Open Science Grid
http://www.opensciencegrid.org/

The Open Science Grid is a distributed computing infrastructure for large-scale scientific research. It is built and operated by a consortium of universities, national laboratories, scientific collaborations and software developers. The OSG is supported by the National Science Foundation and the U.S. Department of Energy’s Office of Science. The OSG Consortium’s unique alliance of universities, national laboratories, scientific collaborations and software developers brings petascale computing and storage resources into a uniform shared cyberinfrastructure. Members of the OSG Consortium contribute effort and resources to the OSG infrastructure and reap the benefits of a shared infrastructure that integrates computing and storage resources from more than 50 sites in the United States, Asia and South America. OSG also has partners, including campus, regional, national and international grids. Researchers from many fields, including astrophysics, bioinformatics, computer science, medical imaging, nanotechnology and physics use the OSG infrastructure to advance their research. OSG provides help for new communities to adapt their applications to use the distributed facility and make their resources accessible. The OSG also works to enable scientists to seamlessly harness grid-computing resources worldwide and interoperates with multiple other Grid infrastructures. The OSG is a continuation of Grid3, a community grid built in 2003 as a joint project of the U.S. LHC software and computing programs, the National Science Foundation’s Grid Physics Network (GriPhyN) and International Virtual Data Grid Laboratory (iVDGL) projects, and the U.S. Department of Energy’s Particle Physics Data Grid (PPDG) project.
