Mellanox FDR InfiniBand with NVIDIA GPUDirect RDMA
Mellanox Technologies FDR InfiniBand system has support for NVIDIA GPUDirect remote direct memory access (RDMA) technology. The NVIDIA GPUDirect technology provides application performance and efficiency for GPU-accelerator based high-performance computing (HPC) clusters. NVIDIA GPUDirect RDMA technology dramatically accelerates communications between GPUs by providing a direct peer-to-peer communication data path between scalable HPC adapters and NVIDIA GPUs. This capability provides a significant decrease in GPU-GPU communication latency and completely offloads the CPU and system memory subsystem from all GPU-GPU communications across the network.
