SCALABILITY OF DOMAIN DECOMPOSITION METHODS
Brož J., Kruis J.
pages 32 - +18p., full text

Scalability of the FETI method depends on applied preconditioner. There are two basic preconditioners for the FETI method – the Dirichlet preconditioner and the lumped preconditioner. The Dirichlet preconditioner is mathematically optimal but its time requirements are greater than requirements of the lumped preconditioner. This paper deals with implementation of the lumped preconditioner into an open source computer code. The implementation is based on the MPI library and is intended for parallel processing. Behaviour of the FETI method is shown on several two dimensional and three dimensional numerical examples. The test have been computed on a cluster of PCs.
