I have tested my CFD code using Dec's Fortran 90/95 compiler on 2 identical Alpha 21264's @500Mhz.  The ratio of
time to finish for Tru64/linux was .85.  This is right in line with what Dec was saying the performance penalty
for using Linux on their machines was.  Does anyone know why this is?  I heard something about Linux not having
page coloring, which I am not familiar with.
