In the past (v 1.6.4-) we used mpirun args of --mca mpi_paffinity_alone 1 --mca btl openib,tcp,sm,self
with lsf 7.0.6, and this was enough to make cores not be oversubscribed when submitting 2 or more jobs to the same node. Now I am using 1.8.8 and thus far don't have the right combination of args to make sure cores don't oversubscribe. I am currently using: -report-bindings --map-by core --bind-to core --nooversubscribe --mca btl openib,tcp,sm,self Do I have the incorrect options or am I missing an option? Thanks for any info tom
