This is another completely baffling aspect of Radeon drivers:
OpenCL SDK will not install CPU components if Catalyst is already installed.
I have to have Catalyst and the SDK installed if I want to run OpenCL apps on my Radeon.
So, how can I run OpenCL apps on my AMD CPU if I also have a Radeon GPU?
(In a related question, why does clinfo find CPU and GPU resources, even though the SDK is not installed and other applications *cannot* find OpenCL resources? If clinfo doesn't identify fully functioning OpenCL resources, what command actually tells me when OpenCL is functional?)
