For the entire top 500 they are running a Unix variant or a linux variant.
Linux "owns" the list with Unix claiming just 92 out of the 500 machines,
Mac OS X on three of them and not a single one running any M$ OS. This
includes Japan's earth simulator, a vector machine (now ranked 14). IBM
and HP are the top hardware vendors. Some interesting surprises for me.

Interesting yes, but what does it prove? That's like going to a large
parking lot and saying oh look, none of these 500 cars run on
kerosene. Well duh, no. Not designed to. You would think if they can
afford to buy a super computer they could afford a custom OS designed
for the super computer. Maybe there isn't such a thing.

What does this have to do with installing Vista?

I am not surprised. Linux has been a big player in supercomputing few
several years now and ISTR the THE fastest supercomputer runs Linux.

Neither am I surprised MS figures nowhere, they only make toy OSs.

If you can't see the relavance of this statement then you're not too bright.

Well a unix or a linux is an open source system that
is adaptable for the rare case of a super computer,
a closed source MS-OS is not adaptable. And MS sees
liitle reason to support super computers. Too little
business.

This is not as surprising as it sounds.

There are thousands of people worldwide capable of
porting Linux to a new architecture, and the source
code is readily available. For a new processor
or new computer architecture, Linux is the obvious
first choice.

You pick an already supported architecture similar
to your own and make a few modifications. It's a few
tens to a few hundred lines of code.
