- W160828896 abstract "In this paper, we investigate parallel solution of the nonsymmetric tridiagonal eigenproblem by the LR method, inverse iteration, and Rayleigh quotient iteration on a distributed-memory computer. We examine serial computation of eigenvalues followed by parallel computation of block- or wrap-distributed eigenvectors and parallel computation of eigenvalues using a block algorithm. We also consider pipelining the calculation of eigenvalues with the calculation of the eigenvectors. Experiments on an Intel iPSC/860, where the communication to computation ratio is very large, show that serial eigenvalue computation with wrap-mapped eigenvector computation has the lowest execution time. 3 refs., 1 fig., 1 tab." @default.
