[Paraview] Distributed and parallel processing

[David E DeMarle]

Hi Patricia,

When you run paraview(in 2.x) or pvserver(2.x or 3.x) though MPI, the
servermanager makes sure that when your reader is instantiated, one copy is
started for every processor in the MPI group. The portion of the data that
each copy is responsible for reading is a function of its process rank. The
way that is done is to look at the request information to find what
pieces/extents it is needs to produce.

Looking at VTK/Parallel/vtkPDataSetReader.cxx may be helpful.

cheers
Dave DeMarle
