HP Scalable Visualization Array Version 1.1 Visualization System Software Reference Guide

1 Main Areas of the VSS
There are several categories of Visualization System Software (VSS) that help you get an application running
on an HP Scalable Visualization Array (SVA). In addition, there are job launch scripts and script templates
that help you run applications on the SVA. This chapter provides an overview of these functions and
commands.
Configuration Data Utility
The svaconfigure Configuration Data Utility creates or redefines the Site Configuration File in the event
that a node is added or removed from the cluster, or if the cluster is re-imaged with operating system or VSS
software kits.
Refer to the HP SVA User's Guide for an overview of the use of Configuration Data Files to launch visualization
applications. Refer to the HP SVA System Administration Guide for details on the format and content of the
data files and how to customize them for your environment.
Scripts, Functions, and Environment Variables
Script templates are scripts that require site-specific editing before you can use them to run visualization jobs
on an SVA. There are several templates you can use, depending on the type of visualization application
you run.
There are also fully functioning job launch scripts that typically do not require editing.
The templates and fully functioning scripts are discussed in the HP SVA User's Guide . Chapter 2 of this
document contains reference information on the different templates and scripts. The same reference information
is available as manpages on all SVA nodes.
There are a number of Configuration Data Access functions used in the templates and scripts. For example,
functions that make it possible to put and get data to and from the Configuration Data Files. This
configuration information is necessary when you launch visualization applications on the cluster. You can
also use these functions in the launch scripts, and in your application to get system configuration information
and to put values that are used as part of the visualization job execution. These functions use a C style of
calling standard, which you should bear in mind if you intend calling them from your application.
There is also a set of Data Access environment variables that are defined using values from the Configuration
Data Files. You can use these environment variables in job launch scripts, in combination with the
Configuration Data Access functions. See Table 2-1 for the list of variables.
