The Current Open-Source OpenCL Experience On Fedora

With the open-source OpenCL news this week about Beignet working on OpenCL 2.0 support and Intel Cherryview now supporting OpenCL, I decided to see how the open-source OpenCL support is shaping up for the soon-to-be-released Fedora 22.

Beignet and friends aren't installed by default, but can be easily fetched through the Fedora repositories. Clinfo is another great package to install for new OpenCL Linux users to find out all of your OpenCL details.

Beignet 1.0.1 was in the F22 repository during testing to provide OpenCL 1.2 support for my Intel Haswell graphics processor. Beignet works out great even though it's not part of Mesa -- the Gallium3D Clover still is at CL 1.1, etc. Intel has several engineers working seemingly full-time on this open-source OpenCL stack.

Sadly though, the interesting OpenCL benchmarks like LuxMark weren't working on the Beignet 1.0.1 stack at this time as the program would crash while compiling the compute kernels.

POCL, the Portable Computing Language, is an interesting open-source project if seeking to get OpenCL on CPUs. POCL 0.10 provided OpenCL 1.2 to the Intel Haswell CPU on the test system I was toying with. However, it too still isn't along quite enough to get the new LuxMark CL benchmark and such up and running on it.
