Khornerstone
In computer performance testing, Khornerstone is a multipurpose benchmark from Workstation Labs used in various periodicals such as ''UNIX Review''. The benchmark consists of 22 separate tests, including public domain components (such as Sieve and Dhrystone Dhrystone is a synthetic computing benchmark program developed in 1984 by Reinhold P. Weicker intended to be representative of system (integer) programming. The Dhrystone grew to become representative of general processor ( CPU) performance. T ...) as well as proprietary components. Since it contains proprietary components, the source is not free. The results of the 22 tests are normalized, producing a result measured in "Khornerstones". The benchmark was introduced in 1986 and was commonly used until the mid-1990s. References Benchmarks (computing) {{unix-stub ...

Benchmark (computing)
In computing, a benchmark is the act of running a computer program, a set of programs, or other operations, in order to assess the relative Computer performance, performance of an object, normally by running a number of standard Software performance testing, tests and trials against it. The term ''benchmark'' is also commonly utilized for the purposes of elaborately designed benchmarking programs themselves. Benchmarking is usually associated with assessing performance characteristics of computer hardware, for example, the floating point operation performance of a Central processing unit, CPU, but there are circumstances when the technique is also applicable to software. Software benchmarks are, for example, run against compilers or database management systems (DBMS). Benchmarks provide a method of comparing the performance of various subsystems across different chip/system Computer architecture, architectures. Purpose As computer architecture advanced, it became more diffi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
UNIX Review
''UNIX Review'' was an American magazine covering technical aspects of the UNIX operating system and C programming. Recognized for its in-depth technical analysis, the journal also reported on industry confabs and included some lighter fare. History and profile It was founded in 1983. In 1985 it was acquired by Miller Freeman. The journal was renamed to ''UNIX Review's Performance Computing (UR/PC) Magazine'' with the April 1998 issue, and ceased publication in 2000. The online publication ceased in 2007. It was published by REVIEW Publications of Renton, Washington. The rights to the title passed to United Business Media (formerly CMP Media), which was absorbed by Informa in 2018. Regular contributors *Andrew Binstock, (editor in chief from 1991–1997), wrote "Word Wrap from the Editor" *John Chisholm (1992-1995), wrote "Currents" column * Stan Kelly-Bootle, writer of the "Devil's Advocate" column *Ken Arnold, writer of "The C Advisor" column *Rich Morin, writer of "The Human F ...

Sieve (benchmark)
A sieve, fine mesh strainer, or sift, is a device for separating wanted elements from unwanted material or for controlling the particle size distribution of a sample, using a screen such as a woven mesh or net or perforated sheet material. The word ''sift'' derives from ''sieve''. In cooking, a sifter is used to separate and break up clumps in dry ingredients such as flour, as well as to aerate and combine them. A strainer (see Colander), meanwhile, is a form of sieve used to separate suspended solids from a liquid by filtration. Industrial strainer Some industrial strainers available are simplex basket strainers, duplex basket strainers, T-strainers and Y-strainers. Simple basket strainers are used to protect valuable or sensitive equipment in systems that are meant to be shut down temporarily. Some commonly used strainers are bell mouth strainers, foot valve strainers, basket strainers. Most processing industries (mainly pharmaceutical, coatings and liquid food indust ...

Dhrystone
Dhrystone is a synthetic computing benchmark program developed in 1984 by Reinhold P. Weicker intended to be representative of system (integer) programming. The Dhrystone grew to become representative of general processor ( CPU) performance. The name "Dhrystone" is a pun on a different benchmark algorithm called Whetstone (pun explained: w''h''et-stone = wet-stone , d''h''ry-stone = dry-stone), which emphasizes floating point performance. With Dhrystone, Weicker gathered meta-data from a broad range of software, including programs written in FORTRAN, PL/1, SAL, ALGOL 68, and Pascal. He then characterized these programs in terms of various common constructs: procedure calls, pointer indirections, assignments, etc. From this he wrote the Dhrystone benchmark to correspond to a representative mix. Dhrystone was published in Ada, with the C version for Unix developed by Rick Richardson ("version 1.1") greatly contributing to its popularity. Dhrystone vs. Whetstone The Dhrysto ...

Free Software
Free software or libre software is computer software distributed under terms that allow users to run the software for any purpose as well as to study, change, and distribute it and any adapted versions. Free software is a matter of liberty, not price; all users are legally free to do what they want with their copies of a free software (including profiting from them) regardless of how much is paid to obtain the program.Selling Free Software (gnu.org) Computer programs are deemed "free" if they give end-users (not just the developer) ultimate control over the software and, subsequently, over their devices. The right to study and modify a computer program entails that |
