Echo: Error-Compensated 4-Bit Tensor-Parallel Communication for LLM Training and Inference
arXiv:2610.14277v1 Announce Type: new Abstract: Tensor parallelism ends every layer with an all-reduce that sits between two dependent matrix multiplications, so its cost cannot be hidden and grows as compute outpaces interconnect...
