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 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.
This course is free to all academics.
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. Practical exercises will be done using a guest account on ARCHER. You will need an ssh client such as terminal on a Mac or Linux machine, or putty or MobaXterm on Windows. The course tutor will be able to assist with settings to connect on the day. You should also have a web browser, a pdf reader and a simple text editor.
