At http://www.mcs.anl.gov/petsc/documentation/linearsolvertable.html  there are two listed. ./configure —download-hypre

mpiexec -n 23 ./yourprogram -pc_type hypre -pc_hypre_type ilupt or euclid   

you can also add -help to see what options are available.

  Both pretty much suck and I can’t image much reason for using them.
