Beyond Sierra and Summit, the U.S. Department of Energy has invested an additional $100 million in paving the way toward exascale supercomputing. But such investments won’t benefit just the few big U.S. government labs that can afford such machines. The new computer architectures needed to make an exascale supercomputer could also make supercomputing more widely accessible, says Sumit Gupta, general manager for the Tesla accelerated computing business at Nvidia.
