Subject: Re: [OMPI users] torque integration when tm ras/plm isn't compiled in.

OMPI_MCA_orte_leave_session_attached=1

Note: this does set limits on scale, though, if the system uses an ssh
launcher. There are system limits on the number of open ssh sessions
you can have at any one time.

For all other launchers, no limit issues exist that I know about.
