variables
872     - ctrl_get_gen_rec.F: catch the case of xx_genperiod=0.
873    o pkg/ecco
874     - enable adjoint of Stevens OB
875    o pkg/ctrl/ecco/grdchk:
876      - remove global declaration of tmpfldx/yz and tmpfldx/yz2.
877        Fortunately, we do not have any tests for the numerous cpp-flagged
878        option of "obcs as control parameters" so we will never know
879        if this is an improvement (but at least now things compile).
880      - remove an obsolete initialization from ecco_cost_init_barfiles.F
881      - fix some problems within never used ifdefs to make the code compile
882    o pkg/obcs:
883     - Refine Interior mask definition to work with more complex OB (e.g.
884       if OB_Ie < OB_Iw); In case default setting is not sufficient, allows to
885       read in Interior mask from file. Check if Interior mask is consistent
886       with OB list of indices.
887    o pkg/seaice
888     - beginning code for a seaice tracer package,
889       but currently only used for seaice age: SEAICE_AGE
890       SEAICE_num = 4
891       iTracer = 1: area-weighted ice age
892               = 2: volume-weighted ice age
893               = 3, 4: template for one-year vs. multi-year ice
894       data.seaice has new namelist SEAICE_PARM03 for arrays related to
895       SEAICE_num
896    
897    checkpoint62t (2011/03/05)
898    o pkg/obcs:
899     - obcs_apply_uv.F: change to a 2 steps method, first tangential component;
900       then normal component. This ensures that the normal component is set
901       correctly even when it conficts with tangential setting from an other OB.
902       Affects results of test-experiment seaice_obcs: update the output.txt
903    o pkg/obcs:
904     - add code to monitor statistics of dynamical fields at OB.
905     - take OBCS_BALANCE code out of obcs_calc.F into new S/R OBCS_BALANCE_FLOW :
906       - fix to OBCS_BALANCE code (right hFac ; deal with simple OB intersection).
907       - change default: balance the Net inflow through all OB (instead of balancing
908         each OB separately); keep the old method if setting OBC_balanceFacX < 0.
909     - switch on useOBCSbalance in dome experiment: only correct Western OB outflow
910       to match Nortern OB inflow (OBCS_balanceFacN=0).
911    o pkg/seaice:
912     - redefined actual sea ice age to be ICEAGE/HEFF ifdef SEAICE_AGE_VOL
913    o pkg/seaice (seaice_growth v 1.113):
914     - reverting seaice_growth to v 1.111 in order to have code with exact bit
915       compatibility with MITgcm_contrib/ifenty/Fenty_seaice_thermo_code_merge
916       CPP option SEAICE_OCN_MELT_ACT_ON_AREA removed in v 1.112 is reintroduced
917       runtime flag SEAICEareaFormula is kept but is inactive
918    o model/src:
919     - add new param to scale curvilinear grid distance and area when using
920       a different sphere radius from the grid-files.
921     - test/check multi-threads EXCH applied to local variable (cg2d_x)
922    o adjoint:
923     - enable adjoint of Stevens OB
924     - add dummy_in_dynamics to enable extraction of ADJrhoinsitu
925       (a bit delicate because of potentially modified adj. common block structure;
926       current switch is ALLOW_AUTODIFF_MONITOR_DIAG, could be changed later)
927    
928    checkpoint62s (2011/02/15)
929    o pkg/seaice (seaice_growth v 1.112):
930     - introduce SEAICEareaFormula run time parameter, which selects the recipe for
931       computing the ice cover tendency from effective thickness tendencies. Include
932       Ian Fenty's formula.
933     - remove 'undef SEAICE_OCN_MELT_ACT_ON_AREA' which may now be achieved using
934       SEAICEareaFormula.
935     - simplify notations for the various d_HEFF/d_AREA terms.
936    o pkg/gmredi:
937     - add Boundary-Value-Problem bolus transport (Ferrari etal, OM 2010) code
938       from Christopher Wolfe (UCSD); add partial cell factor in vertical derivative;
939       add a verification test-run (front_relax.bvp) to test GM_useBVP.
940    o pkg/seaice (seaice_growth v 1.111):
941     - for SEAICE_DO_OPEN_WATER_GROWTH, replace Gael's implementation with Ian's.
