P4 is one of the layers that MPICH (a popular and very well done
implementation of MPI) supports. MPI itself is a standard definition
and not a library. the architecture of your MPI library depends on
what the implementors have done to implement the standard. the layers
that might be hidden depend on what your MPI implementations supports.
