HP SVA V2.0 Visualization System Software Reference Guide
This command launches your application by requesting and allocating visualization nodes to
the job. The display takes place on the Display Surface you specify as an option, and which is
specific to your cluster. The launch script takes care of running the various Chromium portions
(Mothership and Servers) on the display nodes. Where the master application and DMX run is
based on the SVA_EXECUTION_HOST value for the Display Surface, as specified in the
Configuration Data Files. You can determine this value by examining the Site Configuration File
/hptc_cluster/sva/etc/sva.conf.
The launched application is denoted by a site-specific application command.
The script also terminates X and DMX Servers and cleans up the session when the program is
done.
Important:
Before running the script in interactive mode, you must set the DISPLAY environment variable
to point to the machine on which you want the display to appear, or the script fails.
Example
The following command runs the OpenGL atlantis application on the FULL_DISPLAY Display
Surface using Chromium and DMX. The FULL_DISPLAY Display Surface was created using the
Display Surface Configuration Tool. See the SVA System Administration Guide for detailed
information on the Display Surface Configuration Tool.
The application command string is unique and site-specific.
% sva_chromium_dmx.sh -d FULL_DISPLAY "/usr/X11R6/lib/xscreensaver/atlantis"
The following command runs the atlantis application on the FULL_DISPLAY Display Surface.
Note the use of the application-specific command line parameter -count 20.
% sva_chromium_dmx.sh -d FULL_DISPLAY /
"/usr/X11R6/lib/xscreensaver/atlantis -count 20"
The following command initiates an interactive session:
% sva_chromium_dmx.sh -d FULL_DISPLAY -I
The previous interactive command allocates resources for an interactive mode of operation. You
can launch regular X applications as normal. For OpenGL applications such as atlantis, you
must use the command a second time, with only the application pathname and any
application-specific parameters:
% sva_chromium_dmx.sh "/usr/X11R6/lib/xscreensaver/atlantis"
