IBM Spectrum LSF 10.1 Fix 482689 Readme File

Abstract

P102440. This fix improves the accuracy of CPU time accounting.

Description

Readme documentation for IBM Spectrum LSF 10.1 Fix 482689 including installation-related instructions, prerequisites and co-requisites, and list of fixes.

This fix addresses the following issue:

1 Up to n * SBD_SLEEP_TIME seconds of cpu time is lost in LSF reporting.

2 All LSF accounting files, (such as lsb.events, lsb.acct, and lsb.stream) have incorrect values for user time and system time. The user time is recorded as the total cpu time, and system time is recorded as zero, which are both incorrect.

The second issue is fixed by the introduction of a new parameter, LSB_CPUACCT_STAT in lsf.conf. To separate cpu time and system time, configure "LSB_CPUACCT_STAT=Y" in lsf.conf. The default value is N.
