o global_ocean.cs32x15/results: three changes following from the pkg/seaice commit below. |
o model/src: |
| 8 |
- switch to variable freezing point. |
- selectAddFluid (ALLOW_ADDFLUID): add missing term in horizontal momentum |
| 9 |
|
flux-form (mom_fluxform.F) and vertical momentum (calc_gw.F) equations. |
| 10 |
|
- SOLVE_DIAGONAL: switch default to use adjoinable & vectorized version |
| 11 |
|
(#undef SOLVE_DIAGONAL_LOWMEMORY); update output of exp. front_relax.bvp. |
| 12 |
|
o model/src: solve_*diagonal.F |
| 13 |
|
- replace division with multiplication by inverse (similar to original version) |
| 14 |
|
update output of AD exp. global_ocean.90x40x15. |
| 15 |
|
- fix pkg/gmredi/gmredi_calc_psi_bvp.F & pkg/ggl90/ggl90_calc.F |
| 16 |
|
to enable the use of the vectorized & differentiable solve_tridiagonal.F |
| 17 |
|
- test exp. global_ocean.90x40x15/input_ad: switch to advection scheme 20 for |
| 18 |
|
vertical advection (to get solve_tridiagonal tested in AD mode). |
| 19 |
|
o pkg/seaice: ECCO-CLIVAR merge: |
| 20 |
|
1. seaice AREA relaxation |
| 21 |
|
* CPP option: SEAICE_ALLOW_AREA_RELAXATION |
| 22 |
|
* runtime flag: SEAICE_tauAreaObsRelax |
| 23 |
|
2. modified global mean cost imbalance code: CPP option |
| 24 |
|
ALLOW_SSH_GLOBMEAN_COST_CONTRIBUTION |
| 25 |
|
o another iteration on solve_*diagonal.F |
| 26 |
|
Make choices independent of AUTODIFF |
| 27 |
|
Default will be the adjoinable vectorized version. |
| 28 |
|
Alternative choices are: |
| 29 |
|
* non-adjoinable original version with low memory footprint: |
| 30 |
|
#define SOLVE_DIAGONAL_LOWMEMORY |
| 31 |
|
* still adjoinable but does not vectorize (k as inner-most loop): |
| 32 |
|
#define SOLVE_DIAGONAL_KINNER (keeping SOLVE_DIAGONAL_LOWMEMORY undef) |
| 33 |
|
o testreport |
| 34 |
|
- add option to use a home made wrapper around "make" |
| 35 |
|
- remove MITGCM_IEEE env. variable (no longer active) |
| 36 |
|
o pkg/shelfice |
| 37 |
|
- improve computation of friction velocity for velocity dependent |
| 38 |
|
exchange coefficients: include velocities into SHELFICEBoundaryLayer |
| 39 |
|
block to average velocities vertically |
| 40 |
|
- add TAF store directives for SHI_ALLOW_GAMMAFRICT |
| 41 |
|
o Modify diagonal solvers, now three versions (upon request): |
| 42 |
|
#ifndef SOLVE_DIAGONAL_AUTODIFF |
| 43 |
|
1. default version (dating back a while ago) |
| 44 |
|
#else /* def SOLVE_DIAGONAL_AUTODIFF */ |
| 45 |
|
# ifdef SOLVE_DIAGONAL_KINNER |
| 46 |
|
2. adjoinable version with k-innermost loop (G. Forget) |
| 47 |
|
# else |
| 48 |
|
3. adjoinable vectorized version of 2. |
| 49 |
|
# endif |
| 50 |
|
#endif /* SOLVE_DIAGONAL_AUTODIFF */ |
| 51 |
|
All flags are currently set within routines, but could/should be moved to CPP-options. |
| 52 |
|
Array bounds for 1. are as before, for 2.,3. cover the entire domain |
| 53 |
|
(could be changed for 1. too). |
| 54 |
|
o verification/lab_sea (fwd): |
| 55 |
|
- update the 4 fwd lab_sea test experiment: no longer SEAICE_GROWTH_LEGACY, |
| 56 |
|
use 7 categories (except hb87), new solve4temp params (except salt_plume), |
