Intel GPU is Useless for OpenCL on Linux
You can use OpenCL on your Intel based linux machine, but buried in the fine print you will find that it only runs on the CPU, those 300 million transistors and 25% of your processor die area in your GPU are completely useless.
I feel a little silly for making sure my servers had HD4000 GPUs in case the day came when I needed an OpenCL boost. The day came. I’m not getting it.
