{{Short description|Distributed computing organization}}

The '''Open Science Grid Consortium''' is an organization that administers a worldwide [[grid computing|grid]] of technological resources called the '''Open Science Grid''', which facilitates [[distributed computing]] for scientific research. Founded in 2004, the [[consortium]] is composed of service and resource providers, researchers from universities and national laboratories, as well as computing centers across the United States. Members independently own and manage the resources which make up the distributed facility, and consortium agreements provide the framework for technological and organizational integration.

===Large Hadron Collider===

The Open Science Grid was created in order to facilitate data analysis from the [[Large Hadron Collider]], and about 70% of its 300,000 computing-hours per day are dedicated to the analysis of data from particle colliders.<ref>{{cite web|last=Gaudin |first=Sharon |title=Collider probes universe's mysteries at the speed of light |work=ComputerWorld |accessdateaccess-date=2009-03-02 |date=2008-11-09 |url=http://www.infoworld.com/news/feeds/08/09/09/Collider-probes-universes-mysteries-at-the-speed-of-light.html }}{{dead link|date=June 2016|bot=medic}}{{cbignore|bot=medic}}</ref> Once data has been collected and distributed by the [[LHC Computing Grid]], the Open Science Grid assists physicists from institutions around the world in analysis. The grid has been designed so that resources and data are shared automatically: {{quote|It's really driven not so much by where the physicists come from, but what their interests are. Physicists will be able to submit jobs to this distributed network of centers and not worry about which center that their job is actually going to run on, because the data for their task will already be there.<ref>{{cite web|last=Shread |first=Paul |title=Open Science Grid Consortium Declares Grid3 A Success |work=GridComputingPlanet |accessdateaccess-date=2009-03-02 |date=2004-11-21 |url=http://www.gridcomputingplanet.com/news/article.php/3410901 |deadurlurl-status=yesdead |archiveurlarchive-url=httphttps://web.archive.org/web/20070715040524/http://www.gridcomputingplanet.com/news/article.php/3410901 |archivedatearchive-date=July 15, 2007 }}</ref>|Robert Gardner, Senior Research Associate at [[The University of Chicago]]}}

===Peerage===

The grid is [[Peer-to-peer|peered]] with other grids, including [[TeraGrid]], [[LHC Computing Grid]], the [[European Grid Infrastructure]], and the [[XSEDEExtreme Science and Engineering Discovery Environment]] (XSEDE),<ref>{{cite web|title=Open Science Grid User Guide |url=https://www.xsede.org/osg-user-guide |deadurlurl-status=yesdead |archiveurlarchive-url=httphttps://web.archive.org/web/20140808051302/https://www.xsede.org/osg-user-guide |archivedatearchive-date=August 8, 2014 }}</ref> allowing data and resources from those grids to be shared.
