In this chapter, we learned how to speed certain computations in R by leveraging GPUs. Given that most computers today come with a GPU, this gives a quick opportunity to improve the performance of R programs. This is especially true with the growing number of packages that interface R with GPUs. Some, such as gputools, require no knowledge of CUDA or OpenCL at all. GPUs do not guarantee improved performance for all tasks.
In the next chapter, we will turn our attention to address RAM-related issues in R programs.
