+In this paper we revist the krylov multisplitting algorithm presented in [ref]
+which uses a scalar method to minimize the krylov iterations computed by a
+multisplitting algorithm. Our new algorithm is simply a parallel multisplitting
+algorithm with few blocks of large size and a parallel krylov minimization is
+used to improve the convergence. Some large scale experiments with a 3D Poisson
+problem are presented. They show the obtained improvements compared to a
+classical GMRES both in terms of number of iterations and execution times.
