    55 '' ''' The call to MPI3 neighbourhood collectives has been added only to one routine in order to test the improvement before to extend the approach to all the routines that use 5-point stencil. The impact on performance due to the MPI3 halo exchange can be evaluated by measuring the time spent by the routine execution.''' ''
