As Frontier, the world’s first exascale supercomputer, was being assembled at the Oak Ridge Leadership Computing Facility in 2021, understanding its performance on mixed-precision calculations remained a difficult prospect. That gap in understanding wasn’t an oversight but rather a sign of just how novel supercomputer systems that excel at mixed precision remain in computational science, which has been dominated by double precision–focused systems for almost its entire history.
