The Extreme Science and Engineering Discovery Environment (XSEDE) is the most advanced, 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, collections of data, and new tools—to make our lives healthier, safer, and better. XSEDE, and the experts who lead the program, will make these resources easier to use and help more people use them.

The five-year, $110-million project is supported by the National Science Foundation. In summer of 2016, the NSF announced that XSEDE was awarded an additional 5 years of funding after the first 5-year award completed. Originally, XSEDE replaced and expanded on the NSF TeraGrid project. More than 10,000 scientists used the TeraGrid to complete thousands of research projects, at no cost to the scientists.

That same sort of work—only in more detail, generating more new knowledge and improving our world in an even broader range of fields—continues with XSEDE. Find out how to get an allocation to use XSEDE resources.

A key to researchers' success using XSEDE supercomputers is the collection of computational science experts who help move a project along. This help service is called Extended Collaborative Support Service (ECSS). Find out more about ECSS here.

XSEDE lowers technological barriers to the access and use of computing resources. Using XSEDE, researchers can establish private, secure environments that have all the resources, services, and collaboration support they need to be productive. Find out more about the resources and services available through XSEDE.

XSEDE supports 13 supercomputers and high-end visualization and data analysis resources across the country. It 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 California San Diego and many others.
