Does anyone know of any recent progress on parallel eigensolvers suitable for 
beowulf clusters running over gigabit ethernet?

 It would be nice to have something that scaled moderately well and at least 
gave reasonable approximations to some subset of eigenvalues and vectors for 
large (10,000x10,000) symmetric systems.

My interests are primarily for quantum chemistry.

It's pretty obvious that you can compute eigenvectors in parallel after you 
get the eigenvalues but it would be nice to get eigenvalues mostly in 
parallel requiring maybe just a couple of serial iterates ...
