Cray Room

This room contains several computers and objects associated with Cray Research, Inc.

Founded in 1972 by the legendary former Control Data Corporation employee and “Father of Supercomputing” Seymour Cray, Cray Inc. was almost synonymous with the supercomputer for decades.

Cray-1

Announced in 1975, the first Cray-1 system was installed at Los Alamos National Laboratory in 1976. 80 were sold in total, making this C-shaped supercomputer one of the most successful in history.

Cray Q2 Prototype

This rare prototype supercomputer represents an intermediate stage in the design process between the Cray 1 and Cray 2

This new system generated so much heat that the previous method of air-cooling the computer was no longer sufficient. This new design was instead cooled by immersion in 200 gallons of a supercooled and inert liquid calledfluorinert.

Cray T94

The Cray T94, which shipped in 1995, was the last of the vector processing supercomputers.

Liquid cooled, thousands of pounds, and using over 70 kilowatts of electricity, the Cray T94 was used to discover a new prime number with over 378,000 digits and has significantly less processing power than a modern laptop.
