+RT Tests:
+\begin{itemize}
+\item cyclictest
+\item hwlatdetect
+\item pi\_stress
+\item signaltest

+\begin{frame}
+\frametitle{Cyclictest}
+\begin{itemize}
+\item Originally developed by Thomas Gleixner for Preempt RT testing
+\item High Resolution Timer test software
+\item Creates any number of cyclic realtime tasks with varying priorities and varying intervals
+\item Provides lots of debugging possibilities
+\item Yields very significant results to determine the realtime behavior of a platform
+\end{itemize}
+\end{frame}
+
+\begin{frame}
+\frametitle{Load Scenarios}
+Suitable load scenarios in order to create worst-case situations:
+\begin{itemize}
+\item CPU Load: ''hackbench'', orginally written for scheduler benchmarking
+\item Interrupt Load: flood pinging (''ping -f'')
+\end{itemize}
+\end{frame}
