This code base contains the code to run OpenCL programs on<o:p></o:p> Intel GPUs which basically defines and implements the OpenCL host functions<o:p></o:p> required to initialize the device, create the command queues, the kernels and<o:p></o:p> the programs and run them on the GPU. The code base also contains the compiler<o:p></o:p> part of the stack which is included in `backend/`. For more specific information<o:p></o:p> about the compiler, please refer to `backend/README.md`<o:p></o:p> <o:p> </o:p> Visit wiki: <a href="http://wiki.freedesktop.org/www/Software/Beignet/">
