Cybil (programming Language)
Cybil (short for the Cyber Implementation Language of the Control Data Network Operating System) was a Pascal-like language developed at Control Data Corporation for the Cyber computer family. Cybil was used as the implementation language for the NOS/VE operating system based on a CDC NOS/VE information leaflet on the series and was also used to write the operating system for the |
Pascal (programming Language)
Pascal is an imperative and procedural programming language, designed by Niklaus Wirth as a small, efficient language intended to encourage good programming practices using structured programming and data structuring. It is named in honour of the French mathematician, philosopher and physicist Blaise Pascal. Pascal was developed on the pattern of the ALGOL 60 language. Wirth was involved in the process to improve the language as part of the ALGOL X efforts and proposed a version named ALGOL W. This was not accepted, and the ALGOL X process bogged down. In 1968, Wirth decided to abandon the ALGOL X process and further improve ALGOL W, releasing this as Pascal in 1970. On top of ALGOL's scalars and arrays, Pascal enables defining complex datatypes and building dynamic and recursive data structures such as lists, trees and graphs. Pascal has strong typing on all objects, which means that one type of data cannot be converted to or interpreted as another without explicit conversi ...

Control Data Corporation
Control Data Corporation (CDC) was a mainframe and supercomputer firm. CDC was one of the nine major United States computer companies through most of the 1960s; the others were IBM, Burroughs Corporation, DEC, NCR, General Electric, Honeywell, RCA, and UNIVAC. CDC was well-known and highly regarded throughout the industry at the time. For most of the 1960s, Seymour Cray worked at CDC and developed a series of machines that were the fastest computers in the world by far, until Cray left the company to found Cray Research (CRI) in the 1970s. After several years of losses in the early 1980s, in 1988 CDC started to leave the computer manufacturing business and sell the related parts of the company, a process that was completed in 1992 with the creation of Control Data Systems, Inc. The remaining businesses of CDC currently operate as Ceridian. Background and origins: World War II–1957 During World War II the U.S. Navy had built up a classified team of engineers to build codeb ...

CDC Cyber
The CDC Cyber range of mainframe-class supercomputers were the primary products of Control Data Corporation (CDC) during the 1970s and 1980s. In their day, they were the computer architecture of choice for scientific and mathematically intensive computing. They were used for modeling fluid flow, material science stress analysis, electrochemical machining analysis, probabilistic analysis, energy and academic computing, radiation shielding modeling, and other applications. The lineup also included the Cyber 18 and Cyber 1000 minicomputers. Like their predecessor, the CDC 6600, they were unusual in using the ones' complement binary representation. Models The Cyber line included five different series of computers: * The 70 and 170 series based on the architecture of the CDC 6600 and CDC 7600 supercomputers, respectively * The 200 series based on the CDC STAR-100 - released in the 1970s. * The 180 series developed by a team in Canada - released in the 1980s (after the 200 series) ...

NOS/VE
NOS/VE (Network Operating System / Virtual Environment) is a discontinued operating system with time-sharing capabilities, written by Control Data Corporation in the 1980s. It is a virtual memory operating system, employing the 64-bit virtual mode of the CDC Cyber 180 series computers. NOS/VE replaced the earlier NOS and NOS/BE operating systems of the 1970s. Commands The command shell interface for NOS/VE is called the ''System Command Language'', or SCL for short. In order to be callable from SCL, command programs must declare their parameters; this permits automatic usage summaries, passing of parameters by name or by position, and type checking on the parameter values. All standard NOS/VE commands further follow a particular naming convention, where the form of the command is ''verb''_''noun''; these commands could be abbreviated with the first three characters of the verb followed by the first character(s) of all further words. Examples: Inspired by addressing structure-m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
EOS (operating System)
The ETA10 is a vector supercomputer designed, manufactured, and marketed by ETA Systems, a spin-off division of Control Data Corporation (CDC). The ETA10 was an evolution of the CDC Cyber 205, which can trace its origins back to the CDC STAR-100, one of the first vector supercomputers to be developed. CDC announced it was creating ETA Systems, and a successor to the Cyber 205, on 18 April 1983 at the Frontiers of Supercomputing conference, held at the Los Alamos National Laboratory. It was then referred to tentatively as the Cyber 2XX, and later as the GF-10, before it was named the ETA10. Prototypes were operational in mid-1986, and the first delivery was made in December 1986. The supercomputer was formally announced in April 1987 at an event held at its first customer installation, the Florida State University, Tallahassee's Scientific Computational Research Institute. On 17 April 1989, CDC abruptly closed ETA Systems due to ongoing financial losses, and discontinued produc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
