After years of trailing the Chinese and Japanese, the United States now has three of the four fastest supercomputers in the world.
Mira, another brand-new Department of Energy supercomputer, is capable of 10.1 petaflops.
The IBM Blue Gene supercomputer is housed at the Argonne National Laboratory in Illinois and is used for astronomy, energy, climate and materials research -- just like the more powerful Titan supercomputer.
Current research being conducted on Mira includes studies of exploding stars, subatomic particles, seismic hazards, materials used in nuclear reactors, and advanced energy technologies.
