5      ==============================      ==============================
6    
7    o pkg/diagnostics/diagstats_calc.F: add special code for TARGET_NEC_SX
8      that vectorises. This code uses 3 extra 2D fields, F90 array assignments
9      and F90 intrinsic routines SUM, MINVAL, MAXVAL, but since TARGET_NEC_SX
10      does not even come with an F77 compiler anymore, this should not be
11      a limitation
12    
13    checkpoint63e (2011/11/06)
14    o pkg/seaice adjoint of LSR:
15      - substantially rework STORE dirs.
16      - add new flag SEAICE_LSR_ADJOINT_ITER and parameter SOLV_MAX_FIXED
17        this flag will do SOLV_MAX_ITERS but only store SOLV_MAX_FIXED fields
18        and only perform SOLV_MAX_FIXED adjoint iters.
19        If flag SEAICE_LSR_ADJOINT_ITER is undef-ined, the store in the iteration
20        always goes to same record, meaning that the last forward field will be
21        the one used in the adjoint - an approximation.
22      - now produces non-zero LSR-related gradients, and acceptable gradients for
23        An's zonal (x-z) test case (to be checked in)
24      - lab_sea: produces acceptable gradients for lab_sea with forward/backward LSR
25        (but these are screwed up by the thermodynamics in the first place);
26        reduce from 4 to 3 timesteps to avoid t.d. issue as temporary solution;
27        output_adm.txt also reflects changes to seaice_lsr
28      - global_ocean.cs32x15:
29        * the "default" input_ad.seaice has been re-defined to always exclude dynamics
30          (output_adm.seaice.txt was updated)
31        * new input_ad.seaice_dynmix tests a forward LSR / backward free-drift
32          (output_adm.seaice_dynmix.txt)
33    o test-exp. exp4+stevens:
34      - switch off pTracers and nonHydrostatic (restart problems with NH); update output
35    o pkg/seaice (lsr solver):
36      - put coriolis term into FORCEX,Y (as in seaice_evp.F; previously in rhsU,V only);
37        update output (change truncation) of FWD test exp lab_sea & global_ocean.cs32x15
38      - fix SEAICEuseFREEDRIFT for new OBCS version (ndef OBCS_UVICE_OLD)
39      - new parameter "LSR_mixIniGuess" allows (if=2,4) to mix free-drift solution
40        into initial guess for linearised solver; use weight ~ (1/err)^2,4.
41      - compute (with new S/R) and print initial (+ free-driff sol. if available)
42        and final residual of linearised system.
43    o pkg/pp81: add diagnostics for vertical eddy viscosity and diffusivity
44      (requires new subroutines pp81_init_fixed.F/pp81_diagnostics_init.F)
45    o pkg/obcs: Stevens BCs (still only for east and west)
46      - fix Stevens BCs by using intermediate velocities of previous
47        time step as "baroclinic" contribution rather velocity of one grid cell
48        inside the boundaries; more consistent but makes the entire treatment
49        more complicated, requires new pickup files and two new S/Rs:
50        obcs_copy_uv_n and obcs_save_uv_n
51        keep old version with flag OBCS_STEVENS_USE_INTERIOR_VELOCITY
52        (undefined by default)
53      - silently move computation of some grid factors into separate loops to
54        save some recomputations
55      - add a hack for non-linear free surface
56      - add a verification experiment to exp4 that tests this code
57    o make gluemnc/xplodemnc work with (moron) non-GNU shell tools
58    
59    checkpoint63d (2011/10/25)
60    o pkg/obcs + seaice-dynamics:
61      - new implementation calls OBCS_APPLY_UVICE (in seaice_dynsolver.F) before
62        solving for uIce,vIce and prevent SEAICE_LSR or SEAICE_EVP to modify OB
63        values (consistent with an implicit method).
64      - add option OBCS_UVICE_OLD (in OBCS_OPTIONS.h, defined by default) to
65        return to older implementation (same results as before); note that none of
66        the "experimental" OBCS_SEAICE options are implemented in the new version.
67      - switch test exp. seaice_obcs to use new version (update output).
68    o pkg/seaice:
69      - add few stop (B-grid & CS-exch, B-grid & obcs, AUTODIFF & SEAICE_maskRHS)
70      - add parenthesis in Water-Ice drag calculations (evp & lsr);
71      - in seaice_lsr.F, simplify and fix AA3 setting in case sNx or sNy=1;
72        and fix case SEAICE_waterDrag=0 (but unstable if no or little seaice)
73      - update output of test exp lab_sea that uses evp or lsr (fwd+ad)
74        and global_ocean.cs32x15 (icedyn & seaice fwd+ad).
75    o pkg/layers:
76      - Include potential density as new coordinate (Thanks to David Munday)
77    o pkg/dic:
78      - Remove subroutine CALC_PCO2_APPROX_CO3 from carbon_chem.F and add
79        carbonate computation/output to CALC_PCO2_APPROX
