A complex moment-based parallel eigensolver using the block
communication-avoiding Arnoldi procedure

For solving interior eigenvalue problems, complex moment-based eigensolvers
have been actively studied because of their high parallel efficiency. In
this talk, we introduce some typical complex moment-based eigensolvers and
analyzed their relationship. We also propose a novel method using a
communication-avoiding Arnoldi procedure (s-step Arnoldi procedure). We
evaluate the performance of the proposed method and compare with other
complex moment-based eigensolvers.
