A high-performance computer is
|“||[a]t any given time, that class of general-purpose computers that are both faster than their commercial competitors and have sufficient central memory to store the problem sets for which they are designed. Computer memory, throughput, computational rates, and other related computer capabilities contribute to performance. In addition, performance is often dependent on details of algorithms and on data throughput requirements. Consequently, a quantitative measure of computer power in large-scale scientific processing is difficult to formulate and may change as the technology progresses.||”|
