Readme file for IBM® Spectrum LSF 10.1 Fix 601517
Abstract
P104853. 1). Enable high priority GPU jobs to pre-empt multiple low priority GPU jobs in default mode. 2). prevent bhosts -gpu from causing child mbatchd to core dump
Description
Readme documentation for IBM Spectrum LSF 10.1 Fix 601517 including installation-related instructions, prerequisites and co-requisites, and list of fixes.
This fix addresses the following issues:
1) Currently, high priority GPU jobs cannot pre-empt multiple low priority GPU jobs if they are running on the same GPU with default (shared) mode. This fix removes the limitation if the high priority GPU job is submitted with j_exclusive the setting, or is set to exclusive_process mode.
2) bhosts -gpu causes child mbatchd to core dump.

2.
Starting from LSF 10.1 Fix Pack 13, the default values
of the following three GPU parameters are changed to:
LSF_GPU_AUTOCONFIG=Y
LSB_GPU_NEW_SYNTAX=extend
LSF_GPU_RESOURCE_IGNORE=Y
If you have installed Fix Pack 13, no further action is
needed to set these parameters. If you have installed Fix Pack 12 or earlier,
consider explicitly configuring the same values to these three parameters:
LSF_GPU_AUTOCONFIG=N
LSB_GPU_NEW_SYNTAX=N
