DescriptionThe High-Performance Group (HPG) of the Standard Performance Evaluation Corporation (SPEC) is a forum for discussing and developing benchmark methodologies for High-Performance Computing (HPC) systems. The group released the SPEC ACCEL benchmark in 2014, containing OpenCL and OpenACC components. In 2017, an OpenMP 4.5 target offload component was added by porting the OpenACC applications to OpenMP 4.5. This talk will introduce the benchmark, show results and talk about the lessons learned from developing and maintaining this directive based benchmark. In addition, current challenges of creating a follow on suite are discussed.
