UB-Mesh: A Cost-Efficient, Scalable Network Architecture for Large-Scale LLM Training

As LLMs scale, their computational and bandwidth demands increase significantly, posing challenges for AI training infrastructure. Following scaling laws, LLMs improve comprehension, reasoning, and generation by expanding parameters and datasets, necessitating robust computing systems. Large-scale AI clusters now require tens of thousands of GPUs or NPUs, as seen in LLAMA-3’s 16K GPU training setup, which took 54 days. With AI data centers deplo…
