Technically all because we can generate candidates on a cpu and send
them to the gpu to calculate.
It is ok for slow formats but things like raw-* suffer from PCIe
performance bottleneck..
We had some improvements to the mask mode to generate candidates on a
gpu, but I am not sure about its current state.

Thanks,
