CMPSC 450 definitions CMPSC 450 What is a ‘parallel computer’? • A parallel computer consists of a number of tightly-coupled compute elements that cooperatively solve a problem. • Example of `tight coupling’: shared caches, shared main memory, shared led system, high-speed access to data, high-speed network connecting compute nodes. • Cooperatively solving implies manual or
