Performance-Portable Binary Neutron Star Mergers with AthenaK
Jacob Fields, Hengrui Zhu, David Radice +4
We introduce an extension to the AthenaK code for general-relativistic magnetohydrodynamics (GRMHD) in dynamical spacetimes using a 3+1 conservative Eulerian formulation. Like the…

Performance-Portable Numerical Relativity with AthenaK
Hengrui Zhu, Jacob Fields, Francesco Zappa +6
We present the numerical relativity module within AthenaK, an open source performance-portable astrophysics code designed for exascale computing applications. This module employs t…

Numerical relativity simulations of compact binaries: comparison of cell- and vertex-centered adaptive meshes
Boris Daszuta, William Cook, Peter Hammond +4
Given the compact binary evolution problem of numerical relativity, in the finite-difference, block-based, adaptive mesh refinement context, choices must be made on how evolved fie…
