Automatic Job Priority Escalation
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 296) 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.
