Description

Advanced MPI

ARCHER, the UK's national supercomputing service, offers training in software development and high-performance computing to scientists and researchers across the UK. As part of our training service we will be running a 2-day Advanced MPI training session.

Trainer

David H David Henty

David teaches on a wide range of EPCC's technical training courses, including MPI and OpenMP, and is overall course organiser for EPCC's MSc in High Performance Computing.

Details

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 communicator management, non-blocking and neighbourhood collectives, single-sided MPI and the new MPI memory model. We also look at performance aspects such as which MPI routines to use for scalability, overlapping communication and calculation and MPI internal implementation issues.

Intended learning outcomes

Understanding of how internal MPI implementation details affect performance
Familiarity with neighbourhood collective operations in MPI
Knowledge of MPI memory models for RMA operations
Familiarity with MPI RMA operations and single-sided communication
Understanding of best practice for MPI+OpenMP programming

Pre-requisites

Attendees should be familiar with MPI programming in C, C++ or Fortran, e.g. have attended the ARCHER MPI course.

Pre-course setup

All attendees should bring their own wireless-enabled laptop set up with the required software. Practical exercises will be done using a guest account on ARCHER.

Timetable

All sessions will include hands-on practical exercises in addition to lectures material.
