At number four, the Kraken XT5 is also the world's fastest academic supercomputer. Effectively the same computer as the Jaguar XT5 in first place, the Kraken is much smaller having only 98,928 cores. Kraken is funded by the National Institute for Computational Sciences at the University of Tennessee but is housed at the Oak Ridge National Laboratory. Also, I love this image too of the Kraken sea creature.

The fifth most powerful supercomputer is also the most powerful in Europe. Housed at German company Forschungszentrum Juelich (which specializes in health, energy, environment, and information technology research), JUGENE is an IBM computer with 294,912 cores.

NASA's most powerful supercomputer weighs in at number six in the world. Operating 81,920 cores in an SGI system, the Pleiades cranked out 772.70 teraflops and is housed at the NASA Ames Research Center.
