Achieving high performance on CPUs or GPUs requires careful consideration of their different architectures, which challenges the capability and skills of programmers. In order to overcome the portability problem, OpenCL, a free cross-platform programming standard, is proposed by Khronos Compute Working Group. However, the performance of OpenCL-based programs has not been thoroughly studied yet. Therefore, in this paper, we first design OpenFFT-Bench, an FFT application with OpenCL-based FFT and OpenGL-based real-time spectrum visualization as the benchmark. We evaluate its performance on four OpenCL programming platforms including NVIDIA CUDA, ATI Stream (GPU), ATI Stream (CPU), and Intel OpenCL. Characteristics of OpenFFT-Bench are investigated with multiple FFT sizes. Experimental results show that OpenCL and OpenGL-based applications can not only run on multiple heterogeneous platforms, but also achieve relatively high performance on GPU-based platforms.","PeriodicalId":227472,"journal":{"name":"2011 International Conference on Cyber-Enabled Distributed Computing and Knowledge Discovery","volume":"155 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124337884","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}

Nodes communicate outside the cluster through a centralized node that is called a Cluster Head Gateway (CHG) [1]. MANET is a dynamic multi-hop network, which is established by a group of mobile nodes on a shared wireless channel. The shared medium and the multi-hop nature of the wireless ad hoc networks pose fundamental challenges to the design of an effective resource allocation algorithm to maximize the aggregated utility of flows, maintaining basic fairness among the multiple flows. An elected Cluster Head Gateway (CHG) is assigned for communication with all other clusters. The centralized Cluster Head Gateway can become a bottleneck and possibly cause a lower efficiency for the clustering system. In this paper we propose a mechanism in which communication outside the cluster is distributed through separate Cluster Head Gateways. We will discuss how the overall averaged efficiency for the clustering system increases considerably. We also show that the increase in overall averaged efficiency is by the increase/add Cluster Head Gateways. Additionally, the routing reliability to outside the cluster is increased since routes to different clusters use distinct Cluster Head Gateways.","PeriodicalId":227472,"journal":{"name":"2011 International Conference on Cyber-Enabled Distributed Computing and Knowledge Discovery","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128635606","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}

For example, churn, upselling and appetency are often considered together, and decisions on how to retain customers, and to promote or to upgrade services are associated. Instead of predicting them separately as univariate models, we propose an iterative procedure to model multiple responses prediction into correlated multivariate predicting scheme. This proposed method combines Partial Least Squares (PLS) method and logistic regressions, in which the former is used to extract the mutual information from correlations, while the latter is utilized to refine every single response prediction through auxiliary information from PLS. This hybrid regression modeling is implemented iteratively to refine the prediction gradually. More importantly, to exploit the positive exclusive property (i.e., positive for one response means negative for the others) between multivariate responses, before every round of iteration, all the positive predictions from the different responses compete each other and only the highest values are kept for positive predictions and the remaining is changed to negative. Numerical results show the proposed scheme can improve the conventional regression models significantly.","PeriodicalId":227472,"journal":{"name":"2011 International Conference on Cyber-Enabled Distributed Computing and Knowledge Discovery","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127254975","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}
