HP Scalable Visualization Array Software - Manual (Page 57)

Host while its display is pushed back to your local desktop. HP recommends that you use
a Display Surface that uses a display node as its Execution Host.
The Execution Host is defined for each Display Surface. You specify the Display Surface by name
when launching a visualization job. The Execution Host for a Display Surface is the default
location for running an application. You can locate the default Execution Host by reading the
value for the SVA_EXECUTION_HOST tag in the Site Configuration File,
/hptc_cluster/sva/etc/sva.conf
. Each instance of a named Display Surface in the Site
Configuration File has an associated default Execution Host. You can override the default by
setting the SVA_EXECUTION_HOST tag in your User Configuration File to indicate which host
to use to run the application for a given Display Surface. See
Chapter 5 and the SVA System
Administration Guide for details on changing Configuration Data Files and their tag content.
Figure 6-2 shows the flow of control for the ParaView application when run on the SVA.
