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…
Toward Efficient Polynomial Preconditioning for GMRES
Jennifer A. Loe, Ronald B. Morgan
We present a polynomial preconditioner for solving large systems of linear equations. The polynomial is derived from the minimum residual polynomial (the GMRES polynomial) and is m…
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…
