Seabees: CBMU 635

In this book of words and pictures is a compilation of the work, accomplishments, and activities of the Twenty-Sixth United States Naval Construction Battalion (Second Section) which on July 15, 1945, was redesignated Construction Battalion Maintenance Unit Six Hundred Thirty-Five. It is dedicated to each officer and man who gave his\u27 best for the one and only cause, and each can be justly proud of the part he played. The Staff wishes to extend its appreciation to each and every member of this Battalion who helped in procuring and compiling the necessary information, for without your moral support. interest. and actual aid this book would have been impossible. We sincerely hope that in years to come you will refer to this book often in remembrance of the part you and your comrades played in the achievement of the final victory.https://digicom.bpl.lib.me.us/ww_reg_his/1044/thumbnail.jp

"Hot" for Warm Water Cooling

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
