OpenCL requires quite a bit of boilerplate to read and set up platforms, devices, command queues, memory buffers etc.įeel free to browse over the ~100 LoC required for a “Hello world” OpenCL program with Go. The full source can be found here: 2.1 main.go The objective of this blog post is NOT to teach OpenCL, so I’ll keep the sample program as simple as possible, split into two files:
Therefore, I wrote this little blog post if someone else stumbles into the same wall I did. Windows, on the other hand, turned out to be much trickier. On both Macs I tried this with - one with an Nvidida GPU and one with an AMD GPU - compiling with OpenCL support through CGO has worked out of the box. Seems there are a few more recently updated forks, but for my purposes it works alright. I’ve been using jgillich/go-opencl, which seems to be a now abandoned fork of samuel/go-opencl. OpenCL with Golang is based on using some wrapper around the core C library, which requires CGO. However, while developing a new piece of hobbyist software with Go and OpenCL, I found myself in need of running the application on Microsoft Windows 10.
I typically use OS X in my software development endeavours. If you want some tidbits on Golang, OpenCL and CGO on Windows 10 - read on! This is a prelude to an upcoming blog post about Path Tracing with Go and OpenCL, which can be seen as a spiritual sequel to my 2020 ramblings on go ray-tracer optimization.
