|
o pkg/ctrl: require a specific set of control variables and exf-flags for |
| 8 |
|
adjoint of seaice (stop in ctrl_check.F if conditions are not satisfied) |
| 9 |
|
o model/src: |
| 10 |
|
a) 1rst version of a new driver S/R to turn-off output freq and flags after the |
| 11 |
|
1rst forward sweep, to avoid over-writing output files during recomputations |
| 12 |
|
recomputations (& grdchk); called from cost_final.F (& ctrl_init_ctrlvar.F ?) |
| 13 |
|
b) 2nd version: |
| 14 |
|
- add specific pkg S/R for seaice & ptracers (called from S/R TURNOFF_MODEL_IO); |
| 15 |
|
- switch-off more output flags (exf_monFreq, chkPtFreq, dumpInitAndLast, |
| 16 |
|
writePickupAtEnd) + seaice & ptracers output; |
| 17 |
|
- do not switch off MNC flags (otherwise, won't get admonitor netcdf file) |
| 18 |
|
o model/src: |
| 19 |
|
- new S/R rotate_uv2en_rl (..._rs) that rotates vector fields. |
| 20 |
|
o pkg/exch2: |
| 21 |
|
- remove "simulationMode" from arg. list of S/R EXCH2_RX1,2_CUBE ; |
| 22 |
|
- add argument "signOption" to EXCH2_RX1_CUBE (will be needed for SM exch). |
| 23 |
|
o pkg/autodiff & exch2: |
| 24 |
|
process exch_uv_agrid_3d_rx.f & exch2_uv_agrid_3d_rx.f through TAF |
| 25 |
|
(for now, only if ALLOW_EXCH2 is defined). |
| 26 |
|
o pkg/autodiff: |
| 27 |
|
- include PACKAGES_CONFIG.h in exch*ad.flow & exch*ad.F |
| 28 |
|
(not supposed to be in CPP_OPTIONS.h) to get ALLOW_EXCH2 defined correctly. |
| 29 |
|
+ clean-up comments (_RS is not always real*4) |
| 30 |
|
- fix bug in ADEXCH_UV_3D_RX (without EXCH2, was calling the forward exch S/R) |
| 31 |
|
- add a stop in ADEXCH_UV_AGRID_3D_RX if trying to use it with EXCH2: |
| 32 |
|
was calling a forward exch2, which is wrong ; used in SEAICE & EXF pkgs. |
| 33 |
|
o testreport (AD-tests): |
| 34 |
|
no longer link files from dir "../input" (1rst link files from |
| 35 |
|
"../input_ad.[xx]" if secondary test "xx" and then from "../input_ad") |
| 36 |
|
|
| 37 |
|
checkpoint62f (2010/04/29) |
| 38 |
|
o model/src/the_main_loop.F: |
| 39 |
|
adjust store directives for seaice evp and multicategory according to |
| 40 |
|
pkg/ecco/the_main_loop.F |
| 41 |
