A job cannot hold any reserved slots after its reservation time expires.
SLOT_RESERVE=MAX_RESERVE_TIME[n].
where n is an integer by which to multiply MBD_SLEEP_TIME. MBD_SLEEP_TIME is defined in lsb.params; the default value is 60 seconds.
For example:
Begin Queue
.
PJOB_LIMIT=1
SLOT_RESERVE = MAX_RESERVE_TIME[5]
.
End Queue
In this example, if MBD_SLEEP_TIME is 60 seconds, a job can reserve job slots for 5 minutes. If MBD_SLEEP_TIME is 30 seconds, a job can reserve job slots for 5 *30= 150 seconds, or 2.5 minutes.
