yes, but the binaries I downloaded are for the P4 processor, so I'm not 
sure how much more specific I can get. I'm going to give it a try.

This does bring up a point, however. Why is lapack usually linked 
statically? I usually link statically so that I can move applications to 
a different system without worrying about what libraries are installed 
there. However, with lapack/blas, you want to use a library compiled for 
that particular machine, so it seems to make more sense to use dynamic 
ones. Besides, it would be easier to compare performance if all I had to 
do was drop a new *.so in place.
