Simple and efficient GPU parallelization of existing H-Matrix accelerated BEM code
Kerstin Vater, Timo Betcke, Boris Dilba
In this paper, we demonstrate how GPU-accelerated BEM routines can be used in a simple black-box fashion to accelerate fast boundary element formulations based on Hierarchical Matr…
High-productivity, high-performance workflow for virus-scale electrostatic simulations with Bempp-Exafmm
Tingyu Wang, Christopher D. Cooper, Timo Betcke +1
Biomolecular electrostatics is key in protein function and the chemical processes affecting it. Implicit-solvent models via the Poisson-Boltzmann (PB) equation provide insights wit…
Coupling finite and boundary element methods to solve the Poisson--Boltzmann equation for electrostatics in molecular solvation
Michal Bosy, Matthew W. Scroggs, Timo Betcke +2
The Poisson--Boltzmann equation is widely used to model electrostatics in molecular systems. Available software packages solve it using finite difference, finite element, and bound…
Benchmarking preconditioned boundary integral formulations for acoustics
Elwin van 't Wout, Seyyed R. Haqshenas, Pierre Gélat +2
The boundary element method (BEM) is an efficient numerical method for simulating harmonic wave propagation. It uses boundary integral formulations of the Helmholtz equation at the…
Calderón preconditioning of PMCHWT boundary integral equations for scattering by multiple absorbing dielectric particles
Antigoni Kleanthous, Timo Betcke, David P. Hewett +2
We consider the simulation of electromagnetic scattering by single and multiple isotropic homogeneous dielectric particles using boundary integral equations. Galerkin discretizatio…
M2L Translation Operators for Kernel Independent Fast Multipole Methods on Modern Architectures
Srinath Kailasa, Timo Betcke, Sarah El Kazdadi
Hardware trends favor algorithm designs that maximize data reuse per FLOP. We develop and benchmark high-performance Multipole-to-Local (M2L) translation operators for the kernel-i…
