CODES (Computing on Demand for Electromagnetic Software and applications) is a cooperative research project, part of the European FP6 call, intended to research ways to boost the performance of existing electromagnetic design tools. Today, the marketing success of these products is strongly dependent on the computational speed of the software. And Grid computational technology offers a robust and seamless environment to achieve high speed performance. GridSystems is a major player in setting up the Grid test and development environment, and in the dissemination and exploitation phase of the project.
