The Multi-GPU Programming Bootcamp will be hosted virtually for one and a half days on June 17-18. Scaling applications to multiple GPUs across multiple nodes requires one to be adept at not just the programming models and optimization techniques, but also at performing root-cause analysis using in-depth profiling to identify and minimize bottlenecks. In this Bootcamp, participants will learn to improve the performance of an application step-by-step, taking cues from profilers along with the ways.
This bootcamp is co-organized by the Vienna Scientific Cluster (VSC), IT4Innovations National Supercomputing Center (IT4I), High-Performance Computing Center Stuttgart (HLRS), Jülich Supercomputing Centre (JSC), Leibniz Supercomputing Centre (LRZ), University of Donja Gorica (UDG), Academic Computer Centre Cyfronet AGH (Cyfronet), Linköping University (LiU), Research Institutes of Sweden (RISE), HPC Vega at IZUM (IZUM), OpenACC organization, and NVIDIA for EuroCC Austria, EuroCC Czechia, EuroCC@GCS, EuroCC Montenegro, EuroCC Poland, EuroCC Sweden, and EuroCC Slovenia, all National Competence Centres for High-Performance Computing.
