HP XC Clustering Software

The SVA runs HP XC System Software Version 3.0 clustering software. The SVA uses HP XC for the following key system management tasks:

•Installing and reinstalling a uniform set of software on visualization nodes.

•Booting and shutting down the cluster.

•Managing user accounts and user directories across the cluster.

•Naming each of the nodes in the cluster and determining which nodes are up and running.

•Serializing application use of the cluster.

For more information on HP XC, consult the HP XC documentation set at the following Web site: http://docs.hp.com/en/6093/index.html

Table 3-2summarizes the software components that are provided by the HP XC operating system that relate to the SVA.

Notes

Simple Linux Utility for Resource Management (SLURM)

Platform Load Sharing Facility for High Performance Computing (LSF HPC)

SystemImager

pdsh

HP-MPI

HP Scalable File Share (HP SFS)

FlexLM®

A resource manager for Linux clusters. Used to set up visualization sessions and launch visualization jobs. Preferred allocation utility of HP XC.

Layered on top of SLURM to provide high-level scheduling services for the HP XC system software user. LSF can be used in parallel with SVA job launching techniques that rely on SLURM.

System file replication used to install cluster nodes.

A parallel distributed shell that replaces rsh and ssh.

Message Passing Interface.

High performance file system (optional). License management.
