Not on Linux. Intel only supports using OpenCL on the Xeon Phi coprocessors if you're using Linux.
Iris OpenCL support is restricted to Windows.
- galaktor 13y agowell that sucks. I'm curious, is that a driver limitation? how do they restrict it from working in linux?
- hdevalence 13y agoIntel simply doesn't provide an OpenCL implementation on Linux, and there's no free one (as yet, and for the future). OpenCL support on Linux is an unmitigated disaster; I worked with it this summer in a different KDE program. I wouldn't get your hopes up.
- galaktor 13y agoafter reading around a bit [1], I get the impression that while the situation isn't great, it isn't a hopeless disaster, either. Apparently there's Linux drivers but only x64, and not in a Ubuntu-friendly format. Hopefully this will change. I'll play around with it a bit, to see how bad it really is first hand :-) thanks [1] http://mhr3.blogspot.ie/2013/06/opencl-on-ubuntu-1304.html http://mhr3.blogspot.ie/2013/06/opencl-on-ubuntu-1304.html Edit: apparently the drivers that are available for Linux don't support HD or Iris GPUs.
