# PriorityClass definitions for NPU preempt/reclaim scheduling
#
# priorityClassName controls who can preempt whom:
#   - Higher value can preempt lower value (strictly greater)
#   - Same value cannot preempt each other
#
# preemptionPolicy controls whether a Pod can preempt others:
#   - PreemptLowerPriority (default): can preempt lower priority pods
#   - Never: cannot preempt anyone, can only wait for free resources
#
# volcano.sh/preemptible annotation controls whether a Pod can be preempted:
#   - "true": can be preempted (Pod-level default)
#   - "false": cannot be preempted (PodGroup-level default)
#   - Pod-level annotation overrides PodGroup-level annotation
