[Paraview] Parallel Help

[David E DeMarle]

When you say multiple servers what do you mean?

In ParaView the client establishes at most two connections at a time.
The usual case is when is connects to a program called pvserver, the
rarer case is when it connects to two programs, the pvrenderserver and
the pvdataserver.

The server or (the two) servers are usually, but not always, message
passing parallel programs that use  MPI to communicate between some
number of processes running copies of the same program. The binary
distributions of paraview are not built with MPI so to run the servers
as parallel programs you must compile from source.

An example of getting everything started is to:
mpirun -np 4 pvserver (this assumes you have built paraview with MPI)
run paraview
go to file connect
create a configuration that specifies where the server is running
connect to it
