Improving the parallel performance of a domain decomposition preconditioning technique in the Jacobi–Davidson method for large scale eigenvalue problems

Abstract: C e n t r u m v o o r W i s k u n d e e n I n f o r m a t i c a Modelling, Analysis and Simulation Modelling, Analysis and SimulationImproving the parallel performance of a domain decomposition preconditioning technique in the Jacobi-Davidson method for large scale eigenvalue problems M. Genseberger This report discusses the aspect that the original strategy can be improved. For large scale eigenvalue problems that need a massively parallel treatment this aspect turns out to be nontrivial. The impact on the pa… Show more

“…However, Davidson methods may present better performance computing interior eigenvalues and/or in generalized eigenproblems when exact solves with A − τ B are unaffordable, but some approximations are available, so-called preconditioners, [Davidson, 1975;van Lenthe and Pulay, 1990;Crouzeix et al, 1994;Heuveline et al, 1997;Arbenz et al, 2006;Genseberger, 2010].…”

“…This dynamic criterion comes from the Newton methods and the use in Jacobi-Davidson is suggested in [Fokkema et al, 1999], and tested in [Genseberger, 2010;. It is well-know that in the first iterations of the Davidson-type methods the extraction method usually produces poor eigenpair approximations and the target τ may be a relatively closer approximation to an exact eigenvalue [Morgan and Scott, 1986].…”
