The OSG includes two grids: an Integration Grid and a Production Grid. The Integration Grid is used to test new grid applications, sites and technologies, while the Production Grid provides a stable, supported environment on which researchers run their scientific applications.

The National Science Foundation (NSF) and the Department of Energy’s (DOE) Office of Science announced today that they have joined forces to fund a five-year, $30 million program to operate and expand upon the two-year-old national grid.
