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 gives an introduction to GPU programming using HIP. Topics covered in the course include concepts specific to GPUs and GPU programming, writing of GPU kernels, performance considerations, profiling tools, and how to use multiple GPUs together with MPI.

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.

Learning outcome

After the course, the participants will be able to write simple GPU programs, know how to analyse the performance of their GPU programs, and understand how to combine GPUs with MPI.

Prerequisites and content level

The participants are assumed to have a working knowledge of the C++ (or C) programming language and to be familiar with MPI.

The content level of the course is broken down as: beginner's - 0%, intermediate - 60%, advanced - 40%, community-targeted content - 0%.
