4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o exch2:
8      change index bounds in rx2_cube exchanges (new S/R: EXCH2_GET_UV_BOUNDS)
9      - no longer depend on the order sequence (N,S,E,W).
10      - 3rd exchange no longer needed (tested with 24 tiles).
11      - same modif to hand-written adjoint S/R (global_ocean.cs32x15: zero diff)
12      - exch_UV_A-grid readily available (but not yet tested).
13      comment out 3rd exch call and remove copy of V to U at SE & NE face-corners
14      (both are no longer needed) in exch_uv: no effect in forward run; but
15       get truncation error differences with adjoint exch.
16    o exch2:
17     - change index-bounds storage (moved from target to local tile,
18       more intuitive this way) ; rename/remove some variables.
19     - change utils/exch2/matlab-topology-generator & code_mods accordingly.
20    
21    checkpoint61a
22    o exch2/matlab-topology-generator:
23      fix bug in index bounds for N-S internal exchange (hard to tell if this
24      had any effect on the solution).
25    o pkg/mnc: small fix in mnc_handle_err: make sure that length of msgbuf
26      is exceeded
27    o testreport: modify syntax of awk, so that it works also with
28      awk, and not only with nawk and gawk
29    
30    checkpoint61
31    o autodiff
32      Change default for TAF usage by removing argument '-nonew_arg'
33      This changes TAF subroutine argument list (ordering of active var.)
34      Omission of this flag leads to incompatibility w.r.t. TAMC
35      To restore TAMC-compatibility, need following modifs:
36      * use adoptfile tools/adjoint_options/adjoint_tamc_compatibility
37      * use CPP option #define AUTODIFF_TAMC_COMPATIBILITY
38      Tested TAF version is 1.9.22
39      N.B.: exch2 hand-written adjoint code currently not TAMC compatible
40    
41    checkpoint60
42    --->>> This is the last checkpoint for which generating the adjoint
43    --->>> is done via the TAMC-compatibility TAF-flag "-nonewarg"
44    --->>> by default.
45    --->>> Future checkpoints will ommit this flag by default.
46    o pkg/generic_advdiff, os7mp: simplify and avoid division by zero.
47    o pkg/grdchk: Add gradient check to etan0 perturbations.
48    o pkg/exf: read ice area from file (#ifdef ALLOW_ICE_AREAMASK).
49    o pkg/autodiff: more flexibility in zeroadj.
50      model/src: modifying do_oceanic_phys.F accordingly.
51    o pkg/ctrl: Bounds for (kapgm,kapredi,eddypsi) parameter estimation.
52    o model/src and pkg/gmredi: GMREDI_WITH_STABLE_ADJOINT CPP option
53      special setup of gmredi for which the adjoint is stable
54      enough for parameter optimization.
55  o bridging the gap between eddy stress and GM.  o bridging the gap between eddy stress and GM.
56    -> eddyTau is replaced with eddyPsi (eddyTau = f x rho0 x eddyPsi)    -> eddyTau is replaced with eddyPsi (eddyTau = f x rho0 x eddyPsi)

68    from per-face file (take S/R READSYMTILE_RS out of ini_curvilinear_grid.F);    from per-face file (take S/R READSYMTILE_RS out of ini_curvilinear_grid.F);
