In this project you will practice memory access optimization, performance-oriented programming, and OpenMP parallelizaton 
on the ICS Cluster .  

\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:
