Dear NERSC users, A 3-yearly power maintenance on the weekend of July 9-12 will impact Cori and possibly auxiliary NERSC systems. To minimise interruptions on Cori, the Cori maintenance originally scheduled for July 21 will be cancelled and instead performed during the July 9-12 power maintenance. During the morning of Friday July 9 Cori will be shutdown, including the cscratch1 filesystem, CoriGPU and large memory nodes. We anticipate that Cori will become available again to users during the afternoon of Monday July 12. We aim to keep $HOME and CFS filesystems, HPSS, and auxiliary services including Iris, Spin, the Data Transfer nodes and Globus endpoints running with our backup generators. However weather conditions may necessitate shutting these down too - we'll know closer to the date how likely we are to face unfavorable weather. The main NERSC website, docs and help ticket system are hosted off-site, so should not be impacted. Regular infrastructure maintenance is crucial to the reliability of NERSC systems and services - thanks for your patience during this upcoming power maintenance. thanks, -- Steve Leak NERSC User Engagement _______________________________________________ Users mailing list Users@nersc.gov
