    Appl Math: James Stone on "Astrophysical Fluid Dynamics at Exascale"

    McCormick-Engineering Sciences and Applied Mathematics (ESAM)

    11:15 AM M416, Technological Institute

    EVENT DETAILS

    Title: Astrophysical Fluid Dynamics at Exascale

    Speaker: James Stone, Institute for Advanced Study

    Abstract: Most of the visible matter in the Universe is a plasma -- that is a dilute gas of electrons, ions, and neutral particles -- interacting with both magnetic and radiation fields. Studying the structure and dynamics of astrophysical systems, from stars and planets, to
    galaxies and the large-scale structure of the Universe itself, usually requires numerical methods to solve the coupled equations of compressible radiation magnetohydrodynamics (MHD). Robust numerical algorithms for modeling astrophysical fluids, including new methods for calculating radiation transport in relativistic flows, will be discussed. Efficient implementation of these methods on modern high-performance computing systems is crucial, and an approach based on the Kokkos programming model that enables performance portability will be described. Performance on a variety of architectures of a new adaptive mesh refinement (AMR) astrophysical MHD code will be given, including scaling on up to 65536 GPUs on the OLCF Frontier exascale computer. Finally, a case study will be presented that demonstrates some of the many new insights that have come from applying computational methods to one particular problem: how plasma accretes onto the black holes in the centers of galaxies.
