[Paraview] Tiled display with multi-gpu.

[Omkaranathan]

Thanks Ken,
But what I was searching for was the configuration options, as I 
couldn't find any information on how to launch the server in case of 
multiple displays.
Can I specify display numbers in machinefiles?
It would be great if I can get any pointers.
