Don't forget Linux either :-)

We are using a production SMP machine with PAW (Physics Analysis 
Workstation software), CERNlib, and our own custom fortran code for 
ongoing data analysis from DESY and CERN.

The machine is an ASUS Dual P133, with an equivalent power of 60% of
An AlphaPC64 300MHz machine (at 1/5 the cost).

SMP on this machine is rock solid, and has been up since mid March.
Our production Linux kernel is 1.3.68-SMP.
