In the scope of this paper, our first objective is to analyze when the Krylov
Multisplitting method has better performances than the classical GMRES
architecture and scaling up the input matrix size}

-In this section, we compare the algorithms performance running on various grid configuration (2x16, 4x8, 4x16 and 8x8). First, the results in figure 3 show for all grid configuration the non-variation of the number of iterations of classical GMRES for a given input matrix size; it is not

comparing between different grid architectures, even with the same number of
