wake.F @ 1784

Last change on this file since 1784 was 1403, checked in by Laurent Fairhead, 14 years ago

Merged LMDZ4V5.0-dev branch changes r1292:r1399 to trunk.

Validation:
Validation consisted in compiling the HEAD revision of the trunk,
LMDZ4V5.0-dev branch and the merged sources and running different
configurations on local and SX8 machines comparing results.

Local machine: bench configuration, 32x24x11, gfortran

IPSLCM5A configuration (comparison between trunk and merged sources):
- numerical convergence on dynamical fields over 3 days
- start files are equivalent (except for RN and PB fields)
- daily history files equivalent

MH07 configuration, new physics package (comparison between LMDZ4V5.0-dev branch and merged sources):
- numerical convergence on dynamical fields over 3 days
- start files are equivalent (except for RN and PB fields)
- daily history files equivalent

SX8 machine (brodie), 96x95x39 on 4 processors:

IPSLCM5A configuration:
- start files are equivalent (except for RN and PB fields)
- monthly history files equivalent

MH07 configuration:
- start files are equivalent (except for RN and PB fields)
- monthly history files equivalent

Changes to the makegcm and create_make_gcm scripts to take into account
main programs in F90 files

Fusion de la branche LMDZ4V5.0-dev (r1292:r1399) au tronc principal

Validation:
La validation a consisté à compiler la HEAD de le trunk et de la banche
LMDZ4V5.0-dev et les sources fusionnées et de faire tourner le modéle selon
différentes configurations en local et sur SX8 et de comparer les résultats

En local: 32x24x11, config bench/gfortran

pour une config IPSLCM5A (comparaison tronc/fusion):
- convergence numérique sur les champs dynamiques après 3 jours
- restart et restartphy égaux (à part sur RN et Pb)
- fichiers histoire égaux

pour une config nlle physique (MH07) (comparaison LMDZ4v5.0-dev/fusion):
- convergence numérique sur les champs dynamiques après 3 jours
- restart et restartphy égaux
- fichiers histoire équivalents

Sur brodie, 96x95x39 sur 4 proc:

pour une config IPSLCM5A:
- restart et restartphy égaux (à part sur RN et PB)
- pas de différence dans les fichiers histmth.nc

pour une config MH07
- restart et restartphy égaux (à part sur RN et PB)
- pas de différence dans les fichiers histmth.nc

Changement sur makegcm et create_make-gcm pour pouvoir prendre en compte des
programmes principaux en *F90
