Towards Exascale for Wind Energy Simulations
Misun Min, Michael Brazell, Ananias Tomboulides +3
We examine large-eddy-simulation modeling approaches and computational performance of two open-source computational fluid dynamics codes for the simulation of atmospheric boundary…
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…
Efficient Exascale Discretizations: High-Order Finite Element Methods
Tzanio Kolev, Paul Fischer, Misun Min +27
Efficient exploitation of exascale architectures requires rethinking of the numerical algorithms used in many large-scale applications. These architectures favor algorithms that ex…
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…
Symmetry Breaking, Anomalous Scaling and Large-Scale Flow Generation in a Convection Cell
Ananias G. Tomboulides, Victor Yakhot
We consider a convection process in a thin loop. At a first transition leading to the generation of corner vortices is observed. At higher a coherent lar…
