Purpose. Simulation, analysis, and government security applications. Tianhe-2 or TH-2 (Chinese: 天河-2; pinyin: tiānhé-èr; lit. 'Heavenriver-2', i.e. ' Milky Way 2') is a 3.86- petaflop supercomputer located in the National Supercomputer Center in Guangzhou, China. [3] It was developed by a team of 1,300 scientists and engineers.
In computer science and computer engineering, computer architecture is a description of the structure of a computer system made from component parts. [1] It can sometimes be a high-level description that ignores details of the implementation. [2] At a more detailed level, the description may include the instruction set architecture design ...
The von Neumann architecture —also known as the von Neumann model or Princeton architecture —is a computer architecture based on a 1945 description by John von Neumann, and by others, in the First Draft of a Report on the EDVAC. [1] The document describes a design architecture for an electronic digital computer with these components: The ...
Supercomputer architecture. Approaches to supercomputer architecture have taken dramatic turns since the earliest systems were introduced in the 1960s. Early supercomputer architectures pioneered by Seymour Cray relied on compact innovative designs and local parallelism to achieve superior computational peak performance. [1]
Conway's law. Conway's law describes the link between communication structure of organizations and the systems they design. It is named after the computer programmer Melvin Conway, who introduced the idea in 1967. [1] His original wording was: [2][3] [O]rganizations which design systems (in the broad sense used here) are constrained to produce ...
In computer architecture, the memory hierarchy separates computer storage into a hierarchy based on response time. Since response time, complexity, and capacity are related, the levels may also be distinguished by their performance and controlling technologies. [1] Memory hierarchy affects performance in computer architectural design, algorithm ...
Flynn's taxonomy is a classification of computer architectures, proposed by Michael J. Flynn in 1966 [1] and extended in 1972. [2] The classification system has stuck, and it has been used as a tool in the design of modern processors and their functionalities. Since the rise of multiprocessing central processing units (CPUs), a multiprogramming ...
Ivory seal of Godwin, an unknown thegn – first half of eleventh century, British Museum. In later Anglo-Saxon England, a thegn (pronounced / θeɪn /; Old English: þeġn) or thane[ 1 ] (or thayn in Shakespearean English) was an aristocrat who owned substantial land in one or more counties. Thanes ranked at the third level in lay society ...
