Technical and scientific advances

The project, led by Salman Habib, director of the computer sciences division at Argonne, combines two critical components of the universe: dark matter, which interacts primarily through gravity, and conventional or atomic matter. This comprehensive approach is essential to fully grasp the multidimensional nature of the universe.

The challenges of cosmological hydrodynamic simulations

These simulations represent a significant computational challenge, requiring considerable resources and the integration of complex physics to simulate dark and atomic matter over long periods of time. The implications of these simulations are broad, allowing direct comparisons with observations from large telescopes, such as the Rubin Observatory in Chile.

The key role of the HACC code

The code that powered these simulations is the Hardware/Hybrid Accelerated Cosmology Code (HACC), initially developed for petaflop-level machines and which has undergone significant updates as part of the ExaSky project. This project, part of the Department of Energy's Exascale Computing Project (ECP), brought together thousands of experts to lay the groundwork for exascale-class supercomputers.

Frontier's influence on scientific research

Beyond its impressive speed, Frontier has played a key role in various areas of scientific research over the past year. Although recently surpassed in speed by Lawrence Livermore National Laboratories' El Capitan supercomputer, Frontier continues to set standards in high-performance computing (HPC).

Notable projects and innovations

Projects such as the simulation of water molecules at room temperature at the atomic level, studies on the metastability of diamonds under extreme pressure, and discoveries on the nuclear magnetic excitation of calcium-48 demonstrate the capabilities of the supercomputer to advance the scientific inquiry and to deepen our understanding of complex phenomena.
