This Bootcamp will cover scaling applications to multiple GPUs across multiple nodes. Doing so requires one to be adept at programming models and optimization techniques, and proficient at performing root-cause analysis using in-depth profiling to identify and minimize bottlenecks. The N-Ways to Multi-GPU Programming Bootcamp covers step-by-step ways to improve application performance using cues from profilers and provides an understanding of the underlying technologies and communication topology needed to leverage powerful NVIDIA® libraries to extract more performance from the system.
The Bootcamp is co-organised by HLRS, JSC, LRZ, VSC Vienna, Cyfronet AGH, IT4Innovations, RISE, LiU, OpenACC.org and NVIDIA for EuroCC Austria, EuroCC Czechia, EuroCC Poland, EuroCC Montenegro, SLING, EuroCC@GCS and EuroCC Sweden, all National Competence Centres for High-Performance Computing.
