Massive Galaxy Scale Simulations Present Unique Compute Demands

The HPC User Forum was established in 1999 to promote the health of the global HPC industry and address issues of common concern to users. In April 2023, the 82nd HPC User Forum took place in Princeton, New Jersey. This update summarizes a presentation from that conference given by Molly Peeples, tenured associate astronomer at the Space Telescope Science Institute and astrophysics theorist. Also, a research scientist at Johns Hopkins University, Peeples leads the Figuring Out Gas & Galaxies In Enzo (FOGGIE) collaboration. Her discussion at the April 2023 meeting covered some of the recent laboratory activities as well as milestones and her vision for the future. Additional topics included recent activities in the FOGGIE collaboration, simulation domain factors and their relationship to compute demands, as well as the technological future of the field of galaxy simulation.
