Automatic Job Priority Escalation
Automatic job priority escalation automatically increases job priority of jobs that have
been pending for a specified period of time. User-assigned job priority (see “User-
Assigned Job Priority” on page 382) must also be configured.
As long as a job remains pending, LSF will automatically increase the job priority beyond
the maximum priority specified by MAX_USER_PRIORITY. Job priority will not be
increased beyond the value of
max_int on your system.
Configuring job priority escalation
To configure job priority escalation edit lsb.params and define
JOB_PRIORITY_OVER_TIME. User-assigned job priority must also be configured.
Use
bparams -l to display the values of JOB_PRIORITY_OVER_TIME.
Syntax JOB_PRIORITY_OVER_TIME= increment / interval
Where:
◆ increment
Specifies the value used to increase job priority every interval minutes. Valid values
are positive integers.
◆ interval
Specifies the frequency, in minutes, to increment job priority. Valid values are
positive integers.
Example JOB_PRIORITY_OVER_TIME=3/20
Specifies that every 20 minute interval increment to job priority of pending jobs by 3.
