華爲FlashComm技術助力大模型推理提速80%
在全球人工智能發展的浪潮中，模型推理的速度和效率愈發成爲焦點。近期，華爲的數學團隊在 DeepSeek 開源週期間推出了名爲 FlashComm 的新技術，旨在通過三項創新措施，大幅提升大模型推理的性能，最高可達80% 的速度提升。首先，FlashComm 技術重點優化了 AllReduce 通信操作。傳統的 AllReduce 方法就像一輛裝滿貨物的集裝箱車，不夠靈活。華爲團隊通過智能化手段，將數據分爲兩部分:先進行 ReduceScatter，然後再進行 AllGather。這一重組過程使得後續的通信量減少了35%，同時關鍵計算量也減少到
