From the innovative launch of ChatGPT to the sudden rise of deepseek, supercomputing and AI have continuously gained significant global attention and accelerated investment. Data centers worldwide are increasingly adopting NVIDIA GPU-accelerated systems to scale up a variety of AI, HPC, and data analytics applications. The NVIDIA H100 GPU, as the top-performing data center GPU, represents a major leap in supercomputing capabilities. FS, a leading network solutions provider, has introduced H100-based InfiniBand solutions to empower global enterprises with unmatched data center performance and scalability. This article explores how the NVIDIA H100 GPU is reshaping AI and HPC data centers, and how FS's InfiniBand solution optimizes network performance for H100-based systems.NVIDIA H100 GPU Enables Accelerated AI/HPC Data CentersThe NVIDIA H100 Tensor Core GPU, based on the NVIDIA Hopper GPU architecture, is a top-tier computing accelerator that integrates the latest technologies and innovative designs, making it a benchmark product in the fields of AI and HPC. The H100 can securely accelerate a wide range of workloads, from small business tasks to large-scale HPC applications and AI models with trillions of parameters. Manufactured using TSMC's custom 4N process tailored for NVIDIA with 80 billion transistors and numerous architectural advancements, the H100 GPU is one of the most advanced chips in the world. Besides, the NVIDIA H100 GPU features the following groundbreaking innovations:Fourth-generation Tensor Cores deliver faster matrix computations across a wider range of AI and HPC workloads.Transformer Engine allows to achieve up to 9x faster AI training and up to 30x faster AI inference speeds for large language models compared to its predecessor, the A100.NVLink Network Interconnect supports seamless GPU-to-GPU communication across up to 256 GPUs, spanning multiple compute nodes for unparalleled scalability.Secure MIG partitions the GPU into isolated, optimally sized instances, ensuring superior quality of service (QoS) for smaller workloads while maximizing resource efficiency.As the 9th generation data center GPU from NVIDIA, the H100 delivers a significant performance leap for large-scale AI and HPC compared to its predecessor, the NVIDIA A100 GPU. For mainstream AI and HPC models, the H100 with InfiniBand interconnect technology offers up to 30 times the performance of the A100. With the new NVLink switch system, these challenging computing workloads achieve even greater performance gains, in some cases tripling performance over H100 with InfiniBand.NVIDIA DGX H100: The Most Powerful Supercomputing SystemThere are a variety of data center-ready H100-based systems, such as DGX H100, DGX SuperPOD, and HGX H100. Among these, the NVIDIA DGX H100 system is specifically designed to maximize AI throughput, providing enterprises with a powerful, comprehensive platform to tackle the most demanding AI challenges. DGX H100 is cloud-native ready with Bluefield-3, NDR InfiniBand, and second-generation MIG technology. A single DGX H100 system delivers an unparalleled 32 petaFLOPS of performance. By connecting multiple DGX H100 systems into clusters known as DGX PODs or even DGX SuperPODs, performance can be easily scaled to meet growing demands.Inside the DGX H100, 8 NVIDIA H100 GPUs are interconnected using the cutting-edge fourth-generation NVLink technology through 4 third-generation NVSwitches. The system also includes 8 NVIDIA ConnectX-7 InfiniBand/Ethernet adapters, each operating at 400Gb/s, providing a powerful, high-speed fabric for large-scale AI workloads.Furthermore, each DGX H100 is equipped with two NVIDIA BlueField-3 DPUs (Data Processing Units), which enable intelligent hardware-accelerated storage, security, and network management functions. The BlueField-3 DPUs decouple data center infrastructure from business applications, enhancing data center security, simplifying operations, and reducing the total cost of ownership. NVIDIA recommends using Quantum-2 switches with NDR 400Gb/s ports to connect large-scale clusters, such as the DGX H100 system. Each BlueField-3 DPU in DGX H100 system integrates ConnectX-7 network adapters, offering two 400Gb/s ports per DPU. These ports can connect to Quantum-2 InfiniBand switches using high-speed 800G modules, enabling a highly efficient data center network. Powered by the high-speed InfiniBand network, DGX H100 systems achieve exceptional cluster computing and data processing performance. This combination is ideal for applications requiring massively parallel computing and ultra-low-latency communication.FS H100-Based InfiniBand Network SolutionWhile the NVIDIA H100 GPU and DGX H100 system provide the computational power needed for AI and HPC workloads, the network infrastructure plays a critical role in ensuring that data can move efficiently between nodes.
