In that case, you have three options:

* Write separate Python programs that communicate with each other over
sockets, CORBA, or some other IPC mechanism

* Use or write a Python extension and make your program threaded (NumPy
may be of help if it releases the GIL)

* Forget about getting a performance boost out of SMP
