When I first read about processes in Erlang and how to program for concurrency within the language, I decided to write a simple parallel implementation of the well-known Quicksort algorithm as an exercise. The reason I chose this algorithm in particular is because it is, by nature, easily parallelizable. If it's been a while since you last implemented Quicksort, here's a short overview of what the algorithm does:

1. The function receives a list of elements
2. A pivot is chosen from this list (Usually the first element)
3. The original list is separated into two new lists: One that contains all elements that are less than the pivot and one that contains all elements that are greater than the pivot
4. The two new lists are sorted separately
5. The sorted lists are joined by placing the pivot between them
