Adapting a Navier-Stokes Code to the ICL-DAP

Abstract

This is a report of the results of an experiment:to adapt a NavierStokes code, originally developed on a serial computer, to concurrent processing on the ICL Distributed A__rrayP__rocessor (DAP). In this paper the algorithm used in solving the Navier-Stokes equations is briefly described.The architecture of the DAP and DAP Fortran is also described. The modifications of the algorithm so as to fit the DAP are given and discussed.Finally, performance results are given and conclusions are drawn.

Optimization techniques for SIMD Fortran compilers

“…The algorithm for the program was first discussed in Reference 23 and adapted to the ICL DAP by Grosch [24]. Implementations of the method for the MpP, the FLEX/32 and the CRAY/2 wete developed and studied by This is less than 12% of the time for i n t e r p m r communication in the canonical version.…”

“…We obtained a program implementing a fouralor relaxation scheme in connection with a study done for a customer. The algorithm for the program was first discussed in Reference 23 and adapted to the ICL DAP by Grosch [24]. Implementations of the method for the MpP, the FLEX/32 and the CRAY/2 wete developed and studied by Fatoohi and Grosch and reported on in the proceedings of the 1987 International Conference on Parallel F'rocasing [25].…”
