Yes, SkyPilot Platform built the scheduler on top of Kueue. There is some shortcoming of Kueue's TAS that you have to resolve, e.g., you cannot do TAS with a Elastic job, which makes the hot swapping not possible for large-scale jobs on NVL72 racks: https://kueue.sigs.k8s.io/docs/concepts/elastic_workload/#li...

"No Topology-Aware Scheduling (TAS) support."

There is another blog talking about this coming soon.
