5      ==============================      ==============================
6    
7    o pkg/seaice/seaice_init_varia.F
8      - undo resetting UVM=0 that has slipped in unnoticed in r1.49 and
9        caused zero ice-velocities for the B-grid code
10    o pkg/seaice/seaice_init_fixed.F
11      - fix a bug in the initialisation of the second metric terms
12        k2AtC and k2AtZ: k2AtC was set to the value of k2AtZ and k2AtZ was 0.
13      - this affects all seaice configurations with useCurviLinearGrid = .true.
14        and SEAICEuseDynamics = .true. (default) and SEAICEuseMetricTerms
15        = .true. (default)
16      - the only verification experiment affected is global_ocean.cs32x15:
17        icedyn, seaice, and seaice_dynmix (AD)
18    o pkg/thsice/thsice_diagnostics_state.F
19      - only for TARGET_NEC_SX: initialise all of tmpFld, so that overlap does
20        not contain garbage that can lead to surprises in diagstats_calc.F
21    o model/src:
22      - move bi,bj loops inside INTEGR_CONTINUITY ;
23      - call INTEGR_CONTINUITY directly from forward_step.F
24        (previously called from momentum_correction_step.F)
25      - call UPDATE_ETAH from integr_continuity.F and update initialise_varia.F,
26        forward_step.F and pkg/ecco/the_main_loop.F
27    o model/src/do_oceanic_phys.F:
28      - reset addMass to zero only if useICEFRONT ;
29      - separated k-loop for rhoInSitu calculation ;
30      - add 2 diagnostics for wVel*delta^k(Rho) at constant pressure (= WdRHO_P)
31        and at constant T,S (= WdRHOdP);
32      NOTE: change diagnostics WRHOMASS : this is now simply the Vertical transport
33        of In-Situ Density (Anomaly) (=wVel*rho^bar-k) (previously was Vertical
34        transport of locally-referenced potential density);
35        to recover old diag: (WRHOMASS)_old = (WRHOMASS)_new -1/2 * (WdRHOdP)
36    o gluemnc:
37      - replace ncrcat with ncks when adding variables to *.glob.nc
38      - change the way variables without record dimensions are handled so that
39        files that have variables with and without record variables can be glued:
40        add a record dimension with a new unique name to be able to differentiate
41        between variable with and without a-prior record dimensions. Remove
42        this record dimension before adding the variable to the *.glob.nc file.
43        This procedure automatically works also for grid.*.nc files that do not
44        have any record dimension.
45    o verification/cpl_aim+ocn:
46      - generate new reference output on baudelaire (gfortran, mpich2) (previously
47        from old aces-grid cluster, ao + ifort) and update 'run_cpl_test' script.
48    o pkg/obcs/obcs_calc_stevens.F:
49      - add code for northern and southern boundaries.
50      - reorder some loops to save some operations and so that drFBar can be scalar
51    o model/src:
52      - re-arrange extrapolation calculation in Adams-Bashforth S/R (affects machine
53        truncation) and add diagnostics for Adams-Bashforth tendency increment.
54      - update test-exp. AD output:
55        1D_ocean_ice_column, bottom_ctrl_5x5, lab_sea.noseaicedyn, obcs_ctrl;
56      and FWD output: exp4 (x3), fizhi-cs-32x32x40, fizhi-cs-aqualev20,
57        front_relax (x3), global_ocean.90x40x15 (x2), global_ocean.cs32x15 (x5),
58        global_ocean_ebm, ideal_2D_oce, internal_wave, isomip (x3), lab_sea (x4),
59        matrix_example, MLAdjust (x5), natl_box (x2), tutorial_advection_in_gyre,
60        tutorial_global_oce_in_p, tutorial_global_oce_latlon and
61        tutorial_plume_on_slope.
62    o pkg/diagnostics/diagstats_calc.F: add special code for TARGET_NEC_SX
63      that vectorises. This code uses 3 extra 2D fields, F90 array assignments
64      and F90 intrinsic routines SUM, MINVAL, MAXVAL, but since TARGET_NEC_SX
65      does not even come with an F77 compiler anymore, this should not be
66      a limitation
67    
68    checkpoint63e (2011/11/06)
69    o pkg/seaice adjoint of LSR:
70      - substantially rework STORE dirs.
71      - add new flag SEAICE_LSR_ADJOINT_ITER and parameter SOLV_MAX_FIXED
72        this flag will do SOLV_MAX_ITERS but only store SOLV_MAX_FIXED fields
73        and only perform SOLV_MAX_FIXED adjoint iters.
74        If flag SEAICE_LSR_ADJOINT_ITER is undef-ined, the store in the iteration
75        always goes to same record, meaning that the last forward field will be
76        the one used in the adjoint - an approximation.