80    o pkg/generic_advdiff
81      - make TAF generate code that vectorizes:
82        gad_dst3fl_adv_*.F, gad_u3c4_impl_r.F
83    o model/src:
84      - improve vectorization also for adjoint code of
85        solve_tridiagonal and solve_pentadiagonal. As this requires up to
86        5 new 3D-fields, this code is only turned on for the combination of
87        ALLOW_AUTODIFF_TAMC and TARGET_NEC_SX. Also remove error message
88        for singular matrix check (only for TARGET_NEC_SX).
89      - remove hard-wiring of CPP-flag ALLOW_SOLVERS_KLOOPINSIDE to
90        ALLOW_AUTODIFF. This flag now needs to be set outside of
91        solve_tri/pentadiagonal.F
92    o pkg/exf:
93      - fix previous modif in exf_readparms.F (revision 1.66: treatment of
94        optional namelist EXF_NML_OBCS).
95      - add many debug-print (to trace down where pkg/cal error msg comes from)
96    o pkg/mom_vecinv/mom_vi_hdissip.F
97      - rearrange loops so that vectorization is improved and in particular
98        the adjoint routine vectorizes. The code is a little longer now, but I
99        think easier to read.
100        Note: CPP-flag MOM_VI_ORIGINAL_VISCA4 is not tested.
101    o pkg/seaice:
102      - allow to specify initial seaice velocity from files (uIceFile,vIceFile)
103    o pkg/exch2:
104      - alternative code (without tile x tile matrix) for cumulated (global) sum;
105        used as default; keep using matrix version in adjustment.cs-32x32x1.
106    o tools/build_options:
107      - after merging some MPI and/or multi-threads specific optfiles so that
108        the modified default optfile support both built (using genmake2 -mpi
109        for the MPI built, using genmake2 -omp for OpenMP built),
110        move now obsolete optfiles to tools/build_options/unsupported/
111       (add copy of email sent to support list in doc/optfiles_changes.txt)
112    
113    checkpoint63c (2011/09/28)
114    o pkg/ebm:
115      - fix ebm_zonalmean.F for several procs in Ydir (nPy > 1); update output of
116        test exp. global_ocean_ebm (affects machine truncation, 12 digits for cg2d)
117    o pkg/seaice (SItracer pickup)
118    * Simple code for pickup of SItracer fields (#define ALLOW_SITRACER)
119      To be done:
120      - thorough testing of missing fields in S/R seaice_read_pickup
121      - thorough matching between generic tracers and specific fields used
122        (e.g. volume-weighted age, area-weighted age, salinity, ...)
123    o pkg/grdchk:
124      - all procs calculate and print finite-difference gradient (for testreport)
125      - change description output used by testreport;
126      - AD testing: also compare and report Finite-difference gradient;
127        => update all output_adm*.txt
128    o test exp. global_ocean_ebm:
129      - switch back useRealFreshWaterFlux (no problem anymore with run-off);
130        and turn on exactConserve; update (fwd) output.
131    o pkg/seaice (LSR):
132      - print to STDOUT number of solver iterations at SEAICE_monFreq interval.
133      - modify solver to deal cleanly with u/v switch at face edges (CS-grid):
134        * identical results with non-CS topology (but save up to half of EXCH calls)
135        * no much changes in cs-32 verification tests since no ice at face edges
136         (differences due to convergence criteria, since nb of iterations changed)
137        * expect some differences on lat-lon-cap grid.
138        update FWD results of global_ocean.cs32x15 test exp. (icedyn & seaice)
139    o pkg/exch2:
140      - add new CPP option to disable Cumul-Sum matrix (to save storage when using
141        many tiles); until alternative coding is added, just add a stop.
142    o pkg/kpp:
143      - move ptracer/salt correction to KPP diffusivity from calc_3d_diffusivity.F
144        to S/R KPP_CALC_DIFF_PTR (+ add tracer-index to argument list).
145    o optfiles:
146      - merged few MPI specific (*+mpi*) and multi-threads specific (*+mth) optfiles
147        into corresponding standard one, which now support different build:
148        (when using "genmake2 -mpi" for MPI built, "genmake2 -omp" for OpenMP built)
149      - add "darwin_amd64_gfortran" optfile (initially from Constantinos, tested by Gael)
150    o pkg/obcs (seaice):
151      - add missing EXCH for uIce,vIce after applying OBCS;
152      - remove S/R EXF_SWAPFFIELDS_X/Y , disable S/R EXF_SET_OBCS_X/Y by adding
153        argument = number of levels to S/R EXF_SWAPFFIELDS_XZ/YZ and S/R
154        EXF_SET_OBCS_XZ/YZ ; update obcs_exf_load.F;
155      - fix EXF_SET_OBCS_XZ/YZ for multi-threaded (assuming loaded arrays are shared)
156      - verification exp. seaice_obcs: split domain in 2 tiles ; add SIZE.h_mpi

