Abstract. We present a new benchmark suite for parallel computers. SPEComp targets mid-size parallel servers. It includes a number of science/engineering and data processing applications. Parallelism is expressed in the OpenMP API. The suite includes two data sets, Medium and Large, of approximately 1.6 and 4 GB in size. Our overview also describes the organization developing SPEComp, issues in creating OpenMP parallel benchmarks, the benchmarking methodology underlying SPEComp, and basic performance characteristics.
arallel application developers today face the problem of how to integrate the dominant parallel processing models into one source code. Most high-performance systems use the Distributed Memory Parallel (DMP) and Shared Memory Parallel (SMP; also known as Symmetric MultiProcessor) models, and many applications can benefit from support for multiple parallelism modes. Here we show how to integrate both modes into high-performance parallel applications. These applications have three primary goals:
Abstract-In this paper, we discuss results and characteristics of the benchmark suites maintained by the Standard Performance Evaluation Corporation's (SPEC) High-Performance Group (HPG). Currently, SPEC HPG has two lines of benchmark suites for measuring performance of large-scale systems: SPEC OMP and SPEC HPC2002. SPEC OMP uses the OpenMP API and includes benchmark suites intended for measuring performance of modern shared memory parallel systems. SPEC HPC2002 uses both OpenMP and MPI, and thus it is suitable for distributed memory systems, shared memory systems, and hybrid systems. SPEC HPC2002 contains benchmarks from three popular application areas, Chemistry, Seismic, and Weather Forecasting. Each of the three benchmarks in HPC2002 has a small and a medium data set, in order to satisfy the need for benchmarking a wide range of high-performance systems. We analyze published results of these benchmark suites regarding scalability. We also present current efforts of SPEC HPG to create new releases of the benchmark suites.
