Optimal eigenvalue computation on a mesh multiprocessor

Conference ·
OSTI ID:149850
In this paper, we compare the costs of computing a single eigenvalue of a symmetric tridiagonal matrix by serial bisection and by parallel multisection on a mesh multiprocessor. We show how the optimal method for computing one eigenvalue depends on such variables as the matrix order and parameters of the multiprocessor used. We present the results of experiments on the 520-processor Intel Touchstone Delta to support our analysis.
