Distributing LLM Inference in DwarfStar

Antirez introduces DwarfStar, a prototype system for distributing LLM inference across multiple nodes. The approach partitions the model's layers across machines, using a fan-out pattern where a coordinator sends tokens to all layer groups in parallel during prefill, reducing inference latency. DwarfStar is designed to run on low-end hardware, aiming for cost-effective, decentralized inference.
