You are managing a Kubernetes cluster running AI training jobs using TensorFlow.

Comprehensive and Detailed Explanation From Exact Extract:

For distributed AI training jobs that require fast inter-node communication, such as those using TensorFlow across multiple GPUs and nodes,InfiniBand networkingis the preferred solution. InfiniBand provides ultra-low latency and high bandwidth, reducing communication delays significantly and increasing overall training throughput. While jumbo frames on Ethernet can help, they do not match the performance of InfiniBand. Dedicated storage networks or increasing replicas do not directly address inter-node communication latency.
