A block version of the divide and conquer algorithm of \textit{J. J. M. Cuppen} [Numer. Math. 36, 177-195 (1981; Zbl 0431.65022)] for the symmetric eigenvalue problem is derived. Tests on a shared memory computer are reported, where the new algorithm is compared to the bandwidth reduction and full matrix algorithms of EISPACK.
