In this report we document an attempt to make it easier to use powerful GPUs by extending the Scala compiler to automatically offload work to the GPU. We benchmark similar code and find that it provides between 2-3 speedup compared to the CPU alone. Finally we discuss ways to improve the extention to offload more work.
