  • TLDR:SAC is proposed, the first efficient disaggregated KV cache system optimized for sparse attention models, which leverages the low-latency, cache-line granularity load/store semantics of Compute Express Link (CXL), establishing CXL-based disaggregation as the superior infrastructure for emerging sparse attention models.

  • 标题中文:SAC:面向稀疏注意力 LLM 与 CXL 的解耦 KV Cache 系统
  • TLDR中文:提出 SAC,这是首个针对稀疏注意力模型优化的高效解耦 KV Cache 系统,利用 CXL(Compute Express Link)的低延迟、cache-line 粒度 load/store 语义,将基于 CXL 的解耦确立为新兴稀疏注意力模型的优越基础设施。
