DESCRIPTION;ENCODING=QUOTED-PRINTABLE:ABSTRACT: We describe an implementation and scalability results of a hybrid FETI (Finite Element Tearing and Interconnecting) solver based on our variant of the FETI type domain decomposition method called Total FETI. In our approach a small=0Anumber of neighboring subdomains is aggregated into clusters, which results into a smaller coarse problem. Current implementation of the solver is focused on the optimal performance of the main CG solver, including: implementation of  ommunication hiding and avoiding techniques for global communications; optimization of the nearest neighbor communication - multiplication with global gluing matrix; and optimization of the parallel CG algorithm to iterate over local Lagrange multipliers only. The performance is demonstrated on a linear elasticity synthetic 3D cube and real world benchmarks.
