Verifying
Most planned maintenance activities have concluded. PetaLibrary is again available, and Blanca is again running jobs.
We are finalizing bringup for Summit, after which we will perform our regular performance testing before releasing it for use.

Update
The Network Engineering and Operations (NEO) team would like to co-schedule a Science Network change with today's maintenance. This change will likely occur later this morning, and will involve a brief (1-2m) interruption of network communication with SPSC, including Blanca and PetaLibrary.
Further update will provided after this change has been completed.

Scheduled
Research Computing will perform regularly-scheduled planned maintenance Wednesday, 3 April 2019. April's activities include
- Cooling tower cleaning at HPCF - Performance validation of the Summit compute environment - Configuration changes and bugfixes for PetaLibrary/active (BeeGFS) - Acceptance testing of PetaLibrary/active (BeeGFS)
Maintenance is scheduled to take place between 07:00 and 19:00, though service will be restored as soon as all activities have concluded. During the maintenance period no jobs will run on Summit resources, and all Summit resources (including Summit storage) will be unavailable. PetaLibrary/active may also experience periodic outages during testing and fixing. Because of the possibility of PetaLibrary/active outages we have also reserved Blanca compute resources for maintenance; if you would like to continue running on Blanca despite potential PetaLibrary outages, please contact rc-help@colorado.edu and let us know which partition to exempt from reservation.
We apologize for having two such high-impact maintenance outages in a row; we were unable to complete the planned HPCF cooling tower maintenance last week due to inclement weather; and we're finishing up BeeGFS testing and problem fixing at the same time.
