 where ''-n 4'' specifies the number of processes to be run in parallel to be four. Now if everything worked correctly you should have already felt an increase in performance -- i.e. the program should have terminated its computation more quickly. where ''-n 4'' specifies the number of processes to be run in parallel to be four.

 +To use multiple machines as a cluster the specifics might be different depending on the MPI implementation used. For OpenMPI it suffices, if the same home directory is mounted on all machines, to add a hostfile containing the names of all machines in the luster to the command line (e.g. ''mpirun -n 32 -f hostfile.mpi ./sim_background''). However, since for MPICH2 and other implementations the workflow is slightly different, I would recommend the user to look at the respective tutorials corresponding to their local MPI flavor.
