  • Milestone changed from IPSL CM4 parallel version to IPSL CM5

First investigation is OK :

mpiexec -host 0 -n 1 oasis.ksh : -host 0 -n 1 lmdz.ksh : -host 1 -n 1 opa.ksh

avec par ex un oasis.ksh de la forme :

#!/usr/bin/ksh
./oasis > oasis_out 

Next step is to include that for IPSLCM5 configuration (with NEMO).

  • Resolution set to worksforme
  • Status changed from new to closed

This improvment is postponed since on SX8 and SX9 we still use less than 8 CPUs.
