摘要

提出了一种可伸缩的对称矩阵三对角化简算法。它使用单侧旋转而不是相似变换。这允许以低通信量实现独立于数据分布的实现。富士通AP 1000和VPP 500的计时显示出良好的性能。

A distribution independent algorithm for the reduction to tridiagonal form using one-sided rotations

A scalable algorithm for the reduction to tridiagonal form of symmetric matrices is developed. It uses one-sided rotations instead of similarity transforms. This allows a data distribution independent implementation with low communication volume. Timings on the Fujitsu AP 1000 and VPP 500 show good performance.<>
