CRAY 3 SUPERCOMPUTER.
complete processing "octant," early 1990s, consisting of a 10-module processor "brick" and a 32-module memory "brick," each with brass bus bars at base for mounting to power bars in Fluorinert-filled cooling tank; the other a "brick" of 10 modules. Both with attached looms of two-conductor blue and white wires fitted with plastic connectors. The larger block mounted to a later wooden base. Size approximately 335 x 200 x 200 mm (excluding base), and 250 x 120 x 170 mm.
The Cray 3 was the first offering of the Cray Computer Corporation, Seymour Cray's spin-off from Cray Research, Inc., the company that he created in 1972 after he left Control Data Corporation. The Cray 3 was the first supercomputer to use gallium arsenide integrated circuits for all of its logic circuitry and was the fastest computer of its time. The changing political climate at the end of the cold war drastically shrank the supercomputer market and much of the market turned to massively parallel designs. Cray ended up loaning a Cray 3 to the National Center for Atmospheric Research (NCAR) and another government order the company received was cancelled.
From the original Cray 3 brochure: "The Cray-3 logic and memory circuitry is packaged in up to 336 removable modules, each containing up to 1,024 GaAs integrated circuit die. Total integrated circuit population in a 16-processor Cray-3 is over 142,000 die, of which 36,864 are for common memory. The packaging results in a GaAs gate density of approximately 96,000 gates per cubic inch. The modules are three-dimensional structures measuring 121 mm by 107 mm by 7 mm. Nine printed circuit boards make up the [core of the] module sandwich and contain a total of 69 electrical layers. Circuit connections are made in all three dimensions within the module. X-y traces are as small as 0.048 mm. Z-axis connections are made with approximately 14,000 gold-plates, beryllium-copper twist-pin jumpers per module. The logic signal jumpers, which make up the bulk of the z-axis connections, are only 0.122 mm in diameter."
The two bricks together represent the smallest Cray 3 module compliment that a customer could purchase and is likely the only complete one in existence. It comes from an employee of Cray Computer Corporation.
