Cray is a brand of Supercomputers with a 30 year history of innovation and leading edge performance. These computers are used to run demanding computational workloads and to solve massive calculations in science and engineering. Cray supercomputers provide superior sustained performance on critical applications, scalability to handle larger problems and the reliability to run jobs to completion. This gives scientists and engineers the ability to not only get answers faster but also allows a broad spectrum of users to ask new questions. Headquartered in Seattle, Washington, Cray employs approximately 800 people worldwide, with additional research and manufacturing facilities in Minnesota and Wisconsin, and sales and service locations around the world.

The range of Cray Superserver systems designated APP, SMP, CS6400 started with the acquisition of some of the assets of Floating point systems of Beaverton CO in 1991. These machines ran a modified version of SunMicrosystems Solaris OS providing a saleability well beyond that of any available Sun equipment. Using a system of domains, the machines, which could have up to 64 (60 MHz) Super SPARC, (later Ultra Sparc) CPUs, but could be reconfigured to appear as a group of smaller machines.
