the machine you are logged into. You can then start, stop,
and restart applications as usual.
From a terminal window started from the desktop, you
must use the vglrun command to launch OpenGL
applications, with the application pathname entered as a
parameter to the vglrun command.
To terminate your session, log out from your desktop
environment.
-g or --tile_geometry
Sets the tile geometry that each of the tiles uses. Valid
values include 1280x1024, 1400x1050, and 1600x1200.
This value overrides in order of precedence,
tile_geometry values set in the User Configuration File,
for the Display Surface itself in the Display Surface
declaration section of the Site Configuration File, or for the
entire cluster by means of the SVA_CLUSTER section of
Site Configuration File.
-v or --verbose
Provides additional debugging feedback to the screen as
the script runs.
-V or --version
Displays the version of this script.
-D or --debug
Turns on script debugging.
-u or --usage
Displays a brief usage message.
-h or --help
Displays Help for the script.
application_command
Site-specific application command.
Returns
None.
Description
This command launches a fully functional Bash shell script to run an application on a single node
in the SVA. It is designed to use TurboVNC to control the application from a local desktop. The
command is on your PATH.
The script allocates cluster resources, launches necessary ancillary applications (for example, the
X Servers and the TurboVNC Server), runs the application on the appropriate node, and terminates
the application at the end of the session.
You can also use this command in interactive mode to launch applications. Once the desktop
environment appears in interactive mode, you can create icons to launch an application. Refer
to the SVA Users Guide for more information on running the TurboVNC script in interactive
mode.
This command launches your application by requesting and allocating a visualization node
(render or display) to the job. You have several options for indicating how you want a node
allocated:
• You can accept the default node assigned by the script. The script draws the node from the
pool of render nodes. If there are no render nodes available, then the script chooses a node
from the pool of available display nodes, unless you have specifically indicated via the
command line using -R that you do not want to use a display node.
• You can use the -d option to specify an existing Display Surface or a remote node name
that uses a single tile. Its display node is allocated to take care of display functions and the
images appear simultaneously on your local desktop and on the SVA cluster's display device.
The execution host node defined for the Display Surface runs your application. The
SVA_EXECUTION_HOST value for the Display Surface is specified in the Configuration Data
