If you wanted this discussion to end, why are you continuing it?

Gordon Bell asked (about huge computers) in a presentation now 12 years old:
"Is it worth it?"

If you're not going to get new science out of a huge new computer, then why
spend the money?

I have one answer to where there is possibly new science, but we never get
the computer to explore it.

"My" problem domain (fluid mechanics) is a big driver behind the huge
expenditures on "supercomputers," which as I have pointed out ad nauseum,
are far from super in some really important ways.

The GPU may be a very handy tool for certain kinds of computations, but it
almost inherently replicates a design corner-cutting that that is endemic in
supercomputing right now (low bytes per flop).

If you want to say, "GPGPU's will help *my* problem, so I want one," I have
no answer for that.

If you propose that the GPU is an ideal tool for university level teaching
and research that requires hefty computing, as the poster I responded to
did, then I have some serious objections based on good science.

I presented my position, I defended my reputation and my position against
wild and ignorant slurs, and you have now joined a chorus that wants to
comment on my personality, rather than on anything technical.  Perhaps you
are the one who should stop harping?
