The AbacusSummit suite comprises hundreds of simulations of how gravity shaped the distribution of dark matter throughout the universe. Here, a snapshot of one of the simulations is shown at a zoom scale of 1.2 billion light-years across. The simulation replicates the large-scale structures of our universe, such as the cosmic web and colossal clusters of galaxies.

Abacus leverages parallel computer processing to drastically speed up its calculations of how particles move about due to their gravitational attraction. A sequential processing approach (top) computes the gravitational tug between each pair of particles one by one. Parallel processing (bottom) instead divides the work across multiple computing cores, enabling the calculation of multiple particle interactions simultaneously.
