FS (user based
fairshare factor)
The existing fairshare
feature tunes the
dynamic user priority
The fairshare factor automatically
adjusts the APS value based on
dynamic user priority.
FAIRSHARE must be defined in the
queue. The FS factor is ignored for
non-fairshare queues.
The FS factor is influenced by the
following fairshare parameters in
lsb.params:
◆ CPU_TIME_FACTOR
◆ RUN_TIME_FACTOR
◆ RUN_JOB_FACTOR
◆ HIST_HOURS
RSRC (resource
factors)
PROC Requested processors is the max of
bsub -n min, max, the min of
bsub -n min, or the value of
PROCLIMIT in lsb.queues.
MEM Total real memory requested (in MB).
Memory requests appearing to the
right of a || symbol in a usage string
are ignored in the APS calculation.
SWAP Total swap space requested (in MB).
As with MEM, swap space requests
appearing to the right of a || symbol in
a usage string are ignored.
WORK (job
attributes)
JPRIORITY The job priority specified by:
◆ Default specified by
MAX_USER_PRIORITY in
lsb.params
◆ Users with bsub -sp or
bmod -sp
◆ Automatic priority escalation
with
JOB_PRIORITY_OVER_TIME in
lsb.params
QPRIORITY The priority of the submission queue.
ADMIN Administrators use
bmod -aps to set
this subfactor value for each job. A
positive value increases the APS. A
negative value decreases the APS. The
ADMIN factor is added to the
calculated APS value to change the
factor value.
The ADMIN factor applies to the entire
job. You cannot configure separate
weight, limit, or grace period factors.
The ADMIN factor takes effect as soon
as it is set.
