In this section, the results for the different simulations will be presented,
-and we'll try to explain our observations.

\subsubsection{Cluster vs grid platforms}
\subsubsection{The \besteffort{} strategy with the load initially on only one
node}
-Before looking at the different variations, we'll first show that the plain
-\besteffort{} strategy is valuable, and may be as good as the \makhoul{}
-strategy. On the graphs from the figure~\ref{fig.results1}, these strategies
-are respectively labeled ``b'' and ``a''.

-twice faster on lines
-almost equivalent on torus
-worse on hcubes
+We can see that the relative performance of these strategies is mainly
+influenced by the application topology. It is for the line topology that the
+difference is the more important. In this case, the \besteffort{} strategy is
+nearly twice as fast as the \makhoul{} strategy. This can be explained by the
+fact that the \besteffort{} strategy tries to distribute the load faitly between
+all the nodes and with the line topology, it is easy to load balance the load
+fairly.
--> interconnection
+On the contrary, for the hypercube topology, the \besteffort{} strategy performs
+worse than the \makhoul{} strategy. In this case, the \makhoul{} strategy which
+tries to give more load to few neighbors reaches the equilibrum faster.
+
+For the torus topology, for which the number of links is between the line and
+the hypercube, the \makhoul{} strategy is slightly better but the difference is
+more nuanced.
+
+Globally the number of interconnection is very important. The more
+interconnection links there are, the faster the \makhoul{} strategy is because
+it distributes quickly significant amount of load even if this is unfair between
+all the neighbors. In opposition, the \besteffort{} strategy distributes the
+load fairly so this strategy is better for low connected strategy.
-plus c'est connecté, moins bon est BE car à vouloir trop bien équilibrer
-localement, le processeurs se perturbent mutuellement. Du coup, makhoul qui
-équilibre moins bien localement est moins perturbé par ces interférences.
\subsubsection{With the virtual load extension with the load initially on only
one node}
qu'il y a beaucoup de voisins.
\subsubsection{The $k$ parameter}
+\label{results-k}
Dans le cas où les comms coutent cher et ou BE se fait avoir, on peut ameliorer
les perfs avec le param k.
