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 ...
Best regards to all
