SPEC High-Performance Group www.spec.org/hpg
  • Founded in 1994
  • Mission To establish, maintain, and endorse a
    suite of benchmarks that are representative of
    real-world high-performance computing
    applications.
  • SPEC/HPG includes members from both industry and
    academia.
  • Benchmark 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
  • SPECseis, used in the search for oil and gas
  • SPECchem, used in chemical and pharmaceutical
    industries (gamess)
  • SPECenv, 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 BenchmarksWhats Really New?
  • SPEC HPC2002 has been developed with the
    involvement of most major computer manufacturers
    ? we have broad support
  • As a result, the portability of the benchmarks
    has improved drastically
  • running SPEC HPC2002 is easy
  • but still hard enough that a machine with a
    good environment wins!

5
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
