I've gotta brag a bit - we (I play with computers here at the
University of Tennessee and we manage ORNL) not only run the fastest
computer in the world we also have Kraken which is the fastest
University owned computer in the world and the third fastest overall.
Jaguar and Kraken sit across the hall from each other.
