Exascale’s New Frontier: SOLLVE

PI: Sunita Chandrasekaran, Brookhaven National Laboratory, University of Delaware In 2016, the Department of Energy’s Exascale Computing Project (ECP) set out to develop advanced software for the arrival of exascale-class supercomputers capable of a quintillion (1018) or more calculations per second. That leap meant rethinking, reinventing, and optimizing dozens of…
