Extreme Science and Engineering Discovery Environment


The NSF Extreme Science and Engineering Discovery Environment (XSEDE) is the most powerful and robust collection of integrated advanced digital resources and services in the world. This single virtual system gives scientists, engineers and humanities scholars access to the advanced digital resources and services that propel scientific discoveries and improve the overall quality of our lives.

TACC is one of the leading contributors to XSEDE providing advanced computing and data storage systems, technical expertise, user support and training.

The XSEDE project replaces and expands on the NSF TeraGrid initiative. Over the course of a decade, more than 10,000 scientists used the TeraGrid to complete thousands of research projects.

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