During recent years, heterogeneous HPC systems, which combine commodity processors with GPUs have proven to deliver superior energy efficiency. In this paper an international collaboration of research groups from Germany and Saudi Arabia presents SANAM, the prototype of a general-purpose 10 PFLOPS supercomputer based on off-the-shelf components. Leveraging an advanced multi-GPU architecture, supported by particular software optimizations that aim at energy efficiency, the system ranked second in the Green500 list of November 2012 with a power efficiency of 2351 MFLOPS/W.
