Ok. Just so that I understand your point: you are saying that because petsc (and other advanced direct solvers) will calculate a new ordering for the matrix factorization, it does not help to calculate it in advance. However, for a more basic direct solver, which does not calculate the reordering as a part of its factorization, it may be beneficial to calculate this reordering in advance. correct?
