QoS Aware and Service-Oriented Workflow on GRID

초록

영어

As the main computing paradigm for resource-intensive scientific applications, Grid[1] enables resource sharing and dynamic allocation of computational resources. Large-scale grids are normally composed of huge numbers of components from different sites, which increases the requirements of workflows and quality of service (QoS) upon these workflows as many of these components have real-time requirements.
In this paper, we describe our web services based QoS-aware workflow management system(WfMS) from GridCC project[7] and show how this WfMS can aid to ensure workflows meet the pre-defined QoS requirements and optimise them accordingly.
