<b> September 1, 2020, 2:15 PM EST: </b> A short power glitch caused about half of the Niagara compute nodes to lose power; jobs running on them would have failed. Please check your jobs and resubmit.
The maintenance downtime of SciNet's data center has finished, and systems are being brought online now.  You can check the progress here. Some systems might not be available until Friday morning. Login access to Niagara is not yet enabled, but jobs that were in the queue are running.
 
 
 
Some action on the part of users will be required when they first connect again to a Niagara login nodes or datamovers. This is due to the security upgrade of the Niagara cluster, which is now in line with currently accepted best practices.
 
 
 
The details of the required actions can be found on the [[SSH_Changes_in_May_2019]] wiki page.
 
 
 
'''SCHEDULED SHUTDOWN''':
 
 
 
Please be advised that on '''Wednesday May 29th through Thursday May 30th''', the SciNet datacentre will undergo a two-day maintenance shutdown, starting at 7 am EDT on Wednesday May 29th.  There will be no access to any of the SciNet systems (Niagara, P7, P8, BGQ, SGC, HPSS, Teach cluster, or the file systems) during this time.
 
 
 
This is necessary to finish the installation of an emergency power generator, to perform the annual cooling tower maintenance, and to enhance login security.
 
 
 
We expect to be able to bring the systems back online the evening of May 30th.  Due to the enhanced login security, the ssh applications of users will need to update their known host list. More detailed information on this procedure will be sent shortly before the systems are back online.
 
 
 
Fri 5 Apr 2019: Software updates on Niagara: The default CCEnv software stack now uses avx512 on Niagara, and there is now a NiaEnv/2019b stack ("epoch").  
 
  
Thu 4 Apr 2019: The 2019 compute and storage allocations have taken effect on Niagara.  
+
<b> September 1, 2020, 9:27 AM EST: </b> The Niagara cluster has moved to a new default software stack, NiaEnv/2019b.  If your job scripts used the previous default software stack before (NiaEnv/2018a), please put the command "module load NiaEnv/2018a" before other module commands in those scripts, to ensure they will continue to work, or try the new stack (recommended).

September 1, 2020, 2:15 PM EST: A short power glitch caused about half of the Niagara compute nodes to lose power; jobs running on them would have failed. Please check your jobs and resubmit.

September 1, 2020, 9:27 AM EST: The Niagara cluster has moved to a new default software stack, NiaEnv/2019b. If your job scripts used the previous default software stack before (NiaEnv/2018a), please put the command "module load NiaEnv/2018a" before other module commands in those scripts, to ensure they will continue to work, or try the new stack (recommended).
