This photo gallery takes you inside Oak Ridge National Laboratory in the US, home to some of the world's fastest supercomputers. It's also the site where the first plutonium was refined to create the atomic bombs during World War II.

This is one row of the lab's Cray X1E, the largest vector supercomputer in the world and the 175th most powerful computer overall. It is rated for 18 teraflops of processing power. It is arrayed in multiple rows, with aisles for walking through. The computer is liquid-cooled, and piping was installed into the floor for that purpose.