| 57 |
|
constant salinity (=4) or variable salinity (salt_plume) done through |
| 58 |
|
SItracer. |
| 59 |
|
o pkg/seaice: |
| 60 |
|
- rename parameters: SIsalFrac to SEAICE_saltFrac & SIsal0 to SEAICE_salt0; |
| 61 |
|
- remove old parameters ( SEAICE_freeze, SEAICEturbFluxFormula, SEAICE_gamma_t, |
| 62 |
|
SEAICE_gamma_t_frz, SEAICE_availHeatTaper & SEAICE_availHeatFracFrz) |
| 63 |
|
from SEAICE_PARMS.h ; still need to fix seaice_cost_sst.F (broken when |
| 64 |
|
SEAICE_freeze got retired) but already better than previously with |
| 65 |
|
SEAICE_freeze=123456.7 deg.C; |
| 66 |
|
- move setting of facOpenGrow/Melt from SEAICE_INIT_FIXED to SEAICE_READPARMS |
| 67 |
|
(safer multi-threaded setting); always set SEAICEuseEVP; |
| 68 |
|
- setting of ocean-ice turb. flux coeff: moved from SEAICE_CHECK to |
| 69 |
|
SEAICE_READPARMS & SEAICE_INIT_FIXED (this fixes wrong summary report); |
| 70 |
|
stop if multiple specifications for the same coeff; make sure default |
| 71 |
|
SEAICE_mcPheePiston is compatible with drF(1) & deltaT. |
| 72 |
|
o pkg/obcs: |
| 73 |
|
- allow to switch to upwind 1rst order advection scheme for the advective |
| 74 |
|
flux computation at the open-boundary; disabled for adjoint built. |
| 75 |
|
o pkg/ptracers: |
| 76 |
|
- rename PTRACERS_RESTART.h -> PTRACERS_START.h |
| 77 |
|
- rename ptracers_fields_blocking_exchanges.F -> ptracers_fields_blocking_exch.F |
| 78 |
|
- add parameter to decide when to start a tracer; use internal flag to |
| 79 |
|
know which tracer to step-forward; switch this internal flag at the top |
| 80 |
|
of forward_step.F (new S/R PTRACERS_SWITCH_ONOFF); for now, not enabled |
| 81 |
|
for adjoint built. |
| 82 |
|
o pkg/seaice: |
| 83 |
|
- add SEAICE_SIZE.h anywhere in the code where SEAICE.h is included ; |
| 84 |
|
- move MULTDIM declaration and setting from SEAICE.h to SEAICE_SIZE.h ; |
| 85 |
|
- keep experiment offline_exf_seaice truly single category (set MULTDIM=1). |
| 86 |
|
o pkg/ecco: |
| 87 |
|
- fix writing of output file DiagnosCost_ClimSalt/Theta |
| 88 |
|
and DiagnosCost_DriftSalt/Theta (if multi-tiles per proc). |
| 89 |
|
o pkg/seaice: |
| 90 |
|
- add missing initialisation of COR_ICE array in dynsolver.F |
| 91 |
|
- merging SEAICE_MULTICATEGORY define and undef cases. Now the same code is |
| 92 |
|
compiled either way, and is tested in all exps (multidim was only tested |
| 93 |
|
in lab_sea ad before). |
| 94 |
|
- cosmetic change to prepare for future addition of ITD. no change to results. |
| 95 |
|
no defaults change. |
| 96 |
|
- added run time param SEAICE_multDim (7 for SEAICE_MULTICATEGORY, 1 otherwise). |
| 97 |
|
- by lack of adequate verification experiments, I further used custom versions |
| 98 |
|
of global_ocean.cs32x15 to test multicat or not, with pickup or not. All |
| 99 |
|
should be correct. |
| 100 |
|
- avoid recomputations in ad. |
| 101 |
|
o array initialisation in adjoint mode: |
| 102 |
|
1) pkg/mom_common/mom_calc_ke.F: |
| 103 |
|
add full array initialisation of KE inside mom_calc_ke.F (ALLOW_AUTODIFF_TAMC): |
