6    
7    checkpoint63f (2011/11/30)
8    o pkg/obcs/obcs_calc_stevens.F:
9      - join some loops to reduce number of if-statements
10      - fix a bug in code for northern and southern boundaries.
11    o pkg/seaice/seaice_init_varia.F
12      - undo resetting UVM=0 that has slipped in unnoticed in r1.49 and
13        caused zero ice-velocities for the B-grid code
14    o pkg/seaice/seaice_init_fixed.F
15      - fix a bug in the initialisation of the second metric terms
16        k2AtC and k2AtZ: k2AtC was set to the value of k2AtZ and k2AtZ was 0.
17      - this affects all seaice configurations with useCurviLinearGrid = .true.
18        and SEAICEuseDynamics = .true. (default) and SEAICEuseMetricTerms
19        = .true. (default)
20      - the only verification experiment affected is global_ocean.cs32x15:
21        icedyn, seaice, and seaice_dynmix (AD)
22    o pkg/thsice/thsice_diagnostics_state.F
23      - only for TARGET_NEC_SX: initialise all of tmpFld, so that overlap does
24        not contain garbage that can lead to surprises in diagstats_calc.F
25    o model/src:
26      - move bi,bj loops inside INTEGR_CONTINUITY ;
27      - call INTEGR_CONTINUITY directly from forward_step.F
28        (previously called from momentum_correction_step.F)
29      - call UPDATE_ETAH from integr_continuity.F and update initialise_varia.F,
30        forward_step.F and pkg/ecco/the_main_loop.F
31    o model/src/do_oceanic_phys.F:
32      - reset addMass to zero only if useICEFRONT ;
33      - separated k-loop for rhoInSitu calculation ;
34      - add 2 diagnostics for wVel*delta^k(Rho) at constant pressure (= WdRHO_P)
35        and at constant T,S (= WdRHOdP);
36      NOTE: change diagnostics WRHOMASS : this is now simply the Vertical transport
37        of In-Situ Density (Anomaly) (=wVel*rho^bar-k) (previously was Vertical
38        transport of locally-referenced potential density);
39        to recover old diag: (WRHOMASS)_old = (WRHOMASS)_new -1/2 * (WdRHOdP)
40    o gluemnc:
41      - replace ncrcat with ncks when adding variables to *.glob.nc
42      - change the way variables without record dimensions are handled so that
43        files that have variables with and without record variables can be glued:
44        add a record dimension with a new unique name to be able to differentiate
45        between variable with and without a-prior record dimensions. Remove
46        this record dimension before adding the variable to the *.glob.nc file.
47        This procedure automatically works also for grid.*.nc files that do not
48        have any record dimension.
49    o verification/cpl_aim+ocn:
50      - generate new reference output on baudelaire (gfortran, mpich2) (previously
51        from old aces-grid cluster, ao + ifort) and update 'run_cpl_test' script.
52    o pkg/obcs/obcs_calc_stevens.F:
53      - add code for northern and southern boundaries.
54      - reorder some loops to save some operations and so that drFBar can be scalar
55    o model/src:
56      - re-arrange extrapolation calculation in Adams-Bashforth S/R (affects machine
57        truncation) and add diagnostics for Adams-Bashforth tendency increment.
58      - update test-exp. AD output:
59        1D_ocean_ice_column, bottom_ctrl_5x5, lab_sea.noseaicedyn, obcs_ctrl;
60      and FWD output: exp4 (x3), fizhi-cs-32x32x40, fizhi-cs-aqualev20,
61        front_relax (x3), global_ocean.90x40x15 (x2), global_ocean.cs32x15 (x5),
62        global_ocean_ebm, ideal_2D_oce, internal_wave, isomip (x3), lab_sea (x4),
63        matrix_example, MLAdjust (x5), natl_box (x2), tutorial_advection_in_gyre,
64        tutorial_global_oce_in_p, tutorial_global_oce_latlon and
65        tutorial_plume_on_slope.
66    o pkg/diagnostics/diagstats_calc.F: add special code for TARGET_NEC_SX
67      that vectorises. This code uses 3 extra 2D fields, F90 array assignments
68      and F90 intrinsic routines SUM, MINVAL, MAXVAL, but since TARGET_NEC_SX
69      does not even come with an F77 compiler anymore, this should not be
70      a limitation
71    
72    checkpoint63e (2011/11/06)
73    o pkg/seaice adjoint of LSR:
74      - substantially rework STORE dirs.
