vLLM Office Hours - Distributed Inference with vLLM - January 23, 2025
In this session, we explored the motivation for distributed inference, delving into vLLM architecture and GPU parallelism to enhance performance. We discussed the challenges of serving large models, introduced the concept of tensor parallelism, and examined the benefits and trade-offs of leveraging multiple GPUs for inference. We also highlighted profiling tools for analyzing kernel performance and overhead, along with the potential challenges of adopting a disaggregated approach with separate nodes for prefill and decoding.
During the open discussion, we addressed various community questions, including practical applications of tensor parallelism in real-world scenarios, the impact of distributed inference on latency and throughput, and strategies for optimizing multi-GPU setups.

vLLM Office Hours - Disaggregated Prefill and KV Cache Storage in vLLM - November 14, 2024
In this session of our bi-weekly vLLM office hours, we explored the potential of disaggregated prefill and KV cache storage in vLLM to enhance distributed inference. We discussed the initial PR on disaggregated prefill and how KV cache sharing across vLLM improves performance through faster delivery and the composition of multiple KV caches. These advancements are designed to push the boundaries of distributed inference efficiency.
The Q&A session included topics such as the practical gains of improving KV cache transmission and its impact on throughput. We explored comparisons between vLLM's implementation and other approaches like NCCL and addressed questions on KV cache buffer reuse, hardware configurations, and the trade-offs of compression and memory allocation. Other Q&A highlights included the influence of disaggregation on selective prefill logic, the potential for semantic caching improvements, and challenges in combining disaggregated prefill with automatic prefix caching.
