Sometime ago, there was a Google Summer of Code project to port NArray to OpenCL
http://www.slideshare.net/scdn/5scdn-ruby-summer-of-code-narray-on-opencl
https://github.com/kazuyukitanimura/narray

There is also this project http://ruby-opencl.rubyforge.org/, if you
want to try multicore acceleration
(as a means to speed up your code) with OpenCL. It should work with
multicore cpus as well as GPUs
