We announced the first OpenCL SDK for x86 CPUs as part of the Stream 2.0 Beta. Runs on both Windows and Linux, with OpenSUSE 11.0 and Ubuntu 8.04 being the recommended platforms for now.
The Stream 2.0 Beta page with download links is at : http://developer.amd.com/GPU/ATISTRE...s/default.aspx
... and press releases, blog posts etc... are here : http://www.amd.com/us/press-releases...2009aug04.aspx
