This course gives an introduction to programming GPUs using the directive based OpenACC paradigm. The course consists of lectures and hands-on exercises. The course covers the basic usage of OpenACC, as well as some more advanced topics related to profiling, performance, interoperability with CUDA and multi-GPU programming.

During the last day there is also an opportunity to discuss your own code with the lecturers, and to investigate possibilities for porting your own code to OpenACC.

Learning outcome

After the course the participants should have the basic skills needed for utilizing OpenACC in new, or existing programs.


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