Bringing NVIDIA GPUs to the PGAS/OpenSHMEM World: Challenges and Solutions
Abstract:
Learn about techniques and solutions that bring GPU computing to the World of Partitioned Global Address Space (PGAS) Models, especially with the emerging OpenSHMEM paradigm. PGAS models are gaining attention for providing shared memory abstractions that make it easy to develop parallel applications with dynamic and irregular communication patterns. However, the existing OpenSHMEM standards do not support direct communication on GPU memory. This talk discusses simple extensions to the OpenSHMEM model to address this issue. Challenges and solutions in designing CUDA-aware runtimes to support these extensions, optimize data movement using CUDA IPC and GPUDirect RDMA features are presented. The impact of these concepts on applications performance is demonstrated.
