 * In order to take advantage of OpenCL you will need a runtime for your hardware.
 * Currently included in Gentoo are:
 * 
 *  * open:
 *     - dev-libs/intel-compute-runtime - integrated Intel GPUs from Broadwell onwards. 64-bit only;
 *     - dev-libs/pocl - to run OpenCL programs on your CPU, if you do not have a supported GPU;
 *     - dev-libs/rocm-opencl-runtime - AMD GPUs supported by the amdgpu kernel driver. 64-bit only;
 *     - media-libs/mesa[opencl] - some older AMD GPUs; see [1]. 32-bit support;
 * 
 *  * proprietary:
 *     - dev-libs/amdgpu-pro-opencl - AMD Polaris GPUs. 32-bit support;
 *     - dev-util/intel-ocl-sdk - Intel CPUs (*not* GPUs). 64-bit only;
 *     - x11-drivers/nvidia-drivers - Nvidia GPUs; specific package versions
 *       required for older devices [2]. 32-bit support.
