In this paper, the authors present a tool to extract I/O traces from very large applications running at full scale during their production runs. They analyze these traces to gain information about the application. They analyze the traces of three applications. The analysis showed that the I/O traces reveal much information about the application even without access to the source code. In particular, these I/O traces provide multiple indications towards the algorithmic nature of the application by observing the changes of data amount and I/O request distribution at the checkpoints.
