Changing job walltime

The latest OAR version installed in Grid'5000 now provides the functionality to request a change to the walltime of a running job (duration of the resource reservation). Such a change is granted with respect to the resources occupation by other jobs and the resulting job characteristics still have to comply with the Grid'5000 Usage Policy¹. You may use the "oarwalltime" command or use the Grid'5000 API to request or query the status of such a change for a job. See the Grid'5000 tutorials² and API documentation³ for more information.

¹ Rules from the Usage Policy still apply on the modified job. We are however considering changing the Usage Policy to take the new feature into account, and would welcome ideas toward doing that. Please feel free to make suggestions on (
