HP XC System Software Administration Guide Version 3.2

• HP OEM licensing is configured.
HP OEM licensing is enabled in LSF-HPC with SLURM by adding the following string to
the configuration file, /opt/hptc/lsf/top/conf/lsf.conf. This tells LSF-HPC with
SLURM where to look for the shared object to interface with HP OEM licensing.
XC_LIBLIC=/opt/hptc/lib/libsyslic.so
• Access to LSF-HPC with SLURM from every node in the cluster is configured.
Configuring all nodes in the HP XC system as LSF-HPC with SLURM floating client nodes
makes available access to LSF-HPC with SLURM from all nodes. Two files are edited to
perform this configuration:
— Adding LSF_SERVER_HOSTS="lsfhost.localdomain" to the lsf.conf
configuration file.
— Adding FLOAT_CLIENTS_ADDR_RANGE=172.20 on its own line in the Parameters
Section of the file /opt/hptc/lsf/top/conf/lsf.cluster.clustername.
The FLOAT_CLIENTS_ADDR_RANGE value (in this case 172.20) must be the management
network IP address range that is configured for the HP XC system. This value should
equal the value of nodeBase in the /opt/hptc/config/base_addr.ini file .
The HP XC system /etc/hosts file has an entry for lsfhost.localdomain, which
allows the LSF-HPC installation to install itself with the name lsfhost.localdomain.
The /opt/hptc/lsf/top/conf/hosts file maps lsfhost.localdomain and its virtual
IP to the designated LSF execution host
• An initial LSF-HPC with SLURM hosts file to map the virtual host name
(lsfhost.localdomain) to an actual nodename is provided.
• Sets the default LSF-HPC with SLURM environment for all users who log into the HP XC
system.
Files named lsf.sh and lsf.csh are added to the /etc/profile.d/ directory; these
files source the respective /opt/hptc/lsf/top/conf/profile.lsf and
/opt/hptc/lsf/top/conf/cshrc.lsf files.
• The JOB_ACCEPT_INTERVAL= entry in the lsf.params file is set to 0 (zero) to allow more
than one job to be dispatched to the LSF execution host per dispatch cycle. If this setting is
nonzero, jobs are dispatched at a slower rate.
• A soft link from /etc/init.d/lsf to /opt/hptc/sbin/controllsf is created.
• A scratch area for LSF-HPC with SLURM is created in the /hptc_cluster/lsf/tmp/
directory. It must be readable and writable by all.
• The controllsf set primary command is invoked with the highest-numbered node
that has the resource management role. If this is not done, LSF-HPC with SLURM starts on
the head node even if the head node is not a resource management node.
16.5 LSF-HPC with SLURM Startup and Shutdown
This section discusses starting up and shutting down LSF-HPC with SLURM.
16.5.1 Starting Up LSF-HPC with SLURM
LSF-HPC with SLURM is configured to start up automatically when the HP XC system starts
up, through the use of the /etc/init.d/lsf script.
If LSF-HPC with SLURM stops running, you can start it with the controllsf command, as
shown here:
# controllsf start
This command searches through a list of nodes with the lsf service until it finds a node to run
LSF-HPC with SLURM.
