Abstract
The Langley Aerothermodynamic Upwind Relaxation Algorithm (LAURA), a N avier-Stokes solver, has been modified for use in a parallel, distribu ted-memory environment using the Message-Passing Interface (MPI) stand ard. A standard domain decomposition strategy is used in which the com putational domain is divided into subdomains with each subdomain assig ned to a processor. Performance is examined on dedicated parallel mach ines and a network of desktop workstations. The effect of domain decom position and frequency of boundary updates on performance and converge nce is also examined for several realistic configurations and conditio ns typical of large-scale computational fluid dynamic analysis.
