BOOTCAMP: N-Ways to GPU Programming

This Bootcamp will be held online with Zoom.

During this two-day online Bootcamp, participants will learn about multiple GPU programming models and will be able to choose the one that best fits their needs to run their scientific codes on GPUs. This Bootcamp will cover an introduction to GPU programming using OpenACC, OpenMP, stdpar and CUDA, and will provide hands-on opportunities to learn how to analyse GPU-enabled applications using NVIDIA® Nsight™ Systems. This online Bootcamp is a hands-on learning experience where you will be guided through step-by-step instructions with teaching assistants on hand to help throughout.

The Bootcamp is co-organised by HLRS, JSC, LRZ, VSC, and NVIDIA for EuroCC Austria and EuroCC@GCS, the Austrian and German National Competence Centres for High-Performance Computing.
