Supercomputers are extremely fast computers that help us to understand the world around us, allowing us to stay healthy and safe while looking after our planet.  EPCC at the University of Edinburgh runs the ARCHER service, the UK’s primary academic research supercomputer. Learn more.

What is a supercomputer?

A supercomputer is an extremely fast computer, usually millions of times faster than a normal home computer. Typically created by coupling together a very large number of normal computers, their overall capacity to crunch numbers is very high.

Why are supercomputers important?

Supercomputers allow us to understand things that are too difficult to see or measure in real life. Examples include weather forecasts, creating new medicines and reducing pollution from planes, boats and cars.

How do you use a supercomputer?

Supercomputer programs are developed in a similar way to programs for a desk top computer. Additional options are needed to describe how you share information and send messages between the coupled computers.
