XSEDE – Creating an Open Cyberinfrastructure Ecosystem


Since its start in 2001, the TeraGrid has developed into a world-class integrated, national-scale computational science infrastructure with strong international connections and collaborations under funding from the NSF’s Office of Cyberinfrastructure (OCI). Last June, the TeraGrid project came to an end and has been succeeded by the NSF’s eXtreme Digital program and the XSEDE project opening a new chapter in cyberinfrastructure by creating the most advanced, powerful, and robust collection of integrated advanced digital resources and services in the world. This talk will introduce the new project, XSEDE: the eXtreme Science and Engineering Discovery Environment, which began July 1, 2011, and will discuss several aspects of the project including an overview of the distributed systems architecture and discussion of science support activities, connections to campuses, and interactions with international partners.
John Towns, An HPC Innovator

John Towns is the Director of the Distributed Cyberinfrastructure Program Office at NCSA. He is also the PI and Project Director for XSEDE (Extreme Science and Engineering Discovery Environment) and leads other projects at NCSA. He has gained a broad view of the needs of computational and data-intensive science and engineering researchers through his key roles in policy and program development and implementation as part of several large-scale NSF projects as well as his involvement in key activities at the University of Illinois.

His background is in computational astrophysics making use of a variety of computational architectures with a focus on application performance analysis. At NCSA, he provides leadership and direction in the support of an array of computational science and engineering research projects making use of advanced computing and data resources.

Towns plays significant roles in the deployment and operation of computational, data, and visualization resources, and Grid-related projects which embody the deployment of technologies and services to support the establishment of a distributed computing infrastructure.
