Science Gateways on the TeraGrid A survey of issues for deployment of community gateway interfaces to shared high-end computing resources Charlie Catlett, Sebastien Goasguen, Jim Marsteller, Stuart Martin, Don Middleton, Kevin J. Price, Anurag Shankar, Von Welch, Nancy Wilkins-Diehr November 2006 Abstract Increasingly, the scientific community has been using web portals and desktop applications to organize their work. The TeraGrid team determined that it would be important to create a set of capabilities that would allow TeraGrid services and resources to be integrated, potentially in a transparent way, with these scientific computing environments. This paper outlines the “Science Gateways” program and provides an overview of key lessons learned in developing mechanisms to allow for such integration.
