L7106 - Best GPU Code Practices Combining OpenACC, CUDA, and OmpSs

Session Speakers
Session Description

We'll guide you step by step to port and optimize an oil-and-gas mini application to efficiently leverage the amazing computing power of NVIDIA GPUs. While OpenACC focuses on coding productivity and portability, CUDA enables extracting the maximum performance from NVIDIA GPUs. OmpSs, on the other hand, is a GPU-aware task-based programming model that may be combined with CUDA, and recently with OpenACC as well. Using OpenACC, we'll start benefiting from GPU computing, obtaining great coding productivity, and a nice performance improvement. We can next fine-tune the critical application parts developing CUDA kernels to hand-optimize the problem. OmpSs combined with either OpenACC or CUDA will enable seamless task parallelism leveraging all system devices. Prerequisites: Basic knowledge of OpenACC and CUDA. This lab utilizes GPU resources in the cloud, you are required to bring your own laptop.
