Architecture Specific Generation of Large Scale Lattice Boltzmann Methods for Sparse Complex Geometries
Philipp Suffa, Markus Holzer, Harald Köstler +1
We implement and analyse a sparse / indirect-addressing data structure for the Lattice Boltzmann Method to support efficient compute kernels for fluid dynamics problems with a high…
Code Generation and Performance Engineering for Matrix-Free Finite Element Methods on Hybrid Tetrahedral Grids
Fabian Böhm, Daniel Bauer, Nils Kohl +5
This paper introduces a code generator designed for node-level optimized, extreme-scalable, matrix-free finite element operators on hybrid tetrahedral grids. It optimizes the local…
A Continuous Benchmarking Infrastructure for High-Performance Computing Applications
Christoph Alt, Martin Lanser, Jonas Plewinski +5
For scientific software, especially those used for large-scale simulations, achieving good performance and efficiently using the available hardware resources is essential. It is im…
Towards Code Generation for Octree-Based Multigrid Solvers
Richard Angersbach, Sebastian Kuckuck, Harald Köstler
This paper presents a novel method designed to generate multigrid solvers optimized for octree-based software frameworks. Our approach focuses on accurately capturing local feature…
waLBerla-wind: a lattice-Boltzmann-based high-performance flow solver for wind energy applications
Helen Schottenhamml, Ani Anciaux-Sedrakian, Frédéric Blondel +2
This article presents the development of a new wind turbine simulation software to study wake flow physics. To this end, the design and development of waLBerla-wind, a new simulato…
