【Abstract】 A new fast parallel algorithm for tridiagonal Toeplitz equations is presented which extends the solution space of LUO zhi-gang, et al. The theoretical analyses and numerical experiments on distributed-memory multicomputers have proved that its speedup is approximate to linearity. Experiments also show that the new algorithm has a high parallel efficiency.更多还原
