Just build in master with --with-openmp --download-hypre then at runtime make sure you set the damn OpenMP environmental variable to the number of OpenMP threads you want to use (Best interface design EVER!). Report problems to petsc-maint. Similar quality interface for SuperLU_Dist and presumably for MKL-AIJ matrices.

I think we would be interested in testing the new MKL-AIJ matrix but as I understand it we are waiting on the Mat-Mat Mult method(s) to get migrated. I should have at least one user that would be interested in testing this when it is ready.
