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

    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.
