This paper presents a method to hierarchically group compute nodes distributed across the Internet into logical clusters, and determine the relative location of the clusters. At inter-domain level, distance from landmarks (a small group of distributed reference nodes) is the basis for converting the location of nodes inside a complex network structure onto a simple geometric space. The position of compute nodes in this geometric space is the basis for partitioning nodes into clusters. For compute nodes within an administrative domain, minimum RTT is used as the metric to partition nodes into clusters. This approach leads to an efficient, scalable and portable method of clustering grid nodes and building a distance map among clusters. We demonstrate the system for automatic clustering by applying it to computation nodes distributed across five universities in Texas.","PeriodicalId":347929,"journal":{"name":"The 6th IEEE/ACM International Workshop on Grid Computing, 2005.","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124648637","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}

GROCK is a portal that facilitates mass screening of potential molecular interactions in the life sciences. The main purpose for developing GROCK has been to facilitate users the performance of huge amounts of computational tasks using the power of the grid. In GROCK we have considered issues of high availability, redundancy, failure recovery and maximal exploitation of available grid resources. After trying various approaches we have settled for LCG-submitter, a tool developed for the physics LHC project to solve some of our goals. In this paper we introduce GROCK and analyze its design goals, the challenges found and the solutions we came up with to overcome them.","PeriodicalId":347929,"journal":{"name":"The 6th IEEE/ACM International Workshop on Grid Computing, 2005.","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126703694","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 have implemented limited XML access control in Delegent, in order to supervise modifications of the XML-encoded XACML policies.

In this paper, we present a mechanism that enables end-users to transparently access the diverse services available in the HPC-Europa environment.

The framework is based on the RDF metadata infrastructure, allowing a rich and extensible description of resources and queries. To avoid flooding the network with a query, we propose a comprehensive semantics-based query forwarding strategy, which only forwards queries to semantically related nodes. After the related nodes have been located, the original RDF query is used to do the final query and retrieval. Results from simulation experiments demonstrate that this architecture is scalable and efficient.","PeriodicalId":347929,"journal":{"name":"The 6th IEEE/ACM International Workshop on Grid Computing, 2005.","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122079421","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 a services-oriented distributed computing environment like the grid, reputation systems can be utilized by clients to select between competing service providers. In this paper, we selected several existing reputation algorithms and adapted them to the problem of service selection in a grid-like environment. We performed a quantitative comparison of both the accuracy and overhead associated with these techniques under common scenarios. The results indicate that using a reputation system to guide service selection can significantly improve client satisfaction with minimal overhead. In addition, we show that the most appropriate algorithm depends on the kinds of anticipated attacks. A new algorithm we've proposed appears to be the approach of choice if clients can misreport service ratings.","PeriodicalId":347929,"journal":{"name":"The 6th IEEE/ACM International Workshop on Grid Computing, 2005.","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132283831","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}
