parallel eigenvalue solving algorithm for symmetric real matrix

Hello everybody.

I'm stuck in finding a good parallel algorithm for solving big real symmetric matrices. So far everything I found was a lot slower when parallel computed than in linear case.

so can anybody give an algo (in general case or already paralleled) or a link to some info.
