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…
