CRAY 2: ORIGINAL MODULES & COMPONENTS.2 8-layer modules, one logic, the other memory, each 228 x 105 mm, Cray Research, 1985, WITH: Cray 2 capacitor bay, 255 x 104 mm, with Lucite stand.
AND WITH: Cray 2 power module, 246 x 105 mm, with lucite stand.
Seymour Cray joined Engineering Research Associates (ERA) in 1951 after graduating from the University of Minnesota with a B.Sc. in Electrical Engineering and a M.Sc. in applied mathematics. He quickly became respected among the engineers and was assigned the difficult task of designing a control system for the EA 1103, which went on to become the first commercially successful scientific computer.
Cray became dissatisfied with ERA after they had been bought first by Remington Rand and then by the Sperry Corporation. He, along with William Norris, one of ERA's founders, left to form Control Data Corporation (CDC). There he was responsible for the design of the CDC 1604, initial work on the 3000 series, the CDC 6600—generally considered to be the first successful supercomputer—and the CDC 7600.
In 1972 Cray left CDC to form Cray Research with a sizeable investment from CDC. At Cray Research he designed a supercomputer 5 times faster than the CDC 7600. The Cray 1 was the first supercomputer to successfully implement the vector processor design and was one of the most successful supercomputers in history, selling over 100 units at a cost of almost $8 million.
The Cray 2 was his follow up created in his new Cray Lab in Boulder Colorado by his personally-assembled team, away from the management interruptions at Cray Research headquarters in Chippewa Falls, Wisconsin. Here Cray, as in the past, was able to double the clock speed of his previous machine through increased density of the smaller ICs available at the time. Cray also separated the memory into quadrants that could be accessed simultaneously, allowing for higher parallelism.
The other major innovation was Cray's ingenious idea to achieve the necessary density by stacking the circuit boards closely together connected by pins sticking up from the surface. A stack of 8 boards, such as the two examples in the present lot, would only be a couple of inches high. This necessitated a new cooling method since air would not be able to flow between the layers so a new inert liquid manufactured by 3M, Fluorinert was used. Cray would also use the same cooling method in his follow-up, the Cray 3.
The Cray 2 was finally released in 1985 and at 1.9 GFLOPS peak performance, was the fastest computer in the world.
