Title: RE-WORKING OF TWO STANDARD MOMENT-METHOD CODES FOR EXECUTION ON PARALLEL PROCESSORS.
Authors: Excell, P. S.1, Porter, G. J.1, Tang, Y. K.1, Yip, K. W.1

Abstract: Two separate exercises on a similar theme are reported. In the first, the moment-method program NEC was extensively modified in order to optimize its performance on a four-processor Cray X-MP computer. In the second exercise, the MININEC moment-method program was completely rewritten into the occam programming language so that it could be executed directly by a transputer system. The NEC exercise exploited judicious use of vectorization and alternative parallelization techniques and achieved a reduction of run times by factors of about five or more. The MININEC exercise has so far achieved only a modest reduction in run-time but it has the potential for a much greater improvement if an optimum strategy for configuring the transputer network is implemented.
