New AI scheduler SCALE generalizes to unseen cluster sizes

Researchers have developed SCALE, a new deep reinforcement learning scheduler designed for agentic LLM systems that can manage tasks across heterogeneous clusters of varying sizes. Unlike previous schedulers that require retraining for different cluster configurations, SCALE uses a cross-attention pointer network to generalize to unseen cluster scales without fine-tuning. By incorporating Structured Representation Regularization (SRR), which includes a decorrelation loss and a KL penalty, SCALE maintains stable feature statistics and achieves an 8.9% reduction in average response time when tested on larger clusters than it was trained on.

    SCALE: Scalable Cross-Attention Learning with Extrapolation for Agentic Workflow Scheduling

    arXiv:2606.06820v1 Announce Type: cross Abstract: Agentic Large Language Model (LLM) systems decompose complex tasks into workflow Directed Acyclic Graphs (DAGs) whose primitives must be scheduled on heterogeneous clusters. Existing deep reinforcement learning (DRL) schedulers ar…
