In this video from the University of Houston CACDS HPC Workshop, Fernanda Foertter from ORNL presents: Leveraging Leadership Computing Facilities: Assisting User’s Transition to Titan’s Accelerated Architecture.
“Geoscientists need tools to allow them to rapidly develop algorithms that run fast on accelerators, while at the same time deliver portability and improve productivity. They demand a single source code, with no need to maintain multiple code paths, using a high-level approach that presents a low learning curve. OpenACC provides directives-based approaches to rapidly accelerating applications for GPUs and other parallel architectures. This talk will serve as an introduction to programming with OpenACC 2.0.”
