 \title{A scalable multisplitting algorithm for solving large sparse linear systems}

@@ -352,6 +356,30 @@ obtained for  a 3D Poisson  problem, the number  of iterations is high.  Using a
 preconditioner  it  is   possible  to  reduce  the  number   of  iterations  but
 preconditioners are not scalable when using many cores.
 
+Doing many experiments  with many cores is  not easy and require to  access to a
+supercomputer  with several  hours for  developping  a code  and then  improving
+it. In the following we presented  some experiments we could achieved out on the
+Hector architecture,  the previous UK's  high-end computing resource,  funded by
+the UK Research Councils, which has been stopped in the early 2014.
+
+In the experiments  we report the size of the 3D  poisson considered, the number
+of processors used  (with the decomposition for the  multisplitting), the number
+of iterations for the GMRES method and the krylov multisplitting one and finally
+the execution  times. We  also give  the other parameters:  the restart  for the
+GRMES method
