With SLEPc you can reliably compute up to a few thousand eigenpairs of a huge matrix. This is sufficient for most applications. We are working for optimizing memory usage in the case that many eigenpairs are requested. Have a look at http://www.grycap.upv.es/slepc and if you need more details, contact us at slepc-maint at grycap.upv.es Jose
