'''Grid computing''' is the use of widely distributed [[computer]] [[System resource|resources]] to reach a common goal. A computing grid can be thought of as a [[distributed system]] with non-interactive workloads that involve many files. Grid computing is distinguished from conventional high-performance computing systems such as [[Cluster (computing)|cluster]] computing in that grid computers have each node set to perform a different task/application. Grid computers also tend to be more [[heterogeneous]] and geographically dispersed (thus not physically coupled) than cluster computers.<ref>[http://www.e-sciencecity.org/EN/gridcafe/what-is-the-grid.html What is grid computing? - Gridcafe] {{Webarchive|url=https://web.archive.org/web/20130210072831/http://www.e-sciencecity.org/EN/gridcafe/what-is-the-grid.html |date=2013-02-10 }}.

Grids are often constructed with general-purpose grid [[middleware]] software libraries. Grid sizes can be quite large.<ref>{{cite web|url=http://www.networkworld.com/article/2339444/software/scale-grid-computing-down-to-size.html |title=Scale grid computing down to size |publisher=NetworkWorld.com |date=2003-01-27 |access-date=2015-04-21}}</ref>

Grids are a form of [[distributed computing]] whereby a "super virtual computer" is composed of many networked [[Loose coupling|loosely coupled]] computers acting together to perform large tasks. For certain applications, distributed or grid computing can be seen as a special type of [[parallel computing]] that relies on complete computers (with onboard CPUs, storage, power supplies, network interfaces, etc.) connected to a [[computer network]] (private or public) by a conventional [[Network interface controller|network interface]], such as [[Ethernet]]. This is in contrast to the traditional notion of a [[supercomputer]], which has many processors connected by a local high-speed [[computer bus]]. This technology has been applied to computationally intensive scientific, mathematical, and academic problems through [[volunteer computing]], and it is used in commercial enterprises for such diverse applications as [[drug discovery]], [[economic forecasting]], [[seismic analysis]], and [[back office]] data processing in support for [[e-commerce]] and [[Web service]]s.

Grid computing combines computers from multiple administrative domains to reach a common goal,<ref name="autogenerated1">{{cite web|url=http://dlib.cs.odu.edu/WhatIsTheGrid.pdf|title=What is the Grid? A Three Point Checklist}}</ref> to solve a single task, and may then disappear just as quickly. The size of a grid may vary from small—confined to a network of computer workstations within a corporation, for example—to large, public collaborations across many companies and networks. "The notion of a confined grid may also be known as an intra-nodes cooperation whereas the notion of a larger, wider grid may thus refer to an inter-nodes cooperation".<ref>{{cite web |url=http://diuf.unifr.ch/pai/wiki/doku.php?id=Publications&page=publication&kind=single&ID=276 |title=Pervasive and Artificial Intelligence Group :: publications [Pervasive and Artificial Intelligence Research Group&#93; |publisher=Diuf.unifr.ch |date=May 18, 2009 |access-date=July 29, 2010 |archive-url=https://web.archive.org/web/20110707004350/http://diuf.unifr.ch/pai/wiki/doku.php?id=Publications&page=publication&kind=single&ID=276 |archive-date=July 7, 2011 |url-status=dead }}</ref>
