First ever Cray T3D supercomputer goes to auction with $81,000 reserve

The first Cray T3D ever produced has gone up for auction, giving collectors and computing museums a rare chance to buy a historically important supercomputer. The machine carries serial number 6001 and is listed with opening bids from £60,000, or about $81,000.

This particular Cray T3D has a strong history. It was first used as Cray’s internal development machine before being installed at Edinburgh University, where it became known as Typhoon. In June 1996, the TOP500 list ranked Typhoon as the fastest supercomputer in Europe, making it much more than an old piece of hardware.

The Cray T3D marked a major shift toward massively parallel supercomputing

The T3D was important because it represented Cray’s move away from relying mainly on traditional vector supercomputing and toward massively parallel systems. That change helped shape the direction of high performance computing, where large numbers of processors work together to solve complex problems.

The auction listing describes the machine as a museum grade survivor, and that description fits. This is not the kind of computer someone can easily place in a home office or garage. The main cabinet is more than 6 feet tall, finished in Cray’s bright Tomato Red color, and measures around 193 cm high, 117 cm wide, and 193 cm deep.

Inside the single cabinet Cray T3D MC512 are 512 DEC Alpha 21064 processors running at 150MHz. The system uses Fluorinert liquid based cooling, and the auction also includes the HEU first stage cooling system. That cooling unit is also more than 6 feet tall and weighs around 0.85 tons.

The price is high, but the machine originally cost around $15 million when new. Even so, the auction may have a limited audience. The size, weight, transport cost, power needs, and maintenance demands make it difficult for normal collectors. At the time of the report, the listing had no bids and only 10 watchers, with the auction scheduled to end on May 31.

Two other Cray systems are also being auctioned at the same time: a Cray Triton T 932 and a Cray Y MP4E. That makes the sale notable for anyone interested in the history of supercomputing, not just this one machine.

The Cray T3D may no longer be useful for modern computing work, but its value is historical. It comes from a period when supercomputers were moving into a new era, and Cray was trying to adapt its legendary status to massively parallel designs.

For the right buyer, Typhoon is less like buying a computer and more like buying a piece of computing history. It is large, expensive, difficult to move, and probably impossible to justify as practical hardware today. But as the first Cray T3D and a former European performance leader, it is a rare artifact from one of the most important periods in supercomputer development.
