GPU-STREAM
Measure memory transfer rates to/from global device memory on GPUs. This benchmark is similar in spirit, and based on, the STREAM benchmark [1] for CPUs.
Unlike other GPU memory bandwidth benchmarks this does not include the PCIe transfer time.
Usage
Build the OpenCL and CUDA binaries with make
Run the OpenCL version with ./gpu-stream-ocl and the CUDA version with ./gpu-stream-cuda
