OpenMP is the industry standard for shared-memory programming, which enables serial programs to be parallelised using compiler directives.This course is aimed at programmers seeking to deepen their understanding of OpenMP and explore some of its more recent and advanced features.

This 3-day course will cover topics including nested parallelism, OpenMP tasks, the OpenMP memory model, performance tuning, hybrid OpenMP + MPI, OpenMP implementations, and new features in OpenMP 4.0/4.5. Hands-on practical programming exercises make up a significant, and integral, part of this course.

Attendees should be familiar with the basics of OpenMP, including parallel regions, data scoping, work sharing directives and synchronisation constructs. Access will be given to appropriate hardware for all the exercises, although many of them can also be performed on a standard Linux laptop.


Pre-course setup

All attendees should bring their own wireless-enabled laptop set up with the standard software as detailed on our site http://www.archer.ac.uk/training/courses/software.php. The course tutor will be able to assist with settings to connect on the day.

Practical exercises will be done using a guest account on ARCHER. . You should also have a web browser, a pdf reader and a simple text editor.
