[Paraview] Find Data does not work on MPI

[Magician]

Hi Mathieu,


Thanks for your advice.

I searched the mpirun/mpiexec on my /ParaView folder, but no executable is found.
PV 4.4.0 (provided by Kitware) has mpirun/mpiexec in the /bin folder, but the latest version doesn’t.

Are there additional install options?
