Judging by your screenshot the “case you ran before in 1.5” is the same channel3d you are running now?

Please describe exactly what you are doing. As I mentioned the 8-fold duplication of VTK output points strongly towards you still using mpirun -np 8 for a non-MPI executable. You likely also have a contaminated tmp folder and build (which is why I suggested to fully clear the directory).

The line of code you posted will do exactly what its comment describes. Again, the duplicated lines you see are due to not compiling the application with MPI enabled but trying to run it using mpirun.
