Initial Guesses for Sequences of Linear Systems in a GPU-Accelerated Incompressible Flow Solver
Anthony P. Austin, Noel Chalmers, Tim Warburton
We consider several methods for generating initial guesses when iteratively solving sequences of linear systems, showing that they can be implemented efficiently in GPU-accelerated…
Multivariate Rational Approximation
Anthony P. Austin, Mohan Krishnamoorthy, Sven Leyffer +3
We present two approaches for computing rational approximations to multivariate functions, motivated by their effectiveness as surrogate models for high-energy physics (HEP) applic…
Simultaneous Sensing Error Recovery and Tomographic Inversion Using an Optimization-based Approach
Anthony P. Austin, Zichao Wendy Di, Sven Leyffer +1
Tomography can be used to reveal internal properties of a 3D object using any penetrating wave. Advanced tomographic imaging techniques, however, are vulnerable to both systematic…
Trigonometric Interpolation and Quadrature in Perturbed Points
Anthony P. Austin, Lloyd N. Trefethen
The trigonometric interpolants to a periodic function in equispaced points converge if is Dini-continuous, and the associated quadrature formula, the trapezoidal rule, conv…
