+\begin{abstract}
+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.

+\section{Introduction}
 
-This paper presents ....
-It's done...
+Iterative methods used  to solve large sparse linear systems  of the form $Ax=b$
+because they are easier to parallelize than direct ones.
