HP SVA V2.1 System Administration Guide

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 /hptc_cluster/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 Myrinet can be
used for the System Interconnect to speed the transfer of image data and drawing commands
to the visualization nodes.
tile The image output from a single port of a graphics card in a display node. Typically, a tile is
also considered the image displayed on a single display device such as a flat panel or projector.
UBB Utility Building Block (UBB). Base utility unit of a modular expandable SVA system.
UVB Utility Visualization Block (UVB): Base utility unit of a bounded physical SVA configuration.
