ARCHER2: Advanced MPI - Session 1

The most recent MPI standard, MPI 5.0 approved on 5th June 2025, runs to over 1000 pages and includes a huge number of functions. Even the most basic of MPI operations, such as a matching pair of MPI_Send / MPI Recv calls, can be implemented in surprisingly complicated ways; a simple question such as “what happens if I post a send and there is no receive” may not have a simple answer! An understanding of how the MPI library is implemented in practice can therefore be useful for users wanting to achieve optimal performance.
