HP SVA V2.1 Visualization System Software Reference Guide

-f or --framelock
Enables hardware framelock on any Display Surface for
jobs.
Requires an NVIDIA framelock-capable graphics card and
the NVIDIA Quadro G-Sync option card installed.
-v or --verbose
Provides additional debugging feedback to the screen as
the script runs.
-V or --version
Displays the version of this script.
-h or --help
Displays Help for the script.
Returns
None.
Description
This command launches a Bash shell job script to run the distributed EnSight application. The
script is located in the /opt/sva/bin directory.
The script allocates cluster resources, launches necessary ancillary applications (for example, the
X Servers), runs the application on the right nodes, and terminates the application at the end of
the session.
EnSight supports multiple kinds of distribution:
• Using multiple nodes to extract features from a dataset.
EnSight refers to this feature as server-of-servers (sos). The EnSight client sees one server,
namely, the server of servers. However, this server has distributed its work over other server
nodes.
• Displaying on a multi-tiled display driven by more than one node.
EnSight refers to this feature as Virtual Reality mode (VR).
• Using multiple graphics cards on multiple nodes to produce an image displayed by a single
graphics card.
EnSight refers to this feature as Distributed Rendering mode (DR).
• Any combination of the three configurations.
For example, using the appropriate command options, you could use sos, vr, and dr all
in one session.
The EnSight script launches the EnSight Client (GUI) on the node where the script is run. SVA
often refers to this as –local mode. When run, the script finds the appropriate resources on the
cluster to support a request. After finding the resources, the script creates the necessary
configuration files (located in /tmp/ensight…) and launches EnSight using these configuration
files. Note that SOS requires compute nodes; DR requires render nodes; and VR requires display
nodes. Because feature extraction occurs before any image rendering, the script uses DR render
nodes for feature extraction.
The script launches EnSight in the desired configuration. Once the EnSight client is running, you
can load your model.
In addition to starting the session and launching the sample application, the sva_ensight82.sh
script also terminates X and cleans up the session when the program is done.
Note that the EnSight application itself is not included as part of the SVA Kit.
Example
The following command launches the EnSight application using a site-specific Display Surface
called 3_panel_display:
% sva_ensight82.sh --sos 5 --pipeline 2 --display_surface 3_panel_display
