Parallel computing can be done in many ways including:

• using multiple processus, based on fork(). This will yield different result on Windows because Windows do not have fork() system call. I would recommand not using this if you want compatibility on Windows.
• using multiple threads.

Most python libraries for parallel computing provides a way to use a pool of work in order to map a given list x with a function f. The computation of all the f(x[i]) will be automatically scheduled on the pool of worker (and done in parallel if possible).

Here is two simple ways to use this map methods.
