ACF Timeline

Please note this schedule is subject to change.

Note: This schedule or has been changed to list future events first
  • Future Events
    • June 2018: Working with those who have storage allocations on the Newton /gamma (GPFS) file system to retire this resource from Newton
    • Summer 2018: Work with those users who have remaining storage in /lustre or /data file system on Newton to transition these files to the ACF or other destination. Users should transfer all data on Newton to other resources by the time classes start next Fall.
    • July 10-11, 2018: ACF scheduled for maintenance to update the JICS 116 Data Center Emergency Power Off (EPO) system to include the new Power Distribution Unit (PDU) that has an Uninterruptable Power Supply (UPS). This will affect all ACF resources and the outage is planned for July 11 7am to 5pm. The ACF will be taken down July 10 at about 5pm and returned to service after the maintenance is complete on July 11 in the afternoon.
  • Past Events
    • April 26: 8 additional Skylake nodes added to the ACF - 6 are currently available in production, 2 are reserved for Lustre upgrade testing.
    • April 23: Added the Skylake with a Volta GPU to ACF in partition "skylake_volta"
    • March 22: 2-2:30pm Unplanned complete power outage due to TVA operational issue at ORNL. Power to both building 5100 and 5600 lost. UPS on Haven kept Haven storage from having power interrupted. UPS in K200 did not work properly. Infrastructure power interrupted.
    • March 21: DTNs physically moved from E102 to JICS 116.
    • March 19: 16 Skylake nodes added to the ACF
    • March 16: 8:30am to 12:30pm Unplanned Lustre outage due to power issue. Most all I/O recovered when Lustre was restored. Only a few I/O sensitive jobs were interrupted.
    • March 12 5pm to March 14 5pm: ACF outage to move JICS infrastructure to new location and bring PDU-3 UPS online for storage systems. This was during Spring Break.
    • March 1, 2018: Significant moab scheduler changes.
    • February 28, 2018: Changed the sigma partition to split between "sigma" partition for the 24 core nodes and "sigma_bigcore" for the 28 core nodes.
    • February 21, 2018: Changed the ACF jobs scheduler to increase the reservation depth from 1 to 5. This is the number of jobs that the schedule puts a reservation on specific nodes.
    • January 31, 2018: 9am to noon: ACF Preventative Maintenance to do software fixes and updates.
    • January 17, 2018: Medusa file system retired and taken offline. If you need data from Medusa your have 30 days to submit a ticket.
    • January 5-6, 2018: ACF outage for facilities upgrade.
    • November 18, 2017: ACF /lustre/medusa will be set to read-only. No new files allowed to be created on /lustre/medusa file systems
    • November 17, 2017: ACF outage at 5pm due to new boiler water source added to JICS building. System maintenance will be tied in with this outage. Estimated system back online at 5pm Nov 18th
    • November 1, 2017: Sigma integration complete into ACF. ACF now consists of Beacon, Monster, Rho, Sigma. A few nodes of Rho and Sigma offline due to incomplete hardware.
    • October 25, 2017: Began Sigma integration into ACF
    • October 25, 2017: 8am-5pm Scheduled ACF outage due to building chilled water maintenance
    • October 23, 2017: Newton /lustre and /gamma file systems configured as read-only. No new files allowed to be created on these file systems
    • October 6-9, 2017: Newton offline due to power outage in KPB. Network access to ACF resources at JICS will be affected from campus and most all external locations
    • October 4-6, 2017: The Newton Sigma nodes no longer available for user jobs and are taken offline to be moved to JICS
    • September 14: Users begin migrating Newton files and ACF Lustre Medusa files to ACF Lustre Haven file system
    • September 13, 2017: New Lustre Haven file system scheduled for production use in the ACF at end of day
    • September 11, 2017: Rho nodes integrated into ACF
    • August 14, 2017: Newton Rho nodes are taken offline and moved to JICS
    • August 11, 2017: Monster node integrated into ACF
    • July 28, 2017: One Rho chassis and Sigma chassis taken offline from Newton and moved to JICS
    • July 26, 2017: ACF began with Beacon partition, application for accounts opens
    • July 3-25, 2017: Beacon down for OS upgrades and conversion to ACF
    • July 7, 2017: Newton Monster node was taken offline
