[Paraview] parallel run filter operate on plane source

[Bam Ting]

Forgive my misconception before! I am baffelt by how this work!

I looked closer. I see plane source on my imput is empty! bounds 1 -1 ...
on all process except 0... so that answer something! before this I suppose
that the source must be duplicate on all process, because the class doc for
vtkPStreamTracer say thaat this must be so. Now I will like to know how does
filter such as distributed stream tracer work in this case (plane source is
empty on all imput except 0)? Web doc day seed points must be the same
across on all process? Can we explain how paraview works here?
