parallel computing in python script

I am using a Monte Carlo simulation. Due to this simulation, it is taking a lot of time (approximately 40 hours). Can I use parallel computing in my script? If yes, then how?

Why don't you use directly the Monte Carlo functionality within FePEST application? You can parallelize with a couple of clicks only.. Cheers Carlos

Thank you for your reply. Actually, i used Monte Carlo simulation to produce Stage hydrographs, which i have to import in fem model. Which is time consuming. is there any way by which i can reduce computation time?
