Abstract
We discuss a parallel implementation of the domain decomposition method bas ed on the macro-hybrid formulation of a second order elliptic equation and on an approximation by the mortar element method. The discretization leads tc, an algebraic saddle-point problem. An iterative method with a block-dia gonal preconditioner is used far solving the saddle-point problem. A parall el implementation of the method is emphasized. Finally the results of numer ical experiments are presented.
