Coupling GPUDirect RDMA and InfiniBand Hardware Multicast Technologies for Streaming Applications
Abstract:
Learn recent developments in middleware design to boost performance of GPU-based streaming applications. Several runtimes already support and optimize GPU communication using various CUDA features. Similarly, some runtimes use InfiniBand hardware multicast to boost broadcast performance for host-based communications. We'll focus on challenges in combining and fully utilizing GPUDirect RDMA and hardware multicast technologies in tandem to design support for high-performance broadcast operation for streaming applications. Further, we'll present associated challenges and designs for clusters with multi-HCA and multi-GPU configurations and MPI_Bcast operations performance evaluation of the proposed designs will be presented and analyzed.
