Two-Grid Deflated Krylov Methods for Linear Equations
Ronald B. Morgan, Travis Whyte, Walter Wilcox +1
An approach is given for solving large linear systems that combines Krylov methods with use of two different grid levels. Eigenvectors are computed on the coarse grid and used to d…
Disconnected Loop Subtraction Methods in Lattice QCD
Travis Whyte, Suman Baral, Paul Lashomb +2
Noise subtraction methods are a set of techniques that aim to reduce the variance of signals in LQCD which are often flooded with noise. The standard approach is a pertubative subt…
Deflated GMRES with Multigrid for Lattice QCD
Travis Whyte, Walter Wilcox, Ronald B. Morgan
Lattice QCD solvers encounter critical slowing down for fine lattice spacings and small quark mass. Traditional matrix eigenvalue deflation is one approach to mitigating this probl…
Disconnected Loop Subtraction Methods in Lattice QCD
Suman Baral, Travis Whyte, Walter Wilcox +1
Lattice QCD calculations of disconnected quark loop operators are extremely computer time-consuming to evaluate. To compute these diagrams using lattice techniques, one generally u…
