Seymour Cray - Wikipedia, the free encyclopedia Cray was born in 1925 in Chippewa Falls, Wisconsin. Cray wanted to follow immediately, but William Norris refused as Cray was in the midst of completing a project for the US Navy, with whom Norris was interested in maintaining a good relationship. Cray always demanded an absolutely quiet work enviornment with a minimum of management overhead, but as the company grew he found himself constantly interrupted by middle-managers who (according to Cray) did little but gawk and use him as a sales tool by introducing him to prospective customers. en.wikipedia.org /wiki/Seymour_Cray   (1656 words)

Seymour Cray Obituary by John Markoff Cray, who as a young electrical engineer at the Control Data Corporation in the late 1950's led the design of the world's first transistor-based computer, went on to develop a string of supercompupting machines that were known for their elegance and simplicity, but most of all for their blazing speed. Cray is survived by two daughters, Susan Borman of Eau Claire, Wis., and Carolyn Arnold of Minneapolis; a, son, Steven, of Chippewa Falls, a sister, Carol Kersten of Rochester Minn., and five grandchildren. Cray was instrumental in creating a constant stream of design advances and innovative technologies that were later adopted by the rest of the computer industry. www.cs.wisc.edu /~bezenek/cray.html   (1821 words)

Cray-2 Encyclopedia Article, Definition, History, Biography Cray also felt that silicon technology had almost run its course; improvements on the Cray-1's 12.5 ns cycle time were possible, but much more than doubling didn't seem easy. Cray solved this by adding ten smaller computers to the system, allowing them to deal with the slower external storage (disks and tapes) and "squirt" data into memory when the main processor was busy. Cray had previously attacked the problem of increased speed with three simultaneous advances: more functional units to give the system higher parallelism, tighter packaging to decrease signal delays, and faster components to allow for a higher clock speed. encyclopedia.localcolorart.com /encyclopedia/Cray-2   (1682 words)

cray 1 Also unique was the Cray's use of low-density/very high-speed ECL circuits (that required liquid Freon for cooling in their cramped configuration), rather than high-density/slower speed devices. The Cray 1 was the world's first "supercomputer," a machine that leapfrogged existing technology when it was introduced in 1971. The sad part of the story is that Seymour Cray still had ideas he wanted to bring to reality at the time he was killed in a car accident. www.thocp.net /hardware/cray_1.htm   (704 words)

Seymour Cray's gone, but not forgotten Cray was born in Wisconsin in 1925 and served in the US army during World War II. Cray had contact with Von Neumann but with computing was in its infancy, many problems had not been explored and he had to rely on his own research and invention.

Seymour Cray Cray said he never heard of Boolean algebra while he was at the University, but whenever it was the he started using it he was truly in his natural element--mathematical and systems logic. Cray would have reason to be less optimistic today about that application of "number crunchers," as supercomputers are called, but he is pleasantly surprised at a new one. Cray was more than happy to turn over his managerial responsibilities to Rollwagen and others, though it caused something of a stir among stockholders who feared a rift. www.mbbnet.umn.edu /hoff/hoff_sc.html   (3275 words)

Wired News: SGI Set to Dump Cray? Cray Research was founded in 1972 by supercomputing legend Seymour Cray, to develop the world's fastest general purpose supercomputers. Another source said that Cray and Gores were hoping to make an announcement at last week's Supercomputing '99 conference in Portland, Oregon, which was a launching pad for a newly independent Cray, but the talks were still ongoing at the time of the show. At the time of the deal, Cray had about 4,500 employees, and about $900 million in revenues, but it was struggling to grow, amid declining US research and defense budgets, the biggest customers of the supercomputers Cray makes. www.wired.com /news/print/0,1294,32685,00.html   (966 words)

04/30/90 THE GENIUS Cray officially became a consultant to the company and devoted himself to the Cray-2, which then was intended to be the market's first GaAs computer. Seymour Cray is staking his reputation on the belief that GaAs technology has the same potential to vastly improve computer performance that silicon chips had 25 years ago. Cray does prefer econoboxes to fancy cars, though, and according to his sister, mounts a watch on the dashboard rather than ordering a clock. www.businessweek.com /1989-94/pre88/b31571.htm   (3519 words)

Wisconsin Academy Staff Development Initiative Initiated by Cray Research Co. in 1988, the Cray Academy has grown from serving about 200 teachers in its first year to over 700 in 1997.

Cray Supercomputer FAQ Cray machines could not support "alloca", so minor magic had to be applied to programs using "alloca." In the very early days, many C programs suffered from the "nUxi" problem, but that was hardly unique to Cray machines. On the company move to the "new" Cray Research Park from the 1440 Northland Drive facility, the first ducky day at the new location was celebrated by putting the torch to the wooden portion of the reassembled sculpture on the island in the middle of Cray Lake. Known collectively as the "Cray effect", they are the combination of algorithm scaling problems, cyclic accumulation of errors and parallelism interdependencies that seem to show up most times you take an apparently well behaved small program and run it longer harder and further than possible on a conventional system. www.faqs.org /faqs/computer/system/cray/faq   (7846 words)

Tribute to Seymour Cray When he started Cray Research in 1972, he shelved the 8600 design primarily because at that time he felt that the software issues were too great for the industry to handle and concluded that greater performance could be achieved in a uniprocessor by implementing vector capabilities. Once when told that Apple Computer bought a CRAY to simulate their next Apple computer design, Seymour remarked, "Funny, I am using an Apple to simulate the CRAY-3." His selection of people for his projects also reflected fundamentals. When he had to close the doors on Cray Computer Corporation in 1994, he immediately began to evaluate options available to build high performance systems out of commodity parts. www.cgl.ucsf.edu /home/tef/cray/tribute.html   (1266 words)

Cray forecasts Red Storm for masses CNET News.com A Cray representative pointed out that while the supercomputing industry has accepted 64-bit technology as its standard for a number of years, the ability to run some applications in 32-bit mode remains attractive to many users. Cray views Opteron as a perfect fit for both Red Storm and the company's upcoming product line because of the processor's ability to run both 32-bit and 64-bit software and its use of HyperTransport interface technology. Cray's announcement signifies increasing momentum in the supercomputer arena for AMD, which launched Opteron earlier this year in hopes of increasing its share of the corporate server market. news.com.com /2100-1008_3-5097398.html   (897 words)

ComputerUser.com News: Cray Inc. making a comeback The new Cray is the combination of Cray Research, founded by supercomputing pioneer Seymour Cray in 1972, and Seattle's Tera Computer Co., which was developing a new supercomputing system when the opportunity to buy the assets of Cray Research came up. Cray Inc., the company that invented the supercomputer, is engineering a comeback after faltering in the mid-1990s as linked servers poached its sales and a company that bought it killed off its product pipeline. Cray's business had been pressured by new technology that allowed computer makers to link servers together to achieve clusters of computers powerful enough to rival mainframes and supercomputers. www.computeruser.com /news/03/06/20/news8.html   (1152 words)

The Cray Y-MP C90 The machines from Cray Research Inc. are at this moment the only ones with a memory bandwidth as seems optimal for vector processors: two operands can be loaded and one result can be stored in one cycle for each pipe set. The C90 is the successor of the the Cray Y-MP and in many respects the machines are similar. For the C90 this meant that the relative bandwidth to the CPUs had to be doubled from 24 to 48 bytes/cycle. www.top500.org /reports/1994/Architec/node10.html   (289 words)
