      One of the biggest challenges in high-performance computing is to reduce the power and energy consumption. Research in energy efficiency has focused mainly on energy consumption at the node level. Less attention has been ...
    • Software-managed power reduction in Infiniband links 

      Dickov, Branimir; Pericas, Miquel; Carpenter, Paul; Navarro, Nacho; Ayguadé Parra, Eduard (Institute of Electrical and Electronics Engineers (IEEE), 2014)
      Conference report
      Open Access
      The backbone of a large-scale supercomputer is the interconnection network. As compute nodes become more energy-efficient, the interconnect is accounting for an increasing proportion of the total system energy consumption. ...
