Deflated BiCGStab for linear equations in QCD problems
Abdou Abdel-Rehim, Ronald B. Morgan, Walter Wilcox
The large systems of complex linear equations that are generated in QCD problems often have multiple right-hand sides (for multiple sources) and multiple shifts (for multiple masse…
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…
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…
