High-Performance Computing Center Stuttgart

BOOTCAMP: N-Ways to GPU Programming

During this two-day online Bootcamp, four different GPU programming models will be introduced and participants 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.

This bootcamp is co-organized by the National Competence Centres for Supercomputing in Austria (ACA), Germany (SIDE), and Poland (NCC-PL) together with their supercomputing centres Austrian Scientific Computing (ASC), High-Performance Computing Center Stuttgart (HLRS), Leibniz Supercomputing Centre (LRZ), Jülich Supercomputing Centre (JSC), Academic Computer Centre Cyfronet AGH (Cyfronet), and OpenACC organization and NVIDIA.
