The genesis distributed-memory benchmarks represent a significant step forward in the evaluation of distributed-memory MIMD systems. The initial version of this benchmark suite was augmented and modified in order to evaluate the suprenum computer. This augmented suite has now been further modified to allow the benchmarks to be run on several important distributed systems without further code modification. This paper briefly describes the benchmark suite and outlines the methodology employed to run the benchmarks and interpret timing measurements. Some preliminary results from selected benchmarks running on the Intel ipsc/860 and the Meiko i860 Computing Surface are described and related to basic system parameters. The paper concludes with the possible future evolution of the suite
