Performance Assessment Architecture for Grid

For the sake of simplicity in resource sharing, Grid services only expose a function access interface to users. However, some Grid users want to know more about the performance of services in planning phase. Problem emerges since the Grid simply has no means in obtaining how well the system will cope with user demands. Current Grid infrastructures do not integrate adequate performance assessment measures to meet the user’s requirement. In this paper, the architecture of Guided Subsystem Approach for Grid performance assessments is presented. We proposed an assessment infrastructure that allows the user to collect information to evaluate the performance of Grid applications. Based on this infrastructure, a user-centric performance assessment method is given. It is expected that this research will lead to some sort of extension in Grid middleware to facilitate the Grid platform the ability to handle applications with higher reliability requirements.
