'''SYSTEM DOWNTIME - all systems will be shutdown for datacentre improvements beginning at 0930 on Tuesday (13 Aug)'''. Downtime is expected to last 4 - 6 hrs. As usual, follow progress here. This work has been scheduled for a month and, ordinarily, we would have warned users on Friday. However, given the uncertainty about the filesystem we considered delaying the work and held off with the notification.  Given the progress made over the weekend and the importance of the datacentre work we have decided to proceed as originally scheduled. Tomorrow's work specifically addresses the resiliency of the chiller to power events such as the ones that we experienced Thursday. In particular, the chiller controller will be moved to the 480V UPS, a quickstart feature will be installed to speed up the restart of the chiller after an event and a trigger board which has caused two spurious shutdowns over the past 6 months will be replaced

Sun Aug 11 21:49:03 - GPC is available for use.  There is no /scratch or /project filesystem as we are still trying to recover them. You can use /scratch2 to run jobs in exactly the same way as the old scratch (however the environment variable is $SCRATCH2). New policies for /scratch2 are being set but for now each user is limited to 10TB and 1 million files. /home is unscathed.

Sun Aug 11 15:35:32 - We are implementing a contingency plan for access by GPC users. Should be available within a few hours. There will be a new scratch2 filesystem that can be used for submitting and running jobs. TCS users may have to wait another day for a fix (it is technically impossible to mount the new /scratch2 on the TCS). Unfortunately, nobody will be able to access the original /scratch or /project space and the timeline for attempting to fix and recover those filesystems is virtually impossible to judge (have to deal with new problems as they crop-up and there's no way to know how many problems lie ahead).

System Status

System status can now be found at docs.scinet.utoronto.ca


Mon 23 Apr 2018 GPC-compute is decommissioned, GPC-storage available until 30 May 2018

Thu 18 Apr 2018 Niagara system will undergo an upgrade to its Infiniband network between 9am and 12pm, should be transparent to users, however there is a chance of network interruption.

Fri 13 Apr 2018 HPSS system will be down for a few hours on Mon, Apr/16, 9AM, for hardware upgrades, in preparation for the eventual move to the Niagara side.

Tue 10 Apr 2018 Niagara is open to users.

Wed 4 Apr 2018 We are very close to the production launch of Niagara, the new system installed at SciNet. While the RAC allocation year officially starts today, April 4/18, the Niagara system is still undergoing some final tuning and software updates, so the plan is to officially open it to users on next week.

All active GPC users will have their accounts, $HOME, and $PROJECT, transferred to the new Niagara system. Those of you who are new to SciNet, but got RAC allocations on Niagara, will have your accounts created and ready for you to login.

We are planning an extended Intro to SciNet/Niagara session, available in person at our office, and webcast on Vidyo and possibly other means, on Wednesday April 11 at noon EST.
