The Extreme Science and Engineering Discovery Environment (XSEDE)

The Extreme Science and Engineering Discovery Environment (XSEDE) is the most powerful and robust collection of integrated advanced digital resources and services in the world. It is a single virtual system that scientists can use to interactively share computing resources, data, and expertise.

Scientists and engineers around the world use these resources and services - things like supercomputers, visualization and data analysis systems and tools, and data collections - to propel scientific discovery and improve our lives. They are a crucial part of research in fields like earthquake modeling, materials science, medicine, epidemiology, genomics, astronomy, and biology.

NSF will fund the XSEDE project for five years at a cost of $121 million. XSEDE replaces and expands on the NSF TeraGrid project. Over the course of a decade, more than 10,000 scientists used the TeraGrid to complete thousands of research projects, at no cost to the scientists.

TACC is one of the leading partners in the new XSEDE project, whose resources include more than one petaflop of computing capability and more than 30 petabytes of online and archival data storage. As part of the project, TACC provides access to Ranger, Lonestar, Longhorn, Spur, and Ranch through XSEDE quarterly allocations. Staff at the center support XSEDE researchers nationwide, and perform research and development to make XSEDE more effective and impactful.

Initially, XSEDE supports 16 supercomputers across the country. The project also includes other specialized digital resources and services to complement these computers. These resources will be expanded throughout the lifetime of the project.

The XSEDE partnership includes: University of Illinois at Urbana-Champaign, Carnegie Mellon University/University of Pittsburgh, University of Texas at Austin, University of Tennessee Knoxville, University of Virginia, Shodor Education Foundation, Southeastern Universities Research Association, University of Chicago, University of California San Diego, Indiana University, J├╝lich Supercomputing Centre, Purdue University, Cornell University, Ohio State University, University of California Berkeley, Rice University, and the National Center for Atmospheric Research. It is led by the University of Illinois's National Center for Supercomputing Applications.
