Are there existing algorithms or solutions that make this easy to do? How do you split up the work and let the results from other machines come into effect?

Answer 1

Here's one simple way: generate a huge number of random (x,y) points where x and y are between 0 and 1. for each point, calculate whether its cartesian distance to the origin is <= 1 (that is, whether it lies on or inside the circle) count the number of point inside the circle versus outside the circle Pi, then, can be calculated from the ratio of inside to outside points. A very large number of points is necessary for this to approach pi, but if you have many machines, you can have each computer generate as many as you like, then simply return the counts to some leader machine, which would collect all the results and calculate the final ratio. This method can be used to calculate pi to any precision you want...the more points, the more precision. It's called a 'Monte Carlo' method because it uses randomness.
