Information grid makes up for the lack of conventional information system in distributed information application, and provides a new mode of using the information resources for uses. As Agent is the branch of distributed artificial intelligence, the system which combined Agent with other distributed technologies also became important research topics currently. Based on detailed analysis to Agent technology...
The domains of usage of large-scale distributed systems have been extending during the past years from scientific to commercial applications. Together with the extension of the application domains, new requirements have emerged for large-scale distributed systems. Among these, fault tolerance is needed by more and more modern distributed applications, not only by the critical ones. In this paper we...
This paper describes a generic architecture for agents that allows agents to adapt to dynamic environments by using a trust mechanism in conjunction with machine learning. Central parts of the architecture are an Observer/Controller loop and a trust aggregation mechanism. It is shown how this proposed architecture can be applied to agents that act on behalf of a user in a decentralised desktop grid...
While the advances in networking technologies actually enable mobility and ubiquity of access to computing resources located at different administrative domains, the progress in multimedia technologies has created large amounts of digital content that can be purchased and distributed on the Internet. Within this setting, the problem of the copyright protection of digital content has become a well-known...
The SORMSYS project's main goal is to optimize resource management in large scale distributed systems with the capability of self-organization. This paper will present the design of management architecture based on existing middleware solutions through the design of algorithms and methods inspired by natural models. The architecture is full decentralized and it will aim to optimize resource management...
The following topics are dealt with : computer architecture; data intensive and I/O computing; algorithm and application; P2P computing; service-oriented architecture; cluster computing; grid computing; cloud computing; performance evaluation; compilers and language; information retrieval; knowledge discovery; OS/resource management; wireless networks; and pervasive computing.
With the development of spatial information technology, remote sensing data processing has become a kind of important service to the public. Traditional processing mode with one single machine and one software can't meet the demand of various requirements and high performance processing though there exist various isolated remote sensing resources such as data, software over network. Grid is a infrastructure...
Grid monitoring is a process to collect information regarding the current and past status of large-scale distributed grid computing resource. It is still a challenge to efficiently cope with the highly complicated issues of monitoring distributed heterogeneous resources of different ownerships in Grids. For that, we propose PFRA-GMA (PerformanceForecast and Resource-Autonomy Grid Monitoring Architecture)...
An UML approach to designing Resource Oriented Architecture (ROA) is described in this article along with a case study on Smart Grid Home Area Network (HAN). A set of UML diagrams is presented to illustrate steps from requirements collection, data flow, resource data modeling, to the interface model. The process provides an example on how to design ROA in a standardized way from a modeling perspective...
Technology is advancing rapidly and the demand and expectation is getting higher, that current monolithic client-server and peer-to-peer e-learning systems can no longer tolerate. Distributed e-learning systems, on the other hand, have the potential to address many shortcomings of current e-learning systems. Distributed systems are mainly based on Web-services or alternatively the Grid. The purpose...
The DynaSOAr framework presents a wholly service-oriented approach to grid and Internet-based computing that makes a clear and explicit separation of concerns between service-provision and resource-provision for each service invocation. The separation allows the dynamic deployment of code at runtime, in the form of a service implementation, between a service provider and an explicit resource provider...
The Service-Oriented Architecture (SOA) leverages the service abstraction to enable the development of modular, loose-coupled and distributed applications. In order to use such an architecture, service-based applications directly rely on services or compose them for conceiving new functionalities. In spite of these capabilities, they do not support the development of services which need high-performance...
Based on the comparison of advantage and disadvantage between Google and digital library, a method for service chain of digital library based on service-oriented architecture (SOA) is presented. Then an integrated framework for service chain of digital library is put forward, and the information exchange approach and software system architecture layers based on SOA are discussed. Finally, based on...
There exist many methods for evaluating the quality of product line architectures (PLAs). However, none of them have been applied considering the inherent particularities of PLAs for grid oriented middleware systems. This paper presents how an existing method, named FAE (Family Architecture Evaluation), has been adapted to be applied to evaluate a PLA for grid oriented middleware. In order to validate...
With the increasing prevalence of large scale cloud computing environment, researchers has draw more attention about how to provide software as a service through the internet. In this paper, a novel approach named vSaaS is proposed in iVIC platform, which is the virtual computing environment for HaaS and SaaS applications. The aim of this approach is to provide the software as a service from a cloud...
As an organic composition of Digital Earth, Digital Forestry is a dynamic concept and its technologies is developed and perfected accompanied with the development of information technology and management techniques. The information and data of the Digital Forestry is wide, rich content, huge and dispersed. It is an urgent problem how to integrate these data and make it useful for forestry decision-making...
Technological advances in wireless networks and mobile devices are driving towards a new concept of grid computing, in which mobile users play an active role. For this reason, classical wired grid infrastructures are being extended in order to provide facilities which enable mobile users to exploit services available in the environment. Since grid computing borrows such facilities from pervasive computing,...
Ultra large scale (ULS) systems are future software intensive systems that have billions of lines of code, composed of heterogeneous, changing, inconsistent and independent elements that are dispersed through worldwide global networks. Huge scale of this heterology in addition to distinctive characteristics like decentralization of operation, management, deployment and evolution, continuous evolving,...
FAFNER is code developed by Lister which simulates by Monte Carlo methods the Neutral Beam Injection (NBI) technology, one of the most extended heating methods for fusion devices. To the date, FAFNER has been usually run at CIEMAT adapted to the TJ-II helical axis stellarator on shared memory Cray architecture machines. From this version, FAFNER has been ported to the Grid in the framework of the...
