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

Results

Sample results can be found in the results subdirectory. If you would like to submit updated results, please submit a Pull Request.
