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…
