HP XC System Software Administration Guide Version 3.1

15 Managing LSF
The Load Sharing Facility (LSF) from Platform Computing Corporation is a batch system resource manager
used on the HP XC system. LSF is an integral part of the HP XC environment.
On an HP XC system, a job is submitted to LSF, which places the job in a queue and allows it to run when
the necessary resources become available. In addition to launching jobs, LSF provides extensive job
management and information capabilities. LSF schedules, launches, controls, and tracks jobs that are
submitted to it according to the policies established by the HP XC site administrator.
Two types of LSF are available for installation on the HP XC:
• Standard LSF-HPC
This product is the popular batch system produced by Platform Computing Corporation that has
become an industry standard.
For full information about Standard LSF-HPC, refer to the standard LSF documentation set, which
is described in the “Related Software Products and Additional Publications” section of this document.
LSF manpages are also available online on the HP XC system.
• LSF-HPC with SLURM
This product is the High Performance LSF product from Platform Computing Corporation and has
been integrated with SLURM to take advantage of SLURM's scalable, efficient resource management
and parallel job support.
The intended primary use of the HP XC system determined which of these LSF products was installed.

For your convenience, the HP XC Documentation CD contains LSF Version 6.2 documentation from
Platform Computing.
15.1 Standard LSF-HPC
Most topics are covered in the LSF documentation from Platform Computing and are not addressed in
detail in this document.
Standard LSF-HPC is installed and configured on all nodes of the HP XC system by default.
The LSF RPM places the LSF tar files from Platform Computing in the /opt/hptc/lsf/files/lsf/
directory. Standard LSF-HPC is installed, during the operation of the cluster_config utility, in the
/opt/hptc/lsf/top directory. On completion, the conf and work directories are moved to
/hptc_cluster/lsf directory to ensure:
• A single set of Standard LSF-HPC configuration files for the HP XC system
• One common working space for preserving and accessing accounting and event data.
