Definition
An AI Cluster is a group of interconnected GPU-accelerated servers designed to work together as a unified computing system for artificial intelligence workloads such as model training, fine-tuning, and large-scale inference. AI clusters rely on high-bandwidth, low-latency interconnects to enable efficient communication between GPUs and compute nodes.
Unlike conventional server clusters, AI clusters are optimized for highly parallel workloads and intensive GPU-to-GPU communication. Their infrastructure typically includes GPU servers, high-speed networking, storage, power distribution, cooling, and cluster management software.
In large-scale deployments, AI clusters may use technologies such as NVLink, InfiniBand, or high-performance Ethernet/RoCE to connect GPUs across servers and racks. These interconnects are critical for maintaining GPU utilization and scaling AI workloads across multiple nodes.
