The proposed framework consists of four modules aiming at feature extraction, dimension reduction, bag of feature modeling, and supervised learning respectively. This distributed computing framework is implemented on Hadoop with Mahout support. We apply the framework for classifying whether a person is on calling or not in a surveillance video to verify the correctness and scalability.","PeriodicalId":255477,"journal":{"name":"Proceedings of 2014 International Conference on Cloud Computing and Internet of Things","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131846041","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}

The implementation uses a hash table to store particles data and divides the program code into 2 parts for parallelization. The first part has no data race, but the second part has data race. Then, the paper compares the running time and parallel speedup of each part to find the bottleneck of the parallel SPH program. The results show that the program can achieve linear speedup just with the first part to be parallelized when the search radius is large. And the second part has become a performance bottleneck only when the search radius is small enough (for each cell only contains one or two particles on average). We present a method to parallelize the second part without affecting the performance of the first part. The results show that our method can ease the performance bottleneck when the search radius is small.","PeriodicalId":255477,"journal":{"name":"Proceedings of 2014 International Conference on Cloud Computing and Internet of Things","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126799766","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}

Using virtualization technology, a single physical machine can provide multiple isolated virtual machine to users, which will improve the overall system resources usage. However, virtualization will also introduce new challenges and mechanisms that work functionally in traditional operating system may lead to the performance degradation of virtual machines. LHP problem arises because spin lock mechanism could not work effectively in virtualization environment. To solve LHP problem, many solutions have been proposed to reduce its performance impact on virtual machines and improve the overall system performance. A hardware assisted technology called Pause Loop Exit(PLE) has been proposed to help detecting spin lock waiter in virtual machines and then reduce the cpu time used in spinning. In this paper, we verify the necessity of adjusting PLE configuration in different scenarios. Our experiment results show that it is necessary to adjust PLE configuration when the virtual machine is running different applications and the number of virtual machines varies.","PeriodicalId":255477,"journal":{"name":"Proceedings of 2014 International Conference on Cloud Computing and Internet of Things","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121949810","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}

When building the routing table, this protocol stores the current channel states and restricts the VANET nodes, excepted source/ destination nodes, from obtaining the unrelated routing information. During the information transmission process, the presorted channel states in network layer are transparently transmitted to the physical layer, and decomposed as total channel state. The decomposed results, which are only known by the source/destination nodes from routing information, can be utilized to equalize the channel and to demodulate the information. As a result, the other nodes cannot effectively equalize the channel, which causes little information can be eavesdropped. The theory analysis and simulation illustrate that, when the destination nodes obtain the good signal quality, the eavesdropper suffers poor bit error rate.","PeriodicalId":255477,"journal":{"name":"Proceedings of 2014 International Conference on Cloud Computing and Internet of Things","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122281724","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}
