ABSTRACT
We present a parallel algebraic preconditioner for the Schur complement system. This preconditioner aims to be a robust black box solver for commercial Finite Element packages. The preconditioner is based in a strongly dropped factorization of the Aii matrices. Two levels of parllelism are exploited using PVM and openMP. The preconditioner is tested with an scalar convection-diffusion equation, and a set of industrial test cases arising from the finite element package PERMAS and the Davis collection. The experimental results shown the robustness of it preconditioner, and it has a high scalability. We obtain quasi-linear spped-up until 32 processors.
