SUMMARY:Keys to Sustainable Leadership Supercomputing for 2025+:  Location
 , Power, and Flexibility
DESCRIPTION:Andrew A. Chien (University of Chicago, Argonne National Labor
 atory (ANL))\n\nLeadership Supercomputing increasingly requires considerat
 ion of sustainability (carbon-emissions) and power cost (Opex) beyond trad
 itional architecture, system software, and application concerns.  Power ex
 trapolation of Top 500 systems suggests that next generation leadership sy
 stems will approach ~100MW with even higher power levels beyond.\n\nThe pa
 st decade has shown available power supply as a real limit. With examples 
 of power restriction a reality in Japan, Germany, China, and the UK. These
  challenges affect cloud as well with numerous datacenter reductions stemm
 ing from power shortages. Further, power Opex of supercomputer systems hav
 e become a significant part of TCO/lifetime cost, limiting lifetime delive
 red capability. A concomitant problem as power consumption grows and clima
 te change accelerates is growing pressure to reduce operational carbon foo
 tprint.\n\nLeadership Supercomputing in the modern era (2025+) requires la
 rge quantities of green power and at low cost. How is this possible? We di
 scuss three dimensions that must be considered: \n\n1. Location: where sup
 ercomputing resources are shapes power opportunity, and thus system design
  and operation\n2. Power: dynamics of local power grid, both generation an
 d local competitive load dictate both power infrastructure design and how 
 systems should be operated and applications scheduled/managed\n3. Flexibil
 ity: the new challenge for operations and applications is flexibility in t
 he time, shape, and location of computing use\n\nWe will describe opportun
 ities that are the key the sustainable, leadership supercomputing in the m
 odern (2025+ era). These opportunities enable 90% reduction in power cost,
  even larger reductions in scope 2 carbon emissions, and the changes in bo
 th supercomputer design as well as facilities design and operation to achi
 eve. We are working with leaders in Japan and the US DOE to capture these 
 opportunities.\n\nTag: Energy Efficiency, Green Computing, Sustainability\
