A group of scientists presented a set of simulations called AbacusSummit. It contains almost 60 trillion particles and is capable of making more accurate calculations about the processes taking place in the Universe. This will help in further exploration of space. The set of simulators was described in the scientific journal Monthly Notices of the Royal Astronomical Society.

AbacusSummit consists of over 160 N-body simulations and simulates how particles interact through gravity in the Universe. “This set is so large that it probably has more particles than other N-body simulations combined,” said Lehman Garrison, lead author of one article and a CCA researcher.

The kit was modeled on the US Department of Energy Summit computer at the Oak Ridge Leadership Computing Facility in Tennessee. The machine has a variety of GPUs that do an excellent job of parallel processing. Summit is the fastest computer in the world at the time of its creation.

The team of scientists wrote the Abacus code to take advantage of Summit’s parallel processing capabilities so that multiple computations can be performed concurrently. Because of its design, Abacus can refresh 70 million particles per second on each node of the Summit supercomputer. The code can even analyze the simulation as it runs, identifying patches of dark matter indicative of bright galaxies that will be the focus of upcoming research.

AbacusSummit will soon come in handy, as in the coming years, as a result of several studies, they will compile space maps with very accurate detail. One of the goals of these high-budget missions is to add knowledge about what the universe looks like and what processes take place there.
