Expanse Webinar: GPU Computing and Programming on Expanse

This webinar provides a brief introduction to massively parallel computing with graphics processing units (GPUs) on the SDSC Expanse supercomputer. The use of GPUs is becoming increasingly popular across all scientific domains both for traditional simulations and AI applications since GPUs can significantly accelerate time to solution for many computational tasks. In this webinar, participants will learn how to access Expanse GPU nodes, how to launch GPU jobs on Expanse, and get introduced to GPU programming. The webinar will cover the essential background of GPU chip architectures and the basics of programming GPUs with the NVIDIA HPC SDK via the use of libraries, OpenACC compiler directives, and the CUDA programming language. We will also briefly discuss performance analysis with NVIDIA Nsight profilers. Participants will thus acquire the foundation to use and develop GPU aware applications.
