title: Running parallel simulation "erreur" mpirun
body: <p>I try to do a parallel simulation with 4 processors but it shows me this error, knowing that I do the same thing with a simple case and it works. But with my main case it doesn't work :/</p>

  NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.
  You may or may not see output from other processes, depending on
  exactly when Open MPI kills them.
