----------------------------------
Summary: DUCC Resource Manager (RM) does not adequately expand Job
Processes (JPs)
Key: UIMA-4882
URL: https://issues.apache.org/jira/browse/UIMA-4882
Project: UIMA
Issue Type: Improvement
Components: DUCC
Reporter: Lou DeGenaro
Assignee: Lou DeGenaro
Fix For: future-DUCC
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
