In this paper, we investigate the good parallel computing properties of sparse-grid soluMn techniques. To this end, an existing sequential computational fluid dynamics (CFDl code for a standard :;-D problem from computational aerodynamics is restructured into a parallel appl!cat1L1n. The restructuring is organized according to a master/worker protocol. The coordinator moJulc" developed thereby are implemented in the coordination language MANIFOLD and are lo other problems than the present CFD

The paper contribute~ to the state-of-the-art in improving the efficiency of large-scale computations. We also presen! a theoretical analysis of speed-up through parallelization in a multi-user single-machine envmmment. (0 1998 Elsevier Science B.V. All rights reserved.
