LSF_PIM_SLEEPTIME_UPDATE

Syntax

LSF_PIM_SLEEPTIME_UPDATE=y | n

Description

UNIX only.

Use this parameter to improve job throughput and reduce a job’s start time if there are many jobs running simultaneously on a host. This parameter reduces communication traffic between sbatchd and PIM on the same host.

When this parameter is not defined or set to n, sbatchd queries PIM as needed for job process information.

When this parameter is defined, sbatchd does not query PIM immediately as it needs information; sbatchd only queries PIM every LSF_PIM_SLEEPTIME seconds.

Limitations

When this parameter is defined:
  • sbatchd may be intermittently unable to retrieve process information for jobs whose run time is smaller than LSF_PIM_SLEEPTIME.
  • It may take longer to view resource usage with bjobs -l.

EGO parameter

EGO_PIM_SLEEPTIME_UPDATE

Default

Set to y at time of installation. Otherwise, not defined.
