SignifFour years afterwards abrogation CDC, Cray delivered the 80 MHz Cray 1 in 1976, and it become one of the best acknowledged supercomputers in history.89 The Cray 1 was a agent processor which alien a cardinal of innovations such as chaining in which scalar and agent registers accomplish acting after-effects which can be acclimated immediately, after added anamnesis references which abate computational speed.10 The Cray X-MP (designed by Steve Chen) was appear in 1982 as a 105 MHz shared-memory alongside agent processor with more good chaining abutment and assorted anamnesis pipelines. All three amphibian point pipelines on the XMP could accomplish simultaneously.10
The Cray-2 appear in 1985 was an 8 processor aqueous cooled computer and Fluorinert was pumped through it as it operated. It performed at 1.9 gigaflops and was the world's fastest until 1990 back ETA-10G from CDC overtook it. The Cray 2 was a absolutely fresh architecture and did not use chaining and had a aerial anamnesis latency, but acclimated abundant abysmal pipelining and was ideal for problems that appropriate ample amounts of memory.10 Thecomputer application costs in developing a supercomputer should not be underestimated, as apparent by the actuality that in the 1980s the amount forcomputer application development at Cray came to according what the spent on hardware.11 That trend was partly amenable for a move abroad from the in-house, Cray Operating System to UNICOS based on Unix.11
The Cray Y-MP, additionally advised by Steve Chen, was appear in 1988 as an advance of the XMP and could accept eight agent processors at 167 MHz with a aiguille achievement of 333 megaflops per processor.10 In the backward 1980s, Cray's agreement on the use of gallium arsenide semiconductors in the Cray-3 did not succeed. Cray began to assignment on a massively alongside computer in the aboriginal 1990s, but died in a car blow in 1996 afore it could be completed.9enchmark in 1996; eventually extensive 2 teraflops.21
