This worksheet calculates the value of Pi via a multi-threaded (and a single-threaded) Monte-Carlo algorithm. Ntotal darts are randomly thrown at a unit square inscribed with a circle, and the number N that land within the circle are counted. The value of Pi is 4N/N_total.

The fractional speed-up of the multi-threaded version over the single-threaded version is calculated. Typically on a dual core computer, the speedup is about 30%.

This application was created in Maple 13.02, and uses features that may not be available with earlier versions of Maple.
