[This is preliminary documentation and is subject to change.]

Direct, low-level interface to the system MPI library. This low-level interface provides direct access to the unmanaged MPI library provided by the system. It is by nature unsafe, and should only be used by programmers experienced both in the use of MPI from lower-level languages (e.g., C, Fortran) and with an understanding of the interaction between managed and unmanaged code, especially those issues that pertain to memory pinning/unpinning.
