Changeset 1528 for trunk/libIGCM/libIGCM_config/libIGCM_config.ksh

Timestamp:

Message:

Irene-amd : added 2 functionalities to increase computing performances :

• increase this number of cores per MPI process (OpenMP thread) by using DEP keyword in config.card
• use of dedicated nodes for XIOS servers by using DEDICATED keyword in config.card

Example of config.card :
ATM= (gcm.e, lmdz.x, 71MPI, 8OMP, 2DEP)
SRF= ("" ,"" )
SBG= ("" ,"" )
OCE= (opa, opa.xx, 360MPI, 2DEP)
ICE= ("" ,"" )
MBG= ("" ,"" )
CPL= ("", "" )
IOS= (xios_server.exe, xios.x, 12MPI,2DEP, DEDICATED)
