@conference {reddi2010web, title = {Web Search Using Mobile Cores: Quantifying and Mitigating the Price of Efficiency}, booktitle = {International Symposium on Computer Architecture}, year = {2010}, abstract = {The commoditization of hardware, data center economies of scale, and Internet-scale workload growth all demand greater power efficiency to sustain scalability. Traditional enterprise workloads, which are typically memory and I/O bound, have been well served by chip multiprocessors comprising of small, power-efficient cores. Recent advances in mobile computing have led to modern small cores capable of delivering even better power efficiency. While these cores can deliver performance-per-Watt efficiency for data center workloads, small cores impact application quality-of-service robustness, and flexibility, as these workloads increasingly invoke computationally intensive kernels. These challenges constitute the price of efficiency. We quantify efficiency for an industry-strength online web search engine in production at both the microarchitecture- and system-level, evaluating search on server and mobile-class architectures using Xeon and Atom processors.Categories and Subject DescriptorsC.0 [Computer Systems Organization]: General{\textemdash}System architectures; C.4 [Computer Systems Organization]: Performance of Systems{\textemdash}Design studies, Reliability, availability, and serviceabilityGeneral TermsMeasurement, Experimentation, Performance}, url = {https://dl.acm.org/citation.cfm?doid=1816038.1816002}, author = {Reddi, Vijay Janapa and Lee, Benjamin and Chilimbi, Trishul and Vaid, Kushagra} }
