SUMMARY:Operational Efficiency Successes and Challenges for High Performan
 ce Computing at Los Alamos National Lab
DESCRIPTION:Genna Waldvogel (Los Alamos National Laboratory)\n\nLos Alamos
  National Laboratory has experience operating advanced high performance co
 mputing facilities since the late 1950s. Today, the computing facilities u
 se about 50% of the lab’s total energy and 31% of it’s total water. The ne
 ed for efficient water and energy usage is ongoing to support growth and e
 xpanded mission. Data-driven engineering, innovations and strategic planni
 ng are the lab's toolkit for both its external challenges and its internal
  processes. \nWe present the history of the resource restrictions, water r
 euse, carbon-free power procurement and computing optimizations with the f
 ollowing accomplishments:  \nHigh-performance computing facilities now use
  almost 100% of reclaimed water instead of potable, reducing our water usa
 ge almost to zero.  \nLANL has signed a contract to purchase and use 170MW
  of solar power from a new solar farm in the northwest corner of the state
 , enabling mission expansion using a renewable energy source. \nCurrent ef
 forts include the application of machine learning models to accurately pre
 dict short-term energy needs, enabling more informed and diverse energy pr
 ocurement strategies. \nWhile we have made great strides there is still mo
 re to do and some of our plans for the future include a central utility pl
 ant and to determine ways to reuse waste heat.\n\nDomain: Engineering, Lif
 e Sciences, Physics, Computational Methods and Applied Mathematics\n\nSess
 ion Chair: Denisa-Andreea Constantinescu (EPFL)\n\n
