First attempt
This attempt is the first run I did. It probably needs tuning because it SUCKS! This is the result I received with the use of VSIPL as the math libraries. I am now working on getting BLAS installed to test against those instead.
==Second Attempt== OK... this time using BLAS instead of VSIPL, I am getting much better results: <pre> ============================================================================ HPLinpack 1.0a -- High-Performance Linpack benchmark -- January 20, 2004 Written by A.
