With two processor cores on a single die, the dual-core
devices boost performance without requiring as much power, cooling or space
as two single-core processors. Projects currently
scheduled to run on the system include models of flows in implanted blood

computer-aided drug discovery. And fluid dynamics researchers will use the
supercomputer to model how heart pumps and other devices might aid blood
flow.
