I see two paths that can get us there:
(1) dynamic partitioning of the flow graph across processors in
SMP/multi-core machines.
(2) m-blocks dynamically scheduled across processors on SMP/multi-core
Once N-cores gets sufficiently large (8 ?), I think we start moving to
a thread / block model.

Or perhaps Express Card. That would retain the laptop's portability advantage.
