You have to be using the nightly release.

Once you configure --with-mpi,  you can use MPI directly or you can use the 
vtkMultiProcessController interface.

You can also use the ports (vtkInputPort and vtkOutputPort) initially 
developed by Jim Ahrens.  These allow you to connect pipelines in different 
processes.
