Open Science Grid Consortium
{{Short description|Distributed computing organization}}
The Open Science Grid Consortium is an organization that administers a worldwide 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.
Use
The OSG is used by scientists and researchers for data analysis tasks which are too computationally intensive for a single data center or supercomputer. While most of the grid's resources are used for particle physics, research teams from disciplines like biology, chemistry, astronomy, and geographic information systems are currently using the grid to analyze data. Research using the grid's resources has been published in the Journal of Physical Chemistry.{{Cite journal

=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.{{cite web|last=Gaudin |first=Sharon |title=Collider probes universe's mysteries at the speed of light |work=ComputerWorld |access-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}} 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.{{cite web|last=Shread |first=Paul |title=Open Science Grid Consortium Declares Grid3 A Success |work=GridComputingPlanet |access-date=2009-03-02 |date=2004-11-21 |url=http://www.gridcomputingplanet.com/news/article.php/3410901 |url-status=dead |archive-url=https://web.archive.org/web/20070715040524/http://www.gridcomputingplanet.com/news/article.php/3410901 |archive-date=July 15, 2007 }}|Robert Gardner, Senior Research Associate at The University of Chicago}}
Architecture
{{as of|2008}}, the OSG comprises over 25,000 computers with over 43,000 processors, most of which are running a distribution of Linux.{{cite web|last=Gaudin |first=Sharon |title=Worldwide grid evaluating collider test results |work=InfoWorld |access-date=2009-03-02 |date=2008-11-15 |url=http://www.infoworld.com/news/feeds/08/09/15/Worldwide-grid-evaluating-collider-test-results.html }}{{dead link|date=June 2016|bot=medic}}{{cbignore|bot=medic}} 72 institutions, including 42 universities, are consortium members who contribute resources to the grid.{{cite web|title=Members and Partners |access-date=2009-03-02 |url=http://www.opensciencegrid.org/About/Learn_About_Us/OSG_Organization/Members_and_Partners |url-status=dead |archive-url=https://web.archive.org/web/20090313033647/http://www.opensciencegrid.org/About/Learn_About_Us/OSG_Organization/Members_and_Partners |archive-date=March 13, 2009 }} There are 90 distinct computational and storage nodes in the grid, which are distributed across the United States and Brazil.{{cite web
