Suppression of Richtmyer-Meshkov instability via special pairs of shocks and phase transitions
W. J. Schill, M. R. Armstrong, J. H. Nguyen +9
The classical Richtmyer-Meshkov instability is a hydrodynamic instability characterizing the evolution of an interface following shock loading. In contrast to other hydrodynamic in…
Accelerating High-Order Mesh Optimization Using Finite Element Partial Assembly on GPUs
Jean-Sylvain Camier, Veselin Dobrev, Patrick Knupp +4
In this paper we present a new GPU-oriented mesh optimization method based on high-order finite elements. Our approach relies on node movement with fixed topology, through the Targ…
Understanding Power and Energy Utilization in Large Scale Production Physics Simulation Codes
Adam Bertsch, Michael R. Collette, Shawn A. Dawson +8
Power is an often-cited reason for the move to advanced architectures on the path to Exascale computing. This is due to practical considerations related to delivering enough power…
Matrix-free approaches for GPU acceleration of a high-order finite element hydrodynamics application using MFEM, Umpire, and RAJA
Arturo Vargas, Thomas M. Stitt, Kenneth Weiss +4
With the introduction of advanced heterogeneous computing architectures based on GPU accelerators, large-scale production codes have had to rethink their numerical algorithms and i…
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…
Simulation-Driven Optimization of High-Order Meshes in ALE Hydrodynamics
Veselin Dobrev, Patrick Knupp, Tzanio Kolev +3
In this paper we propose tools for high-order mesh optimization and demonstrate their benefits in the context of multi-material Arbitrary Lagrangian-Eulerian (ALE) compressible sho…