942     - the new SEAICE_DO_OPEN_WATER_MELT allows open-water air-sea heat fluxes to
943       also melt ice.
944    o pkg/seaice:
945     - McPhee formula for Ice-Ocean fluxes (provided by Ian Fenty).
946     - can be used by #define MCPHEE_OCEAN_ICE_HEAT_FLUX in SEAICE_OPTIONS.h
947    o pkg/cheapaml:
948     - from Nico Wienders: New version of this package.
949    o pkg/flt:
950     - add CPP options to prevent floats to re-enter the opposite side of
951       a periodic domain (default: keep periodicity)
952    o pkg/gmredi:
953     - apply exchange to GM_PsiX,GM_PsiY to get valid values near CS-corners
954       (needed for multi-dim advection).
955     - switch on GM Advective form in global_ocean.cs32x15 and update output.txt
956    o model/src:
957     - fix wrong re-setting of addMass array (ALLOW_ADDFLUID) for atmospheric run.
958    o tutorial_tracer_adjsens
959     - extend to NLFS and replace maskC by hFacC
960       (change reference output accordingly)
961    
962    checkpoint62r (2011/01/24)
963    o testreport:
964     - add option -deloutp (-do) to remove output file after successful run
965     - add option -mfile (-mf) for MPI machile-file and for each test-exp,
966       extract exact list of procs from this file ; adjust COMMAND by
967       replacing TR_MFILE & TR_NPROC with local machile-file & Nb of MPI procs.
968    o pkg/ecco: replace old ineffective way of penalizing deviations from
969      first guess (of obcs) with code by Matt Mazloff
970    o pkg/ctrl: add code that allows the use of ALLOW_OBCS?_CONTROL without
971      exf/cal
972      - ctrl_init: fix initialisation (computation of diffrec) for obcs-ctrl
973        and handle case of obcs?period == 0
974        Not affected by these changes: There is still an inconsistency in
975        the computation of start/endrec for the obcs variables for ALLOW_CAL
976        defined (see comment by Menemenlis, 7-Mar-2003)
977      - make S/R ctrl_get_gen_rec return something meaningful even if
978        ALLOW_CAL is not defined
979      - ctrl_getobcs?: simplify code so that it does not need to use
980                       S/R exf_swapfields
981    o testreport:
982       allow to test MPI with different number of processors for each experiment:
983       create file "SIZE.h.mpi" in each build dir.
984       Note: update of "-command" argument not yet implemented.
985    o model/src, pkg/autodiff, pkg/ecco, pkg/seaice:
986      alleviate the need for additional 3D tapes when using
987      the non-inear free surface in the adjoint. This is done
988      by adding an 'update' of hfacc etc. to their current
989      value at the beginning of forward_step.F.
990    o pkg/seaice
991      seaice_lsr: move stress-divergence computations out of outer pseudo-
992      timestepping loop
993    o pkg/obcs/obcs_prescribe_read.F: move 'CALL OBCS_EXTERNAL_FIELDS_LOAD'
994      up, so that the calls of the ctrl_* subroutines are really at the end
995      of the routine.
996    o pkg/gmredi:
997      allow to specify a 2-D horizontal map and a 1-D vertical profil
998      as scaling factor for Isopycnal diffusivity (Redi) and GM diffusivity.
999    o pkg/seaice:
1000      move lsr iterations from seaice_dynsolver to seaice_lsr.
1001    o pkg/seaice:
1002      reduce memory footprint of seaice mutldim advection tapes,
1003      by using a 2D tape independent of the generic_advdiff ones,
1004      and setting GAD_AREA=1 etc. rather than GAD_AREA=101 etc.
1005    
1006    checkpoint62q (2010/12/29)
1007    o model/src:
1008      - check horizontal grid-spacing for unset or zero/negative values.
1009      - change AD test hs94.1x64x5 to be truly a 2-D set-up.
1010    o pkg/flt:
1011      - use (recent) mdsio S/R MDS_READVEC_LOC instead of local FLT_MDSREADVECTOR
1012      - precision of input and output files set according to readBinaryPrec
1013        and writeBinaryPrec (previously always 64.b), pickup remains at 64 bits.
1014      - initial float position from tiled file was not converted to index space
1015        (looks like a bug): fixed to make it similar to initial pos. global file.
