Accounting system is one of the building blocks in the grid computing and cloud computing environments. Despite its growing significance, the quality of accounting service suffers from several problems, including the tight coupling relationship between the accounting methods and the accounting log files, slow updates, and ignorance on the impact of user behavior. To address the above problem, an accounting...
The unilateral dynamic change of access policy between different domains in the grid computing platforms would incur global inconsistent privileges. To address the problem, this paper proposes a new component named coordinated negotiation policy and introduces it into authorization mechanism in the grid system. Based on the policy repository stating how to response to the change of privileges, the...
The dynamic change of users and resources would incur the overall inconsistency of the access policies between different domains in grid. This would have a bad effect on the grid operations, and compromise the grid system. To address the problem, this paper proposes an automated negotiation engine combining with the authorization mechanism. The engine can detect timely the change of access policies,...
To facilitate the co-allocation and co-scheduling of software and hardware resources in grid environment, a License-aware meta-scheduling engine was proposed. The License-aware schedule model was analyzed and three criteria including the license utilization, loss rate of average job completion time were defined for evaluate the performance of engine. We extend the heuristic scheduling algorithms from...
The monitoring service is a crucial component in the service oriented grid infrastructure. Objectives and requirements for the grid monitoring system have been summarized in this paper. To cope with the dynamic and large-scale nature of the grid, a scalable distributed monitoring system is proposed, which can support easy and rapid deployment of monitoring services in the grid environments. The BitTorrent...
Software licenses are valuable resources in the grid environment, and how to manage them efficiently has become an active topic of research for computational grid. This paper proposes an approach for organizing and managing software licenses in grid environment, based on which a grid-specific license manager of software sharing system is designed and implemented. The license manager is independent...
This paper describes a script-based approach to automate the deployment of grid monitoring service component. Automated deployment service uses the information of dynamically joined nodes to deploy system component, which avoids the potential errors and inconvenience by manual deployment. Our system archives the status information of resources in MySQL and RRD database to optimize the system performance...
In this paper we develop a Floating License related Software Sharing system for leveraging software and hardware resources in Grid environment. We do so by analyzing limitations of existing license management systems and describing how characteristics of floating license affect software sharing. We present be compatible with the software's original Graphical User Interface helps reduce the complexity...
