[Paraview] pvrenderserver with MPI or without MPI?

[Berk Geveci]

Hi Shigenobu,

I'd recommend using simple client-server and turning off remote
rendering from the Preferences -> Render View -> Server. This should
give you the same result without the complication of the render
server. Making use of multiple cores when there is only one graphics
card is a research topic for us. In the future, there will be better
way of doing this.