160      - use buffer for floats IO (trajectories & profiles); size set in FLT_SIZE.h;
161      - fix pickup and trajectories + profiles output with multi-threads;
162      - add parameter to select group of fields to write along trajectory and
163        profile (default unchanged);
164      - only call PORT_RAND* function when flt_noise <> 0;
165      - add multi-threaded test for verification exp. flt_example.
166    o eesupp/src:
167      - fix S/R ALL_PROC_DIE for MPI+multi-threads.
168      - USE_OMP_THREADING: check that number of threads (from eedata) matches
169        actual number (from env.var. setting).
170    o pkg/ebm:
171      - fix multi-threading in ebm_area_t.F ; clean-up EBM.h header file.
172      - add multi-threaded test for verification exp. global_ocean_ebm

174    checkpoint63b (2011/08/29)
175    o pkg/ebm:
176      - fix sign of runoff;
177      - update directly forcing fields (Qnet,EmPmR) to use standard
178        external_forcing_surf.F (remove ebm_forcing_surf.F);
179      - avoid loading forcing fields a 2nd time (1rst time from ini_forcing.F);
180      - set either tauThetaClimRelax (in data) or tauThetaZonRelax (in data.ebm)
181        and apply relaxation towards corresponding SST field (2-D map or ZonAver).
182      - update global_ocean_ebm parameters file data and update output (fwd+ad).
183    o verification/matrix_example:

190      - use standard DIFFERENT_MULTIPLE function;
191      - add MATRIX_OPTIONS.h
192    o verification/matrix_example:
193       To allow to split the domain in several tiles, change the domain size
194        from 31x31 to 32x32 by adding 1 row (on Southern side) + 1 column (on
195        Western side) of land points.
196    o (*_)write_pickup:
197      - fix few bugs in mypackage_read/write_pickup.F
198      - in MDS_WR_METAFILES calls, replace "myTime" by a local copy into

201      - fix initialisation of main diagonal matrix (for overlap values)
202    o tools/build_options:
203      - towards single optfile for MPI and non-MPI built: merge few +mpi optfile

208        and use "-devel" testreport option for standard testing on baudelaire.
209    o pkg/grdchk:
210      - Assume that all gradient-check position are within the same tile
