Emerging urgent computing tools can quickly allocate computational resources for the execution of time critical jobs. Grid applications and workflows often use Grid services and service-oriented architectures. Currently, urgent computing tools cannot allocate or manage Grid services. In this paper, we evaluate a service-oriented approach to Grid service access and provisioning for urgent comput...

The new generation of networks, distributed systems, grid computing, which allows users to share files and Users need to use different sources to provide. Grid computing system as one of the competing technologies for cloud computing can be considered to have many advantages for users. One goal of grid computing systems, the management of computing resources for processing user applications or ...

The security is essential for all the applications on network. For providing the security to many applications on the network, number of mechanism are used. Grid computing is believed to be ultimate solution for meeting the increasing computation needs of the organizations. At present major focus in Grid computing is to improve the performance of the grid. However, user running an application o...

Grid computing is a category of high performance computing environment facilitates to solve large scale computational demands. It involves various research issues such as resource management, task scheduling, security problems and information management. Task scheduling is an important element of parallel, distributed computing and grid computing. The main aim of task scheduling in grid computi...

Grid computing or computational grid has become a vast research field in academics. It is a promising platform that provides resource sharing through multi-institutional virtual organizations for dynamic problem solving. Such platforms are much more cost-effective than traditional high performance computing systems. Due to the provision of scalability of resources, these days grid computing has...

This paper analyzes security problems existing in Grid Computing System and describes the security mechanism in Grid Computing System. After briefly introducing the security abstract of grid computing system at Grid Security Basic Layer, several protocols are defined at Grid Security Protocol Layer based on security architecture model. Broker protocols are then thoroughly discussed.
