Distributed Generative Inference of LLM at Internet Scales with Multi-Dimensional Communication Optimization
New framework cuts latency 43% using multi-dimensional optimization over internet nodes.
Researchers from multiple institutions have unveiled BloomBee, a novel framework for decentralized LLM inference that tackles the primary bottleneck of low cross-node network bandwidth in internet-scale systems. By integrating LLM-layer assignment, micro-batching, and tensor offloading, BloomBee optimizes communication from multiple dimensions simultaneously. The team formulated the coordination of these techniques as an optimization problem solved via dynamic programming, ensuring efficient resource allocation across heterogeneous nodes.
In evaluations across diverse network environments, BloomBee achieved significant performance gains: up to 1.76x improvement in service throughput and a 43.20% reduction in average latency compared to existing decentralized inference systems. Additionally, it incorporates custom lossless compression and speculative decoding tailored for low-bandwidth settings. The framework is open-sourced, offering a cost-efficient alternative to centralized inference for deploying LLMs at scale.
