It is defined to & for CPU side compilation, and defined to an empty for any GPU platform. The idea here is to use this macro instead of #ifdef block with bunch of duplicated lines just to make it so CPU code is efficient. Eventually we might switch to references on CUDA as well, but that would require some intensive testing.
