HP Scalable Visualization Array Version 1.1 Visualization System Software Reference Guide

In addition to starting the session and launching the sample application, the sva_paraview.sh script also
terminates X and cleans up the session when the program is done.
Important
This series of steps is needed because of the way ssh and MPI interact.
Before using the sva_paraview.sh script for the first time, you must ssh to the all the nodes in the cluster,
or the script fails. When you access each node with ssh, you must do so twice by using each of the two
names used by the nodes for each network. That is, the Administration network uses the base node name,
for example, viz6; the System Interconnect uses the base node name with the ic- prefix, for example,
ic-viz6. To avoid problems, ssh to all the visualization nodes in the cluster, including the head node,
and then execute the script. You only need to ssh to the nodes this way one time.
The HP XC system supports the use of standard Modules commands to load and unload modulefiles that
are used to configure and modify the user environment. Before you start the sva_paraview.sh script, run
the following bash command when running as root:
% unset XAUTHORITY
Then run the module load command.
% module load mpi/hp
Note that ParaView is not included as part of the SVA Kit.
Example
The following commands set up the environment to use the ParaView launch script, and to launch the
application using six visualization nodes:
% unset XAUTHORITY
% module load mpi/hp
% sva_paraview.sh --display-surface SVA_DS_1_1 --render 6 --verbose
