SR (programming Language)
SR (short for Synchronizing Resources) is a programming language designed for concurrent programming. ''Resources'' encapsulate processes and the variables they share, and can be separately compiled. ''Operations'' provide the primary mechanism for process interaction. SR provides a novel integration of the mechanisms for invoking and servicing operations. Consequently, it supports local and remote procedure call, rendezvous, message passing, dynamic process creation, multicast, semaphores and shared memory.

Programming Language
A programming language is a system of notation for writing computer programs. Most programming languages are text-based formal languages, but they may also be graphical. They are a kind of computer language. The description of a programming language is usually split into the two components of syntax (form) and semantics (meaning), which are usually defined by a formal language. Some languages are defined by a specification document (for example, the C programming language is specified by an ISO Standard) while other languages (such as Perl) have a dominant implementation that is treated as a reference. Some languages have both, with the basic language defined by a standard and extensions taken from the dominant implementation being common. Programming language theory is the subfield of computer science that studies the design, implementation, analysis, characterization, and classification of programming languages. Definitions There are many considerations when defini ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Stephen J
Stephen or Steven is a common English first name. It is particularly significant to Christians, as it belonged to Saint Stephen ( grc-gre, Στέφανος ), an early disciple and deacon who, according to the Book of Acts, was stoned to death; he is widely regarded as the first martyr (or "protomartyr") of the Christian Church. In English, Stephen is most commonly pronounced as ' (). The name, in both the forms Stephen and Steven, is often shortened to Steve or Stevie. The spelling as Stephen can also be pronounced which is from the Greek original version, Stephanos. In English, the female version of the name is Stephanie. Many surnames are derived from the first name, including Stephens, Stevens, Stephenson, and Stevenson, all of which mean "Stephen's (son)". In modern times the name has sometimes been given with intentionally non-standard spelling, such as Stevan or Stevon. A common variant of the name used in English is Stephan ; related names that have found some c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ronald A
Ronald is a masculine given name derived from the Old Norse ''Rögnvaldr'',#H2, Hanks; Hardcastle; Hodges (2006) p. 234; #H1, Hanks; Hodges (2003) § Ronald. or possibly from Old English ''Regenweald''. In some cases ''Ronald'' is an Anglicised form of the Gaelic ''Raghnall'', a name likewise derived from ''Rögnvaldr''. The latter name is composed of the Old Norse elements ''regin'' ("advice", "decision") and ''valdr'' ("ruler"). ''Ronald'' was originally used in England and Scotland, where Scandinavian influences were once substantial, although now the name is common throughout the English-speaking world. A short form of ''Ronald'' is ''Ron''. Pet forms of ''Ronald'' include ''Roni'' and ''Ronnie (given name), Ronnie''. ''Ronalda'' and ''Rhonda'' are feminine forms of ''Ronald''. ''Rhona (other), Rhona'', a modern name apparently only dating back to the late nineteenth century, may have originated as a feminine form of ''Ronald''.#H2, Hanks; Hardcastle; Hodges (2006) pp ...

MPD (programming Language)
Multithreaded, Parallel, and Distributed Programming (MPD) is a concurrent programming language whose syntax is derived from the one used in the book ''Foundations of Multithreaded, Parallel, and Distributed Programming''. The name lists the distinguishing features of the language, namely that it supports all three of these concurrent programming techniques. MPD is implemented as a variant of the SR programming language. It has a different parser, but it uses the same intermediate form and run-time system as SR. Consequently, MPD provides the same variety of concurrent programming mechanisms as does SR. MPD programs can execute on single processors, shared-memory multiprocessors, or clusters of (homogeneous) processors. The implementation transparently supports a variety of different kinds of processors and Unix Unix (; trademarked as UNIX) is a family of multitasking, multiuser computer operating systems that derive from the original AT&T Unix, whose development started in ...

