The description includes a new method with no overlap of subdomains and interfaces on the coarse grid. Implementation issues are discussed for all the methods and their comparison is made on a model elasticity problem. Special attention is given to nonsymmetric hybrid proconditioners. A parallel implementation of the additive Schwarz method is tested on a 3D elasticity problem, employing a Beowulf cluster."@en . "domain decomposition; Schwarz methods; coarse grid"@en .
