| Abstract: | Computing systems of the future for large-scale scientific and engineering computations will consist of many processors and memories working in parallel to solve a single problem. Efficient use and ease of use of these future systems are two basic problems facing potential users. The development of new parallel algorithms and parallel programming environments is essential for progress toward the solution of these problems. In this paper we develop parallel algorithms for a class of scientific computational problems by partitioning the problems into smaller problems which may be solved concurrently. The effectiveness of the resulting parallel solutions are determined by the amount and frequency of communication and synchronization and the extent to which communication can be overlapped with computation. We present three different parallel algorithms for solving the same class of problems and analyze their effectiveness from this point of view. The algorithms are programmed using a flew programming environment. Run-time statistics and experience obtained from the execution of these programs assist in measuring the effectiveness of these algorithms. [ABSTRACT FROM AUTHOR] |
