To pool computational resources spread around Indiana and the Midwest, DiaGrid takes advantage of I-Light, the high-speed fiber-optic state network connecting Indiana campuses to each other, the Internet and national research networks such as the Internet2 and National LambdaRail. DiaGrid provides computational resources to researchers on both the Open Science Grid and the U.S. National Science Foundation's Extreme Science and Engineering Discovery Environment system (formerly TeraGrid).
