The Red Hat team has released a new version of the Multi-Arch Tuning Operator.
In Multi-Arch Compute clusters, the Multiarch Tuning Operator influences the scheduling of Pods, so application run on the supported architecture.

Addendum
My colleague, Punith, worked with the Red Hat team to add NodeAffinityScoring and plugin support to the Multi-Arch Tuning Operator and ClusterPodPlacementConfig. This feature allows users to define cluster-wide preferences for specific architectures, influencing how the Kubernetes scheduler places pods. It helps optimize workload distribution based on preferred node architecture.
Spec:
Plugins:
NodeAffinityScoring:
enabled: true