77      - now produces non-zero LSR-related gradients, and acceptable gradients for
78        An's zonal (x-z) test case (to be checked in)
79      - lab_sea: produces acceptable gradients for lab_sea with forward/backward LSR
80        (but these are screwed up by the thermodynamics in the first place);
81        reduce from 4 to 3 timesteps to avoid t.d. issue as temporary solution;
82        output_adm.txt also reflects changes to seaice_lsr
83      - global_ocean.cs32x15:
84        * the "default" input_ad.seaice has been re-defined to always exclude dynamics
85          (output_adm.seaice.txt was updated)
86        * new input_ad.seaice_dynmix tests a forward LSR / backward free-drift
87          (output_adm.seaice_dynmix.txt)
88    o test-exp. exp4+stevens:
89      - switch off pTracers and nonHydrostatic (restart problems with NH); update output
90    o pkg/seaice (lsr solver):
91      - put coriolis term into FORCEX,Y (as in seaice_evp.F; previously in rhsU,V only);
92        update output (change truncation) of FWD test exp lab_sea & global_ocean.cs32x15
93      - fix SEAICEuseFREEDRIFT for new OBCS version (ndef OBCS_UVICE_OLD)
94      - new parameter "LSR_mixIniGuess" allows (if=2,4) to mix free-drift solution
95        into initial guess for linearised solver; use weight ~ (1/err)^2,4.
96      - compute (with new S/R) and print initial (+ free-driff sol. if available)
97        and final residual of linearised system.
98    o pkg/pp81: add diagnostics for vertical eddy viscosity and diffusivity
99      (requires new subroutines pp81_init_fixed.F/pp81_diagnostics_init.F)
100    o pkg/obcs: Stevens BCs (still only for east and west)
101      - fix Stevens BCs by using intermediate velocities of previous
102        time step as "baroclinic" contribution rather velocity of one grid cell
103        inside the boundaries; more consistent but makes the entire treatment
104        more complicated, requires new pickup files and two new S/Rs:
105        obcs_copy_uv_n and obcs_save_uv_n
106        keep old version with flag OBCS_STEVENS_USE_INTERIOR_VELOCITY
107        (undefined by default)
108      - silently move computation of some grid factors into separate loops to
109        save some recomputations
110      - add a hack for non-linear free surface
111      - add a verification experiment to exp4 that tests this code
112    o make gluemnc/xplodemnc work with (moron) non-GNU shell tools
113    
114    checkpoint63d (2011/10/25)
115    o pkg/obcs + seaice-dynamics:
116      - new implementation calls OBCS_APPLY_UVICE (in seaice_dynsolver.F) before
117        solving for uIce,vIce and prevent SEAICE_LSR or SEAICE_EVP to modify OB
118        values (consistent with an implicit method).
119      - add option OBCS_UVICE_OLD (in OBCS_OPTIONS.h, defined by default) to
120        return to older implementation (same results as before); note that none of
121        the "experimental" OBCS_SEAICE options are implemented in the new version.
122      - switch test exp. seaice_obcs to use new version (update output).
123    o pkg/seaice:
124      - add few stop (B-grid & CS-exch, B-grid & obcs, AUTODIFF & SEAICE_maskRHS)
125      - add parenthesis in Water-Ice drag calculations (evp & lsr);
126      - in seaice_lsr.F, simplify and fix AA3 setting in case sNx or sNy=1;
127        and fix case SEAICE_waterDrag=0 (but unstable if no or little seaice)
128      - update output of test exp lab_sea that uses evp or lsr (fwd+ad)
129        and global_ocean.cs32x15 (icedyn & seaice fwd+ad).
130    o pkg/layers:
131      - Include potential density as new coordinate (Thanks to David Munday)
132    o pkg/dic:
133      - Remove subroutine CALC_PCO2_APPROX_CO3 from carbon_chem.F and add
134        carbonate computation/output to CALC_PCO2_APPROX
135    o pkg/generic_advdiff
136      - make TAF generate code that vectorizes:
137        gad_dst3fl_adv_*.F, gad_u3c4_impl_r.F
138    o model/src:
139      - improve vectorization also for adjoint code of
140        solve_tridiagonal and solve_pentadiagonal. As this requires up to
141        5 new 3D-fields, this code is only turned on for the combination of
142        ALLOW_AUTODIFF_TAMC and TARGET_NEC_SX. Also remove error message
143        for singular matrix check (only for TARGET_NEC_SX).
144      - remove hard-wiring of CPP-flag ALLOW_SOLVERS_KLOOPINSIDE to
145        ALLOW_AUTODIFF. This flag now needs to be set outside of
146        solve_tri/pentadiagonal.F
147    o pkg/exf:
148      - fix previous modif in exf_readparms.F (revision 1.66: treatment of
149        optional namelist EXF_NML_OBCS).
150      - add many debug-print (to trace down where pkg/cal error msg comes from)
151    o pkg/mom_vecinv/mom_vi_hdissip.F
152      - rearrange loops so that vectorization is improved and in particular
153        the adjoint routine vectorizes. The code is a little longer now, but I
154        think easier to read.
