Teuta: Tool Support for Performance Modeling of Distributed and Parallel Applications

摘要

In this paper we describe Teuta, which we have developed to provide tool support for the UML-based performance modeling of distributed and parallel applications. Teuta features include model checking and model traversing. Model checking is used to verify whether the model conforms to the UML specification. In addition, Teuta supports semantic model checking for the domain of high performance computing. For the generation of different model representations the model traversing is used. In addition, we present our methodology for automatic generation of the simulation model from the UML model of an application. This simulation model is used to evaluate the performance of the application. We demonstrate the usefulness of Teuta by modeling LAPWO, a distributed material science application.
