Recently, MPI+OpenMP hybrid paradigm codes have been proved high performance efficiency in many applications and have been widely studied. But its relationship with MPI and OpenMP paradigm codes still need further study. In this paper, we focus on two aspects, the overhead and the number of processors definition methodology, to discuss the relationship between MPI, OpenMP and MPI+OpenMP paradigm codes. This paper provides a collection of experimental results of these three paradigm codes. The experimental results demonstrate that the parallel efficiency of MPI+OpenMP hybrid paradigm code can be more properly figured out but its performance would not always be the best on SMPs, which means the application situation should be pre-studied.","PeriodicalId":163318,"journal":{"name":"Proceedings of 2013 3rd International Conference on Computer Science and Network Technology","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128968459","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}

To estimate the target state, we develop a distributed federated filter (DFF) approach where only local communication between sensors is required. This DFF algorithm has superiority in tolerance of the target system noise and can acquire accurate estimation even if the model of the target is not accurate. We value information-distribution and information-fusion weights in the DFF according to the measurement situations of sensors. Then a flocking-based motion control method is proposed to track maneuvering targets. During the process of tracking, velocity matching and collision avoidance among mobile sensors are guaranteed. Finally, this coupled estimation and control algorithm is successfully simulated to track a linear-dynamics target with non-zero acceleration. Simulation results verify the performance and superiority of our method.","PeriodicalId":163318,"journal":{"name":"Proceedings of 2013 3rd International Conference on Computer Science and Network Technology","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123939912","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, dataset of multi-field in HDFS is usually stored in just one-dimension. Analytics in Hadoop usually need to process the whole dataset in a brute way. In this paper, we introduce HView, an extension of data layout in HDFS, to store data according to multiple fields. HView provides people with different dimension views of the same dataset in HDFS. HView does not need to modify Hadoop, increase DataNode storage occupy or bring Namenode pressure. We exploit a use case of Map-side join for HView. Experiment result shows that HView can improve the efficiency of Map-side join and solve the problem of size limit in Map-side join.","PeriodicalId":163318,"journal":{"name":"Proceedings of 2013 3rd International Conference on Computer Science and Network Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121769152","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}

Combined with the other papers, this paper mainly uses the partial relaying selection and incremental relaying. In this paper, we analyze the end-to-end performance of incremental relaying cooperative diversity networks which uses amplify-and-forward relay stations (RS) over independent non-identical Rayleigh fading channels.

The working principle of a wavemaker system is generating desired waves by controlling the mechanical motion of wave paddle. The absorbing control system is realized by an infinite impulse response (IIR) digital filter that approximates the transfer function in frequency domain. This paper presents the design and implementation of the IIR filer for a piston-type absorbing wavemaker system in a 2D wave flume. Based on first-order wavemaker theory, a frequency domain absorption transfer function is modeled. Then an IIR filter is obtained by approximating the transfer function with non-linear least square optimization. In practical systems, time delay exists in the control loop. Therefore, a delay compensation term to the transfer function is proposed. Experimental results on a real system show that the system performs well for both regular and irregular waves.","PeriodicalId":163318,"journal":{"name":"Proceedings of 2013 3rd International Conference on Computer Science and Network Technology","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130279416","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}
