Dear Berk, I tried your suggestion and coloured the result with the ProcessIdScalars Filter. I can see the partitioning and it also makes sense, so there should not be any major load imbalance. I did add some timing information in the code. I add the changed program. It is evident that the data in

Hi Olaf, >From your previous message, I am assuming that you are using vtr files. In this case, the processing should scale. If you can make an example files available, I can verify this. Feel free to e-mail them to me directly or I can download them somewhere if they are too big. The two potentia

Dear Paraview developers and users, I tried to run paraview in parallel using a python script. I compiled a server including OpenMPI support and support for MESA off-screen rendering and started the server using mpirun. The I connected from a python script (see attachment). I could see that there
