| The Avalon folks got excellent results with their alpha cluster. The

A location seems to be in order. Look at

http://www.cs.utk.edu/~ghenry/distrib/

for the BLAS libraries (and other assorted math libraries for PII and
PPro processors) as well as links to information about the ASCI RED
machine here at Sandia.
