In order to estimate cache line reuse, we assume that a sequence of cache line addresses can be treated randomly as characters in an arbitrary language such as proposed by the Information Theory. In this theory, the occurrence of each character previously occurred in a message composed by a sequence of characters can be used as a measurement of information - named entropy. The computation of the entropy of a program working set helps to estimate the chances of line reuse. We propose Adapted Discrete-based Entropy Algorithm (ADEA), a novel cache line replacement inspired by the Information Entropy which measures the discrete entropy by capturing the referential locality of programs by estimating the chances of cache line reuse. Furthermore, ADEA presents functions that control the essency and recency of memory access to avoid cache pinning. We present ADEA circuit complexity and show that it is comparable to other implementations. By modeling and evaluating ADEA using Simple Scalar for an L2 cache of an OOO processor, results show that ADEA's miss rate is up to 60% lower than LRU and 36% compared to adaptive policies Least Recently Used Insertion Policy (LIP) and Bimodal Insertion Policy (BIP). Furthermore, the use of ADEA's decay functions improves its miss rates up to 46% by avoiding pinning.","PeriodicalId":428764,"journal":{"name":"2012 International Conference on High Performance Computing & Simulation (HPCS)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130430533","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}

Some Platform-as-a-Service (PaaS) solutions fail to meet the security requirements of developers, administrators, and final users in a satisfactory and flexible manner. While some providers do offer secure cloud solutions, users are obliged to redesign and adapt their applications in order to conform to the provided environment. The present work introduces MagosCloud Secure, a highly-scalable, opportunistic, declarative, and secure solution constructed on the basis of MagosCloud[1], designed to meet the needs of traditional and e-science application developers. It allows the deployment of a variety of platforms, providing an access control model whereby developers may declaratively state how they wish their data and application resources to be automatically shared with other users. It relies on the concept of `separation of concerns', such that developers need only be concerned with creating their applications, entrusting MagosCloud Secure with the responsibility of providing a secure, highly scalable platform. Finally, the results of tests concerning the automatic generation of secure platforms, as well as run time considerations, are analyzed.","PeriodicalId":428764,"journal":{"name":"2012 International Conference on High Performance Computing & Simulation (HPCS)","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126264130","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}

Numerous benchmarks are used in industry to characterize the performance of standalone systems on the one hand, to measure the computational efficiency of massively parallel systems such as clusters, grids and supercomputers, on the other hand. One of the common features of performance evaluation of small or large standalone systems is that performance engineers have direct and full control over these systems. The peer-to-peer (P2P) paradigm, which involves volunteer participation for execution of lengthy and complex scientific computations, operates in an uncontrolled environment. The performance evaluation of participating nodes operating in an uncontrolled P2P environment is a challenging task. Currently, two traditional synthetic benchmarks (Dhrystone and Whetstone) are used as part of Berkeley Open Infrastructure for Network Computing (BOINC)'s Accounting System for granting credits to the participating nodes. The analysis of the performance data obtained from running Dhrystone and Whetstone on general purpose computers has highlighted the limitations of these benchmarks. This study proposes a new synthetic light-weight benchmark - MalikStone, which is representative of large P2P projects and has been specifically designed in view the dynamic nature and challenges of the P2P paradigm. The benchmark integrates the strengths of existing synthetic benchmarks and provides more detailed insight into system performance by capturing the context in which the benchmarking was performed. The results of this newly designed benchmark have been found to be encouraging. Compared with existing synthetic benchmarks, Dhrystone and Whetstone, and the SPEC CPU2006 benchmarking suite, we highlight MalikStone's superiority in characterizing system performance in P2P settings.","PeriodicalId":428764,"journal":{"name":"2012 International Conference on High Performance Computing & Simulation (HPCS)","volume":"os-42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127783462","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}
