Allocation Year Rollover: 2015 to 2016
Note: Allocation Year 2015 (AY15) ends at 23:59:59 on Monday, January 11, 2016. AY16 runs from Tuesday, January 12, 2016 through Monday, January 09, 2017.
Below are major changes that will go into effect with the beginning of AY16 on Tuesday, January 12, 2016. All times listed are PST.
Scheduled Systems and Services Downtimes
There will be no computational systems disruptions during the allocation year rollover and jobs will run uninterrupted. No service downtimes are expected, except that the NIM accounting system will be unavailable for about 30 minutes around midnight on Jan 11.
Charging Across AY Boundary
All batch jobs will continue running during the rollover. Time accrued before midnight will be charged to AY15 repos; time accrued after midnight will be charged to AY16 repos. Running batch jobs that are associated with non-continuing repositories will have the AY16 component of their usage charged to a NERSC AY16 overhead repository. Queued ("idle") jobs associated with non-continuing repositories will fail upon startup in AY16.
Edison Premium QOS Temporarily Disabled
Edison has been is made available to users on Jan 4, 2016, premium QOS jobs will have the same priority as normal QOS jobs. The premium QOS will be available again when the new allocation year starts.
Charging for Edison and Cori Begins January 12
Edison and Cori jobs will be charged against Allocation Year 2016 repositories beginning January 12, 2016. The machine charge factor for Edison remains the same (2.0) as before. The machine charge factor for Cori is 2.5. Please see more details on How Usage is Charged.
Cori batch queue configuration will also be adjusted, with smaller submit and run limits in general. Please see more details on Cori Queues and Policies.
SSH Public Keys in NIM
Beginning on January 12, 2016, public-key authentication will be available only to users who have stored their SSH public keys in the NERSC NIM database via the NIM web interface. Public keys stored in $HOME/.ssh/authorized_keys will no longer be honored. This change is being made to enhance system and account security. More details and info on how to test this feature on Cori in advance can be found at the Connecting with SSH page.
AY16 Allocation Awards
The AY16 allocation award letters were e-mailed to project PIs on December 11. The awards are listed on the allocation awards web page. On January 12, the new allocations of CPU time and mass storage will replace those from AY15. Unused allocations do not carry over into the new allocation year, except for ALCC projects. (ALCC projects should see the remainder of their 2015/16 ALCC awards reflected in their NERSC 2016 allocation. 2015/16 ALCC time expires on June 30, 2016.)
Sessions that are active in the NIM web interface at 00:01 PST on January 12, must be refreshed to display accurate information. Sessions can be refreshed by logging out and then logging back in. The same applies for account information displayed on the main NERSC web site.
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 12th and the repository has been activated. Instructions for adding users to repositories can be found in the "NIM User's Guide for PIs". 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 request accounts in new repositories until after the new AY starts.
Account Creation/Validation Moratorium
No user accounts will be created after Wednesday, January 6 at noon until Tuesday, January 12 at 08:00.
Effective January 12, a user will be considered "discontinued" if that user is not associated with an active AY16 repository. (Note: It is possible for a PI or repository manager to drop users from continuing repositories.)
All discontinued users will have limited login access to their authorized systems until February 12, 2016. 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 12, and then read-only and delete access for six months (until August 12, 2016).
Startup awards are small allocations made throughout the allocation year. Startup requests for AY2015 are no longer being accepted.
