Supplementary Information

This section contains links to third-party and open source components that are integrated into the HP XC System Software core technology. In the HP XC documentation, except where necessary, references to third-party and open source software components are generic, and the XC adjective is not added to any reference to a third-party or open source command or product name. For example, the SLURM srun command is simply referred to as the srun command.

•http://www.platform.com

Home page for Platform Computing Corporation®, the developer of the Load Sharing Facility ( LSF, the batch system resource manager used on an HP XC system, is tightly integrated with the HP XC and SLURM software.

For your convenience, the following Platform LSF-HPC documents are shipped on the HP XC Documentation CD in PDF format:

•Administering Platform LSF

•Administration Primer

•Platform LSF Reference

•Quick Reference Card

•Running Jobs with Platform LSF

LSF-HPC procedures and information supplied in the HP XC documentation supersedes the information supplied in the LSF documents from Platform.

The Platform LSF manpages are installed by default. The lsf_diff(7) manpage, supplied by HP, describes LSF command differences on an HP XC system.

See the following sources for more information about LSF-HPC:

•LSF-HPC administrator tasks are documented in the HP XC System Software Administration Guide.

•LSF-HPC user tasks such as launching and managing jobs are documented in the HP XC System Software User's Guide.

•To view LSF HPC manpages supplied by Platform Computing Corporation, use the following command:

$ man lsf_command_name

•The LSFAdministrator and Reference guides developed by Platform are also available at: http://www.hp.com/techservers/clusters/xc_clusters.html

•http://www.llnl.gov/LCdocs/slurm/

Home page for the Simple Linux Utility for Resource Management (SLURM), which is integrated with LSF-HPC to manage job and compute resources on an HP XC system.
