An administrator uses a utility function to define a set of power and performance objectives. Rather than creating a central controller to manage performance and power simultaneously, we use two existing IBM products, one that manages performance and one that manages power by controlling clock frequency. We demonstrate that, with good architectural and algorithmic choices established through trial and error, the two managers can indeed work together to act in accordance with a flexible set of power-performance objectives and tradeoffs, resulting in power savings of approximately 10%. Key elements of our approach include (a) a feedback controller that establishes a power cap (a limit on consumed power) by manipulating clock frequency and (b) reinforcement learning, which adoptively learns models of the dependence of performance and power consumption on workload intensity and the powercap.","PeriodicalId":179923,"journal":{"name":"Fourth International Conference on Autonomic Computing (ICAC'07)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122895076","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Large-scale spammers target commerce queries that they can monetize and attempt to spam as many top search results of those queries as possible. We model the large-scale search spam problem as that of defending against correlated attacks on search rankings across multiple keywords, and propose an autonomic anti-spam approach based on self-monitoring and self- protection. In this new approach, search engines monitor and correlate their own search results of spammer-targeted keywords to detect large-scale spam attacks that have successfully bypassed their current anti-spam solutions. They then initiate self-protection through targeted patrol of spam-heavy domains, targeted hunting at the sources of successful spam, and strengthening of specific weakness in the ranking algorithms. We describe the strider search ranger system which implements this new approach, and focus on its use to defend against an important class of search spam - the redirection spam - as a demonstration of the general concept. We evaluate the system by testing it against actual search results and show that it can detect useful spam patterns and eliminate a significant amount of spam for all three major search engines.","PeriodicalId":179923,"journal":{"name":"Fourth International Conference on Autonomic Computing (ICAC'07)","volume":"189 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122814769","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mobility, however, requires dynamic management of these platforms' distributed resources, and such management can also be used to meet application quality requirements and prolong application lifetimes, the latter by best using available energy resources. This paper presents energy-aware mobile service overlays (MSOs), a set of mechanisms and associated policies for running mobile applications across multiple, cooperating machines while actively performing power management to extend system usability lifetimes. MSO policies manage energy consumption by (i) allocating application components to available nodes based upon their current energy capacities and resource availabilities, (ii) monitoring for, and responding to changes in energy and resource characteristics, and (iii) dynamically exploiting energy-performance tradeoffs in over provisioned situations. Coupled with mobility, such cooperation enables multiple mobile platforms to bring their joint resources to bear on complex application tasks, providing significant benefits to application lifetimes and performance. Evaluations of MSOs on a MANET computing testbed indicate an extension in system lifetime of up to 10% for an example application.","PeriodicalId":179923,"journal":{"name":"Fourth International Conference on Autonomic Computing (ICAC'07)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129743988","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since these applications are performance sensitive, effective models for dynamic resource provisioning and for delivering quality of service to these applications become critical. Workloads in such environments are characterized by client sessions of interdependent requests with changing transaction mix and load over time, making model adaptivity to the observed workload changes a critical requirement for model effectiveness. In this work, we apply a regression-based approximation of the CPU demand of client transactions on a given hardware. Then we use this approximation in an analytic model of a simple network of queues, each queue representing a tier, and show the approximation's effectiveness for modeling diverse workloads with a changing transaction mix over time. Using the TPC- W benchmark and its three different transaction mixes we investigate factors that impact the efficiency and accuracy of the proposed performance prediction models. Experimental results show that this regression-based approach provides a simple and powerful solution for efficient capacity planning and resource provisioning of multi-tier applications under changing workload conditions.","PeriodicalId":179923,"journal":{"name":"Fourth International Conference on Autonomic Computing (ICAC'07)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127137831","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
