The use of supercomputing technology, parallel and distributed processing, and sophisticated algorithms is of major importance for computational scientists. Yet, the scientists' goals are to solve their challenging scientific problems, not the software engineering tasks associated with it. For that reason, computational science and engineering must be able to rely on dedicated support from program development and analysis tools. The primary intention of this workshop is to bring together developers of tools for scientific computing and their potential users. Tool developers present how their tools support scientists and engineers during program development and analysis. The users report their experiences employing such tools, especially highlighting the benefits and possible improvements. (C) 2010 Published by Elsevier Ltd.
