Abstract
In this article we discuss the detailed implementation of a parallel pseudospectral code for integration of the Navier-Stokes equations on an Intel iPSC/860 Hypercube. Issues related to the basic efficient parallelization of the algorithm on a hypercube are discussed, as well as optimization issues specific to the iPSC/860 system. With the combination of optimizations presented, the code runs on a 32-node iPSC/860 system at a speed exceeding that of the fastest implementation on a Cray YMP by nearly 25%.
