OpenMP Validation and Verification Testsuite

This open-source suite comprises functional/unit tests that help explore the implementation progress of various OpenMP offloading compilers for OpenMP 4.5 and onwards. The suite also tests for conformance of feature implementations to the standard specification.

OpenMP vs Offload

OpenMP vs Offload (OvO) is a collection of OpenMP standard-compliance tests developed at Argonne National Lab for target offloading in C++ and Fortran. It focuses on hierarchical parallelism and mathematical functions.

SPEC ACCEL

This benchmark suite tests performance with computationally intensive parallel applications running under the OpenCL, OpenACC, and OpenMP 4 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.

SPEC HPC Benchmark Suite

This suite 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. Includes several OpenMP codes and published online results.
