QPACE, the supercomputer at Research Center Jülich and the University of Wuppertal, is now deemed the world's most energy efficient supercomputer on the Green500 List.
The Green500 List ranks the energy efficiency of supercomputers around the world.
To quote: "The QPACEs Intel PowerXCell processors are an enhancement of the Cell/B.E. processor, originally developed by Sony, Toshiba and IBM for Sony's PlayStation 3 console.
QPACE (Quantum chromodynamics Parallel Computing on the Cell) is being used to simulate forces in elementary particle physics, especially in the research area of quantum chromodynamics, which describes such things as how a proton is made up out of quarks and gluons.
It consists of four racks at Research Center Jülich and four at the University of Wuppertal. Each of the QPACE installations has a top performance of 100 TeraFlops, equal to 100 trillion floating point operations per second. The supercomputer runs a standard Fedora Linux distro OS.
Each rack in QPACE contains 256 IBM PowerXCell 8i nine-core processors and 1 Terabyte storage, and uses 30 kilowatts of power."
