Used to set or switch between OpenCL devices.

Parameters

aDeviceId	the id of the opencl device of type cl_device_id, "" means use software calculation
bAutoSelect	use the algorithm to select the best OpenCL device
rOutSelectedDeviceVersionIDString	returns the selected device's version string.

Returns

returns true if there is a valid opencl device that has been set up
