Advanced OpenMP PrerequisitesNew
Description
- Please note that although this course is being hosted at Cambridge, it is being organised and run by EPCC at the University of Edinburgh.
- OpenMP is the industry standard for shared-memory programming, which enables serial programs to be parallelised using compiler directives.
- 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.
- Access will be given to appropriate hardware for all the exercises, although many of them can also be performed on a standard Linux laptop.
