IBM Platform LSF 9.1.2 Fix 358404 Readme File

Abstract

P101343. Decouple JOB_ACCEPT_INTERVAL and MBD_SLEEP_TIME

Description

Readme documentation for IBM Platform LSF 9.1.2 Fix 358404 including installation-related instructions, prerequisites and co-requisites, and list of fixes.

This fix addresses the following issue:

Calculating JOB_ACCEPT_INTERVAL based on MBD_SLEEP_TIME to determine job accept interval can cause jobs to remain pending because a job just started recently. This solution decouples JOB_ACCEPT_INTERVAL and MBD_SLEEP_TIME. To set a specific job accept interval that is not based on MBD_SLEEP_TIME, specify an optional unit for the JOB_ACCEPT_INTERVAL value.

JOB_ACCEPT_INTERVAL
Syntax
JOB_ACCEPT_INTERVAL=integer[S|s|M|m]
Description
S|s means seconds.
M|m means minutes.

If you set a unit, the value you specify determines how long to wait after dispatching a job to a host before dispatching a second job to the same host.

If you do not set a unit, the value you specify is multiplied by the value of lsb.params MBD_SLEEP_TIME (60 seconds by
default). The result of the calculation is the number of seconds to wait after dispatching a job to a host,
before dispatching a second job to the same host.

See the IBM Platform LSF Configuration Reference for detailed information about JOB_ACCEPT_INTERVAL in lsb.params/lsb.queues.
