Once upon a time, supercomputers used special vector model processors to achieve their then remarkable speeds. Then, at the turn of the 21st century, people began working out how to achieve record-breaking computer speed by linking hundreds or thousands of commercial microprocessors running Linux and connected with high-speed networking in MPP (massively parallel processor) arrays. [...]
