The impact of heavy energy users such as data centers and supercomputer facilities has led to a new way to rate supercomputer performance. Environmentally.
In recent years, growing concern about the environmental impact of heavy energy users such as data centers and supercomputer facilities has led to a new way to rate supercomputer performance – this time, in terms of a machine’s efficiency, expressed in terms of the number of operations performed per watt.
Established by a group of supercomputing industry professionals, the Green 500 bi-annual list ranks the world’s 500 most energy-efficient supercomputers.
Ultimately, the purpose of the Green 500 list is to encourage the development of supercomputers that are powerful enough to meet the needs of their particular applications, while decreasing the total cost of ownership through improved energy efficiency.
In the November 2014 Green 500 list, the Suiren supercomputer achieved second-place honors. 3M™ Novec™ Liquid immersion cooling played a key role in achieving this high energy efficiency rating. The construction of the Suiren is based on the ExaScaler-1 component, consisting of 32 units in 4 submersion tanks. The machine is cooled by a single-phase immersion cooling system and employs 3M™ Fluorinert™ Electronic Liquid as the heat transfer medium.
