Parallel processing

Parallel processing is many problem solvers operating simultaneously or concurrently to reach a solution. A parallel processing computer system typically breaks down a big problem into many subproblems. It then solves it through close cooperation of a large number of interconnected processors. Parallel processing is the only way to overcome the limitation of traditional architectures. Following this direction, many new computer architectures have been proposed. They have opened up the possibility of constructing massively parallel computer systems that provide ultra high performance at reasonable costs
