Sorry.  I did a google search and pulled up e.g.

  http://www.beowulf.org/listarchives/beowulf/1999/11/0008.html

It was Emil Briggs from NCSU who wrote BLAS 1 routines hand optimized in
assembler for the Athlon.  There is a web-drop for his efforts in this
article:

  http://nemo.physics.ncsu.edu/~briggs/blas_src_v0.11_tar.gz

which still seems to exist.  I don't know if there are more recent
versions or if this ever went anywhere further, but Emil would likely
know at:

 Emil Briggs <briggs at tick.physics.ncsu.edu>

as of 1999.
