Multi-physics Preconditioning for Thermally Activated Batteries
Malachi Phillips
Thermal batteries, also known as molten-salt batteries, are single-use reserve power systems activated by pyrotechnic heat generation, which transitions the solid electrolyte into…
Smoothed aggregation algebraic multigrid for problems with heterogeneous and anisotropic materials
Max Firmbach, Malachi Phillips, Christian Glusa +3
This paper introduces a material-aware strength-of-connection measure for smoothed aggregation algebraic multigrid methods, aimed at improving robustness for scalar partial differe…
Optimal Chebyshev Smoothers and One-sided V-cycles
Malachi Phillips, Paul Fischer
The solution to the Poisson equation arising from the spectral element discretization of the incompressible Navier-Stokes equation requires robust preconditioning strategies. One s…
Tuning Spectral Element Preconditioners for Parallel Scalability on GPUs
Malachi Phillips, Stefan Kerkemeier, Paul Fischer
The Poisson pressure solve resulting from the spectral element discretization of the incompressible Navier-Stokes equation requires fast, robust, and scalable preconditioning. In t…
Highly Optimized Full-Core Reactor Simulations on Summit
Paul Fischer, Elia Merzari, Misun Min +8
Nek5000/RS is a highly-performant open-source spectral element code for simulation of incompressible and low-Mach fluid flow, heat transfer, and combustion with a particular focus…
GPU Algorithms for Efficient Exascale Discretizations
Ahmad Abdelfattah, Valeria Barra, Natalie Beams +24
In this paper we describe the research and development activities in the Center for Efficient Exascale Discretization within the US Exascale Computing Project, targeting state-of-t…
NekRS, a GPU-Accelerated Spectral Element Navier-Stokes Solver
Paul Fischer, Stefan Kerkemeier, Misun Min +8
The development of NekRS, a GPU-oriented thermal-fluids simulation code based on the spectral element method (SEM) is described. For performance portability, the code is based on t…
