SPECaccel ® 2023

The SPECaccel® 2023 benchmark suite tests performance with computationally intensive parallel applications running under the OpenACC and OpenMP target offloading APIs. The suite exercises the performance of the accelerator, host CPU, memory transfer between host and accelerator, support libraries and drivers, and compilers.

Benchmark tests

The benchmark suite uses many of the original benchmarks from SPEC ACCEL V1.4 with increased workload sizes and runtime to better measure modern accelerators. It contains 12 application benchmarks ported to use either OpenACC, OpenMP using "loop" constructs, OpenMP with "distribute" constructs favoring collapsing all loop levels, and OpenMP with "distribute" applied to outer loops and "simd" applied to inner loops. The choice of model is selected by the user based on the compiler and accelerator they are using. Models may be mixed in peak results.

SPECaccel 2023 includes benchmarks from NAS Parallel Benchmarks (NPB), SPEC OMPĀ® 2012, Parboil benchmark from the IMPACT Research Group of the University of Illinois at Urbana-Champaign and others derived from high-performance computing (HPC) applications.
