What is the Open Science Grid?

The Open Science Grid (OSG) is a distributed computing infrastructure for large-scale scientific research, built and operated by a consortium of universities, national laboratories, scientific collaborations, and software developers. The OSG enables scientists to seamlessly harness grid-computing resources worldwide, and interoperates with multiple other grid infrastructures.

The OSG is supported by the National Science Foundation and the US Department of Energy's Office of Science. It is a continuation of the Grid3, NaGrid Physics Network (GriPhyN), and International Virtual Data Grid Laboratory (iVDGL) projects, and the Particle Physics Data Grid (PPDG) project.
