Automated Grammar-based Algebraic Multigrid Design With Evolutionary Algorithms
Dinesh Parthasarathy, Wayne Mitchell, Arjun Gambhir +2
Although multigrid is asymptotically optimal for solving many important partial differential equations, its efficiency relies heavily on the careful selection of the individual alg…
Large-scale Multigrid with Adaptive Galerkin Coarsening
Fabian Böhm, Nils Kohl, Harald Köstler +1
We propose a robust, adaptive coarse-grid correction scheme for matrix-free geometric multigrid targeting PDEs with strongly varying coefficients. The method combines uniform geome…
Highly Efficient Lattice-Boltzmann Multiphase Simulations of Immiscible Fluids at High-Density Ratios on CPUs and GPUs through Code Generation
Markus Holzer, Martin Bauer, Ulrich Rüde
A high-performance implementation of a multiphase lattice Boltzmann method based on the conservative Allen-Cahn model supporting high-density ratios and high Reynolds numbers is pr…
lbmpy: Automatic code generation for efficient parallel lattice Boltzmann methods
Martin Bauer, Harald Köstler, Ulrich Rüde
Lattice Boltzmann methods are a popular mesoscopic alternative to macroscopic computational fluid dynamics solvers. Many variants have been developed that vary in complexity, accur…
A Scalable and Extensible Checkpointing Scheme for Massively Parallel Simulations
Nils Kohl, Johannes Hötzer, Florian Schornbaum +5
Realistic simulations in engineering or in the materials sciences can consume enormous computing resources and thus require the use of massively parallel supercomputers. The probab…
