| 内容記述 | In this paper a new parallel implementation method for computing eigenvalues in symmetric tridiagonal eigensolver is proposed. In this method natural parallelism for multiple eigenvalue computations and multi-section points of the eigenvalue searching are used. The performance evaluatiorl results with the HITACHI SR8000 using 8 processors per node indicated that:(1) maximum 7.7x speedup to a case of using conventional bisection method; (2) maximum 4.3x speedup to a case of using conventional multi-section method; were obtained. | |||||||
