Koordinator vs Volcano
Both stand on gpu cluster management software. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
Choose Koordinator if you need self-hosted Kubernetes scheduling with workload priorities, QoS controls and resource sharing across services and batch jobs. Teams on Kubernetes 1.20 or 1.22 should account for the partial support noted for version 1.8; the core co-location, QoS and scheduling functions continue to work.
