The SPEChpc® 2002 benchmark is derived from real HPC applications and application practices, and measure the overall performance of high-end computer systems, including the computer's processors (CPUs), the interconnection system (shared or distributed memory), the compilers, the MPI and/or OpenMP parallel library implementation, and the input/output system.

Benchmark retirement - Benchmark results are no longer being accepted for publication on SPEC's site. Sales of the software were discontinued in February 2007, and technical support is no longer provided.

The SPEChpc®2002 Benchmarks

The benchmarks which make up the suite are:

  • The SPECCHEM® 2002 benchmark, which is based on a quantum chemistry application called GAMESS and includes the SPECchemM 2002 performance metric and the SPECchemS 2002 performance metrric.

  • SPECENV® 2002 benchmark, which is based on a weather research and forecasting model called WRF. It includes the SPECenvM 2002 performance metric and the SPECenvS 2002 performance metric, one for each dataset size.

  • The SPECSEIS® 2002 benchmark, which represents an industrial application that performs time and depth migrations used to locate gas and oil deposits and includes the SPECseisM 2002 performance metric and the SPECseisS 2002 performance metric.

Each of the three benchmarks has both Small and Medium workloads available.

Benchmark Features:

  • Code is selected from full HPC applications
  • Parallelism supported: serial, OpenMP, MPI, or combined MPI-OpenMP
  • Architectures supported: shared memory, distributed memory, clusters
  • IO and communication included in the benchmarks
  • Run rules tailored to HPC application environments
  • Implemented under SPEC tools for building applications, running with different data sets, verifying results and measuring runtime.
