+\section{Explaining Memory Hierarchies \punkte{25}}
+
+By identifying the memory hierarchy parameters through \texttt{likwid-topology} 
+for the cache topology and \texttt{free -g} for the amount of primary memory I
+find the following values:
+
+\begin{center}
+\begin{tabular}{llll}
+Main memory & 62 GB              \\
+L3 cache    & 25 MB per socket   \\
+L2 cache    & 256 kB per core    \\
+L1 cache    & 32 kB per core    
+\end{tabular}
+\end{center}
+
+All values are reported using base 2 IEC byte units. The cluster has 2 sockets
+and a total of 20 cores (10 per socket). The cache topology diagram reported by
+\texttt{likwid-topology -g} is the following:
