Reduction to condensed form for the eigenvalue problem on distributed memory architectures
Jack J. Dongarra, Robert A. Geijn · 1992
In this paper, we describe a parallel implementation for the reduction of general and symmetric matrices to Hessenberg and tridiagonal form, respectively. The methods are based on LAPACK sequential codes and use a panel-wrapped mapping of matrices to nodes. Results from experiments on the Intel Touchstone Delta are given.
