LSF Version 7.3 - Platform LSF Configuration Reference

applications are running provided those applications are running on the same host under the
same user.
Assumptions and limitations
•
Per-resource configuration defines resource usage for individual resources, but it does not
change any existing resource limit behavior (PER_JOB, PER_SLOT).
•
In a MultiCluster environment, you should configure resource usage in the scheduling
cluster (submission cluster in lease model or receiving cluster in job forward model).
Automatic time-based configuration
Variable configuration is used to automatically change LSF configuration based on time
windows. You define automatic configuration changes in lsb.resources by using if-else
constructs and time expressions. After you change the files, reconfigure the cluster with the
badmin reconfig command.
The expressions are evaluated by LSF every 10 minutes based on mbatchd start time. When
an expression evaluates true, LSF dynamically changes the configuration based on the
associated configuration statements. Reconfiguration is done in real time without restarting
mbatchd, providing continuous system availability.
Example
# limit usage of hosts in 'license1' group and time
# based configuration
# - 10 jobs can run from normal queue
# - any number can run from short queue between 18:30
# and 19:30
# all other hours you are limited to 100 slots in the
# short queue
# - each other queue can run 30 jobs
Begin Limit
PER_QUEUE HOSTS SLOTS # Example
normal license1 10
# if time(18:30-19:30)
short license1 -
#else
short license1 100
#endif
(all ~normal ~short) license1 30