1016    o global_ocean.cs32x15:
1017       change SIZE.h of AD set-up to get same tiling as with MPI.
1018       Update output_adm, output_adm.thsice (pass@14) & output_adm.seaice (fail@11)
1019    o model/src:
1020       add flag to control printing of domain fields (bathymetry, hFac ...) in
1021       ini_mask_etc (call to plot_fieds_xy*).
1022    o pkg/thsice:
1023       if useEXF, some forcing fields are not valid in overlap: fixed by computing
1024       over the interior only + apply EXCH at the end (like with SEAICE advection).
1025    o pkg/mdsio:
1026      - add 2 arguments to S/R MDS_PASS_R4/8toRL/S for overlap size of buffer
1027        to copy to/from, so that it can be used to replace MDS_PASS_WH_R8toRL/RS.
1028      - change barrier call for safe multi-threads access to 3-D shared buffer.
1029      - MDS_READ/WRITEVEC_LOC use buffers from MDSIO_BUFF_3D.h (instead of local ones)
1030      - replace call to MDS_PASS_WH_R4/8toRL with call to MDS_PASS_R4/8toRL and
1031        remove the 4 S/R MDS_PASS_WH_R4/8toRL/S.
1032    o pkg/flt:
1033      - add fourth-order Runge-Kutta integration
1034      - add basic exch2 support (only 1 facet supported so far!)
1035    o pkg/mdsio+rw:
1036      new S/R to read local (or tile independent) vector (read counterpart of
1037       mds_writevec_loc, and front-end write_glvec_rl/rs).
1038    o global_ocean.cs32x15: additional input_ad.seaice experiment
1039        that uses pkg/seaice rather than pkg/thsice.
1040        (using multidim advection for seaice)
1041    o towards more F95 syntax for array specification in namelist:
1042      - change "data.diagnostics" (data.ptracers was changed before checkpoint62p)
1043        of all verification experiments.
1044           e.g.:    line: fields(1,3)='ETAN    ','ETANSQ  ',
1045          was changed to: fields(1:2,3)='ETAN    ','ETANSQ  ',
1046      - finish adding "-DNML_EXTENDED_F77" to DEFINES list in pgf77 and g77 optfiles
1047    o global_ocean.cs32x15: additional input.seaice experiment
1048        that uses pkg/seaice rather than pkg/thsice.
1049    
1050    checkpoint62p (2010/12/17)
1051    o pkg/thsice: rename (ad tape index) iicekey as ticekey, and move it
1052        to THSICE_SIZE.h to avoid conflict with pkg/seaice.
1053    o pkg/seaice: add seaice_diffusion.f seaice_map_thsice.f to adjoint.
1054        allow for use of multim. advection in seaice adjoint.
1055    o pkg/seaice: add diagnostics for snow precipitation and sublimation flux
1056      - first attempt to close budgets by taking into account the freshwater
1057        flux implied by the sublimation of snow and ice. So far only the
1058        volume budget is closed, turn on with soon-to-be-retired-again CPP-Flag
1059        SEAICE_ADD_SUBLIMATION_TO_FWBUDGET
1060    o eesupp/src:
1061      new S/R with new option (NML_EXTENDED_F77) to change array specification
1062      from F95 standard to commonly accepted extended F77 form.
1063      This would allow to use F95 syntax in namelist (needed with gfortran 4.4.5)
1064      and to revert back to the original syntax (with -DNML_EXTENDED_F77)
1065      for less tolerant f77 compiler (e.g., pgf77, g77).
1066    o globalFiles:
1067      commented out in parameter file "data" since it's not safe with MPI
1068      (e.g., wrong on aces); keep it if useSingleCpuIO=T (but not doing much
1069      in this case); no longer commented out in restart test (tst_2+2).
1070    o add adTapeDir to specify a special directory where adjoint tapes are
1071      written/read (adread_adwrite.F). adTapeDir is specified in data/PARM05
1072      and cannot be used together with mdsioLocalDir.
1073    o nesting pkgs:
1074      - packages_init_variables : put call to OBCS_INIT_VARIABLES in last position
1075      - update Gianmaria's Nesting pkgs (from Contrib/nesting_sannino)
1076      - add parameter files + utils dir + output from short run on beagle.
