HP XC System Software Administration Guide Version 3.2

2. Rerun the cluster_config utility. Proceed through the process until you reach the LSF
section.
3. When you are prompted to configure LSF, enter yes.
4. When prompted, select the type of LSF you want to install:
• Standard LSF-HPC is choice 1.
• LSF-HPC with SLURM is choice 2, the default.
5. When prompted, enter d to delete the existing LSF installation.
6. Answer the remainder of the questions as appropriate for your system. The
cluster_config updates the golden image.
7. Propagate the new golden image to all nodes. See Chapter 11 (page 139) for more information.
16.4 LSF-HPC with SLURM Installation
When selected, LSF-HPC with SLURM is automatically installed during cluster_config
execution. This installation is optimized for operational scalability and efficiency within the HP
XC system, and is a very good solution for the HP XC system. Depending how you manage your
overall LSF cluster file system, this installation is sufficient for adding the HP XC system to an
existing LSF cluster. For more information, see “Installing LSF-HPC with SLURM into an Existing
Standard LSF Cluster ” (page 289).
The LSF-HPC with SLURM tar files to be installed are located in the /opt/hptc/lsf/files
directory. Before the installation begins, you are prompted for the following information:
• Primary LSF administrator
This user account is necessary for establishing ownership of the LSF-HPC with SLURM
configuration file. If the lsfadmin user account does not exist, it will be created locally
within HP XC. You can configure other LSF administrators after the installation has
completed. For more information, see Administering Platform LSF on the HP XC
Documentation CD.
• The name of the LSF cluster
This name must be unrelated to any network host name. This name must be unique unless
the intent is to add the HP XC system to an existing LSF cluster. In such a case, the name
must match the name of the existing LSF cluster.
The default name is hptclsf.
After these values are obtained and verified, the LSF-HPC with SLURM installation runs installing
the appropriate files under /opt/hptc/lsf/top/. On completion, the following post-installation
procedures are performed:
• LSF-HPC with SLURM directories are relocated to take advantage of the HP XC file system
hierarchy.
The location of the LSF-HPC with SLURM installation is /opt/hptc/lsf/top, which
contains four directories:
conf The conf directory is moved to /hptc_cluster/lsf/conf; it is linked through
a soft link to /opt/hptc/lsf/top/conf.
work The work directory is moved to /hptc_cluster/lsf/work; it is linked through
a soft link to /opt/hptc/lsf/top/work.
log The log directory is moved to /var/lsf/log; it is linked through a soft link to
/opt/hptc/lsf/top/log.
This ensures that all LSF-HPC with SLURM logging remains local to the node
currently running LSF-HPC with SLURM.
6.2 This directory remains in place and is imaged to each node of the HP XC system.
• The SLURM resource is added to the configured LSF execution host
