Announced in July 2011 by the National Science Foundation, the Extreme Science and Engineering Discovery Environment (XSEDE) project links computers, data, and people from around the world to establish a single, virtual system that scientists can interactively use to conduct research. A partnership of 17 institutions, this project provides researchers with open access to the power of supercomputers, advanced computational tools and digital resources and services directly from their desktops. Funded by the NSF for five years at $121 million, XSEDE is to be the most advanced, powerful, and robust collection of integrated advanced digital resources and services in the world. XSEDE replaces and expands the TeraGrid project that started a decade ago. More than 10,000 scientists used the TeraGrid to complete thousands of research projects.

Purdue was a service provider to the XSEDE project until late 2013, operating an HPC cluster (Steele), a high-throughput computing resource (the Purdue HTCondor pool, BoilerGrid), and a cloud resource (Wispy) and provides access and support to XSEDE users. Purdue staff continue to also play the following roles in the project:

  • Providing expertise and advanced technical assistance to XSEDE users.
  • Leading the XSEDE Campus Champion Program to further expand the XSEDE user base by reaching out to campuses, providing training and outreach activities, and getting feedback from campus users to improve XSEDE services.
  • Providing an XSEDE–OSG (Open Science Grid) liaison to bridge the efforts of the two cyberinfrastructure projects by assisting users in utilizing both the XSEDE and OSG resources, identifying and organizing training and outreach activities to broaden the user base.
