Benefits of our 8-GPU Server with NVLink

As applications scale across multiple GPUs, it is critical that communications between GPUs be efficient. NVIDIA’s NVLink interconnect provides unprecedented performance compared to PCI-Express connectivity. As shown in the diagram below, all eight GPUs are connected by NVIDIA NVSwitches with 600GB/sec of bandwidth for all-to-all communication. Connections are also provided for full-speed GPU-Direct RDMA transfers as part of a GPU-accelerated HPC cluster.
