In order to use CPU devices, you need -D 1. In order to use CPU+GPU, you need to use -D 1,2 instead. Do not use -d in this case because you would enable opencl runtimes for the same device but with less dedicated instruction support. It's unclear if -D 1,2 works faster in non-brute force mode because of the 100% cpu bug on NV.
