What are the XSEDE and XSEDE 2.0 projects?
The Extreme Science and Engineering Discovery Environment (XSEDE) is an advanced cyberinfrastructure project and virtual organization committed to enabling and accelerating transformative open science and engineering research.
Originally a five-year, $121 million National Science Foundation (NSF) grant awarded to the National Center for Supercomputing Applications (NCSA) at the University of Illinois and its partner institutions via program solicitation NSF 08-571, XSEDE is the successor to the NSF-funded TeraGrid project, which itself succeeded the NSF supercomputer center program that began in the 1980s.
In August 2016, the NSF announced a five-year, $110 million award for funding XSEDE 2.0, a new phase of the project that began on September 1, 2016. Formally called "XSEDE 2.0: Integrating, Enabling and Enhancing National Cyberinfrastructure with Expanding Community Involvement", the project focuses on expanding community involvement, investigating and implementing innovative elements to accommodate evolving user demand and emerging technologies, and building on previous successes by continuing to provide high-performance computing, visualization, and storage systems, state-of-the art software, expert operations and support professionals, and training, education, and outreach programs that enhance the productivity and capabilities of a growing national community of scientists, engineers, educators, and students.
John Towns, Deputy CIO for Research IT at the University of Illinois at Urbana-Champaign, is principal investigator for the XSEDE 2.0 project.
