Abstract: In the tutorial, attendees will learn how to leverage the full performance offered by GPU-equipped IBM POWER systems – the architecture which powers the world’s fastest supercomputers Summit and Sierra. The POWER architecture features a powerful CPU which is connected to a number of very powerful NVIDIA GPUs (up to 6) by a tight and fast interconnect called NVLink. OpenACC, a directive-based programming model, can be used to accelerate an application to use all parts of the system. In the tutorial, the POWER architecture and its features are presented. OpenACC is introduced in small steps and used to accelerate a simple serial application in guided hands-on exercises.
