5. Installation and configuration

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 before 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
