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 …

We present hipBone, an open-source performance-portable proxy application for the
Nek5000 (and NekRS) computational fluid dynamics applications. HipBone is a fully GPU …

We investigate the applicability of a high-order Spectral Element Method (SEM) to density
based topology optimization of unsteady flows in two dimensions. Direct Numerical …

Most high-end computers adopt hybrid architecture, porting a large-scale scientific code
onto accelerators is necessary. The paper presents a generic method for porting large-scale …

Heterogeneous architectures consisting of both central processing units and graphics
processing units are common in contemporary computer systems. For that reason, several …

Advances in computational capabilities have transformed national security. For the US
nuclear deterrent these advances have allowed wiser options for a production complex that …

Although GPUs can offer higher computing power at low power consumption, their low-level
programming can be relatively complex and consume programming time. For this reason …

Computational fluid dynamics (CFD) simulations are essential tools in various scientific and
engineering disciplines. Nek5000 is a CFD Fortran code based on spectral element …

We present hipBone, an open source performance-portable proxy application for the
Nek5000 (and NekRS) CFD applications. HipBone is a fully GPU-accelerated C++ …

This work presents a state-of-the-art computational approach for performing large-scale
simulations of turbulence on heterogeneous compute nodes. The approach proposed …
