It's mainly used for programs that needs lots of processing power chucked at a specific problem, the problem is first broken down into several small pieces and each part is sent off to a different processor. When each piece has been processed, they are all recombined and the rest of the calculation is continued. The problem with this is that if any one of the pieces is delayed, all the processors will be idle waiting for the interrupted piece to be processed, before they can process the next set of pieces.
