HP XC System Software Administration Guide Version 3.2

16 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.
