FlashQuant: Sparse-Dense Fusion for Memory-Efficient Outlier-Aware LLM Inference

FlashQuant fuses the dense GEMM and sparse outlier SpMM paths into a single GPU kernel, enabling on-chip reuse of activation and output tiles across heterogeneous computations, and introduces three key techniques: sparse-dense tiling, which aligns outlier processing with dense GEMM tiles, and pipelined scheduling, whic...
