Assumptions:
- For the functionalities involving pbs_sched internal calendaring capabilities (e.g. backfill, reservations) to work properly every job in the complex must declare a required walltime and estimated start time must be enabled.
- It is assumed that PBS will rely on external tools (scripts developed by customers or third party applications) to perform metrics collections and take actions such switch power states of a vnode.
- The total amount of resources in the system is assumed to be constant for the scope of this UCR. No execution vnodes are dynamically created as a result of power management actions.
- Power consumption accounting is assumed to be precise (as far as the platform management tools, scripts developed by customers or third party applications, provide for proper and accurate information) only if jobs are exclusively allocated (vnodes set with sharing=exclusive and/or job submitted with “place=excl”).
