[Paraview] Each Render node must connect to a display device?

[David E DeMarle]

If the data and render servers are running on the same nodes, do you need to
run them separately? pvserver will be more efficient if you do not because
it uses pointer references instead of serialization over TCP between the
data processing and rendering algorithms.

As for your question, if you want the server to take part in rendering, it
needs either X11 or OSMesa in order to render. If you use OSMesa, use the
--use-offscreen-rendering argument on the server.

If the data is small enough that the client can render it all, you do not
need the renderserver part at all. In this case run pvserver with
--disable-composite or go to preferences->render view->server and uncheck
remote render threshold to prevent paraview from trying to do any rendering
on the server.
