3D Navier-Stokes Flow Analysis for Shared and Distributed Memory MIMD Computers

Parallel, Shared Memory, Distributed Memory 9. ABSTRACT (Continue on reverse of necessary and Wentify by block number) Multiple instruction multiple data (MIMD) parallel computers were investigated as a means of obtainng the immense computer power required to analyze the flow about a complete aircraft configuration. A computational fluid dynamics computer program for solving the Navier-Stokes equations, with coupled nonequilibrium chemistry, was parallelized on three MIMD computer: the Intel Touchstone distributed memory computer, the Cray Y/MP super-computer, and the Silicon Graphics IRIS 4-D/38() shared memory computer. The program used an LU-SGS implicit algorithm. The parallelizat:ion was performed using permanent domain decomposition. The parallel efficiency and the main limitations to efficient parallelization were evaluated for a series of real life engineering problems. On th
