Managing the construction and use of Functional Performance Models in a Grid environment

This paper presents a tool, the performance model manager, which addresses the complexity of the construction and management of a set of functional performance models on a computing server in a grid environment. The operation of the tool and the features it implements to achieve this goal are described. Integration of functional performance models with a GridRPC middleware, using the tool´s interfaces is illustrated. Finally, an example application is used to demonstrate the construction of the models and experiments that show the benefit of using the detailed models are presented.
