DESCRIPTION;ENCODING=QUOTED-PRINTABLE:ABSTRACT: About half of an air-cooled data-center's energy consumption is wasted on powering the cooling systems that keep the computer system from overheating.  Furthermore, the amount of heat dissipated by future supercomputers limits the practicality of air-cooling. Liquid-cooling is key to reducing cooling energy consumption for future supercomputers because the heat capacity and transfer efficiency of liquids is orders of magnitude greater than that of air.=0A  =0AThe transition from air to liquid-cooling is a technology inflection point providing=0Aan opportunity to set guidelines for energy efficiency of liquid-cooled facilities and systems. Substituting vapor-compression refrigeration systems with cooling towers or dry coolers that provide warmer water to supercomputers is the natural progression towards energy conservation. The U.S. Department of Energy (DOE) Supercomputing Laboratories are working collaboratively with industry representatives to develop guidelines for warmer liquid-cooling temperatures to guide future supercomputer procurements, and to facilitate the design of warmer temperature cooling systems.
