Green500 list: Two Swiss HPC systems in the top 10

The latest Green500 list ( has been released today at the SC12 supercomputing conference in Salt Lake City, USA. The purpose of the Green500 is to provide a ranking of the most energy-efficient supercomputers in the world.

Two HPC system installed in Switzerland are now ranked in the top 10:

  • Position 4: Todi Cray XK7 at CSCS with 2,121 MFLOPS/W
    Opteron 6272 16C 2.100GHz, Cray Gemini interconnect, NVIDIA Tesla K20 Kepler
  • Position 10: CADMOS BG/Q at EPFL with 2,101 MFLOPS/W
    BlueGene/Q, Power BQC 16C 1.600GHz, Custom Interconnect

The most efficient supercomputer being Beacon a Appro GreenBlade GB824M, Xeon E5-2670 8C 2.600GHz, Infiniband FDR, Intel Xeon Phi 5110P installed at the National Institute for Computational Sciences/University of Tennessee.
