IBM Spectrum LSF 10.1 Fix 454701 Readme File
Abstract
P102234. This fix prevents a child scheduler from crashing when the scheduler binary file is a compiler optimization binary file.
Description
Readme documentation for IBM Spectrum LSF 10.1 Fix 454701 including installation-related instructions, prerequisites and co-requisites, and list of fixes.
This fix addresses the following issue:
When the scheduler binary file is obtained from compiler optimization, the child scheduler might crash. This is because the child scheduler uses a function that might cause a core dump under a specific case, but the child scheduler normally checks for this case before running the function to prevent the core dump. The compiler optimization removes this check, which causes the child scheduler to run the function regardless of the circumstances and potentially cause a core dump. This fix restores the check to prevent the function from running and causing a core dump.
