We know that getting full computational performance out of most machines—nearly all desktops and laptops, most game consoles, and the newest smartphones—already means harnessing local parallel hardware, mainly in the form of multicore CPU processing. This is the commoditization of the supercomputer.

Take a trivial example with three components A, B, and C. Now you might say that the system is designed such that A only talks to B, and B only talks to C. But do A and C share the same storage, compute, or network resources for example? In a fast changing world, the effort needed to keep up to date can be daunting.
