Fhourstones
In computer science, Fhourstones is an integer benchmark that efficiently solves positions in the game of Connect-4. It was written by John Tromp in 1996-2008, and is incorporated into the Phoronix Test Suite. The measurements are reported as the number of game positions searched per second. Available in both ANSI-C and Java, it is quite portable and compact (under 500 lines of source), and uses 50Mb of memory. The benchmark involves (after warming up on three easier positions) solving the entire game, which takes about ten minutes on contemporary PCs, scoring between 1000 and 12,000 kpos/sec. It has been described as more realistic than some other benchmarks.{{cite book, title=Embedded Software: Second International Conference, EMSOFT 2002, date=2003, publisher=Springer, page=208 Fhourstones was named as a pun on Dhrystone Dhrystone is a synthetic computing benchmark program developed in 1984 by Reinhold P.

Connect Four
Connect Four (also known as Connect 4, Four Up, Plot Four, Find Four, Captain's Mistress, Four in a Row, Drop Four, and Gravitrips in the Soviet Union) is a two-player connection board game, in which the players choose a color and then take turns dropping colored tokens into a seven-column, six-row vertically suspended grid. The pieces fall straight down, occupying the lowest available space within the column. The objective of the game is to be the first to form a horizontal, vertical, or diagonal line of four of one's own tokens. Connect Four is a solved game. The first player can always win by playing the right moves. The game was first sold under the ''Connect Four'' trademark by Milton Bradley in February 1974. Gameplay A gameplay example (right), shows the first player starting Connect Four by dropping one of their yellow discs into the center column of an empty game board. The two players then alternate turns dropping one of their discs at a time into an unfilled colum ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Phoronix Test Suite
Phoronix Test Suite (PTS) is a free and open-source benchmark software for Linux and other operating systems which is developed by Michael Larabel and Matthew Tippett. The Phoronix Test Suite has been endorsed by sites such as Linux.com, LinuxPlanet, and Softpedia. Features * Supports over 220 test profiles and over 60 test suites; * Uses an XML-based testing architecture. Tests include MEncoder, FFmpeg and lm sensors along with OpenGL games such as ''Doom 3'', ''Nexuiz'', and '' Enemy Territory: Quake Wars'', and many more. * Contains a feature called PTS Global where users are able to upload their test results and system information for sharing. Then through executing a single command, other users can compare their test results to a selected system in an easy-comparison mode; * Allows report benchmark results to the Phoronix Global online database; * Allows to compare results side-by-side; * Is extensible and new tests can be added easily * Can do anonymous usage reporting; ...

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 ...

Whetstone (benchmark)
The Whetstone benchmark is a synthetic Benchmark (computing), benchmark for evaluating the performance of computers. It was first written in Algol 60 in 1972 at the Technical Support Unit of the Department of Trade and Industry (later part of the Central Computer and Telecommunications Agency) in the United Kingdom. It was derived from statistics on program behaviour gathered on the KDF9 computer at NPL National Physical Laboratory, UK, National Physical Laboratory, using a modified version of its Whetstone ALGOL 60 compiler. The workload on the machine was represented as a set of frequencies of execution of the 124 instructions of the Whetstone Code. The Whetstone Compiler was built at the Atomic Power Division of the English Electric Company in Whetstone, Leicestershire, England, hence its name. Dr. B.A. Wichman at NPL produced a set of 42 simple ALGOL 60 statements, which in a suitable combination matched the execution statistics. To make a more practical benchmark Harold Curnow ...
