PyMPI
From Wikipedia, the free encyclopedia
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.
[edit] Example of usage
If you run this python program:
$ mpirun -np 3 pyMPI > import mpi > print "Hi, I'm process #%d" % mpi.rank
It 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 it's output on the screen.