1077    o pkg/seaice:
1078        fix seaice_growth.F store directives; update results of exp. lab_sea.ad
1079    o pkg/seaice: explicitly store tsurfloc in seaice_solve4temp.F to avoid
1080      unnecessary copying in adjoint code, requires new parameter NMAX_ITER
1081    
1082    checkpoint62o (2010/11/25)
1083    o pkg/exf:
1084      - change CPP option EXF_VERBOSE to run-time logical param exf_verbose.
1085    o pkg/seaice:
1086      - seaice_ocean_stress: split a loop for better vectorization of the
1087        adjoint code
1088      - seaice_growth.F: fix bug in conservation of freshwater connected to
1089        capping of heff, put contribution into d_HEFFbyNEG
1090      - replace irritating parameters SEAICE_latentWater/Ice and SEAICE_sensHeat
1091        by something more sensible (parameters that are what their name implies)
1092      - change some defaults, so that by default exf-parameters are used for
1093        things like rhoAir, cpAir,latent/sensible heat parameters, in order
1094        to reproduce the old results, many data.seaice now contain funny values
1095        for cpAir and latent heat of sublimation
1096    o packages_readparms.F: move exf_readparms up in line so that
1097        exf-parameters are visible for other packages (e.g. seaice)
1098    o debugMode & debugLevel=2:
1099      - differentiate between debugMode & debugLevel=2:
1100        debugMode: controls printing of debug messages (sequence of S/R calls).
1101        debugLevel: controls printing of algorithm intermediate results and stats.
1102      - remove "if debugLevel=2 => debugMode" but keep "debugMode =>  debugLevel=2";
1103        => allows to print debug-stats without all sequence of call messages.
1104      - switch control of debug print from debugLevel to debugMode in many S/R.
1105    o pkg/obcs (obcs-sponge):
1106        fix bug that was introduced on Oct 25 (in dynamics.F v1.151): put back the
1107        call to OBCS_PRESCRIBE_EXCHANGES (need to exch gU,gV when using obcs-sponge)
1108    o pkg/generic_advdiff:
1109      - record overlap minimum size for each advection scheme;
1110      - refine criteria on overlap minimum size;
1111      - check and stop (in gad_check) if overlap size is too small.
1112    o pkg/obcs:
1113      - with ptracers: remove multiple calls to obcs_apply_ptracer (only done
1114        once, in ptracers_implicit.F)
1115      - with seaice: remove test on empty file name in obcs_apply_seaice (always
1116        apply OB values when tile has OB)
1117    o model/src, coriolis setting:
1118      - integer parameter "selectCoriMap" (=0,1,2) replaces 3 logical
1119        useConstantF, useBetaPlaneF, useSphereF ; can now read coriolis from
1120        files (selectCoriMap=3) with any grid.
1121      - add parameter "fPrime" for constant second Coriolis coeff (default=0).
1122    o pkg/seaice/seaice_growth.F:
1123        a few cosmetic changes that reduce the number of lines of code
1124    o pkg/obcs: add boundary conditions following Stevens (1990)
1125      - the code follows old MOM/NAOSIM code
1126      - so far it is only implemented for the eastern and western boundaries
1127        and NOT for pTracers
1128    o pkg/rbcs:
1129      - replace rbcsInIter by rbcsForcingOffset, the time in seconds at the
1130        beginning of the first rbcs forcing period.
1131      - add option rbcsSingleTimeFiles that makes rbcs read forcing data like the
1132        offline package, i.e., one file per time, labeled by iteration number;
1133        deltaTrbcs sets the timestep with which the data was generated;
1134        rbcsIter0 is the forcing iteration corresponding to rbcsForcingOffset.
1135      - rbcsForcingCycle=0 makes forcing non-cyclic.
1136      - make arithmetic safe for negative times and odd forcing periods.
1137    
1138    checkpoint62n (2010/11/09)
1139    o pkg/seaice:
1140        fix masking in free-drift S/R ; update results of exp. lab_sea.fd
1141    o pkg/obcs:
1142       New S/R to copy tracer value from the OB location to narrow band region
1143        (width = same as overlap) beyond the OB: preserve OB value (needed for
1144        high-order scheme) which were overwritten by EXCH call if in overlap
1145        region. Applied to theta, salt, ptracer and advected seaice variables.
1146       With seaice: use maskInC in similar way as in gad_advection.F,
1147        in seaice_advection.F and advect.F.
