A Study on Query Energy Consumption in Web Search Engines

Matteo Catena, Nicola Tonellotto
2015 Italian Information Retrieval Workshop  
Therefore, in this study we experimentally analyze energy consumption on a per query basis.  ...  Commercial web search engines are usually deployed on data centers, which leverage thousands of servers to efficiently answer queries on a large scale.  ...  In line with such research agenda, in this work we evaluate the query energy consumption, i.e., the energy consumed by a search server to solve a single query.  ...

FindAll

Aruna Balasubramanian, Niranjan Balasubramanian, Samuel J. Huston, Donald Metzler, David J. Wetherall
2012 Proceedings of the 8th international conference on Emerging networking experiments and technologies - CoNEXT '12  
The key challenge in FindAll is in designing a search engine, which is both memory-and energy-intensive, on the constrained phone environment.  ...  We present the design and evaluation of FindAll, a local search engine that lets users search and retrieve web pages, even in the absence of connectivity.  ...  We thank all the participants of our user study who helped us collect data. This work was supported in part by an NSF Computing Innovation Fellowship and NSF grant CNS-1217644.  ...

Roi Blanco, Matteo Catena, Nicola Tonellotto
2016 Proceedings of the 25th International Conference on World Wide Web - WWW '16  
We propose a mathematical model to minimize the operational costs of multi-center Web search engines by exploiting renewable energies whenever available at different locations.  ...  In this paper, we tackle the problem of targeting the usage of green energy to minimize the expenditure of running multi-center Web search engines, i.e., systems composed by multiple, geographically remote  ...  ACKNOWLEDGEMENTS We would like to thank Ana Freire for her useful comments and help in the early stages of this paper.  ...

Energy-price-driven query processing in multi-center web search engines

Enver Kayaaslan, B. Barla Cambazoglu, Roi Blanco, Flavio P. Junqueira, Cevdet Aykanat
2011 Proceedings of the 34th international ACM SIGIR conference on Research and development in Information - SIGIR '11  
For largescale web search engines, this translates into high energy consumption and a huge electric bill.  ...  Based on the observation that energy prices and query workloads show high spatio-temporal variation, we propose a technique that dynamically shifts the query workload of a search engine between its data  ...  We discuss the energy-price-driven query processing problem in the context of multi-center web search engines.  ...

A self-adapting latency/power tradeoff model for replicated search engines

Ana Freire, Craig Macdonald, Nicola Tonellotto, Iadh Ounis, Fidel Cacheda
2014 Proceedings of the 7th ACM international conference on Web search and data mining - WSDM '14  
The model bases its decisions on examining the current and historical query loads of the search engine.  ...  Thorough experiments are conducted to validate the usefulness of the proposed adaptive model using historical Web search traffic submitted to a commercial search engine.  ...  Hence, the typical approach taken by Web search engines is to deploy a distributed search architecture relying on a very large data centre to deal with the worst-case query volumes [13] .  ...

Efficient Energy Management in Distributed Web Search

Matteo Catena, Ophir Frieder, Nicola Tonellotto
2018 Proceedings of the 27th ACM International Conference on Information and Knowledge Management - CIKM '18  
Distributed Web search engines (WSEs) require warehouse-scale computers to deal with the ever-increasing size of the Web and the large amount of user queries they daily receive.  ...  The energy consumption of this infrastructure has a major impact on the economic profitability of WSEs. Recently several approaches to reduce the energy consumption of WSEs have been proposed.  ...  We thank Stefano Ceccotti for his help in the early stages of this work.  ...

Modeling successful performance in Web searching

Anne Aula, Klaus Nordhausen
2006 Journal of the American Society for Information Science and Technology  
Several previous studies have measured differences in information search success of novices and experts.  ...  Instead of dividing the searchers into different groups based on their expertise, we chose to model search success with Task Completion Speed, TCS.  ...  In reality, a query with multiple terms is likely to be more along these lines: 'energy consumption sports food contents' (a real query by Participant 6).  ...
