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
