At Oak Ridge National Laboratory, a supercomputer named Frontier has broken the exascale computing barrier, meaning it can calculate more than a million trillion floating-point operations per second. In this episode, C&EN reporters Craig Bettenhausen and Ariana Remmel discuss how Frontier works and what that kind of power could mean for computational chemistry. C&EN Uncovered, a new project from C&EN’s podcast, Stereo Chemistry, offers a deeper look at subjects from recent cover stories.
