Follow these steps to run ParaView on the SVA. You can use a script to carry out these steps.

1.Allocate the render and display nodes on the SVA that act as the ParaView Render Servers. Specify a named Display Surface to allocate the display device you intend to use.

Tip

You can use a SLURM srun command to do this.

2.Launch X Servers on all the allocated nodes.

3.Launch the ParaView Client on the Execution Host. When launching the Client, set the DISPLAY environmental variable to your local desktop in order to push the Client display to that machine. You also need to set the ParaView launch command option to listen mode. See the ParaView documentation for details on syntax.

4.Use a command to launch the ParaView Render Servers on the allocated nodes. This launch command must also specify the node location of the ParaView Client (the Execution Host). Specify the name of the Execution Host using its ic-name, which forces communication between the ParaView Render
