Cray purchased Supertek in and sold the S-1 as the Cray XMSbut the machine proved problematic; meanwhile, their not-yet-completed S-2, a Y-MP clone, was later offered as the Cray Y-MP EL later becoming the EL90 series which started to sell in reasonable numbers in β€”92β€”to mostly smaller companies, notably in the oil exploration business.

Facing these threats, Rollwagen reportedly realized in that he had put the wrong man in charge in the person of Gumucio. As the s began, the company decided to begin development of the next generation of supercomputers.

But when Cray approached Wall Street to look for seed capital, he was surprised to find that his reputation was very well known.

Cray-1

Integer and floating point arithmetic was supported. SGI the following year in Cray Research also took measures to provide for better distribution of its products. Seymour was rushed to the hospital but died there three days later. But perhaps the amount of scientific knowledge that was generated thanks to the raw computational power Seymour gave the world was bequest enough, and then some. Red Storm also included an innovative new design for network interconnects, which was dubbed SeaStar and destined to be the centerpiece of succeeding innovations by Cray. January 15, Somewhere in the recesses of my memory there lives a small photograph, from one of the many magazines that fed my young interests in science and electronics β€” it was probably Popular Science. Cray Research underwent a major restructuring in By he had completed the design of the CDC , an improved low-cost version of ERA , that had impressive performance for its price range. In , Cray opened a subsidiary in China.

In addition, there were plans to bring to the market an entry-level supercomputer, which would use the technology of the CRAY Y-MP, but would have a much lower price with reduced installation and operating costs.

His father, a civil engineer, encouraged his obvious early interest in the technical world, with radio playing a central role in his interests.

The Convex Computer series, as well as a number of small-scale parallel machines from companies like Pyramid Technology and Alliant Computer Systems were particularly popular. The clock signal is distributed via a fiber optic harness to the processors.

It shared the classic "C" or "Horseshoe" design of the earlier Cray-1 machine and looked almost identical on the outside. It was sexy as hell, and became the must-have machine for big number-crunchers. Operator input was via a keyboard. Cray retained his ties with the company as an independent contractor and as a member of the board of directors. Cascade was scheduled to be introduced in early and designed to use the next-generation network chip and follow-on to Gemini, code named Aries. Red Storm had processors clustered in 96 unit cabinets, a theoretical maximum of cabinets in a machine, and a design speed of Back to Chippewa Falls With the sale of ERA to Remington Rand and a concentration on machines and processes specifically for business, Seymour saw the writing on the wall. He was 71 years old. The company's first product, the Cray-1 supercomputer, was a major success because it was significantly faster than all other computers at the time. Seymour Cray continued working, this time on the Cray-2 , though it only ended up being marginally faster than the Cray X-MP , developed by another team at the company. It had a distributed architecture central scientific processor supported by ten very fast peripheral machines and was a reduced instruction set RISC machine many years before such a term was invented.

With newer, faster silicon transistors, the CDCan order of magnitude faster than any other machine on the market, debuted in Most sites with a Cray installation were considered a member of the "exclusive club" of Cray operators.

The main register set consisted of eight bit scalar S registers and eight bit address A registers, backed by a set of sixty-four registers each for S and A temporary storage known as T and B respectively, which could not be seen by the functional units.

During its early years of operation, Cray Research sold its supercomputers to government laboratories and agencies. Measures 4 inches high x 3 inches wide, 1" thick. Among the victims was Cray Computer, which declared bankruptcy early in This sale enabled it to earn back its original investment. Facing these threats, Rollwagen reportedly realized in that he had put the wrong man in charge in the person of Gumucio. In , Cray announced the Cray XK6 hybrid supercomputer. Seymour Cray continued working, this time on the Cray-2 , though it only ended up being marginally faster than the Cray X-MP , developed by another team at the company.

Seymour Cray resigned from the board of directors of Cray Research, severing formal connections with the company he had formed, although he remained a stockholder. Even without having filled the backlogged orders, Cray could still boast of having increased its installed base to systems in 37 countries nearly three times the level of
