Abstract | The motivation behind the development of the GENESIS benchmark suite has been to assemble benchmarks for a range of important scientific and engineering problems, which require high performance computing. The suite is being used to evaluate the relative strengths and weaknesses of current distributed-memory (DM) machines and to enable predictions of performance on future parallel computer architectures. In this paper the current release of the GENESIS benchmarks is first presented. Both message-passing and subset HPF versions exist for most of the codes in addition to the standard Fortran77 versions, with the PARMACS macros being used to express the necessary extensions to Fortran77 for task creation and message passing in the distributed versions, and for conferring portability across target systems. Some recent results from selected benchmarks running on the Intel iPSC/860 and the Meiko i860 Computing Surface are finally described and related to basic system parameters. |
