I understand that Cray has implemented the BLAS (Basic Linear Algebra
Subroutines) in assembler for their machines.  The means all of the
BLAS: levels 1, 2, and 3 (I'm not sure about sparse-BLAS-1, though).

Is anyone out there aware of other vendors implementing the BLAS for
their machines?

On a Sun with FPA, for example, the routines could take advantage of
the 2x2, 3x3, and 4x4 matrix and vector operations on the FPA.
I would expect that most presently available could get improved
performance from special implementations of the BLAS (as opposed to
just compiling the FORTRAN version).
