Big Blue's supercomputers are among the greenest in the world. The June Green500 list, published by, showed that 18 of the top 20 greenest supercomputers in the world are made by IBM. The most energy-efficient system was an IBM supercomputer based on an IBM BladeCenter QS22 located in Poland at the Interdisciplinary Center for Mathematical and Computational Modeling at the University of Warsaw. The computer produces more than 536 Mflops (millions of floating point operations per second) per watt of energy.

The world's fastest supercomputer, the IBM supercomputer at Los Alamos National Laboratories, came in fourth for energy efficiency, producing over 444 Mflops per watt of energy.
