However, to date they have not been properly analysed with respect to the critical dimension of robustness. Indeed, the robustness evaluations found in the literature only cover a subset of the types of failure situations and generally lack a comprehensive architectural classification. In this context, this paper introduces the necessary foundations for systematic evaluation of the robustness of pub/sub system: a comprehensive classification scheme and a complete taxonomy of failures. We argue that both robustness evaluation of pub/sub systems and development methods of robust pub/sub systems should take rational behavior into account. We demonstrate this point through an experimental study.","PeriodicalId":251730,"journal":{"name":"2011 International Conference on P2P, Parallel, Grid, Cloud and Internet Computing","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116109406","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}

Cluster computing has developed due to the availability of high performance cost effective processors and high speed networks. The long-term trend in High performance computing requires increasing number of nodes in parallel computing platforms. This however entails a higher failure probability. The Message Passing Paradigm (MPI) is currently the programming paradigm and communication library most commonly used on parallel computing platforms. MPI applications may get stopped at any time due to unpredictable failures during execution. In our paper we propose an efficient fault tolerant approach for MPI system in an asymmetric cluster computing environment. In this paper, we use centralized logging process. In the approach proposed, we use message logging for message losses. The process has three main parts failure detection, failure recovery and overload detection. Our System maintains monitor nodes for all nodes in cluster, the difference being all monitor nodes can work as a cluster node even when the system is functioning properly and not just at the time of node failure.","PeriodicalId":251730,"journal":{"name":"2011 International Conference on P2P, Parallel, Grid, Cloud and Internet Computing","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117088544","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 main problems in data grid are job scheduling and data management. Generally, job scheduling in Grid has been studied from the perspective of computational Grid. In Data Grid, effective scheduling policy should consider both computational and data storage resources. In this paper a new job scheduling algorithm, called Combine Scheduling Strategy (CSS) is proposed that considers number of jobs waiting in the queue, location of required data and the computing capacity of sites. Scheduling cannot be effective unless to combine it with replication. Therefore, we have discussed various strategies in scheduling and replica optimization. Simulation results demonstrate that CSS gives better performance compared to the other algorithms.","PeriodicalId":251730,"journal":{"name":"2011 International Conference on P2P, Parallel, Grid, Cloud and Internet Computing","volume":"96 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123188315","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}

We focus on the performance bottleneck of one of the most pressing applications and their average response time. Therefore we present the software architecture of this web-application, called \"Study-Portal\" of the University of Mannheim, and we identify typical workload scenarios. We discuss our performance measurements and document the software and hardware infrastructure used during the measurements. Our goal is the identification of the most influential parameters which determine the timing behavior of the combined web-application. For the modeling we will use standard stochastic methods, even if it will mean over simplification. Our results then provide a simple estimate for the considered web-application: a doubling of application servers leads to half of the response time in case of sufficiently many clients. The developed model fits well with the observations in the operating environment of an IT-center.","PeriodicalId":251730,"journal":{"name":"2011 International Conference on P2P, Parallel, Grid, Cloud and Internet Computing","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129564759","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}

Initially, the objective of such techniques was to ensure availability of immutable information (typically files) in P2P systems under highly dynamic nature of large P2P systems. But also dynamic documents, which are documents that change over time, can be replicated. In this case, consistency issues must be addressed. It is therefore interesting to study different replication techniques for dynamic files in the context of a peer-group. In this paper, we propose a replication system for documents structured as XML files and evaluate them under different scenarios. The proposed system has a super-peer architecture that provides fast consistency for late joining peers. It uses optimistic replication techniques with propagating update operations from source node to destination node in push mode. The system is suitable for asynchronous collaboration, which arises in online collaborative teams accomplishing a common project in a P2P environment.","PeriodicalId":251730,"journal":{"name":"2011 International Conference on P2P, Parallel, Grid, Cloud and Internet Computing","volume":"117 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134580823","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, grainy video is displayed on largescale screen to depend on the display resolution specification of display equipments such as a projector and wide-area monitor, and sufficient quality is not obtained. In this paper, we have constructed remote communication environment with tiled display wall in multipoint sites and have conducted experiment in order to study the possibility of realistic remote communication with multi-video streaming. From experimental results, these video streaming from each site have been shown to display more high-quality than expanded video image by single small camera.
