Description

This course gives a thorough introduction to programming GPUs using the directive based OpenACC paradigm. The course consists of lectures and hands-on exercises. Topics of this course include the basic usage of OpenACC, as well as some more advanced issues related to profiling, performance and interoperability with CUDA.

Learning outcome

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

Prerequisites

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.
