Mixed Precision: A Strategy for New Science Opportunities

OLCF computational scientist Wayne Joubert successfully exploited the Summit supercomputer’s low-precision capabilities to accelerate a genomics application to exascale speeds. Since the days of vector supercomputers, computational scientists have relied on high-precision arithmetic to accurately solve a wide range of problems, from modeling nuclear reactors to predicting supernova physics to…
