IBM® Spectrum LSF 10.1 Fix 601163 Readme File

Abstract

P104684. This fix:

1. Prevents the mbschd daemon core dumps when array jobs were submitted to fairshare queues and hierarchy of user group changed.

2. Prevents the mbatchd daemon core dumps if job command was long when job got canceled.

Description

Readme documentation for IBM® Spectrum LSF 10.1 Fix 601163 including installation-related instructions, prerequisites and co-requisites, and list of fixes.

This fix addresses the following issue:

1. When array jobs are submitted to fairshare queues and the bconf command or egroup executable causes hierarchy of user group to change, the mbschd daemon will randomly core dump.

2. When a job command is longer than 2048 seconds and the job got canceled, the mbatchd daemon will core dump.

5. Installation and Configuration

5.1 Before installation

(LSF_TOP=Full path to the top-level installation directory of LSF.)

1) You must have LSF 10.1 Fix Pack 12 installed prior to installing this fix. Download this fix pack from IBM Fix Central (https://www.ibm.com/support/fixcentral) and search for build600488. Contact IBM LSF Support if you have any questions or problems with installing fix pack 12.

2) Starting in IBM Spectrum LSF Version 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 fix pack 13 installed, no further action is needed to set these parameters . If you have IBM Spectrum LSF Version 10.1 Fix Pack 12 or earlier, consider explicitly configuring the same values to these three parameters.

If you want to keep the former GPU behavior, and any one of the three parameters are missing in the lsf.conf configuration file, you must explicitly configure the following default settings that are defined in fix pack 12 or earlier:
LSF_GPU_AUTOCONFIG=N
LSB_GPU_NEW_SYNTAX=N
LSF_GPU_RESOURCE_IGNORE=N

3) Log on to the LSF master host as root

4) Set the LSF cluster environment:

- For csh or tcsh: % source LSF_TOP/conf/cshrc.lsf
