arXiv:2606.10445v1 Announce Type: cross Abstract: Semi-structured 2:4 sparsity is widely supported by modern accelerators, providing up to a 2x theoretical speedup. However, its strict 50% sparsity constraint often causes non-negligible accuracy degradation under post-training pruning. Meanwhile, existing relaxed sparsity formats either require specialized compiler support or introduce runtime overheads that limit end-to-end speedup. We propose Spense, a practical hybrid sparse-dense format that splits each weight matrix into a 2:4 sparse region and a dense region. This design relaxes the effe
The increasing scale and computational demands of LLMs are driving an urgent need for more efficient inference methods, making practical sparsity techniques critical for deployment.
This breakthrough offers significant computational efficiency in AI inference by enabling sparse and dense operations, directly impacting deployability and cost-effectiveness of large language models.
The ability to achieve speedups with practical one-shot pruning, addressing accuracy degradation and runtime overheads, changes the calculus for LLM deployment on accelerators.
