| Abstract | Abstract This paper describes the performance evaluation of Express programming environment on the iPSC/2 and iPSC/860 hypercube computers. Express allows parallel programs to be developed in a completely 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 iPSC/2 and iPSC/860 primitives is also carried out. In addition, we have developed and benchmarked a suite of real applications 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. The results also enable us to make a comparison of two generations of hypercube systems. Furthermore, algorithm developers can benefit from these results by using the times required by the basic communication primitives on both hypercubes with and without Express, and can automate performance estimation by using these timings. |
