Intel Broadwell OpenCL Support Comes To Beignet
Written by Michael Larabel in Intel on 12 October 2014 at 06:17 PM EDT. 2 Comments
Intel OpenCL Linux compute support has landed for the forthcoming Broadwell processors.

Pushed this week by Yang Rong and other Intel OTC China staff was the initial Broadwell hardware enablement in Beignet, the Intel OpenCL Linux implementation. Beignet has been building up since the Ivy Bridge days and now in time for the debut of the first ultrabooks with Broadwell designs is the necessary GPGPU compute support.

Nothing too interesting right now without the hardware in hand but you can find the commits in Git. The Intel Broadwell OpenCL Linux support should be found with the prospected Beignet 1.0 release. Of course, for the Broadwell graphics side that's already been baking into the Linux kernel and Mesa for several release cycles.

The latest ID information for Intel Broadwell CPUs come down to:
