Huge sparse matrix - vector multiplication

Question

I'm looking for a library to do huge Sparse Matrix x Vector multiplication. The matrix itself will almost fill the RAM.

I've found Eigen3, OSKI and some basic Sparse BLAS implementations.

Are there other options? How can I choose between them ?

Edit: There is also Intel's MKL

There are the linear algebra routines in Trilinos and Petsc. Also, most finite element libraries like deal.II or Dune have this capability.

Don't they use seom more low level library under the hood? – Łukasz Lew Sep 12 '13 at 14:30
Not necessarily. Trilinos and Petsc have their own parallel matrix structures. As for deal.II, it is your choice, whether you use their own structures or Trilinos, or Petsc – Guido Kanschat Sep 13 '13 at 06:37
