 +======Green System Design: Beyond Operational Energy to Sustainability======

 +"​Green"​ system design (whether at the server or datacenter scale)
 +requires a focus on environmental sustainability. Prior studies have
 +focused on operational energy consumption as a proxy for
 +sustainability,​ but this metric only captures part of the
 +environmental impact--specifically,​ only the system'​s impact during
 +its operation. This talk proposes that to understand a system'​s total
 +impact on environmental sustainability,​ one needs to examine the
 +entire lifecycle of a system, beyond operational energy to also
 +include material extraction, manufacture,​ transportation,​ and
 +recycling. ​ The talk will focus on the two main contributions of this
 +work:  First, we proposed a methodology that allows such a lifecycle
 +analysis, specifically providing attribution of sustainability
 +bottlenecks to individual system architecture components such as CPU,
 +DRAM, disk, etc.; second, using this methodology,​ we compared the
 +sustainability tradeoffs between popular energy-efficiency
 +optimizations--energy proportionality,​ server consolidation,​ and
 +low-power embedded hardware (MicroBlades)--across a wide workload
 +space. ​ The talk provides proof that energy-efficiency does not
 +necessarily enable sustainability. ​ Finally, I'll discuss the
 +sustainability bottlenecks and optimizations for future system designs
 +along with some of the current work surrounding system co-designed
 +between architecture,​ packaging and cooling.
 +Justin Meza is a graduate student at Carnegie Mellon University in
 +Pittsburgh, Pennsylvania pursuing his Ph.D. in Electrical and Computer
 +Engineering,​ advised by Onur Mutlu. ​ He received his B.S. at
 +University of California at Los Angeles in Computer Science.
 +He also works in the Exascale Computing Lab at Hewlett-Packard
 +Laboratories in Palo Alto, California performing research regarding
 +energy-efficiency metrics and sustainability practices in computing
 +platforms from handhelds to datacenters.
