Protocol Models: Scaling Decentralized Training with Communication-Efficient Model Parallelism
arXiv:2506.01260v2 Announce Type: replace Abstract: Scaling models has led to significant advancements in deep learning, but training these models in decentralized settings remains challenging due to communication bottlenecks. While existing compression techniques are effective in data-parallel, they do not extend to model parallelism. Unlike data-parallel training, where weight gradients are exchanged, model-parallel requires compressing activations and activation gradients as they propagate through layers, accumulating compression errors. We propose a novel compression algorithm that compres
The increasing scale of AI models and the rising cost and energy demands of centralized training necessitate more efficient decentralized methods to sustain AI development.
Efficient decentralized training can democratize access to AI model development, reduce reliance on mega-datacenters, and potentially mitigate communication bottlenecks in large-scale AI research.
The ability to scale model parallelism effectively in decentralized settings, including compression of activations and gradients, could lead to more distributed AI compute infrastructure.
