Installing Standard LSF on HP XC

Preparing to install standard LSF
You can install standard LSF on XC in place of SLURM and LSF-HPC. This procedure removes SLURM
and LSF-HPC and configures standard LSF daemons on every compute node in the XC cluster.
Prerequisites
The following software is needed to install standard LSF on XC:
• The appropriate standard LSF binary tar file. For XC v2.n this is as follows (where X.Y is the
selected LSF version, such as 6.1):
• lsfX.Y_linux2.4-glibc2.3-ia64.tar.Z for an XC6000 Itanium-based system.
• lsfX.Y_linux2.4-glibc2.2-amd64.tar.Z for an XC4000 Opteron-based system.
• lsfX.Y_linux2.4-glibc2.3-ia32e.tar.Z for an XC3000 64-bit Intel-based system
• The corresponding standard LSF installation tar file, lsfX.Y_lsfinstall.tar.Z.
• A standard LSF license file from Platform, appropriately licensed for the total number of CPUs on
your XC cluster.
The procedure makes the following assumptions about your system:
• LSF is only to be installed on XC nodes. To extend the LSF configuration outside of XC to include
non-XC nodes is beyond the scope of this document.
• All nodes are up and running, so that they can be updated with the changes described in this
procedure. If there are nodes that are down, you will need to ensure that those nodes are
updated as soon as they come online again.
Removing or disabling SLURM and LSF-HPC for
SLURM
Use the following procedure to remove SLURM and LSF-HPC, and set up standard LSF to automatically
start at boot time on every cluster compute node.
1. Remove the SLURM and LSF-HPC cluster configuration scripts.
Remove these scripts to prevent further cluster maintenance activities from attempting to
reconfigure and re-enable SLURM and LSF-HPC. Use the following commands:
root@n16 root]# cd /opt/hptc/etc/gconfig.d/
[root@n16 root]# rm -f C55lsf C50slurm_controller
[root@n16 root]# cd /opt/hptc/etc/nconfig.d/
[root@n16 root]# rm -f C55lsf C51slurm_compute C51slurm_controller
Do not delete the *slurm_launch link in the /opt/hptc/etc/nconfig.d/ directory. (See
the next step.)
