The workways problem solving environment

Science gateways allow computational scientists to interact with a complex mix of mathematical models, software tools and techniques, and high performance computers. Accordingly, various groups have built high-level problem-solving environments that allow these to be mixed freely. In this paper, we introduce an interactive workflow-based science gateway, called WorkWays. WorkWays integrates different domain specific tools, and at the same time is flexible enough to support user input, so that users can monitor and steer simulations as they execute. A benchmark design experiment is used to demonstrate WorkWays. © The Authors. Published by Elsevier B.V
