  • Cosmic Structure of the Dark Universe

Argonne Scientists Probe the Cosmic Structure of the Dark Universe

The origin of dark energy and dark matter—together accounting for 95% of the mass energy of the Universe—remains mysterious. To learn more about their ultimate nature, a team of researchers led by Argonne National Laboratory’s Salman Habib and co-PI Katrin Heitmann is carrying out some of the largest high-resolution simulations of the distribution of matter in the Universe. The researchers are resolving galaxy-scale mass concentrations over observational volumes representative of state-of-the-art sky surveys by using Mira, a petascale supercomputer at the Argonne Leadership Computing Facility (ALCF). A key aspect of the project involves developing a major simulation suite covering approximately 100 different cosmologies—an essential resource for interpreting next-generation observations. This initiative targets an approximately two- to three-orders-of-magnitude improvement over currently available resources.

New Argonne Supercomputer Ties for First Place on the Graph 500 Benchmark for Data-Intensive Computing

Mira, located at the Argonne Leadership Computing Facility (ALCF), and Sequoia, located at Lawrence Livermore National Laboratory, each achieved a score of over 3,500 billion graph edges per second, or 3.5 TEPS. The Graph 500 benchmark evaluates machine performance while running data-intensive analytic applications and is a measure of the machine’s communications capabilities and computational power.
