Top500 List - June 2012

Rmax and Rpeak values are in TFlops. For more details about other fields, check the TOP500 description.

Rpeak values are calculated using the advertised clock rate of the CPU. For the efficiency of the systems you should take into account the Turbo CPU clock rate where it applies.

Rank Site System Cores Rmax (TFlop/s) Rpeak (TFlop/s) Power (kW)
