On second read this was confusing. The best STREAM results from using
the Intel compiler on Linux. The ones I've been doing and that Scott
has been running are using regular gcc instead. So when the new AMD
system is clearing 75MB/s in the little test set I'm trying to get
automated, that's actually a conservative figure, given that a compiler
swap is almost guaranteed to boost results a bit too.
