5. Installation and configuration

Before you install

LSF_TOP is the full path to the top-level installation directory of LSF.

1. Before you apply this fix make sure that you installed LSF 10.1 Fix Pack 12 or later.

2. Starting in 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 Fix Pack 13 installed, and these GPU parameters are not configured in the lsf.conf configuration file, the default values will be used, and the parameters already configured in the lsf.conf file will not be affected.

If you want to keep the former GPU behavior, and if any 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. If you are using the lsfd.service file from Fix Pack 14 or the Fix build601849, make sure you install the Fix build602067. You can download the LSF fix from https://www.ibm.com/support/fixcentral.
