This movie shows an intermediate stage in a large simulation of the distribution of matter in the Universe, the so-called cosmic web, accounting for the influence of dark energy. The simulation is evolving 1.1 trillion particles using HACC, a new computational framework developed to overcome the challenges posed by future supercomputing architectures. This movie shows a snapshot of the Universe at a redshift of z=0.7, when the Universe was 7.4 billion years old. The simulation is currently running on 32 racks of Mira, the Blue Gene/Q system at the Argonne Leadership Computing Facility; the visualization was performed on Argonne's Tukey cluster.
