TASK_SWAPLIMIT: Enables enforcement of a virtual memory (swap) limit (bsub -v, bmod

-v, or SWAPLIMIT in lsb.queues) for individual tasks in a parallel job. If any parallel task

exceeds the swap limit, LSF terminates the entire job.

Example JOB_START events in lsb.events:

For a job submitted with

bsub -n 64 -R "span[ptile=32]" sleep 100

Without SHORT_EVENTFILE, a JOB_START event like the following would be logged in

lsb.events:

"JOB_START" "7.0" 1058989891 710 4 0 0 10.3 64 "hostA" "hostA" "hostA" "hostA" "hostA" "hostA"

"hostB" "hostB" "hostB" "hostB" "hostB" "hostB" "hostB" "hostB" "hostB" "hostB" "" "" 0 "" 0

With SHORT_EVENTFILE, a JOB_START event would be logged in lsb.events with the

number of execution hosts (numExHosts field) changed from 64 to 2 and the execution host

list (execHosts field) shortened to "32*hostA" and "32*hostB":

"JOB_START" "7.0" 1058998174 812 4 0 0 10.3 2 "32*hostA" "32*hostB" "" "" 0 "" 0 ""

Example JOB_FINISH records in lsb.acct:

For a job submitted with

bsub -n 64 -R "span[ptile=32]" sleep 100

Without SHORT_EVENTFILE, a JOB_FINISH event like the following would be logged in

lsb.acct:

"JOB_FINISH" "7.0" 1058990001 710 33054 33816578 64 1058989880 0 0 1058989891 "user1" "normal"

Example bjobs -l ouput without SHORT_PIDLIST:

bjobs -l displays all the PGIDs and PIDs for the job:
