This paper presents a divide and conquer algorithm for solving the eigenvalue prob-lem of real symmetric band matrices. The new algorithm bases on homotopy con-tinuation, including inverse power iteration and inverse subspace iteration with *** results show that our algorithm is strongly competitive with the known algo-rithms in speed. Above all, our algorithm is well suitable for parallel *** results of parallel computing are also presented in this paper.
