This is because the heat capacity of liquids is orders of magnitude larger than that of air and once heat has been transferred to a liquid, it can be removed from the datacenter efficiently. The transition from air to liquid-cooling is an inflection point providing an opportunity to work collectively to set standards for facilitating the energy and cost efficiency of liquid-cooled HPC facilities and systems. The vision is to use non-chilled water, to facilitate heat re-use and to build solutions that are more energy-efficient, more carbon-neutral and more cost-effective than their air-cooled predecessors. The Energy Efficient HPC Working Group is developing guidelines for warmer liquid-cooling temperatures in order to assist with procurement specifications, to design warmer temperature cooling systems and facility cooling systems. This report describes those guidelines. SUMMARY:"Hot" for Warm Water Cooling PRIORITY:3 END:VEVENT END:VCALENDAR
