Parallel application signature

We seek to achieve characterization or application signature from a parallel application that will allow us, through the execution of this signature, to evaluate its performance in different computers. Sequential applications behavior can be understood by means of tools such as SimPoint. This tool can identify and select significant phases describing the applications behavior. Our proposal is to extend those concepts towards parallel applications, with the goal of modeling and predicting the parallel application. To achieve this, we developed a methodology, enabling us to identify and extract repetitive behavior to create the application signature. We have validated our proposal using scientific applications such as the NAS Parallel Benchmarks, Sweep3D. We could predict the execution time of the entire application.
