Grid systems have huge and changeable user groups, and different autonomous domains always have different security policies. The attribute based access control (ABAC) model, which is flexible and scalable, is more suitable for Grid systems. This paper describes a method of building a flexible access control mechanism that is based on ABAC and supports multiple policies for Grid computing. Firstly ...... hiện toàn bộ

Setting up and deploying complex applications on a Grid infrastructure is still challenging and the programming models are rapidly evolving. Efficiently exploiting Grid parallelism is often not straight forward. In this paper, we report on the techniques used for deploying applications on the EGEE production Grid through four experiments coming from completely different scientific areas: nuclear f...... hiện toàn bộ
Adaptive Executions of Multi-Physics Coupled Applications on Batch GridsSpringer Science and Business Media LLC - Tập 9 - Trang 455-478 - 2011

Long running multi-physics coupled parallel applications have gained prominence in recent years. The high computational requirements and long durations of simulations of these applications necessitate the use of multiple systems of a Grid for execution. In this paper, we have built an adaptive middleware framework for execution of long running multi-physics coupled applications across multiple bat...... hiện toàn bộ
Efficient Workflow Scheduling for Grid Computing Using a Leveled Multi-objective Genetic AlgorithmSpringer Science and Business Media LLC - Tập 12 - Trang 637-663 - 2014
Hassan Khajemohammadi, Ali Fanian, T. Aaron Gulliver
Task scheduling and resource allocation are important problems in grid computing. The workflow management system receives inter-dependent tasks from the users and allocates each task to an appropriate resource based on user requirements and constraints such as budget and deadline. Thus this system has a significant effect on performance and the efficient use of resources. In general, mapping tasks...... hiện toàn bộ

Enterprises increasingly recognize the compelling economic and operational benefits from virtualizing and pooling IT resources in the cloud. Nevertheless, the significant and valuable transformation of organizations that adopt cloud computing is accompanied by a number of security threats that should be considered. In this paper, we outline significant security challenges presented when migrating ...... hiện toàn bộ
Digital Preservation in Grids and Clouds: A Middleware ApproachSpringer Science and Business Media LLC - Tập 10 - Trang 133-149 - 2012
Peter Wittek, Sándor Darányi
Digital preservation is the persistent archiving of digital assets for future access and reuse, irrespective of the underlying platform and software solutions. Existing preservation systems have a strong focus on Grids, but the advent of cloud technologies offers an attractive option. We describe a middleware system that enables a flexible choice between a Grid and a cloud for ad-hoc computations ...... hiện toàn bộ
