SuperPoD Flex 机型和UBL128组网方案
华为向DeepSeek团队提供了联合定义的昇腾超节点SuperPoD Flex 和UBL128组网方案,可实现128卡3.2Tbps单层交换Scale-up网络和256K卡两层交换Scale-out网络,可以支持超低时延推理和前沿基座模型的大规模训练的需求。基于全互联的UBL128超节点,昇腾提供了 ASC-COMM 高性能自定义通信编程库,支撑用户通信算子与通算融合算子高性能编程。Deepseek团队开发了高性能 DeepEP 通信库,涵盖EP / CP / PP / FSDP 等模式下的通信算子,为更大模型向更大集群扩展提供支持,互联带宽实测达到 Dispatch 375 GB/s、Combine347 GB/s的通信性能,接近硬件上限。
联合创新的成果在CANN社区开源
为支持广泛的开发者基于昇腾 950 及超节点集群部署 DeepSeek模型,华为将此次联合创新的成果在CANN社区开源,包括大EP低延时推理部署、单卡/单机部署、大规模训练、超长文本KVcache池化与 Agentic RL。其中面向大规模推理场景,基于EP32部署策略,offline推理模式下DeepSeek-V4.1-Flash不带框架纯模型性能可实现TPOT=5ms,每卡输出吞吐2469 tokens/s;TPOT=10ms,每卡输出吞吐5102 tokens/s。

基承其本,算展其用。华为昇腾平台将与Deepseek等前沿模型团队,持续深耕芯模协同,联合创新。以AI算力底座承载模型能力,深度适配,双向奔赴,打通推理到训练的全链路,携手打造开放、高效、易用的AI软件生态。
