My reason for asking.

I think it would be cool if maybe the kernel+OS+DE(Unity) always ran off the tablet and when docked applications would run on the x86 and discrete graphics. I know I've seen tablets go from integrated to discrete graphics when docked. I also know there are distros that can do parallel computing with Beowulf clusters.

My first question: If it were two x86 or two ARM processers, could the work be divided where only applications ran on the second, with everything else running on the first?

Second question: If the above scenario is possible, would it be feasible when pairing the differing architectures?
