                  An OpenCL device that is the host processor. The host processor
                  runs the OpenCL implementations and is a single or multi-core CPU.

                  An OpenCL device that is a GPU. By this we mean that the device
                  can also be used to accelerate a 3D API such as OpenGL or DirectX.

                  Dedicated OpenCL accelerators (for example the IBM CELL Blade). These
                  devices communicate with the host processor using a peripheral
                  interconnect such as PCIe.