75      - add new flag SEAICE_LSR_ADJOINT_ITER and parameter SOLV_MAX_FIXED
76        this flag will do SOLV_MAX_ITERS but only store SOLV_MAX_FIXED fields
77        and only perform SOLV_MAX_FIXED adjoint iters.
78        If flag SEAICE_LSR_ADJOINT_ITER is undef-ined, the store in the iteration
79        always goes to same record, meaning that the last forward field will be
80        the one used in the adjoint - an approximation.
81      - now produces non-zero LSR-related gradients, and acceptable gradients for
82        An's zonal (x-z) test case (to be checked in)
83      - lab_sea: produces acceptable gradients for lab_sea with forward/backward LSR
84        (but these are screwed up by the thermodynamics in the first place);
85        reduce from 4 to 3 timesteps to avoid t.d. issue as temporary solution;
86        output_adm.txt also reflects changes to seaice_lsr
87      - global_ocean.cs32x15:
88        * the "default" input_ad.seaice has been re-defined to always exclude dynamics
89          (output_adm.seaice.txt was updated)
90        * new input_ad.seaice_dynmix tests a forward LSR / backward free-drift
91          (output_adm.seaice_dynmix.txt)
92    o test-exp. exp4+stevens:
93      - switch off pTracers and nonHydrostatic (restart problems with NH); update output
94    o pkg/seaice (lsr solver):
95      - put coriolis term into FORCEX,Y (as in seaice_evp.F; previously in rhsU,V only);
96        update output (change truncation) of FWD test exp lab_sea & global_ocean.cs32x15
97      - fix SEAICEuseFREEDRIFT for new OBCS version (ndef OBCS_UVICE_OLD)
98      - new parameter "LSR_mixIniGuess" allows (if=2,4) to mix free-drift solution
99        into initial guess for linearised solver; use weight ~ (1/err)^2,4.
100      - compute (with new S/R) and print initial (+ free-driff sol. if available)
101        and final residual of linearised system.
102    o pkg/pp81: add diagnostics for vertical eddy viscosity and diffusivity
103      (requires new subroutines pp81_init_fixed.F/pp81_diagnostics_init.F)
104    o pkg/obcs: Stevens BCs (still only for east and west)
105      - fix Stevens BCs by using intermediate velocities of previous
106        time step as "baroclinic" contribution rather velocity of one grid cell
107        inside the boundaries; more consistent but makes the entire treatment
108        more complicated, requires new pickup files and two new S/Rs:
109        obcs_copy_uv_n and obcs_save_uv_n
110        keep old version with flag OBCS_STEVENS_USE_INTERIOR_VELOCITY
111        (undefined by default)
112      - silently move computation of some grid factors into separate loops to
113        save some recomputations
114      - add a hack for non-linear free surface
115      - add a verification experiment to exp4 that tests this code
116    o make gluemnc/xplodemnc work with (moron) non-GNU shell tools
117    
118    checkpoint63d (2011/10/25)
119    o pkg/obcs + seaice-dynamics:
120      - new implementation calls OBCS_APPLY_UVICE (in seaice_dynsolver.F) before
121        solving for uIce,vIce and prevent SEAICE_LSR or SEAICE_EVP to modify OB
122        values (consistent with an implicit method).
123      - add option OBCS_UVICE_OLD (in OBCS_OPTIONS.h, defined by default) to
124        return to older implementation (same results as before); note that none of
125        the "experimental" OBCS_SEAICE options are implemented in the new version.
126      - switch test exp. seaice_obcs to use new version (update output).
127    o pkg/seaice:
128      - add few stop (B-grid & CS-exch, B-grid & obcs, AUTODIFF & SEAICE_maskRHS)
129      - add parenthesis in Water-Ice drag calculations (evp & lsr);
130      - in seaice_lsr.F, simplify and fix AA3 setting in case sNx or sNy=1;
131        and fix case SEAICE_waterDrag=0 (but unstable if no or little seaice)
132      - update output of test exp lab_sea that uses evp or lsr (fwd+ad)
133        and global_ocean.cs32x15 (icedyn & seaice fwd+ad).