| 104 |
|
The S/R which calls MOM_CALC_KE initialises KE but in some recomputation |
| 105 |
|
part this initialisation is gone, resulting in Floating Point Exception |
| 106 |
|
(caught by open64 compiler with debug option). |
| 107 |
|
2) model/src/convective_weights.F |
| 108 |
|
set output convectCount over the full array range (instead of doing |
| 109 |
|
an update): this fix a similar issue when called within recomputation (adjoint) |
| 110 |
|
which could by-pass the initialisation (normally done in the caller S/R). |
| 111 |
|
o pkg/seaice: |
| 112 |
|
- final version of turbulent flux params, as agreed at MIT ice meet: |
| 113 |
|
SEAICE_mcPheePiston (default is ~ 0.000875) |
| 114 |
|
SEAICE_mcPheeTaper (default is 0.) |
| 115 |
|
SEAICE_frazilFrac (defualt is 1.) |
| 116 |
|
SEAICE_mcPheeStepFunc (default is false) |
| 117 |
|
- changes results at trunction error level |
| 118 |
|
- ifdef SEAICE_EXTERNAL_FLUXES, disallow SEAICE_waterAlbedo |
| 119 |
|
o added pkg/frazil: |
| 120 |
|
- see frazil_description.tex for details |
| 121 |
|
- verification experiment is global_with_exf/input.yearly; changes output.yearly.txt |
| 122 |
|
o pkg/shelfice/shelfice_thermodynamics.F |
| 123 |
|
- fix exponents for velocity dependent exchange coefficients: change |
| 124 |
|
from 2/3(=0) to 0.66666666666666667 |
| 125 |
|
- move computation of velocity dependent exchange coefficients into |
| 126 |
|
separate loop, so that it applies to both thermodynamics |
| 127 |
|
- move some divisions by constants out of loops |
| 128 |
|
|
| 129 |
|
checkpoint63j (2012/02/16) |
| 130 |
|
o pkg/seaice: |
| 131 |
|
- overhaul of seaice_summary.F after feb 2012 clean-up of seaice_growth.F etc. |
| 132 |
|
- SItracer: added run time params, and allow coupling to ocn salinity. |
| 133 |
|
o pkg/seaice: remove (almost) all divisions by constants within loops |
| 134 |
|
in seaice_growth.F and seaice_solve4temp.F, this changes (only) the cg2d |
| 135 |
|
results of global_ocean.cs32x15.seaice from 16 to 11 digits (but only |
| 136 |
|
those, caused by 1/QI -> recip_QI) -> update output.seaice.txt, |
| 137 |
|
output_adm.seaice_dynmix.txt and also lab_sea: output_adm.evp.txt |
| 138 |
|
o pkg/seaice : |
| 139 |
|
- simplify McPhee tapering, and allow to use it with SEAICEturbFluxFormula |
| 140 |
|
= 1 or 2, using newly added run time parameter SEAICE_availHeatTaper. |
| 141 |
|
- fix d_AREAbyATM, d_AREAbyOCN, d_AREAbyICE diags I broke in r1.148. |
| 142 |
|
- add permanent SItflux diag that corresponds to TFLUX but includes |
| 143 |
|
ice+snow. Hence SItflux-TFLUX should match the ice+snow heat budget. |
| 144 |
|
- allow activation/testing of a fix for suspected missing term in |
| 145 |
|
ocn-ice heat budget (to be confirmed). To test this, you want to |
| 146 |
|
undef SEAICE_DISABLE_HEATCONSFIX, and then set the run time param |
| 147 |
|
SEAICEheatConsFix to .TRUE. that also allows the 'SIaaflux' diagnostic. |
| 148 |
|
- no change in results, fwd or ad. |
| 149 |
|
o global_ocean.cs32x15/results: 3 changes following from the pkg/seaice commit below: |
