  • 用神经预测器分析提示、设备和模型特征,实现智能调度
  • 在真实集群上将尾延迟降低61.5%,吞吐量提升至原有2倍
  • 适合需要低延迟的多智能体应用,如代码生成与深度研究

智能体类AI应用通过组合多个模型调用和工具执行,对GPU-CPU集群带来新的调度挑战。其推理时间和模型调用结构常依赖于提示语义,导致传统调度方法难以满足低延迟需求。本文提出SwarmX系统,实现面向低延迟智能体应用的智能调度。SwarmX采用专为调度设计的神经预测器,捕捉提示、设备、运行时及目标模型特征;向路由器和缩放器暴露分布预测,支持尾部延迟感知决策;并提供预测器训练与在线适应机制。这些组件集成于调度智能体框架中,可与现有调度与模型服务基础设施无缝融合。我们在近一千台GPU和一百万核CPU的生产部署环境,以及128台GPU的测试平台进行评估。在多智能体代码生成、深度研究和多模态智能体工作流中,SwarmX相比当前最优调度器将尾延迟降低高达61.5%,并在相同SLO下实现生产调度器两倍的吞吐量。

原文摘要 · Abstract (English)

Agentic AI applications compose multiple model calls and tool executions, creating new scheduling challenges for GPU-CPU clusters. Their inference time and model-call structure often depend on prompt semantics, making conventional scheduling approaches ineffective for low-latency serving. This paper presents SwarmX, a system that implements agentic scheduling for low-latency agentic applications. SwarmX uses scheduling-specific neural predictors to capture prompt, device, runtime, and target-model features; exposes distributional predictions to routers and scalers for tail-aware decisions; and provides mechanisms for predictor training and online adaptation. These predictors and mechanisms are integrated into a scheduler-agent framework that provides a common substrate for integration with existing scheduling and model-serving infrastructure. We evaluate SwarmX using production deployment (nearly one thousand GPUs and one million CPU cores) and controlled experiments on a 128-GPU testbed. Across multi-agent code generation, deep research, and multimodal agentic workflows, SwarmX reduces tail latency by up to 61.5% compared to state-of-the-art schedulers and sustains up to 2x the throughput of production schedulers under the same SLO.
