They are included into grids or become key components of large structures. As more users and projects rely on RFC clusters, high availability and security are requirements for a fast growing adoption and use. In this paper, we, focus on high performance networks. All HPC clusters are built on top of them. We demonstrate that classical instrumentations are inefficient in HPC environment, they do not scale or cause a significant loss of performance. Based on this fact, we highlight clusters properties; nodes have assigned roles and are coupled at various levels. Moreover, we study the main characteristics of resource usage for each type of node and propose an instrumentation that can be effectively deployed. It results in fine-grained mechanisms adapted to system architecture, and performance constraints. Relevant information is collected over time. Two properties are verified online and dynamically: coherency and containment. Each induces a type of verification and both aim at reducing recovery time from failure and security risk of a whole cluster. We illustrate our methodology on QsNet by K. Magontis et al.

It provides diverse information to users or other service components in Grid environments. In this paper, we propose an Information Service architecture model for information management in a Grid Virtual Organization (VO). This Information Service is a hierarchical structure which consists of the VO layer, site layer and resource layer: at the resource layer, information agents and pluggable information sensors are deployed on each resource monitored. This information agent and sensor approach provides a flexible framework that enables specific information to be captured; at the site layer, a site information service component with caching capability aggregates and maintains up-to-date information of all the resources monitored within an administrative domain; at the VO layer, a peer-to-peer approach is used to build a virtual network of site information services for information discovery and query in a large scale Grid VO. This decentralized approach makes information management scalable and robust. Our Information Service has been implemented based on the Globus Toolkit 4 as a Web service compliant to the Web Services Resource Framework (WSRF) specifications. The experimental results show that the Information Service presents satisfactory scalability in handling information for large scale Grids.","PeriodicalId":419226,"journal":{"name":"Sixth IEEE International Symposium on Cluster Computing and the Grid (CCGRID'06)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116274981","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}

Lanza","doi":"10.1109/CCGRID.2006.130","DOIUrl":"https://doi.org/10.1109/CCGRID.2006.130","url":null,"abstract":"Providing health care outside major hospitals is difficult enough in urban settings, but is even more problematic in isolated places such as small towns. Sicily is an especially challenging case because it is a large island off the main track of mainstream Europe and contains many rural villages as well as numerous smaller islands. Although the major cities in Sicily currently have some well-equipped hospitals with expert staff, rare or complex diseases (e.g. neuropathology) still require support from national or international sources. There is no infrastructure for communication with such distant health-care centers, necessitating the transport of patients over long distances. The goal of the present project is to establish such a communication network to enable medical staff in remote locations, even at a patient's home, to access databases (e.g. pharmacological), consult with clinicians on diagnosis, and even transmit monitored patient vital signs in real time. It is possible to create such a network gradually so that each step would be in operation even before the entire project is completed. This paper describes the knowledge-base, human resources and technical requirements for each step","PeriodicalId":419226,"journal":{"name":"Sixth IEEE International Symposium on Cluster Computing and the Grid (CCGRID'06)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121684271","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}

Prospects for a biodiversity grid: managing biodiversity knowledge 生物多样性网格的前景:管理生物多样性知识

{"title":"Prospects for a biodiversity grid: managing biodiversity knowledge","authors":"Andrew C. Jones","doi":"10.1109/CCGRID.2006.160","DOIUrl":"https://doi.org/10.1109/CCGRID.2006.160","url":null,"abstract":"A wide variety of data has been collected by individuals and groups, for use in biodiversity-related scientific research. There is a need to be able to select and combine relevant biodiversity data, perhaps in ways the original creators did not envisage, and to use it in conjunction with other data such as climate data in order to perform analyses to answer important biodiversity questions. In this paper the author outlines the need for biodiversity e-Science problem solving environments underpinned by suitable grids, discussing what one might expect to characterise such a system, and identifying the kinds of problems that need to be solved in order to create a usable environment for biodiversity researchers. Techniques for data access and interoperability are discussed, drawing on experience in the BiodiversityWorld, BioDA and BUFFIE projects. These include the provision of an interoperation platform and the use of ontologies as a basis for determining data transformations. The author then concentrates on a very specific problem in biodiversity e-Science that needs to be addressed. This problem is the variation of opinion among experts which leads to conflicting ways of classifying, naming and describing organisms, and differing opinions about the reliability of other scientists' work. An early prototype created in order to explore these issues, myViews, is described. In this prototype it is possible, among other things, to transform data that reflects a given perspective into another that reflects the user's perspective. The author concludes by discussing the wider relevance of this work and, in particular, its relevance to the provision of metadata relating to biodiversity globally unique identifiers","PeriodicalId":419226,"journal":{"name":"Sixth IEEE International Symposium on Cluster Computing and the Grid (CCGRID'06)","volume":"52 9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131256692","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}
