IBM Platform LSF 9.1.3 Fix 394627 Readme File

Abstract

P101605. Fix to resolve jobs that have a long pending time with the following pending reason: "Recently released Cray compute node cannot be re-used at this moment".

Description

Readme documentation for IBM Platform LSF 9.1.3 Fix 394627 including installation-related instructions, prerequisites and co-requisites, and list of fixes.

This fix addresses the following issue:
Cray compute nodes may be unusable for a long period of time with the following pending reason: "Recently released Cray compute node cannot be re-used at this moment". LSF ensures that nodes are no longer reserved by ALPS before including them in another reservation request by keeping the released reservation until a failure is returned or a timeout takes effect. The timeout can be configured with a new parameter LSF_CRAY_RELEASE_TIMEOUT=time_seconds in lsf.conf (600 by default).
