SUMMARY:Emissions and Energy Efficiency on Large-Scale High Performance Co
 mputing Facilities:  ARCHER2 UK National Supercomputing Service Case Study
DESCRIPTION:Adrian Jackson (University of Edinburgh) and Alan Simpson and 
 Andrew Turner (Edinburgh Parallel Computing Centre (EPCC))\n\nLarge superc
 omputing facilities are critical to research in many areas that impact on 
 decisions such as how to address the current climate emergency, including 
 renewable energy facility design and new battery technologies. However, th
 ese systems themselves are a source of large amounts of emissions due to t
 he embodied emissions associated with their construction and decommissioni
 ng; and the power consumption associated with running the facility. Recent
 ly, we have been analyzing the impact of a UK national HPC facility (ARCHE
 R2) in terms of energy and emissions. Based on this work, we have made cha
 nges to the operation of the service that give a saving of more than 20% i
 n power draw of the computational resources, with all application benchmar
 ks showing reduced power to solution. We describe our analysis and the cha
 nges made to the operation of the service to improve its energy efficiency
 , and thereby reduce its climate impacts.\n\nTag: Energy Efficiency, Green
