Tools like Globus Toolkit and MPICH-G2 have been developed to help scientists to facilitate their researches. As a Grid-enabled implementation of MPI, MPICH-G2 helps developers to port parallel applications to cross-domain environment. Since the current computationally-intensive parallel applications, especially long-running tasks, require high availability as well as high performance computing platform, dynamic job migration in Grid environment has became an essential issue. In this study, we present a dynamic job migration enabled MPICH-G2 version, MPICH-G-DM. We use Virtual Job Model (VJM) to reserve resources for the migrating jobs in advance to improve the efficiency of the system. An Asynchronous Migration Protocol (AMP) is proposed to enable the migrating sub jobs to checkpoint/restart and update their new addresses concurrently without a global synchronization. In order to reduce the communicating overhead of job migration, MPICH-G-DM minimized the number of control messages among domains to O(N). Experiment results show that MPICH-G-DM is effective and reliable.","PeriodicalId":212445,"journal":{"name":"2009 Fourth ChinaGrid Annual Conference","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133301250","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}

In addition, only data deadline and bandwidth are considered in the data scheduling algorithms in the existed protocols,which leads to the slow dissemination of newly generated content data.This paper first presents a strategic segment revelation policy that the source under-report the available data to its neighbors, while other peers announce all available data.According to simulation results, this policy can accelerate the dissemination of new segments, especially in low bandwidth environment. Then we propose a simple model of data scheduling which reveals the relation of download rate and other key factors in data scheduling. Based on this model, we further propose a greedy data scheduling algorithm, each data segment is given a priority according to its deadline and distribution among neighbors, and the segments with higher priority would be earlier requested such that these segments can be downloaded in the shortest time. The simulation results also indicate that the greedy data scheduling algorithm performs near-optimally in terms of bandwidth utilization.","PeriodicalId":212445,"journal":{"name":"2009 Fourth ChinaGrid Annual Conference","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127190490","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}

This paper takes the advantages of C4.5, ensemble learning and the MapReduce computing model, and proposes a new method MReC4.5 for parallel and distributed ensemble classification. Our experimental results show that increasing the number of nodes would benefit the effectiveness of classification modeling, and serialization operations at the model level make the MReC4.5 classifier “construct once, use anywhere”.","PeriodicalId":212445,"journal":{"name":"2009 Fourth ChinaGrid Annual Conference","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132843409","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}

In order to ensure the availability of grid monitoring, the reliability imposed by software or hardware failure happened with unpredictable probability must be assessed. This paper contributes to study the reliability analysis approach of grid monitoring in the context of grid monitoring architecture (GMA) that has been de facto standards for many areas of grid computing. Failure types and contributing factors in GMA are analyzed, which are likely to take place in comprised components, channels or process behaviors. Then, the respective evaluation equations are suggested via Markov procedure, queue model, and probability theory. Furthermore, the reliability issue of hierarchical GMA is discussed based on four basic architectural relations. Numerical examples are given to illustrate the proposed computing equations. The results show that our approach is feasible.","PeriodicalId":212445,"journal":{"name":"2009 Fourth ChinaGrid Annual Conference","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131881835","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}

Existing systems and proposals largely utilize scheduling mechanisms that are periodical in nature. We refer these as time-driven scheduling. In this paper we argue that the time-driven scheduling algorithm is not efficient for P2P VoD due to its inadequate resource utilization and inability in quickly adapting to the potential dynamics in such systems. We propose an event-driven scheduling algorithm for P2P VoD systems, in which the scheduler is triggered by events such as peer churn or/and random seeks. We evaluate our design through extensive simulations, and the experimental results show that event-driven scheduling outperforms time-driven scheduling in terms of both user experience and system scalability.","PeriodicalId":212445,"journal":{"name":"2009 Fourth ChinaGrid Annual Conference","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127028949","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 size of VM-level checkpoint may be very large and even in the order of gigabytes. This disadvantage causes the VM checkpointing and restart time become very long. To reduce the size of VM checkpoint, this paper proposes a memory exclusion scheme using ballooning mechanism, which omits saving unnecessary free pages in the VM. We implement our prototype in Xen environment. Experimental measurements show our approach can significantly reduce the size of VM checkpoint with minimal runtime overhead, thereby greatly improve the checkpoint performance.","PeriodicalId":212445,"journal":{"name":"2009 Fourth ChinaGrid Annual Conference","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130511326","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}
