Block Iterative Eigensolvers for Sequences of Correlated Eigenvalue Problems
Edoardo Di Napoli, Mario Berljafa
In Density Functional Theory simulations based on the LAPW method, each self-consistent field cycle comprises dozens of large dense generalized eigenproblems. In contrast to real-s…

Dissecting the FEAST algorithm for generalized eigenproblems
Lukas Krämer, Edoardo Di Napoli, Martin Galgon +2
We analyze the FEAST method for computing selected eigenvalues and eigenvectors of large sparse matrix pencils. After establishing the close connection between FEAST and the well-k…
