Meet the new fastest supercomputer in the world

Later this month, when a ranking of supercomputers called the TOP500 comes out, the highest spot is expected to go to an American machine called Summit. If you wanted to put Summit on your desk, you'd need a workstation that's about the size of two tennis courts. That's because this particular machine occupies 5,600 square feet of space. Its guts spread across more than 250 cabinets, each about the size of a refrigerator. And within the system is 185 miles of fiber optic cables, about enough to stretch from New York City to Providence, Rhode Island.
