Parallel computing for RF scattering calculations

Three-dimensional RF scattering calculations for objects of realistic complexity, which require parallel computational methods in order to be feasible for design tradeoff studies, are discussed. Two basic approaches to obtaining parallel speed improvements are vectorization and full parallel processing. In the latter category are shared-memory and distributed-memory multiprocessor machines. The approaches to parallel computation are reviewed, and the changes required to adapt RF scattering analysis to each major parallel architecture are considered. A comparison of conversion effort and execution performance is presented for representative computers.<