1148       Update output of experiment seaice_obcs and change exp4 to test OBCS with
1149        4th order Adv.Scheme. for pasive salt and ptracer.
1150    o tools/genmake2:
1151      - when looking for an optfile (not specified), only search for Fortran compiler
1152        (remove sym-link test + setting of CPP + makedepend check + C-compiler check)
1153      - in get_fortran_c_namemangling: use "$CC $CFLAG" to compile C test programm
1154        (instead of "$MAKE genmake_test.o" since an existing Makefile can be wrong)
1155      - set default for CPP to "cpp -traditional -P" (was the case without specifying
1156        an optfile, but otherwise default was just "cpp".
1157      - comment out PLATFORM=$p_PLATFORM (no idea where p_PLATFORM comes from)
1158      - when "CC" is not set in the optfile, look for possible C compiler
1159        (instead of just setting CC=cc)
1160      - put back version v.169 modif (from 2008/02/15), was dropped in v.173 changes:
1161        => add a ".F" to ".o" rule for source files with no "#include" (such as
1162           port_rand.F); otherwise, default ignores FOPTIM and just uses FFLAGS.
1163      - move gfortran before g77 in list of possible Fortran compiler (consistent
1164        with reference compiler switch from g77 to gfortran)
1165    o pkg/seaice:
1166      o remove SEAICE_OLD_AND_BAD_DISCRETIZATION-code, add a test to
1167        seaice_check that stops the model, when the CPP flag is used.
1168      o seaice_growth.F: make capping of ice volume conserving by returning the
1169        capped ice as freshwater to EmPmR. This does not change the verification
1170        experiments but will change runs where the capping is acutally active
1171    o change reference platform+compiler from faulks+g77 to baudelaire+gfortran
1172      (except the 2 fizhi test exp.); update output of exp.: bottom_ctrl_5x5,
1173         global_ocean.cs32x15 (icedyn, thsice, AD thsice), global_ocean_ebm (AD),
1174         lab_sea (fd, hb87, salt_plume), MLAdjust (3/5) and vermix (dd)
1175    o tools/genmake2:
1176      - merge genmake_warnings & genmake_errors into 1 log file: "genmake.log")
1177      - change DUMPSTATE default to false (can use "-ds" option to switch it to T)
1178      - clean previous genmake log files before anything else.
1179      - change Makefile to remove testreport log files (*.tr_log) and genmake log
1180        files only with "CLEAN" target (instead of "Clean");
1181    o pkg/generic_advdiff:
1182      Change OBCS in multiDim advection (gad_advection.F):
1183       Use maskInC to prevent intermediate update of tracer-field in OB regions,
1184       thus keeping current-time-step OB values; and remove the call to OBCS_APPLY
1185       which were applying future time-step OB values.
1186      This way, all explicit calculations use current-time-step OB values
1187       (simpler and more consistent).
1188      Affects results when set-up uses time-varying OBC and multi-dim advection;
1189       update output of experiment seaice_obcs.
1190    o pkg/seaice:
1191      move OPTIONS (formerly locally defined) to SEAICE_OPTIONS.h:
1192       this includes SEAICE_GROWTH_LEGACY (+ SEAICE_DO_OPEN_WATER_GROWTH &
1193         SEAICE_OCN_MELT_ACT_ON_AREA ) and SEAICE_SOLVE4TEMP_LEGACY.
1194      Default (pkg/seaice/SEAICE_OPTIONS.h) is to define SEAICE_SOLVE4TEMP_LEGACY
1195       but leave SEAICE_GROWTH_LEGACY undef ; For now, keep verification exp
1196       unchanged (SEAICE_GROWTH_LEGACY defined in */code*/SEAICE_OPTIONS.h)
1197    o pkg aim (2010/10/26):
1198      - Introduce ALLOW_INSOLATION, moving toward a more general incoming solar radiation
1199        formulation with obliquity, eccentricity, ... as run-time parameters,
1200      - Introduce diagnostics for top-of-the-atmaophere incoming solar radiation and
1201        upward shortwave radition at the surface (all-sky and clear-sky).
1202    o pkg/obcs:
1203      - writing sections with globalFiles=T does not work: switch to tiled-files
1204        when writing sections for OBCS (change pkg/rw/write_rec.F accordingly).
