A new research paper introduces HCRMap, a framework designed to optimize inference for Mixture-of-Experts (MoE) large language models on 3.5D chiplet systems. HCRMap addresses the issue of expert hotness skew, where certain experts receive a disproportionate amount of tokens, by dynamically managing expert replicas across different memory tiers. This approach aims to mitigate bottlenecks in communication, memory bandwidth, and execution queues. Experiments demonstrate that HCRMap significantly reduces end-to-end latency compared to existing methods like Hydra++, MoEntwine, and PIMoE. AI
IMPACT This research could lead to more efficient and faster inference for large language models on specialized hardware architectures.
