LSB_DISABLE_LIMLOCK_EXCL

Syntax

LSB_DISABLE_LIMLOCK_EXCL=y | n

Description

If preemptive scheduling is enabled, this parameter enables preemption of and preemption by exclusive jobs when PREEMPT_JOBTYPE=EXCLUSIVE in lsb.params. Changing this parameter requires a restart of all sbatchds in the cluster (badmin hrestart). Do not change this parameter while exclusive jobs are running.

When LSB_DISABLE_LIMLOCK_EXCL=y, for a host running an exclusive job:

LIM is not locked on a host running an exclusive job
lsload displays the host status ok.
bhosts displays the host status closed.
Users can run tasks on the host using lsrun or lsgrun. To prevent users from running tasks during execution of an exclusive job, the parameter LSF_DISABLE_LSRUN=y must be defined in lsf.conf.

Default

Set to y at time of installation. If otherwise undefined, then n (LSF locks the LIM on a host running an exclusive job and unlocks the LIM when the exclusive job finishes).
