Edinburgh Concurrent Supercomputer Project
The Edinburgh Concurrent Supercomputer (ECS) was a large Meiko Computing Surface supercomputer. This transputer-based, massively parallel system was installed at the University of Edinburgh during the late 1980s and early 1990s. History Following a pilot project involving an early 40-transputer Computing Surface installed in April 1986, funding was obtained from SERC and the DTI for a much larger system using T800 transputers and a MicroVAX fileserver. The Edinburgh Concurrent Supercomputer Project (ECSP) was formed to manage and support the facility, which was commissioned at the end of 1987. Over the next few years, the system received several upgrades, including more transputers (reaching, at its peak, around 400 processors) and the installation of M²VCS and MeikOS system software, which enabled multi-user access and removed the need for the MicroVAX. In 1990, the Edinburgh Concurrent Supercomputer Project was succeeded by the Edinburgh Parallel Computing Centre, which c ...

Meiko Computing Surface
Meiko Scientific Ltd. was a British supercomputer company based in Bristol, founded by members of the design team working on the Inmos transputer microprocessor. History In 1985, when Inmos management suggested the release of the transputer be delayed, Miles Chesney, David Alden, Eric Barton, Roy Bottomley, James Cownie, and Gerry Talbot resigned and formed Meiko (Japanese for "well-engineered") to start work on massively parallel machines based on the processor. Nine weeks later in July 1985, they demonstrated a transputer system based on experimental 16-bit transputers at the SIGGRAPH in San Francisco. In 1986, a system based on 32-bit T414 transputers was launched as the ''Meiko Computing Surface''. By 1990, Meiko had sold more than 300 systems and grown to 125 employees. In 1993, Meiko launched the second-generation ''Meiko CS-2'' system, but Meiko ran into financial difficulties in the mid-1990s. The Meiko technical team and technology was transferred to a joint venture co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Supercomputer
A supercomputer is a computer with a high level of performance as compared to a general-purpose computer. The performance of a supercomputer is commonly measured in floating-point operations per second ( FLOPS) instead of million instructions per second (MIPS). Since 2017, there have existed supercomputers which can perform over 1017 FLOPS (a hundred quadrillion FLOPS, 100 petaFLOPS or 100 PFLOPS). For comparison, a desktop computer has performance in the range of hundreds of gigaFLOPS (1011) to tens of teraFLOPS (1013). Since November 2017, all of the world's fastest 500 supercomputers run on Linux-based operating systems. Additional research is being conducted in the United States, the European Union, Taiwan, Japan, and China to build faster, more powerful and technologically superior exascale supercomputers. Supercomputers play an important role in the field of computational science, and are used for a wide range of computationally intensive tasks in var ...

Transputer
The transputer is a series of pioneering microprocessors from the 1980s, intended for parallel computing. To support this, each transputer had its own integrated memory and serial communication links to exchange data with other transputers. They were designed and produced by Inmos, a semiconductor company based in Bristol, United Kingdom. For some time in the late 1980s, many considered the transputer to be the next great design for the future of computing. While the transputer did not achieve this expectation, the transputer architecture was highly influential in provoking new ideas in computer architecture, several of which have re-emerged in different forms in modern systems. Background In the early 1980s, conventional central processing units (CPUs) appeared to have reached a performance limit. Up to that time, manufacturing difficulties limited the amount of circuitry that could fit on a chip. Continued improvements in the fabrication process had largely removed this ...

Massively Parallel
Massively parallel is the term for using a large number of computer processors (or separate computers) to simultaneously perform a set of coordinated computations in parallel. GPUs are massively parallel architecture with tens of thousands of threads. One approach is grid computing, where the processing power of many computers in distributed, diverse administrative domains is opportunistically used whenever a computer is available.''Grid computing: experiment management, tool integration, and scientific workflows'' by Radu Prodan, Thomas Fahringer 2007 pages 1–4 An example is BOINC, a volunteer-based, opportunistic grid system, whereby the grid provides power only on a best effort basis.''Parallel and Distributed Computational Intelligence'' by Francisco Fernández de Vega 2010 pages 65–68 Another approach is grouping many processors in close proximity to each other, as in a computer cluster. In such a centralized system the speed and flexibility of the interconnect beco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Department Of Trade And Industry (United Kingdom)
The Department of Trade and Industry (DTI) was a United Kingdom government department formed on 19 October 1970. It was replaced with the creation of the Department for Business, Enterprise and Regulatory Reform and the Department for Innovation, Universities and Skills on 28 June 2007. History The department was first formed on 19 October 1970 with the merger of the Board of Trade and the Ministry of Technology, creating a new cabinet post of Secretary of State for Trade and Industry. The new department also took over the Department of Employment's former responsibilities for monopolies and mergers. In January 1974, the department's responsibilities for energy production were transferred to a newly created Department of Energy. On 5 March that year, following a Labour Party victory in the February 1974 general election, the department was split into the Department of Trade, the Department of Industry and the Department of Prices and Consumer Protection.

MicroVAX
The MicroVAX is a discontinued family of low-cost minicomputers developed and manufactured by Digital Equipment Corporation (DEC). The first model, the MicroVAX I, was introduced in 1983.(announced October 1983) They used processors that implemented the VAX instruction set architecture (ISA) and were succeeded by the VAX 4000. Many members of the MicroVAX family had corresponding VAXstation variants, which primarily differ by the addition of graphics hardware. The MicroVAX family supports Digital's VMS and ULTRIX operating systems. Prior to VMS V5.0, MicroVAX hardware required a dedicated version of VMS named MicroVMS. MicroVAX I The MicroVAX I, code named "''Seahorse''", introduced in October 1984, was one of DEC's first VAX computers to use very-large-scale integration (VLSI) technology. The KA610 CPU module (also known as the KD32) contained two custom chips which implemented the ALU and FPU while TTL chips were used for everything else. Two variants of the floating point ch ...

Fileserver
In computing, a file server (or fileserver) is a computer attached to a network that provides a location for shared disk access, i.e. storage of computer files (such as text, image, sound, video) that can be accessed by the workstations that are able to reach the computer that shares the access through a computer network. The term server highlights the role of the machine in the traditional client–server scheme, where the clients are the workstations using the storage. A file server does not normally perform computational tasks or run programs on behalf of its client workstations. File servers are commonly found in schools and offices, where users use a local area network to connect their client computers. Types of file servers A file server may be dedicated or non-dedicated. A dedicated server is designed specifically for use as a file server, with workstations attached for reading and writing files and databases. File servers may also be categorized by the method of access: I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Multi-user
Multi-user software is computer software that allows access by multiple users of a computer. Time-sharing systems are multi-user systems. Most batch processing systems for mainframe computers may also be considered "multi-user", to avoid leaving the CPU idle while it waits for I/O operations to complete. However, the term " multitasking" is more common in this context. An example is a Unix or Unix-like system where multiple remote users have access (such as via a serial port or Secure Shell) to the Unix shell prompt at the same time. Another example uses multiple X Window sessions spread across multiple terminals powered by a single machine - this is an example of the use of thin client. Similar functions were also available in a variety of non-Unix-like operating systems, such as Multics, VM/CMS, OpenVMS, MP/M, Concurrent CP/M, Concurrent DOS, FlexOS, Multiuser DOS, REAL/32, OASIS, THEOS, PC-MOS, TSX-32 and VM/386. Some multi-user operating systems such as Windows versions fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
