The first of the two accompanying images shows the IBM Blue Gene supercomputer at Argonne Labs. It houses 250,000 processors in 72 cabinets connected by an optical network. It can perform approximately 1015 operations per second—a million times faster than the chip in your smartphone. The image on the next page is a beautiful graph of connections between Internet sites. The Internet is a supercomputer grown from a billion machines and several billion people.
