Idea
Autoscaling platform optimizing heterogeneous hardware for large language model inference, improving efficiency for AI service providers
Research Paper
Core Innovation
This paper introduces HeteroScale, a coordinated autoscaling framework that integrates a topology-aware scheduler with a metric-driven policy to balance prefill and decode stages in disaggregated LLM serving. Unlike prior work, it efficiently manages heterogeneous hardware and network constraints to significantly boost GPU utilization and reduce operational costs.

Research Paper Overview
Taming the Chaos: Coordinated Autoscaling for Heterogeneous and Disaggregated LLM Inference
Summary
HeteroScale is a coordinated autoscaling framework designed for Prefill-Decode disaggregated LLM serving architectures. It uses a topology-aware scheduler and a novel metric-driven policy to efficiently manage heterogeneous hardware and network constraints, balancing prefill and decode stages. Deployed at scale, it significantly improves GPU utilization by 26.6 percentage points and saves hundreds of thousands of GPU-hours daily while maintaining service level objectives.
