[Paraview] MPI-aware reader plugin only has rank 0

[Biddiscombe, John A.]

When you said 

" rank/size: 0/4
However, all I ever get is the last line"

are you sure you don't mean that only printf/std:::cout from rank 0 is visible? but I actual fact the other pvservers are fine. Create a sphere and check if it has N pieces.

Thanks! This finally gives me hope that not everything is completely broken, as it yields the expected output (for 5 ranks):

rank 0
total 5
rank 2
total 5
rank 1
total 5
rank 4
total 5
rank 3
total 5

No change on the reader plugin though. Are there certain commands/libraries I have to include in the CMakeLists.txt file to make the plugin run in parallel? Or additional (VTK) methods I have to call to make sure that all ranks are participating?
