- it is my first Ruby C extension ever
- it is my first OpenCL approach ever
- it is my first MacRuby hack (ever)
With this in mind, don’t expect real world usage from this code, nor that it will get merged into upstream: it was just written for fun!
The MacRuby branch with the changes is located here
The hello world on OpenCL is probably “calculate each element’s square on a given array”. The code below shows how this can be done in MacRuby:
This code runs the same computation on all available OpenCL devices on your hardware. The results on my hardware (2 GPUs, 1CPU) are:
It was fun, and maybe it can inspire someone :) The OpenCL API is kinda complex and I’m not sure if there’s a good way of making it Rubyish enough. Suggestions are welcome! Have fun :)
