ORNL Researchers Develop Open-Source Mixed-Precision Benchmark Tool

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…

Benchmarking Mixed-Precision Performance

Today at ISC High Performance 2021, a European virtual conference for high-performance computing (HPC), the Oak Ridge Leadership Computing Facility’s (OLCF’s) Summit was ranked as the world’s second-fastest supercomputer in the 57th TOP500 list. But it also took second place in a relatively new benchmark test apart from the main…

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…
