the command mpirun…
Thanks!
#!/usr/bin/env python
"""
Parallel Hello World

from mpi4py import MPI
import sys
size = MPI.COMM_WORLD.Get_size()
rank = MPI.COMM_WORLD.Get_rank()
name = MPI.Get_processor_name()
sys.stdout.write(
"Hello, World! I am process %d of %d on %s.\n"
% (rank, size, name))
~/bin/mpirun -np 70 python2.7 helloworld.py
