Advanced MPI @ EPCC at Cambridge

Sep 12, 2017, 9:00 AM → Sep 13, 2017, 5:00 PM Europe/London

Titan 1 (University of Cambridge)

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, and in conjunction with INTERTWinE, we will be running a 2 day ‘Advanced MPI’ training session.

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, MPI-IO, 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.  Timetable will be available nearer the course date.

This course is now fully booked.

This course is free to all academics.

Intended learning outcomes

• Understanding of when and how to use MPI datatypes
• Understanding of how to achieve high performance with MPI I/O
• 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 the challenges of hybrid MPI+X programming
• Understanding of best practice for MPI+OpenMP programming
• Familiarity with proposal to add flexible endpoints in MPI

 

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.
