HP SVA V2.1 Visualization System Software Reference Guide

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

See the sva_vgltvnc.sh manpage and the SVA Users Guide for an example of using the

ParaView script remotely via TurboVNC.
