We present a new parallel algorithm for the exact diagonalization of the t -t'-Hubbard model with the Lanczos method. By invoking a new scheme of labeling the states we were able to obtain a speedup of up to four on 16 nodes of an IBM SP2 for the calculation of the ground state energy and an almost
