Researchers have introduced TACO, a novel framework designed to enhance the efficiency of training large-scale tensor-parallel Large Language Models (LLMs). TACO addresses communication overhead by employing an FP8-based compression strategy for intermediate tensors, utilizing data-driven reshaping and an Adaptive Scale-Hadamard Transform for high-fidelity quantization. The framework also features a fused compression operator to reduce memory traffic and kernel launch times, enabling better overlap with communication. Experiments with GPT and Qwen models showed TACO can improve end-to-end throughput by up to 1.87 times with minimal accuracy loss. AI
