Re: [OMPI users] using OpenMPI + SGE in a heterogeneous network

Hi John I associate a PE with each of the two hostgroups, say orte_mx and orte_ib. The user can then submit with -pe orte\* thus leaving the selection of the hostgroup to SGE. The PE startup script would be the same and by passing it SGE variables like $host etc the script can figure out what
