S8351 - MultiGPU Made Easy by OmpSs + CUDA/OpenACC

Session Speakers
Session Description

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 which may be combined with CUDA, and recently with OpenACC as well. Using OpenACC we will start benefiting from GPU computing, obtaining great coding productivity and nice performance improvements. 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.
