      Feature Overview (aka. Goal Summary)  

      • Enable the Secondary Scheduler Operator on ppc64le and s390x

      Why is this important?

      • Scheduling is a key component of workload management. Plugins enable customer specific/use case specific decisions to be made when scheduling the workload. e.g., to the closest NUMA node, the proper architecture, and many other decisions.
      • The operator makes it easier to work with Scheduler Plugins and formalizes the support for scheduling changes.

       

      Goals (aka. expected user outcomes)

      As an OpenShift user, I want to schedule work based on plugins, and use the scheduler-plugins via the Secondary Scheduler Operator.

      Requirements (aka. Acceptance Criteria):

      • The Operator installs via the Operator Hub.
      • The Operator is configurable and changes workload scheduling.
      • The plugins load into the OpenShift Container Platform and can be used for decision making when scheduling workloads.

       

      Anyone reviewing this Feature needs to know which deployment configurations that the Feature will apply to (or not) once it's been completed.  Describe specific needs (or indicate N/A) for each of the following deployment scenarios. For specific configurations that are out-of-scope for a given release, ensure you provide the OCPSTRAT (for the future to be supported configuration) as well.

      Deployment considerations List applicable specific needs (N/A = not applicable)
      Self-managed, managed, or both  
      Classic (standalone cluster)  
      Hosted control planes  
      Multi node, Compact (three node), or Single node (SNO), or all  
      Connected / Restricted Network  
      Architectures, e.g. x86_x64, ARM (aarch64), IBM Power (ppc64le), and IBM Z (s390x)
