We discuss a parallel preconditioner for the algebraic systems of equations arising from Newton-Raphson linearization and finite element (FE) discretization of stabilized formulation for the highly nonlinear Stokes equations. We compare SSOR/Jacobi and FSAI(1)/Jacobi preconditioners for the parallel MINRES accelerator implemented using C++/OpenMP. Results are presented for SGI Altix 3700 and IBM Power4 machines. As an example a simulation of the compression test of the rigid-viscoplastic material is shown.
