Yet, the problem of identifying faulty configuration remains at large. Current approaches for fault identification are focused on event correlation techniques which suffer from limited granular data generated by software components. As complexity of cloud environments increase, resource sharing increases many-fold thereby making it even harder to isolate configuration faults through analysis of events. In this paper, we propose a scalable approach that not only identifies the presence of a configuration fault but also attempts to nail down the parameter that is the source of the observed fault. We leverage the knowledge of shared resources in the environment and use a simple matrix representation for providing near real-time analysis of the faults. This enables the solution to be used for both reactive management and for automated proactive problem determination. Experiments through simulations demonstrate that our approach is effective in identifying configuration faults with reduced time and increased accuracy. Our algorithm gracefully handles the complexity of the problem as the system size grows.","PeriodicalId":430420,"journal":{"name":"ACM International Conference on Computing Frontiers","volume":"1 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120971785","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}

Current devices, however, are plagued by problems of yield, and durability. We present a limit study of an aggressive neural network application that has a high update rate and a strict latency requirement, analog neural branch predictor. Of course, traditional analog neural network (ANN) implementations of branch predictors are not built with the idea that the underlying bits are likely to fail due to both manufacturing and wear-out issues. Without some careful precautions, a direct one-to-one replacement will result in poor behavior.\u0000 We propose a hybrid system that uses SRAM front-end cache, and a distributed-sum scheme to overcome memristors' limitations. Our design can leverage devices with even modest durability (surviving only hours of continuous switching) to provide a system lasting 5 or more years of continuous operation. In addition, these schemes allow for a fault-tolerant design as well. We find that, while a neural predictor benefits from larger density, current technology parameters do not allow high dense, energy-efficient design. Thus, we discuss a range of plausible memristor characteristics that would; as the technology advances; make them practical for our application.","PeriodicalId":430420,"journal":{"name":"ACM International Conference on Computing Frontiers","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124757187","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}

Such complexity is escalated with variations in workload behaviors. In an effort to support a dynamic, adaptive and scalable operating system (OS) scheduling policy for MMMP, architectural strategies are proposed to construct linear models to capture workload behaviors and then schedule threads according to their resource demands. This paper describes the design through three steps: in the first step we convert a static scheduling policy into a dynamic one, which evaluates the thread mapping pattern at runtime. In the second step we employ regression models to ensure that the scheduling policy is capable of responding to the changing behaviors of threads during execution. In the final step we limit the overhead of the proposed policy by adopting a heuristic approach, thus ensure the scalability with the exponential growth of core and thread counts. The experimental results validate our proposed model in terms of throughput, adaptability and scalability. Compared with the baseline static approach, our phase-triggered scheduling policy could achieve up to 29% speedup. We also provide detailed tradeoff study between performance and overhead that system architects can reference to when target systems and specific overheads are presented.","PeriodicalId":430420,"journal":{"name":"ACM International Conference on Computing Frontiers","volume":"1655 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129314160","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}

Every company worldwide must ensure a proper compliance level with current and future laws and regulations, but managing the dynamic nature of the regulatory environment is a challenge, for both small and medium business as well as large corporations. Specifically the challenge is knowing and interpreting which regulations impact a particular business. Governments and standard bodies keep producing new, revised legislation, and businesses today rely on employees and consultants for tracking and understanding impact on their operations.\u0000 This paper introduces a novel prototype solution that addresses these concerns through the use of advanced text analytics. In particular the system is able to discover sources of regulatory content on the world wide web, track the changes to these regulations, extract metadata and semantic information and use these to provide a semantically guided comparison of regulation versions. Moreover, by leveraging the IBM DeepQA architecture, the solution is able to cross reference business objectives with the regulatory database and provide insights about the impact of new and revised laws on a company's business.","PeriodicalId":430420,"journal":{"name":"ACM International Conference on Computing Frontiers","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121442077","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}
