Seymour Roger Cray (September 28, 1925 – October 5, 1996) was an American electrical engineer and supercomputer architect who designed a series of computers that were the fastest in the world for decades, and founded Cray Research which built many of these machines. Called "the father of supercomputing", Cray has been credited with creating the supercomputer industry.

History. From 1968 to 1972, Seymour Cray of Control Data Corporation (CDC) worked on the CDC 8600, the successor to his earlier CDC 6600 and CDC 7600 designs. The 8600 was essentially made up of four 7600s in a box with an additional special mode that allowed them to operate lock-step in a SIMD fashion.. Jim Thornton, formerly Cray's engineering partner on …

Seymour Cray sperrte sich lange Zeit gegen die Einführung von Multiprozessor-Fähigkeiten; seiner Meinung nach war eine einzelne, dafür aber sehr schnelle CPU mehreren langsameren CPUs überlegen.Begrenzte Multiprozessorfähigkeiten wurden erst mit dem Nachfolger der Cray-1 eingeführt, der Cray X-MP, die bis zu vier CPUs unterstützte.. 1993 wurde der erste massiv …

Las supercomputadoras fueron introducidas en la década de 1970 y fueron diseñadas principalmente por Seymour Cray en la compañía Control Data Corporation (CDC), la cual dominó el mercado durante esa época, hasta que Cray dejó CDC para formar su propia empresa, Cray Research.Con esta nueva empresa siguió dominando el mercado con sus nuevos …

Seymour Cray famously said "parity is for farmers" when asked why he left this out of the CDC 6600. Later, he included parity in the CDC 7600, which caused pundits to remark that "apparently a lot of farmers buy computers".The original IBM PC and all PCs until the early 1990s used parity checking. Later ones mostly did not. An ECC-capable memory controller can generally detect …

Seymour Cray began to work on a massively parallel computer in the early 1990s, but died in a car accident in 1996 before it could be completed. Cray Research did, however, produce such computers. Massive processing: the 1990s. The Cray-2 which set the frontiers of supercomputing in the mid to late 1980s had only 8 processors. In the 1990s ...

This article documents the progress of significant human–computer chess matches.. Chess computers were first able to beat strong chess players in the late 1980s. Their most famous success was the victory of Deep Blue over then World Chess Champion Garry Kasparov in 1997, but there was some controversy over whether the match conditions favored the computer.

Un supercalculateur Cray-2, inventé par Seymour Cray et lancé à partir de 1985. C’est seulement vers la fin des années 1980 que la technique des systèmes massivement parallèles est adoptée, avec l’utilisation dans un même superordinateur de milliers de processeurs.

CDC's first products were based on the machines designed at ERA, which Seymour Cray had been asked to update after moving to CDC. After an experimental machine known as the Little Character, in 1960 they delivered the CDC 1604, one of the first commercial transistor-based computers, and one of the fastest machines on the market.Management was delighted, and …

As of 2011, practical computer vision applications require 10,000 to 1,000,000 MIPS. By comparison, the fastest supercomputer in 1976, Cray-1 (retailing at $5 million to $8 million), was only capable of around 80 to 130 MIPS, and a typical desktop computer at the time achieved less than 1 MIPS. Intractability and the combinatorial explosion.
