-\FIXME{explain how to read the graphs}
+As mentioned earlier, we simulated the different algorithms on two kinds of
+physical platforms: clusters and grids.  A first observation that we can make,
+is that the graphs we draw from the data have a similar aspect for the two kinds
+of platforms.  The only noticeable difference is that the algorithms need a bit
+more time to achieve the convergence on the grid platforms, than on clusters.
+Nevertheless their relative performances remain generally identical.

 
 

-\subsubsection{Main results}
+This suggests that the relative performances of the different strategies are not
+influenced by the characteristics of the physical platform.  The differences in
+the convergence times can be explained by the fact that on the grid platforms,
+distant sites are interconnected by links of smaller bandwith.
+
+Therefore, in the following, we'll only discuss the results for the grid
+platforms.  The different results are presented on the
+figures~\ref{fig.results1} and~\ref{fig.resultsN}.
