parallel iterative algorithms for solving Linear System of Equations

Does someone know any library or ready source code of parallel implementation of quick iterative methods (bicgstab, CG, etc) for solving Linear System of Equations for example using MPI or OpenMP?

Chapter 7 of Parallel Programming for Multicore and Cluster Systems contains algorithms for systems of linear equations, with source code (MPI).

PetSC is a good example (both serial and MPI, and with a large library of linear and nonlinear solvers either included or provided as interfaces to external libraries). Trillinos is another example, but it's a much broader project and not as nicely integrated as PetSC. Aztec has a number of solvers, as does Hypre, which is hybrid (MPI+OpenMP).

These are all MPI-based at least in part; I don't know of too many OpenMP-enabled ones, although google suggests Lis, which I'm not familiar with.
