|
o pkg/seaice |
| 8 |
|
- change (once again) the discretization for the evp solver: rather than |
| 9 |
|
squaring the averages of strain rates, average the squares to give |
| 10 |
|
a better approximation to VP behavior (in simple test); this breaks |
| 11 |
|
verification experiments that use EVP (lab_sea and lab_sea.hb87) |
| 12 |
|
--> update outputs |
| 13 |
|
o add CPP-flag (in mom_calc_visc.F) and TAF directive (in gmredi_slope_limit) |
| 14 |
|
to improve vectorization of adjoint code on TARGET_NEC_SX |
| 15 |
|
o verification/vermix: |
| 16 |
|
- change vermix to a more "classical" 1d column with high vertical |
| 17 |
|
resolution, seasonal heat flux forcing and constant wind forcing |
| 18 |
|
--> update outputs |
| 19 |
|
o pkg/seaice |
| 20 |
|
- fix diagnostics of principal stress components for EVP |
| 21 |
|
- add optional diagnostics of non-linear convergence for LSOR solver |
| 22 |
|
- make maximum zeta a runtime parameter |
| 23 |
|
o model/src (3-d solver): |
| 24 |
|
Undo modif from Dec 12, 2005 (solve_for_pressure.F cvs version v.49), |
| 25 |
|
which consisted in removing the Surf. Non-Hydrostatic pressure from the |
| 26 |
|
whole column and adding it to Eta (inspired from Casualli, 1999): |
| 27 |
|
Only affects 3-D solver initial guess and only if using ExactConserv, |
| 28 |
|
but tests did show a degradation of solver convergence. For this reason, |
| 29 |
|
decide to disable this piece of code. |
| 30 |
|
to recover previous version, just set zeroPsNH = exactConserv (line 78). |
| 31 |
|
Update output of exp. global_ocean.cs32x15.viscA4 & hs94.cs-32x32x5.impIGW |
| 32 |
|
o pkg/ggl90: |
| 33 |
|
- fix previous modif (unfortunatly has not been documented here). |
| 34 |
|
o pkg/seaice/autodiff: |
| 35 |
|
- add CPP flag to include clipping of zeta in EVP code; |
| 36 |
|
although clipping of zeta is not necessary for EVP and not recommended |
| 37 |
|
it was done by default, now clipping is disabled by default |
| 38 |
|
- modify computation and store zetaC/Z in seaice_evp for TAF |
| 39 |
|
- add CPP-flag SEAICE_ALLOW_CLIPVELS (undefined by default) |
| 40 |
|
- change seaice_calc_viscosities/strainrates for better |
| 41 |
|
vectorization after AD by TAF |
| 42 |
|
- rearrange common blocks in SEAICE.h once again for easier dumps of |
| 43 |
|
adjoint output, adjust adcommon.h and g_common.h |
| 44 |
|
- change flux form of default advection scheme for better vectorization |
| 45 |
|
of adjoint code |
| 46 |
|
- modify lab_sea/input.lsr to test the flux form of default advection |
| 47 |
|
scheme |
| 48 |
|
o autodiff: fix seaice fields in g_common.h (left over from 3 to 1 level |
| 49 |
|
transition in checkpoint61r) |
| 50 |
|
|
| 51 |
|
checkpoint61x |
| 52 |
|
o adjoint: adding two new verification experiments |
| 53 |
|
* tutorial_global_biogeo: an online dic sensitivity experiment |
| 54 |
|
(work with G. Forget) |
| 55 |
|
* tutorial_dic_adjoffline: an offline dic sensitivity experiment |
| 56 |
|
(an update of the Dutkiewicz et al., 2006 paper) |
| 57 |
|
Both use the same CO2FLUX cost function, but different controls |
| 58 |
|
Gradient checks look good, but some recomp. could still be traightened out |
| 59 |
|
Should add xx_dic control variable to test at some point |
| 60 |
|
o model/src: |
| 61 |
|
add run-time parameters to check and/or mask initial Temp & Salt |
| 62 |
|
o pkg/ptracers: |
| 63 |
|
apply zonal filter (if used) to all passive tracers |
| 64 |
|
|
| 65 |
|
checkpoint61w |
| 66 |
|
o adjoint: |
| 67 |
|
* update and finish work on adjoint of dic package (G. Forget) |
| 68 |
|
* start adjoint of offline package |
| 69 |
|
* bug fix for cube-sphere TLM code (active_file_g.F) |
| 70 |
o tutorial_global_oce_optim: |
o tutorial_global_oce_optim: |
| 71 |
now tested with 4 tiles (change data.grdchk and update output_adm.txt) |
now tested with 4 tiles (change data.grdchk and update output_adm.txt) |
| 72 |
and add SIZE.h_mpi for MPI testing |
