go-opencl is a wrapper around the C OpenCL 1.2 API for Go. It aims to be close to the C API while adding Go features (object orientation, []string instead of space delimited extension list, etc.).
It is mainly developed and tested on Linux and with Intel and Nvidia GPUs. It should work with AMD GPUs and, at least in theory, it should work on Windows and macOS.

There isn't too much documentation in this project, however the API mimics the C API (with some object orientation thrown in), so by taking a look at the official OpenCL 1.2 documentation it should be easy enough to understand. Take a look at the included go-opencl-info utility to see how to use this API.
