OpenCL On Linux Is Still Not Too Easy, Widespread
Written by Michael Larabel in Free Software on 2 June 2013 at 05:24 PM EDT. 10 Comments
While there's OpenCL drivers available for Linux, on Ubuntu there is no OpenCL driver shipped by default and the proprietary driver implementations aren't always great.

Intel has their closed-source OpenCL SDK for the CPU, AMD has their OpenCL support in the Catalyst driver, and NVIDIA has their OpenCL/CUDA support bundled within their binary driver. When it comes to open-source support, the Gallium3D OpenCL support is still primitive and isn't shipped by default. Intel has the Beignet project for open-source OpenCL but that's even worse off than the Gallium3D OpenCL support.

For details on the experiences of using OpenCL on Ubuntu 13.04 and other information, an open-source developer, Michal Hruby, has written about it on his blog.
