In this service-oriented network virtualization environment, two important but somehow contradictory technical challenges are 1) how to select an optimal service path in order to meet the QoS requirements by users, and 2) how to balance the loads to fully utilize the whole systems. In this paper, we present an adaptive service path selection algorithm in service-oriented network virtualization environment, which assures QoS and balances the load at the same time. The proposed algorithm selects appropriate component services from multiple candidate service instances running on virtual machines and creates an optimal service path satisfying the users' QoS requirements. Our algorithm also dynamically adapts to the optimal service path based on various changes. Since the proposed algorithm handles a variation of the multi-constrained path selection problem known as NP-complete, we formulate the problem using ant colony optimization algorithm. The experimental results show that our algorithm guarantees the maximal QoS to the users while balancing the load at the same time, and adapts to the optimal service path based on the situational changes.","PeriodicalId":160979,"journal":{"name":"2013 International Conference on Parallel and Distributed Systems","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125801787","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}

Moreano","doi":"10.1109/ICPADS.2013.21","DOIUrl":"https://doi.org/10.1109/ICPADS.2013.21","url":null,"abstract":"Comparing a biological sequence to a family of sequences is an important task in Bioinformatics, commonly performed using tools such as HMMer. The Viterbi algorithm is applied as HMMer main step to compute the similarity between the sequence and the family. Due to the exponential growth of biological sequence databases, implementations of the Viterbi algorithm on several high performance platforms have been proposed. Nevertheless, few implementations of the Viterbi algorithm use GPUs as main platform. In this paper, we present the development and optimization of an accelerator for the Viterbi algorithm applied to biological sequence analysis on GPUs. Some of the optimizations analyzed are applied to the sequence comparison problem for the first time in the literature and others are evaluated in more depth than in related works. Our main contributions are: (a) an accelerator that achieves speedups up to 102.90 and 60.46, with respect to HMMer2 and HMMer3 execution on a general purpose computer, respectively, (b) the use of the multi-platform OpenCL programming model for the accelerator, (c) a detailed evaluation of several optimizations such as memory, control flow, execution space, instruction scheduling, and loop optimizations, and (d) a methodology of optimizations and evaluation that can also be applied to other sequence comparison algorithms, such as the HMMer3 MSV.","PeriodicalId":160979,"journal":{"name":"2013 International Conference on Parallel and Distributed Systems","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125399354","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}

However, the non-predetermined mapping of the Map-Reduce tasks to the physical machines makes it difficult to utilize the pre-partitioned and indexing techniques of DBMS to improve the data locality. In this paper, towards multi-way join evaluating OLAP (Online Analysis Processing) workloads, we introduce table partitioning by reference to Map-Reduce. For avoiding the dispersion of the initial tuples that belong to the same segment keys, we present a detailed description of the data organization model that partitions the dominated tables by cascade reference constraints. In order to push multiple joins on these clustered partitions down to the map task, we design a one-pass multi-way join algorithm along with its optimization implementations for the major Map-Reduce stages. We conduct an empirically study with TPCH benchmark on different scales of clusters, and experimentally verify the high efficiency of the proposed optimization model.","PeriodicalId":160979,"journal":{"name":"2013 International Conference on Parallel and Distributed Systems","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124559976","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}

Numbers of vehicles are significant increase every year and many cases of vehicle theft and missing thus internet of things (IoT) is a technology can be use to overcome the issues. This paper presents on the use of RFID vehicle plate number (e-plate) for tracking and management system. Started by design RFID e-plate antenna based and vehicle plate number size to achieve optimum performance by utilization of plate number size then an RFID chip attached to the plate. Proposed antenna of e-plate design using a low cost FR4 material and antenna band works at 902-928 MHz frequency for UHF RFID application, with result 3.8 dbi antenna gains there is performance improvement compared to the current tag antenna. The shape of antenna is rectangular and has a dimension of 300 mm x 100 mm, which is usually the typical size of the conventional vehicle registration plate number. Since vehicle e-plate used RFID chip and some information stored inside the tag then when RFID readers install at strategic point able capture vehicle information. All information collected by readers can be analyzed for vehicle tracking, monitoring and transportation management system.","PeriodicalId":160979,"journal":{"name":"2013 International Conference on Parallel and Distributed Systems","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124940694","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}
