+\section{Nbody}
+The nbody program has been executed with varying block sizes while the execution 
+time $t$ is measured, as shown in the figure \ref{fig:nbody.test}.

+\end{figure}

+The normalized time $\hat t$ is computed with the median time $t_m$ using $ \hat 
+t = t / t_{m} - 1 $. It can be observed that the normalized times exceed the 
+maximum allowed interval in most cases, except with the largest block sizes.
+
+Once the experiment \texttt{exp.nbody.test} changes, the hash of the experiment 
+program will change, therefore the plot will be updated and, lastly, this 
+report.
