Ok, thank you. I installed the last version of SCALAPACK (2.0.2) but I have always the same problem. The spectrum of eigenvalues obtained with pzlahqr doesn't match fully with the one obtained in the scalar case with zgees (there are few eigenvalues found with pzlahqr that aren't correct). Moreover changing the dimension of blocking the spectrum changes slightly finding, however, any eigenvalues that are wrong. Can you help me?
