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. + +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.
