It is the goal of this workshop series to provide a venue for researchers to present pioneering, peer-reviewed work on all topics related to gateways. We hope to provide an interactive forum, including lightning talks, posters, and opportunities to share common experiences. Leveraging knowledge about common tasks can free gateway developers to focus on higher-level, grand-challenge functionality in their discipline. Our featured keynote speaker will be Charlie Catlett, director of the Urban Center for Computation and Data (UrbanCCD) at the Computation Institute of the University of Chicago and Argonne National Laboratory. The Center brings scientists from mathematics and computing together with social, behavioral, economic, policy, education, and health scientists to support research in urban sciences. He’s a Senior Computer Scientist at Argonne National Laboratory, where he also served as Chief Information Officer from 2007-2011. Charlie is a Senior Fellow at the Computation Institute of the University of Chicago and Argonne and a Visiting Artist at the School of Art Insitute of Chicago. From 2004-2007, Charlie directed the NSF TeraGrid project and from 1999-2004 he was the founding chair of the Global Grid Forum (now the Open Grid Forum). Proceedings of the workshop will be published in the ACM Digital Library, and accepted authors will have the opportunity to publish extended versions of their submissions in a special journal issue sponsored jointly with the International Workshop on Science Gateways (IWSG, hosted at Trinity College, Dublin, from June 3-5, 2014). Details of the special issue are below.
