    201201In the recursive application of MSA awareness (`PSP_MSA_AWARE_COLLOPS=2`), a distinction is first made between inter- and intra-**module** communication and then, in a second step, likewise between inter- and intra-**node** communication within the modules if `PSP_SMP_AWARENESS=1` is set in addition. (Please note that a meaningful usage of `PSP_MSA_AWARE_COLLOPS=2` requires `psmpi-5.4.5` or higher.)

     203A larger benchmarking campaign concerning the benefits of the MSA-aware collectives on the DEEP-EST prototype is still to be conducted.
     204However, by using the [https://deeptrac.zam.kfa-juelich.de:8443/trac/wiki/Public/ParaStationMPI#ReportingofStatisticalInformation histogram] feature of !ParaStation MPI, it could at least be proven that the number of messages crossing a Gateway can actually be reduced.
