  ParPre This is an add-on package to Petsc; section 3.10. It is solely a collection of parallel preconditioners, to be used with iterative methods either from Petsc or coded by the user. The data structures are those used by Petsc.

ParPre can be used independently of Petsc, but does require Petsc to be installed.
