HP Scalable Visualization Array (SVA) Software manual Hptccluster/sva/job/id.conf. This file has

	arrangement of the display blocks. Invoked using the
	svadisplaysurface command. Requires root privileges.
DMX	Distributed Multi-Head X is a proxy X Server that provides
	multi-head support for multiple displays attached to different
	machines (each of which is running a typical X Server).
interactive session	A visualization session typically launched using a VSS
	script provided by HP. Such a script allocates the cluster
	resources, and starts the X Servers. It also starts a desktop
	environment (for example, KDE or Gnome) from which you
	can launch your applications repeatedly while retaining
	the same job resources. To launch your application, open
	a terminal window and then run your application as usual.
Job Settings File	A Configuration Data File that determines the way in which
	a visualization job runs. The visualization job data is
	defined at job allocation time from options specified to the
	job launch scripts, from data access calls embedded in
	the script, and the other configuration data files. The Job
	Settings File is named
	/hptc_cluster/sva/job/<id>.conf. This file has
	a life span equal to that of the job.
LSF	Platform Load Sharing Facility for High Performance
	Computing. 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.
Node Configuration Tool	Defines the display block output from a single display
	node, including the relative spatial arrangement of the
	tiles. Invoked using the svaconfigurenode command.
	Requires root privileges.
ParaView	An open-source, multi-platform, extensible application
	designed for visualizing large datasets. This scalable
	application runs on single-processor workstations as well
	as on large parallel supercomputers.
Remote Graphics Software (HP)	HP RGS is an HP product that facilitates access to cluster
	workstations from offices over a standard ethernet network.
	Optional purchase. Script support is provided in the SVA
	Kit for this product.
render node	A type of visualization node used to render images. A
	visualization job uses multiple nodes to render image data
	in parallel. A render node typically communicates over
	the System Interconnect with other render and display
	nodes to composite and display images. Requires a NIC
	if used with HP RGS.
Site Configuration File	A Data Configuration File. This file contains the default
	system settings and Display Surface definitions. It is
	generated initially by HP (and a site administrator if
	necessary) using the svaconfigure Utility when the
	cluster software is installed. Only root users can change
	this file. This file is named /opt/sva/etc/sva.conf.
SLURM	Simple Linux Utility for Resource Management. A resource
	manager for Linux clusters. Used to set up visualization
	sessions and launch visualization jobs. Preferred allocation
	utility of HP XC.
svaconfigure Utility	Generates the Site Configuration Data file.
System Interconnect	The System Interconnect (SI) supports data transfer among
	HP XC cluster nodes, including visualization nodes.
	High-speed, low-latency networks such as InfiniBand and
