RDMA for GPUDirect - Interconnect Optimizations for High Performance Computing (Presented by Mellanox)
Abstract:

GPU-based clusters are being adopted at a rapid pace in high performance computing clusters to perform compute-intensive tasks at large scale. One of the main performance challenges in the deployments of this GPU-based clusters is the performance and latency of communications between GPUs across the interconnect fabric. The goal of this session is to highlight interconnect optimizations such as RDMA for GPUDirect, which provides for higher performance and better utilization for GPU communications by allowing the network adapter and the GPU to directly communicate in a peer-to-peer fashion, completely bypassing the CPU subsystem. We will show the benefits of using this new technology and explain how registrants can utilize this new features in their own compute clusters.
