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
