This topic describes the components and configurations that are required to enable topology-aware GPU scheduling.


  • A Container Service for Kubernetes (ACK) Pro cluster is created. When you create the cluster, set Instance Type to Heterogeneous Computing. For more information, see Create a professional managed Kubernetes cluster.
    Notice Only ACK Pro clusters support topology-aware GPU scheduling. If you want to enable topology-aware GPU scheduling for ACK dedicated clusters, submit a ticket to apply to be added to a whitelist.
