We propose an operating system (OS) and programming interface to place data from within the user application. We present a profiling tool to help programmers decide on the placement of application data in hybrid memory systems. Cycle-accurate simulation of modified applications confirms that our approach is more energy-efficient than state-of-the-art hardware or OS approaches at equivalent performance. Moreover, our results are validated on several candidate NVM technologies and a wide set of 14 benchmarks. The key observation behind this work is that, for the workloads we evaluated, application objects are too short-lived to motivate migration. Utilizing this property significantly reduces the hardware complexity of hybrid memory systems.","PeriodicalId":417279,"journal":{"name":"Proceedings of the 12th ACM International Conference on Computing Frontiers","volume":"312 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124290491","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}

Leading practitioners of Big Data analytics have already moved past the stage of using single analytics modalities on siloed data sources. They are starting to create composite analytics solutions that take advantage of multiple analytics programming models and are also integrating them into their existing enterprise IT systems. At the same time, the CIOs have wholeheartedly embraced cloud computing as a means of reducing the capital and operational cost of their IT systems and streamlining their DevOps processes. Platform-as-a-Service (PaaS) as a cloud computing consumption model has seen wide acceptance by developers and IT administrators. Although there are PaaS platforms for individual workload types involved in these advanced composite analytics solutions, the composition aspect is not addressed by any of these individual PaaS platforms. Further, there is no lifecycle management support for the solution as a single logical entity. This paper argues for the need of a true PaaS for composite analytics solutions in order to accelerate their adoption by the industry and foster the creation of a healthy ecosystem. We present the design and prototype implementation of such a platform and our early experience of using it to deploy a Telco Fraud Detection solution.","PeriodicalId":417279,"journal":{"name":"Proceedings of the 12th ACM International Conference on Computing Frontiers","volume":"47-48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114468531","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}

Among the on-chip components, the cores and caches consume most of the power. We observe that parallel programs exhibit different scalability characteristics with respect to the number of cores and the size of caches. Running programs with fewer cores or smaller caches does not always degrade performance significantly. Based on these observations, we propose a scheme, called TaPEr, that can dynamically (1) predict the scalability of parallel programs with respect to core count and cache capacity; (2) re-allocate available power to cores or caches based on a program's scalability in order to satisfy the power constraints; and (3) achieve high performance (comparing with DVFS or simple shutdown schemes) at the same time.","PeriodicalId":417279,"journal":{"name":"Proceedings of the 12th ACM International Conference on Computing Frontiers","volume":"40 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122427573","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}

Moving Target IPv6 Defense (MT6D) promises security by letting nodes hop to new addresses that are cryptographically computed between involved nodes without disrupting ongoing conversations. After implementing MT6D as a testbed for previous research project, we asked ourselves if it is worth looking at the old addresses that are being given up by MT6D nodes and purged in the process. We explored the idea if activity on these relinquished addresses holds any vital clues for verifying and reinforcing the security of MT6D networks. During the analysis, we realized the need for a method to ensure the resiliency of the scheme besides uncovering any attacks that are underway. In this paper, we will discuss a novel solution that comprises of learning addresses that are being relinquished by the MT6D nodes, acquiring these addresses, performing traffic enumeration on these addresses and visualizing the same. We can become cognizant of a trailing attacker following a MT6D node along the address changes, besides uncovering any suspicious traffic hitting the MT6D nodes with this solution in place.","PeriodicalId":417279,"journal":{"name":"Proceedings of the 12th ACM International Conference on Computing Frontiers","volume":"138 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127452710","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}

Cloud Patterns can be seen as an evolution of classic Design Patterns, since they provide optimal solutions for software development specialized for Cloud environments. By mapping Design and Cloud Patterns elements, we think it would be possible to develop an approach to support the porting of legacy applications to the Cloud, thus easing the modernization process and laying the basis for an interoperability and portability friendly software development. Here we analyse the actual feasibility of the mapping between Design and Cloud Patterns, by proposing a simple score-based methodology which analyses characteristics of both pattern categories to propose a solution to the matching problem. In order to compare different categories of patterns we leverage a semantic based representation, defined in previous works, which describes a set of common relevant characteristics related to patterns' scope and objectives.","PeriodicalId":417279,"journal":{"name":"Proceedings of the 12th ACM International Conference on Computing Frontiers","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122821665","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}

Software-managed hybrid memory is a promising way to incorporate NVM in main memory due to its architectural simplicity. However, there are significant performance issues caused by interference in the memory system due to data migration between DRAM and NVM and a lack of effective migration policies. We propose new analysis and simulation techniques to understand the behavior of software-managed hybrid memory. These techniques allow us to characterize the overhead experienced by requests in the memory hierarchy and identify the factors that limit performance in software-managed hybrid memory. We show that queuing delays at the NVM banks and NVM bus are the main limiting factors.","PeriodicalId":417279,"journal":{"name":"Proceedings of the 12th ACM International Conference on Computing Frontiers","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123006211","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}

Cloud computing unburdens them from running and maintaining their compute resources, whereas analytic applications comb through their big data to provide new insights for a competitive advantage in the market. Analytic applications are carefully tailored to their target problems. While there is a lot of work published on both the mechanics of cloud computing as well as analytic methods for distilling insights from a variety of data, there is little work available about the cloud influence on the analytics platforms which aim at lowering the barrier for the creation, deployment, scaling and maintenance of next generation analytic workloads.
