[Paraview] Multiple servers

[David E DeMarle]

Sort of.

The point of using MPI is to establish a "virtual parallel machine".
The physical machines that comprise that virtual parallel machine can
all work together because they are part of the same mpi job. The
parallel filters within VTK that paraview uses are only written to
work with the other machines in the same mpi job.

I say sort of because it is possible to run paraview in a split server
mode, consisting of exactly  two virtual parallel machines. One
machine first does most of the visualization pipeline filtering work,
then the other does most of the rendering pipeline work. These are
referred to as pvdataserver and pvrenderserver respectively. Inside
each server communication happens over MPI and between the two servers
communication happens over TCP instead of MPI, as it does between the
servers and the client.

You can refer the the parallel processing section of the ParaView
user's guide for details.
