Argonne physicists are using Mira to perform simulations of Large Hadron Collider (LHC) experiments with a leadership-class supercomputer for the first time, shedding light on a path forward for interpreting future LHC data. Researchers at the Argonne Leadership Computing Facility (ALCF) helped the team optimize their code for the supercomputer, which has enabled them to simulate billions of particle collisions faster than ever before.
