华为FlashComm技术助力大模型推理提速80%
在全球人工智能发展的浪潮中，模型推理的速度和效率愈发成为焦点。近期，华为的数学团队在 DeepSeek 开源周期间推出了名为 FlashComm 的新技术，旨在通过三项创新措施，大幅提升大模型推理的性能，最高可达80% 的速度提升。首先，FlashComm 技术重点优化了 AllReduce 通信操作。传统的 AllReduce 方法就像一辆装满货物的集装箱车，不够灵活。华为团队通过智能化手段，将数据分为两部分:先进行 ReduceScatter，然后再进行 AllGather。这一重组过程使得后续的通信量减少了35%，同时关键计算量也减少到
