I've read somewhere that next generation of Nvidia gpus code named maxwell
will tightly integrate some ARM cores with them. I guess then we could use
the gpus for efficient password generation too.  Also AMD's next generation
of APUs(excavator or later) intends to do the same with x86 instead of

Accorinding to the picture(in your slides) the xeon phies seems to be
running on a PCIe bus. But if it can load an OS then does it mean we can
use the phi as the host system and the cpu/gpus as the supporting devices?
