<p>One of the crucial aspects in the design process of high voltage apparatus is the precise simulation of the electrostatic and/or electromagnetic field distribution in three dimensional domains. Since these simulations are rather computing- and communication-intensive, the solvers for both electrostatic and electromagnetic computations need to be parallelized. For this kind of code, clusters of commodity PCs, with or without high-speed interconnection technologies, are becoming increasingly important as target platforms, due to their excellent cost-performance ratio.</p> <p>This paper summarizes the results that were obtained on such a cluster platform installed at ABB Corporate Research using POLOPT, a state-of-the-art parallel simulation environment for both electrostatic and electromagnetic problems. The experiments where conducted on a LINUX cluster using both Ethernet- and SCI-based interconnection technologies to allow a study of the impact of high-speed networking technology. For both electrostatic and electromagnetic field simulations in practical High Voltage Engineering, a high efficiency was obtained in this commodity environment. In addition, the results have shown that some codes, in this case the electromagnetic solver, are highly sensitive to the communication performance and hence can significantly benefit from the presence of fast interconnection mechanisms, as given with SCI.</p>
