arXiv:2606.11081v1 Announce Type: new Abstract: Communication-efficient pre-training of LLMs is increasingly important as training draws on compute distributed across clusters, data centers, and lower-bandwidth links. Many practical methods reduce communication frequency but still rely on synchronous All-Reduce operations that maintain identical model states and tie progress to global collectives. This can become a bottleneck when bandwidth or worker speed is heterogeneous. We introduce GASLoC, a novel decentralized pre-training algorithm that generalizes the notion of communication accelerati
The increasing scale and complexity of LLMs, coupled with distributed compute infrastructures, necessitate more efficient pre-training methods to overcome communication bottlenecks.
This research addresses a critical bottleneck in LLM pre-training, which, if scaled, can significantly reduce training costs, accelerate model development, and broaden access to advanced AI capabilities.
The introduction of GASLoC suggests a shift towards more decentralized, communication-efficient pre-training algorithms for LLMs, moving away from synchronous All-Reduce operations.

- · Organizations with distributed and heterogeneous compute resources
- · Traditional synchronous communication protocols
- · LLM developers reliant on tightly coupled, homogeneous clusters
More efficient LLM pre-training could decrease the cost and time required to develop large AI models.
Reduced training costs may enable a wider range of organizations to develop or fine-tune state-of-the-art LLMs, decentralizing AI development.
Increased accessibility to advanced LLMs could accelerate the proliferation of AI agents and applications across various sectors.
