Recognizing the unsustainability in designing power hungry HPC systems, in the recent years an effort towards an energy and performance efficient HPC design is on the rise. Based on the available data on top green HPC systems, in this paper we analyze the main components of the HPC system with the attempt to provide an insight into the green efficiency in line with the technology development. Using global scale measurements, our goal is to discover the most promising designs and pinpoint on the existing main challenges that should direct future research efforts.
