In the recent years, strong efforts have been dedicated on the study of applications' execution phases. In this paper, we show an approach focused on the automatic detection of the phases on MPI applications' execution. This detection is based on Wavelet Analysis, which provides a meaningful and fast methodology. Information derived from phase detection is very useful to study the performance of the application. To illustrate this importance, we show a study of the scalability of several applications based on phase detection.
