What do people build with it?

USE CASE 1

Schedule GPU-parallel machine learning training jobs efficiently on a Kubernetes cluster.

USE CASE 2

Coordinate multi-task batch jobs so all parts start together instead of running one at a time.

USE CASE 3

Run high-performance computing or scientific workloads on Kubernetes without rewriting existing batch infrastructure logic.

USE CASE 4

Replace the default Kubernetes scheduler for one-off, resource-parallel data processing jobs.

What is it built with?
