\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:
