AI总结:

针对现有深度学习GPU集群调度器缺乏语义感知导致的性能问题,提出SchedMate框架,通过三个LLM组件从非结构化数据提取语义信息,非侵入式增强现有调度器,实验显示最多可将平均作业完成时间缩短1.91倍。

摘要:

深度学习(DL)调度器对优化GPU集群的资源分配至关重要,但存在一个关键局限:它们基本无法感知所管理作业的语义上下文。这迫使调度器依赖有限的元数据,导致性能剖析开销高、时长估计不可靠、故障处理不足以及可观测性差。为此,我们提出SchedMate框架,通过系统地从被忽视的非结构化数据源(源代码、运行时日志、历史作业)中提取深度洞察,弥补这一语义鸿沟。SchedMate通过三个基于大语言模型(LLM)的组件,以非侵入式方式增强现有调度器。我们的实现可与现有深度学习调度器无缝集成。在128-GPU物理集群上的评估以及基于生产轨迹的大量仿真表明,SchedMate将平均作业完成时间最多缩短1.91倍,大幅提升了调度性能,证明了语义感知在现代深度学习调度中的关键作用。

英文摘要:

Deep learning (DL) schedulers are pivotal in optimizing resource allocation in GPU clusters, but operate with a critical limitation: they are largely blind to the semantic context of the jobs they manage. This forces them to rely on limited metadata, leading to high profiling overhead, unreliable duration estimation, inadequate failure handling, and poor observability. To this end, we propose SchedMate, a framework that bridges this semantic gap by systematically extracting deep insights from overlooked, unstructured data sources: source code, runtime logs, and historical jobs. SchedMate enhances existing schedulers non-intrusively through three LLM-based components. Our implementation integrates seamlessly with existing deep learning schedulers. Evaluations on a 128-GPU physical cluster and extensive simulations on production traces show SchedMate reduces average job completion times by up to 1.91x, substantially enhancing the scheduling performance, demonstrating the critical role of semantic-awareness in modern DL scheduling.
