To make use of CUDA, you need a computer with a GPU made by NVIDIA. Unfortunately, setting up CUDA to work with Gorgonia is a slightly more involved process, as it involves setting up a C compiler environment to work with Go, as well as a C compiler environment that works with CUDA. NVIDIA has kindly ensured that its compiler works with the common toolchain for each platform: Visual Studio on Windows, Clang-LLVM on macOS, and GCC on Linux.

Installing CUDA and ensuring that everything works correctly requires a fair bit of work. We'll look at doing this for Windows and Linux. As Apple has not made a computer featuring an NVIDIA GPU for several years (as of writing this), we will not cover how to do this on macOS. You can still use CUDA by connecting an external GPU to your macOS, but this is a fairly involved process and Apple does not (as of writing this) have an officially supported setup with an NVIDIA GPU.
