ScaLAPACK on Cray Computers.

I will give a quick definition of Scalapack, a library of linear
algebra routines, and then discuss the symmetric eigenproblem. The first
step in finding the eigenvalues of a symmetric matrix is to tridiagonalize
the matrix and this first step will be the primary focus of my talk. I will
talk about the math behind how Scalapack does it, how its implimented, and
how well this works in practice on Cray Machines.
