Parallel direct solver package for LU factorization Use ./configure --download-superlu_dist --download-parmetis --download-metis --download-ptscotch to have PETSc installed with SuperLU_DIST
<P>
Use -pc_type lu -pc_factor_mat_solver_type superlu_dist to use this direct solver
<P>
Works with AIJ matrices
