IBM Platform LSF 9.1.3 Fix 381760 Readme File

Abstract

P101530. Fix to reduce the unnecessary time spent on hosts filtering during each scheduling session, if the MC_PLUGIN_UPDATE_INTERVAL parameter is defined in an execution cluster in MultiCluster job forwarding mode.

Description

Readme documentation for IBM Platform LSF 9.1.3 Fix 381760 including installation-related instructions, prerequisites and co-requisites, and list of fixes.

This fix addresses the following issue:

When the execution cluster defines the MC_PLUGIN_UPDATE_INTERVAL parameter in lsb.params and defines several receive queues in lsb.queues, it takes much unnecessary time on hosts filtering during each scheduling session if the average number of hosts in the host lists of all receive queues defined by HOSTS in lsb.queues is large.
