Celty: SpMspV GPU Kernel and SIMT Co-Design for Efficient Dual-Sparse LLM Inference

Celty, a co-designed sparse format, GPU kernel, and SIMT microarchitecture for efficient spMspV in LLM inference is proposed, which introduces a Run-Length Compressed CSC format that enables vectorized loading of compressed weight columns and exploits both sparsity sources to skip unnecessary memory accesses.

KronQ: LLM Quantization via Kronecker-Factored Hessian

KronQ, a PTQ framework that challenges the assumption that all output channels contribute equally to the layer-wise reconstruction objective by introducing the gradient covariance into the quantization pipeline, and introduces bidirectional incoherence processing.
