The fine people on this list can provide a large number of reasons
for choosing Linux over NT. Let me give you an empirical observation.

I have not read about or seen any reference many production
NT clusters. (Those that are actually doing something useful)
On the other hand, I can tell you we have quite a few customers who
are designing aircraft, computing molecules, and finding oil
with Linux clusters.  There are many other applications out
there running day in and day out on Linux clusters. I have not
seen this with NT. My only conclusion is that if it worked
well you would see more. One sure reason is that HPC (High Performance
Computing) has been and will continue to be a *NIX world. Just
seems to work better.
