New research optimizes sparse attention for LLMs with QUILT and PageWeaver

By PulseAugur Editorial · [2 sources] ·

Two new research papers, QUILT and PageWeaver, propose novel methods to optimize sparse attention mechanisms in large language models. QUILT introduces a workload-aware execution strategy that reuses shared KV entries across neighboring queries, reducing memory traffic and computation, leading to significant reductions in kernel latency and time-to-first-token. PageWeaver focuses on KV-guided query unions to assemble query groups efficiently on GPUs, achieving substantial speedups over existing methods and improving prefill throughput. AI

IMPACT These new techniques could significantly improve the efficiency and speed of large language models, particularly for tasks requiring long context understanding.

    QUILT: Rethinking Sparse-Attention Prefill through Shared Query Execution

    arXiv:2610.11134v1 Announce Type: new Abstract: Sparse attention reduces the cost of long-context attention, but existing kernels typically process queries independently, repeatedly loading and dequantizing KV entries shared across queries. We observe substantial overlap in the K…

    PageWeaver: KV-Guided Query Unions for Sparse Attention

    arXiv:2610.11201v1 Announce Type: cross Abstract: Dynamic sparse attention limits the KV pages selected by each query, but a small support does not necessarily yield efficient GPU work. Query unions share page loads and populate Tensor Core tiles; their cost depends on which quer…
