IBM Spectrum LSF 10.1 Fix 528106 Readme File 

Abstract

P103158. This fix enables the main mbatchd daemon to directly handle bread/bstatus command requests, instead of forking a child to handle these requests.

Description

Readme documentation for IBM Spectrum LSF 10.1 Fix 528106 including installation-related instructions, prerequisites and co-requisites, and list of fixes.

This fix addresses the following issue:

In large cluster where the mbatchd memory is large, forking a child to handle bread/bstatus command requests would slow down mbatchd performance. After this fix, the main mbatchd daemon directly handles bread/bstatus command requests, instead of forking a child to handle these requests.
