A supercomputer is a computer with considerably higher compute, memory, storage, and network capabilities than a typical mainstream computer.

Overview

A supercomputer is a computer with typically much higher compute capabilities than comprable mainstream computers. It is often built in order to solve challenging problems in science and engineering.

Though historically (1970s-1990s), supercomputers were built from individual, custom CPUs, modern systems comprise a number of individual standardized commercial systems interconnected to form a large complex system through one of the well-known interconnects architectures such as InfiniBand, Ethernet, and Omni-Path.
