Seymour Roger Cray 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. Joel S. Birnbaum, then chief technology officer of Hewlett-Packard, said of him: "It seems impossible to exaggerate the effect he had on the industry; many of the things that high performance computers now do routinely were at the farthest edge of credibility when Seymour envisioned them." Larry Smarr, then director of the National Center for Supercomputing Applications at the University of Illinois said that Cray is "the Thomas Edison of the supercomputing industry."
The Cray-1 was a supercomputer designed, manufactured and marketed by Cray Research. Announced in 1975, the first Cray-1 system was installed at Los Alamos National Laboratory in 1976. Eventually, eighty Cray-1s were sold, making it one of the most successful supercomputers in history. It is perhaps best known for its unique shape, a relatively small C-shaped cabinet with a ring of benches around the outside covering the power supplies and the cooling system.
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, and 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, Cray established Control Data Systems, Inc. The remaining affiliate companies of CDC currently do business as the software company Ceridian.
Thinking Machines Corporation was a supercomputer manufacturer and artificial intelligence (AI) company, founded in Waltham, Massachusetts, in 1983 by Sheryl Handler and W. Daniel "Danny" Hillis to turn Hillis's doctoral work at the Massachusetts Institute of Technology (MIT) on massively parallel computing architectures into a commercial product named the Connection Machine. The company moved in 1984 from Waltham to Kendall Square in Cambridge, Massachusetts, close to the MIT AI Lab. Thinking Machines made some of the most powerful supercomputers of the time, and by 1993 the four fastest computers in the world were Connection Machines. The firm filed for bankruptcy in 1994; its hardware and parallel computing software divisions were acquired in time by Sun Microsystems.
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.
The Cray X-MP was a supercomputer designed, built and sold by 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.
Alliant Computer Systems Corporation was a computer company that designed and manufactured parallel computing systems. Together with Pyramid Technology and Sequent Computer Systems, Alliant's machines pioneered the symmetric multiprocessing market. One of the more successful companies in the group, over 650 Alliant systems were produced over their lifetime. The company was hit by a series of financial problems and went bankrupt in 1992.
The Cray Y-MP was a supercomputer sold by Cray Research from 1988, and the successor to the company's 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 ECL technology was used and a new liquid-cooling system was devised. The Y-MP ran the Cray UNICOS operating system.
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.
Floating Point Systems, Inc. (FPS), was a Beaverton, Oregon vendor of attached array processors and minisupercomputers. The company was founded in 1970 by former Tektronix engineer Norm Winningstad, with partners Tom Prince, Frank Bouton and Robert Carter. Carter was a salesman for Data General Corp. who persuaded Bouton and Prince to leave Tektronix to start the new company. Winningstad was the fourth partner.
The Cray-3 was a 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 ICs packed into a 1 cubic foot (0.028 m3) CPU. The design goal was performance around 16 GFLOPS, about 12 times that of the Cray-2.
Steve Chen is a Taiwanese computer engineer and internet entrepreneur.
MasPar Computer Corporation was a minisupercomputer vendor that was founded in 1987 by Jeff Kalb. The company was based in Sunnyvale, California.
The Cray J90 series was an air-cooled vector processor supercomputer first sold by Cray Research in 1994. The J90 evolved from the Cray Y-MP EL minisupercomputer, and is compatible with Y-MP software, running the same UNICOS operating system. The J90 supported up to 32 CMOS processors with a 10 ns clock. It supported up to 4 GB of main memory and up to 48 GB/s of memory bandwidth, giving it considerably less performance than the contemporary Cray T90, but making it a strong competitor to other technical computers in its price range. All input/output in a J90 system was handled by an IOS called IOS Model V. The IOS-V was based on the VME64 bus and SPARC I/O processors (IOPs) running the VxWorks RTOS. The IOS was programmed to emulate the IOS Model E, used in the larger Cray Y-MP systems, in order to minimize changes in the UNICOS operating system. By using standard VME boards, a wide variety of commodity peripherals could be used.
The Cray EL90 series was an air-cooled vector processor supercomputer first sold by Cray Research in 1993. The EL90 series evolved from the Cray Y-MP EL minisupercomputer, and is compatible with Y-MP software, running the same UNICOS operating system. The range comprised three models:
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 and 16 megawords of memory.
The Cray S-MP was a multiprocessor server computer sold by Cray Research from 1992 to 1993. It was based on the Sun SPARC microprocessor architecture and could be configured with up to eight 66 MHz BIT B5000 processors. Optionally, a Cray APP matrix co-processor cluster could be added to an S-MP system.
The Cray APP was a parallel computer sold by Cray Research from 1992 onwards. It was based on the Intel i860 microprocessor and could be configured with up to 84 processors. The design was based on "computational nodes" of 12 processors interconnected by a shared bus, with multiple nodes connected to each other, memory and I/O nodes via an 8×8 crossbar switch.
Celerity Computing, Inc., was a publicly traded vendor of Unix-based minisupercomputers based in San Diego, California. Celerity Computing was founded in May 1983 by Steve Vallender, Nick Aneshansley and Andrew McCroklin. All were former employees of NCR Corporation.
The history of supercomputing goes back to the 1960s when a series of computers at Control Data Corporation (CDC) were designed by Seymour Cray to use innovative designs and parallelism to achieve superior computational peak performance. The CDC 6600, released in 1964, is generally considered the first supercomputer. However, some earlier computers were considered supercomputers for their day such as the 1954 IBM NORC in the 1950s, and in the early 1960s, the UNIVAC LARC (1960), the IBM 7030 Stretch (1962), and the Manchester Atlas (1962), all of which were of comparable power.
