Decommission of HPC Allocated Systems
BC Project: FY12-02
Date of Policy: 16 Apr 2013
Last Updated: 28 Jun 2018 (see Revision Log)
In order to provide the High Performance Computing Modernization Program (HPCMP) user community with consistent policies and notification concerning decommission of allocated HPC resources, all participating HPCMP centers shall adhere to the following practices for HPC system decommissions.
Messages can be customized to fit each center's needs, but at a minimum all centers shall send notices to users at the following lengths of time before decommission:
- 6 months
- 3 months
- 1 month
- 2 weeks
- 1 week
Delivery should occur through multiple channels to provide the widest possible coverage. The following three communication methods reported in BC policy FY06-10 (Standardized User Notices) should be accomplished:
- Message Of The Day (MOTD)
- Web Posting
The batch scheduler job queues will be disabled at midnight (system time) on the established decommission date. All executing jobs will be allowed to run to completion beyond the decommission date. Queued jobs that have not yet begun execution at the decommission boundary will not be allowed to begin execution. The data transfer queue will remain available for one week beyond the decommission date to allow users to archive data.
Data Access Period
Users have one week beyond the decommission date to archive or remove data from the system. At the one week boundary user login access will be terminated. Given that jobs are allowed to run up to a week after the decommission date, users are encouraged to plan accordingly as no additional time for user login access to retrieve output will be available at the end of the run.
