Reply To: VTK Repeat Write


This looks very much as if you did not actually activate MPI in the config. mpirun doesn’t warn you if you try to call it with a non-mpi executable – it will just start the same programm n times without any work distribution. You probably also noticed that all terminal output is duplicated eight times?

If you change the config to use MPI (see the user guide or the example configs) and recompile, everything should work.
