Simplifying Construction of Complex Workflows for Non-Expert Users of the Southern California Earthquake Center Community Modeling Environment Philip Maechling, Gaurang Mehta, Brian Mendenhall, Thomas Russ, Gurmeet Singh, Marc Spraragen, Garrick Staples, Karan Vahi, Hans Chalupsky, Maureen Dougherty, Ewa Deelman, Yolanda Gil, Sridhar Gullapalli, Vipin Gupta, Carl Kesselman, and Jihic Kim   View Paper (PDF)   Return to September 2005, Volume 34, Number 3 Abstract Workflow systems often present the user with rich interfaces that express all the capabilities and complexities of the application programs and the computing environments that they support. However, non-expert users are better served with simple interfaces that abstract away system complexities and still enable them to construct and execute complex workflows. To explore this idea, we have created a set of tools and interfaces that simplify the construction of workflows. Implemented as part of the Community Modeling Environment developed by the Southern California Earthquake Center, these tools, are integrated into a comprehensive workflow system that supports both domain experts as well as non expert users. ©2006 Association for Computing Machinery
