When you want to launch a parallel job with SSGE, you have to do something like that : “qsub -N MYJOB -pe mpi 12 myjob”. the parallel environment “mpi” alllows to book slots and to create a PE_HOSTFILE filled with the list of the allocated nodes, as you know. You can use this PE_HOSTFILE to create a machinefile to use with mpiexec.
for the moment, i have tried the field native: “-pe mpi <%= num_cores %>” inside the submit file without success and i get this error message : "qsub: invalid option argument “-pe mpi 12"”
some ideas, please ?
