Supertek
Supertek Computers Inc. was a computer company founded in Santa Clara, California in 1985 by Mike Fung, an ex-Hewlett-Packard project manager, with the aim of designing and selling low-cost minisupercomputers compatible with those from Cray Research. Its first product was the Supertek S-1, a compact, air-cooled, CMOS clone of the Cray X-MP vector processor supercomputer running the CTSS (Cray Time Sharing System) operating system, and later a version of Unix. This was launched in 1989; although Supertek had raised US$21.4 million in venture capital, only $5 million of this was needed to develop the S-1. Only ten units were sold before Supertek was acquired by Cray Research in 1990. The S-1 was subsequently sold for a brief time by Cray as the Cray XMS. At the time of the acquisition the Supertek S-2, a clone of the Cray Y-MP The Cray Y-MP was a supercomputer sold by Cray, Cray Research from 1988, and the successor to the company's Cray X-MP, X-MP. The Y-MP retained ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cray XMS
The Cray XMS was a vector processor minisupercomputer sold by Cray Research from 1990 to 1991. The XMS was originally designed by Supertek Computers Inc. as the Supertek S-1, intended to be a low-cost air-cooled clone of the Cray X-MP with a CMOS re-implementation of the X-MP processor architecture, and a VMEbus-based Input/Output Subsystem (IOS). The XMS could run Cray's UNICOS operating system. Supertek were acquired by Cray Research in 1990, and the S-1 was rebadged XMS by Cray. Its processor had a 55 ns clock period (18.2 MHz clock frequency) and 16 megawords (128 MB) of memory. The CRAY XMS system was the first CRI computer system to be supported by removable disk drives. Serial 5011, on display, was used for marketing purposes in the Eastern Region. It traveled for over 80,000 miles during its short working life and appeared at many trade shows. The XMS was a short-lived model, and was superseded by the Cray Y-MP EL, which was under development by Supertek (as the Su ...

Cray Research
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 became ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cray Time Sharing System
The Cray Time Sharing System, also known in the Cray user community as CTSS, was developed as an operating system for the Cray-1 or Cray X-MP line of supercomputers in 1978. CTSS was developed by the Los Alamos Scientific Laboratory (LASL now LANL) in conjunction with the Lawrence Livermore Laboratory (LLL now LLNL). CTSS was popular with Cray sites in the United States Department of Energy (DOE), but was used by several other Cray sites, such as the San Diego Supercomputing Center. Overview The predecessor of CTSS was the Livermore Time Sharing System (LTSS) which ran on Control Data CDC 7600 line of supercomputers. The first compiler was known as ''LRLTRAN'', for ''Lawrence Radiation Laboratory forTRAN'', a FORTRAN 66 programming language but with dynamic memory and other features. The Cray version, including automatic vectorization, was known as CVC, pronounced "Civic" like the Honda car of the period, for Cray Vector Compiler. Some controversy existed at LASL with the f ...

Cray Y-MP
The Cray Y-MP was a supercomputer sold by Cray, Cray Research from 1988, and the successor to the company's Cray X-MP, X-MP. The Y-MP retained software compatibility with the X-MP, but extended the address registers from 24 to 32 bits. High-density VLSI emitter-coupled logic, ECL technology was used and a new liquid-cooling system was devised. The Y-MP ran the Cray UNICOS operating system. The Y-MP could be equipped with two, four or eight vector processors, with two functional units each and a clock cycle time of 6 ns (167 MHz). Peak performance was thus 333 megaflops per processor. Main memory comprised 256, 512, or 1024 MB of static RAM, SRAM. (Memory was measured and allocated in 64 bit words, and offered in 32, 64, or 128 MWords). The original Y-MP (otherwise known as the Y-MP Model D) was housed in a chassis similar to the horseshoe-shaped X-MP, but with an extra rectangular cabinet added in the middle (containing the CPU boards), thus forming a "Y" shape in plan vie ...

Minisupercomputer
Minisupercomputers constituted a short-lived class of computers that emerged in the mid-1980s, characterized by the combination of vector processing and small-scale multiprocessing. As scientific computing using vector processors became more popular, the need for lower-cost systems that might be used at the departmental level instead of the corporate level created an opportunity for new computer vendors to enter the market. As a generalization, the price targets for these smaller computers were one-tenth of the larger supercomputers. Several notable technical, economic, and political attributes characterize minisupercomputers. First, they were architecturally more diverse than prior mainframes and minicomputers in hardware and less diverse in software. Second, advances in VLSI made them less expensive (mini-price). These machines were market targeted to be cost-effective and quickly manufactured. Third, it is notable who did not manufacture minisupercomputers: within the USA, IBM ...

Computer Companies Disestablished In 1990
A computer is a machine that can be programmed to automatically carry out sequences of arithmetic or logical operations (''computation''). Modern digital electronic computers can perform generic sets of operations known as ''programs'', which enable computers to perform a wide range of tasks. The term computer system may refer to a nominally complete computer that includes the hardware, operating system, software, and peripheral equipment needed and used for full operation; or to a group of computers that are linked and function together, such as a computer network or computer cluster. A broad range of Programmable logic controller, industrial and Consumer electronics, consumer products use computers as control systems, including simple special-purpose devices like microwave ovens and remote controls, and factory devices like industrial robots. Computers are at the core of general-purpose devices such as personal computers and mobile devices such as smartphones. Computers p ...
