Cooling the World's Largest ARM Supercomputer
Astra, the ARM-based supercomputer Hewlett Packard Enterprise is building for the US Department of Energy, will be using an unusual cooling design for a supercomputer
• The data center will be designed to use indirect liquid cooling, meaning the servers will be air-cooled, but the air will be cooled by a liquid-based cooling loop
• Despite this, the data center is expected to be highly energy efficient, designed to get the LEED Gold rating
• Astra is being developed as part of the DOE’s Vanguard program, whose goal is to advance new computing architectures in support of a mandate to secure the nation’s nuclear stockpile
