The RAS preconditioning on academic and industrial problems. To build the Aitken's acceleration, a choice of an orthogonal basis defined on the subdomains interfaces must be made. For saving computational time, an orthogonal basis dependent of the problem is made using the singular values decomposition technique. The parallel implementation of the method in the Petsc framework is described.
