>
> The Resource Manager (RM) employs a mean work item completion time published
> by the Orchestrator (OR) to predict Job Processes (JP) usage for resource
> allocation. Presently this mean only considers completed work items, not
> active ones, and therefore may not reflect the benefits of more resource
> allocation to a Job.
> A revised algorithm for calculating the work item prediction mean is:
> 1. calculate mean of completed work items
> 2. find active work items > completed mean
> 3. calculate new mean comprising completed + longer active work items
> 4. publish same
