5      ==============================      ==============================
6    
7    o pkg/pp81: add diagnostics for vertical eddy viscosity and diffusivity
8      (requires new subroutines pp81_init_fixed.F/pp81_diagnostics_init.F)
9    o pkg/obcs: Stevens BCs (still only for east and west)
10      - fix Stevens BCs by using intermediate velocities of previous
11        time step as "baroclinic" contribution rather velocity of one grid cell
12        inside the boundaries; more consistent but makes the entire treatment
13        more complicated, requires new pickup files and two new S/Rs:
14        obcs_copy_uv_n and obcs_save_uv_n
15        keep old version with flag OBCS_STEVENS_USE_INTERIOR_VELOCITY
16        (undefined by default)
17      - silently move computation of some grid factors into separate loops to
18        save some recomputations
19      - add a hack for non-linear free surface
20      - add a verification experiment to exp4 that tests this code
21    o make gluemnc/xplodemnc work with (moron) non-GNU shell tools
22    
23    checkpoint63d (2011/10/25)

29      return to older implementation (same results as before); note that none of      return to older implementation (same results as before); note that none of
30      the "experimental" OBCS_SEAICE options are implemented in the new version.      the "experimental" OBCS_SEAICE options are implemented in the new version.
31      - switch test exp. seaice_obcs to use new version (update output).
32  o pkg/seaice:  o pkg/seaice:
33    - add few stop (B-grid & CS-exch, B-grid & obcs, AUTODIFF & SEAICE_maskRHS)    - add few stop (B-grid & CS-exch, B-grid & obcs, AUTODIFF & SEAICE_maskRHS)
34    - add parenthesis in Water-Ice drag calculations (evp & lsr);    - add parenthesis in Water-Ice drag calculations (evp & lsr);

44    o pkg/generic_advdiff
45      - make TAF generate code that vectorizes:
46        gad_dst3fl_adv_*.F, gad_u3c4_impl_r.F
47  o model/src:  o model/src:
48    - improve vectorization also for adjoint code of    - improve vectorization also for adjoint code of
49      solve_tridiagonal and solve_pentadiagonal. As this requires up to      solve_tridiagonal and solve_pentadiagonal. As this requires up to
50      5 new 3D-fields, this code is only turned on for the combination of      5 new 3D-fields, this code is only turned on for the combination of
51      ALLOW_AUTODIFF_TAMC and TARGET_NEC_SX.      ALLOW_AUTODIFF_TAMC and TARGET_NEC_SX. Also remove error message
52        for singular matrix check (only for TARGET_NEC_SX).
53    - remove hard-wiring of CPP-flag ALLOW_SOLVERS_KLOOPINSIDE to    - remove hard-wiring of CPP-flag ALLOW_SOLVERS_KLOOPINSIDE to
54      ALLOW_AUTODIFF. This flag now needs to be set outside of      ALLOW_AUTODIFF. This flag now needs to be set outside of
