SBD_SLEEP_TIME

Syntax

SBD_SLEEP_TIME=seconds

Description

The interval at which LSF checks the load conditions of each host, to decide whether jobs on the host must be suspended or resumed.

The job-level resource usage information is updated at a maximum frequency of every SBD_SLEEP_TIME seconds.

The update is done only if the value for the CPU time, resident memory usage, or virtual memory usage has changed by more than 10 percent from the previous update or if a new process or process group has been created.

The LIM marks the host SBDDOWN if it does not receive the heartbeat in 1 minute. Therefore, setting SBD_SLEEP_TIME greater than 60 seconds causes the host to be frequently marked SBDDOWN and triggers mbatchd probe, thus slowing performance.

After modifying this parameter, use badmin hrestart -f all to restart sbatchds and let the modified value take effect.

Default

30 seconds.
