Asymptotic-preserving semi-implicit finite volume scheme for Extended Magnetohydrodynamics
Yi Han Toh, Joshua Dolence, Karthik Duraisamy
A Finite Volume (FV) scheme is developed for solving the extended magnetohydrodynamic (XMHD) equations, yielding accurate results in the ideal, resistive, and Hall MHD limits. This…
Characterizing Adaptive Mesh Refinement on Heterogeneous Platforms with Parthenon-VIBE
Akash Poptani, Alireza Khadem, Scott Mahlke +3
Hero-class HPC simulations rely on Adaptive Mesh Refinement (AMR) to reduce compute and memory demands while maintaining accuracy. This work analyzes the performance of Parthenon,…
Thermal Radiation Transport with Tensor Trains
Alex A. Gorodetsky, Patrick D. Mullen, Aditya Deshpande +4
We present a novel tensor network algorithm to solve the time-dependent, gray thermal radiation transport equation. The method invokes a tensor train (TT) decomposition for the spe…
