Lighten up, Raul - I didn't make the original comparison - some person at Ohio
State did.

I was correcting my original incorrect correction of *his* comparison in the
above message.

For the record, I believe it is a somewhat silly exercise to compare PCs to
supercomputers, too.  On the other hand, it is interesting to see how large the
span of available computational power remains.

An application?  Not without naming a customer, which I won't do.

However, PERFECT club, SPECmarks, linpack, and many other benchmarks certainly
will, which indicates that many scientific/business applications could.

The ORACLE database runs on PCs, and one of our competition, nCube, is porting
ORACLE to their machine, as reported in the trade press.

This is not true - I am aware of customer codes that run on our machines, which
are supercomputers, and that are also run on minicomputers, workstations, and
PCs, as well.

The supercomputer allows you to handle a larger problem set, perform more
detailed analysis on the data, and/or do the calculations in much less time than
would be required on a smaller/slower machine.

This is why they exist.

But their existance doesn't automatically mean that an application can *only* run
on such a machine, just as the existence of Formula One race cars does not preclude the use of a Hyundai for commuting.

Nice strawman.  Because you can't imagine an application that spans three or four
orders of magnitude in performance requirements, it must not exist.

Business applications use supercomputers routinely today, and have for at least a
decade.

*Serious* researchers use supercomputers, and have for at least three decades. 
Workstations are for software development, reading netnews, and running X and
EMACS. :^)

[Ever known any *goofy* researchers?]
