Issue #: 1499 Platform: All Reporter: joga (joga) Component: gridengine OS: All Subcomponent: cleanup Version: current CC: None defined Status: NEW Priority: P4 Resolution: Issue type: ENHANCEMENT Target milestone: --- Assigned to: ernst (ernst) QA Contact: ernst URL: * Summary: Enhance recomputation of consumables Status whiteboard: Attachments: Issue 1499 blocks: Votes for issue 1499: Opened: Tue Mar 15 03:47:00 -0700 2005 ------------------------ When a complex variable is modified, a recomputation of the resource debitation may be required. This is the case, when a variable has been changed from non consumable to consumable and vice versa, or when the default request of a consumable is changed. In this case, the current implementation trashes the resource debitation of all hosts and queues and recomputes all values. It would only be necessary to trash and recompute the values for the affected hosts and queues (where the consumable is actually configured). Only the debitation for the affected variables has to be recomputed. This would significantly improve performance of this action, as - all affected queue instances are spooled - the version number of affected queues is increased, which means that scheduling decisions that have been made on the old queue version will not be accepted and have to be repeated. As the situation in which a recomputation is required, is not really a frequent one, I consider it being a P4 issue.
