Each Camera is equipped with an adjustable zoom lens in order to improve the coverage redundancy formalised ask-coverage across all moving objects under two perspectives: i) learning the movement patterns of the objects captured by a reinforcement learning algorithm at an individual camera level, and ii) utilising a decentralised coordination strategy by enabling an inter-camera communication among the neighbours. Given the dynamic nature of the problem, the first contribution of the paper is to show how learning an environmental constraint such as the movement pattern of the objects leads to a dynamic zoom selection behaviour that significantly improves k-coverage across the network. In our second contribution we show that the speed of convergence of the learning approach can be improved by applying a knowledge-sharing scheme. This is achieved by employing an inter-camera communication strategy across the network. The results indicate that enabling a knowledge-sharing scheme retains the high performance of pure reinforcement learning approaches. It also leads to a considerably faster convergence to the maximum possible k-coverage in learning approaches across the majority of test scenarios.","PeriodicalId":368308,"journal":{"name":"2019 IEEE 4th International Workshops on Foundations and Applications of Self* Systems (FAS*W)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128621741","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 this paper, we argue that a SAS needs an infrastructure and capabilities to look at its own history to explain and reason why the system has reached its current state and exhibits its current behaviour. Achieving this is no simple feat: there are different challenges with respect to the feasibility of storing past system history, querying it and applying the information in the context of a given decision-making algorithm. We introduce 4 levels of capabilities that should be exposed by reflective, self aware and self-adaptive systems, and which will guide our future research on the topic in the longer term. We demonstrate our results for the first two levels using temporal graph-based models. Specifically, we explain how the first level covers forensic analysis of the execution results. This is followed by the description of our results in enabling historical analyses while the self-adaptive system is running, based on the capabilities provided by the second level. Required system architectures are also proposed, as well as the overheads that would be imposed by live analysis. Research opportunities provided by the set of levels are also discussed.","PeriodicalId":368308,"journal":{"name":"2019 IEEE 4th International Workshops on Foundations and Applications of Self* Systems (FAS*W)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132139306","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}

To this end, we developed a benchmark automation tool and selected five Intel and AMD systems. We also chose three key benchmarks, namely STREAM, High-Performance Linpack (HPL), and High-Performance Conjugate Gradient (HPCG), to evaluate the memory, CPU, and aggregate performance. In the STREAM experiment, the high-bandwidth memory (MCDRAM) performance of the KNL was reduced by more than 50% at a specific point owing to the accuracy of the input array size which can be ignored in DDR memory. In the HPL experiment, KNL using MCDRAM exhibited the best optimization performance, but in the experiment without optimization, the performance of MCDRAM was rather lower than DDR or cache. Thus, MCDRAM code optimization may be required to utilize MCDRAM at peak performance in the many-core environment. In the HPCG experiment, the performance variance was large depending on the combination of the MPI process and the number of shared threads. When the number of MPI processes is set to 2 or 4 and the total number of shared threads is equal to the number of physical cores in the system, excellent performance was obtained. Moreover, the maximum performance of each single system was proportional to the memory performance.","PeriodicalId":368308,"journal":{"name":"2019 IEEE 4th International Workshops on Foundations and Applications of Self* Systems (FAS*W)","volume":"110 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114507758","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}
