新的分片方法加速 Transformer 模型蒸馏

研究人员开发了一种名为面向延迟张量并行性的亲和感知分片(Affinity-Aware Sharding for Delayed Tensor Parallelism, DTP)的方法,以提高 Transformer 模型推理的效率。该技术通过允许设备在收集其他部分输出之前处理和广播部分输出,解决了标准张量并行性中的阻塞 all-reduce 问题。研究表明,通过置换模型以最大化同一设备上 KV 头部和 FFN 神经元之间的亲和力,DTP 模型的再训练或蒸馏过程得到了显著加速。这种优化过程在单 GPU 上对 Qwen3-0.6BDanube3-500M 等模型进行优化,耗时不到两分钟,与朴素布局相比,优化后的布局在蒸馏目标上所需的步数减少了一半到三分之二。 AI

影响 这项研究通过减少计算瓶颈,可能导致更高效的大型语言模型的训练和推理。
