BlockServe framework boosts dLLM serving throughput by up to 10.6x

Researchers have developed BlockServe, a novel framework designed to improve the efficiency of serving diffusion large language models (dLLMs). This system addresses the challenge of heterogeneous convergence rates in batch processing by implementing block-grained scheduling, which allows for the immediate eviction of completed requests at block boundaries. BlockServe also incorporates mixed-state execution and a compute-aware admission controller to expand batch capacity. Experiments on Dream and LLaDA benchmarks show that BlockServe can achieve significantly higher throughput compared to existing methods like Fast-dLLM++ while maintaining generation quality. AI

IMPACT This research offers a new method for optimizing dLLM inference, potentially leading to more efficient and cost-effective deployment of these models.

    BlockServe: Block-Grained Continuous Batching for High-Throughput Diffusion LLM Serving

    Efficient serving of diffusion large language models (dLLMs) is hindered by convergence heterogeneity: when batching multiple requests, different sequences converge at different rates, causing faster requests to stall behind slower stragglers and introducing compute bubbles and t…
