LSB_SKIP_FULL_HOSTS

Description

Specifies whether LSF removes full hosts (that is, hosts with all slots occupied) from consideration at the beginning of each scheduling session.

When selecting hosts to run jobs, LSF removes unusable hosts from consideration at the beginning of each scheduling session. Hosts that are unusable by any job include hosts that are down (unavail or unreach), closed by the administrator (closed_Adm), or closed due to a load threshold (closed_Busy), and removing these hosts early in the scheduling session helps with scheduling performance.

However, LSF does not remove full hosts (closed_Full) from consideration because these hosts can still be used by jobs in preemptive queues if queue-based preemption is enabled.

If LSB_SKIP_FULL_HOSTS is enabled (set to Y), LSF removes full hosts from consideration at the beginning of each scheduling session, as long as there is no preemption relationship between the queues (for more details, refer to the PREEMPTION parameter in the lsb.queues file).
