Strait: Perceiving Priority and Interference in ML Inference Serving
Strait addresses a critical pain point in production ML serving: scheduling inference requests across GPUs when multiple priority tiers and tight latency budgets collide. The system models GPU contention during data movement and kernel interference to predict latency more accurately, then uses those predictions to enforce deadline-aware scheduling. This matters because on-premises ML deployments increasingly need to run mixed workloads (high-priority, low-latency queries alongside batch jobs) on shared hardware without sacrificing SLA compliance. Better latency forecasting under contention directly improves utilization and cost efficiency for enterprises running inference at scale.58
