Seed methods for linear equations in lattice qcd problems with multiple right-hand sides
Abdou Abdel-Rehim, Ronald B. Morgan, Walter Wilcox
We consider three improvements to seed methods for Hermitian linear systems with multiple right-hand sides: only the Krylov subspace for the first system is used for seeding subseq…
Tests of Electric Polarizability on the Lattice
Victor X. Guerrero, Walter Wilcox, Joe Christensen
Using clover fermions on CP-PACS dynamical configurations, we consider a number of ways of measuring hadronic electric polarizability, an effect in hadron masses…
Deflated Hermitian Lanczos Methods for Multiple Right-Hand Sides
Abdou M. Abdel-Rehim, Ronald B. Morgan, Dywayne Nicely +1
A deflated and restarted Lanczos algorithm to solve hermitian linear systems, and at the same time compute eigenvalues and eigenvectors for application to multiple right-hand sides…
