pyMPI is a software project that integrates the Message Passing Interface (MPI) into the Python interpreter.

It allows one to write parallel programs using the Python language.

Example of usage[edit]

This python program:

$ mpirun -np 3 pyMPI
> import mpi
> print "Hi, I'm process #%d" % mpi.rank

will print this output:

Hi, I'm process #0
Hi, I'm process #1
Hi, I'm process #2

The -np parameter given to mpirun tells mpi to use 3 processes, and each process in its turn prints its output on the screen.
