The universe just got a whole lot bigger — or at least in the world of computer simulations. In early November, researchers at the U.S. Department of Energy’s (DOE) Argonne National Laboratory used the world’s fastest supercomputer to run the largest astrophysical simulation of the universe ever conducted. The achievement was made using the Frontier supercomputer at Oak Ridge National Laboratory (ORNL). The calculations set a new benchmark for cosmological hydrodynamics simulations and provide a...
