heal.abstract	Parallel processing over the Internet is now becoming a realistic possibility. There are numerous of-the-shelf-high-performance computing (HPC) platforms available with Internet access, on which to implement computationally intensive algorithms. HPC can be applied in the field of computational electromagnetics, to investigate problems that were so computationally expensive that they were practically "unsolvable." The networking capabilities of the Internet now allow these computing resources to be used as a remote service. Additionally, the pragmatics of their utilization can be abstracted by adopting a World Wide Web (WWW) interface. A Web-based environment can provide the supportive tools for data entry, program initiation, result visualization, and even interactive modifications of the geometry and/or the electromagnetic (EM) properties of the problem being examined. For realistic interaction, the emerging question is which algorithm to use that supports the exploitation of parallelism. The rapid porting and evolution of algorithms originally designed for sequential machines to current HPC platforms, is now beginning to reach the limit of performance, as predicted and defined by Amdhl's law. The available HPC-platform performance now vastly exceeds the expectations imposed by these algorithms. In order to exploit and utilize all the available performance of current and predicted HPC platforms, inherently-parallel-based algorithms have to be devised. One such algorithm is the Parallel Method of Moments/Method of Auxiliary Sources, P(MoM/MAS), introduced in this paper. The resulting algorithm parallelization enables the MoM/MAS method to be applied to solving electrically-large-in-size and complex EM structures on various computational platforms. This paper concentrates on the parallel-processing issues, and on the importance of adopting suitable algorithms, such as the MoM/MAS technique. However, the authors would still like to draw the readers' attention to the potential possibilities of using the WWW as the interface environment, not only for connectivity, but also for three-dimensional and even four-dimensional visualizations. These can be presented through a standard WWW browser, independently of the underlying architecture.	en
