Mixbench

The purpose of this benchmark tool is to evaluate performance bounds of GPUs
(or CPUs) on mixed operational intensity kernels. The executed kernel is
customized on a range of different operational intensity values. Modern GPUs
are able to hide memory latency by switching execution to threads able to
perform compute operations. Using this tool one can assess the practical
optimum balance in both types of operations for a compute device. CUDA, HIP,
OpenCL and SYCL implementations have been developed, targeting GPUs, or
OpenMP when using a CPU as a target.
