    Panmai 920 Debuts, Closing the Loop on T-Head's Computing and Storage Network

    <p>“在网络结构未充分优化的情况下，<strong>大规模AI集群的GPU利用率通常仅维持在30%—40%区间。”</strong>平头哥产品总监李旭慧表示。</p><p>算力集群本质上是一个强同步系统：上千张GPU需要在同一时间完成计算并交换数据。一旦某个节点通信出现延迟，整个集群的计算进程就会被迫等待，<strong>系统效率最终由最慢路径决定。</strong></p><p>当集群规模进一步扩展，网络瓶颈被进一步放大：突发推理流量带来的数据洪峰、复杂拓扑导致的链路拥塞，以及依赖系统级PCIe总线所形成的长数据路径，都在不断侵蚀算力效率。</p><…
