Dr. Alan Goodman, a physical anthropologist at Hampshire College and an adviser to the association, said, "there is no biological basis for race". The clusters shown in the Science article were driven by geography, not race, he said.
The Sequoia announcement is IBM's answer to Cray's Jaguar supercomputer, which last November challenged IBM's lead in the supercomputing race using clusters of Advanced Micro Devices chips to achieve processing speeds of 1.6 petaflops, 60% faster than the IBM Road Runner supercomputer that broke the so-called "petaflop barrier" in June.
Early in the race, Mosop clustered at the front with a pack of elite racers, three of them pacesetters.
