Petsc is really a superpackage providing many parallel linear solvers
(iterative, direct, preconditioners, ...) together with nonlinear
solvers, time steppers, etc. The solvers can be both petsc-native or
external packages, nevertheless all are accessed via a uniform
interface. IMHO UMFPACK is one of the optional external solvers petsc
can use, so to answer your question, petsc can do anything that UMFPACK
does and much more.
