The Beating Heart of the World’s First Exascale Supercomputer

The world’s latest fastest supercomputer, Frontier at Oak Ridge National Lab, in Tennessee, is so powerful that it operates faster than the next seven best supercomputers combined and more than twice as well as the No. 2 machine. Frontier is not only the first machine to break the exascale barrier, a threshold of a billion billion calculations per second, but is also ranked No. 1 as the world’s most energy-efficient supercomputer. Now the companies that helped build Frontier, Advanced Micro Devices (AMD) and Hewlett Packard Enterprise (HPE), reveal the electronic tricks that make the supercomputer tick.