155        Note: CPP-flag MOM_VI_ORIGINAL_VISCA4 is not tested.
156    o pkg/seaice:
157      - allow to specify initial seaice velocity from files (uIceFile,vIceFile)
158    o pkg/exch2:
159      - alternative code (without tile x tile matrix) for cumulated (global) sum;
160        used as default; keep using matrix version in adjustment.cs-32x32x1.
161    o tools/build_options:
162      - after merging some MPI and/or multi-threads specific optfiles so that
163        the modified default optfile support both built (using genmake2 -mpi
164        for the MPI built, using genmake2 -omp for OpenMP built),
165        move now obsolete optfiles to tools/build_options/unsupported/
166       (add copy of email sent to support list in doc/optfiles_changes.txt)
167    
168    checkpoint63c (2011/09/28)
169    o pkg/ebm:
170      - fix ebm_zonalmean.F for several procs in Ydir (nPy > 1); update output of
171        test exp. global_ocean_ebm (affects machine truncation, 12 digits for cg2d)
172    o pkg/seaice (SItracer pickup)
173    * Simple code for pickup of SItracer fields (#define ALLOW_SITRACER)
174      To be done:
175      - thorough testing of missing fields in S/R seaice_read_pickup
176      - thorough matching between generic tracers and specific fields used
177        (e.g. volume-weighted age, area-weighted age, salinity, ...)
178    o pkg/grdchk:
179      - all procs calculate and print finite-difference gradient (for testreport)
180      - change description output used by testreport;
181      - AD testing: also compare and report Finite-difference gradient;
182        => update all output_adm*.txt
183    o test exp. global_ocean_ebm:
184      - switch back useRealFreshWaterFlux (no problem anymore with run-off);
185        and turn on exactConserve; update (fwd) output.
186    o pkg/seaice (LSR):
187      - print to STDOUT number of solver iterations at SEAICE_monFreq interval.
188      - modify solver to deal cleanly with u/v switch at face edges (CS-grid):
189        * identical results with non-CS topology (but save up to half of EXCH calls)
190        * no much changes in cs-32 verification tests since no ice at face edges
191         (differences due to convergence criteria, since nb of iterations changed)
192        * expect some differences on lat-lon-cap grid.
193        update FWD results of global_ocean.cs32x15 test exp. (icedyn & seaice)
194    o pkg/exch2:
195      - add new CPP option to disable Cumul-Sum matrix (to save storage when using
196        many tiles); until alternative coding is added, just add a stop.
197    o pkg/kpp:
198      - move ptracer/salt correction to KPP diffusivity from calc_3d_diffusivity.F
199        to S/R KPP_CALC_DIFF_PTR (+ add tracer-index to argument list).
200    o optfiles:
201      - merged few MPI specific (*+mpi*) and multi-threads specific (*+mth) optfiles
202        into corresponding standard one, which now support different build:
203        (when using "genmake2 -mpi" for MPI built, "genmake2 -omp" for OpenMP built)
204      - add "darwin_amd64_gfortran" optfile (initially from Constantinos, tested by Gael)
205    o pkg/obcs (seaice):
206      - add missing EXCH for uIce,vIce after applying OBCS;
207      - remove S/R EXF_SWAPFFIELDS_X/Y , disable S/R EXF_SET_OBCS_X/Y by adding
208        argument = number of levels to S/R EXF_SWAPFFIELDS_XZ/YZ and S/R
209        EXF_SET_OBCS_XZ/YZ ; update obcs_exf_load.F;
210      - fix EXF_SET_OBCS_XZ/YZ for multi-threaded (assuming loaded arrays are shared)
211      - verification exp. seaice_obcs: split domain in 2 tiles ; add SIZE.h_mpi
212        and eedata.mth for MPI and mutlti-threaded testing.
213    o pkg/flt:
214      - make FLT EXCH working with multi-threads (and MPI + multi-threads);
215      - use buffer for floats IO (trajectories & profiles); size set in FLT_SIZE.h;
216      - fix pickup and trajectories + profiles output with multi-threads;
217      - add parameter to select group of fields to write along trajectory and
218        profile (default unchanged);
219      - only call PORT_RAND* function when flt_noise <> 0;
220      - add multi-threaded test for verification exp. flt_example.
221    o eesupp/src:
222      - fix S/R ALL_PROC_DIE for MPI+multi-threads.
223      - USE_OMP_THREADING: check that number of threads (from eedata) matches
224        actual number (from env.var. setting).
225  o pkg/ebm:  o pkg/ebm:
226    - fix multi-threading in ebm_area_t.F ; clean-up EBM.h header file.    - fix multi-threading in ebm_area_t.F ; clean-up EBM.h header file.
227    - add multi-threaded test for verification exp. global_ocean_ebm    - add multi-threaded test for verification exp. global_ocean_ebm
