-  The behavior of multicore applications is always a challenge to predict, especially with a new architecture for which no experiment has been performed. With some applications, it is difficult, if not impossible, to build accurate performance models. That is why another solution is to use a simulation tools that allows us to change many parameters of the architecture (network bandwidth, latency, number of processors) and to simulate the execution of such applications.

We have decided to use SimGrid as it enables to benchmark MPI applications.

 
 

-  In this paper, we focus our attention on two parallel iterative algorithms: one with synchronoous iterations and another one with asynchronous iterations.
+In this paper, we focus our attention on two parallel iterative algorithms based
+on the  Multisplitting algorithm  and we  compare them  to the  GMRES algorithm.
+These algorithms  are used to  solve libear  systems. Two different  variantsof the Multisplitting are
+studied: one  using synchronoous  iterations and  another one  with asynchronous
+iterations. For each algorithm we have  tested different parameters to see their
+influence.  We strongly  recommend people  interested  by investing  into a  new
+expensive  hardware  architecture  to   benchmark  their  applications  using  a
+simulation tool before.
