Accelerated Computing Powering World’s Fastest Supercomputer

Call it the most powerful scientific tool ever built. Call it a new paradigm of computing. Just don’t call it slow, because whatever number you look at, Summit — which made its debut Friday at the Oak Ridge National Laboratory — is flat-out fast. This massive machine, powered by 27,648 of our Volta Tensor Core GPUs, can perform more than three exaops, or 3 billion billion calculations per second. That’s more than 100 times faster than Titan, previously the fastest U.S. supercomputer, completed just five years ago. And 95 percent of that computing power comes from GPUs.
