The code that they were using was a CFD code called TAU and they were
getting over 90% efficiency on the 2nd processor on the Dual Opteron
Thanks for your information Tim & Greg
Have a great 4th of July!

just curious -- what benchmark was being used?

running linpack and linking against the goto blas
(http://www.cs.utexas.edu/users/flame/goto/), a two-cpu opteron
achieved 87% of peak.
a two-cpu itanium 2 achieved 98% of peak.
