checkpoint61b |
| 8 |
|
o exch2: |
| 9 |
|
change index bounds in rx2_cube exchanges (new S/R: EXCH2_GET_UV_BOUNDS) |
| 10 |
|
- no longer depend on the order sequence (N,S,E,W). |
| 11 |
|
- 3rd exchange no longer needed (tested with 24 tiles). |
| 12 |
|
- same modif to hand-written adjoint S/R (global_ocean.cs32x15: zero diff) |
| 13 |
|
- exch_UV_A-grid readily available (but not yet tested). |
| 14 |
|
comment out 3rd exch call and remove copy of V to U at SE & NE face-corners |
| 15 |
|
(both are no longer needed) in exch_uv: no effect in forward run; but |
| 16 |
|
get truncation error differences with adjoint exch. |
| 17 |
|
o exch2: |
| 18 |
|
- change index-bounds storage (moved from target to local tile, |
| 19 |
|
more intuitive this way) ; rename/remove some variables. |
| 20 |
|
- change utils/exch2/matlab-topology-generator & code_mods accordingly. |
| 21 |
|
|
| 22 |
|
checkpoint61a |
| 23 |
|
o exch2/matlab-topology-generator: |
| 24 |
|
fix bug in index bounds for N-S internal exchange (hard to tell if this |
| 25 |
|
had any effect on the solution). |
| 26 |
|
o pkg/mnc: small fix in mnc_handle_err: make sure that length of msgbuf |
| 27 |
|
is exceeded |
| 28 |
|
o testreport: modify syntax of awk, so that it works also with |
| 29 |
|
awk, and not only with nawk and gawk |
| 30 |
|
|
| 31 |
|
checkpoint61 |
| 32 |
|
o autodiff |
| 33 |
|
Change default for TAF usage by removing argument '-nonew_arg' |
| 34 |
|
This changes TAF subroutine argument list (ordering of active var.) |
| 35 |
|
Omission of this flag leads to incompatibility w.r.t. TAMC |
| 36 |
|
To restore TAMC-compatibility, need following modifs: |
| 37 |
|
* use adoptfile tools/adjoint_options/adjoint_tamc_compatibility |
| 38 |
|
* use CPP option #define AUTODIFF_TAMC_COMPATIBILITY |
| 39 |
|
Tested TAF version is 1.9.22 |
| 40 |
|
N.B.: exch2 hand-written adjoint code currently not TAMC compatible |
| 41 |
