✦ Synopsis

With the development of concurrent computing architectures which promise cost-effective means of obtaining supercomputing performance, there is much interest in applying and in evaluating the actual performance on large, computationally-intensive problems. Of particular interest is the concurrent performance of large scale electromagnetic scattering problems. Two electromagneticcodes with differing underlying algorithms have been converted to run on the Mark III Hypercube. One is a time domain finite difference solution of Maxwell's equations to solve for scattered fields and the other is a frequency domain moment method solution.

Important measures for demonstrating the utility of the parallel architecture are the size of the problem that can be solved and the efficiency by which the paralleling can increase the speed of execution.
