[Paraview] Non parallel filters under MPI

[Jorge Gerardo Peña Pastor]

Hi,

I'm working on a seed connectivity filter for Paraview. It works as
expected when executed with only one server node. Nevertheless, when I
try to execute it in several nodes with mpi + pvserver, it doesn't
work any more because it tries to access the seed pixel in all the
pieces, and thus it is out of their extents. In addition, the
algorithm won't work if applied in sub-samples.

How can I force the filter to be executed in a single node even if run
under mpi?
