[petsc-users] superlu_dist output

[Gideon Simpson]

This is the macports version.  For me, this appears when running a problem with a linear solver with the flags

-pc_factor_mat_solver_package superlu_dist -pc_type lu

Nothing else is required.  The answer it gives is correct, I’d just like to suppress the output.
