Re: Intel HD Graphics

Intel doesn't provide any OpenCL SDK. There is no way to "program" the GPU.

That's untrue, starting with sandy bridge and up Intel's IGP supports OpenCL.
Their SDK can be downloaded from here:
http://software.intel.com/en-us/articles/vcsource-tools-opencl-sdk/

Cant DL right now, but will definitively look at it tomorrow and possible slap something together even if its shit .
