Title: Development of a moment-based parallel eigensolver and its applications
Abstract:
In this talk, we present a parallel eigensolver for large-scale interior eigenvalue
problems. We have proposed a method for linear and nonlinear eigenvalue problems that uses complex moments obtained by contour integral. This method is called the SS method. We discuss a parallel implementation of the SS method to achieve good parallel scalability according to the hierarchical structure of the method. We also present a method for estimating eigenvalue counts in a given interval. Some
numerical examples derived from vibration analysis and nano-materials simulations are shown.
