LSF Version 7.3 - Platform LSF Configuration Reference

The status of the closed host is closed_Adm. No new jobs are dispatched to this host, but
currently running jobs are not suspended.
RESERVE_BY_STARTTIME : LSF selects the reservation that gives the job the earliest
predicted start time.
By default, if multiple host groups are available for reservation, LSF chooses the largest possible
reservation based on number of slots.
SHORT_EVENTFILE : Compresses long host name lists when event records are written to
lsb.events and lsb.acct for large parallel jobs. The short host string has the format:
number_of_hosts*real_host_name
Tip:
When SHORT_EVENTFILE is enabled, older daemons and
commands (pre-LSF Version 7) cannot recognize the lsb.acct and
lsb.events file format.
For example, if the original host list record is
6 "hostA" "hostA" "hostA" "hostA" "hostB" "hostC"
redundant host names are removed and the short host list record becomes
3 "4*hostA" "hostB" "hostC"
When LSF_HPC_EXTENSIONS="SHORT_EVENTFILE" is set, and LSF reads the host list
from lsb.events or lsb.acct, the compressed host list is expanded into a normal host list.
SHORT_EVENTFILE affects the following events and fields:
•
JOB_START in lsb.events when a normal job is dispatched
•
numExHosts (%d)
•
execHosts (%s)
•
JOB_CHUNK in lsb.events when a job is inserted into a job chunk
•
numExHosts (%d)
•
execHosts (%s)
•
JOB_FORWARD in lsb.events when a job is forwarded to a MultiCluster leased host
•
numReserHosts (%d)
•
reserHosts (%s)
•
JOB_FINISH record in lsb.acct
•
numExHosts (%d)
•
execHosts (%s)
SHORT_PIDLIST : Shortens the output from bjobs to omit all but the first process ID (PID)
for a job. bjobs displays only the first ID and a count of the process group IDs (PGIDs) and
process IDs for the job.
Without SHORT_PIDLIST, bjobs -l displays all the PGIDs and PIDs for the job. With
SHORT_PIDLIST set, bjobs -l displays a count of the PGIDS and PIDs.
TASK_MEMLIMIT : Enables enforcement of a memory limit (bsub -M, bmod -M, or
MEMLIMIT in lsb.queues) for individual tasks in a parallel job. If any parallel task exceeds
the memory limit, LSF terminates the entire job.
