This thing is a beast: "The K Computer, built by Fujitsu, currently combines 68544 SPARC64 VIIIfx CPUs, each with eight cores, for a total of 548,352 cores—almost twice as many as any other system in the TOP500. The K Computer is also more powerful than the next five systems on the list combined." Interesting that they use the Sparc. I would also have guessed there would be more commercial/private companies in the Top10.
