increase of more than $75\%$ (resp. $82\%$) of the execution for the classical
GMRES (resp. Krylov multisplitting) algorithm. The execution time factor
between the two algorithms varies from 2.2 to 1.5 times with a network latency
-decreasing from $8.10^{-6}$ to $6.10^{-5}$.
+decreasing from $8.10^{-6}$ to $6.10^{-5}$ second.

grid 4 $\times$ 8 leading to the same conclusion.