1205      - fix index bug (OB_Ie -> OB_Iw_) in obcs_apply_uvice.F
1206      - apply OBCS_SEAICE_COMPUTE_UVICE to both uice and vice at all obcs
1207    
1208    checkpoint62m (2010/10/21)
1209    o pkg/seaice: vectorize seaice_solve4temp.F
1210      - move iterations loops outside of i/j-loops
1211      - requires 2D arrays for TB and effConduct
1212      - add 2D iceOrNot to replace HICE_ACTUAL.GT.0, as HICE_ACTUAL is
1213        modified in this routine
1214      - a little bit of clean up, adjusting indentation, etc.
1215      - replaced a few TEN**a by exp(a*log(10.)) in new code for better
1216        performance and '**TWO' by '**2' (because TWO is a float),
1217        replaced ONE, ZERO
1218    o eesupp/src:
1219       fix flow dir for exch1_z_RX_cube, exch1_uv_RX_cube & exch1_bg_RX_cube
1220    o pkg/seaice/seaice_growth.F
1221      Revision 1.89 of seaice_growth.F completes the overall october 2010 revision and
1222      merging process. The merged routine has two branches, and one activates the 'evolution'
1223      branch by setting SEAICE_GROWTH_LEGACY to undef (at the top of the routine for now).
1224      In summary, here is what the '10/10 revision' did consist of
1225        part 1: seaice_growth.F revisions 1.71 to 1.75
1226          - Preliminary seaice_growth.F clean-up, keeping test results strictly unchanged.
1227            The emphasis here was on improving readability (e.g. by trying to use meaningful
1228            variable names) and modularity (e.g. by adding arrays to store heff etc. updates).
1229        part 1.5:
1230          - revising the lab_sea experiment to make it a more useful (i.e. stable
1231            and representative of an actual model run). This was done by generating a
1232            (winter) pickup to start from, switching back the main experiment dynamic
1233            solver from evp to lsr, having one of the experiments use the free drift solution.
1234        part 2: seaice_growth.F revisions 1.76 to 1.85
1235          - Sorting out hard-coded constants that prevented heat and fresh water conservation.
1236          - Sorting out the various fields units and sign (set early on and reset at the end)
1237            to avoid numerous scalings/re-scalings. By v1.85 the basic unit for ice, heat and
1238            fresh water stock is 'effective ice meters', and >0 implies more ice/snow.
1239          - Using tendency terms arrays (d_HEFF* etc.) to alleviate remaining code locks,
1240            and simplifying logical expressions to further improve readibility.
1241        part 3: seaice_growth.F revisions 1.86 to 1.89
1242          - Re-organize the blocks of code more logically.
1243          - Merging the '_if.F' pieces that add something new.
1244    o pkg/thsice:
1245      - vectorize thsice_solve4temp and thsice_get_exf.
1246        Problem: thsice_solve4temp has an unvectorizable statement that
1247        might also be problematic for TAF
1248      - thsice_get_exf: add the ALLOW_BULK_LARGEYEAGER04 CPP-flag. This
1249        does not change the verifcation experiment, but will change all
1250        experiments that have this flag undefined (not tested in verification);
1251        a little reorganization to save a few 2D fields and recomputations
1252      - 1st step of revisiting thsice adjoint (major recomp. sorted out)
1253      - 2nd step:  fix some store dirs
1254        o seems to work somewhat, i.e. using ifort but not g77
1255        o likely cause are incomplete init. or recomputation
1256        o start verification/global_ocean.cs32x15/input_ad.thsice
1257    o pkg/obcs: add support for exch2
1258      - the position of the boundary and prescribed values are specified using
1259        a global domain with exch2 facets stacked
1260        - in x for N,S boundaries (like W2_mapIO=-1)
1261        - in y for E,W boundaries (so E,W boundaries do not overlap)
1262    o pkg/mdsio: add support for writing global sections with exch2
1263        file layout is as for obcs described above:
1264        - for x-z sections, facets are stacked in x (like W2_mapIO=-1)
1265        - for y-z sections, facets are stacked in y
1266    o pkg/thsice:
1267       - change a few routines for better vectorization: thsice_albedo.F,
1268         thsice_step_temp.F, and in thsice_calc_thickn.F. Results are
1269         not affected, but in particular the latter routine has changed
1270         dramatically (not necessarily easier to read now).
