System Status ✓ Niagara ✓ HPSS ✓ BGQ ✓ SGC ✓ P7 ✓ P8 ✓ Teach ✓ Jupyter ✓ Scheduler ✓ SSH Access ✓ File system Current Messages: December 24, 2018, 11:35 AM EST: Most systems are operational again. If you may have had compute jobs running yesterday around 3:30 PM, they likely crashed - please check them and resubmit if needed. December 24, 2018, 10:40 AM EST: Repairs have been made, and the file systems are starting to mounted on the cluster. December 23, 2018, 3:38 PM EST: Issues with the file systems (home, scratch and project). We are investigating, it looks like a hardware issue that we are trying to work around. Note that the absence of /home means you cannot log in with ssh keys. All compute jobs crashed arounf 3:30 PM EST on Dec 23. Once the system is properly up again, please resubmit your jobs. Unfortunately, at this time of year, it is not possible to give an estimate on when the system will be operational again. Downtime Announcement for January 15 and 16, 2019 The SciNet datacentre will need to undergo a two-day maintenance shutdown in order to perform electrical work, repairs and maintenance. The electrical work is in preparation for the upcoming installation of an emergency power generator and a larger UPS, which will result in increased resilience to power glitches and outages. The shutdown is scheduled to start on Tuesday January 15, 2019, at 7 am and will last until Wednesday 16, 2019, some time in the evening. There will be no access to any of the SciNet systems (Niagara, P7, P8, BGQ, SGC, HPSS, Teach cluster, or the filesystems) during this time. Check back here for up-to-date information on the status of the systems. Note: this downtime was originally scheduled for Dec. 18, 2018, but has been postponed and combined with the annual maintenance downtime.
