Standard Performance Evaluation Corporation
The SPEC ACCELbenchmark tests performance with a suite of computationally intensive parallel applications running under the OpenCL and OpenACC APIs. Support for the OpenMP 4.0 API for Accelerators is expected to be added in a future version of the suite. The benchmark suite exercises the performance of the accelerator, host CPU, memory transfer between host and accelerator, support libraries and drivers, and compilers.
The SPEC ACCEL benchmark is available for purchase via the SPEC order form.
The benchmark suite contains 19 application benchmarks running under OpenCL and 15 under OpenACC. The OpenCL suite is derived from the well-respected Parboil benchmark from the IMPACT Research Group of the University of Illinois at Urbana-Champaign and the Rodinia benchmark from the University of Virginia. The OpenACC suite includes tests from NAS Parallel Benchmarks (NPB), SPEC OMP®2012, and others derived from high-performance computing (HPC) applications.
