Tianhe-1A with a peak performance of 4.701 PetaFLOPS Nit: Linpack is an astoundingly easy benchmark to optimize, and they only attained 2.57 Pflop/s there. Most real science runs at much lower efficiency than Linpack (often more than an order of magnitude), primarily due to architectural reasons, so the theoretical peak number is even less meaningful than Linpack.
