Something in the Water Does Not Compute

Computational scientists at the Department of Energy’s Oak Ridge National Laboratory have published a study in the Journal of Chemical Theory and Computation that questions a long-accepted factor in simulating the molecular dynamics of water: the 2 femtosecond (one quadrillionth of a second) time step. The femtosecond is a timescale…

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…
