Disconnected Loops with Twisted Mass Lattice QCD
Walter Wilcox, Dean Darnell, Ron Morgan +1
We give a general introduction and discussion of the issues involved in using the twisted mass formulation of lattice fermions in the context of disconnected loop calculations, inc…

Deflated Iterative Methods for Linear Equations with Multiple Right-Hand Sides
Ronald B. Morgan, Walter Wilcox
A new approach is discussed for solving large nonsymmetric systems of linear equations with multiple right-hand sides. The first system is solved with a deflated GMRES method that…

Deflation of Eigenvalues for GMRES in Lattice QCD
Ronald B. Morgan, Walter Wilcox
Versions of GMRES with deflation of eigenvalues are applied to lattice QCD problems. Approximate eigenvectors corresponding to the smallest eigenvalues are generated at the same ti…
