IBM Spectrum LSF 10.1 Fix 490375 Readme File 

Abstract

P102557. This fix prevents LSF PIM from reporting inaccurate job memory usage.

Description

Readme documentation for IBM Spectrum LSF 10.1 Fix 490375 including installation-related instructions, prerequisites and co-requisites, and list of fixes.

This fix addresses the following issue:

When LSF_PIM_LINUX_ENHANCE is enabled, the memory usage reported by PIM might be inaccurate, especially for long running jobs. 

To resolve this issue, LSF PIM can read the smaps file of the process more frequently to update the job shared memory usage.

The following parameter enables this behavior:

LSF_PIM_SMAPS_UPDATE = Y

When enabled, the LSF PIM is more frequent on reading the smaps file of the process to update the job shared memory usage. This way, the job’s memory usage is more accurate and up to date. However, enabling this behavior means that the PIM might use more CPU than before. 

Default: N.
