Dedicating high-end servers for executing scientific applications that run intermittently, such as severe weather detection or generalized weather forecasting, wastes resources. While the Infrastructure-as-a-Service (IaaS) model used by today's cloud platf...
Finding a
Found in: Distributed Computing Systems Workshops, International Conference on
By Ville Satopää, Jeannie Albrecht, David Irwin, Barath Raghavan
Issue Date:June 2011
pp. 166-171
Computer systems often reach a point at which the relative cost to increase some tunable parameter is no longer worth the corresponding performance benefit. These ``knees'' typically represent beneficial points that system designers have long selected to b...
Virtual Machine Hosting for Networked Clusters: Building the Foundations for
Found in: Virtualization Technology in Distributed Computing, International Workshop on
By Laura Grit, David Irwin, Aydan Yumerefendi, Jeff Chase
Issue Date:November 2006
pp. 7
Virtualization technology offers powerful resource management mechanisms, including performance-isolating resource schedulers, live migration, and suspend/resume. But how should networked virtual computing systems use these mechanisms? A grand challenge is...
Toward a Doctrine of Containment: Grid Hosting with Adaptive Resource Control
Found in: SC Conference
By Lavanya Ramakrishnan, Laura Grit, Adriana Iamnitchi, David Irwin, Aydan Yumerefendi, Jeff Chase
Issue Date:November 2006
pp. 20
Grid computing environments need secure resource control and predictable service quality in order to be sustainable. We propose a grid hosting model in which independent, selfcontained grid deployments run within isolated containers on shared resource prov...
Ensemble-level Power Management for Dense Blade Servers
Found in: Computer Architecture, International Symposium on
By Parthasarathy Ranganathan, Phil Leech, David Irwin, Jeffrey Chase
Issue Date:June 2006
pp. 66-77
One of the key challenges for high-density servers (e.g., blades) is the increased costs in addressing the power and heat density associated with compaction. Prior approaches have mainly focused on reducing the heat generated at the level of an individual ...
Here Today, Gone Tomorrow: Exploiting Transient Servers in Datacenters
Found in: IEEE Internet Computing
By Rahul Singh,Prateek Sharma,David Irwin,Prashant Shenoy,K.K. Ramakrishnan
Issue Date:July 2014
pp. 22-29
Distributed applications assume that datacenter servers are available unless they fail. Transient servers, which are available temporarily for an uncertain amount of time, are cheaper and more energy efficient than stable servers, which have continuous ava...
Combined heat and privacy: Preventing occupancy detection from smart meters
Found in: 2014 IEEE International Conference on Pervasive Computing and Communications (PerCom)
By Dong Chen,David Irwin,Prashant Shenoy,Jeannie Albrecht
Issue Date:March 2014
pp. 208-215
Electric utilities are rapidly deploying smart meters that record and transmit electricity usage in real-time. As prior research shows, smart meter data indirectly leaks sensitive, and potentially valuable, information about a home's activities. An importa...
Non-Intrusive Occupancy Monitoring using Smart Meters
Found in: Proceedings of the 5th ACM Workshop on Embedded Systems For Energy-Efficient Buildings (BuildSys'13)
By David Irwin, Dong Chen, Prashant Shenoy, Adarsh Subbaswamy, Sean Barker
Issue Date:November 2013
pp. 1-8
Detailed information about a home's occupancy is necessary to implement many advanced energy-efficiency optimizations. However, monitoring occupancy directly is intrusive, typically requiring the deployment of multiple environmental sensors, e.g., motion, ...
Incentivizing Advanced Load Scheduling in Smart Homes
Found in: Proceedings of the 5th ACM Workshop on Embedded Systems For Energy-Efficient Buildings (BuildSys'13)
By Prashant Shenoy, Ye Xu, David Irwin
Issue Date:November 2013
pp. 1-8
In recent years, researchers have proposed numerous advanced load scheduling algorithms for smart homes with the goal of reducing the grid's peak power usage. In parallel, utilities have introduced variable rate pricing plans to incentivize residential con...
GreenCache: augmenting off-the-grid cellular towers with multimedia caches
Found in: Proceedings of the 4th ACM Multimedia Systems Conference (MMSys '13)
By David Irwin, Dilip Kumar Krishnappa, Michael Zink, Navin Sharma, Prashant Shenoy
Issue Date:February 2013
pp. 271-280
The growth of smartphones combined with advances in mobile networking have revolutionized the way people consume multimedia data. In particular, users in developing countries primarily rely on smartphones since they often do not have access to more powerfu...
