SPEC High-Performance Groupwww.spec.org/hpg zFounded in 1994 zMission: To establish, maintain, and endorse a suite of benchmarks that are representative of real-world high- performance computing applications. zSPEC/HPG includes members from both industry and academia. zBenchmark products, SPEC OMP (OMPM2001, OMPL2001), SPEC HPC2002 new release at SC 2002, replaces SPEChpc96 first results have just been released generated!

SPEC HPC2002 Includes three (suites of) codes zSPECseis, used in the search for oil and gas zSPECchem, used in chemical and pharmaceutical industries (gamess) zSPECenv, weather forecast application (WRF) All codes include several data sets and are available in a serial and a parallel variant ( MPI, OpenMP, hybrid execution is possible ).

SPEC HPC Benchmarks: Whats Really New? zSPEC HPC2002 has been developed with the involvement of most major computer manufacturers we have broad support zAs a result, the portability of the benchmarks has improved drastically y running SPEC HPC2002 is easy … y… but still hard enough that a machine with a good environment wins!

Where is SPEC HPC Relative to Other Benchmarks There are many metrics, each one has its purpose Raw machine performance: Tflops Kernel benchmarks: Linpack Compact Applications: NAS benchmarks Largest public applications: SPEC HPC User-specific applications: Custom benchmarks
