To be fair, you original comment did use both "supercomputer" and "HPC". I'd argue that, although in most people's minds, the two are indistinguishable (perhaps like the words "envious" and "jealous"), but carry a unique significance to practitioners. That said, any lay definition of supercomputer would seem to require actual performance (e.g. high FLOPS rate), which trivally supports the initial assertion. One can call something like the Folding@Home project a distributed supercomputer, but it's not that interesting, especially to build such a system, for anything embarrassingly parallel.
