Abstract

This paper describes a performance evaluation study of Ex-press programming environment on the iPSC1860 hypercube com-puter. Express allows parallel programs to be developed in a com-pletely portable fashion and is available on most commercially available parallel computers as well as networks of workstations. We have developed a set of benchmarks to make a comprehensive performance assessment of the frequently used communication primitives of Express on hypercube computers. A comparison with the equivalent iPSCI860 primitives is also carried out. In ad-dition, we have developed and benchmarked a suite of applica-tions including three different versions of Gaussian elimination, fast Fourier transform, and the N-body problem. These results help us evaluate the performance of Express and judge its merits against the extra overhead incurred due to portability, and can be useful for designing new generations of portable programming en-vironments. Furthermore, algorithm developers can benefit from these results by using the times required by the basic communica-tion primitives on the iPSC1860 system with and without Express, and can automate performance estimation by using these timings. 1
