A new implementation of the BDDC method is presented based on a global formulation without an explicit coarse problem, with massive parallelism provided by a multifrontal solver. Constraints are implemented by a projection and sparsity of the projected operator is preserved by a generalized change of variables. The effectiveness of the method is illustrated on several engineering problems." . "10.1016/j.matcom.2011.03.014" . "RIV/61388998:_____/12:00379792!RIV13-AV0-61388998" .