Occam (programming Language)
occam is a programming language which is concurrent and builds on the communicating sequential processes (CSP) process algebra, Inmos document 72 occ 45 03 and shares many of its features. It is named after philosopher William of Ockham after whom Occam's razor is named. occam is an imperative procedural language (such as Pascal). It was developed by David May and others at Inmos (trademark INMOS), advised by Tony Hoare, as the native programming language for their transputer microprocessors, but implementations for other platforms are available. The most widely known version is occam 2; its programming manual was written by Steven Ericsson-Zenith and others at Inmos. Overview In the following examples indentation and formatting are critical for parsing the code: expressions are terminated by the end of the line, lists of expressions need to be on the same level of indentation. This feature, named the off-side rule, is also found in other languages such as Haskell and Pytho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sun-4
Sun-4 is a series of Unix workstations and servers produced by Sun Microsystems, launched in 1987. The original Sun-4 series were VMEbus-based systems similar to the earlier Sun-3 series, but employing microprocessors based on Sun's own SPARC V7 RISC architecture in place of the 68k family processors of previous Sun models. Sun 4/280 was known as base system that was used for building of first RAID prototype. Models Models are listed in approximately chronological order. : In 1989, Sun dropped the "Sun-4" name for marketing purposes in favor of the SPARCstation and SPARCserver brands for new models, although early SPARCstation/server models were also assigned Sun-4-series model numbers. For example, the SPARCstation 1 was also known as the Sun 4/60. This practice was phased out with the introduction of the SPARCserver 600MP series in 1991. The term ''Sun-4'' continued to be used in an engineering context to identify the basic hardware architecture of all SPARC-based Sun system ...

SGI IRIS
The SGI IRIS series of terminals and workstations from Silicon Graphics was produced in the 1980s and 1990s. IRIS is an acronym for Integrated Raster Imaging System. Overview 68000 The early systems up to IRIS 3000 use the Motorola 68000 series of processors originally, and later models feature early-generation MIPS processors. These systems run the GL2 operating system, a predecessor of the IRIX operating system, which is based on UniSoft UniPlus System V Unix. GL2 uses a proprietary windowing system named MEX (windowing system), mex (Multiple EXposure). The first model, the IRIS 1000, was shipped around November 1983 with an 8 MHz Motorola 68000 CPU. It is a graphics terminal intended to be attached to a VAX-11 system running either VAX/VMS or BSD Unix. The related IRIS 1200 terminal has a 20-slot backplane in its cabinet versus the 10-slot backplane of the IRIS 1000. The IRIS 1400 Workstation (also known as the IRIS Workstation) was shipped only in 1984. It has a 10 MHz Moto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sequent Computer Systems
Sequent Computer Systems was a computer company that designed and manufactured multiprocessing computer systems. They were among the pioneers in high-performance symmetric multiprocessing (SMP) open systems, innovating in both hardware (e.g., cache management and interrupt handling) and software (e.g., read-copy-update). Through a partnership with Oracle Corporation, Sequent became a dominant high-end UNIX platform in the late 1980s and early 1990s. Later they introduced a next-generation high-end platform for UNIX and Windows NT based on a non-uniform memory access architecture, NUMA-Q. As hardware prices fell in the late 1990s, and Intel shifted their server focus to the Itanium processor family, Sequent joined the Project Monterey effort in October 1998. which aimed to move a standard Unix to several new platforms.

RS/6000
The RISC System/6000 (RS/6000) is a family of Reduced instruction set computer, RISC-based Unix Server (computing), servers, workstations and supercomputers made by IBM in the 1990s. The RS/6000 family replaced the IBM RT PC computer platform in February 1990 and was the first computer line to see the use of IBM's IBM Power microprocessors, POWER and PowerPC based microprocessors. In October 2000, the RS/6000 brand was retired for POWER-based servers and replaced by the pSeries, eServer pSeries. Workstations continued under the RS/6000 brand until 2002, when new POWER-based workstations were released under the IntelliStation POWER brand. History The first RS/6000 models used the Micro Channel architecture, Micro Channel bus, later models used Peripheral Component Interconnect, PCI. Some later models conformed to the PReP and Common Hardware Reference Platform, CHRP standard platforms, which were co-developed with Apple Inc., Apple and Motorola, with Open Firmware.
