The task of calculating the lowest few eigenvalues and eigenvectors of Maxwell's equations for a resonating cavity of moderately complicated shape easily exhausts the capacity of present-day computers. Massively parallel MIMD-systems would provide the necessary memory size and computing power, but the problems of implementing the algorithms are not solved yet. The present paper studies some ways of partitioning the computation for an existing software package and evaluates the resulting requirements for memory size, communication capabilities and computing power. It turns out that for realistic communication networks the minimal size of a subtask that can efficiently be treated by one processor is quite large, thus placing a limit to the reasonable amount of parallelism for a given problem size. |
