The Multiarch Tuning Operator v1.2.0 is released. 1.2.0 continues to enhance the user experience for administrators of Openshift clusters with multi-architecture compute clusters.
If you’ve ever run an Intel container on a Power node, v1.20 alerts you using an eBPF program that monitors for the ENOEXEC (aka Exec Format Error). It’s super helpful when you are migrating to IBM Power.
You can install Multi-Arch Tuning Operator right from Operator Hub on any cluster 4.16 and higher.
To enable the monitoring configure your global ClusterPodPlacementConfig:
oc create -f - <<EOF
