ARCHER2: Advanced MPI September 2023 Session 4

This course is aimed at programmers seeking to deepen their understanding of MPI and explore some of its more recent and advanced features. We cover topics including exploiting shared-memory access from MPI programs, communicator management and neighbourhood collectives. We also look at performance aspects such as which MPI routines to use for scalability, MPI internal implementation issues and overlapping communication and calculation. Intended learning outcomes

Understanding of how internal MPI implementation details affect performance
Techniques for overlapping communications and calculation
Knowledge of MPI memory models for RMA operations
Understanding of best practice for MPI+OpenMP programming
Familiarity with neighbourhood collective operations in MPI
