summary
Explains how the Common Expression Language (CEL) can be used to express granular, extensible scheduling rules across multiple clusters, including matching on labels (e.g., version), CRD fields, and metrics. Describes Open Cluster Management (OCM) using CEL with the ClusterProfile API to meet complex multi-cluster scheduling needs and demonstrates applying CEL-powered policies to improve GPU bin-packing for AI workloads.
