Render Nodes
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
