|
o model/src: solve_*diagonal.F |
| 8 |
|
- replace division with multiplication by inverse (similar to original version) |
| 9 |
|
- fix pkg/gmredi/gmredi_calc_psi_bvp.F & pkg/ggl90/ggl90_calc.F |
| 10 |
|
to enable the use of the vectorized & differentiable solve_tridiagonal.F |
| 11 |
|
o pkg/seaice: ECCO-CLIVAR merge: |
| 12 |
|
1. seaice AREA relaxation |
| 13 |
|
* CPP option: SEAICE_ALLOW_AREA_RELAXATION |
| 14 |
|
* runtime flag: SEAICE_tauAreaObsRelax |
| 15 |
|
2. modified global mean cost imbalance code: CPP option |
| 16 |
|
ALLOW_SSH_GLOBMEAN_COST_CONTRIBUTION |
| 17 |
|
o another iteration on solve_*diagonal.F |
| 18 |
|
Make choices independent of AUTODIFF |
| 19 |
|
Default will be the adjoinable vectorized version. |
| 20 |
|
Alternative choices are: |
| 21 |
|
* non-adjoinable original version with low memory footprint: |
| 22 |
|
#define SOLVE_DIAGONAL_LOWMEMORY |
| 23 |
|
* still adjoinable but does not vectorize (k as inner-most loop): |
| 24 |
|
#define SOLVE_DIAGONAL_KINNER (keeping SOLVE_DIAGONAL_LOWMEMORY undef) |
| 25 |
|
o testreport |
| 26 |
|
- add option to use a home made wrapper around "make" |
| 27 |
|
- remove MITGCM_IEEE env. variable (no longer active) |
| 28 |
|
o pkg/shelfice |
| 29 |
|
- improve computation of friction velocity for velocity dependent |
| 30 |
|
exchange coefficients: include velocities into SHELFICEBoundaryLayer |
| 31 |
|
block to average velocities vertically |
| 32 |
|
- add TAF store directives for SHI_ALLOW_GAMMAFRICT |
| 33 |
|
o Modify diagonal solvers, now three versions (upon request): |
| 34 |
|
#ifndef SOLVE_DIAGONAL_AUTODIFF |
| 35 |
|
1. default version (dating back a while ago) |
| 36 |
|
#else /* def SOLVE_DIAGONAL_AUTODIFF */ |
| 37 |
|
# ifdef SOLVE_DIAGONAL_KINNER |
| 38 |
|
2. adjoinable version with k-innermost loop (G. Forget) |
| 39 |
|
# else |
| 40 |
|
3. adjoinable vectorized version of 2. |
| 41 |
|
# endif |
| 42 |
|
#endif /* SOLVE_DIAGONAL_AUTODIFF */ |
| 43 |
|
All flags are currently set within routines, but could/should be moved to CPP-options. |
| 44 |
|
Array bounds for 1. are as before, for 2.,3. cover the entire domain |
| 45 |
|
(could be changed for 1. too). |
| 46 |
|
o verification/lab_sea (fwd): |
| 47 |
|
- update the 4 fwd lab_sea test experiment: no longer SEAICE_GROWTH_LEGACY, |
| 48 |
|
use 7 categories (except hb87), new solve4temp params (except salt_plume), |
| 49 |
|
constant salinity (=4) or variable salinity (salt_plume) done through |
| 50 |
|
SItracer. |
| 51 |
|
o pkg/seaice: |
| 52 |
|
- rename parameters: SIsalFrac to SEAICE_saltFrac & SIsal0 to SEAICE_salt0; |
| 53 |
|
- remove old parameters ( SEAICE_freeze, SEAICEturbFluxFormula, SEAICE_gamma_t, |
| 54 |
|
SEAICE_gamma_t_frz, SEAICE_availHeatTaper & SEAICE_availHeatFracFrz) |
| 55 |
|
from SEAICE_PARMS.h ; still need to fix seaice_cost_sst.F (broken when |
| 56 |
|
SEAICE_freeze got retired) but already better than previously with |
| 57 |
|
SEAICE_freeze=123456.7 deg.C; |
| 58 |
|
- move setting of facOpenGrow/Melt from SEAICE_INIT_FIXED to SEAICE_READPARMS |
| 59 |
|
(safer multi-threaded setting); always set SEAICEuseEVP; |
| 60 |
|
- setting of ocean-ice turb. flux coeff: moved from SEAICE_CHECK to |
| 61 |
|
SEAICE_READPARMS & SEAICE_INIT_FIXED (this fixes wrong summary report); |
| 62 |
|
stop if multiple specifications for the same coeff; make sure default |
| 63 |
|
SEAICE_mcPheePiston is compatible with drF(1) & deltaT. |
| 64 |
|
o pkg/obcs: |
| 65 |
|
- allow to switch to upwind 1rst order advection scheme for the advective |
| 66 |
|
flux computation at the open-boundary; disabled for adjoint built. |
| 67 |
|
o pkg/ptracers: |
| 68 |
|
- rename PTRACERS_RESTART.h -> PTRACERS_START.h |
| 69 |
|
- rename ptracers_fields_blocking_exchanges.F -> ptracers_fields_blocking_exch.F |
| 70 |
|
- add parameter to decide when to start a tracer; use internal flag to |
| 71 |
|
know which tracer to step-forward; switch this internal flag at the top |
| 72 |
|
of forward_step.F (new S/R PTRACERS_SWITCH_ONOFF); for now, not enabled |
| 73 |
|
for adjoint built. |
| 74 |
o pkg/seaice: |
o pkg/seaice: |
| 75 |
- add SEAICE_SIZE.h anywhere in the code where SEAICE.h is included ; |
- add SEAICE_SIZE.h anywhere in the code where SEAICE.h is included ; |
| 76 |
- move MULTDIM declaration and setting from SEAICE.h to SEAICE_SIZE.h ; |
- move MULTDIM declaration and setting from SEAICE.h to SEAICE_SIZE.h ; |