134    o pkg/layers:
135      - Include potential density as new coordinate (Thanks to David Munday)
136    o pkg/dic:
137      - Remove subroutine CALC_PCO2_APPROX_CO3 from carbon_chem.F and add
138        carbonate computation/output to CALC_PCO2_APPROX
139    o pkg/generic_advdiff
140      - make TAF generate code that vectorizes:
141        gad_dst3fl_adv_*.F, gad_u3c4_impl_r.F
142    o model/src:
143      - improve vectorization also for adjoint code of
144        solve_tridiagonal and solve_pentadiagonal. As this requires up to
145        5 new 3D-fields, this code is only turned on for the combination of
146        ALLOW_AUTODIFF_TAMC and TARGET_NEC_SX. Also remove error message
147        for singular matrix check (only for TARGET_NEC_SX).
148      - remove hard-wiring of CPP-flag ALLOW_SOLVERS_KLOOPINSIDE to
149        ALLOW_AUTODIFF. This flag now needs to be set outside of
150        solve_tri/pentadiagonal.F
151    o pkg/exf:
152      - fix previous modif in exf_readparms.F (revision 1.66: treatment of
153        optional namelist EXF_NML_OBCS).
154      - add many debug-print (to trace down where pkg/cal error msg comes from)
155    o pkg/mom_vecinv/mom_vi_hdissip.F
156      - rearrange loops so that vectorization is improved and in particular
157        the adjoint routine vectorizes. The code is a little longer now, but I
158        think easier to read.
159        Note: CPP-flag MOM_VI_ORIGINAL_VISCA4 is not tested.
160    o pkg/seaice:
161      - allow to specify initial seaice velocity from files (uIceFile,vIceFile)
162    o pkg/exch2:
163      - alternative code (without tile x tile matrix) for cumulated (global) sum;
164        used as default; keep using matrix version in adjustment.cs-32x32x1.
165    o tools/build_options:
166      - after merging some MPI and/or multi-threads specific optfiles so that
167        the modified default optfile support both built (using genmake2 -mpi
168        for the MPI built, using genmake2 -omp for OpenMP built),
169        move now obsolete optfiles to tools/build_options/unsupported/
170       (add copy of email sent to support list in doc/optfiles_changes.txt)
171    
172    checkpoint63c (2011/09/28)
173    o pkg/ebm:
174      - fix ebm_zonalmean.F for several procs in Ydir (nPy > 1); update output of
175        test exp. global_ocean_ebm (affects machine truncation, 12 digits for cg2d)
176    o pkg/seaice (SItracer pickup)
177    * Simple code for pickup of SItracer fields (#define ALLOW_SITRACER)
178      To be done:
179      - thorough testing of missing fields in S/R seaice_read_pickup
180      - thorough matching between generic tracers and specific fields used
181        (e.g. volume-weighted age, area-weighted age, salinity, ...)
182    o pkg/grdchk:
183      - all procs calculate and print finite-difference gradient (for testreport)
184      - change description output used by testreport;
185      - AD testing: also compare and report Finite-difference gradient;
186        => update all output_adm*.txt
187    o test exp. global_ocean_ebm:
188      - switch back useRealFreshWaterFlux (no problem anymore with run-off);
189        and turn on exactConserve; update (fwd) output.
190    o pkg/seaice (LSR):
191      - print to STDOUT number of solver iterations at SEAICE_monFreq interval.
192      - modify solver to deal cleanly with u/v switch at face edges (CS-grid):
193        * identical results with non-CS topology (but save up to half of EXCH calls)
194        * no much changes in cs-32 verification tests since no ice at face edges
195         (differences due to convergence criteria, since nb of iterations changed)
196        * expect some differences on lat-lon-cap grid.
197        update FWD results of global_ocean.cs32x15 test exp. (icedyn & seaice)
198  o pkg/exch2:  o pkg/exch2:
199    - add new CPP option to disable Cumul-Sum matrix (to save storage when using    - add new CPP option to disable Cumul-Sum matrix (to save storage when using
200      many tiles); until alternative coding is added, just add a stop.      many tiles); until alternative coding is added, just add a stop.
