46 17th TOP500 list to be published at SC2001 in Heidelberg we are just finalizing the work with the 17th list here are some speculations about the new list: - we expect again IBM to dominate the list as far as the number of systems is concerned and as a performance leader - we believe that the Supercomputer System NEC SX5/128 M8 at Osaka University will make the TOP10 of the new list exceeding 1 Tflop/s R max performance - we expect an entry level performance for the new list lower than 70 Gflop/s

51 Problems with LINPACK Commercial DB systems don t care about floating point New architectures - compute farms not designed to run LINPACK Self-made cluster no vendor to measure LINPACK every system is different

52 TOP500 Plans Talks with experts since 3 years on how to resolve these issues Q: How can we provide better information for different application and architecture domains? A: Make additional lists

53 TOP500 Plans Collaborate with research centers (NERSC, ICL,...) which develop new benchmarks Feedback about benchmarks TOP500.org will provide free access to benchmark results and possibilities for re-ranking
