Cray Inc., a subsidiary of Hewlett Packard Enterprise, is an American supercomputer manufacturer headquartered in Seattle, Washington. It also manufactures systems for data storage and analytics. Several Cray supercomputer systems are listed in the TOP500, which ranks the most powerful supercomputers in the world. In 1972, the company was founded by computer designer Seymour Cray as Cray Research, Inc., and it continues to manufacture parts in Chippewa Falls, Wisconsin, where Cray was born and raised. After being acquired by Silicon Graphics in 1996, the modern company was formed after being purchased in 2000 by Tera Computer Company, which adopted the name Cray Inc. In 2019, the company was acquired by Hewlett Packard Enterprise for $1.3 billion. History Background: 1950–1972 In 1950, Seymour Cray began working in the computing field when he joined Engineering Research Associates (ERA) in Saint Paul, Minnesota. There, he helped to create the ERA 1103. ERA eventually bec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subsidiary
A subsidiary, subsidiary company, or daughter company is a company (law), company completely or partially owned or controlled by another company, called the parent company or holding company, which has legal and financial control over the subsidiary company. Unlike regional branches or divisions, subsidiaries are considered to be distinct entities from their parent companies; they are required to follow the laws of where they are incorporated, and they maintain their own executive leadership. Two or more subsidiaries primarily controlled by same entity/group are considered to be sister companies of each other. Subsidiaries are a common feature of modern business, and most multinational corporations organize their operations via the creation and purchase of subsidiary companies. Examples of holding companies are Berkshire Hathaway, Jefferies Financial Group, The Walt Disney Company, Warner Bros. Discovery, and Citigroup, which have subsidiaries involved in many different Industry (e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Control Data Corporation
Control Data Corporation (CDC) was a mainframe and supercomputer company that in the 1960s was one of the nine major U.S. computer companies, which group included IBM, the Burroughs Corporation, and the Digital Equipment Corporation (DEC), the NCR Corporation (NCR), General Electric, Honeywell, RCA, and UNIVAC. For most of the 1960s, the strength of CDC was the work of the electrical engineer Seymour Cray who developed a series of fast computers, then considered the fastest computing machines in the world; in the 1970s, Cray left the Control Data Corporation and founded Cray Research (CRI) to design and make supercomputers. In 1988, after much financial loss, the Control Data Corporation began withdrawing from making computers and sold the affiliated companies of CDC; in 1992, CDC established Control Data Systems, Inc. The remaining affiliate companies of CDC currently do business as the software company Dayforce. Background: World War II – 1957 During World War II the Un ...

Gallium Arsenide
Gallium arsenide (GaAs) is a III-V direct band gap semiconductor with a Zincblende (crystal structure), zinc blende crystal structure. Gallium arsenide is used in the manufacture of devices such as microwave frequency integrated circuits, monolithic microwave integrated circuits, infrared light-emitting diodes, laser diodes, solar cells and optical windows. GaAs is often used as a substrate material for the epitaxial growth of other III-V semiconductors, including indium gallium arsenide, aluminum gallium arsenide and others. History Gallium arsenide was first synthesized and studied by Victor Goldschmidt in 1926 by passing arsenic vapors mixed with hydrogen over gallium(III) oxide at 600 °C. The semiconductor properties of GaAs and other Compound semiconductor, III-V compounds were patented by Heinrich Welker at Siemens-Schuckert in 1951 and described in a 1952 publication. Commercial production of its monocrystals commenced in 1954, and more studies followed in the 195 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cray-3
The Cray-3 was a Vector processor, vector supercomputer, Seymour Cray's designated successor to the Cray-2. The system was one of the first major applications of gallium arsenide (GaAs) semiconductors in computing, using hundreds of custom built integrated circuit, ICs packed into a central processing unit, CPU. The design goal was performance around 16 FLOPS, GFLOPS, about 12 times that of the Cray-2. Work started on the Cray-3 in 1988 at Cray, Cray Research's (CRI) development labs in Chippewa Falls, Wisconsin. Other teams at the lab were working on designs with similar performance. To focus the teams, the Cray-3 effort was moved to a new lab in Colorado Springs, Colorado later that year. Shortly thereafter, the corporate headquarters in Minneapolis decided to end work on the Cray-3 in favor of another design, the Cray C90. In 1989 the Cray-3 effort was spun off to a newly formed company, Seymour Cray#Cray Computer Corporation, Cray Computer Corporation (CCC). The launch cust ...

Cray X-MP
The Cray X-MP was a supercomputer designed, built and sold by Cray, Cray Research. It was announced in 1982 as the "cleaned up" successor to the 1975 Cray-1, and was the world's fastest computer from 1983 to 1985 with a quad-processor system performance of 800 MFLOPS. The principal designer was Steve Chen (computer engineer), Steve Chen. Description The X-MP's main improvement over the Cray-1 was that it was a shared-memory Parallel computing, parallel vector processor, the first such computer from Cray Research. It housed up to four CPUs in a mainframe that was nearly identical in outside appearance to the Cray-1. The X-MP CPU had a faster 9.5 nanosecond clock cycle (105 MHz), compared to 12.5 ns for the Cray-1A. It was built from Bipolar junction transistor, bipolar gate-array integrated circuits containing 16 emitter-coupled logic Logic gate, gates each. The CPU was very similar to the Cray-1 CPU in architecture, but had better memory bandwidth (with two read por ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cray-2
The Cray-2 is a supercomputer with four vector processors made by Cray Research starting in 1985. At 1.9 GFLOPS peak performance, it was the fastest machine in the world when it was released, replacing the Cray X-MP in that spot. It was, in turn, replaced in that spot by the Cray Y-MP in 1988. The Cray-2 was the first of Seymour Cray's designs to successfully use multiple CPUs. This had been attempted in the CDC 8600 in the early 1970s, but the emitter-coupled logic (ECL) transistors of the era were too difficult to package into a working machine. The Cray-2 addressed this through the use of ECL integrated circuits, packing them in a novel 3D wiring that greatly increased circuit density. The dense packaging and resulting heat loads were a major problem for the Cray-2. This was solved in a unique fashion by forcing the electrically inert Fluorinert liquid through the circuitry under pressure and then cooling it outside the processor box. The unique "waterfall" cooler s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
