This course is an introduction to GPU programming using the directive based OpenACC paradigm. The course consists of lectures and hands-on exercises. Topics covered in the course include basic usage of OpenACC, how to control data movement between CPUs and GPUs, and some more advanced issues related to profiling and interoperability with e.g. MPI.

Learning outcome

After the course the participants should have the basic skills needed for utilising OpenACC with new or existing programs.

Prerequisites and content level

The participants are assumed to have a working knowledge of Fortran and/or C programming languages. In addition, fluent operation in a Linux/Unix environment will be assumed.

The content level of the course is broken down as: beginner’s – 0%, intermediate – 90%, advanced – 10%, community-targeted content – 0%.
