Octoputer 4U with NVLink® – HGX A100

8-GPU server with NVIDIA A100 with NVLink GPUs – HGX A100™

Microway’s Octoputer™ 8-GPU server with NVIDIA NVLink® Technology provides eight NVIDIA A100 Tensor Core GPUs and two 3rd Gen Xeon Scalable Processors within a powerful 4U rackmount server platform. This system is based on the NVIDIA HGX A100 8 GPU platform.

Leveraging NVIDIA’s Unified Memory technology and NVIDIA NVLink GPU interconnect, this system allows your applications to utilize the memory of all eight GPUs combined in a single memory space. The architecture is uniquely suited to AI Training and highly GPU accelerated HPC applications.

Each Octoputer server arrives fully integrated with the operating system of your choice, along with the NVIDIA CUDA toolkit. Your choice of libraries, tools, and software applications are available for an additional fee. All systems pass rigorous stress tests for over 48 hours prior to shipment.

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.
