Allocation Year Rollover: 2014 to 2015
Note: Allocation Year 2014 (AY14) ends at 23:59:59 on Monday, January 12, 2015. AY15 runs from Tuesday, January 13, 2015 through Monday, January 11, 2016.
Below are major changes that will go into effect with the beginning of AY15 on Tuesday, January 13, 2015. All times listed are PST.
Scheduled System Downtimes
Edison will be down from 07:30 Tuesday January 13 until 07:30 Thursday January 15 for memory upgrades. There will be no access to Edison login or compute nodes during this time.
There will be no other service disruptions during the allocation year rollover. Interactive and batch use will continue uninterrupted (except for Edison's downtime, and for "premium" jobs on Edison and Hopper; see below).
Charging Across AY Boundary
All batch jobs will continue running during the rollover. Time accrued before midnight will be charged to AY14 repos; time accrued after midnight will be charged to AY15 repos. Running batch jobs that are associated with non-continuing repositories will have the AY15 component of their usage charged to a NERSC AY15 overhead repository. Queued ("idle") jobs associated with non-continuing repositories will fail upon startup in AY15.
Edison and Hopper Premium Queues Temporarily Disabled
The "premium" batch queues on Edison and Hopper will be stopped at 08:00, Monday, January 5, and will be restarted at 08:00, Tuesday, January 13. During this time, no premium jobs will start, and jobs submitted to the premium queues will be rejected.
AY15 Allocation Awards
The AY15 allocation award letters were e-mailed to project PIs on December 11. The awards are listed on the allocation awards web page. On January 13, the new allocations of CPU time and mass storage will replace those from AY14. Unused allocations do not carry over into the new allocation year.
Users must logout and login again to NIM to get a correct view of AY15 settings. This only applies to NIM sessions that are active at 00:01 on January 13. Also, note that an account usage summary is displayed for users that have logged in to the main NERSC website. This information is acquired from NIM. Therefore, users must logout and login on the main NERSC website for this information to be correct.
When a new repository is created, its initial membership consists of the PI and any PI Proxies that were designated in the ERCAP proposal. The PI and/or Proxies may add other users to the repository after the new AY starts on January 13th and the repository has been activated. Instructions for adding users to repositories can be found in the "NIM User's Guide for PIs" here. In addition, users may now add themselves to repositories; these user initiated additions must then be approved by the PI or by a Proxy. See How to Get a NERSC Account. Users should not submit account requests in new repositories until after the new AY starts and the repository has been activated.
Account Creation/Validation Moratorium
No user accounts will be created or validated after Wednesday, January 7 at noon until Tuesday, January 13 at 08:00. Any such changes made in NIM during this time will not take effect until after AY15 begins.
Effective January 13, a number of current (AY14) users will be considered "discontinued". This can happen for the following reasons:
- A user belongs to only one AY14 project that is not being supported in AY15.
- A user has been explicitly dropped from a repository by the Principal Investigator or Project Manager of that repository.
All discontinued MPP users will have limited login access to their authorized machines until February 13. Such users will be unable to submit batch jobs, but will be able to perform limited interactive tasks. The intent of this access is to allow discontinued users the ability to "clean up", e.g., transfer files back to their home institution.
All discontinued users will continue to have write access to HPSS until February 13, and then limited read-only and delete access for six months (until August 13, 2015). This will allow such users to transfer important data back to their home institution or to active NERSC users and to delete files that are no longer needed.
Deadline for AY14 Startup Requests
Startup awards are small allocations made throughout the allocation year. The deadline for AY14 startup awards is 17:00, Friday, December 19. Any startup requests submitted after this deadline will be for AY15 and will not be processed until after AY15 starts on January 13.
