Readme File for IBM® Spectrum LSF 10.1 Fix 601094
Abstract
P104623. This fix:
1. Supports gpu_driver as a filter option in the following commands bhosts/bsub/lshosts.
2. Prevents lim from core dump on GPU hosts when LSF management host failover.
Description
Readme documentation for IBM® Spectrum LSF 10.1 fix 601094 including installation-related instructions, prerequisites and co-requisites, and list of fixes.
This fix addresses the following issue:
1. Currently, when the GPU resources have the following configurations:
LSF_GPU_AUTOCONFIG is set to Y
LSB_GPU_NEW_SYNTAX is set to extend
LSF_GPU_RESOURCE_IGNORE is set to Y
The gpu_driver option cannot be used to filter Nvidia GPU hosts in -R option of lshosts, bhosts, or bsub commands. After you apply this fix, the gpu_driver can now select Nvidia GPU hosts from the -R option of lshosts, bhosts, or bsub commands.
2. The lim daemons on GPU hosts core dump when LSF management host failover.

5. Installation and configuration
5.1 Before you install
(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 management host as root
4) Set the LSF cluster environment:
- For csh or tcsh: % source LSF_TOP/conf/cshrc.lsf
- For sh, ksh, or bash: $ . LSF_TOP/conf/profile.lsf
5.2 Installation steps
1) Go to the fix install directory: cd $LSF_ENVDIR/../10.1/install/
2) Copy the fix file to the install directory $LSF_ENVDIR/../10.1/install/
3) Run patchinstall: ./patchinstall <fix>
5.3 After you install
1) Log on to the LSF management host as the LSF cluster primary administrator and set the LSF cluster environment
2) Run lsadmin limrestart all
5.4 Uninstallation
1) Log on to the LSF management host as root and set the LSF cluster environment
2) Go to the fix install directory: cd $LSF_ENVDIR/../10.1/install/
3) Run ./patchinstall -r <fix>
6. List of files
