液体冷却是降低这一代超级计算机能耗的关键，并且在可预见的未来仍然是路线图上的内容。这是因为液体的热容量比空气的热容量大几个数量级，一旦热量传递到液体，就可以有效地从数据中心去除。从空气冷却到液体冷却的转变是一个转折点，提供了共同努力制定指导方针以促进液体冷却高性能计算 (HPC) 设施和系统的能源效率的机会。我们的愿景是使用基于非压缩机的冷却，以促进热量再利用，从而构建比其风冷前辈更节能、碳密集度更低且更具成本效益的解决方案。节能 HPC 工作组正在制定提高液体冷却温度的指南，以标准化设施和 HPC 设备，并为废热再利用提供更多机会。本报告描述了这些指南的制定过程。
Liquid cooling is key to reducing energy consumption for this generation of supercomputers and remains on the roadmap for the foreseeable future. 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 guidelines for facilitating the energy efficiency of liquid-cooled High Performance Computing (HPC) facilities and systems. The vision is to use non-compressor-based cooling, to facilitate heat re-use, and thereby build solutions that are more energy-efficient, less carbon intensive 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 standardize facility and HPC equipment, and provide more opportunity for reuse of waste heat. This report describes the development of those guidelines.
