This paper describes the development and performance of an accurate computational algorithm to simulate unsteady flows in rectangular geometries on the massively parallel computer, CM-5. The time-dependent Navier-Stokes equations have been discretized using a fully-explicit second-order time splitting scheme and high-order spatial differencing. The algorithm has been programmed in CM FORTRAN and implemented on the CM-5 in the Single-Instruction, Multiple-Data (SIMD) mode. The performance of the algorithm is described in the context of two and three-dimensional numerical simulations of the driven cavity and the wake of a flat plate held normal to a free stream.
