新的稀疏注意力方法通过联合子空间稀疏注意力提高了LLM长上下文解码吞吐量

研究人员开发了联合子空间稀疏注意力(JSSA),这是一种提高长上下文语言模型解码效率的新方法。JSSA通过学习共享的低维查询-键子空间以获得更好的排序,并实现无收集操作(gather-free)的内核以高效检索令牌,从而解决了令牌级选择的挑战。该方法在保持与全KV注意力相当的准确性的同时,显著提高了解码吞吐量,在128K上下文的NVIDIA B200 GPU上实现了高达6.43倍的提升。 AI

影响 该方法可以显著降低LLM处理长上下文的计算成本,从而实现更高效和可扩展的应用。

    面向高效长上下文解码的联合子空间稀疏注意力

    Sparse attention reduces the KV-cache traffic that dominates long-context LLM decoding, but practical methods largely operate at coarse granularity. Token-level selection offers finer control, yet presents two challenges: low-dimensional scoring may lose query--key structure need…
