This report presents optimisations mechanisms within MPICH/Madeleine , the implementation of MPICH over Madeleine. These mechanisms aim to decrease the communication time of derived datatypes for which data is stored in noncontiguous memory areas. The report presents the mechanisms as well as some performance evaluation.
