Title
Improving the energy efficiencies of power supply and cooling facilities for 10 peta-scale supercomputer.
Abstract
We report our operational experience of improving the energy efficiency of the power supply and cooling facilities of the K computer. By optimizing the number of active air handlers, the blowout temperature and the number of fans, the power consumption of the air handlers was reduced by approximately 40 %. We next considered improvements to the energy efficiency of the gas turbine power generators. After analyzing the long-term power generation profile, we found that the efficiency of the gas turbine power generators could be improved by more than 50 %. To increase the energy efficiency of the cooling towers, we considered a range of ways of improving the ventilation around the cooling towers and finally decided to remove a section of wall panels from the chiller building. Preliminary results suggest that the modification has had a positive effect on efficiency.