1271       - re-arrange calculation in THSICE_SOLVE4TEMP: move outside of i,j loops
1272       iteration loop and call to S/R THSICE_GET_BULKF & THSICE_GET_EXF.
1273    o verification/lab_sea:
1274      - overhaul of the forward model experiments. The main motivation
1275        for this revision is that lab_sea has proven quite fragile (when
1276        changing the sea-ice code, and switching platforms) to a point
1277        when failures were very hard to attribute to specific code problems.
1278      - the suspected reason for this fragility is noise amplification by evp so,
1279        to start with, we decided to replace evp with lsr in the main experiment.
1280      - the input.lsr experiment thus became obsolete and was removed.
1281      - it was replaced with the input.fd experiment that uses an
1282        analytical "free drift" solution as the ice velocity field.
1283      - Taken together, input (lsr), input.fd (free drift) and input.hb87 (evp)
1284        will hopefully allow us to discriminate problems due to dynamic solvers
1285        from problems due to the thermodynamic code. input.salt_plume (lsr) allows
1286        us to test additional options, along with the salt plume package.
1287      - Finally a pickup was generated (at the end of a one year run) to
1288        make the tests more representative of an actual model run. Previously
1289        the tests starting point was a 1m thickness of ice everywhere.
1290    o pkg/seaice:
1291      - introducing S\R seaice_freedrift.F that compute the
1292        analytical solution to an approximate ice momentum
1293        equation (i.e. the simple stress/coriolis balance).
1294      - define SEAICE_ALLOW_FREEDRIFT to trigger the computation
1295        of the free drift velocity field, and enable its use.
1296        To actually use the free drift solution as the model ice
1297        velocity field set SEAICEuseFREEDRIFT to .TRUE. in data.seaice.
1298    o move "useOASIS" from PARAMS.h to EEPARAMS.h and read it from "eedata"
1299    
1300    checkpoint62l (2010/10/04)
1301    o pkg/seaice:
1302      -fix the USE_ORIGINAL_SBI version (for variable freezing point);
1303      -use "celsius2K" in SEAICE_VARIABLE_FREEZING_POINT and in new
1304       version (with USE_ORIGINAL_SBI undef);
1305    o add hooks for new packages OASIS, the package will follow
1306      (hooks exclude the seaice pkg for now)
1307    o pkg/autodiff: ALLOW_AUTODIFF_WHTAPEIO
1308      Option to use mdsio_read_whalos.F/mdsio_write_whalos.F,
1309      rather than mdsio_readvector.F/mdsio_writevector.F, within
1310      adread_adwrite.F to read/write adjoint-related tapes to disk.
1311    o eesupp and pkg/mdsio: ALLOW_WHIO
1312      Option to write/read 2D fields to files including tiles halos.
1313      The main purpose is for adjoint related "tape I/O".
1314      The secondary purpose is for debugging phases.
1315      A word on those rather specifically intended purposes.
1316      The code was meant to be stripped down to the bare minimum.
1317      Typically, there is a unique and basic mapping to the global
1318      buffer (tile by tile, then proc by proc, then level by level), and
1319      byteswaps and meta-files are omitted. Indeed the (*_WH*) code is not
1320      meant to generate user friendly outputs of various shapes and forms.
1321      Rather it is intended, for the knowledgeabale developers,
1322      to be largely independent of the many mdsio options, to allow
1323      outputs of tiles+halos in debugging phases and in adjoint runs,
1324      and to allow some flexibility in tuning (adoint) I/O depending on each
1325      file system behavior. With regard to tuning, most of the potential knobs
1326      (to leave files open, to allocate the I/O indep. of usesinglecpuio,
1327      to specify directories, to specify the typical size of I/O calls, etc.)
1328      are not yet included, and will be added if they prove useful.
1329    o pkg/seaice:
1330       fix uninitialised arrays in USE_ORIGINAL_SBI version of seaice_solve4temp.F
1331    o pkg/seaice:
1332       new S/R seaice_solve4temp.F: this is the merged version of Ian Fenty
1333       code (seaice_budget_ice_if.F) which enable to recover old standard
1334       code (seaice_budget_ice.F) when option USE_ORIGINAL_SBI is defined.
