Limiting the number of planned jobs

When a reservation is enabled, this has the potential to decrease cluster utilization since LSF holds resources idle in order to avoid job starvation. For this reason, some sites may wish to limit the number of jobs allowed in an allocation plan.

This can be controlled with the PLAN parameter setting at the application, queue, or cluster level::

PLAN = MAX_JOBS[<num>]

When configured at multiple levels, the strictest of these will apply.
