IBM Platform LSF 9.1.3 Fix 379428 Readme File

Abstract

P101511. This fix reduces the pim reply time when sbatchd call PIM. If the previous PIM update to the pim.info file was more than the LSF_CALL_PIM_SELET_TIMEOUT value in seconds (default is 10 seconds), PIM replies to the next sbatchd call firstly before update pim.info to reduce sbatchd hanging time.

Description

Readme documentation for IBM Platform LSF 9.1.3 Fix 379428 including installation-related instructions, prerequisites and co-requisites, and list of fixes.

This fix addresses the following issue:

If cgroup is disabled, and you submit plenty of jobs, sbatchd calls to PIM might take over 10 seconds, which then time out and retry 3 times for each call. These multiple attempts result in sbatchd hanging and blocking communications between mbatchd and sbatchd.
