5      ==============================      ==============================
6    
7    o vermix test experiment: switch from LINEAR EOS to MDJWF (not tested before)
8    o new pkg: down_slope
9      density-driven downsloping flow parameterisation (Tellus, 1999, 412-430).
10      - presently, modify T & S inland (dwnslp_calc_rho.F).
11        can be avoided if rho was stored in common bloc and used in calc_phi_hyd.
12      - implementation for ocean in P-coords not tested.
13      - add secondary test to global_ocean.90x40x15 (input.dwnslp) to check this pkg.
14    o move kSurfC,kSurfW & kSurfS from SURFACE.h to GRID.h (next to kLowC)
15      (to facilitate conversion of oceanic pkg to p-coordinate).
16    o change FIND_RHO to FIND_RHO_2D :
17      pass arguments tFld & sFld as local (tile) 2D-arrays ; +fix EOS_CHECK.
18    o new pkg: cheapaml
19    
20    checkpoint61b
21    o exch2:
22      change index bounds in rx2_cube exchanges (new S/R: EXCH2_GET_UV_BOUNDS)
23      - no longer depend on the order sequence (N,S,E,W).
24      - 3rd exchange no longer needed (tested with 24 tiles).
25      - same modif to hand-written adjoint S/R (global_ocean.cs32x15: zero diff)
26      - exch_UV_A-grid readily available (but not yet tested).
27      comment out 3rd exch call and remove copy of V to U at SE & NE face-corners
28      (both are no longer needed) in exch_uv: no effect in forward run; but
29       get truncation error differences with adjoint exch.
30    o exch2:
31     - change index-bounds storage (moved from target to local tile,
32       more intuitive this way) ; rename/remove some variables.
33     - change utils/exch2/matlab-topology-generator & code_mods accordingly.
34    
35    checkpoint61a
36    o exch2/matlab-topology-generator:
37      fix bug in index bounds for N-S internal exchange (hard to tell if this
38      had any effect on the solution).
39    o pkg/mnc: small fix in mnc_handle_err: make sure that length of msgbuf
40      is exceeded
41    o testreport: modify syntax of awk, so that it works also with
42      awk, and not only with nawk and gawk
43    
44    checkpoint61
45    o autodiff
46      Change default for TAF usage by removing argument '-nonew_arg'
47      This changes TAF subroutine argument list (ordering of active var.)
48      Omission of this flag leads to incompatibility w.r.t. TAMC
49      To restore TAMC-compatibility, need following modifs:
50      * use adoptfile tools/adjoint_options/adjoint_tamc_compatibility
51      * use CPP option #define AUTODIFF_TAMC_COMPATIBILITY
52      Tested TAF version is 1.9.22
53      N.B.: exch2 hand-written adjoint code currently not TAMC compatible
54    
55    checkpoint60
56    --->>> This is the last checkpoint for which generating the adjoint
57    --->>> is done via the TAMC-compatibility TAF-flag "-nonewarg"
58    --->>> by default.
59    --->>> Future checkpoints will ommit this flag by default.
60    o pkg/generic_advdiff, os7mp: simplify and avoid division by zero.
61    o pkg/grdchk: Add gradient check to etan0 perturbations.
62  o pkg/exf: read ice area from file (#ifdef ALLOW_ICE_AREAMASK).  o pkg/exf: read ice area from file (#ifdef ALLOW_ICE_AREAMASK).
63  o pkg/autodiff: more flexibility in zeroadj.  o pkg/autodiff: more flexibility in zeroadj.
64    model/src: modifying do_oceanic_phys.F accordingly.    model/src: modifying do_oceanic_phys.F accordingly.
