The drastic increase in the commodity computer and network performance for the last generation has a resultant of faster hardware and more sophisticated software. But, the supercomputers of the current generation are still incapable of solving the current problems in the field of science, engineering, and business. This problems arises as a single machine cannot facilitate the availability of various...
A number of methods and mechanisms are used to safe data in distributed and cluster computing or homogenous kind of environment where we don't have much challenges for security. In contrast heterogeneous systems require proper attention has to be given on security of the data due to increasing need of computing, data sharing and interacting with other resources make the systems more vulnerable. Grid...
Federated Grid resources typically span multiple administrative domains and utilize heterogeneous schedulers. This complexity complicates not only provisioning of quality of service but also management and enforcement of end-user resource utilization allocations. to overcome these problems, we propose to combine high-level meta-scheduling techniques with lower-level fairs hare prioritization mechanisms...
Cloud Computing is catching more attention around the world with its excellent features in providing the services and advantages in economy both for the end-users and Cloud providers. However, due to lack of enough resources, Cloud vendors currently can only provide general resources and services, like computing as a service but not suitable for research on specific domain. Grid Computing, on the...
The development of web has brought rich applications and services, giving users convenience, but also causing that the user's information is locked and isolated, the users' resource are disperse, and the operation granularity is not uniform, which ultimately harm the end-users. This paper presents PGOS,Personal Grid Operation System, a general-purpose software for controlled sharing of cross-domain...
The main problem of cooperative operation in DLF is resource sharing and resource unified management under heterogeneous environment. Based on the theory of grid and its application, a content service grid for digital library federation (DLF) is constructed, and the components and their functions of every grid layer are analyzed. Then a method of resource sharing based on publish/subscribe notification...
Grid system has many great security challenges such as access control. The attribute-based access control model (ABAC) has much merits that are more flexible, fine-grained and dynamically suitable to grid environment. As an important factor in grid security, trust is increasingly applied to management of security, especially in access control. This paper puts forward a novel trust model in multi-domain...
Community Remote Sensing (CRS) is an emerging field where information is collected about the environment by the general public and then integrated into collections to provide a holistic view of the environment with local details. We argue the need for a common architecture for the cyber-infrastructure that will be necessary to cater to the needs of Community Remote Sensing systems. We identify the...
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...
Based on the virtual organization (VO) model with stakeholder-centric, this paper proposed a trust evaluation model with stakeholder-centric. The aim of the model is to establish the trust relationship between nodes in grid computing and to present the reliability of other nodes. It is more efficient to discover requested services using the model in this paper. In the trust evaluation model with stakeholder-centric...
In this paper, a Metascheduler architecture is proposed to be used on Cloud Computing environments. The aim of this Metascheduler architecture is to handle the submission of a service and to manage the infrastructure of the Grid resources belonging to the Cloud. Futhermore, this Metascheduler also aims of building the best pool of available resources for the implementation of the requests issued by...
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,...
In this paper we introduce a new software architecture for autonomic grid computing networks by military C4ISR (command, control, communications, computers and intelligence, surveillance, & reconnaissance) architecture. We discuss self-* property of autonomic grid computing networks in autonomic grid computing networks can lead and manage by C4ISR architecture because we found many held in common...
The current challenge for the financial services industry is to improve and refine the structures of the past to meet changing information requirements and to integrate them into existing enterprise architectures. In order to meet these computational demands, Grid computing presents a secure, reliable and scalable technology to provide shared access to heterogeneous resources.This paper presents a...
Grid is concerned with the sharing and coordinated use of diverse resources in distributed "virtual organizations.?? The dynamic and multi-institutional nature of these environments introduces challenging security issues that demand new technical approaches. In particular, one must deal with diverse local mechanisms, support dynamic creation of services, and enable dynamic creation of trust domains...
Along with the up-rising of knowledge economy, effective organizing multiple, distributed, heterogeneous knowledge resource and providing high-quality knowledge services for users have been becoming increasingly important. This paper proposes a novel concept of intelligent topic map for knowledge organization and knowledge services, which embodies the multi-level, multi-granularity and inherent relevant...
In grid environments, the deployment and management of application software presents a major practical challenge for end users. Performing these tasks manually is error-prone and not scalable to large grids. In this work, we propose an automation tool, ADEM, for grid application software deployment and management, and demonstrate and evaluate the tool on the Open Science Grid. ADEM uses Globus for...
The grid is emerging as a wide-scale distributed computing infrastructure that promises to support resource sharing and coordinated problem solving in dynamic multi-institutional virtual organizations. To describe data, the Web service issues have been extended with a relevance of grids in education. To successfully summarize this in terms of a Web service implementation strategy for a hypothetical...
Scientific workflows have shown great benefit as a means of orchestrating complex distributed scientific computations over grids and speed the advance of scientific progress. To address some requirements of scientific experiment, such as result reproducibility, sharing and validation, provenance support has become an essential component of scientific workflow systems. With the increase of the amount...
So far, methods of fault diagnosis have been numerous. But as the complexity of modern equipment, the variability of fault, as well as trends in global manufacturing, it is difficult for any separate organization of independent to complete all the work of fault diagnosis. This article reviewed the equipment fault diagnostic technology in the course of development, in particular, remote fault diagnostic...
