LSF Version 7.3 - Platform LSF Configuration Reference

Counts only running jobs when evaluating if a user group is approaching its total job
slot limit (SLOTS, PER_USER=all, and HOSTS in the lsb.resources file).
Suspended jobs are ignored when this keyword is used. When preemptive scheduling
is enabled, suspended jobs never count against the total job slot limit for individual
users.
HOST_JLU
Counts only running jobs when evaluating if a user or user group is approaching its
per-host job slot limit (SLOTS and USERS in the lsb.resources file). Suspended
jobs are ignored when this keyword is used.
LEAST_RUN_TIME
Preempts the job that has been running for the shortest time. Run time is wall-clock
time, not normalized run time.
MINI_JOB
Optimizes the preemption of parallel jobs by preempting only enough parallel jobs to
start the high-priority parallel job.
USER_JLP
Counts only running jobs when evaluating if a user is approaching their per-processor
job slot limit (SLOTS_PER_PROCESSOR, USERS, and PER_HOST=all in the
lsb.resources file). Suspended jobs are ignored when this keyword is used. Ignores
suspended jobs when calculating the user-processor job slot limit for individual users.
When preemptive scheduling is enabled, suspended jobs never count against the total
job slot limit for individual users.
Default
The parameter is not defined.
If preemptive scheduling is enabled, more lower-priority parallel jobs may be preempted than
necessary to start a high-priority parallel job. Both running and suspended jobs are counted
when calculating the number of job slots in use, except for the following limits:
•
The total job slot limit for hosts, specified at the host level
•
Total job slot limit for individual users, specified at the user level—by default, suspended
jobs still count against the limit for user groups
PREEMPT_JOBTYPE
Syntax
PREEMPT_JOBTYPE=[EXCLUSIVE] [BACKFILL]
Description
If preemptive scheduling is enabled, this parameter enables preemption of exclusive and
backfill jobs.
Specify one or both of the following keywords. Separate keywords with a space.
