Notes:
Electromagnetic and acoustic scattering from bodies many wavelengths long presents some of the largest computational problems, with costs scaling with the fourth to sixth power of incident frequency. Parallel processing offers one contributory route to the increase in computational power required for such analyses. The paper presents a parallel implementation of the integral formulation of the transient wave equation. It is demonstrated that it is the repeated evaluation of far field effects which is the dominant cost, and that with appropriate domain partitioning this process can be parallelised very effectively. Results for scattering problems comprising up to 1658 nodes are presented, evaluated on 64- and 128-processor systems.
