The document discusses NVIDIA's role in powering the world's fastest supercomputers. It notes that the Summit supercomputer at Oak Ridge National Laboratory is now the fastest system, powered by 27,648 Volta Tensor Core GPUs to achieve over 122 petaflops. NVIDIA GPUs also power 17 of the world's 20 most energy efficient supercomputers, including Europe's fastest Piz Daint and Japan's fastest Fugaku supercomputer. Over 550 applications are now accelerated using NVIDIA GPUs.
