While web services represent the critical set of services offered at scale, big data analytics is emerging as a preferred service to be colocated with cloud web services at a lower priority raising the need for off-the-shelf priority scheduling. In this paper we report on the perils of Linux priority scheduling tools when used to differentiate between such complex services. We demonstrate that simple priority scheduling utilities such as nice and ionice can result in dramatically erratic behavior. We provide a remedy by proposing an autonomic priority scheduling algorithm that adjusts its execution parameters based on on-line measurements of the current resource usage of critical applications. Detailed experimentation with a user-space prototype of the algorithm on a Linux system using popular benchmarks such as SPEC and TPC-W illustrate the robustness and versatility of the proposed technique, as it provides consistency to the expected performance of a high-priority application when running simultaneously with multiple low priority jobs.","PeriodicalId":385538,"journal":{"name":"2013 IEEE 21st International Symposium on Modelling, Analysis and Simulation of Computer and Telecommunication Systems","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130651136","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}

In HAS, several qualities of the same videos are made available in the network so that clients can choose the best quality that fits their bandwidth capacity. This has particular implications on caching strategies with respect to the viewing patterns and the switching behavior between video qualities. In this paper we present analysis of a real HAS dataset collected in France and provided by the country's largest mobile phone operator. Firstly, we analyse the viewing patterns of HAS contents and the distribution of the encoding bit rates requested by mobile clients. Secondly, we give an in-depth analysis of the switching pattern between video bit rates during a video session and assess the implication on the caching efficiency. We also model this switching based on empirical observations. Finally, we propose WA-LRU a new caching algorithm tailored for HAS contents and compare it to the standard LRU. Our evaluations demonstrate that WA-LRU performs better and achieves its goals.","PeriodicalId":385538,"journal":{"name":"2013 IEEE 21st International Symposium on Modelling, Analysis and Simulation of Computer and Telecommunication Systems","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131568931","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}

With the increasing popularity of I/O-intensive applications, however, the virtualized storage used in shared environments can easily become a bottleneck and cause performance and scalability issues. Performance modeling and evaluation techniques applied prior to system deployment help to avoid such issues. In current practice, however, virtualized storage and its effects on the overall system performance are often neglected or treated as a black-box. In this paper, we present a systematic I/O performance modeling approach for virtualized storage systems based on queueing theory. We first propose a general performance model building methodology. Then, we demonstrate our methodology creating I/O queueing models of a real-world representative environment based on IBM System z and IBM DS8700 server hardware. Finally, we present an in-depth evaluation of our models considering both interpolation and extrapolation scenarios as well as scenarios with multiple virtual machines. Overall, we effectively create performance models with less than 11% mean prediction error in the worst case and less than 5% prediction error on average.","PeriodicalId":385538,"journal":{"name":"2013 IEEE 21st International Symposium on Modelling, Analysis and Simulation of Computer and Telecommunication Systems","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134173010","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}

As the number of occurrences of such errors increases with the storage capacity, latent sector errors have become more prevalent in today's high capacity storage devices. Such errors are typically not detected until an attempt is made to read the affected sectors. When a latent sector error is detected, the redundant data corresponding to the affected sector is used to recover its data. However, if no such redundant data is available, then the data of the affected sector is irrecoverably lost from the storage system. Therefore, the reliability of data storage systems is affected by both the complete failure of storage nodes and the latent sector errors within them. In this article, closed-form expressions for the mean time to data loss (MTTDL) of erasure coded storage systems in the presence of latent errors are derived. The effect of latent errors on systems with various types of redundancy, data placement, and sector error probabilities is studied. For small latent sector error probabilities, it is shown that the MTTDL is reduced by a factor that is independent of the number of parities in the data redundancy scheme as well as the number of nodes in the system. However, for large latent sector error probabilities, the MTTDL is similar to that of a system using a data redundancy scheme with one parity less. The reduction of the MTTDL in the latter case is more pronounced than in the former one.","PeriodicalId":385538,"journal":{"name":"2013 IEEE 21st International Symposium on Modelling, Analysis and Simulation of Computer and Telecommunication Systems","volume":"143 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120886526","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}
