I disagree.

Any definition of "HPC" must address capability, not merely saturation
of resources.

An HPC system must be capable of doing something challenging for non-HPC
systems.  Granted, this amounts to "grading on the curve" - or perhaps as
for pornography, it could said that we know it when we see it. :)
