Federation of Experts: Communication Efficient Distributed Inference for Large Language Models

The paper introduces Federation of Experts (FoE), a new architecture that reorganizes the mixture-of-experts (MoE) block in transformer layers into multiple MoE clusters. Each cluster handles a single KV head, and expert parallelism is applied within clusters while a sum operation synchronizes post‑attention residuals across clusters. FoE eliminates all‑to‑all communication on a single GPU and limits it to intra‑node communication in multi‑node setups, leading to significant reductions in inference latency and throughput improvements on LongBench.

Pre-Compiled Pipeline Shards for Distributed LLM Inference on Intel AI PC Fleets

The paper presents a method for distributing large language model inference across multiple Intel AI PCs by splitting the model into pipeline shards, each pre‑compiled into an OpenVINO graph. Three key techniques—beam_idx Gather to enable GPU optimizations, speculative decoding on stateful models, and interleaved micro‑batching—allow a two‑node Llama 3.1 8B INT4 pipeline to serve two users at 1.79× the throughput of a single‑node model, while a four‑node deployment can run a 70B model that no single PC can hold. The authors provide code, benchmark logs, and reproduction scripts on GitHub.

Agora: Collective and Permissionless Internet-Scale Pretraining of Large Language Models

arXiv:2607. 13332v1 Announce Type: new Abstract: Training large language models at the multi-billion to trillion parameter scale is confined to datacenters, where data-parallel (DP) and model-parallel (MP) techniques presume homogeneous accelerators, high-speed interconnects, and a single orchestrating entity.
