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…
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…
Deflated GMRES for Systems with Multiple Shifts and Multiple Right-Hand Sides
Dean Darnell, Ronald B. Morgan, Walter Wilcox
We consider solution of multiply shifted systems of nonsymmetric linear equations, possibly also with multiple right-hand sides. First, for a single right-hand side, the matrix is…
