Hi Manuel,
You should get an error message indicating that you need to provide the device list as arguments but that output seems to have disappeared.
So, you should run it as e.g. :
mpirun -np 6 mpi_test 0 1 2 3 4 5
The segmentation fault when no argument is provided is a bug though. I will fix it.

Bug should be fixed.

Oh! I missed that you have arguments when calling the program. Thx for the fix!
