On-Demand Ray Clusters in ML Workflows via KubeRay & Sematic

September 18, 3:00 PM - 3:15 PM
View Slides

It can often be useful to leverage short-lived Ray clusters as a part of a broader ML workflow (ex: to perform distributed training as part of a pipeline with multiple data and modeling steps). Using these single-purpose, ephemeral Ray clusters can unlock opportunities for improved reproducibility, efficiency, and observability. KubeRay provides a natural way to manage these ephemeral Ray clusters on Kubernetes. Sematic (https://sematic.dev) shares learnings from leveraging KubeRay & Ray in this way.
