This course will be delivered as an ONLINE COURSE for remote participation due to the COVID-19 measures enforced by most European governments.
The course introduces the basics of parallel programming with the OpenMP paradigm, and discusses how to combine OpenMP with MPI. OpenMP is a threading based approach which enables one to parallelize a program over a single shared memory machine, such as a single node in Mahti, Puhti or LUMI (CPU partition). By using OpenMP together with MPI, parallel scalability with large number of nodes can be improved. The course consists of lectures and hands-on exercises on parallel programming.
This course is part of CSC Autumn of HPC 2021, a set of five two day modules teaching essential skills in parallel programming for modern GPU-accelerated supercomputers and organised by CSC – IT Center for Science Ltd (Finland) under PRACE Training Centres activity.
After the course the participants should be able to write simple parallel programs and parallelize existing programs with basic features of OpenMP, combine OpenMP, and understand also more advanced OpenMP topics such as OpenMP Tasks.
Prerequisites and content level
