An Asymptotic Preserving Maxwell Solver Resulting in the Darwin Limit of Electrodynamics
Yingda Cheng, Andrew J. Christlieb, Wei Guo +1
In plasma simulations, where the speed of light divided by a characteristic length is at a much higher frequency than other relevant parameters in the underlying system, such as th…
Pipeline Implementations of Neumann-Neumann and Dirichlet-Neumann Waveform Relaxation Methods
Benjamin W. Ong, Bankim C. Mandal
This paper is concerned with the reformulation of Neumann-Neumann Waveform Relaxation (NNWR) methods and Dirichlet-Neumann Waveform Relaxation (DNWR) methods, a family of parallel…
A Distributed and Incremental SVD Algorithm for Agglomerative Data Analysis on Large Networks
M. A. Iwen, B. W. Ong
In this paper, we show that the SVD of a matrix can be constructed efficiently in a hierarchical approach. Our algorithm is proven to recover the singular values and left singular…
A New Family of Regularized Kernels for the Harmonic Oscillator
Benjamin Ong, Andrew Christlieb, Bryan Quaife
In this paper, a new two-parameter family of regularized kernels is introduced, suitable for applying high-order time stepping to N-body systems. These high-order kernels are deriv…
Revisionist Integral Deferred Correction with Adaptive Stepsize Control
Andrew J. Christlieb, Colin B. Macdonald, Benjamin W. Ong +1
Adaptive stepsize control is a critical feature for the robust and efficient numerical solution of initial-value problems in ordinary differential equations. In this paper, we show…
